Higher and Sustained Cell-Mediated Immune Responses After 3 Doses of mRNA COVID-19 Vaccine in Patients With Inflammatory Bowel Disease on Anti-Tumor Necrosis Factor Therapy. Clin Transl Gastroenterol 2024; 15:e00688. [PMID: 38349178 PMCID: PMC11042770 DOI: 10.14309/ctg.0000000000000688] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/31/2023] [Accepted: 01/19/2024] [Indexed: 04/26/2024] Open
Abstract
INTRODUCTION Studies suggest that the generation of durable T-cell immunity following coronavirus disease 2019 (COVID-19) vaccination protects against severe disease. The aim of this study was to measure cell-mediated immune response (CMIR) 1-2 months and 6 months after a third dose of a COVID-19 mRNA vaccine. METHODS This prospective study (HumoRal and CellULar initial and Sustained immunogenicity in patients with inflammatory bowel disease [IBD]) evaluated CMIR at 28-65 days (t 1 ) after dose 2, 28-65 days (t 2 ) (n = 183) and 6 months (±45 days) (t 3 ) (n = 167) after a third dose of an mRNA COVID-19 vaccine. A small cohort had blood sample available 28-65 days (t 4 ) (n = 55) after a fourth dose. Primary outcomes were CMIR at (t 2 ) and (t 3 ). Secondary outcomes included the effect of immunosuppressing IBD medications on CMIR and response at (t 4 ). RESULTS All patients had measurable CMIR at all time points. CMIR increased at t 2 compared with that at t 1 (median 1,467 responding cells per million (interquartile range [IQR] 410-5,971) vs 313 (94-960) P < 0.001). There was no significant waning in t 2 vs t 3 or significant boosting at t 4 . Those on anti-tumor necrosis factor monotherapy had a higher CMIR compared with those not on this therapy at t 2 (4,132 [IQR 1,136-8,795] vs 869 [IQR 343-3,221] P < 0.001) and t 3 (2,843 [IQR 596-6,459] vs 654 [IQR 143-2,067] P < 0.001). In univariable analysis, anti-tumor necrosis factor monotherapy was associated with a higher CMIR at t 2 ( P < 0.001) and t 3 ( P < 0.001) and confirmed in a multivariable model ( P < 0.001). DISCUSSION A third dose of a COVID-19 vaccine boosts CMIR, and the response is sustained in patients with IBD.

Abstract
The COVID-19 pandemic introduced significant uncertainty regarding the care of patients with inflammatory bowel disease (IBD). Substantial research efforts have made progress in answering many of the questions that arose, but the constantly shifting paradigm of COVID-19-related research and recommendations has made it challenging for IBD clinicians to remain up-to-date. The goal of this article is to provide a concise and practical summary of the literature evaluating COVID-19 disease risk in addition to COVID-19 vaccine safety, immunogenicity, real-world effectiveness, and uptake among patients with IBD.

Abstract
Background: The emergence of new SARS-CoV-2 variants calls for more data on SARS-CoV-2 mRNA vaccine response. Aims: We aimed to assess the response to a third mRNA vaccine dose against SARS-CoV-2 in inflammatory bowel disease (IBD) patients. Methods: This was a single-center, observational prospective study of IBD patients who received a third mRNA vaccine dose against SARS-CoV-2. Antibody titers were taken post-third-dose at one and three months using the Roche Elecsys anti-SARS-CoV-2-S enzyme immunoassay. Titers less than 0.8 units/mL were considered negative according to the manufactures. Titers between 0.8 units/mL and 250 units/mL were considered non-neutralizing. Titers greater than 250 units/mL were considered neutralizing. Results: Eighty-three patients were included, all of whom had detectable antibodies at 3 months post-third dose. A total of 89% showed neutralizing and 11% non-neutralizing titers. Participants with non-neutralizing titers were more likely to be on systemic corticosteroids (p = 0.04). Two participants seroconverted from negative to positive, whereas 86% with non-neutralizing titers boosted to neutralizing levels. Only one participant with neutralizing titers after a third dose had a decrease to a non-neutralizing level within 3 months. Conclusions: Our findings support the ongoing recommendations for additional doses in immunocompromised individuals. However, longitudinal studies with a greater-sized patient population are needed.

Abstract
Patients with inflammatory bowel disease (IBD) are not at increased risk of SARS-CoV-2 infection compared to the general population, and most are not at increased risk for severe disease. COVID-19 is nonetheless common, and vaccination is critical. Four safe and efficacious vaccines are now available for the prevention of COVID-19, with most data available for mRNA vaccines. Patients with IBD have a robust humoral response to vaccination with rates of seroconversion exceeding 95% following a two-dose mRNA vaccine series and 99% following a three-dose mRNA series, although those on certain therapies including anti-tumor necrosis factor α agents may have lower antibody concentrations and waning of antibodies over time. Additionally, rates of cell-mediated immune response, even in those patients with IBD who did not have evidence of humoral immunity, are high. Vaccines are safe and have not been associated with flares in disease activity. Gastroenterology providers should take an active role in ensuring patients with IBD are appropriately vaccinated against COVID-19.

Abstract
BACKGROUND Immunosuppressed patients with inflammatory bowel disease (IBD) experience increased risk of vaccine-preventable diseases such as COVID-19. AIMS To assess humoral and cellular immune responses following SARS-CoV-2 booster vaccination in immunosuppressed IBD patients and healthy controls. METHODS In this prospective, multicentre, case-control study, 139 IBD patients treated with biologics and 110 healthy controls were recruited. Serum anti-SARS-CoV-2 spike IgG concentrations were measured 2-16 weeks after receiving a third mRNA vaccine dose. The primary outcome was to determine if humoral immune responses towards booster vaccines differ in IBD patients under anti-TNF versus non-anti-TNF therapy and healthy controls. Secondary outcomes were antibody decline, impact of previous infection and SARS-CoV-2-targeted T cell responses. RESULTS Anti-TNF-treated IBD patients showed reduced anti-spike IgG concentrations (geometric mean 2357.4 BAU/ml [geometric SD 3.3]) when compared to non-anti-TNF-treated patients (5935.7 BAU/ml [3.9]; p < 0.0001) and healthy controls (5481.7 BAU/ml [2.4]; p < 0.0001), respectively. In multivariable modelling, prior infection (geometric mean ratio 2.00 [95% CI 1.34-2.90]) and vaccination with mRNA-1273 (1.53 [1.01-2.27]) increased antibody concentrations, while anti-TNF treatment (0.39 [0.28-0.54]) and prolonged time between vaccination and antibody measurement (0.72 [0.58-0.90]) decreased anti-SARS-CoV-2 spike antibodies. Antibody decline was comparable in IBD patients independent of anti-TNF treatment and antibody concentrations could not predict breakthrough infections. Cellular and humoral immune responses were uncoupled, and more anti-TNF-treated patients than healthy controls developed inadequate T cell responses (15/73 [20.5%] vs 2/100 [2.0%]; p = 0.00031). CONCLUSIONS Anti-TNF-treated IBD patients have impaired humoral and cellular immunogenicity following SARS-CoV-2 booster vaccination. Fourth dose administration may be beneficial for these patients.
