    Abstract:
    Background: Drug reaction with eosinophilia and systemic symptoms (DRESS) is a rare drug reaction characterized by a skin rash, eosinophilia, and organ involvement. Objective: Our purpose is to focus on the clinical and epidemiological characteristics of DRESS in the elderly and to identify the incriminated drugs. Methods: This is a retrospective study including patients, hospitalized for DRESS with a RegiSCAR ≥4. The population was divided into 2 groups according to age: 65 years or older (G1) and <65 years (G2). The statistical study was performed using the comparative and multivariate analysis. Results: We included 55 patients (30.9% G1 and 69.1% G2). Skin manifestations were comparable in both groups. Lymphadenopathy was less common in G1 with a statistically significant difference (P = 0.012). Renal impairment was more frequent in the elderly with a statistically significant result (P = 0.005). DRESS in the elderly group was significantly associated with the occurrence of sepsis (P = 0.008). Allopurinol was the most common culprit associated with DRESS in G1 (P = 0.001). Relapses and recurrences were comparable in both groups (P = 0.71). Conclusions: DRESS in the elderly is associated with a high risk of complications, mainly kidney involvement and sepsis. Allopurinol is the most incriminated drug.
