How is Down Syndrome Associated Arthritis diagnosed?

If there are any concerns about a child's joints, the GP and General/Community Paediatrician should be informed. If arthritis is suspected, children should be referred on to a specialist known as a 'Paediatric Rheumatologist'.

For most children, diagnosis can be made by a thorough musculoskeletal examination. Most children will also require additional blood tests to look for signs of inflammation in the blood, although these tests are not diagnostic.

While x-rays are nearly always requested, in some patients where the diagnosis is suspected or the clinical findings are very subtle, confirmation may be required with imaging tests such as contrast MRI or ultrasound.

How is Down Syndrome Associated Arthritis Treated and Managed?

DA is medically treated by a combination of non-steroidal anti-inflammatory medications, local joint injections and systemic treatment with biologic therapies. In addition to the medical treatments, there will likely be a referral to a physiotherapist and an occupational therapist.

Children with DA and their families receive additional support from the Clinical Nurse Specialist, and members of the specialist multidisciplinary team as part of the rheumatology team.

A referral to local ophthalmology (eye) services should also take place to screen for inflammation (uveitis) in the eye. as this is a potential complication that occurs with arthritis.

Psoriatic arthritis

Psoriatic arthritis (PsA) is an autoimmune disease - a form of inflammatory arthritis that can cause pain, swelling and sometimes damage to any joint in the body.
Sjogren's syndrome

Sjogren's syndrome is an auto-immune condition, where the body's natural self-defence system, gets confused and attacks the body's healthy tissues. White blood cells attack the body's tear and saliva glands, reducing the amount of saliva and tears produced, and causing a dry mouth and dry eyes, along with other related symptoms.
Juvenile idiopathic arthritis

Juvenile idiopathic arthritis (JIA) is the name given to several forms of arthritis in children and teenagers under 16. It is an auto-immune condition, and while it principally affects the joints, it may also affect other organs including the eyes.

Lupus

Systemic lupus erythematosus (SLE or lupus) is systemic disease, that can affect many different parts of your body. Cells and antibodies, which are in the blood to defend the body against infection, begin to attack it instead and cause inflammation.
Polymyalgia rheumatica

Polymyalgia rheumatica (PMR) is an inflammatory condition affecting the muscles in and around the shoulder and upper arm areas, buttocks and thighs.
Scleroderma

Scleroderma is a rare disorder of the body's connective tissues. It damages the cells that line the walls of the smaller arteries, such as those in the fingers and toes. Systemic scleroderma can damage the organs, while local scleroderma tends to affect the hands and face.
