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

Introduction
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

Introduction
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

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
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: Introduction01:17

Chronic Bowel Disorders: Introduction

Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
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...

Inflammatory Bowel Disease IV: Pharmacological Management

Upon diagnosis, managing Inflammatory Bowel Disease (IBD) involves addressing several crucial aspects. The primary goals include resting the bowel, correcting malnutrition, and providing symptomatic relief. Resting the bowel may consist of medications to reduce inflammation and promote healing. Correcting malnutrition is essential, often requiring dietary adjustments and nutritional supplements. Symptomatic relief aims to ease pain, diarrhea, and other discomforts in IBD.

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF

Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...
