Morbidity, Mortality, and Organ Damage in Patients with Antiphospholipid Syndrome
Bibliographic record
Abstract
OBJECTIVE: To describe morbidity, organ damage, mortality, and cause of death in patients with antiphospholipid syndrome (APS). METHODS: Descriptive analysis of 135 patients. Patients were clustered according to initial event: arterial thrombosis including stroke (AT; n = 46), venous thrombosis including pulmonary emboli (VT; n = 53), or pregnancy morbidity (PM; n = 36). Disease progression according to initial event and prevalence of organ damage was observed. RESULTS: APS occurs among young individuals (mean age 33.3 ± 11.9 yrs). One-third of the patients have APS secondary to systemic lupus erythematosus (SLE) or SLE-like disease. A broad spectrum of clinical manifestations mark the disease onset even before diagnosis. The pattern of initial presentation is preserved with regard to second event; VT is followed by VT (84%), AT is followed by AT (95%), and PM is followed by PM (88.9%). The highest morbidity is attributed to neurologic damage. PM is more likely to be followed by a second event, yet is associated with less organ damage than AT and VT. After a mean followup of 7.55 years, 29% of patients experienced organ damage and 5 died, with Systemic Lupus International Collaborating Clinics score associated with increased mortality (HR 1.31, 95% CI 1.07-1.60, p = 0.01, per 1-unit increase); hematological malignancies occurred in 2 patients after a cumulative followup of 1020 person-years. Coexistent SLE adds significant damage in patients with APS. CONCLUSION: APS is a disease of young individuals, who experience increased morbidity. Neurologic damage is the most common cause of morbidity. AT at presentation as well as coexistent SLE are associated with poor outcome.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
