Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: All patients who realize a complete immunoallergologic tests investigations at the University Hospital of Grenoble.

Who may be able to join

  • Cases where a non-iatrogenic cause was finally identified

Who cannot join

  • For the estimation and comparison of the proportions, the patients who haven't carried out all their immunoallergologic tests investigations at the University Hospital of Grenoble are not included (this concerns patient who have realized only oral rechallenge test at hospital)
  • To realize the comparative analysis of allergic versus non-allergic hypersensitivity drug reaction : cases that are insufficiently documented on clinical, biological and / or chronological aspects are excluded. This concerns especially patients who realize immunoallergologic tests investigations after a skin reaction that occurred "in childhood".

About this study

Official title: Etude de Cohorte Des Patients Suivis en Allergologie au CHU de Grenoble : hypersensibilité Allergique et hypersensibilité Non Allergique

The creation of a database containing the medical data of patients followed in allergology at the University Hospital of Grenoble will permit to study allergic versus non-allergic hypersensitivity drug reaction as well as the risk of cross-reactions between medicinal drugs belonging to the same pharmacological class.

The main objectives of the study are to estimate and to compare the proportion of allergic hypersensitivity drug reaction and the proportion of non allergic hypersensitivity drug reaction, and to characterize these two types of hypersensitivity drug reaction on clinical, biological and chronological aspects.

In a second time, ancillary study will be conducted in order to :

  • identify drugs that potentially induced histamine-liberation in patients diagnosed with non allergic hypersensitivity drug reaction
  • investigate the risk of cross-reactions between drugs belonging to the same pharmacotherapeutic class in patients diagnosed with allergic hypersensitivity drug reaction.
Read the detailed description

This study is an observational cohort study conducted at University Hospital of Grenoble. It include retrospectively and prospectively the patients followed in the allergology department for the realization of immunoallergological test after suspicion of hypersensitivity drug reaction. The data are collected in a database from medical consultation reports that are systematically reported to the pharmacovigilance regional center. An anonymization number is assigned for each patient included in the study.The data collected include patient's personal and family medical history, a clinical, biological and chronological description of the hypersensitivity reaction, the results of the immunoallergologic skin tests as well as the final diagnosis.

What is being measured

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

  1. Allergic Versus Non Allergic Hypersensitivity Drug Reaction

    Conclusion of the immunoallergologic tests investigations :

    • allergic hypersensitivity drug reaction case are diagnosed when the skin tests are positive or the skin tests are negative but the oral rechallenge test is positive.
    • non allergic hypersensitivity drug reaction case are diagnosed when the skin tests are negative AND the oral rechallenge test is negative.

    Measured: Through study completion, an average of 5 years

Secondary outcomes (4)
  1. - To determine the proportion of drugs involved in in allergic hypersensitivity drug reaction for each pharmacotherapeutic class

    Immunoallergologic tests investigations that conclude to an allergic hypersensitivity drug reaction

    Measured: Through study completion, an average of 5 years

  2. immediate allergic hypersensitivity and delayed allergic hypersensitivity on clinical, biological and chronological aspects

    Conclusion of the immunoallergologic tests investigations :

    • immediate allergic hypersensitivity drug reaction case are diagnosed when the skin tests are positive at 20 minutes for Prick tests or IDR or the skin tests are negative but the oral rechallenge test is positive immediately.
    • delayed allergic hypersensitivity drug reaction case are diagnosed when the skin tests are positive at 24 or 48 hours for IDR or the skin tests are negative but the oral rechallenge test is positive in the days following the reintroduction of treatment.

    Measured: Through study completion, an average of 5 years

  3. To determine the proportion of drugs that potentially induced histamine-liberation in patients diagnosed with non allergic hypersensitivity drug reaction for each pharmacotherapeutic class

    Conclusion of the immunoallergologic tests investigations :

    • non allergic hypersensitivity drug reaction case are diagnosed when the skin tests are negative AND the oral rechallenge test is negative.

    Measured: Through study completion, an average of 5 years

  4. - Proportion of cross-reaction between drugs belonging to the same pharmacotherapeutic class in patients diagnosed with allergic hypersensitivity drug reaction.

    Conclusion of the immunoallergologic tests investigations :

    • Cross-reaction are diagnosed when the immunoallergologic test investigation is positive for medicinal products belonging to the same pharmacotherapeutic class as the responsible treatment of the skin reaction.

    Measured: ancillary study, Through study completion, an average of 5 years

Are results available for this study?

The study was stopped early (reason given: departure of the investigator from the CHU Grenoble Alpes). Results are not available in the source record.

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?

Allergic Versus Non Allergic Hypersensitivity Drug Reaction (time frame: Through study completion, an average of 5 years). 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 NCT03369509, which also lists 3 linked publications.

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?
