La désensibilisation Aux Venins d'hyménoptères : Quelle Est Son efficacité à Long Terme ? (EFLOTITA2)
Allergy to Hymenoptera venom is one of the main causes of anaphylaxis in adults, and is less common in the paediatric population. It can be severe or even fatal.
Despite the use of an emergency kit, including an adrenaline auto-injector (AAI), at present only hymenoptera venom immunotherapy (VIT) is effective in preventing subsequent severe systemic reactions.
Recurrence during the 5 years following cessation of VIT is about 10-15 percent. Studies evaluating longer-term efficacy are scarce.
At the University Hospital of Angers, hundreds of patients are treated each year, and its allergology unit has been providing VIT for over 15 years.
The purpose of this stufy is to evaluate VIT efficacy among patients who were treated with VIT and ceased VIT from 2005 to 2019, at the university hospital of Angers.

This is a monocentric and ambispective study. In the absence of opposition from the patient (within one month after the information letter was sent), the search for data of interest is carried out by consulting the participant's medical record. An investigator (doctor or intern) interviews the participant, or the legal guardian for minors, and performs a telephone survey.
Data are collected from the participants medical records. Information gathered are as follows : age, sexe, the date and symptoms following hyménoptera stings, the evolution of allergy skin testing, total and venom specific immunoglobuin E (IgE), venom specifc immunoglobulin G4 (IgG4), basophil activation tests (BAT) to hymenoptera venom, exposure to hymenoptera stings.
The telephone survey assesses potential new comorbidities and new treatments, exposure to hymeoptera stings, hymenoptera stings after VIT cessation, if known : the hymenoptera specy, the participants reaction to the sting, and the drug that has been used to treat the symptoms.
