Insights
This study found that D-Dimer levels, but not mean platelet volume (MPV), can help predict the risk of mortality in patients with COVID-19. Early D-Dimer assessment may aid in managing COVID-19 complications.
Area of Science:
- Medical research
- Hematology
- Infectious diseases
Background:
- COVID-19 is associated with thrombosis in both venous and arterial systems.
- Understanding thrombosis markers is crucial for managing COVID-19 and its complications.
- D-Dimer and mean platelet volume (MPV) are indicators related to thrombosis development.
Purpose of the Study:
- To investigate the potential of MPV and D-Dimer values in determining thrombosis risk and mortality in early-stage COVID-19.
- To analyze the association between hematological parameters and COVID-19 patient outcomes.
Main Methods:
- Retrospective analysis of 424 COVID-19 positive patients.
- Inclusion of demographic and clinical data, including hospitalization duration.
- Analysis of biochemical, hormonal, and hematological parameters, comparing living and deceased patient groups.
Main Results:
- White blood cells, neutrophils, and monocytes were significantly lower in the living group compared to the deceased group (p<0.001).
- No significant difference in MPV values was observed between survivors and deceased patients (p=0.994).
- D-Dimer levels were significantly higher in deceased patients (median 438 mg/L) than in survivors (median 0.63 mg/L) (p<0.001).
Conclusions:
- MPV levels did not show a significant relationship with mortality in COVID-19 patients.
- A significant association was observed between elevated D-Dimer levels and increased mortality risk in COVID-19 patients.
Objective:
COVID-19 may cause thrombosis in both venous and arterial systems. Familiarity with the signs and symptoms of thrombosis and its treatment is essential in treating COVID-19 infection and its complications. D-Dimer and mean platelet volume (MPV) are measurements related to the development of thrombosis. This study investigates whether MPV and D-Dimer values could be used to determine the risk of thrombosis and mortality in the COVID-19 early stages.
Patients And Methods:
424 patients who were COVID-19 positive, according to the World Health Organization (WHO) guidelines, were randomly and retrospectively included in the study. Demographic and clinical characteristics such as age, gender, and length of hospitalization were obtained from the digital records of participants. Participants were divided into living and deceased groups. The patients' biochemical, hormonal, and hematological parameters were analyzed retrospectively.
Results:
White blood cells (WBC), neutrophils, and monocytes were significantly different in the two groups (p-value <0.001), and their values were lower in the living group than in the deceased group. MPV median values did not differ according to prognosis (p-value = 0.994). While the median value was 9.9 in the survivors, it was 10 in the deceased. Creatinine, procalcitonin, ferritin, and the number of hospitalization days in living patients were significantly lower than in patients who died (p-value <0.001). Median values of D-dimer (mg/L) differ according to prognosis (p-value <0.001). While the median value was 0.63 in the survivors, it was found as 438 in the deceased.
Conclusions:
Our results did not show any significant relationship between the mortality of COVID-19 patients and their MPV levels. However, a significant association between D-Dimer and mortality in COVID-19 patients was observed.
