Abstract

Inflammatory bowel disease comprising Crohn's disease and ulcerative colitis presents with periods of flares and remission. Many reports have identified different dysregulated miRNAs in patients with IBD. Finding new biomarkers in IBD patients can help to launch a novel non-invasive approach for diagnosis and prognosis for patients with UC and CD. This study aimed to evaluate the plasma expression pattern of the miRNAs panel in IBD patients compared to healthy individuals. 73 plasma samples were included; 58 patients with IBD (33 individuals in flare and 25 in remission phase) and 15 healthy controls were enrolled in the study. The miRNA expression was measured by qRT-PCR using miScript SYBR Green PCR Kit (QIAGEN). Our results showed the expression level of miR-16-5P was significantly increased in the active phase compared to the inactive phase (P=0.0138) and in CD patients compared to UC patients (P=0.0216). There was a significant difference in the expression of miR-29a in Crohn's patients compared to healthy subjects (P=0.04). Measuring the expression of mir-106a; a significant increase was observed compared to healthy individuals (P=0.03) and patients with CD (P=0.0143) in proportion of UC patients’ group. The miR-126 expression significantly increased in patients with active disease compared to patients in the inactive phase (P=0.0413) and healthy controls (P=0.0492). This study showed evidence for differential expression levels of plasma panel of miR-16, miR-29a, miR-106a, and miR-126 in IBD patients compare to healthy individuals. We illustrate that miRNAs in plasma correlate with disease activity and can be used as a practical and non-invasive biomarker for early diagnosis and monitoring of the treatment protocol.
