Still's disease

What is Still's disease?

Still's disease is also known as systemic-onset juvenile rheumatoid arthritis. This is just one of the many ways juvenile rheumatoid arthritis can present itself. It is characterised by high spiking fevers and a salmon-coloured skin rash. These symptoms often occur with other systemic symptoms, including swelling of the lymph glands, enlargement of the spleen and liver, sore throat, and inflammation of lungs and heart. Eventually all patients with Still's disease develop joint pain and swelling, the typical signs and symptoms of rheumatoid arthritis.

Who gets Still's disease?

Still's disease accounts for about 10-20% of the total cases of juvenile rheumatoid arthritis. It usually begins in early childhood between 1-4 years. Although rare, Still's disease can develop in adults (adult-onset Still's disease). In 75% of cases this occurs between 16-35 years of age.

What is the cause of Still's disease?

The exact cause of Still's disease is not known. One theory is that the disease is caused by infection with a microbe. Another theory is that Still's disease is a hypersensitive or autoimmune disorder (this is where the body's immune system which normally fights off infections or illness suddenly starts to attack the body's cells and tissues it is suppose to protect).

What are the signs and symptoms of Still's disease?

The main signs and symptoms of Still's disease include:

In many cases, skin rash and fever may occur intermittently for months or even years before joint pain and swelling develop. All patients with Still's disease eventually develop persistent chronic arthritis even if fever and systemic symptoms have stopped. Arthritis usually affects many joints but in particular the wrists may become severely deformed.

What is the treatment of Still's disease?

There is no cure for Still's disease. The main goals of treatment are to reduce joint inflammation and avoid deformity. Therapy may include both medical and surgical interventions. In addition, the patient and their families need to fully understand the nature of the disease and how to live with it for the rest of their lives.

Drug therapy to control many of the symptoms of Still's disease includes:

Non-drug therapy includes physiotherapy, hydrotherapy and simply rest. Patients with Still's disease will experience “good” and “bad” days. The number of “bad” days, that is flare-ups or exacerbations of the disease, can be controlled or reduced by careful planning of activities and rest periods. It has been shown that physical and emotional stress can exacerbate symptoms of Still's disease.

Anakinra

There are several anecdotal reports in the literature of successful treatment of adult onset Still's disease with anakinra. Results of the first open 24 week, comparative, multicenter study in 22 patients randomised to receive anakinra (n=12) or disease modifying antirheumatic drugs (n=10) have shown that anakinra produced significantly more rapid and sustained responses.
