- 2016
-
In: Diabetes & vascular disease research. - : SAGE Publications. - 1752-8984 .- 1479-1641. ; 13:4, s. 307-311

Journal article (peer-reviewed)abstract
- To investigate whether sitagliptin affects copeptin and osmolality, suggesting arginine vasopressin activation and a potential for fluid retention, compared with placebo, in patients with a recent acute coronary syndrome and newly discovered type 2 diabetes or impaired glucose tolerance. A second aim was to confirm whether copeptin correlated with insulin-like growth factor binding protein-1. Methods: Fasting blood samples were used from the BEta-cell function in Glucose abnormalities and Acute Myocardial Infarction trial, in which patients recently hospitalized due to acute coronary syndrome and with newly detected abnormal glucose tolerance were randomized to sitagliptin 100 mg once daily ( n = 34) or placebo ( n = 37). Copeptin, osmolality and insulin-like growth factor binding protein-1 were analysed at baseline and after 12 weeks. Results: Copeptin and osmolality were unaffected by sitagliptin. There was no correlation between copeptin and insulin-like growth factor binding protein-1. Conclusion: Sitagliptin therapy does not appear to be related to activation of the arginine vasopressin system.

Lifestyle and impact on cardiovascular risk factor control in coronary patients across 27 countries: Results from the European Society of Cardiology ESC-EORP EUROASPIRE V registry
- 2019
-
In: European journal of preventive cardiology. - : Oxford University Press (OUP). - 2047-4881 .- 2047-4873. ; 26:8, s. 824-835

Journal article (peer-reviewed)abstract
- The aim of this study was to determine whether the Joint European Societies guidelines on secondary cardiovascular prevention are followed in everyday practice. Design A cross-sectional ESC-EORP survey (EUROASPIRE V) at 131 centres in 81 regions in 27 countries. Methods Patients (<80 years old) with verified coronary artery events or interventions were interviewed and examined ≥6 months later. Results A total of 8261 patients (females 26%) were interviewed. Nineteen per cent smoked and 55% of them were persistent smokers, 38% were obese (body mass index ≥30 kg/m2), 59% were centrally obese (waist circumference: men ≥102 cm; women ≥88 cm) while 66% were physically active <30 min 5 times/week. Forty-two per cent had a blood pressure ≥140/90 mmHg (≥140/85 if diabetic), 71% had low-density lipoprotein cholesterol ≥1.8 mmol/L (≥70 mg/dL) and 29% reported having diabetes. Cardioprotective medication was: anti-platelets 93%, beta-blockers 81%, angiotensin-converting enzyme inhibitors/angiotensin receptor blockers 75% and statins 80%. Conclusion A large majority of coronary patients have unhealthy lifestyles in terms of smoking, diet and sedentary behaviour, which adversely impacts major cardiovascular risk factors. A majority did not achieve their blood pressure, low-density lipoprotein cholesterol and glucose targets. Cardiovascular prevention requires modern preventive cardiology programmes delivered by interdisciplinary teams of healthcare professionals addressing all aspects of lifestyle and risk factor management, in order to reduce the risk of recurrent cardiovascular events.

Adipose lipid turnover and long-term changes in body weight
- 2019
-
In: Nature Medicine. - : Springer Science and Business Media LLC. - 1078-8956 .- 1546-170X. ; 25:9, s. 1385-1389
-
Journal article (peer-reviewed)abstract
- The worldwide obesity epidemic(1) makes it important to understand how lipid turnover (the capacity to store and remove lipids) regulates adipose tissue mass. Cross-sectional studies have shown that excess body fat is associated with decreased adipose lipid removal rates(2,3). Whether lipid turnover is constant over the life span or changes during long-term weight increase or loss is unknown. We determined the turnover of fat cell lipids in adults followed for up to 16 years, by measuring the incorporation of nuclear bomb test-derived C-14 in adipose tissue triglycerides. Lipid removal rate decreases during aging, with a failure to reciprocally adjust the rate of lipid uptake resulting in weight gain. Substantial weight loss is not driven by changes in lipid removal but by the rate of lipid uptake in adipose tissue. Furthermore, individuals with a low baseline lipid removal rate are more likely to remain weight-stable after weight loss. Therefore, lipid turnover adaptation might be important for maintaining pronounced weight loss. Together these findings identify adipose lipid turnover as an important factor for the long-term development of overweight/obesity and weight loss maintenance in humans.

Risk and management of pre-diabetes
- 2019
-
In: European journal of preventive cardiology. - : Oxford University Press (OUP). - 2047-4881 .- 2047-4873. ; 26:2_SUPPL2_suppl, s. 47-54
-
Journal article (peer-reviewed)abstract
- Type 2 diabetes mellitus (T2DM) is associated with a two- to four-fold increased risk of developing cardiovascular disease (CVD) and microvascular complications, which may already be present before diagnosis. It is, therefore, important to detect people with an increased risk of T2DM at an early stage. In order to identify individuals with so-called ‘pre-diabetes’, comprising impaired fasting glucose (IFG) and impaired glucose tolerance (IGT), current guidelines have developed definitions based on fasting plasma glucose, two-hour glucose concentrations and haemoglobin A1c. Subjects with pre-diabetes are at an increased risk of developing T2DM and CVD. This elevated risk seems similar according to the different criteria used to define pre-diabetes. The risk of progression to T2DM or CVD does, however, depend on other risk factors such as sex, body mass index and ethnicity. Based on the risk factors to develop T2DM, many risk assessment models have been developed to identify those at highest risk. These models perform well to identify those at risk and could be used to initiate preventive interventions. Many studies have shown that lifestyle modification and metformin are effective in preventing the development of T2DM, although lifestyle modification seems to have a more sustainable effect. In addition, lifestyle modification seems more effective in those with IGT than those with IFG. In this review, we will describe the different definitions used to define pre-diabetes, progression from pre-diabetes to T2DM or other vascular complications, risk factors associated with progressions and the management of progression to T2DM, ending with clinical recommendations.

Glucose-lowering therapies in patients with type 2 diabetes and cardiovascular diseases
- 2019
-
In: European journal of preventive cardiology. - : Oxford University Press (OUP). - 2047-4881 .- 2047-4873. ; 26:2_SUPPL2_suppl, s. 73-80
-
Journal article (peer-reviewed)abstract
- Type 2 diabetes mellitus is a major risk factor for developing cardiovascular disease, and many patients with diabetes have prevalent cardiovascular complications. Recent cardiovascular outcome clinical trials suggest that certain new glucose-lowering drugs are accompanied by additional cardioprotective properties. Indeed, selected glucagon-like peptide-1 receptor agonists have a proved cardiovascular benefit in terms of a reduced incidence of ischaemic events, while sodium/glucose co-transporter-2 inhibitors have also shown significant protection, with a striking effect on heart failure and renal endpoints. These findings have been integrated in recent guidelines which now recommend prescribing (when initial metformin monotherapy fails) a glucagon-like peptide-1 receptor agonist or a sodium/glucose co-transporter-2 inhibitor with clinical trial-confirmed benefit in patients with diabetes and atherosclerotic cardiovascular disease, and a sodium/glucose co-transporter-2 inhibitor in such patients with heart failure or chronic kidney disease at initial stages. Furthermore, the new 2019 European Society of Cardiology guidelines in collaboration with the European Association for the Study of Diabetes recommend a glucagon-like peptide-1 receptor agonist or a sodium/glucose co-transporter-2 inhibitor in treatment-naive patients with type 2 diabetes mellitus with pre-existing cardiovascular disease or at high cardiovascular risk. Future research will disentangle the mechanisms underpinning these beneficial effects and will also establish to what extent these results are generalisable to the whole diabetes population. In the meantime, available evidence should prompt a wide diffusion of these two classes of drugs among patients with diabetes and cardiovascular disease. Here, we briefly summarise recent findings emerging from cardiovascular outcome clinical trials, discuss their impact on treatment algorithms and propose new possible approaches to improve our knowledge further regarding the cardiovascular effect of glucose-lowering medications.

Elevated levels of adipokines predict outcome after acute myocardial infarction : A long-term follow-up of the Glucose Tolerance in Patients with Acute Myocardial Infarction cohort
- 2017
-
In: Diabetes & Vascular Disease Research. - : Sage Publications. - 1479-1641 .- 1752-8984. ; 14:2, s. 77-87
-
Journal article (peer-reviewed)abstract
- Objective: Adiponectin and leptin are associated with insulin resistance and cardiovascular disease. Information on the prognostic value after an acute myocardial infarction is still conflicting. Methods: Patients (n = 180) without known diabetes and with admission glucose of <11 mmol/L admitted for an acute myocardial infarction in 1998-2000 were followed for mortality and cardiovascular events (first of cardiovascular mortality/acute myocardial infarction/stroke/heart failure) until the end of 2011 (median: 11.6 years). Plasma adiponectin and leptin were related to outcome in Cox proportional-hazard regression analyses. Results: Median age was 64 years and 69% were male. Total mortality was 34% (n = 61) and 44% (n = 80) experienced a cardiovascular event. Adiponectin at discharge predicted cardiovascular events (hazard ratio; 95% confidence interval; 1.45; 1.02-2.07, p = 0.038), total mortality (2.53; 1.64-3.91, p < 0.001) and cancer mortality (3.64; 1.51-8.74, p = 0.004). After adjustment for age, sex, body mass index, previous myocardial infarction and heart failure, adiponectin predicted total mortality (1.79; 1.07-3.00, p = 0.027) but not cardiovascular events. High levels of leptin were associated with cardiovascular events during the first 7 years, after which the association was attenuated. Leptin did not predict total mortality. Conclusion: In patients with acute myocardial infarction but without previously known diabetes, high levels of adiponectin at discharge predicted total mortality. The present results support the hypothesis that high rather than low levels of adiponectin predict mortality after acute myocardial infarction.

Journal article (peer-reviewed)abstract
- Objective: To investigate the long-term prognostic value of insulin-like growth factor-binding protein 1 in patients with acute myocardial infarction. Methods: Patients (n = 180) with admission glucose < 11 mmol/L without previously known diabetes admitted for an acute myocardial infarction in 1998–2000 were followed for mortality and cardiovascular events (first of cardiovascular mortality/acute myocardial infarction/stroke/severe heart failure) until the end of 2011 (median 11.6 years). Fasting levels of insulin-like growth factor-binding protein 1 at day 2 were related to outcome in Cox proportional hazard regression analyses. Results: Median age was 64 years, 69% were male and median insulin-like growth factor-binding protein 1 was 20 µg/L. Total mortality was 34% (n = 61) and 44% (n = 80) experienced a cardiovascular event during a median follow-up time of 11.6 years. After age adjustment, insulin-like growth factor-binding protein 1 was associated with all-cause (1.40; 1.02–1.93, p = 0.039) and cancer mortality (2.09; 1.15–3.79, p = 0.015) but not with cardiovascular death (p = 0.29) or cardiovascular events (p = 0.57). After adjustments also for previous myocardial infarction, previous heart failure and body mass index, insulin-like growth factor-binding protein 1 was still associated with all-cause mortality (1.38; 1.01–1.89, p = 0.046). Conclusion: In patients with acute myocardial infarction without previously known diabetes, high insulin-like growth factor-binding protein 1 was associated with long-term all-cause and cancer mortality but not with cardiovascular events.

Risk factor reduction in type 2 diabetes demands a multifactorial approach
- 2019
-
In: European journal of preventive cardiology. - : Oxford University Press (OUP). - 2047-4881 .- 2047-4873. ; 26:2_SUPPL2_suppl, s. 81-91

Journal article (peer-reviewed)abstract
- Dysglycaemia (i.e. type 2 diabetes mellitus or impaired glucose tolerance) is not only common in patients with cardiovascular disease but increases the risk for future cardiovascular complications. Hyperglycaemia, the hallmark of diabetes, has since long been considered to be the link between diabetes and cardiovascular disease. Diabetes is, however, a complex, multifactorial disorder to which, for example, insulin resistance, endothelial dysfunction and factors such as increased thrombogenicity, hypertension and dyslipidaemia contribute. Thus, treatment needs to be multifactorial and to take cardiovascular aspects into account. Life-style adjustments are, together with blood pressure, lipid and glucose control, important parts of such management. Recent trial data reveal a beneficial effect on cardiovascular prognosis and mortality of blood glucose lowering agents belonging to the classes: sodium-glucose-transporter 2 inhibitors and glucagon-like peptide 1 agonists. The precise mechanisms by which certain sodium-glucose-transporter 2 inhibitors and glucagon-like peptide receptor agonists lead to these beneficial effects are only partly understood. An important impact of the benefits of sodium-glucose-transporter 2 inhibitors is a reduction in heart failure while glucagon-like peptide receptor agonists may retard the development of atherosclerotic vascular disease or stabilising plaques. Although there has been a considerable improvement in the prognosis for people with atherosclerotic diseases over the last decades there is still a gap between those with dysglycaemia, who are at higher risk, than those without dysglycaemia. This residual risk is reasonably related to two major factors: a demand for improved management and a need for new and improved therapeutic opportunities of type 2 diabetes, both routes to an improved prognosis that are at hands. This review is a comprehensive description of the possibilities to improve the prognosis for patients with dysglycaemia by a multifactorial management according to the most recent European guidelines issued in 2019 by the European Society of Cardiology in collaboration with the European Association for the Study of Diabetes.

Transplanted Bone Marrow-Derived Cells Contribute to Human Adipogenesis
- 2015
-
In: Cell Metabolism. - : Elsevier BV. - 1550-4131 .- 1932-7420. ; 22:3, s. 408-417
-
Journal article (peer-reviewed)abstract
- Because human white adipocytes display a high turnover throughout adulthood, a continuous supply of precursor cells is required to maintain adipogenesis. Bone marrow (BM)-derived progenitor cells may contribute to mammalian adipogenesis; however, results in animal models are conflicting. Here we demonstrate in 65 subjects who underwent allogeneic BM or peripheral blood stem cell (PBSC) transplantation that, over the entire lifespan, BM/PBSC-derived progenitor cells contribute similar to 10% to the subcutaneous adipocyte population. While this is independent of gender, age, and different transplantation-related parameters, body fat mass exerts a strong influence, with up to 2.5-fold increased donor cell contribution in obese individuals. Exome and whole-genome sequencing of single adipocytes suggests that BM/PBSC-derived progenitors contribute to adipose tissue via both differentiation and cell fusion. Thus, at least in the setting of transplantation, BM serves as a reservoir for adipocyte progenitors, particularly in obese subjects.

Adiponectin, Free Fatty Acids, and Cardiovascular Outcomes in Patients With Type 2 Diabetes and Acute Coronary Syndrome
- 2018
-
In: Diabetes Care. - : American Diabetes Association. - 0149-5992 .- 1935-5548. ; 41:8, s. 1792-1800
-
Journal article (peer-reviewed)abstract
- OBJECTIVE In observational cohorts, adiponectin is inversely associated and free fatty acids (FFAs) are directly associated with incident coronary heart disease (CHD). Adiponectin tends to be reduced and FFAs elevated in type 2 diabetes. We investigated relationships of adiponectin and FFA and major adverse cardiovascular events (MACEs) and death in patients with acute coronary syndrome (ACS) and type 2 diabetes using data from the AleCardio (Effect of Aleglitazar on Cardiovascular Outcomes After Acute Coronary Syndrome in Patients With Type 2 Diabetes Mellitus) trial, which compared the PPAR-alpha/gamma agonist aleglitazar with placebo. Using Cox regression adjusted for demographic, laboratory, and treatment variables, we determined associations of baseline adiponectin and FFAs, or the change in adiponectin and FFAs from baseline, with MACEs (cardiovascular death, myocardial infarction, or stroke) and death. A twofold higher baseline adiponectin (n = 6,998) was directly associated with risk of MACEs (hazard ratio [HR] 1.17 [95% CI 1.08-1.27]) and death (HR 1.53 [95% CI 1.35-1.73]). A doubling of adiponectin from baseline to month 3 (n = 6,325) was also associated with risk of death (HR 1.20 [95% CI 1.03-1.41]). Baseline FFAs (n = 7,038), but not change in FFAs from baseline (n = 6,365), were directly associated with greater risk of MACEs and death. There were no interactions with study treatment. In contrast to prior observational data for incident CHD, adiponectin is prospectively associated with MACEs and death in patients with type 2 diabetes and ACS, and an increase in adiponectin from baseline is directly related to death. These findings raise the possibility that adiponectin has different effects in patients with type 2 diabetes and ACS than in populations without prevalent cardiovascular disease. Consistent with prior data, FFAs are directly associated with adverse outcomes.

Effectiveness of different outreach strategies to identify individuals at high risk of diabetes in a heterogeneous population: a study in the Swedish municipality of Södertälje
- 2018
-
In: European journal of preventive cardiology. - : Oxford University Press (OUP). - 2047-4881 .- 2047-4873. ; 25:18, s. 1990-1999

Journal article (peer-reviewed)abstract
- Identifying type 2 diabetes mellitus (T2DM) is a prerequisite for the institution of preventive measures to reduce future micro and macrovascular complications. Approximately 50% of people with T2DM are undiagnosed, challenging the assumption that a traditional primary healthcare setting is the most efficient way to reach people at risk of T2DM. A setting of this kind may be even more suboptimal when it comes to reaching immigrants, who often appear to have inferior access to healthcare and/or are less likely to attend routine health checks at primary healthcare centres. Objectives The objective of this study was to identify the best strategy to reach individuals at high risk of T2DM and thereby cardiovascular disease in a heterogeneous population. Methods All 18–65-year-old inhabitants in the Swedish municipality of Södertälje ( n∼51,000) without known T2DM and cardiovascular disease were encouraged to complete the Finnish Diabetes Risk Score (FINDRISC: score > 15 indicating a high and > 20 a very high risk of future T2DM and cardiovascular disease) through the following communication channels: primary care centres, workplaces, Syrian orthodox churches, pharmacies, crowded public places, mass media, social media and mail. Data collection lasted for six weeks. Results The highest response rate was obtained through workplaces (27%) and the largest proportion of respondents at high/very high risk through the Syrian orthodox churches (18%). The proportion reached through primary care centres was 4%, of whom 5% were at elevated risk. The cost of identifying a person at elevated risk through the Syrian orthodox church was €104 compared with €8 through workplaces and €112 through primary care centres. Conclusions The choice of communication channels was important to reach high/very high-risk individuals for T2DM and for screening costs. In this immigrant-dense community, primary care centres were inferior to strategies using workplaces and churches in terms of both the proportion of identified at-risk individuals and costs.

Exploring the insulin secretory properties of the PGD(2)-GPR44/DP2 axis in vitro and in a randomized phase-1 trial of type 2 diabetes patients
- 2018
-
In: PLoS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 13:12
-
Journal article (peer-reviewed)abstract
- Aims/Hypothesis GPR44 (DP2, PTGDR2, CRTh2) is the receptor for the pro-inflammatory mediator prosta-glandin D-2 (PGD(2)) and it is enriched in human islets. In rodent islets, PGD(2) is produced in response to glucose, suggesting that the PGD(2)-GPR44/DP2 axis may play a role in human islet function during hyperglycemia. Consequently, the aim of this work was to elucidate the insulinotropic role of GPR44 antagonism in vitro in human beta-cells and in type 2 diabetes (T2DM) patients. We determined the drive on PGD(2) secretion by glucose and IL-1 beta, as well as, the impact on insulin secretion by pharmacological GPR44/DP2 antagonism (AZD1981) in human islets and beta-cells in vitro. To test if metabolic control would be improved by antagonizing a hyperglycemia-driven increased PGD(2) tone, we performed a proof-of-mechanism study in 20 T2DM patients (average 54 years, HbA1c 9.4%, BMI 31.6 kg/m(2)). The randomized, double-blind, placebo-controlled cross-over study consisted of two three-day treatment periods (AZD1981 or placebo) separated by a three-day wash-out period. Mixed meal tolerance test (MMTT) and intravenous graded glucose infusion (GGI) was performed at start and end of each treatment period. Assessment of AZD1981 pharmacokinetics, glucose, insulin, C-peptide, glucagon, GLP-1, and PGD(2) pathway biomarkers were performed. We found (1) that PGD(2) is produced in human islet in response to high glucose or IL-1 beta, but likely by stellate cells rather than endocrine cells; (2) that PGD(2) suppresses both glucose and GLP-1 induced insulin secretion in vitro; and (3) that the GPR44/DP2 antagonist (AZD1981) in human beta-cells normalizes insulin secretion. However, AZD1981 had no impact on neither glucose nor incretin dependent insulin secretion in humans (GGI AUC (C-peptide 1-2h) and MMTT AUC (Glucose 0-4h) LS mean ratios vs placebo of 0.94 (80% CI of 0.90-0.98, p = 0.12) and 0.99 (90% CI of 0.94-1.05, p = 0.45), despite reaching the expected antagonist exposure. Pharmacological inhibition of the PGD(2)-GPR44/DP2 axis has no major impact on the modulation of acute insulin secretion in T2DM patients.

In: European Heart Journal. - Barcelona, Spain. - 0195-668X .- 1522-9645. ; 38:suppl_1, s. 863-864

Journal article (other academic/artistic)abstract
- Background: A subset of patients with myocardial infarction (MI) has minimal or no symptoms, i.e. clinically unrecognized MI (UMI). Copeptin, a marker of vasopressin, predicts cardiovascular events (CVE).Purpose: To investigate the prognostic implication of copeptin in people with or without MI and to study whether it differs between UMI and recognized MI (RMI).Methods: Copeptin was measured in 926 participants (age 76.0; male 48.5%) in the observational ICELAND MI study. At baseline 246 patients had hospital/surveillance records supporting a RMI (n=91) or myocardial scars detected by magnetic resonance imaging (UMI, n=155). Cox proportional hazard regression was used to assess the prognostic capability of (log) copeptin, in the multiple model adjusted for prior heart failure, fasting blood glucose, age groups and creatinine. The primary endpoint was CVE (cardiovascular death/MI/stroke/PCI/CABG) and the secondary endpoint was total mortality during 9.1 years of follow-up.Results: Copeptin levels were significantly higher in participants with compared to those without a MI (8.9 pmol/L vs. 6.4 pmol/L; p<0.01), but did not differ between the subsets with RMI vs. UMI.In the unadjusted analysis CVE:s were predicted by copeptin in the total cohort (HR 1.60; 95% CI 1.17–2.19; p<0.01) but not after adjustments (HR 1.18; 95% CI 0.84–1.65; p=0.33).Total mortality in the total cohort was predicted by copeptin in the unadjusted analysis. The same was found in patients with and without MI as well as in the subset with RMI, however, not in those with UMI. In the adjusted model copeptin remained as a predictor in the total cohort (HR 1.77; 95% CI 1.24–2.51; p<0.01), in all patients with MI (HR 2.20; 95% CI 1.25–3.87; p<0.01), and in those with RMI (HR 5.73; 95% CI 2.13–15.36; p<0.01).Conclusion: Copeptin levels were higher for participants with MI, however no difference was seen for those with RMI or UMI. Copeptin did not remain as a significant predictor for CVE after adjustments while it was an independent predictor for total mortality in patients with MI including the subset with RMI. This implies that copeptin is a general marker of disease rather than a specific marker for cardiovascular disease.

Journal article (peer-reviewed)abstract
- Objective: Insulin resistance has been linked to development and progression of atherosclerosis and is present in most patients with type 2 diabetes. Whether the degree of insulin resistance predicts adverse outcomes in patients with type 2 diabetes and acute coronary syndrome (ACS) is uncertain. Design: The Effect of Aleglitazar on Cardiovascular Outcomes after Acute Coronary Syndrome in Patients with Type 2 Diabetes Mellitus trial compared the peroxisome proliferator-activated receptor-a/g agonist aleglitazar with placebo in patients with type 2 diabetes and recent ACS. In participants not treated with insulin, we determined whether baseline homeostasis model assessment of insulin resistance (HOMA-IR; n = 4303) or the change in HOMA-IR on assigned study treatment (n = 3568) was related to the risk of death or major adverse cardiovascular events (cardiovascular death, myocardial infarction, and stroke) in unadjusted and adjusted models. Because an inverse association of HOMA-IR with N-terminal pro-B-type natriuretic peptide (NT-proBNP) has been described, we specifically examined effects of adjustment for the latter. Results: In unadjusted analysis, twofold higher baseline HOMA-IR was associated with lower risk of death [hazard ratio (HR): 0.79, 95% CI: 0.68 to 0.91, P = 0.002]. Adjustment for 24 standard demographic and clinical variables had minimal effect on this association. However, after further adjustment for NT-proBNP, the association of HOMA-IR with death was no longer present (adjusted HR: 0.99, 95% CI: 0.83 to 1.19, P = 0.94). Baseline HOMA-IR was not associated with major adverse cardiovascular events, nor was the change in HOMA-IR on study treatment associated with death or major adverse cardiovascular events. Conclusions: After accounting for levels of NT-proBNP, insulin resistance assessed by HOMA-IR is not related to the risk of death or major adverse cardiovascular events in patients with type 2 diabetes and ACS.

- Introduction: Detection of circulating tumour cells (CTCs) in peripheral blood has an established prognostic significance in patients with metastatic breast cancer. Change in the number of detected CTCs is also an indication of response to therapy. Characterisation of CTCs could provide easily accessible treatment predictive information of present cancer cells within the patient and could reveal important knowledge about the metastatic process. The aim of this pilot study was to characterize CTCs with regard to both treatment predictive and more experimental markers by analysing the expression of genes associated with breast cancer.Methods: Blood samples from twelve patients with metastatic breast cancer included in the ongoing CTC-MBC study at Lund University, Sweden (Clinical Trials Id. NCT01322893) were analysed in this pilot study. Systemic treatment included endocrine, targeted and chemotherapy regimen. Blood samples were collected before start of 1st line therapy and at four time points. If progression occurred, a new round of samples was taken. CTCs were isolated from whole blood using the commercial kits AdnaTest EMT1/stem cell and AdnaTest EMT2/stem cell (AdnaGen AG, Langenhagen, Germany). With this method, CTCs are captured using antibodies directed against EpCAM and MUC-1 (EMT1-kit) or EpCAM, HER2 and EGFR (EMT2-kit). Gene expression analyses from CTCs at each time point was performed by TATAA Biocenter (Gothenburg, Sweden) using qPCR. 38 breast cancer related genes were analysed including the oestrogen receptor (ESR), HER2, VEGFR2, ALDH1, PI3K, PTEN and TWIST1.Results: Using positive expression of pseudo-markers EpCAM, MUC1 and HER2 as definition of CTCs, 6 of 12 patients were positive for CTCs. However, gene expression of additional markers in potential CTCs suggests complex patterns such as an increase in TWIST1, ALDH1 and SATB1 at time of progression.Conclusions: We present gene expression data from CTCs isolated before and during therapy in metastatic breast cancer patients. This type of characterisation could provide information of importance for treatment response and clinical outcome.Clinical trial identification: NCT01322893, March 24 2011

- Purpose: To evaluate the estrogen receptor coactivator amplified in breast cancer 1 (AIB1) as a prognostic marker, as well as a predictive marker for response to adjuvant tamoxifen and/or aromatase inhibitors, in early estrogen receptor-positive breast cancer. Method: AIB1 was analyzed with immunohistochemistry in tissue microarrays of the Danish subcohort (N = 1396) of the International Breast Cancer Study Group’s trial BIG 1-98 (randomization between adjuvant tamoxifen versus letrozole versus the sequence of the two drugs). Results: Forty-six percent of the tumors had a high AIB1 expression. In line with previous studies, AIB1 correlated to a more aggressive tumor-phenotype (HER2 amplification and a high malignancy grade). High AIB1 also correlated to higher estrogen receptor expression (80–100 vs. 1–79%), and ductal histological type. High AIB1 expression was associated with a poor disease-free survival (univariable: hazard ratio 1.35, 95% confidence interval 1.12–1.63. Multivariable: hazard ratio 1.29, 95% confidence interval 1.06–1.58) and overall survival (univariable: hazard ratio 1.34, 95% confidence interval 1.07–1.68. Multivariable: hazard ratio 1.25, 95% confidence interval 0.99–1.60). HER2 did not seem to modify the prognostic effect of AIB1. No difference in treatment effect between tamoxifen and letrozole in relation to AIB1 was found. Conclusions: In a subset of the large international randomized trial BIG 1-98, we confirm AIB1 to be a strong prognostic factor in early breast cancer. Hence, although tumor AIB1 expression does not seem to be useful for the choice of tamoxifen versus an aromatase inhibitor in postmenopausal endocrine-responsive breast cancer, AIB1 is an interesting target for new anti-cancer therapies and further investigations of this biomarker is warranted.

Journal article (peer-reviewed)abstract
- Patients with peripheral artery disease have an increased risk of cardiovascular morbidity and mortality. Antiplatelet agents are widely used to reduce these complications.This was a multicentre, double-blind, randomised placebo-controlled trial for which patients were recruited at 602 hospitals, clinics, or community practices from 33 countries across six continents. Eligible patients had a history of peripheral artery disease of the lower extremities (previous peripheral bypass surgery or angioplasty, limb or foot amputation, intermittent claudication with objective evidence of peripheral artery disease), of the carotid arteries (previous carotid artery revascularisation or asymptomatic carotid artery stenosis of at least 50%), or coronary artery disease with an ankle-brachial index of less than 0·90. After a 30-day run-in period, patients were randomly assigned (1:1:1) to receive oral rivaroxaban (2·5 mg twice a day) plus aspirin (100 mg once a day), rivaroxaban twice a day (5 mg with aspirin placebo once a day), or to aspirin once a day (100 mg and rivaroxaban placebo twice a day). Randomisation was computer generated. Each treatment group was double dummy, and the patient, investigators, and central study staff were masked to treatment allocation. The primary outcome was cardiovascular death, myocardial infarction or stroke; the primary peripheral artery disease outcome was major adverse limb events including major amputation. This trial is registered with ClinicalTrials.gov, number NCT01776424, and is closed to new participants.Between March 12, 2013, and May 10, 2016, we enrolled 7470 patients with peripheral artery disease from 558 centres. The combination of rivaroxaban plus aspirin compared with aspirin alone reduced the composite endpoint of cardiovascular death, myocardial infarction, or stroke (126 [5%] of 2492 vs 174 [7%] of 2504; hazard ratio [HR] 0·72, 95% CI 0·57-0·90, p=0·0047), and major adverse limb events including major amputation (32 [1%] vs 60 [2%]; HR 0·54 95% CI 0·35-0·82, p=0·0037). Rivaroxaban 5 mg twice a day compared with aspirin alone did not significantly reduce the composite endpoint (149 [6%] of 2474 vs 174 [7%] of 2504; HR 0·86, 95% CI 0·69-1·08, p=0·19), but reduced major adverse limb events including major amputation (40 [2%] vs 60 [2%]; HR 0·67, 95% CI 0·45-1·00, p=0·05). The median duration of treatment was 21 months. The use of the rivaroxaban plus aspirin combination increased major bleeding compared with the aspirin alone group (77 [3%] of 2492 vs 48 [2%] of 2504; HR 1·61, 95% CI 1·12-2·31, p=0·0089), which was mainly gastrointestinal. Similarly, major bleeding occurred in 79 (3%) of 2474 patients with rivaroxaban 5 mg, and in 48 (2%) of 2504 in the aspirin alone group (HR 1·68, 95% CI 1·17-2·40; p=0·0043).Low-dose rivaroxaban taken twice a day plus aspirin once a day reduced major adverse cardiovascular and limb events when compared with aspirin alone. Although major bleeding was increased, fatal or critical organ bleeding was not. This combination therapy represents an important advance in the management of patients with peripheral artery disease. Rivaroxaban alone did not significantly reduce major adverse cardiovascular events compared with asprin alone, but reduced major adverse limb events and increased major bleeding.Bayer AG.

In: European journal of preventive cardiology. - : Oxford University Press (OUP). - 2047-4881 .- 2047-4873. ; 26:2_SUPPL2_suppl, s. 25-32

Journal article (peer-reviewed)abstract
- The global prevalence of diabetes is predicted to increase dramatically in the coming decades as the population grows and ages, in parallel with the rising burden of overweight and obesity, in both developed and developing countries. Cardiovascular disease represents the principal cause of death and morbidity among people with diabetes, especially in those with type 2 diabetes mellitus. Adults with diabetes have 2–4 times increased cardiovascular risk compared with adults without diabetes, and the risk rises with worsening glycaemic control. Diabetes has been associated with 75% increase in mortality rate in adults, and cardiovascular disease accounts for a large part of the excess mortality. Diabetes-related macrovascular and microvascular complications, including coronary heart disease, cerebrovascular disease, heart failure, peripheral vascular disease, chronic renal disease, diabetic retinopathy and cardiovascular autonomic neuropathy are responsible for the impaired quality of life, disability and premature death associated with diabetes. Given the substantial clinical impact of diabetes as a cardiovascular risk factor, there has been a growing focus on diabetes-related complications. While some population-based studies suggest that the epidemiology of such complications is changing and that rates of all-cause and cardiovascular mortality among individuals with diabetes are decreasing in high-income countries, the economic and social burden of diabetes is expected to rise due to changing demographics and lifestyle especially in middle- and low-income countries. In this review we outline data from population-based studies on recent and long-term trends in diabetes-related complications.

A panel of correlates predicts vaccine-induced protection of rats against respiratory challenge with virulent Francisella tularensis
- 2018

Journal article (peer-reviewed)abstract
- There are no defined correlates of protection for any intracellular pathogen, including the bacterium Francisella tularensis, which causes tularemia. Evaluating vaccine efficacy against sporadic diseases like tularemia using field trials is problematic, and therefore alternative strategies to test vaccine candidates like the Francisella Live Vaccine Strain (LVS), such as testing in animals and applying correlate measurements, are needed. Recently, we described a promising correlate strategy that predicted the degree of vaccine-induced protection in mice given parenteral challenges, primarily when using an attenuated Francisella strain. Here, we demonstrate that using peripheral blood lymphocytes (PBLs) in this approach predicts LVS-mediated protection against respiratory challenge of Fischer 344 rats with fully virulent F. tularensis, with exceptional sensitivity and specificity. Rats were vaccinated with a panel of LVS-derived vaccines and subsequently given lethal respiratory challenges with Type A F. tularensis. In parallel, PBLs from vaccinated rats were evaluated for their functional ability to control intramacrophage Francisella growth in in vitro co-culture assays. PBLs recovered from co-cultures were also evaluated for relative gene expression using a large panel of genes identified in murine studies. In vitro control of LVS intramacrophage replication reflected the hierarchy of protection. Further, despite variability between individuals, 22 genes were significantly more up-regulated in PBLs from rats vaccinated with LVS compared to those from rats vaccinated with the variant LVS-R or heat killed LVS, which were poorly protective. These genes included IFN-gamma, IL-21, NOS2, LTA, T-bet, IL-12rβ2, and CCL5. Most importantly, combining quantifications of intramacrophage growth control with 5-7 gene expression levels using multivariate analyses discriminated protected from non-protected individuals with greater than 95% sensitivity and specificity. The results therefore support translation of this approach to non-human primates and people to evaluate new vaccines against Francisella and other intracellular pathogens.

Nomograms for preoperative prediction of axillary nodal status in breast cancer
- 2017
-
In: British Journal of Surgery. - : Oxford University Press (OUP). - 0007-1323 .- 1365-2168. ; 104:11, s. 1494-1505

Journal article (peer-reviewed)abstract
- Background: Axillary staging in patients with breast cancer and clinically node-negative disease is performed by sentinel node biopsy (SLNB). The aim of this study was to integrate feasible preoperative variables into nomograms to guide clinicians in stratifying treatment options into no axillary staging for patients with non-metastatic disease (N0), SLNB for those with one or two metastases, and axillary lymph node dissection (ALND) for patients with three or more metastases. Methods: Patients presenting to Skåne University Hospital, Lund, with breast cancer were included in a prospectively maintained registry between January 2009 and December 2012. Those with a preoperative diagnosis of nodal metastases were excluded. Patients with data on hormone receptor status, human epidermal growth factor receptor 2 and Ki-67 expression were included to allow grouping into surrogate molecular subtypes. Based on logistic regression analyses, nomograms summarizing the strength of the associations between the predictors and each nodal status endpoint were developed. Predictive performance was assessed using the area under the receiver operating characteristic (ROC) curve. Bootstrap resampling was performed for internal validation. Results: Of the 692 patients eligible for analysis, 248 were diagnosed with node-positive disease. Molecular subtype, age, mode of detection, tumour size, multifocality and vascular invasion were identified as predictors of any nodal disease. Nomograms that included these predictors demonstrated good predictive abilities, and comparable performances in the internal validation; the area under the ROC curve was 0·74 for N0 versus any lymph node metastasis, 0·70 for one or two involved nodes versus N0, and 0·81 for at least three nodes versus two or fewer metastatic nodes. Conclusion: The nomograms presented facilitate preoperative decision-making regarding the extent of axillary surgery.

Effects of adjuvant tamoxifen over three decades on breast cancer–free and distant recurrence–free interval among premenopausal women with oestrogen receptor–positive breast cancer randomised in the Swedish SBII:2pre trial
- 2019
-
In: European Journal of Cancer. - : Elsevier BV. - 0959-8049 .- 1879-0852. ; 110, s. 53-61
-
Journal article (peer-reviewed)abstract
- Aims: The primary aim was to compare 2 years of adjuvant tamoxifen versus no systemic treatment in premenopausal patients with oestrogen receptor (ER)–positive tumours, regarding breast cancer–free interval (BCFi) and distant recurrence–free interval (D-RFi), with 30 years of follow-up and for specified intervals. Moreover, we aimed to investigate the effects of adjuvant tamoxifen on the incidence of secondary malignancies and survival after distant recurrence. Methods: Premenopausal patients with primary breast cancer were randomised to 2 years of tamoxifen (n = 277) or no systemic treatment (n = 287), irrespective of ER status. Information regarding events was collected by a review of medical records and from national registers. Results: The median follow-up for all patients without events was 28 years, and only four of the patients alive had a follow-up of <20 years. With 30 years of follow-up, tamoxifen prolonged BCFi in the intention-to-treat population (hazard ratio [HR] = 0.76, 95% confidence interval (CI) 0.61–0.94, p = 0.011) compared with no treatment. In patients with ER-positive tumours (n = 362), tamoxifen prolonged BCFi (HR = 0.62, 95% CI 0.47–0.82, p = 0.001) and D-RFi (HR = 0.73, 95% CI 0.54–0.99, p = 0.043). The positive effect on BCFi was significant also for the interval >15–30 years (HR = 0.53, 95% CI 0.28–0.98, p = 0.042). For patients with ER-positive tumours who were diagnosed with distant recurrence (n = 165), survival after distant recurrence was shorter among tamoxifen-treated patients (median, 29 months versus 43 months). The incidence of contralateral breast cancer was 42% lower in the tamoxifen group (HR = 0.58, 95% CI 0.35–0.96, p = 0.035), whereas no differences were observed regarding other secondary malignancies. Conclusions: With three decades of follow-up, 2 years of adjuvant tamoxifen reduced the incidence of breast cancer–related events and distant recurrence, and the carryover effect seems to extend beyond 15 years. Moreover, adjuvant tamoxifen seems to be associated with shorter survival after diagnosis of distant recurrence.
