Insights
COVID-19 infection significantly lowers serum lipid profiles, particularly high-density lipoprotein cholesterol (HDL-C). Lower HDL-C levels correlate with increased COVID-19 severity and inflammation markers.
Area of Science:
- Cardiology
- Infectious Diseases
- Biochemistry
Background:
- COVID-19 (Coronavirus Disease 2019) is a global pandemic.
- Understanding its impact on metabolic markers like serum lipids is crucial.
- This study investigates the serum lipid profiles of COVID-19 patients.
Purpose of the Study:
- To describe the serum lipid profile in patients with COVID-19 infection.
- To compare lipid profiles between COVID-19 patients and healthy controls.
- To assess the relationship between lipid profiles and COVID-19 severity.
Main Methods:
- Retrospective analysis of clinical laboratory data from 114 COVID-19 patients and 80 healthy controls.
- Monitoring of serum lipid profiles, viral nucleic acid, and chest CT scans in a severe COVID-19 case over 80 days.
- Correlation analysis between lipid parameters, inflammatory markers (CRP), and lymphocyte counts.
Main Results:
- COVID-19 patients exhibited significantly lower total cholesterol, HDL-cholesterol, and LDL-cholesterol compared to controls.
- Severe COVID-19 cases showed significantly lower HDL-cholesterol concentrations than common cases.
- A severe patient's HDL-cholesterol levels decreased early in infection and normalized during recovery, mirroring disease progression.
Conclusions:
- Reduced serum HDL-cholesterol is strongly associated with COVID-19 severity.
- HDL-cholesterol may serve as a potential biomarker for assessing COVID-19 disease progression and severity.
Background:
COVID-19 infection is epidemic worldwide. We describe the serum lipid profile of the patients with COVID-19 infection.
Methods:
In this retrospective study, we collected the first clinical laboratory data of 114 patients on admission, and 80 healthy controls. Meanwhile, we monitored the serum lipid profile, COVID-19 nucleic acid and chest CT scan of a severe patient from the early stage of infection to the recovery period for a total of 80 days.
Results:
Compared with the healthy controls, the patients had sharply decreased concentrations of total cholesterol, HDL-cholesterol and LDL-cholesterol (P < 0.001). Among the patients, HDL-cholesterol concentration in severe groups was significantly lower than the common groups [1.01 (0.88-1.20) vs 1.21 (1.02-1.48) mmol/l, P < 0.001]. The lipid profile of a severe patient showed that serum cholesterol concentration significantly decreased in the early stage and returned to be normal in the recovery period. Moreover, the change of HDL-cholesterol in this patient was consistent with the results of nucleic acid tests and chest CT scans. In correlation analysis, HDL-cholesterol concentration was negatively correlated with C-reactive protein (CRP, r = -0.396, P < 0.001) and positively correlated with lymphocytes (r = 0.336, P < 0.001). The area under curve (AUC) in receiver operating characteristic (ROC) of HDL-cholesterol was 0.732 (P < 0.001), and, the adjusted odd ratio (OR) of HDL-cholesterol was 0.023 (95% CI 0.002-0.227).
Conclusions:
Decreased serum HDL-cholesterol is associated with the severity of COVID-19 infection.
