The roles of antinuclear and DNA antibodies in the pathogenesis of cryptogenic fibrosing alveolitis were investigated in 53 patients. Twenty-two patients who had antinuclear antibodies detected in their serum had a significantly higher proportion of women, a higher prevalence of Raynaud phenomenon and digital vasculitis, and higher erythrocyte sedimentation rates, paralleled by raised serum glo...
several studies reported the appearance of asthma and autoimmune conditions in the same patient, but the clinical significance of this association was not yet assessed. one hundred asthmatic patients were observed for one year evolution with death, severe exacerbations, intake of > 1000 micrograms of beclometasone or equivalent (high ics) and fev1 decline >100 ml, in relation with ana (elisa), ...
Granulocyte-specific antinuclear antibodies (GS-ANA) were detected in the sera of 5 of 88 patients with ankylosing spondylitis (AS) and in 7 of 52 cases of psoriatic arthritis (PsA), but were not found in 91 patients with malignant or non-malignant chest disease nor in 25 cases of psoriasis. Organ non-specific ANA were present in serum from 6 cases of AS and 1 of PsA. None of the sera gave sign...
Two immunofluorescence procedures to evaluate antinuclear antibodies were compared in a series of 221 patients with chronic liver disorders of various aetiologies. The use of HEp-2 cells allowed us to discriminate with more confidence between the homogeneous and speckled patterns, to show the presence of associated patterns in the same serum, and, above all, to identify two specificities, unrec...
alkylhydroperoxide reductase (ahpc, the 26 kda antigen) is one of the abundant antioxidant enzymes in helicobacter pylori and seems to have a good potential for use in development of immunoassays to detect h. pylori infection in clinical specimens. this study aimed to investigate some properties of this antigen by the produced monoclonal antibodies. five established hybridoma cell lines secreti...
OBJECTIVE To investigate patients with cancer for the frequency of IgG and IgM aCL and ANA in comparison to a group of age- and sex-matched controls. METHODS Serum levels of IgG and IgM anticardiolipin antibodies (aCL), antinuclear antibodies (ANA) and anticytoplasmic antibodies were evaluated in 145 cancer patients, including 20 patients with thromboembolic disease (TED) and compared with ag...
OBJECTIVES Autoantibodies to the dense fine speckled 70 (DFS70) antigen are common among antinuclear antibodies (ANA) positive healthy individuals (HI). We assessed the prevalence of anti-DFS70 antibodies in patients with and without ANA-associated rheumatic diseases (AARDs) by two methods: chemiluminescent immunoassay (CIA) and an indirect immunofluorescence (IIF) assay based on immunoadsorpti...
