Transfusion of PCs in PAS-2 significantly reduces the incidence of reactions. The 1-hour and 20-hour CCIs after transfusion of PCs in PAS-2 were significantly lower than the CCIs after transfusion of PCs in plasma. Because storage conditions of both PCs were found to be optimal, the decrease in CCIs after transfusion of PCs prepared in PAS-2 may be caused by rapid elimination of a subpopulation of P-selectin-positive platelets from the circulation.
Background and aims
The COVID-19 risk and disease course in inflammatory bowel disease (IBD) patients remains uncertain. Therefore, we aimed to assess the clinical presentation, disease course and outcomes of COVID-19 in IBD patients. Second, we determined COVID-19 incidences in IBD patients and compared this with the general population.
Methods
We conducted a multicenter, nationwide IBD cohort study in the Netherlands and identified patients with COVID-19. First, we assessed the COVID-19 disease course and outcomes. Second, we compared COVID-19 incidences between our IBD study cohort and the general Dutch population.
Results
We established an IBD cohort of 34,763 patients. COVID-19 was diagnosed in 100/34,763 patients (0.29%). 20/100 patients (20%) had severe COVID-19 defined as admission to the intensive care unit, mechanical ventilation, and/or death. Hospitalization occurred in 59/100 (59.0%) patients and 13/100 (13.0%) died. All patients who deceased had comorbidities and all but one were > 65 years. In line, we identified > 1 comorbidity as an independent risk factor for hospitalization (OR 4.20, 95% CI 1.58-11.17, p = 0.004). Incidences of COVID-19 between the IBD study cohort and the general population were comparable (287.6 (95% CI 236.6-349.7) versus 333.0 (95% CI 329.3-336.7) per 100,000 patients, respectively; p = 0.15).
Conclusions
Of 100 cases with IBD and COVID-19, 20% developed severe COVID-19, 59% was hospitalized and 13% died. A comparable COVID-19 risk was found between the IBD cohort (100/34,763 = 0.29%) and the general Dutch population. The presence of > 1 comorbidities was an independent risk factor for hospitalization due to COVID-19.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
