Cerebral hemorrhage associated with vitamin K deficiency in congenital tuberculosis treated with isoniazid and rifampin.
We report a male infant with congenital tuberculosis who developed cerebral hemorrhage associated with vitamin K deficiency during treatment with isoniazid and rifampin. Despite an absence of risk factors for vitamin K deficiency, the severe hemorrhagic disorder occurred at 4 months of age. We speculate that vitamin K deficiency in the present case may have resulted from a synergic effect of antituberculosis agents and immaturity of vitamin K metabolism and/or its absorption.
