Abstract
MENDOZA-COUSSETTE, Ulises. D-dimer, ferritin and C-reactive protein. Value in the stratification of patients with COVID-19. Rev.Med.Electrón. [online]. 2024, vol.46 Epub June 07, 2024. ISSN 1684-1824.
Introduction:
The COVID-19 pandemic continues to challenge healthcare systems. The stratification of affected patients from biomarkers, a less invasive strategy, is still controversial.
Objective:
To check the discriminating capacity of ferritin, C-reactive protein and D-dimer in patients with moderate and severe COVID-19.
Methods:
A cross-sectional design was applied from June to November 2021. The qualitative variables and age were recorded by review of the patient’s clinical records. The determination of the aforementioned biomarkers was carried out at the time of inclusion in the study using the Roche reagents in the HITACHI Cobas C 311 analyzer. The SPSS statistical program was used for analyzing dates.
Results:
There was a predominance of hypertensive patients in both groups. Vaccination and female sex prevailed among the moderate ones, while men and chronic diseases among the severe ones. Higher levels of the three analyzed biomarkers were observed in the severe group (Mann-Whitney test p < 0.05). The association between these was significant in both groups (Spearman correlation, p < 0.05). 366 μg/L of ferritin; 36.25 mg/L of C- reactive protein and 1.02 μg/mL of D-dimer, acceptably distinguished between severe and moderate (area under the curve ˃ 0.5; p < 0.05).
Conclusions:
The presence of chronic comorbidities and unvaccinated individuals predominated among severe patients. A close correlation was shown between the biomarkers analyzed in both patient groups. Biomarkers showed discriminating capacity between moderate and severe COVID-19 disease.
