[Info-congress.  Insulin therapy for preventing type 1 diabetes in high-risk relatives: negative results of the "Diabetes Prevention Trial-Type 1"]. 
The results of the American multicentre "Diabetes Prevention Trial-Type 1" were presented by J. Skyler during the last congress of the American Diabetes Association in Philadelphia on June 23, 2001.  The prophylactic subcutaneous administration of low-dose insulin was not able to prevent the development of type 1 diabetes nor to preserve residual insulin secretion in young relatives at very high-risk of diabetes (> 50% in the next 5 years), selected upon genetic, immunological and metabolic criteria.
