Comparison of cardiolipin and treponemal tests in the serodiagnosis of yaws.

Results of the Veneral Disease Research Laboratory (VDRL), rapid plasma reagin (RPR), Treponema pallidum haemagglutination (TPHA), T. pallidum immobilisation (TPI), and fluorescent treponemal antibody absorption (FTA-ABS) tests on sera of 661 children from a region where yaws is hypoendemic are compared. For 107 (16.2%) out of 661 sera the FTA-ABS test was the only one showing reactivity; in these instances the test was weakly reactive (intensity of fluorescence scored as +) and the children had no history and no signs or symptoms of treponemal disease. A solitary, weakly reactive FTA-ABS test result seems to have no clinical significance in these cases. The FTA-ABS test can be used as a confirmatory test for yaws instead of the TPI test, if only the results of sera showing an intensity of fluorescence scored as ++ or more are considered to be positive. There appeared to be no significant differences in the results of the VDRL, RPR, and TPHA tests as screening tests for yaws when the TPI or FTA-ABS tests were used as reference tests.

Coronary artery disease but not coronary calcification is associated with elevated levels of cardiolipin, beta-2-glycoprotein-I, and oxidized LDL antibodies.

BACKGROUND: Autoimmune factors have been shown to play a role in atherosclerosis. The aim of this study is to correlate 5 autoantibodies (anticardiolipin, anti-CL, beta2-glycoprotein-I, beta2GPI, phosphatidylcholine, oxidized low-density lipoprotein, oxLDL, endothelial cell) with the presence of coronary heart disease, angiographic findings, and with coronary artery calcification. METHODS: The levels of the 5 autoantibodies and a control antifibroblast line of 126 coronary heart disease patients and 20 healthy controls were measured. Fifty-one patients underwent coronary angiography, and 98 patients had coronary artery calcium determination using spiral computerized tomography (dual mode). RESULTS: Levels of 3 autoantibodies (anti-CL, beta2GPI, oxLDL) were significantly elevated in coronary heart disease patients compared with controls (p < 0.001, p = 0.001, p < 0.001, respectively). Within the subgroup of patients with significant coronary artery stenosis, anti-CL antibodies were also elevated (p = 0.008). No correlation was found between anti-CL, and anti-beta2GPI autoantibody levels and coronary calcium scores as measured by spiral computerized tomography. However, anti-oxLDL antibodies were raised in patients with no calcification detected by spiral computerized tomography, compared with the patients with any coronary calcification (p = 0.046). CONCLUSION: Anti-CL, beta2GPI and oxLDL antibodies are elevated in coronary heart disease patients regardless of coronary calcification.
