Serum Levels of Antibodies to Advanced Glycation End Products in Patients with Type 2 Diabetes Mellitus and Hypertension.
Proteins containing advanced glycation end products are highly immunogenic and anti-advanced glycation end products antibodies (anti-AGEs antibodies) are found in the sera of diabetics.. Enzyme-linked immunosorbent assay (ELISA) was used for measuring levels of anti-advanced glycation end products antibodies in sera of 93 patients with type 2 diabetes mellitus and arterial hypertension (mean age 61.4±11.3 years, diabetes duration 9.88±3.12 years; hypertension duration 9.28±4.98). These values were compared to serum anti-AGEs antibodies in 42 age and sex matched controls. Diabetics were divided in two groups according to presence or absence of microangiopathy, group 1 (n=67) and group 2 (n=26), respectively.. Serum levels of anti-AGEs antibodies in patients with type 2 diabetes mellitus and arterial hypertension were statistically significantly higher than those in the control group (1.39±0.39 vs. 1.05±0.32), (p<0.05). Group 1 showed significantly higher levels of anti-AGEs antibodies than those of healthy controls (1.53±0.14 vs. 1.05±0.32), (p<0.01). Anti-AGEs antibodies levels were higher in patients with microvascular complications than these in patients without complications. Anti-AGEs antibodies correlate with diastolic blood pressure (r=0.26, p=0.05) and body mass index (r=0.37, p=0.03). We found significantly higher percentage of positive patients for anti-AGEs antibodies (mean+2SD) in group 1 than in group 2.. Determining the levels of serum anti-AGEs antibodies can help physicians make early diagnosis and prognosis of the severity of late diabetic complications in hypertensive patients.

Genetic predisposition to albuminuria is associated with increased arterial stiffness: role of elastin.
The Munich Wistar Frömter (MWF) rat strain represents an experimental model to study cardiovascular alterations under conditions of progressive albuminuria. The aim of this study was to evaluate the association between genetic predisposition to albuminuria and the development of arterial stiffness and/or vascular remodelling.. Experiments were performed in mesenteric arteries from 12-week-old MWF, Wistar Kyoto (WKY) and consomic MWF-6(SHR) and MWF-8(SHR) rats in which chromosomes 6 or 8 associated with albuminuria from MWF were replaced by the respective chromosome from spontaneously hypertensive rats (SHR).. Incremental distensibility, wall stress and strain were reduced, and arterial stiffness was significantly increased in albuminuric MWF compared with WKY. Albuminuria suppression in both consomic strains was associated with lower β-values in MWF-8(SHR) and MWF-6(SHR) compared with MWF. Moreover, elastin content was significantly lower in MWF external elastic lamina compared with WKY and both consomic strains. In addition, a reduction in arterial external and internal diameter and cross-sectional area was detected in MWF compared with WKY, thus exhibiting an inward hypotrophic remodelling. However, these alterations remained unchanged in both consomic strains.. These data demonstrate that albuminuria in MWF is associated with increased arterial stiffness due to a reduction of elastin content in the external elastic lamina. Moreover, inward hypotrophic remodelling in MWF is not directly associated with albuminuria. In contrast, we demonstrated that two major genetic loci affect both the development of albuminuria and arterial stiffness, thus linking albuminuria and impairment of mechanical properties of resistance arteries.
