For most people, the onset of type 1 diabetes seems to occur suddenly, often resulting in a trip to the emergency room with life-threatening complications such as diabetic ketoacidosis (DKA). The Naomi Berrie Diabetes Center is a member of TrialNet, a worldwide leader in type 1 diabetes prevention research and one of the prominent organizations working to change that scenario.
In the January 2016 issue of Diabetes Care, the JDRF, American Diabetes Association (ADA), and Endocrine Society recommended adoption of a new type 1 diabetes staging classification. This recommendation is largely based on two decades of TrialNet research involving more than 150,000 relatives of people with type 1 diabetes.
Type 1 diabetes can now be most accurately understood as a disease that progresses in three distinct stages.
Stage 1 is the start of type 1 diabetes. Individuals test positive for two or more diabetes-related autoantibodies. The immune system has already begun attacking the insulin-producing beta cells, although there are no symptoms and blood sugar remains normal.
Stage 2, like stage 1, includes individuals who have two or more diabetes-related autoantibodies, but now, blood sugar levels have become abnormal due to increasing loss of beta cells. There are still no symptoms.
For both stages 1 and 2, lifetime risk of developing type 1 diabetes approaches 100 percent.
Stage 3 is when clinical diagnosis has typically taken place. By this time, there is significant beta cell loss and individuals generally show common symptoms of type 1 diabetes, which include frequent urination, excessive thirst, weight loss, and fatigue.
The new staging classification is vital to understanding how type 1 progresses. Equally important is TrialNet’s ability to diagnose the disease in its earliest stages, allowing for prompt intervention.
According to TrialNet Chair Carla Greenbaum, MD, “Identification of the pre-symptom stages of type 1 diabetes can be compared to identification of high blood pressure as a predictor of heart attack and stroke. Before treatment for high blood pressure became commonplace, we were missing a key tool to prevent heart disease. Today, people can receive intervention long before they experience symptoms or significant complications. The same is now true for type 1 diabetes.”
Clinical research supports the usefulness of diagnosing type 1 diabetes early—before beta cell loss advances to stage 3. The earlier diagnosis is made in the disease process, the sooner intervention can take place, and the more beta cells are likely to remain. More beta cells may lead to better outcomes regarding blood sugar control and reduction of long-term complications.
Dr. Robin Goland, TrialNet Principal Investigator at The Naomi Berrie Diabetes Center, explains, “TrialNet’s goal is to identify the disease at its earliest stage, delay progression, and ultimately prevent it. We offer screening and clinical trials for every stage of type 1 diabetes and close monitoring for disease progression.”
For people who participate in type 1 diabetes prevention research like TrialNet, the risk of DKA at diagnosis decreases from 30 percent to less than 4 percent.
Both the ADA and JDRF recommend TrialNet screening for people who have relatives with type 1 diabetes. Family members have a 15 times greater risk of being diagnosed than a person with no family history. Screening is available at no charge to:
- anyone between the ages of 1 and 45 with a sibling, child or parent with type 1 diabetes.
- anyone between the ages of 1 and 20 with a sibling, child, parent, cousin, uncle, aunt, niece, nephew, grandparent, or half-sibling with type 1 diabetes.
It is recommended that children who do not test positive for diabetes-related autoantibodies continue to get rescreened every year until age 18.
The Naomi Berrie Diabetes Center offers TrialNet screening and intervention studies. For further information, contact Ellen Greenberg, Lead Coordinator at 212-851-5425 or firstname.lastname@example.org.
About The Naomi Berrie Diabetes Center
The Naomi Berrie Diabetes Center at Columbia University Medical Center is recognized nationally and internationally for excellence and innovation in patient care and research in diabetes. The Berrie Center combines a large multi-disciplinary clinical care program for children and adults with diabetes with a cutting-edge basic and translational diabetes research program. More than 50 faculty at Columbia are involved in diabetes research at the Berrie Center; 143 graduate and postdoctoral students have or are being trained in the Berrie Center.
More than 10,000 patients are cared for at the Berrie Center. Our pediatric diabetes program has rapidly become among the nation’s largest. The caliber of care these patients receive is superb. Diabetes education is central to the Berrie Center program. We have the faculty and resources to work with patients as individuals, to engage their families and loved ones, and to help them with the challenging self-care practices that are necessary to achieve optimal care of diabetes. Our goal is wellness, maintenance of good health, and prevention of complications.
Our extensive clinical trials program affords patients access to cutting-edge research in type 1 and type 2 diabetes. The close proximity of our clinical and basic science faculty and programs greatly facilitates translational research in diabetes.

TrialNet is an international network of leading academic institutions, physicians, scientists, and healthcare teams at the forefront of type 1 diabetes research. Funded by the National Institutes of Health, TrialNet offers risk screening for relatives of people with type 1 diabetes and innovative clinical studies to preserve insulin production before and after diagnosis. There are more than 200 TrialNet screening sites worldwide. Screening test kits are also available by mail.
TrialNet is funded by the National Institute of Diabetes and Digestive and Kidney Diseases, part of the National Institutes of Health (NIH) and other NIH components, including the National Institute of Allergy and Infectious Diseases and the Eunice Kennedy Shriver National Institute of Child Health and Human Development. It is also supported by JDRF and American Diabetes Association. Learn more at DiabetesTrialNet.org.
