Studies on patients with long-term diabetes survival without severe complications can give information about protective factors. Therefore, the present study aims to describe the long-term survival of patients with diabetes during successive periods following the introduction of insulin therapy in 1923. After registration in 1973 of the first local diabetic patient in Jonkoping with a fifty-year survival, this group has successively increased. Of those who were diagnosed during the period 1940 through 1949 there was a fifty-year survival in about one third. The successively better survival emphasises the importance of therapeutic progress. The study found no difference in diabetes control between those surviving 50 years and those with an age-matched group with a survival of 15 years. The insulin dose tended to decrease after 30 years duration. Peripheral vibration sensibility as well as renal function deteriorated by longer duration. The serum ratio of HDL-cholesterol to triglycerides increased. The frequency of glaucoma, cataract, and a history of myocardial infarction increased. In spite of long duration, one third of the sample had escaped serious retinopathy.
