977) with dispensing accuracy for each dosage strength group. Among Groups 1, 2 and 3, 23.0%, 44.9% and 73.4% of patients, respectively, had at least one single vial option dispensed selleck chemicals llc (P < 0.0001). A broader selection of rFVIII dosage strengths and more actual rFVIII potencies were associated with improved dispensing accuracy and more
single-vial users. This may translate into less waste, cost savings, increased convenience and improved adherence to physician-prescribed regimens. “
“Platelet function defects (PFD) are reported to occur frequently in adult women with heavy menstrual bleeding (HMB). Few studies on adolescent HMB report varying incidence rates (2–44%) for PFD. We reviewed our institutional experience in detecting and managing PFD in adolescent HMB.
Postmenarchial girls and adolescents with HMB seen at our institution undergo a comprehensive bleeding disorder work-up by paediatric haematology and paediatric gynaecology providers. Whole blood platelet aggregometry (WBPA) is performed as a second tier test after excluding thrombocytopaenia, coagulation factor PLX-4720 mouse deficiencies and Von Willebrand disease (VWD). We retrospectively reviewed the medical records of adolescents with HMB seen between June 2009 and November 2010, as approved by the Institutional Review Board. Patient demographics, clinical features, laboratory results, therapy details and patient outcome information were analysed. Overall, 114 postmenarchial girls and adolescents with HMB were evaluated; 68 patients (59%) had WBPA study performed. Nineteen patients (28%) had at least one aggregation or secretion click here defect; 12 (18%) had two or more such defects. Treatment included hormonal therapy (13/19; 68%), antifibrinolytic agents (8/19; 42%) and intra-nasal DDAVP
(3/19; 16%). Thirteen patients (81%) had improved outcome (median follow-up – 15.6 months; range of 1–66 months). In this study, PFD were identified in nearly one-third of girls with HMB, with the majority of these having two or more defects as identified by WBPA. Further prospective studies are needed to better define the prevalence and address appropriate management of HMB and other bleeding complications of PFD in adolescents. “
“Secondary factor VIII (FVIII) prophylaxis converts severe haemophiliacs (FVIII:C < 1 IU dL−1) to a moderate phenotype (FVIII:C ≥ 1 IU dL−1), however, plasma FVIII:C is a poor predictor of bleeding risk. This study used thromboelastography (TEG) and thrombin generation assay (TGA) to quantify coagulation across a 48 h rFVIII prophylaxis period. 10 severe haemophiliacs with varying clinical bleeding phenotypes received their standard rFVIII prophylaxis dose and blood samples were obtained over 48 h. Measured parameters included FVIII:C, TEG and TGA at each time point. FVIII:C pharmacokinetics (PK) and correlation between global assay parameters was performed. The FVIII:C PK parameters were consistent with previous literature.
