title: [Immunoglobulin therapy in Gilles de la Tourette syndrome].
abstract: It has known for a long time that Sydenham's chorea and tics, as seen in Gilles de la Tourette's syndrome (GTS), are phenomenologically very similar. Tics may occur as symptoms of acute Sydenham's chorea or persist over years as residual symptoms. Investigating of children suffering from GTS, including obsessive-compulsive symptoms, have provided signs of a poststreptococcal autoimmune process but also shown that treatment based on immunological interventions has been effective. We treated a 14-year-old boy showing all diagnostic criteria of GTS, familial susceptibility, and an increase in the antibody titer of streptococcal antigens with 75 immunoglobulins i.v. over 5 days. Response to this therapy was good regarding motor tics, vocal tics, and behavioral symptoms such as disturbed impulse control which still persisted after 9 months. These findings and the successful therapy underline reports of the literature and point to a pathogenetic mechanism of an immunologically triggered disturbance of the striatal dopaminergic system, at least in a subgroup of GTS.
