TODO - Background: The aim of the present study was to evaluate the role of extracellular matrix-associated glycosaminoglycans (GAGs), connective tissue growth factor (CTGF), angiogenic vascular endothelial growth factor (VEGF) and inflammatory factors (MCP-1, CD40, IFN-γ) in the development of diabetic nephropathy in type 1 diabetes (T1DM). Methods: Plasma and urine samples from 30 T1DM patients and 20 healthy controls were used to measure the levels of CTGF, VEGF, MCP-1, CD40 and IFN-γ by ELISA. Plasma and urine GAGs were measured using a spectrophotometric method. Results: Plasma levels of GAGs, CD40 and MCP-1 and urine levels of GAGs and CTGF were significantly elevated in normoalbuminuric T1DM patients. A tendency to higher plasma VEGF levels was found in patients compared to controls. The urine/plasma GAGs ratio of T1DM patients was almost similar to that of healthy subjects (HS), whereas the urine/plasma CTGF ratio was about three times greater in diabetic patients compared to HS. Conclusions: Conclusively, increased GAGs and CTGF excretion are evident in T1DM normoalbuminuric juveniles, possibly reflecting early renal injury signs, before the initiation of albuminuria. © 2011 by Walter de Gruyter.
