Prognostic factors and clustering of serious clinical outcomes in antiphospholipid syndrome

Abstract

We assessed whether initial clinical presentations suggestive of antiphospholipid syndrome (APS) predicted the subsequent rate and type of serious clinical outcomes. Eighty-two consecutive patients with anticardiolipin antibodies or lupus anticoagulant were followed for 814 person-years after a first event suggestive of APS (livedo reticularis, thrombocytopenia, autoimmune haemolysis, thrombosis, central nervous system manifestations, recurrent abortions). The hazard of developing a second event was largest in patients with antibodies recognizing beta2 glycoprotein I who had autoimmune haemolysis as the first event (hazard ratio HR 2.70, p=0.018) and smallest in patients without such antibodies who had recurrent abortions as their first event (HR 0.37, p=0.028). Subsequent serious events in patients with venous and arterial thromboses, recurrent abortions, central nervous system manifestations and autoimmune haemolytic anaemia were likely to be of the same type as the presenting event (odds ratio (OR) 3.76, 5.90, 77.7, 6.92, and 7.13, respectively. Adjusting for therapy, the rate of subsequent serious events was 6.86-fold higher (p=0.0001) in patients presenting with two events, 1.56-fold higher (p=0.038) in autoimmune haemolysis presentations, 1.69-fold higher (p=0.004) in patients with anti-beta2-glycoprotein-I antibodies, and 46% (p=0.063) lower in thrombocytopenia presentations. Initial clinical features determine the long-term evolution of APS, and specific types of clinical manifestations cluster during the course of the disease.

  • Antiphospholipid syndrome patients with arterial thrombosis have a higher risk of recurrence compared with those with venous thrombosis, and a tendency for recurrences in the same vascular bed.

    “Patients with APS with arterial thrombosis have a higher risk of recurrence compared with those with venous thrombosis, and a tendency for recurrences in the same vascular (arterial) bed.34”

    From EULAR recommendations for the management of antiphospholipid syndrome in adults (2019) · cites this paper as [34]

    The ‘Clustering of similar clinical events’ section reports a tendency for subsequent thromboses to occur in the same vascular bed as the presenting thrombosis. It does not establish that patients presenting with arterial thrombosis have a higher overall recurrence risk than those presenting with venous thrombosis; its odds ratios measure same-type clustering against other presentations, not arterial-versus-venous recurrence risk.

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.
