Increased Serum Levels of Uric Acid Are Associated with Sudomotor Dysfunction in Subjects with Type 2 Diabetes Mellitus
The aim of this paper was to assess serum uric acid (SUA) levels in patients with type 2 diabetes mellitus (T2DM) with or without sudomotor dysfunction (evaluated by the Neuropad test). We included 36 T2DM patients with sudomotor dysfunction (group A: mean age63.1±2.6years) and 40 age-, gender-, renal function- and T2DM duration-matched patients without sudomotor dysfunction (group B: mean age62.1±3.1years). SUA was significantly higher in group A (P<0.001). There was a significant correlation between SUA and Neuropad time to colour change in both groups (group A:rs=0.819,P<0.001; group B:rs=0.774,P<0.001). There was also a significant positive correlation between SUA and CRP in both groups (group A:rs=0.947,P<0.001; group B:rs=0.848,P<0.001). In conclusion, SUA levels were higher in T2DM patients with sudomotor dysfunction than those without this complication. The potential role of SUA in sudomotor dysfunction merits further study.
