Oxidative stress markers in plasma and urine of prepubertal patients with type 1 diabetes mellitus.

Markers of oxidative stress were studied in plasma and urine of prepubertal patients with type 1 diabetes mellitus (DM1) with less than 5 years of disease (n = 27). The results were compared to healthy, age- and sex-matched control children (n = 27). Oxidative stress parameters evaluated included advanced oxidation protein products (AOPP), total peroxyl radical-trapping antioxidant parameter (TRAP), and F2-isoprostanes (8-epi-prostaglandin-F2: 8-isoPGF2alpha). No statistically significant differences were found for any of the oxidative stress markers assessed between patients with DM1 and controls. In addition, weight, height, and routine metabolic tests, including creatininemia and cholesterol levels, were similar between the groups. The lack of significant differences between healthy controls and patients with DM1 suggests that treatment is able to counteract the increase in free radical production.

[Autoantibodies against advanced glycation products in patients with type 1 diabetes mellitus].

BACKGROUND: Advanced glycation end products are associated with chronic complications of diabetes mellitus. This glycation process renders many proteins immunogenic. AIM: To detect the presence of antibodies against albumin, collagen and low density lipoprotein glycation products in boys and teenagers with diabetes mellitus. PATIENTS AND METHODS: Thirty one patients with diabetes mellitus type I, aged 11 +/- 3.8 years and with a mean duration of disease of 3.7 +/- 2.7 years and 31 healthy controls aged 12.4 +/- 5.3 years were studied. Antibodies against glycation end products were detected by ELISA and results were expressed as a ratio of the optical density of the glycated protein/optical density of the native protein. RESULTS: Diabetic patients and healthy controls did not have antibodies against albumin glycation end products. Diabetics had higher levels of antibodies than controls for collagen glycation end products (2.6 +/- 0.4 and 1.8 +/- 0.2 respectively, p < 0.01) and low density lipoprotein glycation end products (3.07 +/- 0.92 and 2.2 +/- 0.72 respectively, p < 0.05). CONCLUSIONS: The biological role of these antibodies is not clear. They could be a depuration mechanism for glycation end products or contribute to chronic complications of diabetes mellitus.

[Prevalence of celiac disease in diabetic children and adolescents].

BACKGROUND: Celiac disease is more common in patients with insulin dependent diabetes than in the general population. AIM: To detect celiac disease in diabetic children and adolescents. PATIENTS AND METHODS: IgA antigliadin, IgG antireticulin and IgG antiendomysium antibodies were measured in 67 diabetic children (35 female), aged between 4 and 18 years old. RESULTS: Only one male adolescent, aged 18 years old, without gastrointestinal symptoms, had a significant elevation of antireticulin and antiendomysium antibodies. His intestinal biopsy showed subtotal villous atrophy, consistent with celiac disease. CONCLUSIONS: The prevalence of celiac disease in these diabetic children is 1:67 (1.5%). Similar figures have been reported elsewhere.

[Persistent microalbuminuria in insulin-dependent diabetics and cardiovascular risk factors].

A possible association of cardiovascular risk factors and early diabetic nephropathy was investigated in 32 patients. Microalbuminuria (radioimmunoassay), total and HDL cholesterol and triglycerides (enzymatic methods), glycosylated hemoglobin (colorimetric methods), Apo A1 and B (immunonephelometric) and LDL were measured. Microalbuminuria was present in 28% of patients. Compared to subjects with no microalbuminuria they had increased levels of cholesterol (200.2 +/- 13.5 (SE) vs 168.6 +/- 9.4 mg/dl, p < 0.025) and LDL cholesterol (171.9 +/- 14.1 vs 137.4 +/- 9.1 mg/dl, p < 0.025). Systolic blood pressure was also higher in patients with microalbuminuria (127.8 +/- 3.9 vs 114.5 +/- 2.8 mmHg, p < 0.01). Microalbuminuria was correlated to the level of diastolic blood pressure (r = 0.74, p < 0.025). Thus, persistent microalbuminuria in insulin dependent diabetic patients is associated to cardiovascular risk factors which may explain the increased cardiovascular morbidity and mortality in these patients.
