目的 评估肾移植术后人巨细胞病毒(HCMV)感染的早期诊断和抢先治疗效果.方法 选择2007年1月至2009年1月进行肾移植手术并坚持随访的165例受者作为研究对象.移植术前及术后第2~8周每周1次、第9~24周每2周1次收集受者血液和尿液标本.采用实时荧光定量聚合酶链反应(FQ-PCR)方法检测血液和尿液标本中的HCMV DNA拷贝数.对浓缩尿中HCMV DNA超过103拷贝/ml的受者,立即给予更昔洛韦进行抢先治疗.结果 165例肾移植受者术前血液和浓缩尿中均未检测到HCMV DNA;从术后第2周开始,浓缩尿中就可检测到HCMVDNA,峰值出现在第6~8周,且同一检测时间点,浓缩尿中HCMV DNA阳性例数均明显多于血液中阳性例数.术后共有30例受者血液中检测到HCMV DNA,阳性率为18.18%;有64例受者浓缩尿中检测到HCMV DNA,阳性率为38.79%;浓缩尿中阳性率明显高于血液,差异有统计学意义(P<0.05).血液和浓缩尿中HCMVDNA均阳性的30例受者,经更昔洛韦抢先治疗后,病毒拷贝数逐渐下降,但有8例发展为巨细胞病毒性肺炎,经加强抗病毒以及其他综合治疗后痊愈,浓缩尿中HCMVDNA转阴时间为(10.2±3.4)d.另34例仅浓缩尿中HCMV DNA阳性的受者,经更昔洛韦抢先治疗后,无一例发展为巨细胞病毒性肺炎,浓缩尿中HCMV DNA转阴时间为(5.5±2.1)d,与血液和浓缩尿中HCMVDNA均阳性的受者比较,其转阴时间明显缩短,差异有统计学意义(P<0.05).结论 采用FQ-PCR方法检测受者的浓缩尿能提前检出HCMV DNA,提高阳性检出率.一旦受者浓缩尿中HCMV DNA阳性,采用抢先治疗效果较好.
目的 評估腎移植術後人巨細胞病毒(HCMV)感染的早期診斷和搶先治療效果.方法 選擇2007年1月至2009年1月進行腎移植手術併堅持隨訪的165例受者作為研究對象.移植術前及術後第2~8週每週1次、第9~24週每2週1次收集受者血液和尿液標本.採用實時熒光定量聚閤酶鏈反應(FQ-PCR)方法檢測血液和尿液標本中的HCMV DNA拷貝數.對濃縮尿中HCMV DNA超過103拷貝/ml的受者,立即給予更昔洛韋進行搶先治療.結果 165例腎移植受者術前血液和濃縮尿中均未檢測到HCMV DNA;從術後第2週開始,濃縮尿中就可檢測到HCMVDNA,峰值齣現在第6~8週,且同一檢測時間點,濃縮尿中HCMV DNA暘性例數均明顯多于血液中暘性例數.術後共有30例受者血液中檢測到HCMV DNA,暘性率為18.18%;有64例受者濃縮尿中檢測到HCMV DNA,暘性率為38.79%;濃縮尿中暘性率明顯高于血液,差異有統計學意義(P<0.05).血液和濃縮尿中HCMVDNA均暘性的30例受者,經更昔洛韋搶先治療後,病毒拷貝數逐漸下降,但有8例髮展為巨細胞病毒性肺炎,經加彊抗病毒以及其他綜閤治療後痊愈,濃縮尿中HCMVDNA轉陰時間為(10.2±3.4)d.另34例僅濃縮尿中HCMV DNA暘性的受者,經更昔洛韋搶先治療後,無一例髮展為巨細胞病毒性肺炎,濃縮尿中HCMV DNA轉陰時間為(5.5±2.1)d,與血液和濃縮尿中HCMVDNA均暘性的受者比較,其轉陰時間明顯縮短,差異有統計學意義(P<0.05).結論 採用FQ-PCR方法檢測受者的濃縮尿能提前檢齣HCMV DNA,提高暘性檢齣率.一旦受者濃縮尿中HCMV DNA暘性,採用搶先治療效果較好.

Objective To evaluate early diagnosis and preemptive therapy of human cytomegalovirus infection in renal transplant recipients. Methods We selected 165 renal transplant recipients who underwent transplantation from January 2007 to January 2009 and adhered to follow-up as research subjects. The samples of blood and urine were collected before transplantation, every 1 week from 2 to 8 weeks and every 2 weeks from 9 to 24 weeks after transplantation. The viral load of blood and urine was detected by fluorescence quantitative polymerase chain reaction (FQ-PCR). Once HCMV DNA load was more than 103 copies/ml, preemptive therapy was done immediately by ganciclovir. Results All the samples of blood and urine were negative before operation. HCMV DNA load could be detected in the concentrated urine at the second week and the peak of HCMV DNA loadoccurred from the sixth to eighth week after operation. At the same detection time, the number ofpositive recipients in the concentrated urine was more than in blood. In 30 cases HCMV DNA load was detected in the blood and the positive rate was 18.18%. In 64 cases HCMV DNA load was detected in the concentrated urine and the positive rate was 38.79%. The positive rate of the concentrated urine was significantly higher than in blood (P<0.05). In 30 cases positive for HCMV DNA in the blood and urine, ganciclovir was given and the viral load was decreased gradually. But 8 recipients developed into CMV pneumonia and were cured through the comprehensive treatment. The clearance time of HCMV DNA in the concentrated urine was 10.2 ± 3.4 days. Thirty-four cases that were only positive for HCMV DNA in the urine were also treated by ganciclovir and no case developed into CMV pneumonia. The clearance time of HCMV DNA was 5.5 ± 2.1 days, and the clearance time was shortened as compared with that in those positive for HCMV DNA in the blood and urine (P<0.05). Conclusion FQ-PCR can detect HCMV DNA in the concentrated urine in advance and increase the positive rate. Once the sample of the concentrated urine is positive, preemptive therapy has a good effect.
