Vasculitis is a group of autoimmune diseases that cause inflammation of blood vessels, potentially leading to complications such as organ damage, restricted blood flow, and tissue destruction. While vasculitis in adults is more commonly associated with underlying conditions like diabetes or hypertension, in children, it often stems from autoimmune or infectious triggers. The symptoms in Types of Vasculitis in Children Common forms of vasculitis seen in children include: Henoch-Schönlein Purpura (HSP): The most frequent type in children, causing rash, joint pain, abdominal pain, and kidney involvement. Kawasaki Disease: Affects young children, leading to fever, rash, and potential heart complications. Polyarteritis Nodosa (PAN): A rare but severe form involving medium-sized arteries, often leading to organ damage. Takayasu Arteritis: A rare condition that affects large blood vessels, particularly the aorta and its branches. How Pediatric Vasculitis Differs from Adults Causes: Pediatric vasculitis often stems from infections or an abnormal immune response, while adult cases may involve chronic conditions like rheumatoid arthritis or lupus. Symptoms: Children often present with non-specific symptoms such as fatigue, fever, or irritability, making early diagnosis challenging. Complications: Growth delay and developmental issues are unique concerns in children with chronic vasculitis. Prognosis: With early intervention, children generally have better outcomes compared to adults.
