- 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.
article 9 Citação(ões) na Scopus Anti-Lipoprotein Lipase Antibodies in Patients with Hypertriglyceridemia without Associated Autoimmune Disease(2011) CARVALHO, Jozelio Freire de; VIANA, Vilma Santos Trindade; BORBA NETO, Eduardo Ferreira; SANTOS, Raul Dias; BONFA, EloisaBackground: Anti-lipoprotein lipase antibodies have been described in rare cases of patients with hypertriglyceridemia. However, no systematic study evaluating these antibodies in patients with this lipid abnormality has been undertaken. Objectives: To analyze the correlation of anti-lipoprotein lipase (anti-LPL) antibodies with other laboratory findings in patients with hypertriglyceridemia but no autoimmune disease. Methods: We evaluated 44 hypertriglyceridemic patients without autoimmune disease. Clinical and laboratory evaluations included analyses of comorbidities, fasting lipid profile and anti-LPL antibodies. Results: Mean patient age was 55 +/- 10 years; 46% of the patients were female and 64% were Caucasian. The mean disease duration was 94.4 months and mean body mass index 28.7 +/- 3.6 kg/m(2); 34.0% were diabetic, 25.0% were obese, 72.7% had systemic arterial hypertension, 75% were sedentary, 15.9% were smokers, 56.8% had a family history of dyslipidemia, 45.5% had a family history of coronary insufficiency, 20.5% had acute myocardial infarction, 9.0% had undergone revascularization and 11.0% angioplasty, 79.5% were being treated with statins and 43.2% were taking fibrates. Median triglyceride levels were 254 mg/dl (range 100-3781 mg/dl), and total cholesterol level was 233 +/- 111 mg/dl. High-density lipoprotein was 42.6 +/- 15.4 mg/dl, low-density lipoprotein 110.7 +/- 42.4 mg/dl and very low-density lipoprotein 48 +/- 15 mg/dl. Anti-LPL antibodies were identified in 2 patients (4.5%), both of whom had a family history of dyslipidemia, coronary insufficiency and acute myocardial infarction; one had undergone myocardial revascularization and percutaneous transluminal coronary angioplasty, and both were using fibrates and had normal triglyceride levels. Conclusions: Our findings demonstrate a correlation between the immune response and dyslipoproteinemia in hypertriglyceridemic patients, suggesting that autoimmune disease contributes to the dyslipidemia process.- IL-23/Th17 axis is not influenced by TNF-blocking agents in ankylosing spondylitis patients(2016) MILANEZ, Fernanda Manente; SAAD, Carla G. S.; VIANA, Vilma T.; MORAES, Julio C. B.; PERICO, Gregory Vinicius; SAMPAIO-BARROS, Percival Degrava; GONCALVES, Celio R.; BONFA, EloisaBackground: Advances in pathophysiology and treatment of ankylosing spondylitis (AS) was recently demonstrated. However, the effect of anti-TNF in the newly described inflammatory pathways involved pathogenesis of this disease remains to be determined. The aim of our study was, therefore, to investigate long-term influence of anti-TNF drugs in IL-23/IL-17 axis of AS patients and their possible correlation with treatment, clinical, laboratory and radiographic parameters. Methods: Eighty-six AS anti-TNF naive patients, 47 referred for anti-TNF therapy (active-AS; BASDAI >= 4) and 39 with BASDAI < 4 (control-AS) were included. The active group was evaluated at baseline, 12-months and 24-months after TNF blockade and compared at baseline to control-AS group and to 47 healthy age-and gender-matched controls. Plasma levels of IL-17A, IL-22, IL-23 and PGE2 were measured. Non-steroidal anti-inflammatory drugs (NSAIDs) intake were recorded every 6 months. Radiographic severity and progression was assessed by mSASSS at baseline and 24 months after therapy. Results: At baseline, active-AS group presented higher IL-23 and PGE2 levels compared to control-AS group (p < 0.001 and p = 0.008) and to healthy controls (p < 0.001 and p = 0.02). After 24-months of TNF blockade, IL-23 and PGE2 remained elevated with higher levels compared with the healthy group (p < 0.001 and p = 0.03) in spite of significant improvements in all clinical/inflammatory parameters (p < 0.001). Further analysis of 27 anti-TNF-treated patients who achieved a good response (ASDAS-CRP < 2.1, with a drop >= 1.1) at 24-months revealed that IL-23 plasma levels remained higher than healthy controls (p < 0.001) and higher than control-AS group with similar disease activity (ASDAS-CRP < 2.1, p = 0.01). In active-AS group (n = 47), there was a strong correlation between IL-23 and IL-17A at baseline, 12-months and 24-months after anti-TNF therapy (p <= 0.001). Conclusion: This study provides novel data demonstrating that the IL-23/IL-17 axis is not influenced by TNF blockade in AS patients despite clinical and inflammation improvements and NSAID intake.
- Evidence for cardiac safety and antiarrhythmic potential of chloroquine in systemic lupus erythematosus(2014) TEIXEIRA, Ricardo Alkmim; BORBA, Eduardo F.; PEDROSA, Anisio; NISHIOKA, Silvana; VIANA, Vilma S. T.; RAMIRES, Jose A.; KALIL-FILHO, Roberto; BONFA, Eloisa; MARTINELLI FILHO, MartinoTo perform a comprehensive evaluation of heart rhythm disorders and the influence of disease/therapy factors in a large systemic lupus erythematosus (SLE) cohort. Three hundred and seventeen consecutive patients of an ongoing electronic database protocol were evaluated by resting electrocardiogram and 142 were randomly selected for 24 h Holter monitoring for arrhythmia and conduction disturbances. The mean age was 40.2 +/- 12.1 years and disease duration was11.4 +/- 8.1 years. Chloroquine (CQ) therapy was identified in 69.7% with a mean use of 8.5 +/- 6.7 years. Electrocardiogram abnormalities were detected in 66 patients (20.8%): prolonged QTc/QTd (14.2%); bundle-branch block (2.5%); and atrioventricular block (AVB) (1.6%). Age was associated with AVB (P = 0.029) and prolonged QTc/QTd (P = 0.039) whereas anti-Ro/SS-A and Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) scores were not (P > 0.05). Chloroquine was negatively associated with AVB (P = 0.01) as was its longer use (6.1 +/- 6.9 vs. 1.0 +/- 2.5 years, P = 0.018). Time of CQ use was related with the absence of AVB [odds ratio (OR) = 0.103; 95% confidence interval (CI) = 0.011-0.934, P = 0.043] in multiple logistic regression. Holter monitoring revealed abnormalities in 121 patients (85.2%): supraventricular ectopies (63.4%) and tachyarrhythmia (18.3%); ventricular ectopies (45.8%). Atrial tachycardia/fibrillation (AT/AF) were associated with shorter CQ duration (7.05 +/- 7.99 vs. 3.63 +/- 5.02 years, P = 0.043) with a trend to less CQ use (P = 0.054), and older age (P < 0.001). Predictors of AT/AF in multiple logistic regression were age (OR = 1.115; 95% CI = 1.059-1.174, P < 0.001) and anti-Ro/SS-A (OR = 0.172; 95% CI = 0.047-0.629, P = 0.008). Chloroquine seems to play a protective role in the unexpected high rate of cardiac arrhythmias and conduction disturbances observed in SLE. Further studies are necessary to determine if this antiarrhythmic effect is due to the disease control or a direct effect of the drug.
