Procalcitonin is a predictor of disseminated intravascular coagulation in patients with fatal COVID-19

OBJECTIVE: The coagulopathies that present with COVID-19 are thrombotic microangiopathy and disseminated intravascular coagulopathy (DIC). Procalcitonin (PCT) levels have been shown to be significantly increased in COVID-19 patients in comparison with healthy subjects/asymptomatic coronavirus-positive patients. In this report, our aim was to assess the associations of the PCT level with DIC and the severity of COVID-19 infection. PATIENTS AND METHODS: In this cross-sectional, retrospective study, 71 consecutive patients with severe COVID-19 (21 with DIC and 50 without DIC) were enrolled in the study. The PCT level was obtained from hospital records. RESULTS: The PCT level was significantly higher in the patients with DIC than in those without DIC [1.9 (0.6-14.5) vs. 0.3 (0.2-0.4) (ng/mL), p<0.01]. The PCT level showed a positive and significant correlation with DIC (m0.382, p=0.001) and was an independent predictor of DIC in patients with severe COVID-19 (OR: 6.685, CI: 1.857-24.063. p<0.01). CONCLUSIONS: In summary, the PCT level was increased in severe COVID-19 patients with DIC compared with those without DIC. An increased PCT level might suggest the presence of DIC and may help in predicting COVID-19 severity.
