Neonatal hepatitis: a follow-up study
1Department of Pediatrics, National Taiwan University, Republic of China.
Insights
Neonatal hepatitis outcomes vary; high bilirubin and specific liver findings predict poor prognosis. Cytomegalovirus (CMV) infection is common, but metabolic disorders were not identified in this cohort.
Area of Science:
- Pediatrics
- Hepatology
- Virology
Background:
- Neonatal hepatitis presents a significant challenge in pediatric liver disease.
- Understanding prognostic factors is crucial for managing affected infants.
Purpose of the Study:
- To identify predictors of outcome in infants with moderate to severe neonatal hepatitis.
- To investigate the role of Cytomegalovirus (CMV) infection and metabolic disorders.
Main Methods:
- Longitudinal follow-up of 56 infants with neonatal hepatitis for 12-78 months.
- Assessment of clinical data, liver histology, and screening for metabolic disorders.
- Detection of Cytomegalovirus (CMV) infection.
Main Results:
- Of 54 evaluable patients, 45 recovered without liver disease, 7 died of hepatitis, and 2 had chronic liver disease.
- High peak bilirubin levels and specific histological findings (periportal fibrosis, portal inflammation, giant cell transformation) predicted poor outcomes.
- Cytomegalovirus (CMV) infection was present in 49% of patients, with some experiencing severe outcomes.
Conclusions:
- High peak bilirubin and specific liver histology are key predictors of poor neonatal hepatitis outcomes.
- Cytomegalovirus (CMV) is a frequent co-infection, impacting prognosis.
- Further investigation into familial and metabolic cholestasis in Chinese infants is warranted.
Abstract:
Fifty-six patients with moderate to severe neonatal hepatitis were followed for 12 to 78 months. Two died from causes other than hepatitis itself and were free from liver disease at the time of death. Of the remaining 54 patients, seven died of hepatitis, two are living with chronic liver disease and psychomotor retardation, and 45 are living without liver disease. High peak bilirubin levels and liver histologic findings of periportal fibrosis, moderate to severe portal inflammation, and/or diffuse giant cell transformation appear to be major factors predictive for poor outcome. Cytomegalovirus (CMV) infection was a common associated infection. Evidence of CMV infection was found in 22 (49%) of the 45 patients studied. Three of them died, and one is still living with cirrhosis of the liver. Metabolic disorders such as alpha-1-antitrypsin deficiency, galactosemia, and aminoaciduria and/or aminoacidemia were carefully screened but were not found in these cases. A fatal case had a sibling who had died of a similar disease course. Chinese infants may have metabolic and familial cholestasis diseases requiring further investigation.
