Abstract

Objective: Antiphospholipid antibodies (aPL), namely anticardiolipin antibodies (aCL) and lupus anticoagulant (LAC), have been associated with an increased risk of thrombosis in systemic lupus erythematosus (SLE). We examined additional thrombosis risk factors (aPL profile, SLE‐related, and traditional risk factors) and the primary thrombosis prevention in SLE patients with and without aPL. Methods: All SLE patients with positive aPL but without previous thrombotic manifestations who were regularly followed up at our department (n = 144) and 144 age‐ and sex‐matched SLE patients with negative aPL were included in this study. The median followup times were 104 and 112 months, respectively. The demographic, clinical, laboratory, and treatment characteristics and the traditional thrombosis risk factors were recorded. Results: The thrombosis rate was 29 per 144 aPL‐positive patients (20.1%) and 11 per 144 aPL‐negative patients (7.6%; P = 0.003). In multiadjusted analysis, significant predictors of thrombosis were male sex (hazard ratio [HR] 6.25, P < 0.01), LAC (HR 3.48, P = 0.04), and constantly positive aCL (HR 5.87, P = 0.01) for aPL‐positive patients, while male sex (HR 7.14, P = 0.03) and hypertension were predictors for aPL‐negative patients (HR 6.49, P = 0.03). Additionally, the duration of low‐dose aspirin treatment played a protective role against thrombosis in aPL‐positive patients (HR per month 0.98, P = 0.05), as did the duration of hydroxychloroquine in both aPL‐positive (HR per month 0.99, P = 0.05) and aPL‐negative patients (HR per month 0.98, P = 0.04). Conclusion: Independent predictors of thrombosis for aPL‐positive patients were male sex, LAC, and constantly positive aCL, and for aPL‐negative patients were male sex and hypertension. The duration of low‐dose aspirin use played a protective role against thrombosis in aPL‐positive patients as did the duration of hydroxychloroquine in both groups.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Prior retrospective and prospective studies have shown that hydroxychloroquine lowers the risk of arterial and venous thrombosis in systemic lupus erythematosus.

    “Multiple retrospective and a few prospective studies (3–13) have found that hydroxychloroquine (HCQ) reduces the risk of arterial and venous thrombosis.”
  • Some studies reported that the increased risk of thrombosis in SLE was associated with the presence of LA and with a persistently positive aCL.

    “Some studies reported that the increased risk of thrombosis in SLE was associated with the presence of LA and with a persistently positive aCL [41, 44].”
  • In systemic lupus erythematosus patients with a low-risk antiphospholipid antibody profile, pooled data from two cohort studies indicate that low-dose aspirin is associated with a lower risk of thrombosis.

    “Less evidence is available on the use of LDA in patients with SLE and low-risk aPL profile, but pooled data from two cohort studies indicate that the use of LDA was also associated with a lower risk of thrombosis in this group.16 17”

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.
