RESUMEN
The incidence of hepatitis E continues to increase and in immunocompromised patients can lead to chronic infection. Management of hepatitis E has evolved over time, with the first step being a reduction of immunosuppression followed by treatment with ribavirin. The European Association for the Study of Liver guidelines support treatment with ribavirin although the optimum dose and regime is unknown. This series reviews eight chronically infected cases treated between 2018 and 2021 in two UK centres (Ipswich Hospital and Addenbrooke's Hospital). Treatment response was defined primarily as sustained virological response at 12 weeks (SVR12) following the cessation of treatment and secondly as sustained virological response at 24 weeks (SVR24). The median dose of ribavirin given daily was 600 mg. The management of five of the eight cases was in line with the guidelines, and treatment was stopped after 12 weeks. Two of these five patients achieved SVR (40%). The remaining three cases were given a 24-week course based on clinical judgement, and all achieved SVR (100%). The three patients who relapsed received a second 24-week course of treatment and achieved SVR. Therefore, with a 24-week course, a 100% treatment success rate was attained. In chronic hepatitis E, a 24-week course of ribavirin would achieve optimum clearance rates with a single course of treatment. Ensuring the highest dose of ribavirin as possible (aiming to reach 800 mg daily) and attempts to reduce immunosuppressive therapy safely may also be relevant to achieving SVR.

The main aim of this educational article ( narrative review ) is to reflect clinical practice guidelines of the European Association for the Study of the Liver (EASL) published in J Hepatol 2018, contrasting with the 2012 guidelines especialy in the new terminology of alcohol-related liver diseases (ALD). The strong emphasis on prevention of alcohol use disorders (AUD) may be exert at all stages of public health care. Another aim of the article are ALD history, epidemiology, metabolism of alcohol and clinical pictures of ALD.

BACKGROUND & AIMS: Patients with autoimmune hepatitis (AIH) commonly receive induction therapy with predniso(lo)ne followed by maintenance therapy with azathioprine. European Association for Study of the Liver clinical practice guidelines advise a predniso(lo)ne dose range of 0.50-1 mg/kg/day, which leaves room for practice variation. We performed a multicenter study to determine the efficacy of different dose ranges of predniso(lo)ne induction therapy in a large European cohort of patients with AIH. METHODS: We performed a retrospective cohort study using a comparative effectiveness design. We collected data from 451 adults with AIH who began treatment from 1978 through 2017 at 9 centers in 5 European countries. We assigned patients to a high-dose group (initial predniso(lo)ne dose ≥0.50 mg/kg/day; n = 281) or a low-dose group (<0.50 mg/kg/day; n = 170). Logistic regression was performed to determine difference in outcomes between the groups. The primary outcome was normal serum levels of transaminases at 6 months after initiation of therapy. RESULTS: There was no significant difference in rates of normalization of transaminases between the high-dose predniso(lo)ne group and the low-dose group (70.5% vs 64.7%; P = .20). After multivariable logistic regression with correction for confounders, there was no difference in the likelihood of normalization of transaminases between the groups (odds ratio, 1.21; 95% CI, 0.78-1.87; P = .38). Patients given an initial high dose of predniso(lo)ne received more predniso(lo)ne over time than patients started on a lower dose (median doses over 6 months: 3780 mg vs 2573 mg) (P < .01). CONCLUSIONS: In a retrospective study of patients with AIH in Europe, we found that the dose of predniso(lo)ne to induce remission in patients with AIH is less relevant than assumed. An initial predniso(lo)ne dose below 0.50 mg/kg/day substantially decreases unnecessary exposure to predniso(lo)ne in patients with AIH.

Hepatitis B virus (HBV) infection remains a global public health problem with changing epidemiology due to several factors including vaccination policies and migration. This Clinical Practice Guideline presents updated recommendations for the optimal management of HBV infection. Chronic HBV infection can be classified into five phases: (I) HBeAg-positive chronic infection, (II) HBeAg-positive chronic hepatitis, (III) HBeAg-negative chronic infection, (IV) HBeAg-negative chronic hepatitis and (V) HBsAg-negative phase. All patients with chronic HBV infection are at increased risk of progression to cirrhosis and hepatocellular carcinoma (HCC), depending on host and viral factors. The main goal of therapy is to improve survival and quality of life by preventing disease progression, and consequently HCC development. The induction of long-term suppression of HBV replication represents the main endpoint of current treatment strategies, while HBsAg loss is an optimal endpoint. The typical indication for treatment requires HBV DNA >2,000IU/ml, elevated ALT and/or at least moderate histological lesions, while all cirrhotic patients with detectable HBV DNA should be treated. Additional indications include the prevention of mother to child transmission in pregnant women with high viremia and prevention of HBV reactivation in patients requiring immunosuppression or chemotherapy. The long-term administration of a potent nucleos(t)ide analogue with high barrier to resistance, i.e., entecavir, tenofovir disoproxil or tenofovir alafenamide, represents the treatment of choice. Pegylated interferon-alfa treatment can also be considered in mild to moderate chronic hepatitis B patients. Combination therapies are not generally recommended. All patients should be monitored for risk of disease progression and HCC. Treated patients should be monitored for therapy response and adherence. HCC remains the major concern for treated chronic hepatitis B patients. Several subgroups of patients with HBV infection require specific focus. Future treatment strategies to achieve 'cure' of disease and new biomarkers are discussed.
