Purpose - NPAIHB
Guidelines for Screening, Management and pre-treatment work-up for Hepatitis C virus (hCv) Within IHS, Tribal and urban Indian Healthcare FacilitiesThis template is a sample policy for HCV screening, follow up, and treatment. This is a template, and as such it is not comprehensive and does not mandate any clinical activities. It does provide a sample policy for I/T/U facilities to provide a range of HCV services at the primary care level, and should be adapted as needed to reflect local conditions and priorities. An HCV policy can be instrumental for clinical staff to understand HCV patient needs, clinical algorithms, and best practices. American Indians/Alaska Natives have the highest rate of mortality from HCV all I/T/U facilities are encouraged to provide early detection and linkage to care. For further questions or support, contact Dr. Jonathan Iralu, Chief Clinical Consultant, Infectious Disease, jonathan.iralu@PurposeTo expand screening, management and pre-treatment care for HCV infection. backgroundIn the United States, an estimated 3 million persons are chronically infected with HCV.

ADDIN EN.CITE.DATA [5] Clinicians should confirm patients testing positive for HCV antibodies for HCV infection. After confirming HCV infection, clinicians should continue with a a pre-treatment checklist and in consultation with a specialist when needed, start patients on appropriate treatment regimens and continuously monitor patients’ progress until they reach a cure.A number of individuals in the IHS patient population have been diagnosed with HCV, but have never been linked to treatment. Over a 30-year period, an estimated 85% of patients with acute HCV infection will go on to develop chronic HCV infection, 34% of patients will go on to develop cirrhosis, and 9% of patients will go on to develop hepatocellular carcinoma. Currently, effective treatments for HCV can reduce HCV viral loads to virtually non-detectable levels without the need for pegylated interferon, a medication associated with a longer duration of treatment and more severe side effects than other treatments. To prevent progression to cirrhosis, hepatocellular carcinoma, and liver failure, clinicians should stage HCV-infected patients, prioritizing patients with advanced liver fibrosis stages to receive immediate treatment. Clinicians should monitor patients with early liver fibrosis stages and also start these patients on treatment as it becomes available.DefinitionsHepatitis C Virus (HCV): International Classification of Disease (ICD)-9: 070.41, 070.44, 070.51, 070.54, 070.70 through 070.71; ICD-10: B17.10, B17.11, B18.2, B19.20, B19.21 and HCV screening as Correct Procedural Terminology (CPT) 86803, or as per local Logical Observation Identifiers Names and Codes (LOINC) or laboratory taxonomies for hepatitis antibody testing.Sustained Virologic Response (SVR): Hepatitis C virus remains undetectable in blood following completion of treatment. SVR is the goal of HCV treatment. SVR, the surrogate marker for HCV cure after completion of therapy is defined as undetectable HCV RNA using a highly sensitive assay 12 weeks following the end of treatment.High-Risk Patient: A patient not currently diagnosed with HCV, but who has participated in certain behaviors, possesses certain medical conditions, and/or falls into certain categories that increase his or her risk of HCV infection.

Each recommendation is referenced to an online resource.HCV SCREENINGScreen for HCV-infected patientsClinicians should screen the following categories of patients for HCV antibodies: Patients born from 1945 to 1965 (one-time screening), which national data has shown constitutes 75% of reported cases [5]. Additional age ranges may be included in this screening where local data suggests an elevated HCV burden may exist. Patients determined as high-risk (routine screening unless otherwise noted):Vietnam Veterans serving between 1964 and 1975HIV-positive individuals (at least annual screening for HIV-positive men who have sex with men)Patients who have ever injected illicit drugs, including those who injected drugs just once or a few times many years ago (at least annual screening for current injection drug users)Patients with certain medical conditions, such as those with hemophilia with receipt of clotting factor concentrates before 1987, those with a current or history of long-term hemodialysis, and those with persistently abnormal alanine aminotransferase levelsPatients who received a transfusion or organ transplant before July 1992 or received blood from a donor who later tested HCV-positivePatients with recognized exposure, for example, health care workers exposed after needle sticks, sharps or mucosal exposures to HCV-positive blood, and children born to HCV-positive mothersTest for HCV antibodiesClinicians should screen for HCV in patients identified as belonging to the above categories using immunoassays, such as the OraQuick HCV Rapid Antibody Test (OraSure Technologies) or an FDA-approved, laboratory-conducted HCV antibody assay [7]. The best assay for this purpose is a HCV antibody test with reflex ribonucleic (RNA) confirmation.Test for HCV RNA and determine viral loadClinicians should perform Nucleic Acid Testing (NAT) for patients with reactive immunoassays (and for patients with non-reactive immunoassays if patients are immunocompromised or have been recently exposed to HCV).Clinicians should consider a reactive immunoassay and a negative NAT result to signify a false positive serology or the patient having cleared infection. Clinicians should link patients with a positive NAT result to care; Clinicians should not repeat NAT for patients with a negative NAT result unless patients have been exposed to HCV within the past 6 months, patients present with clinical evidence of disease, or specimens have been mishandled or improperly stored.Clinicians should determine a quantitative HCV RNA viral load to provide baseline markers to determine treatment progress.Patients who are positive for HCV+ Ab but HCV RNA negative may have spontaneously cleared the virus. This occurs in an estimated 15%-25% of HCV exposed individuals. Such patients need no further follow up for HCV (except counseling on risk behaviors as appropriate) and will test positive for HCV Ab+ during their lifetimes. Consequently, any subsequent testing for HCV in this population subset should immediately include RNA testing.Perform laboratory evaluationUpon confirming chronic HCV infection, clinicians should perform the following set of additional laboratory tests (where tests are available):General laboratory evaluation, including complete blood count, platelet count, thyroid function tests, and renal function testsTests to determine hepatic inflammation, such as alanine aminotransferase or aspartate aminotransferaseTests to determine hepatobiliary disease, such as bilirubin and alkaline phosphataseTests to determine hepatic function, such as serum albumin and prothrombin timeAssays to detect significant co-infections, such as hepatitis A antibody, hepatitis B surface antigen, hepatitis B surface antibody, hepatitis B core antibody, HIV antibodyPerform complete patient history and examinationUpon confirming chronic HCV infection, clinicians should perform complete patient medical histories and physical examinations. Clinicians should determine patients’ risk factors for acquiring HCV infection, psychiatric history, significant comorbidities, co-infection with other viruses, stigmata of chronic liver disease, clinical manifestations attributable to HCV infection, history of prior treatment, and previous assessment of liver fibrosis.

Psychiatric issues are generally not contraindications for HCV treatment. Upon diagnosing psychiatric issues, clinicians should link patients to psychiatric treatment, as appropriate.Significant comorbiditiesClinicians should determine secondary causes of liver disease, such as non-alcoholic fatty liver disease, alcoholic hepatitis, or autoimmune hepatitis. Clinicians should also advise obese patients to lose weight prior to beginning HCV treatment, and cessation of alcohol and tobacco use.Co-infection with other virusesClinicians should screen HCV-infected patients for hepatitis A virus, hepatitis B virus, and human immunodeficiency virus (HIV). If patient is not immune to hepatitis A or B, consider vaccination.Stigmata of chronic liver diseaseClinicians may consider the presence of the following physical signs and symptoms (in decreasing order of the likelihood ratio of cirrhosis) as indicators of cirrhosis: caput medusae/dilated abdominal wall vessels, loss of body/pubic hair, hepatic encephalopathy, gynecomastia, ascites, spider angiomata, palmar erythema, jaundice and scleral icterus, and liver stiffness.Clinical manifestationsClinicians should determine extrahepatic clinical manifestations of chronic HCV infection, such as arthralgias, neuropathy, nephropathy, glomerulonephritis, livedo reticularis, lichen planus, and cold agglutinin disease.History of prior treatmentClinicians should determine if patients have previously undergone HCV treatment. If patients have failed to obtain sustained virologic response with previous HCV treatment, clinicians should determine the following with regard to previous HCV treatment: medications, duration, timing, patient’s degree of adherence, adverse effects, and when possible, viral kinetics and outcome.Previous assessment of liver fibrosisClinicians should determine whether patients have previously had a liver biopsy. For patients who have had a liver biopsy, clinicians should record the date of the biopsy, the sample size, the fibrosis scoring system, and the fibrosis score. Clinicians should also note any previously performed non-invasive tests for determining liver fibrosis scores.Stage HCV Liver FibrosisAlthough the gold standard to stage hepatic fibrosis is by performing a liver biopsy with histologic analysis, noninvasive testing with ultrasound transient elastography (FibroScanTM) or blood test staging methods are widely used, acceptable, and more feasible. These methods include two of the following non-invasive tests for indirect markers of cirrhosis: Aspartate Aminotransferase-to-Platelet Ratio Index (APRI), Fibrosis-4 (FIB-4), and FibroSure. When using non-invasive tests, if both tests determine the fibrosis score as F1, treatment is optional if patients have no contraindications; if both tests determine the fibrosis score as F2 or above, clinicians should begin patients on antiviral therapy if patient has no contraindications. If tests determine disparate results, clinicians should consider following up with a liver biopsy or FibroScan.

A genotype test will also be needed to determine the recommended course of treatment.? Clinicians should prioritize patients with advanced or compensated cirrhosis (F3 and F4 fibrosis scores, respectively), patients with severe or extrahepatic HCV, and liver transplant recipients to receive immediate treatment. [10-13]Patients should also be vaccinated for Hepatitis A and B, if immunity is not detected.While treatment may depend on a variety of factors, linkage to care for patients with chronic HCV infection should be as timely as possible.? IHS sites should determine what is the best course of action for linkage to care that are the most feasible for their patients, based on the overall case load and acuity.? Linkage to care can entail multiple options such as external referrals to specialists, or treatment within the facility with on-site (visiting specialist clinic) or remote specialist support (e.g. telehealth) for primary care clinician-led HCV treatment programs.All HCV-confirmed patients should be counseled in regards to reducing the risk for spread of HCV infection, the risks for sexual partners, and the avoidance of hepatotoxic substances (OTC and prescription drugs, alcohol, and supplement use).When appropriate, clinicians should counsel patients on weight loss and diet. Clinicians should advise patients about all restrictions and/or considerations before patients begin treatment. A pre-treatment checklist is in the appendix of this policy. Approach to Monitoring After Receiving HCV Therapy: The approach to monitoring patients following completion of a course of HCV therapy depends entirely on the patient's response to therapy. Three main scenarios exist: (a) the patient achieved an SVR, (b) the patient completed therapy but did not achieve an SVR, or (c) the patient had an inadequate treatment course because of adherence problems, intolerance, or laboratory toxicity necessitating premature discontinuation of the treatment regimen.Monitoring Patients who Achieved an SVR: Patients who have an undetectable HCV RNA at week 12 (or later) after completing HCV therapy are considered to have achieved an SVR. In a review by Welker of 44 studies involving more than 4,228 patients who achieved an SVR with an interferon-based regimen, 97% of patients maintained the SVR during the long-term follow-up period. Some experts will obtain an HCV RNA level 24 weeks after completing treatment in selected patients. In a more recent review by Manns, more than 99.2% of 1002 patients who achieved an SVR12 with interferon- or peginterferon-based therapy maintained undetectable HCV RNA levels for 5 years. Comparable data on the long-term durability of treatment response with all-oral DAA therapy is not yet available, but it is generally thought that SVR12 responses will represent sustained HCV clearance similar to that seen with interferon-based therapy. All patients who achieve an SVR should clearly understand they are not immune to HCV and can become reinfected with HCV. The AASLD/IDSA Guidance stratifies the follow-up for persons who achieve an SVR based on the degree of hepatic fibrosis and the risk of developing reinfection.Patients with without advanced fibrosis (Metavir stage F0-F2): These patients do not need special monitoring or follow-up specifically for HCV or liver care. This recommendation is based on data that show patients with SVR following HCV treatment generally do not have further progression of HCV-related liver fibrosis.Patients with Advanced Fibrosis (Metavir stage F3-F4): Although fibrosis may improve in these patients, they are considered to have persistent risk, albeit lower than before achieving an SVR, for developing hepatocellular carcinoma. Accordingly, these patients should have surveillance for hepatocellular carcinoma (HCC) with hepatic ultrasound every 6 months. In addition, patients with cirrhosis (F4 fibrosis) should have a baseline upper endoscopy to screen for varices, unless this has previously been done. Patients identified with varices should receive appropriate management and follow-up.Patients with Ongoing Risk of HCV Reinfection: Regardless of the degree of hepatic fibrosis, all patients with ongoing risk for acquiring HCV should have periodic assessment for HCV reinfection and counseling on prevention of reinfection. Obtaining HCV antibody does not provide useful information in these individuals with known prior HCV infection since they are highly likely to remain antibody positive. Thus, reassessment should consist of a quantitative HCV RNA level. In addition, for these patients, any flare in liver enzyme tests should prompt evaluation for reinfection with a quantitative HCV RNA level.Patients with Persistently Abnormal Liver Tests: Any patient that develops persistently elevated liver tests should undergo evaluation for possible other causes of liver disease, such as alcohol use, iron overload, or fatty liver disease.Monitoring for Patients who do not Achieve SVR: The AASLD/IDSA guidance recommends the following for patients who did not achieve an SVR with HCV therapy. All Patients: For all patients who did not achieve an SVR, follow-up laboratory testing should occur every 6 to 12 months with a hepatic function panel, complete blood count, and international normalized ratio. In addition, these patients should have periodic reevaluation for retreatment, especially as new options become available. It is important these patients receive counseling for alcohol abstinence (or safe use) and avoidance of hepatotoxic medications.Patients with Advanced Fibrosis (Metavir Stage F3-F4): These patients should have surveillance for hepatocellular carcinoma with hepatic ultrasound every 6 months. In addition, patients with cirrhosis (F4 fibrosis) should have a baseline upper endoscopy to screen for varices, unless this has previously been done. Patients identified with varices should receive appropriate management and follow-up.Reporting Health providers in FORMTEXT ????? are required to report cases of chlamydia, gonorrhea, syphilis, genital herpes and chancroid to the local health department.

For persons who are immunocompromised, testing for HCV RNA can be considered. ? To differentiate past, resolved HCV infection from biologic false positivity for HCV antibody, testing with another HCV antibody assay can be considered. Repeat HCV RNA testing if the person tested is suspected to have had HCV exposure within the past 6 months or has clinical evidence of HCV disease, or if there is concern regarding the handling or storage of the test specimen.Source: CDC.
