BACKGROUND AND AIM: The postinfectious irritable bowel syndrome (PI-IBS) frequently follows bacterial infections. Since people suffering from PI-IBS and Trichinella spiralis-infected mice develop similar findings, this animal model has been successfully used for PI-IBS studies; however, IBS has never been studied in humans after trichinellosis. The aim of this study was to evaluate the IBS symptoms in people who had acquired trichinellosis. PATIENTS AND METHODS: A large outbreak of trichinellosis caused by Trichinella britovi occurred in Izmir, Turkey, in 2003-2004. The diagnosis of trichinellosis was confirmed by serology and muscle biopsy. After clinical and laboratory evaluations, 72 patients (38 women, 34 men, mean age 33.2 +/- 10.4 yr) with trichinellosis without preexisting IBS were enrolled in the study. Noninfected people (N = 27) were used as control group. A questionnaire was developed to assess symptoms of IBS and alarm symptoms. The first interview was done face-to-face. After 2, 4, and 6 months of the first interview, the questionnaire was readministered to the patients without any information on the occurrence of a previous trichinellosis syndrome, while it was applied after a year only to the patients who had suffered IBS symptoms according to at least one of the previous interviews. RESULTS: According to Rome II criteria, PI-IBS developed in 10 of 72 (13.9%) people with confirmed trichinellosis, who had no preexisting IBS. The rate of PI-IBS was 13.9% and 13.9% at the 4th and 6th months, respectively. The symptoms of PI-IBS persisted in five of them up to 1 yr. People without trichinellosis did not develop any IBS symptoms. CONCLUSIONS: This is the first report of the development of PI-IBS after T. britovi. Consequently, IBS can be considered as a secondary syndrome induced by trichinellosis.
