Background: Detection of antinuclear antibody (ANA) is used as one of the diagnostic criteria for autoimmune rheumatic diseases (ARD). Both indirect immunofluorescence (IIF) and enzyme linked immunosorbant assay (ELISA) methods are used for this purpose. However, there are lack of data comparing these two tests from India. Methods: We prospectively studed 294 patients clinically suspected to be...

SLE is the commonest connective tissue disease encountered in clinical practice. It is a multisystem disorder which can involve the skin, mucous membranes, joints, lungs, kidneys, central and/or peripheral nervous system, heart, and the gastrointestinal system. Constitutional features of fever, fatigue, anorexia and weight loss are common. Lupus should be suspected in the following clinical set...

OBJECTIVE The presence of antinuclear antibodies (ANA), directed against intracellular antigens, is a distinctive feature of systemic autoimmune rheumatic diseases (SARDs). The standard test for antinuclear antibody screening is the indirect immunofluorescence (IIF). Anti-dense fine speckled 70 (anti-DFS70) antibodies were initially identified as an ANA IIF pattern from a patient with interstit...

The presence of viruses was sought in a colony of dogs bred from parents with systemic lupus crythematosus (SLE). Cell-free filtrates prepared from the spleens of these animals were injected into newborn dogs, mice, and rats. The canine recipients developed antinuclear antibody (ANA) and positive lupus erythematosus (LE) cell tests: ANA and, in some cases, antinative DNA antibodies were produce...

Pumas (Puma concolor; also known as mountain lions and cougars) in southern California live among a burgeoning human population of roughly 20 million people. Yet little is known of the consequences of attendant habitat loss and fragmentation, and human-caused puma mortality to puma population viability and genetic diversity. We examined genetic status of pumas in coastal mountains within the Pe...

The following guideline presents a series of recommendations based on published medical literature for use of the antinuclear antibody (ANA) test and tests for specific autoantibodies to nuclear antigens in the diagnostic evaluation, prognostic assessment, and monitoring of patients with systemic rheumatic diseases. The guideline emphasizes the need for clinical evaluation to improve the useful...

AIMS To analyze the prognostic role of antinuclear antibodies (ANA) for the onset of uveitis in the context of juvenile idiopathic arthritis (JIA), its correlation with uveitis course and severity and its prognostic role for the development of arthritis in children with uveitis. METHODS We conducted a systematic review analysis of the literature on the prognostic value of ANA on JIA associate...

Estimations of human exposure levels to aromatic nitroand amino-compounds (ANA) are often made by Bratton-Marshall's diazo reaction. In Japan, the environmental conditions of the ANA industries have recently improved remarkably. The workers in ANA plants excrete somewhat higher levels of diazotizable substances in the urine than healthy controls and the contributory ratio of the exposed ANA sub...
