Abstract
AIMS: To examine whether high-sensitivity C-reactive protein (hs-CRP) can predict all-cause death in Chinese adults with hyperglycemia. METHODS: All the 237 diabetes and 49 prediabetes recruited in the study were evolved from the participants with impaired glucose tolerance in the original Da Qing Diabetes Study. Blood hs-CRP level was measured at 2006. Ten-year outcome of death was traced from 2006 to 2016. Cox model was used to analyse the association between hs-CRP level and the risk of all-cause death occurred over the subsequent 10 years. RESULTS: During the follow-up, death occurred in 36 (37.9%) subjects in the highest hs-CRP tertile group (hs-CRP > 2.16 mg/L) and 19 (20.0%) in the lowest hs-CRP tertile group (hs-CRP < 0.82 mg/L, p < 0.05). The corresponding incidence of all-cause death (per 1,000 person-years) was 44.7 (95% CI 30.1-59.3) and 21.6 (95% CI 11.9-31.3) in the two groups respectively (p < 0.0001). The highest hs-CRP tertile was associated with the increased risk of all-cause death significantly (hazard ratio 1.88, 95% CI 1.07-3.32) after controlling for traditional risk factors. CONCLUSIONS: Serum hs-CRP was predictive of 10-year all-cause death in Chinese adults with hyperglycemia, suggesting the impact of low-grade inflammation on mortality deserves more attention.
