Background: Changes in patients’ bone mineral density (BMD) is one of the problems in patients with rheumatoid arthritis, which can be due to the use of corticosteroid drugs to reduce patients' symptoms or due to the aging process in patients. In this study, we decided to compare BMD in patients with psoriatic arthritis and rheumatoid arthritis. Methods: This study as a cross-sectional descrip...

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%)...

In March, 1948, Rose and others described a test for rheumatoid arthritis which depended on the ability of serum from patients with rheumatoid arthritis to agglutinate " sensitized " sheep erythrocytes in much higher titre than normal sheep erythrocytes. The authors reported results in 110 patients, of whom 27 had active rheumatoid arthritis and 16 inactive rheumatoid arthritis, 3 Still's disea...

Colonization of Porphyromonas gingivalis in the oral cavity can play an important role in rheumatoid arthritis. The aim of this study was to determine whether there is a relationship between rheumatoid arthritis disease and the presence of P. gingivalis. <stro...
