Polyartritis means inflammation of more than one joint. This group of autoimmune inflammatory arthritic diseases has many characteristics similar to rheumatoid arthritis but the rheumatoid factor is absent. The changes are not known but genetic features may be involved.
- Ankylosing spondylitis. This tends to occur in young adults,and affects the joints of the vertebral column. Calcification of the intervertebral joints and lying down of new bone leads to reduced spinal flexibility and permanent deformity.
- Psoriatic arthritis. This occurs in a proportion of people who suffer from psoriasis,especially if the nails are involved. The joints most commonly affected are those of the fingers and toes.
- Reiter’s syndrome. This syndrome,it is believed,may be precipitated by infection with Chlamydia trachomatis;the affected joints are usually those of the lower limb.
- Rheumatoid fever. Rheumatic fever is a diffuse inflammatory condition that affects many connective tissues. POLYARTHRITIS is a common presenting feature,often involving the wrists,elbows,knees and ankles. Unlike cardiac effects,arthritis usually resolves spontaneously without complications.
