Risk factors contributing in increased susceptibility and severity of COVID 19 infection during pregnancy. (Preprint)
BACKGROUND The corona virus disease 2019 (COVID-19) pandemic has spread globally and pregnant women are considerably prone to COVID 19 infection with increased maternal and perinatal complications. OBJECTIVE This study aims to explore the risk factors that contribute in susceptibility and severity of COVID 19 infection among pregnant women. METHODS A systematic search of articles relating to COVID 19 infection during pregnancy, was conducted, using PubMed, Scopus and Google scholar engine. RESULTS A total of 168 articles were initially identified. Seventy-seven papers were excluded for failing to address the aim of the study. After screening titles and abstracts, ninety-one full-text articles were retrieved for eligibility analysis. Seventeen studies addressed the susceptibility related to pregnancy, twenty-two studies evaluated the associated comorbidities, nineteen focused on immune system, thirty-five articles concentrated on the risk of coagulopathy and eleven addressed more than one risk factor. CONCLUSIONS Pregnancy, associated comorbidities, modulated immune response during pregnancy and risk of coagulopathy are considerable risk factors contributing in COVID 19 pathogenesis among pregnant women and may predict the outcome.
