LOW LEVELS OF VITAMIN D WERE ASSOCIATED WITH COAGULOPATHY AMONG HOSPITALIZED CORONAVIRUS DISEASE-19 (COVID-19) PATIENTS: A SINGLE-CENTERED STUDY IN INDONESIA

Background: This study was aimed to explore the association of vitamin D in the risk of coagulopathy in coronavirus disease-19 (COVID-19). Methods: Clinical and laboratory findings were obtained from 50 confirmed COVID-19 patients hospitalized in Saiful Anwar General Hospital, Malang, Indonesia, from September to November 2020. Thrombotic events during hospitalization were recorded, and the ISTH disseminated intravascular coagulation (DIC) score was used to classify overt DIC. Hypovitaminosis D was defined by serum vitamin D level <49.92 nmol/L. Results: Among 50 patients, 42 (84%) had hypovitaminosis D, and 6 (12%) developed thrombotic events. Vitamin D levels were lower in patients with thrombotic events (p=0.015), D-dimer >2 mg/L (p=0.006), ISTH DIC score >= 5 (p=0.020), admitted on ICU (p=0.002), and non-survivor groups (p=0.007). Multivariate analysis for the risk in increased D-dimer levels showed low vitamin D as the only significant risk factor with OR 1.8 (1.2-4.4), p=0.034. Low vitamin D also increased the risk for developing overt DIC with OR. 5.4 (1.0-30.2), p=0.039. Vitamin D level had negative correlations with ferritin (R=-0.316, p=0.044) and CRP (R=-0.530, p=0.000). Conclusions: In conclusion, a low level of vitamin D was found in most hospitalized COVID-19 patients and might be associated with the development of coagulopathy.

Automated summary

The study found that most hospitalized COVID-19 patients have low levels of vitamin D, which may be associated with the development of coagulopathy.
