|6 |BRIEF RESUME OF THE INTENDED WORK: |
| |6.1 Need for the study |
| |Alcohol-dependence is a disabling addictive disorder, characterized by compulsive and uncontrolled consumption of alcohol despite |
| |its negative effects on the drinker's health, relationships, and social standing.1 High alcohol consumptions are correlated with an|
| |increased risk of developing cardiovascular disease, malabsorption, chronic pancreatitis, alcoholic liver disease, cancer, and |
| |damage to the central nervous system and peripheral nervous system . The most common cause of illness and death from liver disease |
| |is long-term alcohol consumption. Liver is the primary site of alcohol metabolism. Injury to the liver comes not only from ethanol, |
| |but its dangerous products of metabolism like acetaldehyde and free radicals.1,2 Many molecular and metabolic phenomena have been |
| |implicated in the pathogenesis of alcohol-related diseases. Alcohol promotes the formation of free radicals and interferes with |
| |antioxidant defense mechanisms of the body. Toxic compounds like acetaldehyde generated during alcohol metabolism, form adducts with|
| |DNA and proteins. 1,2 |
| | |
| |Changes in plasma protein levels and status of acute phase protein pattern are keenly studied by researchers worldwide. Serum total |
| |proteins can be affected in heavy drinkers. A common feature of chronic alcoholic liver disease is progressive hypoalbuminaemia.2 |
| |C-reactive protein (CRP) has been found to be an accurate marker of alcoholic hepatitis. It is also considered a marker of future |
| |cardiovascular death.2 Studies have shown conflicting results about the serum copper and ceruloplasmin levels in alcoholics. 3 |
| | |
| |There are still some gaps in our knowledge about serum protein patterns, the role of C-reactive protein and ceruloplasmin in the |
| |pathophysiology of alcohol-related disorders. This study has been undertaken to throw more light on the relevance and importance of |
| |these biochemical parameters in alcohol-dependent patients. |
| | |
| |6.2 Review of Literature |
| |Alcohol-dependence syndrome, according to ICD-10 is diagnosed if three or more of the six criteria are met for at least a period of |
| |one month during last 12 months. These criteria are craving for alcohol, impaired capacity to control alcohol taking behaviour, |
| |physiological withdrawal state, tolerance, preoccupation with alcohol use and persistent alcohol use despite clear evidence of |
| |harmful consequences. A number of self-report screening tests have been developed to identify alcoholics as well as persons at risk.|
| |One of the most widely used alcohol screening test is CAGE (C-cut down, A-annoyed, G-guilty, E-eye opener), which contains only four|
| |questions. Reliability and validity studies of this test have been conducted in diverse samples with generally acceptable levels of |
| |sensitivity. The Alcohol Use Disorders Identification Test (AUDIT) is a 10-item screening instrument that may be used for recording |
| |comprehensive and sequential alcohol use. It has been shown to be sensitive and specific in discriminating alcoholics from |
| |nonalcoholics. The AUDIT total score increases with the severity of alcohol-dependence and related problems.4 |
| | |
| |Acute as well chronic ethanol consumption has been shown to inhibit hepatic protein synthesis and secretion. Studies have found |
| |progressive hypoalbuminemia in patients with chronic alcoholic liver disease. In spite of a rise in mRNA level of albumin in liver |
| |in response to alcohol intoxication, the decrease in serum albumin level is attributed to nutritional status of the subjects. |
| |Albumin is a potential subject of formation of adduct by acetaldehyde, an alcohol metabolite. This albumin or other protein adducts |
| |can stimulate the formation of immunoglobulins, thus causing a rise in serum globulin level.1,2,5 The appearance of |
| |carbohydrate-deficient isoforms of glycoproteins such as transferrin has been proved as a marker of chronic alcohol consumption. 2 |
| | |
| |Majority of the plasma glycoproteins are acute phase proteins. It has been reported that chronic alcohol consumption stimulates the |
| |hepatic synthesis of acute phase proteins. Prominent among the acute phase proteins is CRP. Moderate alcohol intake is associated |
| |with decreased CRP and leukocyte count, but there is an inverse association with heavy drinking.6 CRP has also been found to be an |
| |accurate marker of alcoholic hepatitis. |
| | |
| |Altered serum levels of copper and ceruloplasmin have been reported by previous studies but, there are contradicting findings with |
| |some studies reporting lower levels while others reporting higher levels in alcoholics.3 |
| |6.3 Objectives of the study |
| |To estimate the serum levels of total proteins, albumin, C-reactive protein and serum ceruloplasmin in alcohol-dependent males in |
| |comparison to healthy controls. |
| |To study the serum protein electrophoresis pattern in alcohol- dependent males in comparison to healthy controls. |
|7. |Material and methods: |
| |7.1 Source of data |
| |Subjects will be Alcohol–dependent male patients admitted to the de-addiction centre of Father Muller Medical College Hospital. |
| |Healthy male volunteers will be the controls. |
| |Data are collected through questionnaires and assays of serum proteins and protein pattern. |
| |7.2 Method of collection of data ( including sampling procedure, if any) |
| |Type of study |
| |Cross sectional, case control study |
| |Method of collection of data |
| |30 alcohol-dependent male in-patients will be recruited randomly for the study over a period of 1 year. Psychiatric diagnosis, |
| |medical history, relevant clinical findings and other investigations will be obtained from the clinical case files. Sociodemographic|
| |data will be collected using a proforma designed for the study. Alcohol consumption related data will be obtained by using AUDIT |
| |which is a screening questionnaire for detailed alcohol use history. |
| |Controls include thirty age-matched normal, apparently healthy males. CAGE questionnaire will be administered to volunteers to |
| |exclude those with problem drinking. |
| |Inclusion criteria for cases: |
| |1. Age: 18-65 years. |
| |2. Alcohol dependence syndrome - diagnosed by a psychiatrist. |
| | |
| |Exclusion criteria: |
| |1. Patients in delirium |
| |2. Patients with systemic illnesses |
| |3. Patients with other substance abuse/dependence including nicotine. |
| |Methods : |
| |About 5 ml venous blood will be collected and in serum under aseptic precautions and following assays will be done : |
| |Total proteins: estimated by biuret method, 7 |
| |Albumin : estimated by bromocresol green dye binding method, 7 |
| |C-reactive protein (CRP): estimated by turbidometric method, 8 |
| |Ceruloplasmin: Assayed using p-phenylene diamine dihydrochloride as the substrate.9 |
| |Serum protein electrophoresis: carried out using agarose gel and horizontal gel electrophoresis equipment.7 |
| |Plan for data analysis |
| |Collected data will be analysed by |
| |- unpaired t test |
| |- Karl Pearson correlation co efficient |
| | |
| | |
| | |
| | |
| |7.3 Does the study require any investigations or interventions to be conducted on patients or other humans or animals? If so, please|
| |describe briefly. |
| |Yes. With aseptic precautions, about 5ml of venous blood will be collected from inpatients with alcoholic-dependence syndrome and |
| |controls after taking written informed consent. |
| | |
| |7.4 Has ethical clearance been obtained from your institution in case of 7.3 |
| |Yes. |
