ABSTRACT
OBJECTIVES: Investigation of the comorbidity burden in persons with multiple sclerosis (PwMS) has become increasingly important. The aim of this study was to investigate the relationships of cardiovascular disease (CVD) comorbidities and type 2 diabetes with the disability progression. MATERIALS & METHODS: The retrospective cohort study was conducted at the Clinic of Neurology, Belgrade. The Belgrade MS population Registry, which comprises 2725 active MS cases, was used as the source of data. The mean duration of the disease was 21.6 ± 12.5 years. Expanded Disability Status Scale (EDSS) was followed in all PwMS in the Registry. In the statistical analysis, the Cox proportional hazard regression analysis and Kaplan-Meier curve were performed. RESULTS: Hypertension statistically significantly contributed to more rapid reaching investigated levels of irreversible disability (EDSS 4.0, 6.0, and 7.0), while the presence of any of the investigated CVD comorbidities and type 2 diabetes significantly contributed to faster reaching EDSS 4.0 and EDSS 6.0. In a multivariable model, progression index (PI) was singled out (HR = 3.171, p < .001), indicating that higher progression index (PI) was an independent predictor of CVD occurrence in MS patients. In the case of type 2 diabetes, PI (p < .001) and MS phenotype (p = .015) were statistically significant in multivariable Cox regression analysis. CONCLUSIONS: Our study confirms the impact of CVD comorbidities and type 2 diabetes in MS on the progression of disability as measured by EDSS in the large cohort of PwMS from the population Registry.

Therapeutic apheresis (TA) is prescribed to patients that suffer from a severe progressive disease that is not sufficiently treated by conventional medications. A way to gain more knowledge about this treatment is usually by the local analysis of data. However, the use of large quality assessment registries enables analyses of even rare findings. Here, we report some of the recent data from the World Apheresis Association (WAA) registry. Data from >104,000 procedures were documented, and TA was performed on >15,000 patients. The main indication for TA was the collection of autologous stem cells (45% of patients) as part of therapy for therapy. Collection of stem cells from donors for allogeneic transplantation was performed in 11% of patients. Patients with indications such as neurological diseases underwent plasma exchange (28%). Extracorporeal photochemotherapy, lipid apheresis, and antibody removal were other indications. Side effects recorded in the registry have decreased significantly over the years, with approximately only 10/10,000 procedures being interrupted for medical reasons. CONCLUSION: Collection of data from TA procedures within a multinational and multicenter concept facilitates the improvement of treatment by enabling the analysis of and feedback on indications, procedures, effects, and side effects.
ABSTRACT
Type 2 diabetes (T2D), one of the most prevalent noncommunicable diseases, is often preceded by insulin resistance (IR), which underlies the inability of tissues to respond to insulin and leads to disturbed metabolic homeostasis. Mitochondria, as a central player in the cellular energy metabolism, are involved in the mechanisms of IR and T2D. Mitochondrial function is affected by insulin resistance in different tissues, among which skeletal muscle and liver have the highest impact on whole-body glucose homeostasis. This review focuses on human studies that assess mitochondrial function in liver, muscle and blood cells in the context of T2D. Furthermore, different interventions targeting mitochondria in IR and T2D are listed, with a selection of studies using respirometry as a measure of mitochondrial function, for better data comparison. Altogether, mitochondrial respiratory capacity appears to be a metabolic indicator since it decreases as the disease progresses but increases after lifestyle (exercise) and pharmacological interventions, together with the improvement in metabolic health. Finally, novel therapeutics developed to target mitochondria have potential for a more integrative therapeutic approach, treating both causative and secondary defects of diabetes.

AIMS/HYPOTHESIS: Experimental studies suggest that the fatty acid palmitoleate may act as an adipocyte-derived lipid hormone (or 'lipokine') to regulate systemic metabolism. We investigated the relationship of circulating palmitoleate with insulin sensitivity, beta cell function and glucose tolerance in humans. METHODS: Plasma NEFA concentration and composition were determined in non-diabetic individuals from the Relationship between Insulin Sensitivity and Cardiovascular disease (RISC) study cohort at baseline (n = 1234) and after a 3 year follow-up (n = 924). Glucose tolerance, insulin secretion and beta cell function were assessed during an OGTT. Whole-body insulin sensitivity was measured by a hyperinsulinaemic-euglycaemic clamp (M/I) and OGTT (oral glucose insulin sensitivity index [OGIS]). The liver insulin resistance index was calculated using clinical and biochemical data. Body composition including fat mass was determined by bioelectrical impedance. RESULTS: Circulating palmitoleate was proportional to fat mass (r = 0.21, p < 0.0001) and total NEFA levels (r = 0.19, p < 0.0001). It correlated with whole-body insulin sensitivity (M/I: standardised regression coefficient [std. ß] = 0.16, p < 0.0001), liver insulin resistance (std. ß = -0.14, p < 0.0001), beta cell function (potentiation: std. ß = 0.08, p = 0.045) and glucose tolerance (2 h glucose: std. ß = -0.24, p < 0.0001) after adjustment for age, sex, BMI, adiposity and other NEFA. High palmitoleate concentrations prevented the decrease in insulin sensitivity associated with excess palmitate (p = 0.0001). In a longitudinal analysis, a positive independent relationship was observed between changes in palmitoleate and insulin sensitivity over time (std. ß = 0.07, p = 0.04). CONCLUSIONS/INTERPRETATION: We demonstrated that plasma palmitoleate is an independent determinant of insulin sensitivity, beta cell function and glucose tolerance in non-diabetic individuals. These results support the role of palmitoleate as a beneficial lipokine released by adipose tissue to prevent the negative effects of adiposity and excess NEFA on systemic glucose metabolism.

BACKGROUND: Hyperglycemia has detrimental effect on ischemic myocardium, but the impact of acute hyperglycemia on the myocardium in asymptomatic diabetic patients has not been fully elucidated. Thus, this follow-up study was aimed to investigate the effects and reversibility of acute hyperglycemia on regional contractile function of left ventricle (LV) in diabetic patients without cardiovascular disease. METHODS: The two-dimensional speckle tracking echocardiography (2D-STE), including multilayer strain analysis, was used for evaluation of global and regional LV function in asymptomatic, normotensive patients with uncomplicated diabetes, with acute hyperglycemia ( ≥ 11.1 mmol/l) (Group A, n = 67), or with optimal metabolic control (fasting plasma glucose < 7 mmol/l and HbA1c < 7%) (Group B, n = 20), while 20 healthy individuals served as controls (Group C). In group A, after 72 h of i.v. continuous insulin treatment (at the time euglycemia was achieved) (second examination) and after 3 months following acute hyperglycemia (third examination) 2D-STE was repeated. RESULTS: Global longitudinal strain (GLS) (- 19.6 ± 0.4%) in Group A was significantly lower in comparison to both groups B (- 21.3 ± 0.4%; p < 0.05) and C (- 21.9 ± 0.4%; p < 0.01) at baseline, while we could not detect the differences between groups B and C. Peak systolic longitudinal endocardial (Endo), mid-myocardial (Mid) and epicardial (Epi) layer strain were significantly lower in group A at baseline compared to both groups B and C. Deterioration in peak systolic circumferential strain was observed at basal LV level, in all three layers (Endo, Mid and Epi) and in mid-cavity LV level in Epi layer in group A in comparison to group C. Moreover, in group A, after euglycemia was achieved (at second and third examination) GLS, as well as peak longitudinal and circumferential strain remain the same. CONCLUSION: Acute hyperglycemia in asymptomatic diabetic patients has significant negative effects on systolic LV myocardial mechanics primarily by reducing GLS and multilayer peak systolic longitudinal and circumferential strain which was not reversible after three months of good glycemic control.

EMPA-REG OUTCOME is recognised by international guidelines as a landmark study that showed a significant cardioprotective benefit with empagliflozin in patients with type 2 diabetes (T2D) and cardiovascular disease. To assess the impact of empagliflozin in routine clinical practice, the ongoing EMPRISE study is collecting real-world evidence to compare effectiveness, safety and health economic outcomes between empagliflozin and DPP-4 inhibitors. A planned interim analysis of EMPRISE was recently published, confirming a substantial reduction in hospitalisation for heart failure with empagliflozin across a diverse patient population. In this commentary article, we discuss the new data in the context of current evidence and clinical guidelines, as clinicians experienced in managing cardiovascular risk in patients with T2D. We also look forward to what future insights EMPRISE may offer, as evidence is accumulated over the next years to complement the important findings of EMPA-REG OUTCOME.

PURPOSE OF REVIEW: Familial hypercholesterolemia (FH) is often perceived and described as underdiagnosed and undertreated, though effective treatment of FH is available. Owing to the mentioned facts, it is ever more imperative to screen and treat FH patients. Subsequent to the identification of patients, the project focuses on the improvement of their prognoses. The ScreenPro FH project was established as a functional international network for the diagnosis, screening, and treatment of FH. Individual countries were assigned goals, e.g., to define the actual situation and available treatment. With "central support," more centers and countries participated in the project. Subsequently, individual countries reported the results at the beginning and end of the project. Collected data were statistically evaluated. RECENT FINDINGS: The increasing number of patients in databases, from 7500 in 2014 to 25,347 in 2018, demonstrates the improvement in overall effectiveness, as well as an increase in the number of centers from 70 to 252. Before all, LDL-C decreased by 41.5% and total cholesterol by 32.3%. As data from all countries and patients were not available at the time of the analysis, only those results from 10 countries and 5585 patients at the beginning of the project and at the time of writing are included. Our data are quite positive. However, our results have only limited validity. Our patients are far from the target levels of LDL-C. The situation can be improved with the introduction of new therapy, PCSK9-i, evolocumab, and alirocumab. International cooperation improved the screening of FH and finally led to an improvement in cardiovascular risk.

BACKGROUND: For patients with type 2 diabetes (T2D), cardiovascular disease (CVD) is the single most common cause of mortality. In 2008 and 2012, the Federal Drug Administration (FDA) and the European Medicines Agency (EMA) respectively mandated cardiovascular outcomes trials (CVOTs) on all new anti-diabetic agents, as prospective trials statistically powered to rule out excess cardiovascular risk in patients with T2D. Unexpectedly, some of these CVOTs have demonstrated not only cardiovascular safety, but also cardioprotective effects, as was first shown for the SGLT2 inhibitor empagliflozin in EMPA-REG OUTCOME. EXPERT OPINION: To debate newly available CVOT data and to put them into context, we convened as a group of medical experts from the Central and Eastern European Region. Here we describe our discussions, focusing on the conclusions we can draw from EMPA-REG OUTCOME and other SGLT2 inhibitor CVOTs, including when considered alongside real-world evidence. CONCLUSION: CVOTs investigating SGLT2 inhibitors have suggested benefits beyond glucose lowering that have been confirmed in real-world evidence studies.

The 3rd Cardiovascular Outcome Trial Summit of the Diabetes & Cardiovascular Disease EASD Study Group was held on the 26-27 October 2017 in Munich. As in 2015 and 2016, this summit was organised in light of recently completed and published CVOTs on diabetes, aiming to serve as a reference meeting for in-depth discussions on the topic. Amongst others, the CVOTs EXSCEL, DEVOTE, the CANVAS program and the ACE-trial, which released primary outcome results in 2017, were discussed. Trial implications for diabetes management and recent perspectives of diabetologists, cardiologists, endocrinologists, nephrologists and general practitioners were highlighted. The clinical relevance of cardiovascular outcome trials and its implications regarding reimbursement were compared with real-world studies. The 4th Cardiovascular Outcome Trial Summit will be held in Munich 25-26 October 2018 ( http://www.dcvd.org ).

BACKGROUND: People with chronic renal disease are insulin resistant. We hypothesized that in a healthy population, baseline renal function is associated with insulin sensitivity three years later. METHODS: We studied 405 men and 528 women from the European Group for the study of Insulin Resistance - Relationship between Insulin Sensitivity and Cardiovascular disease cohort. Renal function was characterized by the estimated glomerular filtration rate (eGFR) and by the urinary albumin-creatinine ratio (UACR). At baseline only, insulin sensitivity was quantified using a hyperinsulinaemic-euglycaemic clamp; at baseline and three years, we used surrogate measures: the Matsuda insulin sensitivity index (ISI), the HOmeostasis Model Assessment of Insulin Sensitivity (HOMA-IS). Associations between renal function and insulin sensitivity were studied cross-sectionally and longitudinally. RESULTS: In men at baseline, no associations were seen with eGFR, but there was some evidence of a positive association with UACR. In women, all insulin sensitivity indices showed the same negative trend across eGFR classes, albeit not always statistically significant; for UACR, women with values above the limit of detection, had higher clamp measured insulin sensitivity than other women. After three years, in men only, ISI and HOMA-IS showed a U-shaped relation with baseline eGFR; women with eGFR> 105 ml/min/1.73m2 had a significantly higher insulin sensitivity than the reference group (eGFR: 90-105 ml/min/1.73m2). For both men and women, year-3 insulin sensitivity was higher in those with higher baseline UACR. All associations were attenuated after adjusting on significant covariates. CONCLUSIONS: There was no evidence to support our hypothesis that markers of poorer renal function are associated with declining insulin sensitivity in our healthy population.

BACKGROUND: Galectin-3 is a protein widely distributed in the heart, brain and blood vessels, and has a regulatory role in inflammation, immunology and cancer. Many studies demonstrated that the increased level of galectin-3 is associated with progressive fibrosis and stiffening of the myocardium. The aim of this study was to investigate the role of galectin-3 in patients with type 2 diabetes (T2D) and/or arterial hypertension (HT). METHODS: Study population included 189 patients, with no coronary artery disease, divided into three groups: group 1 (T2D), group 2 (T2D+HT), and group 3 (HT). All subjects underwent routine laboratory tests, as well as specific biomarkers assessment [galectin-3, glycosylated hemoglobin (HbA1c), N- terminal fragment B-type natriuretic peptide (NT-proBNP)]. Cardiological evaluation included physical examination, transthoracic tissue Doppler echocardiography and stress echocardiography. RESULTS: The results of this study demonstrated significantly increased levels of galectin-3, blood glucose, and HbA1c in group 2. Also, echocardiographicaly, left ventricular (LV) diameters and IVS thickness were increased in this group of patients. Furthermore, in the same cohort a positive correlation between galectin-3 and NT-pro BNP, and galectin-3 and LV mass were demonstrated. In addition, a negative correlation between galectin-3 and LV end-diastolic diameter was revealed. CONCLUSIONS: This study revealed that levels of galectin-3 were higher in patients with both T2D and HT, and correlated with LV mass, indicating the potential role of this biomarker for early detection of myocardial structural and functional alterations.

AIMS: This systematic review was aimed to assess the association between magnitude of body weight loss (BWL) in type 2 diabetes (T2D) patients and cardiovascular (CV) risk in CV outcome trials (CVOTs). METHODS: We searched electronic databases (PubMed, Cochrane and Scopus) for available CVOTs, observational cohort studies or post hoc analyses of clinical trials of adult T2D patients investigated the association of BWL with CV outcomes and/or all-cause mortality. RESULTS: 19 RCTs of novel glucose-lowering drugs (GLP-1RA, DPP-4i and SGLT2i) and 6 RCT or observational trial of different strategies (intensive treatment or standard care) were included (379.904 T2D patients). Higher BWL during GLP-1RA treatment, in comaprison to lower BWL, was associated with higher decrease in risk of MACE, while DPP-4i had not that effect. With SGLT2i the higher decrease in risk of MACE was associated with lower BWL. In contrast, in other different strategies, higher BWL lead to increase in risk for MACE and all-cause mortality. CONCLUSIONS: In CVOTs, treatment of T2D patients resulted in BWL, which correlated with reduction in risk for CV outcomes, particularly with GLP-1 RAs. However, interventional non-CVOTs are warning that in the absence of structured behavioral intervention and relevant medication, the large BWL might be harmful for CV outcomes.

Type 2 diabetes (T2D) is associated with increased risk for chronic kidney disease (CKD). It is estimated that 40 % of people with diabetes have CKD, which consequently leads to increase in morbidity and mortality from cardiovascular diseases (CVDs). Diabetic kidney disease (DKD) is leading cause of CKD and end-stage renal disease (ESRD) globally. On the other hand, DKD is independent risk factor for CVDs, stroke and overall mortality. According to the guidelines, using spot urine sample and assessing urine albumin-to-creatinine ratio (UACR) and estimated glomerular filtration rate (eGFR) are both mandatory methods for screening of CKD in T2D at diagnosis and at least annually thereafter. Diagnosis of CKD is confirmed by persistent albuminuria followed by a progressive decline in eGFR in two urine samples at an interval of 3 to 6 months. However, many patients with T2D remain underdiagnosed and undertreated, so there is an urgent need to improve the screening by detection of albuminuria at all levels of health care. This review discusses the importance of albuminuria as a marker of CKD and cardiorenal risk and provides insights into the practical aspects of methods for determination of albuminuria in routine clinical care of patients with T2D.

INTRODUCTION: Previous gestational diabetes (pGD) is associated with a high risk of postpartum dyslipidemia (pD). Our study was aimed at investigating the prevalence of pD and estimating the risk for pD based on metabolic pregnancy parameters in normoglycemic women with pGD. METHODS: 147 women with pGD and normoglycemia after delivery were divided into groups: A (n = 63) with pD and B (n = 84) with normal lipids, defined by the National Cholesterol Education Program's Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults (Adult Treatment Panel III) Final Report (NCEP ATP III). We recorded age, body mass index (BMI) at conception, fasting glucose (FG), HbA1c, total cholesterol (TC), triglycerides (Tg), low-density lipoprotein (LDL-c), and high-density lipoprotein cholesterol (HDL-c) measured mid-pregnancy and 1-6 months after delivery. GD was diagnosed by 2 h oral glucose tolerance test (OGTT) between the 24th and the 28th week of gestation, which was repeated after delivery to confirm normoglycemia. RESULTS: 42.8% had pD (group A) while 57.2% had normal lipids (group B). Group A was older (36.8 ± 2.7) than B (33.0 ± 4.2 years, p < 0.001) and had a higher BMI (A 31.2 ± 6.4 vs. B 25.5 ± 2.4 kg/m2, p < 0.001). Simultaneously, HbA1c and FG were higher in group A (5.4 ± 0.3, 5.1 ± 0.4) than B (5.2 ± 0.0%, p = 0.001; 4.8 ± 0.0 mmol/L, p < 0.001). Also, group A had higher TC, LDL-c, and Tg [6.6 (6.1-6.9); 4.2 ± 0.4; 2.9 ± 0.8] compared to B [6.2 (5.4-6.9), p < 0.001; 3.4 ± 0.9, p = 0.001; 2.5 ± 0.6, p < 0.001], while the two groups had comparable HDL-c (A: 1.2 ± 0.3 vs. B: 1.2 ± 0.2 mmol/L, p = 0.998). Calculating the cutoff for age, BMI, HbA1c, FG, LDL-c, and Tg (> 35 years, 26.4 kg/m2, 5.2%, 4.8, 3.9 and 2.7 mmol/L, respectively), univariate regression analysis showed a difference for each (p < 0.001). Allocating 1 point to each predictor, we developed ALOHa G score, which showed high accuracy (AUC 0.931, p < 0.001) for risk of pD in normoglycemic women with pGD. According to the ALOHa-G score, more women in group A were at high risk (≥ 4) and medium risk (= 3) (61.9; 34.9) for pD than in group B (4.8; 14.3), with a lower percentage at low risk for PD (≤ 2) in group A than in group B (3.2 vs. 81.0%). CONCLUSION: Our results implied a remarkable occurrence of pD in normoglycemic women with pGD. Also, the ALOHa-G score was developed based on pregnancy metabolic predictors and could be used to identify normoglycemic women with pGD who are at high risk for pD.
ABSTRACT
The aim of this study was to analyze the trends in diabetes in pregnancy in Belgrade, Serbia for the period of the past decade and forecast the number of women with pre-gestational diabetes for the years 2030 and 2050. The study included the data on all pregnant women with diabetes from the registry of the deliveries in Belgrade, by the City Institute of Public Health of Belgrade, Serbia for the period between 2010 and 2020 and the published data on the deliveries on the territory of Belgrade. During the examined period the total number of live births in Belgrade was 196,987, and the prevalence of diabetes in pregnancy was 3.4%, with the total prevalence of pre-gestational diabetes of 0.7% and overall prevalence of GDM of 2.7%. The average age of women in our study was significantly lower in 2010 compared to 2020. The forecasted prevalence of pre-gestational diabetes among all pregnant women for 2030 is 2% and 4% for 2050 in our cohort. Our study showed that the prevalence of pre-gestational diabetes has increased both among all pregnant women and among women with diabetes in pregnancy in the past decade in Belgrade, Serbia and that it is expected to increase further in the next decades and to further double by 2050.

The aim of this study was to examine the differences in pregnancy complications, delivery characteristics, and neonatal outcomes between women with type 1 diabetes mellitus (T1DM), type 2 diabetes mellitus (T2DM), and gestational diabetes mellitus (GDM). This study included all pregnant women with diabetes in pregnancy in Belgrade, Serbia, between 2010 and 2020. The total sample consisted of 6737 patients. In total, 1318 (19.6%) patients had T1DM, 138 (2.0%) had T2DM, and 5281 patients (78.4%) had GDM. Multivariate logistic regression with the type of diabetes as an outcome variable showed that patients with T1DM had a lower likelihood of vaginal delivery (OR: 0.73, 95% CI: 0.64-0.83), gestational hypertension (OR: 0.47, 95% CI: 0.36-0.62), higher likelihood of chronic hypertension (OR: 1.88, 95% CI: 1.55-2.29),and a higher likelihood ofgestational age at delivery before 37 weeks (OR: 1.38, 95% CI: 1.18-1.63) compared to women with GDM. Multivariate logistic regression showed that patients with T2DM had a lower likelihood ofgestational hypertension compared to women with GDM (OR: 0.37, 95% CI: 0.15-0.92).Our results indicate that the highest percentage of diabetes in pregnancy is GDM, and the existence of differences in pregnancy complications, childbirth characteristics, and neonatal outcomes are predominantly between women with GDM and women with T1DM.

INTRODUCTION: Managing non-communicable diseases (NCDs) requires redesigning health care delivery to achieve better coordination of services at all levels of health care. The aim of this study was improving prevention and strengthening high quality of care for NCDs by using type 2 diabetes as a model disease. METHODS: The mix method approach served to analyse the impact of the intervention processes. Source of information were routine health statistics, interviews and observation. Key Performance Indicators in defined Improvement Areas assisted in the quality of diabetes care assessment. RESULTS AND DISCUSSION: During the study the National Diabetes Centre (NDC) was established. The NDC experts organized numerous educational events, 316 physicians and nurses have participated. New electronic data base was implemented in 20 pilot Primary Health Care Centres (PHCCs) with 38,833 electronic diabetes records. CONCLUSIONS: The intervention led to establishment of the NDC, strengthening competences of health care professionals and to the renewal of the Diabetes Care Units in PHCCs included in the study.

INTRODUCTION: Women with previous gestational diabetes (pGD) are at higher risk of prediabetes (PD) after delivery. The aim of this study was to determine the prevalence of and predictors for PD among women with pGD. METHODS: The study included 186 women with pGD treated by lifestyle modification. After delivery, the women were divided into group A (n = 80) with PD and group B (n = 106) with normal glucose tolerance (NGT), defined by the results of the 2-h oral glucose tolerance test at 4-12 weeks after delivery. We recorded age, body mass index (BMI) at conception and after delivery, fasting glucose (FG), glycated hemoglobin (HbA1c), total cholesterol (TC), triglycerides (Tg), low density lipoprotein cholesterol (LDL-c), high-density lipoprotein cholesterol (HDL-c) and the Tg/HDL-c ratio measured in the third trimester of pregnancy. RESULTS: Of the 186 women with pGD enrolled in the study, 43% showed prediabetes at 4-12 weeks after delivery, with 13.9% of these women showing impaired FG (IFG), 12.9% showing impaired glucose tolerance (IGT) and 16.2% with IFG/IGT. The groups differed in terms of age and BMI at conception and after delivery. In the third trimester of pregnancy, HbA1c was higher in women in group A than in those in group B (mean ± standard deviation: 5.6 ± 0.4 vs. 5.2 ± 0.3%; p < 0.001), while FG was comparable. Compared to women in group B, women in group A had higher TC (7.1 ± 0.8 vs. 6.6 ± 1.0 mmol/L), Tg (2.7 ± 0.9 vs. 2.1 ± 0.6 mmol/L) and LDL-c (4.7 ± 0.8 vs. 4.3 ± 1.0 mmol/L) (all p < 0.001), lower HDL-c (1.0 ± 0.2 vs. 1.4 ± 1.0; p < 0.001) and higher median Tg/HDL-c (5.4 [range 4.6-14.3] vs. 4.9 [range 1.1-11.5]; p < 0.001). Univariate analysis found an association between prediabetes and age, BMI at conception and after delivery, HbA1c, TC, LDL-c, HDL-c, Tg and Tg/HDL-c ratio. Of these variables, the multivariate analysis showed age (odds ratio [OR] 1.19; p < 0.001), HbA1c (OR 31.06; p < 0.001), Tg (OR 4.09; p < 0.001) and LDL-c (OR 2.00; p = 0.005) as predictors for prediabetes. CONCLUSION: High prevalence of early diagnosed PD in women with pGD was accompanied by advanced age and higher BMI at conception and after delivery. Moreover, age, HbA1c, Tg and LDL-c were predictors for PD.
ABSTRACT
We have recently shown an impairment in insulin sensitivity and insulin secretion in normoglycemic patients with Huntington disease (HD). To investigate whether such observations are HD-specific or may be common to other polyglutamine diseases, glucose homeostasis was studied in 12 unrelated, untreated normoglycemic patients with spinocerebellar ataxia type 1 (SCA1), another entity from the family of polyglutamine diseases, and 24 healthy, matched controls. Metabolic investigations included (a) glucose tolerance assessment on the basis of glucose curve during oral glucose challenge; (b) insulin sensitivity assessment by the homeostasis model assessment (HOMA) and the euglycemic insulin clamp (M value); and (c) insulin secretion by acute insulin response (AIR) and insulinogenic index. The evaluation of insulin sensitivity demonstrated higher HOMA-insulin resistance indices, and lower M values (P < 0.001 and P < 0.05, respectively), while both the AIR and the insulinogenic index were lower in patients with SCA1 compared to controls (P < 0.001 and P < 0.05, respectively). Our data suggested an impairment in insulin secretion capacity, as well as simultaneous decrease in insulin sensitivity, with an increase in insulin resistance level in patients with SCA1.

BACKGROUND: It has not been clarified yet if persons with multiple sclerosis (MS) are at increased risk to develop glucose metabolism dysregulation. The aims of the present study were to evaluate glucose metabolism characteristics in persons with MS and to compare it to the healthy individuals; to examine the association of glucose metabolism with the level of disability and its progression. METHODS: The study enrolled 78 patients with MS and 26, comparable for age, gender and body mass index (BMI), healthy controls (HC). Disability and its progression were evaluated by the Expanded Disability Status Scale (EDSS) score, progression index (PI) and multiple sclerosis severity score (MSSS). All participants performed an oral glucose tolerance test (OGTT). Insulin and lipid parameters were analyzed. RESULTS: Fasting glucose concentrations (5.3±0.7 in MS patients vs. 4.5±0.9 mmol/L in HC, p=0.001) and 2 hour post-load glucose concentrations were statistically significantly higher in MS patients compared with controls. Glucose levels at all different time points during OGTT, baseline insulin, Homeostasis model assessment of insulin resistance (HOMA-IR), total cholesterol and LDL were statistically significantly (p<0.05) associated with MS, in univariable logistic regression analysis. Glucose level at 120' was independently associated with MS (OR=3.937, 95% CI 1.178-13.159, p=0.026), in the multivariable model. The prevalence of IR was 64.1% in the MS group compared to 30.8% in the control group (p=0.008), based on HOMA-IR. EDSS and Multiple sclerosis severity score (MSSS) were associated with glucose levels at different time points (p<0.05). According to the ROC analysis, best cut-off value for HOMA-IR is 2.3, providing both sensitivity and specificity of 66.7% in discriminating persons with MS and HC. CONCLUSION: Our results demonstrate the presence of higher prevalence of IR in MS patients compared to healthy individuals, and strong association between impaired glucose metabolism and disability. Finally, it has to be emphasized that further studies are warranted to confirm our findings implicating that MS patients have significantly higher risk of impaired glucose metabolism, which could suggest the potential importance of the performance of OGTT in patients with this disorder.
