Trial summary

Rhinitis, or inflammation of the nasal mucosa, can present with nasal obstruction, nasal discharge, itch or sneezing. If the sinusal mucosa is involved as well, it is called rhinosinusitis and facial pain or loss of smell is possible. Several causes are known, such as an underlying allergy ("allergic rhinitis", AR).

About this study

Official title: Prevalence of Nasal Hyperreactivity in Chronic Upper Airway Inflammation: a Prevalence Study

Rhinitis, or inflammation of the nasal mucosa, can present with nasal obstruction, nasal discharge, itch or sneezing. If the sinusal mucosa is involved as well, it is called rhinosinusitis and facial pain or loss of smell is possible. Several causes are known, such as an underlying allergy ("allergic rhinitis", AR). If at least 2 symptoms are present for at least 12 weeks, it is called "chronic rhinosinusitis" (CRS).

Up to 2/3 of the AR and CRS patients have symptoms upon exposure to triggers such as sudden temperature changes, smoke, fragrances… a phenomenon called "nasal hyperreactivity" (NHR). It is currently not clear why some patients suffer NHR while others do not.

In this study, the investigators want to determine the prevalence and severity of nasal hyperreactivity in patients with chronic upper airway inflammation. To this end, patients and healthy controls will be asked to fill out a questionnaire inquiring presence and severity of nasal symptoms upon exposure to particular environmental triggers.

What is being measured

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

  1. Comparison of the proportion of patients and healthy volunteers with nasal hyperreactivity

    Every participant will fill out a questionnaire inquiring presence of nasal symptoms evoked by environmental triggers and lasting longer than ten minutes (nasal hyperreactivity). The proportion of patients and healthy volunteers with nasal hyperreactivity will be compared.

    Measured: 3 months

Secondary outcomes (3)
  1. Comparison of nasal symptom severity in patients and healthy volunteers with and without nasal hyperreactivity.

    Every participant will fill out a questionnaire inquiring nasal symptom severity by means of a visual analogue scale (VAS). The severity of symptoms will be scored on a horizontal line of 10 cm, where 0 cm equals "no symptoms" and 10 cm equals "very severe symptoms". The VAS-scores of patients and healthy volunteers with and without nasal hyperreactivity will be compared.

    Measured: 3 months

  2. Comparison of the proportion of healthy volunteers and four groups of patients (allergic rhinitis, non-allergic non-infectious rhinitis, chronic rhinosinusitis with nasal polyps, chronic rhinosinusitis without nasal polyps) with nasal hyperreactivity.

    Every participant will fill out a questionnaire inquiring presence of nasal symptoms evoked by environmental triggers and lasting longer than ten minutes (nasal hyperreactivity). The proportion of healthy volunteers and four groups of patients (allergic rhinitis, non-allergic non-infectious rhinitis, chronic rhinosinusitis with nasal polyps, chronic rhinosinusitis without nasal polyps) with nasal hyperreactivity will be compared.

    Measured: 3 months

  3. Comparison of nasal symptom severity in healthy volunteers and four groups of patients [allergic rhinitis, non-allergic non-infectious rhinitis, chronic rhinosinusitis (CRS) with and CRS without nasal polyps] with and without nasal hyperreactivity.

    Every participant will fill out a questionnaire inquiring nasal symptom severity by means of a visual analogue scale (VAS). The severity of symptoms will be scored on a horizontal line of 10 cm, where 0 cm equals "no symptoms" and 10 cm equals "very severe symptoms". The VAS-scores of healthy volunteers and four groups of patients (allergic rhinitis, non-allergic non-infectious rhinitis, chronic rhinosinusitis with nasal polyps, chronic rhinosinusitis without nasal polyps) with and without nasal hyperreactivity will be compared.

    Measured: 3 months

Questions about this trial

What is this clinical trial studying?

An observational study of Hyperactivity and Chronic Rhinosinusitis (Diagnosis), run by Universitaire Ziekenhuizen KU Leuven at 1 site in Belgium.

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 6 inclusion and 3 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 Mar 2021. 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 Belgium. 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?

Comparison of the proportion of patients and healthy volunteers with nasal hyperreactivity (time frame: 3 months). 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 Mar 2021.
