Those that know the Hults family are aware of Harley’s diagnosis of the rare blood disorder, Hemopagocytic Lymphohisticytosis. It usually occurs in infants and children, but can appear in adults as well. Children usually inherit the disease.
If you have HLH, your body’s defense system, called your immune system, does not work normally. Certain white blood cells, histiocytes and lymphocytes, attack your other blood cells. These abnormal blood cells collect in your spleen and liver, causing these organs to enlarge.
