Diabetes is now the major cause of end-stage renal failure worldwide, both in developing and in developed nations. Hyperglycemia is still considered the principal cause of complications of diabetes because of the formation of sugar-derived substances called advanced glycation end products. The formation of advanced glycation end product is markedly accelerated in diabetes because of the increased availability of glucose. The receptor for advanced glycation end products (RAGE) has been shown to be involved in the pathogenesis of diabetic complications. The aim of this work was to assess the possible association between soluble receptor for advanced glycation end products (sRAGE) and urinary albumin excretion in type 2 diabetic patients as an early predictor of microvascular complications such as diabetic nephropathy. The present study was carried on 70 individuals: 10 healthy individuals as control, 20 diabetic patients with normoalbuminuria, 20 diabetic patients with microalbuminuria, and 20 diabetic patients with macroalbuminuria. All participants were subjected to estimation of sRAGE by the sandwich enzyme-linked immunosorbent assay technique together with routine laboratory investigations. The results of this study showed that all diabetic patients had a low level of serum RAGE compared with the control group. Furthermore, a characteristic trend was observed whereas three groups of diabetic patients showed a decrease in RAGE in parallel with the severity of renal involvement. From this point of view, stimulation of sRAGE production should be considered a potential therapeutic target in diabetic patients.
