title: [Cystatin C and adiponectin in diabetics with and without coronary artery disease].
abstract: BACKGROUND
  Patients with type 2 diabetes have a high incidence of coronary artery disease, which is even higher among those with renal failure. A serum level of cystatin C are used to assess renal function and is a potential cardiovascular risk factor. Adiponectin is an anti-atherogenic factor.
  
  
  OBJECTIVE
  To measure cystatin C and adiponectin in type 2 diabetic patients with and without coronary artery disease.
  
  
  METHODS
  Nine diabetic patients with coronary artery disease aged 76+/- 10 years, 20 diabetics without coronary artery disease aged 61 +/-5 years and 20 non diabetic subjects aged 57+/-10 years, were studied.
  
  
  RESULTS
  Serum levels of cystatin C (mg/L) were 1.5 (range 0.89-219), 0.81 (range 0.71-1.08) and 0.68 mg/L (range 055-0.75) in diabetics with and without coronary artery disease and controls, respectively (p <0.0001). No differences in adiponectin between groups and no association between cystatin C and adiponectin, were observed. No association between both parameters and body mass index orglycosilated hemoglobin Ale was observed. Cystatin C had a positive correlation with serum creatinine (r =0.57 p <0.001).
  
  
  CONCLUSIONS
  Diabetics with coronary artery disease have higher levels of cystatin C, that are closely correlated with serum creatinine levels.
