Clinical outcome of incident peritoneal dialysis patients with diabetic kidney disease

Background Although peritoneal dialysis (PD) is becoming more widespread, PD among diabetic patients carries some concerns, such as worsened glycemic control due to constant exposure to glucose and operational errors due to diabetic complications. However, several technical advances could overcome these disadvantages. We, therefore, aimed to compare technical and patient survival between diabetic and non-diabetic PD patients. Methods We conducted a historical cohort study of 103 patients (mean age, 57 ± 16 years; 75 males, 32 diabetic patients) who started PD between January 2011 and January 2016. Kaplan–Meier survival analysis was used to compare technical and patient survivals between diabetic and non-diabetic patients. Multivariate Cox regression analysis was used to estimate the effects of the presence of diabetes on these outcomes. Results Technical and patient survivals did not differ significantly between groups ( P = 0.62, P = 0.34, respectively). In addition, presence of diabetes affected neither technical nor patient survival in multivariate analysis (hazard ratio [HR], 1.31; 95% confidence interval [CI], 0.58–2.82 and HR 0.80; 95% CI 0.22–2.68, respectively). Conclusions Technical and patient survivals of diabetic PD patients were not inferior to those of non-diabetic PD patients. These results suggest that no hesitation is warranted in initiating PD for diabetic patients with end-stage renal disease.
