title: [Variation in serum nonesterified fatty acids during glucose tolerance test in undernourished patients with anorexia nervosa and in obese patients].
abstract: Intravenous glucose tolerance tests (0,33 g glucose per kg body weight) are performed in 11 self starved women suffering from anorexia nervosa, 10 obese and 8 normal women. They have no genetic or chemical diabetes and belong to the same age group. Plasma concentrations of immuno-reactive insuline (IRI) and non esterified fatty acids (NEFA) are determined during these tests. The basal concentrations of NEFA are very high in the obese patients. In the starved women the elevation of the basal plasma NEFA concentration is less striking and statistically not significant. The plasma level of NEFA is reduced in all subjects by hyperinsulinism secondary to hyperglycemia. This drop in NEFA concentration is significantly reduced in the obese patients and markedly inhibited in the starved women. This observation points toward an increased resistance to the antilipolytic action of insulin in anorexia nervosa because, in these patients, the glucose load determines a normal increase in plasma IRI but the fall in plasma NEFA concentration is severely impaired.
