- 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.

Until this moment, there have been described in literature only seven cases of inhibitors of tumor necrosis factor induced-myositis. In this paper, we report the case of the patient with 39 years-old with eight years of arthritis rheumatoid and that due to refractory to various immunosuppressive drugs, the adalimumab was introduced, and evolved to dermatomyositis status.- Reduced ovarian reserve in patients with adult polymyositis(2015) SOUZA, Fernando Henrique Carlos de; SILVA, Clovis Artur da; YAMAKAMI, Lucas Yugo Shiguehara; VIANA, Vilma dos Santos Trindade; BONFA, Eloisa; SHINJO, Samuel KatsuyukiPolymyositis (PM) affects female gender during reproductive age; however, there is no study assessing ovarian reserve in these patients to evaluate ovarian reserve markers in PM. Eight female patients with PM (Bohan and Peter criteria, 1975) with aged 18-40 years, followed at our tertiary centre from March 2011 to May 2014, were invited to participate. They were age-matched with 16 healthy individuals (control group). All were evaluated at early follicular phase of menstrual cycle. Follicle stimulating hormone (FSH), estradiol, inhibin B, anti-Mullerian hormone (AMH) serum levels (ELISA) and sonographic antral follicle count (AFC) were determined. PM patients and controls had comparable mean age (31.4 +/- 6.5 vs. 30.7 +/- 6.2 years, P = 0.946), ethnicity and socioeconomic class (P > 0.05). PM mean age of onset was 27.3 +/- 6.5 years and disease duration of 6.5 +/- 4.1 years. Menstrual cycles were alike in both groups with a similar frequency of age at menarche, gynaecological age, duration and length of menstrual cycle (P > 0.05). The median serum level of AMH was significantly lower in PM compared to controls [0.7(0.3-3.4) vs. 3.1(1.4-4.0), P = 0.021]. AMH levels a parts per thousand currency sign1 ng/mL (50 vs. 6.3 %, P = 0.024) and very low AFC (37.5 vs. 6.3 %, P = 0.037) were significantly in PM patients versus controls. The other hormones (FSH, inhibin B and estradiol levels) were similar between both groups (P > 0.05). The present study was the first to identify subclinical ovarian dysfunction in PM patients during reproductive ages. Further study is necessary to assess the possible role of PM-related factors that may influence the ovarian function of these patients.
- Myositis-specific and myositis-associated autoantibody profiles and their clinical associations in a large series of patients with polymyositis and dermatomyositis(2013) CRUELLAS, Marcela Gran Pina; VIANA, Vilma dos Santos Trindade; LEVY-NETO, Mauricio; SOUZA, Fernando Henrique Carlos de; SHINJO, Samuel KatsuyukiOBJECTIVE: To analyze the prevalence of myositis-specific and myositis-associated autoantibodies and their clinical correlations in a large series of patients with dermatomyositis/polymyositis. METHOD: This cross-sectional study enrolled 127 dermatomyositis cases and 95 polymyositis cases. The disease-related autoantibody profiles were determined using a commercially available blood testing kit. RESULTS: The prevalence of myositis-specific autoantibodies in all 222 patients was 34.4%, whereas myositis-associated autoantibodies were found in 41.4% of the patients. The most frequently found autoantibody was anti-Ro-52 (36.9%), followed by anti-Jo-1 (18.9%), anti-Mi-2 (8.1%), anti-Ku (4.1%), anti-SRP (3.2%), anti-PL-7 (3.2%), anti-PL-12 (2.7%), anti-PM/Scl75 (2.7%), and anti-PM/Scl100 (2.7%). The distributions of these autoantibodies were comparable between polymyositis and dermatomyositis, except for a higher prevalence of anti-Jo-1 in polymyositis. Anti-Mi-2 was more prevalent in dermatomyositis. Notably, in the multivariate analysis, anti-Mi-2 and anti-Ro-52 were associated with photosensitivity and pulmonary disorders, respectively, in dermatomyositis. Anti-Jo-1 was significantly correlated with pulmonary disorders in polymyositis. Moreover, anti-Ro-52 was associated with anti-Jo-1 in both diseases. No significant correlation was observed between the remaining autoantibodies and the clinical and/or laboratory findings. CONCLUSIONS: Our data are consistent with those from other published studies involving other populations, although certain findings warrant consideration. Anti-Ro-52 and anti-Jo-1 were strongly associated with one another. Anti-Ro-52 was correlated with pulmonary disorders in dermatomyositis, whereas anti-Jo-1 was correlated with pulmonary alterations in polymyositis.
conferenceObject Reduction of Ovarian Reserve in Adult Patients with Dermatomyositis.(2014) SOUZA, Fernando Henrique Carlos de; SHINJO, Samuel Katsuyuki; YAMAKAMI, Lucas Yugo Shiguehara; VIANA, Vilma dos Santos Trindade; BARACAT, Edmund Chada; BONFA, Eloisa; SILVA, Clovis Artur Almeidaarticle 17 Citação(ões) na Scopus Reduction of ovarian reserve in adult patients with dermatomyositis(2015) SOUZA, F. H. C. de; SHINJO, S. K.; YAMAKAMI, L. Y. S.; VIANA, V. S. T.; BARACAT, E. C.; BONFA, E.; SILVA, C. A.Objective To assess ovarian reserve markers and anti-corpus luteum (anti-CoL) antibodies in dermatomyositis (DM) patients. Methods Forty female DM patients were invited to participate. Exclusion criteria included hormonal contraceptive use within the last six months, neoplasia associations, overlapped systemic autoimmune diseases, current pregnancy, gynaecological surgery and individual choice not to participate. The final experimental group for this cross-sectional study included 16 DM patients and 23 healthy controls, each of whom was evaluated during the early follicular phase of the menstrual cycle. Values for IgG anti-CoL (via immunoblotting), follicle stimulating hormone (FSH), estradiol, inhibin B, anti-Mullerian hormone (AMH) serum levels (via ELISA) and sonographic antral follicle count (AFC) were determined. Results DM patients and controls were of comparable mean age (p>0.05). The mean age of DM onset was 29.1 +/- 4.7 years, with disease duration of 5.6 +/- 3.2 years. Menstrual cycle characteristics, comorbidity and lifestyle were similar amongst patients in both groups (p>0.05). AMH values of <= lng/mL (p=0.027) and AFC values (p=0.017) were significantly reduced in DM patients relative to the control group, whereas serum estradiol levels (p<0.001) were higher in DM patients compared to controls. In contrast, serum FSH and inhibin B levels, ovarian volumes, and anti-CoL antibody frequency were similar in both groups. Differences in AFC and estradiol were determined to be significant following Bonferroni correction for multiple testing. Conclusion We identified a diminished ovarian reserve in DM patients of reproductive age. Further studies are necessary to assess the idiopathic inflammatory myopathy-related factors involved in the ovarian impairment of this patient population.bookPart Miopatias autoimunes sistêmicas(2021) SOUZA, Fernando Henrique Carlos de; MIOSSI, Renata; SHINJO, Samuel Katsuyuki- Anti-synthetase syndrome: anti-PL-7, anti-PL-12 and anti-EJ(2013) SOUZA, Fernando Henrique Carlos de; CRUELLAS, Marcela Gran Pina; LEVY-NETO, Mauricio; SHINJO, Samuel KatsuyukiObjectives: Due to the scarcity of studies in the literature, we conducted an analysis of a series of patients with the anti-PL-7, PL-12 and EJ types of antisynthetase syndrome (ASS). Methods: We conducted a retrospective cohort study of 20 patients with ASS (8 with anti-PL-7, 6 with PL-12, 6 with EJ) monitored in our department between 1982 and 2012. Results: The mean patient age at disease onset was 38.5 +/- 12.9 years, and the disease duration was 4.5 +/- 6.4 years. Of all the patients, 70% were white and 85% were female. Constitutional symptoms occurred in 90% of cases. All patients presented objective muscle weakness in the limbs; in addition, 30% were bedridden and 65% demonstrated high dysphagia at diagnosis. Joint and pulmonary involvement and Raynaud's phenomenon occurred in 50%, 40% and 65% of cases, respectively, with more than half of the patients presenting incipient pneumopathy, ground-glass opacity and/or pulmonary fibrosis. There were no cases of neurological and/or cardiac involvement. All patients received prednisone or other immunosuppressants depending on tolerance, side effects and/or disease refractoriness. Importantly, patients with the anti-EJ type of ASS demonstrated higher rates of recurrence. Two patients died during follow-up, and 1 patient had breast cancer at the time of diagnosis. Conclusions: ASS (anti-PL-7, PL-12 and EJ) was found to predominantly affect white women. Although the autoantibodies described in the present study are more related to pulmonary than joint involvement, our patients showed a significant percentage of both types of involvement and a high percentage of myopathy. We also observed a low mortality rate.
