Thrombocytopenia in Adults: Review Article

Abstract

Thrombocytopenia is the result of falling the number of platelet from 150,000/microL. There are three main reasons of thrombocytopenia, a-Decreasing of making platelet b-Increasing of destruction platelet c-Changing of distribution platelet. Pseudothrombocytopenia must be kept in mind too. Both hereditary and acquired reasons help thrombocytopenia have wide spreaded, but acquired causes are more common with increasing age. Thrombocytopenia separates three stages as numerical. Mild: 100,000 - 150,000/microL,Moderate: 50,000 - 100,000/microL. Severe: < 50,000/microL. However, thrombocytopenia is not usually detected clinically until the platelet count has fallen to levels below 100,000/microL. Severe thrombocytopenia, such as intracerebral and intra-abdominal bleeding may be life threatening. So diagnosing the treatment immediately can save the life. Transfusion of platelet may not need in all thrombocytopenias. Treatment of the underlying disease may be sufficient. The reason of thrombocytopenia can be temporary but also can be caused severe diseases. Causes of thrombocytopenia change development levels of countries, according to geographical distribution and application centers. In this review we emphasize common etiologies seen in adult patients with thrombocytopenia.
