Aims:To determine the effects of empagliflozin on blood pressure (BP) and markers of arterial stiffness and vascular resistance in patients with type 2 diabetes mellitus (T2DM). Methods:We conducted a post hoc analysis of data from a phase III trial in patients with T2DM and hypertension receiving 12 weeks' empagliflozin and four phase III trials in patients with T2DM receiving 24 weeks' empagliflozin (cohort 1, n = 823; cohort 2, n = 2477). BP was measured using 24-h BP monitoring (cohort 1) or seated office measurements (cohort 2).Results: Empagliflozin reduced systolic BP (SBP) and diastolic BP in both cohorts (p < 0.001 vs placebo), without increasing heart rate. Empagliflozin reduced pulse pressure (PP; adjusted mean difference vs placebo cohort 1: −2.3 mmHg; cohort 2: −2.3 mmHg), mean arterial pressure (MAP; cohort 1, −2.3 mmHg; cohort 2, −2.1 mmHg) and double product (cohort 1, −385 mmHg × bpm; cohort 2, −369 mmHg × bpm) all p < 0.001 vs placebo. There was a trend towards a reduction in the ambulatory arterial stiffness index (AASI) with empagliflozin in cohort 1 (p = 0.059 vs placebo). AASI was not measured in cohort 2. Subgroup analyses showed that there were greater reductions in PP with increasing baseline SBP in cohort 1 (p = 0.092). In cohort 2, greater reductions in MAP were achieved in patients with higher baseline SBP (p = 0.027) and greater reductions in PP were observed in older patients (p = 0.011). Conclusions IntroductionCardiovascular (CV) disease is the major cause of morbidity and mortality in patients with type 2 diabetes (T2DM) [1]. The risk of CV disease in adults with diabetes is double that in adults without diabetes, and diabetes is estimated to account for 10-12% of all vascular deaths [2]. Patients with T2DM often have numerous CV risk factors and a multifactorial approach to addressing CV risk, including controlling glycaemia, blood pressure (BP) and body weight, is recommended in these patients [1,3].The metabolic abnormalities that are characteristic of diabetes, such as hyperglycaemia, excess free fatty acids and insulin resistance, can lead to suppression of nitric oxide production and activation of the renin-angiotensin system, leading to oxidative stress, endothelial dysfunction and activation of the receptor for advanced glycation end products (RAGE) [4][5][6]. These may contribute to hypertension [7] or to increased arterial stiffness related to vascular calcification or accumulation ofCorrespondence to: Odd Erik Johansen, Boehringer Ingelheim Norway KS, Asker, Norway.

OBJECTIVESodium–glucose cotransporter 2 (SGLT2) inhibitors cause substantially less weight loss than expected from the energy excreted via glycosuria. Our aim was to analyze this phenomenon quantitatively.RESEARCH DESIGN AND METHODSEighty-six patients with type 2 diabetes (HbA1c 7.8 ± 0.8% [62 ± 9 mmol/mol], estimated glomerular filtration rate [eGFR] 89 ± 19 mL ⋅ min−1 ⋅ 1.73 m−2) received empagliflozin (25 mg/day) for 90 weeks with frequent (n = 11) assessments of body weight, eGFR, and fasting plasma glucose (FPG). Time-dependent glucose filtration was calculated as the product of eGFR and FPG; time-dependent glycosuria was estimated from previous direct measurements. The relation of calorie-to-weight changes was estimated using a mathematical model of human energy metabolism that simulates the time course of weight change for a given change in calorie balance and calculates the corresponding energy intake changes.RESULTSAt week 90, weight loss averaged −3.2 ± 4.2 kg (corresponding to a median calorie deficit of 51 kcal/day [interquartile range (IQR) 112]). However, the observed calorie loss through glycosuria (206 kcal/day [IQR 90]) was predicted to result in a weight loss of –11.3 ± 3.1 kg, assuming no compensatory changes in energy intake. Thus, patients lost only 29 ± 41% of the weight loss predicted by their glycosuria; the model indicated that this difference was accounted for by a 13% (IQR 12) increase in calorie intake (269 kcal/day [IQR 258]) coupled with a 2% (IQR 5) increase in daily energy expenditure (due to diet-induced thermogenesis). This increased calorie intake was inversely related to baseline BMI (partial r = −0.34, P < 0.01) and positively to baseline eGFR (partial r = 0.29, P < 0.01).CONCLUSIONSChronic glycosuria elicits an adaptive increase in energy intake. Combining SGLT2 inhibition with caloric restriction is expected to be associated with major weight loss.

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.

This updated and expanded pooled, post hoc analysis of 22 placebo-controlled trials of linagliptin 5 mg daily supports previous findings of the acceptable overall safety/tolerability profile of linagliptin when administered to a broad range of patients with T2DM. Linagliptin-treated patients demonstrated a low overall risk of hypoglycemia (risk increased by concomitant sulfonylurea therapy). As with all pooled analyses, this study is limited by the use of data from different studies, and the relatively short duration of some included studies, although use of individual patient data from consistently designed trials should minimize methodological differences between trials. Results from ongoing clinical trials will provide additional insight into the long-term safety/tolerability of linagliptin.

BackgroundThis study was performed to evaluate the outcome after hemostatic radiotherapy (RT) of significant bleeding in incurable cancer patients.MethodsPatients treated by hemostatic RT between November 2006 and February 2010 were retrospectively analyzed. Bleeding was assessed according to the World Health Organization (WHO) scale (grade 0 = no bleeding, 1 = petechial bleeding, 2 = clinically significant bleeding, 3 = bleeding requiring transfusion, 4 = bleeding associated with fatality). The primary endpoint was bleeding at the end of RT. Key secondary endpoints included overall survival (OS) and acute toxicity. The bleeding score before and after RT were compared using the Wilcoxon signed rank test. Time to event endpoints were estimated using the Kaplan Meier method.ResultsOverall 62 patients were analyzed including 1 patient whose benign cause of bleeding was pseudomyxoma peritonei. Median age was 66 (range, 37–93) years. Before RT, bleeding was graded as 2 and 3 in 24 (39%) and 38 (61%) patients, respectively. A median dose of 20 (range, 5–45) Gy of hemostatic RT was applied to the bleeding site. At the end of RT, there was a statistically significant difference in bleeding (p < 0.001); it was graded as 0 ( n = 39), 1 ( n = 12), 2 ( n = 6), 3 ( n = 4) and 4 (n = 1). With a median follow-up of 19.3 (range, 0.3-19.3) months, the 6-month OS rate was 43%. Forty patients died (65%); 5 due to bleeding. No grade 3 or above acute toxicity was observed.ConclusionsHemostatic RT seems to be a safe and effective treatment for clinically and statistically significantly reducing bleeding in incurable cancer patients.
