Abstract

In genetic prediabetic subjects (the glucose tolerant offspring of two diabetic parents or the identical twin of a known diabetic) serum insulin concentrations after glucose administration are subnormal. Maintenance of glucose tolerance in this setting is apparently paradoxical, suggesting increased tissue insulin sensitivity. Accordingly, forearm tissue insulin sensitivity in nine genetic prediabetic males was compared with that of seven males without familial diabetes. Diabetes was excluded in all subjects by preliminary oral glucose tolerance testing.
