Thrombocytopenia

thrombocytopenia

Definition of Thrombocytopenia

Thrombocytopenia is a condition in which there is a deficient number of circulating platelets.


Description of Thrombocytopenia

Thrombocytopenia may be congenital or acquired.

The acquired form is more common, especially among elderly. In either case, it usually results from decreased or defective production of platelets in the bone marrow (for example, in leukemia, aplastic anemia and with toxicity from certain drugs), increased destruction outside the marrow caused by an underlying disorder (such as cirrhosis of the liver, disseminated intravascular coagulation and severe infection) or dilution of platelets.

Less commonly, thrombocytopenia results from increased sequestration of platelets in the spleen.

Causes and Risk Factors of Thrombocytopenia

Acquired thrombocytopenia may result from the use of certain drugs, such as quinine, quinidine, rifampin, heparin, nonsteroidal anti-inflammatory agents, histamine blockers, most chemotherapeutic agents, allopurinol and alcohol.

Impaired production of platelets usually occurs when stem cells are injured or prevent their proliferation in bone marrow. Thrombocytopenia may be accompanied by varying degrees of anemia (low red blood cells) and leukopenia (low white blood cells). Diagnosis of a platelet production defect is established by examination of a bone marrow aspirate or biopsy.

The most common causes of decreased platelet production are marrow aplasia (when the marrow is not developing naturally), fibrosis (an abnormal formation) or infiltration with malignant cells.

Since one-third of the platelet mass is normally sequestered in the spleen, a splenectomy may increase the platelet count by 30 percent. In contrast, when the spleen enlarges, the fraction of sequestered platelets increases, lowering the platelet count. The most common causes of splenomegaly (enlarged spleen) are portal hypertension secondary to liver disease and splenic infiltration with tumor cells, or with macrophages in storage disorders (like Gaucher's disease).

Many common drugs can cause thrombocytopenia. Many chemotherapeutic agents are cytotoxic and depress megakaryocyte production. Ingestion of large quantities of alcohol has a similar marrow-depressing effect leading to transient thrombocytopenia. The syndrome is particularly common in binge drinkers.

Thiazide diuretics, which are commonly used to treat hypertension or congestive heart failure, can produce mild thrombocytopenia which may persist for several months after the drug is discontinued.

The best proof of a drug-induced etiology is a prompt rise in the platelet count when the suspected drug is discontinued. Most people recover within seven to 10 days and do not require therapy.

Thrombocytopenia may also occur transiently after a viral infection (such as Epstein-Barr) or infectious mononucleosis. Another form of thrombocytopenia is idiopathic thrombocytopenic purpura (ITP), an autoimmune disorder. Finally, there is thrombotic thrombocytopenic purpura (TTP), which is an uncommon disorder associated with anemia. Both ITP and TTP typically occur in adults, ages 20 through 50
