Abstract: Objective To investigate the serum concentrations of connective tissue growth factor (CTGF) and serum cystatin C(CysC) in diabetic nephropathy(DN) patients and its clinical significance. Methods 82 cases of diabetic nephropathy patients were divided into three groups by urinary albumin excretion rate(UAER):normal al-buminuric group(group 1),microalbuminuric group(group 2),macroalbuminuric group(group 3). Serum concentra-tions of CTGF and CysC were determined by ELISA, which was compared with 20 cases of control group. Results CTGF and CysC were markedly higher in the three groups than that in healthy controls [CTGF: (87.65±6.09)、 (105.36±7.78)、(129.05±5.12) ng/L and (68.29±5.90) ng/L;CysC: (0.99±0.10)、(1.59±0.14)、 (2.53±0.27) mg/L and (0.82±0.56) mg/L, P<0.05]. CTGF, CysC were all positively correlated with UAER (r=0.80、0.21, P<0.05), all negatively correlated with glomerular filtration rate (eGFR) (r=-0.85、-0.88, P<0.01). Conclusions The serum concentrations of CTGF and CysC may be early markers in predicting diabetic nephropathy and assessing its severity.
