  • Widefield optical coherence tomography angiography in diabetic retinopathy
    • Abstract: Aims To evaluate superficial capillary plexus (SCP), deep capillary plexus (DCP) and choriocapillaris (CC) perfusion in macular and near/mid periphery regions in diabetic patients using widefield swept-source optical coherence tomography angiography (WSS-OCTA). Methods Ninety-four diabetic patients (94 eyes) classified as diabetics without diabetic retinopathy (no DR) (25 eyes), mild DR (23 eyes), moderate/severe DR (26 eyes), proliferative DR (20 eyes) and a control group of 25 healthy subjects (25 eyes) were imaged with the WSS-OCTA system (PLEX Elite 9000, Carl Zeiss Meditec Inc., Dublin, CA, USA). Quantitative analysis was performed in the macular and peripheral regions. The main outcome measures were perfusion density (PD) and vessel length density of SCP, DCP and CC. Results Peripheral retina (all sectors) showed lower SCP and DCP PD compared to the macular region (p  < 0.001). In diabetics without DR and DR in different stages, SCP and DCP PD significantly decreased at advancing stages of DR (p  < 0.001). At DCP level, central PD was significantly directly related to peripheral PD (superior, R = 0.682 and 0.479; temporal, R  = 0.918 and 0.554; inferior, R  = 0.711). A good sensitivity and an excellent specificity were found in terms of prediction of disease worsening, especially for central and temporal sectors in all plexuses and for all sectors both central and peripheral of DCP. Conclusions The widefield OCTA is useful for the study of central and peripheral retina in diabetic patients with or without diabetic retinopathy, assessing good correlation between central and peripheral retina.

  • Alcohol consumption or cigarette smoking and cardiovascular disease risk
           in youth with type 1 diabetes
    • Abstract: Aim To assess the association between alcohol consumption and/or cigarette smoking with other unhealthy behaviors and clinical cardiovascular risk factors in youth with type 1 diabetes. Methods Two hundred and twenty-eight youth with type 1 diabetes (age 13–19 years) were consecutively enrolled in three Regional Pediatric Diabetes Centers in Italy. Demographic, anthropometric, lifestyle (adherence to the Mediterranean diet pattern and sports participation) and laboratory parameters were compared among youth reporting isolated or combined alcohol consumption and/or cigarette smoking. Results Ten percent of the youth reported alcohol consumption, 10% cigarette smoking and 6% both alcohol and cigarette use; 74% did not report alcohol or cigarette use. Compared to non-drinker non-smoker youth, smokers showed significantly higher percentages of each of the behavioral and clinical cardiovascular risk factors. Drinkers showed a significantly higher proportion of abdominal adiposity, dyslipidemia and poor adherence to the Mediterranean diet. Alcohol consumption was independently associated with both dyslipidemia and high glycosylated hemoglobin. Conclusions Our findings emphasize the need to increase the awareness of youth with T1D about the negative impact of alcohol drinking on cardiovascular risk, since the effects of alcohol might be underestimated with respect to the well-known detrimental effects of smoking. Clustering of unhealthy lifestyle should be discouraged in type 1 diabetes youth in order to promote cardiovascular protection.

  • Timp3 deficiency affects the progression of DEN-related hepatocellular
           carcinoma during diet-induced obesity in mice
    • Abstract: Aim Obesity and low-grade inflammation are associated with an increased risk of hepatocellular carcinoma (HCC), a leading cause of cancer-related death worldwide. The tissue inhibitor of metalloproteinase (TIMP) 3, an endogenous inhibitor of protease activity that represents a key mediator of inflammation, is reduced in inflammatory metabolic disorders and cancer. In contrast, Timp3-deficient mice (Timp3−/−) are highly resistant to developing HCC in response to a diethylnitrosamine (DEN); therefore, we aimed to elucidate the biological role of genetic loss of Timp3 in obesity-related hepatocarcinogenesis. Methods Fourteen-day-old male wild-type (wt) and Timp3−/− mice were injected with 25 mg/kg DEN or an equal volume of saline. After 4 weeks, mice were randomized into two dietary groups and fed either normal or high-fat diet and allowed to grow until 32 weeks of age. Liver histological features were analyzed, and differentially expressed genes in the liver were quantified. Results In Timp3−/− mice fed with the obesogenic diet, despite the increase in liver steatosis and inflammation, both the number of tumors and the total tumor size are significantly reduced 30 weeks post-DEN injection, compared to control mice. Moreover, Timp3 deletion in hepatocarcinogenesis during obesity is associated with a reduction in FoxM1 transcriptional activity through H19/miR-675/p53 pathway. Conclusions This study suggests that Timp3 ablation leads to cell cycle perturbation, at least in part by repressing FoxM1 transcriptional activity through H19/miR-675/p53 pathway.

  • Lipid nanoparticles as vehicles for oral delivery of insulin and insulin
           analogs: preliminary ex vivo and in vivo studies
    • Abstract: Aims Subcutaneous administration of insulin in patients suffering from diabetes is associated with the distress of daily injections. Among alternative administration routes, the oral route seems to be the most advantageous for long-term administration, also because the peptide undergoes a hepatic first-pass effect, contributing to the inhibition of the hepatic glucose output. Unfortunately, insulin oral administration has so far been hampered by degradation by gastrointestinal enzymes and poor intestinal absorption. Loading in lipid nanoparticles should allow to overcome these limitations. Methods Entrapment of peptides into such nanoparticles is not easy, because of their high molecular weight, hydrophilicity and thermo-sensitivity. In this study, this objective was achieved by employing fatty acid coacervation method: solid lipid nanoparticles and newly engineered nanostructured lipid carriers were formulated. Insulin and insulin analog—glargine insulin—were entrapped in the lipid matrix through hydrophobic ion pairing. Results Bioactivity of lipid entrapped peptides was demonstrated through a suitable in vivo experiment. Ex vivo and in vivo studies were carried out by employing fluorescently labelled peptides. Gut tied up experiments showed the superiority of glargine insulin-loaded nanostructured lipid carriers, which demonstrated significantly higher permeation (till 30% dose/mL) compared to free peptide. Approximately 6% absolute bioavailability in the bloodstream was estimated for the same formulation through in vivo pharmacokinetic studies in rats. Consequently, a discrete blood glucose responsivity was noted in healthy animals. Conclusions Given the optimized ex vivo and in vivo intestinal uptake of glargine insulin from nanostructured lipid carriers, further studies will be carried out on healthy and diabetic rat models in order to establish a glargine insulin dose–glucose response relation.

           activity and hypothalamic gliosis in patients with type 2 diabetes
           mellitus: a proof-of-concept study
    • Abstract: Aims This study aimed to evaluate the effect of pioglitazone on brown adipose tissue function and hypothalamic gliosis in humans. Brown adipose tissue and the hypothalamus are regarded as important potential pharmacological targets to metabolic diseases, and defining the impact of current therapies on their structure and/or function could provide therapeutic advance in this field. Methods Six patients with type 2 diabetes were treated for 24 weeks with pioglitazone 30 mg/day as an add-on therapy. Brown adipose tissue glucose uptake and volume were determined using 18F-FDG PET/CT scans; hypothalamic gliosis was determined using MRI scans; blood was collected for hormone and biochemistry measurements. All tests were performed at inclusion and six months after pioglitazone introduction. Results Pioglitazone treatment led to a significant 3% body mass increase. There were neither changes in cold-induced brown adipose tissue glucose uptake and volume nor changes in hypothalamic gliosis. Conclusions This is a proof-of-concept study that provides clinical evidence for a lack of action of a thiazolidinedione, pioglitazone, to promote homogeneous and measurable changes in brown adipose tissue volume and also in hypothalamic gliosis after 6 months of treatment.

  • Hemodialysis biomarkers: total advanced glycation end products (AGEs)
           against oxidized human serum albumin (HSAox)
    • Abstract: Aims Nephropathic patients show higher levels of advanced glycation end products (AGEs) and oxidized human serum albumin (HSAox) compared to healthy subjects. These two classes of compounds are formed as the result of oxidative insults; for this reason, they can be useful oxidative stress biomarkers. The present study examines the variation of AGEs and HSAox in hemodialysis (HD) patients before and after dialysis session, evaluating the impact of different dialytic techniques and filters on their removal. Methods A total of 50 healthy subjects (control group) and 130 HD patients were enrolled in the study. Hemodialysis patients were subdivided based on dialytic techniques: 109 in diffusive technique and 22 in convective technique. We monitored HSAox, AGEs and other laboratory parameters at early morning in healthy subjects and in HD patients before and after the dialysis procedures. Results The level of HSAox decreases after a single dialytic session (from 58.5 ± 8.8% to 41.5 ± 11.1%), but the concentration of total AGEs increases regardless of adopted dialytic techniques (from 6.8 ± 5.2 µg/ml to 9.2 ± 4.4 µg/ml). In our study, levels of HSAox and total AGEs are similar in diabetic and non-diabetic HD patients. The increase in total AGEs after dialysis was only observed using polysulfone filters but was absent with polymethacrylate filters. Conclusions HSAox is a simple and immediate method to verify the beneficial effect of a single dialysis session on the redox imbalance, always present in HD patients. Total AGEs assayed by ELISA procedure seem to be a less reliable biomarker in this population.

  • Real-world outcomes of non-responding diabetic macular edema treated with
           continued anti-VEGF therapy versus early switch to dexamethasone implant:
           2-year results
    • Abstract: Aims To provide 2-year follow-up data on eyes with diabetic macular edema (DME) that were non-responsive after three initial anti-vascular endothelial growth factor (VEGF) injections, comparing functional and anatomical outcomes under continued anti-VEGF therapy versus dexamethasone (DEX) implant. Methods Multicenter, retrospective chart review comparing eyes with treatment-naïve DME and a suboptimal response to a loading phase of anti-VEGF therapy (3 injections given monthly) which were then treated with (a) further anti-VEGF (n = 72) or (b) initially switched to DEX implant (n = 38). Main outcome measures were change in visual acuity (VA) and central subfield thickness (CST) from the end of the loading phase to 24 months. Results In 79% of the 12-month study population (87/110 eyes), 24-month data were available. One quarter of eyes in each group switched treatments during the second year. Eyes that were switched early to DEX implant maintained the functional and anatomical improvements at 24 months which were seen in the first year (from month 3: + 8.9 letters, − 214 µm). Eyes that were switched from anti-VEGF therapy to steroids in the second year improved VA and reduced CST at 24 months (from month 12: + 6.8 letters, p = 0.023; − 226 µm, p = 0.004). In eyes continued on anti-VEGF therapy, VA and CST were stable at 24 months (from month 3: + 2.8 letters, p = 0.254; − 24 µm, p = 0.243). Eyes that were non-responsive to anti-VEGF therapy for 12 months had similar chances to experience a VA gain from further therapy as eyes that were non-responsive for 3 months only (23.8 vs. 31.0%, p = 0.344). Conclusions The beneficial effect of an early switch to DEX implant in DME non-responders seen at month 12 was maintained during the second year. A later switch from anti-VEGF to steroids still provided significant improvement. Eyes continued on anti-VEGF over a period of 24 months maintained vision. A quarter of eyes, which had not improved vision at 12 months, exhibited a delayed response to treatment.

  • Mortality in Asian Indians with Charcot’s neuroarthropathy: a nested
           cohort prospective study
    • Abstract: Aims We studied mortality in individuals of diabetes with or without Charcot neuroarthropathy (CN). Methods People attending diabetic foot care facility with CN of foot (Cohort 1) were prospectively evaluated. Details pertaining to the duration of diabetes, microvascular and macrovascular complications, foot ulcer, amputation and mortality outcomes were recorded and compared with those without foot complications (Cohort 2) by multivariate logistic regression. Results Data for 260 individuals of diabetes with CN and 520 individuals without CN were analysed. Mean age at presentation with CN was 55.8 ± 9.1 years, and duration of diabetes was 12.9 ± 7.8 years. 39.8% individuals with CN had foot ulcer, and 15.3% had amputation. People with CN were younger (55 ± 9.1 vs. 59.9 ± 8.1 years, p < 0.001) and had higher prevalence of microvascular complications. A total of 39 (15%) individuals with CN and 50 (9.8%) (p = 0.03) individuals without CN died during median follow-up of 40(24–51) months. People with CN had 2.7 times (OR 2.72, 95% CI 1.4–5.2, p = 0.003) increased mortality risk when matched for potential confounders. Prevalent CAD and low eGFR predicted higher mortality in people with CN. Conclusions People with Charcot neuroarthropathy have almost three times increased risk of mortality despite being younger at presentation.

  • Pancreatic β-cell dysfunction in normoglycemic patients and risk
    • Abstract: Aims To evaluate pancreatic β-cell function (βf) in patients with normoglycemia (NG) and normal glucose tolerance (NGT) and related risk factors. Methods An observational and comparative study in 527 patients with NG and NGT that were divided by quartiles of βf according to the disposition index derived from OGTT. Anthropometrical, clinical, nutritional, and biochemical variables were measured and associated with βf. Results Quartiles of βf were Q1 = DI < 1.93 n = 131, Q2 = DI 1.93–2.45 n = 134, Q3 = DI 2.46–3.1 n = 133, and Q4 = DI > 3.1 n = 129. There was a progressive reduction in pancreatic β-cell function and it is negatively correlated with age, weight, BMI, total body fat and visceral fat, waist circumference, total cholesterol, LDL, and triglycerides (p < 0.01). Glucose levels during OGTT had a negative correlation with βf; the product of fasting glucose by 1-h glucose had the best correlation with βf (r = 0.611, p < 0.001) and was the best predictor of βdf (AUC 0.816, CI 95% 0.774–0.857), even better than 1-h glucose (r = 0.581, p < 0.001). Energy, fat, and carbohydrate intake were negatively correlated with βf (p < 0.05). Glucose levels at 1-h OGTT > 110 mg/dl were positively associated with pancreatic βdf (OR 6.85, CI 95% 3.86–12.4). In the multivariate analysis, glucose levels during OGTT, fasting insulin, and BMI were the main factors associated with βf. Conclusions A subgroup of patients with NG and NGT may have a loss of 40% of their βf. Factors related to this βdf were age, adiposity, glucose during OGTT, and the product of fasting and 1-h glucose, as well as food intake.

  • Progressive retinal neurodegeneration and microvascular change in diabetic
           retinopathy: longitudinal study using OCT angiography
    • Abstract: Aims To investigate the association between progressive macular ganglion cell/inner plexiform layer (mGCIPL) thinning and change of optical coherence tomography angiography (OCTA)-derived microvascular parameters in early-stage diabetic retinopathy (DR). Methods A retrospective cohort study involved 40 eyes presenting with no DR or mild non-proliferative DR at baseline, and 30 healthy controls were included. All participants underwent spectral-domain OCT and OCTA at baseline and at 6, 12, 18, and 24 months. Change of mGCIPL thickness and OCTA metrics including foveal avascular zone (FAZ) area and FAZ circularity, vessel density (VD), and perfusion index (PI) was measured. Correlations between mGCIPL thickness and OCTA metrics were explored using regression models. Results Average progressive mGCIPL loss was 0.45 µm per year. Three microvascular parameters were significantly impaired at 24 months compared to baseline (FAZ area: 0.34–0.36 mm2, VD: 18.9–18.5/mm, PI: 0.35–0.34). A strong positive correlation was found between loss of mGCIPL and VD from baseline to 24 months (r = 0.817, p < 0.001). Multivariable regression analysis showed that thinner baseline mGCIPL and greater loss of mGCIPL thickness (B = 0.658, p < 0.001) were significantly associated with change of VD. Conclusions In the early stage of DR, progressive structural retinal neurodegeneration and parafoveal microvascular change seem to be highly linked. Advanced mGCIPL thinning might precede microvascular impairment in early DR.

  • The multifaceted nature of diabetes mellitus induced by checkpoint
    • Abstract: Immune checkpoint inhibitors (CPI) are increasingly being used in oncology, and many autoimmune side effects have been described. Diabetes mellitus (DM) has been reported in approximately 1% of subjects treated with programmed cell death-1 and programmed death ligand 1 (PD-1/PD-L1) inhibitors, alone or in association with CTLA-4 inhibitors. In the present mini-review, we aimed to describe different clinical pictures and pathophysiology associated with these forms of diabetes. Data on CPI-related DM was gathered from the largest case series in the literature and from our centre dedicated to immunotherapy complications (ImmuCare—Hospices Civils de Lyon). Most cases are acute autoimmune insulin-dependent diabetes which are similar to fulminant diabetes (extremely acute onset with concomitant near-normal HbA1c levels). Other cases, however, have a phenotype close to type 2 diabetes or appear as a decompensation of previously known type 2 diabetes. The occurrence of diabetes can also be a complication of autoimmune pancreatitis induced by CPI use. Finally, two cases of diabetes in a context of autoimmune lipoatrophy have recently been described. Regarding the wide variety of CPI-induced diabetes, the discovery of a glucose disorder under CPI should motivate specialised care for aetiological diagnosis and appropriate treatment.

  • The continuous challenge of antithrombotic strategies in diabetes: focus
           on direct oral anticoagulants
    • Abstract: Direct oral anticoagulants (DOACs) include dabigatran, which inhibits thrombin, and apixaban, edoxaban, and rivaroxaban, which inhibit factor Xa. They have been extensively studied in large trials involving patients affected by the most common cardiovascular diseases. As the presence of diabetes leads to peculiar changes in primary and secondary hemostasis, in this review we highlight the current evidence regarding DOAC use in diabetic patients included in the majority of recently conducted studies. Overall, in trials involving patients with atrial fibrillation, data seem to confirm at least a similar efficacy and safety of DOACs compared to warfarin in patients with or without diabetes. Furthermore, in diabetic patients, treatment with DOACs is associated with a significant relative reduction in vascular death compared to warfarin. In trials enrolling patients undergoing percutaneous coronary intervention, results concerning bleeding events are consistent in patients with or without diabetes. With regards to the COMPASS study, in patients with diabetes (n = 10,241), addition of rivaroxaban 2.5 mg to aspirin resulted in a significantly lower incidence of major adverse cardiovascular events (HR 0.74, 95% CI 0.61–0.90; interaction p = 0.68) with higher rates of major bleeding expected (HR 1.70, 95% CI 1.25–2.31). The 3287 patients with peripheral artery disease and diabetes receiving rivaroxaban plus aspirin had a twofold higher absolute reduction in the composite endpoint (cardiovascular death, myocardial infarction, and stroke) than patients without diabetes. Finally, we report the involvement of cytochromes or P-glycoprotein on the metabolism of the most commonly prescribed glucose-lowering drugs. No clinically relevant interactions are expected during the concomitant use of DOACs and anti-diabetic agents.

  • “Out of the box” solution for skin problems due to glucose-monitoring
           technology in youth with type 1 diabetes: real-life experience with
           fluticasone spray
    • Abstract: Background Use of a continuous glucose-monitoring system (CGMS) in the management of type 1 diabetes (T1D) may cause local skin irritation. Objective To examine the effects of fluticasone propionate aqueous nasal solution (nsFP), sprayed topically prior to CGMS insertion among youth with T1D. Methods This is a case series observational report, including real-life 6-month follow-up data from one pediatric diabetes center. All patients suffering from local skin irritation due to CGMS adhesives were offered prevention form skin irritation by spraying 2 puffs of nsFP on the skin area prior to adhesion of CGMS. Data were collected from their charts after 6 months. Outcome measures included the difference in degree of skin irritation, number of days of CGMS use, BMI SDS, mean glucose, and HbA1c, prior to use and during 6 months after use. Results Twelve patients used nsFP prior to CGMS insertion, mean age 8.6 ± 4.9 years and 66.7% males. Ten patients, median age 6.1 years (5.3–9.5) and 56% males, continued using nsFP for a mean of 0.56 ± 0.11 years, with no recurrence of local irritation nor dermatitis to same adhesive material. No differences were found before and after use of nsFP in CGMS mean glucose 180 mg/dl (153–202) versus 165 mg/dl (150–192). BMI SDS was slightly higher 0.44 (− 0.9–1.2) versus 0.25 (− 0.47–1.06), P = 0.05. Conclusions This small-scale, single-site description of a simple intervention by nsFP and favorable outcome provides valuable insight for a simple solution for skin irritation and dermatitis in the pediatric population with T1D.

  • Cardiorespiratory fitness and right ventricular mechanics in uncomplicated
           diabetic patients: Is there any relationship'
    • Abstract: Aims This study investigated the association between cardiorespiratory fitness and right ventricular (RV) strain in uncomplicated diabetic patients. Methods This cross-sectional study involved 70 controls and 61 uncomplicated patients with type 2 diabetes, who underwent laboratory analysis, comprehensive echocardiographic study and cardiopulmonary exercise testing. Results RV endocardial and mid-myocardial longitudinal strains were significantly reduced in diabetic subjects (− 27.5 ± 4.2% vs. − 25.3 ± 4.3%, p = 0.004 for endocardial strain; − 25.6 ± 3.5% vs. − 24.1 ± 3.2%, p = 0.012 for mid-myocardial strain). The same was revealed for endocardial and mid-myocardial of RV free wall. There was no difference in RV epicardial strain. VO2 was significantly lower in the diabetic group (27.8 ± 4.5 ml/kg/min vs. 21.5 ± 4.2 ml/kg/min, p < 0.001), whereas ventilation/carbon dioxide slope was significantly higher in diabetic subjects (25.4 ± 2.9 vs. 28.6 ± 3.3). Heart rate recovery was significantly lower in diabetic patients. HbA1c and global RV endocardial longitudinal strain were independently associated with peak VO2 and oxygen pulse in the whole study population. Conclusion Diabetes impacts RV mechanics, but endocardial and mid-myocardial layers are more affected than epicardial layer. RV endocardial strain and HbA1c were independently associated with cardiorespiratory fitness in the whole study population. Our findings show that impairment in RV strain and cardiorespiratory fitness may be useful indicators in early type 2 diabetes, prior to the development of further complications.

  • Improved metabolic control using glucose monitoring systems leads to
           improvement in vibration perception thresholds in type 1 diabetes patients
    • Abstract: Aims Few studies have examined how improved metabolic control might influence vibration perception thresholds (VPTs). The aim of this study was to evaluate if improved HbA1c can influence vibration thresholds in adults with type 1 diabetes (T1DM). Methods VPTs were investigated at six frequencies (4–125 Hz) using VibroSense Meter in the sole of the foot at two occasions in 159 T1DM patients, at the heads of the first and fifth metatarsal bones, i.e. MTH1 and MTH5, respectively. The participants were divided into three groups: group A: HbA1c improved by more than 1 mmol/mol (n = 95), group B: HbA1c deteriorated by more than 1 mmol/mol (n = 48) and group C: HbA1c unchanged (± 1 mmol/mol) (n = 16) compared to baseline. Results In group A, the mean z-score, reflecting the combined effect of all VPTs, improved being lower at the follow-up than at the baseline [0.2 (− 0.3 to 1.2) vs. −0.1 (− 0.7 to 0.8), p = 0.00002]. VPTs improved at 4 and 64 Hz at both MTH1 (metatarsal head 1) and MTH5. The VPTs at 125 Hz frequency improved at MTH5, but not at MTH1. No significant differences were seen in group B or group C. Conclusions Lower HbA1c and lower VPTs in T1DM patients were associated with improved VPT, suggesting a reversible effect on nerve function by improved metabolic control.

  • The clinical significance of long non-coding RNA ANRIL level in diabetic
    • Abstract: Aim To analyse the expression of lncRNA-ANRIL and other related factors in different human body fluids, explore the clinical significance of ANRIL and validate whether ANRIL is interrelated with the renin–angiotensin system and NF-κB signalling pathway. Methods Ninety-one patients were included in this cross-sectional study and were divided into the NDM group (20 patients), DM group (25 patients), NPDR group (21 patients) and PDR group (25 patients). Basic information and samples of serum, aqueous fluid and vitreous fluid were collected before vitrectomy or intravitreal injection. The transcription and levels of ANRIL and other related factors were detected by RT-PCR and ELISA. Statistical Package for Social Sciences software was used for statistical analysis. Results ANRIL expression varied among different groups and body fluids. There was no difference in ANRIL expression between the NDM and DM groups, but the level of ANRIL was significantly lower in the DM group than in the NPDR and PDR group. In vitreous fluid, ANRIL expression was positively correlated with Ang II, p65 and VEGF expression in the PDR group. The expression of ANRIL in serum was not significantly correlated with age or the random blood sugar but was positively correlated with diabetic duration and HbAc1 level. Conclusions Levels of lncRNA-ANRIL are higher in DR patient and correlated with the progression of DR that may be used as an indicator to predict the development of DR. The activation of the RAS and the NF-κB pathway may be closely related to the upregulation of ANRIL. Clinical trial number ChiCTR1800017500. Registry Chinese Clinical Trial Registry.

  • Incretin-based therapy and risk of cholangiocarcinoma: a nested
           case–control study in a population of subjects with type 2 diabetes
    • Abstract: Background and aims One cohort and several basic science studies have raised suspicion about an association between incretin therapies and cholangiocarcinoma. Our aim was to verify the occurrence of CC in relation to incretin-based medication use versus any antidiabetic treatment in an unselected population of diabetic patients. Methods A population-based matched case–control study was conducted using administrative data from the Region of Piedmont (4,400,000 inhabitants), Italy. From a database of 312,323 patients treated with antidiabetic drugs, we identified 744 cases hospitalized for cholangiocarcinoma from 2010 to 2016 and 2976 controls matched for gender, age and initiation of antidiabetic therapy; cases and controls were compared for exposure to incretin-based medications. All analyses were adjusted for risk factors for CC, as ascertained by hospital discharge records. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated by fitting a conditional logistic model. Results The mean age of the sampled population (cases and controls, 75 years) was very high, with no gender prevalence. Five per cent was treated with incretin-based medications. After adjusting for possible confounders, we found no increased risk of cholangiocarcinoma associated with the use of either DPP4i (OR 0.98, 95% CI 0.75–1.29: p = 0.89) or GLP-1-RA (OR 1.09, 95% CI 0.63–1.89; p = 0.76) in the 24 months before hospital admission. Neither the duration of the therapy nor the dose modified the risk of cholangiocarcinoma. Conclusions Our findings suggest that, in an unselected population, the use of both classes of incretin-based medications is not associated with an increased risk of cholangiocarcinoma.

  • Platelet aggregation is not altered among men with diabetes mellitus
    • Abstract: Aims Platelets are pivotal in arterial thrombosis, and platelet hyperresponsiveness may contribute to the increased incidence of cardiovascular events in diabetes mellitus. Consequently, we hypothesized that increased in vitro platelet aggregation responses exist in men with diabetes mellitus. Methods The Danish Cardiovascular Screening Trial (DANCAVAS) is a community-based cardiovascular screening trial including men aged 65–74 years. Platelet aggregation was tested using 96-well light transmission aggregometry with thrombin receptor-activating peptide (TRAP), adenosine diphosphate, collagen type 1, arachidonic acid and protease-activated receptor-4 in three concentrations. Further, cardiovascular risk factors and coronary artery calcification (CAC), estimated by CT scans and ankle–brachial index, were obtained. Results Included were 720 men aged 65–74 years, 110 with diabetes mellitus. Overall, there was no difference in platelet aggregation among men with versus without diabetes mellitus when adjusting for or excluding platelet inhibitor treatment and men with established cardiovascular disease (CVD). This was true for all agonists, e.g., 10 µM TRAP-induced platelet aggregation of median 69% (IQR 53–75) versus 70% (IQR 60–76) in men with versus without diabetes mellitus. Platelet aggregation did not correlate with HbA1c or CAC. Men with diabetes mellitus displayed higher CAC, median 257 Agatston units (IQR 74–1141) versus median 111 Agatston units (IQR 6–420) in the remaining individuals, p < 0.0001. Conclusions Among outpatients with diabetes mellitus, but no CVD and no platelet inhibitor treatment, neither are platelets hyperresponsive in diabetes mellitus, nor is platelet aggregation associated with glycemic status or with the degree of coronary atherosclerosis. Trial Registration ISRCTN12157806.
