Peritonitis is a common and life-threatening complication of acute peritoneal dialysis (PD). Diagnosis requires the presence of clinical signs of peritonitis which are nonspecific and laboratory investigations [total leukocyte count (TLC), Gram-stain, and culture of PD effluent fluid] which are time-consuming and not available at the bedside. In this study, we evaluated the use of leukocyte esterase reagent strip (LERS) as a bedside test to diagnose peritonitis in patients undergoing acute PD. Patients who underwent acute PD were monitored for signs and symptoms of peritonitis. PD effluent fluid analysis included TLC, absolute neutrophil count, Gram-stain, and culture for the diagnosis of peritonitis. LERS (Multistix 10SG) was simultaneously dipped in PD effluent fluid and read at two minutes. Reading of + was considered as indicative of peritonitis. Twenty-one out of 166 (12.6%) patients undergoing acute PD developed peritonitis. LERS detected peritonitis in 20 patients. The sensitivity, specificity, positive predictive value, and negative predictive value (NPV) of LERS were 95.2%, 95.2%, 74.1%, and 99.3%, respectively. LERS has very high sensitivity and NPV and can be used as a rapid bedside tool to exclude peritonitis in patients undergoing acute PD.
