RESUMO

BACKGROUND: To analyze data in terms of the glycaemic control and therapeutic regimens used for Type-2 Diabetes Mellitus (T2DM) management in Greece, identify factors that influence clinical decisions and determine the level of compliance of T2DM management with the latest international and local guidelines. METHODS: 'AGREEMENT' was a national-multicenter, non-interventional, cross-sectional disease registry. A total of 1191 adult T2DM patients were enrolled consecutively from 59 sites of the National Health System (NHS) or University Hospitals, representing the majority of Diabetes centers or Diabetes outpatient clinics in Greece with a broad geographic distribution. Patients were stratified by gender and analysis was done according to 3 treatment strategies: A (lifestyle changes or use of one oral antidiabetic agent), B (up to 3 antidiabetic agents including injectables but not insulin) and C (any regimens with insulin). RESULTS: Mean (±SD) HbA1c % of the total population was 7.1 (±1.2) while mean (±SD) FPG (mg/dl) was measured at 136 (±42). The proportion of patients who achieved HbA1c < 7% was 53% and ranged from 74.2% for group A, to 60.6% for group B and 35.5% for group C. Median age of the studied population was 65.0 year old (Interquartile Range-IQR 14.0) with an equal distribution of genders between groups. Patients on insulin therapy (treatment strategy C) were older (median age: 67 years vs 63 or 65 for A and B, respectively) with longer diabetes duration (mean duration: 15.3 years vs 5.2 and 10.1 for A and B, respectively). Patients who received insulin presented poor compliance. There was a consensus for a series of decision criteria and factors that potentially influence clinical decisions, used by physicians for selection of the therapeutic strategy among the three groups. Compliance with international and Greek guidelines received a high score among groups A, B and C. No significant differences were presented as per sites' geographic areas, NHS or University centers and physicians' specialty (endocrinologists, diabetologists and internists). CONCLUSIONS: The presented findings suggest the need for improvement of the glycaemic control rate, especially among insulin treated patients as this group seems to achieve low glycaemic control, by setting appropriate HbA1c targets along with timely and individualised intensification of treatment as well as post-therapy evaluation of the compliance with the proposed treatment.

RESUMO

BACKGROUND: Diabetic nephropathy (DN) is one of the major late complications of diabetes. Treatment aimed at slowing down the progression of DN is available but methods for early and definitive detection of DN progression are currently lacking. The 'Proteomic prediction and Renin angiotensin aldosterone system Inhibition prevention Of early diabetic nephRopathy In TYpe 2 diabetic patients with normoalbuminuria trial' (PRIORITY) aims to evaluate the early detection of DN in patients with type 2 diabetes (T2D) using a urinary proteome-based classifier (CKD273). METHODS: In this ancillary study of the recently initiated PRIORITY trial we aimed to validate for the first time the CKD273 classifier in a multicentre (9 different institutions providing samples from 165 T2D patients) prospective setting. In addition we also investigated the influence of sample containers, age and gender on the CKD273 classifier. RESULTS: We observed a high consistency of the CKD273 classification scores across the different centres with areas under the curves ranging from 0.95 to 1.00. The classifier was independent of age (range tested 16-89 years) and gender. Furthermore, the use of different urine storage containers did not affect the classification scores. Analysis of the distribution of the individual peptides of the classifier over the nine different centres showed that fragments of blood-derived and extracellular matrix proteins were the most consistently found. CONCLUSION: We provide for the first time validation of this urinary proteome-based classifier in a multicentre prospective setting and show the suitability of the CKD273 classifier to be used in the PRIORITY trial.

RESUMO

The mechanisms leading to the development of heart failure (HF) in diabetes mellitus (DM) patients are multifactorial. Assessing the risk of HF development in patients with DM is valuable not only for the identification of a high-risk subgroup, but also equally important for defining low-risk subpopulations. Nowadays, DM and HF have been recognized as sharing similar metabolic pathways. Moreover, the clinical manifestation of HF can be independent of LVEF classification. Consequently, approaching HF should be through structural, hemodynamic and functional evaluation. Thus, both imaging parameters and biomarkers are important tools for the recognition of diabetic patients at risk of HF manifestation and HF phenotypes, and arrhythmogenic risk, and eventually for prognosis, aiming to improve patients' outcomes utilizing drugs and non-pharmaceutical cardioprotective tools such as diet modification.

RESUMO

AIMS: Baseline diabetic retinopathy (DR) and risk of development of microalbuminuria, kidney function decline, and cardiovascular events (CVEs) in type 2 diabetes. METHODS: Post-hoc analysis of the PRIORITY study including 1758 persons with type 2 diabetes and normoalbuminuria followed for a median of 2.5 (IQR: 2.0-3.0) years. DR diagnosis included non-proliferative and proliferative abnormalities, macular oedema, or prior laser treatment. Cox models were fitted to investigate baseline DR presence with development of persistent microalbuminuria (urinary albumin-creatinine ratio > 30 mg/g); chronic kidney disease (CKD) G3 (eGFR <60 ml/min/1.73m2); and CVE. Models were adjusted for relevant risk factors. RESULTS: At baseline, 304 (17.3 %) had DR. Compared to persons without DR, they were older (mean ± SD: 62.7 ± 7.7 vs 61.4 ± 8.3 years, p = 0.019), had longer diabetes duration (17.9 ± 8.4 vs. 10.6 ± 7.0 years, p < 0.001), and higher HbA1c (62 ± 13 vs. 56 ± 12 mmol/mol, p < 0.001). The adjusted hazard ratios of DR at baseline for development of microalbuminuria (n = 197), CKD (n = 166), and CVE (n = 64) were: 1.50 (95%CI: 1.07, 2.11), 0.87 (95%CI: 0.56, 1.34), and 2.61 (95%CI: 1.44, 4.72), compared to without DR. CONCLUSIONS: Presence of DR in normoalbuminuric type 2 diabetes was associated with an increased risk of developing microalbuminuria and CVE, but not with kidney function decline.

RESUMO

Despite high-quality evidence highlighting metabolic surgery as an effective treatment option for type 2 diabetes mellitus (T2DM), the number of patients receiving bariatric surgery (BS) remains low. Since the introduction of the Diabetes Surgery Summit II (DSS-II) eligibility criteria, data on eligibility rates for BS in T2DM cohorts remain scarce. The aims of the present study were to examine in a real-world clinical setting: (i) what is the percentage of T2DM patients visiting diabetes outpatient clinics who meet the DSS-II eligibility criteria, (ii) how many of these have been informed about the option of BS, and (iii) what are the characteristics associated with eligibility and awareness of BS. Demographic, anthropometric, clinical and socioeconomic data were obtained for all patients with T2DM who were consecutively examined in the outpatient clinics of three large-volume university hospitals (n = 1167). A medical registry form was completed to screen for BS eligibility. Patients were considered eligible if the recommendation by DSS-II criteria was either to "consider" or "recommend" BS. Eligible patients were further inquired whether they had ever been informed about the option of BS by their physicians. The advanced DiaRem score (ADRS) was applied to eligible patients to assess their probability of achieving postoperative T2DM remission. A significant percentage of T2DM patients who are routinely assessed in outpatient clinics meet the DSS-II eligibility criteria (15.3%). Eligible patients are younger and more obese, have a shorter T2DM duration, worse glycaemic control and better renal function, compared to non-eligible ones. Among eligible patients, only 39.3% have been medically informed about the option of BS. Informed patients are younger and more severely obese than non-informed ones. A significant percentage of non-informed patients (35%) have an ADRS ≤10, indicating a considerable probability for T2DM remission after BS, and are thus deprived of this opportunity due to lack of appropriate medical counseling. Screening and awareness of BS remain an unmet need in current T2DM management. Future research should focus on intensifying screening for BS eligibility at every medical visit and promoting evidence-based clinical recommendations for patients expected to benefit the most.

RESUMO

BACKGROUND: Microalbuminuria is an early sign of kidney disease in people with diabetes and indicates increased risk of cardiovascular disease. We tested whether a urinary proteomic risk classifier (CKD273) score was associated with development of microalbuminuria and whether progression to microalbuminuria could be prevented with the mineralocorticoid receptor antagonist spironolactone. METHODS: In this multicentre, prospective, observational study with embedded randomised controlled trial (PRIORITY), we recruited people with type 2 diabetes, normal urinary albumin excretion, and preserved renal function from 15 specialist centres in ten European countries. All participants (observational cohort) were tested with the CKD273 classifier and classified as high risk (CKD273 classifier score >0·154) or low risk (≤0·154). Participants who were classified as high risk were entered into a randomised controlled trial and randomly assigned (1:1), by use of an interactive web-response system, to receive spironolactone 25 mg once daily or matched placebo (trial cohort). The primary endpoint was development of confirmed microalbuminuria in all individuals with available data (observational cohort). Secondary endpoints included reduction in incidence of microalbuminuria with spironolactone (trial cohort, intention-to-treat population) and association between CKD273 risk score and measures of impaired renal function based on estimated glomerular filtration rate (eGFR; observational cohort). Adverse events (particularly gynaecomastia and hyperkalaemia) and serious adverse events were recorded for the intention-to-treat population (trial cohort). This study is registered with the EU Clinical Trials Register (EudraCT 20120-004523-4) and ClinicalTrials.gov (NCT02040441) and is completed. FINDINGS: Between March 25, 2014, and Sept 30, 2018, we enrolled and followed-up 1775 participants (observational cohort), 1559 (88%) of 1775 participants had a low-risk urinary proteomic pattern and 216 (12%) had a high-risk pattern, of whom 209 were included in the trial cohort and assigned to spironolactone (n=102) or placebo (n=107). The overall median follow-up time was 2·51 years (IQR 2·0-3·0). Progression to microalbuminuria was seen in 61 (28%) of 216 high-risk participants and 139 (9%) of 1559 low-risk participants (hazard ratio [HR] 2·48, 95% CI 1·80-3·42; p<0·0001, after adjustment for baseline variables of age, sex, HbA1c, systolic blood pressure, retinopathy, urine albumin-to-creatinine ratio [UACR], and eGFR). Development of impaired renal function (eGFR <60 mL/min per 1·73 m2) was seen in 48 (26%) of 184 high-risk participants and 119 (8%) of 1423 low-risk participants (HR 3·50; 95% CI 2·50-4·90, after adjustment for baseline variables). A 30% decrease in eGFR from baseline (post-hoc endpoint) was seen in 42 (19%) of 216 high-risk participants and 62 (4%) of 1559 low-risk participants (HR 5·15, 95% CI 3·41-7·76; p<0·0001, after adjustment for basline eGFR and UACR). In the intention-to-treat trial cohort, development of microalbuminuria was seen in 35 (33%) of 107 in the placebo group and 26 (25%) of 102 in the spironolactone group (HR 0·81, 95% CI 0·49-1·34; p=0·41). In the safety analysis (intention-to-treat trial cohort), events of plasma potassium concentrations of more than 5·5 mmol/L were seen in 13 (13%) of 102 participants in the spironolactone group and four (4%) of 107 participants in the placebo group, and gynaecomastia was seen in three (3%) participants in the spironolactone group and none in the placebo group. One patient died in the placebo group due to a cardiac event (considered possibly related to study drug) and one patient died in the spironolactone group due to cancer, deemed unrelated to study drug. INTERPRETATION: In people with type 2 diabetes and normoalbuminuria, a high-risk score from the urinary proteomic classifier CKD273 was associated with an increased risk of progression to microalbuminuria over a median of 2·5 years, independent of clinical characteristics. However, spironolactone did not prevent progression to microalbuminuria in high-risk patients. FUNDING: European Union Seventh Framework Programme.

RESUMO

BACKGROUND: Idiopathic non-cirrhotic portal hypertension (INCPH) is mainly associated with thrombophilia in Western countries. Paroxysmal nocturnal hemoglobinuria (PNH) is a rare hematologic disease that manifests with hemolytic anemia, thrombosis, and peripheral blood cytopenias. Portal and hepatic venous thrombosis were reported in PNH. A rare case of INCPH complicating PNH is described. CASE SUMMARY: A 63-year old woman with a 2-year past medical history of PNH without treatment was admitted because of jaundice and refractory ascites requiring large volume paracentesis. Liver histology revealed portal venopathy with portal fibrosis and sclerosis, nodular regenerative hyperplasia, parenchymal ischemic changes, and focal sinusoidal and perivenular fibrosis without bridging fibrosis or cirrhosis, all indicative of INCPH. The flow cytometry confirmed PNH diagnosis and eculizumab treatment was initiated. Her condition was improved gradually, bilirubin was normalized 6 months following initiation of eculizumab, and 1 year later diuretics were stopped. CONCLUSION: Eculizumab improved intravascular hemolysis and reversed clinical manifestations of INCPH in a patient with paroxysmal nocturnal hemoglobinuria.

RESUMO

BACKGROUND: Newer antidiabetic drugs, i.e., dipeptidyl peptidase-4 (DPP-4) inhibitors, sodium-glucose cotransporter-2 (SGLT-2) inhibitors, and glucagon-like peptide-1 receptor agonists (GLP-1 RAs) may exert distinct cardiovascular effects. We sought to explore their impact on vascular function. METHODS: Published literature was systematically searched up to January 2018 for clinical studies assessing the effects of DPP-4 inhibitors, GLP-1 RAs, and SGLT-2 inhibitors on endothelial function and arterial stiffness, assessed by flow-mediated dilation (FMD) of the brachial artery and pulse wave velocity (PWV), respectively. For each eligible study, we used the mean difference (MD) with 95% confidence intervals (CIs) for FMD and PWV. The pooled MD for FMD and PWV were calculated by using a random-effect model. The presence of heterogeneity among studies was evaluated by the I 2 statistic. RESULTS: A total of 26 eligible studies (n = 668 patients) were included in the present meta-analysis. Among newer antidiabetic drugs, only SGLT-2 inhibitors significantly improved FMD (pooled MD 1.14%, 95% CI: 0.18 to 1.73, p = 0.016), but not DPP-4 inhibitors (pooled MD = 0.86%, 95% CI: -0.15 to 1.86, p = 0.095) or GLP-1 RA (pooled MD = 2.37%, 95% CI: -0.51 to 5.25, p = 0.107). Both GLP-1 RA (pooled MD = -1.97, 95% CI: -2.65 to -1.30, p < 0.001) and, to a lesser extent, DPP-4 inhibitors (pooled MD = -0.18, 95% CI: -0.30 to -0.07, p = 0.002) significantly decreased PWV. CONCLUSIONS: Newer antidiabetic drugs differentially affect endothelial function and arterial stiffness, as assessed by FMD and PWV, respectively. These findings could explain the distinct effects of these drugs on cardiovascular risk of patients with type 2 diabetes.

RESUMO

INTRODUCTION: The aim of this study was to determine the prevalence of thyroid dysfunction in Greek patients with type 1 (T1DM) and type 2 (T2DM) diabetes mellitus as well as its possible relations to glycaemic control and to diabetic complications. METHODS: A total of 1015 patients, consecutively followed in the Outpatient Diabetes Center, were studied. Anthropometric and biochemical measurements, occurrence of diabetes complications, and classical comorbidities were assessed. Average HbA1c of the previous year was calculated. Wellbeing was determined, using a 10-point optimal scale. All the above parameters were compared between subjects with or without thyroid disease. RESULTS: All patients were euthyroid at the time of the study, either on thyroid medications or not. Hypothyroidism occurrence did not differ between T2DM and T1DM patients (37.1% versus 43.5%, p > 0.05). Nodular goiter was observed more frequently in T2DM patients (34.1% versus 18.8%, p < 0.05). T2DM patients with hypothyroidism compared to those without hypothyroidism had higher HbA1c (7.27% versus 6.98%, p < 0.01), TChol (184.97 mg/dl versus 168.17 mg/dl, p < 0.001), and higher HDL-Chol (51.28 mg/dl versus 46.77 mg/dl, p < 0.01). T2DM patients without hypothyroidism had a better wellness feeling (7.5 versus 5.3 points, p < 0.01). CONCLUSIONS: Screening for thyroid disease among T2DM patients should be routinely considered, as it is found to be an additional commorbidity. If it remains undiagnosed, it could aggravate the clinical course of the disease.

RESUMO

INTRODUCTION: Diabetes mellitus affects 9% of the European population and accounts for 15% of healthcare expenditure, in particular, due to excess costs related to complications. Clinical trials aiming for earlier prevention of diabetic nephropathy by renin angiotensin system blocking treatment in normoalbumuric patients have given mixed results. This might reflect that the large fraction of normoalbuminuric patients are not at risk of progression, thereby reducing power in previous studies. A specific risk classifier based on urinary proteomics (chronic kidney disease (CKD)273) has been shown to identify normoalbuminuric diabetic patients who later progressed to overt kidney disease, and may hold the potential for selection of high-risk patients for early intervention. Combining the ability of CKD273 to identify patients at highest risk of progression with prescription of preventive aldosterone blockade only to this high-risk population will increase power. We aim to confirm performance of CKD273 in a prospective multicentre clinical trial and test the ability of spironolactone to delay progression of early diabetic nephropathy. METHODS AND ANALYSIS: Investigator-initiated, prospective multicentre clinical trial, with randomised double-masked placebo-controlled intervention and a prospective observational study. We aim to include 3280 type 2 diabetic participants with normoalbuminuria. The CKD273 classifier will be assessed in all participants. Participants with high-risk pattern are randomised to treatment with spironolactone 25 mg once daily, or placebo, whereas, those with low-risk pattern will be observed without intervention other than standard of care. Treatment or observational period is 3 years.The primary endpoint is development of confirmed microalbuminuria in 2 of 3 first morning voids urine samples. ETHICS AND DISSEMINATION: The study will be conducted under International Conference on Harmonisation - Good clinical practice (ICH-GCP) requirements, ethical principles of Declaration of Helsinki and national laws. This first new biomarker-directed intervention trial aiming at primary prevention of diabetic nephropathy may pave the way for personalised medicine approaches in treatment of diabetes complications.

RESUMO

In type 2 diabetes, the threonine (Thr) for alanine (Ala) codon 54 polymorphism of the fatty acid binding protein 2 gene is associated with elevated fasting and postprandial triglycerides and dyslipidemia when compared with the wild type (Ala-54/Ala-54). To assess whether this is the case in patients with type 1 diabetes, who usually do not manifest the metabolic syndrome, we screened 181 patients with similar glycemic control as the type 2 patients. Thirty percent were heterozygous, and 9% were homozygous for the polymorphism. Mean (+/-SEM) fasting plasma triglyceride levels in patients with the wild type (n = 84), those heterozygous for Ala-54/Thr-54 (n = 44), and those homozygous for the Thr-54 (n = 13) were 1.0 +/- 0.07, 1.1 +/- 0.17, and 1.2 +/- 0.23 mmol/liter, respectively. In addition, there were no differences in total, low-density lipoprotein, high-density lipoprotein, and non-high density lipoprotein cholesterol among the three groups. After a fat load, the postprandial area under the curve of triglyceride in plasma, chylomicrons, and very low-density lipoprotein were similar between the wild type (n = 18) and the Thr-54 homozygotes (n = 12). In conclusion, in contrast to type 2, type 1 diabetes does not interact with the codon 54 polymorphism of the fatty acid binding protein 2 gene to cause hypertriglyceridemia/dyslipidemia. Insulin resistance could account possibly for this difference.

RESUMO

BACKGROUND: Statin treatment improves survival in patients with atherosclerosis, but their effect on the glucose-induced variations of inflammatory markers, is unknown. We examined the effect of combined therapy with atorvastatin and metformin on glucose-induced variations of inflammatory molecules in patients with newly diagnosed diabetes mellitus type 2 (DM). METHODS: Thirty five subjects with newly diagnosed DM were randomized to receive metformin 850 mg/d (M, n=17) or metformin 850 mg/d+atorvastatin 10mg (n=18). All subjects underwent glucose loading (75 g oral glucose) at baseline and after 12 weeks of treatment. Blood samples were obtained at baseline and 3h post-loading, while serum tumor necrosis factor alpha (TNF-α) levels were determined at baseline and at 3h. RESULTS: Serum TNF-α remained unchanged in metformin at baseline (1.36±0.18 to 1.47±0.21 pg/ml p=NS) and after treatment (1.44±0.71 to 1.31±0.17 pg/ml, p=NS), while it was reduced in metformin+atorvastatin (2.3±0.3 to 2.0±0.4 pg/ml, p=NS at baseline and 1.80±0.2 to 1.65±0.2 pg/ml, p=0.03 after treatment). CONCLUSIONS: Interestingly, the combination of metformin and atorvastatin partly prevents the glucose-loading induced elevation of glucose levels (at 1 h), suggesting a better response to glucose intake than monotherapy with metformin. In addition, combined treatment with atorvastatin and metformin reduces the post-glucose loading levels of TNF-α compared to metformin monotherapy.

RESUMO

BACKGROUND: Statin treatment has been reported to improve survival in patients with atherosclerosis, partly by improving vascular endothelial function. Elevation of blood glucose concentrations impairs endothelial function and promotes atherogenesis, but the effect of statins on glucose-induced endothelial dysfunction is unknown. Endothelium-dependent dilation (EDD) measured by gauge-strain plethysmography in the forearm is considered to be a reliable marker of endothelial function in forearm resistance vessels. OBJECTIVE: This study examined the combined effects of metformin and atorvastatin treatment on glucose-induced endothelial dysfunction (as EDD) in patients with newly diagnosed type 2 diabetes mellitus (DM). METHODS: Patients with newly diagnosed DM were recruited and were randomly assigned to receive metformin 850 mg/d or metformin 850 mg/d + atorvastatin 10 mg/d for 6 weeks in a single-blind study. All patients underwent glucose loading (75 g oral glucose after 12 hours of fasting) at baseline and at the end of the treatment period. Blood samples were obtained at baseline before glucose loading and 3 hours after loading to determine serum concentrations of cholesterol, lipoproteins, triglycerides, glucose, and glycosylated hemoglobin. EDD was evaluated at baseline and at 1, 2, and 3 hours after loading. The investigators were blinded to the treatment group assignments, and all analyses were performed in a blinded manner. Adverse events (eg, gastrointestinal disorders, myopathy, liver disorders) were monitored based on reported symptoms or signs (eg, myalgias, muscle cramps), clinical examination, and laboratory parameters (eg, increased liver and muscle enzymes). RESULTS: Thirty-two white patients with newly diagnosed type 2 DM were randomly assigned to receive metformin 850 mg/d (n = 17 [12 men]; mean [SD] age, 53.88 [45] years; body mass index [BMI], 28.7 [4.5] kg/m²) or metformin 850 mg/d + atorvastatin 10 mg/d (n = 15 [6 men]; mean age, 52.53 [37] years; BMI, 28.5 [2.1] kg/m²). At baseline, EDD was reduced 1 and 2 hours after glucose loading in both study groups (P < 0.01). Glucose loading was associated with an elevation of blood glucose concentrations at 1 and 2 hours (P < 0.01 vs resting levels before loading), and concentrations returned to resting levels at 3 hours, in both groups at baseline and after treatment. Metformin alone or in combination with atorvastatin was associated with a significant reduction in resting glucose concentrations after 6 weeks (both, P < 0.05 vs baseline), but only the combination of metformin + atorvastatin partly prevented the glucose-induced elevation of serum glucose at 1 hour after loading and the glucose-induced decrease in EDD (both, P < 0.01 vs baseline). CONCLUSIONS: Glucose loading blunted endothelial function, with a deterioration in EDD, in these patients with newly diagnosed type 2 DM. However, combined treatment with metformin and atorvastatin for 6 weeks partly prevented the glucose-induced impairment of EDD in these patients, with a significant difference compared with monotherapy with metformin.
