Still’s Disease: A Rare Inflammatory Disorder Marked by Elevated Ferritin
Still’s disease is a rare, systemic autoinflammatory condition that causes recurrent fevers , joint inflammation , and a distinctive salmon-colored rash . Though its exact cause is unknown, Still’s disease involves excessive activation of the immune system, leading to widespread inflammation. One of the key laboratory hallmarks of this disease is elevated ferritin levels , often far above the normal range. This article explores the symptoms, diagnosis, and treatment of Still’s disease—with a focus on the role of ferritin as both a diagnostic marker and an indicator of disease severity. What Is Still’s Disease? Still’s disease exists in two main forms: Systemic juvenile idiopathic arthritis (sJIA): Occurs in children and adolescents Adult-onset Still’s disease (AOSD): Develops in adults, typically between the ages of 16 and 35 Both forms share similar clinical features and are classified as autoinflammatory disorders, driven by innate immune system dysregulation rather t...
