Abstract

Aim: Glycated albumin (GA) is recognized as a reliable marker for monitoring glycemic control particularly in patients with end-stage renal disease (ESRD). Here, we investigated the impact of GA levels on long-term survival in diabetic patients with ESRD. Methods: We enrolled ESRD patients with diabetic nephropathy into our single-centre prospective follow-up study (n = 98, 66 men and 32 women; age 68.2 12.3 years) with a mean follow-up period of 47.7 months. All patients had started haemodialysis between December 1992 and November 2003. They were categorized into two groups according to their GA levels at the initiation of haemodialysis; GA < 29% (low-GA group; n = 54) and GA 29% (high-GA group; n = 44). Results: Between low-GA and high-GA groups, there were no significant differences in various clinical parameters except GA and HbA1c levels. The cumulative survival rate of low-GA group was significantly higher than that of high-GA group (P = 0.034, log-rank test). After adjustment for age, sex, total cholesterol, C-reactive protein and albumin, high-GA was a significant predictor of survival (hazard ratio 1.042 per 1.0% increment of GA, 95% CI 1.014-1.070, P < 0.05), but not in the case with HbA1c. Cox proportional hazard model demonstrated that high-GA group was a significant predictor for cardiovascular death (hazard ratio 2.971 (1.064-8.298), P = 0.038). Conclusion: We conclude that poor glycemic control (GA 29%) before starting haemodialysis is associated with increased cardiovascular morbidity and shortened survival in diabetic patients with ESRD.
