Brief Summary:
Complete blood count parameters are routinely evaluated cost-effective markers in diagnosis and clinical follow-up of infectious diseases.There is increasing number of studies to report the course of COVID-19 in pregnancy. The current study aimed to elucidate the changes in hematologic parameters in response to SARS-CoV-2 infection and whether there was an increase in adverse perinatal outcomes such as increased neonatal intensive care unit admission and lower APGAR scores in pregnancies with COVID-19.

Condition or disease Intervention/treatment
Pregnancy, Infections in Covid19 Other: Clinical assessment

Detailed Description:
The objective of this study is to evaluate the relationship between Coronavirus Disease 2019 (COVID-19) in pregnancy and adverse perinatal outcomes. The secondary aim is to analyze the diagnostic value of hematologic parameters in COVID-19 complicated pregnancies.The current study is conducted in a high volume tertiary obstetrics center burdened by COVID-19 pandemics, in Turkey, between March 20 and July 25, 2020. The study included a pregnant women cohort who had been regularly followed up and delivered in our clinics. The cohort was divided into two groups to reveal the impact of COVID-19 on the complete blood count cell indices and unfavorable obstetric and early neonatal outcomes in pregnant women. The clinically confirmed diagnosis of COVID-19 cases were included in Study Group (n=39) the healthy pregnant women without COVID-19 were included in Control Group (n=69). The study achieved a power of 0.89 and 0.98 with a 5% level of significance.

Group/Cohort Intervention/treatment
Group 1 (Pregnants with COVID-19)
Study group included pregnant women with clinically confirmed COVID-19.
Other: Clinical assessment
Perinatal outcomes and diagnostic value of hematologic parameters were compared between pregnancies with and without COVID-19.

Group 2 (Pregnants without COVID-19)
Control group consisted of healthy pregnant women in the same number and same gestational week with the Study group.
Other: Clinical assessment
Perinatal outcomes and diagnostic value of hematologic parameters were compared between pregnancies with and without COVID-19.

Primary Outcome Measures :
  1. complete blood count parameters (including the number of lymphocytes, Leukocytes, monocytes, platelets and red blood cells). [ Time Frame: first 1 hour of hospitalization. ]
