Abstract
AIM The CAROLINA trial established non-inferiority of linagliptin versus glimepiride for major adverse cardiovascular events in patients with relatively early type 2 diabetes at increased cardiovascular risk. In pre-specified and post-hoc analyses, we investigated treatment effects on total hypoglycaemic burden in CAROLINA. MATERIALS AND METHODS Patients were randomized and treated with 5 mg linagliptin (n = 3014) or 1-4 mg glimepiride (n = 3000) once daily added to standard care. Hypoglycaemia captured from investigator-reported adverse events was analysed with Poisson and negative binomial regressions for the first and total (first plus recurrent) events, respectively. The influence of insulin initiation and glycated haemoglobin (HbA1c) change on the treatment effect for hypoglycaemia was also explored. RESULTS Over 6.3 years median follow-up, average HbA1c over time did not differ between linagliptin versus glimepiride (weighted mean difference [95% confidence interval]: 0.00%, [-0.05, 0.05]), nor did insulin initiation (18.6% vs. 19.2% of patients, respectively), whereas body weight was lower with linagliptin (-1.54 kg, [-1.80, -1.28]). Hypoglycaemia frequency was lower with linagliptin across all hypoglycaemia categories, including severe episodes. Rate ratios (95% confidence interval) for first and total events for investigator-reported hypoglycaemia were 0.21 (0.19-0.24) and 0.12 (0.10-0.14), respectively, with 8.7 first and 60.8 total estimated events prevented/100 patient-years with linagliptin versus glimepiride. These differences occurred during night-time and daytime, and in subgroup analyses of total events. Treatment differences in hypoglycaemia were neither impacted by HbA1c changes nor insulin initiation. CONCLUSIONS Across the severity spectrum, linagliptin substantially reduced the hypoglycaemic burden versus glimepiride in patients with relatively early type 2 diabetes at increased cardiovascular risk.

Abstract
BACKGROUND A recent 3-year post-marketing surveillance (PMS) study reaffirmed the safety and effectiveness of linagliptin in linagliptin-naïve Japanese patients with type 2 diabetes (T2D). We present further analyses from this study by body mass index (BMI). RESEARCH DESIGN AND METHODS Safety and effectiveness were assessed across BMI subgroups (<25, 25 to <30, and ≥30 kg/m2). RESULTS Data were available for 876, 566, and 201 patients in the BMI subgroups, respectively. Incidence of adverse drug reactions [ADR] with linagliptin was 11.42%, 11.31%, 10.45%, respectively. The most common ADR of special interest was hepatic disorders (n [%]: 6 [0.68], 7 [1.24] and 3 [1.49], respectively). Additional use of glucose-lowering drugs (GLDs) increased with BMI (15.0%, 19.1%, 24.4% of patients; P < 0.001). In the overall population, a sustained decrease in HbA1c was observed in all BMI subgroups. In patients receiving linagliptin with no additional GLDs, changes in HbA1c were -0.58%±0.04, -0.62%±0.04, and -0.77%±0.11. CONCLUSIONS In this study of linagliptin in Japanese patients with T2D, across BMI subgroups no new safety concerns were observed. The proportion of patients with additional GLD use increased with baseline BMI. Decreases in HbA1c were observed in all subgroups, including in patients with no additional GLD use.

Abstract
AIMS The sodium-glucose co-transporter 2 inhibitor empagliflozin reduced the total burden of cardiovascular, mortality, and all-cause hospitalization events, including first and recurrent events, in EMPA-REG OUTCOME participants with type 2 diabetes (T2D) and established atherosclerotic cardiovascular disease (ASCVD). We investigated the effect of empagliflozin on the total burden of cardiovascular and hospitalization events in Asian participants. MATERIALS AND METHODS Participants were randomized to empagliflozin 10 mg, 25 mg or placebo plus standard of care. The primary and key secondary outcomes were the composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke and the primary outcome plus hospitalization for unstable angina, respectively. The effect of pooled empagliflozin versus placebo on total (first plus recurrent) cardiovascular and hospitalization events was analysed using a negative binomial model that preserves randomization and accounts for within-patient correlation of multiple events. We analysed Asian versus non-Asian EMPA-REG OUTCOME population subgroups post hoc. RESULTS Among 1517 Asian participants, empagliflozin reduced the relative risk of total events of the primary outcome by 39% versus placebo [rate ratio (95% confidence interval): 0.61 (0.43, 0.89)], the key secondary outcome by 33% [0.67 (0.48, 0.93)], the composite of cardiovascular death (excluding fatal stroke) and hospitalization for heart failure by 43% [0.57 (0.33, 0.996)], and all-cause hospitalization by 21% [0.79 (0.65, 0.97)]. The effects of empagliflozin were consistent between Asian and non-Asian populations (treatment-by-subgroup interaction p > .05). CONCLUSIONS Empagliflozin reduced the total burden of cardiovascular and hospitalization events in Asian and non-Asian EMPA-REG OUTCOME participants with T2D and established ASCVD, consistent with the overall trial population.

Abstract
Formation of reactive oxygen species has been linked to the development of diabetes complications. Treatment with metformin has been associated with a lower risk of developing diabetes complications, including when used in combination with insulin. Metformin inhibits Complex 1 in isolated mitochondria and thereby decreases the formation of reactive oxygen species. Thus, we post-hoc investigated the effect of metformin in combination with different insulin regimens on RNA and DNA oxidation in individuals with type 2 diabetes. Four hundred and fifteen individuals with type 2 diabetes were randomized (1:1) to blinded treatment with metformin (1,000 mg twice daily) versus placebo and to (1:1:1) open-label biphasic insulin, basal-bolus insulin, or basal insulin therapy in a 2 × 3 factorial design. RNA and DNA oxidation were determined at baseline and after 18 months measured as urinary excretions of 8-oxo-7,8-dihydroguanosine (8-oxoGuo) and 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxodG), respectively. Urinary excretion of 8-oxoGuo changed by +7.1% (95% CI: 0.5% to 14.0%, P = 0.03) following metformin versus placebo, whereas changes in 8-oxodG were comparable between intervention groups. Biphasic insulin decreased urinary excretion of 8-oxoGuo (within-group: -9.6% (95% CI: -14.4% to -4.4%)) more than basal-bolus insulin (within-group: 5.2% (95% CI: -0.5% to 11.2%)), P = 0.0002 between groups, and basal insulin (within-group: 3.7% (95% CI: -2.0% to 9.7%)), P = 0.0007 between groups. Urinary excretion of 8-oxodG decreased more in the biphasic insulin group (within-group: -9.9% (95% CI: -14.4% to -5.2%)) than basal-bolus insulin (within group effect: -1.2% (95% CI: -6.1% to 3.9%)), P = 0.01 between groups, whereas no difference was observed compared with basal insulin. In conclusion, eighteen months of metformin treatment in addition to different insulin regimens increased RNA oxidation, but not DNA oxidation. Biphasic insulin decreased both RNA and DNA oxidation compared with other insulin regimens.

Abstract
AIM To examine the association between changes in lipids and markers of haemoconcentration (haematocrit and serum albumin) with empagliflozin, a sodium-glucose co-transporter-2 inhibitor, in patients with type 2 diabetes (T2D) using pooled data from four phase 3 randomized trials. MATERIALS AND METHODS Patients with T2D received placebo (n = 825), empagliflozin 10 mg (n = 830) or 25 mg (n = 822) for 24 weeks. In post hoc mediation analyses, we assessed total changes in LDL-cholesterol, HDL-cholesterol, triglycerides, apolipoprotein (Apo) B, and Apo A-I, and changes in these variables associated with, and independent of, changes in haematocrit and serum albumin at week 24 using ANCOVA models. RESULTS Empagliflozin versus placebo increased serum LDL-cholesterol, HDL-cholesterol, and Apo A-I, decreased triglycerides (empagliflozin 10 mg only), and (non-significantly) increased Apo B. Empagliflozin modestly increased haematocrit and serum albumin. In mediation analyses, haematocrit changes (increases) with empagliflozin were associated with significant changes (increases) in all lipid variables, including Apo B. Except for triglycerides (non-significant), similar lipid variable associations were observed with serum albumin changes. Haematocrit- and serum albumin-independent changes in lipids with empagliflozin were significant for HDL-cholesterol (increases), mostly significant for triglycerides (decreases), and less so for other lipid fractions. CONCLUSION Haematocrit and serum albumin increases were associated with increases in lipid fractions with empagliflozin. Empagliflozin-associated changes in serum lipids, particularly LDL-cholesterol increases, may be partly attributable to haemoconcentration resulting from increased urinary volume and subsequent volume contraction.

Abstract
UNLABELLED Some studies indicate potential beneficial effects of metformin on body composition and bone. This trial compared metformin + insulin vs placebo + insulin. Metformin treatment had a small but positive effect on bone quality in the peripheral skeleton, reduced weight gain, and resulted in a more beneficial body composition compared with placebo in insulin-treated patients with type 2 diabetes. INTRODUCTION Glucose-lowering medications affect body composition. We assessed the long-term effects of metformin compared with placebo on whole body bone and body composition measures in patients with type 2 diabetes mellitus. METHODS This was a sub-study of the Copenhagen Insulin and Metformin Therapy trial, which was a double-blinded randomized placebo-controlled trial assessing 18-month treatment with metformin compared with placebo, in combination with different insulin regimens in patients with type 2 diabetes mellitus (T2DM). The sub-study evaluates the effects on bone mineral content (BMC), density (BMD), and body composition from whole body dual-energy X-ray absorptiometry (DXA) scans which were assessed at baseline and after 18 months. RESULTS Metformin had a small, but positive, (p < 0.05) effect on subtotal, appendicular, and legs BMC and BMD compared with placebo. After adjustment for sex, age, vitamin D, smoking, BMI, T2DM duration, HbA1c, and insulin dose, the effects on appendicular BMC and BMD persisted (p < 0.05 for both). The changes in appendicular BMC and BMD corresponded approximately to a 0.7% and 0.5% increase in the metformin group and 0.4% and 0.4% decrease in the placebo group, respectively. These effects were mostly driven by an increase in BMC and BMD in the legs and a loss of BMC and BMD in the arms. During 18 months, all participants increased in weight, fat mass (FM), FM%, and lean mass (LM), but decreased in LM%. The metformin group increased less in weight (subtotal weight (weight-head) - 2.4 [- 3.5, - 1.4] kg, p value < 0.001) and FM (- 1.5 [- 2.3, - 0.8] kg, p value < 0.001) and decreased less in LM% (0.6 [0.2, 1.1] %, p value < 0.001) compared with the placebo group. CONCLUSION Metformin treatment had a small positive effect on BMC and BMD in the peripheral skeleton and reduced weight gain compared with placebo in insulin-treated patients with T2DM.

Abstract
BACKGROUND The cardiovascular and kidney safety of glucose-lowering drugs is a key concern in type 2 diabetes (T2D). We evaluated cardiorenal outcomes with glucose-lowering drugs in Asian patients, who comprise over half of T2D cases globally. RESEARCH DESIGN AND METHODS A rapid evidence assessment was conducted for phase III or IV, double-blind, randomized clinical trials of glucose-lowering drugs reporting cardiovascular or kidney outcomes for Asian T2D patients (Embase, Medline, Cochrane Library databases: 1 January 2008-14 June 2020). RESULTS Fifty-four publications reported exploratory data for Asians from 18 trials of dipeptidyl peptidase-4 (DPP-4) inhibitors, sodium-glucose co-transporter-2 (SGLT2) inhibitors, glucagon-like peptide-1 (GLP-1) receptor agonists, and insulin analogs. SGLT2 inhibitors and several GLP-1 receptor agonists were associated with reduced cardiovascular risk in Asian T2D patients, while DPP-4 inhibitors exhibited cardiovascular safety. SGLT2 inhibitors also appeared to reduce renal risk; however, kidney outcomes were lacking for DPP-4 inhibitors other than linagliptin and GLP-1 receptor agonists in Asian patients. Insulin data were inconclusive as the only trial conducted used different types of insulin as both treatment and comparator. CONCLUSIONS Cardiorenal outcomes with glucose-lowering drugs in Asian T2D patients were similar to outcomes in the overall multinational cohorts of these trials. DPP-4 inhibitors appear to demonstrate cardiovascular safety in Asians, while SGLT2 inhibitors and some GLP-1 receptor agonists may reduce cardiorenal and cardiovascular risk, respectively.

Abstract
BACKGROUND Patients with type 2 diabetes and atherosclerotic cardiovascular disease are at high clinical risk. We assessed the effect of the sodium-glucose co-transporter-2 inhibitor, empagliflozin, on total cardiovascular events and admissions to hospital in the EMPA-REG OUTCOME trial. METHODS The EMPA-REG OUTCOME trial was a randomised, double-blind, non-inferiority trial of patients (aged ≥18 years) with type 2 diabetes and atherosclerotic cardiovascular disease done between August, 2010, and April, 2015. Participants were randomly assigned (1:1:1) to empagliflozin 10 mg or 25 mg, or placebo. The primary outcome was major adverse cardiovascular events: a composite of cardiovascular death, non-fatal stroke, or non-fatal myocardial infarction. As prespecified, the effects of pooled empagliflozin versus placebo were assessed on total (first plus recurrent) events of major adverse cardiovascular events, fatal or non-fatal myocardial infarction, fatal or non-fatal stroke, and admission to hospital for heart failure. We also did post-hoc analyses on additional cardiovascular and admission to hospital outcomes. We used statistical models that preserve randomisation and account for correlation of recurrent events, including negative binomial regression, as prespecified for the primary analyses. The EMPA-REG OUTCOME trial is registered with ClinicalTrials.gov, NCT01131676, and is closed to accrual. FINDINGS In the EMPA-REG OUTCOME trial, 7020 patients were randomly assigned and treated with empagliflozin 10 mg (n=2345), empagliflozin 25 mg (n=2342), or placebo (n=2333) and followed up for a median of 3·2 years (IQR 2·2 to 3·6) in the pooled empagliflozin group and 3·1 years (2·2 to 3·5) in the placebo group. Analysing total (first plus recurrent) events, empagliflozin versus placebo reduced the risk of major adverse cardiovascular events (rate ratio [RR] 0·78 [95% CI 0·67 to 0·91]; p=0·0020; 12·88 [95% CI 3·74 to 22·02] events prevented per 1000 patient-years); fatal or non-fatal myocardial infarction (0·79 [0·62 to 0·998]; p=0·049; 4·97 [-0·68 to 10·61] events prevented per 1000 patient-years); the composite of fatal or non-fatal myocardial infarction, or coronary revascularisation (0·80 [0·67 to 0·95]; p=0·012; 11·65 [1·25 to 22·05] events prevented per 1000 patient-years); admission to hospital for heart failure (0·58 [0·42 to 0·81]; p=0·0012; 9·67 [3·07 to 16·28] events prevented per 1000 patient-years); and all-cause admission to hospital (0·83 [0·76 to 0·91]; p<0·0001; 50·41 [26·20 to 74·63] events prevented per 1000 patient-years). For outcomes significantly reduced with empagliflozin, risk reductions were numerically larger for total events than for first events. Total fatal or non-fatal stroke was not significantly different between treatment groups (RR 1·10 [95% CI 0·82 to 1·49]; p=0·52). INTERPRETATION Empagliflozin reduced the total burden of cardiovascular complications and all-cause admission to hospital in patients with type 2 diabetes and atherosclerotic cardiovascular disease.

Abstract
AIMS To investigate measures of carotid intima-media thickness (IMT) and conventional cardiovascular (CV) risk factors as predictors of future carotid IMT, and the prediction of CV events during follow-up based on measures of carotid IMT. METHODS Observational longitudinal study including 230 persons with type 2 diabetes (T2D). RESULTS Mean age at follow-up was 66.7 (SD 8.5) years, 30.5% were women and mean body mass index (BMI) was 31.8 (4.4) kg/m2. Carotid IMT was measured at baseline, after 18 months of intervention in the Copenhagen Insulin and Metformin Therapy (CIMT) trial and after a mean follow-up of 6.4 (1.0) years. Baseline carotid IMT, carotid IMT after 18 months' intervention, and CV risk factors (age, sex and baseline systolic blood pressure) gave the best prediction of carotid IMT (root mean-squared error of prediction of 0.106 and 95% prediction error probability interval of -0.160, 0.204). CONCLUSIONS Measures of carotid IMT combined with CV risk factors at baseline predicts attained carotid IMT better than measures of carotid IMT or CV risk factors alone. Carotid IMT did not predict CV events, and the present results do not support the use of carotid IMT as a predictor of CV events in persons with T2D.

Abstract
Background Metformin has been shown to have both neuroprotective and neurodegenerative effects. The aim of this study was to investigate the effect of metformin in combination with insulin on cardiovascular autonomic neuropathy (CAN) and distal peripheral neuropathy (DPN) in individuals with type 2 diabetes (T2DM). Methods The study is a sub-study of the CIMT trial, a randomized placebo-controlled trial with a 2 × 3 factorial design, where 412 patients with T2DM were randomized to 18 months of metformin or placebo in addition to open-labelled insulin. Outcomes were measures of CAN: Changes in heart rate response to deep breathing (beat-to-beat), orthostatic blood pressure (OBP) and heart rate and vibration detection threshold (VDT) as a marker DPN. Serum levels of vitamin B12 and methyl malonic acid (MMA) were analysed. Results After 18 months early drop in OBP (30 s after standing) was increased in the metformin group compared to placebo: systolic blood pressure drop increased by 3.4 mmHg (95% CI 0.6; 6.2, p = 0.02) and diastolic blood pressure drop increased by 1.3 mmHg (95% CI 0.3; 2.6, p = 0.045) compared to placebo. Beat-to-beat variation decreased in the metformin group by 1.1 beats per minute (95% CI − 2.4; 0.2, p = 0.10). Metformin treatment did not affect VDT group difference − 0.33 V (95% CI − 1.99; 1.33, p = 0.39) or other outcomes. Changes in B12, MMA and HbA1c did not confound the associations. Conclusions Eighteen months of metformin treatment in combination with insulin compared with insulin alone increased early drop in OBP indicating an adverse effect of metformin on CAN independent of vitamin B12, MMA HbA1c. Trial registration The protocol was approved by the Regional Committee on Biomedical Research Ethics (H–D-2007-112), the Danish Medicines Agency and registered with ClinicalTrials.gov (NCT00657943).

Abstract
Preclinical studies have shown a potential osteoanabolic effect of metformin but human studies of how metformin affects bone turnover are few. A post hoc sub-study analysis of an 18-month multicenter, placebo-controlled, double-blinded trial in type 2 diabetes mellitus (T2DM), randomizing participants to metformin versus placebo both in combination with different insulin analogue regimens (Metformin + Insulin vs. Placebo + Insulin). Patients were not treatment naive at baseline, 83% had received metformin, 69% had received insulin, 57.5% had received the combination of metformin and insulin before entering the study. Bone formation and resorption were assessed by measuring, N-terminal propeptide of type I procollagen (P1NP) and C-terminal telopeptide of type I collagen (CTX) at baseline and end of study. The influence of gender, age, smoking, body mass index (BMI), T2DM duration, glycosylated hemoglobin A1c (HbA1c), c-reactive protein (CRP) and insulin dosage was also included in the analyses. The levels of bone formation marker P1NP and bone resorption marker CTX increased significantly in both groups during the trial. P1NP increased less in the Metformin + Insulin compared to the placebo + insulin group (p = 0.001) (between group difference change), while the increases in CTX levels (p = 0.11) were not different. CRP was inversely associated (p = 0.012) and insulin dosage (p = 0.011) was positively related with change in P1NP levels. BMI (p = 0.002) and HbA1C (p = 0.037) were inversely associated with change in CTX levels. During 18 months of treatment with metformin or placebo, both in combination with insulin, bone turnover increased in both groups. But the pattern was different as the bone formation marker (P1NP) increased less during Metformin + Insulin treatment, while change in bone resorption (CTX) was not significantly different between the two groups.

Abstract
Abstract
Background and aims
The EMPA-REG OUTCOME trial included patients with type 2 diabetes (T2D) and established atherosclerotic cardiovascular (CV) disease. Empagliflozin reduced the risk of 3-point major adverse CV events (MACE; composite of CV death, myocardial infarction [MI], or stroke) by 14%, CV death by 38% and hospitalisation for heart failure (HF) by 35% vs placebo in analyses of time to first event. We assessed the effect of empagliflozin on all-cause hospitalisation in post-hoc analyses of all (first and recurrent) events.
Materials and methods
Patients were randomised to receive empagliflozin 10 mg, empagliflozin 25 mg, or placebo in addition to standard of care. We assessed the effects of empagliflozin pooled vs placebo on first event of all-cause hospitalisation using Cox regression and all (first and recurrent) events of all-cause hospitalisation using a negative binomial model.
Results
A total of 7020 patients were treated (4687 empagliflozin; 2333 placebo, mean [SD] age 63 [9] years, 71% male, 47% with history of MI, 23% with history of stroke, 10% with HF). In this analysis, 1725/4687 (36.8%) empagliflozin patients and 925/2333 (39.6%) placebo patients experienced an event leading to hospitalisation. The adjusted hazard ratio (HR; 95% CI) vs placebo for first all-cause hospitalisation using the Cox regression model was 0.89 (0.82, 0.96; p=0.0033; Figure); In analyses of all (first and recurrent) hospitalisation events, there were 3168 events in the empagliflozin group and 1863 in the placebo group. The adjusted event rate ratio (95% CI) vs placebo was 0.83 (0.76, 0.91; p<0.0001; Figure).
Conclusion
In the EMPA-REG OUTCOME trial, risk reductions with empagliflozin were seen in both first and all hospitalisation events and were numerically more favourable in analyses of all events vs analyses of first events. These analyses expand on the favourable CV effects of empagliflozin by also showing a reduction in the total burden of hospitalisation events in patients with T2D and established CV disease.

Abstract
INTRODUCTION We report a randomized, double-blind, placebo-controlled, 4-week study to investigate the effect of empagliflozin on free fatty acids and blood ketone bodies in Japanese patients with type 2 diabetes mellitus. METHODS Patients (baseline mean [standard deviation] glycated hemoglobin 7.91% [0.80%]; body mass index 24.3 [3.2] kg/m2) were randomized to empagliflozin 10 mg (n = 20), empagliflozin 25 mg (n = 19), or placebo (n = 21) daily as monotherapy for 28 days. Meal tolerance tests (MTTs; breakfast, lunch, dinner) were performed on day - 1, day 1 (first day of treatment), and day 28. On day 1 and day 28, study drug was administered 1 h before breakfast. Free fatty acids and blood ketone bodies were measured before and 1, 2, and 3 h after each MTT, and the next morning (overnight fast). RESULTS Empagliflozin significantly reduced plasma glucose and insulin and reduced body weight vs. placebo. Empagliflozin increased free fatty acids and total ketones bodies at day 1 and day 28. At day 28, the adjusted mean (95% confidence interval) difference vs. placebo in the time-corrected area under curve over 24 h for total ketone bodies was 67.1 (12.3, 121.8) µmol·h/L·h (P = 0.017) with empagliflozin 10 mg and 178.1 (123.9, 232.2) µmol·h/L·h (P < 0.001) with empagliflozin 25 mg. Increases in ketones with empagliflozin vs. placebo peaked just before and declined after meals, with the highest peak before breakfast. Changes in total ketone bodies appeared to be associated with changes in plasma glucose, insulin, and free fatty acids. CONCLUSION Empagliflozin modestly increased free fatty acids and blood ketone bodies after a single dose and 28 days' treatment. Increases in ketones appeared to be related to the duration of fasting and were most pronounced before breakfast. Increases in ketones appeared to be associated with changes in well-known metabolic determinants of ketone production. TRIAL REGISTRATION ClinicalTrials.gov identifier, NCT01947855.

Abstract
Abstract
Background
In type 2 diabetes, the temporal proximity of an atherosclerotic cardiovascular (CV) event can impact prognosis, but whether timing influences sodium glucose co-transporter 2 inhibitor effects is unknown. We explored the association of time from last qualifying CV event before randomisation (myocardial infarction [MI], stroke, coronary artery disease or peripheral arterial disease) with CV outcomes and benefit of empagliflozin (EMPA) in EMPA-REG OUTCOME.
Methods
Patients (pts) were randomised to EMPA 10 mg, 25 mg or placebo and followed for 3.1 years (median). Risk of major adverse CV events (3P MACE: CV death, MI, stroke), CV death or hospitalisation for heart failure (HHF) were evaluated using Cox regression in subgroups of ≤1/>1 year since last qualifying CV event. Qualifying event stratification was possible in 6796 (97%) pts.
Results
In the overall population, N=6796 (4547 EMPA and 2249 placebo pts), median (Q1, Q3) time from last CV event was 3.8 (1.5–7.6) years. Overall, 1214 (EMPA 841; placebo 373) and 5582 (EMPA 3706; placebo 1876) pts had a last qualifying CV event ≤1 and >1 year, respectively. Pts with more recent events had similar risk for CV outcomes compared with pts >1 year from qualifying event (Figure). Moreover, the benefit of EMPA on CV outcomes was consistent between pts enrolled ≤1 or >1 year from the qualifying CV event (all p-interaction >0.05; Figure).
Conclusion
Although most pts had a qualifying CV event >1 year before randomisation in EMPA-REG OUTCOME, the benefits of EMPA appear to extend to pts with more recent CV events.

Abstract
UNLABELLED Some antihyperglycemic medications have been found to affect bone metabolism. We assessed the long-term effects of metformin compared with placebo on bone mineral density (BMD) and trabecular bone score (TBS) in patients with type 2 diabetes. Metformin had no significant effect on BMD in the spine and hip or TBS compared with a placebo. INTRODUCTION Patients with type 2 diabetes mellitus (T2DM) have an increased risk of fractures despite a high bone mass. Some antihyperglycemic medications have been found to affect bone metabolism. We assessed the long-term effects of metformin compared with placebo on bone mineral density (BMD) and trabecular bone score (TBS). METHODS This was a sub-study of a multicenter, randomized, 18-month placebo-controlled, double-blinded trial with metformin vs. placebo in combination with different insulin regimens (the Copenhagen Insulin and Metformin Therapy trial) in patients with T2DM. BMD in the spine and hip and TBS in the spine were assessed by dual-energy X-ray absorptiometry at baseline and after 18 months follow-up. RESULTS Four hundred seven patients were included in this sub-study. There were no between-group differences in BMD or TBS. From baseline to 18 months, TBS decreased significantly in both groups (metformin group, - 0.041 [- 0.055, - 0.027]; placebo group - 0.046 [- 0.058, - 0.034]; both p < 0.001). BMD in the spine and total hip did not change significantly from baseline to 18 months. After adjustments for gender, age, vitamin D, smoking, BMI, duration of T2DM, HbA1c, and insulin dose, the TBS between-group differences increased but remained non-significant. HbA1c was negatively associated with TBS (p = 0.009) as was longer duration of diabetes, with the femoral neck BMD (p = 0.003). Body mass index had a positive effect on the hip and femoral neck BMD (p < 0.001, p = 0.045, respectively). CONCLUSIONS Eighteen months of treatment with metformin had no significant effect on BMD in the spine and hip or TBS in patients with T2DM compared with a placebo. TBS decreased significantly in both groups. TRIAL REGISTRATION ClinicalTrials.gov (NCT00657943).

Abstract
INTRODUCTION Clinical trials conducted in patients with type 2 diabetes (T2DM) treated with glucose-lowering drugs and examining cardiovascular-related outcomes have yielded mixed results. In this work, we aimed to assess the relative treatment effects of empagliflozin versus sitagliptin and saxagliptin (dipeptidyl peptidase-4 (DPP-4) inhibitors) on cardiovascular-related outcomes in patients with T2DM. METHODS We conducted a systematic literature review to identify clinical trials assessing cardiovascular-related outcomes for sitagliptin-, saxagliptin-, and empagliflozin-treated patients with T2DM. A network meta-analysis of indirect treatment comparisons was conducted in a Bayesian framework. Hazard ratios (HR) and 95% credible intervals (CrI) were computed for six cardiovascular-related outcomes to estimate the relative efficacies of these agents. RESULTS Empagliflozin showed a statistically significant superiority over saxagliptin (HR 0.60; 95% CrI 0.46-0.80) and sitagliptin (HR 0.60; 95% CrI 0.46-0.79) to reduce the risk for cardiovascular-related mortality. For all-cause mortality, empagliflozin showed a statistically significant risk reduction compared to saxagliptin (HR 0.61; 95% CrI 0.49-0.76) and sitagliptin (HR 0.67; 95% CrI 0.54-0.83). A similar pattern was observed in the risk reduction for hospitalization due to heart failure, where empagliflozin was found to be statistically significantly superior to saxagliptin (HR 0.51; 95% CrI 0.37-0.70) and sitagliptin (HR 0.65; 95% CrI 0.47-0.90). Empagliflozin was not statistically significantly different to sitagliptin and saxagliptin with regard to the risk of a composite endpoint composed of death, stroke or myocardial infarction. CONCLUSION In this indirect comparison to the DPP-4 inhibitors saxagliptin and sitagliptin, empagliflozin significantly lowered the risk of cardiovascular-related mortality, all-cause mortality and hospitalizations due to heart failure.

Abstract
AIMS To analyse the effect of baseline glycated haemoglobin (HbA1c) on the reduction in HbA1c with empagliflozin compared with sitagliptin or glimepiride in patients with type 2 diabetes. MATERIALS AND METHODS Using regression analyses of individual patient data from two Phase III studies, we compared the change in HbA1c according to a unit change in baseline HbA1c (the slope) with empagliflozin 10 mg or 25 mg vs sitagliptin (monotherapy) after 24 weeks, and with empagliflozin 25 mg vs glimepiride (as add-on to metformin) after 52 weeks. RESULTS Steeper slopes of HbA1c decline were observed with empagliflozin 10 or 25 mg vs sitagliptin monotherapy at week 24. Regression analysis showed slopes of -0.59 (95% CI -0.70, -0.47), -0.49 (95% CI -0.62, -0.37) and -0.29 (95% CI -0.42, -0.15) for empagliflozin 10 mg, empagliflozin 25 mg and sitagliptin, respectively (P < .001 and P < .05 for empagliflozin 10 mg and empagliflozin 25 mg, respectively, vs sitagliptin). Similarly, a steeper slope of HbA1c decline was observed with empagliflozin 25 mg vs glimepiride as add-on to metformin at week 52. Regression analysis showed slopes of - 0.52 (95% CI -0.59, -0.44) and -0.32 (95% CI -0.39, -0.25) for empagliflozin 25 mg and glimepiride, respectively (P < .001 for empagliflozin 25 mg vs glimepiride). CONCLUSIONS Incremental reductions in HbA1c with increasing baseline HbA1c are greater with empagliflozin compared with sitagliptin or glimepiride in patients with type 2 diabetes.

Abstract
Sodium glucose cotransporter 2 (SGLT2) inhibitors reduce HbA1c, blood pressure, and weight in patients with type 2 diabetes. To investigate the effect of renal function on reductions in these parameters with the SGLT2 inhibitor empagliflozin, we assessed subgroups by baseline estimated glomerular filtration rate (eGFR; Modification of Diet in Renal Disease) in pooled data from five 24-week trials of 2286 patients with type 2 diabetes randomized to empagliflozin or placebo. Reductions in HbA1c with empagliflozin versus placebo significantly diminished with decreasing baseline eGFR. Reductions in systolic blood pressure (SBP) with empagliflozin were maintained in patients with lower eGFR. The mean placebo-corrected changes from baseline in systolic blood pressure at week 24 with empagliflozin were -3.2 (95% confidence interval -4.9,-1.5) mmHg, -4.0 (-5.4, -2.6) mmHg, -5.5 (-7.6, -3.4) mmHg, and -6.6 (-11.4, -1.8) mmHg in patients with an eGFR of 90 or more, 60 to 89, 30 to 59, and under 30 ml/min/1.73m2, respectively. Similar trends were observed for diastolic blood pressure. Weight loss with empagliflozin versus placebo tended to be attenuated in patients with a lower eGFR. Results were consistent in a 12-week ambulatory blood pressure monitoring trial in 823 patients with type 2 diabetes and hypertension. Thus, unlike HbA1c reductions, systolic blood pressure and weight reductions with empagliflozin are generally preserved in patients with chronic kidney disease.

Abstract
Inhibition of sodium glucose cotransporter 2 with empagliflozin results in caloric loss by increasing urinary glucose excretion and has a mild diuretic effect. Diuretic effects are usually associated with reflex-mediated increases in sympathetic tone, whereas caloric loss is associated with decreased sympathetic tone. In an open-label trial, muscle sympathetic nerve activity (MSNA) (burst frequency, burst incidence, and total MSNA) was assessed using microneurography performed off-treatment and on day 4 of treatment with empagliflozin 25 mg once daily in 22 metformin-treated patients with type II diabetes (mean [range] age 54 [40-65] years). Systolic and diastolic blood pressure (BP), heart rate, urine volume, and body weight were assessed before and on day 4 (BP, heart rate), day 5 (urine volume), or day 6 (body weight) of treatment with empagliflozin. After 4 days of treatment with empagliflozin, no significant changes in MSNA were apparent despite a numerical increase in urine volume, numerical reductions in BP, and significant weight loss. There were no clinically relevant changes in heart rate. Empagliflozin is not associated with clinically relevant reflex-mediated sympathetic activation in contrast to increases observed with diuretics in other studies. Our study suggests a novel mechanism through which sodium glucose cotransporter 2 inhibition affects human autonomic cardiovascular regulation.

Abstract
AIMS/HYPOTHESIS Sodium glucose cotransporter 2 (SGLT2) inhibition lowers HbA1c, systolic BP (SBP) and weight in patients with type 2 diabetes and reduces renal hyperfiltration associated with type 1 diabetes, suggesting decreased intraglomerular hypertension. As lowering HbA1c, SBP, weight and intraglomerular pressure is associated with anti-albuminuric effects in diabetes, we hypothesised that SGLT2 inhibition would reduce the urine albumin-to-creatinine ratio (UACR) to a clinically meaningful extent. METHODS We examined the effect of the SGLT2 inhibitor empagliflozin on UACR by pooling data from patients with type 2 diabetes and prevalent microalbuminuria (UACR = 30-300 mg/g; n = 636) or macroalbuminuria (UACR > 300 mg/g; n = 215) who participated in one of five phase III randomised clinical trials. Primary assessment was defined as percentage change in geometric mean UACR from baseline to week 24. RESULTS After controlling for clinical confounders including baseline log-transformed UACR, HbA1c, SBP and estimated GFR (according to the Modification of Diet in Renal Disease [MDRD] formula), treatment with empagliflozin significantly reduced UACR in patients with microalbuminuria (-32% vs placebo; p < 0.001) or macroalbuminuria (-41% vs placebo; p < 0.001). Intriguingly, in regression models, most of the UACR-lowering effect with empagliflozin was not explained by SGLT2 inhibition-related improvements in HbA1c, SBP or weight. CONCLUSIONS/INTERPRETATION In patients with type 2 diabetes and either micro- or macroalbuminuria, empagliflozin reduced UACR by a clinically meaningful amount. This effect was largely independent of the known metabolic or systemic haemodynamic effects of this drug class. Our results further support a direct renal effect of SGLT2 inhibitors. Prospective studies are needed to explore the potential of this intervention to alter the course of kidney disease in high-risk patients with diabetes.

Abstract
AIMS To determine the effects of empagliflozin on adiposity indices among patients with type 2 diabetes mellitus. METHODS Changes in weight, waist circumference, estimated total body fat, index of central obesity and visceral adiposity index were assessed using analysis of covariance and testing of treatment by strata for age, sex and baseline waist circumference in patients with type 2 diabetes mellitus randomized to blinded treatment with empagliflozin versus placebo in clinical trials of 12 weeks (cohort 1) or 24 weeks (cohort 2) duration. RESULTS This study comprised 3300 patients (cohort 1, N = 823; cohort 2, N = 2477). Empagliflozin reduced weight, waist circumference and adiposity indices versus placebo in both cohorts. Adjusted mean (95% confidence interval) change from baseline in empagliflozin versus placebo was -1.7 kg (-2.1 to -1.4 kg) and -1.9 kg (-2.1 to -1.7 kg) for body weight (p < 0.001); -1.3 cm (-1.8 to -0.7 cm) and -1.3 cm (-1.7 to -1.0 cm) for waist circumference (p < 0.001); -0.2% (-0.7% to 0.3%; p = 0.45) and -0.3% (-0.7% to 0.0%; p = 0.08) for estimated total body fat; -0.007 (-0.011 to -0.004) and -0.008 (-0.010 to -0.006) for index of central obesity (p < 0.001); and -0.3 (-0.5 to 0.0; p = 0.07) and -0.4 (-0.7 to -0.1; p = 0.003) for visceral adiposity index in cohorts 1 and 2, respectively. Adipose reductions were seen across most age, sex and waist circumference subgroups. CONCLUSION Empagliflozin significantly reduced weight and adiposity indices with the potential to improve cardiometabolic risk among patients with type 2 diabetes mellitus.

Abstract
OBJECTIVE To assess the effect of 3 insulin analogue regimens on change in carotid intima-media thickness (IMT) in patients with type 2 diabetes. DESIGN AND SETTING Investigator-initiated, randomised, placebo-controlled trial with a 2 × 3 factorial design, conducted at 8 hospitals in Denmark. PARTICIPANTS AND INTERVENTIONS Participants with type 2 diabetes (glycated haemoglobin (HbA1c) ≥ 7.5% (≥ 58 mmol/mol), body mass index >25 kg/m(2)) were, in addition to metformin versus placebo, randomised to 18 months open-label biphasic insulin aspart 1-3 times daily (n=137) versus insulin aspart 3 times daily in combination with insulin detemir once daily (n=138) versus insulin detemir alone once daily (n=137), aiming at HbA1c ≤ 7.0% (≤ 53 mmol/mol). OUTCOMES Primary outcome was change in mean carotid IMT (a marker of subclinical cardiovascular disease). HbA1c, insulin dose, weight, and hypoglycaemic and serious adverse events were other prespecified outcomes. RESULTS Carotid IMT change did not differ between groups (biphasic -0.009 mm (95% CI -0.022 to 0.004), aspart+detemir 0.000 mm (95% CI -0.013 to 0.013), detemir -0.012 mm (95% CI -0.025 to 0.000)). HbA1c was more reduced with biphasic (-1.0% (95% CI -1.2 to -0.8)) compared with the aspart+detemir (-0.4% (95% CI -0.6 to -0.3)) and detemir (-0.3% (95% CI -0.4 to -0.1)) groups (p<0.001). Weight gain was higher in the biphasic (3.3 kg (95% CI 2.7 to 4.0) and aspart+detemir (3.2 kg (95% CI 2.6 to 3.9)) compared with the detemir group (1.9 kg (95% CI 1.3 to 2.6)). Insulin dose was higher with detemir (1.6 IU/kg/day (95% CI 1.4 to 1.8)) compared with biphasic (1.0 IU/kg/day (95% CI 0.9 to 1.1)) and aspart+detemir (1.1 IU/kg/day (95% CI 1.0 to 1.3)) (p<0.001). Number of participants with severe hypoglycaemia and serious adverse events did not differ. CONCLUSIONS Carotid IMT change did not differ between 3 insulin regimens despite differences in HbA1c, weight gain and insulin doses. The trial only reached 46% of planned sample size and lack of power may therefore have affected our results. TRIAL REGISTRATION NUMBER NCT00657943.

Abstract
OBJECTIVE To assess the effect of metformin versus placebo both in combination with insulin analogue treatment on changes in carotid intima-media thickness (IMT) in patients with type 2 diabetes. DESIGN AND SETTING Investigator-initiated, randomised, placebo-controlled trial with a 2 × 3 factorial design conducted at eight hospitals in Denmark. PARTICIPANTS AND INTERVENTIONS 412 participants with type 2 diabetes (glycated haemoglobin (HbA1c) ≥ 7.5% (≥ 58 mmol/mol); body mass index >25 kg/m2) were in addition to open-labelled insulin treatment randomly assigned 1:1 to 18 months blinded metformin (1 g twice daily) versus placebo, aiming at an HbA1c ≤ 7.0% (≤ 53 mmol/mol). OUTCOMES The primary outcome was change in the mean carotid IMT (a marker of subclinical cardiovascular disease). HbA1c, insulin dose, weight and hypoglycaemic and serious adverse events were other prespecified outcomes. RESULTS Change in the mean carotid IMT did not differ significantly between the groups (between-group difference 0.012 mm (95% CI -0.003 to 0.026), p=0.11). HbA1c was more reduced in the metformin group (between-group difference -0.42% (95% CI -0.62% to -0.23%), p<0.001)), despite the significantly lower insulin dose at end of trial in the metformin group (1.04 IU/kg (95% CI 0.94 to 1.15)) compared with placebo (1.36 IU/kg (95% CI 1.23 to 1.51), p<0.001). The metformin group gained less weight (between-group difference -2.6 kg (95% CI -3.3 to -1.8), p<0.001). The groups did not differ with regard to number of patients with severe or non-severe hypoglycaemic or other serious adverse events, but the metformin group had more non-severe hypoglycaemic episodes (4347 vs 3161, p<0.001). CONCLUSIONS Metformin in combination with insulin did not reduce carotid IMT despite larger reduction in HbA1c, less weight gain, and smaller insulin dose compared with placebo plus insulin. However, the trial only reached 46% of the planned sample size and lack of power may therefore have affected our results. TRIAL REGISTRATION NUMBER NCT00657943; Results.

Abstract
The Cochrane Metabolic and Endocrine Disorders Group withdrew this review as of Issue 7, 2015 because of the involvement of one author (SS Lund) being employed in a pharmaceutical company. The authors of the review and the Cochrane Metabolic and Endocrine Disorders Group did not find that this was a breach of the rules of the Cochrane Collaboration at the time when it was published. However, after the publication of the review, the Cochrane Collaboration requested withdrawal of the review due to the employment of the author. A new protocol for a review to cover this topic will be published. This will have a new title and a markedly improved protocol fulfilling new and important developments and standards within the Cochrane Collaboration as well as an improved inclusion and search strategy making it necessary to embark on a completely new review project. The editorial group responsible for this previously published document have withdrawn it from publication.

Abstract
BACKGROUND This study evaluated the effect of empagliflozin on postprandial glucose (PPG) and 24-hour glucose variability in Japanese patients with type 2 diabetes mellitus (T2DM). METHODS Patients (N = 60; baseline mean [SD] HbA1c 7.91 [0.80]%; body mass index 24.3 [3.2] kg/m(2)) were randomized to receive empagliflozin 10 mg (n = 20), empagliflozin 25 mg (n = 19) or placebo (n = 21) once daily as monotherapy for 28 days. A meal tolerance test and continuous glucose monitoring (CGM) for 24 hours were performed at baseline and on days 1 and 28. The primary endpoint was change from baseline in area under the glucose concentration-time curve 3 hours after breakfast (AUC1-4h for PPG) at day 28. RESULTS Adjusted mean (95%) differences versus placebo in changes from baseline in AUC1-4h for PPG at day 1 were -97.1 (-126.5, -67.8) mg · h/dl with empagliflozin 10 mg and -91.6 (-120.4, -62.8) mg · h/dl with empagliflozin 25 mg (both p < 0.001 versus placebo) and at day 28 were -85.5 (-126.0, -45.0) mg · h/dl with empagliflozin 10 mg and -104.9 (-144.8, -65.0) mg · h/dl with empagliflozin 25 mg (both p < 0.001 versus placebo). Adjusted mean (95% CI) differences versus placebo in change from baseline in 24-hour mean glucose (CGM) at day 1 were -20.8 (-27.0, -14.7) mg/dl with empagliflozin 10 mg and -23.9 (-30.0, -17.9) mg/dl with empagliflozin 25 mg (both p < 0.001 versus placebo) and at day 28 were -24.5 (-35.4, -13.6) mg/dl with empagliflozin 10 mg and -31.7 (-42.5,-20.9) mg/dl with empagliflozin 25 mg (both p < 0.001 versus placebo). Changes from baseline in mean amplitude of glucose excursions (MAGE; CGM) were not significantly different with either empagliflozin dose versus placebo at either timepoint. Curves of mean glucose (CGM) did not change between baseline and day 1 or 28 with placebo, but shifted downward with empagliflozin. Percentage of time with glucose ≥70 to <180 mg/dl increased from 52.0% at baseline to 77.0% at day 28 with empagliflozin 10 mg and from 55.0% to 81.1% with empagliflozin 25 mg, without increasing time spent with hypoglycemia. CONCLUSION Empagliflozin for 28 days reduced PPG from the first day and improved daily blood glucose control in Japanese patients with T2DM. TRIAL REGISTRATION Clinicaltrials.gov NCT01947855.

Abstract
OBJECTIVE Studies have indicated a blood pressure (BP)-lowering effect of milk-derived peptides in non-diabetic individuals, but the cardiometabolic effects of such peptides in patients with type 2 diabetes (T2D) are not known. We investigated the effect of milk fermented with Lactobacillus helveticus on BP, glycaemic control and cardiovascular risk factors in T2D. DESIGN A randomised, double-blinded, prospective, placebo-controlled study. METHODS In one arm of a factorial study design, 41 patients with T2D were randomised to receive 300 ml milk fermented with L. helveticus (Cardi04 yogurt) (n=23) or 300 ml artificially acidified milk (placebo yogurt) (n=18) for 12 weeks. BPs were measured over 24-h, and blood samples were collected in the fasting state and during a meal test before and after the intervention. RESULTS Cardi04 yogurt did not reduce 24-h, daytime or nighttime systolic or diastolic BPs compared with placebo (P>0.05). Daytime and 24-h heart rate (HR) were significantly reduced in the group treated by Cardi04 yogurt compared with the placebo group (P<0.05 for both). There were no differences in HbA1c, plasma lipids, C-reactive protein, plasminogen activator inhibitor-1, tumour necrosis factor alpha, tissue-type plasminogen activator: Ag, and von Willebrand factor: Ag between the groups. The change in fasting blood glucose concentration differed significantly between the two groups with a larger increase in the placebo group (P<0.05). CONCLUSIONS Ingestion of milk fermented with L. helveticus compared with placebo for 12 weeks did not significantly reduce BP in patients with T2D. Our finding of lower HRs and fasting plasma glucose levels in T2D patients during ingestion of fermented milk needs further validation.

Abstract
BACKGROUND Patients with type 2 diabetes mellitus (T2D) have an increased risk of cardiovascular disease and mortality compared to the background population. Observational studies report an association between reduced blood glucose and reduced risk of both micro- and macrovascular complications in patients with T2D. Our previous systematic review of intensive glycaemic control versus conventional glycaemic control was based on 20 randomised clinical trials that randomised 29 ,986 participants with T2D. We now report our updated review. OBJECTIVES To assess the effects of targeted intensive glycaemic control compared with conventional glycaemic control in patients with T2D. SEARCH METHODS Trials were obtained from searches of The Cochrane Library, MEDLINE, EMBASE, Science Citation Index Expanded, LILACS, and CINAHL (all until December 2012). SELECTION CRITERIA We included randomised clinical trials that prespecified targets of intensive glycaemic control versus conventional glycaemic control targets in adults with T2D. DATA COLLECTION AND ANALYSIS Two authors independently assessed the risk of bias and extracted data. Dichotomous outcomes were assessed by risk ratios (RR) and 95% confidence intervals (CI). Health-related quality of life and costs of intervention were assessed with standardized mean differences (SMD) and 95% Cl. MAIN RESULTS Twenty-eight trials with 34,912 T2D participants randomised 18,717 participants to intensive glycaemic control versus 16,195 participants to conventional glycaemic control. Only two trials had low risk of bias on all risk of bias domains assessed. The duration of the intervention ranged from three days to 12.5 years. The number of participants in the included trials ranged from 20 to 11,140. There were no statistically significant differences between targeting intensive versus conventional glycaemic control for all-cause mortality (RR 1.00, 95% CI 0.92 to 1.08; 34,325 participants, 24 trials) or cardiovascular mortality (RR 1.06, 95% CI 0.94 to 1.21; 34,177 participants, 22 trials). Trial sequential analysis showed that a 10% relative risk reduction could be refuted for all-cause mortality. Targeting intensive glycaemic control did not show a statistically significant effect on the risks of macrovascular complications as a composite outcome in the random-effects model, but decreased the risks in the fixed-effect model (random RR 0.91, 95% CI 0.82 to 1.02; and fixed RR 0.93, 95% CI 0.87 to 0.99; P = 0.02; 32,846 participants, 14 trials). Targeting intensive versus conventional glycaemic control seemed to reduce the risks of non-fatal myocardial infarction (RR 0.87, 95% CI 0.77 to 0.98; P = 0.02; 30,417 participants, 14 trials), amputation of a lower extremity (RR 0.65, 95% CI 0.45 to 0.94; P = 0.02; 11,200 participants, 11 trials), as well as the risk of developing a composite outcome of microvascular diseases (RR 0.88, 95% CI 0.82 to 0.95; P = 0.0008; 25,927 participants, 6 trials), nephropathy (RR 0.75, 95% CI 0.59 to 0.95; P = 0.02; 28,096 participants, 11 trials), retinopathy (RR 0.79, 95% CI 0.68 to 0.92; P = 0.002; 10,300 participants, 9 trials), and the risk of retinal photocoagulation (RR 0.77, 95% CI 0.61 to 0.97; P = 0.03; 11,212 participants, 8 trials). No statistically significant effect of targeting intensive glucose control could be shown on non-fatal stroke, cardiac revascularization, or peripheral revascularization. Trial sequential analyses did not confirm a reduction of the risk of non-fatal myocardial infarction but confirmed a 10% relative risk reduction in favour of intensive glycaemic control on the composite outcome of microvascular diseases. For the remaining microvascular outcomes, trial sequential analyses could not establish firm evidence for a 10% relative risk reduction. Targeting intensive glycaemic control significantly increased the risk of mild hypoglycaemia, but substantial heterogeneity was present; severe hypoglycaemia (RR 2.18, 95% CI 1.53 to 3.11; 28,794 participants, 12 trials); and serious adverse events (RR 1.06, 95% CI 1.02 to 1.10; P = 0.007; 24,280 participants, 11 trials). Trial sequential analysis for a 10% relative risk increase showed firm evidence for mild hypoglycaemia and serious adverse events and a 30% relative risk increase for severe hypoglycaemia when targeting intensive versus conventional glycaemic control. Overall health-related quality of life, as well as the mental and the physical components of health-related quality of life did not show any statistical significant differences. AUTHORS' CONCLUSIONS Although we have been able to expand the number of participants by 16% in this update, we still find paucity of data on outcomes and the bias risk of the trials was mostly considered high. Targeting intensive glycaemic control compared with conventional glycaemic control did not show significant differences for all-cause mortality and cardiovascular mortality. Targeting intensive glycaemic control seemed to reduce the risk of microvascular complications, if we disregard the risks of bias, but increases the risk of hypoglycaemia and serious adverse events.

Abstract
AIM To examine preferences for oral medication attributes among participants with early and advanced type 2 diabetes mellitus (T2DM) in the UK using a discrete choice experiment (DCE). METHODS A web-based DCE was administered where participants indicated which medication they preferred from two different hypothetical oral anti-diabetic (OAD) medication profiles, each composed of differing levels of seven attributes (efficacy, hypoglycaemic events, weight change, gastrointestinal/nausea side effects, urinary tract infection and genital infection, blood pressure and cardiovascular risk) for 20 sets of pair-wise comparisons. A random effects multinomial logit regression model was used to estimate the preference weight (PW) for each of the attribute levels, and the relative importance (RI) of each attribute was calculated. Analyses were conducted for the overall sample and for medication and gender subgroups. RESULTS The final sample included 100 participants with a mean age of 62.9 (SD 11.1) years and comparable numbers of participants of each gender (51% male, 49% female). The majority of the participants were White-British (92%). The total PW and corresponding RI were highest for four of the seven attributes: hypoglycaemic events (PW = 1.98; RI = 24.7%), weight change (PW = 1.65; RI = 20.6%), gastrointestinal/nausea side effects (PW = 1.49; RI = 18.6%) and efficacy (PW = 1.44; RI = 18.0%). The RI values differed for some attributes across gender and number of current T2DM medication subgroups. CONCLUSION The results suggest that hypoglycaemia, weight change, gastrointestinal side effects and efficacy are of primary importance to patients in their OAD preferences in T2DM. These four attributes comprised over 80% of the RI.

Abstract
BACKGROUND Type 2 diabetes mellitus (T2DM) is a growing health problem worldwide. Whether sulphonylureas show better, equal or worse therapeutic effects in comparison with other antidiabetic interventions for patients with T2DM remains controversial. OBJECTIVES To assess the effects of sulphonylurea monotherapy versus placebo, no intervention or other antidiabetic interventions for patients with T2DM. SEARCH METHODS We searched publications in The Cochrane Library, MEDLINE, EMBASE, Science Citation Index Expanded, LILACS and CINAHL (all until August 2011) to obtain trials fulfilling the inclusion criteria for our review. SELECTION CRITERIA We included clinical trials that randomised patients 18 years old or more with T2DM to sulphonylurea monotherapy with a duration of 24 weeks or more. DATA COLLECTION AND ANALYSIS Two authors independently assessed the risk of bias. The primary outcomes were all-cause and cardiovascular mortality. Secondary outcomes were other patient-important outcomes and metabolic variables. Where possible, we used risk ratios (RR) with 95% confidence intervals (95% CI) to analyse the treatment effect of dichotomous outcomes. We used mean differences with 95% CI to analyse the treatment effect of continuous outcomes. We evaluated the risk of bias. We conducted trial sequential analyses to assess whether firm evidence could be established for a 10% relative risk reduction (RRR) between intervention groups. MAIN RESULTS We included 72 randomised controlled trials (RCTs) with 22,589 participants; 9707 participants randomised to sulphonylureas versus 12,805 participants randomised to control interventions. The duration of the interventions varied from 24 weeks to 10.7 years. We judged none of the included trials as low risk of bias for all bias domains. Patient-important outcomes were seldom reported.First-generation sulphonylureas (FGS) versus placebo or insulin did not show statistical significance for all-cause mortality (versus placebo: RR 1.46, 95% CI 0.87 to 2.45; P = 0.15; 2 trials; 553 participants; high risk of bias (HRB); versus insulin: RR 1.18, 95% CI 0.88 to 1.59; P = 0.26; 2 trials; 1944 participants; HRB). FGS versus placebo showed statistical significance for cardiovascular mortality in favour of placebo (RR 2.63, 95% CI 1.32 to 5.22; P = 0.006; 2 trials; 553 participants; HRB). FGS versus insulin did not show statistical significance for cardiovascular mortality (RR 1.36, 95% CI 0.68 to 2.71; P = 0.39; 2 trials; 1944 participants; HRB). FGS versus alpha-glucosidase inhibitors showed statistical significance in favour of FGS for adverse events (RR 0.63, 95% CI 0.52 to 0.76; P = 0.01; 2 trials; 246 participants; HRB) and for drop-outs due to adverse events (RR 0.28, 95% CI 0.12 to 0.67; P = 0.004; 2 trials; 246 participants; HRB).Second-generation sulphonylureas (SGS) versus metformin (RR 0.98, 95% CI 0.61 to 1.58; P = 0.68; 6 trials; 3528 participants; HRB), thiazolidinediones (RR 0.92, 95% CI 0.60 to 1.41; P = 0.70; 7 trials; 4955 participants; HRB), insulin (RR 0.96, 95% CI 0.79 to 1.18; P = 0.72; 4 trials; 1642 participants; HRB), meglitinides (RR 1.44, 95% CI 0.47 to 4.42; P = 0.52; 7 trials; 2038 participants; HRB), or incretin-based interventions (RR 1.39, 95% CI 0.52 to 3.68; P = 0.51; 2 trials; 1503 participants; HRB) showed no statistically significant effects regarding all-cause mortality in a random-effects model. SGS versus metformin (RR 1.47; 95% CI 0.54 to 4.01; P = 0.45; 6 trials; 3528 participants; HRB), thiazolidinediones (RR 1.30, 95% CI 0.55 to 3.07; P = 0.55; 7 trials; 4955 participants; HRB), insulin (RR 0.96, 95% CI 0.73 to 1.28; P = 0.80; 4 trials; 1642 participants; HRB) or meglitinide (RR 0.97, 95% CI 0.27 to 3.53; P = 0.97; 7 trials, 2038 participants, HRB) showed no statistically significant effects regarding cardiovascular mortality. Mortality data for the SGS versus placebo were sparse. SGS versus thiazolidinediones and meglitinides did not show statistically significant differences for a composite of non-fatal macrovascular outcomes. SGS versus metformin showed statistical significance in favour of SGS for a composite of non-fatal macrovascular outcomes (RR 0.67, 95% CI 0.48 to 0.93; P = 0.02; 3018 participants; 3 trials; HRB). The definition of non-fatal macrovascular outcomes varied among the trials. SGS versus metformin, thiazolidinediones and meglitinides showed no statistical significance for non-fatal myocardial infarction. No meta-analyses could be performed for microvascular outcomes. SGS versus placebo, metformin, thiazolidinediones, alpha-glucosidase inhibitors or meglitinides showed no statistical significance for adverse events. SGS versus alpha-glucosidase inhibitors showed statistical significance in favour of SGS for drop-outs due to adverse events (RR 0.48, 95% CI 0.24 to 0.96; P = 0.04; 9 trials; 870 participants; HRB). SGS versus meglitinides showed no statistical significance for the risk of severe hypoglycaemia. SGS versus metformin and thiazolidinediones showed statistical significance in favour of metformin (RR 5.64, 95% CI 1.22 to 26.00; P = 0.03; 4 trials; 3637 participants; HRB) and thiazolidinediones (RR 6.11, 95% CI 1.57 to 23.79; P = 0.009; 6 trials; 5660 participants; HRB) for severe hypoglycaemia.Third-generation sulphonylureas (TGS) could not be included in any meta-analysis of all-cause mortality, cardiovascular mortality or non-fatal macro- or microvascular outcomes. TGS versus thiazolidinediones showed statistical significance regarding adverse events in favour of TGS (RR 0.88, 95% CI 0.78 to 0.99; P = 0.03; 3 trials; 510 participants; HRB). TGS versus thiazolidinediones did not show any statistical significance for drop-outs due to adverse events. TGS versus other comparators could not be performed due to lack of data.For the comparison of SGS versus FGS no meta-analyses of all-cause mortality, cardiovascular mortality, non-fatal macro- or microvascular outcomes, or adverse events could be performed.Health-related quality of life and costs of intervention could not be meta-analysed due to lack of data.In trial sequential analysis, none of the analyses of mortality outcomes, vascular outcomes or severe hypoglycaemia met the criteria for firm evidence of a RRR of 10% between interventions. AUTHORS' CONCLUSIONS There is insufficient evidence from RCTs to support the decision as to whether to initiate sulphonylurea monotherapy. Data on patient-important outcomes are lacking. Therefore, large-scale and long-term randomised clinical trials with low risk of bias, focusing on patient-important outcomes are required.

Abstract
AIMS/HYPOTHESIS Recent studies suggest that proton pump inhibitor treatment may increase insulin secretion and improve glucose metabolism in type 2 diabetes. In a randomised double-blind prospective placebo-controlled 2 × 2 factorial study, we examined the effect of esomeprazole on insulin secretion, HbA(1c) and cardiovascular risk factors in type 2 diabetes. METHODS Forty-one patients with type 2 diabetes using dietary control or oral glucose-lowering treatment were randomised to receive add-on esomeprazole 40 mg (n = 20) or placebo (n = 21) for 12 weeks. Randomisation was carried out prior to inclusion on the basis of a computer-generated random-number list. The allocation sequence was concealed in sealed envelopes from the researcher enrolling and assessing participants. The study was undertaken at Steno Diabetes Center, Gentofte, Denmark. The primary outcome was change in AUC for insulin levels during a meal test. Secondary outcomes were the levels of HbA(1c) and biochemical markers of cardiovascular risk, including lipids, coagulation factors, inflammation markers, markers of endothelial function and 24 h ambulatory BP measurements. RESULTS Forty-one participants were analysed. In the esomeprazole-treated group the AUC for insulin did not change (before vs after treatment: 28,049 ± 17,659 vs 27,270 ± 32,004 pmol/l × min (p = 0.838). In the placebo group AUC for insulin decreased from 27,392 ± 14,348 pmol/l × min to 22,938 ± 11,936 pmol/l × min (p = 0.002). Esomeprazole treatment (n = 20) caused a ninefold increase in the AUC for gastrin. HbA(1c) increased from 7.0 ± 0.6% (53 ± 5 mmol/mol) to 7.3 ± 0.8% (56 ± 6 mmol/mol) in the esomeprazole-treated group and from 7.0 ± 0.6% (53 ± 5 mmol/mol) to 7.4 ± 0.8% (57 ± 6 mmol/mol) in the placebo group (n = 21) (p for difference in change >0.05). Except for BP, there were no differences between the groups in the markers of cardiovascular risk (p > 0.05). Monitoring of 24 h ambulatory BP showed a significant decrease in daytime systolic BP, daytime diastolic BP and 24 h diastolic BP in the placebo group (p < 0.05). No change in BP was seen in the patients treated with esomeprazole. CONCLUSIONS/INTERPRETATION Treatment with esomeprazole over 12 weeks did not improve insulin secretion, glycaemic control or cardiovascular disease biomarkers in patients with type 2 diabetes.

Abstract
OBJECTIVES To compare the benefits and harms of metformin and insulin versus insulin alone as reported in randomised clinical trials of patients with type 2 diabetes. DESIGN Systematic review of randomised clinical trials with meta-analyses and trial sequential analyses. DATA SOURCES The Cochrane Library, Medline, Embase, Science Citation Index Expanded, Latin American Caribbean Health Sciences Literature, and Cumulative Index to Nursing and Allied Health Literature until March 2011. We also searched abstracts presented at the American Diabetes Association and European Association for the Study of Diabetes Congresses, contacted relevant trial authors and pharmaceutical companies, hand searched reference lists of included trials, and searched the US Food and Drug Administration website. REVIEW METHODS Two authors independently screened titles and abstracts for randomised clinical trials comparing metformin and insulin versus insulin alone (with or without placebo) in patients with type 2 diabetes, older than 18 years, and with an intervention period of at least 12 weeks. We included trials irrespective of language, publication status, predefined outcomes, antidiabetic interventions used before randomisation, and reported outcomes. RESULTS We included 26 randomised trials with 2286 participants, of which 23 trials with 2117 participants could provide data. All trials had high risk of bias. Data were sparse for outcomes relevant to patients. Metformin and insulin versus insulin alone did not significantly affect all cause mortality (relative risk 1.30, 95% confidence interval 0.57 to 2.99) or cardiovascular mortality (1.70, 0.35 to 8.30). Trial sequential analyses showed that more trials were needed before reliable conclusions could be drawn regarding these outcomes. In a fixed effect model, but not in a random effects model, severe hypoglycaemia was significantly more frequent with metformin and insulin than with insulin alone (2.83, 1.17 to 6.86). In a random effects model, metformin and insulin resulted in reduced HbA(1c), weight gain, and insulin dose, compared with insulin alone; trial sequential analyses showed sufficient evidence for a HbA(1c) reduction of 0.5%, lower weight gain of 1 kg, and lower insulin dose of 5 U/day. CONCLUSIONS There was no evidence or even a trend towards improved all cause mortality or cardiovascular mortality with metformin and insulin, compared with insulin alone in type 2 diabetes. Data were limited by the severe lack of data reported by trials for patient relevant outcomes and by poor bias control.

Abstract
This review addresses the apparent disconnect between international guideline recommendations, real-life clinical practice and the results of clinical trials, with regard to the initiation of insulin using basal (long-acting) or premixed insulin analogues in patients with type 2 diabetes (T2D). English language guidelines vary considerably with respect to recommended glycaemic targets, the selection of human vs analogue insulin, and choice of insulin regimen. Randomised trials directly comparing insulin initiation between basal and premixed analogues are scarce, and hard endpoint outcome data are inadequate. The evidence presented suggests that a major component of the HbA1c not being attained in every day clinical practice may be a result of factors that are not adequately addressed in forced titration trials of highly motivated patients, including failure to comply with complex treatment and monitoring regimens. Enforced intensification of unrealistic complex treatment regimens and glycaemic targets may theoretically worsen the psychological well-being in some patients. More simple and sustainable treatment regimens and guidelines are urgently needed. As for the use of insulin in T2D, there is limited evidence to convincingly support that initiation of insulin using basal insulin analogues is superior to initiation using premixed insulin analogues. While awaiting improved clinical efficacy and cost-effectiveness data, practical guidance from national and international diabetes organisations should consider more carefully the importance of: i) being clear and consistent; and ii) the early implementation of sustainable and cost-effective insulin treatment regimens with an emphasis on optimising treatment ease of use and patient compliance.

Abstract
OBJECTIVE To assess the effect of targeting intensive glycaemic control versus conventional glycaemic control on all cause mortality and cardiovascular mortality, non-fatal myocardial infarction, microvascular complications, and severe hypoglycaemia in patients with type 2 diabetes. DESIGN Systematic review with meta-analyses and trial sequential analyses of randomised trials. DATA SOURCES Cochrane Library, Medline, Embase, Science Citation Index Expanded, LILACS, and CINAHL to December 2010; hand search of reference lists and conference proceedings; contacts with authors, relevant pharmaceutical companies, and the US Food and Drug Administration. STUDY SELECTION Randomised clinical trials comparing targeted intensive glycaemic control with conventional glycaemic control in patients with type 2 diabetes. Published and unpublished trials in all languages were included, irrespective of predefined outcomes. DATA EXTRACTION Two reviewers independently assessed studies for inclusion and extracted data related to study methods, interventions, outcomes, risk of bias, and adverse events. Risk ratios with 95% confidence intervals were estimated with fixed and random effects models. RESULTS Fourteen clinical trials that randomised 28,614 participants with type 2 diabetes (15,269 to intensive control and 13,345 to conventional control) were included. Intensive glycaemic control did not significantly affect the relative risks of all cause (1.02, 95% confidence interval 0.91 to 1.13; 28,359 participants, 12 trials) or cardiovascular mortality (1.11, 0.92 to 1.35; 28,359 participants, 12 trials). Trial sequential analyses rejected a relative risk reduction above 10% for all cause mortality and showed insufficient data on cardiovascular mortality. The risk of non-fatal myocardial infarction may be reduced (relative risk 0.85, 0.76 to 0.95; P=0.004; 28,111 participants, 8 trials), but this finding was not confirmed in trial sequential analysis. Intensive glycaemic control showed a reduction of the relative risks for the composite microvascular outcome (0.88, 0.79 to 0.97; P=0.01; 25,600 participants, 3 trials) and retinopathy (0.80, 0.67 to 0.94; P=0.009; 10,793 participants, 7 trials), but trial sequential analyses showed that sufficient evidence had not yet been reached. The estimate of an effect on the risk of nephropathy (relative risk 0.83, 0.64 to 1.06; 27,769 participants, 8 trials) was not statistically significant. The risk of severe hypoglycaemia was significantly increased when intensive glycaemic control was targeted (relative risk 2.39, 1.71 to 3.34; 27,844 participants, 9 trials); trial sequential analysis supported a 30% increased relative risk of severe hypoglycaemia. CONCLUSION Intensive glycaemic control does not seem to reduce all cause mortality in patients with type 2 diabetes. Data available from randomised clinical trials remain insufficient to prove or refute a relative risk reduction for cardiovascular mortality, non-fatal myocardial infarction, composite microvascular complications, or retinopathy at a magnitude of 10%. Intensive glycaemic control increases the relative risk of severe hypoglycaemia by 30%.

Abstract
BACKGROUND Patients with type 2 diabetes mellitus (T2D) exhibit an increased risk of cardiovascular disease and mortality compared to the background population. Observational studies report a relationship between reduced blood glucose and reduced risk of both micro- and macrovascular complications in patients with T2D. OBJECTIVES To assess the effects of targeting intensive versus conventional glycaemic control in T2D patients. SEARCH STRATEGY Trials were obtained from searches of CENTRAL (The Cochrane Library), MEDLINE, EMBASE, Science Citation Index Expanded, LILACS, and CINAHL (until December 2010). SELECTION CRITERIA We included randomised clinical trials that prespecified different targets of glycaemic control in adults with T2D. DATA COLLECTION AND ANALYSIS Two authors independently assessed the risk of bias and extracted data. Dichotomous outcomes were assessed by risk ratios (RR) and 95% confidence intervals (CI). MAIN RESULTS Twenty trials randomised 16,106 T2D participants to intensive control and 13,880 T2D participants to conventional glycaemic control. The mean age of the participants was 62.1 years. The duration of the intervention ranged from three days to 12.5 years. The number of participants in the included trials ranged from 20 to 11,140. There was no significant difference between targeting intensive and conventional glycaemic control for all-cause mortality (RR 1.01, 95% CI 0.90 to 1.13; 29,731 participants, 18 trials) or cardiovascular mortality (RR 1.06, 95% CI 0.90 to 1.26; 29,731 participants, 18 trials). Trial sequential analysis (TSA) showed that a 10% RR reduction could be refuted for all-cause mortality. Targeting intensive glycaemic control did not show a significant effect on the risk of non-fatal myocardial infarction in the random-effects model but decreased the risk in the fixed-effect model (RR 0.86, 95% CI 0.78 to 0.96; P = 0.006; 29,174 participants, 12 trials). Targeting intensive glycaemic control reduced the risk of amputation (RR 0.64, 95% CI 0.43 to 0.95; P = 0.03; 6960 participants, 8 trials), the composite risk of microvascular disease (RR 0.89, 95% CI 0.83 to 0.95; P = 0.0006; 25,760 participants, 4 trials), retinopathy (RR 0.79, 95% CI 0.68 to 0.92; P = 0.002; 10,986 participants, 8 trials), retinal photocoagulation (RR 0.77, 95% CI 0.61 to 0.97; P = 0.03; 11,142 participants, 7 trials), and nephropathy (RR 0.78, 95% CI 0.61 to 0.99; P = 0.04; 27,929 participants, 9 trials). The risks of both mild and severe hypoglycaemia were increased with targeting intensive glycaemic control but substantial heterogeneity was present. The definition of severe hypoglycaemia varied among the included trials; severe hypoglycaemia was reported in 12 trials that included 28,127 participants. TSA showed that firm evidence was reached for a 30% RR increase in severe hypoglycaemic when targeting intensive glycaemic control. Subgroup analysis of trials exclusively dealing with glycaemic control in usual care settings showed a significant effect in favour of targeting intensive glycaemic control for non-fatal myocardial infarction. However, TSA showed more trials are needed before firm evidence is established. AUTHORS' CONCLUSIONS The included trials did not show significant differences for all-cause mortality and cardiovascular mortality when targeting intensive glycaemic control compared with conventional glycaemic control. Targeting intensive glycaemic control reduced the risk of microvascular complications while increasing the risk of hypoglycaemia. Furthermore, intensive glycaemic control might reduce the risk of non-fatal myocardial infarction in trials exclusively dealing with glycaemic control in usual care settings.

Abstract
OBJECTIVE Metformin has been reported to reduce α-dicarbonyls, which are known to contribute to diabetic complications. It is unclear whether this is due to direct quenching of α-dicarbonyls or to an improvement in glycemic control. We therefore compared the effects of metformin versus repaglinide, an antihyperglycemic agent with an insulin-secreting mechanism, on the levels of the α-dicarbonyl 3-deoxyglucosone (3DG). METHODS We conducted a single-center, double-masked, double-dummy, crossover study involving 96 nonobese patients with type 2 diabetes. After a 1-month run-in on diet-only treatment, patients were randomized to either repaglinide (6 mg daily) followed by metformin (2 g daily) or vice versa each during 4 months with a 1-month washout between interventions. RESULTS 3DG levels decreased after both metformin (-19.3% (95% confidence interval (CI): -23.5, -14.8)) and repaglinide (-20.8% (95% CI: -24.9, -16.3)) treatments, but no difference was found between treatments (1.8% (95% CI: -3.8, 7.8)). Regardless of the treatment, changes in glycemic variables were associated with changes in 3DG. Specifically, 3DG decreased by 22.7% (95% CI: 19.0, 26.5) per s.d. decrease in fasting plasma glucose (PG), by 20.0% (95% CI: 16.2, 23.9) per s.d. decrease in seven-point mean plasma glucose, by 22.5% (95% CI: 18.6, 26.6) per s.d. decrease in area under the curve for PG, by 17.2% (95% CI: 13.8, 20.6) per s.d. decrease in HbAlc, and by 10.9% (95% CI: 6.4, 15.5) per s.d. decrease in Amadori albumin. In addition, decreases in 3DG were associated with decreases in advanced glycation endproducts and endothelial markers. CONCLUSION Improved glycemic control induced by both metformin and repaglinide is associated with a reduction in 3DG levels in nonobese individuals with type 2 diabetes. This may constitute a shared metabolic pathway through which both treatments have a beneficial impact on the cardiovascular risk.

Abstract
BACKGROUND
LDL cholesterol (LDL-C) is a modifiable cardiovascular disease risk factor. We used 3 LDL-C methods to study the agreement between fasting and postprandial LDL-C in type 2 diabetes (T2DM) patients.
METHODS
We served 74 T2DM patients a standardized meal and sampled blood at fasting and 1.5, 3.0, 4.5, and 6.0 h postprandially. We measured LDL-C by use of modified β quantification (MBQ), the Friedewald equation (FE), and a direct homogeneous assay (DA). We evaluated agreement using 95% limits of agreement (LOA) within ±0.20 mmol/L (±7.7 mg/dL).
RESULTS
LDL-C concentrations at all postprandial times disagreed with those at fasting for all methods. In 66 patients who had complete measurements with all LDL-C methods, maximum mean differences (95% LOA) in postprandial vs fasting LDL-C were −0.16 mmol/L (−0.51; 0.19) [−6.2 mg/dL (−19.7; 7.3)] with MBQ at 3 h; −0.36 mmol/L (−0.89; 0.17) [−13.9 mg/dL (−34; 6.6)] with FE at 4.5 h; and −0.24 mmol/L (−0.62; 0.05) [−9.3 mg/dL (−24; 1.9)] with DA at 6.0 h. In postprandial samples, FE misclassified 38% of patients (two-thirds of statin users) into lower Adult Treatment Panel III (ATP III) risk categories. Greater disagreement between fasting and postprandial LDL-C was observed in individuals with postprandial triglyceride concentrations >2.08 mmol/L (>184 mg/dL) and in women (interactions: P ≤ 0.038).
CONCLUSIONS
Differences up to 0.89 mmol/L (34 mg/dL) between fasting and postprandial LDL-C concentrations, with postprandial LDL-C concentrations usually being lower, were found in T2DM by 3 different LDL-C methods. Such differences are potentially relevant clinically and suggest that, irrespective of measurement method, postprandial LDL-C concentrations should not be used to assess cardiovascular disease risk.

Abstract
OBJECTIVES To study the effect of insulin treatment in combination with metformin or an insulin secretagogue, repaglinide, on glycaemic regulation in non-obese patients with type 2 diabetes. DESIGN Randomised, double blind, double dummy, parallel trial. SETTING Secondary care in Denmark between 2003 and 2006. PARTICIPANTS Non-obese patients (BMI </=27) with preserved beta cell function. INTERVENTIONS After a four month run-in period with repaglinide plus metformin combination therapy, patients with a glycated haemoglobin (HbA(1c)) concentration of 6.5% or more were randomised to repaglinide 6 mg or metformin 2000 mg. All patients also received biphasic insulin aspart 70/30 (30% soluble insulin aspart and 70% intermediate acting insulin aspart) 6 units once a day before dinner for 12 months. Insulin dose was adjusted aiming for a fasting plasma glucose concentration of 4.0-6.0 mmol/l. The target of HbA(1c) concentration was less than 6.5%. Treatment was intensified to two or three insulin injections a day if glycaemic targets were not reached. MAIN OUTCOME MEASURE HbA(1c) concentration. RESULTS Of the 459 patients who were eligible, 102 were randomised, and 97 completed the trial. Patients had had type 2 diabetes for approximately 10 years. At the end of treatment, HbA(1c) concentration was reduced by a similar amount in the two treatment groups (insulin plus metformin: mean (standard deviation) HbA(1c) 8.15% (1.32) v 6.72% (0.66); insulin plus repaglinide: 8.07% (1.49) v 6.90% (0.68); P=0.177). Total daily insulin dose and risk of hypoglycaemia were also similar in the two treatment groups. Weight gain was less with metformin plus biphasic insulin aspart 70/30 than with repaglinide plus biphasic insulin aspart 70/30 (difference in mean body weight between treatments -2.51 kg, 95% confidence interval -4.07 to -0.95). CONCLUSIONS In non-obese patients with type 2 diabetes and poor glycaemic regulation on oral hypoglycaemic agents, overall glycaemic regulation with insulin in combination with metformin was equivalent to that with insulin plus repaglinide. Weight gain seemed less with insulin plus metformin than with insulin plus repaglinide. TRIAL REGISTRATION NCT00118963.

Abstract
BACKGROUND In addition to its glucose-lowering effect, metformin treatment has been suggested to improve lipidaemia in patients with type 2 diabetes. In contrast, in patients with type 1 diabetes (T1DM), information about the effect of metformin treatment on lipidaemia is limited. In this study, we report the effect of a 1-year treatment with metformin vs. placebo on plasma lipids in T1DM patients and persistent poor glycaemic control. METHODS One hundred T1DM patients with haemoglobinA(1c) (HbA(1c)) > or =8.5% during the year before enrolment entered a 1-month run-in period on placebo treatment. Thereafter, patients were randomized (baseline) to treatment with either metformin (1000 mg twice daily) or placebo for 12 months (double masked). Patients continued ongoing insulin therapy and their usual outpatient clinical care. Outcomes were assessed at baseline and after 1 year. RESULTS After 1 year, in those patients who did not start or stop statin therapy during the trial, metformin treatment significantly reduced total and LDL cholesterol by approximately 0.3 mmol/l compared with placebo (p = 0.021 and p = 0.018 respectively). Adjustment for statin use or known cardiovascular disease did not change conclusions. In statin users (metformin: n = 22, placebo: n = 13), metformin significantly lowered levels of LDL and non-HDL cholesterol by approximately 0.5 mmol/l compared with placebo (adjusted for changes in statin dose or agent: p = 0.048 and p = 0.033 respectively). HbA(1c) (previously reported) was not significant different between treatments. CONCLUSION In patients with poorly controlled T1DM, at similar glycaemic levels, adjunct metformin therapy during 1 year significantly lowered levels of proatherogenic cholesterolaemia independent of statin therapy.
