HBsAg-positive giant cell hepatitis with cirrhosis in a 10-month-old infant

Insights

A Japanese boy developed acute hepatitis B from his carrier mother. Giant cell hepatitis with cirrhosis was diagnosed, and he cleared the virus by 19 months.

Area of Science:

  • Hepatology
  • Virology
  • Pediatrics

Background:

  • Perinatal transmission of Hepatitis B virus (HBV) can lead to chronic infection.
  • Maternal carriage of Hepatitis B surface antigen (HBsAg) and Hepatitis B e-antigen (HBeAg) increases transmission risk.
  • Vertical transmission can result in severe liver disease in infants.

Observation:

  • A Japanese infant born to an asymptomatic HBsAg and HBeAg carrier mother developed acute Hepatitis B at 6 months.
  • Clinical presentation included hepatosplenomegaly and abnormal liver function tests.
  • Liver biopsy revealed giant cell hepatitis with cirrhosis at 10 months of age.

Findings:

  • Hepatitis B virus surface antigen (HBsAg) was detectable from 6 to 19 months of age.
  • The child did not develop antibodies to HBsAg (anti-HBs) or HBeAg (anti-HBe).
  • Alternate-day prednisolone therapy was administered for 7 months.

Implications:

  • This case highlights the potential for severe liver disease in infants with vertically transmitted Hepatitis B.
  • Spontaneous clearance of Hepatitis B virus occurred despite initial severe pathology.
  • Further research is needed on the long-term outcomes and management of such cases.
