    • OBJECTIVE - To estimate the prevalence of and the cardiovascular risk associated with the metabolic syndrome using the new definition proposed by the World Health Organisation (WHO). RESEARCH DESIGN AND METHODS - A total of 4,483 subjects aged 35-70 years participating in a large family study of type 2 diabetes in Finland and Sweden (the Botnia study) were included in the analysis of cardiovascular risk associated with the metabolic syndrome. in subjects who had type 2 diabetes in = 1,697) impaired fasting glucose (IFG)/impaired glucose tolerance (IGT) (n = 798), or insulin-resistance with normal glucose tolerance (NGT) (n = 1,988). the metabolic syndrome was de fined as presence of at least two of the following risk factors: obesity hypertension, dyslipidemia, or microalbuminuria. Cardiovascular mortality was assessed in 3,606 subjects with a median follow-up of 6.9 years. RESULTS - In women and men, respectively, the metabolic syndrome was seen in 10 and 15% of subjects with NGT. 42 and 64% of those with IFG/IGT, and 78 and 84% of those with type 2 diabetes. The risk for coronary heart disease and stroke was increased threefold in subjects with the syndrome (P < 0.001). Cardiovascular mortality was markedly increased in subjects with the metabolic syndrome (12.0 vs. 2.2%, P < 0.001) Of the individual components of the metabolic syndrome, microalbuminuria conferred the strongest risk of cardiovascular death (RR 2.80. P = 0.002). CONCLUSIONS - The WHO definition of the metabolic syndrome identifies subjects with increased cardiovascular morbidity and mortality and offers a tool for comparison of results from different studies.

  • The metabolic syndrome influences the risk of chronic complications in patients with type II diabetes
  • 2001
  • Ingår i: Diabetologia. - : Springer Science and Business Media LLC. - 1432-0428 .- 0012-186X. ; 44:9, s. 1148-1154

    • AIMS/HYPOTHESIS: We examined features of the metabolic syndrome to see if they modified the risk of chronic diabetic complications in patients with Type II (non-insulin-dependent) diabetes mellitus. METHODS: A total of 85 randomly selected patients with the metabolic syndrome (WHO definition) were compared with 85 Type II diabetic patients matched for age, sex, duration of diabetes, glycaemic control and without the syndrome to assess the microvascular and macrovascular complications. RESULTS: The patients with the metabolic syndrome had a higher prevalence of cardiovascular disease (52 vs 21%, p < 0.001), microalbuminuria or macroalbuminuria (23 vs 7%, p = 0.003) and distal neuropathy (16 vs 6%, p = 0.048) than patients without the syndrome. The patients with the metabolic syndrome had smaller LDL particle size (25.4+/-1.4 vs 26.4+/-1.1 nm; p < 0.001), which correlated with the ratio of serum triglycerides to HDL cholesterol (r = -0.64, p < 0.001). In a multiple logistic regression analysis the metabolic syndrome was associated with coronary heart disease (RR 3.84, p < 0.001) and microalbuminuria (RR 3.99, p = 0.01). Small LDL particle size was independently associated with neuropathy (RR 0.58; p = 0.04), whereas a high HbA1c was related to neuropathy (RR 1.69, p = 0.04), retinopathy (RR 1.53, p = 0.002) and microalbuminuria (RR 1.54, p = 0.01). CONCLUSION/INTERPRETATION: Although chronic hyperglycaemia is the main predictor of microvascular complications in patients with Type II diabetes, this risk is modified by some of the components of the metabolic syndrome.

  • Familiality of metabolic abnormalities is dependent upon age at onset and phenotype of the type 2 diabetic proband.
  • 2003
  • Ingår i: American Journal of Physiology: Endocrinology and Metabolism. - : American Physiological Society. - 1522-1555 .- 0193-1849. ; 285:6, s. 1297-1303

    • To determine the impact of a family history of the common form of type 2 diabetes and the phenotype of the proband on anthropometric and metabolic variables in normoglycemic first degree relatives, we studied 2100 first degree relatives of patients with the common form of type 2 diabetes (FH+) and 388 subjects without a family history of diabetes (FH-). All subjects participated in an oral glucose tolerance test to allow measurement of insulin secretion (30min incremental insulin /glucose, I/G 30), and insulin sensitivity (HOMA insulin resistance). A subset participated in a euglycemic clamp (n=75) and an intravenous glucose tolerance test (n=300). To study the effect of a particular phenotype of the proband, insulin secretion and sensitivity were also compared between first degree relatives of diabetic probands with high and low waist to hip ratio (WHR) and probands with early and late onset of diabetes. FH+ subjects were more insulin resistant as seen from higher HOMA-IR index (P=0.007) and lower rate of insulin-stimulated glucose uptake (P=0.001) and had more features of the metabolic syndrome (P=0.02, P=0.0002) compared with FH- subjects. Insulin secretion adjusted for insulin resistance (disposition index, DI) was also lower in the FH+ vs FH- subjects (P=0.04). Relatives of diabetic probands with a high WHR had reduced insulin mediated glucose uptake compared with relatives of probands with a low WHR (P = 0.04). Relatives of diabetic patients with age at onset < 44 years had higher HOMA IR (P < 0.005) and lower DI (P < 0.005) than relatives of patients with age at onset >65 yrs (highest quartile). We conclude that early age at onset of type 2 diabetes and abdominal obesity have a significant influence on the metabolic phenotype in the non-diabetic firstdegree relative
