[Vertical transmission of hepatitis. 3 years' follow-up]
Insights
An infant developed chronic aggressive hepatitis B, likely from vertical transmission. Early postpartum passive-active immunization for at-risk newborns is crucial for preventing chronic hepatitis B infection.
Area of Science:
- Hepatology
- Virology
- Immunology
Background:
- Hepatitis B virus (HBV) infection can lead to chronic disease.
- Vertical transmission from mother to infant is a significant route of HBV acquisition.
- Asymptomatic carriers pose a risk for HBV transmission.
Observation:
- An infant presented with acute hepatitis B infection that progressed to a chronic aggressive form.
- Immunoserologic markers indicated vertical transmission of hepatitis B virus from mother to infant.
- The mother was an asymptomatic carrier of hepatitis B surface antigen (HBsAg) but negative for hepatitis B e-antigen (HBeAg).
Findings:
- Vertical transmission is a likely cause of chronic aggressive hepatitis B in the infant.
- Maternal HBsAg carriage, even without HBeAg, can result in infant infection.
- Early detection and intervention are critical for managing HBV in newborns.
Implications:
- Routine screening for HBsAg in pregnant women is essential for identifying at-risk infants.
- Postpartum passive-active immunization for newborns at risk should be administered as early as possible.
- Implementing effective prevention strategies can reduce the incidence of chronic hepatitis B infection.
Abstract:
An infant with an acute hepatitis B infection developed the chronic aggressive form of the disease. The immunoserologic findings in the child and his mother suggest a vertical hepatitis B virus transmission. The mother was found to be an asymptomatic HBs-Ag carrier but HBe-Ag negative. The importance of a screening program for HBs-Ag in pregnant women is discussed. It is suggested that newborns at risk should get passive-active immunisation post partum as early as possible.
