Tumour necrosis factor alpha (TNF-alpha) is overexpressed in segmental colitis associated with diverticula (SCAD), indicating its role in SCAD pathogenesis. This finding mirrors its involvement in other inflammatory bowel diseases.
Area of Science:
- Gastroenterology
- Immunology
- Pathology
Background:
- Segmental colitis associated with diverticula (SCAD) pathogenesis remains unclear.
- Tumour necrosis factor alpha (TNF-alpha) is implicated in inflammatory bowel disease (IBD) pathogenesis.
Purpose of the Study:
- To investigate TNF-alpha levels in patients with SCAD.
- To compare TNF-alpha expression in SCAD patients with controls.
Main Methods:
- Post hoc analysis of a prospective multicenter study.
- Histological analysis of tissue samples from 13 SCAD patients.
- Immunohistochemical staining for TNF-alpha.
- Comparison with matched irritable bowel syndrome (IBS) controls.
Main Results:
- Overexpression of TNF-alpha was detected in all SCAD patients (38.6 +/- 10.4%).
- Elevated TNF-alpha correlated with high histological scores and neutrophil counts.
- SCAD patients showed significantly higher TNF-alpha levels than IBS controls.
Conclusions:
- TNF-alpha activity is implicated in the pathogenesis of SCAD.
- SCAD pathogenesis shares similarities with Crohn's disease and ulcerative colitis.
- Targeting TNF-alpha may be a therapeutic strategy for SCAD.

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 I: Introduction
Inflammatory Bowel Disease II: Crohn's Disease
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 transmural...
