We investigated the relationship between BsmI/ApaI polymorphisms in vitamin D receptor gene and diabetic nephropathy in a Han Chinese population. PCR-restriction fragment length polymorphism was used to test the genotype and allele frequency of BsmI and ApaI polymorphisms in 304 patients with type 2 diabetes mellitus (DM group) and 100 control individuals (ND group). The DM group was further divided into DN0 (no diabetic nephropathy), DN1 (diabetes with small amount of albuminuria), DN2 (diabetes with large amount of albuminuria), L/NDN (late-onset DN after 5 years/no DN over the whole follow-up period of 5 years) and EDN (early-onset diabetic nephropathy occurring within first year) subgroup. We found that (1) genotype and allele frequency of BsmI polymorphism had significant difference between DM and ND group; BB+Bb genotype and B allele frequency were significantly higher in DN2 group than in ND and DN0 group; the ApaI polymorphism and allele frequency did not show any difference between DM and ND group; (2) BsmI BB+Bb genotype and B allele frequency were significantly higher in EDN group than in L/NDN group; (3) among patients with nephropathy, albumin excretion rate (AER) in 24-hour urine was significantly higher in those with BB+Bb phenotype than in those with bb phenotype (P<0.01), (4) unconditional logistic regression analysis showed that BsmI BB+Bb genotype was not only correlated with type 2 diabetic nephropathy, but also correlated with early-onset type 2 diabetic nephropathy. We conclude that the allele B (BB or Bb genotype) in vitamin D receptor gene is correlated with large amount albuminuria in the Han Chinese population with type 2 diabetes, and is probably a risk factor for early-onset diabetic nephropathy.

Diabetic nephropathy (DN) is a major cause of end-stage kidney disease, and therefore early diagnosis and intervention may help reverse renal damage. One hundred and sixty-eight patients with T2DM and 56 healthy volunteers (control group) were enrolled at Shandong University Qilu Hospital between April 2010 and October 2012. All subjects underwent blood sampling for sera homocysteine (Hcy) and cystatin C (Cys C) assays and a urine microalbumin test. The patients were divided into three groups according to the urine microalbumin excretion rate (UMAER): the simple DM group (SDM group, n = 51), the early-stage DN group (EDN group, n = 60), and the clinical DN and renal failure group (CDN group, n = 57). Correlation analysis was performed to examine the association between sera Hcy and Cys C levels with UMAER. Our findings showed that sera Hcy level, Cys C level, and UMAER increased significantly in the SDM group (P < 0.05, P < 0.01), the EDN group (P < 0.01), and the CDN group (P < 0.01) as compared with the control group. These three biochemical markers also increased significantly with DN progression (P < 0.01). Correlation analysis showed that sera Hcy and Cys C levels were positively correlated with UMAER (r = 0.702, P < 0.01; r = 0.873, P < 0.01). In conclusion, our results showed that sera Hcy and Cys C levels increased consistently with the development and progression of DN as indicated by UMAER. Sera Hcy and Cys C are sensitive biomarkers for the detection of early-stage DN and monitoring its progression.
