Renal allograft recipient with co-existing BK virus nephropathy and pulmonary histoplasmosis: Report of a case. Clin Exp Nephrol. 2010 Dec;14(6):641-4

Renal allograft recipients are prone to opportunistic infections, rarely multiple coexisting infections, due to the immunocompromised state. To the best of our knowledge, no case of a co-existing polyoma virus nephropathy and pulmonary histoplasmosis in a renal allograft recipient has been reported so far in the available literature. A 55-year-old male renal allograft recipient underwent graft biopsy for asymptomatic graft dysfunction. The graft biopsy showed features of polyoma virus nephropathy. Soon after, he developed fever with pulmonary nodules. Fine-needle aspiration from lung nodules showed intracellular yeast forms of histoplasma. The patient responded well to amphotericin B with subsidence of fever. The co-existence of renal allograft-limited infection like polyoma virus and systemic fungal infection such as histoplasmosis should be kept in mind in a transplant recipient with graft dysfunction and non-specific systemic symptoms. Prompt recognition of these infections permits the clinician to institute appropriate therapeutic modification and improved survival.
