The Impact of type 2 diabetes on mortality in end-stage renal disease patients differs between genders.

BACKGROUND/AIMS: In diabetics with end-stage renal disease (ESRD), risk of death has been reported to be non-constant after the first dialysis, and different outcomes have been observed between genders. We assessed the impact of type 2 diabetes (T2DM) on mortality in dialysis regarding its differential effect by gender using time-dependent analyses. METHODS: All T2DM and non-diabetic (no-DM) patients who started dialysis in two renal units in Lyon, France, between January 1, 1995, and December 31, 2007, were included. In multivariate analyses, the Cox model and Shoenfeld residual approach were used to assess the effect of T2DM on dialysis mortality by gender. RESULTS: We included 235 T2DM (males: 57.9%) and 480 no-DM (males: 65.6%) patients. In males, the adjusted hazard ratio (aHR) for death in T2DM versus no-DM was 0.83 (p = 0.20) and was constant over time after the first renal replacement therapy (RRT) (p = 0.88). In females, aHR for death in T2DM versus no-DM patients was not constant over time (p = 0.002). It was 0.64 (p = 0.13) within the first year after the first RRT and 2.10 (p = 0.002) after the first year. Evolutions with time of these aHR by gender were significantly different (p = 0.009). CONCLUSIONS: T2DM was associated with death only in females. This association was not constant over time after the first dialysis.

[Evaluation of information for renal insufficiency patients before dialysis]. / Evaluation de l'information aux patients insuffisants rénaux avant dialyse.

The aim of this audit was to assess the quality of information given to patients before dialysis and to improve the use of this information on the acceptability of the treatment. Methods were those used in medical audit: retrospective data collection in a sample of patients, comparison to a set of standards given by professionals and recommendations disseminated in the group of professionals. Results showed that patients received a partial information on the various techniques used in dialysis. More complete information is needed. Recommendations consisted in a specialised team giving a detailed information on the disease and the techniques used in dialysis, with a psychological assistance. After implementation of this team, re-assessment showed a consistent benefit of structured information and entailed the necessity to improve the process of information delivery by general practitioners and specialists.
