Point-of-care Test for Diagnosis of Peritonitis in Peritoneal Dialysis Patients

Overview

Peritoneal dialysis (PD) is a home-based dialysis therapy and peritonitis is a serious complication in PD. A reliable point-of-care test to detect peritonitis is important for patients to self-detect peritonitis at home as delayed diagnosis and treatment of peritonitis will translate to poor outcomes in PD patients. The study aims to examine the effectiveness of Periplex®, point-of-care test, in the diagnosis of peritonitis in PD patients.

A reliable point-of-care test to detect peritonitis is indeed needed for early diagnosis of peritonitis at home and seeking medical help early. We hypothesize that Periplex® is not inferior to routine leukocyte testing of PD Fluid effluent in the diagnosis of peritonitis. The test strip is designed to detect the inflammatory markers (IL6 and MMP-8) which are usually released during peritonitis. The strip is intended to be used in the PD patients who suspected to have symptoms of peritonitis. The target population is all adult PD patients who are followed up in Singapore General Hospital and have signs and symptoms suspected of peritonitis during the study period. The test is considered positive for peritonitis if one or both test lines appear in the window of the test strip. The test will be performed at 2-time points, one at the presentation of peritonitis and one at the completion of antibiotics for the current episode of peritonitis, to document resolution of peritonitis. The results of the tests will be compared with the leukocyte testing of PD effluent.
