- Immunogenicity decay and case incidence six months post Sinovac-CoronaVac vaccine in autoimmune rheumatic diseases patients(2022) SILVA, Clovis A.; MEDEIROS-RIBEIRO, Ana C.; KUPA, Leonard V. K.; YUKI, Emily F. N.; PASOTO, Sandra G.; SAAD, Carla G. S.; FUSCO, Solange R. G.; PEREIRA, Rosa M. R.; SHINJO, Samuel K.; HALPERN, Ari S. R.; BORBA, Eduardo F.; SOUZA, Fernando H. C.; GUEDES, Lissiane K. N.; MIOSSI, Renata; BONFIGLIOLI, Karina R.; DOMICIANO, Diogo S.; SHIMABUCO, Andrea Y.; ANDRADE, Danieli C. O.; SEGURO, Luciana P. C.; FULLER, Ricardo; SAMPAIO-BARROS, Percival D.; ASSAD, Ana P. L.; MORAES, Julio C. B.; GOLDENSTEIN-SCHAINBERG, Claudia; GIARDINI, Henrique A. M.; SILVA, Henrique C.; MARTINS, Victor A. O.; VILLAMARIN, Lorena E. B.; NOVELLINO, Renata S.; SALES, Lucas P.; ARAUJO, Carlo S. R.; SILVA, Matheus S. R.; FILHO, Dilson M. N.; LOPES, Marta H.; DUARTE, Alberto J. S.; KALLAS, Esper G.; AIKAWA, Nadia E.; BONFA, EloisaCharacterising the response to SARS-CoV-2 post vaccination is critical in the appraisement of the induced immune response, performance and protective potential. Here the authors present data from a phase 4 clinical trial in autoimmune rheumatic disease patients 6 months post second dose of Sinovac-CoronaVac inactivated vaccine that show a marked reduction in antibody particularly in males or those under treatment with immune targeting therapies but saw no rise in COVID-19 disease. The determination of durability and vaccine-associated protection is essential for booster doses strategies, however data on the stability of SARS-CoV-2 immunity are scarce. Here we assess anti-SARS-CoV-2 immunogenicity decay and incident cases six months after the 2(nd) dose of Sinovac-CoronaVac inactivated vaccine (D210) in 828 autoimmune rheumatic diseases patients compared with 207 age/sex-balanced control individuals. The primary outcome is the presence of anti-S1/S2 SARS-CoV-2 IgG at 6 months compared to 6 weeks after 2nd vaccine dose for decay evaluation. Secondary outcomes are presence of neutralizing antibodies, percent inhibition by neutralizing, geometric mean titers and cumulative incident cases at 6 months after 2nd dose. Anti-S1/S2 IgG positivity and titers reduce to 23.8% and 38% in patients (p < 0.001) during the six-month follow up and 20% and 51% in controls (p < 0.001), respectively. Neutralizing antibodies positivity and percent inhibition declines 41% and 54% in patients (p < 0.001) and 39.7% and 47% in controls (p < 0.001). Multivariate logistic regression analysis show males (OR = 0.56;95% CI0.40-0.79), prednisone (OR = 0.56; 95% CI0.41-0.76), anti-TNF (OR = 0.66;95% CI0.45-0.96), abatacept (OR = 0.29; 95% CI0.15-0.56) and rituximab (OR = 0.32;95% CI0.11-0.90) associate with a substantial reduction in IgG response at day 210 in patients. Although cellular immunity was not assessed, a decrease of COVID-19 cases (from 27.5 to 8.1/100 person-years; p < 0.001) is observed despite the concomitant emergence and spread of the Delta variant. Altogether we show a reduction in immunity 6-months of Sinovac-CoronaVac 2nd dose, particularly in males and those under immunosuppressives therapies, without a concomitant rise in COVID-19 cases.

- Increment of immunogenicity after third dose of a homologous inactivated SARS-CoV-2 vaccine in a large population of patients with autoimmune rheumatic diseases(2022) AIKAWA, Nadia Emi; KUPA, Leonard de Vinci Kanda; MEDEIROS-RIBEIRO, Ana Cristina; SAAD, Carla Goncalves Schahin; YUKI, Emily Figueiredo Neves; PASOTO, Sandra Gofinet; ROJO, Priscila Tagliaferro; PEREIRA, Rosa Maria Rodrigues; SHINJO, Samuel Katsuyuki; SAMPAIO-BARROS, Percival Degrava; ANDRADE, Danieli Castro Oliveira; HALPERN, Ari Stiel Radu; FULLER, Ricardo; SOUZA, Fernando Henrique Carlos; GUEDES, Lissiane Karine Noronha; ASSAD, Ana Paula Luppino; MORAES, Julio Cesar Bertacini de; LOPES, Michelle Remiao Ugolini; MARTINS, Victor Adriano de Oliveira; BETANCOURT, Lorena; RIBEIRO, Carolina Torres; SALES, Lucas Peixoto; BERTOGLIO, Isabela Maria; BONOLDI, Virginia Lucia Nazario; MELLO, Renata Lys Pinheiro; BALBI, Gustavo Guimaraes Moreira; SARTORI, Ana Marli Christovam; ANTONANGELO, Leila; SILVA, Clovis Artur; BONFA, EloisaObjective To determine the immunogenicity of the third dose of CoronaVac vaccine in a large population of patients with autoimmune rheumatic diseases (ARD) and the factors associated with impaired response. Methods Adult patients with ARD and age-balanced/sex-balanced controls (control group, CG) previously vaccinated with two doses of CoronaVac received the third dose at D210 (6 months after the second dose). The presence of anti-SARS-CoV-2 S1/S2 IgG and neutralising antibodies (NAb) was evaluated previously to vaccination (D210) and 30 days later (D240). Patients with controlled disease suspended mycophenolate mofetil (MMF) for 7 days or methotrexate (MTX) for 2 weekly doses after vaccination. Results ARD (n=597) and CG (n=199) had comparable age (p=0.943). Anti-S1/S2 IgG seropositivity rates significantly increased from D210 (60%) to D240 (93%) (p<0.0001) in patients with ARD. NAb positivity also increased: 38% (D210) vs 81.4% (D240) (p<0.0001). The same pattern was observed for CG, with significantly higher frequencies for both parameters at D240 (p<0.05). Multivariate logistic regression analyses in the ARD group revealed that older age (OR=0.98, 95% CI 0.96 to 1.0, p=0.024), vasculitis diagnosis (OR=0.24, 95% CI 0.11 to 0.53, p<0.001), prednisone >= 5 mg/day (OR=0.46, 95% CI 0.27 to 0.77, p=0.003), MMF (OR=0.30, 95% CI 0.15 to 0.61, p<0.001) and biologics (OR=0.27, 95% CI 0.16 to 0.46, p<0.001) were associated with reduced anti-S1/S2 IgG positivity. Similar analyses demonstrated that prednisone >= 5 mg/day (OR=0.63, 95% CI 0.44 to 0.90, p=0.011), abatacept (OR=0.39, 95% CI 0.20 to 0.74, p=0.004), belimumab (OR=0.29, 95% CI 0.13 to 0.67, p=0.004) and rituximab (OR=0.11, 95% CI 0.04 to 0.30, p<0.001) were negatively associated with NAb positivity. Further evaluation of COVID-19 seronegative ARD at D210 demonstrated prominent increases in positivity rates at D240 for anti-S1/S2 IgG (80.5%) and NAb (59.1%) (p<0.0001). Conclusions We provide novel data on a robust response to the third dose of CoronaVac in patients with ARD, even in those with prevaccination COVID-19 seronegative status. Drugs implicated in reducing immunogenicity after the regular two-dose regimen were associated with non-responsiveness after the third dose, except for MTX.
- Immunogenicity and safety of the CoronaVac inactivated vaccine in patients with autoimmune rheumatic diseases: a phase 4 trial(2021) MEDEIROS-RIBEIRO, Ana C.; AIKAWA, Nadia E.; SAAD, Carla G. S.; YUKI, Emily F. N.; PEDROSA, Tatiana; FUSCO, Solange R. G.; ROJO, Priscila T.; PEREIRA, Rosa M. R.; SHINJO, Samuel K.; ANDRADE, Danieli C. O.; SAMPAIO-BARROS, Percival D.; RIBEIRO, Carolina T.; DEVEZA, Giordano B. H.; MARTINS, Victor A. O.; SILVA, Clovis A.; LOPES, Marta H.; DUARTE, Alberto J. S.; ANTONANGELO, Leila; SABINO, Ester C.; KALLAS, Esper G.; PASOTO, Sandra G.; BONFA, EloisaCoronaVac, an inactivated SARS-CoV-2 vaccine, has been approved for emergency use in several countries. However, its immunogenicity in immunocompromised individuals has not been well established. We initiated a prospective phase 4 controlled trial (no. NCT04754698, CoronavRheum) in 910 adults with autoimmune rheumatic diseases (ARD) and 182 age- and sex-frequency-matched healthy adults (control group, CG), who received two doses of CoronaVac. The primary outcomes were reduction of >= 15% in both anti-SARS-CoV-2 IgG seroconversion (SC) and neutralizing antibody (NAb) positivity 6 weeks (day 69 (D69)) after the second dose in the ARD group compared with that in the CG. Secondary outcomes were IgG SC and NAb positivity at D28, IgG titers and neutralizing activity at D28 and D69 and vaccine safety. Prespecified endpoints were met, with lower anti-SARS-Cov-2 IgG SC (70.4 versus 95.5%, P < 0.001) and NAb positivity (56.3 versus 79.3%, P < 0.001) at D69 in the ARD group than in the CG. Moreover, IgG titers (12.1 versus 29.7, P < 0.001) and median neutralization activity (58.7 versus 64.5%, P = 0.013) were also lower at D69 in patients with ARD. At D28, patients with ARD presented with lower IgG frequency (18.7 versus 34.6%, P < 0.001) and NAb positivity (20.6 versus 36.3%, P < 0.001) than that of the CG. There were no moderate/severe adverse events. These data support the use of CoronaVac in patients with ARD, suggesting reduced but acceptable short-term immunogenicity. The trial is still ongoing to evaluate the long-term effectiveness/immunogenicity. In a large prospective phase 4 trial, vaccination with CoronaVac, an inactivated SARS-CoV-2 vaccine, elicited significantly lower virus-specific IgG antibodies and neutralizing antibodies in patients with autoimmune rheumatic diseases than in age- and sex-matched healthy control trial participants.
- Primary dental care treatment in primary Sjogren's syndrome: a possible role in improving salivary flow rate(2022) MARTINS, V. A. O.; FLORIANO, T. F.; LEON, E. P.; VILLAMARIN, L. E. B.; DEVEZA, G. B. H.; AIKAWA, N. E.; SILVA, C. A. A.; KUPA, L. V. K.; PERES, M. P. S. M.; BRAZ-SILVA, P. H.; BONFA, E.; PASOTO, S. G.Objective Primary Sjogren's syndrome (pSS) is an inflammatory chronic disorder that mainly affects exocrine glands. Additionally, oral infections can aggravate the glandular dysfunction. However, data on primary dental care (PDC) treatment in pSS are scarce. This study aimed to appraise the impact of PDC on the Xerostomia Inventory (XI), unstimulated/stimulated salivary flow rates and salivary cytokine profile in pSS. Methods Fifty-two pSS patients and 52 sex- and age-matched control participants without systemic autoimmune diseases were included in a prospective study. At inclusion, all participants were assessed through a standardised protocol, measurement of salivary pro-inflammatory cytokines, and underwent PDC. Dental procedures included: oral hygiene guidance, restorative treatment of caries, surgical removal of residual roots and impacted or partially erupted teeth, cysts, supra and subgingival periodontal scaling and treatment of soft tissue disorders (removal of lesions and treatment of opportunistic infections). After 3 months, the clinical/laboratorial assessments were repeated. Results At inclusion, the Decayed, Missing and Filled Teeth (DMFT) index was higher in the pSS patients than in the control group (13.3 +/- 8.2 vs. 8.6 +/- 6.2, p=0.002), whereas periodontal parameters were comparable in both groups (p>0.05). After PDC, 26.9% of pSS patients showed a reduction of at least 6 points (clinical improvement) in XI, but mean XI remained unchanged (p=0.285). PDC resulted in an increase in mean unstimulated (p<0.001) and stimulated (p=0.001) salivary flow rates in pSS, with no change in salivary cytokine profile (p=0.05). Conclusion PDC promoted improvement in unstimulated and stimulated salivary flow rates in pSS. This novel finding reinforces the recommendation of this strategy for pSS patients.

- Sjogren's syndrome and systemic lupus erythematosus: links and risks(2019) PASOTO, Sandra Gofinet; MARTINS, Victor Adriano de Oliveira; BONFA, EloisaSystemic lupus erythematosus (SLE) and Sjogren's syndrome (SS) may coexist, and they are chronic complex disorders, with an autoimmune background, multifactorial etiology, multiple circulating autoantibodies, and variable prognosis. The prominent feature of SS is the impairment of the lacrimal and salivary glands leading to sicca symptoms. This disease may be classified as primary Sjogren's syndrome (pSS), or secondary Sjogren's syndrome (sSS) since it is often associated to other autoimmune disorders, principally SLE, rheumatoid arthritis, and systemic sclerosis. Systematic reviews and meta-analyses show an sSS prevalence in SLE patients of about 14%-17.8%. Herein, we updated important aspects of the clinical association between SLE and sSS through a narrative review of the PubMed database in the last 5 years (from July 2013 to October 2018) with the terms ""Sjogren syndrome and systemic lupus erythematosus"". The following aspects are addressed: the classification criteria for sSS; differences and similarities between SLE and pSS regarding demographic, clinical, and serological characteristics (including new autoantibodies), as well as comorbidities; the etiopathogenic links between SLE and pSS (including genetic and environmental factors, B-cell activation, and autoantibodies); the predictive factors for sSS onset in SLE patients; the ocular and oral involvements due to sSS in SLE; and the main distinctive demographic, clinical, and serological features of SLE with and without associated SS.
