Abstract

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.
