Malondialdehyde and Pentosidine in Young Type 1 Diabetic Patients

Abstract

Objective: To investigate whether advanced glycosylation end products (AGE) and oxidative stress are augmented in young patients with type 1 diabetes at early clinical stages of the disease. Patients and Methods:The study included 50 patients with type 1 diabetes among those attending the endocrine clinic in National Research Centre and 30 healthy volunteers in the control group. Serum glucose, total cholesterol, low-density lipoprotein cholesterol (LDL-c), high-density lipoprotein cholesterol (HDL-c), triglycerides, serum creatinine concentrations, glycosylated hemoglobin (HbA1c), urinary albumin/ creatinine ratio, malondialdehyde and pentosidine were assessed.Results: No significant difference was found between age of patients (12.0 ± 3.2 ) and controls (11.0 ± 1.2), P > 0.05. Blood glucose, HbA1c, urinary albumin / creatinine ratio, pentosidine and malondialdehyde were significantly higher in diabetic patients than controls. Pentosidine and malondialdehyde had a significant positive correlation with blood glucose, HbA1c and urinary albumin/creatinine ratio.
