Abstract
Heart failure (HF) is increasing at an alarming rate, primary due to the rising in aging, obesity and diabetes. Notably, individuals with type 1 diabetes (T1D) face a significantly elevated risk of HF, leading to more hospitalizations and increased case fatality rates. Several risk factors contribute to HF in T1D, including poor glycemic control, female gender, smoking, hypertension, elevated BMI, and albuminuria. However, early and intensive glycemic control can mitigate the long-term risk of HF in individuals with T1D. The pathophysiology of diabetes-associated HF is complex and multifactorial, and the underlying mechanisms in T1D remain incompletely elucidated. In terms of treatment, much of the evidence comes from type 2 diabetes (T2D) populations, so applying it to T1D requires caution. Sodium-glucose cotransporter 2 inhibitors have shown benefits in HF outcomes, even in non-diabetic populations. However, most of the information about HF and the evidence from cardiovascular safety trials related to glucose lowering medications refer to T2D. Glycemic control is key, but the link between hypoglycemia and HF hospitalization risk requires further study. Glycemic variability, common in T1D, is an independent HF risk factor. Technological advances offer the potential to improve glycemic control, including glycemic variability, and may play a role in preventing HF. In summary, HF in T1D is a complex challenge with unique dimensions. This review focuses on HF in individuals with T1D, exploring its epidemiology, risk factors, pathophysiology, diagnosis and treatment, which is crucial for developing tailored prevention and management strategies for this population.

Abstract
PURPOSE Hyperglycemia is associated with abnormalities of lipoproteins. The aim of this study was to analyze, in patients with Type 1 Diabetes (T1D), the association of glycemic control with lipid profile, focusing on glycemic variability and time in range obtained from Continuous Glucose Monitoring (CGM). METHODS We performed a retrospective cohort in patients with T1D. We analyzed clinical parameters, HbA1c, CGM and lipid profile in two moments 6 to 18 months apart. We evaluated the association of HbA1c and CGM metrics with lipid profile in cross-sectional (n = 242) and longitudinal (n = 90) analyses. RESULTS The mean age of the study population was 36.6 ± 12.6 years, 51.7% were male, and the mean diabetes duration was 16.8 ± 10.3 years. In the cross-sectional analysis, higher HbA1c, higher glucose management indicator (GMI), higher time above range and lower time in range were associated with higher triglyceride levels. In the longitudinal analysis, an increase in time below range was associated with a decrease of HDL cholesterol. In both analyses, an increase in the coefficient of variability (CV) was associated with a significant decrease of HDL cholesterol. HbA1c and CGM were not associated with total cholesterol or LDL cholesterol. CONCLUSIONS We observed a negative association between CV and HDL cholesterol levels and a positive association between hyperglycemia metrics and triglyceride levels. These findings suggest that CGM parameters may be a helpful tool to guide the improvement of both glycemic control and lipid profile in T1D.

Abstract
BACKGROUND Dyslipidemia and type 2 diabetes mellitus (T2DM) are growing health problems, particularly in developing countries. This study aimed to determine the prevalence and pattern of dyslipidemia and its associated factors among patients with T2DM. METHODS A cross-sectional study was conducted among patients with T2DM attending Family Medicine Clinics in Jordan between August 2017 and March 2019. The socio-demographics, clinical features, medications, and laboratory findings were collected. These laboratory findings included high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC), and triglycerides (TGs). RESULTS A total of 870 patients with T2DM were included. The prevalence of dyslipidemia among patients with T2DM was 91.4%. The most common patterns of dyslipidemia were low HDL-C (66.2%), high LDL-C (62.1%), and hypertriglyceridemia (58.2%). Female gender, obesity, and hypertension were associated with diabetic dyslipidemia patterns. T2DM duration and poor glycemic control were associated with high LDL-C and hypercholesterolemia. Hypertriglyceridemia was associated with poor glycemic control and smoking. CONCLUSION Dyslipidemia is highly prevalent among patients with T2DM. Evidence -based interventions are needed to prevent and control dyslipidemia among patients with T2DM in Jordan.

Abstract
Objective: Dyslipidemia is prevalent in adults living with type 1 diabetes, and it can worsen the presentation of microvascular complications such as retinopathy. This study aims to identify the pattern coupled with the frequency of dyslipidemia in diabetic adults who followed up at different clinics in King Abdulaziz Medical City, Riyadh, and evaluate the associations with demographic and clinical characteristics. Methods: A cross-sectional, retrospective chart review study of 514 adults with type 1 diabetes was conducted in a tertiary health care facility in the central region of Saudi Arabia. Demographics were retrieved by using the implemented electronic medical records. Fasting lipid profile, glycated hemoglobin (HbA1c), and thyroid-stimulating hormone (TSH) levels were checked for all subjects. Results: Five hundred and fourteen (514) subjects aged 18-65 years were studied (mean age: 26.1 ± 7.1 years). There were 318 (62%) females in the sample, and their mean age was significantly different from the mean age of males (p = 0.01). The mean duration of having diabetes was 12.8 ± 6.9 years. The prevalence of lipid abnormalities included abnormal low-density lipoprotein (LDL) (70%), hypercholesterolemia (23%), abnormal high-density lipoprotein (HDL) (8%), and hypertriglyceridemia (5%). Abnormal HDL was significantly higher in males than in females (p=<0.001). There were no statistically significant differences in the prevalence of other lipid abnormalities between the two genders and the age group < or ≥ 25 years. There was no statistically significant difference in the mean of the tested lipids levels between the two genders. One hundred and forty-three (143) (27.8%) patients had more than one abnormal lipid condition. A statistically significant difference was observed in the mean HbA1c between males and females (p=0.001). Otherwise, there was no significant association of lipid abnormalities with gender, age, diabetes duration, and weight. Conclusion: The most prevalent lipid abnormality was high LDL cholesterol. Nearly a third of the tested individuals had more than one lipid abnormality. Furthermore, poor glycemic control was linked to abnormal lipid profiles. Consequently, local programs must aim to screen and intervene early to delay and prevent future severe vascular complications related to non-treated dyslipidemia.

Abstract
BACKGROUND Microvascular complications are common in people with diabetes, where poor glycaemic control is the major contributor. The aim of this study was to explore the association between elevated LDL cholesterol levels and the risk of retinopathy or nephropathy in young individuals with type 1 diabetes. METHODS This was a nationwide observational population-based cohort study, including all children and adults with a duration of type 1 diabetes of ≤ 10 years, identified in the Swedish National Diabetes Register between 1998 and 2017. We calculated the crude incidence rates with 95% confidence intervals (CIs) and used multivariable Cox regression to estimate crude and adjusted hazard ratios (HRs) of retinopathy or nephropathy in four LDL cholesterol categories: <2.6 (Reference), 2.6-3.4, 3.4-4.1 and > 4.1 mmol L-1 . RESULTS In total, 11 024/12 350 (retinopathy/nephropathy, both cohorts, respectively) children and adults (median age 21 years, female 42%) were followed up to 28 years from diagnosis until end of study. Median duration of diabetes when entering the study was 6 and 7 years in the retinopathy and nephropathy cohort, respectively. Median LDL cholesterol was 2.4 mmol L-1 , and median HbA1c level was 61 mmol mol-1 (7.7 %). After multivariable adjustment, the HRs (95% CI) for retinopathy in individuals with LDL cholesterol levels of 2.6-3.4, 3.4-4.1 or > 4.1 mmol L-1 were as follows: 1.13 (1.03-1.23), 1.16 (1.02-1.32) and 1.18 (0.99-1.41), compared with the reference. The corresponding numbers for nephropathy were as follows: 1.15 (0.96-1.32), 1.30 (1.03-1.65) and 1.41 (1.06-1.89). CONCLUSIONS Young individuals with type 1 diabetes exposed to high LDL cholesterol levels have an increased risk of retinopathy and nephropathy independent of glycaemia and other identified risk factors for vascular complications.

Abstract
Overweight and obesity are an increasingly common problem, not only among the healthy population, but also in adolescents with type 1 diabetes (T1DM). Excess body weight is related to many cardiometabolic complications as well as a high risk of metabolic syndrome (MetS). The purpose of this systematic review is to provide a concise and critical overview of the prevalence of MetS in children and adolescents with T1DM and, ultimately, to discuss prevention and treatment options. The study was conducted in accordance with PRISMA guidelines. This review shows that, apart from the growing percentage of overweight and obese children and adolescents with T1DM (on average 20.1% and 9.5%, respectively), the problem of the increasing incidence of MetS (range from 3.2 to 29.9%, depending on the criteria used) is one of the most important phenomena of our time. One of the methods of prevention and treatment is a combined approach: changing eating habits and lifestyle, but there are also reports about the beneficial effects of the gut microflora.

Abstract
Cardiovascular disease (CVD) is a major cause of mortality in type 1 diabetes mellitus (T1DM) patients, and cardiovascular risk (CVR) remains high even in T1DM patients with good metabolic control. The underlying mechanisms remain poorly understood and known risk factors seem to operate differently in T1DM and type 2 diabetes mellitus (T2DM) patients. However, evidence of cardiovascular risk assessment and management in T1DM patients often is extrapolated from studies on T2DM patients or the general population. In this review, we examine the existing literature about the prevalence of clinical and subclinical CVD, as well as current knowledge about potential risk factors involved in the development and progression of atherosclerosis in T1DM patients. We also discuss current approaches to the stratification and therapeutic management of CVR in T1DM patients. Chronic hyperglycemia plays an important role, but it is likely that other potential factors are involved in increased atherosclerosis and CVD in T1DM patients. Evidence on the estimation of 10-year and lifetime risk of CVD, as well as the efficiency and age at which current cardiovascular medications should be initiated in young T1DM patients, is very limited and clearly insufficient to establish evidence-based therapeutic approaches to CVD management.

Abstract
Uncontrolled type-1 diabetes (T1DM) can lead to dyslipidaemia and albuminuria, which may promote cardiovascular injuries. However, some lipidemic factors could be useful in predicting cardiac dysfunction. Seventy-eight adolescents under insulin treatment due to a 6-year history of T1DM and were retrospectively examined. Glycemia, lipidemia, and albuminuria were measured in addition to development of cardiovascular abnormalities Both girls and boys showed higher HbA1c and fasting blood glucose and 27.1% females and 33.3% males exhibited microalbuminuria though their plasma levels of total cholesterol (TC), triglycerides (TG), and low-density lipoproteins (LDL) and high-density lipoproteins (HDL lipoproteins were in the normal range. They exhibited a preserved systolic function, but 50% of females and 66.6% of males had developed diastolic failures. Interestingly, girls with diastolic dysfunction showed significantly lower concentrations of HDL and higher TC/HDL and TG/HDL ratios. In fact, low HDL levels (OR 0.93; 95% CI 0.88-0.99; p = 0.029) and high TC/HDL (OR 2.55; 95% CI 1.9-5.45; p = 0.016) and TG/HDL (OR 2.74; 95% CI 1.12-6.71; p = 0.028) ratios associated with the development of diastolic complications. The cut-off values for HDL, TC/HDL, and TG/HDL were 49 mg/dL, 3.0 and 1.85, respectively. HDL and TC/HDL and TG/HDL ratios may be useful for predicting diastolic dysfunction in girls with uncontrolled T1DM.

Abstract
BACKGROUND Insulin resistance (IR) plays a great role in type 1 diabetes (T1DM) disease process than is commonly recognized. Dipeptidyl peptidase-4 (DPP-4) is an enzyme that deactivates many bioactive peptides involved in glucose regulation. AIMS This study evaluates DPP-4 level in adolescent patients with T1DM compared to controls and investigates the relationship between DPP-4 level and IR in these patients. MATERIALS AND METHODS We measured serum DPP-4 level in 50 patients with T1DM recruited from the Diabetes Endocrine Metabolism Pediatric Unit, and in 80 healthy controls. IR was assessed by the equation for estimated glucose disposal rate (eGDR). Biochemical evaluation including glycated haemoglobin (HbA1C) and lipid profile were included. RESULTS IR was found in 80% of patients with T1DM. DPP-4 was significantly higher in control group than patients with T1DM. Patients with T1DM were classified into 3 groups according to DPP-4 tertiles showing significant increase in BMI SDS and total cholesterol across the 3 groups. Significant correlation was found between DPP-4 levels and insulin dose. DPP-4 was significantly higher in patients with T1DM with good glycemic control. CONCLUSION In sample of individuals researched by us, serum DPP-4 was related to adiposity and not to the hyperglycemia in patients with T1DM. Larger sample should be researched to make firm conclusions.

Abstract
Objective: To assess the frequency of the hypertriglyceridemic waist phenotype and its
associated factors in children and adolescents with type 1 diabetes
mellitus. Methods: This is an observational analytical study with individuals with type 1
diabetes mellitus, aged 5 to 18 years, of both genders, followed in a
university hospital in the Brazilian Northeast. Weight, height, and waist
circumference were measured, and the lipid profile and glycated hemoglobin
were analyzed. The hypertriglyceridemic waist phenotype was defined by the
simultaneous presence of increased waist circumference (≥90th
percentile for age and gender) and elevated serum triglyceride levels (≥75
mg/dL for children and ≥90 mg/dL for adolescents). We also investigated the
family history of cardiovascular diseases and diabetes, as well as
sociodemographic and behavioral variables. In the statistical inference
tests, the proportions were compared by Pearson’s chi-square test and/or
Fisher’s exact test, being significant p<0.05. Results: A total of 102 patients were evaluated, most of them females (54.9%) and
adolescents (66.7%). The frequency of hypertriglyceridemic waist was 23.5%,
which was associated with females (p=0.043), overweight (p=0.023),
hypercholesterolemia (p=0.002), high LDL (p=0.001), and borderline VLDL
(<0.001). Conclusions: The frequency of the hypertriglyceridemic waist phenotype was associated
with females, atherogenic lipid profile, and overweight, indicating the
importance of the nutritional monitoring of this population, aiming at
reducing future cardiovascular diseases.

Metabolic aberrations in pediatric type 1 diabetes (T1DM) are of high clinical importance and could be addressed via breathomics. Real-time breath analysis was combined with continuous glucose monitoring (CGM) and blood tests in children suffering from T1DM and age-matched healthy controls in a highly standardized setting. CGM and breath-resolved VOC analysis were performed every 5 minutes for 9 hours and blood was sampled at pre-defined time points. Per participant (n = 44) food intake and physical activity were identical and a total of 22 blood samples and 93 minutes of breath samples were investigated. The inter-individual variability of glucose, insulin, glucagon, leptin, and soluble leptin receptor relative to food intake differed distinctly between patients and controls. In T1DM patients, the exhaled amounts of acetone, 2-propanol, and pentanal correlated to glucose concentrations. Of note, the strength of these correlations strongly depended on the interval between food intake and breath sampling. Our data suggests that metabolic adaptation through postprandial hyperglycemia and related oxidative stress is immediately reflected in exhaled breath VOC concentrations. Clinical translations of our findings may enable point-of-care applicability of online breath analysis towards personalized medicine.

The renal resistive index as a new complementary tool to predict microvascular diabetic complications in children and adolescents: a groundbreaking finding. ANNALS OF TRANSLATIONAL MEDICINE 2019; 7:422.

Abstract
The increasing prevalence of type 1 diabetes mellitus (DM) has made it necessary to have new markers for early detection of diabetic nephropathy. Renal resistive index (RI) by using renal Doppler can be a helpful tool in detecting functional alterations in renal hemodynamics. This study was conducted on 100 children and adolescents with type 1 DM. They were further subdivided into two equal subgroups: group 1 with type 1 DM and normo-albuminuria [urinary albumin excretion (UAE) <30 mg/24 hours], and group 2 with type 1 DM and hyper-albuminuria (increased UAE >30 mg/24 hours). There were 37 males (37%) and 63 females (63%); their mean ages were 13.6±2.53 (range, 10-19) years and mean disease duration was 8.867±2.260 (range, 5-13) years. Progressive increase in RI was significantly associated with increased disease duration more than 10 years, elevated serum HbA1c more than 7.5% and early pubertal stages. While not significantly related to sex, weight, height, blood pressure or serum lipid profile, diabetic micro-vascular complications (nephropathy and sensory neuropathy) were more prevalent among patients with RI more than 0.58. Renal RI could be a useful complementary test for the evaluation of functional alterations in renal hemodynamics in the early stages of diabetic nephropathy.

Abstract
AIM Dyslipidemia is an established marker for endothelial dysfunction and cardiovascular risk in diabetes. So we aimed to explore the prevalence of dyslipidemia in patients with type2 diabetes mellitus (DM) and to determine the association between dyslipidemia and other health care and biochemical indicators. MATERIALS AND METHODS A cross-sectional study was carried out at private health care center. A total of 291 diabetic patients aged 18 years and above attended the clinic from August 2017 through April 2018 were included. Socio-demographic, clinical, and laboratory data were obtained from the medical records of patients. Statistical analysis was carried out using (SPSS, version 23). RESULTS out of the 291 diabetes patients recruited 22.3% had hypercholesterolemia (TC ≥ 200) and 61.9% had hypertriglyceridemia. Abnormal LDL-C levels (≥130) were found in 8.9% of patients and HDL-C was less than 40 mg/dl in 54.3%. There was a statistically significant difference (P = 0.048) in abnormal HDL levels (˂ 40 mg/dl) among females (59.3%) and males (47.6). Patients with HbA1c values ≥ 7.0%had significantly higher values of total cholesterol (TC) and abnormal LDL-C compared with the patients who had HbA1c ˂ 7.0%. CONCLUSION dyslipidemia is highly prevalent among diabetic population particularly in those with poorly controlled diabetes. This calls for early and universal screening of lipid profile. There is also an urgent demand for measures that target tight glycemic, optimal lipid profile control and life style modifications is also required to all diabetic patients to achieve target value of HbA1C ≤ 7.

Abstract
Background There is limited information about cardiovascular complications among young adults (YA) with type 1 diabetes mellitus (T1DM) who are transitioning from pediatric to adult care. We aimed to study the prevalence and associated factors of dyslipidemia (DLD) and statin treatment in these patients. Methods We recruited 129 YA with T1DM aged 15-25 years. In a cross-sectional analysis, the prevalence of DLD (low-density lipoprotein cholesterol [LDL-C] ≥ 100 mg/dL, high-density lipoprotein cholesterol [HDL-C] <40 mg/dL [males] or <50 mg/dL [females], total cholesterol [TC] ≥200 mg/dL or triglycerides [TG] ≥150 mg/dL) was reported. Socioeconomic and clinical characteristics were compared between YA with and without DLD. We also assessed statin use among YA with DLD. Results DLD was found in 64% of YA, predominantly increased LDL-C (34.9%). Higher mean glycated hemoglobin (HbA1c) was associated with DLD (p < 0.043). Of all YA who met the criteria for statin therapy, only 42% had one prescribed. Conclusions The prevalence of DLD is high in YA with T1DM and is associated with poor glycemic control, and use of statin therapy in this high-risk population is low.

Abstract
<b><i>Background:</i></b> Dyslipidaemia is prevalent in children and adolescents with type 1 diabetes and can worsen the presentation of chronic complications such as nephropathy, retinopathy, and neuropathy. The aim of this study is to determine the frequency of dyslipidaemia in children living with diabetes followed up at a paediatric endocrine clinic in southern Nigeria and to identify associations with demographic and clinical characteristics. <b><i>Methods:</i></b> The study is a cross-sectional, descriptive study of 22 children with diabetes followed up in a tertiary health care facility in southern Nigeria. Demographic data were retrieved from case files, and fasting lipid profile and HbA<sub>1c</sub> levels were determined for all subjects. Lipid abnormalities were defined based on the Expert Panel on Integrated Guidelines for Cardiovascular Health Risk Reduction in Children and Adolescents. <b><i>Results:</i></b> Twenty-two subjects aged 7–18 years were studied (mean age: 14.94 ± 3.59 years). There were 12 (54.5%) females. Both genders were comparable regarding age (<i>p</i> = 0.95). Mean duration of diabetes was 3.37 ± 2.38 years. Prevalence of lipid abnormalities include: hypertriglyceridaemia (86.4%), hypercholesterolemia (22.7%), abnormal HDL-C (36.4%), high LDL-C (13.6%), and non-HDL-C (22.7%). Hypercholesterolaemia was significantly higher in females (<i>p</i> = 0.02), and prevalence of hypertriglyceridaemia was higher in subjects ≥12 years (<i>p</i> = 0.019). There was no statistically significant difference in mean levels of various lipids between males and females. Six (27.3%) subjects had more than one lipid abnormality. There was no statistically significant association of lipid abnormalities with age, sex, weight category, and HbA<sub>1c</sub> level. <b><i>Conclusion:</i></b> The commonest lipid abnormality was hypertriglyceridaemia. About a quarter of the subjects had more than 1 lipid abnormality. Programs should therefore be targeted at improved control of glycemia and lipid levels to delay and prevent chronic complications.

Abstract
Background The pathophysiology of cardiovascular complications in people with type 1 diabetes (T1DM) remains unclear. An increase in epicardial adipose tissue (EAT) and alterations in the composition of high-density lipoprotein (HDL) are associated with coronary artery disease, but information on its relationship in T1DM is very limited. Our aim was to determine the association between EAT volume, subclinical atherosclerosis, and HDL composition in type 1 diabetes. Methods Seventy-two long-term patients with T1DM without clinical atherosclerosis were analyzed. EAT volume and subclinical atherosclerosis were measured using cardiac computed tomography angiography. EAT was adjusted according to body surface to obtain an EAT index (iEAT). HDL composition was determined. Results The mean iEAT was 40.47 ± 22.18 cc/m2. The bivariate analysis showed positive associations of the iEAT with gender, age, hypertension, dyslipidemia, smoking, body mass index, waist circumference, insulin dose, and triglyceride (P < 0.05). The iEAT correlated positively with small HDL, increased content of apolipoprotein (apo)A-II and apoC-III, and decreased content of apoE and free cholesterol. Multiple linear regression showed that age, apoA-II content in HDL, and waist circumference were independently associated with the iEAT. Fifty percent of the patients presented subclinical atherosclerotic lesions. These patients had a higher iEAT, and their HDL contained less cholesterol and more apoA-II and lipoprotein-associated phospholipase A2 than patients without subclinical atherosclerosis. Conclusion Alterations in the composition of HDL in TIDM are associated with increased iEAT and the presence of subclinical atherosclerosis. We propose that these abnormalities of HDL composition could be useful to identify T1DM patients at highest cardiovascular risk.

High density lipoprotein modulates osteocalcin expression in circulating monocytes: a potential protective mechanism for cardiovascular disease in type 1 diabetes. Cardiovasc Diabetol 2017; 16:116. [PMID: 28915881 PMCID: PMC5602856 DOI: 10.1186/s12933-017-0599-2] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/21/2017] [Accepted: 09/07/2017] [Indexed: 12/12/2022] Open
Abstract
Background Cardiovascular disease (CVD) is a major cause of mortality in type 1 diabetes (T1D). A pro-calcific drift of circulating monocytes has been linked to vascular calcification and is marked by the surface expression of osteocalcin (OCN). We studied OCN+ monocytes in a unique population with ≥50 years of T1D, the 50-Year Joslin Medalists (J50M). Methods CD45 bright/CD14+/OCN+ cells in the circulating mononuclear blood cell fraction were quantified by flow cytometry and reported as percentage of CD45 bright cells. Mechanisms were studied by inducing OCN expression in human monocytes in vitro. Results Subjects without history of CVD (n = 16) showed lower levels of OCN+ monocytes than subjects with CVD (n = 14) (13.1 ± 8.4% vs 19.9 ± 6.4%, p = 0.02). OCN+ monocytes level was inversely related to total high density lipoprotein (HDL) cholesterol levels (r = −0.424, p = 0.02), large (r = −0.413, p = 0.02) and intermediate (r = −0.445, p = 0.01) HDL sub-fractions, but not to small HDL. In vitro, incubation with OxLDL significantly increased the number of OCN+ monocytes (p < 0.01). This action of OxLDL was significantly reduced by the addition of HDL in a concentration dependent manner (p < 0.001). Inhibition of the scavenger receptor B1 reduced the effects of both OxLDL and HDL (p < 0.05). Conclusions Low OCN+ monocytes levels are associated with lack of CVD in people with long duration T1D. A possible mechanism for the increased OCN+ monocytes could be the elevated levels of oxidized lipids due to diabetes which may be inhibited by HDL. These findings suggest that circulating OCN+ monocytes could be a marker for vascular disease in diabetic patients and possibly modified by HDL elevation.

Abstract
BACKGROUND Dyslipidemia increases the frequency and severity of micro and macrovascular complications of type 1 diabetes (T1D). The present study aims to determine the prevalence of dyslipidemia and its association with clinical and laboratory findings in diabetic children and adolescents. METHODS The study included 202 children and adolescents with T1D. Demographic data and laboratory findings were obtained from patients files. RESULTS Dyslipidemia prevalence was found to be 26.2%. Hypercholesterolemia (15.8%) and hyperglyceridemia (12.9%) were most common findings. Age, body mass index (BMI), hemoglobin A1c (A1C) and poor metabolic control were significantly higher in cases with dyslipidemia. Smoking rate was 14.1% in the pubertal group. Poor metabolic control and dyslipidemia was found higher among smokers (p<0.05). CONCLUSIONS Blood lipid levels should be monitored regularly and nutrition education should be repeated periodically to prevent and control dyslipidemia in patients with T1D. Smoking-related risks should be a part of patient education in the pubertal period.

Abstract
Women with type 1 diabetes (T1DM) have unique needs during the preconception, pregnancy, and postpartum periods. Preconception counseling is essential for women with T1DM to minimize pregnancy risks. The goals of preconception care should be tight glycemic control with a hemoglobin A1c (A1C) < 7 % and as close to 6 % as possible, without significant hypoglycemia. This will lower risks of congenital malformations, preeclampsia, and perinatal mortality. The safety of medications should be assessed prior to conception. Optimal control of retinopathy, hypertension, and nephropathy should be achieved. During pregnancy, the goal A1C is near-normal at <6 %, without excessive hypoglycemia. There is no clear evidence that continuous subcutaneous insulin infusion (CSII) versus multiple daily injections (MDI) is superior in achieving the desired tight glycemic control of T1DM during pregnancy. Data regarding continuous glucose monitoring (CGM) in pregnant women with T1DM is conflicting regarding improved glycemic control. However, a recent CGM study does provide some distinct patterns of glucose levels associated with large for gestational age infants. Frequent eye exams during pregnancy are essential due to risk of progression of retinopathy during pregnancy. Chronic hypertension treatment goals are systolic blood pressure 110-129 mmHg and diastolic blood pressure 65-79 mmHg. Labor and delivery target plasma glucose levels are 80-110 mg/dl, and an insulin drip is recommended to achieve these targets during active labor. Postpartum, insulin doses must be reduced and glucoses closely monitored in women with T1DM because of the enhanced insulin sensitivity after delivery. Breastfeeding is recommended and should be highly encouraged due to maternal benefits including increased insulin sensitivity and weight loss and infant and childhood benefits including reduced prevalence of overweight. In this article, we discuss the care of pregnant patients with T1DM.

Abstract
OBJECTIVE The association between type 1 diabetes mellitus (T1D) and dyslipidemia (DLP) increases the risk of cardiovascular disease (CVD). The aim of this study was to evaluate the presence of dyslipidemia in young T1D patients. MATERIALS AND METHODS The study design was cross-sectional and descriptive. We reviewed medical records of T1D patients followed at an endocrinology service, from 1998-2012. DATA COLLECTED gender, actual age and age at diagnosis, duration of T1D since diagnosis, body mass index (BMI), pubertal stage, glycemic control (GC) determined by glycated hemoglobin (HbA1c), total cholesterol (TC), HDL, LDL, triglycerides (TG). To analyze lipid profile and metabolic control, we used the Brazilian Society of Diabetes Guidelines. RESULTS Were included 239 T1D patients, 136 (56.9%) females; mean ± SD: actual age 15.7 ± 5.0 years and at T1D diagnosis 7.3 ± 3.9; T1D duration 10.6 ± 6.4 years, 86.6% puberty, 15.1% overweight. The prevalence of DLP was 72.5%, 63.3% females, 86.6% puberty, mean ± SD: actual age 15.4 ± 4.8 years and at T1D diagnosis 7.2 ± 4.1 years, duration of T1D 10.7 ± 6.1 years. We found high-CT in 56.7%, low-HDL = 21.7%, high LDL = 44.0%, high-TG = 11.8%. Between females with DLP, 83.5% was in puberty. We find correlation between the presence of DLP, a poor GC and BMC. CONCLUSION We found a high prevalence of DLP in young patients with T1D, particularly in puberty females. Programs targeting the prevention of dyslipidemia should be adopted, especially for this group, in order to prevent/delay chronic complications and cardiovascular disease.

Abstract
Patients with type 1 diabetes mellitus (T1DM) traditionally had a low body mass index and microangiopathic complications were common, while macroangiopathy and the metabolic syndrome were exceptional. The Diabetes Control and Complications Trial, published in 1993, demonstrated that therapy aimed at maintaining HbA1c levels as close to normal as feasible reduced the incidence of microangiopathy. Since then, the use of intensive insulin therapy to optimize metabolic control became generalized. Improved glycemic control resulted in a lower incidence of microangiopathy; however, its side effects included a higher rate of severe hypoglycemia and increased weight gain. Approximately 50% of patients with T1DM are currently obese or overweight, and between 8% and 40% meet the metabolic syndrome criteria. The components of the metabolic syndrome and insulin resistance have been linked to chronic T1DM complications, and cardiovascular disease is now the leading cause of death in these patients. Therefore, new therapeutic strategies are required in T1DM subjects, not only to intensively lower glycemia, but to control all associated metabolic syndrome traits.

Abstract
INTRODUCTION This study evaluated the effects of low-level laser therapy (LLLT) on human skin fibroblasts (HSFs) that have been cultured in high glucose concentration media. MATERIALS AND METHODS HSFs were cultured under physiological glucose condition medium, and then cultured in high glucose concentration medium (15 mM/L) for 1 or 2 weeks prior to LLLT. Experimental HSFs were irradiated with three energy densities (0.5, 1, and 2 J/cm(2)) once daily for three consecutive days. Release of interleukin-6 (IL-6) and basic fibroblast growth factor (bFGF) was evaluated using the enzyme-linked immunosorbent assay (ELISA) method. RESULTS Statistical analysis showed three doses of 0.5 (p = 0.049), 1 (p = 0.027), and 2 J/cm(2) (p = 0.004) stimulated the release of IL-6 in HSFs cultured in high glucose concentration medium compared with that of non-irradiated HSFs that were cultured in the same medium. LLLT with 2 J/cm(2) induced the release of bFGF from HSFs cultured in high glucose concentration medium for 1 or 2 weeks (both p = 0.04). CONCLUSION Our study showed that LLLT stimulated the release of IL-6 and bFGF from HSFs cultured in high glucose concentration medium. LLLT was more effective in releasing IL-6 and bFGF while HSFs which were cultured in physiologic glucose concentration medium during laser irradiation.

Abstract
BACKGROUND Cardiovascular disease is seen at a younger age and at a higher prevalence in patients with type 1 diabetes than in the general population. It is well described that women with type 1 diabetes have a higher relative risk of cardiovascular disease than men with type 1 diabetes, unlike that seen in the general population. The pathophysiology behind this is unknown. OBJECTIVE We performed a cross-sectional study to examine sex differences in cardiovascular disease risk factors in adolescents with type 1 diabetes between ages 13 and 20 years, compared with children of a similar age without type 1 diabetes. METHODS All patients underwent a dual energy x-ray absorptiometry scan to measure body composition and a pulse wave test measure of arterial elasticity. Fasting serum lipid levels, apolipoprotein B, and apolipoprotein C-III levels were measured in each patient. Twenty-nine children with type 1 diabetes (10 girls, 19 boys) and 37 healthy children (18 girls, 19 boys) participated. RESULTS Although no sex differences for body mass index (P = 0.91) and glycosylated hemoglobin (P = 0.69) were seen, girls with type 1 diabetes had a significantly higher percent trunk fat compared with boys (P = 0.004). No sex differences were found (P > 0.05) for percent trunk fat in adolescents without diabetes. There was no sex difference among any other cardiovascular risk factors in either children with or without diabetes. CONCLUSIONS Female adolescents with type 1 diabetes have more centrally distributed fat, which may contribute to their relatively higher cardiovascular disease risk. Attenuation of the central distribution of fat through exercise and dietary modifications may help ameliorate their subsequent cardiovascular disease burden.

Abstract
The objective of the study is to assess coronary artery calcification (CAC) among adolescents with type-1 diabetes and to determine its relation with high-sensitivity C-reactive protein (hs-CRP), dyslipidaemia, glycaemic control and microvascular complications. The study included sixty patients with type-1 diabetes. Their ages ranged from 12 to 18 years and their diabetes duration ranged between 10 and 15 years. Patients were compared with 60 healthy subjects who served as controls. Clinical examination and laboratory investigations were done for evaluation of glycaemic control and presence of microvascular complications. Lipid profile, hs-CRP and multislice spiral computed tomography were done. Hs-CRP, total cholesterol, triglycerides and low-density lipoproteins levels were significantly higher in patients with diabetes compared to controls (P < 0.001). Twelve patients with diabetes (20%) had positive CAC. The mean calcium score was significantly higher in patients with diabetes compared to controls (P < 0.05). Smoking significantly affects CAC as 50% of smokers with diabetes had evidence of CAC compared to 9.1% of non-smokers with diabetes (P < 0.001). Fifty percent of patients with diabetes on angiotensin-converting enzyme inhibitor (ACEI) had evidence of CAC compared to 0% of patients without history of ACEI therapy (P < 0.001). Diabetics with CAC had significantly elder age, longer disease duration and higher mean glycosylated hemoglobin compared to diabetics without CAC (P < 0.05). Blood pressure percentiles, albumin creatinine ratio and serum lipids were significantly higher in patients with CAC compared to those without CAC (P < 0.001). All diabetics with severe retinopathy had positive CAC compared to 0% with normal Fundus (P < 0.001). All diabetics with overt nephropathy had positive CAC compared to 13.3% and 0% in micro- and normo-albuminuric patients (P < 0.001). Young patients with diabetes have evidence of CAC. Smoking, microvascular complications and dyslipidaemia might contribute to this risk.

Abstract
INTRODUCTION AND OBJECTIVES Numerous clinical and epidemiological studies have highlighted the fact that metabolic syndrome is an important precursor of cardiovascular disease. Metabolic syndrome is generally associated with type-2 diabetes, and few data exist on its occurrence in type-1 diabetes. The aims of this study were to determine the prevalence of metabolic syndrome in patients with type-1 diabetes and to identify associated factors. METHODS This cross-sectional study included consecutive patients aged over 18 years with autoimmune type-1 diabetes of more than 6 months' duration who were treated during 2008 at the Outpatient Endocrinology Clinic of the Hospital del Mar, Barcelona, Spain. The presence of metabolic syndrome was determined using the modified criteria proposed by the National Cholesterol Education Program-Adult Treatment Panel III. RESULTS Overall, 31.9% (95% confidence interval [CI], 22.3%-41.5%) of patients with type-1 diabetes had metabolic syndrome. The following factors were significantly and independently associated with the presence of metabolic syndrome in patients with type-1 diabetes: age (odds ratio [OR]=1.09; 95% CI, 1.029-1.154), body mass index (OR=1.389; 95% CI, 1.134-1.702) and glycosylated hemoglobin level (OR=1.745; 95% CI, 1.081-2.815). In addition, there was a direct relationship between the number of components of metabolic syndrome present and prevalence of microangiopathy, which reached 100% in patients who satisfied all diagnostic criteria. CONCLUSIONS Metabolic syndrome was common in patients with type-1 diabetes and was associated with microvascular complications.

Abstract
BACKGROUND Studies on cardiovascular risk factors among diabetic persons in Ethiopia are lacking. The objective of this study was to determine the prevalence of the cardiovascular risk factors (hypertension, obesity, physical inactivity, dyslipidemia and smoking) among diabetic patients at the diabetic clinic of Jimma University Specialized Hospital. METHODS A cross-sectional study was conducted from October to December 2007. Three hundred one individuals were randomly selected from 950 patients on follow-up. Data were collected using a structured format and appropriate equipments and reagents. Laboratory data were recorded in a separate checklist. The data were entered into SPSS for Windows version 12. Multivariate regression analysis was carried out to identify predictors of hypertension, obesity and dyslipidemia. RESULTS Two hundred and fifty six (85.1%) of the sample participated in the study. The prevalence of hypertension, obesity, dyslipidemia, physical inactivity and current smoking was 46.5%, 23.4%, 63.5%, 55.1% and 5.5% respectively. Age ≥ 45 years, type 2 diabetes and obesity were predictors of hypertension. Females were less likely to be hypertensive (OR =2.26, 3.37, 3.79 and 0.48 respectively). Type 2 diabetics and females were more while rural diabetics were less likely to be obese. (OR =6.08, 4.17 and 0.37 respectively). Female gender, hypertension and fasting blood glucose ≥ 180mg/dl were predictors of dyslipidemia. Alcohol users were less likely to be dyslipidemic. (OR =4.25, 3.5, 3.56 and 0.39, respectively) CONCLUSION Hypertension, obesity, dyslipidemia and physical inactivity were common while smoking was uncommon among diabetic patients in Jimma University Specialized Hospital. Type 2 DM was a predictor of hypertension and obesity. Diabetic women were more likely to be obese and dyslipidemic. We recommend screening and management of these risk factors.

Abstract
BACKGROUND Diabetes mellitus (DM) is a disorder that is often associated with cardiovascular events and underlying lipid abnormalities. Cardiovascular complications are common causes of DM deaths in Nigeria yet dyslipidaemia is one aspect of DM that is underdiagnosed and undertreated in our patients. This report seeks to determine the prevalence and pattern of lipid abnormalities in Nigerians with types I and 2 DM. METHODS A total of 600 patients with DM aged between 22 - 79 years were evaluated for lipid abnormalities. The anthropometric indices, glycosylated haemoglobin, pattern of DM treatment and co-morbidities were noted. Total cholesterol (TCHOL), triglyceride (TG), high density lipoproteins (HDL-C), low density lipoproteins cholesterol (LDL-C) levels and the atherogenic indices levels were documented. Test statistic used included student's t test and chi2. RESULTS Well over half (89%) of the study subjects had lipid abnormalities and there was no statistically significant difference in the proportions of subjects with type 1 and 2 DM with lipid abnormalities. Elevated LDL-C, TCHOL, TG and reduced HDL-C were noted in 74%, 42%, 13%, and 53% respectively of the study subjects. The commonly noted combined lipid abnormalities were elevated TG and reduced HDL-C. Hypertension, significant histories of smoking and alcohol ingestion were found to be potential determinants of the occurrence of dyslipidaemia. Age, sex, type of DM and anthropometric indices were found to be determinants of the the pattern of dyslipidaemia. Only a small proportion - (8%)-of the subjects with dyslipidaemia were on treatment for it. CONCLUSION Having defined the scope of dyslipidaemia in our patients and also highlighting its gross undertreatment, we hope that our data will help sensitize health care practitioners on screening for and treating dyslipidaemia. Elevated LDL-C and reduced HDL-C should be the primary targets of treatment in our patients with dyslipidaemia.

Abstract
Type 1 diabetes (T1D) is a common disease of childhood with a current prevalence of almost 2 cases per 1000 adolescents, according to the third National Health and Nutrition Examination Survey. Modern insulin treatment has resulted in improved quality of life for children with this chronic disorder. However, T1D continues to carry a long-term burden of increased microvascular and macrovascular complications and mortality risk. Compared to the nondiabetic population, patients with T1D are more likely to have >or=1 cardiovascular risk factor and often at an earlier age. Since the prevalence of cardiovascular risk factors increases with age in young persons with T1D, there is a clear need for early screening and counseling to prevent their occurrence and manage long-term health ramifications. The purpose of this review is to describe how traditional risk factors for cardiovascular disease such as an abnormal lipid profile, hypertension, obesity, and insulin resistance contribute to the accelerated atherosclerosis seen in young persons with T1D. A summary is given of the guidelines and recommendations published for clinical care for these patients.

Abstract
Data on dyslipidemia in type 1 diabetes is scarce. The authors aimed to evaluate the lipid profile in patients with type 1 diabetes and its correlation to glycemic control. Ninety-four subjects (53.2% males), aged 15.4+/-4.7 (3.6-21.9 years), with disease duration of 5.0+/-3.6 years (0.3-17 years) were evaluated for heart rate, blood pressure, height, and weight. Laboratory data included total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL), triglycerides (TGs), glycemia, glycosylated hemoglobin (HbA1c), creatinine, thyroid-stimulating hormone, antithyroid antibodies, and 24-hour microalbuminuria. Correlations were performed by the Spearman rank correlation test, and the significance level was <0.05. Mean values were TC, 168.6+/-46.6 mg/d; HDL, 43.1+/-15.3 mg/dL; LDL, 110.9+/-40.6 mg/dL; TGs, 78.3+/-48.6 mg/dL; glycemia, 204.6+/-116.7 mg/dL; and HbA1c, 11.2%+/-2.9%. High TC (43.9% vs. 10.7%; p<0.002) and LDL (51.5% vs. 10.7%; p<0.01) were more prevalent in patients 19 years and younger (n=66). HbA1c correlated with TC (r=0.30; p=0.004), LDL (r=0.28; p=0.008), TG (r=0.31; p=0.003), and TG/HDL ratio (r=0.25; p=0.01). Duration of diabetes correlated with LDL (r=0.21; p=0.04) and insulin daily doses with TG (r=0.23; p=0.04) and body mass index expressed as z scores (r=-0.28; p=0.007). There was a high prevalence of hypercholesterolemia (54.6%) in these diabetic patients, and lipid fraction levels were correlated with HbA1c. Good management of diabetes seems to be of paramount importance in controlling dyslipidemia.

Abstract
BACKGROUND Epidemiological studies suggest that dyslipidemia is an independent risk factor for the development of renal insufficiency in otherwise healthy individuals. Yet, data on the effect of cholesterol reduction are lacking in this population. We performed a secondary analysis of a large existing cohort to determine whether treatment with cholestyramine improved renal function compared with placebo. METHODS A total of 3,603 middle-aged men from the Lipid Research Clinics Coronary Primary Prevention Trial comprised the study group: 1,806 men were randomly assigned to treatment with cholestyramine, and 1,797 men, placebo. The primary outcome is difference in glomerular filtration rates between the 2 groups. RESULTS A total of 1,806 men were randomly assigned to treatment with cholestyramine, and 1,797 men, placebo. For the entire group, the estimated mean difference in glomerular filtration rates between the cholestyramine and placebo groups was 0.39 mL/min/1.73 m2 (0.007 mL/s/1.73 m2; P = 0.28) during a follow-up period of more than 8 years. CONCLUSION Cholesterol reduction with cholestyramine treatment did not meaningfully affect renal function compared with placebo in the present analysis. Prospective intervention trials are needed to determine whether decreasing serum cholesterol levels benefits kidney function in otherwise healthy individuals.

Abstract
AIMS/HYPOTHESIS Type 1 diabetic subjects are at increased risk of cardiovascular disease and exhibit multiple qualitative abnormalities of apolipoprotein (apo) B100-containing lipoproteins. This stable isotope kinetic experiment was designed to study whether these abnormalities are associated with changes in the synthesis and fractional catabolic rates of VLDL-, IDL- and LDL-apoB100. METHODS Using a bolus followed by a 16-h constant infusion of 13C-leucine, we performed a kinetic study in eight men with type 1 diabetes treated with a continuous subcutaneous insulin infusion administered by an external pump and in seven healthy men, in the fed state. RESULTS The mean HbA1c level in the type 1 diabetic patients was 8.00+/-1.48%. Plasma triglyceride, and total, LDL and HDL cholesterol levels were similar in patients and control subjects. VLDL were less triglyceride rich in type 1 diabetic patients than in control subjects (VLDL triglyceride : apoB 6.91+/-0.81 vs 8.29+/-1.24 mmol/g, p=0.05). Conversely, the IDL and LDL of the type 1 diabetic patients contained relatively higher levels of triglycerides (IDL triglycerides : apoB 2.16+/-0.36 vs 1.57+/-0.30 mmol/g, p<0.01; LDL triglycerides : apoB 0.27+/-0.06 vs 0.16+/-0.04 mmol/g, p<0.05). The apoB100 pool size, production and fractional catabolic rates in the two groups of subjects were similar for all lipoprotein fractions. CONCLUSIONS/INTERPRETATION Despite qualitative abnormalities, especially abnormalities of triglyceride content, the metabolism of apoB100-containing lipoproteins is not altered in type 1 diabetic men with fair glycaemic control with continuous subcutaneous insulin infusion. The high risk of atherosclerosis in these patients cannot be explained by kinetic abnormalities of apoB100-containing lipoproteins.

Abstract
OBJECTIVE Dyslipidemia is a preventable major risk factor for coronary heart disease (CHD). Despite an increased risk of CHD in type 1 diabetes, little is known concerning awareness and adequacy of dyslipidemia treatment in this population. In this report, we describe the prevalence of dyslipidemia and adequacy of pharmacological treatment in patients with type 1 diabetes and comparable nondiabetic subjects. RESEARCH DESIGN AND METHODS From 2000 to 2002, the Coronary Artery Calcification in Type 1 Diabetes study obtained fasting lipid profiles in 1,416 individuals aged 19-56 years with no history of CHD: 652 type 1 diabetic patients (46% men, mean age 37 +/- 9 years) and 764 nondiabetic control subjects (50% men, mean age 39 +/- 9 years). These data combined with patient questionnaire results were used to determine prevalence of dyslipidemia and adequacy of pharmacological treatment. For all subjects, dyslipidemia was defined using National Cholesterol Education Program Adult Treatment Panel III criteria. RESULTS Type 1 diabetic subjects had significantly less dyslipidemia than nondiabetic control subjects (47 vs. 58%, P < 0.001), and a higher percentage of those with abnormal lipids were aware of (52 vs. 34%, P < 0.0001), on medication for (36 vs. 9%, P < 0.0001), and in control of their lipid levels (15 vs. 1.4%, P < 0.001). Of those on treatment, control was achieved in 41% of type 1 diabetic subjects and 15% of nondiabetic participants (P < 0.01). CONCLUSIONS Dyslipidemia, a major risk factor for CHD, remains largely undiagnosed and undertreated in high-risk populations, such as patients with type 1 diabetes.

Abstract
Atherosclerotic cardiovascular diseases are the major causes of morbidity and mortality in patients with diabetes mellitus. Both quantitative and qualitative abnormalities of lipo-proteins are associated with the development of atherogenesis. In this study, the prevalence of dyslipidemia and the relative levels of glycosylated lipoproteins in 20 children and adolescents with type 1 diabetes mellitus were determined. Lipid profile, apolipoproteins A-I and B, Lp(a) and LpA-I in plasma were assayed. LpB and glycosylated HDL and LDL were evaluated by ELISA. Diabetic patients and controls had normal lipid profiles, but the diabetic group showed significantly higher LpA-I and lower LpA-I:A-II concentrations than controls. The diabetic group showed a significantly higher glycosylation level of HDL than controls and did not show a statistical difference for glycosylated LDL. No significant correlation between glycosylated lipoproteins, glycemia or HbA1c was found. In conclusion, these results suggest that type 1 diabetic patients develop important qualitative lipid abnormalities.

Abstract
The current study sought to assess the effect of improving glycemic control in type 2 diabetes on the components of diabetic dyslipidemia, especially low-density lipoprotein (LDL) size. A total of 33 type 2 diabetic patients (48.5% women, age 59.6 +/- 11.1 years, body mass index [BMI] 28.9 +/- 4.9, diabetes duration 6 [0 to 40] years, 40.7% on insulin) were seen at the hospital because of poor glycemic control (hemoglobin A(1c) [HbA(1c)] 10.33% +/- 1.89%). Triglyceride, LDL-cholesterol (LDLc, Friedewald/ ultracentrifugation), high-density lipoprotein HDL-cholesterol (HDLc, direct method), apolipoproteins AI (apoAI) and B (apoB) (immunoturbidimetry), and LDL size (gradient gel electrophoresis) were measured at baseline and after improvement in glycemic control (decrease >/= 1 percentage point in HbA(1c) and final HbA(1c) </= 8%). Improvement in glycemic control (HbA(1c) 7.01% +/- 0.63%, P <.0005 v baseline) after a follow-up of 3.5 (range, 1 to 13) months resulted in a significant reduction in LDLc (3.34 +/- 1.02 v 3.62 +/- 1.15 mmol/L, P <.05) and apoB (1.07 +/- 0.25 v 1.17 +/- 0.29 g/L, P <.01) and an increase in HDLc (1.21 +/- 0.32 v 1.13 +/- 0.34 mmol/L, P <.05) and apoAI (1.36 +/- 0.24 v 1.27 +/- 0.24 mmol/L, P < 0.01) in the whole group, and an increase in LDL particle size (25.61 +/- 0.53 v 25.10 +/- 0.31 nm, P <.005) in the 14 patients showing LDL phenotype B at baseline. No significant changes were seen in body weight or BMI. We conclude that improvement of glycemic control in type 2 diabetes improves most of the components of diabetic dyslipidemia, including a shift towards larger LDL particles in subjects with phenotype B.

Abstract
Evidence for the effectiveness of lipid-lowering therapy in reducing CHD risk continues to emerge. In primary prevention, clinical trials have demonstrated a benefit for middle-aged, high-risk men with high LDL cholesterol and, more recently, for men and women with "average" LDL and low HDL cholesterol. Although low HDL cholesterol, small dense LDL particles, elevated lipoprotein (a), elevated apolipoprotein B, and the dyslipidemia of the metabolic syndrome pose an increased in CHD risk in some patients, the risk reduction with lipid-lowering therapy has not been fully investigated. The CHD risk of isolated hypertriglyceridemia remains uncertain. Very high triglyceride levels, however, should be treated to prevent pancreatitis. A lipid-lowering diet and other appropriate lifestyle changes constitute safe advice for all patients with dyslipidemia. In initiating pharmacologic therapy, physicians should view potential risk reduction in the context of a patient's overall CHD risk. The selection of particular medications can be individualized, considering effectiveness evidence from clinical trials, lipid-lowering potency, adverse effects, drug interactions, costs, and patient preferences.

Abstract
OBJECTIVE Persons with HIV infection develop metabolic abnormalities related to their antiretroviral therapy and HIV infection itself. The objective of this study was to summarize the emerging evidence for the incidence, etiology, health risks, and treatment of dyslipidemias in HIV disease. DESIGN Systematic review of original research with quantitative synthesis. MAIN RESULTS Dyslipidemia is common in persons with HIV infection on highly active antiretroviral therapy (HAART), but methodologic differences between studies preclude precise estimates of prevalence and incidence. The typical pattern includes elevated total cholesterol, low-density lipoprotein cholesterol, and triglycerides, which may be markedly elevated. The dyslipidemia may be associated with lipodystrophy, insulin resistance, and, rarely, frank diabetes mellitus. Exposure to protease inhibitors (PIs) is associated with this entire range of metabolic abnormalities. PI-naïve patients on nucleoside reverse transcriptase inhibitors (NRTIs) may develop lipodystrophy, insulin resistance, hypercholesterolemia, and possibly modest elevations in triglycerides but not severe hypertriglyceridemia, which appears to be linked to PIs alone. Most studies have not found an association between CD4 lymphocyte count or HIV viral load and lipid abnormalities. The pathogenesis is incompletely understood and appears to be multifactorial. There are insufficient data to definitively support an increased coronary heart disease risk in patients with HIV-related dyslipidemia. However, some of the same metabolic abnormalities remain firmly established risk factors in other populations. Patients on HAART with severe hypertriglyceridemia may develop pancreatitis or other manifestations of the chylomicronemia syndrome. Some of the metabolic derangements (particularly hypertriglyceridemia) may improve upon replacing a PI with a non-nucleoside reverse transcriptase inhibitor. The limited experience suggests that fibrates, pravastatin, and atorvastatin can safely treat lipid abnormalities in HIV-infected patients. CONCLUSIONS Patients with HIV infection on HAART should be screened for lipid disorders, given their incidence, potential for morbidity, and possible long-term cardiovascular risk. Treatment decisions are complex and must include assessments of cardiac risk, HIV infection status, reversibility of the dyslipidemia, and the effectiveness and toxicities of lipid-lowering medications. The multiple potential drug interactions with antiretroviral or other HIV-related medications should be considered in lipid-lowering drug selection and monitoring.

Abstract
Low HDL cholesterol is a frequent cardiovascular risk factor in diabetes. Because of its pivotal role for the regulation of HDL plasma levels, we investigated in vivo and in vitro regulation of the ATP-binding cassette transporter A1 (ABCA1) by insulin and metabolites accumulating in diabetes. Compared with euglycemic control mice, ABCA1 gene expression was severely decreased in the liver and peritoneal macrophages of diabetic mice. Treatment with insulin restored this deficit. Incubation of cultivated HepG2 hepatocytes and RAW264.7 macrophages with unsaturated fatty acids or acetoacetate, but not with insulin, glucose, saturated fatty acids, or hydroxybutyrate, downregulated ABCA1 mRNA and protein. The suppressive effect of unsaturated fatty acids and acetoacetate became most obvious in cells stimulated with oxysterols or retinoic acid but was independent of the expression of the thereby regulated transcription factors liver-X-receptor alpha (LXRalpha) and retinoid-X-receptor alpha (RXRalpha), respectively. Unsaturated fatty acids and acetoacetate also reduced ABCA1 promotor activity in RAW264.7 macrophages that were transfected with a 968-bp ABCA1 promotor/luciferase gene construct. As the functional consequence, unsaturated fatty acids and acetoacetate inhibited cholesterol efflux from macrophages. Downregulation of ABCA1 by unsaturated fatty acids and acetoacetate may contribute to low HDL cholesterol and increased cardiovascular risk of diabetic patients.

Abstract
OBJECTIVE Treating dyslipidemia in diabetic patients is essential, particularly among minority populations with increased risk of complications. Because little is known about the impact of outpatient diabetes management on lipid outcomes, we examined changes in lipid profiles in urban African-Americans who attended a structured diabetes care program. RESEARCH DESIGN AND METHODS A retrospective analysis of initial and 1-year follow-up lipid values was conducted among patients selected from a computerized registry of an urban outpatient diabetes clinic. The independent effects of lipid-specific medications, glycemic control, and weight loss on serum total cholesterol, LDL cholesterol, HDL cholesterol, and triglyceride levels were evaluated by analysis of covariance and multiple linear regression. RESULTS In 345 patients (91% African-American and 95% with type 2 diabetes), HbA(1c) decreased from 9.3% at the initial visit to 8.2% at 1 year (P < 0.001); total and LDL cholesterol and triglyceride levels were significantly lower, and HDL cholesterol was higher. After stratifying based on use of lipid-specific therapy, different outcomes were observed. In 243 patients not taking dyslipidemia medications, average total cholesterol, LDL cholesterol, and triglyceride concentrations at 1 year were similar to initial values, whereas in 102 patients receiving pharmacotherapy, these lipid levels were all lower at 1 year relative to baseline (P < 0.001). Mean HDL cholesterol increased regardless of lipid treatment status (P < 0.001). After adjusting for other variables, changes in LDL cholesterol concentration were associated only with use of lipid-specific agents (P = 0.003), whereas improved HbA(1c) and weight loss had no independent effect. Lipid therapy, improved glycemic control, and weight loss were not independently related to changes in HDL cholesterol and therefore could not account for the positive changes observed. Use of lipid-directed medications, improvement in glycemic control, and weight loss all resulted in significant declines in triglyceride levels but only improved HbA(1c) and weight loss had an independent effect. CONCLUSIONS Among urban African-Americans, diabetes management led to favorable changes in HDL cholesterol and triglyceride levels, but improved glycemic control and weight loss had no independent effect on LDL cholesterol concentration. Initiation of pharmacologic therapy to treat high LDL cholesterol levels should be considered early in the course of diabetes management to reach recommended targets and reduce the risk of cardiovascular complications in this patient population.
