Rifampicin-induced acute tubulointerstitial nephritis during pulmonary tuberculosis treatment: A case report.

Drug-induced tubulointerstitial nephritis is an uncommon complication in patients on anti-tuberculosis therapy that can lead to permanent kidney damage. Rifampicin is the most offending drug. We report a case of a 41-years old man being treated for pulmonary tuberculosis and presenting with tubulointerstitial nephritis associated with rifampicin. We focus on diagnosis features and therapeutic challenges.
