    Secondary hemophagocytic lymphohistiocytosis (sHLH) is rare and has a high mortality rate, complicating diagnosis and prognostication.

  • 2

    Ruzicka et al. conducted a multicentric study with 167 adult sHLH patients, achieving strong predictive model performance for disease severity and mortality.

  • 3

    The study introduced the Initial Disease Severity (IDS) endpoint, serving as an early indicator of disease progression and care escalation.

  • 4

    sIL-2R was identified as a significant predictor of IDS and mortality, though its availability was limited to 40% of the patient sample.

  • 5

    Generative synthetic data augmentation may enhance training sets and address site-specific heterogeneity in rare disease research.
