CLINICAL RESEARCH STUDY The Clinical Utility of a Positive Antinuclear Antibody Test Result Aryeh M. Abeles, MD, Micha Abeles, MD Division of Rheumatology, University of Connecticut Health Center, Farmington.
The serological diagnosis of juvenile rheumatoid arthritis (JRA) is difficult, with only 7-10% of patients 19S IgM rheumatoid factor positive. About 60-70% of patients are positive for hidden 19S IgM rheumatoid factor, but this test requires serum separation and is not available in most laboratories. Antiperinuclear factor has been described in both seropositive and seronegative adult patients with rheumatoid arthritis, but has not been thoroughly evaluated in children with JRA. This study determined the diagnostic sensitivity and specificity of antiperinuclear factor in patients with JRA. Serum samples from 64 children with JRA, 24 with systemic lupus erythematosus (SLE), and 24 control subjects were tested for the presence of antiperinuclear factor. A total of 10 (83%) of seropositive, polyarticular onset and six (37%) of seronegative, polyarticular onset patients with JRA were positive for antiperinuclear factor. The occurrence of antiperinuclear factor in five (19%) with pauciarticular onset ...

The antinuclear antibody (ANA) test is widely used as a serological marker of autoimmune disease. Antinuclear antibodies are immunoglobulins or antibodies that bind to one or more antigens expressed within the nucleus of human cells. Used selectively, the ANA test can be a useful laboratory tool to help confirm or exclude the diagnosis of systemic rheumatic disease. However, the relatively high prevalence of ANAs in other inflammatory conditions, as well as healthy individuals, can make a positive result difficult to interpret.
Fluorescent antinuclear antibody (ANA) testing was performed on 141 sera from 114 patients with well defined rheumatic diseases including fibrositis syndrome and 24 sera from 24 healthy subjects using HEp-2 cells and rat liver as substrates. ANA titers were almost always higher on HEp-2, in most cas …
The ANA test has a specificity of around 95 percent, meaning that of 20 people who test negative, 19 actually do not have lupus, but one has tested falsely negative and may have lupus. Its sensitivity is even less, meaning that more than one person out of 20 will test falsely positive but will not have lupus. False positive ANAs are fairly common and occur more frequently in older people, people with other autoimmune diseases, with viral infections, some chronic inflammations, and after taking some medications. Medications notorious for producing positive ANA tests are procainamide, used for some heart arrhythmias, and hydralazine, which used to be frequently prescribed to treat high blood pressure. Positive ANAs may persist for years after someone has taken these drugs.. The other common belief which I want to debunk here is that it is always important, even critical, to treat a disease early in the hopes of producing a cure. This belief probably stems from the emphasis we place on detecting ...
Hi I had a positive antinuclear antibody test that came back positive with 160 homogeneous when it is supposed to be at 40 I dont know my doctor has tested me for viral infections which came back negative what is clear to the doctor is that something is fighting me in my body attacking my joints Im going to a rhemuatologist but I dont know what to expect they will test me for lupus and so forth but the doctor doesnt think that is it and tested negative for rhuematoid arthiritis but I have some type of arthiris now from whatever has been attacking the funny thing is that I had some serious injuries bout three months I think knee and feet and fingers knuckles now since about a month ago they seem to be inflammatory not all at once though so far swelling is down on my knees but its not in my fingers and hand has anyone had these symptoms the only family history I have with diseases is leukemia which took my mums brother at an early age and Alzheimers on my dads side no arthiritic conditions ...
Objective: An Italian multicentre study was promoted in order to assess the accuracy of four anti-double-stranded DNA (dsDNA) antibody assays for SLE diagnosis and monitoring. Methods: Two hundred and twenty-three patients with established SLE according to ACR classification criteria were enrolled from 9 centres. They included 59 patients at first evaluation (disease duration ,12 months) and 164 with longer disease duration (median disease duration 120 months). The sera from 55 healthy subjects and 161 patients with rheumatic, infectious or neoplastic diseases were tested as controls. SLE activity was measured by ECLAM score. Anti-dsDNA antibodies were detected in serum by means of FarrzymeTM assay, fluoroenzymeimmunoassay (EliATM), Crithidia luciliae indirect immunofluorescence (CLIFT) or Farr radioimmunoassay (Farr). Cut-off values of quantitative assays were chosen by ROC curves analysis. Statistics were conducted by SPSS software package. Results: Sensitivity for SLE diagnosis ranged between ...
An ANA test detects antinuclear antibodies in your blood. Your immune system normally makes antibodies to help you fight infection. In contrast, antinuclear antibodies often attack your bodys own tissues - specifically targeting each cells nucleus.
To investigate the possible role of anti-ENA autoantibodies in the pathogenesis of SLE nephropathy, we performed a cross sectional clustering study of 91 SLE patients using 75 clinical and laboratory variables examining the presence of anti-dsDNA and ENA autontibodies by ELISA and Western blot. We applied principal component, hierarchical cluster, multiple correspondence and logistical regression analysis. Two polar forms of SLE nephropathy and five clinical groups were identified: group 1 without overt nephropathy (n = 37), group 2 with nephropathy and only proteinuria (n = 19), group 3 nephropathy and only hematuria (n = 11), group 4 with hematuria and proteinuria (n = 14) and group 5 on renal failure (n = 10). When analyzed individually, levels of anti-dsDNA and single anti-ENA antibodies did not allow us to differentiate between renal and non-renal groups. However, when the anti-ENA autoantibodies were analyzed as a cluster, a high predictive value for clinical nephropathy was obtained. ...
The results of antinuclear antibody tests using the indirect immunofluorescence technique may be reported as a description of the pattern and the intensity of fluorescence obtained at a certain dilution. If quantitative results are required titration is necessary. Such titrations may vary greatly between different laboratories. The present study involving 26 laboratories shows an improvement of interlaboratory comparability for the homogeneous fluorescence pattern when a common reference serum is used. Cultured cells as substrate appear to give better quantitative agreement than rat liver sections. National reference sera should be standardised in items of the appropriate WHO reference preparation. ...
Three IgM monoclonal anti-DNA antibodies were produced by hybridoma techniques from an MRL-lpr/lpr mouse using denatured DNA (dDNA) as the selection antigen. All three antibodies also bound poly(dT), poly(rA), and the single-stranded random copolymer poly(dI,dT), and each antibody displayed a unique preference for a limited array of other ribo- and deoxyribopolynucleotides based on direct binding as well as inhibition studies. Inability to identify a common primary structure in the polynucleotides reactive with each antibody suggested that higher ordered structures may be important. This notion was supported by the finding that oligomers of thymidine of 25-30 nucleotides or less were ineffective in blocking antibody binding to dDNA or poly(dT). However, deliberate destabilization of putative secondary structures by decreasing counterion concentration and increasing temperature had little effect on antibody binding to poly(dT). Since the antigenic polynucleotides in general contain little known ...

The immune system makes an abundance of proteins called antibodies. Antibodies are made by white blood cells (B cells). The antibodies recognize and combat infectious organisms (germs) in the body. Antibodies develop in our immune system to help the body fight infectious organisms. When an antibody recognizes the foreign proteins of an infectious organism, it recruits other proteins and cells to fight off the infection. This cascade of attack is called inflammation.. Sometimes these antibodies make a mistake, identifying normal, naturally-occurring proteins in our bodies as being "foreign" and dangerous. When these antibodies make incorrect calls, identifying a naturally-occurring protein (or self protein) as foreign, they are called autoantibodies. Autoantibodies start the cascade of inflammation, causing the body to attack itself. The antibodies that target "normal" proteins within the nucleus of a cell are called antinuclear antibodies (ANA). Most of us have autoantibodies, but typically in ...

BACKGROUND: Morphea is an inflammatory autoimmune skin sclerosis of unknownetiology. A causative role of Borrelia burgdorferi infection has beencontroversially discussed, but no conclusive solution has yet been achieved. OBJECTIVE: Intrigued by 3 young patients with severe Borrelia-associated morpheaand high-titer antinuclear antibodies, we retrospectively examined therelationship between Borrelia exposure, serologic autoimmune phenomena and ageat disease onset in morphea patients. METHODS: In 90 morphea patients thepresence of Borrelia-specific serum antibodies was correlated to the age atdisease onset and the presence and titers of antinuclear antibodies. Patientswith active Borrelia infection or high-titer antinuclear antibodies due tosystemic sclerosis or lupus erythematosus served as controls. RESULTS: We observed a statistically highly significant association between morphea, serologic evidence of Borrelia infection, and high-titer antinuclear antibodies when disease onset was in childhood ...

The ANA test is ordered when someone shows signs and symptoms that are associated with a systemic autoimmune disorder. People with autoimmune disorders can have a variety of symptoms that are vague and non-specific and that change over time, progressively worsen.The antinuclear antibody (ANA) test is used as a primary test to help evaluate a person for autoimmune disorders that affect many tissues and organs throughout the body (systemic) and is most often used as one of the tests to help diagnose systemic lupus erythematosus (SLE). ANA are a group of autoantibodies produced by a persons immune system when it fails to adequately distinguish between "self" and "nonself." They target substances found in the nucleus of a cell and cause organ and tissue damage. Depending on a persons signs and symptoms and the suspected disorder, ANA testing may be used along with or followed by other autoantibody tests. ...

Any antibody to nuclear components is an ANA. Most patients with ANAs do not have SLE, but most people with SLE have ANAs. The most common screening test is IIF on rodent liver or human epithelial (HEp2) tissue,3 although ELISA tests are available.4,5 Lupus erythematous cells simply represent nuclei opsonised by ANAs and are no longer used in diagnosis. Although ANAs are very sensitive for SLE, positive ANAs are common, especially in unwell elderly individuals.6-8 Therefore, ANAs have low PPV for SLE in unselected populations or when present in low titres,6,9 and are not diagnostic. One in three healthy people have detectable ANAs on HEp-2 cells at a screening dilution of 1/40 and one in 20 will be positive at 1/160. HEp-2 cells produce more positive ANAs than rat tissue, and some ANAs (for example, anticentromere antibodies) can only be reliably detected on HEp-2 substrate. Although "ANA negative" SLE is reported,10 it is not clear whether this is the result of a technical artifact or whether a ...

This test guide provides information about tests that may be useful for the diagnosis of autoimmune diseases. Three screening approaches that use antinuclear antibody and specific antibody tests are discussed.
The immunofluorescent antinuclear antibody (ANA or FANA) test is positive in almost all individuals with systemic lupus (97 percent), and is the most sensitive diagnostic test currently available for confirming the diagnosis of systemic lupus when accompanied by typical clinical findings. When three or more typical clinical features are present, such as skin, joint, kidney, pleural, pericardial, hematological, or central nervous system findings as described above, a positive ANA test confirms the diagnosis of systemic lupus ...
It is our premise that JDMS is a distinct disease entity and that the increase in HLA-B8 and -DR3 in JDMS places this disease in the company of other immunopathic disorders. There are conflicting data concerning immunological abnormalities in JDMS , but there appears to be impairment of natural killing and evidence of complement activation. The frequent positive ANA in JDMS raises the speculation of its relationship to the antinuclear antibody, Jo-1, found in some adults with PM, which has specificity for tRNAHis. Most newly diagnosed JDMS patients have antibodies to Coxsackie B which may be related to the pathogenesis of this disease. Specific pathological findings of endothelial cells containing reticulotubular inclusions are associated with vessel occlusion, subsequent obliteration and increased Factor VIII levels in clinically active disease ...

ANA also goes up and down all the time. The info and advice in the above posts is excellent. And the funny thing is that I can feel like crap and my ANA will be relatively low, then feel great and its high. So go figure. I hope thatyour other test are normal and that its just the way you are and not any illness. My ANA was elevated for over a decade and probably longer with no symptoms, then I developed diabetes with NASH and endocrine problems and all of that was still unrelated to my ANA according to my docs. then I developed sjogrens syndrome, a relatively mild form of autoimmune disease. I believe the interferon I took caused my autoimmune disease to become active. I think otherwise I would have continued to havean elevated ANA with no symptoms for the rest ofmy life otherwards ...
The production of auto-antibodies is one of the predominant characteristics of autoimmune disorders. Because IL-2 deficient mice develop autoimmunity, we asked how IL-2 deficiency might impair endogenous mechanisms of B cell tolerance. To this end, we mated BALB/c anti-dsDNA H chain knock-in mice, in which B cells producing anti-dsDNA antibodies are properly regulated, with IL-2 deficient mice and assessed the phenotype of their offspring. IL-2 deficient mice expressing the anti-dsDNA H chain knock-in allele developed anti-dsDNA antibodies of both IgM and IgG isotypes. Production of these antibodies occurred through the disruption of several mechanisms of endogenous tolerance, including deletion, maturational arrest, and follicular exclusion. In summary, our results suggest that IL-2 plays an important role in regulating B cell tolerance.
After washing to remove non-specifically bound antibodies, the substrate is incubated with an anti-human antibody conjugated to fluorescein. When results are positive, a stable three-part complex forms, consisting of fluorescent antibody bound to human antinuclear antibody that is bound to nuclear antigen. This complex can be visualized with the aid of a fluorescent microscope. In positive samples, the cell nuclei will show a bright apple-green fluorescence with a staining pattern characteristic of the particular nuclear antigen distribution within the cells. If the sample is negative for ANA, the nucleus will show no clearly discernible pattern of nuclear fluorescence. The cytoplasm may demonstrate weak staining while the non-chromosome region of mitotic cells demonstrates brighter staining ...

Hi, my name is Kristi. I was just diagnosis with CREST. My sister has LUPUS (involving kidneys) and after participating in a LUPUS genetic study for her, they found a high positive ANA in me. I went to my general practitioner and they did another ANA and it was negative. I went to a Rheumatologist and she told me they have to specifically ask for the anticentromere pattern of ANA or they will not test for this rare pattern and that is why I got the negative result the second time. The rheumatologist repeated the ANA once more on me, specifically asking for the centromere pattern and it came back with a high positive of 1:1,280. She diagnosed me with CREST due to my raynauds and daily severe heart burn. I also have the beginning skin changes on my fingers. She ordered the lung PFT, Echocardiogram heart test and a Barrium swallow to check the condition of my esophagus. She thinks it is limited, not diffuse, so I guess I am lucky there. Any advice or encouragement is welcome. Thanks, Kristi ...
