Insights
Bacillus Calmette-Guérin (BCG) vaccination can cause rare complications like granulomatous hepatitis. Early diagnosis and treatment in infants are crucial for recovery and preventing further issues.
Area of Science:
- Pediatrics
- Infectious Diseases
- Hepatology
Background:
- Bacillus Calmette-Guérin (BCG) vaccination is a common preventative measure against tuberculosis.
- While generally safe, BCG can lead to rare disseminated complications.
- Hepatosplenomegaly and diarrhea are presenting symptoms in infants with potential BCG complications.
Observation:
- A 2-month-old infant presented with hepatosplenomegaly and diarrhea.
- Liver biopsy revealed multiple granulomas with epithelioid histiocytes in portal and lobular areas.
- This histological pattern suggested granulomatous hepatitis.
Findings:
- The infant was diagnosed with granulomatous hepatitis, a rare complication of BCG vaccination.
- Treatment with isoniazid, rifampine, and ethambutol was initiated.
- An 8-month follow-up showed normalized liver function tests and reduced hepatosplenomegaly.
Implications:
- Epithelioid cell granulomas in the liver can signify disseminated BCG infection.
- Prompt diagnosis and appropriate anti-tuberculosis therapy are essential.
- Timely intervention can prevent severe outcomes and long-term sequelae in affected infants.
Abstract:
Bacillus Calmette-Guérin (BCG) vaccine, which is a widely practiced vaccine in some regions, could lead to a variety of complications. Herein, a 2-month-old infant is presented who was referred because of hepatosplenomegaly and diarrhea. Liver biopsy indicated multiple small and large granulomas composed of epithelioid histiocytes; granulomas resided in portal or lobular areas. The diagnosis of granulomatous hepatitis was made, and treatment with isoniazid, rifampine, and ethambutol were started. Liver function tests were normalized and hepatosplenomegaly was reduced in an 8-month follow-up. The presence of epithelioid cell granuloma in the liver may indicate a diagnosis of disseminated BCG as a rare complication of vaccination. Prompt diagnosis and appropriate treatment could prevent further complications in the affected patients.
