- AIMS/HYPOTHESIS: The aim of this study of type 2 diabetic patients in the Swedish National Diabetes Register was to study the associations of BMI, overweight (BMI 25-29.9 kg/m(2)) and obesity (BMI >or= 30 kg/m(2)) with cardiovascular disease in type 2 diabetes, as these associations have not previously been clarified. METHODS: Patients aged 30-74 years with no previous CHD or stroke (N = 13,087) were followed for a mean of 5.6 years until 2003 for fatal or non-fatal CHD, stroke, cardiovascular disease (CHD or stroke) and total mortality. In total, 1,922 cardiovascular-disease events occurred, based on 64,864 person-years. RESULTS: The relative risks of CHD, stroke, cardiovascular disease and total mortality for a 5 unit increase in BMI at baseline were 15%, 11%, 13% and 27%, respectively, using Cox regression analysis, after adjusting for age, sex, diabetes duration, hypoglycaemic treatment and smoking (model 1), and were 9%, 4% (not significant), 7% and 20%, respectively, when adjusting also for HbA(1c), blood pressure, antihypertensive drugs, lipid-reducing drugs and microalbuminuria (model 2). Adjusted hazard ratios (model 1) for CHD, cardiovascular disease and total mortality with overweight were 1.27 (95% CI 1.09-1.48), 1.24 (1.09-1.41) and 1.16 (0.94-1.45), respectively, and 1.49 (1.27-1.76), 1.44 (1.26-1.64) and 1.71 (1.36-2.14) with obesity, as compared with normal weight. Significant hazard ratios were attenuated when adjusted according to model 2. For a 1 unit increase in BMI during follow-up, the relative risk of CHD (model 2) was 1.13 (1.04-1.23; p = 0.005). CONCLUSIONS/INTERPRETATION: Both overweight and obesity independently increased the risk of CHD and cardiovascular disease in patients with type 2 diabetes. The CHD risk was higher with increasing BMI than with stable or decreasing BMI during the study.

- AIMS/HYPOTHESIS: Pharmacological augmentation of glucagon-like peptide 1 receptor signalling by dipeptidyl peptidase 4 (DPP-4) inhibition reduced intestinal lipoprotein secretion in experimental studies, suggesting that DPP-4 inhibitors may ameliorate dyslipidaemia and thus reduce cardiovascular risk in patients with type 2 diabetes. We assessed the effects of alogliptin (Alo) and Alo co-administered with pioglitazone (Pio) vs placebo (Pbo) on triacylglycerol (TG)-rich lipoproteins in type 2 diabetes before and following a high-fat meal. METHODS: Seventy-one patients (age 18-70 years), who did not reach HbA(1c) 6.5% (48 mmol/mol) with lifestyle and/or metformin, sulfonylurea or glinide therapy, participated in this 16 week, double-centre (university hospitals) Pbo-controlled parallel-group study. All participants, people doing measurements or examinations, and people assessing the outcomes were blinded to group assignment. Fasting TG 1.7-5.0 mmol/l was among the entry criteria. Patients received a high-fat mixed meal before and 4 and 16 weeks after randomisation (allocation by central office) to Alo (n = 25), Alo/Pio (n = 22) or Pbo (n = 24). Blood was sampled at pre-specified intervals, starting at 15 min before and ending 8 h after meal ingestion. RESULTS: At week 16, Alo (n = 25) and Alo/Pio (n = 21) vs Pbo (n = 24) produced similar significant reductions in total postprandial TG response (incremental AUC [iAUC]; p < 0.001), as well as in chylomicron TG (p < 0.001) and VLDL1 TG iAUCs (p < 0.001 and p = 0.012, respectively). Postprandial chylomicron apolipoprotein B-48 iAUC showed a significant decrease after Alo treatment (p = 0.028), and a non-significant trend towards a decrease with Alo/Pio (p = 0.213). The incidence of adverse events was low and consistent with previous studies. CONCLUSIONS/INTERPRETATION: Treatment with Alo and Alo/Pio produced significant reductions in postprandial TG and TG-rich lipoproteins, contributing to an improved overall cardiometabolic risk profile in type 2 diabetes. The data support the concept that incretins not only modulate glucose metabolism but also influence chylomicron metabolism in intestinal cells. TRIAL REGISTRATION: ClinicalTrials.gov number NCT00655863. FUNDING: The study was funded by Takeda Global Research & Development.

- AIMS/HYPOTHESIS: The study aimed to assess the relative importance of the control of HbA(1c) and total cholesterol/HDL-cholesterol ratio (TC/HDL) on risk of cardiovascular disease (CVD). METHODS: In 22,135 participants with type 2 diabetes (age 30-75 years, 15% with previous CVD) followed for 5 years, baseline and annually updated mean HbA(1c) and TC/HDL were analysed and also categorised in combinations of quartiles. Outcomes were fatal/non-fatal CHD, stroke, CVD and total mortality. RESULTS: In all participants, HRs per 1 SD increase in updated mean HbA(1c) or TC/HDL using Cox regression analysis were 1.13 (95% CI 1.07, 1.19) and 1.31 (1.25, 1.37) for CHD, 1.15 (1.06, 1.24) and 1.25 (1.17, 1.34) for stroke, 1.13 (1.08, 1.18) and 1.29 (1.24, 1.34) for CVD (all p < 0.001), and 1.07 (1.02, 1-13; p = 0.01) and 1.18 (1.12, 1.24; p < 0.001) for total mortality, respectively, adjusted for clinical characteristics and traditional risk factors. The p value for the interaction between HbA(1c) and TC/HDL was 0.02 for CHD, 0.6 for stroke and 0.1 for CVD. Adjusted mean 5-year event rates in a Cox model, in combinations of quartiles of updated mean TC/HDL and HbA(1c) (lowest <3.1 mmol/l and 5.0-6.4% [31-46 mmol/mol]; <3.1 mmol/l and ≥7.8% [≥62 mmol/mol]; ≥4.6 mmol/l and 5.0-6.4% 31-46 mmol/mol; and highest ≥4.6 mmol/l and ≥7.8% [≥62 mmol/mol]), were 4.8%, 7.0%, 9.1% and 14.5% for CHD, and 7.1%, 9.9%, 12.8% and 19.4% for CVD, respectively. Adjusted HRs for highest vs lowest combinations were 2.24 (1.58-3.18) for CHD and 2.43 (1.79-3.29) for CVD (p < 0.001). CONCLUSIONS/INTERPRETATION: Hyperglycaemia and hyperlipidaemia were less than additive for CHD and additive for other endpoints, with the lowest risk at lowest combination levels and a considerable increase in absolute risk at high combination levels.
