- 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.

- Exercise as an Adjuvant Treatment in Persistent Active Polymyositis(2014) MATTAR, Melina Andrade; GUALANO, Bruno; ROSCHEL, Hamilton; PERANDINI, Luiz Augusto; DASSOUKI, Thalita; LIMA, Fernanda Rodrigues; SHINJO, Samuel Katsuyuki; PINTO, Ana Lucia de SaObjectives: A growing number of studies have suggested that exercise may promote therapeutic effects in patients with idiopathic inflammatory myopathy. This prospective case series study aimed to report on the effects of exercise in patients with persistent active myositis. Methods: Three patients with persistent active polymyositis were submitted to a 12-week supervised exercise program comprising both aerobic and strength exercises. Results: After the intervention, the patients presented improvements in selected parameters of muscle function and aerobic conditioning. In addition, an overall improvement was detected in the quality of life, as measured by both the 36-item Short-Form Health Survey and the Health Assessment Questionnaire questionnaires. Importantly, exercise did not increase serum levels of creatine kinase and aldolase. Conclusions: The findings herein suggest that a combined aerobic and strength training program may be tolerable and potentially effective in improving muscle function, aerobic conditioning, and quality of life in patients with persistent active polymyositis.
- Beneficial Effects Of Aerobic Exercise Training On Insulin Sensitivity And Signaling In Systemic Lupus Erythematosus(2016) MIYAKE, Cintia; ROSCHEL, Hamilton; GUALANO, Bruno; DANTAS, Wagner; NEVES, William; PINTO, Ana Lucia de Sa; LIMA, Fernanda; ZAMBELLI, Vanessa; ROSSI, Maria Elizabeth; BONFA, Eloisa; BENATTI, Fabiana B.
- Safety and possible effects of low-intensity resistance training associated with partial blood flow restriction in polymyositis and dermatomyositis(2014) MATTAR, Melina Andrade; GUALANO, Bruno; PERANDINI, Luiz Augusto; SHINJO, Samuel Katsuyuki; LIMA, Fernanda Rodrigues; SA-PINTO, Ana Lucia; ROSCHEL, HamiltonIntroduction: Our aim was to evaluate the safety and efficacy of a low-intensity resistance training program combined with partial blow flow restriction (BFR training) in a cohort of patients with polymyositis (PM) and dermatomyositis (DM). Methods: In total, 13 patients with PM and DM completed a 12-week twice a week low-intensity (that is, 30% one-repetition-maximum (1RM)) resistance exercise training program combined with partial blood flow restriction (BFR). Assessments of muscle strength, physical function, quadriceps cross sectional (CSA) area, health-related quality of life, and clinical and laboratory parameters were assessed at baseline and after the intervention. Results: The BFR training program was effective in increasing the maximal dynamic strength in both the leg-press (19.6%, P < 0.001) and knee-extension exercises (25.2% P < 0.001), as well as in the timed-stands (15.1%, P < 0.001) and timed-up-and-go test (-4.5%, P = 0.002). Quadriceps CSA was also significantly increased after the intervention (4.57%, P = 0.01). Similarly, all of the components of the Short Form-36 Health Survey, the Health Assessment Questionnaire scores, and the patient-and physician reported Visual Analogue Scale were significantly improved after training (P < 0.05). Importantly, no clinical evidence or any other self-reported adverse event were found. Laboratory parameters (creatine kinase and aldolase) were also unchanged (P > 0.05) after the intervention. Conclusions: We demonstrated that a 12-week supervised low-intensity resistance training program associated with partial blood flow restriction may be safe and effective in improving muscle strength and function as well as muscle mass and health-related quality of life in patients with PM and DM.
- Exercise Mitigates Bone Loss in Women With Severe Obesity After Roux-en-Y Gastric Bypass: A Randomized Controlled Trial(2019) MURAI, Igor H.; ROSCHEL, Hamilton; DANTAS, Wagner S.; GIL, Saulo; MEREGE-FILHO, Carlos; CLEVA, Roberto de; SA-PINTO, Ana L. De; LIMA, Fernanda; SANTO, Marco A.; BENATTI, Fabiana B.; KIRWAN, John P.; PEREIRA, Rosa M.; GUALANO, BrunoContext: Bone loss after bariatric surgery potentially could be mitigated by exercise. Objective: To investigate the role of exercise training (ET) in attenuating bariatric surgery-induced bone loss. Design: Randomized, controlled trial. Setting: Referral center for bariatric surgery. Patients: Seventy women with severe obesity, aged 25 to 55 years, who underwent Roux-en-Y gastric bypass (RYGB). Intervention: Supervised, 6-month, ET program after RYGB vs. standard of care (RYGB only). Outcomes: Areal bone mineral density (aBMD) was the primary outcome. Bone microarchitecture, bone turnover, and biochemical markers were secondary outcomes. Results: Surgery significantly decreased femoral neck, total hip, distal radius, and whole body aBMD (P < 0.001); and increased bone turnover markers, including collagen type I C-telopeptide (CTX), procollagen type I N-propeptide (P1NP), sclerostin, and osteopontin (P < 0.05). Compared with RYGB only, exercise mitigated the percent loss of aBMD at femoral neck [estimated mean difference (EMD), -2.91%; P = 0.007;], total hip (EMD, -2.26%; P = 0.009), distal radius (EMD, -1.87%; P = 0.038), and cortical volumetric bone mineral density at distal radius (EMD, -2.09%; P = 0.024). Exercise also attenuated CTX (EMD, -0.20 ng/mL; P = 0.002), P1 NP (EMD, -17.59 ng/mL; P = 0.024), and sclerostin levels (EMD, -610 pg/mL; P = 0.046) in comparison with RYGB. Exercise did not affect biochemical markers (e.g., 25(OH)D, calcium, intact PTH, phosphorus, and magnesium). Conclusion: Exercise mitigated bariatric surgery-induced bone loss, possibly through mechanisms involving suppression in bone turnover and sclerostin. Exercise should be incorporated in postsurgery care to preserve bone mass.
- Quality of life, fatigue, sleep quality, and mental health in systemic lupus erythematosus patients with a high cardiovascular risk profile(2023) MAZZOLANI, Bruna Caruso; SMAIRA, Fabiana Infante; SIECZKOWSKA, Sofia; ROMERO, Marina; RIBEIRO, Thaina Toledo; AMARANTE, Milla Cordeiro; PASOTO, Sandra; PINTO, Ana Lucia de Sa; LIMA, Fernanda Rodrigues; BENATTI, Fabiana Braga; BONFA, Eloisa; ROSCHEL, Hamilton; GUALANO, BrunoSystemic lupus erythematosus (SLE) patients report worse health-related quality of life (HRQL), fatigue, anxiety, depression, and sleep quality, when compared to the general population and other chronic diseases. Furthermore, cardiometabolic diseases are highly prevalent in SLE and are also associated with these parameters. Thus, it is plausible to suggest that SLE patients with a high cardiovascular risk may report worse results for these parameters. The aim of the study is to describe HRQL, fatigue, anxiety and depression symptoms, and sleep quality in a sample of SLE patients with a high cardiovascular risk profile (i.e., BMI between 25 and 40 kg/m2 and/or dyslipidemia, hypertension, or diabetes). This was a cross-sectional study where patients were assessed for (i) demographic, anthropometric, and disease-related parameters, (ii) HRQL, (iii) fatigue, (iv) anxiety and depression symptoms, and (v) sleep quality. One-hundred patients completed the study; however, only 87 patients were assessed for sleep quality data. Patients averaged 41.7 & PLUSMN; 9 years, and most patients were classified as overweight/obese (87%). SF-36 scores for physical and mental components summary were 51.3 & PLUSMN; 9.6 and 54.2 & PLUSMN; 15.6, respectively, with ""bodily pain"" and ""role emotional"" presenting the lower scores. The total SLEQOL score was 105.1 & PLUSMN; 42.0, with lower scores reported for ""self-image"" and ""mood."" Fatigue score was 30.8 & PLUSMN; 8.9, and 78% and 93% reported severe symptoms of anxiety and depression, respectively. The average sleep effectiveness was 82.9 & PLUSMN; 6.6%. Sleep latency, total time in bed (TTiB), and total sleep time (TST) were 8.4 & PLUSMN; 8.9, 495.8 & PLUSMN; 79.7, and 409.7 & PLUSMN; 69.9 min, respectively. Patients reported an average of 17.8 & PLUSMN; 6.2 WE, with 4.5 & PLUSMN; 1.5 min duration and a WASO of 77.7 & PLUSMN; 36.6 min. Despite similar HRQL, fatigue, and sleep quality parameters to those reported by other SLE populations, SLE patients with a high cardiovascular risk had a higher prevalence of depression and anxiety. Understanding SLE patients' quality of life and psychological symptoms is of utmost importance to improve disease management. The findings of this study highlight the need for more intensive and global care regarding mental health when considering a high cardiovascular risk in SLE.
- Abnormal chronotropic reserve and heart rate recovery in patients with SLE: a case-control study(2011) PRADO, D. M. Leite do; GUALANO, B.; MIOSSI, R.; SA-PINTO, A. L.; LIMA, F. R.; ROSCHEL, H.; BORBA, E. F.; BONFA, E.Abnormal heart-rate (HR) response during or after a graded exercise test has been recognized as a strong and an independent predictor of all-cause mortality in healthy and diseased subjects. The purpose of the present study was to evaluate the HR response during exercise in women with systemic lupus erythematosus (SLE). In this case-control study, 22 women with SLE (age 29.5 perpendicular to 1.1 years) were compared with 20 gender-, BMI-, and age-matched healthy subjects (age 26.5 +/- 1.4 years). A treadmill cardiorespiratory test was performed and HR response during exercise was evaluated by the chronotropic reserve (CR). HR recovery (Delta HRR) was defined as the difference between HR at peak exercise and at both first (Delta HRR1) and second (Delta HRR2) minutes after exercising. SLE patients presented lower peak VO(2) when compared with healthy subjects (27.6 perpendicular to 0.9 vs. 36.7 perpendicular to 1.1 ml/kg/min, p = 0.001, respectively). Additionally, SLE patients demonstrated lower CR (71.8 +/- 2.4 vs. 98.2 +/- 2.6%, p = 0.001), Delta HRR1 (22.1 +/- 2.5 vs. 32.4 +/- 2.2%, p = 0.004) and Delta HRR2 (39.1 +/- 2.9 vs. 50.8 +/- 2.5%, p = 0.001) than their healthy peers. In conclusion, SLE patients presented abnormal HR response to exercise, characterized by chronotropic incompetence and delayed Delta HRR. Lupus (2011) 20, 717-720.
- Acute cardiometabolic effects of brief active breaks in sitting for patients with rheumatoid arthritis(2021) PINTO, Ana J.; MEIRELES, Kamila; PECANHA, Tiago; MAZZOLANI, Bruna C.; I, Fabiana Smaira; REZENDE, Diego; BENATTI, Fabiana B.; RIBEIRO, Ana C. M.; PINTO, Ana L. S.; LIMA, Fernanda R.; SHINJO, Samuel K.; DANTAS, Wagner S.; MELLETT, Natalie A.; MEIKLE, Peter J.; OWEN, Neville; DUNSTAN, David W.; ROSCHEL, Hamilton; GUALANO, BrunoExercise is a treatment in rheumatoid arthritis, but participation in moderate-to-vigorous exercise is challenging for some patients. Light-intensity breaks in sitting could be a promising alternative. We compared the acute effects of active breaks in sitting with those of moderate-to-vigorous exercise on cardiometabolic risk markers in patients with rheumatoid arthritis. In a crossover fashion, 15 women with rheumatoid arthritis underwent three 8-h experimental conditions: prolonged sitting (SIT), 30-min bout of moderate-to-vigorous exercise followed by prolonged sitting (EX), and 3-min bouts of light-intensity walking every 30 min of sitting (BR). Postprandial glucose, insulin, c-peptide, triglycerides, cytokines, lipid classes/subclasses (lipidomics), and blood pressure responses were assessed. Muscle biopsies were collected following each session to assess targeted proteins/genes. Glucose [-28% in area under the curve (AUC), P = 0.036], insulin (-28% in AUC, P = 0.016), and c-peptide (-27% in AUC, P = 0.006) postprandial responses were attenuated in BR versus SIT, whereas only c-peptide was lower in EX versus SIT (-20% in AUC, P = 0.002). IL-1 beta decreased during BR, but increased during EX and SIT (P = 0.027 and P = 0.085, respectively). IL-1ra was increased during EX versus BR (P = 0.002). TNF-alpha concentrations decreased during BR versus EX (P = 0.022). EX, but not BR, reduced systolic blood pressure (P = 0.013). Lipidomic analysis showed that 7 of 36 lipid classes/subclasses were significantly different between conditions, with greater changes being observed in EX. No differences were observed for protein/gene expression. Brief active breaks in sitting can offset markers of cardiometabolic disturbance, which may be particularly useful for patients who may find it difficult to adhere to exercise. NEW & NOTEWORTHY Exercise is a treatment in rheumatoid arthritis but is challenging for some patients. Light-intensity breaks in sitting could be a promising alternative. Our findings show beneficial, but differential, cardiometabolic effects of active breaks in sitting and exercise in patients with rheumatoid arthritis. Breaks in sitting mainly improved glycemic and inflammatory markers, whereas exercise improved lipidomic and hypotensive responses. Breaks in sitting show promise in offsetting aspects of cardiometabolic disturbance associated with prolonged sitting in rheumatoid arthritis.
- The effects of exercise on lipid profile in systemic lupus erythematosus and healthy individuals: a randomized trial(2015) BENATTI, Fabiana Braga; MIOSSI, Renata; PASSARELI, Marisa; NAKANDAKARE, Edna R.; PERANDINI, Luiz; LIMA, Fernanda Rodrigues; ROSCHEL, Hamilton; BORBA, Eduardo; BONFA, Eloisa; GUALANO, Bruno; PINTO, Ana Lucia de SaThe aim of the present study was to evaluate the effects of an exercise training program on lipid profile and composition of high-density lipoprotein (HDL) subfractions in systemic lupus erythematosus (SLE) patients and healthy controls. A 12-week, randomized trial was conducted. Thirty-three physically inactive SLE patients were randomly assigned into two groups: trained (SLE-TR, n = 17) and non-trained (SLE-NT, n = 16). A gender-, BMI-, and age-matched healthy control groups (C-TR, n = 11) also underwent the exercise program. Subjects were assessed at baseline (Pre) and 12 weeks after the 3-month exercise training program (Post) for lipid profile (HDL, low-density lipoprotein, very low-density lipoprotein, and total cholesterol and triglycerides levels) and composition of the HDL subfractions HDL2 and HDL3. SLE patients showed significantly lower contents of Apo A-I, phospholipid, and triglyceride in the HDL3 subfraction (p < 0.05, between-group comparisons) than healthy controls at baseline. The exercise training program did not affect any of the parameters in the SLE-TR group (p > 0.05, within-group comparisons), although there was a trend toward decreased circulating Apo B levels (p = 0.06, ES = -0.3, within-group comparison). In contrast, the same exercise training program was effective in increasing contents of cholesterol, triglyceride, and phospholipid in the HDL2 subfraction in the C-TR group (p = 0.036, ES = 2.06; p = 0.038, ES = 1.77; and p = 0.0021, ES = 2.37, respectively, within-group comparisons), whereas no changes were observed in the composition of the HDL3 subfraction. This study showed that SLE patients have a less effective response to a 12-week exercise training program than healthy individuals, with regard to lipid profile and chemical composition of HDL subfractions. These results reinforce the need for further studies to define the optimal training protocol to improve lipid profile and particularly the HDL composition in these patients (registered at clinicaltrials.gov as NCT01515163).
