Cryptococcal Infection in Transplant Kidney Manifesting as Chronic Allograft Dysfunction.

Invasive fungal infections (IFIs) are a significant cause of morbidity in solid organ transplant (SOT) recipients. Common causes among them are , , and . Antifungal prophylaxis has led to decrease in overall incidence of IFI; however, there is very little decline in the incidence of Cryptococcal infections of SOT recipients because effective prophylaxis is not available against this infectious agent. Spectrum of manifestation of Cryptococcal infection varies in immunocompetent and immunocompromised host with subclinical and self-limiting with lungs being the primary site in immunocompetent and central nervous system as the most common site in an immunocompromised host. Other preferred sites are cutaneous, pulmonary, urinary tract (prostate) and the bone. Herein, we describe a young adult renal transplant recipient male diagnosed as a rare case of biopsy proven Cryptococcal infection in transplant kidney manifesting as chronic allograft dysfunction.
