    Abstract:
    BACKGROUND AND OBJECTIVE: The glucagon-like peptide-1 (GLP-1) analog, ROSE-010, plays a critical role in alleviating abdominal pain in patients with irritable bowel syndrome (IBS); however, the underling mechanism is unclear. In the present study, we determined the serum GLP-1 level in patients with constipation-predominant IBS (IBS-C). The relationship between GLP-1 and abdominal pain was investigated. In addition, the expression of the GLP-1 receptor in the colon was determined. METHODS: Rectosigmoid biopsies were gathered from 38 patients with IBS-C who met the Rome III criteria, and 22 healthy controls. Abdominal pain was quantified by a validated questionnaire. Serum GLP-1 was measured by ELISA and correlated with abdominal pain scores. The presence of the GLP-1 receptor in the colonic mucosa was assessed by immunohistochemistry. RESULTS: Serum GLP-1 was substantially decreased in patients with IBS-C. Decreased serum GLP-1 had a negative correlation with the abdominal pain scores. Biopsies from patients with IBS-C revealed a significant down-regulation of the GLP-1 receptor in colonic mucosa compared with control subjects. CONCLUSIONS: Decreased serum GLP-1 correlates with abdominal pain in patients with IBS-C. Decreased expression of GLP-1 and GLP-1 receptor may be the basis for alleviation of abdominal pain in patients with IBS-C by ROSE-010.
