Abstract
Introduction
Catathrenia is a rare, idiopathic, sleep-related respiratory condition characterized by irregular groans, which occur during prolonged expiration in sleep. The origins of catathrenia remain inexplicable, the long-term prognosis unexplained. Moreover, empirical treatment with neither pharmacological nor non-pharmacological approaches was satisfactory.
Case report
We report a case of catathrenia with concurrent obstructive sleep apnea complicated with pulmonary hypertension and reviewed the literature.
Discussion
Treatment with nasal continuous positive airway pressure resulted in marked improvement of catathrenia, obstructive sleep apnea, daytime dyspnea, and pulmonary hypertension for our patient. We think that nasal continuous positive airway pressure can be an option for the treatment of this infrequent but sometimes very disturbing sleep disorder.
