Herrick's syndrome

Related people

A haemolytic anaemia occurring almost exclusively in persons of Negro ancestry, chiefly characterised by the presence of sickle-shaped erythrocytes and a severe degree of anaemia. Women more often affected than men.

Onset takes place early in life after normal haemoglobin is replaced with sickle-cell haemoglobin. Symptoms include increased fatigability with sudden increase in weakness, severe pain in joints and elsewhere in extremities. Abdominal manifestations may resemble an acute abdomen, and occasionally well-marked neurologic features with changes in the spinal fluid. Physical manifestations include jaundice, enlarged liver, spleen, and lymph glands with cardiomegaly and valvular murmurs. Inheritance is autosomal intermediate.
