COVID-19 infection-associated coagulopathy and its association with adverse outcomes in Indian gravidas: a prospective analysis

Background Objective of the study was the determination of trends of coagulation parameters and association between pregnant women with COVID-19 infection with adverse outcomes.

Methods Design of the study was a prospective observational study. The study was conducted at the Maulana Azad Medical College and associated Lok Nayak Hospital, New Delhi. A total of 142 pregnant women with confirmed COVID-19 infection were recruited and studied prospectively between May 2020 and April 2021. Trends of coagulation parameters were compared in groups divided based on the adverse outcomes. 11 patients had adverse outcomes which included ICU admission or mortality. There were no adverse outcomes in the remaining 131 patients.

Results The comparison of trends of coagulation parameters in both groups was studied. D-dimer and INR values were significantly higher, while fibrinogen level was significantly lower in COVID-19 subjects with adverse maternal outcomes than in those in which adverse maternal outcomes were not present (p<0.05). No significant difference was observed in other coagulation parameters like APTT.

Conclusions Universal screening of coagulation parameters of all pregnant women with COVID-19 can be considered because of the association of adverse maternal outcomes with deranged D dimer and fibrinogen in our study.
