RESUMO
BACKGROUND AND AIM: Adipocytokine dysfunction is considered as causative factor of target organ damage in metabolic disease. The aim of the study was to investigate whether altered adipocytokine profile predicts left ventricular (LV) remodeling in hypertensive patients with type 2 diabetes mellitus (T2DM). METHODS: A total of 186 patients (125 hypertensive and 61 non-hypertensive individuals) with established T2DM and 20 healthy volunteers were enrolled in the study. LV remodeling was determined at baseline. Concentrations of adipocytokines were measured with ELISA at baseline. RESULTS: The most important predictors of LV hypertrophy in T2DM patients were serum levels of omentin-1 (B-coefficient = -0.64, p = 0.001), Zinc-α2-glycoprotein [ZA2G] (B-coefficient = -0.57, p = 0.002), visfatin (B-coefficient = 0.26, p = 0.034), hs-CRP (B-coefficient = 0.38, p = 0.002), HOMA-IR (B-coefficient = 0.34, p = 0.001), age (B-coefficient = 0.31, p = 0.022), glypican-4 (B-coefficient = -0.23, p = 0.042), and male sex (B-coefficient = 0.11, p = 0.048). After entering combined depending variable (LV hypertrophy and LV diastolic dysfunction) to the model the significant predictors remained serum levels of omentin-1 (B-coefficient = -0.82, p = 0.001), ZA2G (B-coefficient = -0.54, p = 0.001) and HOMA-IR (B-coefficient = 0.44, p = 0.001). Regression analyses showed that the most influential determinants of depending variable (LV hypertrophy + LV diastolic dysfunction) in T2DM patients were omentin-1 (B-coefficient = -1.6, p = 0.001) and ZA2G (B-coefficient = -0.78, p = 0.044). CONCLUSION: We found that serum levels of omentin-1 and ZA2G were the most important predictors for LV hypertrophy + LV diastolic dysfunction in T2DM patients. Large clinical trials are required to confirm this assumption and get clear explanation of issues unveiled.
