Most people think that arthritis only affects older people. The truth is one in 800 Australian children has a form of juvenile idiopathic arthritis 1.
It’s one of the most common chronic conditions to affect children.
If we break the words up, it provides some clues about juvenile idiopathic arthritis:
So JIA is a group of conditions that causes joint pain and swelling in children and teens under the age of 16, for some unknown reason.
Other names that it may be called include: juvenile rheumatoid arthritis, juvenile arthritis, juvenile chronic arthritis and Still’s disease.
We don’t really know what causes JIA. But we do know that it occurs as a result of a malfunctioning immune system.
Your immune system is designed to identify foreign bodies (e.g. bacteria, viruses) and attack them to keep you healthy. However in the case of JIA, the immune system mistakenly attacks healthy tissue in and around the joints, causing ongoing inflammation and pain.
There are different types of JIA including:
This is the most common form of JIA. It’s also sometimes called pauciarticular JIA. ‘Oligo’ and ‘pauci’ means not many or few – so few joints are affected.
Polyarticular JIA affects five or more joints. ‘Poly’ means many. There are two types of polyarticular JIA:
Systemic JIA can affect many areas of the body, not just the joints. It’s the least common type of JIA.
Entheses are the tissues that attach tendons and ligaments to the bone. This type of JIA affects the entheses as well as the joints.
Children with psoriatic JIA have inflammatory arthritis of the joints and the skin condition psoriasis.
This is where the condition doesn’t fit any of the above types of JIA.
There are other musculoskeletal conditions that can also affect children, for example Perthes’ disease, fibromyalgia, scleroderma and lupus. For information on these conditions, please contact our MSK Help Line.
The symptoms your child experiences will depend on the type of arthritis they have. Common symptoms include:
Less common symptoms include:
JIA is diagnosed using a number of tests including:
While there’s currently no cure for JIA, treatment can help manage the symptoms. Working closely with your healthcare team will lead to the best outcomes for your child.
Doctors, nurses, physiotherapists, occupational therapists, dietitians, podiatrists, psychologists and social workers may all be a part of the team that treats your child.
Most children with JIA – regardless of the type – will have to take some form of medication at some time. It depends on the symptoms they’re experiencing. There are many different types of medications that work in different ways.
Your doctor will always start with the simplest medications at the smallest doses and work their way up to more complex medications and larger doses depending on how your child’s condition responds to the treatments.
The most common types of medications used are:
There are many things you and your child can do to manage their condition such as:
Follow the plan that your health professionals have developed. That means taking medications as they’ve been prescribed, doing the exercises the physiotherapist and/or occupational therapist have provided, and letting your doctor know of any changes to your child’s symptoms and how they’re feeling. All of these things give your child a better chance of managing their JIA well and reducing the risk of long-term problems.
Stay active – physical activity is the key to maintaining muscle strength, joint flexibility and managing pain. A physiotherapist or exercise physiologist can help design an individual program for your child.
Learn ways to manage pain – from heat and cold treatments, distraction, massage and medication, there are many ways your child can manage pain. Try different techniques until you find the things that work best for your child.
Eat well – while there’s no diet that can cure JIA, a healthy and well-balanced diet is the best for good health. Keeping to a healthy weight is also important as extra weight puts added strain on your child’s joints, especially load bearing joints such as hips, knee and ankles.
Protect joints – find out about aids, equipment and gadgets that can make tasks easier. An occupational therapist can give you advice.
Stay at school – it’s good for your child’s health and wellbeing. Talk to your doctor, allied health professionals and teachers about ways to help your child stay at school, and keep up with school.
