We analysed 255 frozen plasma samples from patients who were prescribed FVIII measurement including treated and untreated haemophilia A patients. Twenty-six runs were performed on a 28-week period, each including four lyophilized control and at most 10 patient plasma samples. In control samples, FVIII

activities were not significantly different when the assay was performed using the stored calibration curve or was daily calibrated. The same applied to FVIII activities in patient plasma samples that were not significantly Deforolimus datasheet different throughout the measuring range of activities [68.3% (<1–179) vs. 67.6% (<1–177), P = 0.48] and no relevant bias could be demonstrated when data were compared according to Bland and Altman. These results suggest that in the studied technical conditions, performing the FVIII assay using a stored calibration curve is reliable, for at least 6 months. Therefore, as far as the same lots of reagents are used, it is not mandatory to include a calibration curve each time the FVIII assay was performed. However, this strategy has to be validated if the assay is performed in different

technical conditions. “
“Summary.  The Group Medical Appointment (GMA) is a novel consultation form in which patients undergo individual consultations in each other’s presence. To compare participants’ experiences with GMA and Individual Medical Appointments (IMA), the usual standard of care, our team recently implemented the GMA for children aged 0–18 years with haemophilia or von Willebrand’s disease. Participants’ experiences KPT-330 price with GMA were measured using a standardized QUOTE-questionnaire. Of 100 addressed families, 53 participated in GMA. Of these 53 families, 38 parents (72%) and 14 adolescents (82%) filled in the questionnaire about the GMA. Patients not on prophylaxis were defined as less experienced and patients on prophylaxis, as experienced. Although parents were satisfied

with both GMA and IMA (median score 8.0 vs. 9.0 of 10), medchemexpress a significant difference was demonstrated between less experienced and experienced parents. After GMA, less experienced parents were significantly more satisfied (median score 8.0 vs. 5.0; P-value 0.006), felt more social support (82% vs. 30%; P-value 0.005) and reported additional learning effects with regard to disease and treatment (64% vs. 0%; P-value <0.001) than experienced parents. None of the less experienced parents reported privacy problems during GMA compared with 40% of experienced parents. In adolescents an identical trend was reported. Sixty-six per cent of parents would join a GMA in the future and 87% would recommend a GMA to others. The GMA is a valuable addition in haemophilia and von Willebrand care, especially for less experienced patients. It leads to improved satisfaction, social support and improved information. "
