Safety of Immunizations for the Adult Patient With Inflammatory Bowel Disease-A Systematic Review and Meta-analysis

AGA Clinical Practice Update on Noncolorectal Cancer Screening and Vaccinations in Patients With Inflammatory Bowel Disease: Expert Review

DESCRIPTION

The aim of this American Gastroenterological Association (AGA) Clinical Practice Update (CPU) is to provide Best Practice Advice statements for gastroenterologists and other healthcare providers who provide care to patients with inflammatory bowel disease (IBD). The focus is on IBD-specific screenings (excluding colorectal cancer screening, which is discussed separately) and vaccinations. We provide guidance to ensure that patients are up to date with the disease-specific cancer screenings and vaccinations, as well as advice for mental health and general well-being.

METHODS

This expert review was commissioned and approved by the AGA CPU Committee and the AGA Governing Board to provide timely guidance on a topic of high clinical importance to the AGA membership and underwent internal peer review by the CPU Committee and external peer review through standard procedures of Clinical Gastroenterology and Hepatology. The Best Practice Advice statements were drawn from reviewing existing literature combined with expert opinion to provide practical advice on the screening for noncolorectal cancers and vaccinations in patients with IBD. Because this was not a systematic review, formal rating of the quality of evidence or strength of the presented considerations was not performed. Best Practice Advice Statements BEST PRACTICE ADVICE 1: All adult patients with IBD should receive age-appropriate cancer screening. BEST PRACTICE ADVICE 2: Adult women with IBD should follow age-appropriate screening for cervical dysplasia. Data are insufficient to determine whether patients receiving combined immunosuppression or thiopurines require more frequent screening. Shared decision making and individual risk stratification are encouraged. BEST PRACTICE ADVICE 3: All adult patients with IBD should follow skin cancer primary prevention practices by avoiding excessive exposure to the sun's ultraviolet radiation. Patients on immunomodulators, anti-tumor necrosis factor biologic agents, or small molecules should undergo yearly total body skin exam. Patients with any history of thiopurine use should continue with yearly total body skin exam even after thiopurine cessation. BEST PRACTICE ADVICE 4: At every colonoscopy, a thorough perianal and anal examination should be performed. Special attention should be made to inspection of the anal canal of patients with perianal Crohn's disease, with anal stricture, with human papillomavirus, with human immunodeficiency virus, and who engage in anoreceptive intercourse. BEST PRACTICE ADVICE 5: Gastroenterology clinicians should discuss age-appropriate vaccines with adult patients who have IBD and share responsibility with primary care providers for administering these vaccines. Patients with IBD should follow the adult immunization schedule advised by the Centers for Disease Control and Prevention (CDC) for all vaccines with the exception of live vaccines; Patients receiving immune-modifying agents should be counseled against receiving live vaccines; Immunization history to the 2 live pediatric vaccines, varicella and measles, mumps, and rubella vaccine series, is presumptive evidence of immunity. All adults 18 to 26 years of age should receive human papillomavirus vaccine series, and those between 27 and 45 of age years should be vaccinated if they are likely to have a new sexual partner. BEST PRACTICE ADVICE 6: Inactivated vaccines are safe in patients with IBD, and their administration is not associated with exacerbation of IBD activity. We suggest that patients receive vaccines at the earliest opportunity and preferably be off corticosteroids or at the lowest tolerable corticosteroid dose. BEST PRACTICE ADVICE 7: All adult patients with IBD should be evaluated for latent hepatitis B infection. Patients who have previously completed a full hepatitis B vaccine series but are not seroprotected (hepatitis B surface antibody [anti-HBs] <10 mIU/mL) should receive a single challenge dose of hepatitis B vaccine; Four to 8 weeks after this challenge dose, their anti-HBs levels should be measured to evaluate for an amnestic response. An amnestic response, indicated by an anti-HBs level ≥10 mIU/mL (seroprotection), suggests immunologic memory, and no further doses are needed. If no amnestic response is observed, the patient should complete a second full 2- or 3-dose series of hepatitis B vaccination. BEST PRACTICE ADVICE 8: All adult patients with IBD should receive an annual inactivated influenza vaccine. Patients receiving anti-tumor necrosis factor monotherapy or who have undergone a solid organ transplant recipients can benefit from a high-dose influenza vaccine. Adults 65 years of age and older should receive a high-dose, recombinant, or adjuvanted influenza vaccine. Live attenuated intranasal vaccines should be avoided. BEST PRACTICE ADVICE 9: All adult patients with IBD 19 to 64 years of age should receive an initial pneumococcal vaccine, with an subsequent second pneumococcal vaccine administered at 65 years of age and older. BEST PRACTICE ADVICE 10: All adult patients with IBD who are 60 years of age and older should receive a respiratory syncytial virus vaccine. There is no preference for any of the available respiratory syncytial virus vaccines. BEST PRACTICE ADVICE 11: All adult patients 19 years of age and older receiving immune-modifying therapies, or with plans to initiate immune-modifying therapies, should receive a recombinant herpes zoster vaccine series, regardless of their prior varicella vaccination status. BEST PRACTICE ADVICE 12: Bone densitometry should be considered in patients with IBD, regardless of age, when risk factors for osteopenia and osteoporosis are present. These risk factors include low body mass index (<20 kg/m2), >3 months of cumulative corticosteroid exposure, current smoking, postmenopausal status, or hypogonadism. In the absence of other factors, bone densitometry should be considered for postmenopausal women and men 65 years or older. BEST PRACTICE ADVICE 13: All adult patients with IBD should be screened for depression and anxiety annually. Patients who screen positive for depression or anxiety should be referred to the appropriate specialist, be it their primary care physician or a mental health specialist.

Uptake and safety of pneumococcal vaccination in adults with immune-mediated inflammatory diseases: a UK wide observational study

OBJECTIVE

The uptake and safety of pneumococcal vaccination in people with immune-mediated inflammatory diseases (IMIDs) is poorly understood. We investigated the UK-wide pneumococcal vaccine uptake in adults with IMIDs and explored the association between vaccination and IMID flare.

METHODS

Adults with IMIDs diagnosed on or before 1 September 2018, prescribed steroid-sparing drugs within the last 12 months and contributing data to the Clinical Practice Research Datalink Gold, were included. Vaccine uptake was assessed using a cross-sectional study design. Self-controlled case series analysis investigated the association between pneumococcal vaccination and IMID flare. The self-controlled case series observation period was up to 6 months before and after pneumococcal vaccination. This was partitioned into a 14-day pre-vaccination induction, 90 days post-vaccination exposed and the remaining unexposed periods.

RESULTS

We included 32 277 patients, 14 151 with RA, 13 631 with IBD, 3804 with axial SpA and 691 with SLE. Overall, 57% were vaccinated against pneumococcus. Vaccine uptake was lower in those younger than 45 years old (32%), with IBD (42%) and without additional indication(s) for vaccination (46%). In the vaccine safety study, data for 1067, 935 and 451 vaccinated patients with primary-care consultations for joint pain, autoimmune rheumatic disease flare and IBD flare, respectively, were included. Vaccination against pneumococcal pneumonia was not associated with primary-care consultations for joint pain, autoimmune rheumatic disease flare and IBD flare in the exposed period, with incidence rate ratios (95% CI) 0.95 (0.83-1.09), 1.05 (0.92-1.19) and 0.83 (0.65-1.06), respectively.

CONCLUSION

Uptake of pneumococcal vaccination in UK patients with IMIDs was suboptimal. Vaccination against pneumococcal disease was not associated with IMID flare.

SARS-CoV-2 vaccination in inflammatory bowel disease patients is not associated with flares: a retrospective single-centre Swiss study

INTRODUCTION

Vaccination hesitancy is an important barrier to vaccination among IBD patients. The development of adverse events is the main concern reported. The purpose of this monocentric study was to assess SARS-CoV-2 vaccination safety in IBD patients by evaluating the postvaccination flare risk and incidence of overall adverse events.

METHODS

Surveys were handed out on three consecutive months to each patient presenting at the Crohn-Colitis Centre, where they documented their vaccination status and any side effects experienced after vaccination.Dates of flares occurring in 2021 were recorded from their electronic medical records. Baseline and IBD characteristics and flare incidence were compared between the vaccinated and unvaccinated patients, and among the vaccinated population before and after their vaccination doses. The characteristics of patients who developed side effects and of those who did not were compared.

RESULTS

We enrolled 396 IBD patients, of whom 91% were vaccinated. The proportion of patients who experienced flares was statistically not different between the vaccinated and the unvaccinated population (1.8 vs 2.6 flares per 100 person-months (p = 0.28)). Among vaccinated patients, there was no difference across the prevaccination, 1 month post any vaccination, and more than 1 month after any vaccination periods, and between the Spikevax and Cominarty subgroups. Overall, 46% of patients reported vaccination side effects, mostly mild flu-like symptoms.

CONCLUSION

SARS-CoV-2 vaccination with mRNA vaccines seems safe, with mostly mild side effects. The IBD flare risk is not increased in the month following any vaccination.

Navigating Reproductive Care in Patients With Inflammatory Bowel Disease: A Comprehensive Review

Inflammatory bowel disease [IBD] is often diagnosed in patients during their reproductive years. It is crucial that both healthcare providers and patients are adequately informed to avoid misguided decisions regarding family planning. One of the most important aspects during conception and pregnancy is to maintain disease remission, as disease activity is associated with adverse pregnancy outcomes. Apart from methotrexate, most conventional drugs used in IBD are considered low risk during conception and pregnancy. For newer agents, evidence is still limited. If needed, surgery must not be postponed and should ideally be performed in specialized centres. In most patients, delivery should be vaginal except for patients with complex perianal disease, with an ileoanal pouch anastomosis, or if there is an obstetric contraindication. In children exposed to biological treatments during pregnancy, the risk of infections appears to be low, and psychomotor development is probably not affected. Regarding immunizations, the standard vaccination schedule for inactivated vaccines should be followed for children exposed to biologics in utero. In the case of live vaccines, such as rotavirus, decisions should be individualized and take into consideration the risk-benefit ratio, particularly in developing countries. In this review, we provide a comprehensive and updated overview of aspects related to fertility, pregnancy, breastfeeding, and the impact on the care of children born to mothers with IBD. Both the available evidence and areas of uncertainty are discussed, with the goal of assisting healthcare professionals caring for IBD patients during this important stage of their lives.

Common Mistakes in Managing Patients with Inflammatory Bowel Disease

Introduction: Errors are very common in medical practice and in particular, in the healthcare of patients with inflammatory bowel disease (IBD); however, most of these can be prevented. Aim: To address common errors in the management of IBD. Methods: Our approach to this problem consists in identifying mistakes frequently observed in clinical practice (according to our experience) in the management of patients with IBD, then reviewing the scientific evidence available on the subject, and finally proposing the most appropriate recommendation for each case. Results: The most common mistakes in the management of IBD include those related to diagnosis and differential diagnosis, prevention, nutrition and diet, treatment with different drugs (mainly 5-aminosalicylates, corticosteroids, thiopurines, and anti-TNF agents), extraintestinal manifestations, anemia, elderly patients, pregnancy, and surgery. Conclusions: Despite the availability of guidelines for both disease management and preventive aspects of IBD care, a considerable variation in clinical practice still remains. In this review, we have identified common mistakes in the management of patients with IBD in clinical practice. There is a clear need for a greater dissemination of clinical practice guidelines among gastroenterologists and for the implementation of ongoing training activities supported by scientific societies. Finally, it is desirable to follow IBD patients in specialized units, which would undoubtedly be associated with higher-quality healthcare and a lower likelihood of errors in managing these patients.

Effects of COVID-19 vaccines on patient-reported outcomes in patients with inflammatory bowel disease: a multicenter survey study in Korea

BACKGROUND/AIMS

The impact of vaccination on inflammatory bowel disease (IBD) patients is still unknown, and no studies have assessed the changes in patient-reported outcomes (PROs) after vaccination in patients with IBD. Therefore, in this study, we investigated the impact of vaccines on the PROs of patients with IBD.

METHODS

We conducted a questionnaire survey of patients with IBD who visited outpatient clinics at 4 specialized IBD clinics of referral university hospitals from April 2022 to June 2022. A total of 309 IBD patients were included in the study. Patient information was collected from a questionnaire and their medical records, including laboratory findings, were reviewed retrospectively. Risk factors associated with an increase in PROs after COVID-19 vaccination were analyzed using logistic regression analyses. In addition, we assessed whether there were differences in variables by vaccine order using the linear mixed model.

RESULTS

In multivariate analysis, young age ( < 40 years) and ulcerative colitis (UC) were found to be independent risk factors for aggravation of PROs in patients with IBD. In all patients, platelet count significantly increased with continued vaccination in multiple pairwise comparisons. In UC patients, PROs such as the short health scale, UC-abdominal signs and symptoms, and UC-bowel signs and symptoms were aggravated significantly with continued vaccination. There was no significant increase in the variables of patients with Crohn's disease.

CONCLUSIONS

Therefore, there may be a need to counsel patients with IBD younger than 40 years of age, and patients with UC before they receive COVID-19 vaccinations.

Uptake, safety and effectiveness of inactivated influenza vaccine in inflammatory bowel disease: a UK-wide study

OBJECTIVE

To investigate (1) the UK-wide inactivated influenza vaccine (IIV) uptake in adults with inflammatory bowel disease (IBD), (2) the association between vaccination against influenza and IBD flare and (3) the effectiveness of IIV in preventing morbidity and mortality.

DESIGN

Data for adults with IBD diagnosed before the 1 September 2018 were extracted from the Clinical Practice Research Datalink Gold. We calculated the proportion of people vaccinated against seasonal influenza in the 2018-2019 influenza cycle. To investigate vaccine effectiveness, we calculated the propensity score (PS) for vaccination and conducted Cox proportional hazard regression with inverse-probability treatment weighting on PS. We employed self-controlled case series analysis to investigate the association between vaccination and IBD flare.

RESULTS

Data for 13 631 people with IBD (50.4% male, mean age 52.9 years) were included. Fifty percent were vaccinated during the influenza cycle, while 32.1% were vaccinated on time, that is, before the seasonal influenza virus circulated in the community. IIV was associated with reduced all-cause mortality (aHR (95% CI): 0.73 (0.55,0.97) but not hospitalisation for pneumonia (aHR (95% CI) 0.52 (0.20-1.37), including in the influenza active period (aHR (95% CI) 0.48 (0.18-1.27)). Administration of the IIV was not associated with IBD flare.

CONCLUSION

The uptake of influenza vaccine was low in people with IBD, and the majority were not vaccinated before influenza virus circulated in the community. Vaccination with the IIV was not associated with IBD flare. These findings add to the evidence to promote vaccination against influenza in people with IBD.

Is Vaccination Against COVID-19 Associated With Inflammatory Bowel Disease Flare? Self-Controlled Case Series Analysis Using the UK CPRD

INTRODUCTION

To investigate the association between vaccination against coronavirus disease 2019 (COVID-19) and inflammatory bowel disease (IBD) flare.

METHODS

Patients with IBD vaccinated against COVID-19 who consulted for disease flare between December 1, 2020, and December 31, 2021, were ascertained from the Clinical Practice Research Datalink. IBD flares were identified using consultation and corticosteroid prescription records. Vaccinations were identified using product codes and vaccination dates. The study period was partitioned into vaccine-exposed (vaccination date and 21 days immediately after), prevaccination (7 days immediately before vaccination), and the remaining vaccine-unexposed periods. Participants contributed data with multiple vaccinations and IBD flares. Season-adjusted incidence rate ratios (aIRR) and 95% confidence intervals (CI) were calculated using self-controlled case series analysis.

RESULTS

Data for 1911 cases with IBD were included; 52% of them were female, and their mean age was 49 years. Approximately 63% of participants had ulcerative colitis (UC). COVID-19 vaccination was not associated with increased IBD flares in the vaccine-exposed period when all vaccinations were considered (aIRR [95% CI] 0.89 [0.77-1.02], 0.79 [0.66-0.95], and 1.00 [0.79-1.27] in IBD overall, UC, and Crohn's disease, respectively). Analyses stratified to include only first, second, or third COVID-19 vaccinations found no significant association between vaccination and IBD flares in the vaccine-exposed period (aIRR [95% CI] 0.87 [0.71-1.06], 0.93 [0.75-1.15], and 0.86 [0.63-1.17], respectively). Similarly, stratification by COVID-19 before vaccination and by vaccination with vectored DNA or messenger RNA vaccine did not reveal an increased risk of flare in any of these subgroups.

DISCUSSION

Vaccination against COVID-19 was not associated with IBD flares regardless of prior COVID-19 infection and whether messenger RNA or DNA vaccines were used.

Patients with IBD have a more cautious attitude towards COVID-19 vaccination

Background

To understand the awareness of COVID-19 vaccine, the willingness to vaccinate and the influencing factors of willingness to vaccinate in inflammatory bowel disease (IBD) patients.

Methods

The online questionnaire was distributed to conduct a survey to analyze and evaluate the willingness, awareness and trust in vaccines of IBD patients. Bivariate analyses and logistic regression models were used to analysis influencing factors.

Results

We sent the questionnaire to the WeChat group for patient management and 304 patients responded, out of which 16 respondents had to be excluded and 288 respondents were included for the analysis. Among them, 209 patients vaccinated with COVID-19 vaccine. Among the non-vaccinated 79 patients, the main reasons for their concerns were afraid of vaccination aggravating IBD and fear of adverse effects. Our results showed that IBD patients with long disease duration were more willing to receive COVID-19 vaccination (P<0.05). We also observed that a high perception of benefits and cues to action to receive the vaccine were the two most important constructs affecting a definite intention for COVID-19 vaccination (P<0.05).

Conclusions

Patients with IBD have a more cautious attitude towards COVID-19 vaccination, which may lead to a higher rate of vaccine hesitancy. Further efforts should be made to protect patients with IBD from COVID-19 infections and achieve adequate vaccination coverage.

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.

Evaluation of Safety and Immunogenicity of BNT162B2 mRNA COVID-19 Vaccine in IBD Pediatric Population with Distinct Immune Suppressive Regimens

Patients affected by Inflammatory Bowel Disease (IBD) present higher risk for infection and suboptimal response upon vaccination. The immunogenicity of SARS-CoV2 vaccination is still largely unknown in adolescents or young adults affected by IBD (pIBD). We investigated the safety and immunogenicity of the BNT162B2 mRNA COVID-19 vaccine in 27 pIBD, as compared to 30 healthy controls (HC). Immunogenicity was measured by anti-SARS-CoV2 IgG (anti-S and anti-trim Ab) before vaccination, after 21 days (T21) and 7 days after the second dose (T28). The safety profile was investigated by close monitoring and self-reported adverse events. Vaccination was well tolerated, and short-term adverse events reported were only mild to moderate. Three out of twenty-seven patients showed IBD flare after vaccination, but no causal relationship could be established. Overall, pIBD showed a good humoral response upon vaccination compared to HC; however, pIBD on anti-TNFα treatment showed lower anti-S Ab titers compared to patients receiving other immune-suppressive regimens (p = 0.0413 at first dose and p = 0.0301 at second dose). These data show that pIBD present a good safety and immunogenicity profile following SARS-CoV-2 mRNA vaccination. Additional studies on the impact of specific immune-suppressive regimens, such as anti TNFα, on immunogenicity should be further investigated on larger cohorts.

Health Care Maintenance in Patients with Crohn's Disease

Health care maintenance is critical for patients with inflammatory bowel disease (IBD), particularly for those receiving immunosuppressive medications. Vaccination recommendations for potentially preventable diseases, cancer prevention recommendations, and assessment of bone health and mood disorders are discussed in this article. Staying up to date with health care maintenance is of utmost importance, and all gastroenterologists caring for patients with IBD should be able to make recommendations regarding preventative care of these patients.
