摘要
目的评估心脏移植患者口服微乳化环孢素A(CsA)后2h时的血药浓度(C2)作为临床监测指标的安全性和准确性。方法107例心脏移植受者,除29例研究阶段移植的患者外,其余为定期随访患者。心脏移植术后口服微乳化CsA(以下“CsA”均指微乳化CsA)预防排斥反应,其中54例以服用CsA前即刻血药浓度(C0)为监测指标(C0组),另53例以C2为监测指标(C2组),所有患者入组时血肌酐(Cr)〈150μmol/L,丙氨酸转氨酶(ALT)〈80U/L。在测定血药浓度的同时,检查心脏及肝、肾功能。结果C0组和C2组肝损害发生率分别为25.0%(13/52)和10.0%(5/50);肾损害发生率分别为5.8%(3/52)和8.0%(4/50);急性排斥反应发生率分别为11.5%(6/52)和6.0%(3/50)。C0组中,未发生排斥反应者的C0为(0.131±0.074)μmol/L,低于发生排斥反应者的(0.133±0.078)μmol/L,但二者间的差异无统计学意义(P〉0.05);发生不良反应(肝、肾毒性)者的C0为(0.133±0.075)μmol/L,无不良反应者的C0为(0.131±0.073)μmol/L,二者间的差异无统计学意义(P〉0.05)。C2组中,未发生排斥反应者的C2为(0.659±0.296)μmol/L,高于发生排斥反应者的(0.516±0.217)μmol/L(P〈0.05);发生不良反应者的C2为(0.719±0.288)μmol/L,无不良反应者的C2为(0.579±0.271)μmol/L,后者明显低于前者(P〈0.05)。结论在提示急性排斥反应和CsA所致不良反应的准确性方面,C2均明显优于C0。
Objective To evaluate the safety and reliability of cyclosporine microemulsion (Neoral) C2 monitoring in Chinese heart transplant recipients, Methods 107 stable heart transplant recipients treated with Neoral, mycopherolate mofetil and steroids were randomly divided into two groups. Drug concentrations were supervised by different target levels in different groups. Blood chemistry parameters reflecting heart, liver and renal function were examined. Results The incidence of hepatoxicity in group G, and group C2 was 25.0% (13/52) and 10. 0% (5/50), and the nephrotc~ xicity rate was 5.8% (3/52) and 8. 0% (4/50), respectively. The acute rejection rate was 11.5% (6/52) in group C0 and 6. 0% (3/50) in group C2, respectively. The results of Neoral C0-C2 monitoring displayed that the difference was not statistically significant in C0 levels between rejection and nonrejection [(0. 133 ± 0. 078) μmol/L vs (0. 131 ± 0. 074) μmol/L] (P〉0. 05), while the difference in C2 levels was significant [(0. 516 ± 0. 217) /μmol/L vs (0. 659 ± 0. 296) μmol/L] (P(0. 05). There was also no statistically significant difference in G, levels between the recipients with side-effects and those without side-effects [(0. 133 ± 0. 075) μmol/L vs (0. 131 ± 0. 073) μmol/L] (P〉0. 05), but statistically significant difference was found in C2 levels [(0. 719 ± 0. 288) μmol/L vs (0. 579 ± 0. 271 ) μmol/L] (P〈0. 05). Conclusion Cyclosporine C2. monitoring is a more sensitive predictor not only for acute rejection but also for side-effects in stable Chinese heart transplant recipients.
