Pediatric autoimmune diseases occur when a child's immune system mistakenly attacks its own healthy cells and tissues. This can lead to various health issues, including inflammation, pain, and organ damage. Common examples include juvenile idiopathic arthritis, type 1 diabetes, and lupus. These conditions can affect children of any age and may require long-term management. Treatment often involves medications to reduce inflammation and suppress the immune response. Early diagnosis and intervention are crucial to help manage symptoms and improve the quality of life for affected children.
