Juvenile rheumatoid arthritis

Description

A habitual, seditious complaint that may beget common or connective towel damage. The onset occurs before age 16. Indispensable names Juvenile habitual polyarthritis; JRA; Still’s complaint Causes, prevalence, and threat factors JRA is allowed to belong to the collagen classes of complaint( those conditions that involve connective towel). It’s a complicated complaint.

The primary incarnation is arthritis, but the complaint may involve other body systems similar as the heart and lining around the heart( pericardium), lungs and lining around the lungs( pleura), eyes, and skin. Systemic arthritis affects 20 of those with juvenile arthritis and includes fever, rash, and enlarged spleen( splenomegaly) in addition to common inflammation.

JRA is generally divided into five broad groups depending on whether a large number of joints are involved or just a many, whether the rheumatoid factor( a blood test) is positive or negative, and whether there’s eye involvement or not. The five orders of JRA may be roughly broken down as follows numerous involved joints and a positive rheumatoid factor numerous involved joints and a negative rheumatoid factor many involved joints and a positive antinuclear antibody many involved joints and a positive HLA B27 face antigen systemic JRA( throughout the body) The order determination is generally made by a specialist in rheumatology. The onset of arthritis may be slow or extremely rapid-fire.

An early sign of slow onset may be stiffness on arising in the morning. The arthritis of JRA is characterized by blown painful joints with pain on stir and occasionally to touch. The skin over the joints is generally not red, but it can be. The systemic form of JRA may first appear with high complications, chills and a rash but without joint pain. In the systemic form, arthritis may develop months after the appearance of the fever. The two forms of JRA where there are only a many joints involved frequently have associated eye complaint.

The most severe form of eye complaint, habitual iridocyclitis of JRA, may lead to visual problems or blindness. The milder form of JRA- associated eye complaint is acute iridocyclitis, which generally heals without endless damage. The cause of juvenile rheumatoid arthritis is unknown. Growth may be affected during ages of active complaint. Girls are affected more frequently than boys. The peak onset occurs between the periods of 2 to 5 times old and between 9 to 12 times old. threat factors may be a family history of the complaint and recent rubella infection or vaccine.
