Abstract

To study the influence of cord blood total nucleated cell (TNC) dose on the efficacy of cord blood transplantation in children. Thirty-four children with hematological disease received cord blood transplantation. They were assigned to 3 groups according to the infused TNC dose: TNC>10 x 10(7)/kg (n=7), 10 x10(7)/kg>TNC> or =7 x 10(7)/kg (n=9) and TNC<7 x 10(7)/kg (n=18). The rates of graft and rejection of hematopoietic stem cells and the efficacy of transplantation were examined in the three groups. All 7 children in the group infused with TNC >10 x 10(7)/kg got a long-term stable engraftment. The median time of absolute neutrophil count >0.5 x 10(9)/L was 14.8 days (range 12-20 days) and platelets >50 x10(9)/L was 52.3 days (range 26-86 days). They survived in a disease-free state. Of the 9 children in the group infused with TNC between 10 x 10(7)/kg and 7 x 10(7)/kg, 7 got engraftment. The median time of absolute neutrophil count >0.5 x 10(9)/L was 16.4 days (range 11-30 days) and platelets >50 x 10(9)/L was 63.7 days (range 34-140 days). Four children got a long-term stable engraftment and survived in a disease-free state. Two children with beta-thalassemia major had secondary rejection after engraftment and autologous hema...Continue Reading

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.

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.
