    Diagnosis and treatment of interstitial lung disease related to systemic autoimmune myopathies: a narrative review
    (2023) SOUZA, F. H. C. de; ARAUJO, D. B. de; HOFF, L. S.; BALDI, B. G.; FARIA, M. S. M. S.; ROCHA JUNIOR, L. F. da; SILVA, L. R. S. Da; PINTO, Behrens; BEZERRA, M. C.; MIOSSI, R.; CORDEIRO, R. A.; SHINJO, S. K.
    Systemic autoimmune myopathies (SAMs) are rare diseases that lead to muscle inflammation and may be associated with a variety of systemic manifestations. Although there is great heterogeneity in the spectrum of extra-muscular involvement in SAMs, interstitial lung disease (ILD) is the most frequent lung manifestation. SAM-related ILD (SAM-ILD) presents significant variations according to geographic location and temporal trends and is associated with increased morbidity and mortality. Several myositis autoantibodies have been discovered over the last decades, including antibodies targeting aminoacyl-tRNA synthetase enzymes, which are associated with a variable risk of developing ILD and a myriad of other clinical features. In this review, the most relevant topics regarding clinical manifestations, risk factors, diagnostic tests, autoantibodies, treatment, and prognosis of SAM-ILD are highlighted. We searched PubMed for relevant articles published in English, Portuguese, or Spanish from January 2002 to September 2022. The most common SAM-ILD patterns are nonspecific interstitial pneumonia and organizing pneumonia. The combination of clinical, functional, laboratory, and tomographic features is usually sufficient for diagnostic confirmation, without the need for additional invasive methods. Glucocorticoids remain the first-line treatment for SAM-ILD, although other traditional immunosuppressants, such as azathioprine, mycophenolate, and cyclophosphamide have demonstrated some efficacy and, therefore, have an important role as steroid-sparing agents.

    Immunogenicity and safety of primary fractional-dose yellow fever vaccine in autoimmune rheumatic diseases
    (2021) TONACIO, Adriana Coracini; PEDROSA, Tatiana do Nascimento; BORBA, Eduardo Ferreira; AIKAWA, Nadia Emi; PASOTO, Sandra Gofinet; FERREIRA FILHO, Julio Cesar Rente; BARROS, Marilia Mantovani Sampaio; LEON, Elaine Pires; LOMBARDI, Suzete Cleusa Ferreira Spina; MENDRONE JUNIOR, Alfredo; AZEVEDO, Adriana de Souza; SCHWARCZ, Waleska Dias; FULLER, Ricardo; YUKI, Emily Figueiredo Neves; LOPES, Michelle Remiao Ugolini; PEREIRA, Rosa Maria Rodrigues; BARROS, Percival Degrava Sampaio; ANDRADE, Danieli Castro Oliveira de; MEDEIROS-RIBEIRO, Ana Cristina de; MORAES, Julio Cesar Bertacini de; SHINJO, Samuel Katsuyuki; MIOSSI, Renata; DUARTE, Alberto Jose da Silva; LOPES, Marta Heloisa; KALLAS, Esper Georges; SILVA, Clovis Artur Almeida da; BONFA, Eloisa
    Background Brazil faced a yellow fever(YF) outbreak in 2016-2018 and vaccination was considered for autoimmune rheumatic disease patients(ARD) with low immunosuppression due to YF high mortality. Objective This study aimed to evaluate, prospectively for the first time, the short-term immunogenicity of the fractional YF vaccine(YFV) immunization in ARD patients with low immunossupression. Methods and Results A total of 318 participants(159 ARD and 159 age- and sex-matched healthy controls) were vaccinated with the fractional-dose(one fifth) of 17DD-YFV. All subjects were evaluated at entry(D0), D5, D10, and D30 post-vaccination for clinical/laboratory and disease activity parameters for ARD patients. Post-vaccination seroconversion rate(83.7%vs.96.6%, p = 0.0006) and geometric mean titers(GMT) of neutralizing antibodies[1143.7 (95%CI 1012.3-1292.2) vs.731 (95%CI 593.6-900.2), p< 0.001] were significantly lower in ARD compared to controls. A lower positivity rate of viremia was also identified for ARD patients compared to controls at D5 (53%vs.70%, p = 0.005) and the levels persisted in D10 for patients and reduced for controls(51%vs.19%, p = 0.0001). The viremia was the only variable associated with seroconvertion. No serious adverse events were reported. ARD disease activity parameters remained stable at D30(p>0.05). Conclusion Fractional-dose 17DD-YF vaccine in ARD patients resulted in a high rate of seroconversion rate(> 80%) but lower than controls, with a longer but less intense viremia. This vaccine was immunogenic, safe and did not induce flares in ARD under low immunosuppression and may be indicated in YF outbreak situations and for patients who live or travel to endemic areas.

    Gathering patients and rheumatologists' perceptions to improve outcomes in idiopathic inflammatory myopathies
    (2022) BERTOGLIO, Isabela M.; ABRAHAO, Glaucia F.; SOUZA, Fernando H. C. de; MIOSSI, Renata; MORAES, Paloma C. de; SHINJO, Samuel K.; BONFA, Eloisa; LOPES, Michelle R. Ugolini
    Objective: Therapeutic targets in Idiopathic Inflammatory Myopathies (IIM) are based on the opinions of physicians/specialists, which may not reflect the main concerns of patients. The authors, therefore, assessed the outcome concerns of patients with IIM and compared them with the concerns of rheumatologists in order to develop an IIM outcome standard set. Methods: Ninety-three IIM patients, 51 rheumatologists, and one physiotherapist were invited to participate. An open questionnaire was initially applied. The top 10 answers were selected and applied in a multiple-choice questionnaire, inquiring about the top 3 major concerns. Answers were compared, and the agreement rate was calculated. Concerns were gathered in an IIM outcome standard set with validated measures. Results: The top three outcome concerns raised by patients were medication side effects/muscle weakness/prevention functionality loss. The top three concerns among rheumatologists were to prevent loss of functionality/to ensure the quality of life/to achieve disease remission. Other's outcomes concerns only pointed out by patients were muscle pain/diffuse pain/skin lesions/fatigue. The agreement rate between both groups was 41%. Assessment of these parameters guided the development of an IIM standard set which included Myositis Disease Activity Assessment Visual Analogue Scale/Manual Muscle Testing/fatigue and pain Global Visual Analogue Scale/Health Assessment Questionnaire/level of physical activity. Conclusion: The authors propose a novel standard set to be pursued in IIM routine follow-up, which includes not only the main patients/rheumatologist outcome concerns but also additional important outcomes only indicated by patients. Future studies are necessary to confirm if this comprehensive approach will result in improved adherence and ultimately in better assistance.

    Necrotising myopathy associated with anti-signal recognition particle (anti-SRP) antibody
    (2017) SOUZA, F. H. C. de; MIOSSI, R.; SHINJO, S. K.
    Objective Prompted by the few studies available in the literature, we analysed patients with necrotising myopathy associated with anti-signal recognition particle (anti-SRP). Methods We conducted a retrospective, single-centre cohort study involving 14 patients with anti-SRP antibody followed between 2001 and 2016. Results Patients had a mean age at disease onset of 40.7 years and were predominantly female and of white ethnicity. At disease onset, all patients had limb muscle weakness with median serum of creatine phosphokinase level of 8080U/L, 64.3% had constitutional symptoms, 50% dysphagia, 42.9% myalgia, 21.4% and 14.3% pulmonary and articular involvement, respectively. There were no cases of cutaneous, neurological or cardiac involvements. Notably, 21.4% of patients had previous exposure to statins. Moreover, with the exception of one patient, all received methylprednisolone pulse therapy and/or human intravenous immunoglobulin (IVIg), as well as prednisone and different immunosuppressive drugs or rituximab. Relapse occurred in 64.3% of the cases. However, most patients had significant recovery of muscle strength, with half no longer using glucocorticoids and the remainder on a weaning regimen with low dose prednisone. Conclusion Unlike the cases described in the literature, there was a high frequency of extra-muscular symptoms in the patients studied. Moreover, one fifth of patients had previous exposure to statin use. There was a high relapse rates, but with good clinical and laboratory recovery, especially with pulse therapy regimen of methylprednisolone and/or IVIg.

    Could C-reactive protein and erythrocyte sedimentation rate support monitoring of dermatomyositis and polymyositis activity?
    (2017) MIOSSI, Renata; SOUZA, Fernando Henrique Carlos de; SHINJO, Samuel Katsuyuki
    OBJECTIVES: To evaluate serum levels of C-reactive protein and erythrocyte sedimentation rates in patients with untreated newly diagnosed dermatomyositis or polymyositis and their correlation with clinical and laboratory parameters. METHODS: A cross-sectional study including 48 consecutive patients with untreated newly diagnosed dermatomyositis and polymyositis reviewed between 2002 and 2015 was conducted. Fifty healthy subjects were enrolled as controls. RESULTS: Patients with dermatomyositis and polymyositis had higher levels of C-reactive protein and erythrocyte sedimentation rate than healthy controls, but these values were not associated with clinical or laboratory parameters of disease activity either for dermatomyositis or for polymyositis. Additionally, erythrocyte sedimentation rate values correlated with pulmonary involvement as evidenced through computer tomography imaging (OR 1.15; 95%CI 1.01-1.31) only in patients with polymyositis. CONCLUSIONS: Although elevated, C-reactive protein and erythrocyte sedimentation rate are not sensitive parameters for measuring clinical and laboratory activity of dermatomyositis nor for polymiositis. However, erythrocyte sedimentation rate may be a valid parameter for screening pulmonary involvement, particularly in patients with polymyositis.

    Characterising 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.
