Abstract
OBJECTIVE
To describe a case of acute interstitial nephritis (AIN) probably related to administration of diltiazem.
CASE SUMMARY
A 53-year-old white man presented to the hospital experiencing abdominal pain radiating to both renal fossae, as well as dysuria. Diltiazem and atenolol had been prescribed to treat an episode of precordial pain associated with effort. An erythematous maculopapular rash developed approximately 2 hours after administration of a single dose of diltiazem, and acute renal failure, associated with elevated liver function test results, developed 6 days later.
DISCUSSION
To the best of our knowledge, this is the third reported case of acute renal failure believed to be induced by diltiazem. In all cases, there was an obvious temporal relationship between administration of diltiazem and the onset of acute renal failure. Previous reports failed to discuss a probable pathogenic mechanism. AIN is the most likely etiology of acute renal failure in our patient. Favorable resolution with no relapse, the presence of the skin rash, and the liver sequelae suggest a common immunoallergic mechanism.
CONCLUSIONS
Healthcare professionals should consider diltiazem-induced AIN in the differential diagnosis of a patient taking diltiazem who develops acute renal failure.
