RESUMO

BACKGROUND: Although diabetes is associated with a high cardiovascular risk, very little information is available about diabetic patients enrolled in cardiac rehabilitation (CR). AIMS: To analyse the characteristics of diabetic patients and diabetes care in CR. METHODS: From the database of 700 patients enrolled in CR during a 29-month period, we analysed data from all patients with glucose metabolism disorders (n=105) and 210 matched normoglycaemic patients. RESULTS: A total of 105 patients with glucose metabolism disorders (type 1 diabetes, n=5; type 2 diabetes, n=84; impaired fasting glucose, n=16) were enrolled in a CR programme (15% of whole population). Fifteen per cent of patients with type 2 diabetes and all patients with impaired fasting glucose were diagnosed during CR. These 105 patients were older and had a higher body mass index, a larger waist circumference, higher fasting blood glucose and triglyceride concentrations and lower low-density lipoprotein cholesterol concentrations than non-diabetic patients; they also had higher rates of hypertension (P=0.001) and dyslipidaemia (P=0.02). They were more frequently referred to CR for peripheral artery disease (P=0.001), coronary heart disease+peripheral artery disease (P=0.007) and primary prevention (P=0.009). The intervention of a diabetologist was needed for 42.6% of patients because of uncontrolled or newly diagnosed diabetes. CONCLUSION: In the present study, we showed that (1) the proportion of patients with diabetes in CR is lower than expected, (2) many glucose metabolism disorders are diagnosed during CR, (3) patients with glucose metabolism disorders show a more severe cardiovascular risk profile than normoglycemic patients, and (4) the intervention of a diabetologist is needed during CR for many patients with diabetes.

RESUMO

CONTEXT: Apelin is an adipokine expressed in several tissues and it appears to be involved in energy metabolism. OBJECTIVE: The aim of this study was to determine serum apelin levels in a large cohort of patients with type 1 and type 2 diabetes and control subjects and to correlate the results with glycaemic control. DESIGN AND PARTICIPANTS: One hundred and thirty patients with type 1 diabetes, 98 patients with type 2 diabetes and 162 controls were enrolled in the study. Apelin levels were measured by enzyme-linked immunosorbent assay. RESULTS: Serum apelin levels were significantly higher in type 1 and type 2 diabetic patients than in controls (P < 0·0001). Serum apelin levels were higher in type 1 than in type 2 diabetic patients (P = 0·02). In multivariate analysis, serum apelin levels were higher in patients with type 1 diabetes and in patients with type 2 diabetes versus controls. We found a negative correlation between glycosylated haemoglobin and serum apelin levels in all diabetic patients (r = -0·17, P = 0·008) and in patients with type 2 diabetes (r = -0·24 P = 0·01). No correlation was found in type 1 diabetic patients. CONCLUSION: Our study showed that apelin concentrations were increased in diabetic patients. This rise, which was greater in type 1 than in type 2 diabetic patients, suggests that obesity is not the main determinant of plasma apelin levels. The negative correlation with glycosylated haemoglobin in patients with type 2 diabetes could indicate that apelin plays a role in glycaemic balance and even insulin sensitivity.

RESUMO

UNLABELLED: We investigated how liver fat content (LFC) influences cholesterol metabolism by quantifying liver fat using proton magnetic resonance spectroscopy and by measuring the serum concentrations of lathosterol, a marker of cholesterol synthesis, and sitosterol and campesterol, two markers of cholesterol absorption. We also evaluated whether this relationship could be modified by statin therapy. The study was conducted in 263 patients with type 2 diabetes, 137 of whom (52.0%) received statin therapy. RESULTS: One hundred and sixty-five patients (62.7%) had steatosis (LFC>5.5%). We performed specific analyses in patients without statin therapy and in patients treated with statin therapy. In both groups, the lathosterol to cholesterol ratio correlated positively with LFC, and in multivariate analysis, the lathosterol to cholesterol ratio was associated with LFC independently of age, gender and BMI. Sitosterol and campesterol concentrations were not associated with LFC. CONCLUSIONS: Our study suggests that in patients with type 2 diabetes, LFC is associated with an increase in cholesterol synthesis that is independent of obesity or diabetes mellitus. Statin therapy does not modify this relationship.
