High incidence of early posttransplantation diabetes mellitus in an eastern population

The prevalence of diabetes mellitus (DM) in the Gulf region is among the highest in the world. In the general population of Oman, the rate is approximately 11.7% with an additional 6.1% of the population having an abnormal glucose tolerance. This study reviewed the data for 162 adults who received kidney transplants between 2001 and 2004. The immunosuppression regimen was cyclosporine, mycophenolate mofetil (MMF), and steroids. The mean age of the group was 40.2 years. Twenty-two patients (13.6%) had DM prior to transplantation. Within the first 2 months after transplantation, 45 (32%) of the remaining 140 patients required insulin, and 10 (7.1%) required oral agents. A further 16 patients (11.4%) displayed blood glucose levels >11 mmol/L, but required only a special diet for control. The data indicate that 50% of recent adult kidney recipients in Oman receiving cyclosporine develop posttransplantation DM. This major problem in our transplant population requires special attention. Protocols with minimal steroid use and/or steroid withdrawal may be beneficial for the Oman kidney recipient population.
