    Objective: Smoking prevalence is frequently estimated on the basis of self-reported smoking status. That can lead to an underestimation of smoking rates. The aim of this study was to evaluate the difference between self-reported smoking status and that determined through the use of objective measures of smoking at a pulmonary outpatient clinic. Methods: This was a cross-sectional study involving 144 individuals: 51 asthma patients, 53 COPD patients, 20 current smokers, and 20 never-smokers. Smoking status was determined on the basis of self-reports obtained in interviews, as well as through tests of exhaled carbon monoxide (eCO) and urinary cotinine. Results: All of the asthma patients and COPD patients declared they were not current smokers. In the COPD and asthma patients, the median urinary cotinine concentration was 167 ng/mL (range, 2-5,348 ng/mL) and 47 ng/mL (range, 5-2,735 ng/mL), respectively (p < 0.0001), whereas the median eCO level was 8 ppm (range, 0-31 ppm) and 5 ppm (range, 2-45 ppm), respectively (p < 0.05). In 40 (38%) of the patients with asthma or COPD (n = 104), there was disagreement between the self-reported smoking status and that determined on the basis of the urinary cotinine concentration, a concentration > 200 ng/mL being considered indicative of current smoking. In 48 (46%) of those 104 patients, the self-reported non-smoking status was refuted by an eCO level > 6 ppm, which is also considered indicative of current smoking. In 30 (29%) of the patients with asthma or COPD, the urinary cotinine concentration and the eCO level both belied the patient claims of not being current smokers. Conclusions: Our findings suggest that high proportions of smoking pulmonary patients with lung disease falsely declare themselves to be nonsmokers. The accurate classification of smoking status is pivotal to the treatment of lung diseases. Objective measures of smoking could be helpful in improving clinical management and counseling.

    Effect of an Exercise Program on Lymphocyte Proliferative Responses of COPD Patients
    (2018) FERNANDES, Juliana Ruiz; SILVA, Cibele Cristine Berto Marques da; SILVA, Aline Grandi da; PINTO, Regina Maria de Carvalho; DUARTE, Alberto Jose da Silva; CARVALHO, Celso Ricardo; BENARD, Gil
    Exercise training has been shown to reduce symptoms and exacerbations in COPD patients; however, the exercise effect on patients' immune response is poorly known. We thus verified if an exercise program (EP) impacted on proliferative T cell response of COPD patients. Fourteen non-O-2 dependent COPD patients on standard treatment were studied. EP consisted in 24 sessions of aerobic and muscular training. Peripheral blood mononuclear cells were stimulated with the mitogen phytohemagglutinin and antigens from Haemophilus influenzae and cytomegalovirus, and the lymphocyte proliferative response (LPR) was assessed through the expression of Ki67 before and after the EP. The Quality of life [COPD assessment test (CAT)], dyspnea [(modified Medical Research Council scale (mMRC)], and 6-min walk distance were also assessed. The EP program increased significantly the LPR of TCD4+ lymphocytes to phytohemagglutinin and cytomegalovirus and H. influenzae antigens, but with TCD8+ lymphocytes the increase was less marked. Consistent with this, a higher proportion of TCD8+ than TCD4+ cells did not express the costimulatory molecule CD28. The EP also resulted in improvement of the quality of life, dyspnea, and physical capacity. The improvement in TCD4+ cell function may represent an additional mechanism through which the EP results in less exacerbations and hospitalizations.

    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, Alberto
    The 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.
