Analysis of Survival in Patients with End-End Chronic Kidney Disease Switching from Peritoneal Dialysis to Hemodialysis Due to Refractory Peritonitis

ABSTRACT

Introduction: Peritonitis associated with peritoneal dialysis (PD) has complications such as transfer from PD to HD and increased morbidity and mortality. In our environment, there is little information regarding survival in this population. Method(s) Retrospective cohort, 147 PD patients, 18 years, with PD catheter removal between 2018-2021. Clinical, biochemical and technique-related variables were measured. Patients who died of cancer and other unrelated causes were excluded. Descriptive statistics, Kaplan-Mayer analysis and Cox regression analysis were used Results: Age 42 +- 17 years, 65% men, 65% unknown cause of CKD. The time between peritonitis diagnosis and catheter removal was 37 (25-61) days. Nine patients (6%) returned to PD, the rest (94%) remained on HD due to unfit abdomen (55%), patient decision (9%), unknown (17%), others (19%). Mortality was 31% and the causes of death were sepsis (33%), COVID-19 (29%), pneumonia (19%), pulmonary edema (5%), hyperkalemia (5%), CVD (5%), others (4%). Survival after the refractory peritonitis event was 25 (95% CI 22-28) months. Survival at 3, 12, 24, and 36 months was 87%, 71%, 61%, and 35%. In the bivariate analysis, age, DM, time on dialysis, and serum albumin were associated with a higher risk of death. However, in the multivariate analysis, only time on dialysis was significant (OR 1.014, 95% CI 1.002-1.027). [Formula presented] Conclusion(s) Mortality was 31% and the most frequent cause of death was sepsis. Patient survival was 25 (95% CI 22-28) months. Time on dialysis was associated with a higher probability of death. It is necessary to compare these results with a group of patients who do not present failure of the technique.
