Background:
Encapsulating peritoneal sclerosis (EPS) is the most severe complication of peritoneal dialysis (PD). Several retrospective reports published between 2007 and 2009 have suggested an increasing incidence of EPS occurring after kidney transplantation. We conducted a prospective observational study to determine the incidence of post-transplantation EPS and identify possible risk factors.
Methods:
Consecutive PD patients undergoing kidney transplantation between 2009 and 2013 were included. Encapsulating peritoneal sclerosis was defined as gastrointestinal obstruction combined with radiological evidence of EPS. Gastrointestinal symptoms were assessed using a self-administered Gastrointestinal Symptom Rating Scale (GSRS) questionnaire. Abdominal computed tomography (CT) was performed prospectively at 6 and 18 months post-transplantation. The primary end point was EPS during follow-up.
Results:
Fifty-three PD patients were included (age 51 ± 14 years). Mean PD duration was 31.3 months. Peritoneal dialysis solutions low in glucose degradation products and icodextrin were used by 86.8% of patients. A fast or average-fast transport status was documented in 83.0%. After a median follow-up of 19 months, complete data of 47 patients were available for analysis. None of the patients developed clinical or radiological signs of EPS. The GSRS score improved from 1.87 to 1.55 (p = 0.024) and body weight increased from 75.9 to 78.3 kg (p = 0.003). Only 1 patient had new onset localized (< 20%) peritoneal thickening on CT 22 months post-transplantation.
Conclusion:
Post-transplantation EPS did not develop in this cohort of patients with a relatively short time of PD exposure. This suggests that these patients can be transplanted safely without concern for the development of EPS, at least within the follow-up period of 19 months.
