Risk factors for antituberculous chemotherapy-induced hepatotoxicity in Japanese pediatric patients.

Objective: Our objective was to clarify risk factors associated with the development of severe hepatotoxicity during antituberculosis chemotherapy in Japanese children.

Methods: In a retrospective analysis in a 350-bed referral children's hospital in a metropolitan area, the medical charts of all pediatric patients who received antituberculosis chemotherapy between January 1995 and November 1999 were surveyed. Univariate and multivariate analyses were performed to find any demographic parameters (ie, sex, age, height, and body weight), clinical characteristics (ie, nutritional or developmental status, co-infection with hepatitis viruses [B or C] or human immunodeficiency virus, presence of extrapulmonary tuberculosis, or medical history of liver disease), or individual antituberculosis agents used that would be associated with the likelihood of development of severe hepatotoxicity during antituberculous chemotherapy.
