    Abstract:
    Tissue macrophage accumulation is thought to induce insulin resistance during obesity and stimulate the progression of diabetic nephropathy (DN). The objective of this study was to investigate genotypic and allelic frequencies of monocyte chemoattractant protein-1 (MCP-1) gene polymorphism in the healthy and patients with and without DN. The MCP-1 genotypes were determined in 43 patients with nephropathy and 43 without nephropathy and a control group of 105 healthy individuals. The genotype MCP-1 (-2518G/A) distribution did differ between the control group and the type 2 diabetic patients (P = 0.004). The frequency of the polymorphic G allele was also no similar for the group with type 2 diabetes as for the control group with 20.9 and 32.4%, respectively (P = 0.012). The AA genotype and A allele at MCP-1 -2518 was an independent risk factor for the progression of type 2 diabetes. In conclusion, MCP-1 AA genotype and A allele may play a specific role(s) in determining diabetic susceptibility, but do not seem to be important in the clinical manifestations of DN.
