The very low-calorie ketogenic diet (VLCKD) represents an opportunity to attain clinically relevant weight loss in obese patients. Functional hypogonadism represents a frequent hormonal disorder associated with obesity and visceral fat accumulation characterized by low testosterone levels and subnormal LH levels.To evaluate the early effects of VLCKD on serum total testosterone (TT) levels in non-diabetic obese patients.Twenty-two obese male patients (mean age 39.3 ± 11.7 years, mean BMI 38.2 ± 6.4 kg/mAfter 7 and 28 days on a VLCKD, a significant and persistent reduction in body weight, BMI, fat mass, blood glucose, insulin, and HOMA index was observed compared with baseline. TT significantly increased after 7 days (+35 ± 64 ng/dl) and 28 days (+74 ± 97 ng/dl) on a VLCKD. In addition to TT, a significant increase in serum sex hormone-binding globulin (SHBG) levels was observed after 7 (+2.1 ± 4.1) and 28 days (+7.7 ± 10.0). However, both calculated free testosterone and LH did not change after 7 or 28 days of VLCKD. Following cessation of VLCKD, hypogonadal subjects achieved a higher percentage of total weight loss (8.5 ± 1.5%), a greater reduction in weight (-9.94 ± 1.66 kg), fat mass (-7 ± 2.1 kg), and waist circumference (-6.31 ± 2.65 cm), and a greater improvement in glycaemia (-8.75 ± 10.92 mg/dl) as compared with eugonadal subjects. Furthermore, hypogonadal subjects exhibited a trend of higher TT increase (+98.12 ± 71.51 ng/dl) as compared with eugonadal subjects.VLCKD results in rapid improvements in TT levels associated with weight loss in male obese non-diabetic subjects, particularly in the presence of obesity-related hypogonadism.

To report prespecified and post hoc analyses of the SoliMix dataset exploring the impact of baseline participant characteristics on the original SoliMix study outcomes, to enable informed treatment choices for people with different biomedical characteristics.SoliMix (EudraCT 2017-003370-13) compared once-daily iGlarLixi (a fixed-ratio combination of insulin glargine 100 U/mL and the glucagon-like peptide-1 receptor agonist lixisenatide) with twice-daily BIAsp 30 (30% insulin aspart and 70% insulin aspart protamine). In this analysis, the original primary outcomes of noninferiority of iGlarLixi versus BIAsp 30 in terms of glycated haemoglobin (HbA1c) change and superiority in terms of body weight change, together with change in basal insulin dose and hypoglycaemia outcomes, were investigated by baseline age, duration of diabetes, insulin dose, HbA1c level, body mass index (BMI), and renal function.No evidence of difference in comparative treatment effect was detected across baseline age, duration of diabetes, insulin dose, HbA1c level, BMI and renal function subgroups for any endpoint (all heterogeneity P 0.05), except American Diabetes Association Level 2 hypoglycaemia event rate when stratified by insulin dose (P = 0.011), which may be a chance difference given multiple testing and the small numbers of Level 2 events.Treatment effects of iGlarLixi were consistent irrespective of baseline HbA1c, insulin dose, BMI, age, duration of diabetes and renal function, supporting the use of iGlarLixi as an efficacious and well-tolerated treatment option in people with type 2 diabetes with a wide range of biomedical characteristics.

To explore details of the incidence and rates of daytime and nocturnal hypoglycaemia, levels of hypoglycaemia, and relationship to glycated haemoglobin (HbA1c), when comparing iGlarLixi versus premixed biphasic insulin aspart 30 (BIAsp 30) in the SoliMix randomized controlled trial.This exploratory analysis of SoliMix used logistic regression and negative binomial regression analyses to assess between-treatment differences in the incidence and rates of hypoglycaemia by time of day. A negative binomial model was used to derive estimated annualized hypoglycaemia rates as a function of HbA1c.iGlarLixi was associated with lower incidence and rates of American Diabetes Association Level 2 (54 mg/dL [3.0 mmol/L]) hypoglycaemia during both night and day versus BIAsp 30. Incidence and rates of Level 1 (70 to ≥54 mg/dL [3.9 to ≥3.0 mmol/L]) hypoglycaemia were also mostly shown to be reduced with iGlarLixi versus BIAsp 30. Severe (Level 3) events were too few for analysis (n = 3). iGlarLixi was associated with lower modelled event rates of Level 2 and Level 1 hypoglycaemia over a wide range of HbA1c levels versus BIAsp 30.These results show that the lower HbA1c levels and weight benefit seen with iGlarLixi versus premixed BIAsp 30 in people with type 2 diabetes advancing their basal insulin therapy in the SoliMix trial are also accompanied by a lower risk of hypoglycaemia at any time of day and across a broad range of HbA1c levels.

We evaluated the role of the p66Shc redox adaptor protein in pancreatic β-cell insulin resistance that develops under lipotoxic conditions and with excess body fat. Prolonged exposure to palmitate in vitro or the presence of overweight/obesity augmented p66Shc expression levels and caused an impaired ability of exogenous insulin to increase cellular insulin content and secreted C-peptide levels in INS-1E cells and human and murine islets. In INS-1E cells, p66Shc knockdown resulted in enhanced insulin-induced augmentation of insulin content and C-peptide secretion and prevented the ability of palmitate to impair these effects of insulin. Conversely, p66Shc overexpression impaired insulin-induced augmentation of insulin content and C-peptide secretion in both the absence and presence of palmitate. Under lipotoxic condition, the effects of p66Shc are mediated by a p53-induced increase in p66Shc protein levels and JNK-induced p66Shc phosphorylation at Ser36 and appear to involve the phosphorylation of the ribosomal protein S6 kinase at Thr389 and of insulin receptor substrate 1 at Ser307, resulting in the inhibition of insulin-stimulated protein kinase B phosphorylation at Ser473. Thus, the p66Shc protein mediates the impaired β-cell function and insulin resistance induced by saturated fatty acids and excess body fat.

Current views show that an impaired balance partly explains the fat accumulation leading to obesity. Fetal malnutrition and early exposure to endocrine-disrupting compounds also contribute to obesity and impaired insulin secretion and/or sensitivity. The liver plays a major role in systemic glucose homeostasis through hepatokines secreted by hepatocytes. Hepatokines influence metabolism through autocrine, paracrine, and endocrine signaling and mediate the crosstalk between the liver, non-hepatic target tissues, and the brain. The liver also synthetizes bile acids (BAs) from cholesterol and secretes them into the bile. After food consumption, BAs mediate the digestion and absorption of fat-soluble vitamins and lipids in the duodenum. In recent studies, BAs act not simply as fat emulsifiers but represent endocrine molecules regulating key metabolic pathways. The liver is also the main site of the production of ketone bodies (KBs). In prolonged fasting, the brain utilizes KBs as an alternative to CHO. In the last few years, the ketogenic diet (KD) became a promising dietary intervention. Studies on subjects undergoing KD show that KBs are important mediators of inflammation and oxidative stress. The present review will focus on the role played by hepatokines, BAs, and KBs in obesity, and diabetes prevention and management and analyze the positive effects of BAs, KD, and hepatokine receptor analogs, which might justify their use as new therapeutic approaches for metabolic and aging-related diseases.

SommarioL’irisina è una miochina secreta dal muscolo scheletrico in seguito ad attività fisica, in grado di regolare l’omeostasi glucidica ed energetica, agendo su numerosi tessuti e intervenendo su diversi pathways metabolici. Un’alterazione dei livelli sierici di irisina potrebbe promuovere l’insorgenza di patologie metaboliche, tra cui il diabete mellito di tipo 2. Numerosi studi su modelli animali di diabete e/o obesità hanno dimostrato che la somministrazione di irisina esogena è in grado di esercitare effetti antidiabetici e antiobesità.

Obesity with its associated complications represents a social, economic and health problem of utmost importance worldwide. Specifically, obese patients carry a significantly higher risk of developing cardiovascular disease compared to nonobese individuals. Multiple molecular mechanisms contribute to the impaired biological activity of the distinct adipose tissue depots in obesity, including secretion of proinflammatory mediators and reactive oxygen species, ultimately leading to an unfavorable impact on the cardiovascular system. This review summarizes data relating to the contribution of the main adipose tissue depots, including both remote (i.e., intra-abdominal, hepatic, skeletal, pancreatic, renal, and mesenteric adipose fat), and cardiac (i.e., the epicardial fat) adipose locations, on the cardiovascular system. Finally, we discuss both pharmacological and non-pharmacological strategies aimed at reducing cardiovascular risk through acting on adipose tissues, with particular attention to the epicardial fat.

Background GLP-1 receptor agonists (GLP-1 RA) and SGLT-2 inhibitors (SGLT-2i) have shown to reduce the risk of major adverse cardiovascular events (MACE), death and worsening nephropathy when added to standard of care. However, these two dug classes differ in efficacy and safety. We compared the effectiveness and safety profile of GLP-1 RA and SGLT-2i in a large and unselected cohort of patients with type 2 diabetes resident in Lombardy from 2015 to 2020. Methods Using linkable administrative health databases, we included patients aged 50 years and older initiating GLP-1 RA or SGLT-2i. Clinical events were: death, hospital admission for myocardial infarction (MI), stroke, heart failure (HF), and renal disease as individual and composite outcomes (MACE-3: all cause-death, non-fatal MI, non-fatal stroke; MACE-4: MACE-3 plus unstable angina). Outcomes were evaluated separately in subjects with and without previous cardiovascular (CV) diseases. Treatments were compared using Cox proportional hazards regression model after Propensity Score Matching (PSM) in both intention-to-treat (ITT) and per protocol (PP) analyses. Serious adverse events were also evaluated. Results The analysis comprised 20,762 patients per cohort. The ITT analysis showed a significant risk reduction for non-fatal MI (HR 0.77; CI 95% 0.66–0.90), MACE-3 (HR 0.91; CI 95% 0.84–0.98), and MACE-4 (HR 0.92; CI 95% 0.86–0.99) in GLP-1RA compared with SGLT-2i users, while no difference was reported in the incidence of HF hospitalization and stroke between the two cohorts. Similar benefits were found in the subgroup of patients without previous CV diseases only. PP analysis largely confirmed the main results. The incidence of serious adverse events was low in both cohorts ( Conclusions GLP-1RA showed to be equally safe and more effective than SGLT-2i in reducing the risk of MACE-3, MACE-4 and MI. This study adds to the growing body of real-world evidence addressing the specific clinical properties of GLP-1RA and SGLT-2i in everyday practice to tailor treatment to the individual patient.

The primary objective of the TROPHIES observational study is to estimate the duration of treatment on dulaglutide or liraglutide without a significant treatment change by 24 months in patients with type 2 diabetes (T2D) initiating their first injectable treatment with these glucagon-like peptide-1 receptor agonists (GLP-1 RAs). This manuscript presents 12-month interim data.TROPHIES is a prospective, non-comparative, observational study of patients with T2D in Europe, naïve to injectable antihyperglycaemic treatments and initiating dulaglutide or liraglutide. Data on clinical characteristics, GLP-1 RA persistence and treatment patterns of glucose-lowering medication were collected at initiation of first injectable therapy and by 12 months.By 12 months, 1014 dulaglutide and 991 liraglutide patients were eligible across France, Germany and Italy. Both cohorts presented a high probability [95% confidence interval (CI)] of GLP-1 RA persistence [dulaglutide, 0.88 (0.86 to 0.90); liraglutide, 0.83 (0.80 to 0.85)] and reduction in mean glycated haemoglobin percentage (95% CI) from baseline [dulaglutide, -1.18 (-1.27 to -1.08); liraglutide, -1.15 (-1.26 to -1.05)] with 48.2% of dulaglutide and 41.2% of liraglutide patients reaching their individualized glycated haemoglobin percentage target set by the physician at baseline. Mean weight (95% CI) change from baseline was -3.2 kg (-3.6 to -2.8) for dulaglutide and -3.4 kg (-3.9 to -3.0) for liraglutide. Slight changes in concomitant medications were observed compared with baseline.In the real-world setting, dulaglutide and liraglutide cohorts achieved good persistence with similarly improved glycaemic control that was accompanied by weight loss at 12 months, consistent with previous clinical trial results.

Type 1 diabetes (T1D) and type 2 diabetes (T2D) are two distinct diseases, with different etiology and pathogenesis, but with a common outcome (hyperglycemia), caused by almost complete or reduced loss of β-cell functional mass, respectively. Although the causes that lead to β-cell failure are different (typically immune-mediated for T1D, while related to metabolic stress for T2D), the underlying molecular pathways are almost sim¬ilar in both forms of diabetes. In this review we try to highlight common molecular mechanisms of β-cells damage in T1D and T2D, which could suggest new promising common therapeutic targets.

To assess patient-reported outcomes (PROs) in the SoliMix trial, which compared the efficacy and safety of iGlarLixi versus BIAsp 30 in people with type 2 diabetes (T2D).SoliMix (EudraCT: 2017-003370-13), a 26-week, open-label study, randomized (1:1) 887 adults with T2D and HbA1c ≥7.5%-≤10.0% (≥58-≤86 mmol/mol) on basal insulin plus oral antihyperglycaemic drugs (OADs) to once-daily iGlarLixi or twice-daily premix insulin, BIAsp 30. PROs were assessed using the Treatment-Related Impact Measure Diabetes (TRIM-D) and Global Treatment Effectiveness Evaluation (GTEE) questionnaires.Over 26 weeks, iGlarLixi showed greater improvement from baseline versus BIAsp 30 in total TRIM-D score (least squares mean difference [95% confidence interval]: 5.08 [3.69, 6.47]; effect size: 0.32) and in each TRIM-D domain, with the greatest differences seen in diabetes management (8.47 [6.11, 10.84]) and treatment burden (6.95 [4.83, 9.07]). GTEE scores showed a greater proportion of participants and physicians rated a complete or marked improvement of diabetes control with iGlarLixi (80.5%, 82.8%) versus BIAsp 30 (63.3%, 65.1%) at week 26. Post hoc analyses showed that after adjusting for HbA1c, body weight and hypoglycaemia outcomes, iGlarLixi continued to show greater improvements in TRIM-D total scores versus BIAsp 30.In addition to better glycaemic control, weight benefit and less hypoglycaemia, once-daily iGlarLixi provided improved diabetes management, treatment burden and perceived effectiveness versus twice-daily premix BIAsp 30, further supporting iGlarLixi as an advanced treatment option in people with suboptimally controlled T2D on basal insulin plus OADs.

Introduction The TROPHIES observational study enrolled patients with type 2 diabetes mellitus (T2DM) initiating their first injectable treatment with the glucagon-like peptide 1 receptor agonists (GLP-1 RAs) dulaglutide or liraglutide. This manuscript focuses on the study design, baseline characteristics of the enrolled population, and factors associated with GLP-1 RA choice. Methods TROPHIES is a prospective, observational, 24-month study conducted in France, Germany, and Italy. Inclusion criteria include adult patients with T2DM, naïve to injectable antihyperglycemic treatments, initiating dulaglutide or liraglutide per routine clinical practice. The primary outcome is the duration of treatment on dulaglutide or liraglutide without a significant treatment change. Results The analysis included 2181 patients (dulaglutide, 1130; liraglutide, 1051) (cutoff date May 15, 2019). The population was 56% male with mean [standard deviation (SD)] patient characteristics at baseline as follows: age, 59.2 (11.0) years; body mass index (BMI), 33.9 (6.6) kg/m2; T2DM duration, 8.5 (6.9) years; and glycated hemoglobin (HbA1c), 8.2 (1.3)%. Between-cohort demographic and clinical characteristics were balanced. The mean (SD) HbA1c and BMI values for French, German, and Italian patients were, respectively, 8.6 (1.4)%, 8.2 (1.4)%, 8.0 (0.8)%; 33.3 (6.1) kg/m2, 36.0 (7.2) kg/m2, and 32.6 (5.9) kg/m2. Conclusion This study analysis at baseline provides an opportunity to evaluate between-country differences in baseline HbA1c, weight, macrovascular complications, and factors driving GLP-1 RA selection for patients with T2DM in daily practice. Supplementary Information The online version contains supplementary material available at 10.1007/s13300-021-01076-0., Plain Language Summary Dulaglutide and liraglutide are medications that can help people with type 2 diabetes mellitus (T2DM) to control their blood sugar levels. These medications may also reduce body weight and reduce the risk of major cardiovascular disease. Given these treatment effects, it is essential to know how they are used in everyday clinical practice. Therefore, a study is being performed in three countries (France, Germany, and Italy) in people with T2DM who had a first-ever injectable therapy for T2DM with dulaglutide or liraglutide. Here, we present the study design, the patient characteristics at the start of treatment, and the factors driving the choice of one or the other medication. We analyzed data from 2181 people with T2DM. On average, it was shown that they were middle-aged and obese. On average, these people were diagnosed with T2DM 8.5 years before the start of dulaglutide or liraglutide and had high blood sugar levels when these medications were started. The patient characteristics were slightly different between the three countries. Country-specific factors driving the choice of either medication were also identified. Supplementary Information The online version contains supplementary material available at 10.1007/s13300-021-01076-0.

Aim To examine the efficacy and safety of glucagon-like peptide-1 receptor agonists (GLP-1RAs) and sodium-glucose cotransporter-2 (SGLT2) inhibitors compared with other antihyperglycaemic agents (AHAs) in large and unselected populations of the Lombardy and Apulia regions in Italy. Materials and methods An observational cohort study of first-time users of GLP-1RAs, SGLT2 inhibitors or other AHAs was conducted from 2010 to 2018. Death and cardiovascular (CV) events were evaluated using conditional Cox models in propensity-score-matched populations. Adjusted hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated for each region and in a meta-analysis for pooled risks. Results After propensity-score matching, the Lombardy cohort included 18 716 and 11 683 patients and the Apulia cohort 9772 and 6046 patients for the GLP-1RA and SGLT2 inhibitor groups, respectively. Use of GLP-1RAs was associated with lower rates of death (HR 0.61, CI 0.56-0.65, Lombardy; HR 0.63, CI 0.55-0.71, Apulia), cerebrovascular disease and ischaemic stroke (HR 0.70, CI 0.63-0.79; HR 0.72, CI 0.60-0.87, Lombardy), peripheral vascular disease (HR 0.72, CI 0.64-0.82, Lombardy; HR 0.80, CI 0.67-0.98, Apulia), and lower limb complications (HR 0.67, CI 0.56-0.81, Lombardy; HR 0.69, CI 0.51-0.93, Apulia). Compared with other AHAs, SGLT2 inhibitor use decreased the risk of death (HR 0.47, CI 0.40-0.54, Lombardy; HR 0.43, CI 0.32-0.57, Apulia), cerebrovascular disease (HR 0.75, CI 0.61-0.91, Lombardy; HR 0.72, CI 0.54-0.96, Apulia), and heart failure (HR 0.56, CI 0.46-0.70, Lombardy; HR 0.57, CI 0.42-0.77, Apulia). In the pooled cohorts, a reduction in heart failure was also observed with GLP-1RAs (HR 0.89, 95% CI 0.82-0.97). Serious adverse events were quite low in frequency. Conclusion Our findings from real-world practice confirm the favourable effect of GLP-1RAs and SGLT2 inhibitors on death and CV outcomes across both regions consistently. Thus, these drug classes should be preferentially considered in a broad type 2 diabetes population beyond those with CV disease.

Background: Type 2 diabetes poses an economic burden to healthcare systems. For individuals with non-intensively treated T2DM, it is unclear whether the use of CGM would add health-economic value. The aim of this study was to compare the costs of SMBG compared to CGM in non-intensively treated T2DM. Methods: A retrospective cost-analysis using the IBM® MarketScan® Databases was conducted. T2DM patients aged ≥18 years who were using SMBG or initiated CGM between Jan 2018 and March 20were eligible for inclusion. Inclusion criteria included two consecutive claims for T2DM or one claim for T2DM and a claim for glucose lowering therapy, at least one pharmacy claim for SMBG strips or CGM sensors and continuous enrollment for 1-year before and after the index date. Individuals with CGM in pre-index period, pregnancy, rapid-acting insulin, glucagon, T1DM, gestational or secondary diabetes were excluded. SMBG and CGM patients were matched using a propensity score and all cause costs during a one-year follow-up period were compared. Results: A total of 3,498 patients were included in each matched cohort. For CGM patients, 77% used flash monitoring and 23% a real-time CGM. 35% of SMBG and 37% of CGM users were on basal insulin. Considering median values, SMBG total healthcare costs per person/year were $1,934 less vs. CGM users (p < 0.05) . SMBG patients had significantly lower pharmacy cost (-$2,257, p Conclusion: This analysis shows that SMBG is less costly than CGM in non-intensively treated T2DM patients and is associated with lower pharmacy costs, including glucose-lowering medications. Furthermore, no significant differences in the number of emergency room visits or hospitalizations are seen in SMBG and CGM users. Disclosure D.

Introduction: SoliMix (EudraCT: 2017-003370-13) found better HbA1c, weight benefit, and lower hypoglycemia risk with iGlarLixi vs. premix BIAsp 30 in people with type 2 diabetes (T2D) advancing from basal insulin (BI) + oral antihyperglycemic drugs (OADs) . Methods: Adults with T2D and HbA1c 7.5-10.0 % on BI + 1-2 OADs were randomized to once-daily iGlarLixi or twice-daily BIAsp 30 for 26 weeks. Primary outcomes were non-inferiority in HbA1c change or superiority in body weight change from baseline to Week 26. SoliMix endpoints were assessed here by baseline age ( Results: No differences in treatment effect were observed across subgroups for HbA1c or body weight changes (heterogeneity p>0.05; Table) ; both primary objectives were met in the age, T2D duration, and the eGFR ≥60-0.80) . The advantage of iGlarLixi over BIAsp 30 for Level 2 hypoglycemia was found in all subgroups with no difference in treatment effect (p>0.10) . Conclusions: The primary findings for iGlarLixi vs. BIAsp 30 were unaffected by baseline age, T2D duration, or renal function.

TROPHIES was a 24-month, prospective, non-comparative, observational study in adult patients with T2D initiating their first injectable glucose-lowering treatment with once-weekly dulaglutide (DU; N=1,014) or once-daily liraglutide (LIRA; N=991) in France, Germany, and Italy. Secondary objectives included assessments of HbA1c, body weight and treatment patterns. Clinical characteristics of the DU and LIRA cohorts at 24 months are described in the Table. Most patients receiving DU (856/1,014) initiated treatment at 1.5 mg/week and, among 286 patients with a significant treatment change, 237 were still receiving 1.5 mg/week. In the LIRA cohort, most patients (809/991) initiated at the starting dose 0.6 mg/day and 45% increased dose to 1.2 mg/day by Day 90; however, 17% of patients were already receiving 1.8 mg/day by Day 90. At the first significant treatment change 285/448 patients in the LIRA cohort were receiving 1.2 mg/day. Insulin was initiated by 79 and 97 patients in the DU and LIRA cohorts, respectively. Both treatments showed clinically meaningful effectiveness on HbA1c and weight, maintained over the 24-month study period. Disclosure B. Guerci: Advisory Panel; Amgen Inc., Medtronic.

Introduction: SoliMix (EudraCT: 2017-003370-13) found better HbA1c, weight benefit, and lower hypoglycemia risk requiring less insulin with once-daily iGlarLixi vs. twice-daily premix BIAsp 30 in people with type 2 diabetes (T2D) advancing from basal insulin (BI) and oral antihyperglycemic drugs (OADs) . Methods: Adults with T2D and HbA1c 7.5-% on BI + 1-2 OADs were randomized to iGlarLixi or BIAsp 30 for 26 weeks. Primary outcomes were non-inferiority in HbA1c change or superiority in body weight change with iGlarLixi vs. BIAsp 30. This post hoc analysis assessed SoliMix endpoints by baseline HbA1c (7.5-8, >8-9, >9-%) , insulin dose ( Results: No differences in treatment effect were seen across subgroups for change in HbA1c or BMI (heterogeneity p>0.10; Table) ; both primary objectives were met in the HbA1c >8-≤9 %, BMI ≥25-0.10) . Level 2 hypoglycemia incidence and rates were unaffected by baseline HbA1c and BMI (p>0.10) , but p Conclusions: Primary SoliMix findings for iGlarLixi vs. BIAsp 30 were consistent across baseline HbA1c and BMI subgroups but inconsistent for baseline insulin dose.

Elevated saturated fatty acid deposition in the heart results in insulin resistance, stress kinase activation, and increased cardiovascular risk in humans. The viability of human cardiac progenitor cells (hCPC) is essential for myocardium homeostasis. This study investigates the ability of palmitate, a saturated fatty acid, to impair insulin signaling in hCPC isolated from right auricle biopsies, and the potential protective effects of oleate, a mono-unsaturated fatty acid. hCPC were found to express both insulin receptor (IR) isoforms, IR-A and IR-B, with higher IR-A:IR-B ratio. Exposure of hCPC to 100 nM insulin for 15 min induced Akt (S473) phosphorylation (p In conclusion, oleate prevents the palmitate-induced abnormalities in insulin signaling in hCPC, largely by counteracting p38 MAPK and JNK activation. Hence, oleate supplementation might limit lipotoxicity, thus contributing to cardiac protection. Disclosure R.Doria: None.

TROPHIES was a 24-month, prospective, non-comparative, observational study in adult patients with T2D initiating their first injectable glucose-lowering treatment with once-weekly dulaglutide (DU; N=1,014) or once-daily liraglutide (LIRA; N=991) in France, Germany, and Italy. Primary objective: to assess the time patients remained on their first GLP-1 RA without a significant treatment change due to treatment- or diabetes-related factors. Kaplan-Meier (KM) probability (95% CI) of no significant treatment change at 24 months was 0.71 (0.68-0.74) and 0.53 (0.49-0.56) in the DU and LIRA cohorts, respectively (Figure) . Two-hundred and eighty-six (28.2%) and 448 (45.2%) patients receiving DU and LIRA, respectively, had a significant treatment change. The main driver of treatment change in the DU and LIRA cohorts was intensification with an add-on therapy (insulin or OAD) and intensification with dose increase of GLP-1 RA, respectively. KM probability (95% CI) of GLP-1 RA persistence at 24 months was high in both cohorts: DU 0.82 (0.80-0.85) ; LIRA 0.75 (0.72-0.78) . In summary, the probabilities of no significant treatment change over 24 months were estimated as higher in the DU cohort than in the LIRA cohort in this non-comparative analysis, with good persistence in both cohorts.

Dysfunction of visceral and epicardial adipose tissue may alter heart performance and promote adverse cardiovascular outcomes in obesity and diabetes. We assessed whether the secretome from abdominal visceral (AV) and epicardial (E) adipose stem cells (ASC) and from AV mature adipocytes might affect the viability of human cardiac progenitor cells (hCPC) in human obesity, and the effects of dapagliflozin (DAPA) , a selective SGLT-2 inhibitor. ASC and mature adipocytes were isolated from AV and E adipose tissue biopsies of obese (Ob) and non-obese subjects, respectively. hCPC were isolated from right auricle biopsies of non-Ob, non-diabetic donors. hCPC were pretreated with uM DAPA for 24 h or left untreated, and then exposed to the conditioned media (CM) of AV-ASC, E-ASC, and AV mature adipocytes. The CM of AV-ASC, E-ASC, and AV mature adipocytes induced apoptosis, assessed by ELISA for cytoplasmic oligonucleosomes, in hCPC after 24 h (p In conclusion, in human obesity, the secretome of both AV and E ASC and mature adipocytes induces stress kinase activation in hCPC and impairs their viability and functionality, and these effects can be counteracted by SGLT-2 inhibitors directly acting on the hCPC.

Data on patient-reported outcome (PRO) measures in people living with T2D who initiate injectable glucagon-like peptide-1 receptor agonist (GLP-1 RA) medication in routine clinical practice are limited. Here we present final PRO data from the TROPHIES 24-month, prospective, non-comparative, observational study of adult patients with T2D in France, Germany and Italy who started their first injectable GLP-1 RA with either once-weekly dulaglutide (DU) or once-daily liraglutide (LIRA) . Patients’ scores on PRO questionnaires were assessed every 6 months. We present scores at 24 months compared with baseline values before starting DU or LIRA treatment. For each PRO measure, higher scores reflect better outcomes. Baseline characteristics (previously published) for patients prescribed DU (N=1,014) or LIRA (N=991) were similar between groups. Mean changes from baseline to 24 months in PRO scores indicate improvements in health outcomes in patients initiating DU or LIRA (Table) . In summary, among those patients still evaluable at 24 months we observed improvements in PRO scores from baseline in both groups, but with a more pronounced trend of improvement in the DU cohort for EQ-5D-5L VAS, IW-SP, DTSQs total, and DPM life and work productivity scores.

Introduction: The SoliMix trial (EudraCT: 2017-003370-13) found better HbA1c with weight benefit and lower hypoglycemia risk for iGlarLixi vs. premix BIAsp 30 in people with type 2 diabetes advancing from basal insulin plus oral antihyperglycemic drugs. This exploratory analysis investigated whether hypoglycemia influenced insulin titration and achievement of fasting plasma glucose (FPG) targets with each therapeutic option. Methods: Total insulin dose changes from baseline to Week 12 were stratified by hypoglycemia (yes/no) in each treatment arm and ADA Level 2 hypoglycemia ( Results: Lesser insulin dose increases occurred in both treatment groups for those who experienced hypoglycemia (mean ± SD iGlarLixi: 3.9 ± 12.5 U; BIAsp 30: 11.0 ± 18.8 U) vs. those who did not (mean ± SD iGlarLixi: 11.2 ± 9.9 U; BIAsp 30: 19.4 ± 19.3 U) . While higher FPG at Week 12 correlated with greater event rates of hypoglycemia in both treatment arms, event rates were higher for BIAsp 30 than for iGlarLixi irrespective of FPG (Figure) . Conclusions: More frequent hypoglycemia with premix BIAsp 30 than with iGlarLixi may result in lower insulin doses, thus hampering insulin titration and resulting in higher FPG.

A significant portion of pregnant women with Gestational Diabetes Mellitus (GDM) eventually requires insulin therapy, thus necessitating closer monitoring. In this study, we assessed a predictive model for the need of insulin therapy in women with GDM. In a retrospective cohort study, baseline data from 246 women with GDM (43% on subsequent insulin therapy, 57% on nutritional therapy alone) were analyzed using logistic regression. Diagnosis of GDM in previous pregnancies, previous GDM managed with insulin therapy, previous maternal impaired fasting glucose, fasting serum glucose diagnostic for GDM, and 0h and 2h diagnostic values at 75-g oral glucose tolerance test were independent qualitative significant predictors for subsequent insulin therapy. Pre-conceptional maternal body mass index, fasting serum glucose, HbA1c and gestational age at GDM diagnosis were independent quantitative significant predictors for subsequent insulin therapy. According to the odds ratios produced by the logistic regression, a risk score was developed, with identification of low (score Disclosure M.Caporusso: Other Relationship; Eli Lilly and Company.

Irisin is a hormone secreted by skeletal muscle following exercise or excess of saturated fatty acids (SFAs) , able to improve metabolic homeostasis and promote energy expenditure. Serum irisin levels are reduced in type 2 diabetes (T2D) , while exogenous irisin administration improves glycemic control in diabetic mice. We have previously demonstrated that irisin protects human and rodent β-cells and pancreatic islets from SFAs-induced apoptosis, increases insulin biosynthesis and glucose-stimulated insulin secretion (GSIS) , and promotes β-cell proliferation, both in vitro and in vivo in healthy wild-type mice. Irisin may also restore the defective GSIS and reduce the high rate of apoptosis that are characteristic of islets from T2D patients. However, the β-cellular effects of irisin administration to diabetic mice are still unknown. 6 weeks-old C57Bl/6 mice (n = 8) were fed a high-fat diet (HFD, 60% of energy deriving from fat) for weeks and then intraperitoneally injected with streptozotocin (STZ, 100 mg/Kg) to induce diabetes. 4 standard diet (SD) -fed mice were used as control. HFD/STZ mice were then treated with 0.5 μg/g irisin (n = 4) or vehicle (n = 4) for 14 days. Glucose tolerance, glycemia, insulinemia, body weight, pancreatic islet architecture and function were assessed throughout the study. As expected, compared to SD mice, HFD/STZ mice showed higher glycemia and body weight, glucose intolerance, and reduced GSIS; in addition, HFD/STZ mice showed reduced islet volume (-78%) , β-cell area (-35%) , and insulin content (-60%) , while increased α-cell area (+54%) . Irisin administration significantly restored glycemia (-31%) , body weight (-13%) , glucose tolerance (-27%, AUC) , GSIS (+23%, AUC) , islet volume (+61%) , β-cell (+34%) and α-cell (-49%) areas, and insulin content (+36%) . Of note, irisin treatment induced a 9-fold increase in β-cell proliferation rate. These results show for the first time that irisin can restore β-cell functional mass when administered in vivo to diabetic mice. Disclosure N.Marrano: None. G.Biondi: None. A.Borrelli: None.

We evaluated the role of the p66Shc redox adaptor protein in pancreatic beta-cell insulin resistance that develops under lipotoxic conditions and with excess body fat. Prolonged exposure to palmitate in vitro or the presence of overweight/obesity augmented p66Shc expression levels and caused an impaired ability of exogenous insulin to increase cellular insulin content and secreted C-peptide levels in INS-1E cells and human and murine islets. In INS-1E cells, p66Shc knockdown resulted in enhanced insulin-induced augmentation of insulin content and C-peptide secretion and prevented the ability of palmitate to impair these effects of insulin. Conversely, p66Shc overexpression impaired insulin-induced augmentation of insulin content and C-peptide secretion both in the absence and presence of palmitate. Under lipotoxic condition, the effects of p66Shc are mediated by p53-induced increase in p66Shc protein levels and JNK-induced p66Shc phosphorylation at Ser36 and appear to involve the phosphorylation of the ribosomal protein S6 kinase at Thr389 and of insulin receptor substrate-1 at Ser307, resulting in the inhibition of insulin-stimulated protein kinase b phosphorylation at Ser473. Thus, the p66Shc protein mediates the impaired beta-cell function and insulin resistance induced by saturated fatty acids and excess body fat.

Obesity is a chronic disease caused by an excess of adipose tissue that may impair health by altering the functionality of various organs, including the lungs. Excessive deposition of fat in the abdominal area can lead to abnormal positioning of the diaphragm and consequent reduction in lung volume, leading to a heightened demand for ventilation and increased exposure to respiratory diseases, such as chronic obstructive pulmonary disease, asthma, and obstructive sleep apnoea. In addition to mechanical ventilatory constraints, excess fat and ectopic deposition in visceral depots can lead to adipose tissue dysfunction, which promotes metabolic disorders. An altered adipokine-secretion profile from dysfunctional adipose tissue in morbid obesity fosters systemic, low-grade inflammation, impairing pulmonary immune response and promoting airway hyperresponsiveness. A potential target of these adipokines could be the NLRP3 inflammasome, a critical component of the innate immune system, the harmful pro-inflammatory effect of which affects both adipose and lung tissue in obesity. In this review, we will investigate the crosstalk between adipose tissue and the lung in obesity, highlighting the main inflammatory mediators and novel therapeutic targets in preventing pulmonary dysfunction.

The dysregulation of the β-cell functional mass, which is a reduction in the number of β-cells and their ability to secure adequate insulin secretion, represents a key mechanistic factor leading to the onset of type 2 diabetes (T2D). Obesity is recognised as a leading cause of β-cell loss and dysfunction and a risk factor for T2D. The natural history of β-cell failure in obesity-induced T2D can be divided into three steps: (1) β-cell compensatory hyperplasia and insulin hypersecretion, (2) insulin secretory dysfunction, and (3) loss of β-cell mass. Adipose tissue (AT) secretes many hormones/cytokines (adipokines) and fatty acids that can directly influence β-cell function and viability. As this secretory pattern is altered in obese and diabetic patients, it is expected that the cross-talk between AT and pancreatic β-cells could drive the maintenance of the β-cell integrity under physiological conditions and contribute to the reduction in the β-cell functional mass in a dysmetabolic state. In the current review, we summarise the evidence of the ability of the AT secretome to influence each step of β-cell failure, and attempt to draw a timeline of the alterations in the adipokine secretion pattern in the transition from obesity to T2D that reflects the progressive deterioration of the β-cell functional mass.
