    The aerobic capacity in patients with antisynthetase syndrome and dermatomyositis
    (2019) SANTOS, Alexandre Moura dos; MISSE, Rafael Giovani; BORGES, Isabela Bruna Pires; SHINJO, Samuel Katsuyuki
    Background This study was aimed at evaluating the aerobic capacity of patients with antisynthetase syndrome (ASS) and dermatomyositis (DM) and analyzing possible relationships between aerobic capacity and disease status, cardiovascular diseases and their risk factors. Methods The study was a cross-sectional, single-center study that assessed the aerobic capacity of 22 women (13 with DM and 9 with ASS) who were matched by age and body mass index to 17 healthy women (control group). The aerobic capacity (oxygen uptake [VO2 peak], anaerobic threshold, respiratory compensation point and time-to-exhaustion) was evaluated using the cardiopulmonary treadmill test. Disease status was assessed using International Myositis Assessment & Clinical Studies Group (IMACS) set scores. Results The patients had low IMACS parameters that showed low or absent disease activity. The distribution of cardiovascular diseases and their risk factors was similar between the patients and the control group (P > 0.05) at the time of the analysis. The patients with DM and the control group had similar aerobic capacity. However, the patients with ASS exhibited significantly reduced aerobic capacity (relative VO2 peak, anaerobic threshold, respiratory compensation point and time to exhaustion) when compared to the control group. In addition, patients with ASS had a lower anaerobic threshold compared to the DM group. There were no significant relationships between the aerobic capacity and disease status, cardiovascular diseases and their risk factors. Conclusion In contrast to DM patients and healthy individuals, patients with stable ASS have significantly impaired aerobic capacity, which is unlikely to be totally explained by traditional cardiovascular diseases, their risk factors and disease status. Further studies are needed to corroborate our data and to clarify the cause of this reduced aerobic capacity in ASS.

    High prevalence of fatigue in patients with Takayasu arteritis: a case-control study in a Brazilian centre
    (2022) SANTOS, Alexandre Moura dos; MISSE, Rafael Giovani; BORGES, Isabela Bruna Pires; SILVA, Sarah Luiza Gomes da; KIM, Ana Woo Sook; PEREIRA, Rosa Maria R.; SHINJO, Samuel Katsuyuki
    Objectives. Several studies have shown not only a high prevalence of fatigue but also a reduction in health-related quality of life (HRQoL) in patients with rheumatic diseases. Owing to insufficient research in this area, we aimed to assess the prevalence of fatigue and its contribution to impairment of HRQoL in patients with Takayasu arteritis (TAK). Methods. This single-centre case-control study included 53 TAK patients who were matched by age, BMI and sex with 100 healthy individuals. Aside from the patients' general data, the following information was collected: disease activity, level of activities of daily living (HAQ), physical activity levels and chronic fatigue. Results. The TAK patients and healthy individuals were comparable in terms of current age, BMI and sex distribution. The median disease duration of TAK was 13.0 (7.0-20.0) years, and 11 (20.8%) patients had active disease. Compared with healthy individuals, patients with TAK had a higher prevalence of fatigue and lower HAQ score, physical activity level and intensity, and physical and psychosocial domains of the modified fatigue impact scale (P < 0.01). Moreover, TAK patients had increased fatigue rates compared with the healthy individuals (fatigue severity scale: odds ratio = 2.6; 95% CI = 1.2, 5.4; modified fatigue impact scale: odds ratio = 2.6; 95% CI = 1.2, 5.5). Fatigue was positively correlated with worsening HAQ, CRP levels, daily prednisone dose and disease activity, and negatively correlated with disease duration. Conclusion. TAK patients have a higher prevalence of fatigue, which affects different aspects of the disease, including physical function. Thus, fatigue-focused treatments should also be considered in clinical practice.

    Feasibility, safety and efficacy of exercise training in immune-mediated necrotising myopathies: a quasi-experimental prospective study
    (2019) SOUZA, J. M. de; OLIVEIRA, D. S. de; PERIN, L. A.; MISSE, R. G.; SANTOS, A. M. dos; GUALANO, B.; PINTO, A. L. de Sa; ROSCHEL, H.; LIMA, F. R.; SHINJO, S. K.
    Objective To evaluate the feasibility, safety and efficacy of exercise training in patients with immune-mediated necrotising myopathies (IMNM). Methods Eight consecutive sedentary patients with IMNM (5 anti-signal recognition particle and 3 anti-hydroxy-methyl-glutaryl coenzyme A reductase) were engaged in this study. Disease status was based on International Myositis Assessment and Clinical Studies Group (IMACS) core set measures. Physical performance was evaluated by cardiopulmonary exercise test, repetition maximum (RM) protocol, handgrip dynamometry, sit-to-stand (STS) and timed up-and-go (TUG) tests. All these parameters were measured at baseline and after a 12-week, twice-a-week, supervised exercise training comprising aerobic and strength exercises. Results Patients (aged 61 years on average) were very disabled at the beginning of the disease (mean duration of 17.7 months), but after being aggressively treated with a treat-to-target approach, they presented only mild symptoms that were well-controlled with oral immunosuppression and low disease status scores by the time of the exercise intervention. No disease relapsing, worsening of the IMACS set scores or adverse events were observed throughout the training period. Patients also increased aerobic capacity (e.g. time to achieve anaerobic threshold and time to achieve exhaustion), muscle strength (e.g. 1RM bench press) and function (e.g. STS test). Conclusion Supervised exercise training did not impair disease status and seemed to be feasible, safe and effective in patients with IMNM. Moreover, exercise training increased aerobic capacity, muscle strength and function, suggesting that this could be a novel potential coadjuvant therapy in IMNM.

    Physical exercise for the management of systemic autoimmune myopathies: recent findings, and future perspectives
    (2021) SANTOS, Alexandre Moura dos; MISSE, Rafael Giovani; BORGES, Isabela Bruna Pires; PERANDINI, Luiz Augusto Buoro; SHINJO, Samuel Katsuyuki
    Purpose of review The aim of this review is to present the main pieces of evidence, recent literature and to present future perspectives on the use of exercise/physical training in the treatment and improvement of the quality of life of patients with systemic autoimmune myopathies. Recent findings In the last decades, knowledge about the relevance of physical exercise training in preventing and treating chronic diseases and improving quality of life has grown. Following the global trend exemplified by the expression 'exercise is medicine', the importance of exercise/physical training has also grown in myopathies. However, the science of exercise has a lot to collaborate on and improve patients' quality of life with myopathies by appropriating new technological tools, including accessible and low-cost devices and smartphone apps. Physical exercise, as already consolidated in the literature, is an effective, well tolerated, and low-cost strategy for patients with myopathies. The use of wearable devices, smartphone apps, and online training prescriptions must accompany the global scenario, bringing new research fields and expanding the options for access to training for the individualized basis, and prescribed by qualified professionals.

    Systemic autoimmune myopathies: a prospective phase 4 controlled trial of an inactivated virus vaccine against SARS-CoV-2
    (2022) SHINJO, Samuel K.; SOUZA, Fernando H. C. de; BORGES, Isabela B. P.; SANTOS, Alexandre M. Dos; MIOSSI, Renata; MISSE, Rafael G.; MEDEIROS-RIBEIRO, Ana C.; SAAD, Carla G. S.; YUKI, Emily F. N.; PASOTO, Sandra G.; KUPA, Leonard V. K.; CENEVIVA, Carina; SERAPHIM, Julia C.; PEDROSA, Tatiana N.; VENDRAMINI, Margarete B. G.; SILVA, Clovis A.; AIKAWA, Nadia E.; BONFA, Eloisa
    Objectives. To evaluate immunogenicity and safety of an inactivated SARS-CoV-2 vaccine in systemic autoimmune myopathies (SAMs) and the possible influence of baseline disease parameters, comorbidities and therapy on immune response. Methods. This prospective controlled study included 53 patients with SAMs and 106 non-immunocompromised control group (CTRL). All participants received two doses of the Sinovac-CoronaVac vaccine (28-day interval). Immunogenicity was assessed by anti-SARS-CoV-2 S1/S2 IgG seroconversion (SC), anti-S1/S2 IgG geometric mean titre (GMT), factor increase GMT (FI-GMT), neutralizing antibodies (NAb) positivity, and median neutralizing activity after each vaccine dose (D0 and D28) and six weeks after the second dose (D69). Participants with pre-vaccination positive IgG serology and/or NAb and those with RT-PCR confirmed COVID-19 during the protocol were excluded from immunogenicity analysis. Results. Patients and CTRL had comparable sex (P>0.99) and age (P=0.90). Immunogenicity of 37 patients and 79 CTRL-naive participants revealed at D69, a moderate but significantly lower SC (64.9% vs 91.1%, P<0.001), GMT [7.9 (95%CI 4.7-13.2) vs 24.7 (95%CI 30.0-30.5) UA/ml, P<0.001] and frequency of NAb (51.4% vs 77.2%, P<0.001) in SAMs compared with CTRL. Median neutralizing activity was comparable in both groups [57.2% (interquartile range (IQR) 43.4-83.4) vs 63.0% (IQR 40.3-80.7), P=0.808]. Immunosuppressives were less frequently used among NAb+ patients vs NAb- patients (73.7% vs 100%, P=0.046). Type of SAMs, disease status, other drugs or comorbidities did not influence immunogenicity. Vaccine-related adverse events were mild with similar frequencies in patients and CTRL (P>0.05). Conclusion. Sinovac-CoronaVac is safe and has a moderate short-term immunogenicity in SAMs, but reduced compared with CTRL. We further identified that immunosuppression is associated with diminished NAb positivity.

    Is there a reliable association between patient-reported limb claudication and vascular imaging methods in Takayasu arteritis?
    (2020) ARAUJO, C. S. R.; SANTOS, A. M. dos; PALLO, P. A. Olivo; PEREIRA, R. M. R.; SHINJO, S. K.
    Vessel imaging in Takayasu arteritis (TAK) is often performed in clinical practice following laboratory test abnormalities or clinical symptoms, such as limb claudication. Conversely, the association between limb claudication and vessel imaging manifestations has not been assessed. This observational, cross-sectional study analyzed 139 adult TAK patients from 2000 to 2018. Their arterial vessel imaging information (especially significant stenosis and occlusion data) was registered and crosschecked with clinical and laboratory data. When vessel imaging was performed, the median age and disease duration of the patients were 38 (27.3-47.0) and 5.0 (1.0-12.0) years, respectively. There was no association between arterial abnormalities and demographic data, constitutional symptoms or laboratory parameters. Limb claudication was reported in 42 patients (30.2%): 17.3% reported it in the upper left limb (ULL), 12.2% reported it in the upper right limb (URL), 12.9% reported it in the lower left limb (LLL), and 12.2% reported it in the lower right limb (LRL). When crossmatched with imaging, both ULL and URL were associated with left vertebral artery stenosis/occlusion, and URL was associated with right iliac artery stenosis/occlusion, but no other association was found. In contrast, both LLL and LRL claudication were associated with infrarenal aortic, left iliac and right iliac artery stenosis/occlusion (p<0.05). Moreover, the ULL and URL claudication symptoms were significantly associated with each other (p<0.001). Upper limb claudication was associated only with left vertebral artery stenosis/occlusion, whereas the subclavian arteries were not, suggesting that the symptom might not be fully explained by limb ischemia. In contrast, lower limb claudication was associated especially with infrarenal aortic and/or iliac arteries stenosis/occlusion.

    Particularidades dos Pacientes com Arterite de Takayasu em Idade Mais Avan?ada: Estudo Coorte, Retrospectivo e Transversal
    (2023) OLIVEIRA, Joao Calvino Soares de; SANTOS, Alexandre Moura dos; AGUIAR, Mariana Freitas de; GONCALVES JUNIOR, Jucier; SOUZA, Alexandre Wagner Silva de; PEREIRA, Rosa Maria R.; SHINJO, Samuel Katsuyuki
    Background: Few studies have assessed elderly patients with Takayasu's arteritis (TAK). Objectives: To evaluate the progression of TAK in different age groups and its possible effects on drug treatment and disease activity.Methods: This cross-sectional and retrospective cohort study included 66 TAK patients. Patients were interviewed and data of the 12 preceding months were collected from electronic medical records. The patients were divided into four quartiles according to current age and compared for clinical and laboratory data, treatment, comorbidities, disease status, and functional status. Statistical significance was set at p<0.05.Results: The groups were Q1(22-36 years, n=16), Q2(37-42 years, n=18), Q3(43-49 years, n=17), and Q4(51-66 years, n=15). The frequency of patients with disease activity, fatigue, comorbidities and vascular impairments, and the TAK disease extent index were also comparable between the groups. With age, disease duration was longer (p=0.001), fewer patients used prednisone (Q1:43.8%, Q2:33.3%, Q3:11.8%, and Q4:6.7%; p=0.049) and immunosuppressive drugs [Q1:100.0%, Q2:66.7%, Q3:58.8%, and Q4:46.7%; Q1 versus Q3 (p=0.043), and Q1 versus Q4 (p=0.005) in post-hoc analysess, and patients had greater functional status impairment (Q2 versus Q3, p=0.003). In addition, the levels of disease damage, new TAK symptoms, and complications in the preceding 12 months were not different between the groups.Conclusions: Older patients with TAK require minimal drug treatment, and have greater impairment of functional status, which may be attributed to factors.

    Increased modifiable cardiovascular risk factors in patients with Takayasu arteritis: a multicenter cross-sectional study
    (2021) SANTOS, Alexandre Moura dos; MISSE, Rafael Giovani; BORGES, Isabela Bruna Pires; GUALANO, Bruno; SOUZA, Alexandre Wagner Silva de; TAKAYAMA, Liliam; PEREIRA, Rosa Maria R.; SHINJO, Samuel Katsuyuki
    Background: Modifiable cardiovascular risk factors (MCRFs), such as those related to aerobic capacity, muscle strength, physical activity, and body composition, have been poorly studied in Takayasu arteritis (TAK). Therefore, the aim of the study was to investigate MCRFs and their relationships with disease status and comorbidities among patients with TAK. Methods: A multicenter cross-sectional study was conducted between 2019 and 2020, in which 20 adult women with TAK were compared with 16 healthy controls matched by gender, age, and body mass index. The following parameters were analyzed: aerobic capacity by cardiopulmonary test; muscle function by timed-stands test, timed up-and-go test, and handgrip test; muscle strength by one-repetition maximum test and handgrip test; body composition by densitometry; physical activity and metabolic equivalent by IPAQ, quality of life by HAQ and SF-36; disease activity by ITAS2010 and NIH score; and presence of comorbidities. Results: Patients with TAK had a mean age of 41.5 (38.0-46.3) years, disease duration of 16.0 (9.5-20.0) years, and a mean BMI of 27.7 +/- 4.5 kg/m(2). Three out of the 20 patients with TAK had active disease. Regarding comorbidities, 16 patients had systemic arterial hypertension, 11 had dyslipidemia, and two had type 2 diabetes mellitus, while the control group had no comorbidities. TAK had a significant reduction in aerobic capacity (absolute and relative VO2 peak), muscle strength in the lower limbs, increased visceral adipose tissue, waist-to-hip ratio, reduced walking capacity, decreased weekly metabolic equivalent, and quality of life (P< 0.05) as compared to controls. However, there were no correlations between these MCRFs parameters and disease activity. Conclusions: TAK show impairment in MCRFs; therefore, strategies able to improve MCRF should be considered in this disease.
