Experiences of First Insulin-Treated Patients (1922-1923).

Abstract

Historical description of first insulin trials just after its discovery. The review includes first initiatives of insulin treatment. The probability of other trials, not reported to the Insulin Committee of the University of Toronto and conducted in the years 1922 and 1923, is quite low.

This historical review shows the quick progress from impure pancreatic extract to the selective isoelectric precipitation of the hormone, which made possible the introduction of insulin in the clinic. The coordination between the Departments of Physiology (Connaught Laboratories) and Medicine (Toronto General Hospital) was essential for the discovery and implementation of insulin therapy. The Insulin Committee was decisive for the negotiation with the pharmaceutical industry, the purification, grand-scale production, patents' achievement, and provision of licenses to expert clinicians and prestigious health centers. At the end of the year 1923, insulin treatment was already extended to Europe (mainly Scandinavia, Great Britain, and Spain). Insulin discovery and treatment changed the clinical spectrum of diabetes.
