Background

To investigate whether patient and technique survival in peritoneal dialysis (PD) are related to timing of first peritonitis.

Methods


In this retrospective study, 144 patients on peritoneal dialysis who were 18 years of age and older and had at least one episode of peritonitis between 2004 and 2016 were included. They were divided into early peritonitis (EP) group (n = 97) which included patients who had their first peritonitis within 12 months from start of PD therapy, and late peritonitis (LP) group (n = 47) which included patients who had their first peritonitis after 12 months from start of PD therapy. Technique and patient survival of both groups were compared in terms of time following first incident peritonitis using Cox proportional hazard model.

Results

EP group had shorter time on PD therapy compared to LP group (median 16.7 ± 13.1 vs 39.8 ± 20.1 months respectively, p < 0.001). However, EP and LP groups had similar patient survival in relation to time following first incident peritonitis (16 % vs 19 % at 24 months, HR: 0.96, CI 95%: 0.84 – 1.23, p = 0.9) and similar technique survival (16% for both groups at 24 months, HR: 1, CI 95%: .96 – 1.04, p = 0.7). There was no difference in causal microorganisms between both groups (p = 0.45).

Conclusion

Incident first peritonitis is associated with short patient and technique survival independently of time taken to develop the event.
