Brief Summary:

Background : Non steroidal anti-inflammatory drugs are responsible for 25% of reported adverse drug events which include immunological and non-immunological hypersensitivity reactions. NSAIDs have been reported to be the second most common cause of drug-induced hypersensitivity reaction (DHR). They are almost mandatory in a human life and therefore, the drug allergy work-up goes up until a DPT in order to confirm or rule out the diagnosis.

Objective: Detect eliciting dose thresholds during NSAIDs DPT in order to suggest optimal step doses and to describe subgroups at higher risk during the DPT

Methods:This retrospective study, using the survival analysis, comprised all patients who attended the allergy service of the UH of Montpellier from 1997 till 2017 with a clinical history related to NSAIDs DHR, who underwent NDAIDs DPT that turned positive and who gave their consent to be included in the study . The Patients are selected from the Drug Allergy & Hypersensitivity Database (DAHD).

Condition or disease
Drug Hypersensitivity

Detailed Description:

DHRs to NSAIDs may be induced by both specific immunological mechanisms and mechanisms not based on immunological recognition (cross-hypersensitivity reactions [CRs]) .They are almost mandatory in a human life and therefore, the drug allergy work-up goes up until a DPT in order to confirm or rule out the diagnosis. Although the overall prevalence of NSAID hypersensitivity has been reported between 0.6 and 7% of the general population .

The NSAIDs‐induced hypersensitivity reactions involve different mechanisms and present a wide range of clinical manifestations from anaphylaxis or severe bronchospasm developing within minutes after drug ingestion to non-immediate responses appearing after days and weeks This data-driven approach in designing the DPT protocol is the second step in improving DPT standardization, after BL antibiotics.

Primary Outcome Measures :
  1. Detect eliciting dose thresholds during NSAIDs DPT optimal step doses [ Time Frame: 1 day ]
    The DPT was considered positive if objective signs occurred during NSAIDs administration. The reactive dose (RD) was calculated from the total cumulative dose (mg) reached when the DPT was considered positive

Secondary Outcome Measures :
  1. Describe subgroups at higher risk during the DPT [ Time Frame: 1 day ]
    Identifying the independent variables (predictive factors), using the multivariate linear regression method, that remains significantly associated with a positive NSAIDs DPT
