Utility of continuous positive airway pressure therapy for treating chronic coughs in patients with obstructive sleep apnea.
We experienced two patients with chronic coughs whose symptoms persisted after initial treatment under a diagnosis of suspected upper airway cough syndrome or cough variant asthma. Neither patient exhibited daytime somnolence, although both were subsequently found to have severe obstructive sleep apnea. Following the administration of nocturnal continuous positive airway pressure therapy, the cough symptoms rapidly improved in both cases. These cases represent the first reports of obstructive sleep apnea-induced chronic cough in Japan.
