Altered lipid profile in patients with COVID-19 infection

ABSTRACT

Background: In this study, we aimed to investigate the pathological alterations of LDL-cholesterol, HDL-cholesterol, total cholesterol and triglycerides in COVID-19 patients during the acute phase of infection, and after recovery. Method(s) A retrospective study was performed to examine serum levels of LDL-cholesterol, HDL-cholesterol, total cholesterol and triglycerides on 55 COVID-19 patients who were hospitalized in our center between February and April 2020. The lipid profile and the hematological parameters were analyzed in the same group of patients before (Group before) and after clinical management (Group after). The laboratory tests results were compared between these two groups, as well as with a group of healthy subjects (Healthy controls), matched for age and sex and selected among the blood donors. Result(s) LDL-cholesterol, HDL-cholesterol, total cholesterol levels were significantly lower in COVID-19 patients (Group before) as compared with normal subjects (P<0.0001). Comparing healthy controls and the group after, statistically significant differences were observed for all parameters except for total cholesterol (P=0.9006). Total cholesterol, HDL-cholesterol, LDL-cholesterol and triglyceride were found to be significantly higher after recovery than during the acute phase of infection (P<0.0001). C-reactive protein levels were found to be inversely correlated with those of LDL-cholesterol (rs =-0573, P<0.0001), total cholesterol (r=-0.732, P<0.0001), and HDL-cholesterol (r=-0.700, P<0.0001). Conclusion(s) The results of our study seemingly attest that lipids, especially cholesterol, may play an important role in viral replication, internalization and immune activation in patients with COVID-19 infection. Moreover, lipid abnormalities observed during and after this infection could be used for assessing indirectly the response to clinical treatment.Copyright © Journal of Laboratory and Precision Medicine.
