AbstractAlcoholic liver disease (ALD) is sometimes referred to as liver disease due to alcohol, alcoholic cirrhosis, alcoholic hepatitis, or Laennec’s cirrhosis (2). It is the most common liver disease in the United States (3). About 2 million people in the U.S. are affected by ALD (4). Approximately two-thirds of the adult American population drinks alcohol and more than 10% of people abuse or are dependent on alcohol (20, 6,). More men than women abuse alcohol at a ratio of approximately 2:1 (6). The typical age range of patients, with a diagnosis of ALD, is between 40 and 50 years with the majority occurring before the age of 60 (7). Though this disease can have devastating effects on the human body, there are treatments and therapies available to remedy the complications and damages caused by ALD. Among these, nutrition plays an important and integral role in managing and even reversing this disease process. In this case study, a 62 year old woman with a long history of alcohol abuse was brought in to the Emergency Department for complaints of chest pain. She was diagnosed as having alcoholic ketoacidosis and alcoholic cirrhosis. She was sent to the Intensive Care Unit (ICU) where they began more comprehensive treatment. During her 22 day hospital stay she also contracted a urinary tract infection (UTI), sustained an iatrogenic pneumothorax, and developed acute kidney injury. The patient also suffered from multiple complications that often accompany alcoholic liver disease including hepatic encephalopathy which resulted in altered mental status.An initial nutrition assessment was completed on December 12, 2012. This was one day after the patient’s admission to the hospital. The assessment included anthropometric measurements, biochemical data, physical exam findings, medical history, list of current medications, and calculations for nutrients and fluids needed. Along with the information gathered, the Nutrition Care Practice Guidelines were followed to establish a nutrition diagnosis, implement interventions, and establish monitoring and evaluation plans. Four follow-up nutrition assessments were completed on December 10th, 13th, 18, and 24th throughout the patients stay at the hospital. She was discharged on December 28. 2012.The patient was ordered an NPO diet on admission. After the placement of a small bore feeding tube, she started on a tube feedings of Nepro 1.8 at 35 mm/hour for 20 hours per day. She was then advanced to a Dysphagia 2 diet after a swallow evaluation by the speech language pathologist (SLP). Her diet was then advanced to mechanical soft as her mental status improved. At discharge the patient was clinically and hemodynamically stable.II. IntroductionI chose alcoholic liver disease as the focus for my case study for a number of reasons. First, I wanted to know more about liver disease and it’s affects on the body in greater detail. Alcohol liver disease can go undetected for a long period of time and frequently the patient will be asymptomatic during the early stages of the disease. The disease process can continue to progress for years before a patient show any signs or symptoms resulting from complications of the disease. It is difficult for clinicians to make a definitive and accurate diagnosis because of the nature of the disease. The disease is also a result of addiction and for this reason, both the diagnosis and treatment of ALD requires an interdisciplinary approach. The disease is directly linked to behavior, lifestyle choices, and other environmental factors. For this reason, the primary treatment, which is cessation from drinking, is a difficult one to achieve.The liver is one of the most complex organs in the body. Resulting damage stemming from the diseased liver, is widespread, detrimental, and often times irreversible. Fortunately, if the patient is able to stop drinking, there are medical treatments and nutritional interventions that can help to restore healthy functioning of the liver and essentially the body as a whole. I hope through researching the disease process, examining the current treatments, available interventions, and information gathered through the study of this patient, to gain a better understanding of ALD and the implications for nutrition therapy.III. The LiverAnatomy: The liver is the largest organ in the abdominal cavity and the most metabolically complex (3). The liver also has the unique ability to regenerate itself. Only 10 to 20% of a functioning liver is needed to sustain life, however complete removal of the liver would result in death within 24 hours (3). It consists of individual microscopic functional units called lobules. The liver weighs approximately 1800 grams in men and 1400 grams in women. The surfaces of the liver are smooth and convex in the superior, anterior and right lateral regions. Indentations from the colon, right kidney, duodenum and stomach are apparent on the posterior surface (8). It is located in the right upper quadrant of the body. The line between the vena cava and gallbladder divides the liver into right and left lobes. The Falciform ligament divides the liver in to the right and left atomic lobes. Each lobe has an independent vascular and duct supply. The lobes are divided into eight segments each containing portal vessels, ducts, and hepatic veins (8). The portal venous system extends from the intestinal capillaries to the hepatic sinusoids. This system carries blood from the abdominal gastrointestinal tract, the pancreas, the gallbladder and the spleen back to the heart, flowing through the liver. The largest vessel in this system is the portal vein (8).The portal vein supplies 70% of the blood flow to the normal liver, but only 40% of the liver’s oxygen supply. The remainder of the blood comes from the hepatic artery, and blood from both vessels mixes in the sinusoids. The liver receives an extraordinary volume of blood; approximately 1.5 liters per minute (8). It is also part of the biliary system along with the gallbladder and associated ducts. This system is sometimes referred to as the biliary tree. The liver, along with the pancreas, is essential to digestion (9). Figure 1. Anatomy of the portal venous system (8).190501905Metabolic FunctionsThere are more than 500 functions the liver performs in the body. Hepatocytes, cells in the liver, are responsible for these metabolic functions (3). A selection of the liver’s many functions will be discussed in the following section.One highly important role of the liver is the regulation of carbohydrate homeostasis in the body. Galactose and fructose, products of carbohydrate digestion, are converted into glucose. Glucose is then stored in the liver as glycogen and returned to the blood when glucose levels are low (3). Hepatocytes also contain enzymes that allow for the synthesis of glucose from precursors such as amino acids, pyruvate, and lactate through the process of gluconeogenesis (6). The liver is involved in lipid metabolism as well, where fatty acids are broken down and triglycerides are synthesized. Triglyceride synthesis occurs when carbohydrate intake exceeds energy needs. Triglycerides in adipose tissue are hydrolyzed to release fatty acids. In the blood, the fatty acids are bound to albumin and removed by the hepatocyte (10). As an important contributor to the digestive system, the liver secretes bile salts which are necessary for fat digestion and absorption (9). The liver is also responsible for cholesterol metabolism by synthesizing bile salts from cholesterol, which are secreted in bile and mixed with intestinal contents after a meal. Triglycerides enter the duodenum in the form of an emulsion, the surface of which is covered by a layer of phospholipids and proteins that must be removed by bile salts in order for lipolysis to take place. The products of lipolysis form micelles with bile salts and promote the intestinal uptake of long-chain fatty acids. In the absence of bile, however, the absorption of short- and medium-chain fatty acids occurs. After the uptake of fatty acids, the bile salts are recycled through enterohepatic circulation. Some bile salts are reabsorbed from the distal small bowel by an active, sodium-dependent process. Other bile salts are absorbed by passive diffusion from the proximal small bowel. The liver extracts these reabsorbed bile salts from the portal vein blood and returns them to the biliary tree. The biliary tree is made up of the bile ducts and the gallbladder. Hepatic synthesis of bile salts replenishes the amount of bile salts that are not reabsorbed or are excreted in the feces (10). The liver is central to the breakdown and synthesis of protein. Plasma proteins such as albumin, transferrin, and coagulation factors make up approximately half of the protein synthesized in the liver. The secretion of plasma proteins called thrombopoietin which are involved in platelet formation and hepcidin which inhibits intestinal iron uptake as well as the production of enzymes and insulin-like growth factor-I which stimulates growth are all functions of the liver. Protein synthesis in the liver is affected by nutritional status as well as hormones, and alcohol. Insulin and steroids stimulate protein synthesis whereas glucagon promotes their degradation. 66675135255Figure 2. The liver and associated biliary tree (11)The liver is involved in the storage, activation, and transport of many vitamins and minerals. All fat soluble vitamins, vitamin B12, minerals, including zinc, iron, copper, and magnesium are stored in the liver (3). Vitamin D is activated by the liver as well as by the kidneys.Bilirubin, which is the metabolic end product from the destruction of red blood cells, is also excreted by the liver (3). Detoxifying the body of drugs, alcohol, hormones, removing bacteria and debris from the blood is another function of the liver (12,9). Hepatocytes detoxify ammonia by converting it to urea which is then mostly excreted by the kidneys (3). IV. Alcoholic Liver DiseaseRisk FactorsSeveral variables predispose a person to alcoholic liver disease. The main factors that contribute to ALD are quantity and duration, usually more than eight years of use, gender, genetic and metabolic traits, and nutritional status. The amount of alcohol ingested, independent from the type of alcoholic beverage that is consumed, is the most important risk factor for the development of alcoholic liver disease (5). Women are more susceptible to ALD even when adjustments for body size are accounted for (6). It takes less time and lower doses of alcohol exposure to cause liver damage in females than in males (4). One reason for the increased susceptibility may be that women have less alcohol dehydrogenase in their gastric mucosa. Alcohol dehydrogenase is an enzyme necessary for the oxidation of alcohol and therefore the rate of alcohol metabolism is decreased in females (6). Although the majority of patients are males, men are twice as likely as women to abuse alcohol (7). Protein-energy malnutrition increases susceptibility as well as a diet high in unsaturated fat and obesity (6). Other factors include type of alcohol consumed, drinking pattern, ethnicity, iron overload, simultaneous exposure to other drugs, immunologic factors, and infections such as viral hepatitis (5). Hispanics, more than any other ethnicity, have an increased risk of developing ALD (7). Genetic alterations to alcohol-metabolizing enzymes, including alcohol dehydrogenase and acetaldehyde dehydrogenase, can affect the likelihood of developing ALD as well (5). Environmental factors such as availability of alcohol and social acceptability of alcohol use can also increase the prevalence of ALD (13). However, not all heavy drinkers develop ALD and a person does not have to get drunk in order for the disease to develop (2). Up to 40% of individuals with modest alcohol intake, that is less than or equal to 10 grams per day, exhibit fatty changes to their liver (6). Alcohol content is estimated by multiplying the beverage volume in milliliters times the percentage of alcohol. Therefore 40 mL of an 80 proof beverage, or 40% alcohol contents, is 16 mL. Each mL contains about 0.79 grams of alcohol (6). Based on an autopsy series of men, 40 grams of alcohol per day is necessary to produce pathologic changes of ALD. This would be equivalent to three to six cans of beer, three to six shots of hard liquor, or four to eight glasses of wine per day (6). One in five heavy drinkers develops alcoholic hepatitis, and one in four heavy drinkers develops cirrhosis. A daily dose of more than 60 grams of alcohol in men and 20 grams in women significantly increases the risk of cirrhosis (13). In practice most patients with alcoholic hepatitis drink more than 100 grams per day with 150-200 grams per day being common (7). Table 1. Alcohol Content of Some Common Beverages (3)DrinkAmount (oz)Absolute Alcohol (g)Beer1212Wine512Liquor (80 proof)1.512Alcohol MetabolismThe liver and the gastrointestinal tract are the main sites of ethanol metabolism. Ethanol is the type of alcohol in alcoholic beverages. It is easily absorbed from the stomach but the majority is absorbed by the small intestine and cannot be stored in the body. A fraction of the alcohol ingested is degraded as it passes through the gastric mucosa, but most is metabolized by the liver (6). Within the liver there are two main oxidative pathways of alcohol metabolism. One is through the use of alcohol dehydrogenase (ADH) and the second is with cytochrome P-450 (CYP) 2E1. To a lesser degree, alcohol is also catabolized by a third pathway, the microsomal enzyme oxidation system (MEOS) (6). The major oxidative pathway for alcohol metabolism in the liver involves ADH (14). Alcohol dehydrogenase is a hepatocyte enzyme that converts alcohol to acetaldehyde. Acetaldehyde is a toxic byproduct of alcohol metabolism that causes damage to the structure and function of mitochondrial membranes (3). Acetaldehyde is produced with the transfer of hydrogen to nicotinamide adenine dinucleotide (NAD), reducing it by two electrons to form (NADH). This altered proportion of NAD to NADH inhibits gluconeogenesis and fatty acid oxidation, therefore contributing to fatty liver (13). CYP 2E1 is the main enzyme involved in ethanol metabolism when there are elevated concentrations of ethanol. Through this oxidative pathway, ethanol is also converted to alcetaldehyde. Through this pathway, free radicals are generated by the oxidation of nicotinamide adenine dinucleotide phosphate (NADPH) which is the reduced form to NADP which is the oxidized form (3). The alternative pathway for ethanol metabolism is the MEOS. This pathway also oxidizes ethanol to form acetaldehyde and requires the oxidation of NADPH to NADP. In most individuals this pathway only plays a minor role but in chronic alcohol consumption the activity of this pathway is increased (14). When induced, the MEOS pathway can account for 20% of alcohol metabolism (6). This pathway generates harmful reactive oxygen species which increases oxidative stress and the formation of oxygen free radicals (6). Due to the oxidation of NADPH to NADP, adenosine triphosphate (ATP) is used and heat dissipated. Some researchers believe this contributes to increased resting energy expenditure in chronic alcohol drinkers (14). Alcetaldehyde, formed from these pathways, is then metabolized mainly by aldehyde dehydrogenase 2 (ALDH2) to form acetate which is released into the blood and NADH. Reactive oxygen species are also produced which contribute to oxidative stress (13, 14). Many metabolic disturbances occur because of this excess NADH. These include increased lactic acid in the blood, acidosis, hyperuricemia, ketonemia, and hyperlipidemia. The tricarboxylic acid (TCA) cycle is also depressed as it requires NAD. The mitochondria in turn, use hydrogen from ethanol rather than from the oxidation of fatty acids to produce energy via the TCA cycle, which leads to decreased fatty acid oxidation and the accumulation of triglycerides. Hypoglycemia can also occur in early alcoholic liver disease secondary to the suppression of the TCA cycle along with decreased gluconeogenesis (3). However, it is still not completely understood how alcohol metabolism itself is linked to the genesis of ALD (15). It is also not understood why only a minority of alcoholics develop alcoholic hepatitis (7).Maldigestion/Malabsorption Alcoholics are malnourished because they either eat poorly or alcohol metabolism prevents them from properly absorbing, digesting, and using nutrients (4). Portal hypertension, a common complication of chronic alcoholism, also leads to impaired absorption of nutrients (16). Classic effects of malnutrition from alcoholism include Wernicke’s encephalopathy, Korsakoff psychosis, muscle wasting, weight loss, and liver disease (4). Fat or triglycerides accumulate throughout the hypatocytes for a number of reasons. First, the export of fat from the liver is compromised. This is because hepatic fatty acid oxidation and lipoprotein production is decreased. Second, due to the decreased export of fat from the liver, peripheral lipolysis is increased and the input of fat is increased. This, in turn, increases triglyceride synthesis and results in hyperlipidemia (6). Glucose tolerance is usually abnormal in these patients and has been linked to insulin resistance. During fasting, fatty acid oxidation appears to supplement glucose due to depleted glycogen stores found in a fatty liver (10). Another reason is acetyl CoA, a product of glycolysis, may not be needed for oxidative phosphorylation and therefore is converted to fatty acids and ultimately triglycerides. These triglycerides are then transported to the adipose tissues as part of very-low-density lipoproteins (VLDLs) (10). In summary, hepatic steatosis is caused by the following metabolic disturbances: increased mobilization of fatty acids from adipose tissue; increased hepatic synthesis of fatty acids; decreased fatty acid oxidation; increased triglyceride production; and trapping of triglycerides in the liver (3).Bile salts involved in fat digestion are decreased resulting in impaired micelle formation which leads to fat absorption abnormalities. This is exacerbated in patients with underlying pancreatic insufficiency and can result in steatorrhea and poor absorption of fat-soluble vitamins, thiamin, folic acid, vitamin B12, and zinc (J, K). Thiamin deficiency is the most common vitamin deficiency in alcoholics and is responsible for both Wernicke’s encephalopathy and Korsakoff psychosis (3). Heavy alcohol consumption leads to decreased levels of hepatic vitamin A. Defects have also been noted in the phosphorylation of thiamin, the synthesis of retinol-binding protein, and the conversion of vitamin D to its active form. Induced hepatic microsomes may enhance the breakdown of both retinol and retinoic acid related to vitamin A (10). Protein loss in patients with ALD is common and can be attributed to the following: diuretic use or the procedure of paracentesis both commonly indicated for the treatment ascites, the use of lactulose which is prescribed in to alter intestinal flora, blood loss from esophageal and gastric varices, and ulcerations in the intestinal lumen (16). Glycogen stores are depleted in cirrhotic liver and therefore peripheral muscle will provide amino acids for gluconeogenesis. Therefore patients with alcoholic cirrhosis go into an early starvation mode after only 12 hours of fasting while normally it takes 2 days in normal subjects (17). Metabolism of protein is also defective in patients with ALD and contributes to loss of protein stores. Metabolic processes affected include hepatic synthesis of export proteins, decreased urea synthesis, and decreased metabolism of aromatic amino acids. A decrease in plasma proteins may cause lower levels of albumin and can exacerbate ascites in patients who have portal hypertension. Lower levels of coagulation factors may predispose patients to risk of gastrointestinal bleed. The liver’s inability to detoxify ammonia and the imbalanced amino acid levels could increase the risk for hepatic encephalopathy (10). The effect of ethanol on protein metabolism, measured as nitrogen balance, is nitrogen sparing when ethanol is given as additional calories but causes increased urea when given as a substitute for carbohydrates. Ethanol interfers with amino acid absorption in the gut. It causes impaired hepatic amino acid uptake, decreased gluconeogenesis, impaired synthesis of lipoproteins, albumin, and fibrinogen. Over time ethanol impairs protein secretion from the liver (10). Inflammation and Oxidative StressAlcohol-induced liver injury is an immunological response of the liver; neutrophils damage liver cells through cytotoxicity (4). Inflammation results from the formation of neoantigiens, resulting from the binding of alcohol oxidation products, such as acetaldehyde, to liver cell proteins. There is also an accumulation of neutrophils and other white blood cells that are attracted by lipid perioxidative damage and these neoantigens. The white blood cells then secrete inflammatory cytokines causing inflammation (6). Worsening inflammation leads to cell necrosis and apoptosis which results in hepatocyte loss. Stellate cells in the liver proliferate and transform into myofibroblasts which produce excess collagen. As a result the sinusoids narrow limiting blood flow within the liver. Fibrosis narrows the terminal hepatic venules or central veins, compromising distribution of blood within the liver, which contributes to portal hypertension. Extensive fibrosis is associated with an attempt at regeneration, resulting in liver nodules. This process culminates into cirrhosis (6). Chronic alcohol intake also activates hepatic macrophages which then produce tumor necrosis factor-alpha (TNF-alpha). TNF-alpha induces mitochondria to increase production of reactive oxygen species or peroxides. This oxidative stress promotes hepatocyte necrosis which is exacerbated by probable lack of antioxidants, particularly in the protective antioxidants glutathione, vitamins A and E. Free radicals initiate lipid perioxidation which causes inflammation and fibrosis (13). Bacteria in the gut produce endotoxins which are normally detoxified by the liver but the impaired liver function increases the presence of these endotoxins. In response, liver macrophages release free radicals, increasing oxidative damage (6). If there is an accumulation of iron in the liver, this can also contribute to oxidative damage.DiagnosisThe diagnosis of ALD is based on a combination of factors including history of alcohol intake, clinical evidence of liver disease, and laboratory abnormalities (5). No single laboratory marker definitively establishes alcohol as the cause of liver disease (5). A variety of scoring systems have been used to assess the severity of ALD. Patients can be screened for alcoholism using the CAGE questionnaire which stands for need to Cut down, Annoyed by criticism, Guilty about drinking, and need for a morning Eye-opener (6). Table 2. CAGE Questionnaire (18).The CAGE questionnaire 1. Have you ever felt you should cut down on your drinking?2. Have people annoyed you by criticizing your drinking?3. Have you ever felt bad or guilty about your drinking?4. Have you ever had a drink first thing in the morning to steady yournerves or to get rid of a hangover (eye-opener)?Scoring: Each response is scored as 0 or 1, with a higher score indicative of alcohol-related problems, and a total of greater than or equal to 2 being clinically significant.Both the Maddrey discriminant function and the Model for End-Stage Liver Disease (MELD) score can be useful in predicting short-term mortality in patients with alcoholic hepatitis (13). The MELD score predicts short-term survival in patients with cirrhosis and is used to select patients for liver transplantation. The MELD classification is more difficult to apply for every patient but is widely used and is generally accepted among physicians. This method also excludes undernutrition as a contributor to the score (7). The Maddrey’s discriminant function is calculated as total bilirubin (in mg/dL) + 4.6 x prothrombin time in seconds prolonged. This tool was published in 1978 based on laboratory and clinical data collected from studies in the 1960’s and 1970’s. It was then modified in 1989 so that a discriminant function score of greater than 32 signified severe alcoholic hepatitis and the need for drug treatment (7). The Lille model is another prognostic scoring system that is more accurate than the MELD score for predicting death at six months in patients with severe alcoholic hepatitis. The Lille score is based on pretreatment data and serum levels of bilirubin as compared to a seven day course of corticosteroids. This score is designed to help the clinician decide whether to stop corticosteroids after the one week of administration or to continue the treatment. A Lille score of greater than 0.45 indicates a lack of response to corticosteroids and predicts a six month survival rate of less than 25% (15). To identify patients at risk of early mortality from alcoholic hepatitis clinicians also use the Glasgow Alcoholic Hepatitis score (4). In 2005 investigators from Glasgow reported the results of an analysis involving a large cohort of patients with ALD identifying variables related to survival at 28 days and 84 days after hospital admission. From the results of this study they developed the Glasgow alcoholic assessment (15). The Glasgow Alcoholic Scale is a five-item scale using four laboratory values, bilirubin blood urea, nitrogen, prothrombin time and WBC count along with patient age to score the severity of alcoholic hepatitis. The study based on 200 people showed that a score of 9 or higher on the Glasgow alcoholic hepatitis scale indicated having an increased mortality rate; these patients had improved survival rate with corticosteroid therapy (7). The easiest and most globally recognized methods for assessing clinical status and severity of disease in patients with liver cirrhosis are the Child-Plugh classification and the model for end stage liver disease (MELD). The Child-Plugh classification was derived from the Child-Turcotte classification which was used up to the early seventies and recognized five factors that affect prognosis and survival. These five factors are ascites, hepatic encephalopathy, and levels of bilirubin, albumin and prothrombin time. Unfortunately this classification system does not evaluate for nutrition status. It is the most common and feasible method in categorizing cirrhotic patients (16). Table 3. Prognostic Scoring System used for patients with alcoholic hepatitis (19).

The presence of certain features may help to include advanced liver disease as a possibility but indicators specific to ALD are more difficult to identify. Just as no single lab value is definitive for diagnosing ALD, neither is any single physical finding or collection of findings. It is important for physicians to recognize that ALD does not exist on its own. Other organ dysfunctions related to alcohol abuse may coexist with ALD including: cardiomyopathy, skeletal muscle wasting, pancreatic dysfunction, and alcoholic neurotoxicity (5). General symptoms vary based on the severity of the disease. Alcoholic liver disease progresses in three stages: hepatic steatosis, alcoholic hepatitis, and lastly cirrhosis. Hepatic steatosis, occurs in more than 90% of patients, alcoholic hepatitis seen in 10 to 35%, and lastly cirrhosis is prevalent in 10 to 20% of patients seen (6). Physical examination usually reveals a malnourished patient with a fever, low blood pressure and tachycardia. There is a high prevalence of jaundice and ascites and a significant number who present with hepatic encephalopathy (7). Symptoms can include: abdominal pain and tenderness, dry mouth, increased thirst, fatigue, jaundice, loss of appetite, nausea, swelling or edema in the legs or ascites in the presence of cirrhosis, and weight loss. Changes in skin include: abnormal darkening or lightening of the skin, redness of feet or hands, and spider angiomas which are spider-like blood vessels on the face, back or belly (2, 4). Abnormal bleeding can occur as well. This can appear as melena, nosebleeds, bleeding gums and vomiting blood or material that looks like coffee grounds (2). In the brain and nervous system symptoms such as agitation, mood changes, confusion, poor judgment, shortened attention span, or encephalopathy can occur. This can result in periods of decreased alertness or awareness of one’s surroundings, hallucination and impaired memory, including both short-term and long-term memory. Pain, numbness, or tingling in the extremities can occur as well as slow or sluggish movements. In men, altered hair patterns and gynecomastia or breast development in males, may occur (4).The first stage hepatic steatosis, also called fatty liver and is often asymptomatic. In one third of patients the liver is enlarged and smooth but not usually tender (6). Hepatic steatosis is reversible if abstinence from alcohol is achieved for approximately 4 to 6 weeks (5). Alcoholic hepatitis is the second stage and is generally characterized by an enlarged liver (3). This stage is considered an acute form of alcohol-induced liver injury that occurs with a large intake of alcohol over a prolonged period of time. Alcoholic hepatitis encompasses spectrum of severity ranging from alterations in biochemical factors to sudden and severe liver failure as well as death (13). Labs specific to this stage of ALD include an elevation of transaminase levels, increased serum bilirubin concentrations, normal or low serum albumin concentrations, or anemia (3). AST is greater than the ALT and usually less than 400 IU/mL. Total and direct bilirubin levels are elevated, with bilirubin exceeding 15 mg/dL. In severe cases, serum sodium and albumin are low, while INR is elevated. WBC count is elevated sometimes to >1500/mm3 (7). Signs and symptoms that patients may experience are abdominal pain, anorexia, nausea, vomiting, weakness, diarrhea, weight loss or fever. If alcohol consumption is discontinued, this condition could improve. However, more frequently, it will progress to the third and final stage (3). Alcoholic cirrhosis is the third stage and can present with varying symptoms as well. In some patients, the symptoms are similar to those of alcoholic hepatitis. For other patients, symptoms can be more severe and include gastrointestinal bleeding, hepatic encephalopathy, or elevated blood pressure in the portal venous system or portal hypertension (3). The elevated blood pressure is caused by the obstruction of blood flow through the liver (3). Portal hypertension may lead to cyanosis and nail clubbing (6). Ascites is often times present as well. Ascites is the accumulation of fluid, serum protein, and electrolytes within the peritoneal cavity. It is caused by the increased pressure from the portal hypertension and decreased production of albumin. Albumin maintains serum colloidal osmotic pressure or the osmotic balance between the cells and the blood in the body (3). During alcoholic cirrhosis, there is a replacement of normal hepatic parenchyma with extensive thick bands of fibrous connective which result in the clinical manifestations of portal hypertension and liver failure (13). There are many complications of cirrhosis including: malnutrition, hyponatremia, hepatic encephalopathy, glucose alterations, fat malabsorption, hepatorenal syndrome, and osteopenia. Figure 3. Stages of Liver Damage (20).If the patient remains abstinent, fatty liver resolves within six weeks (6). If the disease had not progressed to cirrhosis, the liver can heal with the cessation of drinking. Fibrosis and cirrhosis are irreversible. Once cirrhosis has developed, the complications of this advanced stage will require management and a liver transplant may be needed (2). There are two stages of cirrhosis, compensated and decompensated. Compensated cirrhosis indicates that despite the scarring the liver tissue, the body still functions and the patient has few symptoms or is asymptomatic. When there is severe scarring of liver and body functions are disrupted, this is classified as decompensated cirrhosis. Patients at this stage may develop serious and even lethal symptoms and complications (21). Biochemical Markers:Biochemical markers are used to evaluate and monitor patients having or suspected of having liver disease. Enzyme assays measure the release of liver enzymes and other tests measure liver function. Screening tests include: serum levels of bilirubin, alkaline phosphatase, aspartate aminotransferase (AST), and alanine aminotransferase (ALT) (3). Serum AST is typically elevated to a level of 2 to 6 times the upper limits of normal in severe alcoholic hepatitis (5). Ratios of AST/ALT which are greater than 3 are highly suggestive of ALD (5). Typically the ratio of AST to ALT is approximately 2:1 (13). The basis for low ALT is a dietary deficiency of pyridoxal phosphate or vitamin B6, which is needed for ALT to function (6).Serum y-glutamyl transpeptidase (GGT) increases due to ethanol which induces this enzyme. Serum albumin may be low, usually reflecting undernutrition but sometimes is representative of liver failure with deficient synthesis. Macrocytosis with Mean Corpuscular Volume (MCV) greater than 100 fL reflects the direct effort of alcohol on bone marrow as well as macrocytic anemia resulting from folate deficiency. Indexes of the severity of liver disease are serum bilirubin which represents secretory function and Prothrombin Time (PT) or International Normalized Ratio (INR) which reflects synthetic ability (6). Other common laboratory abnormalities include anemia and leukocytosis (13). Serum tests for ferritin and iron are often unreliable due to hepatic inflammation and hepatocyte death (7). Table 4.

Instead, these tests are used to rule out other causes of abnormal tests in a patient who abuses alcohol. These imaging tests include: ultrasound, CT scan, or magnetic resonance imaging (MRI). Magnetic resonance imaging has been used to diagnose cirrhosis and to distinguish end-stage liver disease that is related to a viral hepatitis infection from ALD (5). Biopsy:A liver biopsy is sometimes needed to secure the diagnosis. A clinical suspicion of alcoholic hepatitis may be inaccurate in up to 30% of patients (13). If the disease is not decompensated, clinical and biochemical markers are not reliable for determining the severity of the disease and a biopsy is needed in establishing the stage and severity of the disease (5). In addition to confirming the diagnosis, a liver biopsy may help to rule out any other possible causes of liver disease. A liver biopsy aids in assessing the extent of the damage, making a prognosis, and offering appropriate therapies (13). However sometimes the risks involved with doing a biopsy may influence the incentive to make a histological diagnosis (5). Treatment:The most important part of treatment is to stop using alcohol completely and as soon as possible. Compliance to abstinence is difficult and therefore a team approach is key. This approach includes incorporating services from behavioral and psychological therapies as well as integrating rehabilitation programs and support groups. Brief interventions by primary care physicians may also be a component to treatment (6). Patients with alcoholic hepatitis, who discontinue drinking alcohol, live significantly longer than those who continue to drink. Three year survival nears 90% in those who sustain from drinking alcohol and less than 70% in those who continue to drink (13). The 28 day mortality for alcoholic hepatitis ranges from 30% to 50% (7). Clinical and laboratory features are powerful prognostic indicators for short-term mortality. Hepatic encephalopathy, alterations in renal function, hyperbilirubinemia, and prolonged prothrombin time are seen more often in patients who die from the illness than in those who survive (13).Part of the therapy for ALD is treating the complications of the disease. Generally ascites can be decreased through the use of diuretics and a salt-restricted diet. The use of lactulose and antibiotics to kill bacteria in the gut are treatments for hepatic encephalopathy. Any outside infections should be addressed and treated with the recommended antibiotics. Hepatorenal syndrome should be treated with albumin and vasoconstrictors (15).Medications:Medications may be prescribed to aid in maintaining abstinence but are only recommended along with the other healthcare interventions, as mentioned above. Disulfiram (Antabuse) is given with patients’ consent. It causes the patient to vomit after ingesting alcohol and could be dangerous (4). Naltrexone was approved in 1995 however it has also been shown to cause hepatocellular damage. However, in a systematic review of the medication, the risk of relapse was lowered with short-term use (5). Short-term abstinence is improved by the use of naltrexone at 100 mg per day (7). Baclofen has been proven safe in clinical trials, whereas the safety of naltrexone or acamprosate in the treatments of patients with alcohol-related liver failure has not been established (15).Supportive care is at the core of managing the disease and the complications involved. Alcohol withdrawal requires the use of benzodiazepines except in patients with advanced ALD, as excessive sedation can contribute to hepatic encephalopathy (6). Opioid antagonists, such as naltrexone, or nalmefene and drugs that modulate y-aminobutyric acid (GABA) receptors, including baclofen or acamprosate, may have a short-term benefit by reducing withdrawal symptoms and cravings (6). Naltrexone is more effective in some individuals than in others. Delirium tremens can also be treated with benzodiazepines (15). Severe acute alcoholic hepatitis commonly requires hospitalization and often an intensive care unit. Here enteral feeds can be initiated to help manage nutritional deficiencies and certain complications can be monitored more carefully. These complications can include infections, bleeding esophageal varices, electrolyte imbalances, ascites, and hepatic encephalopathy (6). Beta-blockers such as propranolol or nadolol or octreotide, brand named Sandostatin, may be used to reduce portal hypertension when varices occur. Insulin may be necessary to regulate blood sugars but should not be mixed with ethanol and therefore is not recommended for patients who continue to drink alcohol. Alcohol intake may cause severe hypoglycemia in patients taking insulin. Metformin should be avoided with patients with liver disease as well (4). Corticosteroids have become the standard of care in patients with severe alcoholic hepatitis. The concept behind this pharmaceutical therapy is the suppression of the immune system to prevent further hepatic damage. Practice guidelines support the use of corticosteroids in those who have a diagnosis of severe alcoholic hepatitis with no signs of infection, gastrointestinal bleeding, renal failure, or pancreatitis (13, 6). The most common corticosteroid therapy for ALD is prednisolone at 40 mg per day for 28 days. The patient will either be taken off the medication all at once or slowly tapered off over a three week period. Unfortunately alcoholic hepatitis is unresponsive to corticosteroid treatment in approximately 40% of patients. The mechanism of action is believed to decrease transcription of pro-inflammatory cytokines such as TNF-alpha. Indications include discriminant function (DF) > 32, MELD score > 20, Glasgow score > 8 or the presence of hepatic encephalopathy (7). No other treatment has been shown to be more effective with this group of patients (15). Methylprednisolone, a corticosteroid, improves the ability to produce albumin and to normalize prothrombin time (PT) and bilirubin levels. Side effects of this treatment may include negative nitrogen balance, hypocalcemia, or hyperglycemia (4).Research into pentoxifylline, an inhibitor of TNF-alpha synthesis, has been used in studies as a possible treatment since increased levels of TNF-alpha have been found to be linked to a higher mortality from alcoholic hepatitis (13). Pentoxifylline is a nonselective phosphodiesterase inhibitor which indirectly decreases expression of cytokines such as TNF-alpha, interleukin 8 (IL-8) and macrophage inflammation (7). Pentoxifylline at 400 mg three times per day for 28 days is an alternative treatment of alcoholic hepatitis; indications for treatment are similar to corticosteroids. A potential benefit is that it can be used in patients with infection and patients with renal insufficiency (7). Anabolic steroids such as oxandralone and testosterone have been tested in attempts to increase the incorporation of nutrients into muscle mass in alcoholic hepatitis but there has not been enough supporting data to put into practice. Also colchicine, an anti-fibrotic, anti-inflammatory, often used to treat gout, has been tried but failed as well (7). Neither oral administration of colchicines or propylthiouracil or combined regimen of insulin and glucagon, is effective in patients with alcoholic hepatitis (15).In liver disease the activation of methionine to S-adenosylmethionine (SAMe) is impaired. Folate deficiency accentuates abnormal methionine metabolism, lipid oxidation, and liver injury. Trimethylglycine (TMG) or betaine is manufactured by the body. It helps to break down homocysteine. Plasma homocysteine levels are altered in actively drinking patients casuing brain atrophy and withdrawal seizures. Common recommendations for betaine range from 375 to 3,000 mg daily. Betaine may help to protect the liver against the effects of alcohol, perhaps by stimulating the formation of SAMe. However betaine also seems to worsen cholesterol profile and this may counteract any possible benefits (22). Betaine may lessen damage of ALD by increasing synthesis of SAMe and glutathione, decreasing homocysteine (tHey) level. SAMe, betaine, and folate decrease oxidative stress by upregulation of TNF-alpha however more research is indicated (4).Alternative Therapies:Antioxidants are often recommended as part of the treatment of ALD due to the presence of oxidative stress and the reduction in antioxidant capabilities. Also, N-acetylcysteine an antioxidant, has been proven effective as a treatment for acetaminophen-induced acute liver failure (7). Studies involving treatment with antioxidants however, including vitamin E and silymarin, which is the active ingredient in milk thistle, have not shown any survival benefit in either patients with alcoholic hepatitis or alcoholic cirrhosis (15).Numerous double-blind, placebo-controlled studies enrolling a total of several hundred people have evaluated whether the herb milk thistle can successfully counter alcohol-induced liver damage. These studies have yielded inconsistent results. A 2007 review of published and unpublished studies on milk thistle as a treatment for liver disease concluded that benefits were seen only in low-quality trials and even in those milk thistle did not show more than a slight benefit. A subsequent 2008 review of 19 randomized trials drew a similar conclusion for ALD generally, although it did find a modest reduction in mortality for patients with severe liver cirrhosis (22). Curcuma longa or turmeric and Glycyrrhiza glabra which is licorice, have also been evaluated for effectiveness but studies have been inconclusive. Tea polyphenols, especially green tea, may alleviate liver damage but further testing is needed. Chaparral is especially toxic to the liver and should be avoided. Aloe vera, has been evaluated but should not be administered orally (13). Other herbs and supplements that may possess known or suspected liver-toxic properties include: excessive doses of beta-carotene and vitamin A which might cause alcoholic liver disease to develop more rapidly in people who abuse alcohol; coltsfoot, comfrey, germander, greater celandine, kaya, kombucha, pennyroyal, and prepackaged Chinese herbal remedies (22). Nutritional supplementation at the standard daily requirement level should not cause a problem. Herbs and botanical supplements should only be used when discussed with a physician.Transplant:A patient is appropriate for transplant when the disease has advanced to decompensated cirrhosis, evidenced by the presence of ascites, spontaneous bacterial peritonitis, hepatic encephalopathy, and variceal bleeding. For patients with decompensated alcoholic cirrhosis who undergo transplant, survival is comparable to that of patients with other causes of liver disease; 5 year survival rate is about 70% (13). Alcoholic hepatitis, the second stage of ALD, has been considered an absolute contraindication to liver transplantation due to the fact that the patients with this disorder have been drinking recently and a period of abstinence will allow many to recover (15). Most U.S. transplantation programs now require 6 months of abstinence before a patient with alcoholic hepatitis can become eligible for transplant (15). There is always a concern that the patient will return to alcoholism after transplantation. Also, recidivism depends on the definition of alcohol use. Approximately 20-40% of alcoholics consume some degree of alcohol after transplant with up to 25% returning to abusive drinking habits (7). There is a high cost and limited availability of cadaveric livers associated with transplantations.Support groups and therapy are a cornerstone to the treatment of ALD. Chemical addiction is a disease. Self-help programs and follow-up with professionals can reduce dependency (4). The dietitian or other healthcare providers need identify sources of assistance for those who need help with meal preparation, access to food, medication, and post-discharge medical care (4). V. Medical Nutrition TherapyRole of the Registered DietitianThere are several components to the nutrition intervention for which the dietitian is responsible. First, is to ensure adequate nutrients are provided in the meal plan and with supplementation if needed. Second, is to provide enteral and/or parenteral support when appropriate. Third, is to assess whether or not limitation of certain nutrients is needed to manage cirrhotic complications. Lastly, the dietitian should provide education and information regarding outside resources to aid in ongoing compliance with the medical and nutrition prescription. The primary dietary recommendation is to remove alcohol from the diet in order to allow the liver to function more effectively while protecting it from metabolic stress. The patient should also avoid alcohol in food and medicinal products such as vinegar, sauces, and cough syrup. The dietitian should also function to correct fluid and electrolyte imbalances, nutritional deficits, such as iron deficiency anemia from chronic bloods loss in varices, ulcers, and vomiting (4). In improving the health of the liver, it can better synthesize albumin and other important serum proteins. This will help liver tissue regeneration, replenish lost plasma proteins, and improve skeletal muscle synthesis. Nutrition therapy should aim to correct metabolic syndrome, hyperglycemia, hypertension, and hypertriglyceridemia. It should also target to mend damage from fatty liver and diminished bile salt synthesis. Another important aspect is the repair of neural damage from malnutrition and malabsorption (4). Completing the Nutrition AssessmentAll sources indicate a need to first identify the severity of the disease in order to better assess the level of malnutrition and related nutrition implications. The methods which are universally used to evaluate the nutritional status and to detect the presence of malnutrition, are the Subjective Global Assessment (SGA) and anthropometric parameters (16). The SGA when compared to anthropometry shows an agreement of 77% (23). SGA is recommended by European Society for Clinical Nutrition and Metabolism (ESPEN) as a practical bedside method in assessing undernourished patients (16). SGA collects clinical information through history and physical examination. The SGA looks at variables including muscle wasting, loss of subcutaneous fat, dietary intake, functional capacity, and physical activities (23). Apart from data which are collected by the SGA questionnaire, the ESPEN guidelines recommend the use of simple anthropometric parameters also which are not affected by the presence of ascites and peripheral edema. These parameters consist of mid-arm muscle circumference (MAMC) or mid-arm circumference (MAC) and triceps skin fold thickness (TST). It is suggested that they be performed by experienced clinicians in order to avoid observer error. Diagnosis of malnutrition is established on values of MAMC and/or TST below 5th percentile in patients aged 18-74 years, or the 10th percentile in patients aged over 74 years (16). According to the Nutrition Care Manual, the first step in the nutrition assessment for cirrhosis, is physical observation. The following signs could be useful in determining the extent of liver damage: ascites, edema, muscle wasting, and jaundice. A diet history, along with a 24-hour food recall would also be useful when the registered dietitian selects recommendations for the nutrition intervention. This will give the dietitian insight into the patient’s food preferences, taste aversions, intolerances, and allergies (24). Alcoholics tend to underestimate their consumption of alcohol. Therefore, discussions with family members or close friends may help to provide a more accurate record of their intake (13). Any weight changes or alterations in appetite should be noted here as well as the use of nutritional supplements, vitamins, or minerals. Looking at the diagnostic tests, laboratory values and anthropometrics would be the next step in the nutrition assessment (24). Cirrhosis usually causes patients to have abnormal anthropometric measurements due to complications such as ascites or muscle wasting (6). Therefore when looking at indicators such as changes in weight or body mass index it is important to keep these complications in mind. Information for completing the nutrition assessment should include as many of the following criteria as possible for the most accurate evaluation:Height Weight Body Mass Index (BMI Usual Body Weight (UBW)Inquire about recent weight loss or weight gain Diet historyFood intolerances or taste aversionsPresence of anorexia, nausea, vomiting or diarrheaInput and Output (I & O)Blood pressurePresence of mild, moderate or severe fatiguePresence of leg edema or ascitesPoor wound healing Diagnostic Tests:CT scan or ultrasound of abdomenDual energy x-ray absorptiometry (DEXA) scan Liver biopsyLab workGlucose increased or decreased Glucose tolerance test Aspartate Amino Transferase (AST) Alanine Amino Transferase (ALT) International Normalized Ratio (INR) Bilirubin Serum ammonia Blood Urea Nitrogen (BUN) Albumin C-Reactive Protein (CRP)Triglycerides (TG)Cholesterol White blood cell (WBC) countSerum B12Serum Folate Plasma homocysteine Sodium (Na) Potassium (K) Hemoglobin (Hb) Hematocrit (HCT)Serum iron (Fe), Ferritin, Transferrin Uric acid (UA)GlobulinAlkaline Phosphatase (ALP or alk phos) Magnesium (Mg) Calcium (Ca) Phosphorus (Phosphate, PO4)Nutrition InterventionFor the patient who has been actively drinking alcohol, it is first essential to correct any electrolyte imbalances and to treat withdrawal symptoms (17). Malnutrition is by far considered one of the most important prognostic factors in liver cirrhosis and should alert clinicians to the same extent as the presence of other common complications of cirrhosis such as hepatic encephalopathy or ascites (16). Among cirrhotic patients, 34% are considered hypermetaboilc with resting energy expenditure 120% of the expected value. Elevated pro-inflammatory and anti-inflammatory cytokine levels point to a cytokine-driven hypermetabolism in cirrhosis (16). Those with advanced ALD may also suffer from alterations in mental status if they have hepatic encephalopathy which can contribute to poor dietary decision making. If hospitalization is required, these patients are at an even higher risk, as many diagnostic and therapeutic interventions contribute to malnutrition. Many alcoholics replace nutrients and food with alcohol. Food that is eaten tends to be richer in carbohydrates and low in protein (6). Malnourished alcoholics should consume a diet rich in carbohydrates and protein preferentially via oral or enteral routes. In hypertensive patients the Dietary Approaches to Stop Hypertension or DASH diet may be implemented as it provides adequate nutrients without excessive calories. All fasting or very low calorie diets should be avoided. Energy control is only recommended for those who are obese (24). Obesity, diabetes, and hyperinsulinemia play a role in the development of hepatic steatosis and weight loss is critical to protect liver against further damage. Four to six feedings per day, including nutritional supplements and a fluid prescription is recommended for patients with hyponatremia (24). In a Veterans Administration Cooperative study of 363 patients with alcoholic hepatitis, 100% of patients were found to have protein and/or combined protein calorie malnutrition based on anthropometric and laboratory testing (19). Due to inadequate dietary intake, maldigestion, malabsorption and/or defective metabolism there are many nutritional deficiencies often found in these patients (6). The risk of death is closely related to the degree of malnutrition (15). A randomized, controlled clinical trial compared enteral tube feedings of 2000 kcal per day with prednisolone therapy of 40 mg per day in 71 patients for 28 days. The survival rate at 28 days and at one year were similar between the two groups suggesting that nutritional support may be as effective as corticosteroids in some patients (15). RecommendationsMeals and Calories:Small frequent meals are recommended in order to prevent hypoglycemia, which can result from limited glycogen stores (4). Four to six multiple meals are recommended, containing foods rich in carbohydrates (16). In end-stage liver disease, the liver has lost some of its ability to synthesize and metabolize protein, glycogen, and very low-density lipoporoteins (VLDL). Consequently, the liver cannot regulate metabolism and therefore a continuous offering of nutrients is needed. Further nutritional support is needed in cirrhotic patients with ongoing alcohol abuse because of the risk of hypoglycemia due to the alcohol induced restriction in gluconeogenesis (16). Meals should be made make appealing to the patient in order to stimulate appetite (4). According to ESPEN, patients with liver cirrhosis should receive 30-40 kcal/kg per day (16).Carbohydrates:The plan should include sufficient carbohydrate and fat to spare protein. Overfeeding glucose can result in hyperglycemia and fatty liver and therefore is not recommended. Prescribed diets should recommend no carbohydrate intake restriction, even if the patient suffers from diabetes mellitus or demonstrates insulin resistance. 40-50% of all patients with end-stage liver disease (ESLD) suffer from insulin-resistant diabetes mellitus. When cirrhosis reaches level at which 80% of hepatocytes are dysfunctional, hypoglycemia is frequent due to high levels of insulin in the blood (4). Protein:Inadequate intake of protein is common in patients with alcoholism and cirrhosis, as mentioned above (6). Patients with liver injury both acute and chronic are in negative nitrogen balance, it is assumed that liver regeneration is delayed and muscle wasting is increased (10). Despite abnormalities in metabolism the overall nitrogen balance can be maintained with protein intake of 35-50 grams per day or with daily amounts of dietary protein (0.74 g/kg) similar to that of a healthy person (10, 6). ESPEN recommends a protein intake of 1.2-1.6 g/kg (16). The restriction of protein is often suggested in the presence of hepatic encephalopathy and hyperammonemia. However, recommendations from different medical-based sources vary. According to one source, the amount of protein intake that can be tolerated without altering mental status can vary greatly. Sometimes only a small amount of protein can be tolerated and in these cases, to minimize the breakdown of protein stores, supplementary calories from fats and carbohydrates should be given (10). According to ESPEN guidelines, when feeding protein or administering amino acids, the balance between restoring protein and precipitating hepatic encephalopathy, must be considered. The ESPEN consensus report, in 2006, concluded that low grade hepatic encephalopathy (grades I and II) is not regarded as a reason for protein restriction and malnutrition is more of a negative prognostic factor (16). According to A.S.P.E.N. Guidelines, protein should not be restricted?as a management strategy to reduce risk of developing hepatic encephalopathy. Protein?requirements for the patient with hepatic failure should be?determined in the same manner as for the general ICU patient (25).If the patient develops portal-systemic encephalopathy (PSE) and there is no evidence of other precipitating disorders such as gastrointestinal bleeding, sedative use, hypoxia, electrolyte or acid-base disturbances, volume depletion, or infections then protein can be restricted to as low as 20 g/day for only 1-2 days (17). However proteins restriction is used too often and for too long in most clinical situations and can further exacerbate catabolism (17). A daily protein intake of 1.5 g/kg of body weight is recommended even in patients with hepatic encephalopathy according to the New England Journal of Medicine (15). Branched Chain Amino Acids (BCAA):Effectiveness of using BCAA therapeutically is controversial but the majority studies indicate that BCAA can improve outcomes if given to patients with nutritional deficits. Branched-chain amino acids have a specialized role in energy metabolism. Most amino acid catabolism occurs in the liver however branched chain amino acids are catabolized mainly in the muscle, adipose, kidney and the brain. They are not only used as substrates for protein synthesis but regulate protein synthesis and consequently keep skeletal muscles intact. In liver cirrhosis the increased prevalence of hyperinsulinemia leads to an increased uptake of BCAA by skeletal muscle for use as energy. Branched-chain amino acids (BCAA) are used in attempts to reduce blood ammonia in patients with cirrhosis and intermittent hepatic encephalopathy based on the idea that BCAA stimulate muscle ammonia detoxification. Therefore, lower levels of circulating BCAA results in the destruction of skeletal muscle of these patients (16). The long-term use of BCAAs in liver cirrhosis leads to an increase in serum proteins of approximately 10% if given before bedtime (16). The ratio of the BCAAs isoleucine, leucine, valine, and lysine to aromatic amino acids, phenylalanine, tryptophan, and tyrosine is abnormally low in these patients, especially when malnourished (10). Lipids:According to the Nutrition Care Manual, for alcoholism requiring parenteral nutrition, intravenous fat intake should not exceed 2.5 grams/kg body weight per day to avoid fat overload syndrome. Fat emulsion should be used cautiously in patients with severe liver disease because of their decreased capacity to clear the infused fat (24). Fat content should include a mix of from omega-3 fish oils, omega-6 fatty acids, and medium-chain fatty acids (4). A fat restriction of less than 30% of calories, with or without medium-chain triglyceride supplements, is recommended in patients with steatorrhea (24). Increased absorption of fat can aggravate hepatic inflammation and fibrogenesis contributing to the dysfunction of the liver. Also, a diet rich in fat in combination with the impaired VLDL release can result in increased hepatic fat storage and therefore should be avoided (16). Vitamins/Minerals: The diet should include adequate amounts of vitamins C, E, and K, phosphorus, potassium, selenium, magnesium, zinc, and calcium (4). It is not generally advised to provide supplementation of vitamins and minerals in patients with ESLD but at times complications of deficiencies in various mineral and vitamins justify individualized nutritional support. Prescription of supplements in the presence of clinical symptoms of various deficiencies is indicated (16). Circulating levels of both fat-soluble and water-soluble vitamins tend to be low in many patients with ALD (6). Deficiencies in a number of vitamins and minerals is common including vitamin A, vitamin D, thiamine, folate, pyridoxine, and zinc and therefore may need to be supplemented (19). A diet low in sodium of less than 2-3 grams is generally advised in ESLD among patients with ascites and fluid retention (NCM). One of the most common complications of ESLD is osteoporosis. Patients, particularly with risk factors such as previous smoking habits, older age, and a history of fractures are candidates for supplements. The recommendation is 1200-1500 mg of calcium with 400-800 IU vitamin D (16). For vitamin A, 100,000-200,000 IU every 4 weeks is advisable (16). Supplementing vitamin K in conditions with a high risk of bleeding such as impaired prothrombin time and esophageal varices is common. Parenteral administration of 10 mg vitamin K every four weeks is recommended (16). It is common to provide B-vitamins, folic acid and vitamin K intravenously for the first few days (7). Iron intake needs to be monitored to avoid excess from the diet and/or supplements, especially if there is possibility of iron storage disease (4). Zinc is a common deficiency due to poor intake and/or increased urination (7). Alcohol dehydrogenase is made with zinc and this too may contribute to a deficiency (4). Zinc deficiency impairs would healing, immune reaction, protein metabolism and alters appetite and taste so it is important to recognize any deficiency (16). Zinc replacement of approximately 220 mg/day should be adequate. The optimal duration of vitamin and mineral support is not established but is reasonable to continue for at least six months and oral zinc for 12 months (7). Enteral and Parenteral Nutrition: Enteral nutrition via a nasogastric tube, parenteral feeding, and oral intake are used in severely ill patients with ESLD. Supplemental enteral nutrition is advisable for severely ill cirrhotic patients who are hospitalized as the method of feeding. Based on clinical trials, nutrition support results in a more rapid improvement in liver disease but does not improve survival (7). When deciding between enteral or parenteral nutrition in critically ill patients, the risk of repeated vomiting, diarrhea and aspiration during feeding through a nasogastric tube must be weighed against the complications of parenteral feeding which include fluid overload and septic complications (16). According to ESPEN guidelines, patients that cannot meet their caloric needs though oral dietary intake, despite adequate nutrition support, are candidates for supplemental enteral nutrition. Early placement of a fine-bore feeding should be considered in patients who do not eat sufficient calories (7).One clinical trial comparing nutrition support with prednisolone gave randomized patients with alcoholic hepatitis 28 days of treatments with either 2,000 calories or treatment with prednisolone and a standard hospital diet. The patients were followed for 12 months and the improvement in survival with nutrition support compared to the corticosteroid treatment was substantial, though not statistically significant due to the small study size. Survival during the first 28 days was similar between the two groups however several patients receiving corticosteroids developed infections after day 28. This began a survival advantage in the nutrition support group which was seen starting at month six and continued through to the 12 month end point (7). The majority of attending physicians do not initiate enteral feeding promptly with the idea that many patients will spontaneously start oral dietary intake when general health returns. Giving supplements with oral feedings is the standard for many hospitals (16). One study showed that oral dietary intake improved after a long hospital stay with oral nutrition support and the help of a dietitian in a 2 to 3 week period in the majority of the patients (16). However, in severely ill patients, supplemental enteral nutrition is advisable. Tube feeds, even with esophageal varices, is recommended (16). If enteral nutrition is needed, it is advised to avoid glutamine-enriched formulas which may increase ammonia levels (4). In patients with ascites the use of whole protein formulas and concentrated high energy formula is recommended. BCAA-enriched formulas are used in patients with hepatic encephalopathy arising during enteral nutrition feeds (10).In acute liver injury where the focus has been on the role of protein and amino acids on the outcome of alcoholic hepatitis, enteral and parenteral nutrition have been examined (10). In studies, patients with acute hepatitis have shown that hepatic encephalopathy can be avoided by judicious titration of dietary protein; low amounts of protein can contribute to a positive nitrogen balance, and both biochemical and symptomatic improvements have been seen (10). VI. Presentation of the patientDescription of the PatientInitials: P.W.Gender: FemaleAge: 62Race: African AmericanSocial History: Ms. W. lives alone with a son that lives nearby. Patient presents with long history of tobacco use at a pack per day for about 35 years. She also has a history of heavy alcohol use of three to six beers per day for 35 years. She denies any illegal drug use. Date of Admission: 12/06/2012Admitting Diagnosis: Metabolic Acidosis, Alcoholic CirrhosisPast Medical History: Hypertension (HTN), chronic obstructive pulmonary disease (COPD), alcoholic cirrhosis, alcoholism, primary metabolic acidosis, chronic kidney disease (CKD) stage III-IV, chronic pancreatitis, hepatic encephalopathy (no stage mentioned), anemia of chronic disease, falls, diaphragmatic hernia, gastritis, heparin-induced thrombocytopenia, pleural effusions, type II diabetes mellitus. Patient reports having falls in the yard outside of her house for the previous two weeks. According to the emergency department (ED), family and friends reported that patient has been have increased weakness and falls. She continues to consume alcoholic beverages on a daily basis despite multiple warnings in the past not to drink anymore because of her underlying cirrhosis and other areas of organ failure.She has been admitted to this hospital and others multiple times because of her alcoholism and alcohol-related complications. Per patient report, she was admitted to another hospital 5-6 days prior for a fall. There, she was treated for a laceration on her head and was given six stitches resulting from the fall. On December 6, 2012 the day of her current admission, she fell again at home and hit her head.Previous hospital admissions to this hospital: June 20, 2012 [Length of stay (LOS): 3 days] August 27, 2012 (LOS: 18 days)October 2, 2012 (LOS: 3 days)October 9, 2012 (ED)October 14, 2012 (LOS: 2 days)History with this hospital includes: chronic renal insufficiency, alcohol abuse, chronic obstructive pulmonary disease (COPD), and hypertension (HTN)ALLERGIES: Heparin, penicillin, and aspirin; no known food allergiesMedications taken at home: Lasix 40 mg daily, Pepcid 20 mg daily, Tylenol as needed for pain, Propranolol 10 g three times daily, Thiamine 100 mg dailyAdmission weight: 86 poundsAdmission height: 60 inchesPrevious Weight RecordDateWeight Lbs.Weight Kg06/21/1290 Lbs.40.9 Kg10/02/1296.8 Lbs.44 KgCurrent Medications: Medications: Propranolol, Labetalol, Lactulose, Oxepam, Omeprazole, Hydralazine, Aztreonam/Dextrose, Hydromorphone, Amlodipine Besylate, Insulin Human Lispro (HumaLOG), Dextrose, Dextrose/Water, Vitamins/Minerals: Thiamine, Folic Acid, Calcium Acetate, Sodium ChlorideLab Summary I: 12/06-12/2712/061:04 P.M.12/06 3:00 P.M.12/0712/104:30 A.M.12/1311:00 A.M.12/146:20 A.M.pH7.14Bicarbonate6Total Bilirubin0.60.60.4Direct Bilirubin0.4 H0.40.3AST343427ALT161616Alkaline Phosphatase514 H514 H413 HAmmonia119 H * Reflective of underlying hepatic encephalopathy21Total Creatine Kinase80CK-MB4.3Troponin T0.10 HTotal Protein8.15.6 LAlbumin3.4 L2.3 LGlobulin4.7 HAlbumin/Globulin Ratio0.7 LWBC31.3 HHemoglobin7.0 LHematocrit21.2 LIron78TIBC138 LTransferrin110 LFerritin930 HBeta-Hydroxyburtic Acid1.5 H (9:00 P.M.)DatepH ArterialNormal Range12/06 at 3:00 p.m.7.14 L7.35-7.45Low arterial pH or acedemia can occurs with metabolic acidosis, as well as renal failure, diarrhea, shock, and congestive heart failure (26).DateBicarbonateNormal Range12/06/12 at 3:00 p.m.6 L22-29 mmol/LThis lab value is decreased with metabolic acidosis, renal failure, and starvation (26).DateAnion GapNormal Range12/06/12 at 3:00 p.m.23 H7-15 mmol/LThis value can be increased with renal failure, ketoacidosis, or lactic acidosis (26).Lab Summary II: 12/06 through 12/27Chemistry12/6 1:04 P.M.12/6 9:00 P.M.12/7 5:15 A.M.12/8 5:37 A.M.12/9 6:04 A.M.12/104:30 p.m.12/11 4:00 a.m.Sodium140142142142143142142Potassium4.32.5 L3.83.843.3 L3.2 LChloride107106104102106106106Carbon Dioxide6 L13 L19 L23L22 L22 L22 LAnion Gap27 H22 H19 H17 H151414BUN57 H56 H53 H50 H50 H52 H55 HCreatinine4.6 H4.6 H4.0 H3.6 H3.4 H3.1 H2.8 HEst GFR A.A.12 L12 L14 L16 L17 L18 L21 LBUN/Cr ratio12.412.13.313.914.716.819.6Glucose83264 H65 L132 H157 H159 H142 HCalcium6.9 L6.3 L7.1 L8.3 L8.4 L8.2 L8.4 LPhosphorus14.1 H10.9 H9.8 H7.8 H6.4 H5.3 H4.3Magnesium1.5 L3.5 H2.7 H2.22.22.1Chemistry12/128:40 A.M.12/1311:00 A.M.12/146:20 A.M.12/159:55 A.M.12/169:00 A.M.Sodium148143145143141Potassium3.93.83.53.73.8Chloride114 H111 H112 H111 H112 HCarbon Dioxide22 L20 L19 L20 L19 LAnion Gap12.012.014.012.010.0BUN54 H52 H48 H40 H34 HCreatinine2.6 H2.4 H2.3 H2.1 H1.9 HEst GFR A.A.23 L25 L26 L29 L32 LBUN/Cr ratio20.821.720.919.017.9Glucose112 H100 H80154 H108 HCalcium9.18.7 L8.6 L8.2 L8.3 LPhosphorus4.7 H5.3 H5.0 H5.0 HMagnesium2.11.91.7 L1.7 LChemistry12/1811:07 A.M.12/198:15 A.M.12/208:40 A.M.12/2112/2312/2412/27Sodium139140141140139138136Potassium4.44.34.34.34.84.84.5Chloride110 H110 H111 H110 H109 H107 H104Carbon Dioxide21 L21 L19 L21 L19 L23 L22 LAnion Gap8.09.011.09.011.08.010.0BUN28 H242118141512Creatinine1.7 H1.7 H1.6 H1.5 H1.5 H1.5 H1.6 HEst GFR A.A.3737 L40 L43 L43 L43 L40 LBUN/Cr ratio16.514.113.112.09.310.07.5Glucose8187115 H74 L120 H96159 HCalcium8.4 L8.5 LPhosphorus4.54.4Magnesium1.5 L1.5 LTimelineAdmission to Emergency Department (ED):In the ED she was noted to be extremely acidemic and was diagnosed with alcoholic ketoacidosis for which they gave her thiamine and started her on dextrose containing IV fluids. The ED staff attempted to place an internal jugular (IJ) catheter on the patient’s left, side but were unsuccessful due to patient’s resistance. She was noted to be noncompliant and “thrashing around somewhat”. They were then able to place the catheter on the right side successfully. A chest x-ray taken in the ED showed a left pneumothorax. She was then sent to surgery where they placed a large bore thoracostomy tube for the iatrogenic pneumothorax. Patient was in increased pain because of this procedure and was given sedatives.

Chronic obstructive pulmonary diseaseVIII. Critical Comments:Evaluation of the situation: Throughout the research of this topic, it became evident that monitoring other biochemical markers would have beneficial from a nutritional standpoint. To indicate acid base balance, carbon dioxide (CO2) levels could have been tracked. This lab value is decreased with metabolic acidosis, renal failure, and starvation (26). Normal ranges are between 23-29 mmol/L. The patient started with a CO2 level at 6 mmol/L on 12/06/12 and on 12/27/12 the CO2 level had increased to 22 mmol/L which is just within the normal range and a significant improvement from admission. The patient remained with a CO2 level below 23 mmol/L up until 12/24/12. For gastrointestinal profile total bilirubin, direct bilirubin, AST, ALT, and alkaline phosphatase would have been valuable indicators of liver function. The chart below indicated the lab values for these markers on admission on 12/06/12 and again on 12/13/12.12/06 1:04 P.M.12/1311:00 A.M.Normal RangesTotal Bilirubin0.60.40.3-1.9 mg/dL (27)Direct Bilirubin0.4 H0.3< or = to 0.3 mg/dLAST3427F: 10-31 U/LALT1616F: 4-31 U/LAlkaline Phosphatase514 H413 H40-120 U/LRecommendations for improvement:Protein was initially limited due to the extremely high blood ammonia levels the patient presented with. As discussed previously, there are contradicting recommendations on limiting protein to aid in the normalizing ammonia levels. This may or may not have been necessary. A re-weight on a different scale on admission would have been beneficial to evaluate fluid weight gain and eliminate discrepancies from observer or different scales used. A usual body weight would have been useful as well as a history of recent weight loss or weight gain; within the past 30 days. The two previous weights from previous admissions were 90 lbs. on June 2, 2012 and 96.8 lbs. on October 2, 2012. The patient was a poor historian and unable to communicate diet history due to altered mental status during her admission at the hospital. Additional diet related history from family and friends could have helped to obtain more information about the patient’s diet before admission. It would have offered background regarding pattern of eating including: number of meals per day, average calorie and fluid intake amounts, intake of both macro- and micronutrients, taste aversions and preferences.Glucerna TID and a daily multivitamin we both recommended but not ordered for the patient. In addition to the multivitamin that was requested, vitamin D should have been added as osteopenia noted in bones on a CR chest portable on 12/10/12. In addition, zinc and vitamin A are recommended for chronic alcohol abusers as they are often depleted.Validation of Treatment Received:On admission, the patient was given thiamine immediately in the ED along with dextrose containing IV fluids. This helped to replenish her of electrolytes, fluid, and thiamine. In the ICU the patient was given IV bicarbonate fluids for alcoholic ketoacidosis to improve her acidemic state. Also, in the ICU, a KEO feeding tube was placed for administering medications. This was a good choice for a feeding tube versus an oral gastric tube which is often placed for short-term use in hospitals as it allows for medications and feeds to be given as well as suction if needed. The KEO feeding tube is small bore so usually better tolerated by patients and is intended for more long-term use which would allow for on-going enteral feeds if needed. The placement of the KEO feeding tube was verified with CR chest portable which is viable as sometimes the feeding tubes are misplaced and can even end up in the patient’s lung. It is important to verify that the feed is going into stomach.Speech was consulted and followed the patient throughout her stay; SLP is an important part of the care team especially when dysphagia and altered mental status are present. It is important to ensure that the patient is being fed appropriately and without harm. This can eliminate additional illness from infections such as pneumonia resulting from aspiration of food or fluid into the lungs. The prescribed diets were discussed with speech and necessary advances were initiated when medically appropriate. IX. SummaryDue to the complex nature of the disease and its involvement with virtually every system in the body, ALD is complicated to both diagnose and treat effectively. It truly takes the effort and collaboration of a number of healthcare professionals to insure that the patient is receiving the most accurate and effective care available. As with many other on-going health problems, recovery takes commitment and effort on the part of the patient as well. Unfortunately without the necessary behavior and lifestyle changes to stop consuming alcohol, the disease will only progress. Once the disease has progressed to the third and final stage of decompensated cirrhosis, liver transplant is the only available treatment. Without the cessation of drinking, the possibility of receiving a donor liver is not likely. Nutrition plays an integral role in the treatment of ALD. Evaluation of the degree to which the disease has progressed is the first step in the nutrition assessment. From here, the dietitian can determine the level of malnutrition present and calculate recommended amounts of macro and micronutrients to replenish deficits and promote healing. In this case study, the patient suffered from ALD as well as many of the complications often seen with the disease including hepatic encephalopathy. Through medical and nutritional interventions the patient became stable and suitable discharge after 22-day stay at the hospital. The patient arrived to the hospital and was made NPO status. She was then started on an enteral feed of Nepro 1.8 by way of a KEO feeding tube. After speech consulted with the patient, she was advanced to a dysphagia 2 diet and then to a mechanical soft diet. The patient was given thiamine, folic acid and calcium acetate throughout her stay at the hospital. Additional vitamins and minerals were recommended in the form of a daily multivitamin but this along with the recommendation of Glucerna TID was not carried out in the physician’s order. After the patient had last been assessed on December 24, 2012, she was discharged on December 28, 2012. Home care services with physical therapy were arranged. She was sent home with medications and outpatient follow-up and referrals. The patient was hemodynamically and clinically stable at time of discharge according to the hospital’s discharge summary. The total length of stay at the hospital was 22 days. To date, the patient has had no new admissions to this hospital since discharge. IX. MEDICAL TERMINOLOGY GLOSSARY Apoptosis: programmed cell death; deletion of individual cells by fragmentation into membrane-bound particles, which are phagocytized by other cells.Ascites: a distended abdomen due to pathological fluid in the peritoneal cavity.Asterixis: involuntary jerking movements, especially in the hands, best elicited by having the patient extend the upper limb, dorsiflex the wrists, and spread the fingers; results from lapses of sustained posture; seen primarily with various metabolic and toxic encephalopathies, especially hepatic encephalopathy. Alternate names: flapping tremorClubbing of fingers: occurs most often in people who have heart or lung disorders that decrease the amount of oxygen in their blood. This causes the fingertips and fingernails to spread out and become rounder.Colloidal osmotic pressure: (COP) important determinant of the appearance of edema; osmotic pressure exerted by the tissues in the bodyCyanosis: A dark bluish or purplish discoloration of the skin and mucous membrane due to deficient oxygenation of the blood, evident when reduced hemoglobin in the blood exceeds 5 g/100 mL.Cytokine: Any of several nonantibody proteins, such as lymphokines, that are released by a cell population on contact with a specific antigen and act as intercellular mediators, as in the generation of an immune response.Edema: fluid buildup in the extremitiesElectroencephologram (EEG): A painless procedure that uses small, flat metal discs (electrodes) attached to your scalp to detect electrical activity in your brain. Your brain cells communicate via electrical impulses and are active all the time, even when you're asleep. This activity shows up as wavy lines on an EEG recording.Encephalopathy: Any disorder of the brain. Alternate names: cerebropathia, cerebropathy, cerebropathy, encephalopathia, encephalosisEnterohepatic circulation: circulation of substances such as bile salts that are absorbed from the intestine and carried to the liver, where they are secreted into the bile and again enter the intestine.Hepatic encephalopathy: A potentially fatal brain disorder that results when prolonged liver dysfunction caused by excessive alcohol consumption leads to the accumulation of toxic substances in the brain.Hepatorenal syndrome: the occurrence of acute renal failure in people with disease of the liver or biliary tract, apparently due to decreased renal blood flow and conditions that damage both organs, such as carbon tetrachloride poisoning and leptospirosis.Iatrogenic pneumothroax: pneumothorax caused by a medical procedure, most often central venous catheter insertion, thoracentesis, or transbronchial and transthoracic lung biopsy.Jaundice: yellow color in the skin, mucus membranes, or eyesKEO feed tube: small bore nasogastric feeding tubeKlebsiella: a group of bacteria normally living in the intestinal tract and frequently the cause of nosocomial infections (infections acquired in the hospital). Named for Dr. Klebs.Macrophages: type of white blood that takes in (ingests) foreign material. Macrophages are key players in the immune response to foreign invaders of the body, such as infectious microorganisms.Melena: bloody, dark black, or tary bowel movementsMyofibroblasts: spindle-shaped cells with characteristic contractile and structures that contribute to the wound healing process. They occur in granulation tissue and also in pathological processes such as fibrosis.?Neoantigen: antigenic proteins formed by metabolic pathways (drug metabolism).Otomastoiditis: is the result of an infection that extends to the air cells of the skull behind the earOsteopenic: showing signs of osteopenia which is a condition where bone mineral density is lower than normal.Parenchyma: he distinguishing or specific cells of a gland or organ, contained in and supported by the connective tissue framework, or stroma. The endoplasm of a protozoan cell. In the lung, consists of the gas-exchanging portion, excluding the radiographically visible blood vessels and bronchi.Pleural effusions: outpouring of fluid between the two layers of the pleural membranes that cover the lungs. The term "effusion" comes from the Latin "effusio" meaning a pouring out. A pleural effusion is thus, literally, a pouring out of fluid into the pleural space. By comparison, a pericardial effusion is an outpouring of fluid within the fibrous sac (the pericardium) that surrounds the heart.Pneumothroax: free air in the chest outside the lung. Pneumothorax can occur spontaneously ("out of the blue"), follow a fractured rib, occur in the wake of chest surgery, or be deliberately induced in order to collapse the lung.Portal hypertension: abnormally high blood pressure in the portal vein (the large vein that brings blood from the intestine to the liver) and its branches. Sinusoid: Resembling a sinus. Sinusoidal capillary; a thin-walled terminal blood vessel having an irregular and larger caliber than an ordinary capillary; its endothelial cells have large gaps and the basal lamina is either discontinuous or absent.Stellate cell: cell that is vital to hepatocellular function and the liver's response to injury. Indeed, the paradigm of stellate cell activation into contractile myofibroblasts as the major pathway in hepatic fibrogenesis associated with liver injuryThoracostomy tube: a tube placed through the chest wall that drains the pleural space.Varices (gastric or esophageal): extremely dilated sub-mucosal veins result of portal hypertension; they are superficial and liable to ulceration and massive bleeding.Wernicke’s encephalopathy and Korsakoff psychosis: Different conditions that are both due to brain damage caused by a lack of vitamin B1 (thiamine).Korsakoff syndrome, or Korsakoff psychosis, tends to develop as Wernicke's symptoms go away. Wernicke's encephalopathy causes brain damage in lower parts of the brain called the thalamus and hypothalamus. Korsakoff psychosis results from damage to areas of the brain involved with memory.X.
