“…Проведено Антифосфоліпідні антитіла належать до сімейства аутоантитіл, асоційованих з усклад неннями вагітності, у тому числі мертвонаро дженням та повторними викиднями [1,4]. Поширеність антифосфоліпідних антитіл у безплідних жінок коливається від 4% до 66% [5]. Таку розбіжність у різних джерелах можна пояснити відсутністю стандартизації аналізу, панеллю антитіл і популяцією пацієнтів.…”

Infertility is a unique pathology because it concerns a couple, not one person, and is the cause of a whole range of medical, social, demographic and economic problems. With the active development of assisted reproductive technologies, the demand for solving the problem of infertility has grown significantly. However, the prevalence of infertility remains stable, indicating many «white» spots in the diagnosis and treatment of this pathology and determining the search for new risk factors, diagnostic criteria, and treatment algorithms. Purpose — to analyze the factors that may affect implantation, namely the presence of lupus anticoagulant and antiphospholipid antibodies in women with infertility who have undergone in vitro fertilization. Materials and methods. A survey of 106 women diagnosed with infertility underwent treatment with assisted reproductive technologies in September 2019 — February 2021. The control (1) group consisted of women who received infertility treatment according to the standard scheme: controlled ovarian stimulation, gamete collection, intracytoplasmic sperm injection and embryo transfer. The main (2) group included patients who received aspirin, anticoagulants, and intravenous IgG immunoglobulins in addition to the standard treatment regimen. In the present study, levels of lupus anticoagulant and antiphospholipid antibodies were determined in both groups. Results. The study found no differences between groups of patients in levels of antibodies (AB) to phospholipids (IgG), beta-2-glycoprotein (IgG, IgM) and lupus anticoagulant (screening, confirmation) in the two groups of patients (p>0.05). Difference in two groups were in levels of AB to beta-2-glycoprotein IgM in controls, on average, 9.42 units/ml (5.86 units/ml — 12.35 units/ml), and in patients of main group — 7.23 units/ml (3.14 units/ml — 10.58 units/ml), p=0.015. One-factor logistic regression models were used to clinically understand the influence of factors associated with the risk of implantation failure. The analysis did not reveal a connection between risk of implantation failure and levels of autoantibodies (aAB) to phospholipids (IgG, IgM), beta-2-glycoprotein (IgG, IgM) and lupus anticoagulant (screening, confirmation) in two groups of patients (p>0.05 in all cases). Conclusions. The presence of aAB and/or antiphospholipid syndrome during the establishment of infertility factors is an essential component of the algorithm for diagnostic search for the cause of infertility and miscarriage. However, based on the obtained data, the presence of aAB in the study does not affect the implantation process nor affects the treatment of infertility. The research was carried out in accordance with the principles of the Helsinki declaration. The study protocol was approved by the Local Ethics Committee of the participating institution. The informed consent of the patient was obtained for conducting the studies. No conflict of interest was declared by the authors. Key words: infertility, implantation failure, antiphospholipid syndrome, assisted reproductive technologies.
