What is the difference between thrombocythemia and thrombocytosis?
With primary thrombocythemia, a high platelet count may occur alone or with other blood cell disorders. This condition isn’t common. When another disease or condition causes a high platelet count, the term “thrombocytosis” is preferred. This condition often is called secondary or reactive thrombocytosis.
What is thrombocythemia?
Thrombocythemia is a disease in which your bone marrow makes too many platelets. Platelets are blood cell fragments that help with blood clotting. Having too many platelets makes it hard for your blood to clot normally. This can cause too much clotting, or not enough clotting.
Can essential thrombocythemia lead to leukemia?
Essential thrombocythemia patients develop acute myeloid leukemia (AML) at a rate of 1-4% during a median follow-up of 7-10 years. The risk increases with advanced age, anemia, platelet count ≥ 1000 × 10(9)/l, the presence of ≥ 2 somatic mutations and after the first decade of diagnosis.
How serious is myeloproliferative disorder?
Myeloproliferative disorders are slow acting, and don’t always cause life-threatening symptoms. The complications of these conditions, however, may be serious. Some complications include: Enlargement of the spleen and liver.
What is the life expectancy of someone with essential thrombocythemia?
The life expectancy of patients with essential thrombocytosis (primary thrombocythemia) is nearly that of the healthy population. Median survival is approximately 20 years. For patients younger than age 60 years, median survival is 33 years.
Why does splenectomy lead to thrombocytosis?
Mild thrombocytosis may be observed after a splenectomy due to the lack of sequestering and destruction of platelets that would normally be carried out by the spleen. In addition, the splenectomy may result in a slight increase in the production of platelets within the bone marrow.
What can cause thrombocytosis?
Inflammatory diseases that can cause thrombocytosis are rheumatoid arthritis, rheumatic polymyalgia, polyarteritis nodosa, inflammatory bowel disease, nephritis and liver cirrhosis. Typically, the degree of severity of the disease condition corresponds to that of thrombocytosis.
What are symptoms of thrombocytosis?
Arterial or venous blood clots
