Acute interstitial nephritis secondary to infectious mononucleosis.

Renal involvement in infectious mononucleosis (IM) is infrequent. In most cases it is self-limited and is rarely associated with loss of renal function. The purpose of this case report is to document a case of acute interstitial nephritis (AIN) leading to acute renal failure (ARF) in a patient with Epstein-Barr virus (EBV) infection and to review literature of EBV infection and its renal manifestation. The patient was managed with hemodialysis and steroids and made an uneventful recovery. Renal involvement in IM may be more common than generally appreciated and may occasionally lead to ARF. Therapy with corticosteroids may have role in the management of IM-induced ARF and may shorten the duration of renal failure.
