- Brief Summary
The syndrome of obstructive sleep apnea (OSA) is a common condition that affects 2-4% of the general population, causing an increase in sympathetic activity, changes in systemic blood pressure, and is associated with cardiovascular disease. The pathophysiological mechanisms that are altered as a result of the events associated with obstructive sleep apnea (hypoxia-reoxygenation, arousals and sleep fragmentation), are associated with an increased risk of developing erectile dysfunction in patients with Obstructive Sleep Apnea. Until today, the studies linking Erectile Dysfunction with Obstructive Sleep Apnea (OSA) are epidemiological studies.
The alterations in the expression profile of endothelial and cardiovascular dysfunction biomarkers and sex hormones disorders that are altered as a result of the events associated with OSA are associated to erectile dysfunction development.
Treatment with continuous positive airway pressure (CPAP) reverses the effects of OSA and patients with erectile dysfunction may improve erectile function.
The primary objective of the study is:
1. To evaluate the impact of CPAP treatment on erectile dysfunction in OSA patients.
The secondary objectives are:
1. To determine the profile of synthesis of different biomarkers related to endothelial dysfunction and cardiovascular disorder, which are altered as a result of the syndrome of obstructive sleep apnea and its relation to the risk of developing erectile dysfunction.
2. To compare the secretion profile of sex hormones related to control erectile function in a group of patients with syndrome of obstructive sleep apnea with and without erectile dysfunction.
3. To assess the prevalence of erectile dysfunction in patients with OSA.
4. To compare the psychological profile of patients with OSA with and without erectile dysfunction in order to detect psychological distress associated with the risk of developing erectile dysfunction.
5. To evaluate the impact of CPAP treatment on the secretion profile of sex hormones related to control erectile function in OSA patients.
6. To evaluate the impact of CPAP treatment on the psychological profile of patients with erectile disfunction in OSA patients.

Study & Design
- Study Type
- INTERVENTIONAL
- Study Design
- PARALLEL
- Arm && Interventions
Group Intervention Description OSA + ED + CPAP Continuous positive airway pressure OSA patients with erectile dysfunction diagnosis who are randomly allocated to receive CPAP.
- Primary Outcome Measures
Name Time Method Change in International Index Erectile Function (IIEF) score At baseline and 3 month Effect of 3-months CPAP treatment on the changes in the International Index Erectile Function score of patients with Erectile Dysfunction.
- Secondary Outcome Measures
Name Time Method Changes in Endothelial dysfunction biomarkers (ADMA, ICAM-1, VCAM-1, and VEGF) At baseline and 3 month Determine the profile of synthesis of different biomarkers related to endothelial dysfunction and cardiovascular disorder associated to obstructive sleep apnea and its relation to the risk of developing erectile dysfunction. Evaluate the impact of CPAP treatment on the changes in endothelial dysfunction biomarkers after 3 months. All markers measured in blood samples by means of Radioimmunoassay.
Changes in Sexual hormone profile (Testosterone, SHBG, free Testosterone, Prolactin, LH, and FSH) At baseline and 3 month Compare the secretion profile of sex hormones related to control erectile function in a group of patients with syndrome of obstructive sleep apnea with and without erectile dysfunction. Evaluate the impact of CPAP treatment on the change in the sexual hormone profile after 3 months. All hormones measured in blood samples by means of Radioimmunoassay.
Change in Self-Esteem And Relationship (SEAR) score At baseline and 3 month Compare the psychological profile of patients with OSA with and without erectile dysfunction in order to detect psychological distress associated with the risk of developing erectile dysfunction, using SEAR score. Evaluate the impact of CPAP treatment on the change in SEAR score after 3 months.
