Objective To investigate the expression characteristics of serum resistin(RETN)and Beclin-1 in patients with gouty arthritis(GA),and to analyze the relationship between RETN and GA clinical charac-teristics and clinical efficacy.Methods A total of 82 GA patients(GA group)and 60 healthy volunteers(con-trol group)in Dongguan People's Hospital from January 2019 to December 2022 were enrolled in the study.The expressions of serum RETN and Beclin-1 in GA patients were detected before and after treatment(on the physical examination day of the control group),and the differences of serum RETN and Beclin-1 in GA pa-tients with different clinical characteristics and efficacy were compared.Pearson correlation analysis was used to investigate the correlation between serum RETN,Beclin-1 expression and uric acid(UA)level in GA pa-tients.The diagnostic value of serum RETN and Beclin-1 in GA was analyzed using the receiver operating characteristic(ROC)curve.Results The serum RETN level in the GA group was higher than that in the con-trol group,and the expression of Beclin-1 was lower than that in the control group(P<0.05).The serum RETN levels in GA patients with acute stage,disease duration≥5 years,affected joints≥5,annual attack fre-quency≥3 times were higher than those in GA patients with chronic stage and intermittent stage,disease du-ration<5 years,affected joints<5,annual attack frequency<3 times(P<0.05),and the expression of Bec-lin-1 were lower than those in GA patients in chronic and intermittent stages,disease duration<5 years,af-fected joints<5,annual frequency<3 times(P<0.05).The serum UA level in GA patients was positively correlated with RETN(r=0.674,P<0.05),and negatively correlated with Beclin-1 expression(r=-0.568,P<0.05).After treatment,the serum expression of level RETN in the effective group was lower than that in the ineffective group,while the level Beclin-1 was higher than that in the ineffective group(P<0.05).The ar-ea under the curve of combined RETN and Beclin-1 diagnosis for GA was 0.921,which was higher than that of individual diagnosis(Z=3.752,3.154,P<0.05).Conclusion Serum RETN level increases,and Beclin-1 ex-pression decreases in GA patients,which is associated with increased UA level,prolonged acute stage and course of GA,increased number of affected joints and annual attack frequency,and treatment ineffectiveness.RETN and Beclin-1 could serve as biomarkers for GA diagnosis.
