Thrombocytopenia Overview

Thrombocyte is the medical term for platelet. Thrombocytopenia means a lower platelet count in the blood compared to the normal range. Thrombocytosis refers to a greater number of platelets compared to the normal range.

Platelets are important elements in the blood that are important for blood coagulation (clotting and prevention of bleeding). The normal platelet count ranges between 150,000 and 450,000 per microliter (one-millionth of a liter). Although the number of platelets is decreased, their function may remain intact in most cases of thrombocytopenia.

All blood cells (white cells, red cells, and platelets) are made in the bone marrow. Platelets are derived from larger cells in the bone marrow called megakaryocytes. Fragments of megakaryocytes are platelets, which are released into the bloodstream. Only about 2/3 of platelets released into the blood stream circulate in the blood, and the remaining 1/3 is typically captured by the spleen. The life cycle of platelets is usually about 7-10 days; therefore, the old ones are continuously being replaced by new ones.

Hepatitis is a general term that means inflammation of the liver. This inflammation can be caused by contagious diseases such as viral infections. Hepatitis can also be caused by exposure to alcohol, certain medications, chemicals, poisons, and other toxins, or by other diseases. Hepatitis C virus (HCV) is one of the many viruses that can cause inflammation of the liver.

Inflammation of the liver caused by infection with HCV is referred to as hepatitis C.

  • If the infection does not resolve, it becomes chronic (ongoing, long term) and can cause chronic liver disease, which can be serious or even fatal.
  • Approximately 75% to 85% of people infected with hepatitis C develop chronic hepatitis C. Many live normal lives, but some develop significant liver damage over several years.
  • If the disease progresses to liver failure (end stage liver disease), then liver transplant is the only treatment....
