Characteristics of Malaysian infants with biliary atresia and neonatal hepatitis
1Department of Paediatrics, Faculty of Medicine, University Malaya, Kaula Lumpur.
Insights
Infants with neonatal hepatitis or biliary atresia in Malaysia often present late. Early diagnosis of these cholestatic disorders is crucial for better infant survival rates.
Area of Science:
- Pediatrics
- Hepatology
- Neonatology
Background:
- Cholestatic disorders of infancy, including neonatal hepatitis and biliary atresia, are not well-studied in Malaysia.
- These conditions significantly impact infant health and survival.
Purpose of the Study:
- To analyze and compare the clinical features of neonatal hepatitis and biliary atresia in Malaysian infants.
- To identify challenges in differentiating these conditions and suggest improvements in medical care and public awareness.
Main Methods:
- Retrospective study of 93 infants diagnosed with cholestatic disorders between 1982 and 1991 at University Hospital, Kuala Lumpur.
- Comparison of clinical presentation, demographics, and physical findings between biliary atresia and neonatal hepatitis groups.
Main Results:
- Biliary atresia (38%) and neonatal hepatitis (62%) were identified. Neonatal hepatitis showed a male preponderance (P=0.020).
- Significant differences observed in age of presentation, prolonged jaundice, alcoholic stools, liver, and spleen size between the two groups.
- Considerable overlap in clinical features made differentiation difficult, with late presentation noted for infants with cholestasis.
Conclusions:
- Clinical differentiation between neonatal hepatitis and biliary atresia in infants is challenging due to overlapping features.
- Late presentation of cholestatic disorders compromises infant survival.
- Emphasizing these conditions in medical training and increasing public awareness are vital for improving patient outcomes.
Abstract:
Cholestatic disorders of infancy (viz neonatal hepatitis and biliary atresia) have not been well studied in Malaysia. In a retrospective study in the Department of Paediatrics, University Hospital, Kuala Lumpur from January 1982 through December 1991, a total of ninety-three infants with such conditions were identified: 35 (38%) had biliary atresia, 58 (62%) neonatal hepatitis. There was a statistically significant male preponderance in the neonatal hepatitis group (P = 0.020). There was no significant difference in the racial distribution and in the proportions of low birthweight infants between the two groups of disorders. When the biliary atresia group was compared with the neonatal hepatitis group, significant differences were observed in the age of presentation (mean +/- SD) 9.8 +/- 6.8 VS 20 +/- 17.3 weeks (P < 0.001), proportion of infants with prolonged jaundice (> seven weeks) 28/35 (80%) VS 20/58 (34.5%) (P < 0.00001), occurrence of alcoholic stools 26/35 (74.3%) VS 27/58 (46.6%) (P = 0.020), liver size (mean +/- SD): 4.3 (1.6 cm VS 3.3 +/- 1.8 cm (P < 0.01) and splenic size: 2.5 (1.8 cm VS 1.4 (1.2 cm (P < 0.001). There was however considerable overlap between the two groups in these features at presentation, making clinical differentiation between the two conditions difficult. Infants with cholestasis tended to present late, compromising the chance of survival. In order to improve the medical care of these patients, these conditions must be emphasised during the training of medical practitioners, and efforts to increase public awareness of these conditions must be created.
