Chronic Eosinophilic Leukemia

Eosinophilic leukemia belongs to a group of diseases called myeloproliferative disorders in which the bone marrow produces too many red blood cells, white blood cells, or platelets. Sometimes the body will make too many of more than one type of blood cell, but usually one type of blood cell is affected more than the others are. Chronic eosinophilic leukemia, formerly known as hypereosinophilic syndrome, is a disease marked by an abnormally high number of eosinophils. The body's white blood cells combat foreign intruders, such as viruses and bacteria. However, in chronic leukemia, the cells in the bone marrow that should develop into white blood cells multiply uncontrollably. These blood cells do not function properly, jeopardizing the production of normal blood cells. Among other consequences, this makes patients more susceptible to infections. In dogs and cats the disease is rare. The signs of eosinophilic leukemia usually include diarrhea and vomiting. Affected animals usually die within 6 months after the diagnosis, but chemotherapy may prolong survival.
