    ABSTRACT: AimsExamine the association between weight loss and adherence with glycaemic goal attainment in patients with inadequately controlled T2DM.Materials and methodsPatients ≥ 18 years with T2DM from a US integrated health system starting a new class of diabetes medication between 11/1/10 and 4/30/11 (index date) with baseline HbA1c ≥ 7.0% were included in this cohort study. Target HbA1c and weight change were defined at 6-months as HbA1c < 7.0% and ≥ 3% loss in body weight. Patient-reported medication adherence was assessed per the Medication Adherence Reporting Scale. Structural equation modelling was used to describe simultaneous associations between adherence, weight loss and HbA1c goal attainment.ResultsInclusion criteria were met by 477 patients; mean (SD) age 59.1 (11.6) years; 50.9% were female; 30.4% were treatment naïve; baseline HbA1c 8.6% (1.6); weight 102.0 kg (23.0). Most patients (67.9%) reported being adherent to the index diabetes medication. At 6 months mean weight change was −1.3 (5.1) kg (p = 0.39); 28.1% had weight loss of ≥ 3%. Mean HbA1c change was −1.2% (1.8) (p< 0.001); 42.8% attained HbA1c goal. Adherent patients (OR 1.70; p = 0.02) and diabetes therapies that lead to weight loss (metformin, GLP-1) were associated with weight loss ≥ 3% (OR 2.96; p< 0.001). Weight loss (OR 3.60; p < 0.001) and adherence (OR 1.59; p < 0.001) were associated with HbA1c goal attainment.Conclusions Weight loss ≥ 3% and medication adherence were associated with HbA1c goal attainment in T2DM; weight loss was a stronger predictor of goal attainment than medication adherence in this study population. It is important to consider weight-effect properties, in addition to patient-centric adherence counselling, when prescribing diabetes therapy.

    ABSTRACT: Type 2 diabetes mellitus (T2DM) carries significant risks for coronary heart disease (CHD). We examined the potential US population impact of single and composite risk factor control. Among US adults with diagnosed T2DM aged ≥30 years in the National Health and Nutrition Examination Survey 2007 to 2012, we assessed CHD events preventable using the United Kingdom Prospective Diabetes Study CHD risk engine. We examined in all those not at goal the impact of statistical control of smoking, glycated hemoglobin, systolic blood pressure, and total and high-density lipoprotein cholesterol, according to the predefined criteria setting risk factors at different levels of control representing (1) "All to Goal," (2) at "Nominal Control," or (3) at "Aggressive Control." Preventable CHD events represented the difference between the number of events estimated from the control of these risk factors versus current levels of the risk factors. Of 606 men (representing 6.2 million) and 603 women (6.3 million) with DM and no previous CHD, 1.3 million men and 0.7 million women would develop a CHD event within 10 years if left uncontrolled. Controlling all risk factors to goal was projected to prevent 35% and 45% of CHD events in men and women, respectively. Nominal risk factor control was projected to prevent 36% and 38% and aggressive control 51% and 61% of CHD events, respectively. In conclusion, a significant proportion of CHD events in adults with T2DM could be prevented from composite control of risk factors often not at goal.

    ABSTRACT: Dapagliflozin, a sodium-glucose cotransporter 2 (SGLT-2) inhibitor, has been shown to lower HbA1c, weight, blood pressure, and serum uric acid in clinical trials. Plasma lipids were also evaluated as exploratory variables. The goal of this study was to estimate the long-term cardiovascular (CV) and microvascular outcomes of dapagliflozin added to the standard of care (SOC) vs SOC using simulation methodology. The Archimedes Model, a validated model of human physiology, diseases, and healthcare systems, was used to model a T2DM population derived from NHANES with HbA1c 7%-10%, taking a single oral antidiabetic agent (metformin, SU, or TZD) at the beginning of the trial. A 20-year trial was simulated comparing dapagliflozin 10 mg, given in addition to SOC, with SOC alone. SOC was based on ADA/EASD 2012 guidelines and included diet, metformin, SU, TZD, DPP-4, GLP-1, and insulin therapies, with usage levels reflective of those in NHANES. Dapagliflozin effects were derived from phase 3 clinical trial results. End points included CV and microvascular outcomes. Over a 20-year period, patients on dapagliflozin were projected to experience relative reductions in the incidence of MI, stroke, CV death, and all-cause death of 13.8%, 9.1%, 9.6%, and 5.0%, respectively, and relative reductions in the incidence of ESRD, foot amputation, and diabetic retinopathy of 18.7%, 13.0%, and 9.8%, respectively, when compared with SOC. Based on these simulation results, adding dapagliflozin to currently available treatment options is projected to further decrease the CV and microvascular complications associated with T2DM.

    ABSTRACT: Background:Most patients with type 2 diabetes mellitus (T2DM) suffer from cardiovascular disease (CVD). Whether CVD risk factors have improved in those with DM with and without CVD is not established. We compared risk factor levels and goal attainment in US adults with diabetes with and without CVD.Methods:We examined 2403 adults (aged ≥ 18 years) in the United States with T2DM (n = 654, 27% with CVD) across 1999-2010 using the US National Health and Nutrition Examination Survey (NHANES) and evaluated control of hemoglobin A1c (HbA1c), blood pressure (BP), low-density lipoprotein cholesterol (LDL-C) and body mass index (BMI) in those with DM with versus without CVD.Results:The proportions controlled for HbA1c, BP and LDL-C have improved (p < 0.001) overall between 1999 and 2010, but only 24% were at goal for all three factors in 2009-2010. There were improvements in BP, triglycerides and LDL-C in those with CVD, and in those without CVD, there were also improvements in control of all parameters, although changes in mean levels of risk factors were less impressive.Conclusion:Despite modest improvement over time, in most CVD risk factors, only one-fourth of those with T2DM are at goal for HbA1c, BP and LDL-C, with improvements seen in those without CVD more often than those with CVD.

    ABSTRACT: Obesity and alcohol interact to increase the risk of death from liver failure in men. In the present study, we aimed to examine whether obesity and alcohol were multiplicative or additive in increasing the risk of hepatocellular carcinoma (HCC) in both men and women. We conducted a prospective, population-based study of 23,712 Taiwanese residents (50.3% men) from 7 townships who underwent an evaluation for liver disease and were followed for 11.6 years for incident HCC. The mean age was 47 (standard deviation, 10) years and the mean body mass index (weight (kg)/height (m)(2)) was 24 (standard deviation, 3). Overall, 305 cases of HCC were identified over 275,126 person-years of follow-up. Age, male sex, alcohol drinking, cigarette smoking, elevated alanine aminotransferase, serum hepatitis B surface antigen, anti-hepatitis C virus positivity, and diabetes mellitus were each statistically significant predictors of incident HCC in univariate analyses (P < 0.05). Alcohol use and obesity (body mass index ≥30) showed a synergistic association with the risk of incident HCC in both unadjusted analyses (hazard ratio = 7.19, 95% confidence interval: 3.69, 14.00; P < 0.01) and multivariable-adjusted analyses (age, sex, smoking, serum alanine aminotransferase, serum hepatitis B surface antigen, anti-hepatitis C virus antibody, and diabetes mellitus) (hazard ratio = 3.82, 95% confidence interval: 1.94, 7.52; P < 0.01). Relative excess risks due to interaction, attributable proportion, and synergy index were 4.83, 0.67, and 4.53, respectively, suggesting a multiplicative interaction between alcohol use and obesity. Obesity and alcohol synergistically increase the risk of incident HCC.

    ABSTRACT: Data on glucose and cardiovascular disease (CVD) risk factor control among persons with type 2 diabetes mellitus (DM) according to insulin treatment status are lacking. We examined DM control, risk factors, and comorbidities among U.S. persons according to insulin treatment status. In the U.S. National Health and Nutrition Examination Surveys 2003-2006, we examined in 10,637 adults aged ≥30 with type 2 DM the extent of control of A1c, LDL-C, HDL-C, triglycerides, and blood pressure (BP) and composite goal attainment by insulin use status. 6.6% (n=889, projected to 14.3 million) had type 2 DM; of these, 22.9% were insulin users and 57.2% were treated only by other diabetes medications. Overall, 58.2% had an A1c<7% (53 mmol/mol) (insulin users 33.1%, non-insulin treated 66.1%, and 77.9% of those not on medication, p<0.0001). Overall, 44.2% were at a BP goal of <130/80 mmHg, 43.8% had an LDL-C<100 mg/dl (2.6 mmol/L), and 13.9% a BMI<25 kg/m(2). Only 10.2% were simultaneously at A1c, LDL, and BP goals (5.4% of those on insulin). U.S. adults with type 2 DM, especially those treated with insulin remain inadequately controlled for A1c and CVD risk factors and have a high prevalence of comorbidities.

    ABSTRACT: Diabetes mellitus (DM) is often considered a risk equivalent for cardiovascular disease (CVD); however, the variation in CVD risk in adults with DM has not been described. We studied 1114 US adults aged ≥18 years with DM from national survey data and the proportion at low (<10%), intermediate (10-20%) and high (>20%) risk, or with CVD, by age, gender, ethnicity and diabetes type and treatment, and glycaemic and risk factor control by risk group. Overall, 22.9% were low, 17.5% intermediate, 31.4% high risk and 28.2% had pre-existing CVD (total 59.6% high risk/CVD). More Hispanics (32.4%) and Blacks (30.6%) versus Whites (18.8%) were at lower risk (p<0.0001). Among type 1 versus 2 DM, 35% vs. 65% (p<0.0001) and among insulin users 68.1% were high risk or with CVD. However, among low-intermediate risk, >50% have metabolic syndrome and 7% chronic kidney disease, increasing the high risk/CVD group to 86.8%. Simultaneous achievement of HbA1c, blood pressure and low density lipoprotein-cholesterol goals was low (<15%) regardless of risk group. Many DM patients are not at high 10-year CVD risk, but metabolic factors may place them at greater long-term risk. Risk assessment could help target the intensity of treatment.

    ABSTRACT: Long-term treatment with entecavir resulted in durable virologic suppression and continued histologic improvement in nucleoside-naive chronic hepatitis B patients. Patients with advanced fibrosis or cirrhosis, who received long-term entecavir treatment, were evaluated for improvement in liver histology. The study included a subset of patients from phase III and long-term rollover studies, who received entecavir for at least 3 years, had advanced fibrosis or cirrhosis, and evaluable biopsies at baseline and after long-term treatment. Ten patients had advanced fibrosis or cirrhosis at baseline (Ishak fibrosis score, ≥ 4). After approximately 6 years of cumulative entecavir therapy (range, 267-297 wk), all 10 patients showed improvement in liver histology and Ishak fibrosis score. The mean change from baseline in Ishak fibrosis and Knodell necroinflammatory scores were -2.2 and -7.6, respectively. A reduction in Ishak fibrosis score to 4 or less was observed for all 4 patients who had cirrhosis at baseline. Chronic hepatitis B patients with advanced fibrosis or cirrhosis demonstrated histologic improvement and reversal of fibrosis and cirrhosis after long-term treatment with entecavir.

    ABSTRACT: Body mass index (BMI) and alcohol use are risk factors for hepatocellular carcinoma (HCC). We performed a prospective study to determine if these factors have synergistic effects on HCC risk. Over 14 years, we followed up 2260 Taiwanese men from the Risk Evaluation of Viral Load Elevation and Associated Liver Disease/Cancer-Hepatitis B Virus (REVEAL-HBV) Study Cohort who tested positive for the hepatitis B surface antigen (mean age, 46 ± 10 y; mean BMI, 24 ± 3 kg/m(2)); 20% reported alcohol use. Incident HCC cases were identified via linkage to the national cancer registry. Multivariate-adjusted hazard ratio (HR) and 95% confidence interval (CI) were estimated using Cox-proportional hazards models. In univariate analysis, the interaction between BMI and alcohol predicted incident HCC (P = .029). Alcohol use and extreme obesity (BMI ≥30 kg/m(2)) had synergistic effects on the risk of incident HCC in analyses adjusted for age (HR, 3.41; 95% CI, 1.25-9.27; P < .025) and multivariables (HR, 3.40; 95% CI, 1.24-9.34; P < .025). The relative risk estimate for the interaction and the attributable proportion from the interaction and synergy index were 1.59, 0.52, and 4.40, respectively; these indicate a multiplicative interaction between alcohol use and extreme obesity. In an analysis stratified into 4 World Health Organization categories of BMI and alcohol use, the risk of incident HCC increased in overweight (HR, 2.4; 95% CI, 1.3-4.4), obese (HR, 2.0; 95% CI, 1.1-3.7), and extremely obese (HR, 2.9; 95% CI, 1.0-8.0) users of alcohol (P for trend = .046). Obesity and alcohol have synergistic effects to increase the risk of incident HCC in hepatitis B surface antigen-positive men. Lifestyle interventions might reduce the incidence of HCC.

    ABSTRACT: One year of treatment with entecavir (0.5 mg daily) in nucleoside-naive patients with hepatitis B e antigen (HBeAg)-positive or HBeAg-negative chronic hepatitis B (CHB) resulted in significantly improved liver histology and virological and biochemical endpoints in comparison with lamivudine. Patients who received at least 3 years of cumulative entecavir therapy in phase 3 studies and a long-term rollover study and underwent long-term liver biopsy were evaluated for improvements in histological appearance. Sixty-nine patients [50 HBeAg-positive and 19 HBeAg-negative] receiving entecavir therapy underwent long-term liver biopsy (median time of biopsy = 6 years, range = 3-7 years). Histological improvement was analyzed for 57 patients who had adequate baseline biopsy samples, baseline Knodell necroinflammatory scores > or =2, and adequate long-term biopsy samples. At the time of long-term biopsy, all patients in the cohort had a hepatitis B virus DNA level <300 copies/mL, and 86% had a normalized alanine aminotransferase level. Histological improvement (> or =2-point decrease in the Knodell necroinflammatory score and no worsening of the Knodell fibrosis score) was observed in 96% of patients, and a > or =1-point improvement in the Ishak fibrosis score was found in 88% of patients, including all 10 patients with advanced fibrosis or cirrhosis at the phase 3 baseline. CONCLUSION: The majority of nucleoside-naive patients with CHB who were treated with entecavir in this long-term cohort achieved substantial histological improvement and regression of fibrosis or cirrhosis.

    ABSTRACT: Sustained virologic suppression is a primary goal of therapy for chronic hepatitis B (CHB). In study entecavir (ETV)-022, 48 weeks of entecavir 0.5 mg was superior to lamivudine for virologic suppression for hepatitis B e antigen (HBeAg)-positive CHB. A total of 183 entecavir-treated patients from ETV-022 subsequently enrolled in study ETV-901. We present the results after up to 5 years (240 weeks) of continuous entecavir therapy. The entecavir long-term cohort consists of patients who received >or=1 year of entecavir 0.5 mg in ETV-022 and then entered ETV-901 with a treatment gap <or=35 days. In ETV-901 the entecavir dose was 1.0 mg daily. For patients with samples available at Year 5, proportions with hepatitis B virus (HBV) DNA <300 copies/mL, normal alanine aminotransferase (ALT) levels, HBeAg loss, and HBeAg seroconversion were determined. In all, 146 patients met criteria for inclusion in the entecavir long-term cohort. At Year 5, 94% (88/94) had HBV DNA <300 copies/mL and 80% (78/98) had normal ALT levels. In addition to patients who achieved serologic responses during study ETV-022, 23% (33/141) achieved HBeAg seroconversion and 1.4% (2/145) lost hepatitis B surface antigen (HBsAg) during study ETV-901. Through 5 years, entecavir resistance emerged in one patient. The safety profile of entecavir was consistent with previous reports. CONCLUSION: Extended therapy with entecavir through 5 years maintained or increased rates of HBV DNA suppression and ALT normalization. Additional patients also achieved HBeAg loss and seroconversion. Entecavir provides sustained viral suppression with minimal resistance during long-term treatment of HBeAg-positive CHB.

    ABSTRACT: Of estimated 112 million persons infected with chronic hepatitis B (CHB) in China, 15% to 40% will eventually develop liver complications. Most patients do not actively seek antiviral agents for treatment due in part to lack of good understanding of the disease. Entecavir is a new therapeutic option for CHB patients and the purpose of this study was to evaluate the cost-effectiveness of entecavir treatment in China, based on projected clinical benefits from its superior viral suppression efficacy.

    ABSTRACT: Chronic hepatitis B (CHB) virus infection is a major global healthcare problem. The recent introduction of entecavir in Australia for the treatment of CHB patients in the naive treatment setting has triggered significant optimism with regards to improved clinical outcomes for CHB patients. To estimate, from an Australian healthcare perspective, the cost effectiveness of entecavir 0.5 mg/day versus lamivudine 100 mg/day in the treatment of CHB patients naive to nucleos(t)ide therapy. A cost-utility analysis to project the clinical and economic outcomes associated with CHB disease and treatment was conducted by developing two decision-tree models specific to hepatitis B e antigen-positive (HBeAg+ve) and HBeAg-ve CHB patient subsets. This analysis was constructed using the Australian payer perspective of direct costs and outcomes, with indirect medical costs and lost productivity not being included. The study population comprised a hypothetical cohort of 1000 antiviral treatment-naive CHB patients who received either entecavir 0.5 mg/day or lamivudine 100 mg/day at model entry. The population of patients used in this analysis was representative of those patients likely to receive initial antiviral therapy in clinical practice in Australia. The long-term cost effectiveness of entecavir compared with lamivudine in the first-line treatment of CHB patients was expressed as an incremental cost per life-year gained (LYG) or QALY gained. Results revealed that the availability of entecavir 0.5 mg/day as part of the Australian hepatologist's treatment armamentarium should result in significantly lower future rates of compensated cirrhosis (CC), decompensated cirrhosis (DC), and hepatocellular carcinoma (HCC) events (i.e. 54 fewer cases of CC, seven fewer cases of DC, and 20 fewer cases of HCC over the model's timeframe for HBeAg+ve CHB patients, and 69 fewer cases of CC, eight fewer cases of DC and 25 fewer cases of HCC over the model's timeframe for HBeAg-ve CHB patients). Compared with lamivudine 100 mg/day, entecavir 0.5 mg/day generated an estimated incremental cost per LYG of Australian dollars ($A, year 2006 values) 5046 and an estimated incremental cost per QALY of $A5952 in the HBeAg+ve CHB patient population, an estimated incremental cost per LYG of $A7063 and an estimated incremental cost per QALY of $A8003 in the HBeAg-ve CHB patient population, and an overall estimated incremental cost per LYG of $A5853 and an estimated incremental cost per QALY of $A6772 in the general CHB population. The availability of entecavir in Australian clinical practice should make long-term suppression of hepatitis B virus replication increasingly attainable, resulting in fewer CHB sequelae, at an acceptable financial cost.
