Effects of recombinant human interleukin 11 and granulocyte colony stimulating factor in mobilization for autologous peripheral blood stem cell transplantation / 中国实验血液学杂志

ABSTRACT

This study was aimed to evaluate the effects of recombinant human interleukin 11 (rhIL-11) and recombinant human granulocyte colony stimulating factor (rhG-CSF) in mobilization for autologous peripheral blood stem cell transplantation (APBSCT). 16 patients with non-Hodgkin's lymphoma or acute myeloblastic leukemia were given myelosuppressive chemotherapy, then were mobilized by using rhG-CSF 5 microg/(kg.d) for median 5.5 days and rhIL-11 50 microg/(kg.d) for median 4 days (experimental group) or rhG-CSF 5 microg/(kg.d) alone for median 5.5 days (control group). After mobilizing, the peripheral blood leucocyte and platelet counts, total mononuclear cells, CD34+ cells and CFU-GM counts in PBSC collection, and amount of apheresed platelet transfusion were assayed. The results showed that the peripheral blood leucocyte and platelet counts, total mononuclear cell, CD34+ cell and CFU-GM counts in PBSC collection were no significant difference between two groups (p>0.05). After APBSCT, the median time for neutrophil count>or=0.5x10(9)/L and the median time for platelet count>or=20x10(9)/L were 10.5 and 11.5 days in experimental group, while were 13 and 13 days in control group, respectively. The median amount of apheresed platelet transfusion was 3.5 unit in experimental group and 5 unit in control group. Data were significantly different between two groups (p<0.05). The adverse reactions of mobilization were mild fever, fatigue, symptoms like as common cold, poor appetite, dizziness, muscular soreness in experimental group, but only mild fever in control. These symptoms were well tolerated and overcome with drug withdrawal. It is concluded that the regimen of rhIL-11 in combination with rhG-CSF after myelosuppressive chemotherapy to mobilize PBSC is efficient and safe with rapid hematologic reconstitution and less platelet transfusions after APBSCT were used.
