Description
Summary:Background and aim Autoimmune disorders (AID) have been shown to be associated with chronic antibiotic-refractory pouchitis (CARP). The role of anti-microsomal antibodies in ileal pouch disorders has not been investigated. The aims of the study were to investigate the prevalence of positive anti-microsomal antibody in symptomatic patients with ileal pouches and to investigate its clinical implications. Methods A total of 118 consecutive symptomatic patients with ileal pouches were included between January and October 2010. Anti-microsomal antibodies were measured at the time of presentation. Demographic, clinical, and laboratory characteristics were compared between patients with positive and negative anti-microsomal antibody. Results There were 14 patients (11.9%) with positive serum anti-microsomal antibody. The mean age of patients in the antibody positive and negative groups were 41.8 ± 14.4 and 42.0 ± 14.0 years, respectively ( p  = 0.189). All 14 patients in the antibody positive group (100%) had some form of AID, as compared to 20 patients (19.2%) in the antibody negative group ( p
