Irritable Bowel Syndrome II: Clinical Features and Diagnostic Evaluation
Irritable Bowel Syndrome (IBS) is classified into subtypes based on the predominant bowel habits as determined by the Bristol Stool Form Scale (BSFS). The subtypes are:

Irritable Bowel Syndrome I: Introduction

768
Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:
Altered...

Inflammatory Bowel Disease II: Crohn's Disease

737
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 III: Diagnostic Studies and Management I-Nutritional Therapy

535
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

666
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 I: Ulcerative Colitis

682
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...

Summary

Acute infectious gastroenteritis (AGE) significantly increases the risk of developing post-infectious irritable bowel syndrome (PI-IBS), especially in females. Campylobacter jejuni infection poses the highest risk for PI-IBS development.

Area of Science:

  • Gastroenterology
  • Infectious Diseases
  • Epidemiology

Background:

  • Post-infectious irritable bowel syndrome (PI-IBS) lacks comprehensive risk factor data.
  • Acute infectious gastroenteritis (AGE) is a known trigger for PI-IBS.

Purpose of the Study:

  • To identify risk factors for developing PI-IBS after an acute infectious gastroenteritis (AGE) episode.
  • To compare PI-IBS risk between AGE and acute upper respiratory tract infection (URTI).

Main Methods:

  • Prospective study comparing AGE patients with a URTI control group.
  • Patients evaluated using Rome III criteria and Bristol Stool Form Scale at 6 months.
  • Laboratory-confirmed etiological agents for AGE cases.

Main Results:

  • PI-IBS prevalence was significantly higher in AGE patients (RR=4.16) compared to URTI controls.
  • Female sex was a significant risk factor for PI-IBS (79% developed PI-IBS).
  • Campylobacter jejuni AGE cases showed the highest PI-IBS risk (RR=1.2).

Conclusions:

  • AGE is a significant risk factor for developing PI-IBS.
  • Female sex and Campylobacter jejuni infection are key risk factors for PI-IBS.
  • Further research is needed to elucidate PI-IBS pathogenesis and prevention strategies.
