Antinuclear Factor in Rheumatoid Arthritis, Its Incidence and Clinical Significance.
The antinuclear factor (ANF) test has been used in the diagnosis of systemic lupus erythematosus (SLE) for some years since it was first described in 1957 (Friou, Finch, and Detre, 1957; Holborow, Weir, and Johnson, 1957) and in this Unit it has been positive in every case of clinically active lupus erythematosus tested. ANF has also been found in the sera in some cases of rheumatoid arthritis ...
متن کاملPositivity for antinuclear antibody in patients with advanced rheumatoid arthritis.
Some patients with rheumatoid arthritis (RA) as well as those with other collagen diseases are positive for antinuclear antibody (ANA). We investigated the frequency of positivity for ANA in 104 patients with RA and evaluated the clinical features and laboratory data in the ANA-positive and -negative groups. The presence of ANA in sera was studied by indirect immunofluorescence using HEp-2 cell...
متن کاملAntinuclear factors in rheumatoid arthritis. Increasing organ-non-specificity with increasing reactivity of rheumatoid factor with heterologous gamma globulin.
McCormick and Day (1963) reported that rheumatoid factors and 7S ANF co-existing in the same seramayform high molecular weight complexes, and absorption studies have brought forward evidence of an interaction between ANF and rheumatoid factors when present in the same serum (Holborow and Johnson, 1965). However, ANF in rheumatoid arthritis have mostly been found in low frequency and chiefly in ...
متن کاملAntinuclear antibody and rheumatoid factor in silica-exposed workers.
A lot of workers in industries such as foundry, stonecutting, and sandblasting are exposed to higher than permissible levels of crystalline silica. Various alterations in humoral immune function have been reported in silicosis patients and workers exposed to silica dust. The aim of this study was to measure antinuclear antibody (ANA) and rheumatoid factor (RF) levels in foundry workers exposed ...
متن کاملCirculating antinuclear antibody and rheumatoid factor in coal pneumoconiosis.
Circulating antinuclear antibody and rheumatoid factor have been measured in 109 coal miners with pneumoconiosis whose chest radiograph showed a range of abnormalities varying from simple pneumoconiosis of mild degree to advanced progressive massive fibrosis.At a screening dilution of 1/10 the overall incidence of antinuclear antibody was 17%. In almost half of the positive cases the titre was ...
