COPD in Obese Patients

Features of Chronic Obstructive Pulmonary Disease Clinical Course in Obese Patients

The study included 176 patients with COPD. The first group included 88 normal weight patients with COPD: 71 men and 17 women, mean age 62.40 ± 8.83 years. The second group included 88 patients with COPD and obesity: 64 men and 24 women, mean age 62.94 ± 5.96 years. We assessed the frequency of COPD exacerbations in last 12 months, the severity of symptoms such as dyspnea, sputum production, fatigue. Spirometry, six-minute walk test and analysis of body tissue type composition were performed. BODE index was calculated. Levels of leptin, adiponectin, interleukins-4,6,8,10, interferon-γ, c-reactive protein (CRP), tumor necrosis factor receptor 1 (TNF-R1), tumor necrosis factor receptor 2 (TNF-R2), tumor necrosis factor alpha (TNF-α) were measured in blood serum.
