Nephrogenic diabetes insipidus and tubulointerstitial nephritis during continuous therapy with rifampin.

ABSTRACT

While receiving continuous daily rifampin therapy, a 57-year-old man developed acute renal failure and nephrogenic diabetes insipidus due to acute tubulointerstitial nephritis which was reversible by discontinuing the rifampin. Tubulointerstitial nephritis rarely develops during continuous rifampin therapy, and associated nephrogenic diabetes insipidus has not previously been reported. The majority of cases of tubulointerstitial nephritis due to rifampin have occurred following reintroduction of rifampin after an interruption in therapy. The clinical differences between patients developing tubulointerstitial nephritis during interrupted and continuous therapy are discussed.
