Autoinflammatory diseases are a group of disorders characterized by seemingly unprovoked inflammation. These conditions can present with recurring fevers and often happen with other symptoms like headaches, joint pains, abdominal pain and rashes. Some autoinflammatory diseases include:
Children with juvenile idiopathic arthritis (JIA) have joint inflammation called arthritis. When a joint has arthritis, it may feel warm, swollen, stiff, painful and tender when touched. These symptoms happen because of inflammation in the joint. Some children may only have mild symptoms in a few joints while others may have more serious symptoms like high fever, skin rash and swollen lymph nodes.
The main types of JIA are:
Treatments are focused on decreasing pain, improving/maintaining function and movement, and preventing damage. Treatment often includes medicines that calm the immune system, such as steroids and disease modifying anti-rheumatic drugs (DMARDs), along with physical and occupational therapy to help improve strength and movement.
Inflammatory myositis, also called inflammatory myopathy, is a group of rare autoimmune diseases where the immune system attacks the muscles. This causes muscle inflammation, weakness, and pain. Other symptoms may include fatigue and rarely difficulty swallowing or breathing. Some patients with a condition known as juvenile dermatomyositis (JDM) also experience skin rashes along with muscle weakness. Treatments are focused on decreasing pain, improving/maintaining function and movement, and preventing damage. Treatment often includes medicines that calm the immune system, such as steroids and disease modifying anti-rheumatic drugs (DMARDs), along with physical and occupational therapy to help improve strength and movement.
Sometimes muscle and joint pains are caused by reasons not explained by an autoimmune or rheumatologic condition (meaning it is not caused by the immune system attacking the muscles or joints). A rheumatologist can help rule out these other causes of pain, if needed. These primary pain conditions in which the nerves on the tissue send amplified pain signals to the brain include chronic widespread pains related to fibromyalgia or localized pain due to complex regional pain syndrome. Joint hypermobility, a condition in which tissues around the joints are very flexible, can sometimes be a cause of localized or more widespread pains. Examples include:
Scleroderma is a rare, long-term autoimmune disease. There are two main forms of scleroderma: localized (morphea) or diffuse (systemic). In general, scleroderma causes the skin and connective tissues in the body to become hard and tight because the body makes too much collagen. Scleroderma can affect only small areas of skin (localized), or it can affect the whole body (systemic). In severe cases, it can also damage internal organs like the heart, lungs and kidneys. There is no cure for scleroderma, but treatments can help manage symptoms and prevent damage. These may include medicines to lower immune system activity, improve blood flow, and reduce scarring.
Uveitis is inflammation (swelling) of the eye's middle layer (uvea), often caused by autoimmune disorders, infections or injury, and can cause permanent vision loss if untreated. Some children may not experience any symptoms while others may have red, painful eyes, light sensitivity and blurry vision. Treatment is focused on reducing inflammation and preventing damage. Treatment usually involves steroids (eye drops, pills or injections) along with other disease modifying anti-rheumatic drugs (DMARDs). Prognosis is good especially if caught early.
