Rheumatoid polyarthritis after rubella.

Significance of rubella virus infection in juvenile chronic polyarthritis.

Fifty-three patients under the age of 5 years with definite juvenile chronic polyarthritis (JCP) were examined for serological evidence of rubella infection. The prevalence of rubella antibody was found to be low and did not differ significantly from that found in normal children of similar age. Patients with JCP and antibody to rubella virus had a clinical course indistinguishable from those w...

Symmetrical polyarthritis is not always rheumatoid.

Rubella virus and rheumatoid arthritis.

A collection of synovial fibroblasts from 19 patients with rheumatoid arthritis (RA) and 12 patients with osteoarthrosis or other non-RA disease has been examined for rubella virus antigens by immunofluorescence and radioimmunoassay with negative results. Eluates of synovial membrane prepared under conditions likely to dissociate antigen-antibody complexes have shown no rubella antibody. A sero...

Rubella antibody levels in juvenile rheumatoid arthritis.

Increased rubella antibody titres have been reported in patients with juvenile rheumatoid arthritis (JRA) and it has been suggested that rubella virus may be of importance in the aetiology or pathogenesis of the disease. In the present study, rubella and rubeola antibody titres in 85 patients with JRA were compared to age- and sex-matched controls. 41% of the patients did not have rubella antib...
