Juvenile Idiopathic Arthritis (JIA) also referred to as Juvenile Rheumatoid Arthritis (JRA) is the most common form of arthritis found in children  (ages 0-16)

Arthritis can be most simply defined as inflammation in the joints

The exact cause is still unknown but studies show that it is an autoimmune disorder, meaning our own bodies' immune system triggers inflammation in the body that leads to arthritis

About 1 in 1,000 children are diagnosed with a varying type of chronic arthritis

# data[].attributes.body
Doctors use physical symptoms, family history and sometimes a blood test (not all children test positive) checking for Rhuematoid factor

Symptoms include but are not limited to:
-Morning joint stiffness that can improve with activity
-Joint Swelling
-Excessive Clumsiness
-Fatigue
-Limping (knees are the most commonly affected)
-Difficulty writing or opening containers requiring twisting (due to pain in the joints of hands)

-Physical activity is crucial in keeping joints healthy.
-Regular activity strengthens the muscles around joints. These muscles support the joint and keep them working the way they should.
-Even those already diagnosed with arthritis should incorporate regular exercise. This is especially true for kids, as establishing good lifestlye habits is important in early age.
-Children and teenagers should get 60 minutes or more of physical activity each day.
-When exercising or playing sports, be sure to wear the proper protective equipment to avoid injuring your joints.
Don't forget stretching and warming up before exercise

OVERVIEW, SYMPTOMS, & CAUSES

Like adults, children can develop arthritis. The most common type of chronic, or long-lasting, arthritis that affects children is called juvenile idiopathic arthritis (JIA). JIA broadly refers to several different chronic disorders involving inflammation of joints (arthritis), which can cause joint pain, swelling, warmth, stiffness, and loss of motion. The various forms of JIA have different features, such as the pattern of joints involved and inflammation of other parts of the body besides the joints. JIA may last a limited time, such as a few months or years, but in some cases it is a lifelong disease that requires treatment into adulthood.

JIA is “idiopathic,” meaning that its origins are not understood. While the exact causes of JIA are unknown, it begins when the immune system becomes overactive and creates inflammation.

With treatment, most children achieve periods of wellness (remission), and sometimes the disease goes away permanently with no further need for medications. It is important to see a doctor early if your child has swollen or stiff joints because delaying therapy can lead to joint damage, a lesser response to treatment, and other problems.

Who Gets Juvenile Idiopathic Arthritis (JIA)?

By definition, JIA begins in children and adolescents before the 16th birthday. Most types of the disease are more frequent in girls, but enthesitis-r elated JIA, a form of the disease that involves inflammation of the places where ligaments and tendons (flexible bands of tissue) attach to bones, is more common in boys. Systemic JIA, a rare type of JIA that features fever and rash, affects boys and girls equally. Children of all races and ethnic backgrounds can get the disease.

It is very rare for more than one member of a family to have JIA, but children with a family member with chronic arthritis, including JIA, are at a slightly increased risk of developing it. Having a family member with psoriasis is a risk factor for a form of JIA called psoriatic JIA.

Types of Juvenile Idiopathic Arthritis (JIA)

There are multiple types of JIA, each with distinct features. Generally, they all share arthritic symptoms of joint pain, swelling, warmth, and stiffness that last at least 6 weeks.

The types are:

Oligoarticular juvenile idiopathic arthritis. This is the most common and mildest form, affecting four or fewer joints. It is considered persistent if symptoms continue for 6 months or longer, and extended if five or more joints become involved after 6 months of illness. Commonly affected joints are knees or ankles. A form of eye inflammation called chronic (long-lasting) uveitis can develop in children with this form of JIA. About half of children with JIA have this type.

Polyarticular juvenile idiopathic arthritis–rheumatoid factor negative. This is the second most common type, affecting five or more joints in the first 6 months. Tests for rheumatoid factor are negative. The rheumatoid factor blood test checks for autoimmune disease, especially rheumatoid arthritis, which is an adult form of arthritis. Some of these children develop chronic uveitis.

Polyarticular juvenile idiopathic arthritis–rheumatoid factor positive. A child with this type has arthritis in five or more joints during the first 6 months of the disease. Tests for rheumatoid factor, a marker for autoimmune disease, are positive. It tends to occur in preteen and teenage girls, and it appears to be essentially the same as adult rheumatoid arthritis.

Enthesitis-related juvenile idiopathic arthritis. This form of JIA involves both arthritis and enthesitis. Enthesitis happens when inflammation occurs where a ligament or tendon attaches to a bone. The most common locations for enthesitis are the knees, heels, and bottoms of the feet. Arthritis is usually in the hips, knees, ankles, and feet, but the sacroiliac joints (at the base of the back) and spinal joints can also become inflamed. Some children get episodes of acute anterior uveitis, a sudden onset of inflammation of the front of the eye. Unlike most other forms of JIA, enthesitis-related JIA is more common in boys.

Psoriatic juvenile idiopathic arthritis. Children with this type have psoriasis, a skin condition, as well as inflammation of the joints. The skin condition usually appears first, but sometimes painful, stiff joints are the first sign, with the skin disease occurring years layer. Pitted fingernails and dactylitis (swollen fingers or toes) are also signs of the disease.

Systemic juvenile idiopathic arthritis. Systemic means the disease can affect the whole body, not just a specific organ or joint. Systemic JIA usually starts with fever and rash that come and go over the span of at least 2 weeks. In many cases, the joints become inflamed, but sometimes not until long after the fever goes away, and sometimes not at all if treatment is started quickly. In severe forms, inflammation can develop in and around organs, such as the spleen, lymph nodes, liver, and linings of the heart and lungs. Systemic JIA affects boys and girls with equal frequency.

Undifferentiated arthritis. This category includes children who have symptoms that do not fit into any of the other types or that fit into more than one type.

Symptoms of Juvenile Idiopathic Arthritis (JIA)

Symptoms of JIA vary depending on the type, but all forms share persistent joint pain, swelling, warmth, and stiffness that are typically worse in the morning and after a nap or prolonged sitting. The pain may limit movement of the affected joint, although many children, especially younger ones, will not complain of pain. One of the earliest signs may be limping in the morning due to disease in one or both legs.

The symptoms of JIA may go through cycles, flaring for a few weeks or months followed by periods when they go into remission. Some children have just one or two flares and never have symptoms again, while others have many flares or symptoms that never fully go away.

Besides joint problems, the inflammation associated with JIA can cause other symptoms, such as:

Eye inflammation. Uveitis (inflammation of the front and middle parts of the eye) often occurs in children with JIA. It usually starts within a few years after the JIA diagnosis, but in a small fraction of children, it appears before the joint symptoms or many years afterward. The type of JIA a child has may cause the development of different types of uveitis. Children with:

Oligoarticular JIA, especially when it begins at an early age, can have chronic (long-lasting) uveitis that has mild or no symptoms. Children with polyarticular JIA without rheumatoid factor, or with psoriatic JIA are also at risk.

Enthesitis-related JIA and some children with psoriatic JIA can have episodes of acute anterior uveitis, which has a sudden onset and causes eye pain, eye redness, and sensitivity to light.

If left untreated, uveitis can lead to eye problems such as cataracts, glaucoma, and vision loss, so it is important for children with JIA to have frequent eye exams.

Skin changes. Depending on the type of JIA a child has, he or she may develop skin changes. Children with:

Systemic JIA who have fevers can get a light red or pink rash that comes and goes.

Psoriatic JIA can develop scaly red patches of skin. Psoriatic JIA can also cause pitted nails and dactylitis (swollen fingers or toes).

Polyarticular JIA with rheumatoid factor can get small bumps or nodules on parts of the body that receive pressure, such as from sitting.

Fever. Patients with systemic JIA typically have daily fevers when the disease begins or flares. The fever usually appears in the evening, and the rash may move from one part of the body to another, usually happening with the fever. Patients with other types of JIA do not generally develop fevers.

Growth problems. Inflammation in children with any type of JIA can lead to growth problems. Depending on the severity of the disease and the joints involved, bones near inflamed  joints may grow too quickly or too slowly. This can cause one leg or arm to be longer than the other, or can result in a small or misshapen chin. Overall growth also may be slowed if the disease is severe. Growth normally improves when inflammation is well-controlled through treatment.

Cause of Juvenile Idiopathic Arthritis (JIA)

In JIA, the body’s immune system—which normally helps to fight off infections and heal cuts and wounds—mistakenly attacks some of its own healthy cells and tissues. The result is inflammation, marked by pain, swelling, warmth, and stiffness. Inflammation from JIA can damage the joints, eyes, or other affected organs.

Scientists do not know why the immune system attacks healthy tissues in children with JIA, but they believe that a complex mix of genes and environmental factors are involved.

While the origin of the immune system’s overreaction in JIA is unknown, scientists have identified some of the molecules that contribute to inflammation in some forms of the disease. We now know that three molecules—TNF-alpha, IL-6, and IL-1—are involved in creating inflammation in the joints of many children with JIA. This has led to new therapies that specifically target these molecules.
