Abstract:
OBJECTIVE:To explore the change of plasma level of chemerin in chronic obstructive pulmonary disease (COPD) patients and its relationship with lipid metabolism.
METHODS:A total of 150 COPD patients were randomly selected and set as the COPD group and 30 healthy persons were set as the control group. The COPD group was further divided into a thin group (BMI<18.5 kg/m2, n=116) and a normal weight group (BMI≥18.5 kg/m2, n=34) according to their body mass index (BMI). Enzyme-linked immunosorbent (ELISA) was used in detection of plasma chemerin, total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL), and high-density lipoprotein (HDL). The hospitalization rate in a half year and the mortality was statistically analyzed. Pearson correlation analysis was applied to analyze the relationship between plasma level of chemerin and levels of blood lipids, and Spearman rank correlation method was used to analyze the relationship between the plasma levels of chemerin or lipids and the prognosis.
RESULTS:Compared with the control group, plasma levels of TC, TG and HDL in the COPD group in acute exacerbation and remission stage were reduced, while plasma levels of chemerin and LDL was elevated; compared with the thin group, plasma levels of TC, TG and HDL in the normal weight group were elevated, while plasma levels of chemerin and LDL were decreased. The hospitalization rate in half year and the mortality in the thin group were higher than that in the normal weight group, and the plasma levels of TC, TG and HDL in the COPD patients with hospitalization in half year or death were lower than that in COPD patients without hospitalization, while the plasma levels of chemerin and LDL was increased (P<0.05). Pearson correlation analysis showed that plasma level of chemerin in COPD patients was negatively correlated with plasma levels of TC, TG and HDL (r=-0.695, -0.748, -0.695, P<0.05), while positively correlated with plasma levels of LDL (r=0.668, P<0.05). Spearman rank correlation analysis showed that plasma levels of TC, TG and HDL in COPD patients and hospitalization rate in half year as well as the mortality were negatively correlated (TC: r=-0.716, -0.737; TG: r=-0.748, -0.753; HDL: r=
-0.736, -0.728, P<0.05), while the plasma level of chemerin or LDL and hospitalization rate in half year and the mortality were positively correlated (chemerin: r=0.753, 0.766; LDL: r=0.742, 0.755, P<0.05).
CONCLUSION:Plasma levels of chemerin in the COPD patients are correlated with lipid metabolism. Plasma levels of chemerin and lipid are related to prognosis of COPD. The plasma levels of chemerin in patients with COPD may reflect the lipid metabolism and could be served as the index for prognostic evaluation.
