Comparison with previous studies
Sentilhes [33] found no cases of thromboembolic disease or thrombocytopenia among 54 pregnant women with COVID-19 including five women who were admitted to ICU in Strasbourg. Guan [47] reported one case of DIC among 1099 cases of laboratory confirmed COVID-19 in non-pregnant patients of all ages (0.1% of cases). Tang [1] noted a higher incidence of coagulopathy in non-survivors which is in keeping with our findings. Whilst uncommon in pregnant women with COVID-19, our data suggests that the identification of haemostatic and coagulopathic changes may have value in the identification of women at risk of deterioration.
