ABSTRACT
<p><b>OBJECTIVE</b>To investigate the alteration of microparticles (MP) in the recipients following hematopoietic stem cell transplantation (HSCT) and its significance, and to search the early diagnostic indicators of thrombotic complications after transplantation.</p><p><b>METHODS</b>According to the occurrence of transplantation-associated complications, 94 allo-HSCT patients were divided into 4 groups: thrombotic group (VOD n = 7, TMA n = 2), acute graft-versus-host disease (aGVHD) group (n = 27), infection group (n = 41) and non-complication group (n = 17). Alterations of serum concentration of tissue factor positive microparticles (TF(+) MP) and endothelial microparticles (EMP) were analyzed by flow cytometry during the process of conditioning treatment and the early stage after transplantation. The relation of these 2 kinds of MP with complications was analysed.</p><p><b>RESULTS</b>(1) The levels of TF(+) MP and EMP of patients undogoing allo-HSCT before conditioning treatment were obviously higher than those in normal controls, and showed some elevation during different times, but there was no significant statistical difference. Although the levels of TF(+) MP and EMP at the end of conditioning treatment were some higher than those before conditioning treatment, but there was no statistical difference between them. (2)The levels of TF(+) MP and EMP in thrombotic group were obviously higher than those in aGVHD group and infection group (P < 0.05). (3)The levels of TF(+) MP and EMP in thrombotic group at different times were significant differences from those in other groups (P < 0.05), and the levels of TF(+) MP and EMP were no significant difference from those in non-complication group.</p><p><b>CONCLUSION</b>The increase of the TF(+) MP and EMP levels may be associated with occurrence of thrombosis after transplantation, indicating occurrence of the thrombotic complications, like hepatic vein occulusive disease (HVOD). The dynamically monitoring levels of TF(+) MP and EMP contributes to early discovery of thrombotic complications.</p>
