title: Plasma ghrelin and interleukin-6 levels correlate with body mass index and arterial blood pressure in males with essential hypertension.
abstract: We examined an association between ghrelin, including its major isoforms, interleukin-6 (IL-6), body mass index (BMI), and mean arterial pressure (MAP) in male overweight patients with essential hypertension. Twenty hypertensive male patients with newly diagnosed essential hypertension (EH) before starting drug treatment and 22 age-matched healthy controls were enrolled in the study. Fasting total plasma ghrelin (TGhr), acyl ghrelin (AGhr), des-acyl ghrelin (DGhr) and IL-6 were determined and correlations between studied parameters were calculated. We found significantly lower total plasma ghrelin and higher plasma IL-6 in hypertensives when compared with the control. In patients with hypertension the negative correlations were found: between TGhr and BMI, DGhr and BMI, TGhr and MAP, and between DGhr and MAP. IL-6 positively correlated with BMI and MAP in hypertensive subjects. No correlations between all forms of ghrelin and IL-6 were noted. The changes in plasma ghrelin and IL-6 contribute independently to the elevated blood pressure in essential hypertension. Negative correlation of DGhr and MAP may suggest its hemodynamic involvement in regulation of blood pressure.
