New rheumatoid arthritis genetic factor and C5 serum level

Annals of the Rheumatic Diseases, 2009
There is a significant body of evidence suggesting that complement activation plays an important role in the maintenance of the polyarticular chronic synovitis characteristic of rheumatoid arthritis (RA).1 Recently, a novel RA genetic risk factor was described, involving allelic polymorphisms on the chromosome 9, in the intergenic region between ...

Studies on the Rheumatoid and Related Serum Factors

JAMA, 1960
Waaler 1 and Rose and co-workers 2 made the puzzling observation that the sera of patients with rheumatoid arthritis agglutinated sheep red cells sensitized by subagglutinating doses of rabbit anti-sheep hemolysin. Although this mystery has not been completely elucidated as yet, great progress has been made.

A Case of Pseudoelevation of Serum HCG Caused by Rheumatoid Factor

Clinical Laboratory
Serum human chorionic gonadotropin (HCG) is a glycoprotein hormone secreted by the trophoblast cells of the placenta. HCG levels are helpful in confirming and monitoring pregnancy, as well as in the diagnosis and monitoring of trophoblastic tumors.

The Relationship between Rheumatoid “Factor” and Serum Desoxyribonucleic Acid

The Journal of Immunology, 1964
Summary A series of experiments undertaken to elucidate the identity of the rheumatoid “factor” present in the serum of rheumatoid arthritics have shown that this substance closely resembles desoxyribonucleic acid. In vitro DNA appears to complex with a Cohn IV-4 globulin and a Cohn Fraction III globulin.

Relationship of serum IgG rheumatoid factor to IgM rheumatoid factor and disease activity in rheumatoid arthritis.

The Journal of rheumatology, 1986
Rheumatoid factors (RF) constitute the major autoantibodies in rheumatoid arthritis (RA). RF are directed against IgG Fc, are polyclonal, and are predominantly of the IgG and IgM classes. RF may participate in both synovial and extraarticular inflammation in RA, although the precise roles of serum IgG and IgM RF are unclear.

A simple radioactive binding assay for the detection of rheumatoid factor in serum

Journal of Immunological Methods, 1980
A simple radioactive binding assay for the detection of rheumatoid factor (RF-RBA) is described. Test sera are complement inactivated by incubation in 0.13 M ethylene diaminetetraacetic acid (EDTA) at 37 degrees C and then incubated with 125I-labelled heat-aggregated IgG.
