Prognosis for patients with sclerosing encapsulating peritonitis following CAPD

Area of Science:

• Nephrology
• Gastroenterology
• Surgical Complications

Background:

• Sclerosing encapsulating peritonitis (SEP) is a severe complication of continuous ambulatory peritoneal dialysis (CAPD).
• Understanding SEP's incidence and patient characteristics is crucial for managing CAPD-related morbidity.

Purpose of the Study:

• To investigate the incidence, clinical features, and prognostic factors of sclerosing encapsulating peritonitis (SEP) in CAPD patients.
• To identify subgroups of SEP patients based on prognosis and pre-existing conditions.

Main Methods:

• Retrospective analysis of 197 CAPD patients over 14 years.
• Identification of 7 patients diagnosed with SEP.
• Evaluation of clinical data including ileus, peritonitis severity, ultrafiltration (UF) status, and CAPD duration.

Main Results:

• SEP incidence was 3.7% (7/197 patients), with an annual rate of 2.6/1000.
• All 7 SEP patients presented with ileus; 3 with severe peritonitis and sepsis had transient ileus.
• Poorer prognosis was associated with prior ultrafiltration problems and longer CAPD duration; one patient died within a year.

Conclusions:

• SEP significantly impacts CAPD patient outcomes, with a notable incidence.
• Prognosis varies, potentially allowing for subgroup classification based on UF failure and CAPD duration.
• SEP severely affects quality of life, particularly nutritional intake.
