Cistatina C y adiponectina en pacientes diabéticos tipo 2 coronarios y no coronarios / 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. Aim: To measure cystatin C and adiponectin in type 2 diabetic patients with and without coronary artery disease. Material and 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 =0.57p <0.001). Conclusions: Diabetics with coronary artery disease have higher levels of cystatin C, that are closely correlated with serum creatinine levels.
