Objectives:
Oral extraintestinal manifestations (OEIMs) of inflammatory bowel disease (IBD) may impact IBD treatment. The aims of this study were to: (1) determine which OEIMs are most prevalent among patients with IBD, (2) investigate the presence of a temporal association between GI luminal disease activity and OEIMs, and (3) determine how often changes in therapeutic management of IBD are needed in the presence of OEIMs.
Study Design:
A retrospective cohort study was performed for adult patients with IBD evaluated between January 2017 and November 2021 with at least 1 oral complaint. Demographic data were collected from the charts of these patients. Kruskal-Wallis test for continuous measures and Fisher's Exact test for categorical measures were used.
Results:
A total of 116 patients with IBD who had presented with at least 1 oral finding during the study time period were identified. Aphthous ulcers were the most common oral presentation in both Crohn's disease (CD) (85.1%) and ulcerative colitis (UC) (75.0%). OEIMs were associated with CD activity in the small intestine (P = .004) and colon (P < .001). UC pancolitis was associated with OEIMs (P = .002). In 32.7% of patients, OEIMs led to either an increase in dose or frequency of IBD therapy. In an additional 16.4% of patients, new systemic agents were started because of the OEIMs.
Conclusions:
This study provides evidence that patients with IBD may develop OEIMs synchronous with IBD flares and may require escalation of IBD therapy when OEIMs occur.

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...
01:17Chronic Bowel Disorders: Introduction
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...
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...

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...
