PURPOSE: Obstructive sleep apnea (OSA) and Chronic Obstructive Pulmonary Disease (COPD) are both important health concerns. Data concerning the occurrence of COPD in patients with OSA vary between 11% and 20% in Western countries. Neither the association between chronic obstructive pulmonary disease and obstructive sleep apnea and the consequences of each disorder alone and together have been characterized in an adult community setting in the Philippines . We aimed to study the prevalence of OSA symptoms among stable COPD patients and to determine its impact on their quality of life.
METHODS: Sixty one patients with stable COPD consulting at the Philippine General Hospital were included in the study. They were asked to answer a self-administered, validated questionnaire on OSA and on quality of life, using the Saint Luke’s Medical Center Obstructive Sleep Apnea Clinical Score, the Saint George’s Hospital Respiratory Questionnaire and the Epworth Sleepiness Scale.Data were analyzed using t test.
RESULTS: Eleven percent of the subjects were found to have OSA symptoms. Those patients with OSA symptoms have higher body mass index (BMI), greater neck circumference, and greater daytime sleepiness than those patients without OSA symptoms. There is a significant clinical difference in the quality of life scores of those COPD patients without OSA symptoms and those with OSA symptoms. COPD patients without OSA symptoms had better quality of life score.
CONCLUSION: We conclude that (1) there is a significant prevalence of OSA symptoms among stable COPD patients ; (2) COPD patients without OSA symptoms have better quality of life than those with OSA symptoms.
CLINICAL IMPLICATIONS: The prevalence of OSA symptoms among stable COPD patients is 11%,comparable to the prevalence of COPD in patients with OSA in Western Countries.As there is a high risk of developing hypercapnia, pulmonary arterial hypertension, cor pulmonale,hypertension, stroke, myocardial infarction, and diminished quality of life in patients with OSA and COPD, there is need for early diagnosis of the combination of both diseases.
