Proportional correlates of adipolin and cathepsin S in metabolic syndrome patients with and without prediabetes.

BACKGROUND:Adipolin and cathepsin S are intricately involved in pathophysiology of metabolic syndrome (MetS) and prediabetes (PreDM). AIMS & METHODS:This cross-sectional study aimed to compare and correlate between these metabolic biomarkers as well as between them and adiposity, atherogenicity and hematological indices in MetS patients. Our cross-sectional study involved recruiting 29 normoglycemic MetS, 30 newly diagnosed drug naïve PreDM-MetS patients versus 29 lean, healthy and normoglycemic controls. RESULTS:Adipolin and cathepsin S plasma levels were significantly higher in both MetS (normoglycemic and PreDM) groups vs. healthy controls. Evidently proportional adipolin-cathepsin S association was markedly signified in 59 MetS participants (normoglycemic and PreDM). Distinctively unlike adipolin, inverse cathepsin S-diastolic blood pressure (DBP) but direct cathepsin S-monocyte count and its monocyte -to- lymphocyte ratio cross-correlated were marked. Notably unlike cathepsin S, adipolin was positively associated with each of FPG, A1C and TG, visceral adiposity index, lipid accumulation product and atherogenic index of plsama in the MetS pool of participants (N = 59). CONCLUSIONS:Given the intergroup discrepancies in adiposity, atherogenicity indices and their correlations (as well as hematological indices) with biomarkers; this cross-sectional study cannot rule out either biomarker as an associative predictor or as a surrogate indicator and putative prognostic tool for the prediction/prevention and treatment of metabolism dysregularities.
