ABSTRACT

BACKGROUND: Characteristics of hepatitis B (HBV) and delta (HDV) coinfection in various geographical regions, including Israel, remain unclear. Here we studied HDV seroprevalence in Israel, assessed HDV/HBV viral loads, circulating genotypes and hepatitis delta antigen (HDAg) conservation. METHODS: Serological anti HDV IgG results from 8969 HBsAg positive individuals tested in 2010-2015 were retrospectively analyzed to determine HDV seroprevalence. In a cohort of HBV/HDV coinfected (n=58) and HBV monoinfected (n=27) patients, quantitative real-time PCR (qRT-PCR) and sequencing were performed to determine viral loads, genotypes and hepatitis delta antigen (HDAg) protein sequence. RESULTS: 6.5% (587/8969) of the HBsAg positive patients were positive for anti HDV antibodies. HDV viral load was >2 log copies/ml higher than HBV viral load in most of the coinfected patients with detectable HDV RNA (86%, 50/58). HDV genotype 1 was identified in all patients, most of whom did not express HBV. While 66.6% (4/6) of the HBV/HDV co-expressing patients carried HBV-D2 only 18.5% (5/27) of the HBV monoinfections had HBV-D2 (p=0.03). Higher genetic variability in the HDAg protein sequence was associated with higher HDV viral load. CONCLUSIONS: The overall significant prevalence of HDV (6.5%) mandates HDV RNA testing for all coinfected patients. Patients positive for HDV RNA (characterized by low HBV DNA blood levels) carried HDV genotype 1. Taken together, the significant HDV seroprevalence and the lack of effective anti-HDV therapy, necessitates strict clinical surveillance especially in patients with higher HDV viral loads and increased viral evolution.

ABSTRACT

Percutaneous liver biopsy (PLB) is a common procedure in patients with liver disease. Bleeding after PLB is rare, with an incidence of 0.35%. Most bleeding complications present within 24 h after biopsy. A 56-year-old woman was admitted to our hospital due to severe and sudden right upper quadrant (RUQ) abdominal pain 10 days after ultrasound (US)-guided PLB. CT study revealed both intrahepatic and intraperitoneal bleeding, and Hb levels decreased by 3.2 g/dl within a few hours. Such a prolonged delay in PLB-related bleeding has not been previously described in the medical literature. LEARNING POINTS: Bleeding after liver biopsy is very rare, with an incidence of 0.35%.Approximately 95% of bleeding complications occur within 24 h.Physicians should be aware of rare delayed presentation in the days following liver biopsy.

ABSTRACT

Spontaneous bacterial empyema, a complication of hepatic hydrothorax in cirrhotic patients, is a rare but nevertheless important medical entity. The diagnosis, treatment and prognosis of spontaneous bacterial empyema differs from the "usual" empyema, and avoiding proper diagnosis or treatment delay may have far reaching consequences. We report on a patient who was diagnosed in our department with spontaneous bacterial empyema, review the main current literature on the subject and elaborate on the specific therapeutic considerations related to the case management.

ABSTRACT

Biliary symptoms may be an unusual presentation of portal hypertension, especiaLly in patients with portal vein thrombosis. This is a case report of a patient who developed acute and chronic portal vein thrombosis that presented as obstructive jaundice. The discussion will focus on diagnostic modalities and therapeutic options.
