- OBJECTIVE - To evaluate whether treatment with insulin in recently diagnosed type 2 diabetes is advantageous compared with glibenclamide treatment. RESEARCH DESIGN AND METHODS - ▀-Cell function, glycemic control, and quality of life were monitored over 2 years in 39 patients with islet cell antibody-negative type 2 diabetes diagnosed 0-2 years before inclusion in a Swedish multicenter randomized clinical trial. Patients were randomized to either two daily injections of premixed 30% soluble and 70% NPH insulin or glibenclamide (3.5-10.5 mg daily). C-peptide-glucagon tests were performed yearly in duplicate after 2-3 days of temporary withdrawal of treatment. RESULTS - After 1 year the glucagon-stimulated C-peptide response was increased in the insulin-treated group by 0.14 ▒ 0.08 nmol/l, whereas it was decreased by 0.12 ▒ 0.08 nmol/l in the glibenclamide group, P < 0.02 for difference between groups. After 2 years, fasting insulin levels were higher after treatment withdrawal in the insulin-treated versus the glibenclamide-treated group (P = 0.02). HbA1c levels decreased significantly during the first year in both groups, however, at the end of the second year, HbA1c had deteriorated in the glibenclamide group (P < 0.01), but not in the insulin-treated group. The difference in evolution of HbA1c during the second year was significant between groups, P < 0.02 A questionnaire indicated no difference in well-being related to treatment. CONCLUSIONS - Early insulin versus glibenclamide treatment in type 2 diabetes temporarily prolongs endogenous insulin secretion and promotes better metabolic control.

- 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.
