摘要

Diabetic nephropathy (DN) is characterized structurally by progressive mesangial deposition of extracellular matrix (ECM). Transforming growth factor-? (TGF-?) is considered to be one of the major cytokines involved in the regulation of ECM synthesis and degradation. Several studies suggest that an increase in urinary TGF-? levels may reflect an enhanced production of this polypeptide by the kidney cells. We evaluated TGF-? in occasional urine samples from 14 normal individuals and 23 patients with type 2 diabetes (13 with persistent proteinuria >500 mg/24 h, DN, 6 with microalbuminuria, DMMA, and 4 with normal urinary albumin excretion, DMN) by enzyme immunoassay. An increase in the rate of urinary TGF-? excretion (pg/mg UCreat.) was observed in patients with DN (296.07 ± 330.77) (Pa = 0.05) (Pearson's analysis), one of the parameters of disease progression.
