Abstract

Aim: Peritoneal dialysis (PD) is the more preferred renal replacement therapy (RRT) option for most patients with end-stage renal disease (ESRD) who can not achieve a kidney transplantation. By an enhanced national PD program, more patients may have a chance to take the advantage of this treatment option. In this study, we aim to investigate whether PD is preferred as the first dialysis treatment modality in Northern Cyprus and reveal the outcomes in order to improve the further PD program.
Material and Method: Peritoneal dialysis patients aged above 18 years who were followed between 2003-2021 in Northern Cyprus were investigated retrospectively. Demographic data, primary kidney diseases, comorbidities and previous RRT modalities were analysed. Episode(s) of peritonitis, total duration on PD therapy, switch to kidney transplantation or HD, and mortality rate were evaluated. Outcomes of elderly (≥ 65 years) and diabetic patients who were dropped out from PD were found out.
Results: A total of 123 patients aged 18-83 years were included in the study. Forty percent of 123 PD patients initiated RRT with PD. The median time was found 1 month in the rest of the patients to transfer PD from other modalities. Renal transplantation was performed in 16.8% of patients during follow-up whereas 34.7% were transferred to HD after 41 months. Inadequate dialysis (40.7%), PD-related infections (29.6%), ultrafiltration insufficiency (18.5%), mechanical complications (11.1%) were the most common causes of switching from PD to HD. The duration of being under PD therapy was 36.5 months for 46 patients who died under PD therapy. Cardiovascular events (50%) and various infections (%35) were the leading causes of mortality. A total of 48 (43.2%) PD patients had at least one episode of peritonitis. Total duration on PD treatment, PD rate as initial RRT modality, the prevalence of hypertension and diabetes mellitus (DM), peritonitis rate, and use of automated PD were not significantly different between elderly (n=34) and adult individuals (18-65 years). The duration of being under PD therapy was longer for males than females (p=0.044) and the duration of PD therapy was similar in the dropped out patients with or without DM (p=0.205).
Conclusion: A significant amount of patients received HD before initiation of PD (60%). Age is not be considered as a challenging barrier for PD initiation in Northern Cyprus. Precautions to prevent the development of peritonitis may contribute to extend the total duration of PD treatment.
