|Title:||Better outcomes of peritoneal dialysis in diabetic patients in spite of risk of loss of autonomy for home dialysis|
|Abstract:||Introduction: Diabetes mellitus is a leading cause of chronic renal failure, challenging therapy strategies. Patients with diabetes may benefit from peritoneal dialysis (PD) but higher technique failure is feared. Our purpose was to critically evaluate clinical outcomes of this modality in diabetics, in order to find quality improvement strategies in these risk patients. Methods: A registry-based study of 432 incident patients, 23% with diabetes, from a university hospital PD program was performed. Traditional methods (Kaplan-Meier, Cox models) and innovative survival analysis, taking competing risks into account, were performed, as well as exploring the trends in cohorts according to the decade of PD start. Results: In spite of the detrimental effect of diabetes in patient survival compared to non-diabetics (77%, 52% vs 86%, 71%, at 2 and 4 years, respectively; p < 0.0001) the hazard ratio (HR) for death decreased in the more contemporary cohort (0.303, 95% confidence interval (CI) 0.150 - 0.614, p < 0.001). It is noteworthy that diabetes was not associated with lower technique survival: 74%, 51% vs 79%, 57%, at 2 and 4 years, respectively (p = not significant (NS)). On multivariate analysis, diabetes was an independent predictor for mortality, but not for technique failure. The hazard ratio (HR) for technique failure also decreased in the more recent cohort (0.566, 95% CI 0.348 - 0.919, p = 0.021). Among reasons for transfer to hemodialysis, proportion of ultrafiltration failure was similar between groups (26% vs 22%, p = NS), but drop-out due to loss of autonomy occurred more in the group with diabetes (23% vs 5%, p = 0.004), mainly due to ischemic stroke. The hospitalization rate was also higher in diabetic patients (1.39 vs 0.84 episodes per patient-year (E/PY), p = 0.004) but the peritonitis rate was not increased (0.53 vs 0.61 E/PY, p = NS). Conclusion: PD was an effective long-term renal replacement therapy in diabetics, without higher rates of technique failure, ultrafiltration failure or peritonitis. Better outcomes were achieved in the contemporary cohort. The menace of autonomy loss due to stroke and higher hospitalization rates enhance the need for assisted PD strategies and better control of comorbidities.|
