Abstract

To evaluate the clinical utility of pioglitazone therapy in patients who previously received troglitazone. We undertook an observational study involving patients with type 2 diabetes, who were originally treated with troglitazone and subsequently converted to pioglitazone therapy. Drug efficacy was evaluated by comparing baseline hemoglobin A1c (HbA1c) levels, weight, blood pressure, and lipid profiles (during troglitazone treatment) with corresponding values 6 months after final pioglitazone dose titration. Drug safety was evaluated by review of hepatic enzyme levels and documented reports of side effects. The study cohort consisted of 316 patients in whom pioglitazone therapy was initiated after they had received troglitazone for at least 1 year. Discontinuation of pioglitazone treatment subsequently occurred in 43 patients; in 7 additional patients, no follow-up occurred. We found no significant difference between baseline and follow-up mean HbA1c values. Aspartate aminotransferase levels did not significantly change after 6 months of pioglitazone therapy; however, alanine aminotransferase levels increased by a statistically significant 3.8 U/L (95% confidence interval, 2.6 to 4.9). Pioglitazone treatment was discontinued be...Continue Reading

Biomarkers for Type 2 Diabetes

Biomarkers can help understand chronic diseases and assist in risk prediction for prevention and early detection of diseases. Here is the latest research on biomarkers in type 2 diabetes, a disease in which the body is unable to produce or properly use insulin.
