Microscopic colitis (MC) and irritable bowel syndrome (IBS) are both gastrointestinal disorders with female predominance that affect well-being. Autoantibodies against gonadotropin-releasing hormone (GnRH) have recently been detected in IBS patients. The purpose of this study was to compare gastrointestinal symptoms and well-being in MC female outpatients, with or without coexisting IBS-like symptoms, and to examine the prevalence of GnRH antibodies in these patients. Women with biopsy-verified MC, at any outpatient clinic of the Departments of Gastroenterology, Skåne, between 2002 and 2010 were invited to participate in the study. The questionnaires Gastrointestinal Symptom Rating Scale (GSRS), Psychological General Well-being Index (PGWB), Visual Analogue Scale for Irritable Bowel Syndrome (VAS-IBS), and Rome III were answered and blood samples collected. Autoantibodies (IgG, IgA, and IgM) against GnRH and GnRH-R (extracellular peptide of receptor) were determined by an enzyme-linked immunosorbent assay. Altogether, 158 (66%) of 240 invited patients with MC were recruited to the study. Of these, 133 (55%) patients also accepted to provide blood samples. Patients with IBS-like symptoms (55%) experienced more symptoms and worse psychological well-being in all dimensions in GSRS and PGWB, and in all symptoms but constipation in VAS-IBS compared to patients without IBS symptoms. Only a minority of patients expressed antibodies against GnRH or GnRH-R, which did not differ between groups. MC patients fulfilling criteria for IBS experience more gastrointestinal symptoms and worse psychological well-being than those who do not. Autoantibodies against GnRH or GnRH-R are not frequently observed in MC patients.
