Abstract:

BACKGROUND: There are many reports addressing the good effect of active immunotherapy on repeated miscarriage, but the effect of active immunotherapy on repeated implantation failure needs to be confirmed by further studies.
OBJECTIVE: To study the effect of active immunotherapy with lymphocytes on repeated implantation failure in in vitro fertilization-embryo transfer.
METHODS: Active immunotherapy with lymphocytes was done in 52 repeated implantation failure patients lacking blocking antibodies. Repeated implantation failure patients were divided into two groups: study group (74 cycles): active immunotherapy was done and blocking antibodies turned positive before embryo transfer; control group (92 cycles): active immunotherapy was not done before embryo transfer. The pregnancy outcome was compared between two groups.
RESULTS AND CONCLUSION: After the active immunotherapy with lymphocytes, the positive rate of blocking antibodies was 92% in repeated implantation failure patients. The pregnancy rate and implantation rate of study group were significantly higher than those of the control group (P < 0.05), but there was no significant difference in the miscarriage rate between two groups (P > 0.05). So the active immunotherapy with lymphocytes in repeated implantation failure patients may be helpful to improve the rate of pregnancy in following embryo transfer.
