Increased Serum Levels of Uric Acid Are Associated with Sudomotor Dysfunction in Subjects with Type 2 Diabetes Mellitus

Abstract EN

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 age 63.1±2.6 years) and 40 age-, gender-, renal function- and T2DM duration-matched patients without sudomotor dysfunction (group B: mean age 62.1±3.1 years).

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.
