Abstract:
Objective To study the association between serum free fatty acid (FFA) and ankylosing spondylitis (AS).Methods According to the classification criteria,a total of 90 newly diagnosed AS patients,223 healthy individuals and 82 patients with non-inflammatory diseases were divided into three groups,and biochemistry and immunology biomarks were measured in all individuals.One-Way analysis of variance (ANOVA) test was used to compare the difference between the three groups in the serum indexes,and Logistic regression analysis was used to identify AS risk factors associated with AS.Results There were no significant differences in gender,age,body mass index (BMI),white blood cells (WBC),high-level data link control (HDL-C),low-density lipoprotein control (LDL-C),lipoproteins [Lp (a)],alkaline phosphatase (ALP) and TG in the three groups,and our results showed that serum FFA was statistical different between the three groups (F=24.191,P＜0.01),the serum level of FFA in patients with AS was higher compared with patients with noninflammatory diseases and healthy controls [(0.48 ±0.18) mmol/L,(0.28 ±0.09) mmol/L,(0.29±0.16) mmol/L;t=-5.969,P＜0.01;t=5.106,P＜0.01].Seral IgA,IgG,IgM levels,ESR and CRP were statistically different between the three groups (F=14.870,P＜0.01;F=16.464,P＜0.01;F=4.124,P=0.018;F=97.002,P＜0.01;F=22.069,P＜0.01).Gender,age,BMI,serum IgA,IgM,ALP,HDL-C,LDL-C,Lp(a) and TG levels were not associated with AS by logistic regression analysis.However,serum IgG level,ESR and CRP were associated with AS [OR05％CI):1.659(1.032,2.660),P=0.037;OR05％CI):1.340(1.005,1.787),P=0.046;OR05％CI):1.820 (1.025,3.232),P=0.041],and there is an association between FFA and AS was observed in logistic regression analysis (OR=1.132,95％CI:1.014-1.421,P=0.033).Conclusion We suggest that incre-ased FFA is closely associated with AS,and may be an underlying risk factor for AS.
