Impaired glycemic control is a potential predictor for macro- and microvascular complications of diabetes, which could be recognized by glycemic variability. The aim of this 10-year prospective cohort study presented here is to gain a better understanding of the correlation between GV and diabetic peripheral neuropathy (DPN) as one of the most common complications of T2DM.Since February 2010, 1152 adult patients with T2DM have been followed-up. Baseline features, anthropometric measurements, and laboratory findings were collected and documented during ten years. The association between DPN incidence and glycemic profile variability was evaluated using cox regression analysis. The coefficient of variation of glycemic indices within subjects was calculated and compared using an independent sample t-test.Individuals who developed neuropathy had significantly higher mean levels of glycemic indices (HbA1c, FBS, and 2hpp), urinary albumin excretion, mean creatinine levels, and a longer duration of diabetes. A significant positive correlation between incidence of DPN and glycemic profile variability (cv-FBS10 %, cv-FBS20 %, cv-2hpp20 %, cv-HbA1c5 % and cv-HbA1c10 %) was revealed. Results also showed that higher variability of FBS was associated with the higher risk of neuropathy incidence (HR: 12.29, p-value: 0.045), which indicates that glycemic profile variability is an independent risk factor for DPN in patients with T2DM.Variability of glycemic profiles from a visit to visit, regardless of sustained hyperglycemia, was indeed a significant risk factor for DPN in diabetic type 2 patients. CV-FBS was the most critical glycemic variability indices for DPN development.

Coronary heart disease (CHD) is a major mortality risk factor in patients with diabetes. LDL cholesterol (LDL-C) is a major risk factor for the development of atherosclerosis. There is one apolipoprotein B (ApoB) molecule in each LDL particle. We aimed to evaluate the predictive value of the LDL-C/ApoB ratio for CHD in patients with type 2 diabetes (T2D).In this case-cohort study (apo)lipoproteins and glycemic indices were measured in 1058 individuals with T2D from February 2002 to March 2019, with a median duration of follow up of 10 years. Of 1058 patients with T2D, coronary heart disease occurred in 242 patients. Increased waist circumference, waist-to-hip ratio, and hemoglobin A1c, low-density lipoprotein cholesterol (LDL-C)/Apolipoprotein B (ApoB) ratio, presence of hypertension and metabolic syndrome, and insulin and statin use were more prevalent among patients with CHD (P 0.001). Logistic regression analysis showed that an LDL-C/ApoB ratio equal or lower than 1.2 could predict CHD independent of ASCVD risk score [adjusted OR:1.841, CI:1.257-2.698, P 0.001] when adjusted for multiple confounders. The atherogenic index of plasma (AIP) did not predict CHD.This study showed that LDL-C/ApoB ratio, but not the atherogenic index of plasma, may be considered as an indicator of CHD independent of the ASCVD risk score in patients with T2D. This finding merits further clarification to optimize preventive strategies for CHD.

This study was designed to evaluate the meeting of ABC goals in patients with type 2 diabetes. The ABC goals were defined as meeting the HbA1c7%, systolic blood pressure130 mmHg and diastolic blood pressure80 mmHg, and LDL-C100 mg/dL. We also determined the associated factors with meeting the ABC goals, as well as the effectiveness of statin therapy.We designed a cross-sectional study of 2008 type 2 diabetes patients attending the diabetes clinics of Valiasr Hospital of Imam Khomeini Hospital Complex. Meeting ABC goals and their associated factors were analyzed from the registered data.At the end of the year 2014, 61.3% of patients met the HbA1c goal, which increased to 77.8% in 2017. Blood pressure of 79.5% of patients met the ADA recommendations by the end of the year 2014, reaching 86.6% in 2017. Moreover, 84.5% and 93.8% could reach the LDL-C goal in 2014 and 2017, respectively. The proportion for the patients meeting all three ABC goals were 23.2% and 42.1% in 2014 and 2017, respectively.The level of achievement of ABC goals in Iran is lower than expected and it requires a lot of programming effort and follow-up. As patients are followed over the years, controlling ABC becomes much more favorable.

Background Type 2 diabetes mellitus (T2DM) is associated with an oxidative milieu that leads to increased lipid peroxidation. Main focus of this study was to understand levels and correlations of two oxidative stress indices, malondialdehyde (MDA) and oxidized low-density lipoprotein (ox-LDL) levels, in diabetes associated oxidative stress. Moreover we examined the impact of different HDL-C levels on this correlation. Material and methods A total of 151 patients with T2DM and 45 healthy adults were enrolled in this cross-sectional study. Fasting plasma glucose, total cholesterol, triglyceride, High-Density Lipoprotein (HDL C), low-density lipoprotein (LDL), ox-LDL and MDA were measured. Results Linear regression analysis revealed higher levels and a positive correlation between MDA and ox-LDL in patients with T2DM (p 3.57 nmol/ml and ox-LDL > 60.68 U/dl had significantly poorer lipid profile and diabetic nephropathy indices. Patients were stratified into four quartiles based on associated HDL levels. Ox-LDL and MDA showed significant positive correlation only in HDL levels below 35 mg/dl. Conclusions We attempted to investigate applicability of MDA and ox-LDL in predicting T2DM related oxidative stress. Present data strongly suggest that using both of MDA and ox-LDL increases their specificity in predicting oxidative milieu and diabetic nephropathy. Moreover, we showed that HDL levels above 35 mg/dl might have beneficial effect on oxidative reactions.

Background Albuminuria is one of the first asymptomatic clinical manifestations of microvascular damage in type 2 diabetes. High-sensitivity C-reactive protein (hs-CRP), Asymmetric dimethylarginine (ADMA), and nitric oxide (NO) are important risk factors for endothelial dysfunction. The aim of this study is to evaluate hs-CRP, ADMA, and NO levels and their correlations in patients with type 2 diabetes respect to their albuminuric states. Methods We quantified serum hs-CRP, ADMA, and NO levels in 40 microalbuminuric (urinary albumin excretion ≤ 30 mg/day and Results The mean value of albuminuria was 238 ± 58 mg/day in the microalbuminuric group and 12.6 ± 4.7 mg/day in the normoalbuminuric group. Creatinine was significantly higher and GFR was significantly lower in group with microalbuminuria than normoalbuminuria (p Conclusion Hs-CRP was higher in microalbuminuric patients with type 2 diabetes compare to normoalbuminuric group. Also we found changing association among ADMA, NO and hs-CRP from normoalbuminuric to albuminuric state which this finding may be linked to the role of basic inflammation in confounding some interactions and creating some new ones.

Diabetes is associated with the excess formation of advanced glycation end-products (AGEs) and advanced oxidation protein products (AOPP), and low levels of ferric reducing ability of plasma (FRAP). However, the trend of oxidative and antioxidant markers levels according to diabetes duration is unclear.In a case-control study, 240 patients with diabetes and 100 healthy controls were enrolled. Patients were divided into four groups according to the duration of diabetes, including newly diagnosed, 1-5, 5-10, and 10-15 years. Serum AGEs, AOPP, and FRAP levels were compared among groups.AGEs and AOPP were higher and FRAP was lower in patients with diabetes compared to healthy controls. Serum levels of AGEs increased progressively with increasing in diabetes duration. AGEs levels were 68.97 ± 7.28% in newly-diagnosed, 73.43 ± 12.96% in 1-5 years and 80.44 ± 13.84% in 10-15 years of diabetes duration (pairwise p-values0.05). In linear regression analysis the correlation among AGEs, AOPP, FRAP, and diabetes duration remained significant after adjustment for age, BMI, HDL, HbA1c, waist circumference, microvascular complications, and coronary artery diseases. ROC analysis showed AGEs could predict the duration of diabetes when patients with 10-15 years duration of diabetes were compared to patients with 1-5 years duration of diabetes (AUC = 0.676, p-value = 0.003).Diabetes promotes AGEs, and AOPP production, independent of glycemic control and patients age. Serum levels of AGEs increase progressively with increasing duration of diabetes. AGEs may be helpful in estimating chronicity of diabetes.
