Abstract
Background. Monocyte chemoattractant protein-1 (MCP-1) can directly elicit an inflammatory response by inducing cytokine and adhesion molecule expression in the kidney. We investigated the role of MCP-1 in the development of early nephropathy in patients with type-1 diabetes mellitus, in addition to the effect of high-dose vitamin E treatment (8 weeks) on early stages of diabetic nephropathy. Methods. This study was carried out on 30 type-1 diabetic patients subdivided into two equal groups according to their urinary albumin excretion, in addition to 10 healthy matched volunteers included as controls. MCP-1, glycated hemoglobin (HbA1c), and albuminuria—before and after vitamin E treatment—were measured in all studied groups. Results. Serum MCP-1 and HbA1c were significantly elevated in patients with microalbuminuria and poor glycemic control (
