What organs are affected by juvenile rheumatoid arthritis?

What organs are affected by juvenile rheumatoid arthritis?

Although JIA mostly affects the joints and surrounding tissues, it can also affect other organs, like the eyes, liver, heart, and lungs. JIA is a chronic condition, meaning it can last for months and years.

What is polyarticular juvenile rheumatoid arthritis?

Polyarticular juvenile idiopathic arthritis (formerly called polyarticular-onset juvenile rheumatoid arthritis [RA]) is a subset of juvenile idiopathic arthritis (JIA) that is defined by the presence of more than four affected joints during the first six months of illness [1].

What specific part of the body is affected by rheumatoid arthritis?

Unlike the wear-and-tear damage of osteoarthritis, rheumatoid arthritis affects the lining of your joints, causing a painful swelling that can eventually result in bone erosion and joint deformity.

What joints are affected by JRA?

It typically affects large joints, such as the knees. Girls under age 8 are most likely to develop this type of JRA. Some children with pauciarticular JRA have abnormal proteins in the blood called antinuclear antibodies (ANAs).

What is polyarticular arthritis?

Polyarthritis (also known as polyarticular arthritis or inflammatory polyarthritis) is defined as arthritis or joint pain that affects five or more joints simultaneously. 1. The term itself simply describes the number of joints involved: poly means many.

What is the difference between rheumatoid arthritis and juvenile arthritis?

JIA is arthritis that affects one or more joints for at least 6 weeks in a child age 16 or younger. Unlike adult rheumatoid arthritis, which is ongoing (chronic) and lasts a lifetime, children often outgrow JIA. But the disease can affect bone development in a growing child.

What is polyarticular osteoarthritis?

What does polyarticular mean?

Polyarticular: Involving many joints, as opposed to monoarticular (affecting just one joint).

What joints are most commonly affected by rheumatoid arthritis?

Key Points about Rheumatoid Arthritis The joints most often affected by RA are in the hands, wrists, feet, ankles, knees, shoulders, and elbows. Symptoms may include joint pain, stiffness, and swelling; decreased and painful movement; bumps over small joints; and fatigue or fever.

What is asymmetric arthritis?

ANSWER. Asymmetric arthritis typically involves one to three joints in the body — large or small — such as the knee, hip, or one or several fingers. Asymmetric psoriatic arthritis does not affect matching pairs of joints on opposite sides of the body.

Can Juvenile Arthritis be misdiagnosed?

JIA can be mistaken for growing pains or an injury, and understandably, parents may wait it out to see if it gets better. Kids may have swollen joints, sore wrists or knees, and stiffness. They may even limp because of the swelling or pain.

Is juvenile arthritis the same as rheumatoid arthritis?

What is polyarticular juvenile rheumatoid arthritis (JRA)?

Polyarticular juvenile rheumatoid arthritis: Children who have five or more joints involved with arthritis during the first six months of their disease are classified into the polyarticular JRA form of illness. Two subgroups of polyarticular JRA exist based upon a constellation of various laboratory studies.

What is polypolyarticular ja?

Polyarticular JA is separated into two categories, distinguished by the presence or absence of rheumatoid factors. Rheumatoid factors are proteins produced by the immune system that can damage healthy tissues that make up body joints.

What is the prevalence of eye disease in children with pauciarticular JRA?

Eye disease affects from 20% to 30% of children with pauciarticular JRA and is more common in children with abnormal ANAs.

What are the possible complications of juvenile rheumatoid arthritis?

Knowledgeable specialists (pediatric rheumatologists usually affiliated with pediatric teaching hospitals) can help to limit the possibility of complications of juvenile rheumatoid arthritis including leg-length discrepancy, joint contractures, and destruction and blindness due to inflammation of the eye ( iritis ).
