“Early recognition and timely intervention are critical to improving outcomes in HLH/MAS.” Watch this masterclass, presented by Fabrizio de Benedetti, to deepen your understanding of the diagnosis, biomarkers, and treatment strategies for secondary hemophagocytic lymphohistiocytosis / macrophage activation syndrome (HLH/MAS). This three-part series offers expert insights into managing this often underdiagnosed, rapidly progressive, and life-threatening hyperinflammatory syndrome.

Watch now to:

  • Recognize the urgency of HLH/MAS and its potential for rapid clinical progression
  • Apply biomarker-driven stratification to assess disease severity and monitor treatment response
  • Assess how targeted therapies, including IL-1 inhibitors and IFN-γ blockade, are reshaping the treatment landscape for both pediatric and adult patients
