Purpose:
After the COVID-19 pandemic, many challenges arose regarding the impact of this disease on people with ulcerative colitis. The aims of this study were to estimate the prevalence, severity, and death consequences of COVID-19 in patients with ulcerative colitis using a systematic review and meta-analysis.
Methods:
This study was conducted using a systematic review and meta-analysis method in the field of prevalence, severity, and clinical consequences of COVID-19 in people with ulcerative colitis worldwide. The search was conducted in international scientific databases, such as Web of Science, PubMed, Scopus, Cochrane Library, and Google Scholar, from the beginning of 2020 to October 2023. The quality of the eligible studies was assessed using the Strobe and Newcastle Ottawa checklists. The data were analyzed using a fixed-effects model in the meta-analysis. Subgroup analysis and meta-regression were performed using STATA version 17.
Results:
Nineteen studies with a sample size of 224,520 patients were included in this meta-analysis. The results showed that, in COVID-19 patients with ulcerative colitis, the prevalence of hospitalization, death, COVID-19 severity, and mortality rate in severe patients was 54% (95% CI, 27-80%), 10% (95% CI, 4-16%), 20% (95% CI, 8-34%), 63% (95% CI, 46-80%), respectively. In comparison with the general population, the odds ratio (OR) of hospitalization in patients due to COVID-19 was OR = 1.28 (95% CI, 1.19-1.38, P < 0.001), and the chance of severe COVID-19 was OR = 1.30 (95% CI, 1.22-1.53, P < 0.001).
Conclusion:
The probability of contracting the severe type of COVID-19 and hospitalization in patients with ulcerative colitis was higher than in the general population.

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...
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...

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...
