IntroductionVaccination represents a cornerstone in mastering the COVID-19 pandemic. Data on immunogenicity and safety of messenger RNA (mRNA) vaccines in patients with autoimmune inflammatory rheumatic diseases (AIIRD) are limited.MethodsA multicentre observational study evaluated the immunogenicity and safety of the two-dose regimen BNT162b2 mRNA vaccine in adult patients with AIIRD (n=686) compared with the general population (n=121). Serum IgG antibody levels against SARS-CoV-2 spike S1/S2 proteins were measured 2–6 weeks after the second vaccine dose. Seropositivity was defined as IgG ≥15 binding antibody units (BAU)/mL. Vaccination efficacy, safety, and disease activity were assessed within 6 weeks after the second vaccine dose.ResultsFollowing vaccination, the seropositivity rate and S1/S2 IgG levels were significantly lower among patients with AIIRD versus controls (86% (n=590) vs 100%, p<0.0001 and 132.9±91.7 vs 218.6±82.06 BAU/mL, p<0.0001, respectively). Risk factors for reduced immunogenicity included older age and treatment with glucocorticoids, rituximab, mycophenolate mofetil (MMF), and abatacept. Rituximab was the main cause of a seronegative response (39% seropositivity). There were no postvaccination symptomatic cases of COVID-19 among patients with AIIRD and one mild case in the control group. Major adverse events in patients with AIIRD included death (n=2) several weeks after the second vaccine dose, non-disseminated herpes zoster (n=6), uveitis (n=2), and pericarditis (n=1). Postvaccination disease activity remained stable in the majority of patients.ConclusionmRNA BNTb262 vaccine was immunogenic in the majority of patients with AIIRD, with an acceptable safety profile. Treatment with glucocorticoids, rituximab, MMF, and abatacept was associated with a significantly reduced BNT162b2-induced immunogenicity.
Objective. To assess the magnitude of risk of cardiovascular and cerebrovascular morbidity in patients with psoriatic arthritis (PsA) compared with the general population through a systematic review and meta-analysis of observational studies. Methods. We searched the Medline, Embase, and Cochrane databases, as well as abstracts archives from rheumatology conferences. Observational studies that included a PsA diagnosis, cardiovascular or cerebrovascular outcomes, and a comparison group of individuals without psoriasis and rheumatic diseases and were case-control, crosssectional, or cohort studies, were assessed by 2 researchers. We calculated weighted pooled summary estimates of the maximally adjusted effect size estimates for cardiovascular and cerebrovascular diseases using the random-effects model, and tested for heterogeneity using the I 2 statistic. Results. Eleven studies, comprising 32,973 patients with PsA, met the inclusion criteria. There was a 43% increased risk of cardiovascular diseases in patients with PsA compared with the general population (pooled odds ratio [OR] 1.43 [95% confidence interval (95% CI) 1.24-1.66]). The risk of incident cardiovascular events was increased by 55% (pooled OR 1.22-1.96). Morbidity risks for myocardial infarction, cerebrovascular diseases, and heart failure were increased by 68%, 22%, and 31%, respectively (pooled OR 1.68 [95% CI 1.31-2.15], pooled OR 1.22 [95% CI 1.05-1.41], and pooled OR 1.31 [95% CI 1.11-1.55], respectively). We identified significant heterogeneity in all main analyses (P < 0.001). Conclusion. Cardiovascular and cerebrovascular morbidity are increased by 43% and 22%, respectively, in patients with PsA compared with the general population.
A preclinical phase exists in patients with PsA prior to the diagnosis of the disease. This phase is characterized by nonspecific musculoskeletal symptoms, including joint pain, fatigue, and stiffness.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
