Conditions related to defective production include hypoplastic or aplastic anemia, infiltration of bone marrow by malignant cells or myelofibrosis, viral infections, nutritional deficiency, and thrombocytopenic purpura. Increased destruction of platelets can be caused by infections, certain drugs, transfusion-related purpuras, idiopathic thrombocytopenic purpura, and disseminated intravascular coagulation
