Insights

Lactobacillus GG supplementation improved clinical symptoms and gut permeability in children with Crohn's disease. This pilot study suggests potential benefits for gut barrier function in pediatric inflammatory bowel disease.

Area of Science:

  • Gastroenterology
  • Microbiology
  • Pediatrics

Background:

  • Lactobacillus GG is a probiotic bacterium known for gut colonization and treating gastrointestinal issues.
  • Increased intestinal permeability is a characteristic of several gastrointestinal conditions.

Purpose of the Study:

  • To investigate the efficacy of Lactobacillus GG in children diagnosed with Crohn's disease.

Main Methods:

  • An open-label pilot study involved four children with mild to moderate Crohn's disease.
  • Lactobacillus GG (10(10) CFU) was administered twice daily for six months.
  • Intestinal permeability and clinical activity were assessed using specific tests and indices.

Main Results:

  • Significant clinical improvement was observed within one week of Lactobacillus GG administration, sustained throughout the study.
  • Pediatric Crohn's disease activity index scores decreased by a median of 73% at four weeks.
  • Intestinal permeability showed a parallel improvement trend.

Conclusions:

  • Lactobacillus GG shows promise in enhancing gut barrier function and clinical status for pediatric Crohn's disease patients.
  • Further randomized, double-blind, placebo-controlled trials are recommended for definitive efficacy assessment.

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

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 (COX-2),...

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 colonic...

Inflammatory Bowel Disease III: Crohn's Disease

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...
