OBJECTIVES: To determine the independent effect of high-sensitivity C-reactive protein (hs-CRP) and the combined effects of hs-CRP and other traditional risk factors on microalbuminuria in hypertensive patients during the 3-year follow-up period.
METHODS AND RESULTS: Baseline hs-CRP levels and other risk factors were measured in 280 adults in 2007. In the third year of examination, 199 patients (mean age 62.5 ± 9.5, men 59.3%) were approached for the measurement of microalbuminuria. The subjects were classified into two groups by the median of baseline hs-CRP. Compared to the patients with baseline hs-CRP below the median group ( n = 99, 50%), the group with baseline hs-CRP above the median ( n = 100, 50%) had higher urinary albumin-to-creatinine ratio (ACR) ( P = 0.007) at the end of follow-up period. ACR at the end of follow-up period was significantly correlated with baseline diabetes ( β = 0.342; P < 0.001), baseline SBP ( β = 0.148; P = 0.02), and baseline log-transformed hs-CRP ( β = 0.169; P = 0.01), while adversely correlated with baseline estimated glomerular filtration rate (eGFR) ( β = -0.163; P = 0.02) in multivariate stepwise linear analysis. In addition, ACR change during follow-up period was significantly correlated with baseline diabetes ( β = 0.359; P < 0.001) and baseline log-transformed hs-CRP ( β = 0.190; P = 0.004) in multivariate stepwise linear analysis. The combined effects of baseline hs-CRP and conventional risk factors, such as male sex, diabetes, smoking status, hyperlipidemia, hyperuricemia, and mildly reduced eGFR had a greater risk for microalbuminuria progression. There was no difference in eGFR changes during the follow-up period between two groups.
CONCLUSION: Our findings offer a new piece of evidence on the predictive value of baseline hs-CRP for microalbuminuria progression in essential hypertensive patients, and highlight those who combined with traditional cardiovascular risk factors had a greater risk for developing microalbuminuria.
