title: High incidence of post-transplant diabetes mellitus in Kuwait.
abstract: Post-transplant diabetes mellitus (PTDM) has been reported to occur in 5-15% of non-diabetic renal transplant recipients. During a 15-year period (January 1983-January 1998), 631 renal transplant recipients (TxR) were followed-up in our Centre of whom 79 (12.5%) had pre-transplant diabetes mellitus. Among the 552 TxR who were non-diabetic at pre-transplantation, 117 (21.2%) developed PTDM. The gender, native renal disease and the mode of pre-transplant dialysis did not differ in those with and without PTDM. Of the 117 TxR who developed PTDM, 63 (53.8%) were above the age of 45 years where as only 90 (20.7%) of the 435 who remained non-diabetic (NDM) were above this age (P<0.05). PTDM occurred in 115 (29.6%) recipients of Arab origin (Kuwaitis and non-Kuwaitis) where as only two (1.7%) non-Arabs developed it. There was no difference in the incidence of PTDM when prednisone and azathioprine (two drug regime) were used or with cyclosporine (triple drug regime). The incidence of acute rejection episodes did not differ among PTDM and NDM groups. The over all incidence of infections requiring hospitalisation was higher in PTDM group (1.8 episodes per patient) compared to NDM group (one episode per patient) during the study period (P<0.001). Coronary heart disease was also more frequent in PTDM (15 vs. 6%, P<0.05). The cumulative graft survival at 1, 5, 10 and 14 years in the PTDM (97, 92, 74 and 67%, respectively) and NDM groups (97, 91, 80 and 73%, respectively) was similar. However, an important cause of graft loss was death of the recipient in PTDM compared to NDM (10.7 vs. 3.6%). Similarly, the patient survival up to 14 years did not differ between PTDM and NDM groups (80 and 82%, respectively), although infection related deaths were more frequent in the PTDM group (65 vs. 49%) although not statistically significant. In conclusion, there is a high incidence of PTDM in Kuwait; age and race being the two important contributory factors. The overall patient and graft survival are not adversely affected by PTDM although infections and coronary heart disease are more frequently encountered in this group.
