Acute tubulointerstitial nephritis related to antituberculous drug therapy

Abstract

ATIN is a rare, but serious complication of repeat antituberculous therapy mainly due to re-exposure to rifampicin. Although the renal prognosis is generally good the disease does carry significant morbidity and mortality risks. A high index of suspicion is needed in re-treatment patients. A suggested screening test is for microhematuria with urine dipstix.
