Abstract
Background and Objectives: This study was to characterize the association of cumulative exposure to increased high-sensitivity C-reactive protein (hs-CRP) with chronic kidney diseases (CKD). Methods: We included 35,194 participants with hs-CRP measured at three examinations in 2006, 2008, 2010. Participants were classified into nonexposed group (hs-CRP 2 or urinary protein positive. Results: The study showed the risk of CKD as the number of years of exposure to hs-CRP increases. Participants in 3-exposed group had significantly increased CKD risk with hazard ratio (HR) (95% confidence interval, CI) of 1.70 (1.49–1.93), in comparison with 1.47 (1.34–1.62) for participants in the 2-exposed group, and 1.08 (1.00–1.16) for those in the 1-exposed group (p < 0.01); meanwhile, the similar and significant associations were also observed for eGFR 2, proteinuria positive, in participants of the 3-exposed group in comparison with the nonexposed group, with respective HRs (95% CI) of 1.27 (1.01–1.58) and 2.27 (1.87–2.76). Conclusions: Cumulative exposure to hs-CRP was associated with a subsequent increased risk of CKD and was of great value to risk prediction.Keywords
