چکیده
BACKGROUND Hypoadiponectinemia is a well-known state associated with metabolic syndrome (MetS) and insulin resistance (IR). Recently aldosterone has been highly associated with high blood pressure, and may thus be a possible biomarker for MetS and IR. In this study, we investigate the association of aldosterone with MetS and IR, and compare it with that of adiponectin. METHODS In this cross-sectional study, we recruited 556 women receiving physical examinations at a general hospital in central Taiwan. At the time of examination, we collected data on various demographic and physical characteristics and measured blood levels of aldosterone, adiponectin and a variety of metabolic factors. Multiple linear regression analysis was performed using adiponectin or aldosterone as the dependent variables. RESULTS We found an inverse correlation between blood adiponectin and aldosterone (γ = -0.11, P = 0.009). Adiponectin levels were lower and aldosterone levels higher in women with MetS that those without (8.1 ± 0.4 vs. 11.5 ± 0.2 μg/mL, P < 0.001 and 691 ± 50 vs. 560 ± 11 pmol/L, P = 0.013, respectively), as they were in women with and without IR (adiponectin 10.4 ± 0.5 vs. 11.3 ± 0.2 μg/mL, P = 0.003 and aldosterone 635 ± 31 vs. 560 ± 11 pmol/L, P = 0.022). Although aldosterone was significantly related to body fat %, fasting plasma glucose and serum creatinine levels, the relationship between adiponectin and aldosterone was not obvious after adjustment in the multivariate analysis. CONCLUSION Although aldosterone was related to metabolic factors, including body fat % and fasting plasma glucose in our female subjects, the relationship between aldosterone and adiponectin remains unclear.

متن کاملHigh Serum Ferritin Concentrations in Polycystic Ovary Syndrome Is Not Related to Insulin Resistance
OBJECTIVE: Some data are available on the association between components of the insulin resistance syndrome and serum ferritin. Insulin resistance is observed in patients with polycystic ovary syndrome (PCOS) We hypothesize that body iron stores might be increased in these women. MATERIALS AND METHODS: Two hundred and six people (103 PCOS patients and 103 healthy women who were matched for a...

A large body of evidence suggests that aldosterone excess is a common cause of hypertension with a prevalence of primary aldosteronism (PA) of 10% in patients with mildto-moderate hypertension and 20% in patients with resistant hypertension.1 Experimental and clinical data also demonstrate that aldosterone excess contributes importantly to the development and progression of cardiorenal disease....

متن کاملPlasma aldosterone is independently associated with the metabolic syndrome.
The aim of this study was to analyze the associations of plasma aldosterone and plasma renin activity with the metabolic syndrome and each of its components. We analyzed data from a family based study in the Seychelles made up of 356 participants (160 men and 196 women) from 69 families of African descent. In multivariable models, plasma aldosterone was associated positively (P < 0.05) with blo...
