Impact of continuous positive airway pressure therapy withdrawal in patients with obstructive sleep apnea: a randomized controlled trial.
Purpose: Continuous positive airway pressure (CPAP) is the gold standard for managing moderate-to-severe obstructive sleep apnea (OSA). However, adherence to CPAP usage remains problematic with many patients either intermittently or permanently discontinuing CPAP use. However, the impact of CPAP therapy discontinuation remains unclear. This study aimed to evaluate the effects of complete and intermittent CPAP withdrawal on clinical and objective relapse of OSA.
Patients and methods: This randomized study involved patients with moderate-to-severe OSA who were compliant with CPAP therapy. All subjects underwent a CPAP efficacy assessment (CPAP check), followed by 1 month of closely monitored CPAP usage. Subjects were then randomized into two groups: (1) complete CPAP withdrawal (NO-CPAP); (2) intermittent CPAP use (INT-CPAP) (using the device every other day). Clinical relapse was assessed daily and defined as reemergence of any of the OSA symptoms. Weekly home sleep testing was performed to assess OSA relapse objectively, defined as an apnea-hypopnea index (AHI) of > 5.
Results: A total of 22 patients were included, with 12 subjects assigned to NO-CPAP group and 10 to the INT-CPAP group. Both groups exhibited a rapid recurrence of OSA within 1 week of CPAP discontinuation, with significant increases in AHI, oxygen desaturation index, and time spent with O2 saturation < 90% compared to baseline CPAP-check parameters (p < 0.05). In addition, clinical relapse occurred earlier in ⁓70% of the INT-CPAP group (Median 2.9 days) and 33% in the NO-CPAP group (Median, 3.5 days) (p < 0.05). Age and neck circumference were identified as significant predictors of OSA relapse (p < 0.05).
Conclusion: Discontinuation of CPAP therapy, whether completely or intermittently, leads to rapid OSA relapse, with age and neck circumference being key predictors of OSA relapse. These findings underscore the impact of CPAP withdrawal and the need for continuous CPAP adherence to effectively manage OSA.

期刊介绍：
The journal Sleep and Breathing aims to reflect the state of the art in the international science and practice of sleep medicine. The journal is based on the recognition that management of sleep disorders requires a multi-disciplinary approach and diverse perspectives. The initial focus of Sleep and Breathing is on timely and original studies that collect, intervene, or otherwise inform all clinicians and scientists in medicine, dentistry and oral surgery, otolaryngology, and epidemiology on the management of the upper airway during sleep.
Furthermore, Sleep and Breathing endeavors to bring readers cutting edge information about all evolving aspects of common sleep disorders or disruptions, such as insomnia and shift work. The journal includes not only patient studies, but also studies that emphasize the principles of physiology and pathophysiology or illustrate potentially novel approaches to diagnosis and treatment. In addition, the journal features articles that describe patient-oriented and cost-benefit health outcomes research. Thus, with peer review by an international Editorial Board and prompt English-language publication, Sleep and Breathing provides rapid dissemination of clinical and clinically related scientific information. But it also does more: it is dedicated to making the most important developments in sleep disordered breathing easily accessible to clinicians who are treating sleep apnea by presenting well-chosen, well-written, and highly organized information that is useful for patient care.
