Inflammatory Bowel Disease II: Crohn's Disease

354
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

298
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

397
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 V: Surgical Management

195
Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

526
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

174
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.

Summary

Corticosteroid use in inflammatory bowel disease (IBD) can lead to avascular necrosis (AVN). Other risk factors like arthropathy also contribute to AVN development in IBD patients.

Area of Science:

  • Gastroenterology
  • Rheumatology
  • Endocrinology

Background:

  • Avascular necrosis (AVN) is a recognized adverse event linked to corticosteroid (CS) therapy.
  • Inflammatory bowel disease (IBD) management frequently involves CS for remission induction.
  • Understanding the clinical characteristics and outcomes of AVN in IBD patients is crucial.

Purpose of the Study:

  • To investigate the clinical features and outcomes of avascular necrosis (AVN) in patients with inflammatory bowel disease (IBD).
  • To identify risk factors associated with AVN development in the IBD population.

Main Methods:

  • Retrospective, single-center, case-control study design.
  • Inclusion of IBD patients diagnosed with AVN between 1976 and 2009, matched with IBD controls without AVN.
  • Conditional logistic regression analysis to assess risk factors for AVN, controlling for age and IBD diagnosis date.

Main Results:

  • Eighty-five IBD patients with AVN were matched with 163 controls.
  • AVN was diagnosed a median of 12.2 years post-IBD diagnosis; 10% of AVN patients had no CS exposure.
  • Significant AVN risk factors included arthropathy history and estrogen use (Crohn's disease), and CS use, osteoporosis, and arthropathy history (ulcerative colitis).

Conclusions:

  • Most IBD patients with AVN experienced multifocal involvement.
  • While corticosteroid use was common, other risk factors such as arthropathy were also prevalent.
  • These findings highlight the multifactorial nature of AVN in IBD patients.
