HLA-DRβ2 and IgM Rheumatoid Factor (RF) Positive Rheumatoid Arthritis (RA)

International Journal of Immunopathology and Pharmacology, 1988
48 patients suffering from classic erosive RA with conditions persisting for more than 6 years were examined together with 69 healthy control subject with regard to associations to supertypic HLA-D specificities. We found a significant increase of HLA-DRw53 in patients with RF positive RA (22/31 pat. = 71%,Chi2 = 13.2, p<0.01).

1023 IgA RHEUMATOID FACTOR (RF) IN HENOCH-SCHONLEIN PURPURA (HSP) [PDF]

Pediatric Research, 1985
Recent evidence indicates that circulating immune complexes play a role in the pathogenesis of HSP. The elaboration of RF appears to be an important host response to circulating immune complexes. Accordingly, sera from 23 children with acute HSP were tested for RF of various isotypes using a diffusion-in-gel enzyme-linked immunosorbant assay.

Multicentre study to improve clinical interpretation of rheumatoid factor and anti-citrullinated protein/peptide antibodies test results

RMD Open, 2022
Background Rheumatoid factor (RF) and anti-citrullinated protein/peptide antibodies (ACPA) are important biomarkers for diagnosis of rheumatoid arthritis (RA). However, there is poor harmonisation of RF and ACPA assays.

Gambaran Kadar Rheumatoid Factor (Rf) Pada Wanita Menopause

Jurnal Kesehatan Rajawali, 2022
Menopause occurs in women aged between 40-55 years. Decreased levels of the hormone estrogen at the time of menopause will interfere with calcium absorption so that bones become brittle. Cells that experience inflammation will cause the entry of antibodies into the space between the bones.

Use of Cerebrospinal Fluid Biomarkers in Diagnosis and Monitoring of Rheumatoid Meningitis

Frontiers in Neurology, 2019
Rheumatoid meningitis is a rare extra-articular manifestation of rheumatoid arthritis, often with non-specific symptoms. In most cases brain MRI shows a patchy lepto- and pachymeningeal enhancement, but the diagnosis currently relies on examination of a ...
