Effects of Vitamin D on Gut Microbiota, Intestinal Barrier in IBS-D Patients

Diarrhea-predominant Irritable Bowel Syndrome Clinical Trial

Official title:
Effects of Vitamin D on Gut Microbiota, Intestinal Barrier in Patients With Diarrhea-predominant Irritable Bowel Syndrome

Clinical Trial Summary

Irritable bowel syndrome (IBS) is a common functional gastrointestinal disease. Evidence suggests that the concentration of serum VD is decreased in IBS patients, particularly in IBS-D. After giving a supplementation of VD, some symptoms of these patients were relieved to a certain degree. However, the specific mechanism still remains unclear.

Clinical Trial Description

Irritable bowel syndrome (IBS) is a common functional gastrointestinal disease, which is due to the gut microbiota disturbances, intestinal mucosal barrier dysfunction, and brain-gut axis dysfunction. Vitamin D (VD), a fat-soluble vitamin, has been found to be associated with gut microbiota, intestinal mucosal barrier and NLRP3 in inflammatory bowel disease, nonalcoholic fatty liver disease and other diseases. The concentration of serum VD is decreased in IBS patients, particularly in IBS-D. And the symptoms of IBS patients seems to be connected with the level of serum VD. After giving a supplementation of VD, some symptoms of these patients were relieved to a certain degree. However, the specific mechanism still remains unclear.We designed a study to figure out the effects of serum VD on gut microbiota, intestinal mucosal barrier and in patients with IBS-D. ;
