Adiponectin may play a part in the pathogenesis of diabetic retinopathy
Abstract
To measure plasma adiponectin concentrations in patients with type 2 diabetes and to investigate any association with the severity of diabetic retinopathy, because adiponectin seems to be an important modulator for metabolic and vascular diseases. Seventy-four patients (mean age 46.8+/-5.1 years; body mass index (BMI), 26.8+/-2.10 kg/m(2)) and 54 healthy volunteers (mean age 46.8+/-5.4 years; BMI 26.47+/-2.33 kg/m(2)) were included. Adiponectin concentrations in the patients were significantly lower than those in controls (4.71+/-2.11 microg/ml for patients, n=74; 15.95+/-3.72 microg/ml for controls, n=54; P<0.001). In the patients group there was a significant negative correlation between adiponectin and homeostasis model assessment index (r=-0.318, P=0.006 respectively). Plasma adiponectin concentrations in patients with proliferative diabetic retinopathy (n=20; 3.16+/-1.83 microg/ml) or non-proliferative diabetic retinopathy (n=24; 3.97+/-1.47 microg/ml, P=0.014) were significantly lower than those in patients without diabetic retinopathy (n=30; 6.30+/-1.57 microg/ml, P=0.001). When the presence of diabetes was defined as the final variable in the conditional logistic regression model with the adiponectin concentration as th...Continue Reading

Biomarkers for Type 2 Diabetes
Biomarkers can help understand chronic diseases and assist in risk prediction for prevention and early detection of diseases. Here is the latest research on biomarkers in type 2 diabetes, a disease in which the body is unable to produce or properly use insulin.
