General Description
Islet Cell Autoantibody (ICA) is a type of autoantibody that targets antigens within the pancreatic islets, particularly the beta cells that produce insulin. These antibodies are markers of autoimmune-mediated beta-cell damage and are crucial in the diagnosis and understanding of Type 1 diabetes (T1D).
ICA antibodies are present in the majority of patients with T1D, especially around the time of diagnosis. They are detected in up to 90% of patients with newly diagnosed T1D.
The presence of multiple autoantibodies (e.g., ICA, GAD65, IA-2A) in individuals at risk for T1D can help in stratifying the risk of disease progression. Those with multiple autoantibodies have a higher risk of developing T1D within 5 years
ICA antibodies, along with GAD65 and IA-2A, can also be used to diagnose LADA, a form of diabetes that requires insulin therapy and is often misdiagnosed as Type 2 diabetes.
