Abstract:
Objective To establish a convenient and specific molecular method for cytomegalovirus(CMV) surveillance in recipients of allogeneic hematopoietic stem cell transplantation(allo-HSCT) and ana-lyze the correlation between cytomegalovirus genotypes and transplant-related complication to decrease CMV-related mortality through restricted endoenzyme digestion.Methods 135blood samples were regularly col-lected from79consecutive patients who received allo-HSCT between April2001and April2003.Of the79 patients observed,median age was32(range from11to60) and the ratio of male and female was1.63∶1.DNA extracted from whole blood was amplified with CMV sequence using Nested PCR and gB genotypes were identified through restriction enzyme analysis.Results Among the135clinical isolates from79pa-tients,42cases(66specimens) were Positive.The gB genotype from42cases(45samples) were identified as gB1,21(46.7%);gB2,14(31.1%);gB3,7(15.6%);gB4,3(6.7%),respectively,by restric-tion enzyme analysis.Among them,3patients were successively infected with CMV gB1and gB2.The inci-dence of GVHD in groups of CMV(+) and CMV(-) was81.0% and32.4%,respectively(P
