OBJECTIVE: To evaluate the effect of high-dose intravenous immunoglobulin (IVIG) in toxic epidermal necrolysis (TEN), parameters that may affect response to treatment, and the effect of different IVIG batches on Fas-mediated cell death. DESIGN: Multicenter retrospective analysis of 48 consecutive TEN patients treated with IVIG. SETTING: Fourteen university hospital dermatology centers in Europe and the United States. PATIENTS: Forty-eight patients with TEN (skin detachment >10% of their body surface [mean, 44.8%; range, 10%-95%]). INTERVENTIONS: Infusion of IVIG in all patients (range, 0.8-5.8 g/kg), and analysis of the ability of different IVIG batches to inhibit Fas-mediated cell death. MAIN OUTCOME MEASURES: Objective response to IVIG treatment, final outcome at day 45, parameters that may affect response to IVIG treatment, and tolerance. RESULTS: Infusion of IVIG (mean total dose, 2.7 g/kg [range, 0.65-5.8 g/kg]; mean consecutive days, 4 [range, 1-5 days]) was associated with a rapid cessation (mean, 2.3 days [range, 1-6 days]) of skin and mucosal detachment in 43 patients (90%) and survival in 42 (88%). Patients who responded to IVIG had received treatment earlier in the course of disease and, on average, higher doses of IVIG. Furthermore, analysis of 35 IVIG batches revealed significant batch-to-batch variations in the capacity of IVIG to inhibit Fas-mediated cell death in vitro. CONCLUSIONS: Early infusion of high-dose IVIG is safe, well tolerated, and likely to be effective in improving the survival of patients with TEN. We recommend early treatment with IVIG at a total dose of 3 g/kg over 3 consecutive days (1 g/kg per day for 3 days).
