The aim of ...Metabolic syndrome (MetS) and its components have been linked to elevated serum levels of inflammatory biomarkers such as C-reactive protein, interleukin-6, interleukin-1β and tumor necrosis factor alpha. The aim of our study was to address the association between MetS components with serum hs-CRP and IL-6 levels among Congolese adults. A total of 357 participants (aged 30 - 87 years) were included in this cross-sectional study. Anthropometrics were collected and fasting blood sampled for assessment of fasting blood glycaemia (FBG), lipids and inflammatory parameters using commercially available assays. NCEP-ATPIII criteria were used to define MetS. The Median (IQR) hs-CRP and IL-6 levels were higher in participants with MetS than in those without ([7 (4, 14) versus 6 (4, 8)] mg/L;p = 0.092 and [23.8 (20.9, 27.6) versus 22.3 (19.5, 25.0)] pg/mL;p = 0.002). hs-CRP and IL-6 levels were significantly higher in females with MetS than in those without, but not in males. Among participants, only TG was correlated with hs-CRP (r = 0.149, p = 0.007), and a significant correlation was observed between TG (r = 0.116, p = 0.037), FBG (r = 0.208, p = 0.000), HDL-C (r = −0.119, p = 0.034) and SBP (r = 0.143, p = 0.010) and IL-6. In males, hs-CRP levels were positively correlated with TG (0.316;p = 0.000), negatively with HDL-C (r = −0.290, p = 0.0022), without such correlations in females. In Ames, IL-6 levels were positively correlated with FBG (r = 0.202;p = 0.035), and negatively with HDL-C (r = −0.249, p = 0.009). Significant correlations between IL-6 levels and FBG (r = 0.214;p = 0.000) or SBP (r = 0.227, p = 0.000) were observed in females. Logistic regression analysis was carried out to identify the relationship between MetS components and hs-CRP or IL-6. Values of area under receiver-operating characteristic (ROC) curves suggest potential use of serum hs-CRP (AUC = 0.675) and IL-6 (AUC = 0.656) as diagnostic biomarkers of MetS. Combination of hs-CRP and IL-6 improved diagnosis accuracy, yielding a 0.698 ROC curve area. MetS components are associated with hs-CRP and IL-6 levels among adults Congolese. Combining the two biomarkers hs-CRP and IL-6 improves Mets diagnostic accuracy compared to hs-CRP or IL-6 alone.展开更多
