OBJECTIVE: Uric acid to albumin ratio (UAR) reflects inflammatory activity and its predictive value has been shown in various diseases. In this study, we sought to evaluate the value of uric acid to albumin ratio in patients with peripheral arterial disease (PAD).

PATIENTS AND METHODS: Two hundred forty-three PAD patients were divided into TransAtlantic Inter-Society Consensus-II (TASC-II) A-B and TASC-II C-D groups, according to their TASC-II classification. Biochemical variables of the patients were recorded, and the UAR of each patient was calculated.

RESULTS: Patients who had TASC-II A-B disease were younger than the patients who had TASC-II C-D disease (60.7±8.71 vs. 63.28±8.8 years, p=0.024). Quade ANCOVA results showed that patients with TASC-II C-D disease had higher values of UAR when age was used as a covariate (t=-5.045, p<0.001). Lymphocyte count was significantly lower, and UAR was significantly higher in patients with TASC-II C-D disease (p=0.035 and p<0.001, respectively). UAR and lymphocyte count showed a significant positive correlation and a negative correlation with the TASC-II class of the disease (r=0.403, and r=-0.299, p<0.001 for both). A UAR of 1.54 predicted TASC-II C-D disease with a sensitivity and specificity of 57.9% and 78.8%, respectively. UAR predicted severe PAD with an OR of 3.723.

CONCLUSIONS: UAR was a better tool for predicting TASC-II C-D disease compared to uric acid and albumin levels. UAR is an easily calculable parameter that can be used in clinical practice.
