Does your child complain of joint pain? Does he sometimes have trouble walking in the morning? If so, this information will be very important to you. Today we are going to talk about a somewhat complicated, but manageable condition that affects young children. That is juvenile idiopathic arthritis, or as we doctors call it, `(Juvenile Idiopathic Arthritis)` or `(JIA)`.
What is juvenile rheumatoid arthritis (JIA)? Let's understand it simply!
Simply put, `(JIA)` is the most common type of arthritis in children. It is a chronic condition, meaning it can affect a child for a long time. It can affect any joint in a child's body.
Think about it, our body has an immune system. That's what protects us from diseases. But `(JIA)` is an `autoimmune disease` . That means, the child's own immune system mistakenly attacks parts of its own body, especially the `(synovium)` tissue and joint fluid inside the joints. It's like a thief breaking into your own house.
Because of this impact, the synovium produces more joint fluid. This is when the joints swell, become painful, and feel stiff.
This immune system response and the resulting inflammation can also affect surrounding tissues, eventually damaging cartilage and bone. This inflammation can also affect other parts of the child's body, especially the eyes. If left untreated, JIA can interfere with a child's normal growth and development. However, with good treatment, a child's quality of life can improve significantly.
JIA is the most common type of arthritis in children. It is estimated that about one in 1,000 children in the United States alone has the condition.
What are the main types of (JIA)?
There are several main types of JIA. These are classified based on symptoms and the number of joints affected. Let's take a look at what they are.
Oligoarticular JIA
This is also called `(Oligoarthritis)`. In this type , fewer than five joints are affected. Most often, joints such as the knees, ankles, and elbows are affected. It can also affect the eyes, which is called `(Uveitis)`. Sometimes it is difficult to detect it without an eye exam. About half of children with `(JIA)` belong to this type. It is more common in girls. Most children can get rid of this condition by the time they reach adulthood. However, in some children, it can spread to many more joints.
Polyarticular JIA
This is also called `(Polyarthritis).` In this type , five or more joints are affected. Often, the same joints are affected on both sides of the body. It can also affect the joints in the neck, jaw, and small joints in the hands and feet. It is also more common in girls. About 20% of `(JIA)` patients belong to this type.
Psoriatic JIA
This is also called `(Psoriatic Arthritis)`. This means that the child has arthritis along with the skin disease `(Psoriasis)` (a condition that causes red patches on the skin, such as silvery scales on the surface of the skin). However, if the child does not have `(Psoriasis)` but has other symptoms, for example, swelling of a finger or toe, certain changes in the nails, or if a first-degree relative in the family has `(Psoriasis), this condition can be diagnosed as `(Psoriatic JIA)`.
Juvenile Spondyloarthritis
This is also called `(Axial Spondyloarthritis).` This type of arthritis affects the spine, hip joints, and `(Entheses)` (the places where tendons and ligaments attach to bones). It can also cause redness and pain in the eyes. It is mainly seen in boys over the age of 7.
Systemic JIA
It is sometimes called `(Juvenile Still's disease)`. About 10% to 20% of children with `(JIA)` have this type. ``Systemic`` means that the whole body or multiple body systems can be affected. In addition to arthritis, systemic `(JIA)` usually causes a persistent high fever and a skin rash . These rashes appear on the trunk, arms, and legs, especially during the fever. It can also affect internal organs such as the heart, liver, spleen, and lymph nodes. This type of `(JIA)` very rarely affects the eyes. It affects both men and women equally.
What are the symptoms of (JIA)?
The symptoms of JIA can vary depending on the type. Common symptoms include:
- Redness, eye pain, and blurred vision (especially if you have uveitis)
- Tiredness or frequent irritability
- Fever (especially in systemic JIA)
- Walking with a limp (due to joint pain)
- Morning joint stiffness (feeling like it's hard to bend your joints when you first wake up in the morning)
- Pain, swelling, or a feeling of warmth in the joints
- Skin rash
- Swollen lymph nodes
- Weight loss or growth failure
Remember, not all of these characteristics are present in every child. Some children may have only a few of them.
What causes (JIA)?
In fact, experts still don't know the exact cause of JIA. The word " idiopathic " means "of unknown cause." However, there are several factors that are thought to contribute to it:
- Environmental factors: Things in the environment that affect the child's immune system.
- Genetic factors: A predisposition that comes from heredity.
- Infections: It is suspected that this condition may occur due to changes in the immune system after certain infections.
What are the possible complications of (JIA) if it is not treated?
If the condition is not treated properly, the child can develop various complications. That is why it is important to diagnose and start treatment early.
- Chronic arthritis and functional impairment: Continuous joint pain and difficulty performing normal activities.
- Inflammation of the membranes surrounding the heart (`Pericarditis`) or inflammation of the membranes surrounding the lungs (`Pleuritis`) .
- Impaired bone and growth in the child.
- Permanent damage to joints.
- Vision problems: especially `(Uveitis)` (inflammation inside the eye) and the resulting vision loss.
How is (JIA) diagnosed?
If your child is suspected of having JIA, this is how a doctor will approach the diagnosis:
- Checking the child's joints.
- Reviewing the child's complete medical history.
- Talking about symptoms with yourself and your child.
There is no specific blood test to diagnose JIA. Therefore, the doctor rules out other conditions and comes to a conclusion that JIA is the cause.
In addition, the doctor may also order tests such as:
- Imaging tests: Tests such as X-rays, ultrasound, or magnetic resonance imaging (MRI) can be used to check the condition of your child's joints.
- Laboratory tests: These can help diagnose the type of arthritis by examining blood, urine, and/or joint fluid and look for other causes such as infection, injury, or cancer.
How is (JIA) treated?
Medication and exercise are usually the mainstays of treatment for `(JIA)`. The main goals of treatment are:
- Increasing mobility and strength in joints.
- Preventing joint damage and complications.
- Pain relief.
- Reducing swelling.
Medications
If your child is diagnosed with JIA, the doctor may prescribe medications such as:
- Nonsteroidal anti-inflammatory drugs (NSAIDs): These medications reduce pain and swelling, but they do not significantly affect the course or outcome of JIA.
- Corticosteroids: Doctors often give this medicine as an injection into a single affected joint. Sometimes, if many joints are affected or if the child has systemic JIA, they also give the steroid as a pill or liquid to take by mouth.
- Disease-modifying anti-rheumatic drugs (DMARDs): These drugs work by changing the disease process of arthritis. The goal of DMARD treatment is to suppress the immune system's attack on the child's bones and joints.
- Biological modifying agents: These drugs target molecules or proteins that cause inflammation. These treatments are often recommended for children with severe symptoms who have not responded to other medications.
Exercise
Exercise (which includes physical therapy and occupational therapy) can help reduce pain, keep muscles strong, improve mobility, and prevent permanent complications. In some cases, a doctor may also use splints or braces to help protect the joints as the child grows.
Can JIA be prevented?
Because doctors don't know exactly what causes JIA, there is currently no way to prevent it. Experts are continuing to research the causes and prevention of JIA.
What is the future for children and young people with (JIA)?
JIA does not affect every child in the same way. For some, it affects only one or two joints and is easily managed. For others, JIA can affect multiple joints and cause severe or long-lasting symptoms.
With early diagnosis and treatment, many children with JIA can control their arthritis, prevent joint damage, and return to normal or near-normal levels of function.
How long does (JIA) last?
JIA can last for months or years. Some children go into full remission, while others may have symptoms well into adulthood. Doctors call this "aging out" of JIA and becoming adult-onset arthritis. There's no way to predict when this will actually happen. But your doctor can help you manage your child's condition, find effective treatments, and help you set a successful future.
When should I see a doctor?
If your child has these symptoms for six weeks or more , you should definitely see a doctor:
- Joint pain
- Joint stiffness
- Swelling around the joints
What advice can you give to children and young people living with (JIA)?
If your child has JIA, encourage them to live as normally as possible. It is important for them to attend school, play sports, participate in extracurricular activities, and participate in family activities. Sometimes doctors recommend special accommodations to help them cope with the limitations of arthritis and schoolwork.
The most important thing to know is that exercise does not make arthritis symptoms worse. In fact, exercise can help prevent deconditioning and increase muscle strength and endurance, which support joints.
When it comes to nutritional needs, there is no evidence that specific meal plans help with arthritis symptoms. Therefore, encourage your child to eat a normal, balanced diet.
As a parent, you want your child to be healthy and free from pain. But being told that your child has JIA can be upsetting, frustrating – and even unfair. Your doctor is here to help. A diagnosis of JIA can feel like a big bump in the road. But with treatment, it’s like a speed bump in the road. It’s normal to feel a little shaky at first. Trust that your doctor can help you manage your symptoms and create a good treatment plan to get your child on the right track.
