RESUMEN
Objective To investigate the clinical effect of active immunotherapy combined with endometrial local injury in women with recurrent spontaneous abortion( RSA) caused by negative-blocking antibodies.Methods 112 patients diagnosed RSA with negative -blocking antibodies were randomly divided into the treatment group (62 patients) and control group (50 patients).The patients in treatment group were treated by active immunotherapy combined with endometrial local injury.The patients in the control group were treated by active immunotherapy.The pregnancy outcomes were observed.Results The rate of pregnancy was 93.54%in treatment group,and 80.00%in the control group.The success pregnancy rate in the treatment group was significant higher than that in the control group (χ2 =4.65,P<0.05).The rate of abortion was 3.44% in the treatment group and 12.50% in the control group.It was significant lower than the control group(χ2 =4.90,P<0.05).After active immunotherapy,the pregnan-cy rate was 90.58%in positive-blocking antibodies group and 77.77%in negative-blocking antibodies group.The success pregnancy rate in positive-blocking antibodies group was significant higher than that in negative-blocking antibodies group (χ2 =4.27,P<0.05).The abortion rate in positive-blocking antibodies group was 2.60% and 19.05%in negative-blocking antibodies group.It was significant lower than that in negative-blocking antibodies group (χ2 =6.14,P<0.05).Conclusion It can significantly improve pregnant outcome and reduce the abortion rate with active immunotherapy combined with endometrial local injury in women with recurrent spontaneous abortion ( RSA) caused by negative-blocking antibodies.
RESUMEN
Objective To study the association between paternal CD3, CD4 and CD8 antigenecity to their pregnant spouses and the development of pregnancy induced hypertension (PIH). Methods Maternal serum from 15 women with PIH in the third trimester and 82 in normal pregnancies (16 in the first, 32 in the second and 34 in the third trimester) were incubated with paternal T lymphocytes. Monoclonal CD3, CD4 and CD8 fluorescent conjugated antibodies were then added and the percentage of paternal T cell differentiation antigen CD3, CD4 and CD8 were measured by flow cytometry. Results During normal pregnancy, the levels of maternal serum blocking antibodies on paternal CD3, CD4 and CD8 were (4.14?1.02, 2.02 ?0.24, 2.37?1.05)% in first trimester, (-0.29?0.13, 1.03?0.27, 0.65?0.23)% in the second trimester and (-1.33?1.47,0.15?0.01, -1.04? 0.37)% in the third trimester. There were significant difference between them( P
