目的:确定肾脏移植受者应用霉酚酸酯(MMF)的合理治疗窗浓度。方法选取110例肾移植受者分别于术后1月内、2~3个月、>4个月应用酶放大免疫分析技术测定口服MMF(分两次服用,间隔12 h)12 h后全血谷浓度(即MPA-C0),并观察受者用药期间急性排斥反应及药物毒副反应发生情况,对所有受者随访时间均为1年。结果统计资料显示,术后急性排斥反应发生率为13.64%(15/110),药物毒副反应发生率为32.73%(36/110),其中白细胞减少症12例,MMF相关性腹泻10例,感染10例,肝功能损害4例。发生急性排斥反应受者予甲基强的松龙冲击治疗后均成功逆转,药物毒副反应受者经治疗和(或)调整MMF剂量后病情恢复,无死亡病例及移植肾摘除病例。通过ROC曲线计算得出,MPA-C0控制在1.40~2.80 mg/L可较好避免肾移植术后急性排斥反应并减少受者的药物毒副反应。结论对肾移植术后服用MMF的受者进行MPA-C0监测,对MMF用量进行个体化调整,有利于预防急性排斥反应和药物毒副反应发生,减少并发症,提高移植肾及受者的存活率。
目的:確定腎髒移植受者應用黴酚痠酯(MMF)的閤理治療窗濃度。方法選取110例腎移植受者分彆于術後1月內、2~3箇月、>4箇月應用酶放大免疫分析技術測定口服MMF(分兩次服用,間隔12 h)12 h後全血穀濃度(即MPA-C0),併觀察受者用藥期間急性排斥反應及藥物毒副反應髮生情況,對所有受者隨訪時間均為1年。結果統計資料顯示,術後急性排斥反應髮生率為13.64%(15/110),藥物毒副反應髮生率為32.73%(36/110),其中白細胞減少癥12例,MMF相關性腹瀉10例,感染10例,肝功能損害4例。髮生急性排斥反應受者予甲基彊的鬆龍遲擊治療後均成功逆轉,藥物毒副反應受者經治療和(或)調整MMF劑量後病情恢複,無死亡病例及移植腎摘除病例。通過ROC麯線計算得齣,MPA-C0控製在1.40~2.80 mg/L可較好避免腎移植術後急性排斥反應併減少受者的藥物毒副反應。結論對腎移植術後服用MMF的受者進行MPA-C0鑑測,對MMF用量進行箇體化調整,有利于預防急性排斥反應和藥物毒副反應髮生,減少併髮癥,提高移植腎及受者的存活率。

Objective To determine the optimal dose range (therapeutic window) of mycophenolate mofetil (MMF) for preventing acute graft rejection following renal transplantation. Methods The trough concentration of MMF (MPA-C0) at 12 h after oral administration of the drug (two doses daily given at an interval of 12 h) was monitored in 110 renal transplant recipients within a month, in 2-3 months, and over 4 months after the transplantation using EMIT method. The occurrence of acute graft rejection and drug toxicity were observed in all the patients during the one-year follow-up. Results The incidence of acute graft rejection after transplantation was 13.64%(15/110) in these patients. Drug toxicity and complications occurred in 32.73%(36/110) of the patients, including 12 cases with reduced white blood cell counts, 10 with MMF cid-associated diarrhea, 10 with infection, 4 with liver function damage. Acute rejection was successfully reversed after methylprednisolone treatment and drug toxicity was managed by corresponding treatment and adjustment of MMF dose. No deaths or graft removal occurred in these patients. The ROC curve showed that a MPA-C0 of 1.40-2.80 mg/L was optimal in preventing acute rejection after the transplantation and reducing adverse drug effects. Conclusion Monitoring MPA-C0 and individualized MMF dosing help to prevent acute graft rejection, reducing drug toxicity and complications, and improving graft survival rate after renal transplantation.
