Adenovirus interstitial nephritis and rejection in an allograft.

Abstract

Viral infections are an important complication of solid organ transplantation. Although polyoma is the virus that most commonly infects the renal allograft, adenoviral infections are also reported. We describe the clinical and pathologic findings in a patient with adenoviral infection associated with acute rejection of the renal allograft. The pathologic findings of adenovirus infection usually include a granulomatous interstitial nephritis, which is helpful in distinguishing from acute rejection. We discuss the differential diagnosis and pathophysiology of allograft viral infections and concomitant rejection.
