OBJECTIVES: To explore the clinical features, treatments, and prognostic factors of adult-onset Still's disease (AOSD)-associated macrophage activation syndrome (MAS), we conducted a multicenter retrospective clinical study of AOSD-associated MAS patients.
METHODS: AOSD patients were collected from six tertiary hospitals in China. Medical charts were reviewed and clinical information was recorded and analyzed.
RESULTS: There were 447 AOSD patients enrolled into this retrospective clinical study. Among them, 55 were diagnosed with MAS. Liver dysfunction was the most reliable predictive factor for the screening of MAS in AOSD patients (OR = 75.744, 95%CI = 23.015-249.284, p < 0.0001). In multivariate analysis, clinical features including platelets < 100 × 109/L (OR = 9.546, p = 0.005), aspartate transaminase (AST) > 120 U/L (OR = 25.853, p < 0.0001), triglycerides > 3 mmol/L (OR = 12.9833, p = 0.011)), ferritin > 1500 ng/mL (OR = 5.513, p = 0.050), as well as hemophagocytosis in bone puncture (OR = 18.132, p = 0.001) were highly associated with the occurrence of MAS. The mortality rate of total AOSD patients was 4.47%, MAS was the main cause of death in AOSD patients (OR = 11.705, 95%CI = 4.783-28.647, p < 0.0001). PLT ≤ 100 × 109/L (p = 0.0001), fibrinogen < 1.5 g/L (p = 0.0286), splenomegaly (p = 0.0002), and liver dysfunction (p = 0.0008) highly suggested poor prognosis.
CONCLUSION: MAS occurrence is the major cause of death in AOSD patients. Notable liver dysfunction, as well as splenomegaly, low number of platelets or neutrophils, high levels of serum ferritin, and reduced level of fibrinogen are risk factors for poor outcome. Key Points • This is a multicenter retrospective study of AOSD-associated MAS with large number of cases.
