Effect of recombinant human interleukin 11 on recovery of platelets after peripheral blood hematopoietic stem cell transplantation / 中国实验血液学杂志

ABSTRACT

The aim of this study was to explore the effect of recombinant human interleukin 11 (rhIL-11) on platelet recovery after peripheral blood hematopoietic stem cell transplantation and its side-effects. 20 patients with hematologic malignancies treated by allogeneic peripheral blood stem cell transplantation (PBSCT) were randomly divided into test and control groups. The patients in test group were treated with rhIL-11 since the day 6 after PBSCT, while the patients in control group were given supporting treatment. The results showed that the average time of the platelet to recover to 20 x 10(9)/L was 22.8 days in test group and 27.3 days in control group (p < 0.01). The average time for platelet to recover to 50 x 10(9)/L was 25.7 days in test group, and 32.3 days in control group (p < 0.01). The average number of megakaryocytes was 15.6 in test group, and 7.8 in control group on day 30 after PBSCT (p < 0.01). In conclusion, the rhIL-11 is able to accelerate platelet recovery after peripheral blood hematopoietic stem cell transplantation.
