When indicated, anti-HBV prophylaxis should be initiated as soon as possible before or, at the latest, simultaneously with the onset of immunosuppressive therapy. Although TAF is not U.S. Food and Drug Administration approved for use in patients with decompensated cirrhosis, it is a reasonable option for patients needing tenofovir therapy (e.g., patients who are lamivudine resistant) who have or are at risk for bone or renal diseases that might be complicated by the use of TDF. Anti-HDV screening is recommended in HIV-positive persons, persons who inject drugs, men who have sex with men, those at risk for sexually transmitted diseases, and immigrants from areas of high HDV endemicity. The criteria for HBV reactivation171-178 include the following: (1) a rise in HBV DNA compared to baseline (or an absolute level of HBV DNA when a baseline is unavailable) and (2) reverse seroconversion (seroreversion) from HBsAg negative to HBsAg positive for HBsAg-negative and anti-HBc–positive patients. DISEASE REPORTING 1.1 Purpose of Reporting and Surveillance 1. HBIG is not required for prophylaxis.260 Though lamivudine has been used widely because of the lower rate of replication risk,260 use of antivirals such as entecavir, TDF, or TAF would be predicted to have the lowest risk for resistance with long-term use. Indicates those who should receive hepatitis B vaccine, if seronegative. Since achieving the endpoint of HBsAg loss is unlikely in most CHB patients, the goals of therapy need to be based on obtaining sustained viral suppression either with long-term nucleo (t)side analogue (NA) therapy or short-term immunomodulators (pegylated interferon) which may result in ‘immune control’. A hepatitis flare is reasonably defined as an ALT increase to ≥3 times the baseline level and >100 U/L. people with fulminant liver failure); one trial included only people with severe acute HBV, but it did not state whether any of the people also had fulminant HBV infection; three trials excluded fulminant HBV infection; and two trials did not report the severity of acute HBV infection. To determine whether cases may … Treatment with antivirals does not eliminate the risk of HCC, and surveillance for HCC should continue in persons who are at risk. In 2018, 3,322 cases of acute hepatitis B were reported; however, because of low case detection and reporting, the Centers for Disease Control and Prevention (CDC) estimates that there were 21,600 acute hepatitis B infections. Thus, there are insufficient data to recommend use of TAF in children 12 years of age and older. Hepatitis B virus (HBV) is the leading cause of chronic liver disease worldwide. The AASLD suggests that adults with compensated cirrhosis and low-level viremia (<2,000 IU/mL) be treated with antiviral therapy to reduce the risk of decompensation, regardless of ALT level. Supportive treatment recommendations are the same for acute hepatitis B as for acute hepatitis A. Lamivudine, adefovir dipivoxil, and other antiviral therapies appear to have a positive … However, extra care is necessary to evaluate the mother and to ensure that the infant receives HBIG and HBV vaccine within 12 hours of birth. DISEASE REPORTING 1.1 Purpose of Reporting and Surveillance 1. 5 SAMJ infants and children under the age of 5 years, and <5% of adults will develop chronic hepatitis B infection. An upper limit of normal for ALT of 35 U/L for males and 25 U/L for females is recommended to guide management decisions. Treatment discontinuation in persons with cirrhosis is not recommended owing to the potential for decompensation and death, although data are limited. The AASLD recommends against the use of antiviral therapy in HBeAg-positive children (ages 2 to <18 years) with persistently normal ALT, regardless of HBV-DNA level. These patients should be monitored with ALT determination every 3 months during the first year to verify that they are truly in the “inactive phase” and then every 6-12 months.100, 125 If the ALT level becomes elevated, monitoring should occur more frequently. HBsAg-negative, anti-HBc–positive patients with rheumatological conditions receiving biological therapies,198-200 inflammatory bowel disease treated with TNF inhibitors,201 and patients with psoriasis treated with biologicals or conventional immunosuppressive therapies202 were successfully monitored without anti-HBV prophylaxis. Patients who are already receiving effective ARVT that does not include a drug with antiviral activity against HBV should have treatment changed to include TDF or TAF with emtricitabine or lamivudine. The guideline for HCC recommends surveillance of persons at high risk of HCC with US every 6 months. Serum HBV DNA varies from undetectable to several billion IU/mL. 1-5 Globally and in North America, approximately 10% of patients with HIV … Antiviral therapy is not recommended for persons without cirrhosis who are HBeAg negative with normal ALT activity and low-level viremia (<2,000 U/mL; “inactive chronic hepatitis B”). (Strong recommendation, very low level of evidence). Follow up. Developed by the AAP (American Academy of Pediatrics) Committee on Infectious Diseases in conjunction with the CDC (Centers for disease control), the FDA (Food and drug administration), and other leading institutions with contributions from ... Patients with chronic hepatitis B need to … HBsAg quantitation is not recommended for the routine testing or follow-up of patients with CHB. This book provides a practical approach for physicians to apply on patients with apparent liver function abnormalities. For those who are nonresponders to the initial vaccination series, a second series of 0-, 1-, and 6-month vaccination is recommended.84 For those who are immunocompromised, including those with HIV, on dialysis, or with cirrhosis, use of a double dose of vaccine has been shown to increase the percentage of patients achieving protective antibody titers, the level of anti-HBs achieved, and/or the duration of protection.85-87 HBV vaccine with or without HBIG is also recommended for postexposure immunoprophylaxis of unimmunized individuals who have percutaneous, mucosal, or sexual exposure to HBsAg-positive or HBsAg-unknown sources. … Indicates those who should receive hepatitis B vaccine, if seronegative. Long-term follow-up should be continued to assess need for future therapy. 6B. This can happen through sexual contact; sharing needles, syringes, or other drug-injection equipment; or from mother to baby at birth. Consider TAF or entecavir in patients with or at risk for renal dysfunction or bone disease. J Infect Dis. Thus, all persons who are positive for anti-HBc (with or without anti-HBs) should be considered potentially at risk for HBV reactivation in this setting. There is significant uncertainty in the results and further RCTs are required. Hepatitis B is a serious disease caused by a virus that attacks the liver. Hepatitis has a broad spectrum of presentations that range from a complete lack of symptoms to severe liver failure. Acute hepatitis is a term used to describe a wide variety of conditions characterized by acute inflammation of the hepatic parenchyma or injury to hepatocytes resulting in elevated liver function indices. In HBeAg-positive patients, the mean decline in the estimated glomerular filtration rate was −0.6 mL/min for TAF patients, whereas the decline was −5.4 mL/min in TDF patients (P < .0001). All transplant recipients of extrahepatic organs should be evaluated for HBV infection and immunity with HBsAg, anti-HBc, and anti-HBs. February 2021 . Additionally, studies on the use of TDF for prevention of mother-to-child transmission led to TDF being elevated to the level of preferred therapy in this setting (section 1C of Screening, Counseling, and Prevention of Hepatitis B). However, occasional deaths from hepatitis A have occurred due to liver failure, and some people have required a liver transplant for acute hepatitis A infection. Safety of complete and sustained prophylaxis withdrawal in patients liver-transplanted for HBV-related cirrhosis at low risk of HBV recurrence, Hepatitis B virus infection and immunosuppressive therapy in patients with inflammatory bowel disease, Successful withdrawal of antiviral treatment in kidney transplant recipients with chronic hepatitis B viral infection, Management of patients with hepatitis B who require immunosuppressive therapy, The use of lamivudine for patients with acute hepatitis B (a series of cases), Safety and efficacy of lamivudine in patients with severe acute or fulminant hepatitis B, a multicenter experience, A randomized controlled trial of lamivudine to treat acute hepatitis B, Excellent outcome of Lamivudine treatment in patients with chronic renal failure and hepatitis B virus infection, Management of hepatitis B: 2000—Summary of a Workshop, Results of up to 2 years of entecavir vs lamivudine therapy in nucleoside-naive HBeAg-positive patients with chronic hepatitis B, Tenofovir alafenamide demonstrates broad cross-genotype activity against wild-type HBV clinical isolates and maintains susceptibility to drug-resistant HBV isolates in vitro, Factors associated with HBV virological breakthrough, Long-term monitoring shows hepatitis B virus resistance to entecavir in nucleoside-naive patients is rare through 5 years of therapy, Add-on adefovir is superior to a switch to entecavir as rescue therapy for Lamivudine-resistant chronic hepatitis B. Of these 3 options, TDF is preferred to minimize the risk of emergence of viral resistance during treatment. Persons with inactive CHB should be evaluated for loss of HBsAg annually. The infants of all HBsAg-positive women should receive immunoprophylaxis (HBV vaccination with or without hepatitis B immunoglobulin, per World Heath Organization and Centers for Disease Control and Prevention recommendations). Peg-IFN-α for 12 months is the recommended therapy for those with elevated HDV-RNA levels and ALT elevation. Antivirals with a low genetic barrier to resistance are not recommended because the emergence of resistance can lead to decompensation. Tenofovir and entecavir are preferred because of their potency and minimal risk of resistance, decompensation, and serious side effects. Hepatitis B is a serious liver infection that causes inflammation (swelling and reddening) that can lead to liver damage. The Centers for Disease Control and Prevention has updated guidelines for vaccination and postexposure prophylaxis for health care workers (HCWs).88. These antivirals are minimally excreted in breast milk and are unlikely to cause significant toxicity. APASL Guidelines for HBV -“Asian-Pacific clinical practice guidelines on the management of hepatitis B: a 2015 update” … A qHBsAg <1,500 IU/mL at week 12 resulted in likelihoods of 57% for HBeAg seroconversion and 18% for HBsAg loss. The acute form of hepatitis, generally caused by viral infection, is characterized by constitutional symptoms that are typically self-limiting. People who develop persistent infection (including infants born to hepatitis infected mothers who have evidence of infection at 12 months old) need to be referred to a liver specialist. CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website. However, TAF or entecavir should be considered in patients with decompensated cirrhosis who have renal dysfunction and/or bone disease. Chronic infection requires life-long follow-up, including 6-12 monthly hepatitis B monitoring, yearly hepatitis B DNA viral load, liver function testing and antiviral therapy if indicated. Indicates those who should receive hepatitis B vaccine, if seronegative. Mantzoukis K, Rodríguez-Perálvarez M, Buzzetti E, Thorburn D, Davidson BR, Tsochatzis E, Gurusamy K, Mantzoukis K, Rodríguez-Perálvarez M, Buzzetti E, Thorburn D, Davidson BR, Tsochatzis E, Gurusamy K. Pharmacological interventions for acute hepatitis B infection: an attempted network meta-analysis. (TDF or TAF), Continue entecavir; add tenofovir (TDF or TAF). The prevalence of HBsAg varies greatly across countries, with high prevalence of HBsAg-positive persons defined as ≥8%, intermediate as 2% to 7%, and low as <2%.21, 22 In developed countries, the prevalence is higher among those who immigrated from high- or intermediate-prevalence countries and in those with high-risk behaviors.22, 23, HBV is transmitted by perinatal, percutaneous, and sexual exposure and by close person-to-person contact (presumably by open cuts and sores, especially among children in hyperendemic areas).24, 25 In most countries where HBV is endemic, perinatal transmission remains the most important cause of chronic infection. This treatment duration yields HBeAg seroconversion rates of 20%-31% and sustained off-treatment HBV-DNA suppression of <2,000 IU/mL in 65% of persons who achieve HBeAg to anti-HBe seroconversion. Assessed after 2 years of continuous therapy. Confirmatory testing should be obtained before making a therapy change. There was no evidence of a difference in the proportion of people who progressed to chronic HBV infection between the entecavir and the no intervention groups (OR 0.58, 95% CI 0.23 to 1.49; participants = 131; 1 trial). (Board Liaison), Joseph Ahn, M.D., Alfred Sidney Barritt IV, M.D., M.S.C.R., James R Burton, Jr., M.D., Udeme Ekong, M.D., M.P.H., George Ioannou, M.D., F.A.A.S.L.D., Whitney E.

Singal, M.D. Infection with hepatitis B virus (HBV) can be symptomatic or asymptomatic. Because NAs have no efficacy against HDV infection, they are not recommended in patients with suppressed or low HBV replication except patients with cirrhosis. Peg-IFN is the drug of choice without clear differences in efficacy between pegylated interferon alfa (peg-IFN-α)−2a (180 µg weekly) or −2b (1.5 µg/kg weekly).152 Treatment success, defined as undetectable HDV RNA 24 weeks after completing treatment, ranges from 23% to 57%.152-154 ALT normalization typically parallels the virological responses. In studies of up to 96 weeks, a switch to TAF versus continued TDF treatment (as part of an antiretroviral regimen) was associated with improvements in proteinuria, albuminuria, proximal renal tubular function (mostly within the first 24 weeks), and bone mineral density.20 Collectively, these studies suggest that TAF has a better safety profile than TDF and similar antiviral efficacy in studies of up to 2 years’ duration. HBeAg-positive patients with persistently normal ALT should be tested for ALT at 3- to 6-month intervals. In the absence of other risk factors for osteoporosis or osteomalacia, there is insufficient evidence for or against monitoring of bone mineral density in HBV-infected persons on TDF. One trial reported quality of life at one week; however, the information provided was insufficient to determine whether there was any difference between the interferon and placebo groups. There were no serious adverse events in any of the groups (no intervention: 0/183 (0%), interferon: 0/67 (0%), lamivudine: 0/100 (0%), and entecavir: 0/21 (0%)). Much less commonly with new, more specific anti-HBc tests, anti-HBc may be a false-positive test result, particularly in persons from low-prevalence areas with no risk factors for HBV infection. Hepatitis can be an acute (short-term) infection or a chronic (long-term) infection. This book on Hepatitis B and C contains very useful and recent information about the general characteristics of these common types of chronic liver infections. For pregnant women with immune-active hepatitis, treatment should be based on recommendations for nonpregnant women. Concurrent consideration for liver transplantation is indicated in eligible persons. Hepatitis B antiviral drug resistance mutations in treatment-naïve patients are rare.114 For patients on antiviral therapy, the first manifestation of antiviral resistance is virological breakthrough, which is defined as a 1-log10 (10-fold) increase in serum HBV DNA from nadir during treatment in a patient who had an initial virological response. HBV antiviral therapy should be initiated if there is evidence of HBV reactivation (increase in HBV DNA from baseline—see section 6D1 [Definitions for HBV Reactivation and Associated Outcomes]). All patients evaluated for nonliver solid organ transplantation should be tested for HBsAg, anti-HBc, and anti-HBs. Easl hepatitis b guidelines 2018 pdf Hepatitis B is a serious liver infection caused by hepatitis B virus (HBV). before hepatitis symptom onset until two weeks after symptom onset. To provide data on the … Guidance: TAF is also a preferred initial therapy for adults with immune-active CHB. • Persons who have ever injected drugsaa Even if treatment is successful, it doesn't completely get rid of the hepatitis B virus from the liver. Hepatitis B: An infection caused by a virus that can be spread through blood, semen, and other body fluid infected with the virus. Liver biopsy or noninvasive test results showing no fibrosis and minimal inflammation, 2. Persistence of circulating HBsAg, even in low concentrations, may increase the risk of HDV infection. Practice Nurse form - 'Remote Consultation Request for Initiation of Hepatitis C Treatment' PDF or Word. HBV-DNA levels are very high (typically >1 million IU/mL). Hepatitis B is a serious disease caused by a virus that attacks the liver. Additionally, HBsAg-positive patients with low or undetectable HBV DNA but high ALT levels should be considered for HDV testing. … HBsAg-positive, anti-HBc–positive patients should initiate anti-HBV prophylaxis before immunosuppressive or cytotoxic therapy. Persistent viremia has traditionally been defined as detectable HBV DNA after 48 weeks of treatment. In persons on TDF, renal safety monitoring with serum creatinine, phosphorus, urine glucose, and urine protein should be assessed before treatment initiation and periodically thereafter (e.g., at least annually and more frequently if the patient is at high risk for renal dysfunction or has a preexisting renal dysfunction). Any untreated nonliver recipient undergoing monitoring for reactivation should have ALT and HBV DNA measurements every 3 months for the first year posttransplant and after receipt of T-cell–depleting therapies, such as antithymocyte globulin. Instead, your doctor might recommend rest, proper nutrition and plenty of fluids while your body fights the infection. A phase 3 trial of 873 hepatitis B e antigen (HBeAg)-positive patients (26% with past nucleos(t)ide analogue [NA] therapy) randomized to TAF 25 mg daily or TDF 300 mg daily in a 2:1 ratio found similar 48-week responses, with serum HBV DNA <29 IU/mL in 64% versus 67%, alanine aminotransferase (ALT) normalization in 72% versus 67%, HBeAg loss in 14% versus 12%, and hepatitis B surface antigen (HBsAg) loss in 1% versus 0.3% in the TAF and TDF groups, respectively.17 Week 96 follow-up results likewise showed that 73% and 75% had serum HBV DNA <29 IU/mL, 22% and 18% lost HBeAg, and 1% and 1% lost HBsAg in TAF and TDF patients, respectively.6. This second edition expands the coverage of treatment of various difficult-to-treat patients and will be a welcome guide to the physician in both clinical decision-making and in explaining the benefits and side-effects to the patient. All patients with HBV and HIV coinfection should initiate ARVT, regardless of CD4 count. It has been postulated that the rapid decrease in cortisol levels characteristic of the postpartum state is analogous to the steroid withdrawal therapy that has been used to elicit seroconversion. Management of Hepatitis B 1. Indicates those who should receive hepatitis B vaccine, if seronegative. Reactivation can occur spontaneously, but it is more commonly triggered by immunosuppressive (IS) therapies. Despite an overall high safety profile, lactic acidosis remains a rare but serious side effect with use of any NA and is likely a higher risk in patients with decompensated cirrhosis. Hepatitis B is a vaccine-preventable liver infection caused by the hepatitis B virus (HBV). None of the trials reported quality of life beyond one week or other important outcomes such as death beyond one year, severe progressive liver damage, liver failure, requirement for liver transplantation, or liver cancer. • Donors of blood, plasma, organs, tissues, or semen. However, compensatory mutations that can restore replication fitness frequently emerge during continued treatment, leading to a progressive increase in serum HBV DNA that may exceed pretreatment levels. Patients with low HBV-DNA levels and elevated ALT levels may be considered for HDV screening. On July 27, 2020, the American Society of Clinical Oncology (ASCO) published provisional guidelines recommending that all people diagnosed with cancer be tested for hepatitis B before starting anticancer treatment. Vaccination against HBV is both safe and efficacious during pregnancy.79 In addition, titers of the passively transferred maternal antibody to newborns wane over time, as would be expected without the addition of active vaccination.80 An accelerated vaccination schedule has been shown to be feasible and efficacious in high-risk pregnant women.81 Chronic HBV infection does not usually affect the outcome of pregnancy unless the mother has cirrhosis or advanced liver disease.
