ABSTRACT
Objective To investigate the clinical characteristics of the human Adenovirus (HAdv) infections in allogeneic hematopoietic stem cell transplantation ( allo-HSCT) patients and explore the clinical significance of HAdv monitoring .Methods A total of 845 cases underwent allo-HSCT were included retrospectively in Perking University People′s Hospital from October 2012 to August 2014.Peripheral blood HAdv load were monitored twice weekly within 100 days after allo-HSCT, or whenever necessary quantitatively by real-time PCR. Meanwhile, other clinical samples such as stool , urine, and bronchoalveolar lavage fluid ( BLAF ) were also detected qualitatively whenever necessary .The follow-up period was at least six months after allo-HSCT.All clinical data were collected and analyzed .Results The total positive rate of HAdv was 3.4% ( 29/845 ) .The incidence of HAdv infection was higher in children [3.8%(6/155), 2 ) clinically, 1 cases with pneumonia.There were 8 cases of death at the end of follow-up.Conclusions HAdv is an important pathogen causing infection in patients after allo-HSCT. The infenction is characterized with multiple organ involvement .CMV and EBV coinfection is common .HAdv monitoring was of great significance in allo-HSCT patients.
