Idiopathic sclerosing encapsulating peritonitis.

Sclerosing encapsulating peritonitis (SEP) was diagnosed in two men, one middle-aged woman, and a prepubertal girl, none of whom had been treated with beta-blockers, peritoneal dialysis, or peritoneal shunting. Idiopathic SEP has hitherto been reported mainly in adolescent females. It is hypothesised that in these patients, who were from two adjacent districts of Rajasthan, an aetiological factor was consumption of cereals infected with fungus that contained biologically active amines.
