Special Issue Information

Dear Colleagues,

The connection between inflammatory bowel disease (IBD) and infections was established soon after the classification of both Crohn’s disease ( CD) and  ulcerative colitis (UC). It is now clear that infections play an important role in pathogenesis, clinical course, and disease exacerbations during IBD. Moreover, the disease itself predisposes patients to various infections, and the infection risk rises even higher during therapy, as the most commonly used medications induce immunomodulation and inhibition. Hence, various drugs have been shown to expose patients to specific infectious agents (e.g., tuberculosis, herpes zoster). Furthermore, immunomodulation affects response to vaccinations, thus further increasing patients’ exposure to infections. As a consequence, national and international guidelines support screening tests, pretreatment vaccinations, and prophylactic therapy for specific cases. Gathering new information on any of these subjects may lead to a better understanding of the mechanism and risk factors and may help in risk stratification and the development of new therapeutic and prophylactic approaches.

Background: Crohn’s disease (CD) and ulcerative colitis (UC) are chronic, immune-mediated inflammatory bowel diseases (IBD) affecting millions of people worldwide. IBD therapies, designed for continuous immune suppression, often render patients more susceptible to infections. The effect of the immune suppression on the risk of coronavirus disease-19 (COVID-19) is not fully determined yet. Objective: To describe COVID-19 characteristics and outcomes and to evaluate the association between IBD phenotypes, infection outcomes and immunomodulatory therapies. Methods: In this multi-center study, we prospectively followed IBD patients with proven COVID-19. De-identified data from medical charts were collected including age, gender, IBD type, IBD clinical activity, IBD treatments, comorbidities, symptoms and outcomes of COVID-19. A multivariable regression model was used to examine the effect of immunosuppressant drugs on the risk of infection by COVID-19 and the outcomes. Results: Of 144 IBD patients, 104 (72%) were CD and 40 (28%) were UC. Mean age was 32.2 ± 12.6 years. No mortalities were reported. In total, 94 patients (65.3%) received biologic therapy. Of them, 51 (54%) at escalated doses, 10 (11%) in combination with immunomodulators and 9 (10%) with concomitant corticosteroids. Disease location, behavior and activity did not correlate with the severity of COVID-19. Biologics as monotherapy or with immunomodulators or corticosteroids were not associated with more severe infection. On the contrary, patients receiving biologics had significantly milder infection course (p = 0.001) and were less likely to be hospitalized (p = 0.001). Treatment was postponed in 34.7% of patients until recovery from COVID-19, without consequent exacerbation. Conclusion: We did not witness aggravated COVID-19 outcomes in patients with IBD. Patients treated with biologics had a favorable outcome. Full article
