Abstract:
Objective To discuss the clinical value of dynamic monitoring the copies of human cytomegalovirus(HCMV)-DNA in prophylaxis of HCMV pneumonia after renal transplantation.Methods There were 242 cadaveric renal transplantation recipients including 144 males and 98 females,with the average age of 41(from 17 to 71).They were divided into 2 groups(experimental group 127 cases,control group 115 cases).Recipients in experimental group were routinely monitored by blood preparation and urine aliquot FQ-PCR.The therapy was initiated when HCMC-DNA>1×103 copies/ml by blood preparation and/or urine aliquot FQ-PCR with intravenous ganciclovir for 4 weeks.The dosage was calculated according to creatinine clearance rate.FQ-PCR monitoring and Preemptive therapy was not performed in the control group.The pneumonia rate, death rate and survival between the two groups were compared. Results In experimental group, the HCMV pneumonia incidence rate was 6.3 % (8/127), onset time was 46-167 d, median time was 84 d, hospitalization time was 30-57 d,median time was 36 d, death rate was 12.5 % (1/8), breathing machine using rate was 12.5 % (1/8),concurrent other pathogen infection rate was 25 % (2/8), and + year renal graft survival rate was 98.4% (125/127).One was dead with graft function and the other dysfunction was because of acute rejection.In control group, the HCMV pneumonia incidence rate was 14.8%(17/115), onset time was 34-138 d,median time was 51 d, hospitalization time was 21-67 d,median time was 40 d,breathing machine using rate was 29.4% (5/17),concurrent other pathogen infection rate was 41.2%(7/17), death rate was 23.5% (4/17), and 1 year renal graft survival rate was 93.0% (107/115).Three was dead with graft function and the other one was dead of DGF.The other 4 cases of renal dysfunction were because of acute rejection.Significant difference existed between the 2 groups (P<0.05) except for hospitalization time (P> 0.05). Conclusion The preemptive therapy of CMV pneumonia after renal transplantation by dynamic monitoring the copies of HCMV-DNA in recipients could have a good effect, and the 1 year renal graft survival rate could be higher.
