Asymptomatic structural liver disease in hemophilia

Area of Science:

• Hepatology
• Virology
• Hematology

Background:

• Hemophilic patients often receive blood product transfusions.
• Chronic liver function abnormalities are observed in some hemophilic patients.
• Hepatitis B virus (HBV) is a concern in transfusion recipients.

Purpose of the Study:

• To investigate liver histology and HBV presence in hemophilic patients with abnormal liver function tests.
• To determine the relationship between blood product exposure and liver pathology in this cohort.

Main Methods:

• Analysis of 14 liver biopsies from 13 anti-HBs-positive hemophilic patients.
• Histopathological examination including chronic persistent hepatitis, chronic active hepatitis, and fatty infiltration.
• Indirect immunofluorescence to detect hepatitis B viral markers (anti-HBs, anti-HBc) in hepatocytes.

Main Results:

• None of the patients had symptomatic liver disease.
• Chronic hepatitis or fibrosis was observed in all biopsied patients.
• Hepatitis B viral markers were detected in hepatocytes of 8 out of 12 patients studied.

Conclusions:

• Hepatitis B virus can persist in hepatocytes of hemophilic patients, even with circulating antibodies.
• Blood product transfusions may contribute to liver damage and HBV persistence.
• Histological abnormalities suggest ongoing liver injury in these patients.
