title: [Follow-up study of human herpesvirus 6 and human cytomegalovirus infection in organ transplantation recipients].
abstract: OBJECTIVE
  To trace the study of the prevalence and adverse factors of human herpesvirus 6(HHV-6) and human cytomegalovirus(HCMV) infection in organ transplantation recipients.
  
  
  METHODS
  Blood and urine specimens were detected by virus isolation, polymerase chain reaction(PCR), and indirect immunofluorescent assay.
  
  
  RESULTS
  HCMV and HHV-6 isolation rate were 25.8% and 32.3%, respectively. Anti-HCMV IgM and anti-HHV-6 IgM positive rates before operation were 0% and 3.2%, their positive rates after operation were 19.4% and 25.8%, respectively. HCMV-DNA and HHV-6-DNA positive rates before operation were 35.5% and 45.2%; their positive rates after operation were 45.2% and 61.3%, and kept the high positive rates for a long period. The patients who died within 3 months were all complicated by HCMV and/or HHV-6 productive infection. The productive infection rates of HCMV and HHV-6 were 25.8% and 32.2%, respectively.
  
  
  CONCLUSIONS
  The majority of HCMV and HHV-6 infection are reactivation. Productive infection attack at 2 weeks after operation, reaches the peak at 3-4 weeks after operation, and attacks at anytime within 3 months. HCMV and/or HHV-6 productive infection are fatal to recipients.
