PERSPECTIVES Innate Immunity to Enteric Hepatitis Viruses

Although hepatitis A virus (HAV) and hepatitis E virus (HEV) are both positive-strand RNA viruses that replicate in the cytoplasm of hepatocytes, there are important differences in the ways they induce and counteract host innate immune responses. HAV is remarkably stealthy because of its ability to evade and disrupt innate signaling pathways that lead to interferon production. In contrast, HEV does not block interferon production. Instead, it persists in the presence of an interferon response. These differences may provide insight into HEV persistence in immunocompromised patients, an emerging health problem in developed countries.

In this study, we assessed whether there were any survival advantages with a combination treatment of intravenousN-acetylcysteine (NAC) and prednisone over prednisone alone in those with severe alcoholic hepatitis [discriminant function (DF)  ≥ 32].Patients and MethodsBetween January 1, 2013, and February 28, 2019, we identified 68 patients (mean age 47.2  years ± 10.1, 57% women, 65% cirrhosis, MELD score 28.1 ± 6.6) with alcoholic hepatitis, and of those, 21 (31%) received prednisone and 47 (69%) received prednisone + NAC. Lille score &g...

We present a 13-year old previously healthy Omani with fatal hepatitis A virus infection. This case highlights the critical role of hepatitis A vaccination and argues for consideration of its inclusion in national vaccination programs in order to avert similar devastating consequences of yet another vaccine preventable disease.

Authors: Khoury T, Kadah A, Mari A, Sbeit W, Drori A, Mahamid M Abstract BACKGROUND: Autoimmune hepatitis (AIH) may be associated with other autoimmune diseases. Autoantibodies are common in AIH suggesting their potential role in the pathogenesis of the disease. Among these autoantibodies, thyroid autoantibodies have been reported in patients with chronic hepatitis, with greater prevalence in patients with chronic hepatitis C infection. OBJECTIVES: To assess the prevalence of thyroid dysfunction among patients with AIH. METHODS: In this case-control, retrospective study, we examined patients diagnosed with ...
