Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

936
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 II: Crohn's Disease

1.3K
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

1.2K
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...

Area of Science:

  • Oncology
  • Gastroenterology
  • Molecular Biology
  • Bioinformatics

Background:

  • Colorectal cancer (CRC) poses significant health risks, with inflammatory bowel disease (IBD) being a known risk factor.
  • Understanding shared molecular mechanisms between IBD and CRC is crucial for developing effective early detection and prevention strategies.

Purpose of the Study:

  • To elucidate shared molecular mechanisms between IBD and CRC.
  • To identify key proteins and regulatory pathways involved in colorectal carcinogenesis driven by inflammation.

Main Methods:

  • Proteomic analysis of UK Biobank data using Olink proximity extension assay for seven CRC-associated proteins.
  • Comparison of protein expression levels in CRC and IBD cases versus controls.
  • Construction of multilayer interaction networks (protein-protein, protein-metabolite, transcription factor-protein) using OmicsNet.
  • Validation of findings using the Colonomics transcriptomic dataset.

Main Results:

  • Seven CRC-associated proteins were analyzed; six were elevated in both CRC and IBD.
  • Network analysis highlighted AHCY and LCN2 as central hubs connecting inflammatory and metabolic pathways.
  • NF-κB and GATA2 were identified as recurrent transcriptional regulators.
  • Colonomics data validated the upregulation of AHCY, LCN2, and SELE in CRC tissues.

Conclusions:

  • A shared molecular framework exists between IBD and CRC.
  • Inflammation plays a pivotal role as a driver in colorectal carcinogenesis.
  • The findings provide insights into potential therapeutic targets and biomarkers for CRC prevention and early detection in IBD patients.
