Purpose:
To explore health outcomes of patients with ulcerative colitis (UC) and associated ocular inflammatory disease, compared to those of matched patients with UC without associated ocular inflammatory disease.
Design:
Retrospective case-control study.
Methods:
An aggregated electronic health records research network, TriNetX (Cambridge, MA, USA), was used to identify patients diagnosed with UC stratified by the presence or absence of ocular inflammatory disease with at least one year of follow-up. Propensity score matching (PSM) was performed to control for baseline demographics and medical comorbidities.
Main Outcome Measures:
Rates and relative risk (RR) of developing various forms of intestinal complications, extraintestinal morbidities, rheumatologic disease, cardiovascular disease, and death.
Results:
Patients with UC with associated ocular inflammatory disease showed greater risk of undergoing total colectomy, as well as acquiring Clostridioides difficile and CMV colitis. They also demonstrated a greater risk of developing MASLD, vitamin D deficiency, iron deficiency anaemia, UC-related dermatological disease, osteoporosis, and sepsis. These individuals were more likely to carry rheumatologic diagnoses, including ankylosing spondylitis, psoriatic, rheumatoid, enteropathic, reactive, and inflammatory arthritis. There was an elevated risk of stroke, myocardial infarction, and VTE in this cohort as well. There was no significant difference in risks of colorectal cancer, primary sclerosing cholangitis, toxic megacolon, non-radiographic axial spondyloarthritis, or mortality between the cohorts.
Conclusions:
Patients with UC with ocular inflammatory disease have an increased risk of intestinal complications, extraintestinal morbidity, rheumatologic disease, and cardiovascular complications when compared to those without.

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...
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...

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...
