Detaljeret beskrivelse
This is an observational, retrospective cohort study on the treatment utilization and outcomes of Macrophage Activation Syndrome (MAS) refractory to glucocorticoids (GC) in patients with Still's disease. The study will be conducted entirely through medical chart abstraction; all data will be taken from the patient's medical record, with no additional assessments.

- Diagnosis of MAS according to treating physician in the medical record.
- Patients who have received at least 3 consecutive days of GC after diagnosis of MAS and/or are judged by the Investigator to be refractory to GC due to clinical worsening of patient's condition .
- The onset of the index MAS episode occurred between 01 January 2012 and 30 September 2022.
Exclusion Criteria:
