Abstract

To determine whether urinary albumin to creatinine ratio (Albumin index) and urinary N-acetyl-beta-D-glucosaminidase (NAG) to creatinine ratio (NAG index) in random spot urine samples can be sued to predict the early stage of diabetic nephropathy in the elderly non-insulin dependent diabetic patients, we measured these concentrations in 150 non-diabetics, 61 diabetics without retinopathy and 56 diabetics with retinopathy. All patients with Albustix-positive urine were excluded. Subjects divided into two groups according to whether they were < 60 years (adult group) or > or = 60 years old (old group). Multiple regression analysis was used to investigate the relationship between NAG index or Albumin index (dependent variable) and independent variables (age, systolic blood pressure, duration of diabetes. HbA1c) in diabetic patients. Diabetic patients with retinopathy showed the highest mean Albumin index, followed by diabetic patients without retinopathy and then non-diabetic patients both in adult group and in old group (p < 0.001, p < 0.001, respectively). Diabetic patients with retinopathy showed the highest mean NAG index, followed by diabetic patients without retinopathy and then non-diabetic patients both in adult group and ...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.
