Significance of Microalbuminuria in Essential Hypertensive Subjects With Early Renal Injury and its Relation to High-sensitive C-reactive Protein / 医学研究杂志

ABSTRACT

Objective To investigate the association between microalbuminuria (MA) and high-sensitive C-reactive protein in essential hypertensive subjects. Methods Urinary albumin excretion rate (UAER)and the concentrations of high-sensitive C-reactive protein(hs-CRP) were measured. One hundred and eight patients with hypertension were divided into 2 groups normoalbuminuria and microalbuminuria group. concentrations of hs-CRP was compared between the two groups , and the association between MA and hs-CRP was evaluated.Results Patients with microalbuminuria were significantly characterized by higher systolic blood pressure (SBP) ,pulse pressure(PP) ,circulating fibrinogen and hs-CRP. Evaluation of bivariate correlation indicated that UAER was positively correlated with SBP , PP , body mass index (BMI) ,Serum creatinine (SCr), fibrinogen and hs-CRP. Multivariate regression analysis demonstrated PP, SCr and hs-CRP were independent risks associated with UAER.Conclusions Microalbuminuria is a sensitive marker in essential hypertensive subjects with early renal injury .hs-CRP is an independent risk associated with UAER ,which suggests that inflammation correlate with early renal injury in essential hypertension.
