Abstract

Background: Invasive mucormycosis is a very rare infection after kidney transplantation. Here, we report 25 renal transplant recipients with mucormycosis; to our knowledge, this is the largest reported population of mucormycosis in these patients. Material/Methods: In a retrospective study, we collected all kidney transplants with mucormycosis from 9 Transplant Centers of Iran from 1990 to 2010. The definitive diagnosis of mucormycosis was established by obtaining a biopsy specimen of the involved tissue. Results: The most form of disease was rhino-cerebral (n =13), followed by pulmonary (n=7). Overall mortality rate was 52 (n=13), particularly in recipients with pulmonary infection (100); however, the mortality rate in rhino-cerebral form of disease was low (30.8). There was no statistically significant difference in mortality rate between male and female (P=0.8). In addition, no significant differences were seen in mortality rate with age of patients (p=0.8) and time of diagnosis since transplantation (p=0.3). Pulmonary infection was more seen in recipients received azathioprine compared to those on mycophenolate mofetil (p=0.006). Conclusions: Mucormycosis after renal transplantation has a poor prognosis, particularly patients with pulmonary involvement.
