🚨 POP QUIZ - Would you recognize the signs of HLH?
HLH (Hemophagocytic Lymphohistiocytosis) can look different from person to person, and its symptoms can overlap with other serious illnesses.
Possible signs can include:
• Persistent fever
• Enlarged spleen or liver
• Low blood counts
• Significant inflammation
• Changes in liver function
• Neurologic symptoms
• Other symptoms related to widespread immune activation
HLH is complex, and having one or more of these symptoms does not mean someone has HLH.
But understanding the condition can help individuals, families, and healthcare professionals recognize when further evaluation may be needed.
