Antibodies to β2-glycoprotein I and clinical manifestations in patients with systemic lupus erythematosus

Objective. To investigate whether anticardiolipin antibodies (aCL) in patients with systemic lupus erythematosus (SLE) bind to β₂-glycoprotein I (β₂GPI), and to search for a relationship between the presence of IgG and/or IgM anti-β₂GPI antibody and clinical manifestations in SLE patients. Methods. IgG and IgM anti-β₂GPI in 308 Japanese SLE patients were measured using phospholipid-independent enzyme immunoassays. Relationships to clinical histories and to various laboratory data were examined. Results. The values of anti-β₂GPI and aCL, as measured by conventional enzyme immunoassay, showed a strong correlation, but the anti-β₂GPI assay was more useful in distinguishing β₂GPI-dependent aCL from β₂GPI-independent aCL. The presence of IgG anti-β₂GPI was associated with an increased frequency of a history of thrombosis. Comparisons of various laboratory data suggested that the titer of anti-β₂GPI may fluctuate with disease activity. Conclusion. The results suggest that pathogenic aCL is directed against structurally altered β₂GPI and that enzyme immunoassay for anti-β₂GPI may prove useful in evaluating the risk of thrombosis and monitoring the clinical course in patients with SLE.     

Anticardiolipin and anti-beta2GPI antibodies in a large series of European patients with systemic lupus erythematosus. Prevalence and clinical associations. European Concerted Action on the Immunogenetics of SLE

OBJECTIVE: To test the prevalences and the clinical associations of anticardiolipin (aCL) and anti-beta2GPI (abeta2GPI) antibodies in a large series of European patients with systemic lupus erythematosus (SLE). METHODS: 574 SLE patients from 7 European countries were tested for aCL and abeta2GPI by ELISA methods. RESULTS: aCL of IgG, IgM, and IgA isotypes were detected in 22.8%, 14%, and 13.9% of the patients, respectively. IgG and IgM abeta2GPI were detected in 20% of the patients. The presence of aCL was highly associated with the presence of abeta2GPI. Medium-high titer IgG aCL and abeta2GPI were associated with thrombosis, with similar sensitivity, specificity, and positive predictive value. When present at medium-high titer, IgG aCL were associated with thrombocytopenia, IgM aCL with hemolytic anemia, and cerebrovascular accidents. IgA aCL with livedo reticularis and Raynaud's phenomenon. CONCLUSIONS: aCL, when present at medium-high titer, are as important as abeta2GPI, as a risk factor for thrombosis. Medium-high titer aCL, but not abeta2GPI, are associated with other clinical features of the antiphospholipid syndrome.     

抗β_2糖蛋白Ⅰ型抗体与急性冠脉综合征相关性研究

目的：探讨抗β2糖蛋白I型抗体（抗β2 GPI抗体）与急性冠脉综合征（ACS）的临床相关性。方法：采用酶联免疫吸附法检测168例ACS患者血清中抗β2 GPI抗体的浓度水平,同时进行冠脉造影术检查,并对罪犯血管进行血管重建。根据抗体浓度水平分为高、中、低浓度组,分析各组中抗体浓度与ACS临床分型[急性ST段抬高型心肌梗死（STEMI）、急性非ST段抬高型心肌梗死（NSTEMI）、中危以上不稳定型心绞痛（UA）]的相关性,随访12个月,评价抗β2 GPI抗体浓度与ACS患者的疾病严重程度及主要不良心血管事件（MACEs）的相关性。结果：ACS中STEMI、NSTEMI、UA患者抗β2 GPI抗体浓度依次是（63.4±32.6）RU/ml,（39.8±25.9）RU/ml,（22.1±10.4）RU/ml,其中STEMI患者抗体浓度较高,UA患者的抗体浓度最低。抗β2GPI抗体的高浓度组中STEMI（10/11）占90.9%,高于中浓度组（29/96）和低浓度组（1/61）（P〈0.01）。随访观察12个月,随访率98%;抗β2 GPI抗体高浓度组有4例发生MACEs,发生率36.4%,显著高于中浓度组（4.2%）和低浓度组（3.5%）。多因素回归分析提示抗β2GPI抗体高浓度是预测ACS发生MACEs的独立危险因素之一。结论：抗β2 GPI抗体浓度与ACS患者疾病的严重程度及MACEs密切相关,抗β2 GPI抗体高浓度是ACS再发MACEs的独立危险因素之一。     

Significance of anticardiolipin and anti-beta(2)-glycoprotein I antibodies in lupus nephritis

OBJECTIVE: To investigate whether anticardiolipin (aCL) and anti-beta(2)-glycoprotein I (anti-beta(2)GPI) antibodies are associated with lupus nephritis (group II patients), and whether there are differences in the prevalence of these two autoantibodies between group II patients and patients with non-nephritis SLE (group I) and primary antiphospholipid syndrome (PAPS) patients (group III). METHODS: IgG and IgM aCL were measured in 31 patients and anti-beta(2)GPI in 30 patients with systemic lupus erythematosus (SLE) nephritis and 25 without SLE nephritis and in 36 PAPS patients by validated enzyme immunoassays. Relationships of anti-double-stranded DNA (anti-dsDNA) antibodies and antibodies to the collagenous region of C1q (anti-C1q) with SLE nephritis were also examined. RESULTS: The prevalence and levels were higher for aCL, but not for anti-beta(2)GPI, antibodies in group II than in group I patients. Absolute values of aCL and anti-beta(2)GPI in all three patient groups correlated with each other. The prevalences of aCL, anti-dsDNA and anti-C1q antibodies were significantly higher in group II than in group I and group III patients. CONCLUSION: The observations in this paper suggest that raised levels of aCL antibodies are associated with lupus nephritis. We were not able to demonstrate an association between anti-beta(2)GPI antibodies and kidney disease either in patients with lupus or in patients with primary antiphospholipid syndrome. In SLE, we demonstrated that the presence of anticardiolipin antibodies in conjunction with elevated levels of anti-dsDNA and anti-C1q antibodies is highly specific for glomerulonephritis in patients with lupus.

Anticardiolipin and anti-beta2glycoprotein-I antibodies in patients with systemic lupus erythematosus: comparison between Colombians and Spaniards

We studied the prevalence, isotype distribution, and clinical significance of anticardiolipin (aCL) and anti-beta2glycoprotein I (anti-beta2GPI) antibodies in two populations of patients with systemic lupus erythematosus (SLE), 160 Colombians and 160 Spaniards. All sera were tested in our laboratory by enzyme-linked immunosorbent assay (ELISA) for IgG, IgM, and IgA aCL, as well as IgG and IgM anti-beta2GPI. Positive results for at least 1 of the 3 aCL isotypes were found in 40 Colombians (25%) and 55 Spaniards (34%). IgG aCL was the predominant isotype in both populations. Positive results for at least 1 of the anti-beta2GPI isotypes were found in 34 Colombians (21%) and 29 Spaniards (18%). IgG anti-beta2GPI was the dominant isotype in Colombians, while IgM was predominant in Spaniards. Positivity for anti-beta2GPI in aCL-positive patients was present in 77% in the Colombian group and 50% in the Spaniard group. Among Colombians, IgG aCL and anti-beta2GPI correlated with thrombosis, fetal loss, and thrombocytopenia. Among Spaniards, IgG aCL and IgG anti-beta2GPI correlated with thrombosis, fetal loss, and livedo reticularis. For detecting thrombosis and fetal loss, aCL ELISA was more sensitive than anti-beta2GPI in Spaniards, and anti-beta2GPI ELISA was more specific than aCL in both populations.     

IgM autoagglutinins in warm autoimmune hemolytic anemia: a poor prognostic feature.

The presence of both complete IgM autoagglutinins and IgG autoantibodies in warm autoimmune hemolytic anemia (AIHA) is an uncommon finding. Over a 6-year period, only 5 of 115 (4.1%) patients with AIHA had IgM and IgG autoantibodies. In 3 of the 5 cases, the complete IgM autoagglutinins reacted up to 30 degrees C and these patients responded well to corticosteroid or other therapies for warm AIHA. The 2 patients who had warm (37 degrees C) reactive IgM autoagglutinins, were refractory to corticosteroids, splenectomy and cytotoxic drugs, and died due to the complications of hemolytic anemia. The data in these 5 cases suggest that the thermal amplitude of the IgM antibody in these unusual AIHA cases may be predictive of refractoriness to therapy and poor clinical outcome.     

Relations beetwen severity of anemia and certain antiphospholipid antibodies presence in systemic lupus erythematosus patients

Anaemia is a common hematological abnormality in systemic lupus erythematosus (SLE). Autoimmune hemolytic anaemia (AHA) is one of the types of anaemia in SLE. Other reasons of anaemia in SLE are: chronic inflammatory diseases, insufficient level of elements necessary for erythropoiesis and chronic renal disease. The aim of the study was to examine the relations between severity of anemia and presence of certain antiphospholipid antibodies (aPL) in SLE. The study group consisted of 24 patients (one man and 23 women) with active lupus. Anticardiolipin antibodies (aCL), anti-02 glycoprotein I antibodies (anti-beta2 GPI IgM and IgG) and red cell parameters: haemoglobin level (Hb), erythrocytes (RBC), mean corpuscular volume (MCV), mean corpuscular haemoglobin mass (MCH), mean corpuscular haemoglobin concentration (MCHC) and ferritin level were measured before beginning or intensification of treatment. The activity of SLE was measured by SLEDAI and C3 complements. The patients were divided into two subgroups: subgroup with aCL-IgG above 20 u/ml and below 20 u/ml. In patients with aCL-IgG above 20 u/ml the mean Hb level was lower, and the mean ferritin level was significantly higher than in patients with aCL-IgG level below 20 u/ml. We observed a negative, significant correlations between Hb and aCL-IgG (p = 0.01; R = -0.47) and between Hb and anti-32 GPI IgG (p = 0,0003; R = -0,67) and a negative correlation between Hb and activity of SLE estimated by SLEDAI (p = 0.02; R = -0.45) and positive between Hb and C3 complement (p = 0.02; R = +0.5). In conclusion: antiphospholipid antibodies presence in patients with SLE can influence the severity of anaemia.
