Abstract
  • Background. Free fatty acids (FFAs) are linked to impaired insulin action, but their role in mediating long-term insulin sensitization during diabetes treatment is unclear. Objectives. To examine the effect of pioglitazone addition to existing therapy on FFA dynamics and insulin action. Design. Two 2-year, randomized, parallel-group, double- blind, double-dummy, clinical trials. Setting. One hundred and seventy-one centres in Europe, Australia and Canada. Subjects. Male and female patients with Type 2 diabetes inadequately managed with metformin or sulfonylurea. Interventions. Patients were randomized to pioglitazone (15-45 mg day)1; n = 319) or metformin (850-2550 mg day)1; n = 320) as add-on therapy to gliclazide or pioglitazone (n = 317) versus gliclazide (80-320 mg day)1; n = 313) as add-on therapy to metformin. Outcome measure. Plasma FFA profiles during oral glucose tolerance tests in selected centres before and during treatment (n = 588). Results. At Week 104, pioglitazone treatment decreased fasting FFAs by 0.08 mmol L)1 when added to sulfonylurea and by 0.11 mmol L)1 when added to metformin versus the respective sulfonylurea + metformin groups (0.03 mmol L)1, P = 0.05 and 0.04 mmol L)1, P < 0.05), and this was accompanied by significant improvements in fasting adipose tissue insulin sensitivity. Changes in postchallenge FFAs were similar between groups and not related to changes in liver transaminases, insulin action and secretion. However, the sensitivity of FFA to insulin was affected by treatment (P < 0.001) and visit (P < 0.05). Insulin sensitivity of FFA rose when pioglitazone was added to sulfonylurea (P < 0.05), but decreased for gliclazide + metformin (P < 0.05). Conclusion. Long-term improvements in adipose tissue insulin sensitivity and reduction in fasting FFAs with pioglitazone may help to reduce lipotoxicity in Type 2 diabetes. (literal)
