After developing in pediatric hematology and nephrology, therapeutic apheresis is increasingly used in pediatric neurology despite a sparse level of evidence.
There are a few retrospective series with a small number of patients, concerning mainly autoimmune diseases (encephalitis, myasthenia gravis, polyradiculoneuritis).
The objective of this work is to study therapeutic apheresis (including plasma exchange and immunoadsorption) among french neuropediatric tertiary centers and to prove that this treatment modality is effective and well tolerated in pediatric neurology diseases.
