Peritoneal dialysis (PD) peritonitis is typically caused by gram-positive bacteria but may be culture negative. Culture-negative peritonitis is often caused by fastidious organisms. Infective peritonitis is a common complication of PD, with an incidence of 42 cases per 100 patient-years,(1) while eosinophilic peritonitis is a rare and poorly described non-infective entity that is often missed or confused for bacterial PD peritonitis. We herein report a case of eosinophilic peritonitis that was treated successfully.
