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

1.1K
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 III: Crohn's Disease

25
Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...

Inflammatory Bowel Disease I: Introduction

34
Inflammatory bowel disease is a group of chronic disorders marked by recurrent inflammation of the gastrointestinal tract due to an abnormal immune response against gut microflora. This leads to tissue damage. The two main forms are Crohn’s disease and ulcerative colitis.Crohn’s DiseaseCrohn’s disease is a relapsing inflammatory disorder that can affect any part of the GI tract, from the mouth to the anus. It involves all layers of the bowel wall (transmural) and shows...

Inflammatory Bowel Disease IV: Pharmacological Management

1.1K
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 II: Ulcerative Colitis

25
Ulcerative colitis is a chronic inflammatory disorder of the colon characterized by continuous mucosal inflammation that typically begins in the rectum and extends proximally in a uniform pattern. Its pathogenesis involves a complex interplay of genetic predisposition, immune dysregulation, and environmental influences. These factors converge to impair the colon’s epithelial defenses and promote an exaggerated inflammatory response against luminal contents.Breakdown of the Mucosal...

Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids01:21

Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids

686
Glucocorticoids, a class of anti-inflammatory drugs, are pivotal in treating moderate to severe Crohn's disease by inducing remission. They exhibit their anti-inflammatory action by inhibiting the production of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1, and chemokines like IL-8. In addition, they reduce the expression of inflammatory cell adhesion molecules and inhibit gene transcription of nitric oxide synthase, phospholipase A2, cyclooxygenase-2...
