Influence of Early-Onset Peritonitis on Mortality and Clinical Outcomes in ESRD Patients with Diabetes Mellitus on Peritoneal Dialysis: A Retrospective Multicenter Study.
2021
INTRODUCTION The impact of early-onset peritonitis (EOP) on patients with diabetes undergoing peritoneal dialysis (PD) has not been adequately addressed. We therefore sought to investigate the effects of EOP on the therapeutic response to management and long-term prognostic outcomes in patients with diabetes undergoing PD. METHODS For this retrospective cohort study, we analyzed the data for patients with end-stage renal disease, who were also suffering from diabetes mellitus and had undergone PD between January 1, 2013, and December 31, 2018. EOP was defined as the first episode of peritoneal dialysis-related peritonitis (PDAP) occurring within 12 months of PD initiation. All patients were divided into an EOP group and a later-onset peritonitis (LOP) group. Clinical data, treatment results, and outcomes were compared between groups. RESULTS Ultimately, 202 patients were enrolled for the analysis. Compared to the EOP group, the LOP group had more Streptococcus (p = 0.033) and Pseudomonas (p = 0.048). Patients with diabetes in the EOP group were less likely to have PDAP-related death (OR 0.13, CI: 0.02-0.82, p = 0.030). Patients with diabetes in the EOP group were more likely to have multiple episodes of PDAP and had higher rates of technical failure and poorer patient survival than those in the LOP group, as indicated by Kaplan-Meier analysis (p = 0.019, p = 0.004, and p < 0.001). In the multivariate Cox proportional hazards model, EOP was a significant predictor for multiple PDAP (HR 4.20, CI: 1.48-11.96, p = 0.007), technical failure (HR 6.37, CI: 2.21-18.38, p = 0.001), and poorer patient survival (HR 3.09, CI: 1.45-6.58, p = 0.003). CONCLUSIONS The occurrence of EOP is significantly associated with lower rates of PDAP-related death and poorer clinical outcomes in patients with diabetes undergoing PD.
