Insights

Acute gastroenteritis (AGE) in children can lead to post-infection irritable bowel syndrome (PI-IBS). Rotavirus caused severe AGE, while parasitic and bacterial infections showed higher CRP levels, correlating with PI-IBS development.

Area of Science:

  • Pediatric Gastroenterology
  • Infectious Diseases
  • Clinical Research

Background:

  • Acute gastroenteritis (AGE) is a leading cause of hospitalization and mortality in children globally.
  • AGE is recognized as a risk factor for developing post-infection irritable bowel syndrome (PI-IBS).
  • Understanding the link between AGE etiology and PI-IBS is crucial for pediatric health.

Purpose of the Study:

  • To correlate the clinical severity of AGE with specific infectious agents.
  • To investigate the occurrence of PI-IBS in North Lebanese children and adolescents following AGE.
  • To identify potential risk factors for PI-IBS development after AGE.

Main Methods:

  • 219 pediatric patients (4-15 years) with gastrointestinal complaints were enrolled.
  • Stool samples were analyzed for microbiological agents; AGE severity was scored using the Vesikari scale.
  • Patients were monitored for PI-IBS development using Rome IV criteria and Bristol Stool Scale.

Main Results:

  • Viral pathogens were most common (26.9%), with rotavirus linked to severe AGE (25.1%).
  • Parasitic and bacterial AGE cases showed elevated C-reactive protein (CRP) levels (p=0.009).
  • 13.24% of patients developed PI-IBS, predominantly with mixed bowel habits (IBS-M).

Conclusions:

  • This study offers preliminary insights into PI-IBS development in Lebanese pediatric populations.
  • Specific AGE etiologies may influence PI-IBS risk and severity.
  • Further research is needed to elucidate PI-IBS pathogenesis and prevention strategies.

Irritable Bowel Syndrome I: Introduction

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...

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

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 II: Crohn's Disease

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

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 I: Ulcerative Colitis

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...
