AN OVERVIEW OF AUTOIMMUNITY IN IMPLANTATION FAILURE: A LITERATURE REVIEW

The aim: This review was aimed to understand the role of different types of autoantibodies like antiphospholipid, antithyroid, antisperm, antinuclear, anti-ovarian autoantibodies and heat shock protein HSP 60 in the process of implantation in the normal way of conceiving and IVF and also to estimate that how the presence of these autoantibodies affect the normal pregnancy outcome. Materials and methods: This review process performed in the obstetrics and gynaecology postgraduate department, Bogomolets national medical university, Kyiv, Ukraine. It was a review of already published papers not to need the ethical board committee's approval. By following the literature review guidelines, this paper was written and searched for relevant studies regarding autoantibodies and implantation, published in medical literature till 2020 were included in this review process. The search is done for studies published till 2020 in the English language from the Medline database, including Google Scholar, PubMed, Web of Science and Cochrane library database. Conclusions: Our recent work found that the involvement of APA, ANA and/or ATA in recipients of oocyte donations did not affect their pregnancy outcomes. Some researchers did not give any clear conclusion about these risks, and some stated that the use of some immunodepressant agents could be useful to reduce the harmful effects of these autoantibodies associated with implantation failure. Each autoantibody has a different mechanism of action to create the pathological state, some have direct effect, and some indirectly impact implantation. In future, further high-quality studies need to be performed for better understanding.
