[Phospholipid antibodies (lupus anticoagulant and cardiolipin antibodies). Detection and clinical significance].

Phospholipid antibodies may be detected by their ability to prolong phospholipid dependent coagulation tests, and are then called lupus anticoagulants. When ELISA tests with cardiolipin as coating antigen are used, the term anticardiolipin antibodies is employed. The association with thrombosis is best documented in patients with systemic lupus erythematosus. However, the "antiphospholipid syndrome", i.e. repeated thrombotic episodes and/or foetal loss in combination with a high positive anticardiolipin antibody test and/or an unequivocally positive lupus anticoagulant test, may be seen in individuals without any known underlying disease. The article describes techniques for the detection of antiphospholipid antibodies and adequate processing and handling of plasma samples.

High prevalence of anti-cardiolipin antibody, C1q-, C3d-, and mRF-IgG immune complexes, and anti-nuclear antibody in hemophiliacs irrespective of infection with human immunodeficiency virus type 1.

We investigated the prevalence of various autoantibodies [anti-cardiolipin antibody (aCL), lupus anticoagulant (LA), immune complexes (ICs), anti-nuclear antibody (ANA), and anti-deoxyribonucleic acid antibody (aDNA)] in hemophiliac individuals with (n = 50) and without (n = 42) infection by human immunodeficiency virus type 1 (HIV-1). The positivity rate for ANA was similar in both groups, and none of the patients was positive for LA and aDNA. aCL was positive in 35 of 50 (70%) HIV-1-positive hemophiliac individuals and 33 of 42 (79%) HIV-1-negative hemophiliac individuals. However, the majority of the aCL was revealed to be beta 2-glycoprotein I independent, thus corresponding to a syphilis type aCL that does not cause the so-called antiphospholipid syndrome. A total of 39 of the 45 HIV-1 positive hemophiliac individuals (87%) and 34 of 41 HIV-1-negative hemophiliac individuals (83%) had at least one type of IC [C1q-, C3d-, and/or murine monoclonal rheumatoid factor (mRF)- IgG]. The mechanism producing various autoantibodies in hemophiliac persons irrespective of their HIV-1 status is still unclear, but pathogens (e.g., HIV-1, hepatitis B, and hepatitis C) and alloantigens in the blood products that these patients require may be possible candidates. The clinical significance of the presence of these autoantibodies and the underlying mechanisms involved both need to be clarified further.

[Antibodies to cardiolipin and tumor-associated antigens CA-125 and CA-19-9 in patients with ovarian tumors].

Antibodies to cardiolipin (ACL) were detected in 12 (35%) of 34 patients with tumors of the ovaries. 8 of 12 patients exhibited clinical signs of antiphospholipid syndrome, 9 (75%), 2 and 1 patients demonstrated isolated hyperproduction of IgG ACL, combined rise of IgG ACL and IgM ACL, IgM ACL, respectively. Most frequently ACL occurred in endometriosis of the ovaries and serous cystadenomas (50 and 60%, respectively). In 5 (42%) of 12 patients CA-125 antigen concentration was above the upper norm (35 U/ml), in 3 (25%) cases the level of CA 19-9 antigen was elevated. There were parallel changes of ACL concentration and tumor marker CA-125 before and after operation. Autoimmune origin of ovarian endometriosis is suggested.

Isotype distribution and clinical significance of antibodies to cardiolipin, phosphatidic acid, phosphatidylinositol and phosphatidylserine in systemic lupus erythematosus: prospective analysis of a series of 92 patients.

OBJECTIVE: To determine the prevalence and correlation with clinical manifestations of the IgG and IgM isotypes of antibodies to cardiolipin (aCL), phosphatidic acid (aPA), phosphatidylinositol (aPI) and phosphatidylserine (aPS) in patients with systemic lupus erythematosus (SLE). METHODS: Clinical and laboratory features of 92 consecutive unselected patients with SLE were prospectively studied over two years. aCL, aPA, aPI and aPS were determined by ELISA. RESULTS: aCL were detected in 34 (37%) patients, aPA in 26 (28%), aPI in 22 (24%), and aPS in 29 (32%). A significant association was found between the appearance of thrombosis and the presence of IgG aCL (p < 0.001) and IgG aPS (p < 0.05). A significant association was also found between thrombocytopenia and the presence of IgG aCL (p < 0.001), IgG aPA (p < 0.01), IgG aPI (p < 0.05), and IgG aPS (p < 0.001). The development of hemolytic anemia was associated with the detection of IgM aCL (p < 0.001), IgM aPA (p < 0.05), IgM aPI (p < 0.001), and IgM aPS (p < 0.01). CONCLUSION: We found a relatively high prevalence of aCL, aPA, aPI and aPS in our SLE population and confirmed the presence of a correlation between the IgG isotype of these antibodies and thrombosis and thrombocytopenia, and also between the IgM isotype and hemolytic anemia. These results demonstrate the variety of antiphospholipid antibodies that can be detected in SLE patients, as well as their association with the clinical manifestations of the antiphospholipid syndrome.

[Antibodies to cardiolipin and hemostasis in rheumatic patients during development of rheumatic valvular disease].

The observational study included 79 rheumatic patients aged 14-49 years. The diagnosis of acute rheumatic fever (ARF) was made in 29 patients (13-first attack, 16-recurrence), 50 patients had rheumatic heart disease (RHD) without signs of activity, 40 healthy donors served control. Antibodies to cardiolipin (a-CL) in the blood were determined by enzyme immunoassay, hemostasis was assessed by the level of antithrombin III, platelet aggregation, readings of electrocoagulograms. ARF patients were examined throughout the year, RHD patients--only once. Compared to the controls, both ARF and RHD patients demonstrated higher occurrence of a-CL, enhanced platelet aggregation, low antithrombin III level, hypercoagulation on electrocoagulogram, a-CL in ARF patients were detectable from the first month of the attack. By month 7-12 their count decreased, hemostasis normalized. In the onset and progression of RHD in the presence of ARF a-CL occurred more frequently. A direct relationship was found between the time of a-CL detection in the blood and severity, duration of rheumatic carditis. The data obtained validate feasibility of using a-CL for diagnosis of rheumatic carditis severity and prognosis of RHD development.
