R.bookPart Artrites Infecciosas(2018) PRADO, Leandro Lara do; LEVY-NETO, MaurícioconferenceObject High Prevalence Of Metabolic Syndrome In Takayasu Arteritis: An Increased Cardiovascular Risk and Lower Adiponectin Serum Levels(2013) SILVA, Thiago; LEVY-NETO, Mauricio; PEREIRA, Rosa M. R.; BONFA, Eloisa- Relapsing polychondritis: prevalence of cardiovascular diseases and its risk factors, and general disease features according to gender(2017) PALLO, Pablo Arturo Olivo; LEVY-NETO, Mauricio; PEREIRA, Rosa Maria Rodrigues; SHINJO, Samuel KatsuyukiThe comorbidities in relapsing polychondritis (RP) have been scarcely described in the literature. Moreover, apart from a few RP epidemiological studies, no studies specifically addressing RP distribution according to gender are available. Therefore, the objetives of the present study were: (a) to analyse the prevalence of cardiovascular diseases and its risk factors in a series of patients with RP; (b) to determine the influence of gender on RP. A cross-sectional tertiary single center study evaluating 30 RP cases from 1990 to 2016 was carried out. To compare comorbidities, 60 healthy individuals matched for age-, gender-, ethnicity-and body mass index were recruted. The mean age of RP patientes was 49.0 +/- 12.4 years, the median disease duration 6.0 years, and 70% were women. A higher frequency of arterial hypertension (53.3% vs. 23.3%; p = 0.008) and diabetes mellitus (16.7% vs. 3.3%; p = 0.039) was found in the RP group, compared to the control group. As an additional analysis, patients were compared according to gender distribution (9 men vs. 21 women). The clinical disease onset features were comparable in both genders. However, over the follow-up period, male patients had a greater prevalence of hearing loss, vestibular disorder and uveitis events, and also received more cyclophosphamide therapy (p < 0.05). There was a high prevalence of arterial hypertension and diabetes mellitus, and the male patients seemed to have worse prognosis than the female patients in the follow up.

- Immunogenicity and safety of the 2009 non-adjuvanted influenza A/H1N1 vaccine in a large cohort of autoimmune rheumatic diseases(2011) SAAD, Carla G. S.; BORBA, Eduardo F.; AIKAWA, Nadia E.; SILVA, Clovis A.; PEREIRA, Rosa M. R.; CALICH, Ana Luisa; MORAES, Julio C. B.; RIBEIRO, Ana C. M.; VIANA, Vilma S. T.; PASOTO, Sandra G.; CARVALHO, Jozelio F.; FRANCA, Ivan L. A.; GUEDES, Lissiane K. N.; SHINJO, Samuel K.; SAMPAIO-BARROS, Percival D.; CALEIRO, Maria T.; GONCALVES, Celio R.; FULLER, Ricardo; LEVY-NETO, Mauricio; TIMENETSKY, Maria do Carmo S.; PRECIOSO, Alexander R.; BONFA, EloisaBackground Despite the WHO recommendation that the 2010-2011 trivalent seasonal flu vaccine must contain A/California/7/2009/H1N1-like virus there is no consistent data regarding its immunogenicity and safety in a large autoimmune rheumatic disease (ARD) population. Methods 1668 ARD patients (systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), ankylosing spondylitis (AS), systemic sclerosis, psoriatic arthritis (PsA), Behcet's disease (BD), mixed connective tissue disease, primary antiphospholipid syndrome (PAPS), dermatomyositis (DM), primary Sjogren's syndrome, Takayasu's arteritis, polymyositis and Granulomatosis with polyangiitis (Wegener's) (GPA)) and 234 healthy controls were vaccinated with a non-adjuvanted influenza A/California/7/2009(H1N1) virus-like strain flu. Subjects were evaluated before vaccination and 21 days post-vaccination. The percentage of seroprotection, seroconversion and the factor increase in geometric mean titre (GMT) were calculated. Results After immunisation, seroprotection rates (68.5% vs 82.9% p < 0.0001), seroconversion rates (63.4% vs 76.9%, p < 0.001) and the factor increase in GMT (8.9 vs 13.2 p < 0.0001) were significantly lower in ARD than controls. Analysis of specific diseases revealed that seroprotection significantly reduced in SLE (p < 0.0001), RA (p < 0.0001), PsA (p=0.0006), AS (p=0.04), BD (p=0.04) and DM (p=0.04) patients than controls. The seroconversion rates in SLE (p < 0.0001), RA (p < 0.0001) and PsA (p=0.0006) patients and the increase in GMTs in SLE (p < 0.0001), RA (p < 0.0001) and PsA (p < 0.0001) patients were also reduced compared with controls. Moderate and severe side effects were not reported. Conclusions The novel recognition of a diverse vaccine immunogenicity profile in distinct ARDs supports the notion that a booster dose may be recommended for diseases with suboptimal immune responses. This large study also settles the issue of vaccine safety. (ClinicalTrials.gov #NCT01151644)
article 4 Citação(ões) na Scopus Miopatia inflamatória induzida por adalimumab na artrite reumatóide(2012) SOUZA, Fernando Henrique Carlos de; BARROS, Thiago Bitar Morais; LEVY-NETO, Mauricio; SHINJO, Samuel KatsuyukiThe application of immunobiologics for the rheumatoid arthritis treatment may present as a rare complication the development of inflammatory myopathy. 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.- 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.
- Serum 25-hydroxyvitamin D levels in patients with Granulomatosis with Polyangiitis: association with respiratory infection(2017) PEREZ, Mariana O.; OLIVEIRA, Ricardo M.; LEVY-NETO, Mauricio; CAPARBO, Valeria F.; PEREIRA, Rosa M. R.OBJECTIVES: To determine the possible association of serum 25-hydroxyvitamin D (25OHD) levels with disease activity and respiratory infection in granulomatosis with polyangiitis patients during two different periods: winter/spring and summer/autumn. METHODS: Thirty-two granulomatosis with polyangiitis patients were evaluated in the winter/spring, and the same patients (except 5) were evaluated in summer/autumn (n = 27). The 25OHD levels were measured by radioimmunoassay. Disease activity was assessed by the Birmingham Vasculitis Activity Score Modified for Wegener's Granulomatosis (BVAS/WG) and antineutrophil cytoplasmic antibody (ANCA) positivity. Respiratory infection was defined according the Centers for Disease Control and Prevention criteria. RESULTS: 25OHD levels were lower among patients in winter/spring than in summer/autumn (32.31 +/- 13.10 vs. 38.98 +/- 10.97 ng/mL, p= 0.04). Seven patients met the criteria for respiratory infection: 5 in winter/spring and 2 in summer/autumn. Patients with respiratory infection presented lower 25OHD levels than those without infection (25.15 +/- 11.70 vs. 36.73 +/- 12.08 ng/mL, p= 0.02). A higher frequency of low vitamin D levels (25OHD <20 ng/mL) was observed in patients with respiratory infection (37.5% vs. 7.8, p= 0.04). Serum 25OHD levels were comparable between patients with (BVAS/WGX1 plus positive ANCA) and without disease activity (BVAS/WG= 0 plus negative ANCA) (35.40 +/- 11.48 vs. 35.34 +/- 13.13 ng/mL, p = 0.98). CONCLUSIONS: Lower 25OHD levels were associated with respiratory infection but not disease activity in granulomatosis with polyangiitis patients. Our data suggest that hypovitaminosis D could be an important risk factor for respiratory infection in granulomatosis with polyangiitis patients.
- 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.
article 0 Citação(ões) na Scopus Coronary artery bypass grafting from splenic artery in Takayasu arteritis(2015) GARCIA, M. V. F.; CORDEIRO, R. A.; GAIOTTO, F. A.; JATENE, F. B.; SHINJO, S. K.; LEVY-NETO, M.The present report demonstrates that the splenic artery is an option as proximal blood source for saphenous vein grafts for surgical myocardial revascularization in Takayasu arterits (TA). This idiopathic vasculitis affects mainly aorta and its major branches including coronary arteries. A coronary artery bypass grafting (CABG) should be considered when coronary involvement occurs, although, calcification of the vessels affected often makes them unsuitable for use. We report the case of 56 years-old woman who presented unstable angina and multiple arterial involvement, with severe coronary lesions. The patient underwent a CABG with splenic artery as proximal blood source. After surgery, angina was resolved, with good exertional tolerance fora 2 years follow-up period. The surgical treatment of symptomatic TA was effective and safe, showing at complex surgeries without extracorporeal circulation may be greatly beneficial for that group of patients. Symptomatic improvement and excellent long-term graft patency should be expected after arterial reconstruction.
