1. Genetic Factors of Rheumatoid Arthritis

Genetic studies of rheumatoid arthritis

Rheumatoid arthritis (RA) is a common autoimmune disease that results in significant morbidity. As with other complex disorders, genome-wide association studies (GWASs) have greatly contributed to the current understanding of RA etiology. In this review, we describe the genetic configuration of RA as revealed primarily through GWASs and their meta-analyses. In addition, we discuss the pathologi...

Rheumatoid factors specific for active rheumatoid arthritis.

To measure rheumatoid factors specific for patients with rheumatoid arthritis an enzyme linked immunosorbent assay (ELISA) was developed to measure rheumatoid factors in human serum that bind a cross-reactive determinant shared on human and other mammalian IgG. Rheumatoid factors that cross link human IgG and sheep IgG in a double binding ELISA were almost completely specific (greater than 99%)...

Rheumatoid factors in patients with rheumatoid arthritis.

180 Canadian Family Physician • Le Médecin de famille canadien d VOL 52: FEBRUARY • FÉVRIER 2006 I is important for family physicians to understand the role of rheumatoid factor (RF) in management of patients with rheumatoid arthritis (RA). Rheumatoid factors are antibodies that recognize the Fc portion of IgG molecules as their antigens; RFs can be of any immunoglobulin isotype (IgM, IgG, IgE)...
