Background:
Great efforts by the scientific community are rapidly expanding the evidence on the clinical interplay between Covid-19 and inflammatory bowel disease (IBD).
Aims:
We performed a systematic review of the literature on published Covid-19 cases occurring in patients with IBD.
Methods:
PubMed Central/Medline and Embase were systemically searched for records up to May 31, 2020.
Results:
13 cohort studies and 5 single case reports were included in the qualitative synthesis. A cumulative number of approximately 800 patients with IBD and Covid-19 were identified. The case fatality rate ranged from 0% to 20.0%. Overall, immunomodulators and biologics were not associated with higher risk of Covid-19 or with negative outcomes, while the use of systemic corticosteroids was related to worse prognosis in some studies.
Conclusions:
This systematic review highlighted two main points that may help clinicians dealing with IBD in reassuring their patients: (1) patients with IBD do not seem to be at higher risk of being infected by SARS-COV-2 than the general population; (2) in case of Covid-19, treatment with immunomodulators or biologics is not associated with worse prognosis, while systemic steroids are suspected to be potentially detrimental, even if more data are needed to confirm this point.

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...
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...
