An international panel has issued detailed guidance on screening children for early signs of type 1 diabetes, promoting earlier detection to prevent severe complications and enable timely intervention.
An international panel of specialists has set out the first detailed guidance for screening children across the general population for early signs of type 1 diabetes, in an effort to catch the disease before symptoms emerge. The consensus, published in Diabetologia, recommends a staged testing approach that can identify children with islet autoantibodies, the blood markers that show the autoimmune process has already begun. According to the Centres for Disease Control and Prevention, type 1 diabetes often develops silently for some time, which is why earlier detection can matter so much.
The guidance recommends a first screening between the ages of two and four, then repeat testing if no autoantibodies are found at ages six to eight and again between 10 and 15. Researchers involved in previous cohort studies, including work published in The Lancet Diabetes & Endocrinology, have found that these are periods when autoantibodies commonly first appear. The new advice also allows countries to phase in screening gradually, beginning with higher-risk children before extending programmes more widely.
Experts say the main value of screening is that it can lower the chance of diabetic ketoacidosis, a dangerous complication that may occur when diabetes is first diagnosed. The CDC says early detection can reduce that risk, and a study in JAMA found that screening children can identify those at risk before symptoms start. Mayo Clinic specialists have also noted that finding children in the early stages of the disease creates a chance to monitor them more closely and, in some cases, consider therapies that may delay progression.
The consensus stresses that screening should not be limited to families already known to have type 1 diabetes. More than 85% of people newly diagnosed do not have a family history, according to the paper. It also says that once autoantibodies are confirmed, progression tends to follow a similar course regardless of family history. The authors, led by Anette-Gabriele Ziegler of Helmholtz Munich, said diagnosis should be confirmed through a step-by-step process and explained to families in person with access to psychosocial support. The recommendations have been backed by 20 professional and patient organisations, including the European Association for the Study of Diabetes, the International Society for Pediatric and Adolescent Diabetes and IDF Europe.
