isoniazid, hepatotoxicity, latent tuberculosis infection


Isoniazid (INH) monotherapy has gained widespread acceptance as an efficacious therapy for latent tuberculosis infection (LTBI) especially in low-prevalence settings. Although INH related hepatotoxicity is well recognized, progression to severe liver dysfunction requiring care at a transplant center remains unpredictable. We report the management of a five year-old girl who developed progressive liver failure due to INH prophylaxis. This highlights the potential severity of INH related hepatic injury and underscores the significance of vigilant clinical monitoring throughout the duration of the therapy in children.
