Abstract:
Objective To investigate the role of adiponectin (ADP) and its receptors (ADR) in pati ents with primary gouty arthritis (GA).Methods Enzyme-linked immunosorbent assay (ELISA) was used to determine the levels of plasma ADP in 88 GA and 80 healthy controls (NC).Real time quantitative polymerase chain reaction (RT-qPCR) was employed to study the expression of ADR1 and ADR2 mRNA in peripheral blood mononuclear cells (PBMCs).The biochemical indicator of TG,HDL,LDL,VLDL,apoA1,apoB100 and uric acid (UA) were detected at the same time.T test,Spearman's correlations and regression analysis were used for statistical analysis.Results The concentration of plasma ADP was significantly lower in GA than that in NC [(6±7) μg/ml,(8±6) μg/ml,t=-3.71,P＜0.01 ],the expression of ADR1 and ADR2 mRNA in GA (ADR1:0.09±0.08,ADR2:0.0122±0.0164) was significantly increased when compared to the NC (ADR1:0.05±0.03,ADR2:0.0054±0.0024) (t=2.71,2.35,P＜0.05).In the GA patients,the level of ADP was negatively correlated with the lymphocytes count (LY) and UA (r=-0.32,-0.36,P＜0.05),and it was positively correlated with ESR and LDL level (r=0.31,0.39,P＜0.05).The expression of ADR1 mRNAwas negatively correlated with TG (r=-0.43,P＜0.05 ),but positivdy correlated with ESR and CRP level (r=0.45,0.57,P＜0.05).The expression of ADR2 mRNA was negatively correlated with glucose and UA(r=-0.50,-0.59,P＜0.05).Conclusion Altered expression of ADP and its receptors may be involved in thepathogenesis of gouty inflammation.
