COVID-19 vaccination rate and willingness of an additional dose among inflammatory bowel disease patients receiving biologic therapy: Fearless and with desire

Role of gastroenterologists and healthcare providers in promoting COVID-19 immunization among individuals with inflammatory bowel disease: A systematic review and meta-analysis on a global scale

Individuals with Inflammatory Bowel Disease (IBD) are more susceptible to experiencing severe complications of COVID-19 if infected. Nevertheless, sub-optimal immunization rates have been reported among these patients. Our study aims to assess COVID-19 VH among a global population of patients with IBD and to investigate the role of healthcare professionals, particularly gastroenterologists, in promoting immunization. Twenty-six studies were systematically selected from scientific articles in the MEDLINE/PubMed, WoK, and Scopus databases from January 1, 2020, to September 15, 2023. The pooled prevalence of COVID-19 VH was 27.2% (95%CI = 20.6-34.2%). A significant relationship was evidenced between COVID-19 vaccine compliance and receiving advice from gastroenterologists or healthcare providers (OR = 2.77; 95%CI = 1.79-4.30). By leveraging their knowledge of IBD, familiarity with patient histories, and trusted patient-doctor relationships, gastroenterologists are pivotal in promoting vaccination. This patient-centered care is crucial in increasing vaccine acceptance among individuals with IBD, contributing to better public health outcomes.

Vaccine adherence and adverse events of the SARS-COV vaccine in patients with inflammatory bowel disease

OBJECTIVE

To assess adherence to and the adverse effects of the SARS-COV vaccine in patients with inflammatory bowel disease (IBD).

PATIENTS AND METHODS

This is an observational, analytical, cross-sectional study. Sociodemographic and clinical data, SARS-COV vaccine data, medications for IBD with use during the vaccination period, and adverse events during the vaccination period were collected. Carried out logistic regressions with robust variance estimation to estimate the odds ratio with the respective 95% confidence intervals (95%CI) to assess the factors associated with non-serious adverse effects following vaccine doses as outcome variables.

RESULTS

194 patients participated, with vaccine compliance of 78.3% for three doses of any vaccine (n=152). Local symptoms and mild systemic symptoms predominated, regardless of the type of vaccine. The first dose of the SARS-COV vaccine with AstraZeneca had a higher percentage of patients with vaccine symptoms. AstraZeneca vaccine increased the chance of non-serious adverse effects in IBD patients by 2.65 times (95% CI: 1.38-5.08; p=0.003), regardless of age, gender, physical activity, excess weight, use of disease-modifying drugs, immunobiological and corticosteroids. CoronaVac vaccine was associated with asymptomatic patients at the first dose and reduced the chance of adverse effects by 0.28 times (OR: 0.284; 95%CI: 0.13-0.62; p=0.002).

CONCLUSION

Local symptoms and mild systemic symptoms predominated, regardless of the type of vaccine. Using CoronaVac in the first dose reduced the chances of adverse effects, while AstraZeneca increased the risk of adverse effects.

COVID-19 Vaccination Coverage and Associated Factors in Patients with Multiple Sclerosis

Our objective was to know the COVID-19 vaccination coverage in multiple sclerosis (MS) patients and its factors associated. A retrospective cohort study was carried out. Patients seen at the MS unit of the University Clinical Hospital of Zaragoza between 2017 and 2021 were included. Variables were obtained by reviewing the specialized and primary care records. Associations between receiving COVID-19 full primo-vaccination, as well as one booster dose since autumn 2022, and the other variables were analyzed using bivariate analysis and multiple logistic regression models. Of the 359 included patients, 90.3% received the COVID-19 full primo-vaccination. Having been born in Spain (aOR = 3.40) and having received the 2020-2021 influenza vaccine (aOR = 6.77) were associated with receiving the COVID-19 full primo-vaccination. Vaccination with a COVID-19 booster dose was detected in 141 patients (39.3%). Sex (man) (aOR = 2.36), age (60 years or over) (aOR = 6.82), type of MS (Primary Progressive/Secondary Progressive) (aOR = 3.94), and having received the 2022-2023 influenza vaccine (aOR = 27.54) were associated with receiving such a booster dose. The COVID-19 booster dose was administered at the same time as the 2022-2023 influenza vaccine in 57.8% (67/116) of the patients vaccinated with both vaccines. The COVID-19 full primo-vaccination coverage is higher than in other countries. However, the decrease in vaccination coverage with the booster dose makes it necessary to develop strategies to improve it that are not limited to administering the flu vaccine together with the COVID-19 booster dose. Such strategies should be in focus, especially for women under 60 years of age.

Low vaccination and infection rate of Omicron in patients with inflammatory bowel disease: a comparative study of three unique cohorts

Background

The SARS-CoV-2 Omicron variant caused a large-scale outbreak of COVID-19 in Shanghai, China. Patients with inflammatory bowel disease (IBD) are at high risk of infection due to immunosuppressive interventions. We aimed to investigate the vaccination information of patients with IBD and update a vaccination guide based on a comparison of vaccination in asymptomatic carriers and healthy individuals.

Methods

This retrospective study was conducted during an Omicron variant wave. We assessed the vaccination status in patients with IBD, asymptomatic carriers and healthy individuals. Factors with unvaccinated status and adverse events following vaccination were also determined in patients with IBD.

Results

The vaccination rate was 51.2% in patients with IBD, 73.2% in asymptomatic carriers, and 96.1% in healthy individuals. Female sex (p = 0.012), Crohn's disease (p = 0.026), and disease behavior of B3 (p = 0.029) were factors that indicated a lower vaccination rate. A significantly higher proportion of healthy individuals had received one booster dose (76.8%) than asymptomatic carriers (43.4%) and patients with IBD (26.2%). Patients with IBD received vaccination without an increased risk of adverse events (p = 0.768).

Conclusion

The vaccination rate of patients with IBD remains much lower than that of asymptomatic carriers and healthy individuals. The COVID-19 vaccine has been found to be safe among all three groups and patients with IBD are not more susceptible to adverse events.
