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.
Introduction The finding of antinuclear antibody (ANA) positivity in a wholesome individual is usually of unknown significance and generally is benign. Outcomes Overall, ANA amounts are considerably higher in females than in men which association retains in patients using the autoimmune illnesses lupus and arthritis rheumatoid (RA) aswell as in healthful controls (HC). Age group was not considerably connected with ANA amounts and the raised ANA values cannot be described by higher IgG amounts. Another autoantibody, anti- cyclic citrullinated peptide (CCP), didnt present gender dimorphism in arthritis rheumatoid (RA) or healthful people. The autoantigen array demonstrated significant elevations of various other autoantibodies in high ANA HCs. A few of these autoantibodies had been aimed to antigens in others and epidermis had been linked to autoimmune circumstances of kidney, joints or thyroid. Gene appearance analyses showed a larger prevalence of considerably upregulated genes in HCs with ...
TY - JOUR. T1 - Antinuclear antibodies. T2 - Clinical applications. AU - Wanchu, A.. PY - 2000/12/1. Y1 - 2000/12/1. N2 - One of the common serological hallmarks of autoimmune disorders is the presence of various autoantibodies in the sera of patients affected by these disorders. Antinuclear antibodies (ANA) detection is often needed to aid the diagnosis in several autoimmune disorders. In view of the different methodologies available for their detection, it becomes essential to understand the advantages and pitfalls of each procedure. This brief review discusses some methodological aspects of ANA detection and the clinical relevance of the presence of some of the autoantibodies found in the sera of patients with autoimmune disorders..

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 ...

An ENA (Extractable Nuclear Antigen Antibodies) panel detects the presence of one or more specific autoantibodies in the blood. Autoantibodies are produced when a persons immune system mistakenly targets and attacks the bodys own tissues. This attack can cause inflammation, tissue damage, and other signs and symptoms that are associated with an autoimmune disorder.. ENA are a subset of antinuclear antibodies (ANA), antibodies directed against proteins found in the nucleus of cells. Certain autoimmune disorders are characteristically associated with the presence of one or more extractable nuclear antigen antibodies. This association can be used to help diagnose an autoimmune disorder and to distinguish between disorders.. The ENA panel is typically a group of 6-10 autoantibody tests. The number of tests offered will depend on the laboratory and the needs of the doctors and patients it serves. ENA panel tests, and other less common ENA tests, may be able to be ordered separately depending on the ...
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 ...

A short alternative open reading frame named ORF7a has recently been discovered within the nucleocapsid gene of the porcine reproductive and respiratory syndrome virus (PRRSV) genome. Proteins (7ap) translated from the ORF7a of two divergent strains - a type I and a type II - are able to completely reduce the motility of nucleic acids at relatively high molar charge ratios in gel retardation assays indicating strong dsDNA- and ssRNA-binding capability. Conserved RNA- and DNA-binding properties suggest that nucleic acid binding is a functional property of the divergent 7aps, and not an arbitrary consequence of their net positive charge. Sera from Hu7ap-immunised pigs and mice did not react with Hu7ap or Hu7ap-GFP; however, antinuclear antibodies were detected in the sera of the immunised animals, suggesting an ability of Hu7ap to interact with or mimic autoantigenic macromolecules. ...
When purified under rigorous conditions, some murine anti-double-stranded-DNA (anti-dsDNA) antibodies actually bind chromatin rather than dsDNA. This suggests that they may actually be antinucleosome antibodies that only appear to bind dsDNA when they are incompletely dissociated from nucleosomes. Experiments in murine models suggest that antibody-nucleosome complexes may play a crucial role in the pathogenesis of glomerulonephritis in systemic lupus erythematosus. Some human monoclonal anti-DNA antibodies are pathogenic when administered to mice with severe combined immunodeficiency (SCID). Our objective was to achieve stable expression of sequence-altered variants of one such antibody, B3, in Chinese hamster ovary (CHO) cells. Purified antibodies secreted by these cells were tested to investigate whether B3 is actually an antinucleosome antibody. The pathogenic effects of the antibodies were tested by implanting CHO cells secreting them into SCID mice. Purified B3 does not bind to dsDNA unless

Y1 - 1996/2/6. N2 - Understanding the molecular basis of DNA recognition by anti-DNA autoantibodies is a key element in defining the role of antibody·DNA complexes in the pathogenesis of the autoimmune disorder systemic lupus erythematosus. As part of our efforts to relate anti-DNA affinity and specificity to antibody structure, and ultimately to disease pathogenesis, we have generated a panel of eight anti-DNA mAbs from an autoimmune MRL MpJ- lpr/lpr mouse and have assessed the binding properties of these antibodies. We find that none of our anti-DNA mAbs bind to RNA and only one low-affinity mAb cross-reacts with non-DNA antigens, albeit weakly. None of the mAbs in our panel bind double-stranded DNA exclusively. Antibodies that recognize single-stranded DNA can be categorized into two groups based on ...
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 ...

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 ...
The medical institutes who establish diagnostic standards say that, you probably have Lupus if you have two or more of these symptoms plus a positive ANA (antinuclear antibodies) blood test, OR if you have four or more of these symptoms with no other reason for them ...
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 ...
SUMMARY. Twenty patients with unexplained pulmonary fibrosis and circulating antinuclear factor were identified. Diseases commonly associated with antinuclear factor, such as systemic lupus erythematosus or scleroderma, were excluded. Half of the patients showed typical restrictive ventilatory defects and X-ray evidence of severe fibrotic changes. The remaining patients predominantly had evidence of obstructive airway diseases.. Four lung biopsies were available. Three showed histological evidence of interstitial pulmonary fibrosis. Immunofluorescent study of one of the biopsy sections with pulmonary fibrosis from a patient with only IgM serum antinuclear factor showed IgM in the alveolar septa. Relatively little fibrosis was present in immunoglobulin-laden areas whereas no immunoglobulin could be demonstrated in the adjacent alveolar septa showing marked fibrosis. Seven out of 10 patients with X-ray evidence of severe interstitial pulmonary fibrosis and typical restrictive ventilatory defects ...
Objective: To investigate the rote of anti-nucleosome antibodies (AnuA) in systemic lupus erythematosus (SLE).. Methods: IgG anti-nucleosome antibodies were detected by enzyme-linked immunosorbent assay (ELISA) in the sera of 233 SLE and 220 other rheumatic diseases′ patients as well as 31 health controls. The patients were also evaluated for clinical and biological parameters.. Results: (1) Out of 233 SLE patients, 144 (61.8%) were seropositive for AnuA, which was significantly higher than that of patients with other rheumatic diseases [2.7% (6/220), P < 0.001]; the sensitivities and specificities of AnuA in SLE were 61.8% and 97.6%, respectively. (2) The positive rated of AnuA in SLE lacking of anti-DNP, anti-cmDNA, anti-Sm and anti-dsDNA antibodies were 57.1%, 55.9%, 62.4% and 51.2%, respectively. (3) The frequency of the fever, skin rash, and arthralgia were significantly higher in 144 positive AnuA SLE than those in AnuA negative SLE (P < 0.05). The frequency of leukopenia, elevations of ...
Clinical trial for SYSTEMIC LUPUS ERYTHEMATOSUS , Study of the Safety and Efficacy of GDC-0853 in Participants With Moderate to Severe Active Systemic Lupus Erythematosus
NLRP3 inflammasome has been implicated in the pathogenesis of systemic lupus erythematosus (SLE). The activation of NLRP3 inflammasome results in the production of IL-1β and the subsequent inflammation. Anti-dsDNA antibodies (anti-dsDNA Abs) play critical roles in the development and progression of SLE. However, the mechanism of NLRP3 inflammasome activation in SLE is still not known. This study investigated the activation of NLRP3 inflammasome stimulated by anti-dsDNA Abs in monocytes/macrophages from SLE patients. Monocytes/macrophages from SLE patients or healthy controls were stimulated with anti-dsDNA Ab-positive serum or purified anti-dsDNA Abs. Activation of inflammasome was measured by flow cytometry or Western blot. Anti-dsDNA Abs isolated from active SLE patients were injected into female (NZB × NZW) F1 mice and the activation of NLRP3 inflammasome and the frequencies of Th17 and Treg were examined. The activity of caspase-1 was significantly increased in active SLE patients and was

Skin testing can confirm many common types of allergies. Among the most helpful are the anti-Sm and anti-ds-DNA, because when positive, they strongly suggest SLE. I was told I had Lupus because of a positive ANA. Symptoms of ANA-positive rheumatic diseases are listed in TABLE 1. Read on to learn more about each type. 0 comment . Intradermal Skin Test . Typically, if a person tests positive for the antinuclear antibody, it means only that the person could have lupus. Your immune system normally makes antibodies to help you fight infection. In intradermal (under the skin) testing, the doctor or nurse injects a tiny amount of allergen into the outer layer of skin.

Abstract OBJECTIVE/HYPOTHESIS: The aim of this prospective study is to evaluate the possible association between Ménières disease (MD) and autoantibodies. METHODS: Fifty-five patients with definite MD (51 unilateral and 4 bilateral) were matched with 55 patients with unilateral vestibular paresis without cochlear involvement and 55 healthy subjects. Blood samples were collected from all study subjects for the determination of serum TSH, free triiodothyronine, free thyroxine, anti-TSH receptor antibody, antithyroperoxidase antibody, antithyroglobulin antibody and of antibodies to non-organ-specific antigens, namely antinuclear antibodies, antibodies to extractable nuclear antigens and antineutrophilic cytoplasmic antibodies. RESULTS: Thirty-three subjects (60%) of the MD group had 1 or more elevated serum autoantibody levels, both organ and non-organ specific; 16 patients (29.1%) with unilateral vestibular paresis had 1 or more elevated serum autoantibody levels, while 13 healthy subjects ...
Objective: Rheumatic diseases with involvement of the central nervous system (RDwCNS) may mimic multiple sclerosis (MS). Inversely, up to 60% of MS-patients have antinuclear autoantibodies (ANAs) and may be misdiagnosed as RDwCNS. The detection of antibodies against extractable nuclear antigens (ENA) and oligoclonal bands (OCB) are established valuable diagnostic tools in the differential diagnosis of RDwCNS and MS. The MRZ-reaction (MRZR) is defined by three antibody indices (AIs) against neurotropic viruses and is frequently positive in MS. To investigate the added value of MRZR combined with testing for antibodies against ENAs and OCB detection to distinguish RDwCNS from ANA positive MS ...

Forty-five fetuses with CHB were evaluated by analysis of anti-Ro/La antibodies using sensitive laboratory methods. Results. There were 9 cases of anti-Ro/La-negative CHB; 3 died (33.3%). Only 3 (33.3%) were complete in utero and 5 (55.5%) were unstable. No specific etiology was diagnosed. Six infants (66.6%) were given pacemakers. There were 36 cases of anti-Ro/La-positive CHB. All except 2 infants (94.4%) had complete atrioventricular block in utero. Ten ...
Nearly 75% of patients receiving procainamide therapy will develop a positive ANA test within the first year of treatment, and over 90% develop a positive ANA
A progressively wide range of studies exist into the association of Anti-Nuclear Antibodies (ANAs) with Autoimmune Rheumatic Diseases (ARDS), such as Systemic Lupus Erythematosus (SLE), Sjogrens Syndrome (SjS), Systemic Scleroderma (SS), Rheumatoid Arthritis (RA), Reynauds phenomena (RP) to name but a few of the more serious and debilitating ARDs1-4. It is thought that a single base mutation in the gene responsible for anti-Phosphotidylcholine (aPTC), (an IgM Natural Autoantibody (NAb) responsible for clearance of cellular debris) is a likely mechanism by which ANA pathogenesis may originate5. Visualization of these antibodies through Indirect Immuno-Fluorescence (IIF) has long remained the principle detection path, the Gold Standard. The objective of this study is to investigate the replacement of IIF with ELISA as a screening/diagnostic method in the ongoing effort to eliminate the time-consuming and subjective nature of IIF; ELISA being easily adapted to automation. 350 routine anonymised ...
TY - JOUR. T1 - Hydronephrosis associated with antiurothelial and antinuclear autoantibodies in BALB/c-Fcgr2b-/-Pdcd1-/- mice. AU - Okazaki, Taku. AU - Otaka, Yumi. AU - Wang, Jian. AU - Hiai, Hiroshi. AU - Takai, Toshiyuki. AU - Ravetch, Jeffrey V.. AU - Honjo, Tasuku. PY - 2005/12/19. Y1 - 2005/12/19. N2 - Because most autoimmune diseases are polygenic, analysis of the synergistic involvement of various immune regulators is essential for a complete understanding of the molecular pathology of these diseases. We report the regulation of autoimmune diseases by epistatic effects of two immunoinhibitory receptors, low affinity type IIb Fc receptor for IgG (FcγRIIB) and programmed cell death 1 (PD-1). Approximately one third of the BALB/c-Fcgr2b-/-Pdcd1-/- mice developed autoimmune hydronephrosis, which is not observed in either BALB/c-Fcgr2b-/- or BALB/c-Pdcd1-/- mice. Hydronephrotic mice produced autoantibodies (autoAbs) against urothelial antigens, including uroplakin IIIa, and these antibodies ...
Prolactin is a peptide hormone produced by the anterior pituitary gland that is critical in lactation. Prolactin can also be produced by lymphocytes, and both B and T cells express prolactin receptors. These findings have suggested that prolactin has immunomodulatory functions. Studies in spontaneously autoimmune hosts have demonstrated a role for prolactin in augmenting autoreactivity. We chose to analyze prolactin effects on anti-DNA B cells in nonspontaneously autoimmune female BALB/c mice transgenic for the heavy chain of an anti-DNA antibody. Treatment with prolactin for 4 weeks induced a lupus-like phenotype with an increased number of transgene-expressing B cells, elevated serum anti-DNA antibody titers, and glomerular immunoglobulin deposits. Prolactin caused a decrease in the population of transitional B cells and an increase in mature follicular and marginal zone B cells. The DNA-reactive B cells had a follicular cell phenotype. Anti-DNA hybridomas demonstrated that prolactin alters ...

Objective. To analyze the clinical value of anti-DFS70 antibodies in a cohort of patients undergoing routine antinuclear antibodies (ANAs) testing. Methods. Sera with a dense fine speckled (DFS) indirect immunofluorescence (IIF) pattern from 100 consecutive patients and 100 patients with other IIF patterns were tested for anti-DFS70 antibodies by a novel chemiluminescence immunoassay (CIA) and for ANA by ANA Screen ELISA (both INOVA). Results. Among the 100 patients with a DFS IIF pattern, 91% were anti-DFS70 positive by CIA compared to 3% in the comparator group . The CIA and IIF titers of anti-DFS antibodies were highly correlated (rho = 0.89). ANA by ELISA was positive in 35% of patients with the DFS IIF pattern as compared to 67% of patients with other patterns . Only 12.0% of patients with DFS pattern and 13.4% with DFS pattern and anti-DFS70 antibodies detected by CIA had systemic autoimmune rheumatic disease (SARD). Only 5/91 (5.5%) patients with anti-DFS70 antibodies had SARD and their sera
LU, Zhimin et al. Altered peripheral lymphocyte subsets in untreated systemic lupus erythematosus patients with infections. Braz J Med Biol Res [online]. 2019, vol.52, n.4, e8131. Epub 15-Abr-2019. ISSN 1414-431X. https://doi.org/10.1590/1414-431x20198131.. The leading cause of death in systemic lupus erythematosus (SLE) patients is infection. The objective of this study was to evaluate the distribution of lymphocyte subsets in untreated SLE patients with infections. This was a cross-sectional study. Data from January 2017 to May 2018 were collected. Flow cytometry was used to measure the peripheral lymphocyte subsets including CD3+T cells, CD4+T cells, CD8+T cells, CD19+B cells, CD3-CD16+CD56NK cells, and CD3+CD16+CD56NKT cells in 25 healthy controls and 52 treatment-naive SLE patients, among whom 13 were complicated with infections. Association between the lymphocyte subsets and infections was further analyzed. SLE patients with infections (n=13) showed a significantly higher incidence rate of ...
Group A only: patients on immunosuppressive treatments had them withdrawn at baseline. All patients were allowed up to 160 mg depomedrol at baseline which could be repeated within two weeks up to a total of 4 shots maximum or until satisfactory improvement. Time to flare was calculated from baseline. moderate disease at baseline was defined as up to 3 BILAG B (moderate disease) organ scores, no BILAG A (severe disease) score and a SLEDAI ,/= 10. Severe disease required ,3 BILAG B, OR at least one BILAG A OR SLEDAI , 10 or meeting criteria for a severe flare on the SELENA SLEDAI flare index. At baseline 25 patients with moderate disease. 16 patients had severe disease. Note: severe rash with A on BILAG is only SLEDAI=2, explaining some discrepancies in measures ...
The antinuclear antibodies (ANA) test has been a cornerstone of the evaluation of connective tissue disease. The aim of this study was to investigate the diagnostic value of the ANA test in pleural or pericardial effusions of unknown causes. Over a 3-yr period, a total of 126 pleural fluid and 30 pericardial fluid samples were analysed. ANA tests were performed using a commercially available kit. The ANA kit used an indirect immunofluorescent antibody method with a human epithelial (HEP-2) cell line as substrate. Patients with high fluid ANA titre (,1:160) received a second aspiration 2 weeks after the initial aspiration if diagnosis was not confirmed. ANA results were positive in 39 pleural and 10 pericardial fluid samples. All but one of the effusions with positive ANA testing were exudative. Eleven pleural or pericardial effusions due to active systematic lupus erythematosus were identified and all had high ANA titres (1:160) with various staining patterns. Thirty-eight of 145 patients (26%) ...

AU - Harley, J. B.. AU - James, J. A.. AU - Fischbach, M.. AU - Sanz, I.. PY - 2000/12/15. Y1 - 2000/12/15. N2 - The anti-Smith (Sm) autoantibody response is highly specific for systemic lupus erythematosus and is predominantly targeted to the Sm-B/B and -D1 polypeptides. In all animal species thus far studied, anti-Sm Abs initially recognize proline-rich epitopes in the carboxyl terminus of the Sm-B/B protein and subsequently to multiple other epitopes in B/B and D. The absence of appropriate mAbs has limited our understanding of the genetic and structural basis of this autoimmune response. Using phage-display technology and lymphocytes from a systemic lupus erythematosus patient we have generated the first and only panel of human IgG anti-Sm mAbs thus far available. These Abs reproduced to a ...

N2 - When monoclonal ANAs and non-ANAs generated from a genetically simplified mouse model of lupus, B6.Sle1, were recently compared, the ANAs exhibited three sequence motifs in their immunoglobulin heavy chains, including increased cationicity in CDR3 (motif A), reduced anionicity in CDR2 (motif B) and increased aspartate at H50 (motif C). The present study was designed to elucidate the extent to which these ANA-associated sequence motifs might be hard-wired into the primary B-cell repertoire in lupus. The immunoglobulin heavy chain sequence of total splenic B-cells, follicular B-cells and marginal zone B-cells from B6.Sle1 congenic mice and ...
OBJECTIVE: To compare the clinical, laboratory, and demographic variables of women in our clinic with systemic lupus erythematosus (SLE) who have had a pregnancy resulting in a live birth and identify any correlations with either term or preterm delivery. METHODS: Pregnancies in women with SLE from 1999 to 2001 were retrospectively reviewed. We recorded demographic data, disease activity (SLE Disease Activity Index, SLEDAI), obstetric history, prednisone dosage, other medications taken during pregnancy, history of renal disease, and autoantibody status [including antinuclear antibody, anti-DNA, anticardiolipin IgG (aCL), and lupus anticoagulant (LAC)]. Preterm delivery was defined as gestational age at delivery , 37 weeks. We performed a literature survey using PubMed and the key words SLE, pregnancy, and outcome. RESULTS: Of the 72 pregnancies, 28 (38.9%) resulted in preterm deliveries. There were no significant differences in any demographic or disease variables measured comparing term versus ...
Congenital heart block (CHB) is associated with maternal antibodies to Ro (SSA) and La (SSB) that cross the placenta and damage the AV node of fetus. An asymptomatic 27-year-old primigravida, diagnosed with second degree fetal heart block was investigated and found positive for antinuclear antibodies (ANA), anti-Ro and anti-La antibodies. Fetal echocardiography (2D-echo) showed no structural defect but bradycardia. The patient was started on dexamethasone 8mg/day. She had preterm premature rupture of membranes (PPROM) at 34 weeks and underwent emergency cesarean section (LSCS). The baby was born with complete heart block but was managed conservatively in view of low birth weight. The infant is now 5 months old and permanent pacemaker implantation is planned. ...
Patients with drug-related lupus erythematosus produce antibodies to nuclear histones which can be detected by a three-step indirect immunofluorescence technique. Procainamide-related antinuclear antibodies were detected by this technique, but hydralazine-related antinuclear antibodies were not. Certain evidence suggests that antibodies induced by the two drugs are reactive with different subclasses of histones. Hydralazine was shown to interact with a soluble DNA-histone complex, and the resulting interaction rendered the histone moiety resistant to trypsin digestion. This mechanism may help to maintain DNA-histone complexes in a potentially immunogenic form and result in the production of autoantibodies ...

Discussion. The focus of care is to reduce the inflammatory effect of the cervical capsules or facetal region, which may traction the adjacent spinal nerve roots and centralize the diffuse pain picture. Emphasis on patient education is required. The postural changes we see may be of a cumulative nature and contribute to mid-back pain as a tendonosis strain and ligamentous sprain, also due to her tiny size in repeated lifting attempts. Synovitis of a rheumatoid arthritic nature, or member of an inflammatory arthopathy family, is strongly suspected. Additionally, if the antinuclear antibody titer is high, systemic lupus is suspected. If she develops dry mouth, dry eye, dry cough or sicca syndrome, present with a rheumatism, SLE or connective-tissue disease, we may have an overlap in conditions. Similarly, myositis is frequently a part of inflammatory arthopathies. Thus, my clinical differential diagnosis would be a form of rheumatoid arthrosis. A patient such as this should acquire baseline ...
OBJECTIVE: To determine the frequency of prolonged remission in systemic lupus erythematosus (SLE) using strict criteria for remission and to define disease characteristics and prognosis of patients achieving this state. To also determine the frequency of remission utilizing less restrictive definitions, such as allowing shorter period of disease quiescence, persistence of serological activity, or treatment in the absence of clinical disease. METHODS: Patients registered in the Lupus Clinic database between 1970 and 1997 with visits no more than 18 months apart were identified. Prolonged remission was defined as a 5-year consecutive period of no disease activity (SLE disease activity index, SLEDAI = 0) and without treatment (corticosteroids, antimalarials, or immunosuppressants). Prolonged serologically active, clinically quiescent (SACQ) was defined as active serology (elevated anti-dsDNA by Farr assay or hypocomplementemia) but no clinical activity on SLEDAI and no treatment. RESULTS: Seven ...

Objective(s): Apoptosis is a tightly regulated process and plays a crucial role in autoimmune diseases. Because abnormalities in apoptosis are considered to be involved in the pathogenesis of systemic lupus erythematosus (SLE), in present study we studied the apoptosis in T lymphocytes from Iranian SLE patientsat protein and gene expression levels for some molecules which are involved in apoptosis pathways. Materials and Methods: Thirty five SLE patients (23 female, 12 male), and 20 age matched controls (10 female, 10 male) participated in this study. T lymphocytes were isolated from peripheral blood mononuclear cells (PBMCs) using MACS method. Apoptosis rate was studied at protein level by flow cytometer using Annexin V, and at gene expression level using semi-quantitative RT-PCR method for detection of Fas, FasL, Bcl-2, caspase 8, and caspase 9 genes. Results: The percentage of apoptotic cells in SLE patients was not different in comparison with controls (20.2% ± 1.4 vs 21.1% ± 1.0), but the

Hi everyone. I am new here (and newly diagnosed) but wanted to share a little about myself. A year ago I had lumps on my neck, which after biopsy were thought to be a form of cutaneous lupus. My general practitioner ran a series of blood tests and my ANA was 1:640 anti-centromere. I went to a rheumatologist 2 weeks later who reran the blood work with a specialty lab - ANA was 1:2560. At this point I had no clinical symptoms and she told me it is possible I may never develop any. I had a baseline Echo and continued life as normal. A few weeks ago my life was turned upside-down. I began experiencing excruciating pain in my finger tips on my left hand. It felt like theyd been slammed in a car door and I could not use my hand at all. Went to general practitioner and then ER after 2 of them turned purple and would not change back to red. Both thought possibly Raynauds but it was not a classic presentation. Got in with rheumatologist again who confirmed Raynauds and explained that with scleroderma ...
RESULTS:Mean IgG-anti-IgA levels were significantly higher in psoriasis patients. The frequency of positive ANA testing was 21.1%; however, there was no correlation between IgG-anti-IgA antibody levels and ANA positivity. Only one patient had low IgA levels without high IgG-anti-IgA concentrations ...
Cardiac manifestations of NL include advanced condition defects and occasionally cardiomyopathy with a high morbidity and mortality rate. In this regard, a study by Ismirly et al. (3), which included 325 offspring exposed to maternal anti-SSA/Ro antibodies presenting with NL, showed a case fatality rate of 17%, with one-third of the cases dying in utero and a high post-natal mortality rate, too, because survival at 10 years for children born alive was ,85%, with the majority of deaths occurring within the first year of birth.. In this issue of the Journal, the same team, this time led by Saxena et al. (4), report performing a carefully conducted, complex study presenting the first evidence of maternal passively transferred autoimmunity. Subjects were identified by the U.S. Research Registry for Neonatal Lupus, which enrolled mothers with anti-SSA/Ro and/or SSB/La antibodies and having at least 1 child with NL. Maternal and cord blood in cases with cardiac NL or unaffected pregnancies were ...
A 62 year old woman was referred to hospital by her general practitioner because of a few days history of progressive shortness of breath. She had associated fever but no cough or sputum production. Her medical history included rheumatoid arthritis, for which she had been taking methotrexate for the past 12 years.. On examination, she was visibly dyspnoeic, with low oxygen saturations. Her respiratory rate was 22 breaths/min, oxygen saturation was 90% on air, heart rate was 100 beats/min, blood pressure was 115/72 mm Hg, and her temperature was 37.4ºC. Chronic hand changes, consistent with rheumatoid arthritis, were noted. Bilateral widespread crackles were heard on auscultation of the chest.. Blood tests showed a white blood cell count of 8.8×109/L (reference range 4-10) and a C reactive protein of 1219 nmol/L (,47.6). Further blood tests, including antinuclear antibody (ANA) and extractable nuclear antigen (ENA), were negative. Chest radiography showed diffuse alveolar shadowing throughout ...
