摘要在 2 组纯合 PiZ 缺陷患者(治疗和未治疗)和 1 组健康志愿者中进行了 α1-抗胰蛋白酶 (ATT) 的药代动力学研究。 131I 标记蛋白的分布对应于 3 室模型。静脉注射的蛋白质迅速扩散到血管外室,在那里发生了一些滞留。 3组之间AAT代谢没有观察到显着差异。注射蛋白的半衰期略长于2.5天。 AAT 蛋白未保存。这些结果证实了临床试验期间收集的观察结果。也就是说,需要每周输注以获得稳定的血清 AAT 浓度。每月输注无法维持“平台”阶段。周期可能限于每两周一次。
SummaryA pharmacokinetic study of α1-antitrypsin (ATT) was performed in 2 groups of homozygous PiZ-deficient patients (treated and untreated) and 1 group of healthy volunteers. The distribution of the 131I-labelled protein corresponds to a 3-compartment model. The intravenously administered protein diffused quickly to the extravascular compartment where some retention occurred. No significant difference in AAT metabolism was observed between the 3 groups.The half-life of the injected protein is slightly longer than 2.5 days. The AAT protein was not stored. These results confirm the observations collected during the clinical trials. That is, a weekly infusion is necessary to obtain stable serum AAT concentrations. Monthly infusions are unable to maintain a ‘plateau’ phase. The periodicity may be limited to every 2 weeks.
