摘要

简介：冯-威廉氏病（VWD）患者需要在围手术期注射冯-威廉因子（VWF）浓缩物。由于担心重复注射比例为 1:1 的 VWF/FVIII 凝血因子浓缩物（CFC）后会导致 FVIII 的蓄积，本研究对 FVIII 随时间推移的恢复和蓄积情况进行了探讨：这项单中心研究考察了接受围手术期 1:1 比例 CFC 输注的 VWD 患者。CFC 剂量根据体重和内源性 VWF/FVIII 活性而定。FVIII和VWF活性在T0（基线）、T1（输液后15分钟）和T2-T6（24-120小时）的谷值水平进行监测：我们纳入了 125 名患者，他们接受了 125 次手术（63 次大手术，62 次小手术），中位数为两次 CFC 输注（IQR 1-3）。CFC 的平均给药剂量为 35.7 IU/kg，FVIII 和 VWF 的恢复率分别为 2.6 IU/dL per IU/kg 和 2.4 IU/dL per IU/kg。T0 时的平均 FVIII 水平为 62（标清 51.9），T1：164（标清 80.4），T2：155（标清 62.8），T3：162（标清 59.8），T4：124（标清 78.4），T5：120（标清 65.3）IU/dL。T0 时的平均 VWF 活性水平为 29（标清 25.0），T1：133（标清 43.7），T2：92（标清 37.2），T3：86（标清 37.5）IU/dL。对输注三次以上的 47 名患者进行的亚组分析表明，平均 FVIII 水平没有累积：这项围手术期研究表明，1:1 比例的 VWF 产品对 VWD 患者的 FVIII 和 VWF 恢复效果极佳。反复输注后观察到稳定的 FVIII 和 VWF 活性水平，没有出现累积现象。大多数大手术只需输注三次 CFC。

Efficacy of a 1:1 ratio VWF/FVIII concentrate in patients with von Willebrand disease

Introduction

Patients with von Willebrand disease (VWD) require administration of von Willebrand factor (VWF) concentrates peri-operatively. Concerns about FVIII accumulation after repetitive injections of a 1:1 ratio VWF/FVIII clotting factor concentrate (CFC) led this study to explore the recovery and FVIII accumulation over time.

Methods

This monocentre study examined patients with VWD receiving perioperative 1:1 ratio CFC infusions. CFC dosing was based on body weight and endogenous VWF/FVIII activity. FVIII and VWF activity was monitored at T0 (baseline), T1 (15 min postinfusion), and trough levels at T2-T6 (24-120 h).

Results

We included 125 patients, undergoing 125 procedures (63 major surgeries, 62 minor), with a median of two CFC infusions (IQR 1–3). With a mean administered dose of 35.7 IU/kg CFC, recovery rates of FVIII and VWF were 2.6 IU/dL per IU/kg and 2.4 IU/dL per IU/kg, respectively. Mean FVIII levels at T0 were 62 (SD 51.9), T1: 164 (SD 80.4), T2: 155 (SD 62.8), T3: 162 (SD 59.8), T4: 124 (SD 78.4), and T5: 120 (SD 65.3) IU/dL. Mean VWF activity levels at T0 were 29 (SD 25.0), T1: 133 (SD 43.7), T2: 92 (SD 37.2), and T3: 86 (SD 37.5) IU/dL. Subgroup analysis in 47 patients with more than three infusions, showed no accumulation of mean FVIII levels.

Conclusion

This perioperative study demonstrated excellent FVIII and VWF recovery of a 1:1 ratio VWF product in patients with VWD. Stable FVIII and VWF activity levels were observed after repeated infusions, without accumulation. Most major surgeries required only three CFC infusions.
