The potential risk of coccidioidomycosis has led to concern about the advisability of maintaining renal transplantation programs in endemic areas. We reviewed the charts of 721 patients undergoing dialysis and 260 renal transplant recipients in Arizona to determine the incidence, risk factors, and clinical course of coccidioidomycosis in these immunosuppressed populations. Symptomatic infection occurred in six (0.83%) patients undergoing dialysis and 18 (6.9%) transplant recipients. Male sex and blood type B predisposed to dissemination. Urine cultures for fungus were important diagnosis aids. Four of six patients with infection limited to the thorax and five of 18 patients with dissemination remained alive after seven months to 7 1/2 years. Although the rate of dissemination (75%) and mortality (63%) from coccidioidomycosis were high, the incidence of infection was low and does not preclude renal transplantation in Arizona. Those who have received transplants elsewhere should be advised not to move or to visit areas endemic for coccidioidomycosis.
