Abstract
Background
Various BP characteristics, e.g., systolic blood pressure (SBP), diastolic blood pressure (DBP), and pulse pressure (PP), as well as heart rate (HR) may affect the risk of both cardiovascular events and bleeding events. However, the exact way in which these characteristics and outcomes are associated among patients with diabetes and stable coronary artery disease (CAD) remains debated. Moreover, it is unknown whether the risks and benefits of intensified antiplatelet therapy in this patient population are affected by their baseline BP and HR.
Purpose
To assess the relationship between BP components (including HR) and cardiovascular and bleeding events, and to determine if the effects of ticagrelor vs. placebo varied across the BP and HR spectrum, in patients with diabetes and stable CAD.
Methods
THEMIS was a randomized, controlled trial in which 19,220 individuals ≥50 years of age with stable CAD and type 2 diabetes were randomized to receive either ticagrelor plus aspirin or placebo plus aspirin. Patients with a prior myocardial infarction or stroke, or already on dual antiplatelet therapy, were excluded. The primary efficacy outcome was a composite of cardiovascular death, myocardial infarction, or stroke. The primary safety outcome was TIMI major bleeding. We examined prognostic implications of BP components using 1) restricted cubic splines for the overall trends with outcomes; 2) Cox proportional-hazards regression models with predefined BP component intervals adjusted for demographic, clinical, and laboratory variables; and 3) Cox regression models for the effects of ticagrelor vs. placebo on outcomes across the spectrum of BP component values (test for interaction). THEMIS is registered at ClinicalTrials.gov (NCT01991795).
Results
Mean values of baseline BP components were similar between the two study groups. Median follow-up duration was 39.9 months (range 0–57), with 1554 primary efficacy events and 306 primary safety events occurring over the course of the study. All BP components (including HR) displayed various, independent relationships with the tested outcomes. For example, in adjusted spline models, SBP displayed non-linear relationships with the primary outcome, all-cause death, any bleeding, serious adverse events, and intracranial bleeding, and linear relationships with the remaining outcomes. Figure 1 shows the associations of each BP component with the primary efficacy outcome. BP components did not substantially modify the risks and benefits of ticagrelor vs. placebo for the tested outcomes.
Conclusions
BP components were independently associated with efficacy and safety outcomes in patients with stable CAD and type 2 diabetes. However, no important modification of BP components on the effect of ticagrelor vs. placebo was detected.

Abstract
Abstract
Background
Inflammation plays an important role in atherosclerosis. The neutrophil-to-lymphocyte ratio (NLR) may serve as a clinically useful biomarker of inflammation and cardiovascular (CV) disease, although this relationship has not been studied in people with type 2 diabetes (T2D).
Purpose
This post hoc analysis investigated the relationship between NLRs and CV outcomes in T2D CV outcomes trials for two formulations of semaglutide, a glucagon-like peptide-1 receptor agonist.
Methods
In pooled analyses of the SUSTAIN 6 and PIONEER 6 trials, 6,480 patients with T2D at high CV risk received placebo or semaglutide (once-weekly subcutaneously up to 1.0 mg, or once-daily orally up to 14 mg). NLRs were calculated from complete blood counts at randomisation. Adjudicated outcomes included 3-point major adverse CV events (MACE: composite of CV death, non-fatal myocardial infarction [MI] or non-fatal stroke; primary outcome), expanded MACE, CV death and all-cause death (secondary outcomes). Patient characteristics and CV outcomes were analysed according to baseline NLR tertiles using pooled trial data. Estimation of hazard ratios (HRs) for all outcomes across NLR tertiles used a Cox proportional hazards model. A Cox spline regression with continuous NLR as covariate adjusted for treatment was used to predict the event rate of first MACE at 2 years.
Results
Overall, baseline NLR was recorded in 6,364 patients. Mean baseline NLRs were 1.5, 2.2 and 3.6 in the low, middle and high tertiles, respectively. Patients in the high NLR tertile were older (66.6 years), more likely to be male (70.0%), had longer duration of diabetes (15.3 years), higher body weight (93.3 kg), lower diastolic blood pressure (75.5 mmHg) and estimated glomerular filtration rate (70.4 mL/min/1.73m2) vs those in the lower NLR tertiles (all p<0.0001). Higher NLR was associated with an increased risk of MACE (HR [95% confidence interval (CI)]: 1.37 [1.05; 1.80; p=0.02] and 1.86 [1.45; 2.41; p<0.0001] for the middle and high tertiles, respectively, vs the low tertile). The high NLR tertile was also associated with a 74% increased risk of expanded MACE and twofold risk for CV death and all-cause death vs the low NLR tertile (Figure 1). Spline regression indicated that NLR values >5 increased the risk of first MACE substantially (Figure 2). Further analysis of NLR and MACE by tertiles showed a more pronounced association in patients without prior MI and/or stroke (HR [95% CI]: 1.64 [1.07; 2.56]; p=0.03 and 2.09 [1.38; 3.21]; p=0.0006 in the middle and high tertiles, respectively, vs the low tertile).
Conclusion
Baseline NLR predicts MACE, CV death and all-cause death in patients with T2D and high CV risk. NLR is readily accessible from routinely obtained and inexpensive blood counts; it could offer a convenient, clinically useful inflammatory biomarker for CV risk prediction in this population.

Abstract
Abstract
Background
Patients (pts) with hyperlipidaemia and established cerebrovascular disease (CeVD) are at an increased risk of future strokes or other cardiovascular events.[1] In ischaemic stroke survivors, statins and inhibitors of proprotein convertase subtilisin-kexin type 9 (PCSK9) reduce recurrent cardiovascular events including stroke.[2–4] With guidelines increasingly advocating lower LDL-C goals, add-on lipid lowering therapies to statins may be needed. Inclisiran, a first-in-class small interfering RNA (siRNA) targeting PCSK9 messenger RNA, when added to maximally tolerated statin therapy, may provide further LDL-C lowering with a convenient, infrequent dosing schedule in pts with established CeVD.
Purpose
To assess efficacy and safety of inclisiran in pts with established CeVD.
Methods
Pts with HeFH, ASCVD or its risk equivalents from ORION-9 (NCT03397121]), ORION-10 (NCT03399370), and ORION-11 (NCT03400800) were randomised 1:1 to receive inclisiran sodium 300 mg (equivalent to 284 mg inclisiran) or placebo (pbo) at Days 1, 90 and 6-monthly thereafter to Day 540. This post hoc analysis included pts with established CeVD (ischaemic stroke, and/or carotid artery stenosis by angiography or ultrasound >70%, and/or prior percutaneous or surgical carotid artery revascularisation). Percentage LDL-C change from baseline to Day 510 and corresponding time-averaged percentage change from baseline after Day 90 to Day 540 were evaluated. Safety was assessed over 540 days.
Results
Of 202 pts with established CeVD, 110 and 92 received inclisiran and pbo, respectively. At baseline, 90.0% (99/110) of pts in inclisiran and 84.8% (78/92) in pbo group reported prior ischaemic stroke(s); others had carotid artery stenosis and/or carotid revascularisation (Table 1). Mean (95% CI) pbo-corrected LDL-C percentage change from baseline at Day 510 with inclisiran was −55.2% (−64.5 to −45.9); corresponding time-averaged change from baseline after Day 90 to Day 540 was −55.2% (−62.4 to −47.9) (P<0.0001 for each; Table 2). Treatment-emergent adverse event (TEAE) and treatment-emergent serious adverse event (TESAE) were more frequent in the inclisiran vs pbo group but were consistent with the overall pooled (N=3655) population of the combined trials. Clinically relevant TEAEs at the injection site were reported more frequently with inclisiran (3.6% [4/110]) vs pbo (0% [0/92]), but none were severe. Percentage of pts with clinically relevant laboratory measurements was low and similar between treatment groups and consistent with the overall pooled population (Table 2).
Conclusions
In pts with established CeVD, a twice-yearly dosing with inclisiran (after the initial and 3-month doses) provided sustained additional LDL-C reduction of ∼55%. A modest excess of mild/moderate TEAEs at the injection site were reported with inclisiran. The cardiovascular benefits of inclisiran among patients with established CeVD are being evaluated in ongoing trials.

Abstract
Abstract
Background
Approximately 25% of patients (pts) with atherosclerotic cardiovascular disease (ASCVD) have polyvascular disease (PVD), which involves ≥2 coronary, cerebrovascular, and peripheral artery beds. PVD is an independent predictor of major adverse cardiovascular (CV) events (MACE) and death.[1,2] Agents that inhibit proprotein convertase subtilisin-kexin type 9 (PCSK9) resulted in reduced low-density lipoprotein cholesterol (LDL-C) concentration and MACE incidence in pts with PVD.[3,4] Inclisiran is a small interfering RNA (siRNA) agent targeting PCSK9 messenger RNA that provided effective and sustained reduction in LDL-C concentration and was well tolerated.[5]
Purpose
To describe the effect inclisiran versus placebo (pbo) in pts with and without PVD.
Methods
This was a post hoc analysis from the ORION-9 (NCT03397121), ORION-10 (NCT03399370) and ORION-11 (NCT03400800) trials. Pts with heterozygous familial hypercholesterolaemia, ASCVD or risk equivalents were randomised 1:1 to receive 300 mg inclisiran sodium (equivalent to 284 mg inclisiran) or pbo at baseline, Day 90, and 6-monthly thereafter. LDL-C percentage change from baseline to Day 510 and corresponding time-averaged change from Day 90 and to Day 540 were evaluated by presence or absence of PVD (intention-to-treat population). Safety was assessed over 540 days (safety population).
Results
Of 3454 pts, 470 (13.6%) had PVD and 2984 (86.4%) did not. Baseline characteristics were generally balanced between treatment arms in both groups (Table 1). A greater proportion of pts with vs without PVD had CV risk factors at baseline. Mean LDL-C concentration at baseline was lower in pts with vs without PVD (Table 1). Mean (95% CI) pbo-corrected LDL-C percentage change from baseline to Day 510 with inclisiran was −48.9 (−55.6 to −42.2) in pts with PVD and −51.5 (−53.9 to −49.1) in pts without PVD (Table 2). Proportions of pts with treatment-emergent adverse events (TEAE) and treatment-emergent serious adverse events (TESAE) were similar between treatment arms irrespective of PVD status although reported TESAEs were numerically greater in both treatment arms for pts with PVD (Table 2). Clinically relevant TEAEs at the injection site were reported more frequently with inclisiran vs pbo in both groups but all were mild or moderate (Table 2). Proportions of pts with clinically relevant laboratory measurements were low and similar between treatment arms for both groups (Table 2).
Conclusions
Twice-yearly dosing with inclisiran (after the initial and 3-month doses) provided effective and sustained LDL-C lowering in pts, irrespective of their PVD status, with a safety profile similar to pbo, except for a modest excess of mainly mild TEAEs at the injection site. Notably, TESAEs were reported more frequently in pts with PVD, which was likely due to their more advanced disease. Since pts with PVD are at high risk of CV events, intensive LDL-C lowering may be beneficial to reduce this risk.

Abstract
Abstract
Background
In DECLARE-TIMI 58, the sodium glucose co-transporter 2 inhibitor (SGLT2i) dapagliflozin reduced the risk of the composite of cardiovascular (CV) death or hospitalization for heart failure (HHF) in a broad range of patients with type 2 diabetes mellitus (T2DM). SGLT2i are known to have diuretic and anti-hypertensive effects. However, whether concomitant CV drugs influence the efficacy and safety of dapagliflozin in these populations is less well known.
Purpose
We examined whether dapagliflozin consistently reduced the risk of CV outcomes and whether the safety of dapagliflozin was similar with or without the concurrent use of various CV drugs.
Methods
DECLARE–TIMI 58 was a randomized trial of dapagliflozin versus placebo in patients with T2DM and either atherosclerotic cardiovascular disease (ASCVD) or multiple risk factors for CV disease followed for a median of 4.2 years. We stratified patients by the use of CV drugs at baseline commonly used for heart failure: angiotensin-converting-enzyme inhibitors or angiotensin-receptor blockers (ACEi/ARB), beta-blockers, diuretics, and mineralocorticoid receptor antagonists (MRA). Efficacy outcomes of interest were the composite of CV death/HHF and HHF alone. We used the Cox proportional-hazard model for these analyses.
Results
Of 17,160 patients, 13,950 (81%) used ACEi/ARB, 9,030 (53%) used beta-blockers, 6,967 (41%) used diuretics, and 762 (4%) used MRA at baseline. All were balanced by randomized treatment groups. Patients using CV drugs at baseline had a greater prevalence of atherosclerotic risk factors and established CV disease than those without. Dapagliflozin consistently reduced the risk of CV death/HHF regardless of the use of CV medications (Figure). For HHF alone, similar results were seen with no significant interactions for any of the classes. There were no significant treatment interactions by the concomitant use of any of CV drugs for adverse events including symptoms of volume depletion or acute kidney injury.
Conclusions
In this analysis from the DECLARE–TIMI 58 trial, dapagliflozin consistently reduced the risk of CV death/HHF and HHF alone irrespective of the concurrent use of various CV drugs without any treatment interaction for key safety events.

Abstract
Abstract
Background
PCSK9 inhibitors and statins both lower LDL-C by increasing LDL-receptor (LDLR) function. PCSK9 inhibitors lower Lp(a) by 20–30%, whereas statins do not lower Lp(a). The mechanism by which PCSK9 inhibitors lower Lp(a) is unclear. We assessed the role of the LDLR in Lp(a) reductions produced by inclisiran, an siRNA which prevents hepatic synthesis of PCSK9.
Methods
ORION-1 was a phase 2 trial of inclisiran in subjects at high ASCVD risk with elevated LDL-C on optimized statin therapy. Subjects received one dose of inclisiran (200, 300, or 500 mg) or two doses at days 1 and 90 (100, 200, or 300 mg). We assessed the correlations between % change in Lp(a) and LDL-C at Day 180 for the inclisiran groups using Spearman correlation coefficients. We additionally assessed the correlation between % change in Lp(a) and absolute change in LDL-C as a proxy for LDLR expression. Lp(a) was measured using an isoform-independent assay and LDL-C with β-quantification.
Results
ORION-1 included 501 subjects; mean age 63; 65% male; 73% on statins. Median baseline Lp(a) was 37.0 nmol/l (IQR: 11.5–142.0 nmol/l), median LDL-C was 117.0 (IQR: 92.5–149.5 mg/dL). Inclisiran dose-dependently lowered Lp(a) by 14% to 26%. Overall, there was a significant but weak correlation between % change in Lp(a) LDL-C (Spearman coefficient 0.35, p<0.001). This correlation appeared to be stronger at higher inclisiran doses and with repeat dosing (table), as well as in statin-users versus non-users (Spearman coefficient 0.37 vs. 0.21). The correlation between % Lp(a) change and absolute LDL-C change was weaker (0.27, p<0.001).
Correlation coefficients LDL-C – Lp(a) Single-dose groups Two-dose groups Inclisiran overall 200 mg (n=60) 300 mg (n=60) 500 mg (n=60) 100 mg (n=59) 200 mg (n=60) 300 mg (n=59) Lp(a) ∼ % change LDL-C 0.22 0.26 0.22 0.29 0.47 0.51 0.35 Lp(a) ∼ absolute change LDL-C 0.35 0.12 0.04 0.22 0.45 0.24 0.27 Lp(a) ∼ % change LDL-C - Statin users 0.16 0.28 0.28 0.31 0.45 0.55 0.37 Lp(a) ∼ % change LDL-C - Non statin users 0.80 -0.08 0.09 0.10 0.63 0.09 0.21
Conclusion
The dose-dependent correlation between % changes in LDL-C and Lp(a) suggests that the LDLR may be partially responsible for Lp(a) reductions produced by inclisiran. The numerically stronger correlation in statin-users supports the idea that LDL-C may compete with Lp(a) for LDLR binding especially at low LDL-C levels.

Abstract
Abstract
Background
Among patients with acute coronary syndrome (ACS) who do not have diabetes, incident diabetes is common and associated with an adverse prognosis. Some data suggest that high density lipoprotein (HDL) has favourable effects on beta cell function and that cholesteryl ester transfer protein (CETP) inhibitors reduce incident type 2 diabetes in conjunction with increased HDL cholesterol (HDL-C) concentration. Dalcetrapib is a CETP inhibitor under ongoing evaluation as a potential cardiovascular therapy.
Purpose
We compared the effect of treatment with dalcetrapib or placebo on incident diabetes in patients with recent acute coronary syndrome (ACS).
Methods
In the dal-OUTCOMES trial, 15,871 patients were randomly assigned to treatment with dalcetrapib 600 mg or placebo daily, beginning 4–12 weeks after ACS. Absence of diabetes at baseline was based upon medical history, no use of diabetes medication, haemoglobin A1c <6.5%, and plasma glucose level <7 mmol/L (if measured under fasting conditions) or <11.1 mmol/L (if measured under non-fasting conditions). Among these patients, incident diabetes after randomization was defined by any diabetes-related adverse event, use of a diabetes medication, HbA1c ≥6.5%, or two measurements of plasma glucose ≥7 mmol/L (fasting) or ≥11.1 mmol/L (non-fasting). The association of incident diabetes with baseline and on-treatment HDL-C was determined.
Results
At baseline, 10621 patients (67% of the trial cohort) did not have diabetes and formed the analysis cohort. Over median follow-up of 31 months, incident diabetes was identified in 392 of 5314 patients (7.4%) assigned to dalcetrapib and 505 of 5307 (9.5%) assigned to placebo (odds ratio [OR] 0.76; 95% confidence interval [CI] 0.66–0.87; P<0.001). This corresponds to an absolute reduction in incident diabetes of 2.1%, and a need to treat 47 patients (for 31 months) to prevent 1 case of diabetes. Kaplan-Meier estimates of the cumulative incidence of diabetes are shown in the Figure. Across both treatment groups, incident diabetes was inversely associated with baseline HDL-C (OR 0.98 for 1 mg/dL increase in baseline HDL-C; 95% CI 0.97–0.98, P<0.001). In the dalcetrapib group, there was a further inverse association of incident diabetes with the change in HDL-C on assigned treatment (OR 0.98 for 1 mg/dL increase in HDL-C from baseline; 95% CI 0.97–0.99, P=0.002). Dalcetrapib was safe and generally well-tolerated in the trial.
Conclusions
In patients with recent ACS who do not have diabetes at baseline, incident diabetes is common. Dalcetrapib treatment reduced the relative risk of incident diabetes by 24% and the absolute risk by 2.1% over a median of 31 months. The reduction in incident diabetes with dalcetrapib was associated with increased HDL-C on treatment.

Abstract
Abstract
Background
Glucose lowering drugs or strategies (GLDS) have varied effects on major adverse cardiovascular events (MACE) and heart failure (HF) in cardiovascular outcomes trials. Mechanisms driving cardiovascular risk reduction remain elusive.
Methods
We searched MEDLINE, PubMed, and meeting abstracts up to 11/21/2018 for large GLDS cardiovascular outcome trials (CVOTs) in patients with or at risk for type 2 diabetes. Primary endpoints of MACE and HF were evaluated with random effects risk ratios (RR) and explored by baseline CVD subgroups and meta-regression by weight change across treatment arms.
Results
In 27 GLDS CVOTs, a total 207,820 patients, median age 63 years, 64% male, 64% CVD and 11% with prior HF were studied over a mean 3.8 years with 20,118 (10%) patients having MACE and 7,212 (4%) a HF event. Compared with standard care, GLDS overall lowered MACE (RR 0.92, P<0.ehz745.01171) but not HF (RR 1.01, P=0.91). Across GLDS, the magnitude and directionality varied modestly for MACE RR (P-int=0.07) but markedly for HF (P-int<0.ehz745.01171). Meta-regression showed a change in HF RR by 6% (95% CI 3%-9%) per 1 kg weight gain/loss between treatment arms (P=0.0006; Figure). In 9 trials of GLDS that achieved marked weight loss (lifestyle, GLP1 agonists, SGLT2 inhibitors), MACE benefit was confined to patients with baseline CVD (RR 0.89 [0.84–0.95] versus without (RR 1.02 [0.91–1.15]; P-int=0.01) with consistent HF effect (RR 0.80 [0.72–0.88] vs RR 0.76 [0.56–1.03]; P-int=0.74).
Heart Failure Risk and Changes in Weight
Conclusion
HF outcomes were improved with GLDS that lower weight. Among diabetes GLDS that lower weight, there was a robust risk reduction in atherothrombotic and heart failure events, with the MACE benefit confined to patients with established CVD.

Abstract
Abstract
Background/Introduction
Bempedoic acid (BA), an oral, first-in-class, ATP-citrate lyase inhibitor, lowers low-density lipoprotein cholesterol (LDL-C) in patients who do not achieve sufficient lipid lowering with guideline-recommended first-line therapies.
Purpose
We evaluated the safety profile of BA in phase 3 trials.
Methods
Data were pooled from 4 randomised, double-blind, placebo-controlled studies that enrolled patients with hyperlipidaemia who were receiving stable lipid-lowering therapy (LLT; maximally tolerated statins +/− nonstatin therapies) and required additional LDL-C lowering. Patients were randomised (2:1) to BA 180 mg or placebo daily for 12 to 52 weeks.
Results
Median exposure for 3621 patients (2424 BA, 1197 placebo) was 363 days. Background LLT included a statin +/− other LLT (83.8%), nonstatin LLT alone (9.4%), or none (6.8%). Adverse event (AE) and serious AE rates were similar between groups (Table). The most common AEs in the BA and placebo groups were nasopharyngitis (7.4% vs 8.9%), myalgia (4.9% vs 5.3%), and urinary tract infection (4.5% vs 5.5%). Rates of new-onset/worsening diabetes were 4.0% for BA and 5.6% for placebo. No AEs leading to discontinuation differed by ≥0.5% between treatments. All fatal AEs were judged by the investigator as unrelated to treatment. A trend was observed for a lower 3-component major adverse cardiac event rate with BA vs placebo (hazard ratio, 0.85; 95% confidence interval: 0.53 to 1.37). Changes in uric acid, creatinine, and haemoglobin were apparent at week 4, stable over time, and reversible after stopping BA.

Abstract
Abstract
Background
Renal dysfunction including both reduced estimated glomerular filtration rate (eGFR) and the presence of albuminuria have each been shown to predict cardiovascular (CV) outcomes. Sodium glucose co-transporter 2 inhibitors (SGLT2i), which promote glucose excretion in the kidneys, reduce CV events and hospitalizations for heart failure (HHF) in patients with type 2 diabetes mellitus (T2DM).
Purpose
To analyze the CV efficacy of dapagliflozin according to baseline renal function and albuminuria status in DECLARE-TIMI 58.
Methods
The DECLARE-TIMI 58 trial compared dapagliflozin vs. placebo in 17,160 patients with T2DM and a creatinine clearance >60 ml/min/1.73m2 at enrollment. The dual primary endpoints were CV death/HHF and MACE (MI, stroke, CV death). We categorized patients according baseline eGFR [<60 vs. ≥60 ml/min/1.73m2 according to the CKD-EPI formula] and urinary albumin:creatinine ratio (UACR) [<30 vs. ≥30 mg/g]. Cox regression models with interaction testing were applied. The Gail-Simon test was used to test for interaction of the absolute risk differences.
Results
In total, 5198 (30.3%) patients had albuminuria (UACR 30–300: n=4029; UACR >300: n=1169) and 1265 (7.4%) had an eGFR <60 ml/min/1.73m2. Accordingly, 10958 (63.9%) patients had no manifestation of CKD, 5367 (31.3%) had either an eGFR <60 ml/min/1.73m2 or albuminuria, and 548 (3.2%) patients had both manifestations. Patients with more abnormal markers had higher event rates for CV death/HHF (KM event rates at 4 years of 3.9%, 8.3%, 17.4%) and MACE (7.5%, 11.7%, and 18.9%) for no, 1, or 2 markers of CKD, respectively. The relative risk reductions for CV death/HHF and MACE were generally consistent across the subgroups (both P-interaction >0.29), though numerically greatest (42%) in patients with reduced eGFR and albuminuria. However, the absolute risk difference increased substantially in patients with greater kidney damage (absolute risk difference of CV death/HHF: −0.5%, −1.0%, and −8.3%, respectively; P-INT for ARD 0.002; Figure). See figure for MACE and component outcomes.
Conclusions
Patients with baseline renal disease had higher rates of adverse CV outcomes. Dapagliflozin reduced events with generally consistent relative risk, but reduced the absolute risk of CVD/HHF by the greatest amount in patients with kidney disease evidenced by both reduced eGFR and albuminuria.

P317A novel role of SGLT2 inhibitors to increase circulating proangiogenic progenitor cells in patients with type 2 diabetes and cardiovascular disease: A sub-study of the EMPA-HEART CardioLink-6 Trial.

Abstract
Abstract
Background
SGLT2 inhibitors (SGLT2i) have been demonstrated to reduce major adverse cardiovascular events and mortality in patients with type 2 diabetes (T2D) who are at high risk for cardiovascular disease (CVD). However, the mechanism(s) of the underlying benefit remain unclear. Since regenerative cell exhaustion resulting in impaired vascular homeostasis has been proposed as a key driver of CV events in T2D, we hypothesised that modulation of circulating vascular regenerative cell content by SGLT2i may be a novel basis of cardioprotection.
Purpose
To evaluate the effects of the SGLT2i, empagliflozin (EMPA), vs placebo on circulating vascular regenerative and pro-inflammatory cells in patients with T2D and CVD.
Methods
This was a biomarker sub-study of the EMPA-HEART Cardiolink-6 randomised trial of EMPA (10mg QD) vs placebo in patients with T2D and a history of coronary artery disease (prior myocardial infarction and/or coronary revascularisation). Blood samples (baseline N=48; study end N=26) underwent multiparametric progenitor cell analyses by flow cytometry. Circulating cells were assessed for aldehyde dehydrogenase (ALDH) activity, a self-protective enzyme highly expressed in several proangiogenic progenitor cell lineages, as well as cell surface co-expression of the primitive progenitor (CD34, CD133) or M1/M2 macrophage (CD80, CD163) markers.
Results
Individuals with increased inflammatory burden (ALDHhi granulocytes above the baseline median) were older (61±2 vs 67±2 years), more likely to be current or past smokers (21% vs 42%) and had reduced LV function, assessed by echocardiography. The placebo- and EMPA-assigned groups were equivalent at baseline with respect to the frequency and distribution of proangiogenic progenitor cells (ALDHhiSSClo), monocyte/macrophage (ALDHhiSSCmid) and inflammatory granulocyte (ALDHhiSSChi) precursors. Following 6-months of treatment with EMPA, there was a marked increase in the number of circulating primitive ALDHhiSSClo cells with CD133 (Placebo: −2.8±3.8%, EMPA: +8.6±2.5%, P<0.02) or CD133/CD34 (Placebo: 0.4±4.5%, EMPA: +13.3±3.8%, P<0.05) co-expression. Furthermore, EMPA treatment was associated with an increase in the frequency of circulating anti-inflammatory cells with M2 macrophage polarisation marked by CD163 (Placebo: −0.7±0.8%, EMPA = +3.9±1.3%, P<0.01) expression. Non-significant increases in circulating proangiogenic monocytes, and decreases in the frequency of circulating inflammatory granulocytes were also observed after EMPA treatment (vs placebo).
Conclusion
We provide the first evidence showing that SGLT2i treatment with EMPA alters the balance of key circulating vascular progenitor and inflammatory cells in patients with T2D and CVD. We suggest that SGLT2i may afford cardioprotection through a novel and previously unrecognised capacity to limit regenerative cell exhaustion in T2D.

Abstract
Abstract
Background
Patients with type 2 diabetes mellitus (T2DM) are at increased risk of developing heart failure (HF). Treatment with sodium-glucose cotransporter-2 (SGLT2) inhibitors reduces the risk of hospitalization for HF (HHF) in patients with T2DM.
Purpose
To develop and validate a practical, multivariable clinical risk score for HHF in patients with T2DM and assess whether this score can identify high-risk patients with T2DM who have the greatest reduction in risk for HHF with an SGLT2 inhibitor.
Methods
We developed a clinical risk score for centrally-adjudicated HHF using independent clinical risk indicators of HHF in 8212 patients with T2DM in the placebo arm of SAVOR-TIMI 53. Candidate variables were assessed using multivariable Cox regression and independent clinical risk indicators achieving statistical significance of p<0.001 were included in the risk score and given weights proportional to the regression coefficients. We externally validated the score in 8578 patients with T2DM in the placebo arm of DECLARE-TIMI 58. Discrimination was assessed using Harrell's c-index. The relative and absolute risk reductions in HHF with the SGLT2 inhibitor dapagliflozin were assessed by baseline HHF risk.
Results
The 5 independent clinical risk indicators were prior heart failure, atrial fibrillation, coronary artery disease, estimated glomerular filtration rate (eGFR), and urine albumin/creatinine ratio (UACR) (Figure, left). A simple integer-based scheme using these predictors identified a strong >16-fold gradient of HHF risk (p-trend <0.001) in both the derivation and validation cohorts, with c-indices of 0.81 and 0.78, respectively. Whereas relative risk reductions were similar across the risk score (25–34%), absolute risk reductions were greater in those at higher baseline risk (interaction p-value for absolute risk reduction <0.01), with high-risk (2 points) and very high-risk patients (≥3 points) having 1.5% and 2.7% absolute risk reductions in HHF at 4 years with dapagliflozin, translating into NNTs of only 65 and 36, respectively (Figure, right).
Conclusion(s)
Risk stratification using a novel clinical risk score for HHF in patients with T2DM identifies patients at higher risk for HHF who derive greater benefit from treatment with the SGLT2 inhibitor dapagliflozin.

P3753Does empagliflozin modulate the autonomic system among patients with type 2 diabetes and coronary artery disease? Insights from the Holter sub-study of the EMPA-Heart CardioLink-6 Randomised Trial. Eur Heart J 2019.

Abstract
Abstract
Introduction
The mechanism behind how empagliflozin, a sodium-glucose co-transporter 2 (SGLT2) inhibitor, reduces all-cause and cardiovascular mortality among patients with type 2 diabetes (T2DM) and coronary artery disease (CAD) is unknown. Autonomic tone, as reflected by changes in heart rate variability (HRV), is an established prognosticator in patients with CAD and/or heart failure.
Purpose
To assess if empagliflozin treatment changes HRV in subjects with T2DM and CAD.
Methods
In the double-blind EMPA-Heart trial, 97 subjects with T2DM and CAD were randomised to empagliflozin 10 mg/day or placebo for 6 months and underwent 24-hour Holter monitoring at baseline and 6 months. Using automated algorithms, time and frequency HRV domain measures were obtained (standard deviation of NN intervals (SDNN); SD of the average NN intervals for each 5-minute segment (SDANN); root mean square of successive RR interval differences (rMSSD); % interval differences of successive NN intervals >50 ms (pNN50); ratio of low to high frequency (LF/HF)). Changes of these HRV parameters were calculated over 6 months. Between-group differences in HRV parameters were compared using ANCOVA.
Results
Complete Holter data (baseline and 6-month) were available for 68% (n=66) of the cohort. The average heart rate (HR) at baseline/6 months was 69.5±9.8 bpm/72.8±8.1 bpm and 76±10.4 bpm/76.5±10.6 in the placebo group and empagliflozin group, respectively. Both groups had similar changes in average HR over 6 months. Key Holter data are summarised in the table. SDNN and SDANN were higher in the placebo vs. empagliflozin group at 6 months; no significant difference was noted for all other measures.
Empagliflozin 10 mg/day (n=33) Placebo (n=33) Adjusted difference between Empagliflozin and Placebo (ANCOVA) Baseline, Mean (SD) 6-month, Mean (SD) Baseline, Mean (SD) 6-month, Mean (SD) Mean, (95% CI) P-value SDNN (ms) 100.49 (43.74) 98.05 (38.86) 109.35 (30.02) 125.08 (43.83) −18.55 (−34.28, −2.82) 0.022 SDANN (ms) 86.84 (39.34) 83.76 (35.53) 94.70 (28.52) 118.28 (77.41) −20.24 (−37.27, −3.21) 0.021 rMSSD (ms) 27.00 (11.84) 27.22 (13.48) 28.00 (11.58) 27.17 (9.38) −1.23 (−6.02, 3.55) 0.608 pNN50 (%) 7.81 (7.59) 8.32 (9.51) 8.26 (7.8) 6.93 (5.35) 0.51 (−2.61, 3.62) 0.746 LF/HF ratio 1.63 (0.52) 1.65 (0.51) 1.53 (0.43) 1.83 (0.82) −0.08 (−0.38, 0.22) 0.602
Conclusions
Among subjects with T2DM and CAD, changes in HRV over 6 months were similar in the empagliflozin and placebo arms suggesting that the mortality benefit conferred by empagliflozin is not associated with positive modulation of autonomic tone.

Abstract
AIMS Increased body mass index (BMI) contributes to cardiovascular risk and may influence efficacy of therapeutic antibodies. We investigated the effect of baseline BMI on efficacy and safety of alirocumab, a PCSK9 monoclonal antibody. METHODS In a post-hoc analysis, data were pooled from 10 Phase 3 trials (n=4975) of alirocumab vs. placebo/ezetimibe controls. Alirocumab dose was 150mg every 2 weeks in two trials, and 75mg every 2 weeks with possible increase to 150mg at 12 weeks (based on Week 8 low-density lipoprotein cholesterol [LDL-C]) in eight trials. Efficacy/safety data were assessed in baseline BMI subgroups of≤25,>25 to 30,>30 to 35, and>35kg/m2. RESULTS Baseline LDL-C levels were lower among patients in the higher BMI subgroups. Significant LDL-C reductions from baseline were observed at Weeks 12 and 24 for alirocumab vs. controls, of similar magnitude regardless of baseline BMI (interaction P-value=0.7119). LDL-C<1.81mmol/L (<70mg/dL) was achieved at Week 24 by 69.8-76.4% of alirocumab-treated patients and 9.7-18.4% of control-treated patients, with no pattern by BMI. A greater proportion of patients in higher vs. lower BMI subgroups required alirocumab dose increase (P=0.0343); proportions were 22.5%, 24.9%, 31.7%, and 27.2% of patients across BMI subgroups of≤25,>25 to 30,>30 to 35, and>35kg/m2, respectively. Adverse event frequencies were similar regardless of BMI; injection-site reaction frequency was higher with alirocumab (5.1-8.2% across BMI categories) vs. controls (3.6-4.8%). CONCLUSIONS Alirocumab provided consistent LDL-C reductions, with similar safety findings across BMI subgroups.

Abstract
AIM To evaluate the safety of the proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor alirocumab according to diabetes mellitus status. METHODS Safety data from 14 trials (8-104-week durations) were analysed by treatment (alirocumab or placebo/ezetimibe control) and diabetes status (yes/no, defined by medical history). Adverse event data were assessed using descriptive statistics and Cox models. RESULTS Of the 5234 trial participants, 1554 (29.7%) had diabetes. Overall, treatment-emergent adverse events were similar in the alirocumab and control groups, except for more frequent local injection site reactions with alirocumab. Fewer people with diabetes experienced local injection site reactions [alirocumab, 3.5%, control, 2.9%; hazard ratio 1.24 (95% CI 0.68-2.25)] than those without diabetes [alirocumab, 7.5%; control, 4.9%; hazard ratio 1.51 (95% CI 1.13-2.01)]. Those with diabetes reported a greater number of serious adverse events (alirocumab, 19.4%; control, 19.7%) than those without diabetes (alirocumab, 14.5%; control, 13.5%). In people with diabetes, major adverse cardiac events occurred in 2.7% of alirocumab-treated people [control, 3.3%; hazard ratio 0.74 (95% CI 0.41-1.35)]; in those without diabetes, 1.8% of alirocumab-treated people had major adverse cardiac events [control, 1.7%; hazard ratio 0.95 (95% CI 0.56-1.62)]. Overall, no increase in HbA1c or fasting plasma glucose vs control treatment groups was observed, regardless of diabetes status. CONCLUSION This pooled analysis across 14 trials demonstrated similar safety for alirocumab vs control treatment, irrespective of diabetes status, except for more frequent local injection site reactions with alirocumab. People with diabetes reported fewer local injection site reactions than those without diabetes.

Abstract
Gastrointestinal (GI) adverse events (AEs) are the most frequently reported treatment-related AEs associated with glucagon-like peptide-1 receptor agonists (GLP-1RAs) in the treatment of type 2 diabetes mellitus. The GI safety of albiglutide, a once-weekly GLP-1RA, was assessed using data from five phase III studies. In a pooled analysis of four placebo-controlled trials, the most common GI AEs were diarrhoea (albiglutide, 14.5% vs. placebo, 11.5%) and nausea (albiglutide, 11.9% vs. placebo, 10.3%), with most patients experiencing 1-2 events. The majority were mild or moderate in intensity and their median duration was 3-4 days. Vomiting occurred in 4.9% of patients in the albiglutide vs. 2.6% in the placebo group. For both albiglutide and placebo, serious GI AEs (2.0% vs. 1.5%) and withdrawals attributable to GI AEs (1.7% vs. 1.5%) were low. In a 32-week trial of albiglutide 50 mg weekly versus liraglutide 1.8 mg daily, nausea occurred in 9.9% of patients in the albiglutide group vs. 29.2% in the liraglutide group. Vomiting occurred in 5.0% in the albiglutide vs. 9.3% in the liraglutide group. In conclusion, albiglutide has an acceptable GI tolerability profile, with nausea and vomiting rates slightly higher than those for placebo but lower than those for liraglutide.

Abstract
AIM To evaluate the long-term efficacy, safety and tolerability of dapagliflozin versus placebo added to usual care in patients with type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD). METHODS Data were pooled from two phase III studies (NCT01031680 and NCT01042977) in high-risk patients (N = 1887) with T2DM and CVD treated with dapagliflozin (10 mg/day) or placebo. Patients completing the double-blind treatment studies (24 weeks) entered one or two sequential double-blind, long-term (LT) extensions of 28 (LT1; n = 1649) and 52 (LT2; n = 568) weeks. RESULTS Baseline and CVD characteristics were similar in the two groups. Patients entering LT1 and LT2 on dapagliflozin maintained a greater mean reduction in glycated haemoglobin (HbA1c) versus placebo at 52 weeks [LT1, -0.58% (95% confidence interval -0.68, -0.49)] and 104 weeks [LT2, -0.35% (95% confidence interval -0.59, -0.12)]. Mean body weight and systolic blood pressure (SBP) reductions versus placebo were maintained in patients entering LT1 (52 weeks; -2.23 kg and -3.25 mmHg, respectively) and LT2 (104 weeks; -3.16 kg and -2.03 mmHg, respectively). Patients on dapagliflozin had a better three-item composite endpoint of clinical benefit (glycaemia, weight and SBP) compared with placebo at week 24 (LT1, 10.1% vs. 1.1%) and week 104 (LT2, 6.7% vs. 1.4%). Genital and urinary tract infections were more frequent with dapagliflozin than with placebo. Events of hypoglycaemia, renal impairment/failure and volume depletion were similar between groups. CONCLUSIONS The long-term efficacy of dapagliflozin to maintain reductions in HbA1c, SBP and body weight over 2 years, together with its tolerability profile, make dapagliflozin an appropriate option in high-risk patients with T2DM and CVD.

Effect of adding insulin degludec to treatment in patients with type 2 diabetes inadequately controlled with metformin and liraglutide: a double-blind randomized controlled trial (BEGIN: ADD TO GLP-1 Study). Diabetes Obes Metab 2016; 18:663-70. [PMID: 26990378 PMCID: PMC5074260 DOI: 10.1111/dom.12661] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/18/2015] [Revised: 03/07/2016] [Accepted: 03/11/2016] [Indexed: 01/19/2023]
Abstract
AIM To evaluate the efficacy and safety of adding insulin degludec (IDeg) to treatment in patients with type 2 diabetes receiving liraglutide and metformin and qualifying for treatment intensification because of inadequate glycaemic control. METHODS In this 26-week, double-blind trial, patients who still had inadequate glycaemic control after a 15-week run-in period with initiation and dose escalation of liraglutide to 1.8 mg in combination with metformin (≥1500 mg) were randomized to addition of once-daily IDeg ('IDeg add-on to liraglutide' arm; n = 174) or placebo ('placebo add-on to liraglutide' arm; n = 172), with dosing of both IDeg and placebo based on titration guidelines. RESULTS At 26 weeks, the mean change in glycated haemoglobin level was greater in the IDeg add-on to liraglutide arm (-1.04%) than in the placebo add-on to liraglutide arm (-0.16%; p < 0.0001). Similarly, the mean fasting plasma glucose reduction was greater, and self-measured plasma glucose values were lower at all eight time points, with IDeg add-on versus placebo add-on (both p < 0.0001). At 26 weeks, the IDeg dose was 51 U (0.54 U/kg). During the run-in period with liraglutide, body weight decreased by ∼3 kg in both groups. After 26 weeks, the mean change was +2.0 kg (IDeg add-on to liraglutide) and -1.3 kg (placebo add-on to liraglutide). Confirmed hypoglycaemia rates were low in both groups, although higher with IDeg than with placebo (0.57 vs. 0.12 episodes/patient-years of exposure; p = 0.0002). Nocturnal confirmed hypoglycaemia was infrequent in both groups, with no episodes of severe hypoglycaemia, and no marked differences in adverse events with either treatment approach. CONCLUSION The addition of liraglutide and IDeg to patients sub-optimally treated with metformin and liraglutide and requiring treatment intensification was found to be effective and well-tolerated.

LEADER 5: prevalence and cardiometabolic impact of obesity in cardiovascular high-risk patients with type 2 diabetes mellitus: baseline global data from the LEADER trial. Cardiovasc Diabetol 2016; 15:29. [PMID: 26864124 PMCID: PMC4750199 DOI: 10.1186/s12933-016-0341-5] [Citation(s) in RCA: 38] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/03/2015] [Accepted: 01/22/2016] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Epidemiological data on obesity are needed, particularly in patients with type 2 diabetes mellitus (T2DM) and high cardiovascular (CV) risk. We used the baseline data of liraglutide effect and action in diabetes: evaluation of CV outcome results-A long term Evaluation (LEADER) (a clinical trial to assess the CV safety of liraglutide) to investigate: (i) prevalence of overweight and obesity; (ii) relationship of the major cardiometabolic risk factors with anthropometric measures of adiposity [body mass index (BMI) and waist circumference (WC)]; and (iii) cardiometabolic treatment intensity in relation to BMI and WC. METHODS LEADER enrolled two distinct populations of high-risk patients with T2DM in 32 countries: (1) aged ≥50 years with prior CV disease; (2) aged ≥60 years with one or more CV risk factors. Associations of metabolic variables, demographic variables and treatment intensity with anthropometric measurements (BMI and WC) were explored using regression models (ClinicalTrials.gov identifier: NCT01179048). RESULTS Mean BMI was 32.5 ± 6.3 kg/m(2) and only 9.1 % had BMI <25 kg/m(2). The prevalence of healthy WC was also extremely low (6.4 % according to International Joint Interim Statement for the Harmonization of the Metabolic Syndrome criteria). Obesity was associated with being younger, female, previous smoker, Caucasian, American, with shorter diabetes duration, uncontrolled blood pressure (BP), antihypertensive agents, insulin plus oral antihyperglycaemic treatment, higher levels of triglycerides and lower levels of high-density lipoprotein cholesterol. CONCLUSIONS Overweight and obesity are prevalent in high CV risk patients with T2DM. BMI and WC are related to the major cardiometabolic risk factors. Furthermore, treatment intensity, such as insulin, statins or oral antihypertensive drugs, is higher in those who are overweight or obese; while BP and lipid control in these patients are remarkably suboptimal. LEADER confers a unique opportunity to explore the longitudinal effect of weight on CV risk factors and hard endpoints.

Frequency of cancer events with saxagliptin in the SAVOR-TIMI 53 trial. Diabetes Obes Metab 2016; 18:186-90. [PMID: 26443993 DOI: 10.1111/dom.12582] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/04/2015] [Revised: 09/22/2015] [Accepted: 09/27/2015] [Indexed: 12/14/2022]
Abstract
The Saxagliptin Assessment of Vascular Outcomes Recorded in Patients with Diabetes Mellitus (SAVOR)-Thrombolysis in Myocardial Infarction (TIMI) 53 trial randomized trial of 16,492 patients (placebo, n = 8212; saxagliptin, n = 8280) treated and followed for a median of 2.1 years afforded an opportunity to explore whether there was any association with cancer reported as a serious adverse event. At least one cancer event was reported by 688 patients (4.1%): 362 (4.3%) and 326 (3.8%) in the placebo and saxagliptin arms, respectively (p = 0.13). There were 59 (0.6%) deaths adjudicated as malignancy deaths with placebo and 53 (0.6%) with saxagliptin. Stratification by gender, age, race and ethnicity, diabetes duration, baseline glycated haemoglobin and pharmacotherapy did not show any clinically meaningful differences between the two study arms. The overall number of cancer events and malignancy-associated mortality rates were generally balanced between the placebo and saxagliptin groups, suggesting a null relationship with saxagliptin use over the median follow-up of 2.1 years. Multivariable modelling showed that male gender, dyslipidaemia and current smoking were independent predictors of cancer. These randomized data with adequate numbers of cancer cases are reassuring but limited, by the short follow-up in a trial not designed to test this hypothesis.

The effect of a dietary portfolio compared to a DASH-type diet on blood pressure. Nutr Metab Cardiovasc Dis 2015; 25:1132-1139. [PMID: 26552742 DOI: 10.1016/j.numecd.2015.08.006] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/21/2015] [Revised: 08/07/2015] [Accepted: 08/12/2015] [Indexed: 11/23/2022]
Abstract
BACKGROUND AND AIM Compared to a DASH-type diet, an intensively applied dietary portfolio reduced diastolic blood pressure at 24 weeks as a secondary outcome in a previous study. Due to the importance of strategies to reduce blood pressure, we performed an exploratory analysis pooling data from intensively and routinely applied portfolio treatments from the same study to assess the effect over time on systolic, diastolic and mean arterial pressure (MAP), and the relation to sodium (Na(+)), potassium (K(+)), and portfolio components. METHODS AND RESULTS 241 participants with hyperlipidemia, from four academic centers across Canada were randomized and completed either a DASH-type diet (control n = 82) or a dietary portfolio that included, soy protein, viscous fibers and nuts (n = 159) for 24 weeks. Fasting measures and 7-day food records were obtained at weeks 0, 12 and 24, with 24-h urines at weeks 0 and 24. The dietary portfolio reduced systolic, diastolic and mean arterial blood pressure compared to the control by 2.1 mm Hg (95% CI, 4.2 to -0.1 mm Hg) (p = 0.056), 1.8 mm Hg (CI, 3.2 to 0.4 mm Hg) (p = 0.013) and 1.9 mm Hg (CI, 3.4 to 0.4 mm Hg) (p = 0.015), respectively. Blood pressure reductions were small at 12 weeks and only reached significance at 24 weeks. Nuts, soy and viscous fiber all related negatively to change in mean arterial pressure (ρ = -0.15 to -0.17, p ≤ 0.016) as did urinary potassium (ρ = -0.25, p = 0.001), while the Na(+)/K(+) ratio was positively associated (ρ = 0.20, p = 0.010). CONCLUSIONS Consumption of a cholesterol-lowering dietary portfolio also decreased blood pressure by comparison with a healthy DASH-type diet. CLINICAL TRIAL REG. NO.: NCT00438425, clinicaltrials.gov.

Identification of educational needs in the management of overweight and obesity: results of an international survey of attitudes and practice. Clin Obes 2015; 5:245-55. [PMID: 26238414 DOI: 10.1111/cob.12109] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/09/2015] [Revised: 06/11/2015] [Accepted: 06/25/2015] [Indexed: 02/05/2023]
Abstract
Despite the availability of a growing range of interventions to assist control of body weight for people with excess weight or obesity, only a small proportion of people achieve their weight loss goals and are able to maintain body weight reductions in the long term. Negative attitudes and beliefs are often found among physicians and others involved in treating obesity and may adversely impact the effectiveness of management. In this international study, healthcare professionals were invited to complete an online survey of their attitudes and practice in the management of excess body weight. A total of 335 clinicians completed the survey of whom approximately half were based in Europe. A key finding from the survey is that, while participants are generally confident in their ability to manage overweight and obesity effectively, they also report that most of their patients are not successful in achieving their weight loss goals. At the same time, participants tended to overestimate the effectiveness of current medical management in maintaining reductions in body weight. Educational initiatives addressing the real-life effectiveness of different weight control interventions may help to close the gap between clinicians' perceptions and reality in the management of excess body weight.

Effect of fructose on markers of non-alcoholic fatty liver disease (NAFLD): a systematic review and meta-analysis of controlled feeding trials. Eur J Clin Nutr 2014; 68:416-23. [PMID: 24569542 PMCID: PMC3975811 DOI: 10.1038/ejcn.2014.8] [Citation(s) in RCA: 204] [Impact Index Per Article: 20.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2013] [Revised: 10/12/2013] [Accepted: 11/12/2013] [Indexed: 12/11/2022]
Abstract
BACKGROUND/OBJECTIVES In the absence of consistent clinical evidence, there are concerns that fructose contributes to non-alcoholic fatty liver disease (NAFLD). To determine the effect of fructose on markers of NAFLD, we conducted a systematic review and meta-analysis of controlled feeding trials. SUBJECTS/METHODS We searched MEDLINE, EMBASE, CINAHL and the Cochrane Library (through 3 September 2013). We included relevant trials that involved a follow-up of ≥ 7 days. Two reviewers independently extracted relevant data. Data were pooled by the generic inverse variance method using random effects models and expressed as standardized mean difference (SMD) for intrahepatocellular lipids (IHCL) and mean difference (MD) for alanine aminotransferase (ALT). Inter-study heterogeneity was assessed (Cochran Q statistic) and quantified (I(2) statistic). RESULTS Eligibility criteria were met by eight reports containing 13 trials in 260 healthy participants: seven isocaloric trials, in which fructose was exchanged isocalorically for other carbohydrates, and six hypercaloric trials, in which the diet was supplemented with excess energy (+21-35% energy) from high-dose fructose (+104-220 g/day). Although there was no effect of fructose in isocaloric trials, fructose in hypercaloric trials increased both IHCL (SMD=0.45 (95% confidence interval (CI): 0.18, 0.72)) and ALT (MD=4.94 U/l (95% CI: 0.03, 9.85)). LIMITATIONS Few trials were available for inclusion, most of which were small, short (≤ 4 weeks), and of poor quality. CONCLUSIONS Isocaloric exchange of fructose for other carbohydrates does not induce NAFLD changes in healthy participants. Fructose providing excess energy at extreme doses, however, does raise IHCL and ALT, an effect that may be more attributable to excess energy than fructose. Larger, longer and higher-quality trials of the effect of fructose on histopathological NAFLD changes are required.

Abstract
AIM To investigate the cardiometabolic risk (CMR) assessment and management patterns for individuals with and without type 2 diabetes mellitus (T2DM) in Canadian primary care practices. METHODS Between April 2011 and March 2012, physicians from 9 primary care teams and 88 traditional non-team practices completed a practice assessment on the management of 2461 patients >40 years old with no clinical evidence of cardiovascular disease and diagnosed with at least one of the following risk factor-T2DM, dyslipidaemia or hypertension. RESULTS There were 1304 individuals with T2DM and 1157 without. Pharmacotherapy to manage hyperglycaemia, dyslipidaemia and hypertension was widely prescribed. Fifty-eight percent of individuals with T2DM had a glycated haemoglobin (HbA1c) ≤7.0%. Amongst individuals with dyslipidaemia, median low-density lipoprotein cholesterol (LDL-C) was 1.8 mmol/l for those with T2DM and 2.8 mmol/l for those without. Amongst individuals with hypertension, 30% of those with T2DM achieved the <130/80 mmHg target, whereas 60% of those without met the <140/90 mmHg target. The composite glycaemic, LDL-C and blood pressure (BP) target outcome was achieved by 12% of individuals with T2DM. Only 17% of individuals with T2DM and 11% without were advised to increase their physical activity. Dietary modifications were recommended to 32 and 10% of those with and without T2DM, respectively. CONCLUSIONS Patients at elevated CMR were suboptimally managed in the primary care practices surveyed. There was low attainment of recommended therapeutic glycaemic, lipid and BP targets. Advice on healthy lifestyle changes was infrequently dispensed, representing a missed opportunity to educate patients on the long-term benefits of lifestyle modification.

Altering source or amount of dietary carbohydrate has acute and chronic effects on postprandial glucose and triglycerides in type 2 diabetes: Canadian trial of Carbohydrates in Diabetes (CCD). Nutr Metab Cardiovasc Dis 2013; 23:227-234. [PMID: 22397878 DOI: 10.1016/j.numecd.2011.12.011] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/18/2011] [Revised: 11/18/2011] [Accepted: 12/22/2011] [Indexed: 10/28/2022]
Abstract
BACKGROUND AND AIMS Nutrition recommendations for type 2 diabetes (T2DM) are partly guided by the postprandial responses elicited by diets varying in carbohydrate (CHO). We aimed to explore whether long-term changes in postprandial responses on low-glycemic-index (GI) or low-CHO diets were due to acute or chronic effects in T2DM. METHODS AND RESULTS Subjects with diet-alone-treated T2DM were randomly assigned to high-CHO/high-GI (H), high-CHO/low-GI (L), or low-CHO/high-monounsaturated-fat (M) diets for 12-months. At week-0 (Baseline) postprandial responses after H-meals (55% CHO, GI = 61) were measured from 0800 h to 1600 h. After 12 mo subjects were randomly assigned to H-meals or study diet meals (L, 57% CHO, GI = 50; M, 44% CHO, GI = 61). This yielded 5 groups: H diet with H-meals (HH, n = 34); L diet with H- (LH, n = 17) or L-meals (LL, n = 16); and M diet with H- (MH, n = 18) or M meals (MM, n = 19). Postprandial glucose fluctuations were lower in LL than all other groups (p < 0.001). Changes in postprandial-triglycerides differed among groups (p < 0.001). After 12 mo in HH and MM both fasting- and postprandial-triglycerides were similar to Baseline while in MH postprandial-triglycerides were significantly higher than at Baseline (p = 0.028). In LH, triglycerides were consistently (0.18-0.34 mmol/L) higher than Baseline throughout the day, while in LL the difference from Baseline varied across the day from 0.04 to 0.36 mmol/L (p < 0.001). CONCLUSION Low-GI and low-CHO diets have both acute and chronic effects on postprandial glucose and triglycerides in T2DM subjects. Thus, the composition of the acute test-meal and the habitual diet should be considered when interpreting the nutritional implications of different postprandial responses.

Abstract
AIMS To prospectively evaluate diabetes management in the primary care setting and explore factors related to guideline-recommended triple target achievement [blood pressure (BP) ≤ 130/80 mmHg, A1C ≤ 7% and low-density lipoprotein (LDL)-cholesterol < 2.5 mmol/l]. METHODS Baseline, 6 and 12 month data on clinical and laboratory parameters were measured in 3002 patients with type 2 diabetes enrolled as part of a prospective quality enhancement research initiative in Canada. A generalised estimating equation model was fitted to assess variables associated with triple target achievement. RESULTS At baseline, 54%, 53% and 64% of patients, respectively, had BP, A1C and LDL-cholesterol at target; all three goals were met by 19% of patients. The percentage of individuals achieving these targets significantly increased during the study [60%, 57%, 76% and 26%, respectively, at the final visit, p < 0.0001 except for A1C, p = 0.27]. A much smaller proportion of patients had adequate control during the entire study period [30%, 39%, 53% and 7%, respectively]. In multivariable analysis, women, patients younger than 65 years and patients of Afro-Canadian origin were less likely to achieve the triple target. DISCUSSION As part of a quality enhancement research initiative, we observed important improvements in the attainment of guidelines-recommended targets in patients with type 2 diabetes followed for a 12-month period in the primary care setting; however, many individuals still failed to achieve and especially maintain optimal goals for therapy, particularly the triple target. Results of the multivariable analysis reinforce the need to address barriers to improve diabetes care, particularly in more susceptible groups.

Abstract
AIM To assess the prevalence of persistent lipid abnormalities in statin-treated patients with diabetes with and without the metabolic syndrome. METHODS This was a cross-sectional study of 22,063 statin-treated outpatients consecutively recruited by clinicians in Canada and 11 European countries. Patient cardiovascular risk factors, risk level, lipid measurements and lipid-modifying medication regimens were recorded. RESULTS Of the 20,129 subjects who had documented diabetes and/or metabolic syndrome status, 41% had diabetes (of whom 86.8% also had the metabolic syndrome). Of those with diabetes, 48.1% were not at total cholesterol target compared with 58% of those without diabetes. Amongst those with diabetes, 41.6 and 41.3% of those with and without the metabolic syndrome, respectively, were not at their LDL cholesterol goal relative to 54.2% of those with metabolic syndrome and without diabetes, and 52% of those with neither condition. Twenty per cent of people with diabetes but without the metabolic syndrome were not at the optimal HDL cholesterol level compared with 9% of those with neither condition. Of people with diabetes and the metabolic syndrome, 49.9% were not at optimal triglyceride level relative to 13.5% of people with neither diabetes nor the metabolic syndrome. Simvastatin was the most commonly prescribed statin (>45%) and the most common statin potency was 20-40 mg/day (simvastatin equivalent). Approximately 14% of patients were taking ezetimibe alone or in combination with a statin. CONCLUSIONS Despite evidence supporting the benefits of lipid modification and international guideline recommendations, statin-treated patients with diabetes had a high prevalence of persistent lipid abnormalities. There is frequently room to optimize therapy through statin dose up-titration and/or addition of other lipid-modifying therapies.

Abstract
AIM This post hoc analysis compared the lipid-altering efficacy and safety of ezetimibe 10 mg plus statin (EZE/statin) vs. statin monotherapy in hypercholesterolaemic patients with and without diabetes. METHODS A pooled analysis of 27 previously published, randomized, double-blind, active- or placebo-controlled clinical trials comprising 21 794 adult patients with (n = 6541) and without (n = 15253) diabetes receiving EZE/statin or statin alone for 4-24 weeks evaluated percentage change from baseline in lipids and other parameters. Consistency of the treatment effect across the subgroups was tested using treatment × subgroup interaction. No multiplicity adjustments were made. RESULTS Treatment effects within both subgroups were generally consistent with the overall population. EZE/statin was more effective than statin alone in improving low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), triglycerides (TGs), non-HDL-C, apolipoprotein (apo) B and high-sensitivity C-reactive protein (hs-CRP) in the overall population and both subgroups. Patients with diabetes achieved significantly larger reductions in LDL-C, TC and non-HDL-C compared with non-diabetic patients. Incidences of adverse events or creatine kinase elevations were similar between groups. A small but significantly higher incidence of alanine aminotransferase or aspartate aminotransferase elevations was seen in patients receiving EZE/statin (0.6%) vs. statin monotherapy (0.3%) in the overall population. CONCLUSIONS Treatment with EZE/statin vs. statin monotherapy provided significantly larger reductions in LDL-C, TC, TG, non-HDL-C, apo B and hs-CRP and significantly greater increases in HDL-C, with a similar safety profile in patients with and without diabetes. Reductions in LDL-C, TC and non-HDL-C were larger in patients with diabetes than in patients without diabetes.

Abstract
AIMS/HYPOTHESIS Sugar has been suggested to promote obesity, diabetes and coronary heart disease (CHD), yet fruit, despite containing sugars, may also have a low glycaemic index (GI) and all fruits are generally recommended for good health. We therefore assessed the effect of fruit with special emphasis on low GI fruit intake in type 2 diabetes. METHODS This secondary analysis involved 152 type 2 diabetic participants treated with glucose-lowering agents who completed either 6 months of high fibre or low GI dietary advice, including fruit advice, in a parallel design. RESULTS Change in low GI fruit intake ranged from -3.1 to 2.7 servings/day. The increase in low GI fruit intake significantly predicted reductions in HbA(1c) (r = -0.206, p =0.011), systolic blood pressure (r = -0.183, p = 0.024) and CHD risk (r = -0.213, p = 0.008). Change in total fruit intake ranged from -3.7 to 3.2 servings/day and was not related to study outcomes. In a regression analysis including the eight major carbohydrate foods or classes of foods emphasised in the low GI diet, only low GI fruit and bread contributed independently and significantly to predicting change in HbA(1c). Furthermore, comparing the highest with the lowest quartile of low GI fruit intake, the percentage change in HbA(1c) was reduced by -0.5% HbA(1c) units (95% CI 0.2-0.8 HbA(1c) units, p < 0.001). CONCLUSIONS/INTERPRETATION Low GI fruit consumption as part of a low GI diet was associated with lower HbA(1c), blood pressure and CHD risk and supports a role for low GI fruit consumption in the management of type 2 diabetes. TRIAL REGISTRATION ClinicalTrials.gov NCT00438698.

Abstract
BACKGROUND Canadian and European treatment guidelines identify low-density lipoprotein cholesterol (LDL-C) as a primary treatment target for hypercholesterolaemia. OBJECTIVES This post hoc analysis compared ezetimibe 10 mg (ezetimibe) added to atorvastatin vs. doubling the atorvastatin dose on achievement of the 2009 Canadian Cardiovascular Society (CCS) and the 2007 Joint European Prevention Guidelines primary and optional secondary lipid targets and high-sensitivity C-reactive protein (hs-CRP) levels. METHODS After stabilisation on atorvastatin, hypercholesterolaemic patients at moderately high risk (MHR) for coronary heart disease (CHD) not at LDL-C < 2.6 mmol/l were randomised to atorvastatin 20 mg vs. doubling their atorvastatin dose to 40 mg; and patients at high risk (HR) for CHD not at LDL-C < 1.8 mmol/l were randomised to atorvastatin 40 mg plus ezetimibe vs. doubling their atorvastatin dose to 80 mg for 6 weeks. RESULTS When treated with atorvastatin plus ezetimibe, MHR and HR patients had greater attainment of LDL-C, most lipids and lipoproteins and/or hs-CRP targets compared with doubling their atorvastatin dose. More MHR and HR patients achieved dual targets of LDL-C and: Apolipoprotein (Apo) B, total cholesterol (total-C), total-C/high-density lipoprotein cholesterol (HDL-C), non-HDL-C, triglycerides, Apo B/Apo A-I or hs-CRP with ezetimibe + atorvastatin treatment compared with doubling their atorvastatin dose. CONCLUSIONS These results demonstrated greater achievement of single/dual treatment targets as set by Canadian and European treatment guidelines with ezetimibe added to atorvastatin 20 mg or 40 mg compared with doubling the atorvastatin dose to 40 mg or 80 mg in MHR and HR patients, respectively.

Abstract
AIM Type 2 diabetes mellitus (T2DM) and metabolic syndrome (MetS) are both associated with increased risk for atherosclerotic coronary heart disease (CHD). Thus, it is useful to know the relative efficacy of lipid-altering drugs in these patient populations. METHODS A double-blind, parallel group trial of adult patients with hypercholesterolaemia at high-CHD risk receiving atorvastatin 40 mg/day compared atorvastatin 40 mg plus ezetimibe 10 mg (ezetimibe) vs. doubling atorvastatin to 80 mg. This post hoc analysis reports lipid efficacy results in patients grouped by diagnosis of T2DM, MetS without T2DM or neither. Per cent change from baseline at week 6 was assessed for LDL-C, total cholesterol, HDL-C , non-HDL-C , Apo A-I, Apo B and triglycerides. Safety was monitored through clinical and laboratory adverse events (AEs). RESULTS Compared with doubling atorvastatin, atorvastatin plus ezetimibe resulted in greater reductions in LDL-C, triglycerides, Apo B, non-HDL-C, total cholesterol and lipid ratios in the T2DM, MetS and neither groups. Treatment effects were of similar magnitude across patient groups with both treatments, except triglycerides, which were slightly greater in the T2DM and MetS groups vs. neither group. Changes in HDL-C , Apo A-I and high sensitivity C-reactive protein (hs-CRP) were comparable for both treatments in all three groups. Safety and tolerability profiles were generally similar between treatments and across patient groups, as were the incidence of liver and muscle AEs. CONCLUSIONS Compared with doubling atorvastatin to 80 mg, addition of ezetimibe to atorvastatin 40 mg produced greater improvements in multiple lipid parameters in high-CHD risk patients with T2DM, MetS or neither, consistent with the significantly greater changes observed in the full study cohort (clinical trial # NCT00276484).

Abstract
The Diabetes Control and Complications Trial (DCCT) led to considerable improvements in the management of type 1 diabetes, with the wider adoption of intensive insulin therapy to reduce the risk of complications. However, a large gap between evidence and practice remains, as recently shown by the Pittsburgh Epidemiology of Diabetes Complications (EDC) study, in which 30-year rates of microvascular complications in the 'real world' EDC patients were twice that of DCCT patients who received intensive insulin therapy. This gap may be attributed to the many challenges that patients and practitioners face in the day-to-day management of the disease. These barriers include reaching glycaemic goals, overcoming the reality and fear of hypoglycaemia, and appropriate insulin therapy and dose adjustment. As practitioners, the question remains: how do we help patients with type 1 diabetes manage glycaemia while overcoming barriers? In this article, the Global Partnership for Effective Diabetes Management provides practical recommendations to help improve the care of patients with type 1 diabetes.

Viscosity of fiber preloads affects food intake in adolescents. Nutr Metab Cardiovasc Dis 2009; 19:498-503. [PMID: 19157816 DOI: 10.1016/j.numecd.2008.09.006] [Citation(s) in RCA: 49] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/27/2008] [Revised: 09/11/2008] [Accepted: 09/16/2008] [Indexed: 12/21/2022]
Abstract
BACKGROUND AND AIMS Dietary fiber that develops viscosity in the gastrointestinal tract is capable of addressing various aspects of food intake control. The aim of this study was to assess subsequent food intake and appetite in relation to the level of viscosity following three liquid preloads each containing 5 g of either a high (novel viscous polysaccharide; NVP), medium (glucomannan; GLM), or low (cellulose; CE) viscosity fiber. METHODS AND RESULTS In this double-blind, randomized, controlled and crossover trial, 31 healthy weight adolescents (25 F:6 M; age 16.1+/-0.6 years; BMI 22.2+/-3.7 kg/m(2)) consumed one of the three preloads 90 min prior to an ad libitum pizza meal. Preloads were identical in taste, appearance, nutrient content and quantity of fiber, but different in their viscosities (10, 410, and 700 poise for CE, GLM, and NVP, respectively). Pizza intake was significantly lower (p=0.008) after consumption of the high-viscosity NVP (278+/-111 g) compared to the medium-viscosity GLM (313+/-123 g) and low-viscosity CE (316+/-138 g) preloads, with no difference between the GLM and CE preloads. Appetite scores, physical symptoms and 24-h intake did not differ among treatment groups. CONCLUSION A highly viscous NVP preload leads to reduced subsequent food intake, in terms of both gram weight and calories, in healthy weight adolescents. This study provides preliminary evidence of an independent contribution of viscosity on food intake and may form a basis for further studies on factors influencing food intake in adolescents.
