Trial summary

It is anecdotally well known that patients snore more when their nose is blocked. However, the therapeutic effect of improving nasal airway patency on snoring indices remains a point of conjecture. Read more about this study

About this study

Official title: A Randomized Crossover Trial of the Effect of Nasal Steroids in Snoring Intensity

It is anecdotally well known that patients snore more when their nose is blocked. However, the therapeutic effect of improving nasal airway patency on snoring indices remains a point of conjecture. Indeed, Braver et al examined the effect of a nasal vasoconstrictor and failed to show any improvement in the number of snores after its application, although apnoea-hypopnoea index (AHI)seemed to decrease. Furthermore, Hoffstein et al documented that dilation of the anterior nares in patients without nasal pathology has a relatively weak effect on snoring, and routine use of nasal dilating appliances was not recommended for the treatment of snoring. In contrast to the aforementioned studies, intranasal corticosteroids have been shown to improve sleepiness and reduce AHI in patients with obstructive sleep apnea (OSA) implying that there might be an equivalent result for the use of nasal steroids on snoring indices.

Additionally, the present authors have demonstrated a strong correlation between apnoea-hypopnoea index and oral/oro-nasal breathing epochs in patients with OSA and normal nasal resistance and that nasal surgery is effective only in OSA patients who preoperatively have decreased nasal breathing epochs.

It is plausible thus to suggest that snoring severity, in equivalence to OSA severity, might be associated to oral/oro-nasal breathing epochs and that improving nasal patency by nasal steroids might also increase nasal breathing epochs and lead to decreased snoring indices in patients who had decreased nasal breathing before the administration of nasal steroids.

Patients will be randomized in two groups: the patients of the first group will undergo a one week therapy of nasal budesonide, then two weeks of washout period, and thereafter one week of nasal normal saline. The patients of the second group will undergo a one week therapy of nasal normal saline, then two weeks of washout period, and thereafter one week of nasal budesonide. Before and after each treatment regimen patients will undergo an assessment, which will consist of anterior rhinomanometry and polysomnography with concomitant measurement of snoring indices and breathing route pattern.

The investigators hypothesize that the application for one week of nasal budesonide has a beneficial effect on snoring indices in patients who present before the application decreased proportion of nasal breathing epochs and in whom nasal budesonide succeeded in increasing nasal breathing epochs.

Read the detailed description

Snoring intensity would be measured using a calibrated microphone-sound meter system. The 2 microphones will be suspended at a distance of 1 m approximately above the surface of the patient's bed. This arrangement allows a non-invasive measurement of snoring that simulates the distance between sleeping bed partners. Before every study the system would be acoustically calibrated using a reference noise produced by a noise generator (86 dB). The signal would be sent at a sampling rate of 12 KHz through an analogue-digital converter to a computer system for subsequent analysis. All digitized signals will be recorded in the hard disk of a personal computer. A noise analyzer (Praat; Boersma 2005) will be used for the intensity analysis of snoring sound (Boersma, 2005).

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing nasal spray Budesonide and Nasal spray Normal Saline in people with Snoring, run by Ioannis Koutsourelakis at 1 site in Greece.

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 5 inclusion and 2 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 16 Sep 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Greece. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

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

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

snoring intensity (time frame: one week therapy). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01849406, which also lists 1 linked publication.

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 16 Sep 2013.
