Objective. To investigate the significance and prognostic value of risk factors for intrauterine fetal demise (IUFD) in women with complicated obstetric history (COH) who had COVID-19 in the second and third trimesters of pregnancy. Patients and methods. A retrospective study of 5027 medical records of pregnant women, postpartum women and neonates who received treatment in obstetric institutions in Almaty with positive PCR results for SARS-CoV-2 in the second and third trimesters of pregnancy was conducted. IUFD occurred in 46(0.9%) pregnant women. Results. The risk of IUFD increased with prolongation of COVID-19 treatment during pregnancy (OR =8.673, 95%CI: 4.25217.692), in the absence of therapy with low-molecular-weight heparin (OR=4.835, 95%Cl: 2.471-9. 459) and was also characteristic of moderate and severe COVID-19 (OR = 4.2667, 95% Cl: 1.0603-17.1689), with history of maternal anemia and acute respiratory viral infections (ARVI) (OR =3.524, 95% Cl: 1.643-7.559 and OR =4.117, 95% Cl: 1.881-9.010, respectively). Meanwhile, the absence of antibiotic and corticosteroid therapy was associated with a lower risk of IUFD (OR =0.415, 95%Cl: 0.184-0.937 and OR=0.278, 95%Cl:0.142-0.547, respectively) Conclusion. The risk of IUFD in pregnant women with COH and COVID-19 during pregnancy increased significantly with the duration of COVID-19 treatment, with moderate and severe course, and with the deficiency of anticoagulant therapy. At the same time, the absence of glucocorticosteroids and antibacterial agents showed a negative association with IUFD.
