First results of the THROMKID study: A quality project for the registration of children und adolescents with hereditary platelet function defects in Germany, Austria, and Switzerland
Keywords: Hereditary thrombocytopathies, children, diagnostics
THROMKID is a quality project of the Paediatric Group of German Thrombosis and Haemostasis Research Society (GTH). Data from paediatric patients with hereditary thrombocytopathies (HT) treated in Germany, Austria, and Switzerland were obtained between May 2005 and August 2006. By evaluation of results of platelet function tests criteria were determined to assess the diagnosis in each patient into most likely, likely or unlikely. A total of 215 patients treated in 31 centers were identified. In 95 patients (44%) the diagnosis of HT was most likely, in 28 (13%) likely and in 92 (43%) unlikely. Taken the first two groups together (n = 123) the diagnoses were as follows: Glanzmann thrombasthenia (n = 39, 32%), Aspirin-like defect (n = 26, 21%), thrombocyte receptor defects (n = 21, 17%), storage pool disorders (n = 18, 15%), Bernard-Soulier syndrome (n = 10, 8%), Hermansky-Pudlak syndrome (n = 6, 5%) and MYH9-related hereditary makrothrombocytopenia (n = 3, 2%). The low prevalence of these diseases and the high percentage of patients with unclassified HT stresses the necessity for the establishment of a competence network for comprehensive care of these patients in the three German-speaking countries.
