Eosinophilic peritonitis responding to treatment with glycyrrhizin.

A 63-year-old man with diabetes mellitus for 15 years was admitted to our hospital in 1990 because of end-stage renal failure. Five days after beginning continuous ambulatory peritoneal dialysis (CAPD) he developed an eosinophilic peritonitis (EP). With protein loss in the dialysate and a decreased serum albumin level, the patient developed ankle edema. The patient was treated with glycyrrhizin, and his EP resolved. It is suggested that an allergic background may play an important role in the development of EP in patients on CAPD.
