Hepatitis D virus seroprevalence in Egyptian HBsAg-positive children: a single-center study.

In this study, we investigated the seroprevalence of anti-hepatitis D virus (HDV) antibodies in hepatitis B surface antigen (HBsAg)-positive children after 25 years of obligatory vaccination of infants against hepatitis B virus. This cross-sectional study included 120 treatment-naïve HBsAg-positive children, with a male-to-female ratio of 1.8:1 and a mean age of 7.

Predictive and Prognostic Value of Ascitic Fluid Mannose Binding Lectin in Patients with Spontaneous Bacterial Peritonitis.

Background: Spontaneous bacterial peritonitis is a common bacterial infection of ascitic fluid, mainly in ascites due to liver cirrhosis. Mannose-binding lectin (MBL) can activate phagocytosis and the complement system. Spontaneous bacterial peritonitis was detected to be higher in MBL deficiency.

SARS-CoV-2: The Path of Prevention and Control.
