About this study

Acute cochleo-vestibular syndrome or labyrinthitis is characterized clinically by the sudden appearance of a great rotatory vertigo and a unilateral sensorineural hearing loss. In this clinical context, MRI is the examination to eliminate differential diagnoses and to make a positive diagnosis of labyrinthitis (supposedly infectious, immunologic or ischemic). The etiologies described are ischemic, infectious or autoimmune, so the risk factors are very variable (cardiovascular, autoimmune or infectious).

Labyrinthitis has been little studied as a clinical entity in its own right. Indeed, studies mainly focus on sudden deafness with subgroups of patients with vertigo.

Read more

The incidence of sudden deafness is of the order of 5 to 20 per 100,000 people per year but is probably under-diagnosed.

The individual and medico-economic consequences are similar to those of hearing loss, with an increased risk of dementia, depression, premature death and an increase in health care consumption.

Read the detailed description

The objective of the study is to evaluate the performance of MRI (sensitivity and specificity) to localize labyrinthine damage in the presence of an acute cochleovestibular syndrome (presumed to be infectious, ischemic or immunologic) compared to the reference paraclinical examinations for each of the structures.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To evaluate the performance of MRI (sensitivity and specificity) to localize labyrinthine damage in the presence of an acute cochleovestibular syndrome

    The evaluation criterion is the diagnostic performance (sensitivity/specificity) of MRI for each of the structures (basal turn of the cochlea/ 2nd turn of the spire/ 3 semicircular canals, utricle and saccule) in acute labyrinthitis compared to the complementary examinations (Audiogram, VNG, VHIT, cvEMP and VVS)

    Measured: Files analysed retrospectively from from January 01, 2014 to May 30, 2021 will be examined

Questions about this trial

What is this clinical trial studying?

An observational study of Vertigo Labyrinthine, run by University Hospital, Strasbourg, France at 1 site in France.

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 5 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 12 Dec 2023. 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 France. 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. 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?

To evaluate the performance of MRI (sensitivity and specificity) to localize labyrinthine damage in the presence of an acute cochleovestibular syndrome (time frame: Files analysed retrospectively from from January 01, 2014 to May 30, 2021 will be examined). 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 12 Dec 2023.
