Antinuclear antibodies (ANA) are antibodies that bind to several nuclear antigens. ANA have been reported in cancers, suggesting that they may have a role in the pathogenesis of malignancy [4,5]. Many studies have reported that NHL patients could display ANA antibodies [6,7]. This study assessed serum levels of ANA in NHL patients and examined its association with hematological, clinicopatholog...

Objective: Although osteoarthritis (OA) is widely accepted as a degenerative disease, autoimmune processes are believed to be involved in the pathogenesis. There are limited studies in this area and most of them focused on antibodies against chondrocyte membrane. In an attempt to address the paucity of evidence in this regard, we explored the clinical significance of antinuclear antibody (ANA) ...

OBJECTIVE Antinuclear antibody (ANA) analysis by immunofluorescence (IF) microscopy remains a diagnostic hallmark of systemic lupus erythematosus (SLE). The clinical relevance of ANA fine-specificities in SLE has been addressed repeatedly, whereas studies on IF-ANA staining patterns in relation to disease manifestations are very scarce. This study was performed to elucidate whether different st...

OBJECTIVE To evaluate the frequency of clinical and laboratory manifestations in patients with primary antiphospholipid syndrome (PAPS) with positive antinuclear antibodies (ANA Hep-2+) compared to those in whom this antibody is negative (ANA Hep-2-). PATIENTS AND METHODS This is a transversal study with 58 patients (82.8% females) with PAPS. Demographic and clinical data, comorbidities, medi...

OBJECTIVES To assess the clinical value of several serological markers in Lithuanian patients with rheumatoid arthritis (RA) compared with control patients with rheumatic disease and age matched healthy controls. METHODS Serum samples from 96 patients with RA of approximately 8 years' duration, 90 rheumatic disease controls, and 37 healthy subjects were tested. Antikeratin antibody (AKA), ant...

Kikuchi Fujimoto Disease (KFD), also known as necrotic histiocystic lymphadenitis, is a condition with unknown etiology. Probably, infectious, viral, and also autoimmune etiologies, especially lupus erythematosus, contribute to this disorder. The common signs are lymphadenopathy along with fever and leukopenia. Our case was a13-year-old boy with fever of unknown origin. He underwent ordinary fe...

Studies on autoantibody production in patients treated with tumor necrosis factor-alpha (TNF-alpha) inhibitors reported contradictory results. We investigated in a prospective study the efficacy of a treatment with human monoclonal anti-TNF-alpha antibody (adalimumab) in patients with rheumatoid arthritis (RA) and we evaluated the relationship between treatment efficacy and the incidence and ti...

BACKGROUND The gold standard for antinuclear antibody (ANA) screening is the indirect immunofluorescence (IIF) assay with human epithelial cells (HEp-2). However, a number of substantial disadvantages of manual IIF assays have highlighted the need for the automation and standardization of fluorescent ANA (FANA) testing. We evaluated the performance of EUROPattern Suite (Euroimmun AG, Germany), ...

OBJECTIVE To study the sera from selected groups of antineutrophil cytoplasmic antibody (ANCA) positive patients by means of the indirect immunofluorescence test (ANCA-IIF) with different fixatives, in order to better discriminate among the various ANCAs (Ag-specificity and disease associations), especially those for which the antigen targets have not yet been identified. METHODS Eighty patho...
