Abstract:
Inflammatory bowel disease (IBD), classified primarily between Crohn's disease and ulcerative colitis, is a collection of chronic gastrointestinal inflammatory conditions that cause multiple complications because of systemic alterations in the immune response. One major player is microRNA (miRNA), which is found to be associated with multiple pathways in mediating inflammation, especially those of a chronic nature in IBD, as well as irritable bowel syndrome. Although there have been studies linking miRNA alterations in IBD, even differentiating Crohn's disease and ulcerative colitis, this review focuses mainly on how miRNAs cause and mechanistically influence the pathologic complications of IBD. In addition to its role in the well-known progression towards colorectal cancer, we also emphasize how miRNA manifests the many extraintestinal complications in IBD such as cardiovascular diseases; neuropsychiatric conditions such as depression and anxiety disorders; and others, including various musculoskeletal, dermatologic, ocular, and hepatobiliary complications. We conclude through a description of its potential use in bettering diagnostics and the future treatment of IBD and its systemic symptoms.
Insights
MicroRNAs (miRNAs) significantly influence inflammatory bowel disease (IBD) complications. This review details how miRNAs drive IBD pathology, including colorectal cancer and extraintestinal issues, and their diagnostic and therapeutic potential.
Area of Science:
- Gastroenterology
- Molecular Biology
- Immunology
Background:
- Inflammatory bowel disease (IBD), encompassing Crohn's disease and ulcerative colitis, involves chronic gastrointestinal inflammation.
- Systemic immune alterations in IBD contribute to numerous complications.
- MicroRNAs (miRNAs) are implicated in inflammatory pathways relevant to IBD and irritable bowel syndrome.
Purpose of the Study:
- To review the mechanistic role of miRNAs in the pathogenesis of IBD complications.
- To explore the involvement of miRNAs in both intestinal and extraintestinal manifestations of IBD.
- To discuss the potential of miRNAs in IBD diagnostics and therapeutics.
Main Methods:
- Literature review focusing on miRNA's role in IBD.
- Analysis of studies linking miRNA alterations to IBD pathology.
- Synthesis of evidence on miRNA-mediated complications.
Main Results:
- miRNAs are key mediators of chronic inflammation in IBD.
- miRNA dysregulation contributes to colorectal cancer development in IBD patients.
- miRNAs are implicated in extraintestinal complications, including cardiovascular, neuropsychiatric, musculoskeletal, dermatologic, ocular, and hepatobiliary conditions.
Conclusions:
- miRNAs are central to IBD pathogenesis and its diverse complications.
- Understanding miRNA mechanisms offers novel diagnostic and therapeutic strategies for IBD.
- Targeting miRNAs may improve management of both intestinal and systemic IBD symptoms.

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
Chronic Bowel Disorders: Introduction
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...
