Abstract
BACKGROUND In this study, we evaluate the association between triglyceride to high-density lipoprotein cholesterol (TG/HDL) ratio and total cholesterol (TC) to HDL (TC/HDL) ratio and the risks of type 2 diabetes (T2D) in an Iranian high-risk population. METHODS We analysed 7-year follow-up data (n = 1771) in non-diabetic first-degree relatives of consecutive patients with T2D 30-70 years old. The primary outcome was the diagnosis of T2D based on repeated oral glucose tolerance tests. We used Cox proportional hazard models to estimate hazard ratio for incident T2D across tertiles of TG/HDL and TC/HDL ratios and plotted a receiver operating characteristic (ROC) curve to assess discrimination. RESULTS The highest tertile of TG/HDL and TC/HDL ratios compared with the lowest tertile was not associated with T2D in age- and gender-adjusted models (HR 0.99, 95% CI: 0.88, 1.11 for TG/HDL ratio and 1.10, 95% CI: 0.97, 1.23 for TC/HDL ratio). Further adjustment for waist circumference or body mass index, fasting plasma glucose, and low-density lipoprotein cholesterol did not appreciably alter the hazard ratio compared with the age- and gender-adjusted model. The area under the ROC curve for TG/HDL ratio was 57.7% (95% CI: 54.0, 61.5) and for TC/HDL ratio was 55.1% (95% CI: 51.2, 59.0). CONCLUSIONS TG/HDL and TC/HDL ratios were not robust predictors of T2D in high-risk individuals in Iran. Copyright © 2015 John Wiley & Sons, Ltd.

Abstract
BACKGROUND Hydroxychloroquine can improve most underlying coronary risk factors; however, there are a few studies on the effects of hydroxychloroquine on blood glucose and insulin resistance. The current study aimed to assess the effects of hydroxychloroquine on blood glucose control status as well as on level of lipid profile and inflammatory biomarkers in prediabetic patients. MATERIALS AND METHODS In a randomized, double-blinded, controlled trial, 39 consecutive patients who were suffering from prediabetes and were referred to the Isfahan Endocrinology Center in January 2013 were randomly assigned to receive hydroxychloroquine (6.5 mg/kg/day) (n = 20) or placebo (n = 19) for 12 weeks. The biomarker indices and anthropometric parameters were tested before and after completion of treatment. RESULTS In both groups of patients receiving hydroxychloroquine and placebo, except for serum level of insulin that was significantly elevated after treatment by hydroxychloroquine, the changes in other parameters remained insignificant. Both groups experienced increase of insulin level, but this change was considerably higher in those groups receiving hydroxychloroquine. The group receiving hydroxychloroquine experienced reduction of glucose at 60 min of Oral Glucose Tolerance Test (OGTT) test after intervention, while the placebo group experienced increase of blood glucose at the same time. CONCLUSION The use of hydroxychloroquine may increase the serum insulin level in patients with prediabetic states who are at risk of developing diabetes mellitus.

Abstract
AIMS To evaluate the association of type 2 diabetes risk in first-degree relatives of diabetics with waist and hip circumference (WC and HC) and waist-hip ratio (WHR). METHODS We retrieved the data of 1319 subjects who had at least two visits during 2003-2010 and had been examined for diabetes status, WC and HC. Joint survival-longitudinal analysis and Cox regression were performed and the results were compared. RESULTS There was a significant direct relationship between diabetes risk and WC and WHR. The risk increased by 23% (95% CI: 5%-38%) and by 28% (95% CI: 9%-58%) respectively, for every 10cm increase in WC and 10% increase in WHR. Post-hoc subgroup analysis showed that these findings were present in females, but not in males. No significant association was seen for HC. Simple Cox regression showed direct association with WC and HC and no association with WHR. CONCLUSIONS In addition to dependence on measurement time, results from Cox model were inconclusive. The joint model showed a direct effect of WC and WHR albeit weaker than those in the general population, suggesting the possibility that factors other than the obesity indices are playing a stronger role in the elevated risk in this population. Multivariate models are needed for shedding light on the association.

Abstract
N, N-dimethyl N-ethyl chitosan (DMEC), a quanternized derivative of chitosan was synthesized based on a modified two-step method via a 22 factorial design to optimize the preparative conditions. The degree of deacetylation of the starting chitosan was determined by FTIR and NMR methods and was 95%. In the first step of the synthesis, mono-ethyl chitosan was prepared by introducing an ethyl group onto the amine group of chitosan via a Schiff base and in the next step methyl iodide was added to produce DMEC which was water soluble in a pH range of 4-8. The DMEC polymers with different degrees of quaternization were obtained and fully characterized using FTIR and 1H-NMR spectroscopic methods. Based on 1H-NMR calculations, the degree of quaternization was 52% by optimizing the two-step process.

Abstract
Chitosan exhibits poor solubility at pH values above 6 which prevents its enhancing effects at drugs absorption of sites. In the present work, N-triethylated chitosan (TEC) was prepared based on a modified one-step process via a 22 factorial design to optimize the preparative conditions. TEC polymer with different degree of quaternization for pharmacological and pharmaceutical experiments was achieved. Ethyl iodide and sodium hydroxide concentrations were chosen as independent variables. The degree of deacetylation of the starting chitosan was predetermined by pH-metric titration, infrared, and NMR methods. TEC chloride was fully characterized using FTIR and 1H-NMR spectroscopies. Based on NMR calculations, a high degree of quaternization was achieved through the optimized one-step process. These highly N-triethylated chitosan chlorides were soluble in water at room temperature.

Abstract
BACKGROUND In Asian population, diabetes mellitus is increasing and has become an important health problem in recent decades. In Iran, cardiovascular disease (CVD) accounts for nearly 46% of the total costs spent for diabetes-associated diseases. Because individuals with diabetes have highly increased CVD risk compared with normal individuals, it is important to diagnosis factors that may increase CVD risk in diabetic patients. The study objective was to identify predictors associated with CVD mortality in patients with type 2 diabetes (T2D) and to develop a prediction model for cardiovascular (CV)-death using a competing risk approach. MATERIALS AND METHODS The study population consisted of 2638 T2D (male = 1110, female = 1528) patients aged ≥35 years attending from Endocrine and Metabolism Research Center in Isfahan for a mean follow-up period of 12 years; predictors for different cause of death were evaluated using cause specific Cox proportional and subdistribution hazards models. RESULTS Based on competing modeling, the increase in blood pressure (BP) (spontaneously hypertensive rats [SHR]: 1.64), cholesterol (SHR: 1.55), and duration of diabetes (SHR: 2.03) were associated with CVD-death. Also, the increase in BP (SHR: 1.85), fasting blood sugar (SHR: 2.94), and duration of diabetes (SHR: 1.68) were associated with other death (consist of cerebrovascular accidents, cancer, infection, and diabetic nephropathy). CONCLUSIONS This finding suggests that more attention should be paid to the management of CV risk in type 2 diabetic patients with high cholesterol, high BP, and long diabetes duration.

Abstract
BACKGROUND Diabetes mellitus is a chronic disease which many factors are involved and is developing considerably worldwide. Increasing aging population and obesity in the societies has improved the scale of the type 2 diabetes significantly. The aim of this study was to determine the direct medical costs of outpatient cares of diabetes in Iran. METHODS Active patients of Isfahan Endocrinology and Metabolism Research Center (IEMRC) by the end of March 2011 were employed for data extraction. Type 2 diabetics were classified into 4 groups based on their therapeutic regimens. Type and frequency of health care services were extracted from the patients' profiles manually. The incidence of major diabetes complications were also examined from the subjects' profiles. The numbers of services used by the patients in different treatment groups were multiplied by the desired medical tariffs to calculate the direct medical costs. RESULTS 2898 number of cases was reviewed in this study; 63.8 % women and 36.2% men. 4.3% of the patients were placed group I; 50.1% in group II, and 34.6% and 11% in groups III and IV respectively. The age distribution of the patients varied widely from 30 to 90 years; 5.8% between 30 and 39 years, 62.3% between 40 and 59, and 31.9% at 60 and over. Nephropathy (72.4%), and neuropathy (39%) were the most frequent adverse effect between the type 2 diabetics in Isfahan. The group III with spending $192.3 in total was absorbed the highest amount of the resources between the patients' groups. The average direct medical cost of outpatient cares of diabetics per year was 155.8 US $. CONCLUSIONS The direct medical cost of diabetes management is progressed sharply in past years in Iran. Pharmaceutical expenditures was the main cost component of outpatient cares for diabetes. It is estimated that the Iranians directly spend approximately $4.05 milliard annually to manage 5.2 million diabetics in the country.

Abstract
OBJECTIVES We evaluated the ability of the visceral adiposity index (VAI) compared to hypertriglyceridemic-waist (HTGW) phenotype, body mass index (BMI), waist circumference (WC), waist-to-height ratio (WHtR) and waist-to-hip ratio (WHR) as a possible predictor of diabetes in a nondiabetic high-risk population. METHODS We analyzed 7-year follow-up data in nondiabetic first-degree relatives of consecutive patients 30 to 70 years of age with type 2 diabetes and with at least 1 follow-up examination (N=1720). The primary outcome was the diagnosis of type 2 diabetes based on repeated oral glucose tolerance tests. We examined the incidence of type 2 diabetes across quintiles of the VAI and plotted a receiver operating characteristic (ROC) curve to compare the abilities of predicting type 2 diabetes of the VAI, BMI, WC, WHR and WHtR. RESULTS The highest quintile of VAI compared with the lowest quintile was associated with type 2 diabetes in age- and gender-adjusted models (OR 2.45; 95% CI 1.56, 3.86). Those with the HTGW phenotype were 2.36 times (OR 2.36; 95% CI: 161, 3.44) more likely to develop type 2 diabetes than those with normal WCs and normal triglyceride levels. On ROC curve analysis, almost similar areas under the ROC were found for BMIs (60.9%; 95% CI: 57.1, 64.6); WC (61.0%, 95% CI 57.4, 64.5); WHtR (62.6%; 95% CI: 59.1, 66.2); WHR (55.7%; 95% CI 52.2, 59.3) and VAI (58.3%; 95% CI: 54.5, 62.1). CONCLUSIONS These data provide further evidence that VAI and HTGW are robust predictors of type 2 diabetes, but the predictive power was similar to that of BMI, WC, WHtR and WHR in our study population.

Abstract
Aim/Introduction We evaluated the association between hypertriglyceridemic waist (HTW) phenotype and the risks of type 2 diabetes in an Iranian high‐risk population. Materials and Methods We analyzed 7‐year follow‐up data (n = 1,865) in non‐diabetic first‐degree relatives of consecutive patients with type 2 diabetes aged 30–70 years. The primary outcome was the diagnosis of type 2 diabetes based on repeated oral glucose tolerance tests. We used multiple logistic regressions to estimate the odds ratio (OR) for incident type 2 diabetes across four groups according to baseline fasting serum triglycerides (TG) level and waist circumference (WC): normal WC and normal TG, normal WC and high TG, enlarged WC and normal TG, and HTW (enlarged WC high TG). Results The HTW phenotype at baseline was associated with the incidence of type 2 diabetes. Those with HTW were 2.4‐fold (OR 2.36, 95% confidence interval 1.61–3.44), those with normal WC high TG were 1.9‐fold (OR 1.87, 95% confidence interval 1.29–2.70) and those with enlarged WC but normal TG were 2.8‐fold (OR 2.84, 95% confidence interval 1.96–4.13) more likely to develop type 2 diabetes than those with normal WC and normal TG. Conclusions These data provide further evidence that the HTW phenotype is a robust predictor of type 2 diabetes in high‐risk individuals in Iran, and the predictive power is not higher than that of simple enlarged WC and normal TG, emphasizing the importance of enlarged WC to the development of type 2 diabetes.

Abstract
BACKGROUND Diabetes mellitus is a metabolic disorder and its subsequent complications such as retinopathy, nephropathy, ulcers, disability, and amputation increase the burden of the disease. Patient knowledge-improving programs are employed to prevent disease progression and to improve the quality of life of the patients. In this way, we need to characterize the groups of patients in urgent need for more and rich-in-content programs. In the present study, we used piecewise regression to evaluate the trends of diabetic nephropathy prevalence in patients registered in the Sedigheh-Tahereh Research Center and to identify patients who were in need of more attention. MATERIALS AND METHODS Piecewise regression, used in this study, is a statistical method to identify change points, if any, in the trends of mortality rates, prevalence of a disease, or any other trends. Available information for 1,935 patients were retrieved from the database. Joinpoint program 3.5.3 and Statistical Package for the Social Sciences (SPSS) 20 was used to fit piecewise regression and obtain descriptive statistics, respectively. RESULTS We assessed the trend of diabetic nephropathy in different groups of diabetic patients with respect to sex, blood pressure status, education, family history of diabetes, and age. The results showed an increasing trend in females, patients without family history of diabetes, and eover th recent years. The prevalence of diabetic nephropathy in patients with academic education was high. CONCLUSION The groups with high prevalence or increasing trends need more preventive intervention and detailed assessment of the present trends. Exploring high-risk groups is beneficial for better policy-making in the future. However, discovering the reasons for the increased trend of the disease is really helpful in controlling diabetes complications.

Abstract
Background: It is suggested that bromocriptine could be effective in treatment of prediabetic patients and, consequently, in preventing type 2 diabetes (T2DM). In this study, we investigated the effectiveness of bromocriptine on glycemic and metabolic control of prediabetic patients. Materials and Methods: In this double-blind, placebo controlled trial study, prediabetic patients diagnosed during Isfahan Diabetes Prevention Project (IDPP) were enrolled. They randomized in two bromocriptine (2.5 mg) and placebo-treated groups, for 12 weeks. After physical examination, fasting plasma glucose (FPG), HbA1c, Insulin, cholesterol, HDL-c, and triglyceride were measured and glucose tolerance test (OGTT) was performed. HOMA-IR and LDL-c were calculated. The mean of the data were compared in the bromocriptine and placebo treated groups, before and after intervention by intention to treat analysis using mixed effect model. P values < 0.05 were considered, statistically, significant. Results: In this study, 53 prediabetic patients (27 in the bromocriptine group and 26 in the placebo group) were treated. There were no differences between data of two groups at baseline (P > 0.05). The mean body mass index, systolic blood pressure, fasting plasma glucose and glucose of 30 min, 60 min, 120 min of post OGTT, HbA1c, insulin, HOMA-IR, lipid profile did not change, significantly, in both bromocriptine and placebo-treated groups after 12 weeks (P > 0.05). However, diastolic blood pressure (P = 0.02) and the area under the curve of glucose (P = 0.045) were decreased in the bromocriptine-treated group. Conclusion: Bromocriptine did not have significant effect on glycemic control of prediabetic patients. Further studies, with bigger sample size are recommended.

Abstract
BACKGROUND Type II diabetes mellitus (T2DM) is the prevalent type of diabetes in the world. Prediabetic patients are the most probable group to get diabetes. Several studies have mentioned the role of inflammation in the incidence of diabetes. The origin of inflammation can be infection such as Helicobacter pylori (HP) infection. This study was designed to explore the effect of HP eradication on insulin resistance. MATERIALS AND METHODS This single-blind randomized controlled clinical trial was conducted in 2014-2015. The sample size consisted of 49 individuals who were in prediabetes stage with HP infection. Patients with positive stool antigen were allocated randomly into two groups. The treatment group took medication to eradicate HP infection by the routine method of four-drug eradication. However, placebo capsules and tablets were given to the patients in the placebo group. Then fasting plasma glucose (FPG), fasting plasma insulin (FPI), and quantitative C-reactive protein (CRP) levels were measured and homeostatic model assessment of insulin resistance (HOMA-IR), homeostatic model assessment of beta-cell function (HOMA-B), Matsuda index, insulinogenic index, and disposition index were calculated. RESULTS Results of this study showed that FPI and HOMA-IR increased significantly (P value of FPI = 0.023 and P value of HOMA-IR = 0.019) after HP eradication in the treatment group. On the other hand, comparison of differences at the baseline and after 6 weeks in FPG (P value = 0.045), FPI (P value = 0.013), and HOMA-B (P value = 0.038) revealed significant differences between the placebo group and treatment group. CONCLUSION Results showed that HP eradication by a 2-week antibiotic medication did not decrease insulin resistance and even increased FPI and insulin resistance indices. So HP eradication among prediabetic patients is not recommended for the decrease of insulin resistance and postponement of the development of diabetes mellitus.

Abstract
BACKGROUND Morphine is related to dysregulation of serum hormone levels. In addition, addict subjects interest to sugar intake. Therefore, this study investigated the effect of co-administration of glucose with Mo on the glucoregulatory hormones and causing of diabetes mellitus in rats. MATERIALS AND METHODS Male rats were randomly divided into four groups including, control, morphine, Morphine-Glucose and diabetes groups. Morphine was undergone through doses of 10, 20, 30, 40, 50, and 60 mg/kg, respectively on days 1, 2, 3, 4, 5, and 6. Then, dose of 60 mg/kg was used repeated for 20 extra days. The Morphine-Glucose group received the same doses of morphine plus 1 g/kg glucose per day. Diabetes was induced by intraperitoneal injection of 65 mg/kg streptozotocin. At the end of experiment, the serum insulin, glucagon, growth hormone (GH), cortisol, and glucose levels were measured. The homeostasis model assessment (HOMA) indexes concluding the HOMA-insulin resistance (HOMA-IR) and HOMA-β were evaluated. RESULTS Morphine insignificantly induced a hyperglycemia condition and insulin resistance. Whereas, the beta-cell functions significantly (P < 0.05) decreased only in morphine group. The co-administration of glucose slightly increased the GH, and increased insulin and cortisol levels significantly (P < 0.05 and P < 0.01; respectively) in the Morphine-Glucose group. Furthermore, the co-administration of glucose with morphine could nearly modulate the morphine effects on body weight, glucose, and glucagon levels. CONCLUSION It is probable that the co-administration of glucose with morphine modulate the serum glucose levels by stimulating the beta-cell functions and to increase insulin secretion.

Abstract
AIM The present study was designed to estimate the progression rates from combination of normal weight, overweight, obesity, and number of metabolic abnormalities (MA) to type 2 diabetes (T2D) in a non-diabetic high risk population in Isfahan, Iran. METHODS A total of 1869 non-diabetic first-degree relatives (FDR) of patients with T2D 30-70 years old were examined and followed for a mean (SD) of 7.3 (2.2) years for T2D incidence. At baseline and through follow-up, participants underwent a standard 75-g 2-h oral glucose tolerance test. RESULTS The metabolically healthy overweight and obese at baseline were associated with incidence of T2D, independently of age and gender. Any one MA increased the risk of developing T2D among normal weight, overweight and obese individuals. Those with normal weight and ≥3 MA were over 20 times (odds ratios (OR) 20.21; 95% confidence intervals (CI) 2.4, 170.4) and those with overweight and ≥3 MA 22.5 times (OR 22.5; 95% CI 3.0, 167.0) and obese with ≥3 MA were 25.4 times (OR 25.4; 95% CI 3.4, 187) more likely to develop T2D than those with normal weight and without MA. Compared with participants without MA, obese individuals with concomitant MA were not significantly more likely to progress to T2D. CONCLUSION Our data provide further evidence that normal weight, overweight and obese individuals with MA had a higher risk of incident T2D than normal weight individuals without MA.

Abstract
BACKGROUND/AIM It is not clear whether levels of continuous metabolic syndrome (cMetS) are associated with type 2 diabetes (T2D). The aim of this study was to determine the ability of the cMetS score to predict progression to T2D in non-diabetic first-degree relatives (FDRs) of patients with T2D in Isfahan, Iran. METHODS A total of 1,869 non-diabetic FDRs 30-70 years old in 2003-2005 were followed through 2014 for the occurrence of T2D. At baseline and through follow-ups, participants underwent a standard 75 g 2-h oral glucose tolerance test. MetS was defined by the National Cholesterol Education Program-Adult Treatment Panel III. The cMetS score was calculated using age- and gender-standardized Z-score for MetS components. Receiver operating characteristic (ROC) curve was used to assess the association between cMetS and components of MetS with T2D. RESULTS During 13,571 person-years of follow-up, 72 men and 210 women developed diabetes. Those in the top quartile of cMetS were 8.0 times more likely to develop diabetes than those in the bottom quartile (OR 7.96; 95% CI 4.88-12.99). On ROC curve analysis, a higher area under the ROC were found for FPG (74.3%; 95% CI 70.8-77.8), than for cMetS (69.4%; 95% CI 66.0-72.8). CONCLUSIONS The cMetS score is a robust predictor of T2D and may be more effective and efficient than the current binary definition of MetS in predicting progression to T2D in our study population.

Abstract
AIMS/INTRODUCTION To estimate the prevalence of meeting American Diabetes Association clinical practice recommendations for hemoglobin A1c (HbA1c), blood pressure (BP) and low-density lipoprotein cholesterol (LDLC) among Iranian type 2 diabetes clinic attendees, and to identify the factors associated with therapeutic target achievement. MATERIALS AND METHODS A total of 2,640 patients with type 2 diabetes (944 men and 1,696 women) from Isfahan Endocrine and Metabolism Research Center outpatient clinics, Iran, were examined. The main outcome measures were HbA1c, BP and LDLC, in accordance with the American Diabetes Association recommendations. The mean (standard deviation) age of participants was 49.6 years (9.3 years) with a mean (standard deviation) duration of diabetes of 5.0 years (4.9 years) at initial registration. RESULTS The percentages of patients who had HbA1c <7%, BP <140/90 mmHg and LDLC <100 mg/dL was 37.4% (95% confidence interval [CI] 35.6-39.3), 35.3% (95% CI 33.5-37.3) and 48.9% (95% CI 47.0-50.8), respectively. The proportion of patients meeting all three goals was 7.7% (95% CI 6.7-8.8). Lower BP, cholesterol level and higher education at registration, and higher follow up but lower number of follow-up visits affected achievement of all three goals. CONCLUSIONS The present study highlights that a substantial proportion of Iranian type 2 diabetes clinic attendees did not meet the American Diabetes Association clinical practice recommendations, and shows the difficult challenges physicians face when treating patients with type 2 diabetes.
