Preprints with The Lancet is part of SSRN´s First Look, a place where journals and other research experts identify content of interest prior to publication. These preprint papers are not peer-reviewed. Authors have either opted in at submission to The Lancet family of journals to post their preprints on Preprints with The Lancet, or submitted directly via SSRN. The usual SSRN checks and a Lancet-specific check for appropriateness and transparency have been applied. Preprints available here are not Lancet publications or necessarily under review with a Lancet journal. These papers should not be used for clinical decision making or reporting of research to a lay audience without indicating that this is preliminary research that has not been peer-reviewed.

Abstract

Background: A recent cluster of pneumonia cases in Wuhan, China, was caused by a novel coronavirus COVID-19. Meanwhile, as the infection progressed, a large number of cases were also diagnosed in Wenzhou, China. The objective of the study is to describe the clinical laboratory features, especially lipid profile of the patients with COVID-19 infection in Wenzhou.



Methods: All cases were in a designated hospital in Wenzhou, and confirmed by positive virial nucleic acid detection through PCR assay. All clinical laboratory data were from the first test results after their admission. The unpaired t test was used for data analysis.



Findings: The absolute value of white blood cells, neutrophils and lymphocytes were lower than healthy controls ( P ＜0.05), more significantly, the patients had sharply decreased total cholesterol (TC), HDL-cholesterol and LDL-cholesterol levels ( P ＜0.001), 3.70±0.09mmol/L, 1.18±0.03 mmol/L and 1.82±0.08 mmol/L respectively, and increased monocyte/HDL-cholesterol ratio (0.37±0.02 vs 0.28±0.01 in healthy control). Among the patients, the primary infection cases showed the lower HDL-cholesterol levels (1.10±0.04 mmol/L) and higher monocyte/HDL-cholesterol ratio (0.43±0.03) than the secondary infection cases by person-to-person transmission ( P ＜0.05). Compared with the female patients, the male patients had higher levels of monocytes [(0.46±0.02) ×10 9 /L], M/HDL-C ratio (0.44±0.02), and lactate dehydrogenase (LDH, 257.6±12.32 U/l).



Interpretation: Low serum cholesterol level in the patients with COVID-19 in Wenzhou, China. Altered serum cholesterol provide important information, and is meaningful to understand the disease.
