[Improved glucose control and weight loss with exenatide in patients with type 2 diabetes: results of a retrospective observational multicentre Belgian study].

Abstract This is a retrospective analysis of medical records in 4 Belgian diabetes centres of 3 cohorts of patients with type 2 diabetes, with data available, respectively, after 3 months 10%, respectively. At 6 months, the composite criterion of a reduction of HbA(1c) by >1% or a final level <7% was reached by 69% of the cohort. Body weight decreased continuously over time, with a mean reduction of -2.1 kg at 3 months and -3.0 kg at 6 months (-4.9 kg at 9 months). The greater the baseline body weight, the greater the weight loss at final evaluation. Minor nausea and more rarely vomiting were observed, essentially during the first months of exenatide treatment. According to this observational study in routine practice, exenatide may be a valuable alternative to insulin for intensification of treatment of patients with type 2 diabetes after failure of oral drug combination, independently of baseline HbA(1c), body weight and duration of diabetes.
