Serum adiponectin concentrations in patients with essential hypertension

To explore the serum levels of adiponectin in patients with essential hypertension and the relationbetween adiponectin and blood pressure. Methods: Forty-five cases with essential hypertension and 43 healthy control sub-jects have been taken fasting blood samples for measurements of plasma glucose, plasma lipids, insulin, C-peptide, thyroidhormones, TNF-α, leptin and adiponectin. Glucose tolerance was assessed by 75-g oral glucose tolerance est. Results: Theconcentrations of adiponectin in cases with essential hypertension were significantly lower than those in the control group(4.15 ± 1.99 vs 7.04 ± 3.13 mg/ml, P = 0.000). Pearson relation analysis showed that serum adiponectin concentrationswere negatively and significantly correlated with body-mass index ( r = - 0. 274, P = 0. 038 ), total cholesterol(r = -0.257, P = 0.048)in control groups, while adiponectin concentrations were negatively and significantly correlatedwith systolic blood pressure ( r = - 0.356, P = 0.016), triglyceride ( r = - 0.367, P = 0.013), tumor necrosis factor-al-pha ( r = - 0. 298, P = 0.047) and triiodothyronine ( r = - 0.317, P = 0. 034) in essential hypertension group. Multipleregression analysis showed that body-mass index was the independent factor to adiponectin levels, and SBP and TNF-α wereadiponectin independent factors in the essential hypertension group. Conclusion: The serum adiponectin concentrations aresignificant lower in patients with essential hypertension, and there is negative and significantly correlation between adiponec-tin and blood pressure.
