Abstract:
A subset of celiac disease (CD) patients is, or becomes, refractory to a gluten-free diet with persistent malabsorption and intestinal villous atrophy (VA). The most common cause of this condition is inadvertent gluten exposure but concomitant diseases and alternative diagnoses resulting in VA should also be considered and excluded. Differential diagnosis between inadvertent gluten exposure, slow responsive disease, non-responsive CD, and refractory celiac disease (RCD) is frequently difficult. This review will summarize the current knowledge on epidemiology, pathogenesis, and the diagnostic armamentarium of RCD, as well as a review of past and current therapies.

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.

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, 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...
