Abstract
Blood Cys concentrations were monitored twice weekly by RIA in nine patients undergoing renal transplantation. The Cys dose was adapted to obtain blood values between 100-400ng/ml. A negative correlation was found between plasma creatinine and blood Cys, even in those patients in whom the oral dosage was not changed (r = 0.65, n = 23, p less than 0.001). In vitro studies showed no effect of uraemic blood on Cys measurement. It seems probable that uraemia induces changes in distribution volume and/or gastrointestinal absorption of the drug. Careful monitoring of Cys during uraemia is therefore warranted.
对9例肾移植患者进行每周一两次的血Cys浓度监测。Cys剂量适用于100-400ng/ml的血药浓度。血浆肌酐与血Cys呈负相关,即使在口服剂量不变的患者中也是如此(r = 0.65, n = 23, p < 0.001)。体外研究表明,尿毒症血液对Cys测量没有影响。尿毒症似乎可能引起药物分布、体积和/或胃肠道吸收的改变。因此,有必要在尿毒症期间仔细监测Cys。
