ABSTRACT
Irritable bowel syndrome (IBS) is a common intestinal disorder. The pathophysiology of IBS may involve an altered intestinal microbiota. Recent studies have shown that alterations in microRNA (miRNA) levels have affected IBS and its subtypes. We aimed to compare both the count of Coliform and serum level of miRNA-199b between patients with IBS and healthy controls and to find the relationship between the Coliform and miRNAs in patients with IBS. Patients with IBS were classified into three subgroups based on their predominant bowel pattern as defined by Rome III criteria. Quantitative culture of Coliform and determination of serum miRNA-199b expression level by quantitative real-time PCR in IBS group versus healthy controls were performed. There was a significant increase in the count of Coliform in patients with IBS and its different subtypes when compared with healthy controls. There was a significant decrease of serum miR-199b expression level in patients with IBS and its different subtypes when compared with healthy controls with the highest level (1.9 ± 0.53 log scale) in healthy controls and lowest one (0.71 ± 0.27 log scale) in IBS with diarrhea (IBS-D) subtype. Moreover, there was a negative correlation between the count of Coliform and the serum miRNA-199b expression level in IBS. This study reported that there was a significant increase in the count of Coliform and a decrease in the serum miRNA-199b expression level. In addition, there was a negative correlation between them in patients with IBS and its different subtypes when compared with healthy controls. © 2016 IUBMB Life, 68(5)335-342, 2016.
