Faster Aspart Versus Insulin Aspart as Part of a Basal-Bolus Regimen in Inadequately Controlled Type 2 Diabetes: The onset 2 Trial.

OBJECTIVE: This multicenter, double-blind, treat-to-target, phase 3 trial evaluated the efficacy and safety of fast-acting insulin aspart (faster aspart) versus insulin aspart (IAsp) in adults with type 2 diabetes receiving basal insulin and oral antidiabetic agents. RESEARCH DESIGN AND METHODS: The primary end point was HbA1c change from baseline after 26 weeks' treatment. After an 8-week run-in to optimize basal insulin, subjects were randomized (1:1) to mealtime faster aspart (n = 345) or IAsp (n = 344), titrated using a simple daily patient-driven algorithm, plus insulin glargine U100 and metformin. RESULTS: HbA1c change was -1.38% (faster aspart) and -1.36% (IAsp); mean HbA1c was 6.6% for both groups. Faster aspart demonstrated noninferiority versus IAsp in reducing HbA1c (estimated treatment difference [ETD] [95% CI] -0.02% [-0.15; 0.10]). Both treatments improved postprandial plasma glucose (PPG) control; the PPG increment (liquid meal test) was statistically significant in favor of faster aspart after 1 h (ETD [95% CI] -0.59 mmol/L [-1.09; -0.09]; -10.63 mg/dL [-19.56; -1.69]; P = 0.0198), but not after 2-4 h. Change from baseline in fasting plasma glucose, body weight, and overall severe/blood glucose-confirmed hypoglycemia rates (rate ratio [RR] [95% CI] 1.09 [0.88; 1.36]) were similar between treatments. Postmeal hypoglycemia (0-2 h) rates were 2.27 (faster aspart) and 1.49 (IAsp) per patient-year of exposure (RR [95% CI] 1.60 [1.13; 2.27]). CONCLUSIONS: Faster aspart and IAsp were confirmed noninferior in a basal-bolus regimen regarding change from baseline in HbA1c. Faster aspart improved 1-h PPG with no differences in 2-4-h PPG versus IAsp. Overall hypoglycemia rates were similar except for an increase in 0-2-h postmeal hypoglycemia with faster aspart.

Reduced risk of hypoglycemia with insulin degludec versus insulin glargine in patients with type 2 diabetes requiring high doses of basal insulin: a meta-analysis of 5 randomized begin trials.

OBJECTIVE: This meta-analysis of 5 trials from the Phase 3a insulin degludec (IDeg) clinical trial program evaluated the risk of hypoglycemia in a subset of subjects with type 2 diabetes (T2D) who required high basal insulin doses at the end of the trials. METHODS: This meta-analysis compared glycated hemoglobin (HbA1c), fasting plasma glucose (FPG), basal insulin dose, body weight, and rates of overall and nocturnal confirmed hypoglycemia in a pooled population of T2D subjects using >60 U basal insulin at trial completion. Five Phase 3a, open-label, randomized, treat-to-target, confirmatory 26- or 52-week trials with IDeg (n = 2,262) versus insulin glargine (IGlar) (n = 1,110) administered once daily were included. Overall confirmed hypoglycemia was defined as self-measured blood glucose >56 mg/dL or any episode requiring assistance; nocturnal confirmed hypoglycemia had an onset between 00:01 and 05:59 AM. RESULTS: More than one-third of IDeg- (35%) and IGlar- (34%) treated T2D subjects required >60 U of basal insulin daily at the ends of the trial. Patients achieved similar mean HbA1c values (estimated treatment difference [ETD] IDeg - IGlar: 0.05%, P = .44) while mean FPG values were lower with IDeg than IGlar (ETD: -5.9 mg/dL, P = .04) at end-of-trial. There was a 21% lower rate of overall confirmed hypoglycemic episodes for IDeg (estimated rate ratio [RR] IDeg/IGlar: 0.79, P = .02) and a 52% lower rate of nocturnal confirmed hypoglycemic episodes for IDeg (RR: 0.48, P<.01). CONCLUSION: In this post hoc meta-analysis, more than 30% of subjects with T2D required >60 U/day of basal insulin at the end of the trials. In these individuals, IDeg achieves similar HbA1c reduction with significantly less overall and nocturnal confirmed hypoglycemia compared with IGlar.

Risk factors for venous thromboembolism during pregnancy.

BACKGROUND: Pregnant women are at an increased risk of venous thromboembolism (VTE). Risk factors for VTE among pregnant women are not sufficiently investigated. PURPOSE: To examine pharmacological and non-pharmacological VTE risk factors during pregnancy (antepartum). METHODS: The population comprised all pregnant women in Denmark aged 15-50 giving birth 2003-2010. Pregnancies were linked on an individual level with national registers for hospital admissions and drug dispenses from pharmacies. Risk of first occurring VTE antepartum was examined with Cox regression models. RESULTS: Out of 299 810 pregnancies, 337 experienced a VTE, incidence rate 1.1 (95% confidence interval [CI] 1.0-1.3) per 1000 pregnancies. Being underweight (body mass index [BMI] < 18.5 kg/m(2) ) was associated with a decreased risk of VTE (hazard ratio [HR] 0.53 [CI 0.29-0.98]) compared to normal weight (18.5 ≤ BMI < 25 kg/m(2) ). Overweight (25 ≤ BMI < 30 kg/m(2) ) increased VTE risk (HR 1.30 [CI 1.01-1.67]) but obesity (BMI ≥ 30 kg/m(2) ) was insignificant (HR 1.14 [CI 0.82-1.58]). A history of VTE was highly significant (HR 72.65 [CI 51.17-103.15]). The youngest (<20 years) and oldest (≥35 years) had insignificantly increased risks (HR 1.45 [CI 0.80-2.62] and HR 1.31 [CI 0.98-1.75], respectively) compared to those aged 20-30 years. Sixteen groups of medications, including anti-infectious medications, hormones, aminosalicylic acid, insulin, and benzodiazepine derivatives, were associated with VTE. CONCLUSION: The risk of antepartum VTE was increased in women with prior VTE. Compared to normal weight women, being underweight decreased the risk of VTE whereas being overweight increased the risk. Also, the use of several medications was associated with increased risk of VTE.

Discontinuation of hormone replacement therapy after myocardial infarction and short term risk of adverse cardiovascular events: nationwide cohort study.

OBJECTIVE: To assess the risk of adverse cardiovascular events in women who discontinue hormone replacement therapy after myocardial infarction compared with those who continue. DESIGN: Nationwide register based cohort study. SETTING: All hospitals in Denmark. POPULATION: All 3322 women aged 40 years or over who survived 30 days after a myocardial infarction and were prescribed hormone replacement therapy at the time of myocardial infarction in the period 1997 to 2008. MAIN OUTCOME MEASURES: Reinfarction, cardiovascular mortality, and all cause mortality 30 to 360 days after discharge.: RESULTS: A total of 282 (8.5%) women had a reinfarction, 218 (6.6%) died of cardiovascular causes, and 357 (10.7%) died of any cause during follow-up. Women who discontinued overall hormone replacement therapy in the first year after myocardial infarction did not have a significantly different risk of reinfarction (hazard ratio 0.90, 95% confidence interval 0.68 to 1.19), cardiovascular mortality (1.21, 0.90 to 1.62), or all cause mortality (1.22, 0.97 to 1.53) than women who continued use. However, discontinuation of vaginal oestrogen was associated with a lower risk of reinfarction (hazard ratio 0.54, 0.34 to 0.86). CONCLUSION: No certain conclusions can be drawn regarding increased or decreased risk of adverse cardiovascular events with continuing hormone replacement therapy after myocardial infarction. The results rule out neither a modest benefit nor a worrisome increase in risk. These figures may be valuable when a possible cardiovascular risk of hormone replacement therapy needs to be balanced with menopausal symptoms for the individual patient.

Hormone replacement therapy and risk of new-onset atrial fibrillation after myocardial infarction--a nationwide cohort study.

OBJECTIVES: Our aim was to assess the association between use of hormone replacement therapy (HRT) and risk of new-onset atrial fibrillation (AF) after myocardial infarction. DESIGN, SETTING AND PARTICIPANTS: We used Danish nationwide registers of hospitalizations and prescriptions to identify all women admitted with myocardial infarction in the period 1997 to 2009 and with no known diagnosis of AF. Their use of overall HRT and HRT categories was assessed. Multivariable Cox proportional hazards analysis was used to calculate the risk of new-onset AF first year after discharge, comparing use of HRT to no use. MAIN OUTCOME MEASURES: New-onset atrial fibrillation. RESULTS: In the period 1997 to 2009, 32 925 women were discharged alive after MI. In the first year after MI, new-onset AF was diagnosed in 1381 women (4.2%). Unadjusted incidence rates of AF decreased with use of HRT (incidence rate 37.4 for use of overall HRT and 53.7 for no use). Overall HRT was associated with a decreased risk of AF (HR 0.82, 95% confidence interval [CI] 0.68-1.00). The lowest risk of AF was found in women ≥80 years old for use of overall HRT and vaginal estrogen (HR 0.63, CI 0.42-0.94, and HR 0.58, CI 0.34-0.99, respectively). Decreased risk of AF with use of overall HRT and HRT categories was also found in other age groups. CONCLUSIONS: Use of HRT is associated with a decreased risk of new-onset AF in women with myocardial infarction first year after discharge. The underlying mechanisms remain to be determined. Unmeasured confounding might be one of them.

Increased short-term risk of thrombo-embolism or death after interruption of warfarin treatment in patients with atrial fibrillation.

AIMS: It is presently unknown whether patients with atrial fibrillation (AF) are at increased risk of thrombo-embolic adverse events after interruption of warfarin treatment. The purpose of this study was to assess the risk and timing of thrombo-embolism after warfarin treatment interruption. METHODS AND RESULTS: A retrospective, nationwide cohort study of all patients in Denmark treated with warfarin after a first hospitalization with AF in the period 1997-2008. Incidence rate ratios (IRRs) of thrombo-embolic events and all-cause mortality were calculated using the Poisson regression analyses. In total, 48 989 AF patients receiving warfarin treatment were included. Of these, 35 396 patients had at least one episode of warfarin treatment interruption. In all, 8255 deaths or thrombo-embolic events occurred during treatment interruption showing an initial clustering of events with 2717, 835, 500, and 427 events occurring during 0-90, 91-180, 181-270, and 271-360 days after treatment interruption, respectively. Correspondingly, the crude incidence rates were 31.6, 17.7, 12.3, and 11.4 events per 100 patient-years. In a multivariable analysis, the first 90-day interval of treatment interruption was associated with a markedly higher risk of death or thrombo-embolism (IRR 2.5; 95% confidence interval 2.3-2.8) vs. the interval of 271-360 days. CONCLUSION: In patients with AF, an interruption of warfarin treatment is associated with a significantly increased short-term risk of death or thrombo-embolic events within the first 90 days of treatment interruption.

Psoriasis carries an increased risk of venous thromboembolism: a Danish nationwide cohort study.

BACKGROUND: Psoriasis is an immunoinflammatory disease associated with cardiovascular risk factors, atherothrombotic events, and hypercoagulability. Venous thromboembolism (VTE) is potentially lethal and shares risk factors with psoriasis, but the risk of VTE associated with psoriasis is unknown. The present study investigated the potential association between psoriasis and VTE. METHODS AND FINDINGS: Information from nationwide prospectively recorded registers of hospitalization, drug dispensing from pharmacies, socio-economic data, and causes of death was linked on an individual level. In an unselected nationwide cohort, we used multivariate Poisson regression models controlling for age, gender, comorbidity, concomitant medication, socio-economic data, and calendar year, to assess the risk of VTE associated with psoriasis. A total of 35,138 patients with mild and 3,526 patients with severe psoriasis were identified and compared with 4,126,075 controls. Patients with psoriasis had higher incidence rates per 1000 person-years of VTE than controls (1.29, 1.92, and 3.20 for controls, mild psoriasis, and severe psoriasis, respectively). The rate ratio (RR) of VTE was elevated in all patients with psoriasis with RR 1.35 (95% confidence interval [CI] 1.21-1.49) and RR 2.06 (CI 1.63-2.61) for mild and severe psoriasis, respectively. Exclusion of patients with malignancies, and censoring of patients undergoing surgery did not alter the results. CONCLUSION: This nationwide cohort study indicates that patients with psoriasis are at increased risk of VTE. The risk was highest in young patients with severe psoriasis. Physicians should be aware that patients with psoriasis may be at increased risk of both venous and arterial thromboembolic events.

Use and discontinuation of hormone replacement therapy in women with myocardial infarction: a nationwide study.

WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT: General use of hormone replacement therapy (HRT) dropped drastically after 2002 when pivotal randomized trials showed increased risk of coronary artery disease and other complications with HRT. HRT is not recommended for primary or secondary prevention of coronary heart disease and guidelines recommend discontinuation of HRT after myocardial infarction (MI). It is unknown whether women actually discontinue HRT after MI. WHAT THIS STUDY ADDS: Women who use HRT when they experience their MI generally continue using HRT. We found a remarkably low increase in discontinuation after 2002, in contrast to the general drop in use of HRT. AIM: To characterize the pattern of use and discontinuation of postmenopausal hormone replacement therapy (HRT) in women with myocardial infarction (MI) before and after 2002, where the general use of HRT dropped drastically subsequent to the results of the Women's Health Initiative trial. METHODS: All Danish women aged ≥40 years hospitalized with MI in the period 1997 to 2005 and their use of HRT were identified by individual-level-linkage of nationwide registers of hospitalization and drug dispensing from pharmacies. Characteristics associated with HRT use at time of MI and subsequent HRT discontinuation were analysed by multivariable logistic regression. RESULTS: In the study period, 34,778 women were discharged after MI. Of these, 3979 (11.4%) received HRT at the time of MI and their most used categories of HRT were vaginal oestrogen and oral oestrogen alone (46.6% and 28.7%, respectively). The percentage of women who continued HRT during the first year after discharge was 85.0% in the period 2000-2002 and had decreased to 79.6% in the period 2003-2005. Vaginal oestrogen use was associated with overall discontinuation of HRT (odds ratio [OR] 1.37, 95% confidence interval [CI] 1.10, 1.72), whereas use of oral oestrogen alone and use of oral cyclic combined oestrogen/progestogen were associated with change of HRT after MI (OR 2.33, 95% CI 1.10, 4.93 and OR 2.94, 95% CI 1.35, 6.39, respectively). CONCLUSION: The majority of women experiencing an MI during ongoing HRT continued HRT after discharge and this pattern of HRT use did not change markedly after 2002.

Increased mortality associated with low use of clopidogrel in patients with heart failure and acute myocardial infarction not undergoing percutaneous coronary intervention: a nationwide study.

OBJECTIVES: We studied the association of clopidogrel with mortality in acute myocardial infarction (AMI) patients with heart failure (HF) not receiving percutaneous coronary intervention (PCI). BACKGROUND: Use of clopidogrel after AMI is low in patients with HF, despite the fact that clopidogrel is associated with absolute mortality reduction in AMI patients. METHODS: All patients hospitalized with first-time AMI (2000 through 2005) and not undergoing PCI within 30 days from discharge were identified in national registers. Patients with HF treated with clopidogrel were matched by propensity score with patients not treated with clopidogrel. Similarly, 2 groups without HF were identified. Risks of all-cause death were obtained by the Kaplan-Meier method and Cox regression analyses. RESULTS: We identified 56,944 patients with first-time AMI. In the matched cohort with HF (n = 5,050) and a mean follow-up of 1.50 years (SD = 1.2), 709 (28.1%) and 812 (32.2%) deaths occurred in patients receiving and not receiving clopidogrel treatment, respectively (p = 0.002). The corresponding numbers for patients without HF (n = 6,092), with a mean follow-up of 2.05 years (SD = 1.3), were 285 (9.4%) and 294 (9.7%), respectively (p = 0.83). Patients with HF receiving clopidogrel demonstrated reduced mortality (hazard ratio: 0.86; 95% confidence interval: 0.78 to 0.95) compared with patients with HF not receiving clopidogrel. No difference was observed among patients without HF (hazard ratio: 0.98; 95% confidence interval: 0.83 to 1.16). CONCLUSIONS: Clopidogrel was associated with reduced mortality in patients with HF who do not undergo PCI after their first-time AMI, whereas this association was not apparent in patients without HF. Further studies of the benefit of clopidogrel in patients with HF and AMI are warranted.

Prognosis in heart failure and the value of {beta}-blockers are altered by the use of antidepressants and depend on the type of antidepressants used.

BACKGROUND: Depression worsens the prognosis in patients with cardiac disease, and treatment with antidepressants may improve survival. Guidelines recommend use of selective serotonin reuptake inhibitors (SSRIs), but knowledge of the prognostic effect of different classes of antidepressants is sparse. METHODS AND RESULTS: We studied 99 335 patients surviving first hospitalization for heart failure (HF) from 1997 to 2005. Use of HF medication and antidepressants (divided into tricyclic antidepressants [TCA] and SSRI) was determined by prescription claims. Risk of overall and cardiovascular death associated with antidepressants, HF medication, and coadministration of these 2 drug classes was estimated by Cox proportional hazard analyses. Propensity adjusted models were performed as sensitivity analysis. During the study period, there were 53 988 deaths, of which 83.0% were due to cardiovascular causes (median follow-up, 1.9 years; 5, 95% fractiles, 0.04 to 7.06 years). Use of beta-blockers was associated with decreased risk of cardiovascular death (hazard ratio [HR], 0.77; 95% CI, 0.75 to 0.79). Antidepressants were prescribed to 19 411 patients, and both TCA and SSRI were associated with increased risk of overall and cardiovascular death (TCA: HR, 1.33; CI, 1.26 to 1.40; and HR, 1.25; CI, 1.17 to 1.32; SSRI: HR, 1.37; CI, 1.34 to 1.40; and HR, 1.34; CI, 1.30 to 1.38, respectively). Coadministration of SSRI and beta-blockers was associated with a higher risk of overall and cardiovascular death compared with coadministration of beta-blockers and TCA (P for interaction <0.01). CONCLUSIONS: Use of antidepressants in patients with HF was associated with worse prognosis. Coadministration of SSRIs and beta-blockers was associated with increased risk of overall death and cardiovascular death compared with coadministration of TCAs and beta-blockers. To further clarify this, clinical trials testing the optimal antidepressant strategy in patients with HF are warranted.

[Peripartum cardiomyopathy]. / Peripartum kardiomyopati.

Peripartum cardiomyopathy is a rare and potentially fatal disease with peripartum heart failure in previously healthy women. A brief review of the literature is provided with emphasis on recent data indicating that an antiangiogenic cleavage product of prolactin contributes to the molecular mechanisms underlying peripartum cardiomyopathy, and that blocking the release of prolactin with bromocriptine can ameliorate the condition.
