Abstract

Objective To explore the depression and anxiety status of patients with refractory irritable bowel syndrome (IBS)and its subtypes. Methods In this large sample, multi-center, prospective survey(Registration number in Chinese Clinical Trial Registry: ChiCTR-TRC-12001969), the patients who conformed to the Rome III criteria for IBS were recruited from the department of gastroenterology of three hospitals in Guangdong province from June 2012 to September 2012. And 100 healthy subjects from the examination center of hospitals were recruited at the same time. The 17-item Hamilton Depression Rating Scale(HAMD) and the 14-item Hamilton Anxiety Rating Scale(HAMA) were used to analyze the depression and anxiety, respectively. Results 9802 patients were collected from department of gastroenterology, and a total of 1128(11.5%) patients were diagnosed as IBS. 601 of questionnaires were collected, including 142 (23.6%)of refractory IBS and 459 (76.4%) of non-refractory IBS.The incidences of depression, anxiety, depression and anxiety and the HAMD, HAMA scores were higher in refractory IBS group than those in the non-refractory IBS and control group, ((66.2% vs 23.3% vs 9.0%), P 0.05). However, the HAMA scores of IBS-D and IBS-M were higher than that of IBS-U((10.10±5.03) vs(7.55±3.22), P<0.05; (12.08±6.89) vs(7.55±3.22), P<0.05). Conclusion The high incidences of depression, anxiety and depression and anxiety, and the serious degrees of depression and anxiety existed in the patients with refractory IBS.
