The impact of the COVID-19 pandemic on the course of miscarriages.

Objectives: Miscarriage is the most common complication of pregnancy. Infections are well-known causes of pregnancy loss. It has been suggested that infection with SARS-CoV-2 virus may also have an adverse effect on the course of early pregnancy, causing miscarriage. Aim: To assess the impact of the COVID-19 pandemic on pregnancy loss during the first half of pregnancy. Material and methods: The clinical records of patients hospitalized at the Department of Fetal Medicine and Gynecology; Medical University of Lodz were retrospectively reviewed. The study was done during the pandemic (March 2020 to the end of March 2022) and the previous 2 years due to missed abortion, indicated by no fetal heartbeat and spontaneous (complete or incomplete) abortion with vaginal bleeding. Results: While 682 women were hospitalized due to miscarriage in the first half of pregnancy in the period 2018-2020, there were 516 hospitalized during the pandemic. No differences in the proportion of missed and spontaneous abortions with bleeding were found between the group of patients before and during the epidemic SARS CoV-2. COVID-19 exposure appears to have an impact on earlier pregnancy loss. Conclusions: There is no evidence that the COVID-19 pandemic predisposes to the abnormal course of pregnancy in its first half.
