AIM: It is important to explore predictive markers other than conventional cardiovascular risk factors for early detection and treatment of chronic kidney disease (CKD), a major risk factor for end-stage renal failure. We hypothesized that serum albumin and high-sensitivity C-reactive protein (hs-CRP) to be independent markers, and examined their associations with the risk of CKD. METHODS: We examined the associations of serum albumin and hs-CRP levels with the risk of incident CKD, in 2535 Japanese adults aged 40-69 years without CKD at baseline during a median 9.0-year follow-up after adjustment for known cardiovascular risk factors. RESULTS: During the follow-up period, 367 cases of CKD developed. In multivariable analyses adjusted for known risk factors, the CKD hazard ratios (95% confidence intervals) for the highest versus lowest quartiles of serum albumin levels were 0.69 (0.40-1.17) for men and 0.42 (0.28-0.64) for women. Corresponding values for hs-CRP were 0.95 (0.54-1.67) for men and 1.85 (1.25-2.75) for women. The association of combined serum albumin and hs-CRP with the risk of CKD was examined for women. The hazard ratio was 1.72 (1.17-2.54) for low versus higher albumin levels at lower hs-CRP levels, but such an association was not observed at high hs-CRP level. The hazard ratio was 1.96 (1.44-2.66) for high versus lower hs-CRP levels at higher serum albumin levels, but such association was not observed at low serum albumin level. CONCLUSION: Both low serum albumin and high hs-CRP levels were predictive of CKD for women.
