Diabetic nephropathy shows a higher incidence in male subjects, which may in part be owing to genetic factors. The angiotensin II type 2 receptor (AT2), present in the renal glomerulus, may oppose the deleterious effects of the type I receptor (AT1) through vasodilatation and growth inhibition. We determined whether the functional intronic G1675A or A1818T polymorphism of the X-chromosomal AT2 gene is associated with blood pressure levels or with kidney function. We genotyped 996 (538 female/458 male subjects) Finnish patients with type I diabetes from the FinnDiane-study in a cross-sectional study. DNA samples were amplified using standard polymerase chain reaction protocol and the genotypes were determined by the minisequencing method. Male patients with the AA haplotype had a lower glomerular filtration rate (83 +/- 32 vs 94 +/- 34 ml min(-1) 1.73 m(-2), P = 0.008) and a higher pulse pressure (PP) (62 +/- 18 vs 57 +/- 15 mm Hg, P = 0.002; P < 0.05 after adjustment for age) than did those with the GT haplotype. No differences between the genotypes or haplotypes and these variables were evident in females. In males, the G1675A was also an independent variable in a linear regression analysis with PP (r(2) = 0.16, coefficient=3.64, s.e.m.=1.38, P < 0.01) as the dependent variable. These data suggest a gender-specific association between the AT2 gene and kidney function and premature aging of the arterial tree in patients with type I diabetes.

Diabetic nephropathy is the leading cause of end-stage renal disease (ESRD) in Japan and other Westernized countries. Over 50% of the ESRD patients die from cardiovascular events. Cardiovascular disease (CVD) in ESRD patients with diabetes mellitus (DM) are implicated in the endothelial dysfunction caused by hyperglycemia, hyperlipidemia, and hypertension, and in the vascular calcification of intimal and medial arterial blood vessels caused by hyperphosphatemia. Therefore, dietary control of hyperglycemia and hyperphosphatemia should play an important role in the management of ESRD patients with DM. Furthermore, recent findings suggest that high concentrations of serum phosphate, even if within the normal range, may be a risk factor for CVD and mortality. An in vivo study using klotho knockout mice and fibroblast growth factor 23 (FGF-23) knockout mice has revealed that correction of hyperphosphatemia and hypervitaminosis D could ameliorate the premature aging-like phenotype. A low glycemic index and low phosphate diet may provide an advantage in the prevention of aging-related diseases in healthy individuals as well as in those with chronic kidney disease.
