Publication Accès libre Metabolic and inflammatory profile in obese patients with chronic obstructive pulmonary disease(Arnold, 2008-02-01) Drapeau, Vicky; Doucet, Mariève; Fournier, Guy; Tremblay, Angelo; Poulain, Magali; Poirier, Paul; Maltais, FrançoisBackground: Overweight and obesity have been associated with better survival in patients with chronic obstructive pulmonary disease (COPD). On the other hand, excess body weight is associated with abnormal metabolic and inflammatory profiles that define the metabolic syndrome and predispose to cardiovascular diseases. This study was undertaken to evaluate the impact of overweight and obesity on the prevalence of the metabolic syndrome and on the metabolic and inflammatory profiles in patients with COPD. Methods: Twenty-eight male patients with COPD were divided into an verweight/obese group [n 16, body mass index (BMI) 33.5 4.2 kg/m2] and normal weight group (n 12, BMI 21.1 2.6 kg/m2). Anthropometry, pulmonary function and body composition were assessed. The metabolic syndrome was diagnosed according to waist circumference, circulating levels of triglyceride and high-density lipoprotein cholesterol levels, fasting glycemia and blood pressure. C-reactive protein, tumor necrosis factor- (TNF-), interleukin-6 (IL-6), leptin and adiponectin plasma levels were measured. Results: Airflow obstruction was less severe in overweight/obese compared with normal weight patients (forced expiratory volume1: 51 19% versus 31 12% predicted, respectively, P 0.01). The metabolic syndrome was diagnosed in 50% of overweight/obese patients and in none of the normal weight patients. TNF-, IL-6 and leptin were significantly higher in overweight/obese patients whereas the adiponectin levels were reduced in the presence of excess weight. Conclusions: The metabolic syndrome was frequent in overweight/obese patients with COPD. Obesity in COPD was associated with a spectrum of metabolic and inflammatory abnormalities.Publication Restreint The effect of obesity on chronic respiratory diseases : pathophysiology and therapeutic strategies(Canadian Medical Association, 2006-04-25) Sériès, Frédéric; Drapeau, Vicky; Doucet, Mariève; Boulet, Louis-Philippe; Tremblay, Angelo; Poulain, Magali; Maltais, François; Major, Geneviève.Sedentary lifestyles and increased pollution brought about by industrialization pose major challenges to the prevention of both obesity and chronic respiratory diseases such as chronic obstructive pulmonary disease (COPD), asthma, obstructive sleep apnea and obesity hypoventilation syndrome. Obesity has emerged as an important risk factor for these respiratory diseases, and in many instances weight loss is associated with important symptomatic improvement. Moreover, obesity may influence the development and presentation of these diseases. In this article, we review the current understanding of the influence of obesity on chronic respiratory diseases and the clinical management of obesity concurrent with asthma, COPD, obstructive sleep apnea or obesity hypoventilation syndrome.
