An observational study in Allergic Hypersensitivity Drug Reaction Versus Non-allergic Hypersensitivity Drug Reaction Cross Reaction, sponsored by University Hospital, Grenoble. Terminated at 1 site in France. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2019-02-06.
Sponsored by University Hospital, Grenoble · Observational
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 :
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.
All patients who realize a complete immunoallergologic tests investigations at the University Hospital of Grenoble.
Exclusion Criteria:
Patient followed in the allergology department for the realization of immunoallergological test after suspicion of hypersensitivity drug reaction.
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.
Time frame: Through study completion, an average of 5 years
- 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
Time frame: Through study completion, an average of 5 years
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.
Time frame: Through study completion, an average of 5 years
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.
Time frame: Through study completion, an average of 5 years
- 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.
Time frame: ancillary study, Through study completion, an average of 5 years
