ABSTRACT Objective: To observe the curative effect and safety of dydrogesterone auxiliary active immunotherapy in treatment of recurrent miscarriage. Methods:76 cases of patients with recurrent spontaneous abortion were randomly divided into observation group and control group, each had 38 cases. Control group were treated with active immunotherapy treatment, observation group given dydrogestrone auxiliary active immunotherapy treatment, compared the progestational hormone(P), estradiol(E2), human chorionic gonadotropin(HCG) of the patients with 8 weeks and 9-12 weeks of gestation in two groups, and the success rate of miscarriage, abortion rates and birth defects rate.Also,the IFN-γ, IL-2,IL 4,IL-6,Th1, Th2, Th1/Th2 levels of survival fetus before and after treatmentand the adverse drug reaction would be compared.Results:The P, E2, HCG levels of pregnant patients with 9-12 weeks in the observation group were significantly higher than the control group and the same group of patients at 8 weeks (P<0.05). The success rate of miscarriage, abortion rates, and birth defects rates of the observation group were significantly better than the control group (P<0.05). After the treatment, the IFN-γ, IL-2, Th1/Th2 levels of obervation group were significantly lower than before, while the IL-4, IL-6 levels were significantly higher than before (P<0.05), for the control group, only IL-4, IL-6 levels were significantly higher than before (P<0.05).Compared the two groups, the IFN-γ, IL-2, Th1/Th2 levels of observation group after treatment were significantly lower than the control group, IL-4, IL-6 levels much higher than the control group (P<0.05). There was no statistically significant difference between the two groups about the adverse drug reaction rate (P>0.05). Conclusion:The dydrogesterone auxiliary active immunotherapy in treatment of recurrent miscarriage had good safety, it could enhance the curative effect, reduce the abortion rate, improve fetal survival rate, improve patient indicators, it was worth clinical promoting. |
