Modern possibilities of correction of postcovid disorders in the fetoplacental complex

ABSTRACT

The objective: to determine the peculiarities of hormonal support, liver enzymatic function and the state of the fetal-placental complex (FPC) in unvaccinated women with fetal growth retardation (FGR) and placental dysfunction (PD) who was ill with the coronavirus disease during the current pregnancy, on the background of the proposed correction scheme of the disorders and evaluation of its effectiveness. Materials and methods. The study included 22 pregnant women with FGR and PD who were being treated and delivered in the Department of Pregnancy and Childbirth Pathology of the State Institution «Institute of Pediatrics, Obstetrics and Gynecology named after Academician O.M. Lukyanova National Academy of Sciences of Ukraine» in 2021–2022 and suffered a coronavirus disease during the current pregnancy. All pregnant women had a general clinical examination and the following parameters were additionally determined the level of placental lactogen (PL) in blood serum, indicators of liver enzyme activity (alanine aminotransferase – ALT, aspartate aminotransferase – AST, gamma-glutamyl transpeptidase – GHTP), the level of estriol in urine (after the 22d week of pregnancy). The examination was carried out before the start of treatment and preventive measures and 12–14 days after a 10-day course of therapy with simultaneous ultrasound (US) monitoring of the condition of the FPC. In the case of diagnosis of FGR and PD, a course of therapy was carried out, which included daily consecutive intravenous infusions of a balanced crystalloid infusion preparation with lactate and sorbitol in the amount of 200 ml and a solution of levocarnitine and arginine hydrochloride in the amount of 100 ml for 10 days, followed by ultrasound control of the condition of the fetus and FPC. The evaluation of the effectiveness of the treatment was carried out based on a combination of clinical, laboratory and instrumental indicators after 10 days of therapy. Results. All pregnant women had a moderate or mild course of the coronavirus disease at different terms of the current pregnancy. There were 9 (40.9 %) women who were infected with SARS-CoV-2 in the early terms of pregnancy (up to 12 weeks), and they were diagnosed the 2nd and 2nd-3rd degrees of FGR. The majority of pregnant women had gestational complications. Before treatment, 10 (45.5 %) women had oligohydramnios. FGR was diagnosed in 14 (63.6 %) pregnant women, among them in 3 (13.6 %) persons – fetal growth retardation of the 2nd-3rd degree, in 6 (27.3 %) – of the 2nd degree, in 5 (22.7 %) – 1st degree. The analysis of laboratory indicators demonstrated the increase in the levels of ALT, AST and GHTP, and a decrease in the levels of estriol in urine. After the proposed course of treatment, oligohydramnios was found only in 2 (9.1 %) women. The average amniotic index before treatment was 10.1, after treatment – 15.3. 4 (18.2 %) women were diagnosed FGR after the treatment. As a result of the treatment, the improvement of all determined laboratory parameters and perinatal consequences were determined. Conclusions. The proposed scheme for correcting the identified disorders with the inclusion of balanced crystalloid infusion preparation with lactate and sorbitol and balanced crystalloid infusion preparation with lactate and sorbitol drugs made possible to improve microcirculation, metabolic processes, and to normalize the consequences of postcovid endotheliitis in the vascular system of pregnant women in general and in the FPC, in particular. This was manifested in the improvement of clinical, laboratory and instrumental indicators of conducted studies and had a positive effect on perinatal results. © The Author(s) 2022 This is an open access article under the Creative Commons CC BY license.
