  Purpose

Hyperuricemia is emerging as a risk factor for development of diabetes and metabolic syndrome. Recently, it was shown in in-vitro cell culture experiments that hyperuricemia induces redox-dependent signaling and oxidative stress in adipocytes. By targeting levels of uric acid with febuxostat we hypothesize that the levels of oxidative stress in adipose tissue (obtained by fat biopsy) will decrease.

Primary aims of the study is to determine whether febuxostat therapy in overweight or obese, diabetic patients with stage 3 CKD and high serum uric acid levels

  1. decreases adipose tissue concentrations of thiobarbituric acid reactive substance (TBARS), a marker of oxidative stress
  2. increases adipose tissue expression and concentrations of adiponectin and
  3. decreases urinary concentrations of transforming growth factor (TGF)- B1.

Primary Outcome Measures:
  • Effects of Febuxostat on TBARS, adiponectin and transforming growth factor [ Time Frame: 6 months ] [ Designated as safety issue: No ]

    To determine whether febuxostat therapy in overweight or obese, diabetic patients with stage 3 CKD and high serum uric acid levels

    1. decreases adipose tissue concentrations of thiobarbituric acid reactive substance (TBARS), a marker of oxidative stress
    2. increases adipose tissue expression and concentrations of adiponectin and
    3. decreases urinary concentrations of transforming growth factor (TGF)- B1.


Secondary Outcome Measures:
  • Effects of Febuxostat on plasma adiponectin, TNF-alpha, IL-6, hsCRP and albumin [ Time Frame: 6 months ] [ Designated as safety issue: No ]

    To determine whether febuxostat therapy in overweight or obese, diabetic patients with stage 3 CKD and high serum uric acid levels

    1. increases plasma concentrations of adiponectin
    2. decreases adipose tissue expression and concentrations of TNF-alpha and IL-6 and
    3. decreases plasma concentrations of TNF-alpha, IL-6 and high sensitivity C-reactive protein (hsCRP) and
    4. decreases urinary concentrations of albumin
