Data assessing immunogenicity and safety of this virus component are lacking in systemic lupus erythematosus (SLE) and restricted to small reports with other H3N2 strains. Objective This study aims to evaluate short-term immunogenicity and safety of influenza A/Singapore (H3N2) vaccine in SLE. Methods 81 consecutive SLE patients and 81 age- and sex-matched healthy controls (HC) were vaccinated with the influenza A/Singapore/INFIMH-16-0019/2016(H3N2)-like virus. Seroprotection (SP) and seroconversion (SC) rates, geometric mean titers(GMT), and factor increase in GMT(FI-GMT) and adverse events were assessed before and 4 weeks post-vaccination. Disease activity and therapies were also evaluated. Results Before immunization, SLE and HC groups had high SP rates (89% vs 77%, p = 0.061) and elevated GMT titer with higher levels in SLE (129.1(104.1-154.1) vs 54.8(45.0-64.6), p < 0.001). Frequency of two previous years' influenza vaccination was high and comparable in SLE and HC (89% vs 90%, p = 1.000). Four weeks post-vaccination, median GMT increased for both groups and remained higher in SLE compared to HC (239.9(189.5-290.4) vs 94.5(72.6-116.4), p < 0.0001) with a comparable FI-GMT (2.3(1.8-2.9) vs 1.9(1.5-2.3), p = 0.051). SC rates were low and comparable for both groups (16% vs 11%, respectively, p = 0.974). Disease activity scores remained stable throughout the study (p = 1.000) and severe adverse events were not identified. Conclusion Influenza A/Singapore (H3N2) vaccine has an adequate safety profile. The distinct immunogenicity pattern from other influenza A components characterized by a remarkably high pre- and post-vaccination SP rate and high GMT levels may be associated with previous influenza A vaccination.

- Yellow fever vaccination in Brazil: Short-term safety and immunogenicity in juvenile autoimmune rheumatic diseases(2022) AIKAWA, Nadia Emi; BALBI, Verena Andrade; BORBA, Eduardo Ferreira; TONACIO, Adriana Coracini; SALLUM, Adriana Maluf Elias; CAMPOS, Lucia Maria Arruda; KOZU, Katia Tomie; VENDRAMINI, Margarete Borges; FONTOURA, Nicole; AZEVEDO, Adriana de Souza; SCHWARCZ, Waleska Dias; SARTORI, Ana Marli Christovam; ANTONANGELO, Leila; SILVA, Clovis Artur; BONFA, EloisaYellow fever vaccine (YFV) is a live attenuated vaccine usually contraindicated for juvenile autoimmune rheumatic disease (JARD) patients. During the recent epidemic in Sao Paulo-Brazil, YFV was indicated for patients under low immunosuppression. Thirty JARD patients with inactive diseases undergoing low immunosuppression and 30 healthy controls (HC) were vaccinated with a fractional dose 17DD YFV (similar to 5495 IU) and evaluated 30 days later. JARD patients and controls had comparable median age (12.4 vs. 12 years, p = 0.250). Disease parameters remained stable 30 days after 17DD YFV (p > 0.05) and only mild adverse events were reported in both groups (p > 0.05). JARD and HC had similar seroprotection [93% vs. 100%;p = 0.49], seroconversion rates [96% vs. 100%;p = 0.489], and GMT [1249 vs.1293; p = 0.821]. Both groups had similar white-blood-cells kinetics with transient decreases in lymphocytes at D5 and neutrophils at D10, followed by full recovery at D30 (P < 0.05). In conclusion, 17DD YFV was safe and immunogenic in JARD. This study may contribute to recommendations for patients living/travelling to endemic areas. (C) 2021 The Authors.
- Immunogenicity and safety of two doses of the CoronaVac SARS-CoV-2 vaccine in SARS-CoV-2 seropositive and seronegative patients with autoimmune rheumatic diseases in Brazil: a subgroup analysis of a phase 4 prospective study(2022) AIKAWA, Nadia E.; KUPA, Leonard V. K.; PASOTO, Sandra G.; MEDEIROS-RIBEIRO, Ana C.; YUKI, Emily F. N.; SAAD, Carla G. S.; PEDROSA, Tatiana; FULLER, Ricardo; SHINJO, Samuel K.; SAMPAIO-BARROS, Percival D.; ANDRADE, Danieli C. O.; PEREIRA, Rosa M. R.; SEGURO, Luciana P. C.; VALIM, Juliana M. L.; WARIDEL, Filipe; SARTORI, Ana Marli C.; DUARTE, Alberto J. S.; ANTONANGELO, Leila; SABINO, Ester C.; MENEZES, Paulo Rossi; KALLAS, Esper G.; SILVA, Clovis A.; BONFA, EloisaBackground We aimed to examine the immunogenicity pattern induced by the inactivated SARS-CoV-2 vaccine CoronaVac (Sinovac Life Sciences, Beijing, China) in SARS-CoV-2 seropositive patients with autoimmune rheumatic diseases compared with seropositive controls, seronegative patients with autoimmune rheumatic diseases, and seronegative controls. Methods CoronavRheum is an ongoing, prospective, controlled, phase 4 study, in which patients aged 18 years or older with autoimmune rheumatic diseases, and healthy controls were recruited from a single site (Rheumatology Division of Hospital das Clinicas, Faculdade de Medicina da Universidade de Sao Paulo) in Sao Paulo, Brazil Participants were vaccinated with two doses of CoronaVac (intramuscular injection, 3 mu g in 0middot5 mL of beta-propiolactone inactivated SARSCoV-2) on day 0 and on day 28. Blood samples were taken pre-vaccination on day 0, day 28, and also on day 69. For this subgroup analysis, participants were defined as being SARS-CoV-2 seropositive or seronegative prevaccination via anti-SARS-CoV-2 spike (S)1 or S2 IgG (cutoff of 15middot0 arbitrary units [AU] per mL) or neutralising antibody titres (cutoff of >= 30%) and were matched for age and sex, via convenience sampling, in a 1:3:1:1 ratio (seropositive patients to seronegative patients to seropositive controls to seronegative controls). The primary outcomes were rates of anti-SARSCoV-2 S1 and S2 IgG seropositivity and SARS-CoV-2 neutralising antibody positivity at day 28 and day 69 and immunogenicity dynamics assessed by geometric mean titres (GMTs) of IgG and median neutralising activity in seropositive patients with autoimmune rheumatic diseases compared with seronegative patients and seropositive and seronegative controls. We assessed safety in all participants randomly selected for this subgroup analysis. This study is registered with ClinicalTrials.gov, NCT04754698, and is ongoing for long-term immunogenicity evaluation. Findings Between Feb 4 and Feb 8, 2021, 1418 patients and 542 controls were recruited, of whom 1685 received two vaccinations (1193 patients and 492 controls). After random sampling, our immunogenicity analysis population comprised 942 participants, of whom 157 were SARS-CoV-2 seropositive patients with autoimmune rheumatic diseases, 157 were seropositive controls, 471 were seronegative patients, and 157 were seronegative controls; the median age was 48 years (IQR 38-56) and 594 (63%) were female and 348 (37%) were male. For seropositive patients and controls, an increase in anti-SARS-CoV-2 S1 and S2 IgG titres (seropositive patients GMT 52middot3 [95% CI 42middot9-63middot9] at day 0 vs 128middot9 [105middot6-157middot4] at day 28; seropositive controls 53middot3 [45middot4-62middot5] at day 0 vs 202middot0 [174middot8-233middot4] at day 28) and neutralising antibody activity (seropositive patients 59% [IQR 39-83] at day 0 vs 82% [54-96] at day 28; seropositive controls 58% [41-79] at day 0 vs 92% [79-96] at day 28), was observed from day 0 to day 28, without further increases from day 28 to day 69 (at day 69 seropositive patients' GMT was 137middot1 [116middot2-161middot9] and neutralising antibody activity was 79% [57-94]); and seropositive controls' GMT was 188middot6 [167middot4-212middot6] and neutralising antibody activity was 92% [75-96]). By contrast, for seronegative patients and controls, the second dose was required for maximum response at day 69, which was lower in seronegative patients than in seronegative controls. GMTs in seronegative patients were 2middot3 (95% CI 2middot2-2middot3) at day 0, 5middot7 (5middot1-6middot4) at day 28, and 29middot6 (26middot4-33middot3) at day 69, and in seronegative controls were 2middot3 (2middot1-2middot5) at day 0, 10middot6 (8middot7-13middot1) at day 28, and 71middot7 (63middot5-81middot0) at day 69; neutralising antibody activity in seronegative patients was 15% (IQR 15-15) on day 0, 15% (15-15) at day 28, and 39% (15-65) at day 69, and in seronegative controls was 15% (15-15) at day 0, 24% (15-37) at day 28, and 61% (37-79) at day 69. Neither seronegative patients nor seronegative controls reached the GMT or antibody activity levels of seropositive patients at day 69. Interpretation By contrast with seronegative patients with autoimmune rheumatic diseases, seropositive patients have a robust response after a single dose of CoronaVac. Our findings raise the possibility that the reduced immunogenicity observed in seronegative patients might not be the optimum response potential to SARS-CoV-2 vaccination, and therefore emphasise the importance of at least a single booster vaccination in these patients.
- 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.
conferenceObject Influenza A(H3N2)/Singapore Component Vaccine in Systemic Lupus Erythematosus: A Distinct Pattern of Immunogenicity(2021) FORMIGA, Francisco Fellipe Claudino; SILVA, Clovis Artur; PEDROSA, Tatiana do Nascimento; AIKAWA, Nadia; GARCIA, Cristiana Couto; CAPAO, Artur; MARTINS, Victor Adriano de Oliveira; PROENCA, Adriana Coracini Tonacio de; FULLER, Ricardo; YUKI, Emily Figueiredo Vieira Neves; VENDRAMINI, Margarete Borges Galhardo; ROSARIO, Debora Cordeiro do; BRANDAO, Leticia Maria Kolachinski Raposo; SARTORI, Ana Marli Christovam; PASOTO, Sandra Gofinet; ANTONANGELO, Leila; BONFA, Eloisa; BORBA, Eduardo Ferreira- TNF blockers show distinct patterns of immune response to the pandemic influenza A H1N1 vaccine in inflammatory arthritis patients(2012) FRANCA, Ivan Leonardo Avelino; RIBEIRO, Ana Cristina Medeiros; AIKAWA, Nadia Emi; SAAD, Carla Goncalves Schain; MORAES, Julio Cesar Bertacine; GOLDSTEIN-SCHAINBERG, Claudia; LAURINDO, Ieda Maria Magalhaes; PRECIOSO, Alexander Roberto; ISHIDA, Maria Akiko; SARTORI, Ana Marli Christovam; SILVA, Clovis Artur; BONFA, EloisaMethods. One hundred and twenty patients (RA, n = 41; AS, n = 57; PsA, n = 22) on anti-TNF agents (monoclonal, n = 94; soluble receptor, n = 26) were compared with 116 inflammatory arthritis patients under DMARDs and 117 healthy controls. Seroprotection, seroconversion (SC), geometric mean titre, factor increase in geometric mean titre and adverse events were evaluated 21 days after vaccination. Results. After immunization, SC rates (58.2% vs 74.3%, P = 0.017) were significantly lower in SpA patients receiving anti-TNF therapy, whereas no difference was observed in RA patients receiving this therapy compared with healthy controls (P = 0.067). SpA patients receiving mAbs (infliximab/adalimumab) had a significantly lower SC rate compared with healthy controls (51.6% vs 74.3%, P = 0.002) or those on DMARDs (51.6% vs 74.7%, P = 0.005), whereas no difference was observed for patients on etanercept (86.7% vs 74.3%, P = 0.091). Further analysis of non-seroconverting and seroconverting SpA patients revealed that the former group had a higher mean age (P = 0.003), a higher frequency of anti-TNF (P = 0.031) and mAbs (P = 0.001) and a lower frequency of MTX (P = 0.028). In multivariate logistic regression, only older age (P = 0.015) and mAb treatment (P = 0.023) remained significant factors for non-SC in SpA patients. Conclusion. This study revealed a distinct disease pattern of immune response to the pandemic influenza vaccine in inflammatory arthritis patients receiving anti-TNF agents, illustrated by a reduced immunogenicity solely in SpA patients using mAbs.
