Type 1 diabetes incidence has been increasing every year, especially in infants; the disease is often diagnosed at an advanced stage with diabetic ketoacidosis already present. Diagnosis at an early stage can prevent complications, and is one of the objectives in the Fr1da study, the first project of its kind worldwide that has screened more than 33000 infants aged two to five years for islet antibodies since January 2015. The first three cases that were diagnosed with an early stage of type 1 diabetes (positive for two or more islet autoantibodies) have already been included in a structured follow-up programme. The present contribution will cover these cases as examples for the process from positive screening result to individual prediabetes training.
