Adult macrophage activation syndrome–haemophagocytic lymphohistiocytosis: ‘of plasma exchange and immunosuppressive escalation strategies’ – a single centre reflection

Abstract

Together, early use of PE is at most a supportive measure, not a promising monotherapy of adult MAS-HLH. In refractory cases, conventional cytoreductive therapies (i.e. cyclophosphamide and etoposide) constitute potent and reliable rescue approaches, whereas IvIG, anti-thymoglobulin, and biologic agents appear to be less effective.
