Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

620
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...

Inflammatory Bowel Disease II: Crohn's Disease

932
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 IV: Pharmacological Management

452
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.

Inflammatory Bowel Disease I: Ulcerative Colitis

876
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...

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents01:29

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents

469
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

735
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...

Area of Science:

  • Gastroenterology and Immunology

Background:

  • Inflammatory bowel disease (IBD) is a complex gastrointestinal disorder characterized by chronic inflammation, oxidative stress, and immune dysregulation.
  • The etiology of IBD is multifactorial, involving genetics, immune responses, gut microbiota, and environmental factors, with a rising global prevalence.
  • Undernutrition is common in IBD patients, prompting research into the role of micronutrients like selenium (Se) in disease modulation.

Purpose of the Study:

  • To comprehensively review the current evidence linking selenium status to inflammatory bowel disease.
  • To elucidate the biological mechanisms through which selenium influences IBD pathogenesis.
  • To introduce selenium nanoparticles as a potential therapeutic strategy for IBD management.

Main Methods:

  • Systematic review of epidemiological studies and experimental findings on selenium and IBD.
  • Analysis of selenium's physiological functions, including antioxidant, anti-inflammatory, and immunomodulatory effects.
  • Exploration of selenium's impact on gut microbial composition and diversity.

Main Results:

  • Selenium is an essential trace element with significant antioxidant and anti-inflammatory properties relevant to IBD.
  • Evidence suggests a relationship between selenium status and IBD activity, mediated by its effects on oxidative stress and immune responses.
  • Selenium influences the gut microbiome, potentially impacting IBD pathogenesis.

Conclusions:

  • Selenium status is an important factor in inflammatory bowel disease.
  • Selenium's multifaceted biological activities offer therapeutic potential for IBD.
  • Selenium nanoparticles represent a promising novel approach for IBD treatment.
