- Creatine Supplementation in Fibromyalgia: A Randomized, Double-Blind, Placebo-Controlled Trial(2013) ALVES, Christiano R. R.; SANTIAGO, Bianca M.; LIMA, Fernanda R.; OTADUY, Maria C. G.; CALICH, Ana Luisa; TRITTO, Aline C. C.; PINTO, Ana Lucia de Sa; ROSCHEL, Hamilton; LEITE, Claudia C.; BENATTI, Fabiana B.; BONFA, Eloisa; GUALANO, BrunoObjective. To investigate the efficacy and safety of creatine supplementation in fibromyalgia patients. Methods. A 16-week, randomized, double-blind, placebo-controlled, parallel-group trial was conducted. Fibromyalgia patients were randomly assigned to receive either creatine monohydrate or placebo in a double-blind manner. The patients were evaluated at baseline and after 16 weeks. Muscle function, aerobic conditioning, cognitive function, quality of sleep, quality of life, kidney function, and adverse events were assessed. Muscle phosphorylcreatine content was measured through P-31 magnetic resonance spectroscopy. Results. After the intervention, the creatine group presented higher muscle phosphorylcreatine content when compared with the placebo group (+80.3% versus -2.7%; P = 0.04). Furthermore, the creatine group presented greater muscle strength than the placebo group in the leg press and chest press exercises (+9.8% and +1.2% for creatine versus -0.5% and -7.2% for placebo, respectively; P = 0.02 and P = 0.002, respectively). Isometric strength was greater in the creatine group than in the placebo group (+6.4% versus -3.2%; P = 0.007). However, no general changes were observed in aerobic conditioning, pain, cognitive function, quality of sleep, and quality of life. Food intake remained unaltered and no side effects were reported. Conclusion. Creatine supplementation increased intramuscular phosphorylcreatine content and improved lower- and upper-body muscle function, with minor changes in other fibromyalgia features. These findings introduce creatine supplementation as a useful dietary intervention to improve muscle function in fibromyalgia patients.

R.; CAMPOS, Lucia M. A.; BORBA, Eduardo F.; BONFA, Eloisa; SILVA, Clovis A.- A long-term prospective randomized controlled study of non-specific interstitial pneumonia (NSIP) treatment in scleroderma(2011) DOMICIANO, Diogo S.; BONFA, Eloisa; BORGES, Claudia T. L.; KAIRALLA, Ronaldo A.; CAPELOZZI, Vera L.; PARRA, Edwin; CHRISTMANN, Romy BeatrizThe association of cyclophosphamide (CYC) and prednisone (PRED) for the treatment of lung fibrosis in systemic sclerosis (SSc) was only evaluated in uncontrolled studies, although in idiopathic interstitial lung disease (ILD) this association seems to be beneficial in patients with non-specific interstitial pneumonia (NSIP). Objectives: To treat SSc-ILD in a prospective open-label controlled study based on lung pattern during 12 months of treatment. Methods: A 3-year analysis was also performed. Twenty-four consecutive patients with SSc and ILD were submitted to an open lung biopsy. Eighteen patients (NSIP) were randomized in two groups: CYC versus CYC + PRED during 12 months. Lung function tests (diffusion lung capacity of monoxide carbone corrected for hemoglobin concentration (DLCO-Hb), forced vital capacity (FVC), total lung capacity) and Modified Rodnan Skin Score (MRSS) were performed before, after one of treatment and after 3 years from the end of the treatment. Results: Pulmonary function tests were similar in both groups on baseline. After 1 year of treatment, FVC% was comparable between CYC groups (p = 0.72) and in CYC + PRED (p = 0.40). Three years after the end of treatment, FVC% values (p = 0.39 in group CYC and p = 0.61 in CYC + PRED and p = 0.22 in CYC + PRED) and DLCO-Hb (p = 0.54 in CYC and p = 0.28 in CYC + PRED) were similar compared to 1 year of treatment. We observed a reduction of the MRSS in the CYC + PRED group after 1 year of treatment (p = 0.02); although after 3 years, MRSS values remained stable in both groups. Conclusions: CYC was effective to stabilize lung function parameters in NSIP lung pattern of SSc disease for 3 years after the end of a 1-year therapy.
- O ozônio diminui a qualidade do sêmen em pacientes com lúpus eritematoso sistêmico(2016) FARHAT, Juliana; FARHAT, Sylvia Costa Lima; BRAGA, Alfesio Luis Ferreira; COCUZZA, Marcello; BORBA, Eduardo Ferreira; BONFA, Eloisa; SILVA, Clovis ArturObjective: To investigate the deleterious effects of air pollutants exposure in the Sao Paulo metropolitan region on semen quality in systemic lupus erythematosus (SLE). Methods: A seven-years longitudinal repeated-measures panel study was performed at the Laboratory of Experimental Air Pollution and Rheumatology Division. Two semen samples from 28 post-pubertal SLE patients were analyzed. Daily concentrations of air pollutants exposure: PM10, SO2, NO2, ozone, CO, and meteorological variables were evaluated on 90 days before each semen collection dates using generalized estimating equation models. Results: Intravenous cyclophosphamide (IVCYC) and ozone had an association with a decrease in sperm quality of SLE patients. IVCYC was associated with decreases of 64.3 million of spermatozoa/mL (95% CI 39.01-89.65; p = 0.0001) and 149.14 million of spermatozoa/ejaculate (95% CI 81.93-216.38; p = 0.017). With regard to ozone, the most relevant adverse effects were observed from lags 80-88, when the exposure to an interquartile range increase in ozone 9-day moving average concentration led to decreases of 22.9 million of spermatozoa/mL (95% CI 5.8-40.0; p = 0.009) and 70.5 million of spermatozoa/ejaculate (95% CI 12.3-128.7; p = 0.016). Further analysis of 17 patients that never used IVCYC showed association between exposure to ozone (80-88 days) and decrease of 30.0 million of spermatozoa/mL (95% CI 7.0-53.0; p = 0.011) and 79.0 million of spermatozoa/ejaculate (95% CI 2.1-155.9; p = 0.044). Conclusion: Ozone and IVCYC had a consistent adverse effect on semen quality of SLE patients during spermatogenesis. Minimizing exposure to air pollution should be taken into account, especially for patients with chronic systemic inflammatory diseases living in large cities.
conferenceObject Induction of Lupus Nephritisin in Real Situation: Cyclophosphamide or Mycophenolate Mofetil?(2017) MUNHOZ, Gabriela; LACERDA, Maira; LOPES, Michelle; BORBA, Eduardo Ferreira; SEGURO, Luciana; BONFA, Eloisa- Exercise training can attenuate the inflammatory milieu in women with systemic lupus erythematosus(2014) PERANDINI, Luiz A.; SALES-DE-OLIVEIRA, Diego; MELLO, Suzana B. V.; CAMARA, Niels O.; BENATTI, Fabiana B.; LIMA, Fernanda R.; BORBA, Eduardo; BONFA, Eloisa; SA-PINTO, Ana L.; ROSCHEL, Hamilton; GUALANO, BrunoSystemic lupus erythematosus (SLE) is an autoimmune disease characterized by chronic inflammation. This study sought to assess the effects of an exercise training program on cytokines and soluble TNF receptors (sTNFRs) in response to acute exercise in SLE women. Eight SLE women and 10 sex-, age-, and body mass index-comparable healthy controls (HC) participated in this study. Before and after a 12-wk aerobic exercise training program, cytokines and sTNFRs were assessed at rest and in response to single bouts of acute moderate/intense exercise. HC performed the acute exercise bouts only at baseline. After the exercise training program, there was a decrease in resting TNFR2 levels (P = 0.025) and a tend to reduction interleukin (IL)-10 levels (P = 0.093) in SLE. The resting levels of IL-6, IL-10, and TNF-alpha after the exercise training in SLE reached HC levels (P > 0.05). In response to a single bout of acute moderate exercise, the area under the curve (AUC) of IL-10 was significantly reduced after the exercise training program in SLE (P = 0.043), and the AUC of IL-10, IL-6, TNF-alpha, and sTNFR1 of SLE approached control values (P = 0.05). In response to a single bout of acute intense exercise, the AUC of IL-10 was significantly reduced in SLE (P = 0.015). Furthermore, the AUC of sTNFR2 tended to decrease after exercise training program in SLE (P = 0.084), but it did not reach control values (P = 0.001). An aerobic exercise training program attenuated the inflammatory milieu in SLE women, revealing a novel homeostatic immunomodulatory role of exercise in an autoimmunity condition.

- Erratic control of breathing during exercise in patients with systemic lupus erythematosus: a pilot-study(2011) PRADO, D. M. L. do; GUALANO, B.; MIOSSI, R.; LIMA, F. R.; ROSCHEL, H.; BORBA, E.; BONFA, E.; PINTO, A. L. de SaPurpose: The aim of this study was to provide a comprehensive evaluation of the pattern and timing of breathing during incremental exercise in a sample of women living with systemic lupus erythematosus (SLE). Methods: In this cross-sectional study, 20 women with SLE without pulmonary involvement were compared with 20 gender-, body mass index- (BMI), and age-matched healthy individuals. By using a cardiopulmonary incremental exercise test, the following parameters were assessed: tidal volume (VT); breathing frequency (BF); total respiratory time (TOT); inspiratory time (TI); expiratory time (TE); inspiratory time to total time (TI/TOT); mean inspiratory flow (VT/TI); ventilatory equivalent for carbon dioxide (VE/VCO(2)) and end-tidal carbon dioxide pressure (PETCO(2)). Results: BF and BF/VT were significantly higher in patients with SLE versus controls, whereas VT, TE, TI and TOT were significantly lower in the former group (p < 0.05). Additionally, patients with SLE presented higher VE/VCO(2) and lower PETCO(2) than controls (p < 0.05), suggesting a ventilatory inefficiency. Conclusion: We reported compelling evidence of abnormal pattern and timing of breathing during incremental exercise in SLE. Considering that an erratic control of breathing may play an important role in exercise intolerance and fatigue, respiratory exercises emerge as a potential treatment for these symptoms in patients with SLE.

- Safety and immunogenicity of influenza A(H3N2) component vaccine in juvenile systemic lupus erythematosus(2023) AIKAWA, Nadia Emi; BORBA, Eduardo Ferreira; BALBI, Verena Andrade; SALLUM, Adriana Maluf Elias; BUSCATTI, Izabel Mantovani; CAMPOS, Lucia Maria Arruda; KOZU, Katia Tomie; GARCIA, Cristiana Couto; CAPAO, Artur Silva Vidal; PROENCA, Adriana Coracini Tonacio de; LEON, Elaine Pires; DUARTE, Alberto Jose da Silva; LOPES, Marta Heloisa; SILVA, Clovis Artur; BONFA, EloisaIntroduction Seasonal influenza A (H3N2) virus is an important cause of morbidity and mortality in the last 50 years in population that is greater than the impact of H1N1. Data assessing immunogenicity and safety of this virus component in juvenile systemic lupus erythematosus (JSLE) is lacking in the literature.Objective To evaluate short-term immunogenicity and safety of influenza A/Singapore (H3N2) vaccine in JSLE.Methods 24 consecutive JSLE patients and 29 healthy controls (HC) were vaccinated with influenza A/Singapore/INFIMH-16-0019/2016(H3N2)-like virus. Influenza A (H3N2) seroprotection (SP), seroconversion (SC), geometric mean titers (GMT), factor increase in GMT (FI-GMT) titers were assessed before and 4 weeks post-vaccination. Disease activity, therapies and adverse events (AE) were also evaluated.Results JSLE patients and controls were comparable in current age [14.5 (10.1-18.3) vs. 14 (9-18.4) years, p = 0.448] and female sex [21 (87.5%) vs. 19 (65.5%), p = 0.108]. Before vaccination, JSLE and HC had comparable SP rates [22 (91.7%) vs. 25 (86.2%), p = 0.678] and GMT titers [102.3 (95% CI 75.0-139.4) vs. 109.6 (95% CI 68.2-176.2), p = 0.231]. At D30, JSLE and HC had similar immune response, since no differences were observed in SP [24 (100%) vs. 28 (96.6%), p = 1.000)], SC [4 (16.7%) vs. 9 (31.0%), p = 0.338), GMT [162.3 (132.9-198.3) vs. 208.1 (150.5-287.8), p = 0.143] and factor increase in GMT [1.6 (1.2-2.1) vs. 1.9 (1.4-2.5), p = 0.574]. SLEDAI-2K scores [2 (0-17) vs. 2 (0-17), p = 0.765] and therapies remained stable throughout the study. Further analysis of possible factors influencing vaccine immune response among JSLE patients demonstrated similar GMT between patients with SLEDAI < 4 compared to SLEDAI >= 4 (p = 0.713), as well as between patients with and without current use of prednisone (p = 0.420), azathioprine (p = 1.0), mycophenolate mofetil (p = 0.185), and methotrexate (p = 0.095). No serious AE were reported in both groups and most of them were asymptomatic (58.3% vs. 44.8%, p = 0.958). Local and systemic AE were alike in both groups (p > 0.05).Conclusion This is the first study that identified adequate immune protection against H3N2-influenza strain with additional vaccine-induced increment of immune response and an adequate safety profile in JSLE.
