Insights
Elderly patients with COVID-19 show a higher prevalence of hypercoagulable states, indicated by elevated D-dimer and fibrinogen levels. This coagulopathy is linked to increased systemic inflammation in older individuals.
Area of Science:
- Medical Research
- Hematology
- Infectious Diseases
Background:
- Clinical features of COVID-19 have been extensively studied.
- Coagulopathy in elderly COVID-19 patients remains underreported.
Purpose of the Study:
- To investigate coagulopathy in elderly COVID-19 patients.
- To compare coagulation parameters between elderly and younger COVID-19 patients.
Main Methods:
- Retrospective analysis of coagulation parameters in 189 COVID-19 patients.
- Patients categorized into older (≥65 years) and younger (<65 years) groups.
Main Results:
- Elderly patients exhibited significantly higher D-dimer and fibrinogen levels.
- Older COVID-19 patients showed a higher proportion of elevated fibrinogen and D-dimer.
- Coagulation parameters correlated positively with inflammatory markers like CRP and IL-6.
Conclusions:
- Elderly COVID-19 patients are more prone to hypercoagulable states.
- Coagulopathy in these patients is associated with excessive systemic inflammation.
Background:
Since the outbreak of coronavirus disease 2019 (COVID-19), clinical features have been analyzed in detail. However, coagulopathy in elderly COVID-19 patients has been scarcely reported.
Methods:
Coagulation parameters of 189 patients with COVID-19 in Tongji hospital were retrospectively analyzed among age groups.
Results:
Patients were divided into 2 groups: older group (≥65 years, n = 87) and younger group (<65 years, n = 102). The proportion of patients with elevated fibrinogen (79.0% vs 59.6%, p = .005) and D-dimer (78.0% vs 55.2%, p = .001) shows the significant difference between the groups. The elderly patients revealed significantly longer prothrombin time (14.0 [13.4-14.4]s vs 13.6 [13.2-14.1]s, p = .026), higher D-dimer (1.00 [0.5-1.9] μg/mL vs 0.6 [0.3-1.6] μg/mL, p = .013) and fibrinogen (5.2 [4.1-6.2] g/L vs 4.4 [3.4-5.7] g/L, p = .004) levels, compared to the younger group. A positive correlation was observed between the coagulation parameters and inflammatory markers including high-sensitivity C-reactive protein and interleukin-6 (p < .05).
Conclusions:
The hypercoagulable state is more common in elderly COVID-19 patients, and coagulopathy is associated with excessive systemic inflammation.
