Effect of hyperglycemia on the growth hormone response to L-dopa in diabetic subjects
- 4 Downloads
Plasma growth hormone (GH) levels were measured before and after oral administration of L-dopa in 8 insulin-dependent juvenile diabetic patients, and in 6 non insulin-dependent maturity-onset diabetics, while they were hyperglycemic, and values were compared with those of normal children and adult subjects. Maturity-onset diabetics failed to show an increase in serum GH levels after L-dopa administration, while serum peak GH values of juvenile diabetic patients were not significantly different from those of normal adults and children. Hyperglycemia thus failed to prevent L-dopa induced growth hormone response in insulin-dependent juvenile diabetic patients.
