About this study

Official title: Sleep-disordered Breathing in Postmenopausal Women and CPAP Treatment

The purpose of this study is to investigate the effectiveness of CPAP treatment to co-morbidities of sleep apnea by looking the change of the consumption of medication of the co-morbidities before and after starting the CPAP treatment.

Read the detailed description

Sleep-disordered breathing (SDB) is frequently linked with cardiovascular diseases including stroke and type 2 diabetes, which increase the indirect costs of sleep apnea. Also non-cardiovascular co-morbidities are possible but seldom studied. CPAP treatment reverses the increased healthcare utilization seen before the sleep apnea diagnosis.

Previous studies addressing the cardiovascular co-morbidities in SDB have focused on obstructive sleep apnea and in male populations, but not on partial upper airway obstruction. Partial upper airway obstruction is common in both genders but especially in women. According to investigators' clinical experience, women with partial upper airway obstruction are especially likely to have severe symptoms from their SDB. There are scarce data on cardiovascular co-morbidities associated with partial upper airway obstruction and the female gender.

To study the prevalence of co-morbidities adding to the burden of SDB (periodic obstructive breathing and partial upper airway obstruction), investigators applied a conservative but robust strategy using the governmental database of medication reimbursed by the public health insurance system. Investigators analyzed both the cardiovascular and non-cardiovascular co-morbidities in our clinical population of SDB, separately in patients with periodic obstructive breathing or with partial upper airway obstruction during sleep.Investigators found that concomitant diseases ware common in SDB. Asthma and/or COPD were surprisingly frequent, and also chronic hypertension had an increased prevalence. In addition, males had diabetes mellitus and females hypothyroidism more than general population. The results emphasize the importance of diagnosis and treatment of the co-morbidities such as asthma, COPD, hypertension, diabetes and thyroid insufficiency regardless if the patient has partial upper airway obstruction or obstructive sleep apnea.

Now, investigators hypothesize that CPAP treatment reduces the consumption of medication of the co-morbidities of sleep apnea. Therefore, a retrospective analyze of 5 year before and 5 year after starting the CPAP treatment the medication consumption of the same population previously used will be conducted. To do this, the governmental database of medication reimbursed by the public health insurance system will be used.

Questions about this trial

What is this clinical trial studying?

An observational study of Sleep Apnea, run by Turku University Hospital.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 9 May 2022. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in the consumption of medication of co-morbidities of sleep apnea (time frame: 5 year before CPAP treatment and 5 year after CPAP treatment). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 May 2022; AzTrials last refreshed its copy on 31 Oct 2026.
