An acute haemolytic crisis is a major complication of HbH disease that requires prompt emergency management. The clinical scenario and treatment goals are outlined below; the complete structured regimen is available via the link below.

Clinical scenario

Haemoglobin H disease presenting with acute haemolytic crisis: acute worsening of anaemia, frequently accompanied by jaundice and/or haemoglobinuria, and often triggered by infection or fever.
