Trial summary

Allergic rhinitis (AR) is defined as inflammation of the nasal mucosa after exposition to an allergen in sensitized patients. AR causes not only nasal symptoms such as sneezing, itchy nose, rhinorrhea and nasal obstruction, but also has a significant impact on quality of life. Read more about this study

About this study

Allergic rhinitis (AR) is defined as inflammation of the nasal mucosa after exposition to an allergen in sensitized patients. AR causes not only nasal symptoms such as sneezing, itchy nose, rhinorrhea and nasal obstruction, but also has a significant impact on quality of life. Symptom control and overall satisfaction in patients undergoing subcutaneous immunotherapy (SCIT) or sublingual immunotherapy (SLIT) on the long term has not yet been investigated so far.

control groupa control group of AR patients who visited the ear nose and throat (ENT) department of the University Hospitals Leuven in the same time period
patients having SCITpatients who started immunotherapy at the Department of Allergology of the University Hospitals Leuven between November 2007 and February 2010.

What is being measured

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

  1. Current Medication Use Three Years After Diagnosis of AR

    Percentage patients in both groups that still use medication for their allergic rhinitis symptoms, 3 years after starting their therapy (non IT-group vs IT-group)

    Measured: 3 years after starting SCIT

  2. Degree of Symptom Control 3 Years After IT or 3 Years After Medical Treatment With VAS of Total Nasal Symptom < 5/10 Defined as a Controlled Situation.

    Visual analogue scale (VAS) scores for TNS experienced during the last 4 weeks. Visual analog scales (VAS) have been used to rate the presence of symptoms or impairment of the daily activities. Patients had to answer each question by indicating a position with a vertical line between two endpoints, 0 cm for not bothersome versus 10 cm for extremely bothersome. In this way each question is scored between 0 and 10 points.

    Measured: 3 years after diagnosis

Secondary outcomes (2)
  1. Percentage of Patients Having Controlled Allergic Rhinosinusitis (AR) Symptoms 3 Years After Starting Treatment

    Based on the proposed cut-off value of VAS < 5/10 for total nasal symptoms (TNS), rhinitis was considered as being controlled in 69 IT patients (84%) versus 223 (63%) non-IT patients

    Measured: 3 years after starting SCIT

  2. Percentage of Patients That Met ARIA Criteria for Mild AR Symtoms at a Mean Interval of 3 Years After Diagnosis

    ARIA classification of AR is made by duration and severity of AR symptoms. Here are calculated the number of patients having mild acute rhinitis.

    Clinical practice guidelines such as the Allergic Rhinitis and its Impact on Asthma (ARIA) document focus on the quality of life as a principal consideration in assessment and treatment of AR

    Measured: 3 years after diagnosis

Where is the study taking place?

The record lists 2 sites 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?

Yes. Results are posted in the registry (first posted 17 Dec 2013). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Current Medication Use Three Years After Diagnosis of AR (time frame: 3 years after starting SCIT). The study lists 2 primary outcomes in all. 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 17 Dec 2013.
