Hemophagocytic lymphohistiocytosis: new grading classification and targeted therapies

New severity grading and targeted treatments for a rare immune condition called hemophagocytic lymphohistiocytosis are improving recognition and management.

This review from New York Medical College proposes a novel CTCAE v5.0-based grading system for HLH incorporating key prognostic factors, addressing the longstanding absence of standardized HLH severity assessment. New targeted therapies (emapalumab, ruxolitinib, tocilizumab) and emerging options (IL-18 inhibitors, TNFα inhibitors) are summarized.
