    Background We investigated associations between baseline use of immunosuppressive drugs and severity of Coronavirus Disease 2019 (COVID-19) in autoimmune hepatitis (AIH). Patients and methods Data of AIH patients with laboratory confirmed COVID-19 were retrospectively collected from 15 countries. The outcomes of AIH patients who were on immunosuppression at the time of COVID-19 were compared to patients who were not on AIH medication. The clinical courses of COVID-19 were classified as (i)-no hospitalization, (ii)-hospitalization without oxygen supplementation, (iii)-hospitalization with oxygen supplementation by nasal cannula or mask, (iv)-intensive care unit (ICU) admission with non-invasive mechanical ventilation, (v)-ICU admission with invasive mechanical ventilation or (vi)-death and analysed using ordinal logistic regression. Results We included 254 AIH patients (79.5%, female) with a median age of 50 (range, 17-85) years. At the onset of COVID-19, 234 patients (92.1%) were on treatment with glucocorticoids (n = 156), thiopurines (n = 151), mycophenolate mofetil (n = 22) or tacrolimus (n = 16), alone or in combinations. Overall, 94 (37%) patients were hospitalized and 18 (7.1%) patients died. Use of systemic glucocorticoids (adjusted odds ratio [aOR] 4.73, 95% CI 1.12-25.89) and thiopurines (aOR 4.78, 95% CI 1.33-23.50) for AIH was associated with worse COVID-19 severity, after adjusting for age-sex, comorbidities and presence of cirrhosis. Baseline treatment with mycophenolate mofetil (aOR 3.56, 95% CI 0.76-20.56) and tacrolimus (aOR 4.09, 95% CI 0.69-27.00) were also associated with more severe COVID-19 courses in a smaller subset of treated patients. Conclusion Baseline treatment with systemic glucocorticoids or thiopurines prior to the onset of COVID-19 was significantly associated with COVID-19 severity in patients with AIH.

    The combination of hepatitis B immunoglobulin and potent nucleos(t)ide analogs after liver transplantation is considered as the standard of care for prophylaxis against hepatitis B virus recurrence. However, the recommended doses, route of administration, and duration of HBIG administration remain unclear. Moreover, hepatitis B immunoglobulin-free prophylaxis with potent nucleos(t)ide analogs has shown promising disease outcomes in preventing hepatitis B virus recurrence. The current recommendations, produced by the Turkish Association for the Study of the Liver, Acute Liver Failure and Liver Transplantation Special Interest Group, suggest a reduced need for hepatitis B immunoglobulin administration with effective long-term suppression of hepatitis B virus replication using potent nucleos(t)ide analogs after liver transplantation.

    The aims of the present study were to evaluate the efficacy and tolerability of ledipasvir/sofosbuvir (LDV/SOF) with or without ribavirin in the treatment of chronic hepatitis C (CHC) in patients with advanced liver disease and to analyse whether the use of LDV/SOF treatment is associated with a new occurrence of hepatocellular carcinoma (HCC) during and after LDV/SOF treatment. The Turkish Early Access Program provided LDV/SOF treatment to a total of 200 eligible CHC patients with advanced liver disease. The median follow-up period was 22months. All patients were Caucasian, 84% were infected with genotype 1b, and 24% had a liver transplantation before treatment. The sustained virological response (SVR12) was 86.0% with ITT analysis. SVR12 was similar among patients with Child-Pugh classes A, B and C disease and transplant recipients. From baseline to SVR12, serum ALT level and MELD score were significantly improved (P<0.001). LDV/SOF treatment was generally well tolerated. Only one patient developed a new diagnosed HCC. Seventeen of the 35 patients, who had a history of previous HCC, developed HCC recurrence during the LDV/SOF treatment or by a median follow-up of 6months after treatment. HCC recurrence was less commonly observed in patients who received curative treatment for HCC compared with those patients who received noncurative treatment (P=0.007). In conclusion, LDV/SOF with or without ribavirin is an effective and tolerable treatment in CHC patients with advanced liver disease. Eradication is associated with improvements in liver function and a reduced risk of developing a new occurrence of HCC.Ledipasvir and sofosbuvir with or without ribavirin is an effective and tolerable treatment in hepatitis C virus-infected patients with advanced liver disease. Eradication is associated with improvements in liver function and reduces the risk of developing a new occurrence of hepatocellular carcinoma.

    Background: The mean platelet volume (MPV) is the most commonly used measure of platelet size and is a potential marker of platelet reactivity. In this study, we aimed to explore the relationship between hepatic histopathology in viral hepatitis and MPV levels, which are associated with platelet count and activity. Materials and Methods: We performed a retrospective case-control study of baseline histological and clinical parameters in chronic hepatitis B and C patients in our tertiary reference center between January 2005 and January 2011. Two hundred and five chronic hepatitis B patients and 133 chronic hepatitis C patients who underwent liver biopsy were included in the study. The patients were divided into two groups: Chronic hepatitis B and chronic hepatitis C and were additionally divided into groups of two according to histological activity index (HAI) and fibrosis scores obtained by liver biopsy results (according to the Ishak scoring system). The clinical characteristics of chronic viral hepatitis patients, including demographics, laboratory (especially MPV), and liver biopsy findings, were reviewed. Results: One hundred and forty-three patients were male (69.1%), and the mean age was 41.9 +/- 12.75 with an age range of 18-71 years in hepatitis B patients. In the classification made according to HAI, 181 patients were in the low activity group (88.3%) and 24 in the high activity group (11.7%). In the evaluation made according to fibrosis score, 169 patients were found to have early fibrosis (82.4%) and 36 were found to have advanced fibrosis (17.6%). In patients with hepatitis B, there was no statistically significant difference in terms of their MPV values between the two groups, separated according to their degree of activity and fibrosis. Sixty-three patients were male (47.3%), and the mean age was 50.03 +/- 12.75 with an age range of 19-75 years. In the classification made according to HAI, 109 patients were in low activity group (81.9%) and 24 in high activity group (18.1%). In the evaluation made according to fibrosis score, 101 patients were found to have early fibrosis (75.9%) and 32 have advanced fibrosis (24.1%). There was a statistically significant difference between the activity and fibrosis groups of the hepatitis C patients (P = 0.04 and P = 0.02, respectively). Conclusion: MPV values are more reliable in hepatitis C patients than hepatitis B for predicting the advanced damage in liver histology. This finding might be useful for the detection of early fibrosis and also starting early treatment, which is important in hepatitis C.
