Abstract

To explore the relationship between CMV reactivation and KIR haplotype or HLA-Cw genotype in patients after unrelated-donor hematopoietic stem cell transplantation (HSCT). 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. 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 whi...Continue Reading

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
