ABSTRACT
OBJECTIVE:
To explore the effect of anti-nuclear antibodies (ANAs) on the outcome of in vitro fertilization-embryo transplantation (IVF-ET) and to study the effect of ANAs in follicular fluid (FF) on embryonic development.METHODS:
The expression of ANAs in FF of patients treated with IVF-ET and healthy group. The patients were divided into ANAs-positive group and ANA-negative group. The age, duration of infertility, body mass index (BMI), basic follicle stimulating hormone (bFSH), anti-Mullerian hormone (AMH), number of retrieved oocytes, portion of metaphase II oocytes (MII), number of embryos in the cleavage stage, bipronuclear (2PN), number of embryos, number of high-quality embryos and the outcome of IVF-ET were compared between the two groups. In vitro, HTR8/SVneo trophoblast cells were cultivated and divided into ANAs-negative group (control group) and ANAs-positive group (ANAs-positive FF was added to cytotrophoblasts). The ANAs titer in the serum and FF of patients who treated with IVF-ET was detected using ELSIA method. CCK-8 assay and flow cytometry (at 24 h and at 48 h) were used to detect the cell proliferation and apoptosis frequency of the two groups, respectively.RESULTS:
Among those who underwent IVF-ET treatment, the number of retrieved oocytes, the number of fertilization and the portion of MII oocytes in the FF-positive group were significantly lower than those in the FF-negative group. Furthermore, the implantation rate and the clinical pregnancy rate were decreased, and early miscarriage rate was increased in the FF-positive patients than those in the FF-negative patients. In vitro, the cytotrophoblasts proliferation activity in the ANAs group was significantly lower than that in the control group. Moreover, the cytotrophoblasts apoptosis rate in the ANAs group was significantly higher than that in the control group.CONCLUSIONS:
Our data suggested that ANAs in FF might become an obstacle to embryonic development through promoting trophoblast apoptosis and inhibiting trophoblast proliferation. ANAs in FF might be an unfavorable factor for the outcome of those who undergo IVF-ET treatment.Palabras clave
