Low Adherence is Associated with Chronic Active Disease in Ulcerative Colitis: A Retrospective Study from a Single Referral Center.

Purpose: New therapeutic approaches for ulcerative colitis (UC) are now available, but there is still no robust evidence for predictors of poor outcomes. We aimed to evaluate the factors associated with a chronic active UC disease course. Patients and Methods: Data of all UC outpatients followed for at least 3 years after diagnosis between 2005 and 2018 were retrospectively collected. The primary aim was to identify risk factors for chronic active disease 3 years after diagnosis. Moreover, the following variables were investigated: proximal disease extension or disease regression, proctocolectomy, early use of biologics (BIO) or immunomodulators (IMM), hospitalization, colorectal cancer, and adherence. We defined adherence as both, taking the prescribed therapy and constancy in scheduled follow-up visits. Results: A total of 345 UC patients followed for a median period of 82 months were included. Patients with extensive colitis at diagnosis had a higher rate of chronic active disease 3 years after diagnosis (p<0.012) together with a higher rate of surgery (p<0.001) at maximum follow-up. Patients with pancolitis showed significant disease regression over time (51%) without differences in treatment. The only factor associated with chronic active disease was non-adherence (p < 0.03; OR 0.49, 95% CI: 0.26-0.95). Adherent patients developed chronic active disease (p<0.025) less frequently but did receive more frequent IMM (p<0.045) or BIO (p<0.009) therapy. Conclusion: Patients diagnosed with pancolitis were more likely to have chronic active disease and to undergo colectomy. The only predictor for developing chronically active UC regardless of disease extension was the lack of adherence to therapy within the first 3 years after diagnosis, underlining the importance of tight control of UC patients and the need to timely identify potential risk factors for non-adherence.

Severe Activity of Inflammatory Bowel Disease is a Risk Factor for Severe COVID-19.

BACKGROUND: Data from the first wave of the coronavirus disease 2019 (COVID-19) pandemic suggested that patients with inflammatory bowel disease (IBD) are not at higher risk of being infected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) than the general population and that a worse prognosis is not associated with immunomodulatory drugs, with the possible exception of systemic steroids. METHODS: This retrospective, observational study included consecutive IBD patients from the Sicilian Network for Inflammatory Bowel Disease (SN-IBD) cohort who had a SARS-CoV-2 infection diagnosis (polymerase chain reaction-confirmed presence of the viral genome in a nasopharyngeal swab) during the second COVID-19 pandemic wave (September 2020 to December 2020). Data regarding demographics, IBD features and treatments, and comorbidities were analyzed in correlation with COVID-19 clinical outcomes. RESULTS: Data on 122 patients (mean age, 43.9 ±â€…16.7 years; males, 50.0%; Crohn's disease, 62.3%; ulcerative colitis, 37.7%) were reported. Twelve patients developed COVID-19-related pneumonia (9.8%), 4 (3.3%) required respiratory assistance (nonmechanical ventilation or orotracheal intubation), and 4 died (case fatality rate, 3.3%). In a multivariable analysis, age (odds ratio [OR], 1.034; 95% CI, 1.006-1.147; P = .032) and severe IBD activity (OR, 13.465; 95% CI, 1.104-164.182; P = .042) were independent predictors of COVID-19-related pneumonia, while severe IBD activity (OR, 15.359; 95% CI, 1.320-178.677; P = .030) was the only independent predictor of severe COVID-19, a composite endpoint defined as the need for respiratory assistance or death. A trend towards a protective role of tumor necrosis factor α inhibitors on pneumonia development was reported (P = .076). CONCLUSIONS: In this cohort of patients with IBD and SARS-CoV-2 infection, severe IBD activity was the only independent risk factor for severe COVID-19.

This retrospective, observational study on patients with inflammatory bowel disease and severe acute respiratory syndrome coronavirus 2 infection showed that severe inflammatory bowel disease activity was the only independent risk factor for severe coronavirus disease 2019.
