SummaryWe have prospectively evaluated the biologic response to desmopressin (DDAVP) in 28 children with type 2 von Willebrand disease (VWD) in correlation with the phenotype and the molecular defect of VWF. The diagnosis of VWD type 2 was mainly based on VWF functional parameters and/or an aberrant VWF multimer pattern. Seventeen different mutations were identified (6 of them novel). No response with respect to the functional parameters VWF:RCo and/or VWF:CB was seen in patients with severe abnormality of the VWF multimer pattern. One patient with VWD type 2A phenotype IIC Miami did not respond with respect to VWF:CB, but showed a good response of VWF:Ag and FVIII:C as expected. Interestingly he showed a persistently high level of VWF:Ag and FVIII:C up to 4 hours after DDAVP infusion. Patients with minor alterations of multimer structure and particular mutations responded well to DDAVP, whereas patients with normal multimer structure but a defect in platelet dependent functional parameters did not respond with VWF:RCo. Conclusion: Children with VWD type 2 show a variable response to desmopressin depending on the mutation that correlates with the functional defect and the presence or absence as well as the half-life of large VWF multimers. Our data emphasize the usefulness of DDAVP testing even in patients with VWD type 2, possibly with the exception of VWD type 2B.

SummaryDesmopressin (DDAVP, Minirin® parenteral), which induces the release of von-Willebrand factor from endogenous stores, is indicated in von Willebrand disease type 1 (VWD 1). In the present study effectiveness of DDAVP was tested and side effects were recorded in patients with VWD 1, von Willebrand disease type 2 (VWD 2) or thrombocytopathy (TCP). Patients, methods Subjects were analysed prior to and after Minirin parenteral infusion (0.4 μg/kg body weight (b.w.) over 60 minutes) for partial thromboplastin time (PTT, seconds), ADP/epinephrine triggered plateletfunction analyzer (PFA-100) occlusion time (seconds), factor VIII activity (FVIII, %), VWF as ristocetin cofactor activity (VWF:RCo, %) and VWF antigen (VWF:Ag, %). Side effects of DDAVP during operative interventions were recorded per questionnaires by the patients. Results The mean ± standard deviation dose (n = 165 patients) of Minirin parenteral administered was 0.37 ± 0.02 μg/kg b.w., most often upcoming dental operations (57%) necessitated testing. Coagulation parameters of patients with VWD 1 or TCP normalised in almost all patients, but only in approximately 50% of patients with VWD 2 respectively. Appraisal of effectiveness of Minirin parenteral as good was 96% in case of VWD 1 and 95 % in case of TCP. During minor surgeries (n = 23) in 91% of the patients no complications and in 2 patients (9%) postoperative haemorrhages without need for further interventions occurred, but 83% of the patients reported adverse reactions in the questionnaires, although Minirin parenteral was well tolerated by all patients during DDAVP efficacy tests. Conclusion Desmopressin is well tolerated and affective in patients with VWD 1 and thrombocytopathy.
