They occur primarily in mitochondrial inner membranes and in bacterial plasma membranes. They are the main antigenic components of the Wassermann-type antigen that is used in nontreponemal SYPHILIS SERODIAGNOSIS.Antiphospholipid Syndrome: The presence of antibodies directed against phospholipids (ANTIBODIES, ANTIPHOSPHOLIPID). The condition is associated with a variety of diseases, notably systemic lupus erythematosus and other connective tissue diseases, thrombopenia, and arterial or venous thromboses. In pregnancy it can cause abortion. Of the phospholipids, the cardiolipins show markedly elevated levels of anticardiolipin antibodies (ANTIBODIES, ANTICARDIOLIPIN). Present also are high levels of lupus anticoagulant (LUPUS COAGULATION INHIBITOR).Lupus Coagulation Inhibitor: An antiphospholipid antibody found in association with systemic lupus erythematosus (LUPUS ERYTHEMATOSUS, SYSTEMIC;), ANTIPHOSPHOLIPID SYNDROME; and in a variety of other diseases as well as in healthy individuals. In vitro, the antibody interferes with the conversion of prothrombin to thrombin and prolongs the partial thromboplastin time.

While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.Glycoproteins: Conjugated protein-carbohydrate compounds including mucins, mucoid, and amyloid glycoproteins.Antibody Formation: The production of ANTIBODIES by proliferating and differentiated B-LYMPHOCYTES under stimulation by ANTIGENS.Antibodies, Neutralizing: Antibodies that reduce or abolish some biological activity of a soluble antigen or infectious agent, usually a virus.Blood Coagulation Factors: Endogenous substances, usually proteins, that are involved in the blood coagulation process.Thrombophilia: A disorder of HEMOSTASIS in which there is a tendency for the occurrence of THROMBOSIS.Immunoglobulin Isotypes: The classes of immunoglobulins found in any species of animal. In man there are nine classes that migrate in five different groups in electrophoresis; they each consist of two light and two heavy protein chains, and each group has distinguishing structural and functional properties.Antibody Affinity: A measure of the binding strength between antibody and a simple hapten or antigen determinant. It depends on the closeness of stereochemical fit between antibody combining sites and antigen determinants, on the size of the area of contact between them, and on the distribution of charged and hydrophobic groups. It includes the concept of "avidity," which refers to the strength of the antigen-antibody bond after formation of reversible complexes.Fluorescent Antibody Technique: Test for tissue antigen using either a direct method, by conjugation of antibody with fluorescent dye (FLUORESCENT ANTIBODY TECHNIQUE, DIRECT) or an indirect method, by formation of antigen-antibody complex which is then labeled with fluorescein-conjugated anti-immunoglobulin antibody (FLUORESCENT ANTIBODY TECHNIQUE, INDIRECT). The tissue is then examined by fluorescence microscopy.Prothrombin: A plasma protein that is the inactive precursor of thrombin.

It is used as a screening test and to monitor HEPARIN therapy.HIV Antibodies: Antibodies reactive with HIV ANTIGENS.Activated Protein C Resistance: A hemostatic disorder characterized by a poor anticoagulant response to activated protein C (APC). The activated form of Factor V (Factor Va) is more slowly degraded by activated protein C. Factor V Leiden mutation (R506Q) is the most common cause of APC resistance.Protein S Deficiency: An autosomal dominant disorder showing decreased levels of plasma protein S antigen or activity, associated with venous thrombosis and pulmonary embolism. PROTEIN S is a vitamin K-dependent plasma protein that inhibits blood clotting by serving as a cofactor for activated PROTEIN C (also a vitamin K-dependent protein), and the clinical manifestations of its deficiency are virtually identical to those of protein C deficiency. Treatment with heparin for acute thrombotic processes is usually followed by maintenance administration of coumarin drugs for the prevention of recurrent thrombosis.

BIRTH of a dead FETUS is STILLBIRTH.Neutralization Tests: The measurement of infection-blocking titer of ANTISERA by testing a series of dilutions for a given virus-antiserum interaction end-point, which is generally the dilution at which tissue cultures inoculated with the serum-virus mixtures demonstrate cytopathology (CPE) or the dilution at which 50% of test animals injected with serum-virus mixtures show infectivity (ID50) or die (LD50).Prednisolone: A glucocorticoid with the general properties of the corticosteroids. It is the drug of choice for all conditions in which routine systemic corticosteroid therapy is indicated, except adrenal deficiency states.Phospholipids: Lipids containing one or more phosphate groups, particularly those derived from either glycerol (phosphoglycerides see GLYCEROPHOSPHOLIPIDS) or sphingosine (SPHINGOLIPIDS).

They are artificial antibodies produced by chemical crosslinking, fusion of HYBRIDOMA cells, or by molecular genetic techniques. They function as the main mediators of targeted cellular cytotoxicity and have been shown to be efficient in the targeting of drugs, toxins, radiolabeled haptens, and effector cells to diseased tissue, primarily tumors.Molecular Sequence Data: Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.Single-Chain Antibodies: A form of antibodies consisting only of the variable regions of the heavy and light chains (FV FRAGMENTS), connected by a small linker peptide. They are less immunogenic than complete immunoglobulin and thus have potential therapeutic use.Antibodies, Blocking: Antibodies that inhibit the reaction between ANTIGEN and other antibodies or sensitized T-LYMPHOCYTES (e.g., antibodies of the IMMUNOGLOBULIN G class that compete with IGE antibodies for antigen, thereby blocking an allergic response). Blocking antibodies that bind tumors and prevent destruction of tumor cells by CYTOTOXIC T-LYMPHOCYTES have also been called enhancing antibodies. (Rosen et al., Dictionary of Immunology, 1989)Factor V: Heat- and storage-labile plasma glycoprotein which accelerates the conversion of prothrombin to thrombin in blood coagulation.

Antibodies against phospholipids and oxidized LDL in alcoholic patients. (1/381)

Antiphospholipid antibodies (APA) are a generic term describing antibodies that recognize various phospholipids. Hepatocyte damage is a cardinal event in the course of alcoholic liver injury and autoantibodies against phospholipids could play an important role in this process. APA in alcoholic patients seem to reflect membrane lesions, impairment of immunological reactivity, liver disease progression and they correlate significantly with disease severity. LDL oxidation is supposed to be one of the most important pathogenic mechanisms of atherosclerosis and antibodies against oxidized low-density lipoprotein (oxLDL) are some kind of an epiphenomenon of this process. The scope of our study was to determine some autoantibodies (IgG-oxLDL and antiphospholipid antibodies) and their possible changes in alcoholic patients. We studied IgG-oxLDL and four APA - anticardiolipin antibodies (ACA), antiphosphatidylserine antibodies (APSA) antiphosphatidylethanolamine antibodies (APE) and antiphosphatidylcholine antibodies (APCA) in 35 alcoholic patients with mildly affected liver function at the beginning of the abuse treatment. The control group consisted of 60 healthy blood donors. In the studied group, we obtained positive results concerning total ACA in 17.1 % of alcoholic patients (8.3 % in the control group), 11.4 % IgG-ACA (6.7 %), 8.6 % IgM-ACA (3.3 %), 14.3 % total APE (6.7 %), 14.3 % total APCA (8.3 %) and 20 % total APSA (8.3 % in the control group). The IgG-oxLDL (406.4+/-52.5 vs 499.9+/-52.5 mU/ml) was not affected in alcoholic patients. We conclude that the autoantibodies against oxLDL are present in sera of alcoholics and healthy blood donors. Based on our results which revealed a wide range of IgG-oxLDL titres in the healthy population, this parameter does not appear to be very promising for the evaluation of the risk of atherosclerosis. Alcoholics with only mild affection of liver functions did not exhibit a significantly higher prevalence of all studied antiphospholipid antibodies (ACA, APSA, APE, APCA) which could lead to membrane lesions in these patients.  (+info)

Cerebral vasculopathy in HIV infection revealed by transcranial Doppler: A pilot study. (2/381)

BACKGROUND AND PURPOSE: There is growing evidence for affection of cerebral vessels during human immunodeficiency virus (HIV) infection. We prospectively evaluated cerebrovascular reserve capacity (CRC) in HIV-seropositive patients by transcranial Doppler sonography (TCD) after systemic administration of acetazolamide. We hypothesized that a disturbed vasoreactivity would reflect the cerebral arteries' involvement in HIV infection. METHODS: We assessed the mean blood flow velocity (BFV) of the middle cerebral artery and its increase after intravenous administration of 1 g acetazolamide (CRC) in 31 HIV-infected individuals without symptoms of cerebrovascular disease (mean+/-SD age, 39+/-11 years). Stenotic or occlusive lesions of the large brain-supplying arteries were excluded by color-coded duplex and transcranial imaging. BFV and CRC were also measured in an age-matched group of 10 healthy control subjects. Patients were classified according to clinical, laboratory, and neurophysiological parameters. We also performed cerebral MRI (n=25) and rheumatological blood tests (n=26). RESULTS: Baseline BFV and CRC both were significantly reduced in HIV-infected patients as compared with control subjects (P<0.05, Student's t test). These findings did not correlate with duration of seropositivity, helper cell count, or other clinical, rheumatological, and neuroradiological findings. CONCLUSIONS: Our findings support the hypothesis of a cerebral vasculopathy etiologically associated with HIV infection.  (+info)

Anti-phospholipid antibodies and CD5+ B cells in HIV infection. (3/381)

This cross-sectional study evaluates the correlation between anti-phospholipid antibodies and CD5+ B cells in 110 patients infected with HIV-1. There were 89.1% of the patients who had IgG antibodies against cardiolipin and phosphatidylserine. The prevalence of IgM and IgA antibodies was < 22%. AIDS was associated with lower frequencies of IgM antibodies against cardiolipin (P = 0.05) and IgG-antibodies against cardiolipin and phosphatidylserine (P = 0.011). Drug users had higher IgM antibodies against phospholipids than patients from other risk groups (P = 0.02). A history of thromboembolic events was not accompanied by higher levels of anti-phospholipid antibodies (P > 0.2). No correlation between anti-phospholipid antibodies and CD5+ B cells was detected. Percentage part of CD5+ B lymphocytes was elevated in all patients and absolute CD4+ T lymphocyte counts and HIV p24 antigen were inversely correlated. In advanced disease a significant reduction of anti-phospholipid antibodies was contrasted with persistent elevation of CD5+ B lymphocytes. These observations may reflect immunological dysfunction involving apoptosis and endothelial damage rather than polyclonal B cell hyperstimulation. A possible explanation would be that in HIV infection an increased rate of spontaneous apoptosis in peripheral blood lymphocytes is accompanied by functional and structural changes of mitochondria. Therefore, structurally altered mitochondrial phospholipids could serve as antigen to induce specific humoral immune responses.  (+info)

Antibodies to adult human endothelial cells cross-react with oxidized low-density lipoprotein and beta 2-glycoprotein I (beta 2-GPI) in systemic lupus erythematosus. (4/381)

Cardiovascular manifestations are common in systemic lupus erythematosus (SLE). Oxidized low-density lipoprotein (oxLDL) is implicated in cardiovascular disease, especially atherosclerosis, and cross-reacts with antibodies to cardiolipin (aCL). beta 2-GPI is a plasma protein participating in the coagulating cascade, and is also cofactor for aCL, and some aCL have been shown to be directed against beta 2-GPI and/or complexes between beta 2-GPI and phospholipids. Lysophosphatidylcholine (LPC) is a phospholipid present both in oxLDL and in damaged endothelium, and we recently showed that LPC is involved in the antigenicity of oxLDL. Antibodies to endothelial cells (aEC) correlate with diseases activity in SLE and vasculitis, and we recently showed that aEC are enhanced in cardiovascular disease such as borderline hypertension and early atherosclerosis. aEC were determined using EC from adult V. Saphena Magna. Antibody levels were determined by ELISA. aEC of IgG type were enhanced in 184 patients with SLE compared with 85 healthy controls. There was a close correlation between aoxLDL, aCL, aLPC, a beta 2-GPI and aEC. Binding of sera to EC was competitively inhibited by beta 2-GPI, LPC and oxLDL. Taken together, the data indicate that EC share antigenic epitopes with beta 2-GPI and with oxLDL, especially LPC. Phospholipids in EC membranes may thus be antigenic epitopes. beta 2-GPI may bind to these phospholipids, and become an autoantigen. LPC is formed by oxidation of phospholipids and/or proinflammatory factors leading to activation of phospholipase A2, and the findings indicate the potential role of both lipid oxidation and phospholipase A2 in SLE.  (+info)

Conformationally altered beta 2-glycoprotein I is the antigen for anti-cardiolipin autoantibodies. (5/381)

Anti-cardiolipin autoantibodies (aCL) induce thrombosis and recurrent fetal death. These antibodies require a 'cofactor', identified as beta 2-glycoprotein I (beta 2-GPI), to bind phospholipids. We show here that aCL can bind beta 2-GPI in the absence of phospholipid. Binding of aCL to beta 2-GPI is dependent upon the beta 2-GPI being immobilized on an appropriate surface including cardiolipin, irradiated polystyrene and nitrocellulose membrane. This effect cannot be explained by increased antigen density of beta 2-GPI immobilized on these surfaces. Rather, conformational changes that occur following the interaction of beta 2-GPI with phospholipid render this protein antigenic to aCL. Liquid-phase beta 2-GPI was not antigenic for aCL. Thus, aCL cannot bind circulating beta 2-GPI. These findings may explain why patients with aCL can remain healthy for many years but then undergo episodes of thrombosis or fetal loss without changes in their circulating aCL profile, as the triggering event for these pathologies can be predicted to be one that renders beta 2-GPI antigenic for aCL.  (+info)

A prospective analysis of cognitive function and anticardiolipin antibodies in systemic lupus erythematosus. (6/381)

OBJECTIVE: To prospectively analyze the association between changes in cognitive function and circulating anticardiolipin antibodies (aCL) over a period of 5 years in patients with systemic lupus erythematosus (SLE). METHODS: Cognitive function was assessed in 51 unselected female SLE patients at baseline and after a mean followup of 64.5 months (range 52-71 months), using standardized tests of cognitive function, i.e., the Wechsler Adult Intelligence Scale-Revised, the Wechsler Memory Scale-Revised, and the California Verbal Learning Test. Circulating IgG, IgA, and IgM aCL and anti-double-stranded DNA (anti-dsDNA) antibody levels were determined by enzyme-linked immunosorbent assay on 4-7 occasions over the same time period. Persistent antibody reactivity was defined as levels more than 2 standard deviations (moderately positive) and more than 5 standard deviations (highly positive) above the mean for normal controls over the duration of the study. Changes in overall cognitive performance and in raw scores on individual cognitive tests were compared in patients who were persistently positive or negative for aCL. RESULTS: At baseline 11 patients (22%) were cognitively impaired, compared with 7 (14%) at followup. Between 16% and 37% of patients had persistently elevated aCL levels of different isotypes. There was no significant difference in the prevalence of overall cognitive impairment in patients who were persistently positive for aCL compared with those who were not. In contrast, over the period of study, patients who had persistent IgG aCL positivity had a reduction in psychomotor speed, and patients who had persistent IgA aCL positivity had a reduction in conceptual reasoning and executive ability. Similar associations with anti-dsDNA antibodies were not found. CONCLUSION: These results suggest that IgG and IgA aCL may be responsible for long-term subtle deterioration in cognitive function in patients with SLE.  (+info)

A longitudinal study of anticardiolipin antibody levels and cognitive functioning in systemic lupus erythematosus. (7/381)

OBJECTIVE: To determine the relationship between persistently raised anticardiolipin antibody (aCL) levels and neuropsychological performance in patients with systemic lupus erythematosus (SLE). METHODS: Forty-five patients with SLE underwent a detailed neuropsychological assessment on 2 occasions 12-18 months apart. Serum samples stored since the time of previous assessments as well as samples obtained 6 months to 2 years before the first neuropsychological assessment were tested for IgG aCL levels. Patients were divided into 4 groups according to the number of times their aCL levels were elevated (never, once, twice, 3 times). A wide-ranging battery of new neuropsychological tests was utilized, and the results were compared with double-stranded DNA (dsDNA) antibody levels, C3 levels, and results of magnetic resonance imaging (MRI). RESULTS: Analysis of variance revealed that the group with persistently elevated aCL levels performed less well than the other groups. At the first neuropsychological assessment, poorer performance by this group was noted for letter cancellation (P = 0.02), trail making task B (P = 0.04), and digit span (P = 0.03). At the second assessment, letter cancellation (P = 0.01), trail making task A (P = 0.03), trail making task B (P = 0.01), word fluency (P = 0.01), and reaction time (P = 0.05) were impaired. In contrast, no significant differences in neuropsychological test results were identified with respect to DNA antibody or C3 levels. MRI abnormalities were associated with both persistent elevation of aCL levels and low C3 levels. CONCLUSION: Levels of IgG aCL that were persistently elevated over a 2-3-year period (as opposed to never or occasionally elevated) were associated with significantly poorer performance in cognitive function by patients with SLE. Tasks requiring speed of attention and concentration appear to be particularly affected.  (+info)

A possible role for activated protein C resistance in patients with first and second trimester pregnancy failure. (8/381)

Thrombophilia was recently suggested as a possible factor in recurrent pregnancy losses. We studied prospectively 125 patients (mean age 31.4 +/- 5.6 years) with one or more first or second trimester pregnancy losses for the prevalence of activated protein C resistance (APCR). Proteins C and S antigens, antithrombin III, anticardiolipin, and lupus anti-coagulant were also evaluated. Patients with uterine malformations, hormonal abnormalities, chromosomal translocations and infectious causes were excluded. A control group of 125 women with no past fetal loss were matched with the study group. Whenever the APC-sensitivity ratio (APC-SR) was +info)

Anticardiolipin antibodies purified from serum from patients with systemic lupus erythematosus (SLE) by cardiolipin micelles were studied for their effects on lymphocytes and neutrophils. At a concentration of 160 micrograms/ml they markedly suppressed the [3H]thymidine incorporation of mononuclear cells stimulated by phytohaemagglutinin (4.9 (SEM 1.9%) of the control) and pokeweed mitogen (26.7 (10.5%) of the control). In addition, anticardiolipin antibodies changed the cell cycle of phytohaemagglutinin stimulated lymphocytes such that the S and G2+M phases were significantly diminished (G0/G1 = 64.62%, S = 20.59%, G2+M = 14.78% in the presence of normal human IgG v G0/G1 = 86.07%, S = 10.32%, G2+M = 3.59% in the presence of anticardiolipin antibodies). The suppression of lymphocyte proliferation by anticardiolipin antibodies was shown not to be caused by an alteration of T cell subpopulations. However, the interleukin 2 receptors on the cell surface and the soluble interleukin 2 receptors in ...

To the Editor: Misra and colleagues (1) reported an increased incidence of anticardiolipin antibodies in patients with infectious mononucleosis and postulated the existence of cross-reactions between infectious (viral) antigens and cardiolipin. We report here our experience concerning immunologic and biochemical similarities between Pneumocystis carinii organisms and cardiolipin. We observed that in the acquired immunodeficiency syndrome (AIDS), anticardiolipin antibodies occurred almost exclusively among those patients who had active P. carinii pneumonia (2). To test the cross-reactive hypothesis, we did several experiments.. In the first set of experiments, rabbits were immunized with an antigen from P. carinii in Freunds adjuvant prepared according ...
Hepatitis C, a worldwide viral infection, is an important health problem in Brazil. The virus causes chronic infection, provoking B lymphocyte dysfunction, as represented by cryoglobulinemia, non-organ-specific autoantibody production, and non-Hodgkins lymphoma. The aim of this research was to screen for the presence of antiphospholipid autoantibodies in 109 Brazilian hepatitis C virus carriers without clinical history of antiphospholipid syndrome. Forty healthy individuals were used as the control group. IgA, IgG, and IgM antibodies against cardiolipin and β2-glycoprotein I were measured with an enzyme-linked immunosorbent assay, using a cut-off point of either 20 UPL or 20 SBU. While 24 (22.0%) hepatitis C carriers had moderate titers of IgM anticardiolipin antibodies (median, 22.5 MPL; 95%CI: 21.5-25.4 MPL), only three carriers (,3%) had IgG anticardiolipin antibodies (median, 23 GPL; 95%CI: 20.5-25.5 GPL). Furthermore, IgA anticardiolipin antibodies were not detected in these individuals. ...
Background: Graves disease is an autoimmune disease, characterized by the presence of antibodies directed to TSH receptor or nearby regions as well as antibodies to double strands DNA (dsDNA) anticardiolipin and nuclear antibodies. This study evaluated anticardiolipin and rheumatoid factor, such as IgA and IgM antibodies in patients with Graves disease. Patients and methods: Anticardiolipin and rheumatoid factor were measured in sera of 84 patients (29 male, 55 female) with evidence of Graves disease and 41 healthy individuals (15 male, 26 female) with negative history of hyperthyroidism and other autoimmune diseases. Results: Mean level of anti cardiolipin antibody (ACLA) in patients and control groups were 0.192±0.11 and 0.087±0.200 optical density (OD) respectively. The level of IgM-Rhematoid factor (IgM-RF) of patients and healthy control groups was the same, whereas the mean IgA-RF levels in patients was significantly lower than control group. Conclusion: Anticardiolipin level in different
Our data suggest that subsequent thrombo-occlusive events and death after focal cerebral ischemia may occur sooner and more frequently in patients found to have IgG aCL immunoreactivity ,40 GPL units at the time of their index focal cerebral ischemic event when compared with patients who harbor 10 to 40 GPL at the time of their index event. Therefore GPL ,40 may be an important prognostic marker for subsequent thrombo-occlusive events in patients with index focal cerebral ischemia. Patients with ,40 GPL also appear to have more features of the antiphospholipid syndrome: younger age at onset and more recurrent strokes at the time of diagnosis.21 Furthermore, being in the GPL ,40 group appears to confer a sixfold-increased risk of developing subsequent TIAs only compared with being in the GPL ≤40 group. TIAs do not generally have as equally bad an outcome as ischemic stroke, although many hemispheric TIAs are minor infarcts by persistent subtle signs or neuroimaging abnormalities, and cognitive ...
Anticardiolipin antibodies (aCL) derived from the sera of individuals exhibiting the antiphospholipid syndrome (APS) directly bind to beta 2-glycoprotein I (beta 2-GPI), which is adsorbed to an oxidized polystyrene surface. Oxygen atoms were introduced on a polystyrene surface by irradiation with electron or gamma-ray radiation. X-ray photoelectron spectroscopy revealed the irradiated surfaces were oxidized to generate C-O and C = O moieties. aCL derived from either APS patients or (NZW x BXSB)F1 mice bound to beta 2-GPI coated on the irradiated plates, depending on the radiation dose. Antibody binding to beta 2-GPI on the irradiated plates was competitively inhibited by simultaneous addition of cardiolipin (CL)-coated latex beads mixed together with beta 2-GPI but were unaffected by addition of excess beta 2-GPI, CL micelles, or CL-coated latex beads alone. There was a high correlation between binding values of aCL in sera from 40 APS patients obtained by the anti-beta 2-GPI enzyme-linked ...
Dont be scared! There a a lot of us walking around with these antiphospholipid antibodies that never affect our health. It isnt known why in maybe a third of us that has them they suddenly play up. They can even appear in pregnancy and disappear afterwards. Either the anticardiolipin tests or the lupus anticoagulant can be positive at any time or negative. Thats why both tests are usually done together. Levels can vary too just as the body goes about its normal business so both tests need to be done at an interval of at least 6-8 weeks to see if they are constantly present and at what levels. They are not always due to autoimmune disease either. Leverls can be abnormal in infectious or other diseases so often certain tests are also done which indicate if they are autoimmune in ...
Although raised levels of aPLs were first reported in patients with autoimmune diseases, their presence is now known to be more widespread.1 Elevated serum levels of all three aCL isotypes, IgG, IgM, and IgA, have been reported in human infections caused by bacteria, viruses, spirochetes, and parasites; a higher prevalence of the IgG aCL isotype has been found in syphilis, HIV, tuberculosis, Q fever, Lyme disease, and cytomegalovirus infections.15 The mechanism of the aCL response to chronic infection such as that caused by HIV-1 and HCV is unclear. Infection induced aCLs have been shown to differ from autoimmune aCLs. The former tend to be transient, of low titre, and more often of the IgM isotype; in contrast, autoimmune aCLs often have highly sustained rather than transient titres, and are more often of the IgG isotype.15 21 Prieto et al 13 reported the presence of IgG aCLs in 22% of HCV infected patients. This contrasts with a previous report by Gotoh and Matsuda,22 who found significantly ...

My GP kindly agreed to Level 1 tests which I had arranged in February to ensure that I had the results before seeing Dr Gorgy. The tests were for lupus anticoagulant, natural killer cells, rheumatoid arthritis, thyroid function, anticardiolipin antibodies, FSH, LH and oestradoil. The last 3 tests are not very useful because they were done on day 13 of my cycle because my GP insisted that it wasnt necessary to do this on days 2 to 4 of cycle as I had requested. Ive been told on the phone that all the tests were normal but I requested copies of the test results which I received yesterday. Looking at the results, if I read it correctly, I think they forgot to send blood specimen for the lupus anticoagulant. WTF?!? Also, it showed a bunch of tests that didnt look anything like the Level 1 immune tests I did previously in 2008 or the named tests. Maybe Dr Gorgy will make some sense of it all ...

I am feeling a roller coaster of feelings, right now: Relief, irritation, frustration, love, joy, regret, blah…. Last week my cardiologist drew 9 vials of blood to see if we can get to the bottom of my blood clots prior to repairing my shunt. There have been some things consistently out of whack, so he wanted sort that out before he does my procedure on November 1st. He called me with the test results yesterday morning. Two things concerned him. One is the anticardiolipin antibody IGM, which has been in the moderate range all three times. The other is Factor V Lieden. Both things cause blood clots. The IGM also attacks the blood vessels, cell walls and heart valves, which could be causing my hemolytic anemia, hemolysis and the three funky heart valves… So hes now sending me to a hematologist to get me on the right medications before my procedure. The major concern is that r-l shunt is allowing blue blood, clots and bacteria to skip the filtration of the lungs and go to the brain and ...
August 15, 2012: We consulted with a fertility doctor who specializes in artificial insemination (also called IUI). He ordered a lot of blood work and procedures for me to finish out the diagnosis for my side of things. So far, I know that my estradiol and FSH are good. I also know that I am heterozygous for the MTHFR gene, which is involved with blood clots. That gene puts me at a higher risk for developing blood clots, but it turns out that another of my factors is wonky (will update when I know the name Update: It is the anticardiolipin antibody IGM that is elevated.) is a more significant risk. I also had an x-ray today (8/22) called an HSG. They injected contrast dye into my business and x-rayed to make sure that all my tubes and uterus are open and inviting. Good news--they are. We are still waiting on some of the blood work to come back (including my CF gene testing). Current medications: Prenatal with DHA, Vitamin D, Calcium, MTHFR capsule. Also, he explained why we would need to ...

A cautious yes from your MFM is good news! My MFM said that if she was just looking at my risk of PE based on my current kidney disease, she would say it was about a 1/3 chance of getting it. However due to my previous history of early severe PE, she puts the risk at about 2/3 but cant predict if it would be early again or later. Im kind of sad about those odds, but I understood that was probably the situation even before I had this visit. She did say that in my favor, the blood pressure and kidney disease have been well-controlled and my hypothyroidism is being treated (last time I didnt know about any of these issues until after I was pregnant) which may result in a better outcome. So like your MFM, she gave a cautious yes. I had the same labs drawn as you did and am waiting for the results which should be in on Wednesday. I already had the anticardiolipin labs done a few months ago and those were negative. I also did a repeat 24 hour urine for creatinine clearance and protein and am ...

OBJECTIVE To determine the prevalence of cardiac valvular involvement in patients with the primary antiphospholipid syndrome. DESIGN Cross-sectional study with evaluation of case patients and control patients by Doppler echocardiography. The mean follow-up for case patients was 22 months. SETTING University-based tertiary medical center. PATIENTS Twenty-eight consecutive patients who were diagnosed with the primary antiphospholipid syndrome during a 10-year period; 28 age- and sex-matched healthy controls. MEASUREMENTS AND MAIN RESULTS Ten patients (36%; 95% Cl, 19% to 56%) with the primary antiphospholipid syndrome had cardiac valvular involvement: Four patients had mitral valve involvement; four patients, aortic valve involvement; and two patients, both mitral and aortic valvular involvement; no patients had tricuspid or pulmonary valve disease. Eight of 10 patients had a regurgitant murmur. None of the control patients had valvular disease. The mean mitral valve thickness in patients with
Abstract: The confirmation of diagnosis of the Antiphospholipid Syndrome (APS) relies on laboratory tests. Current classification criteria for definite APS mandate the use of three "standardized" laboratory assays to detect antiphospholipid antibodies (aPL) [viz: anticardiolipin (aCL) IgG and IgM, anti-β(2) glycoprotein I (anti-β(2) GPI) antibodies IgG and IgM and/or a lupus anticoagulant (LAC)], when at least one of the two major clinical manifestations (thrombosis or pregnancy losses) are present. Although International Consensus Guidelines for the determination of LAC have been published and revised, the existence of "standardized" tests for detection of aCL and anti-β(2) GPI has remained elusive. In spite of the publication of several proposals, consensus documents and expert opinions, significant inter-assay and inter-laboratory variation in the results of both aCL and anti-β(2) GPI testing still exists, which affects the consistency of the diagnosis of APS. At the 13(th) International ...
Six cases of congenital thrombophilia (15%) were found: 1 PC deficiency (patient 25), 1 PS deficiency (patient 34), and 4 heterozygous factor V Leiden (patients 21, 22, 28, and 30). Three patients had increased aCL antibodies, 1 with systemic lupus (patient 21) and 2 with a primary aPL syndrome (patients 8 and 22); 2 of these had also factor V Leiden mutation. There was no antithrombin or plasminogen deficiency. Cases with thrombophilia and/or aCL antibodies are briefly summarized. Treatment and outcome are not detailed because all patients received heparin followed by oral anticoagulants and made an uneventful recovery.. Patient 25 was 34 years old in 1986 when she complained of headache, seizures, and left-sided sensory symptoms in a context of uveomeningitis. No other signs of Behçets disease11 or sarcoidosis were present. Angiography and MRI showed right LS thrombosis. The patient has been well since then. While receiving oral anticoagulants, PC activity was 24%, antigen was 33%, and ...
We evaluated inter-assay variation in anticardiolipin antibody status, comparing three centres, and using different assays among 36 women with recurrent miscarriage and 26 controls. There was no more agreement between the laboratories than would be predicted on the basis of chance for IgM and only fair agreement among the laboratories for IgG. None of the tests were significantly more likely to be positive in the cases compared with the controls ...
Recurrent pregnancy loss (RPL) can be defined as more than two to three consecutive miscarriages before 24 weeks gestation. A literature review was done to provide an evidence-based approach to RPL, identifying the risk factors and causes and also looking at the various special investigations that form part of the work-up and trying to assess which have been proven to be effective or of negative impact, and which of the management options lead to a better outcome. We concluded that the following special investigations should be part of the work-up for all patients with RPL: (i) genetic counselling and karyotyping of the abortus; (ii) anticardiolipin antibodies and lupus anticoagulant testing must be done on two occasions, 6 - 8 weeks apart; (iii) all patients qualify for a pelvic ultrasound scan and hysteroscopy; (iv) syphilis testing must be done routinely; and (v) testing of thyroid function and glucose monitoring/glycosylated haemoglobin (HbA1c) measurement must be done in all patients with ...

Results. In patients with suspected systemic rheumatic diseases, 72% satisfied American College of Rheumatology classification criteria: 40 (36%) had rheumatoid arthritis (RA), 16 (15%) systemic lupus erythematosus, 8 (7%) scleroderma, 8 (7%) osteoarthritis, 4 (4%) fibromyalgia, 2 (2%) seronegative spondyloarthropathy, 1 Sjögrens syndrome, and 1 sarcoidosis. Compared to controls, RA patient sera were more likely to contain anti-CCP (55% vs 2%; p , 0.001) or RF IgM antibodies (57% vs 10%; p , 0.001); however, the difference was greater for anti-CCP. Anti-CCP positivity conferred higher disease activity scores (DAS28 5.6 vs 4.45; p = 0.021) while RF positivity did not (DAS28 5.36 vs 4.64; p = 0.15). Anticardiolipin antibodies (25% of rheumatic disease patients vs 10% of controls; p = 0.0022) and ANA (63% vs 21%; p , 0.0001) were more common in rheumatic disease patients. ...

Antiphospholipid antibodies occur in various clinical states, including the primary antiphospholipid syndrome. Clinical features in these conditions appear to be caused by vasculopathy associated with the presence of these antibodies.. We report the case of a patient with primary antiphospholipid syndrome who experienced cardiac necrosis secondary to myocardial microvasculopathy in the absence of vasculitis. This case demonstrates unequivocally that noninflammatory myocardial microvasculopathy occurs in the primary antiphospholipid syndrome per se without any clinical or immunologic signs of systemic lupus erythematosus or other disease process. The histopathologic findings in the skin and myocardial biopsies showed a noninflammatory vasculopathy characterized by bland thrombi and lack of infiltration of the vessel wall by inflammatory cells. Ultrastructural examination of the myocardial biopsy confirmed the vascular thrombosis and endothelial activation and showed no deposits in basement ...
Antiphospholipid syndrome is an autoimmune disease, in which "antiphospholipid antibodies" (anticardiolipin antibodies and lupus anticoagulant) react against proteins that bind to anionic phospholipids on plasma membranes. Like many autoimmune diseases, it is more common in women than in men. The exact cause is not known, but activation of the system of coagulation is evident. Clinically important antiphospholipid antibodies (those that arise as a result of the autoimmune process) are associated with thrombosis and vascular disease. The syndrome can be divided into primary (no underlying disease state) and secondary (in association with an underlying disease state) forms. Anti-ApoH and a subset of anti-cardiolipin antibodies bind to ApoH, which in turn inhibits Protein C, a glycoprotein with regulatory function upon the common pathway of coagulation (by degradating activated factor V). Lupus anticoagulant (LAC) antibodies bind to prothrombin, thus increasing its cleavage to thrombin, its active ...

Antiphospholipid antibody syndrome is a fascinatingly complex disorder. It is an autoimmune disease, whereby the immune system attacks our own tissues. This article summarises the basic mechanisms of the condition and main diseases it is involved in. Learn about the diverse effects antiphospholipid antibody syndrome (APS) can have, from heart attack to miscarriage and how APS can be treated.
Antiphospholipid Antibody Syndrome (APS) is a highly prevalent cause of antibody-mediated thrombosis manifesting in venous thrombosis (DVT and PE), arterial thrombosis (most commonly stroke), and pregnancy complications. The diagnosis of definite APS requires both clinical and laboratory criterion as established by the working group of the International Congress on Antiphospholipid Antibodies (based on expert opinion). Since thrombosis and pregnancy loss are common in the general population, and antiphospholipid antibodies (aPL) occurs in a small percentage of the healthy public, it is important to demonstrate antibody persistence in patients who have the proper clinical indications in order to avoid misdiagnosis. Unfortunately, laboratory testing in this area lacks standardization, resulting in wide inter-laboratory variance. However, due to the commercialization of tests and automation, inter-laboratory variance has improved. Data on several new non-criterion tests suggest that they may ...
BACKGROUND Antiphospholipid syndrome (APS) is an autoimmune systemic disease characterized by vascular thrombosis (arterial or venous) and/or pregnancy complications associated with the occurrence of autoantibodies, specifically lupus anticoagulant, anticardiolipin antibodies, and/or anti-β2 glycoprotein-I antibodies confirmed at least twice over a 12 week period according to the 2006 Sydney criteria. Antiphospholipid antibodies are encountered in the general population with a reported prevalence of 1% to 5% However, APS is far more infrequent with a prevalence of 40-50/100,000 persons and an incidence of about 5 new patients/100,000 persons. APS can be diagnosed in patients with no apparent clinical or laboratory pathology (primary APS) or it may be related to numerous other conditions, autoimmune diseases (usually systemic lupus erythematosus), malignancies, infections and drugs (secondary APS). Women are at risk for APS since the disease is encountered in both the primary and the secondary state
New life-saving treatments for Antiphospholipid syndrome in clinical trial on Genetic Risk Factors Associated With Antiphospholipid Antibody Syndrome
Mycoplasma penetrans, a rare bacterium so far only found in HIV-infected persons, was isolated in the blood and throat of a non-HIV-infected patient with primary antiphospholipid syndrome (whose etiology and pathogenesis are unknown).
Antiphospholipid syndrome (APS) is an autoimmune disease characterized by the presence of antiphospholipid antibodies, such as lupus anticoagulant, anticardiolipin antibodies and anti-β2-glycoprotein 1 antibodies. APS can present with a variety of clinical phenotypes, including thrombosis in the veins, arteries and microvasculature as well as obstetrical complications. The pathophysiological hallmark is thrombosis, but other factors such as complement activation might be important. Prevention of thrombotic manifestations associated with APS includes lifestyle changes and, in individuals at high risk, low-dose aspirin. Prevention and treatment of thrombotic events are dependent mainly on the use of vitamin K antagonists. Immunosuppression and anticomplement therapy have been used anecdotally but have not been adequately tested. Pregnancy morbidity includes unexplained recurrent early miscarriage, fetal death and late obstetrical manifestation such as pre-eclampsia, premature birth or fetal ...

The fasting glucose and insulin concentrations, HOMA insulin resistance (IR), HOMA β-cell, antidouble-stranded DNA antibodies (anti-dsDNA), C3, C4, and SLE disease activity index (SLEDAI) were determined in a total of 58 female SLE patients. All patients were classified into subgroups according to the presence of anticardiolipin antibodies (aCL + vs. aCL-) and SLEDAI scores (SLEDAI , 3 vs. SLEDAI , 3). Results showed that SLE patients with and without aCL had significantly higher fasting insulin levels, HOMA IR, and HOMA ...
Results. Twenty-one patients were included. Diagnosis of BD was based on the criteria of the International Study Group for BD. Main locations for thrombosis were the cerebral sinuses, in 11 patients (52.4%); and lower limbs, in 9 patients (40.9%). Recurrent episodes were observed in 4 patients (21%). Thrombophilia measurements were normal in 14 patients out of 21, while anticardiolipin antibodies were positive in 4 patients, and 2 out of 21 had protein C deficiency. One patient had lupus anticoagulant. All patients were treated with colchicine. Corticosteroids were also added for variable periods in 13 patients. Five patients out of 21 were treated with anticoagulants (heparin, then anti-vitamin K) and 3 with antiplatelets (acetylsalicylic acid). ...
By Kristin Bendikson, MD. When a woman has a miscarriage, she often feels isolated and alone. Miscarriages are more common than most people realize, however; and when women start talking with their friends, they often find that they are not alone in coping with this difficult experience.. A miscarriage-the early loss of a pregnancy-occurs in approximately 15 percent of all clinically recognized pregnancies. If all pregnancies are accounted for, the statistic is closer to 50 percent ending in a loss. The increase is due to the fact that many women dont even know they are pregnant and experience their period at the normal time or just a few days late. Sometimes a woman knows she is having a miscarriage because she has symptoms, which might include bleeding and cramping followed by the passage of the pregnancy. Other times a woman doesnt sense there is anything wrong at all, and she finds out that the pregnancy has stopped growing only when she sees her doctor for an ultrasound.. Its important ...

We report in Figure 2 the annual rate (∼ 0.4%) of first cardiovascular event (including VTE) in normal white population at 35 to 55 years of age,14 that (1.36%) of 125 single aPL positive carriers with a mean age of 41 years (data taken by a recently published study by our group),15 and that (5.3%) of triple-positive carriers of this study (mean age, 45 years). Annual rate in a cohort of SLE patients half of whom had aPL was 2.9 per 100 patient-years.16 Hence, because less than half of our cohort had autoimmune disorders, the higher incidence of TEs recorded in this study may be related to the selection of high-risk aPL-positive population. Likewise, in patients with APS and triple positivity,7 TEs were equally distributed among arterial and venous circulation. Some patients in this study were treated with aspirin for primary thromboprophylaxis, behavior that did not lead to a significant reduction of events. To our knowledge, only one prospective clinical trial addresses the question of ...
My husband and I lost our baby boy last June and are thinking about trying again. My husband and family members are a little nervous about the thought of trying again. I have to tell you I am nervous too. I was so sick and out of it that I really have little or no memory of what when on around me. I had eclampsia and HELLP at 21 weeks. After having testing done I found out I have anticardiolipin and a high rheumatoid factor. We wanted to see if anyone in the Ohio group is from Columbus and has visted a MFM or high risk doctor and what you thought of them. I think due to the rules of the website you will have to e-mail me with your response because we can not name doctors or hospital in the forums. ...

I. Molecular Pathology Tests (New codes 812XX through 81408). Pricing the Tier 1 and Tier 2 molecular pathology codes for CY 2013 is an enormous undertaking in the short amount of time CMS plans to allot to contractors. The agency postponed pricing the tests last year because of the complexity of the task, and the job has not diminished in size. However, CY 2013 begins in just a few months, and neither the agency nor laboratories want to see a lengthy delay in claims processing for molecular pathology tests. Furthermore, regardless of the size of the task, the process should be transparent and should include the participation of interested stakeholders. These circumstances call for a straightforward pricing approach that utilizes information already available to CMS and contractors and that results in as little disruption as possible for stakeholders in the process.. A. The Molecular Pathology Test Codes should be Cross-walked to Existing Codes. ACLA disagrees with CMSs preliminary payment ...

Catastrophic Antiphospholipid Antibody Syndrome (CAPS) is a rare condition in which life-threatening blood clots form in multiple organs simultaneously and can lead to multi-organ system failure and death. The causes of CAPS are not entirely understood, but CAPS episodes are often triggered by stressful events such as infections, surgery, or trauma. For patients who survive an episode of CAPS, permanent kidney failure is not uncommon because the kidneys are the organ system most frequently affected in CAPS. Kidney transplantation is the treatment of choice for end-stage kidney disease, but patients with a history of CAPS are exceptionally high-risk kidney transplant recipients because the chance that surgery itself could trigger a life-threatening or transplant-threatening episode of CAPS is significant. As a result, patients with CAPS are not generally considered candidates for transplantation. Despite this, these patients have a severely decreased life-expectancy on dialysis and their ...

PURPOSE OF REVIEW: Laboratory criteria for the classification of antiphospholipid syndrome include the detection of a lupus anticoagulant and/or anticardiolipin and anti-β2-glycoprotein I antibodies. However, the majority of patients who test positive in these assays do not have thrombosis. Current risk-stratification tools are largely limited to the antiphospholipid antibody profile and traditional thrombotic risk factors. RECENT FINDINGS: Novel biomarkers that correlate with disease activity and potentially provide insight into future clinical events include domain 1 specific anti-β2GPI antibodies, antibodies to other phospholipids or phospholipid/protein antigens (such as anti-PS/PT), and functional/biological assays such as thrombin generation, complement activation, levels of circulating microparticles, and annexin A5 resistance ...

Systemic lupus erythematosus in the elderly: clinical and immunological characteristics. Isotype distribution of anticardiolipin antibodies in systemic lupus erythematosus: prospective analysis of a series of 100 patients
Recent advances allow us to propose antibodies targeting beta-2-glycoprotein I (β2-GPI) as the most specific antibodies associated with anti-phospholipid syndrome (APS). Therefore, there is now a crucial need for powerful biological assays to adequately monitor them. It is well established that these antibodies recognize mainly cryptic epitopes, which requires a great deal of consideration in the choice of laboratory tests to identify these antibodies. To this end, an update on the pathophysiological role of β2-GPI and a meta-analysis were conducted providing an overview of the current progress towards anti-β2-GPI detection.
A 32-year-old woman was admitted for mild gait difficulty and behavioural changes of 3 years duration. Familial and medical histories were unremarkable. Neurological examination revealed: mildly slowed gait, decreased synkinesias of the left arm (held abducted and flexed), increased deep tendon reflexes, Babinski signs, mild lower limb spasticity and dysmetria of left limbs. Depression and mild executive dysfunctions were also found.. Brain CT showed cerebral white matter (WM) calcifications (fig 1). MRI revealed T2 WM hyperintensities in the centra semiovalia, around the frontal horns and, to a lesser extent, in the posterior regions. Post-contrast MRI demonstrated points and stripes of enhancement in the periventricular WM, which are consistent with engorged medullary vessels (fig 2). Proton ...

N2 - We recently identified CD4+ T cells that are autoreactive to β2-glycoprotein I (β2GPI) and that promote antiphospholipid antibody production in patients with antiphospholipid syndrome (APS). In this study, T-cell receptor (TCR) β chains of β2GPI-reactive T cells were examined in 8 β2GPI-responders, including 5 patients with APS and 3 healthy subjects, using polymerase chain reaction and single-strand conformation polymorphism (PCRSSCP) analysis combined with in vitro stimulation of peripheral blood T cells with recombinant β2GPI. The TCR Vβ segments that expanded oligoclonally after stimulation with β2GPI varied among responders, but the Vβ7 and Vβ8 segments were commonly ...

A woman in her thirties suffered from lupus and antiphospholipid antibody syndrome (APS), an autoimmune, hypercoagulable disorder caused by antiphospholipid antibodies, which attack and damage tissues and cells and cause blood clots to form in the bodys arteries and veins. The woman took several anticoagulant medications as a result of a stroke she suffered at age 20. She suffered another stroke and was admitted to the hospital. She was treated at the hospital for approximately three months. About a month into her stay she underwent a kidney biopsy. After the kidney biopsy she was again administered blood-thinning therapy, including the medication Lovenox. Several days after the kidney biopsy, the woman suffered a large hemorrhage from the area of the biopsy kidney, which had become infected. As a result, the woman developed renal and respiratory failure, multiple abscesses, aspiration pneumonia, and other serious injuries and complications for which she continues to require inpatient treatment years

For decades, scientists and clinicians have been puzzled by an autoimmune condition, antiphospholipid syndrome (APS), which causes devastating health problems including uncontrolled blood clots and repeated pregnancy loss. Recent studies have shown that naturally produced antibodies that bind to phosphatidylethanolamine (PE) are positively correlated to antiphospholipid syndrome.. Phosphatidylethanolamine (PE), a lipid that makes up 20% of the inner cell membrane, has roles in membrane trafficking and reorganization. Paradoxically, the antibodies that bind to PE (anti-PE antibodies) in APS patients are produced outside of cells. This raises the question of how do the anti-PE antibodies bind to PE without having access to their targets? To unravel this mystery, Chemistry of Life Processes Institute faculty member and Northwestern Medicine investigator Ming Zhao (cardiology) synthesized special molecular probes to investigate the dynamic distribution of PE in living cells under the microscope. The ...

35 mm film (millimeter) is the film gauge most commonly used for motion pictures and chemical still photography (see 135 film). The name of the gauge refers to the width of the photographic film, which consists of strips 34.98 ±0.03 mm (1.377 ±0.001 inches) wide. The standard negative pulldown for movies ("single-frame" format) is four perforations per frame along both edges, which results in 16 frames per foot of film. For still photography, the standard frame has eight perforations on each side. A variety of largely proprietary gauges were devised for the numerous camera and projection systems being developed independently in the late 19th century and early 20th century, ranging from 13 mm to 75 mm (0.51-2.95 in), as well as a variety of film feeding systems. This resulted in cameras, projectors, and other equipment having to be calibrated to each gauge. The 35 mm width, originally specified as 1.375 inches, was introduced in 1892 by William Dickson and Thomas Edison, using 120 film stock ...
