ABSTRACT
Objectives: To evaluate vaccination among patients with inflammatory rheumatic diseases initiating disease-modifying antirheumatic drugs (DMARD) Methods: Data from the real-world life PANLAR's register of consecutive patients diagnosed with RA, PsA, and axSpa (2010 ACR-EULAR /2006 CASPAR-2009 ASAS) from Dec 2021 to Dec 2022 were analyzed. Prevalence of recommended vaccinations were compared between different inflammatory rheumatic diseases. Categorical variables were expressed as %. Tables were analyzed with chi2 or Fisher tests, continuous variables (median, IQR)with the Kruskal-Wallis test, according with the variables type. A p value <=0.05 was considered significant. Result(s): 608 patients were included. Among patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA), and axial Spondyloarthritis (axSpA) are presented in the table. RA and axSpA seemed to have lower vaccination rate of pneumococcal vaccines than PsA. (p = 0.045 for conjugate anti pneumococcal vaccine in RA vs PsA). A large percentage of the population was vaccinated against COVID-19. There was a high rate of influenza vaccination in all three diseases. Conclusion(s): In Latin America, anti-pneumococcal vaccination is low, especially in patients with RA and axSpA. For other vaccines there was an acceptable level of vaccination without differences between diseases.
ABSTRACT
Background: We recently reported an attenuate immunogenicity in patients with autoimmune rheumatic diseases. However, the effect of spondyloarthritis (SpA) and its treatment on COVID-19 vaccine immunogenicity remains to be determined for this group of patients. We therefore aimed to evaluate humoral immune responses to inactivated SARS-CoV-2 vaccine (CoronaVac) in patients with SpA (axial spondyloarthritis and psoriatic arthritis) taking DMARDs and commonly used targeted biological therapies, compared with a control group(CG). Objectives: Evaluate immunogenicity and safety of CORONAVAC (Sninovac, Beijing) in Spondyloarthritis (SpA) patients. Methods: Prospective observational cohort patients diagnosed with 194 SpA and 183 CG were vaccinated with CoronaVac in two doses with a 28-days interval. 194 patients completed the study and could be paired with CG for immunogenicity analysis. Blood samples were collected in the days 0, 28 and 69 (D69) to evaluate anti-SARS-CoV-2 IgG seroconversion(SC) and presence of neutralizing antibodies (NAb) in participants with negative IgG and NAb at baseline. Results: Patients and GC were comparable regarding age (p=0.93) and sex (p=1.00). Immunogenicity at D69 showed a moderate/high SC (80.2% vs. 95.7%, p<0.0001) and Nab positivity (61.6% vs. 82.7%, p<0.0001) in SpA but lower than CG. Factors associated with lower immunogenicity were older age (56.8 vs. 51.4;p=0.03318) and higher frequencies of prednisone (25.7% vs 4.2%;p=0.0004), methotrexate (51.4% vs 40.1%, p=0.0016) and TNF inhibitor (TNFi) (62.9% vs 34.5%, p=0.0035). Likewise, prednisone (17.6% vs. 2.8%, p=0.0013) and TNFi (50% vs 33.9%;p=0.0408) were associated with diminished NAb positivity. Sulfasalazine was associated with higher SC rates (8.6% vs. 26.8%, p=0.0246) and NAb positivity (13.2% vs. 29.4%, p=0.0168). The multivariate analysis revealed that older age (p=0.037), prednisone (p=0.001), TNFi (p=0.016), and methotrex-ate(p=0.017) were independently associated with lower SC while prednisone (p=0.006) and TNFi (p=0.027) were also associated with reduced NAb response. Conclusion: Our fnding of an excellent safety and moderate/high SC rate in SpA supports the recommendation of CoronaVac vaccination. The impaired immune response in the minority of patients under immunosuppressive and biological therapy requires novel strategies to enhance antibody response in this subgroup of patients.
ABSTRACT
Background: Patients with rheumatoid arthritis (RA) on methotrexate have reduced vaccine responses. Temporary discontinuation has improved immuno-genicity of anti-infuenza vaccine, but this strategy has not been evaluated in anti-SARS-CoV-2 vaccines. Objectives: To evaluate the effect on immunogenicity and safety of 2-week methotrexate (MTX) discontinuation after each dose of the Sinovac-CoronaVac vaccine versus MTX maintenance in rheumatoid arthritis (RA) patients. Methods: This was a single-center, prospective, randomized, investigator-blinded, intervention study (#NCT04754698, CoronavRheum), including adult RA patients (stable CDAI≤10, prednisone ≤7.5mg/day), randomized (1:1) to withdraw MTX (MTX-hold) for 2 weeks after each vaccine dose or maintain MTX (MTX-maintain), evaluated at D0, D28 and D69. Co-primary outcomes were anti-SARS-CoV-2 S1/S2 IgG seroconversion(SC) and neutralizing antibody (NAb) positivity at D69. Secondary outcomes were geometric mean titers (GMT) and fare rates. For immunogenicity analyses, we excluded patients with baseline positive IgG/NAb, and, for safety reasons, those who fared at D28 (CDAI>10) and did not withdraw MTX twice. Results: Randomization included 138 patients with 9 exclusions (5 COVID-19, 4 protocol violations). Safety evaluation included 60 (MTX-hold) and 69 (MTX-maintain) patients. Further exclusions: 27 patients [13 (21.7%) vs. 14 (20.3%), p=0.848] with positive baseline IgG/NAb and 10 patients (21.3%) in MTX-hold with CDAI>10 at D28. At D69, MTX-hold (n=37) had a higher rate of seroconversion than MTX-maintain (n=55) group [29 (78.4%) vs 30 (54.5%), p=0.019], with parallel augmentation in GMT [34.2 (25.2-46.4) vs 16.8 (11.9-23.6), p=0.006]. No differences were observed for NAb positivity [23 (62.2%) vs 27 (49.1%), p=0.217]. At D28 fare, rates were comparable in both groups (CDAI, p=0.122;DAS28-CRP, p=0.576), whereas CDAI>10 was more frequent in MTX-hold at D69 (p=0.024). Conclusion: We provide novel data that 2-week MTX withdrawal after each Sinovac-CoronaVac vaccine dose improves anti-SARS-CoV-2 IgG response. The increased fare rates after second MTX withdrawal may be attributed to the short-term interval between vaccine doses. This strategy requires close surveillance and shared decision making due to the possibility of fares.
ABSTRACT
Background: The SARS-CoV-2 virus has caused a worldwide health crisis. Patients with infammatory arthritis are at higher risk of hospitalization and death by COVID-19 due to comorbidities or immunosuppressive treatments. Vaccination is one the most important strategies to control the pandemic. Objectives: To evaluate the incident cases of SARS-CoV-2 infection in a multi-centric cohort of infammatory arthritis in Brazil. Methods: BiobadaBrasil is a multicentric registry-based cohort study of Brazilian patients with rheumatic diseases starting their frst bDMARD or tsDMARD (1). The present analysis is a retrospective evaluation of adult patients with infam-matory arthritis (rheumatoid arthritis-RA, spondylarthritis-SpA and psoriatic arthritis-PsA) that were alive since the beginning of the COVID-19 pandemics in Brazil in February 2020. We evaluated the incidence and severity of COVID-19 infection and the adherence to anti-SARS-CoV-2 vaccines schedules, up to January 2022. Results: A total of 300 patients were interviewed and 69 (23.0%) reported con-frmed anti-SARS-CoV infection and 5 (1.7%) had a second infection. Among known infected patients, 18.8% need hospitalization and oxygen support, 7.2% were admitted at ICU, and 5.8% died. After COVID-19 infection, 31.8% reported worsening of disease activity but only 6.1% had modifcation in medication due to disease activity. Distribution of cases followed the pattern of waves observed in Brazil (Figure 1). Regarding vaccination, 285 (95%) reported to have received at least one dose of any anti-SARS-CoV-2 vaccine: 43% received the frst with the adenovirus ChAdOx1 nCoV-19 (AstraZeneca) adenovirus vaccine, 32% received the Sinovac-CoronaVac inactivated vaccine, 22% received the BNT162b2 (Pfzer-BioNtech) mRNA vaccine and 3% received the BNT162b2 (Pfzer-BioNtech) adenovirus vaccine. Almost all (98.1%) of these patients had already received the second dose of vaccine and after the frst and second vaccine doses, 6% and 4% of patients, respectively, reported worsening of articular disease activity, while, after the third dose, no patient reported disease activity worsening. Conclusion: During the pandemics, patients with infammatory arthritis had a pattern of distribution of cases very similar to general population. Adherence to vaccination is high and well tolerated.
ABSTRACT
Background: Arthritis by Paracoccidioides brasiliensis is a remarkably unusual etiology of infectious joint disease. While osseous lesions can be present in systemic disease, intra-articular-restricted disease without typical lung or lymph node involvement is mostly anecdotal1,2. Objectives: We hereby describe a case of this fungal arthritis in a patient with rheumatoid arthritis (RA) without signifcant immunosuppression. Methods: Patient records review. Written informed consent was obtained. Results: A 65-year-old female Brazilian patient with a 35-year history of seropositive RA complained of a painful knee edema for the last three weeks. Skin surrounding the joint was erythematous, warm, and tender to the touch, which initially raised the suspicion of cellulitis. She had already received a 10-day course of amoxicillin-clavulanate, with no improvement. C-reactive protein was 17.8 mg/L, rest of blood chemistry panel was within reference range. Point-of-care ultrasound revealed joint effusion, and a diagnostic arthrocentesis was performed. Synovial fluid was slightly turbid, with 10,100 cells per mm3, of which 80% were lymphocytes. Cultures for bacteria and mycobacteria yielded negative results, but culture for fungi detected growth of P. brasiliensis. The patient had been solely on prednisone 5 mg once daily for the last year, given that, due to covid-19 pandemics, she lost regular follow-up and abandoned treatment with immunosuppressants. Aside from mild RA-related interstitial lung disease, she had no other comorbidity. She denied local trauma to the knee, which made hematogenous dissemination of the fungi the most probable source. Comprehensive work-up to search for organic involvement of paracoccid-ioidomycosis, including chest computed tomography and transthoracic echocardiogram, did not evidence any visceral compromise. Voricona-zole 200mg t.i.d. was started, with good response. Three months after the beginning of the azole, tofacitinib was started for moderate RA disease activity, which also responded satisfactorily. Repeat arthrocentesis and synovial biopsy were performed eight months after the start of antifun-gal treatment, the former being normal (770 cells per mm3, negative cultures), and the later only demonstrating non-specific chronic synovitis with fibrosis. Conclusion: We reported an exceedingly rare presentation of P. brasiliensis infection with exclusive joint involvement.
