title: [Lipoatrophic diabetes with acanthosis nigricans. Prolonged blood glucose normalization by continuous infusion of insulin].
abstract: Insulin resistance is a permanent feature of lipoatrophic diabetes, the resistance being almost regularly stubborn. We report the case of a 23-year old unmarried woman with generalized lipoatrophy and Acanthosis nigricans. Seven years after a diabetes resistant to all treatments was diagnosed, blood glucose levels were permanently around 25 mmol/l. Multiple and severe micro- and macroangiopathies were present. Partial resistance to insulin was demonstrated. This resistance could not be explained by abnormalities in anti-insulin hormones nor by a decrease in the number or affinity of insulin receptors, which suggested an intracellular abnormality below membrane receptors. Sustained control of glycaemia at a normal level was achieved by continuous infusion of insulin in high doses. It would appear that optimum insulin therapy using an insulin pump would offer hopes of therapeutic success in this particular form of insulin resistance.
