Erectile dysfunction in COPD patients

摘要

Sexual dysfunction is a common problem in chronic obstructive pulmonary disease (COPD). We aimed to assess the presence of erectile dysfunction (ED) in COPD patients. Ninety-three outpatients who had been diagnosed as COPD and followed in Bolvadin State Hospital, Afyon, Turkey, were included in the study. All patients underwent pulmonary function tests and arterial blood gas analysis. They completed International Physical Activity Questionnaire (IPAQ), Medical Research Council (MRC) Dyspnea Scale, Short Form 36-item Scale (SF-36), and International Index of Erectile Function (IIEF) Questionnaire. The mean age of 10 (10.8%) mild, 46 (49.5%) moderate, 28 (30.1%) severe, and 9 (9.7%) very severe COPD patients was 61.4 ± 9.8 years. Varying degrees of ED were detected in 67.7% of COPD patients. All patients with hypoxemia had ED. IPAQ score and all SF-36 parameters were low in patients with ED, while MRC score was high. Forced expiratory volume in one second, forced vital capacity, partial pressure of oxygen in blood, oxygen (O2) saturation, IPAQ score, and role-physical parameters were statistically low in ED patients (p = 0.04, 0.02, <0.01, <0.01, 0.02, and 0.04, respectively); MRC score was statistically higher in patients with ED (p = 0.02). Patients with moderate and severe ED had statistically lower score of mental health (p < 0.01 and p = 0.02, respectively). There was a positive correlation between IIEF score and IPAQ scores (p < 0.01), MRC scores (p = 0.01), general health (p < 0.01), role-physical (p < 0.01), role-emotional (p < 0.01), physical functioning (p < 0.01), and mental health (p < 0.01) parameters in SF-36. ED is frequently seen in COPD patients. Hypoxemia, smoking, and limitation of physical activity are thought to be associated with ED in COPD as mechanisms. Quality of life and the functional capacity are negatively affected with the presence of ED. It is important for a physician to question the sexual functions in patients with COPD. The presence of ED may be routinely considered in the daily practice of pulmonologists in COPD patients.
