Effect of diabetes on incidence of peritoneal dialysis-associated peritonitis

Several reports on patients with diabetes mellitus (DM) treated by peritoneal dialysis (PD) have shown a higher risk of PD-associated peritonitis compared to non-DM (NDM) patients. The aim of this study was to investigate the incidence of PD-associated peritonitis in DM patients. We divided all patients who received PD at a single center between January 1980 and December 2012 into three groups according to era: Period 1 (n = 43, 1980-1993); Period 2 (n = 123, 1994-2004); and Period 3 (n = 207, 2005-2012). We investigated incidences of PD-associated peritonitis between patients with and without DM. In Periods 1 and 2, incidence of PD-associated peritonitis was higher in the DM group than in the NDM group (P
