BACKGROUND: Both diabetes and hypertension, two conditions that can lead to renal failure, have a high prevalence in Guadeloupe. OBJECTIVE: To determine the clinical and epidemiological features of diabetic patients on end stage renal failure and to evaluate their survival. PATIENTS AND METHOD: Data of the Guadeloupe Kidney registry were analysed for patients who began chronic dialysis during 1978-1997. Follow up information on survival status was obtained up to January 26(th) 1999. Cox proportional hazard analysis was used to determine the relative risk (RR) of death between levels of independant variables. RESULTS: There were 784 dialysis patients of whom 174 (22%) were diabetics. Among the latter, there were 97 women (55,7%), mean age at the start of dialysis was 60.6 years (range 26-83) and arterial hypertension was present before the start of dialysis in 67% of them. Median survival MS (95%CI) was significantly lower in diabetics 42 months (31-52) than in non diabetics 83 months (70-96), p<10(-4). In diabetics, the cumulative probability of survival was 83% (1 year) and 39% (5 years) and the RR of death (95% CI) were 1.90 (1.10-3.22) and 3.43 (2.00-5.87) for diabetics admitted in dialysis in age-class 55-64 years and 65-83 years, respectively, when that for age-class 54 years was set at 1. 00. The RR for diabetics was 1.67 (1.33-2.10) relative to non diabetics. CONCLUSION: Prospective studies are warranted to describe the role of comorbid conditions in diabetic patients survival. Prevention of degenerative complications should be a priority in this population.
