Growth hormone secretion in insulin-independent pregnant diabetics.
A study was initiated to determine whether hypersecretion of growth hormone (HGH) was involved in the inhibition of normal glucose metabolism in pregnant insulin-independent diabetic (IID). A total of 25 patients was studied, of whom 13 had normal glucose tolerance and 12 were recently diagnosed IIDs. Hgh secretion was stimulated by insulin-induced hypoglycemia. The mean basal HGH levels and the plasma HGH pattern following the insulin stimulus were similar in the study group and the normal controls. Although it is unlikely that HGH participates to any significant degree in the diabetogenicity of normal and diabetic pregnancy, final proof depends on the assessment of the biologically active inhibitory polypeptide fraction of HGH and the growth-promoting protein, somatomedin.
