ABSTRACT
<p><b>OBJECTIVE</b>To explore the relationship between CMV reactivation and KIR haplotype or HLA-Cw genotype in patients after unrelated-donor hematopoietic stem cell transplantation (HSCT).</p><p><b>METHODS</b>From January 2003 to December 2008 the HLA-Cw/KIR genotype of 48 patient-donor pairs were determined by polymerase chain reaction with sequence specific primers (PCR-SSP) and sequence specific nucleotide (PCR-SSOP). Posttransplant CMV reactivation was performed by immune histochemically assay.</p><p><b>RESULTS</b>Of 48 patients, 15 were transplanted from unrelated donors with an antigen mismatch for HLA Cw and 33 patient-donor pairs were matched for HLA-Cw. The CMV reaction rate was 66.7% for HLA-Cw mismatch group and 48.5% for HLA-Cw match group (chi(2) = 1.39, P = 0.2375). Thirty-seven donor-patients pairs belonged to group C1 and 11 to group C2, and CMV reaction rate was 64.9% in group C1 and 18.2% in group C2 (chi(2) = 18.13, P < 0.0001). Twenty-six patients received graft from KIR haplotype A (group A donor) and 22 from KIR haplotype B donors (group B donor) and CMV reaction rate was 57.7% in group A donor and 50.0% in group B donor (chi(2) = 0.28, P = 0.5941). The number of donor activating KIRs (aKIRs) was less than that of recipient aKIRs in 34 patient-donor pairs in which the CMV reaction rate was 70.6%, and the number of donor aKIRs was more than that of recipient aKIRs in 14 patient-donor pairs in which the CMV reactivation was 14.3%. There was a significan difference between the two group (chi(2) = 12.44, P = 0.0004).</p><p><b>CONCLUSION</b>KIR and HLA-Cw genotypes influence the rate of CMV reactivation following non-T cell deleted unrelated donor hematopoietic cell transplantation.</p>
