ABSTRACT
Background: Several SARS-CoV-2 vaccines are highly effective in preventing most infections, serious disease, hospitalization, and death from COVID-19 in the general population, but data regarding their use and efficacy in patients with inflammatory bowel disease (IBD) are limited. In this study we assessed the use patterns and efficacy of SARS-CoV-2 vaccines in patients with IBD. Methods: We established a multicenter matched case-control cohort of patients with IBD [Crohn's disease (CD), ulcerative colitis (UC)] and COVID-19 between February 2020 and December 2020 for the Surveillance of COVID-19 Impact on Long- Term Outcomes in IBD (SCOUT IBD) study. Cases were defined by the presence of COVID- 19-related symptoms and confirmatory SARS-CoV-2 PCR or IgG testing and non-COVID controls were defined as absence of symptoms and both a negative PCR and IgG in 2020. Cases were matched 1:1 to controls based on age, sex and IBD type. Data were collected on vaccine administration in 2021 and incidence of interval COVID-19 (defined as above) between January and September 2021. Results: The total cohort included 502 patients with IBD [UC (n=222, 44%), CD (n=278, 55%), IBD-undefined (n=2, 1%)] of whom 251 had a history of COVID-19 in 2020. The overall vaccination rate was 61% (n=306) with 189 (62%) patients receiving Pfizer-BioNTech, 101 (33%) Moderna, and 12 (4%) Johnson & Johnson. Vaccinated patients were more likely to be older (P=0.02), female (P=0.07), have a co-morbidity (cardiovascular, respiratory, renal) (P=0.04), or currently be on a biologic (P=0.01), and less likely to have had prior COVID-19 (P<0.001) than patients who did not get vaccinated (Table 1). The overall incidence of interval COVID-19 was 1.6% (N=8), with an infection rate of 0.3% (1/311) in vaccinated patients vs. 3.7% (7/184) in unvaccinated patients (P<0.01). Of infections occurring in unvaccinated patients, 1/7 (14.2%) was severe and required hospitalization requiring ICU admission, and the breakthrough infection in the vaccinated patient was mild and self-limited. COVID-19 reinfection occurred in one patient (0.4%) with prior COVID-19 who was unvaccinated. Under multivariable logistic regression, COVID-19 vaccination (aOR 0.05, 95% CI 0.01-0.41) and prior COVID-19 infection (OR 0.07, 95% CI 0.01-0.63) were highly protective against interval COVID-19. Conclusion: COVID-19 vaccines are effective in patients with IBD and markedly reduce the incidence of COVID-19. Prior COVID-19 is also protective against subsequent infection, although re-infections may occur at a very low rate. These results reaffirm the importance of COVID-19 vaccination in patients with IBD.(Table Presented)(Table Presented)
ABSTRACT
Background: Inflammatory bowel disease (IBD) and IBD-related biologic therapies are not associated with worse outcomes of Coronavirus Disease 2019 (COVID-19), however, data are lacking regarding the long-term impact of COVID-19 and its inflammatory sequelae on the disease course of IBD. We aimed to investigate the long-term outcomes of patients with IBD and COVID-19. Methods: We performed a multicenter matched case-control study of patients with IBD [Crohn's disease (CD), ulcerative colitis (UC)] and COVID-19 between February 2020 and December 2020 at 5 large health systems. Cases were defined by the presence of COVID-19-related symptoms and confirmatory SARS-CoV-2 PCR or IgG testing. Non-COVID controls were defined as absence of symptoms and both a negative PCR and IgG during the study entry period. Cases were matched 1:1 to controls based on age, sex and IBD type. The primary composite outcome was IBD-related hospitalization or surgery, and outcomes were sub-stratified by COVID-19 severity. Results: We identified 251 cases with IBD [UC (n=111, 44%), CD (n=139, 55%)] and confirmed COVID-19, matched with 251 non-COVID-19 IBD controls, with a median follow-up of 394 days. COVID-19 patients had higher rates of prior IBD-related hospitalizations (36% vs. 27%;P=0.03), corticosteroid use (75% vs. 65%;P=0.06), and biologic exposure (73% vs. 64%;P=0.04) than controls. There were no differences in UC extent or CD phenotype between groups. In COVID-19 positive patients, the most common symptoms were fever (61%), cough (48%), fatigue (30%) and diarrhea (28%). Severe COVID-19 (defined as hospitalization, ICU requirement or mechanical ventilation) occurred in 16% (n=39) of cases. The primary composite outcome of IBD-related hospitalization or surgery occurred in 12% (n=38) of cases vs. 15% (n=29) of controls (P=0.24;Table 1). When further stratified by COVID-19 severity, the incidence of the primary composite outcome was highest in patients with severe COVID-19, followed by controls and non-severe COVID-19 (Figure 1). Under multivariate Cox regression, severe COVID-19 remained a predictor of worse IBD outcomes (aHR 2.09, 95% CI 0.91-4.86) whereas non-severe COVID-19 was associated with decreased risk (aHR 0.52, 95% CI 0.28- 0.99). Prior IBD-related hospitalization or surgery (aHR 3.10, 95% CI 1.70-6.57) and current steroid use (aHR 2.17, 95% CI 0.95-4.94) were also predictive of worse IBD outcomes. Conclusion: In this matched case-control study, a history of any COVID-19 infection did not appear to exacerbate the course of IBD, however, severe COVID-19 was associated with worse IBD outcomes. These data suggest that the inflammatory sequelae of COVID-19 may adversely impact the subsequent disease course of IBD. Further studies are required to confirm these associations, which underscore the importance of COVID-19 mitigation measures.(Table Presented) (Figure Presented)
ABSTRACT
Introduction: The start of the COVID-19 pandemic in March 2020 led to an increased rate of telehealth visits. Older adults, however, may be more vulnerable to missing appointments given cognitive, physical, and technological gaps. We looked to determine the completion rate of telehealth appointments for older adults with inflammatory bowel disease (IBD), as well as predictors of incomplete appointments. Methods: We conducted a retrospective analysis of all patients with IBD who had at least one telehealth visit at the NYU IBD Center between 3/1/2020-8/31/2021. Only the status of the first telehealth appointment was considered, with an incomplete visit defined as left before being seen, a cancellation or noshow. Medical records were parsed for relevant co-variables, and logistic regression was used to estimate the adjusted association between demographic factors and telehealth appointment completion rates. Results: From 3/1/2020 to 8/31/2021 there were 2,508 patients with inflammatory bowel disease (IBD) who had at least one telehealth appointment, with 1088 (43%) having Crohn's disease (CD), 1037 (41%) having ulcerative colitis (UC), and 383 (15%) with indeterminate colitis (Table 1). Of the 2,508 initial telehealth visits, 519 (21%) were not completed, including 435 (20%) among patients under the age of 60-years as compared to 84 (23%) among patients over the age of 60-years. On multivariable analysis, patients with CD had higher odds of an incomplete appointment as compared to patients with UC (adjOR 1.37, 95%CI 1.10-1.69). Additionally, females had significantly higher odds of an incomplete appointment vs. males (adjOR 1.26, 95%CI 1.04-1.54), and patients who had a non-1st degree relative listed as an emergency contact also had significantly higher odds of an incomplete appointment vs. those with a spouse listed (adjOR 1.69, 95%CI 1.16-2.44;Table 2). Age over 60-years, partnership status, and comorbidities were not associated with appointment completion rates. Among the 361 patients over the age of 60-years who had a telehealth appointment, sex, emergency contact information, IBD subtype, and partnership status were not found to be associated with odds of completing a telehealth appointment. Conclusions: In our study, older patients with IBD were not at higher risk for missed telehealth appointments as compared to younger patients. On multivariable analysis, patients with CD as compared to patients with UC, females as compared to males, and patients who had a non-1st degree relative listed as an emergency contact as compared to those who had a spouse listed were more likely to miss telehealth appointments. Future studies should explore the role of these factors, including the role of social support, in order to design interventions aimed at limiting missed telehealth appointments.
