Management of pregnant women with COVID-19 infection should be conducted by a multidisciplinary team within the framework of an individualized patient approach for favorable outcomes.

The aim of this study is to share the comprehensive experience of a tertiary pandemic center on pregnant women with COVID-19 and to compare clinical outcomes between pregnancy trimesters. The present prospective cohort study consisted of pregnant women with COVID-19 who were followed up at Ankara City Hospital between March 11, 2020 and February 20, 2021. Clinical characteristics and perinatal outcomes were compared between the pregnancy trimesters. A total of 1416 pregnant women (1400 singletons and 16 twins) with COVID-19 were evaluated.Twenty-six (1.8%) patients were admitted to the intensive care unit (ICU) and maternal mortality was observed in six (0.4%) cases. Pregnancy complications were present in 227 (16.1%) cases and preterm labor was the most common one (n = 42, 2.9%). There were 311, 433, and 672 patients in the first, second, and third trimesters of pregnancy, respectively. Rates of mild and severe/critic COVID-19 were highest in the first and second trimesters, respectively. The hospitalization rate was highest in the third trimester. Pregnancy complications, maternal mortality, and NICU admission rates were similar between the groups. The course of the disease and obstetric outcomes may be different among pregnancy trimesters. A worse course of the disease may be observed even in pregnant women without any coexisting health problems.

Objective The aim of this study was to evaluate the maternal‐fetal Doppler patterns in pregnant women recovered from COVID‐19. Methods This prospective case–control study was conducted in Ankara City Hospital between July 1, 2020 and August 30, 2020. Thirty pregnant women who were diagnosed with COVID‐19 and completed the quarantine process were compared with 40 healthy pregnant women in terms of the fetal Doppler parameters. All pregnant women diagnosed with severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) infection were followed up in our clinic and their diagnoses have been confirmed in nasopharyngeal and oropharyngeal samples by quantitative real time reverse transcriptase polymerase chain reaction (RT‐PCR) method. Doppler ultrasonographic assessment of the uterine arteries (UtA) and middle cerebral artery (MCA) were used in addition to umbilical artery (UA) Doppler between 23 and 40 weeks of gestation. Also, cerebroplacental ratio (CPR) was calculated according to gestational age. Results The pulsatility and resistance indices of umbilical and UtA showed a significant increase in pregnant women in the study group compared to the control group ( p < 0.05). Multivariable logistic regression analysis revealed that pulsatility and resistance indices of the mean UtA were independently associated with disease (OR > 1000, 95%CI 9.77 to >1000, p = 0.009; OR 0,000 95%CI 0,000‐0,944, p = 0,049), respectively. Medical treatment was given to 16/30 (53%) of pregnant women diagnosed with COVID‐19. Conclusion In conclusion, uterine artery Doppler indices in the third trimester may have clinical value in pregnant women recovered from COVID‐19.

Introduction To evaluate the association of serum electrolytes with disease severity and obstetric complications in pregnant women with Coronavirus disease 2019 (COVID-19). Materials and Methods This prospective cohort study was conducted on pregnant women with confirmed COVID-19. Study population was divided into two groups: 1) Mild COVID-19 group (n = 811) and 2) Moderate/severe COVID-19 group (n = 52). Demographic features, clinical characteristics, obstetric complications, and serum electrolytes were compared between the groups. Afterward, a correlation analysis was performed to investigate the association between serum electrolyte disturbances with COVID-19 severity and obstetric complications. Results Highest serum sodium, hypernatremia, potassium replacement, hypopotassemia, hyperchloremia, initial serum magnesium, hypermagnesemia, and hypocalcemia were significantly higher in the moderate/severe COVID-19 group. The lowest serum sodium, lowest serum potassium, and initial serum calcium were significantly higher in the mild COVID-19 group (p < 0.05). Statistically significant positive weak correlations were found between hypernatremia, hypopotassemia, hyperchloremia, hypermagnesemia, hypocalcemia and COVID-19 severity (r values were 0.27, 0.20, 0.12, 0.18 and 0.12, p values were < 0.001, < 0.001, 0.02, 0.03 and 0.03, respectively). Furthermore, statistically significant positive weak correlations were found between hypopotassemia, hypochloremia, hypermagnesemia, and obstetric complications (r values were 0.10, 0.10, and 0.28, p values were 0.004, 0.03, and 0.001, respectively). A statistically significant negative weak correlation was found between hypomagnesemia and obstetric complications (r = − 0.23 and p = 0.01, respectively). Conclusion Electrolyte disturbances in pregnant women with COVID-19 seem to be associated with disease severity and obstetric complications.
