Rheumatoid arthritis - a disease that has its basis in immunopathological processes and characterized by a greater proportion of patients with chronic systemic connective tissue lesions predominantly musculoskeletal.
There are two main forms of rheumatoid arthritis:
articular
joint and visceral
several variants of each.
Articular form develops gradually, accompanied by a slight worsening outbreaks of severe febrile reaction without, without signs or symptoms with poorly defined internal organ, with the rare appearance of hives and other symptoms of allergic conditions.
Changes in the joints in this form has the character of mono-or oligoarthritis. In the pathological process often involved the knee, then ankle, small joints of the hand, wrist, elbow and all the other relatively rare joints. In the affected joints is typical assimitriya. Local events are characterized by changes in the shape of the joint, rise in temperature over the joint, limitation of function, muscle wasting respective limb.
Relatively frequently (20%) at the articular form of rheumatoid arthritis develops rheumatoid uveitis. In the pathological process involved a capsule eye svetprelomlyayuschie environment and vascular tract - there iritis or iridocyclitis, less horeoidit or defeat of all three divisions of the choroid - uveitis. As secondary effects attached ribbon-like corneal dystrophy, cataract.
Triad of symptoms (iridocyclitis, cataract and corneal dystrophy) is considered typical for children of rheumatoid arthritis. During the joint shape (with the exception of rheumatoid uveitis) relatively favorable.
Articular-visceral form (boleznStilla) - the most severe form of rheumatoid arthritis in children. It is characterized by acute onset and rapid development, high fever, massive articular syndrome, severe reaction to the lymphoid organs and liver vistseritami (myocarditis, pericarditis, pleurisy, etc.). Defeat of joint multiple, symmetric, sometimes all the affected joints.
