Pathophysiology of Latent Autoimmune Diabetes

Latent Autoimmune Diabetes in Adults (LADA) is a type of diabetes that exhibits features of both Type 1 and Type 2 diabetes. It typically manifests in adults over the age of 30 and is characterized by a gradual onset of insulin deficiency due to autoimmune destruction of pancreatic beta cells. Unlike classic Type 1 diabetes, LADA progresses more slowly, often initially being misdiagnosed as Type 2 diabetes due to the presence of insulin resistance. The pathophysiology involves the activation of autoantibodies against pancreatic islet cells, leading to an inflammatory response and subsequent beta-cell dysfunction. This autoimmune attack results in a gradual decline in insulin production, ultimately necessitating insulin therapy. Understanding LADA is crucial for appropriate management, as early intervention can help delay complications associated with diabetes.
