Complications of successively double autologous hemopoietic stem cell transplants / 中国实验血液学杂志

ABSTRACT

In order to get clinical information about safety and feasibility of successively double autologous hemopoietic stem cell transplants (SD-AHSCT) in malignant hematological disease patients, the complications and hematological reconstitution after SD-AHSCT in 20 patients were analyzed retrospectively. 20 patients with hematologic malignancies received autologous peripheral blood stem/progenitor cell transplantation at the first transplant, and then were given autologous bone marrow transplantation as the second transplant at 4-10 months. The results showed that all the patients tolerated mobilization and collection of peripheral blood stem/progenitor cells as well as bone marrow collection. All the patients got enough hematological stem/progenitor cells for SD-AHSCT and achieved hematological reconstitution after SD-AHSCT. The speed of hematological reconstitution was positively correlated with the transfused quantity of hematological stem/progenitor cells (r = 0.968). The hematological reconstitution after the first autologous hemopoietic stem cell transplant (AHSCT) was earlier than that of the second (P < 0.05). There was no statistical difference between the first and the second AHSCT for the incidence of skin or mucous membrane bleeding (P > 0.05). No patients occurred massive hemorrhage during SD-AHSCT. The quantity of platelet transfusion in the second AHSCT was larger than that in the first AHSCT (P < 0.01). The incidence of oral ulcer in the first AHSCT was significantly higher than that in the second (P < 0.01). No statistical difference between the first and the second AHSCT was there in infectious sites, infectious pathogens and infection incidence (P > 0.10). All the complications were improved or cured, and no patients died of SD-AHSCT complications. In conclusion, SD-AHSCT is safe and feasible, and worthy to be further popularized.
