Severe obstructive disease: Similarities and differences between smoker and non-smoker patients with COPD and/or bronchiectasis
Introduction: Poorly reversible airflow obstruction may or may not be related to smoking. Objectives: To describe patients with severe obstructive lung disease including etiology, imaging, functional aspects, systemic manifestations, and the pattern of bronchodilator response. Methods: Sixty-eight p...

Introduction: Poorly reversible airflow obstruction may or may not be related to smoking. Objectives: To describe patients with severe obstructive lung disease including etiology, imaging, functional aspects, systemic manifestations, and the pattern of bronchodilator response. Methods: Sixty-eight patients (age 55.9 ± 13.7 years, FEV1 [forced expiratory volume in one second] 31.9 ± 10.2% predicted) underwent spirometry, evaluation of body mass composition, 6-minute walk test, X-ray, thorax high-resolution CT scanning, and clinical evaluation. Results: Of 68 patients enrolled, 37 had chronic obstructive pulmonary disease (COPD) and 31, extensive bronchiectasis. Among COPD patients the CT scans showed emphysema in 78.4%, and bronchiectasis in 48.6%. There were no significant differences between smokers and non-smokers, except for vital capacity, significantly smaller in non-smokers (p < 0.001). We found 29 and 20 volume responders (VR) according to Paré et al. (FEV1/FVC > 1 = flow responder or <1 = VR) and ATS/ERS criteria, respectively. According to Paré et al. criteria, there were 18 patients with FEV1 < 30% predicted among 29 VR, and 12 with FEV1 < 30% predicted among 39 without volume response (p = 0.0101). Conclusions: In patients with severe obstruction, smoking does not appear to be relevant in determining functional or systemic differences, and Paré et al. criteria can detect more VR. Bronchiectasis is a common finding in severe COPD. Resumo: Introdução: A obstrução das vias respiratórias pouco reversÃvel pode ou não estar relacionada com o tabagismo. Objetivos: Descrever pacientes com doença pulmonar obstrutiva grave, incluindo etiologia, aspectos dos exames de imagem, parâmetros funcionais, manifestações sistémicas, e o padrão da resposta ao broncodilatador. Métodos: Sessenta e oito pacientes (idades de 55,9±13,7 anos, FEV1 [volume expiratório forçado num segundo] 31,9±10,2% previsto) foram submetidos a espirometria, avaliação da composição de massa corporal, teste de caminhada de 6 minutos, radiografia, tomografia computorizadas (TAC) de alta resolução do tórax, e avaliação clÃnica. Resultados: Dos 68 pacientes inscritos, 37 sofriam de doença pulmonar obstrutiva crónica (DPOC) e 31 de bronquiectasias extensa. Entre os pacientes com DPOC, as tomografias computadorizadas apresentaram enfisema em 78,4% e bronquietasias em 48,6%. Não existiram diferenças significativas entre os fumadores e os não-fumadores, exceto para a capacidade vital, significativamente inferior nos não-fumadores (p < 0,001). Encontramos 29 respondedores de volume (RV) pelos criterios de Paré et al. (VEF1/CVF > 1= respondedor de fluxo, se > 1 respondedor de volume), e 20 RV pelos criterios da ATS/ERS. De acordo com os critérios de Paré et al., existiam 18 pacientes com FEV1< 30% previsto entre os 29 RV, e 12 com FEV1 < 30% previsto entre os 39 sem resposta a uma prova de volume (p = 0,0101). Conclusões: Em pacientes com obstrução grave, o tabagismo não parece ser relevante na determinação de diferenças funcionais ou sistémicas, e os critérios de Paré et al. podem detetar mais RV. A bronquiectasias é uma descoberta comum em DPOC grave.
