Abstract

To illustrate the early alteration of plasminogen activator inhibitor-1 (PAI-1) in the recipients of hematopoietic stem cell transplantation (HSCT) and explore its clinical significance in transplantation-associated thrombotic complications. Ninety-five patients undergoing HSCT were enrolled in this study. PAI-1 level and other hemostatic parameters were measured by enzyme linked immunosorbent assay (ELISA) in platelet poor plasma samples from patients on conditioning therapy and then weekly until four weeks after HSCT. Significant increase in PAI-1 was detected after conditioning treatment, followed by a diminution in the very week on transplantation (week 0), then increased with in time after transplantation. According to the occurrence of transplant-associated complications, patients were classified into four groups: thrombus group \[veno-occlusive disease (VOD) (n = 5), thrombotic microangiopathy (TMA) n = 1\], aGVHD group (n = 29), infection group (n = 19) and non-complication group (n = 41). One of 30 patients (3.3%) was diagnosed as thrombus in the auto-HSCT group, while five of 65 patients (7.7%) did in the allo-HSCT group. PAI-1 level of thrombotic patients was significantly increased compared with non-thrombotic subje...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.

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.
