Correlation between anxiety-depression status and cytokines in diarrhea-predominant irritable bowel syndrome

The aim of this study was to investigate the correlation between anxiety-depression status and cytokines in diarrhea-predominant irritable bowel syndrome (IBS-D). IBS-D patients were divided into an anxiety-depression IBS-D group and a non-anxiety-depression IBS-D group. Patients without IBS, anxiety or depression were selected as the control group. Scoring was performed using the self-rating anxiety scale (SAS) and self-rating depression scale (SDS). Levels of IL-1β and IL-10 in the blood and sigmoid colon mucosa were detected, and the proportions of IL-1β- and IL-10-positive cells in the sigmoid colon mucosa were determined. The results demonstrated that the SDS and SAS scores in the IBS-D group were significantly higher than those in the control group (P
