Impact of Holding Immunosuppressive Therapy in Patients with Inflammatory Bowel Disease Around mRNA COVID-19 Vaccine Administration on Humoral Immune Response and Development of COVID-19 Infection.

BACKGROUND AND AIMS: The BNT162b2 and mRNA-1273 COVID-19 vaccines are efficacious in patients with inflammatory bowel disease; but there are a lack of data examining if holding immunosuppressive therapy around vaccination improves immune response. We studied the effect of holding IBD medications around the time of vaccination on antibody response and breakthrough COVID-19 infection. METHODS: Partnership to Report Effectiveness of Vaccination in populations Excluded from iNitial Trials of COVID is a prospective cohort of individuals with IBD receiving COVID-19 vaccination. Quantitative measurement of anti-receptor binding domain IgG antibodies to SARS-CoV-2 was performed 8 weeks after completing a vaccination series. RESULTS: 1,854 patients were included; 59% were on anti-TNF (10% of these on combination therapy), 11% on vedolizumab, and 14% on ustekinumab. 11% of participants held therapy before or after vaccine administration for at least 2 weeks. Antibody levels were similar in participants continuing versus holding anti-TNF monotherapy before or after the second vaccine (BNT162b2: 10 µg/mL vs 8.9 µg/mL, mRNA-1273: 17.5 µg/mL vs 14.5 µg/mL). Comparable results were seen in those on combination therapy. Antibody titers in those on ustekinumab or vedolizumab were higher compared to anti-TNF users, but there was no significant difference if drug was held or continued (BNT162b2: 22.5 µg/mL vs 23 µg/mL, mRNA-1273: 88 µg/mL vs 51 µg/mL). Holding therapy was not associated with decreased rate of COVID-19 infection compared to those not holding therapy (BNT162b2: 28% vs 29%; mRNA-1273 19% vs 31%). CONCLUSION: We recommend continuing IBD medications while receiving mRNA COVID-19 vaccination without interruption.

Low Rates of Breakthrough COVID-19 Infection After SARS-CoV-2 Vaccination in Patients With Inflammatory Bowel Disease.

We demonstrate low rates of breakthrough coronavirus disease 2019 (COVID-19) infection and mild course of illness following severe acute respiratory syndrome coronavirus 2 vaccination in a large cohort of inflammatory bowel disease patients. Residence in southern United States and lower median anti-receptor binding antibody level were associated with development of COVID-19.

Humoral Immune Response and Safety of SARS-CoV-2 Vaccination in Pediatric Inflammatory Bowel Disease.

INTRODUCTION: Children with inflammatory bowel disease (IBD) may respond differently to COVID-19 immunization as compared with healthy children or adults with IBD. Those younger than 12 years receive a lower vaccine dose than adults. We sought to describe the safety and humoral immune response to COVID-19 vaccine in children with IBD. METHODS: We recruited children with IBD, ages 5-17 years, who received ≥ 2 doses of the BNT162b2 vaccine by a direct-to-patient outreach and at select sites. Patient demographics, IBD characteristics, medication use, and vaccine adverse events were collected. A subset of participants had quantitative measurement of anti-receptor binding domain IgG antibodies after 2-part immunization. RESULTS: Our study population included 280 participants. Only 1 participant required an ED visit or hospitalization because of an adverse event. Of 99 participants who underwent anti-receptor binding domain IgG antibody measurement, 98 had a detectable antibody, with a mean antibody level of 43.0 µg/mL (SD 67) and a median of 22 µg/mL (interquartile range 12-38). In adjusted analyses, older age ( P = 0.028) and antitumor necrosis factor monotherapy compared with immunomodulators alone ( P = 0.005) were associated with a decreased antibody level. Antibody response in patients treated with antitumor necrosis factor combination vs monotherapy was numerically lower but not significant. DISCUSSION: Humoral immune response to COVID-19 immunization in children with IBD was robust, despite a high proportion of this pediatric cohort being treated with immunosuppressive agents. Severe vaccine-related AEs were rare. Overall, these findings provide a high level of reassurance that pediatric patients with IBD respond well and safely to SARS-CoV-2 vaccination.

Risks of Development of COVID-19 Among Patients With Inflammatory Bowel Disease: A Comparative Assessment of Risk Factors for Incident Infection.

Background: Patients with inflammatory bowel disease (IBD) may be at risk for development of COVID-19 infection due to innate immune dysfunction and/or immunosuppressive medication use. Methods: In a prospective cohort of adult IBD patients, we captured data on clinical risk factors and IBD medication utilization. The outcome of interest was development of patient-reported laboratory confirmed COVID-19. We calculated incidence rate and performed bivariate analyses to describe the effects of risk factors (age, immunosuppression use, obesity, and race) on development of COVID-19. We utilized logistic regression models to determine the independent risks associated with each factor. Results: A total of 3953 patients with IBD were followed for a mean duration of 212 days (SD 157). A total of 103 individuals developed COVID-19 during follow-up (2.6%, rate of 45 per 1000 person-years). Severity of infection was generally mild. Clinical characteristics were similar among those who developed COVID-19 as compared to not. African American race was associated with incident COVID-19 infection (OR 3.37, 95% CI 1.18-9.59). Immunosuppression use was not associated with development of COVID-19 (OR 1.19, 95% CI 0.72-1.75), nor was age (OR 1.00, 95% CI 0.99-1.02), nor obesity (OR 1.01, 95% CI 0.61-1.66). Conclusions: Immunosuppression use did not increase the risk of development of COVID-19. Therapeutic management of IBD should not be altered to prevent a risk of developing COVID-19.

Strong Response to SARS-CoV-2 Vaccine Additional Doses Among Patients With Inflammatory Bowel Diseases.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has disrupted health care and has resulted in high mortality rates.1 Vaccination is an international priority to mitigate the risks of SARS-CoV-2. The initial trials for development of SARS-CoV-2 vaccines excluded individuals with immunocompromising conditions.2.

Implementing Collaborative Care Management of Behavioral Health for Patients with Inflammatory Bowel Disease.

Background: Individuals with inflammatory bowel disease (IBD) are up to twice as likely to suffer from anxiety and/or depression. Collaborative care management (CoCM) is an evidence-based approach to treating behavioral health disorders that have proven effective for a range of conditions in primary care and some specialty settings. This model involves a team-based approach, with care delivered by a care manager (case reviews and behavioral therapy), psychiatrist (case reviews and psychopharmacological recommendations), and medical provider (ongoing care including psychopharmacological prescriptions). We assessed the feasibility and effectiveness of CoCM in reducing anxiety and depressive symptoms in patients with IBD. Methods: Patients with psychological distress identified by clinical impression and/or the results of the Patient Health Questionaire-9 (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7) were referred to the CoCM program. Data from our 9-month CoCM pilot were collected to assess depression and anxiety response and remission rates. We obtained provider surveys to assess provider acceptability with delivering care in this model. Results: Though the SARS-CoV2 COVID-19 pandemic interrupted screening, 39 patients enrolled and 19 active participants completed the program. Overall, 47.4% had either a response or remission in depression, while 36.8% had response or remission in anxiety. The gastroenterologists highly agreed that the program was a beneficial resource for their patients and felt comfortable implementing the recommendations. Discussion: CoCM is a potentially feasible and well accepted care delivery model for treatment of depression and anxiety in patients with IBD in a specialty gastroenterology clinic setting.

Factors Affecting Initial Humoral Immune Response to SARS-CoV-2 Vaccines Among Patients With Inflammatory Bowel Diseases.

INTRODUCTION: Although an additional coronavirus disease 2019 vaccine dose for immunocompromised persons has been recommended in some countries, further data to guide vaccination strategies for patients with inflammatory bowel disease (IBD) are urgently needed. We sought to identify factors affecting initial humoral immune response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines among patients with IBD. METHODS: In this prospective cohort of SARS-CoV-2 immunized patients with IBD, we evaluated associations between participant age, sex, vaccine type, medication use, and the presence of a detectable antireceptor binding domain antibody and quantitative antibody level. RESULTS: In total, 1,909 participants were included (1,123, 692, and 94 received BNT162b2, mRNA-1273, and Ad26.COV2.S, respectively) of whom 96% achieved a positive antibody response. On multivariable analysis, factors associated with lack of antibody response were older age (P = 0.043), BNT162b2 vs mRNA-1273 (odds ratio [OR] 2.1, 95% confidence interval [CI] 1.0-3.9), and combination therapy with anti-TNF and 6MP, azathioprine, or methotrexate (OR 4.2, 95% CI 2.4-7.3). The use of 5-aminosalicylate or sulfasalazine (OR 0.3, 95% CI 0.1-0.8) and ustekinumab (OR 0.2, 95% CI 0.05-0.8) was associated with decreased odds of lacking antibody response. DISCUSSION: Most patients with IBD mount an initial response to SARS-CoV-2 vaccination; however, older patients and those treated with anti-TNF and immunomodulator have blunted responses and may benefit the most from an additional vaccine dose. Patients treated with other classes of immunosuppressive medications have more robust initial immune responses to vaccination. These data should inform key decisions about patient selection for additional coronavirus disease 2019 vaccine doses in patients with IBD.

Impact of SARS-CoV-2 Vaccination on Inflammatory Bowel Disease Activity and Development of Vaccine-Related Adverse Events: Results From PREVENT-COVID.

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 vaccination is recommended for all individuals with inflammatory bowel disease (IBD), including those on immunosuppressive therapies; however, little is known about vaccine safety and efficacy in these patients or the impact of vaccination on IBD disease course. METHODS: We evaluated coronavirus disease 2019 (COVID-19) vaccine-related adverse events (AEs) and the effect of vaccination on IBD disease course among participants in the PREVENT-COVID (Partnership to Report Effectiveness of Vaccination in populations Excluded from iNitial Trials of COVID) study, a prospective, observational cohort study. Localized and systemic reactions were assessed via questionnaire. Disease flare was defined by worsening IBD symptoms and change in IBD medications. Outcomes were stratified by vaccine type and IBD medication classes. RESULTS: A total of 3316 individuals with IBD received at least 1 COVID-19 vaccine. Injection site tenderness (68%) and fatigue (46% dose 1, 68% dose 2) were the most commonly reported localized and systemic AEs after vaccination. Severe localized and systemic vaccine-related AEs were rare. The mRNA-1273 vaccine was associated with significantly greater severe AEs at dose 2 (localized 4% vs 2%, systemic 15% vs 10%; P < .001 for both). Prior COVID-19 infection, female sex, and vaccine type were associated with severe systemic reactions to dose 1, while age <50 years, female sex, vaccine type, and antitumor necrosis factor and vedolizumab use were associated with severe systemic reactions to dose 2. Overall rates (2%) of IBD flare were low following vaccination. CONCLUSIONS: Our findings provide reassurance that the severe acute respiratory syndrome coronavirus 2 vaccine is safe and well tolerated among individuals with IBD, which may help to combat vaccine hesitancy and increase vaccine confidence.

The severe acute respiratory syndrome coronavirus 2 vaccine is safe and well tolerated among individuals with inflammatory bowel disease (IBD). Severe localized and systemic vaccine-related adverse events were rare, and rates of IBD flare were low (2%) following severe acute respiratory syndrome coronavirus 2 vaccination in a cohort of 3316 participants with IBD.

A Patient-Prioritized Agenda for Information Needs During the COVID-19 Pandemic: A Qualitative Study of Patients With Inflammatory Bowel Disease.

BACKGROUND: Patients with inflammatory bowel disease (IBD) may be at risk for complications due to the COVID-19 pandemic. We performed a qualitative study to better understand IBD patient experiences and concerns when navigating the COVID-19 pandemic, with the goal of prioritizing patients' information needs. METHODS: We conducted a series of semistructured virtual focus groups at 6 months, then member checking focus groups 1 year into the COVID-19 pandemic. We included questions on patients' experiences navigating the pandemic with IBD, differences in their experience as compared to peers, their concerns and fears, as well as preferred information sources. Transcribed focus groups were coded and content analyzed to summarize key areas of interest and identify themes. We focused on 4 areas in our content analysis process: fears, challenges, information preferences, and research questions. RESULTS: A total of 26 IBD patient participants were included in the initial focus groups. Findings highlighted the many challenges faced by patients during the COVID-19 pandemic, ranging from access (bathrooms, medications, healthcare) to significant fears and concerns surrounding medications used for IBD worsening risks of COVID-19. Research questions of importance to patients centered on understanding risks for COVID-19 complications, particularly pertaining to medication utilization, with a shift over time toward understanding COVID-19 vaccination. In our member checking focus groups (n = 8 participants), themes were reiterated, with a central focus of research questions pertaining to COVID-19 vaccination. CONCLUSIONS: Information needs for patients during the COVID-19 pandemic centered upon understanding disease-specific risks. Identified challenges and fears will inform future research agendas and communication with patients.

Increased colonic expression of ACE2 associates with poor prognosis in Crohn's disease.

The host receptor for SARS-CoV-2, angiotensin-converting enzyme 2 (ACE2), is highly expressed in small intestine. Our aim was to study colonic ACE2 expression in Crohn's disease (CD) and non-inflammatory bowel disease (non-IBD) controls. We hypothesized that the colonic expression levels of ACE2 impacts CD course. We examined the expression of colonic ACE2 in 67 adult CD and 14 NIBD control patients using RNA-seq and quantitative (q) RT-PCR. We validated ACE2 protein expression and localization in formalin-fixed, paraffin-embedded matched colon and ileal tissues using immunohistochemistry. The impact of increased ACE2 expression in CD for the risk of surgery was evaluated by a multivariate regression analysis and a Kaplan-Meier estimator. To provide critical support for the generality of our findings, we analyzed previously published RNA-seq data from two large independent cohorts of CD patients. Colonic ACE2 expression was significantly higher in a subset of adult CD patients which was defined as the ACE2-high CD subset. IHC in a sampling of ACE2-high CD patients confirmed high ACE2 protein expression in the colon and ileum compared to ACE2-low CD and NIBD patients. Notably, we found that ACE2-high CD patients are significantly more likely to undergo surgery within 5 years of CD diagnosis, and a Cox regression analysis found that high ACE2 levels is an independent risk factor for surgery (OR 2.17; 95% CI, 1.10-4.26; p = 0.025). Increased intestinal expression of ACE2 is associated with deteriorated clinical outcomes in CD patients. These data point to the need for molecular stratification that can impact CD disease-related outcomes.
