Abstract

To assess the clinical significance of lupus anticoagulants (LAs) and antiphospholipid antibodies (aPLs) toward thrombosis and abortions, we measured them in 112 patients whose samples were available at enrollment in the warfarin in the antiphospholipid syndrome (WAPS) study. Enzyme-linked immunosorbent assay (ELISA) and coagulation test values in the highest and lowest tertiles were compared. When considered separately, IgG antibodies to β2-glycoprotein I (aβ2GPI) and prothrombin (aPT) were associated with anamnestic arterial and venous thrombosis, respectively, and those to annexin AV (aAnAV) with abortions. IgM antibodies to protein S and the lupus ratio of the dilute prothrombin time were associated with prospective thrombosis. No other association for IgM antibodies was seen. LA-positive patients who carried aβ2GPI antibodies were at risk of anamnestic arterial and total thrombosis and aPT antibodies to that of anamnestic venous and total thrombosis. LA-positive patients who carried IgG aβ2GPI and aAnAV antibodies were at risk for both anamnestic abortion and prospective thrombosis. Overall, these data support the inclusion of aβ2GPI antibodies in and suggest the removal of anticardiolipin antibodies from the laboratory criteria of the antiphospholipid syndrome. They also suggest that the measurement of aPT and aAnAV antibodies is useful in some selected situations and that there is little role for IgM antibody detection.

  • A considerable proportion of patients with LA will not develop thrombosis despite the presence of aPL-associated autoantibodies at high titers.

    “Further, a considerable proportion of patients with LA will not develop thrombosis despite the presence of aPL-associated autoantibodies at high titers [7].”

    From Cardiovascular risk factors are major determinants of thrombotic risk in patients with the lupus anticoagulant (2017) · cites this paper as [7]

    The section on IgG aPL antibodies in LA-positive patients reports that 32 of 38 patients with high aPT levels and 33 of 37 with high anti-β2GPI levels had a history of thrombosis; some in each group therefore had no such history. The Clinical characteristics section reports thrombosis during a median 3.67-year follow-up in 15 of 112 patients, but it does not establish that a considerable proportion of high-titer, LA-positive patients will never develop thrombosis.

  • While triple positivity has been shown to be a significant thrombotic risk factor in the WAPS study, several more recent prospective cohorts have also observed a lack of association between triple positivity or other LA-related autoantibodies and thrombosis.

    “While triple positivity has been shown to be a significant thrombotic risk factor in the WAPS study [7], several more recent prospective cohorts have also observed a lack of association between triple positivity or other LA-related autoantibodies and thrombosis [30, 32, 33].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
