Plasma concentrations of vitamin K1 were similar in 37 patients with cystic fibrosis (median 46 ng/l) and 16 controls (49 ng/l). The plasma concentrations were lower than those previously described in adults, but higher than in neonates. There was no association between an increase in prothrombin time and vitamin K1 plasma concentration.
37例囊性纤维化患者的维生素K1血浆浓度(中位数为46纳克/升)与16名对照组患者(49纳克/升)相似。这些血浆浓度低于先前报道的成人水平,但高于新生儿。凝血酶原时间增加与维生素K1血浆浓度之间无关联。
