What was done
This narrative review summarizes the immunological role of the gastrointestinal tract and examines the clinical, immunological, and histopathological features of rare inflammatory bowel diseases caused by monogenic primary immunodeficiencies.
What was found
The abstract provides no empirical data or numerical findings. It qualitatively describes how single-gene mutations affecting mucosal defense lead to autoimmune, infectious, or inflammatory bowel phenotypes presenting with diarrhea, malabsorption, melena, and growth failure, and notes that histological analysis contributes to differential diagnosis.
Why it matters
It emphasizes the need to consider monogenic primary immunodeficiencies during the histopathological differential diagnosis of atypical or severe inflammatory bowel diseases.
Limits
The abstract reports no original study population, sample size, or quantitative metrics, serving only as a descriptive narrative review.
