Antinuclear antibodies (ANA) were found in 54 (7.0%) out of 767 treated hypertensive patients compared with 59 (2.4%) out of 2470 healthy controls. Inclusion of a non-practolol beta-blocker in the treatment regimen did not significantly affect the incidence of ANA. ANA was found in significantly more patients being treated with methyldopa (13.0%) than patients receiving other hypotensive agents...

BACKGROUND The incidence of autoimmune diseases such as systemic lupus erythematosus, rheumatoid arthritis, and primary biliary cirrhosis has increased significantly in China. Information about the susceptibility or potential of autoimmune diseases in the general population is lacking. OBJECTIVE To explore the prevalence of antinuclear antibody (ANA) and its specificities in the general popul...

INTRODUCTION Patients with AIDS (acquired immunodeficiency syndrome) may have rheumatic complaints such as arthritis and arthralgia, dry eyes, increased salivary glands, lower back pain, enthesitis etc. Autoantibodies like ANA (antinuclear antibody) and RF (rheumatoid factor) may also be present. OBJECTIVE To study the prevalence of rheumatic complaints in AIDS patients and correlate them wit...

The antinuclear antibody test (ANA) is a much overused test in pediatrics. The ANA does have a role in serologic testing but it should be a very limited one. It is often ordered as a screening test for rheumatic illnesses in a primary care setting. However, since it has low specificity and sensitivity for most rheumatic and musculoskeletal illnesses in children, it should not be ordered as a sc...

Current clinical practice relies heavily on serologic testing for the prompt and accurate diagnosis of rheumatic diseases. Serologic testing should be used to support the findings of the history and physical examination, and, in some cases, to monitor disease activity. The inflammation of the rheumatoid arthritis (RA), polymyalgia rheumatica, and temporal arteritis can be assessed by the erythr...

OBJECTIVE To provide data on (a) the probability of detecting antinuclear antibodies (ANA) in a large and consecutive cohort of serum samples referred for ANA testing and (b) the probability of detecting more specific antinuclear reactivities (anti-DNA and anti-extractable nuclear antigens (anti-ENA)) in serum samples with a positive screening test (indirect immunofluorescence on HEp-2 cells). ...

March 01, 2004 ABSTRACT: The basic screening studies for rheumatic diseases are a complete blood cell count, a determination of the erythrocyte sedimentation rate (ESR) or C-reactive protein (CRP) level, a rheumatoid factor assay, an antinuclear antibody (ANA) test, a measurement of serum uric acid level, and a urinalysis. Test results must be interpreted within a clinical context; for example,...

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...

Chronic ulcerative stomatitis (CUS) is a mucocutaneous disease primarily involving mucosal surfaces, but occasionally may involve the skin. Clinically, CUS patients exhibit erosive or ulcerative lesions of the oral mucosa that resemble erosive oral lichen planus. Direct immunofluorescence (DIF) studies of mucosal or skin biopsies reveal a unique pattern of IgG immunoglobulin bound to nuclei of ...
