A non-selected referred group (52) of country living, type 2 diabetics were commenced on exenatide. The 2 year response in 20 ,(M13.F,7.) were audited.
Mean age 60.5 years, weight 125kg (R102-152), HbA1c 9.3%, duration of diabetes 13.8yrs. Insulin users 16.
Severe co-morbidities were frequent. Obesity 100%, (BMI >35) Vascular disease 90%, Hypertension 45%, Sleep apnoea,55%, Hypercholesterolemia 60%,, Psychological 25%.
Methods. Assessment and biochemistry at all visits, reviewed at 3 months, then 6 month intervals for 2 years.
Treatment. Exenatide commenced 10ug dose for 2 weeks and then 10ug twice daily. Metformin continued (16). Sulfonylureas ceased (6)
Pre exenatide insulin mean daily dose (114 units) reduced stepwise over 4 weeks and ceased. If blood glucose values increased insulin was restarted at quarter original dose.
Results. (Mean ± SD.) Weight, initial 125 ± 19.4kg, 3 months 117 ± 21.1kg, 12 months 114.7 ± 19.3, 24 months 112 ± 22.3. 18 lost weight except 2 who increased by 15kgs.
The HbA1c initial 9.3% ± 1.2 (R 7.9-12), 3months 8.3% ± 1.3, 12 months 8.2% ± 1.4, 24 months 8.0 ± 1.5. At commencement no one had an HbA1c < 7%. After 2 years 7 were 7% or less.
Insulin was restarted in 6. Oral hypoglycaemics were added in 6.
There was no significant change in creatinine, lipids liver function, or blood pressure.
Side effects. Exenatide caused nausea in 7 but not discontinued.
Conclusions. The use of exenatide resulted in a significant weight loss of 13kg, HbA1c decreased by 1.3%, insulin ceased in 10, reduced daily insulin dose to 30 units, and an overall sense of satisfaction at the weight loss and improved diabetic control which had not previously occurred.
