Title: Successful treatment of corticosteroid-dependent drug reaction with eosinophilia and systemic symptoms with cyclosporine. Author: Su HJ, Chen CB, Yeh TY, Chung WH. Journal: Ann Allergy Asthma Immunol; 2021 Dec; 127(6):674-681. PubMed ID: 34400311. Abstract: BACKGROUND: Drug reaction with eosinophilia and systemic symptoms (DRESS) is an intractable drug hypersensitivity disease with high mortality. The current standard treatment requires high-dose and long-term systemic corticosteroids, which may lead to adverse effects and intolerability of patients. OBJECTIVE: To evaluate the efficacy and safety of cyclosporine in patients with corticosteroid-dependent DRESS or intolerance to systemic corticosteroids. METHODS: A retrospective review of 8 patients with corticosteroid-dependent DRESS who were treated with cyclosporine as an alternative treatment owing to suboptimal response to regular doses of systemic corticosteroids for at least 3 weeks, flare-ups when tapering corticosteroids, or experiencing intolerable adverse effects of corticosteroids. RESULTS: In all 8 patients (4 women and 4 men; age range, 15-75 years), either intractable skin eruptions, persistent eosinophilia, or elevated liver function was noted after at least 3 weeks of treatment with systemic corticosteroids. The patients had marked cutaneous improvement and normalization of liver function and eosinophil count after adding cyclosporine, and the systemic corticosteroid treatment was smoothly tapered down. The mean dosage of cyclosporine was 1.68 ± 0.73 mg/kg/d, and the mean duration of cyclosporine treatment was 76.13 ± 35.64 days. Their serum eosinophil counts, serum alanine aminotransferase levels, and serum thymus and activation-regulated chemokine levels were all elevated at baseline and then significantly decreased during the recovery stage after cyclosporine therapy (P < .05). No adverse events were reported after adding cyclosporine. CONCLUSION: Cyclosporine is an effective and safe therapeutic alternative as a steroid-sparing agent for corticosteroid-dependent DRESS. Further prospective randomized controlled studies are required to confirm these preliminary results.[Abstract] [Full Text] [Related] [New Search]
