使用改良形式的活化全血凝血时间来评价血友病患者血液对因子VIIa的反应。在一年的时间内,对个体的重复测定显示出每个个体的一致性和个体之间的显著差异。4名血友病患者与抑制剂给予低反应因子VIIa的测定和低或中度的临床反应因子VIIa治疗的特点。另外4名对因子VIIa治疗具有中度至良好临床反应性的患者在测定中显示出对因子VIIa的强烈反应。具有增强的膜亲和力的因子VIIa突变体显示出比野生型因子VIIa高10至13倍的活性。结果可能证明更大规模的研究,以确定该测定的效用,患者的反应性评价和设置因子VIIa治疗水平。
Summary A modified form of the activated whole blood clotting time was used to evaluate response of blood from hemophilia patients to factor VIIa. Repeated assays of individuals over a one-year period showed consistency for each individual and significant difference between individuals. Four hemophilia patients with inhibitors gave low response to factor VIIa in the assay and were characterized as low or moderate clinical responders to factor VIIa therapy. Another four patients with moderate to good clinical responsiveness to factor VIIa therapy showed a strong response to factor VIIa in the assay. A factor VIIa mutant with enhanced membrane affinity showed 10 to 13-fold higher activity than wild type factor VIIa. The results may justify larger studies to determine the utility of this assay for evaluation of patient responsiveness and to set factor VIIa therapy levels.
