ABSTRACT
OBJECTIVE:To study the optimal monitoring indexes of plasma concentration of cyclosporine A(CsA) in patients receiving hematopoietic stem cell transplantation.METHODS:The lowest CsA concentration(C0) and the highest CsA concentration(C2) in 23 hematopoietic stem cell transplant recipients were detected by FPIA.All the data were analyzed statistically.RESULTS:Within 6 months after hematopoietic stem cell transplanttion,C0,C2,C0+C2 and C2/C0 in the recipients were(228.84?142.48) ?g?L-1,(741.50?294.42) ?g?L-1,(970.34?391.18) ?g?L-1 and(3.88?1.94) ?g?L-1,respectively.CONCLUSION:As reasonable monitoring indexes for the plasma concentration of CsA,C0+C2 and C2/C0 can comprehensively reflect the exposure of drug in body and monitor the toxicity of CsA in liver and kidney.
