title: [Plasmapheresis for macrophage activation syndrome and multiorgan failure as first presentation of juvenile dermatomyositis].
abstract: The use of extracorporeal techniques for the treatment of paediatric diseases has expanded dramatically in the past decade. Plasmapheresis, a technique for exchanging plasma components with albumin or plasma, has been used in some rheumatologic conditions. We report the clinical course of a 7 years old boy with clinical and biological features of macrophage activation syndrome and multiorgan failure, at the time of presentation of severe juvenile dermatomyositis, and non responsive to corticosteroids, cyclosporine and immunoglobulin. After 4 days in the paediatric intensive care unit, plasmapheresis was used as rescue therapy. Repeated therapeutic plasmapheresis was effective for improving the multiorgan failure and laboratory abnormalities. The patient was discharged on the 21st hospital day with good functional condition. Plasmapheresis should be considered as rescue treatment in patients with life threatening macrophage activation syndrome and systemic onset of juvenile dermatomyositis.
