“The goal of gene therapy for the hemophilias is to develop a product that can direct long-term expression of a clotting factor from a single administration. This has now been achieved in the setting of hemophilia

B, using an adeno-associated viral (AAV) vector expressing MK0683 nmr wild-type factor IX under the control of a liver-specific promoter. Use of an AAV8 capsid, with strong tropism for liver, allows intravenous infusion of vector, simplifying administration to an outpatient procedure. The human immune response presents obstacles to infusion of AAV vectors when administered through the circulation, but these are now understood well enough to allow successful management, through prescreening for anti-AAV antibodies to avoid a humoral immune barrier, and through use of a short course of steroids to dampen a T-cell-mediated immune response

to AAV capsid when indicated. Successful development of AAV-mediated, liver-directed gene transfer may add new treatment options for people with hemophilia. “
“Summary.  Desmopressin (DDAVP) is commonly used for treatment and prevention of bleeding complications in patients with bleeding disorders including haemophilia A, von Willebrand’s disease (VWD) and other less common disorders. Anti-infection Compound Library ic50 This article reviews the current evidence for the use of DDAVP in pregnancy to clarify its efficacy and safety with regard to maternal and foetal outcome. A search of the literature found 30 studies that reported DDAVP use in pregnancy for prophylaxis or treatment of bleeding complications with 216 pregnancies reported in total. The most common indication was prophylaxis for prevention of bleeding during pregnancy

and postpartum triclocarban haemorrhage. DDAVP was used successfully in the first and early second trimester for bleeding prophylaxis in 50 pregnancies. No postpartum bleeding complications were reported in 167 out of 172 pregnancies when DDAVP was used for peripartum haemostatic cover. Twenty-nine studies reported no significant adverse events as a result of treatment with DDAVP. One case of water intoxication seizure and one case of premature labour following the use of DDAVP was reported in a single study. Other maternal side effects included facial flushing and headache and were reported by one study. These side effects were generally well tolerated by patients. There were no other significant adverse events reported in any of the studies as a result of DDAVP use. Foetal outcome was recorded in ten studies with no adverse foetal outcomes.
