Abstract

New clinical, laboratory and experimental insights, since the 1999 publication of the Sapporo preliminary classification criteria for antiphospholipid syndrome (APS), had been addressed at a workshop in Sydney, Australia, before the Eleventh International Congress on antiphospholipid antibodies. In this document, we appraise the existing evidence on clinical and laboratory features of APS addressed during the forum. Based on this, we propose amendments to the Sapporo criteria. We also provide definitions on features of APS that were not included in the updated criteria.

  • Positivity for polyreactive aCL antibodies is a classification criterion for APS and SLE.

    “Positivity for polyreactive aCL antibodies is a criterion in the classification of two autoimmune conditions: APS and SLE251,252.”

    From The role of mitochondria in rheumatic diseases (2022) · cites this paper as [252]

    The 'Update of the classification criteria' section identifies persistent, medium- or high-titer IgG or IgM aCL positivity as an APS laboratory criterion, with a specified positivity threshold. It does not identify polyreactivity as a criterion or establish aCL positivity as an SLE classification criterion; the SLE portion of the citing sentence may be supported by its other citation, but not by this paper. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • The Sydney criteria's 12-week interval rests on expert opinion, and knowledge about aPL persistence past 3 months is limited.

    “The interval of 12 weeks, defined in the Sydney criteria (previously 6 weeks in the Sapporo criteria), was based on expert opinion and little is known on persistence of aPL beyond 3 months.1”

    From Guidance from the Scientific and Standardization Committee for lupus anticoagulant/antiphospholipid antibodies of the International Society on Thrombosis and Haemostasis (2020) · cites this paper as [1]

    The Update of the classification criteria section says the Sapporo interval was 6 weeks, proposes 12 weeks, and explicitly states that the proposed time intervals are based on expert opinion. It calls for studies validating those intervals and describes relevant data as poor, but does not specifically say that little is known about aPL persistence beyond 3 months. (LLM, conf=0.83)

    Experimental — accuracy not yet measured
  • Patients with antiphospholipid antibodies are at increased risk of thrombosis or adverse pregnancy outcomes.

    “Patients with antiphospholipid antibodies (lupus anticoagulant, anticardiolipin and anti-beta 2 glycoprotein) are at increased risk of thrombosis or adverse pregnancy outcomes.1”

    From Evaluation of different ways to identify persistent positivity of lupus anticoagulant in systemic lupus erythematosus (2020) · cites this paper as [1]

    The ‘Update of the classification criteria’ section associates medium- or high-titer anticardiolipin antibodies with clinical manifestations of APS and reports that multiple antibody positivity increases thrombosis rates. Table 2 pairs persistent positivity for the named antibodies with thrombosis or pregnancy morbidity as APS criteria. The citing sentence omits those titer and persistence qualifications, so the paper does not establish increased risk for every patient with a positive antibody test. (LLM, conf=0.83)

    Experimental — accuracy not yet measured
  • The presence of 1 or more aPL for 12 or more weeks constitutes the laboratory criteria for APS.

    “The presence of 1 or more of these aPL for 12 or more weeks constitutes the laboratory criteria for antiphospholipid syndrome (APS), an autoimmune disorder defined clinically by arterial and venous thrombotic events and/or pregnancy complications.5”

    From Lupus anticoagulant test persistence over time and its associations with future thrombotic events (2022) · cites this paper as [5]

    The revised laboratory criteria (Table 2) require at least one qualifying aPL test to be positive on two or more occasions at least 12 weeks apart. The citing sentence captures the persistence requirement but omits the repeat-testing requirement and the specified antibody types and titer thresholds; presence of any aPL alone does not suffice. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Lupus anticoagulant results were reported as positive or negative by the MMC laboratory following International Society on Thrombosis and Hemostasis guidelines.

    “LAC was reported as positive or negative (LAC+/LAC−) by the MMC laboratory in accordance with the guidelines of the International Society on Thrombosis and Hemostasis (9).”

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.
