Introduction:
controversial data have been reported on the potential association between celiac disease (CeD) and inflammatory bowel disease (IBD).
Objective:
to study the prevalence of CeD in patients newly diagnosed cases with IBD.
Methods:
an observational, retrospective study was performed in patients with newly diagnosed IBD who were screened for CeD by anti-tissue transglutaminase antibodies (anti-tTG) measurements and an endoscopic duodenal biopsy. No patients had received corticosteroids, immunosuppressants or biologic drugs within the three months prior to gastroscopy. In the presence of Marsh 1, other causes were ruled out. CeD was diagnosed in patients positive for anti-tTG, compatible duodenal biopsy findings and a good response to a gluten-free diet.
Results:
a total of 163 patients were screened for CeD. Of these, six (3.7%) were positive for anti-tTG and four were diagnosed with CeD (three had ulcerative colitis, one had Crohn's disease). All patients with both CeD and IBD had normal IgA levels, positive anti-tTG and CeD genetic markers.
Conclusions:
the prevalence of CeD in our patients with IBD was higher than that reported in the literature for other series of patients with IBD. A combination of anti-tTG testing and CeD genetics may screen patients for CeD in this population of patients with IBD.

01:30Inflammatory 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...
01:27Inflammatory Bowel Disease I: Ulcerative Colitis
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...

Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

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...
