Analysis of dynamic disturbance in blood coagulation function of patients with Coronavirus Disease 2019 A retrospective observational study

Abstract

Coronavirus Disease 2019 (COVID-19) has became a major problem affecting global health security. To assess the differences and dynamic changes of blood coagulation function in COVID-19 patients with different severity. A total of 261 COVID-19 patients from January 24 to March 25, 2020 in Huangshi, Hubei Province were enrolled. We designed a retrospective observational study. Clinical information, including age, blood routine and blood coagulation function, were collected. According to the Diagnosis and Treatment Guidelines for COVID-19 (seventh version) that issued by the National Health Committee of the People’s Republic of China, patients were divided into 3 subgroups: 186 ordinary, 45 severe and 30 critical ones. We compared the differences in blood coagulation factors among groups. Average age in critical group (71.47 ± 11.48 years) was the oldest of 3 subgroups. At admission, statistically differences could be observed among ordinary, severe and critical patients in D-dimer (0.18 ± 0.33, 0.63 ± 1.13 and 1.16 ± 1.58 mg/L), fibrinogen/fibrin degradation products (FDP) (3.11 ± 5.30, 9.82 ± 23.91 and 21.94 ± 40.98 mg/ml), platelet [(169 ± 62.85), (188 ± 71.56) and (117 ± 38.31) × 109/L)] and lymphocyte count [(1.18 ± 0.46), (0.82 ± 0.35) and (0.75 ± 0.39) × 109/L)], respectively (P
