The changing pattern of diagnosis of infantile cholestasis

Objective: Cholestatic liver disease in infancy is caused by a wide range of conditions. This study reviews the pattern of diagnosis of infants with cholestasis presenting to a tertiary referral paediatric hospital in Sydney, Australia, during a 12‐year period (1985–96). Methodology: Infants aged less than 6 months with cholestasis were identified retrospectively from hospital records and data retrieved from the medical records. Results: There were 205 infants identified as having cholestatic liver disease. The aetiology of the cholestasis was idiopathic in 25%, metabolic/genetic in 23%, and due to obstruction in 20%, parenteral nutrition in 20%, infection in 9% and bile duct hypoplasia in 3%. Conclusions: This study highlights the changing patterns of diagnosis of cholestatic liver disease in infants at a tertiary paediatric facility, demonstrating that up to 50% of cases are now due to genetic/metabolic diseases or parenteral nutrition, and a high proportion are due to idiopathic disease.
