Inflammatory Bowel Disease II: Crohn's Disease01:30

Inflammatory Bowel Disease II: Crohn's Disease

383
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

324
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...

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

541
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 III: Diagnostic Studies and Management I-Nutritional Therapy

420
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 IV: Pharmacological Management

189
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 Ulcerative Colitis in IBD01:29

Drugs for Treatment of Ulcerative Colitis in IBD

237
Ulcerative colitis is a chronic inflammatory condition primarily affecting the colon and rectum. The primary drugs used in the treatment of ulcerative colitis are aminosalicylates. They exhibit anti-inflammatory and immunosuppressive properties. They modulate inflammatory mediators and inhibit the activity of nuclear factor κB (NF-κB). Aminosalicylates also reduce inflammation by inhibiting prostaglandin and leukotriene production and decreasing neutrophil chemotaxis and superoxide...

Summary

Eosinophilic mesenteric vasculitis (EMV) can mimic Crohn's Disease (CD) but requires specific diagnosis. This rare condition may necessitate surgery if standard inflammatory bowel disease treatments fail, highlighting diagnostic challenges.

Area of Science:

  • Gastroenterology
  • Pathology
  • Immunology

Background:

  • Inflammatory bowel disease (IBD), encompassing Crohn's Disease (CD) and ulcerative colitis, is a chronic gastrointestinal inflammatory condition.
  • Treatment strategies for IBD range from medical to surgical interventions, with biologics reducing surgical necessity.
  • Eosinophilic mesenteric vasculitis (EMV) is a rare vasculitis that can present similarly to IBD, posing diagnostic difficulties.

Purpose of the Study:

  • To highlight the diagnostic challenges of eosinophilic mesenteric vasculitis (EMV) that mimics inflammatory bowel disease (IBD).
  • To present a case study illustrating the misdiagnosis and eventual correct diagnosis of EMV in a patient initially presenting with symptoms suggestive of Crohn's Disease (CD).

Main Methods:

  • Case report of a 15-year-old female with a history of autoimmune hemolytic anemia.
  • Clinical presentation initially suggestive of CD, including colonic stricture.
  • Evaluation of treatment response to standard IBD therapies, including biologic agents.

Main Results:

  • The patient exhibited a lack of clinical remission and persistent colonic stricture despite receiving biologic therapy.
  • Diagnosis of EMV was confirmed, distinguishing it from CD due to its unique response patterns to therapies.
  • The condition ultimately led to bowel obstruction, necessitating surgical resection.

Conclusions:

  • Eosinophilic mesenteric vasculitis (EMV) presents a diagnostic challenge due to its mimicry of Crohn's Disease (CD).
  • Full-thickness biopsies are crucial for diagnosing EMV, which requires specific management distinct from typical IBD treatments.
  • Delayed or incorrect diagnosis of EMV can lead to severe complications such as bowel obstruction requiring surgical intervention.
