Juvenile rheumatoid arthritis, also termed as juvenile idiopathic arthritis sometimes, is not uncommon in children. Pain in the joint, stiff joints, and swelling are some of the common presenting complaints.
Constant pain is the major and most bothering symptom. The causes for the pain vary and depend on many factors . Despite low disease activity, many children appear to have hand and/or wrist related symptoms and impairment, with resulting moderate to severe activity limitations and participation at school . Patients present with painful, swollen joints with or without the presence of fever and rash.

Low-grade fever, weight loss, and anemia may occur, as well as growth problems in severe cases. Most children with polyarticular disease are negative for rheumatoid factor and their prognosis is usually good. [arthritis.about.com]
Finally, the condition can also cause weight loss. This can be a direct result of the disease, or it may be a side effect. Because of other symptoms, the child may simply not want to eat, which will naturally result in weight loss. [chronicbodypain.net]
May be associated with weight loss or family history. Malignancy: Night pain, weight loss, easy bruising can all be features. Leukaemia, lymphoma, neuroblastoma, Ewing's sarcoma, bony tumours. [patient.info]

Juvenile rheumatoid arthritis (JRA) causes joint swelling, pain, stiffness and loss of motion. It can affect any joint, and in some cases it can affect internal organs as well. One early sign of JRA may be limping in the morning. [wexnermedical.osu.edu]
MRI MRI shows synovial hypertrophy, joint effusions as well as osseous and cartilaginous erosions. Active synovitis is characterized by enhancement on T1-weighted gadolinium contrast studies. [radiopaedia.org]
It is characterized by joint effusion (an increase in the amount of synovial fluid in the joint) and/or presence of a combination of symptoms including limitation in the range of motion, pain or tenderness associated with joint movement, and increased [rheumatoidarthritis.net]

The most characteristic lesions of rheumatoid arthritis are subcutaneous nodules, which may be present for weeks or months and are most commonly found over bony prominences, especially near the elbow. [medical-dictionary.thefreedictionary.com]

Workup consists of a detailed history and physical examination.
Laboratory tests are not diagnostic but are performed to both confirm the presence of infection and to eliminate the possibility of other diseases.
- Complete blood count
- Erythrocyte Sedimentation Rate
- Serum ANA
- Serum C Reactive Protein assay
- Liver function tests
- Kidney function tests
- Angiotensin Converting Enzyme levels (to rule out sarcoidosis)
Synovial thickness, and volume of effusion monitored by ultrasound is used to examine the progression, and prognosis of the disease . Imaging studies include X-Ray of involved joints, CT scan and MRI (highly sensitive). MRI can give details about the status of soft tissue, cartilage of the joint, synovial membrane, and joint integrity as a whole .
On the basis of physical examination and history and by eliminating all other diseases with the help of laboratory tests, a diagnosis of juvenile rheumatoid arthritis can be made.

It includes non-steroidal antiinflammatory drugs (NSAIDs) and opioids. Counselling plays an important role in the pain management. Physical therapy and psychological interventions are of great benefit for the patient .
Many new drugs have been prepared to help manage rheumatic diseases. They include methotrexate, a DMARD, etanercept  and Tumor Necrosis Factor alpha blockers. Celecoxib has been found effective in one study .
Regular physiotherapy sessions may help improve movement and functioning of the affected joints.
Prognosis depends upon the subtype. Generally, JIA has a good prognosis, provided it is appropriately treated. Polyarticular JIA has the worst prognosis of all subtypes and needs to be treated aggressively to improve patient's health.
Complications of JIA are rarely serious. They mainly involve a restricted life style due to physical impairment of motion. In polyarticular JIA, involvement of internal organs may complicate the disease. Overall, children suffering from JIA have weak bones and muscles and slower growth.
High adiposity: According to a study, patients with severe JIA have high adiposity accompanied by increased bone resorption . Such children become obese and remain short in height.
As the name indicates, JIA has no known etiology. It is an autoimmune reaction which may or may not be triggered by genetic as well as external factors. Whatever the precipitating cause may be, JIA affects young children and usually persists for life.
JIA affects between 8-150 out of every 100,000 children, depending upon the analysis .
JIA may occur anywhere between the 1st year of life to age 16. It is however, more common between 1-3 years of age.
Like other rheumatic diseases, JIA is more common in females.
Juvenile arthritis consists of various conditions that start before the age of 16 years and last for longer than 6 weeks . It may be classified into 3 subtypes. They include:
- Oligoarticular JIA
This subtype is also known as pauci-articular JIA. In this type, there is only involvement of 4 or less than 4 joints. The affected joints are asymmetrical, more often than not affecting just one side of the body. Larger joints are more frequently involved, however, smaller joints such a those of fingers and toes may sometimes become involved as well. High serum ANA levels are a marker for oligo articular JIA.
- Polyarticular JIA
This subtype occurs when there is involvement of 5 or more joints in the first 6 months of development of disease. Large as well as small joints are symmetrically involved and there is even involvement of the jaw and neck. Due to the aggressiveness of this subtype, prognosis is worse.
- Systemic JIA
In this subtype, as the name indicates, there are systemic signs of infection and inflammation such as fever, maculopapular rash on the trunk and extremities as well as both large and small joint involvement. Internal organs may become involved, commonly hepatosplenomegaly occurs. The fever and rash come and go making diagnosis difficult. Serum ANA levels are also low.
Juvenile rheumatoid arthritis (JRA) is the most common cause of chronic rheumatic disease in childhood . It is an autoimmune, noninfective condition in which inflammation of one or more joints occurs at an early age. This name, JRA, has been replaced by the more appropriate term: Juvenile idiopathic arthritis (JIA).
Juvenile rheumatoid arthritis (JRA), also known as JIA, is inflammation of at least one joint that persists for at least 6 weeks, even after other causes are excluded, in an individual younger than 16 years.
JRA presents with pain and swelling of a joint, most commonly the knee, elbow, wrist and ankle joint. Pain and swelling are accompanied with stiffness and restricted movement, and sometimes there may be presence of rash on the trunk and extremities, and fever.
Immunosuppressive medications and painkillers taken along with physiotherapy can help relieve symptoms.
