Background To investigate the association of serum uric acid level with renal function change in patients with type 2 diabetes mellitus (T2DM). Methods T2DM patients who had been followed-up for at least 3 years were included. Participants were categorized into stable, progression, or regression groups according to their change in chronic kidney disease (CKD) stage. During the follow-up period, all numeric values of metabolic factors, including the uric acid level and the medication possession rate, were calculated in order to investigate their associations with CKD development. Multivariate Cox regression analyses were used to identify independent factors associated with change in CKD. Results A total of 2367 T2DM patients were enrolled in this study and followed-up for a mean of 4.6 years. The numbers of patients in the stable, progression and regression groups were 1133 (47.9%), 487 (20.6%), and 747 (31.5%), respectively. The progression group had the highest serum uric acid level (6.9 +/- 1.8 mg/dL), and the regression group had the lowest uric acid level (5.4 +/- 1.5 mg/dL). In addition, we found that the serum uric acid level was an independent factor associated with CKD progression when the value exceeded 6.3 mg/dL. A lower uric acid level could be beneficial for CKD improvement in T2DM patients with stage 3-5 CKD. Conclusions Our data indicated that the serum uric acid level is associated with CKD regression and progression and suggested that a high normal serum uric acid level should be closely monitored in patients with T2DM.
