OBJECTIVE: To determine (1) whether long-term treatment with exenatide is associated with reductions in C-reactive protein (CRP), systolic blood pressure (BP), and triglyceride concentrations in addition to reductions in body weight and hemoglobin A(₁c) (A1C) levels and (2) whether these beneficial results persist without any loss of effect while exenatide is being used, and whether they reverse after its cessation. METHODS: We conducted a retrospective review of 141 patients with type 2 diabetes mellitus treated with exenatide at a tertiary clinic. RESULTS: Exenatide (mean duration of treatment, 1.4 years) decreased A1C (0.7%), weight (5 kg), systolic BP (8 mm Hg), and triglyceride concentrations (46 mg/dL) (P<.05 for all). Sixty-one patients continued exenatide therapy throughout the study (mean duration of use, 2.4 years). Exenatide treatment reduced their mean weight by 7 kg, systolic BP by 8 mm Hg, triglycerides by 52 mg/dL, A1C by 1.3%, and CRP by 2.4 mg/L (P<.05 for all). Reductions in systolic BP and CRP were not related to weight loss. The reduction in CRP concentration was significantly related to the baseline CRP concentration (r = 0.78; P<.001) and to change in A1C (r = 0.68; P = .02). Patients who stopped taking exenatide had a reversal of the benefits within 6 months after cessation of treatment. CONCLUSION: Exenatide treatment in patients with type 2 diabetes has durable and persistent beneficial effects on A1C, weight, CRP, systolic BP, and triglyceride concentrations. Cessation of treatment reverses all these beneficial effects within 6 months. There was no evidence of loss of its effects while exenatide treatment was continued.
