Abstract
OBJECTIVE: Diabetic nephropathy is a major diabetes complication. Arterial resistance index (RI) may predict deterioration in kidney function. This study was designed to compare renal arterial RI in different stages of renal function according to glomerular filtration rate (GFR), serum creatinine level and proteinuria.
MATERIALS AND METHODS: In a cross-sectional study on 81 diabetic patients in three groups (Without albuminuria, with microalbuminuria, with macroalbuminuria), pulsatile Doppler ultrasonography was performed to measure intra-renal arterial resistance index and find the association of this parameter with features of diabetic nephropathy. Data was analyzed using SPSS (ver. 16).
RESULTS: Serum creatinine, GFR and proteinuria were significantly different among three groups. RI was highest in the group with macroalbuminuria and the difference among three groups was statistically significant. (P value<0.001) RI was correlated with serum creatinine, GFR and proteinuria.
CONCLUSION: Higher RI correlates with higher proteinuria in diabetic patients.

Abstract
Objective: An association between high homocysteine levels and proteinuria in diabetic nephropathy has been shown. On the other hand, supplementation with folic acid lowers homocysteine concentration. We have studied the effects of folic acid supplementation on proteinuria in type 2 diabetic patients with overt proteinuria.
Materials and Methods: Forty five (29 men and 16 women) type 2 diabetic patients with overt proteinuria were randomized into 2 groups. One group was treated with folic acid for 6 months (22 patients), and the other was not (control group, 23 patients). Twenty-four hours proteinuria, creatinine clearance, and serum homocysteine were measured at baseline and 6 months of treatment.
Results: In the treatment group, baseline proteinuria was 2927 ± 2858 mg/day, and after 6 months of folic acid treatment, there was a significant decrease in proteinuria to 2049 ± 1641 mg/day (P < 0.05). For the control group, there was no change of proteinuria after 6 months of follow-up ( P = 0.9). Serum homocysteine levels were significantly decreased in subjects treated with folic acid, from 19.2 ± 9.46 µmol/L to 16 ± 5.6 µmol/L P < 0.05). There were no significant differences in creatinine clearance at the end of the study comparing the two groups.
Conclusion: Supplementation with folic acid decreases proteinuria in type 2 diabetic patients with overt proteinuria and that this action may be mediated through reduced concentrations of serum homocysteine. However, for evaluation of the effect of folic acid on renal function, further studies with longer follow-up are needed.

Abstract
Objectives: Interruption of rennin-angiotensin-aldosterone system has become a leading therapeutic strategy in the treatment of diabetic nephropathy however, ACEIs and ARBs do not uniformly suppress the rennin-angiotensin-aldosterone system. Plasma aldosterone levels are elevated in a group of patients despite therapy and this phenomenon known as aldosterone escape or aldosterone break through.
Materials and Methods: Forty-two type 2 diabetic patients with overt proteinuria were randomized into two groups and according to double-blind case-control study, one group was treated with spironolactone and others were treated with placebo for 4 months. Twenty-four hours urine protein, glomerular filtration rate (GFR) and blood pressure were measured at baseline and after 4 months of treatment. Serum potassium was checked at baseline and one month of treatment.
Results: Urine protein decreased in case group by 26.5% at the end of 4 months, but increased in control group by 17.9% (P=0.003). GFR did not have any significant change in case group (P<0.354), but decreased in case group significantly (P<0.001).
Conclusion: Our study showed that spironolactone 12.5 mg/day is safe (without hyperkalemia and gynecomastia) and effective to decrease proteinuria in diabetic patient with CKD1-2.

Abstract
Objective: In patients with diabetes mellitus, increased rate of lipoprotein oxidation and oxidative stress have important role in diabetic angiopathy, including nephropathy. We designed a study for comparing the level of Ox-LDL in diabetic patients with Macro-albuminuria, Micro-albuminuria, versus Normo-albuminuric.
Materials and Methods: One hundred and thirty five patients with type 2 diabetes mellitus who had been referred to the Yazd Diabetes Clinic, from 1391 through 1392, were enrolled to our study. The 24 hours urinary albumin excretion was measured and Macro-albuminuria defined as albumin excretion of greater than 300mg per day and below 30mg per day in normo-albuminuric group and between 30-300mg defined as Micro-albuminuria group. Plasma level of OX-LDL was measured.
Results: The plasma OX-LDL level in patients with Macro-albuminuria was higher than those in Normo-albuminuric group, (16.1±3.6 U/ml versus 8.6±1.7 U/ml). There was a significant correlation between the OX-LDL and urine albumin in Macro-albuminuria and Micro-albuminuria groups. There was no significant correlation between the OX-LDL and HbA1C level and diabetes duration.
Conclusion: Significantly elevated plasma OX-LDL in patients with Macro-albuminuria suggests that OX-LDL may play an important role in the progression of diabetic nephropathy.

Abstract
Objective: Atorvastatin has the pleiotropic effects, including anti-inflammation and antioxidant. Therefore, this study considered to examine the effects of atorvastatin on NF-қB expression, as a main transcription factor for expression of inflammatory cytokines, in hyperglycemia-induced nephropathy in rat.
Materials and Methods: Twenty four male Wistar rats were randomly divided into four groups; Normal, Normal treatment, Diabetic, and Diabetic treatment. Rats were made diabetic by an intravenous injection of streptozotocin (40 mg/kg). Treated rats received atorvastatin for 60 days (40 mg/kg/day). At the end of experiment, blood samples were collected for measurement of blood glucose. Moreover, the mRNA expression level of NF-қB in kidney was determined by RT-PCR technique.
Results: Induction of diabetes significantly increased the mean value of blood glucose in diabetic rats (>450 mg/dl) compared with normal rats (P=0.001). Chronic hyperglycemia also increased the mRNA expression level of NF-қB in diabetic kidney. Moreover, the mean value of kidney index was significantly increased in diabetic rats compared to normal group (P=0.001). Treatment with atorvastatin in diabetic rats for 60 days reduced the mRNA expression level of NF-қB and kidney index compared to non-treated diabetic rats (P=0.014).
Conclusion: Our findings revealed that atorvastatin is able to prevent the development of diabetic nephropathy during chronic uncontrolled hyperglycemia possibly by the inhibition of NF-қB expression in the kidneys of diabetic rats.

Abstract
Objective: Oxidative stress plays an important role in the onset and progression of diabetic nephropathy. So antioxidant agents may be one of the key treatment strategies for prevention of diabetic nephropathy progression .The aim of this study was to determine the effect of selenium (Se) on micro-albuminuria in type 2 diabetic (T2DM) patients.
Materials and Methods: This study was a clinical study on 60 T2DM patients with micro-albuminuria who were referred to Yazd diabetic research center from March 2016 till April 2017. Patients were randomized in to two groups: Se (200 microgram Se daily) and control. The control group did not receive placebo. The intervention duration was 12 weeks. Micro-albuminuria, fasting blood sugar (FBS), cholesterol, triglycerides, HDL-C, LDL-C, urea, creatinine, HbA1c, plasma Se concentration were measured at the baseline and after 12 weeks.
Results: Micro-albuminuria decreased after 12 weeks in both studied groups but it was not statistically significant. Cholesterol and LDL levels improved statistically in both studied groups at the end of study (P-value: 0.034, 0.023 respectively). Plasma Se level increased in intervention group (P-value< 0.001). There were clinically improvement in other studied variables after 12 weeks in two studied groups but not statistically significant
Conclusion: Our study demonstrated that Se supplementation for 12 weeks among patients with micro-albuminuria had no beneficial effects on micro albuminuria.

Abstract
Objective: Circulating endothelial progenitor cells (EPCs) play an essential role in endothelial repair and neovascularization. Vitamin D deficiency may contribute to EPC depletion and endothelial dysfunction in patients with type 2 diabetes. In addition, iron overload is closely related to the development of diabetes and its various chronic complications. This study was designed to determine the relationship between EPC markers (CD34, CD133), vitamin D, and iron in patients with diabetic nephropathy.
Materials and Methods: This case-control study was conducted on 67 diabetic patients with or without nephropathy. Blood pressure and all biochemical parameters were measured and compared. Serum concentrations of insulin, vitamin D, CD34, and CD133 were measured using ELISA. Serum iron concentration was measured using atomic absorption spectrometry.
Results: Body mass index (P= 0.006), diastolic pressure (P= 0.018), insulin level (P= 0.028), Creatinine (P= 0.013), duration of diabetes, uric acid, and glomerular filtration rate (GFR) were significantly different between the two groups (each P= 0.0001).The vitamin D (P= 0.034), CD34 (P= 0.0001), and CD133 (P= 0.025) levels decreased, and Iron (P= 0.0001) increased in the case group. Also, CD34 has a significant direct relationship with insulin, insulin resistance, and CD133. The results showed that vitamin D, iron, CD34, and CD133 had a significant relationship with the severity of nephropathy (P= 0.0001, each).
Conclusion: Increased iron levels and decreased vitamin D, CD34, and CD133 levels are associated with the severity of nephropathy. This result indicates that diabetic nephropathy may directly reduce CD34 and CD133 levels in the body, increasing the incidence of secondary complications in these patients.
