Summary
Hepatitis A virus rarely causes congenital infections. This case highlights a rare instance of fetal complications, including ascites and meconium peritonitis, following maternal Hepatitis A infection during pregnancy.
Area of Science:
- Virology
- Maternal-fetal medicine
- Pediatric surgery
Background:
- Hepatitis A virus (HAV) is a significant cause of acute viral hepatitis in children and adults.
- Congenital transmission of HAV is exceptionally rare, with limited documented cases.
- Understanding potential fetal complications is crucial for managing maternal infections during pregnancy.
Observation:
- A pregnant individual contracted Hepatitis A at 13 weeks' gestation.
- Ultrasonography revealed fetal ascites at 20 weeks and meconium peritonitis at 33 weeks.
- The infant required surgical intervention for a perforated distal ileum shortly after birth.
Findings:
- The infant exhibited persistent elevated levels of hepatitis A immunoglobulin G (IgG) antibodies 6 months post-delivery.
- These findings suggest a potential transplacental transfer of maternal antibodies and possible fetal immune response.
- The clinical course indicates severe fetal impact from maternal Hepatitis A infection.
Implications:
- This case underscores the importance of considering Hepatitis A in pregnant individuals presenting with unexplained fetal anomalies.
- It highlights the potential for severe gastrointestinal complications in neonates born to mothers infected with Hepatitis A during pregnancy.
- Further research is warranted to elucidate the mechanisms of congenital Hepatitis A transmission and its long-term effects.
