ABSTRACT
Background: Recurrent pregnancy loss (RPL) is a serious problem on the women, it defined as two or more consecutive pregnancy losses before the fetus has reached birth. The aim of this study is to evaluate the association between the elevation in the factor VIII and RPL. Because women who have thrombophilia have increased risk of fetal loss in most studies.Methods: A total 72 women were recruited in this case control study. They divided into two groups: the RPL group included 41 women with a history of recurrent pregnancy loss and the control group included 31 healthy women, who had at least one successful pregnancy and none of them had a history of fetal loss or complicated pregnancy.Results: A majority of the patients of this study didn't have a high level of factor VIII, 9 of 41 (22%) patients of RPL group in comparison with 21 of 32 (65,6%) of control group, that suffer from the increase rate of FVIII, this means that factor VIII doesn't effect on RPL.Conclusions: The present study showed that the serum elevation in the factor VIII is not significantly associated with RPL.
ABSTRACT
Background: Implantation failure is determined when transferred embryos fail to implant following in vitro fertilization (IVF). In recent years, many studies suggest that implantation failure could be related to several genetic factors. In the current study, authors aimed to investigate the association of PKP3 rs10902158 (G>A) polymorphisms with the risk of implantation failure after ICSI treatment.Methods: 97 women, who underwent ICSI treatment owing to male factor infertility, were prospectively recruited in this cross-sectional study. Genomic DNA was prepared from peripheral blood samples in order to analyze the polymorphism (rs10902158) at the PKP3 gene by PCR-RFLP. The Results were presented as a genotype (GG, GA, and AA), and their relationship to IVF outcome was analyzed.Results: The patients were divided into two groups according to clinical pregnancy: the pregnant group included 51 patients (53%) and the non-pregnant group included 46 patients (47%). The clinical pregnancy outcome was significantly different between genotypes, which was 0%, 45.8% and 58.8% in the patients having the genotype AA, GA and GG respectively (p-value = 0.03).Conclusions: The presence of the allele A of the PKP3 SNP rs10902158 is associated with a reduced clinical pregnancy outcome in the patients undergoing ICSI treatment and may be helpful predictor for implantation failure.
