- Background In patients with type 2 diabetes and a high cardiovascular risk profile, the sodium-glucose co-transporter-2 (SGLT2) inhibitors empagliflozin and canagliflozin have been shown to lower cardiovascular morbidity and mortality. Using real-world data from clinical practice, we aimed to compare cardiovascular mortality and morbidity in new users of SGLT2 inhibitors versus new users of other glucose-lowering drugs, in a population with a broad cardiovascular risk profile. Methods CVD-REAL Nordic was an observational analysis of individual patient-level data from the Prescribed Drug Registers, Cause of Death Registers, and National Patient Registers in Denmark, Norway, and Sweden. All patients who filled a prescription for glucose-lowering drugs between 2012 and 2015 were included and followed up until Dec 31, 2015. Patients were divided into new users of SGLT2 inhibitors and new users of other glucose-lowering drugs. Each SGLT2 inhibitor user was matched with three users of other glucose-lowering drugs by use of propensity scores. Hazard ratios (HRs) were estimated by country (Cox survival model) and weighted averages were calculated. Cardiovascular outcomes investigated were cardiovascular mortality, major adverse cardiovascular events (cardiovascular mortality, myocardial infarction, and ischaemic or haemorrhagic stroke), hospital events for heart failure (inpatient or outpatient visit with a primary diagnosis of heart failure), non-fatal myocardial infarction, non-fatal stroke, and atrial fibrillation. We also assessed incidence of severe hypoglycaemia. Findings Matched SGLT2 inhibitor (n=22 830) and other glucose-lowering drug (n=68 490) groups were well balanced at baseline, with a mean follow-up of 0.9 (SD 4.1) years (80 669 patient-years) and mean age of 61 (12.0) years; 40% (36 362 of 91 320) were women and prevalence of cardiovascular disease was 25% (22 686 of 91 320). 94% of the total SGLT2 inhibitor exposure time was for use of dapagliflozin, with 5% for empagliflozin, and 1% for canagliflozin. Compared with other glucose-lowering drugs, use of SGLT2 inhibitors was associated with decreased risk of cardiovascular mortality (HR 0.53 [95% CI 0.40-0.71]), major adverse cardiovascular events (0.78 [0.69-0.87]), and hospital events for heart failure (0.70 [0.61-0.81]; p<0.0001 for all). We did not identify significant differences between use of SGLT2 inhibitors and use of other glucose-lowering drugs for non-fatal myocardial infarction, non-fatal stroke, or atrial fibrillation. Compared with other glucose-lowering drugs, use of SGLT2 inhibitors was associated with a decreased risk of severe hypoglycaemia (HR 0.76 [0.65-0.90]; p=0.001). For cardiovascular mortality, the differences were similar for the 25% of individuals with cardiovascular disease at baseline and those without (HR 0.60 [0.42-0.85] vs 0.55 [0.34-0.90]), while for major adverse cardiovascular events the HR in the group with cardiovascular disease at baseline was 0.70 (0.59-0.83) versus 0.90 (0.76-1.07) in the group without. Interpretation In a population of patients with type 2 diabetes and a broad cardiovascular risk profile, SGLT2 inhibitor use was associated with reduced cardiovascular disease and cardiovascular mortality compared with use of other glucose-lowering drugs-a finding consistent with the results of clinical trials in patients at high cardiovascular risk.

- 2010
-
In: British Journal of Nutrition. - 0007-1145 .- 1475-2662. ; 104:2, s. 160-163

Journal article (peer-reviewed)abstract
- Hypertension is a key feature of the metabolic syndrome. Lifestyle and dietary changes may affect blood pressure (BP), but the knowledge of the effects of dietary fat modification in subjects with the metabolic syndrome is limited. The objective of the present study was to investigate the effect of an isoenergetic change in the quantity and quality of dietary fat on BP in subjects with the metabolic syndrome. In a 12-week European multi-centre, parallel, randomised controlled dietary intervention trial (LIPGENE), 486 subjects were assigned to one of the four diets distinct in fat quantity and quality: two high-fat diets rich in saturated fat or monounsaturated fat and two low-fat, high-complex carbohydrate diets with or without 1.2 g/d of very long-chain n-3 PUFA supplementation. There were no overall differences in systolic BP (SBP), diastolic BP or pulse pressure (PP) between the dietary groups after the intervention. The high-fat diet rich in saturated fat had minor unfavourable effects on SBP and PP in males.

- Objective: Impaired insulin secretion and action contribute to the development of type 2 diabetes. Dietary fat modification may improve insulin sensitivity, whereas the effect on insulin secretion is unclear. We investigated the effect of dietary fat modification on insulin secretion in subjects with the metabolic syndrome.Design: In a 12-week pan-European parallel, randomized controlled dietary intervention trial (LIPGENE), 486 subjects were assigned to four isoenergetic diets: high-fat diets rich in saturated fat (HSFA) or monounsaturated fat (HMUFA) or low-fat, high-complex carbohydrate diets with (LFHCC n-3) or without (LFHCC control) 1.2 g/day of n-3 PUFA supplementation. Insulin secretion was estimated as acute insulin response to glucose (AIRg) and disposition index (DI), modeled from an intravenous glucose tolerance test.Results: There were no overall effect of the dietary intervention on AIRg and DI in the total cohort, in neither the highfat nor LFHCC groups. We observed significant diet*fasting glucose category interactions for AIRg (P = 0.021) and DI (P = 0.001) in the high-fat groups. In subjects with normal fasting glucose and preserved first phase insulin secretion, the HMUFA diet increased, whereas the HSFA diet reduced AIRg (P = 0.015) and DI (P = 0.010).Conclusions: The effects of dietary fat modification on insulin secretion were minor, and only evident in normoglycemic subjects. In this case, the HMUFA diet improved AIRg and DI, as compared to the HSFA diet.

Serum Vitamin D Concentration Does Not Predict Insulin Action or Secretion in European Subjects With the Metabolic Syndrome
- 2010
-
In: Diabetes Care. - : American Diabetes Association. - 0149-5992 .- 1935-5548. ; 33:4, s. 923-925

Journal article (peer-reviewed)abstract
- OBJECTIVE To investigate the relation between serum concentration of 25-hydroxyvitamin D [25(OH)D] and insulin action and secretion. RESEARCH DESIGN AND METHODS In a cross-sectional study of 446 Pan-European subjects with the metabolic syndrome, insulin action and secretion were assessed by homeostasis model assessment (HOMA) indexes and intravenous glucose tolerance test to calculate acute insulin response, insulin sensitivity, and disposition index. Serum 25(OH)D was measured by high-performance liquid chromatography/mass spectrometry. RESULTS - The 25(OH)D-3 concentration was 57.1 +/- 26.0 nmol/l (mean +/- SD), and only 20% of the subjects had 25(OH)D-3 levels >= 75 nmol/l. In multiple linear analyses, 25(OH)D-3 concentrations were not associated with parameters of insulin action or secretion after adjustment for BMI and other covariates. CONCLUSIONS In a large sample of subjects with the metabolic syndrome, serum concentrations of 25(OH)D-3 did not predict insulin action or secretion. Clear evidence that D vitamin status directly influences insulin secretion or action is still lacking.

Calpain-10 interacts with plasma saturated fatty acid concentrations to influence insulin resistance in individuals with the metabolic syndrome
- 2011
-
In: American Journal of Clinical Nutrition. - : Elsevier BV. - 0002-9165 .- 1938-3207. ; 93:5, s. 1136-1141
-
Journal article (peer-reviewed)abstract
- Background: Calpain-10 protein (intracellular Ca2+-dependent cysteine protease) may play a role in glucose metabolism, pancreatic beta cell function, and regulation of thermogenesis. Several CAPN10 polymorphic sites have been studied for their potential use as risk markers for type 2 diabetes and the metabolic syndrome (MetS). Fatty acids are key metabolic regulators that may interact with genetic factors and influence glucose metabolism. Objective: The objective was to examine whether the genetic variability at the CAPN10 gene locus is associated with the degree of insulin resistance and plasma fatty acid concentrations in subjects with MetS. Design: The insulin sensitivity index, glucose effectiveness, insulin resistance [homeostasis model assessment of insulin resistance (HOMA-IR)], insulin secretion (disposition index, acute insulin response, and HOMA of beta cell function), plasma fatty acid composition, and 5 CAPN10 single nucleotide polymorphisms (SNPs) were determined in a cross-sectional analysis of 452 subjects with MetS participating in the LIPGENE dietary intervention cohort. Results: The rs2953171 SNP interacted with plasma total saturated fatty acid (SFA) concentrations, which were significantly associated with insulin sensitivity (P < 0.031 for fasting insulin, P < 0.028 for HOMA-IR, and P < 0.012 for glucose effectiveness). The G/G genotype was associated with lower fasting insulin concentrations, lower HOMA-IR, and higher glucose effectiveness in subjects with low SFA concentrations (below the median) than in subjects with the minor A allele (G/A and A/A). In contrast, subjects with the G/G allele with the highest SFA concentrations (above the median) had higher fasting insulin and HOMA-IR values and lower glucose effectiveness than did subjects with the A allele. Conclusion: The rs2953171 polymorphism at the CAPN10 gene locus may influence insulin sensitivity by interacting with the plasma fatty acid composition in subjects with MetS. This trial was registered at clinicaltrials. gov as NCT00429195.

Glucokinase Regulatory Protein Genetic Variant Interacts with Omega-3 PUFA to Influence Insulin Resistance and Inflammation in Metabolic Syndrome
- 2011

In: PLOS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 6:6, s. e20555-
-
Journal article (peer-reviewed)abstract
- Glucokinase Regulatory Protein (GCKR) plays a central role regulating both hepatic triglyceride and glucose metabolism. Fatty acids are key metabolic regulators, which interact with genetic factors and influence glucose metabolism and other metabolic traits. Omega-3 polyunsaturated fatty acids (n-3 PUFA) have been of considerable interest, due to their potential to reduce metabolic syndrome (MetS) risk. Objective: To examine whether genetic variability at the GCKR gene locus was associated with the degree of insulin resistance, plasma concentrations of C-reactive protein (CRP) and n-3 PUFA in MetS subjects. Design: Homeostasis model assessment of insulin resistance (HOMA-IR), HOMA-B, plasma concentrations of C-peptide, CRP, fatty acid composition and the GCKR rs1260326-P446L polymorphism, were determined in a cross-sectional analysis of 379 subjects with MetS participating in the LIPGENE dietary cohort. Results: Among subjects with n-3 PUFA levels below the population median, carriers of the common C/C genotype had higher plasma concentrations of fasting insulin (P = 0.019), C-peptide (P = 0.004), HOMA-IR (P = 0.008) and CRP (P = 0.032) as compared with subjects carrying the minor T-allele (Leu446). In contrast, homozygous C/C carriers with n-3 PUFA levels above the median showed lower plasma concentrations of fasting insulin, peptide C, HOMA-IR and CRP, as compared with individuals with the T-allele. Conclusions: We have demonstrated a significant interaction between the GCKR rs1260326-P446L polymorphism and plasma n-3 PUFA levels modulating insulin resistance and inflammatory markers in MetS subjects. Further studies are needed to confirm this gene-diet interaction in the general population and whether targeted dietary recommendations can prevent MetS in genetically susceptible individuals.

Journal article (peer-reviewed)abstract
- Scope: Several insulin receptor substrate-2 (IRS-2) polymorphisms have been studied in relation to insulin resistance and type 2 diabetes. To examine whether the genetic variability at the IRS-2 gene locus was associated with the degree of insulin resistance and plasma fatty acid levels in metabolic syndrome (MetS) subjects.Methods and results: Insulin sensitivity, insulin secretion, glucose effectiveness, plasma fatty acid composition and three IRS-2 tag-single nucleotide polymorphisms (SNPs) were determined in 452 MetS subjects. Among subjects with the lowest level of monounsaturated (MUFA) (below the median), the rs2289046 A/A genotype was associated with lower glucose effectiveness (p < 0.038), higher fasting insulin concentrations (p < 0.028) and higher HOMA IR (p < 0.038) as compared to subjects carrying the minor G-allele (A/G and G/G). In contrast, among subjects with the highest level of MUFA (above the median), the A/A genotype was associated with lower fasting insulin concentrations and HOMA-IR, whereas individuals carrying the G allele and with the highest level of omega-3 polyunsaturated fatty acids (above the median) showed lower fasting insulin (p < 0.01) and HOMA-IR (p < 0.02) as compared with A/A subjects.Conclusion: The rs2289046 polymorphism at the IRS2 gene locus may influence insulin sensitivity by interacting with certain plasma fatty acids in MetS subjects.

Journal article (peer-reviewed)abstract
- Aims To compare the sodium-glucose-cotransporter-2 (SGLT-2) inhibitor dapagliflozin with dipeptidyl peptidase-4 (DPP-4) inhibitors with regard to risk associations with major adverse cardiovascular (CV) events (MACE; non-fatal myocardial infarction, non-fatal stroke or cardiovascular mortality), hospitalization for heart failure (HHF), atrial fibrillation and severe hypoglycaemia in patients with type 2 diabetes (T2D) in a real-world setting.Methods All patients with T2D prescribed glucose-lowering drugs (GLDs) during 2012 to 2015 were identified in nationwide registries in Denmark, Norway and Sweden. Patients were divided into two groups: new users of dapagliflozin and new users of DPP-4 inhibitors, matched 1:3 by propensity score, calculated by patient characteristics, comorbidities and drug treatment. Cox survival models were used to estimate hazard ratio (HR) per country separately, and a weighted average was calculated.Results After matching, a total of 40908 patients with T2D were identified as new users of dapagliflozin (n=10227) or a DPP-4 inhibitor (n=30681). The groups were well balanced at baseline; their mean age was 61years and 23% had CV disease. The mean follow-up time was 0.95years, with a total of 38760 patient-years. Dapagliflozin was associated with a lower risk of MACE, HHF and all-cause mortality compared with DPP-4 inhibitors: HRs 0.79 (95% confidence interval [CI] 0.67-0.94), 0.62 (95% CI 0.50-0.77), and 0.59 (95% CI 0.49-0.72), respectively. Numerically lower, but non-significant HRs were observed for myocardial infarction (0.91 [95% CI 0.72-1.16]), stroke (0.79 [95% CI 0.61-1.03]) and CV mortality (0.76 [95% CI 0.53-1.08]) Neutral associations with atrial fibrillation and severe hypoglycaemia were observed.Conclusions Dapagliflozin was associated with lower risks of CV events and all-cause mortality compared with DPP-4 inhibitors in a real-world clinical setting and a broad T2D population.

Different patterns of second-line treatment in type 2 diabetes after metformin monotherapy in Denmark, Finland, Norway and Sweden (D360 Nordic) : A multinational observational study.
- 2018
-
In: Endocrinology, diabetes & metabolism. - : Wiley. - 2398-9238. ; 1:4
-
Journal article (peer-reviewed)abstract
- Aims: The understanding of second-line use of glucose-lowering drugs (GLDs) in the general population with type 2 diabetes (T2D) treatment is important as recent results have shown cardiovascular benefits with sodium-glucose cotransporter-2 inhibitors (SGLT-2i) and glucagon-like peptide-1 receptor agonists (GLP-1RA). Our aim was to describe second-line GLD treatment patterns in four Nordic countries.Methods: All T2D patients treated with GLD between 2006 and 2015 were identified in prescribed drug registries in Denmark, Finland, Norway and Sweden, and linked with National Patient and Cause of Death Registries. Second-line treatment was defined as a prescription of a second GLD class following ≥6 months of metformin monotherapy. Index was the date of first dispense of the second-line drug.Results: A rapid uptake of newer GLDs (GLP-1RA, DPP-4i and SGLT-2i) over the 10-year observation period was seen in Denmark, Finland and Norway, while slower in Sweden. In 2015, 33,880 (3.1%) of 1,078,692 T2D patients initiated second-line treatment, and newer GLDs were more commonly used in Finland (92%), Norway (71%) and Denmark (70%) vs Sweden (44%). In 2015, the use of older GLDs (insulin and sulphonylureas) was 7-fold greater in Sweden compared to Finland (49% vs 7%), and 1.6-fold greater compared with Denmark and Norway (49% vs 30% and 29%, respectively).Conclusions: Despite comparable demography and healthcare systems in four neighbouring countries, surprisingly large differences in second-line use of newer GLDs were found. With recent evidence of potential cardiovascular benefits with newer GLDs, such differences may have an important impact on cardiovascular outcomes.

Effects of dietary fat modification on oxidative stress and inflammatory markers in the LIPGENE study
- 2010
-
In: British Journal of Nutrition. - 0007-1145 .- 1475-2662. ; 104:9, s. 1357-1362
-
Journal article (peer-reviewed)abstract
- Subjects with the metabolic syndrome (MetS) have enhanced oxidative stress and inflammation. Dietary fat quality has been proposed to be implicated in these conditions. We investigated the impact of four diets distinct in fat quantity and quality on 8-iso-PGF2α (a major F2-isoprostane and oxidative stress indicator), 15-keto-13,14-dihydro-PGF2α (15-keto-dihydro-PGF2α, a major PGF2α metabolite and marker of cyclooxygenase-mediated inflammation) and C-reactive protein (CRP). In a 12-week parallel multicentre dietary intervention study (LIPGENE), 417 volunteers with the MetS were randomly assigned to one of the four diets: two high-fat diets (38 % energy (%E)) rich in SFA or MUFA and two low-fat high-complex carbohydrate diets (28 %E) with (LFHCC n-3) or without (LFHCC) 1·24 g/d of very long chain n-3 fatty acid supplementation. Urinary levels of 8-iso-PGF2α and 15-keto-dihydro-PGF2α were determined by RIA and adjusted for urinary creatinine levels. Serum concentration of CRP was measured by ELISA. Neither concentrations of 8-iso-PGF2α and 15-keto-dihydro-PGF2α nor those of CRP differed between diet groups at baseline (P>0·07) or at the end of the study (P>0·44). Also, no differences in changes of the markers were observed between the diet groups (8-iso-PGF2α, P = 0·83; 15-keto-dihydro-PGF2α, P = 0·45; and CRP, P = 0·97). In conclusion, a 12-week dietary fat modification did not affect the investigated markers of oxidative stress and inflammation among subjects with the MetS in the LIPGENE study.
