    We aimed to study the associations of 5 adipocytokines, two endothelial damage markers, and hs-CRP with the MetS components to distinguish the most significant cytokines likely related to distinct metabolic profiles. Methods: Cross-sectional study with 202 Chilean subjects (18–65 years old), categorized by MetS, and No-MetS according to Harmonizing ATP III. Adipocytokines profiling included adiponectin, leptin, hs-CRP, CTRP-1, PAI-1, FABP4, and metalloproteinase (MMP)-9 and MMP-2 activity. Results: Subjects with MetS showed higher levels of the most proinflammatories molecules but significantly lower adiponectin than subjects with No-MetS. Among the studied adipocytokines, PAI-1 and adiponectin showed the strongest associations with most of MetS components. PAI-1 was associate with MetS OR 1.107 [1.065–1.151], p< 0.0001, and adiponectin inversely associated with MetS OR 0.710 [0.610 -0.825], p< 0.0001). Following adjustment by sex, age, BMI, and 24 h sodium urinary excretion in a multivariate analysis, the association of PAI-1 OR 1.090 [1.044–1.137], p< 0.0001) and adiponectin OR 0.634 [0.519 - 0.775], p < 0.0001) with MetS remained significant. Multivariate analyses support a model where PAI-1associate to waist_hip, SBP, DBP, and glucose (all p< 0.0001) and adiponectin associate to TG (p=0.03) and HDL-cholesterol (p=0.0001). Conclusion: PAI-1 and Adiponectin rendered the most robust associations with MetS components in a general population, indicating that unfavourable adipose tissue performance is a key contributor to these metabolic anomalies. Further prospective analyses should allow establishing whether these adipocytokines can anticipate the progress of MetS and cardiovascular risk.
