Erratum to: The gut microbiota profile is associated with insulin action in humans.
The optimal coronary revascularization strategy for patients with diabetes and left main and/or multivessel disease is undetermined. The aim of our study was to evaluate percutaneous coronary intervention (PCI) versus coronary artery bypass graft (CABG) in those patients. We identified 13 articles, published before October 2011, enrolling 6992 patients, whose follow-up period ranged from 1 to 5 years. Patients with PCI had a significant reduction in cerebral vascular attack (CVA) (OR, 0.29; 95 % CI, 0.16-...
Primary objective was to evaluate whether an intensified insulin therapy (IIT) incorporating the target of normal fasting glucose and HbA1c levels could halve the incidence of restenosis/amputation/SCA/death at 6 months after peripheral angioplasty compared with standard care (SC) in patients with type 2 diabetes (DMT2) affected by critical limb ischemia (CLI). Forty-six consecutive patients with DMT2 and CLI were randomly assigned to a parallel, open-label study with IIT (basal-bolus glulisine + glargin...
Clinical frailty and long-term mortality in elderly subjects with diabetes.
Elderly subjects are characterized by a high prevalence of diabetes and clinical frailty. This study aimed to examine the predictive role of clinical frailty on long-term mortality in elderly subjects with and without diabetes. The study evaluated mortality after 12-year follow-up in 188 subjects with diabetes and 1,100 subjects without diabetes selected in 1992. Clinical frailty was assessed according to the "Frailty Staging System" and stratified in tertiles. After 12-year follow-up, mortality was 50.5 %...
We have reported associations of cancer with low triglyceride and high high-density lipoprotein cholesterol (HDL-C) as well as co-presence of low low-density lipoprotein cholesterol (LDL-C) and albuminuria in type 2 diabetes (T2D). This analysis aims to test (1) whether low LDL-C and low triglyceride have synergistic effects to increase cancer risk in T2D and (2) whether high HDL-C enhances the effect of co-presence of low LDL-C and albuminuria on cancer risk. A prospective cohort of patients with T2D, esta...
The gut microbiota profile is associated with insulin action in humans.
The role of the gut microbiota in the induction of metabolic diseases has now been increasingly recognized worldwide. Indeed, a specific gut microbiota has been shown to characterize lean versus obese phenotypes both in humans and mice. We have also recently demonstrated that a precise gut microbiota is associated with the host's responsiveness to a high-fat diet. Therefore, we hypothesized that insulin resistance in humans could also be linked to a specific gut microbiota. To this aim, microbial DNA and RN...
The aim of this study is to evaluate the influence of economic status on clinical care provided to Brazilian youths with type 1 diabetes in daily practice, according to the American Diabetes Association's guidelines. This was a cross-sectional, multicenter study conducted between 2008 and 2010 in 28 public clinics in Brazil. Data were obtained from 1,692 patients (55.3 % female, 56.4 % Caucasian), with a mean age of 13 years (range, 1-18), a mean age at diagnosis of 7.1 ± 4 years and diabetes duratio...
A discovery-phase urine proteomics investigation in type 1 diabetes.
Diabetes is a chronic metabolic disease which can lead to serious health problems particularly in and to the development of cardiovascular and renal complications. The aim of this study is to possibly identify distinctive molecular features in urine samples which might correlate to the progression and complications of type 1 diabetes. Diabetic patients with normo- and micro-albuminuria have been analyzed and compared to a group of control subjects. Urine proteins of control and type 1 diabetes subjects were...
Type 2 diabetes has been associated with an increased prevalence of psychopathology, in comparison with matched non-diabetic controls. However, the cross-sectional design of most studies does not allow causal inferences. The aim of the present study is the exploration of this possible association in patients with type 2 diabetes, in a longitudinal fashion. This prospective observational study was conducted on a consecutive series of 250 type 2 diabetic outpatients and a 1-year follow-up period was performed...
To assess the association between type 2 diabetes and rs10811661 polymorphism, upstream of CDKN2A/B, a literature-based search was conducted to collect data. The pooled OR (odds ratio) and 95 % confidence intervals (CI) were used to assess the strength of association between rs10811661 polymorphism and type 2 diabetes. OR with 95 % CI were performed for allele contrasts, additive genetic model, dominant genetic model and recessive genetic model, respectively. The effect model was used if there was heterog...
The metabolic syndrome (MS) is characterized by chronic inflammation. We aimed to determine the association of white blood cell (WBC) count with prevalence and development of the MS and its components in the general population. A cohort of 1,329 subjects from the local working population aged 41.3 ± 7.5 years and recruited since 2000-2008 was followed up for 4.0 ± 1.2 years. WBC count and MS components were determined at baseline and follow-up. To determine whether WBC predicted incident MS, we used...
Obesity is a significant risk factor for developing diabetes. Pigment epithelium-derived factor (PEDF) has been identified by experimental and clinical studies as both a causative and counter-regulatory factor in the metabolic syndrome. We set out to determine whether serum PEDF levels correlated with the degree of insulin resistance in morbidly obese patients. Sera from 53 patients who were evaluated prior to gastric bypass surgery were analyzed for PEDF levels using a commercial ELISA. None of the patient...
In order to investigate whether short- or long-term glycemic fluctuations could induce oxidative stress and chronic inflammation, we evaluated the relationships between glycemic variability, oxidative stress markers, and high-sensitivity C-reactive protein (hs-CRP). We enrolled 34 patients with type 2 diabetes. As a measure of short-term glycemic variability, mean amplitude of glycemic excursions (MAGE) was computed from continuous glucose monitoring system data. For determining long-term glycemic variabili...
Type 1 diabetes and celiac disease in adults: glycemic control and diabetic complications.
The prevalence of celiac disease (CD) in patients with type 1 diabetes mellitus (T1DM) is 4.5 %. Objective of the study is to investigate (1) the course of glycemic control at CD diagnosis and after the initiation of a gluten-free diet (GFD) in T1DM patients; (2) the prevalence of diabetic complications in T1DM patients with adult onset of CD. In 20 hospitals in the Netherlands, we identified T1DM patients diagnosed with CD at adult age. We retrospectively collected glycated hemoglobin (HbA1c) levels befor...
Influence of heart rate at rest for predicting the metabolic syndrome in older Chinese adults.
The aim of this study was to examine the relationship between seated resting heart rate and the metabolic syndrome (MetS) among older residents of Guangzhou, South China. A total of 30,519 older participants (≥50 years) from the Guangzhou Biobank Cohort Study were stratified into quartiles based on seated resting heart rate. The associations between each quartile and the MetS were assessed using multivariable logistic regression. A total of 6,907 (22.8 %) individuals were diagnosed as having the MetS, w...
A SNP in G6PC2 predicts insulin secretion in type 1 diabetes.
We investigated whether single nucleotide polymorphisms in genes related to glucose metabolism correlate with insulin secretion in type 1 diabetes patients. A cohort of 49 type 1 diabetes patients underwent serial mixed meal tolerance tests to assess insulin secretion. Patients were genotyped for SNPs related to glucose metabolism: CDKAL1 rs7754840, G6PC2 rs560887, HHEX rs1111875, KCNJ11 rs5215. Recently diagnosed patients (
Fasting APO B48 levels are associated with microalbuminuria in patients with type 2 diabetes.
In view of the high incidence of macrovascular diseases in patients with type 2 diabetes mellitus and microalbuminuria, the study evaluates the association of microalbuminuria with fasting plasma Apo B48 levels, a marker of the residual presence of intestinally derived TRLs lipoproteins, thought to be highly atherogenic. We studied 50 patients with type 2 diabetes aged 35-75 years. Exclusion criteria were overt macrovascular disease, overt nephropathy (Glomerular filtration rate (GFR)
Heritability of dietary food intake patterns.
The quality and quantity of food intake affect body weight, but little is known about the genetics of such human dietary intake patterns in relation to the genetics of BMI. We aimed to estimate the heritability of dietary intake patterns and genetic correlation with BMI in participants of the Erasmus Rucphen Family study. The study included 1,690 individuals (42 % men; age range, 19-92), of whom 41.4 % were overweight and 15.9 % were obese. Self-report questionnaires were used to assess the number of day...
Measurement and validation of the nature of salivary adiponectin.
Adiponectin (Ad) is an adipocyte-derived hormone that plays an essential role in regulating insulin sensitivity, inflammation, and atherogenesis. Levels of some hormones in saliva change in a fashion similar to that in plasma in response to a disease or physiological condition. Since saliva is an easy to obtain biological fluid, measurements of salivary hormonal changes are preferred in diagnoses and treatments. Therefore, it was of interest to examine the nature of salivary Ad. While there have been two pu...
1-Hour plasma glucose in obese youth.
Adults with normal glucose tolerance (NGT) but exaggerated plasma glucose excursion at 1 h (1HPG) following the oral glucose tolerance test (OGTT) have significantly higher risk of developing impaired glucose tolerance (IGT) or diabetes. Aim of the study will be to characterize the metabolic phenotype of NGT obese youth according to values of 1HPG. To accomplish this aim, obese patients (N = 1,454; 761 men; 79 IGT; BMI z-score 2.56 ± 0.16 SDS; age 11 ± 0.7 years) from two data sets were analyzed....
Transglutaminase 2 (TG2) is a multifunctional protein with Ca(2+)-dependent transamidating and G protein activity. Previously, we reported that tgm2 -/- mice have an impaired insulin secretion and that naturally occurring TG2 mutations associated with familial, early-onset type 2 diabetes, show a defective transamidating activity. Aim of this study was to get a better insight into the role of TG2 in insulin secretion by identifying substrates of TG2 transamidating activity in the pancreatic beta cell line I...
Autoantibodies to CCL3 are of low sensitivity and specificity for the diagnosis of type 1 diabetes.
Type 1 diabetes (T1D) is a T cell-dependent tissue-specific autoimmune disease, characterized by the selective destruction of the β cells of the pancreatic islets of Langerhans. Recently, contradictory findings have been reported about the relationship of autoantibodies to CC chemokine 3 (CCL3) and T1D, which need to be confirmed by more investigations in larger cohorts. The aim of our research was to investigate whether autoantibodies to CCL3 are useful markers for T1D in a large cohort of Chinese patient...
(31)P-magnetic resonance spectroscopy ((31)P-MRS) is a non-invasive tool to study high-energy phosphate (HEP) metabolism. We evaluate whether (31)P-MRS can detect early changes in kidney HEP metabolism during a 6-month trial with Valsartan. Twenty consecutive stable and normotensive kidney-transplanted patients were enrolled. Nine of them received short-term low-dose Valsartan treatment (80 mg/day) for 6 months, while 11 controls received no medication. Kidney HEP metabolism was evaluated both at baseline...
A replacement for islet equivalents with improved reliability and validity.
Islet equivalent (IE), the standard estimate of isolated islet volume, is an essential measure to determine the amount of transplanted islet tissue in the clinic and is used in research laboratories to normalize results, yet it is based on the false assumption that all islets are spherical. Here, we developed and tested a new easy-to-use method to quantify islet volume with greater accuracy. Isolated rat islets were dissociated into single cells, and the total cell number per islet was determined by using c...
Early intensive therapy in type 2 diabetes can prevent complications. Nevertheless, metabolic control is often sub-optimal in newly diagnosed patients. This web-based survey aimed to evaluate opinions of physicians about treatment, priorities, and barriers in the care of patients first referred to diabetes clinics. Data on physician attitudes toward therapeutic preferences for two clinical case models (same clinical profile, except HbA1c levels of 8.6 and 7.3% at the first access, respectively) were collect...
