Uricemia and metabolic syndrome in patients with arterial hypertension
2012
OBJECTIVE: Serum urate levels have been associated with metabolic syndrome (MS). However, the relationship between these two variables in patients with essential arterial hypertension has not been studied. PATIENTS AND METHODS: A Cross-sectional study in 592 patients with essential hypertension. The MS was defined according to the ATP-III criteria. We excluded patients with hypouricemic treatment. RESULTS: The prevalence of MS was 52% (95% CI, 48-56%) and there was a graded increase with increasing serum urate (uricemia ≤ 4.7 mg/dl, 36%; uricemia ≥ 6.8 mg/dl, 70%, P 7.0 mg/dL; women, > 6.0 mg/dL) in hypertensive patients without diuretic treatment, was 24% (in those with MS 40% versus 11% without MS). In multivariate analysis, triglycerides (OR = 1.008, CI 95%: 1.004-1.012, P < 0.001) and body mass index (BMI) (OR = 1.118, CI 95%: 1.059-1.181, P < 0.001), were independent predictors of serum uric acid levels. CONCLUSIONS: In patients with essential hypertension, about half have MS and one out of four has hyperuricemia. The most important determinant of hyperuricemia is BMI.
