Low incidence and transient elevation of autoantibodies post mRNA COVID-19 vaccination in inflammatory arthritis.

ABSTRACT:

Objectives

Autoantibody seroconversion has been extensively studied in the context of COVID-19 infection but data regarding post-vaccination autoantibody production is lacking. Here we aimed to determine the incidence of common autoantibody formation following mRNA COVID-19 vaccines in patients with inflammatory arthritis (IA) and in healthy controls.

Methods

Autoantibody seroconversion was measured by serum ELISA in a longitudinal cohort of IA participants and healthy controls before and after COVID-19 mRNA-based immunization.

Results

Overall, there was a significantly lower incidence of ANA seroconversion in participants who did not contract COVID-19 prior to vaccination compared with those who been previously infected (7.4% vs 24.1%, p= 0.014). Incidence of de novo anti-cyclic citrullinated protein (CCP) seroconversion in all participants was low at 4.9%. Autoantibody levels were typically of low titer, transient, and not associated with increase in IA flares.

Conclusions

In both health and inflammatory arthritis, the risk of autoantibody seroconversion is lower following mRNA-based immunization than following natural SARS-CoV-2 infection. Importantly, seroconversion does not correlate with self-reported IA disease flare risk, further supporting the encouragement of mRNA-based COVID-19 immunization in the IA population.

Project description:Background and aimsExtraintestinal manifestations [EIMs] such as arthritis/arthralgia are common in inflammatory bowel disease. We performed post hoc analyses of data from the GEMINI studies to evaluate the effect of vedolizumab, a gut-selective anti-trafficking agent, on arthritis/arthralgia.MethodsSustained resolution of baseline arthritis/arthralgia, worsening of baseline arthritis/arthralgia, the occurrence of new arthritis/arthralgia, and the composite of new/worsening arthritis/arthralgia were evaluated. Cox modelling was used for time-to-event analysis. The influence of corticosteroid-tapering was also investigated.ResultsIn Crohn's disease [CD] patients, vedolizumab was significantly less likely than placebo to be associated with new/worsening arthritis/arthralgia (hazard ratio [HR], 0.63; 95% confidence interval [CI], 0.44-0.89). Similar incidences of sustained resolution of arthritis/arthralgia occurred with vedolizumab and placebo. In CD patients on corticosteroids at baseline, a decrease in corticosteroid dose increased the risk of new/worsening arthritis/arthralgia (odds ratio [OR], 7.49; 95% CI, 3.50-15.97) regardless of treatment; and in those achieving corticosteroid-free status, arthritis/arthralgia was less likely with vedolizumab than with placebo [HR, 0.14; 95% CI, 0.05-0.35]. In ulcerative colitis [UC] patients, vedolizumab and placebo showed a similar incidence of new/worsening of arthritis/arthralgia. In UC patients on corticosteroid at baseline, arthritis/arthralgia was more likely in those achieving corticosteroid-free status than in those continuing corticosteroids (HR 2.63 [95% CI 1.13-6.11]); and in those achieving corticosteroid-free status, the incidence of arthritis/arthralgia was similar with vedolizumab and placebo.ConclusionsVedolizumab therapy was associated with a reduced likelihood of new/worsening arthritis/arthralgia in CD and no increased incidence of these events in UC.Studies included [clincialtrials.gov, number]GEMINI 1 [NCT00783718]; GEMINI 2 [NCT00783692]; GEMINI 3 [NCT01224171].

Project description:IntroductionAnti-citrullinated protein/peptide antibodies (ACPAs) are highly specific to rheumatoid arthritis (RA) patients and are thought to have a close relationship with the pathogenesis of arthritis. Several proteins, including fibrinogen, vimentin, and alpha-enolase, were reported as ACPA-target antigens, and their importance in RA pathogenesis was widely proposed. We identified citrullinated immunoglobulin binding protein (citBiP) as another ACPA target in RA patients and examined its pro-inflammatory role in arthritis.MethodsWe measured the levels of anti-citBiP, anti-BiP, and anti-cyclic citrullinated peptide (CCP) antibodies in the serum of RA patients (n = 100), systemic lupus erythematosus (SLE) patients (n = 60), and healthy controls (n = 30) using ELISA and immunoblotting. Epitope mapping was performed using 27 citBiP-derived peptides. In the mouse study, after DBA/1J mice were immunized with BiP or citBiP, serum titers of ACPAs were measured by ELISA and immunohistochemistry. The development of collagen-induced arthritis (CIA) was observed in BiP- or citBiP-pre-immunized mice.ResultsThe serum levels of anti-BiP and anti-citBiP antibodies were significantly increased in RA patients, although only anti-BiP antibodies were slightly increased in SLE patients. Interestingly, anti-citBiP antibody levels were higher than anti-BiP antibody levels in 72% of RA patients, whereas no significant increase in anti-citBiP antibody levels was detected in SLE patients and healthy controls. The serum levels of anti-CCP antibodies were correlated with those of anti-citBiP antibodies in RA patients (R2 = 0.41). Several citrulline residues of citBiP were determined to be major epitopes of anti-citBiP antibodies, one of which showed cross-reactivity with CCP. Immunization of DBA/1J mice with citBiP induced several kinds of ACPAs, including anti-CCP and anti-citrullinated fibrinogen antibodies. Pre-immunization with citBiP exacerbated CIA, and anti-CCP antibody levels were increased in citBiP-pre-immunized CIA mice.ConclusionsCitBiP is a newly described ACPA target that may play a pro-inflammatory role in arthritis.
