Immunomodulatory Treatment of Lyell's Syndrome: A Simultaneous Plasmapheresis and Intravenous Immunoglobulins Therapy

Abstract

Lyell's syndrome, or toxic epidermal necrolysis (TEN) is a rare but life-threatening condition. It manifests with blistering of skin and mucous due to subepidermal bullae and keratinocyte necrosis. In most cases, it is an immune response to drugs or their metabolites. The mortality in TEN is high despite optimal infection and wound control. There are no unequivocal treatment guidelines in TEN. Immunosuppressive treatment may increase the wound infection risk and mortality. The aim of the study was to evaluate a 10-year experience with immunomodulatory therapy in TEN. We perform a combination of plasmapheresis and intravenous immunoglobulins to control the disease. There were 35 patients in the group and we performed a post hoc evaluation. Twenty-eight patients received the full protocol and there were seven patients who did not complete the treatment (single therapy group). The mortality in the test group was 14.29%, and the difference reached statistical significance in comparison with the single therapy group (P < .05). Our protocol reduced the mortality risk five times. Our study proved that simultaneous plasmaphereses with intravenous immunoglobulins administration were safe and improved patients' outcome in TEN.
