- Increased physical activity reduces sleep disturbances in asthma: A randomized controlled trial(2023) PASSOS, Natalia Febrini; FREITAS, Patricia D.; CARVALHO-PINTO, Regina Maria; CUKIER, Alberto; CARVALHO, Celso R. F.Background and objective Individuals with asthma are more likely to develop sleep-disordered breathing. Exercise training improves sleep; however, the effect of physical activity (PA) on improving sleep quality remains unknown. This study had two objectives: (i) to evaluate the effect of a behavioural intervention to increase physical activity in daily living (PADL) on sleep quality in adults with asthma; (ii) to verify the association between a change in sleep quality, quality of life, anxiety, depression and asthma symptoms. Methods This randomized controlled clinical trial included adults physically inactive with asthma. Participants were randomized into the control (CG; n = 25) and intervention groups (IG; n = 24). IG was submitted to a behavioural intervention to increase PADL, and CG received the usual care. Pre- and post-intervention assessments of sleep quality (by actigraphy and questionnaire), PADL level (by accelerometry), asthma control, health-related quality of life and anxiety and depression levels were conducted. Results Both groups were similar at baseline. After the intervention, IG increased daily steps and moderate to vigorous PA levels. IG also improved sleep efficiency and latency as well as increased asthma-symptom-free days compared to CG. In addition, a greater proportion of participants in the IG had improved sleep quality after the intervention. Lastly, IG presented clinical improvement in the asthma-related quality of life questionnaire and a reduction in anxiety symptoms. Conclusion Our results demonstrate that a behavioural intervention can increase PA, enhance behavioural sleep quality, efficiency and quality of life and reduce asthma and anxiety symptoms.
- 2020 Brazilian Thoracic Association recommendations for the management of asthma(2020) PIZZICHINI, Marcia Margaret Menezes; CARVALHO-PINTO, Regina Maria de; CANCADO, Jose Eduardo Delfini; RUBIN, Adalberto Sperb; CERCI NETO, Alcindo; CARDOSO, Alexandre Pinto; CRUZ, Alvaro Augusto; FERNANDES, Ana Luisa Godoy; BLANCO, Daniella Cavalet; VIANNA, Elcio Oliveira; CORDEIRO JUNIOR, Gediel; RIZZO, Jose Angelo; FRITSCHER, Leandro Genehr; CAETANO, Lilian Serrasqueiro Ballini; PEREIRA, Luiz Fernando Ferreira; RABAHI, Marcelo Fouad; OLIVEIRA, Maria Alenita de; LIMA, Marina Andrade; ALMEIDA, Marina Buarque de; STELMACH, Rafael; PITREZ, Paulo Marcio; CUKIER, AlbertoThe pharmacological management of asthma has changed considerably in recent decades, as it has come to be understood that it is a complex, heterogeneous disease with different phenotypes and endotypes. It is now clear that the goal of asthma treatment should be to achieve and maintain control of the disease, as well as to minimize the risks (of exacerbations, disease instability, accelerated loss of lung function, and adverse treatment effects). That requires an approach that is personalized in terms of the pharmacological treatment, patient education, written action plan, training in correct inhaler use, and review of the inhaler technique at each office visit. A panel of 22 pulmonologists was invited to perform a critical review of recent evidence of pharmacological treatment of asthma and to prepare this set of recommendations, a treatment guide tailored to use in Brazil. The topics or questions related to the most significant changes in concepts, and consequently in the management of asthma in clinical practice, were chosen by a panel of experts. To formulate these recommendations, we asked each expert to perform a critical review of a topic or to respond to a question, on the basis of evidence in the literature. In a second phase, three experts discussed and structured all texts submitted by the others. That was followed by a third phase, in which all of the experts reviewed and discussed each recommendation. These recommendations, which are intended for physicians involved in the treatment of asthma, apply to asthma patients of all ages.
- Identifying the Characteristics of Responders and Nonresponders in a Behavioral Intervention to Increase Physical Activity Among Patients With Moderate to Severe Asthma: Protocol for a Prospective Pragmatic Study(2023) LIMA, Fabiano Francisco de; LUNARDI, Adriana Claudia; PINHEIRO, David Halen Araujo; CARVALHO-PINTO, Regina Maria; STELMACH, Rafael; GIAVINA-BIANCHI, Pedro; AGONDI, Rosana Camara; CARVALHO, Celso R. F.Background: Previous research has suggested that most adults improve their asthma control after a short-term behavioral intervention program to increase physical activity in daily life (PADL). However, the characteristics of individuals who respond and do not respond to this intervention and the medium-term response remain unknown.Objective: This study aims to (1) identify the characteristics of adult responders and nonresponders with asthma to a behavioral intervention to increase physical activity and (2) evaluate the functional and clinical benefits in the medium term.Methods: This prospective pragmatic study will include adults with moderate to severe asthma who enroll in a behavioral intervention. All individuals will receive an educational program and an 8-week intervention to increase PADL (1 time/wk; up to 90 min/session). The educational program will be conducted in a class setting through group discussions and video presentations. Behavioral interventions will be based on the transtheoretical model using counseling, incentives, and individual feedback aiming to increase participation in physical activity. Motivational interviewing and guidelines for overcoming barriers will be used to stimulate individuals to reach their goals. Pre-and postintervention assessments will include the following: PADL (triaxial accelerometry), body composition (octopolar bioimpedance), barriers to PADL (questionnaire), clinical asthma control (Asthma Control Questionnaire), quality of life (Asthma Quality of Life Questionnaire), anxiety and depression levels (Hospital Anxiety and Depression Scale), and exacerbations. ""Responders"" to the intervention will be defined as those who demonstrate an increase in the number of daily steps (& GE;2500). Results: In December 2021, the clinical trial registration was approved. Recruitment and data collection for the trial is ongoing, and the results of this study are likely to be published in late 2024. Conclusions: The intervention will likely promote different effects according to the clinical characteristics of the individuals, including asthma control, age, anxiety and depression levels, obesity, and several comorbidities. Identifying individuals who respond or do not respond to behavioral interventions to increase PADL will help clinicians prescribe specific interventions to adults with asthma.Trial Registration: ClinicalTrials.gov NCT05159076; https://clinicaltrials.gov/ct2/show/NCT05159076International Registered Report Identifier (IRRID): DERR1-10.2196/49032
- Identification of asthma phenotypes based on extrapulmonary treatable traits(2021) FREITAS, Patricia Duarte; XAVIER, Rafaella Franca; MCDONALD, Vanessa Marie; GIBSON, Peter Gerard; CORDOVA-RIVERA, Laura; FURLANETTO, Karina Couto; OLIVEIRA, Joice Mara de; CARVALHO-PINTO, Regina Maria; CUKIER, Alberto; STELMACH, Rafael; CARVALHO, Celso Ricardo FernandesAsthma is a heterogeneous and complex disease, and a description of asthma phenotypes based on extrapulmonary treatable traits has not been previously reported. The objective of this study was to identify and characterise clusters based on clinical, functional, anthropometrical and psychological characteristics in participants with moderate-to-severe asthma. This was a cross-sectional multicentre study involving centres from Brazil and Australia. Participants (n=296) with moderate-to-severe asthma were consecutively recruited. Physical activity and sedentary time, clinical asthma control, anthropometric data, pulmonary function and psychological and health status were evaluated. Participants were classified by hierarchical cluster analysis and the clusters compared using ANOVA, Kruskal Wallis and Chi-squared tests. Multiple logistic and linear regression models were performed to evaluate the association between variables. We identified four clusters: 1) participants with controlled asthma who were physically active, 2) participants with uncontrolled asthma who were physically inactive and more sedentary; 3) participants with uncontrolled asthma and low physical activity, who were also obese and experienced anxiety and/or depression symptoms; and 4) participants with very uncontrolled asthma who were physically inactive, more sedentary, obese and experienced anxiety and/or depression symptoms. Higher levels of sedentary time, female sex and anxiety symptoms were associated with increased odds of exacerbation risk, while being more active showed a protective factor for hospitalisation. Asthma control was associated with sex, the occurrence of exacerbation, physical activity and health status. Physical inactivity, obesity and symptoms of anxiety and/or depression were associated with worse asthma outcomes, and closely and inextricably associated with asthma control. This cluster analysis highlights the importance of assessing extrapulmonary traits to improve personalised management and outcomes for people with moderate and severe asthma.
- Identification of Phenotypes in People with COPD: Influence of Physical Activity, Sedentary Behaviour, Body Composition and Skeletal Muscle Strength(2019) XAVIER, Rafaella F.; PEREIRA, Ana Carolina A. C.; LOPES, Aline C.; CAVALHERI, Vinicius; PINTO, Regina M. C.; CUKIER, Alberto; RAMOS, Ercy M. C.; CARVALHO, Celso R. F.Introduction People with chronic obstructive pulmonary disease (COPD) present high prevalence of physical inactivity that leads to a negative effect on health-related quality of life (HRQoL). The present study investigated COPD phenotypes according to their levels of physical activity and sedentary behaviour, as well as body composition and skeletal muscle strength. Methods This is an observational and cross-sectional study. Anthropometric data and COPD clinical control were collected and all participants underwent assessments of lung function, HRQoL, dyspnoea, levels of physical activity and sedentary behaviour, body composition and skeletal muscle strength. Participants were classified using hierarchical cluster analysis. Age, dyspnoea and obstruction (ADO) index was used to determine prognosis and calculated for each cluster. Results One hundred and fifty-two participants were included. Three distinct phenotypes were identified. Participants in phenotype 1 were more physically active, less sedentary and had better body composition and lower ADO index (p < 0.0001 for all variables). Overall, participants in phenotypes 2 and 3 were less physically active, more sedentary having a higher ADO index. However, participants in phenotype 2 were older, whereas participants in phenotype 3 had worse HRQoL, clinical control and body composition. Lung function did not differ across the three phenotypes. Conclusions Our results show that physical activity, sedentary behaviour and body composition should be considered to determine phenotypes in people with COPD and are involved in the prognosis of the disease. Less sedentary patients have better prognosis while age, body composition and clinical control seems to differentiate physically inactive patients.
- The Role of Exercise in a Weight-Loss Program on Clinical Control in Obese Adults with Asthma A Randomized Controlled Trial(2017) FREITAS, Patricia D.; FERREIRA, Palmira G.; SILVA, Aline G.; STELMACH, Rafael; CARVALHO-PINTO, Regina M.; FERNANDES, Frederico L. A.; MANCINI, Marcia C.; SATO, Maria N.; MARTINS, Milton A.; CARVALHO, Celso R. F.Rationale: Clinical control is difficult to achieve in obese patients with asthma. Bariatric surgery has been recommended for weight loss and to improve asthma control; however, the benefits of nonsurgical interventions have been poorly investigated. Objectives: To examine the effect of exercise training in a weight loss program on asthma control, quality of life, inflammatory biomarkers, and lung function. Methods: Fifty-five obese patients with asthma were randomly assigned to either a weight-loss program plus exercise (WL + E group, n = 28) or a weight-loss program plus sham (WL + S group, n = 27), where the weight-loss program included nutrition (caloric restriction) and psychological therapies. The WL + E group incorporated aerobic and resistance muscle training, whereas the WL + S group incorporated breathing and stretching exercises. Measurements and Main Results: The primary outcome was clinical improvement in asthma control over 3 months. Secondary outcomes included quality of life, lung function, body composition, aerobic capacity, muscle strength, and inflammatory/antiinflammatory biomarkers. After 3 months, 51 patients were analyzed. Compared with the WL + S group, the WL + E group demonstrated improved clinical control scores (median [25th to 75th percentile],-0.7 [-1.3 to -0.3] vs. -0.3 [-0.9 to 0.4]; P = 0.01) and greater weight loss (mean +/- SD, -6.8% +/- 3.5 vs. -3.1% +/- 2.6; P < 0.001) and aerobic capacity (median [25th to 75th percentile], 3.0 [2.4 to 4.0] vs. 0.9 [-0.3 to 1.3] ml O-2 X kg(-1) X min(-1); P < 0.001). These improvements in the WL + E group were also accompanied by improvements in lung function, antiinflammatory biomarkers, and vitamin D levels, as well as reductions in airway and systemic inflammation. Conclusions: Adding exercise to a short-term weight-loss program should be considered as a useful strategy for achieving clinical control of asthma in obese patients.
- Aerobic training decreases bronchial hyperresponsiveness and systemic inflammation in patients with moderate or severe asthma: a randomised controlled trial(2015) FRANCA-PINTO, Andrezza; MENDES, Felipe A. R.; CARVALHO-PINTO, Regina Maria de; AGONDI, Rosana Camara; CUKIER, Alberto; STELMACH, Rafael; SARAIVA-ROMANHOLO, Beatriz M.; KALIL, Jorge; MARTINS, Milton A.; GIAVINA-BIANCHI, Pedro; CARVALHO, Celso R. F.Background The benefits of aerobic training for the main features of asthma, such as bronchial hyperresponsiveness (BHR) and inflammation, are poorly understood. We investigated the effects of aerobic training on BHR (primary outcome), serum inflammatory cytokines (secondary outcome), clinical control and asthma quality of life (Asthma Quality of Life Questionnaire (AQLQ)) (tertiary outcomes). Methods Fifty-eight patients were randomly assigned to either the control group (CG) or the aerobic training group (TG). Patients in the CG (educational programme+breathing exercises (sham)) and the TG (same as the CG+aerobic training) were followed for 3 months. BHR, serum cytokine, clinical control, AQLQ, induced sputum and fractional exhaled nitric oxide (FeNO) were evaluated before and after the intervention. Results After 12 weeks, 43 patients (21 CG/22 TG) completed the study and were analysed. The TG improved in BHR by 1 doubling dose (dd) (95% CI 0.3 to 1.7 dd), and they experienced reduced interleukin 6 (IL-6) and monocyte chemoattractant protein 1 (MCP-1) and improved AQLQ and asthma exacerbation (p<0.05). No effects were seen for IL-5, IL-8, IL-10, sputum cellularity, FeNO or Asthma Control Questionnaire 7 (ACQ-7; p>0.05). A within-group difference was found in the ACQ-6 for patients with non-well-controlled asthma and in sputum eosinophil and FeNO in patients in the TG who had worse airway inflammation. Conclusions Aerobic training reduced BHR and serum proinflammatory cytokines and improved quality of life and asthma exacerbation in patients with moderate or severe asthma. These results suggest that adding exercise as an adjunct therapy to pharmacological treatment could improve the main features of asthma.
- 2021 Brazilian Thoracic Association recommendations for the management of severe asthma(2021) CARVALHO-PINTO, Regina Maria de; CANCADO, Jose Eduardo Delfini; PIZZICHINI, Marcia Margaret Menezes; FITERMAN, Jussara; RUBIN, Adalberto Sperb; CERCI NETO, Alcindo; CRUZ, Alvaro Augusto; FERNANDES, Ana Luisa Godoy; ARAUJO, Ana Maria Silva; BLANCO, Daniela Cavalet; CORDEIRO JUNIOR, Gediel; CAETANO, Lilian Serrasqueiro Ballini; RABAHI, Marcelo Fouad; MENEZES, Marcelo Bezerra de; OLIVEIRA, Maria Alenita de; LIMA, Marina Andrade; PITREZ, Paulo MarcioAdvances in the understanding that severe asthma is a complex and heterogeneous disease and in the knowledge of the pathophysiology of asthma, with the identification of different phenotypes and endotypes, have allowed new approaches for the diagnosis and characterization of the disease and have resulted in relevant changes in pharmacological management. In this context, the definition of severe asthma has been established, being differentiated from difficult-to-control asthma. These recommendations address this topic and review advances in phenotyping, use of biomarkers, and new treatments for severe asthma. Emphasis is given to topics regarding personalized management of the patient and selection of biologicals, as well as the importance of evaluating the response to treatment. These recommendations apply to adults and children with severe asthma and are targeted at physicians involved in asthma treatment. A panel of 17 Brazilian pulmonologists was invited to review recent evidence on the diagnosis and management of severe asthma, adapting it to the Brazilian reality. Each of the experts was responsible for reviewing a topic or question relevant to the topic. In a second phase, four experts discussed and structured the texts produced, and, in the last phase, all experts reviewed and approved the present manuscript and its recommendations.
- Clinical characteristics and possible phenotypes of an adult severe asthma population(2012) CARVALHO-PINTO, Regina Maria de; CUKIER, Alberto; ANGELINI, Luciene; ANTONANGELO, Leila; MAUAD, Thais; DOLHNIKOFF, Marisa; RABE, Klaus F.; STELMACH, RafaelBackground: Currently, there are no studies of well-characterized severe asthmatics in Brazil. We aimed to study a population of severe treated asthmatics still uncontrolled to characterize them and define possible phenotypes. Methods: Descriptive cross-sectional outpatient study of severe asthmatics, evaluating functional and inflammatory markers, health-related quality of life, anxiety and depression symptoms, clinical control status, and characteristics related to atopy, age of asthma onset, induced sputum eosinophil levels, and airflow limitation. We also grouped the subgroups characteristics to identify phenotypes. The study is registered on ClinicalTrial.gov NCT 01089322. Results: From 128 eligible patients with severe/uncontrolled asthma, 74 fulfilled the inclusion criteria. The cohort was comprised of 85% women, frequently with a body mass index higher than 31 kg m(-2), atopy (60%), early-onset disease (50%), sputum eosinophilia (80%), comorbidities, and reduced quality of life. Nonatopics had significant higher asthma onset (19 y.a.) and twice level of induced sputum eosinophil. Late-onset patients had significantly less atopy (57%) and higher levels of induced sputum eosinophils. Non-eosinophilics had lower levels of inflammatory markers. Patients with airflow limitation had more intensive care unit admissions (56%) and 1.5 times more airway resistance. Subgroups characteristics identified a priori four well-characterized phenotypes, with 55% presenting sputum eosinophilia. Conclusion: Our data emphasize the high burden of disease, the persistence of inflammation and the existence of clinical possible phenotypes population sharing common features with published cohorts. Despite the necessity of further investigation into pathogenic mechanisms, this study with clinically difficult patient group may help to improve future asthma care.
- Effects of weight loss on dynamic hyperinflation in obese women asthmatics(2019) SILVA, Aline Grandi; FREITAS, Patricia Duarte; FERREIRA, Palmira Gabriele; STELMACH, Rafael; CARVALHO-PINTO, Regina Maria; SALGE, Joao Marcos; MARTINS, Milton Arruda; CARVALHO, Celso R. F.Obese adults with asthma are more likely to develop dynamic hyperinflation (DH) and expiratory flow limitation (EFL) than nonobese asthmatics, and weight-loss seems to improve the breathing mechanics during exercise. However, studies evaluating the effect of weight loss on DH in obese adults with asthma have not been performed. We sought to evaluate the effect of a weight loss program on DH in obese adults with asthma. Forty-two asthma patients were enrolled in a weight loss program (diet, psychological support, and exercise) and were subsequently divided into two groups according to the percentage of weight loss: a >= 5% group (n = 19) and a <5% group (n = 23). Before and after the intervention. DH and EFL (constant load exercise), health-related quality of life (HRQoL). asthma control, quadriceps muscle strength and endurance, body composition, and lung function were assessed. Both groups exhibited a decrease of >= 10% in inspiratory capacity (DH) before intervention, and only the >= 5% group showed clinical improvement in DH compared with the <5% group postintervention (-9.1 +/- 14.5% vs. -125 +/- 13.5%, respectively). In addition, the >= 5% group displayed a significant delay in the onset of both DH and EH, and a clinically significant improvement in HRQoL and asthma control. Furthermore, a correlation was observed between reduced waist circumference and increased inspiratory capacity (r = -0.45, P = 0.05) in the >= 5% group. In conclusion, a weight-loss of >= 5% of the body weight improves DH, which is associated with waist circumference in obese adults with asthma. In addition, the group with greater weight-loss showed a delayed onset of DH and EFL during exercise and improved asthma clinical control and HRQoL. NEW & NOTEWORTHY This is the first study to evaluate dynamic hyperinflation (DH) after a weight loss program in obese patients with asthma. Our results demonstrate that moderate weight loss can improve DH in obese patients with asthma that is associated with a decrease in abdominal fat. Moreover, a minimum of 5% in weight loss delays the onset of DH and expiratory flow limitation besides inducing a clinical improvement in asthma quality of life and clinical control.
