Neutrophilia (also called neutrophil leukocytosis or occasionally neutrocytosis) is leukocytosis of neutrophils, that is, a high number of neutrophil granulocytes in the blood. ==Causes== Neutrophil are the primary white blood cells that respond to a bacterial infection, so the most common cause of neutrophilia is a bacterial infection, especially pyogenic infections.〔Table 12-6 in: 8th edition.〕 Neutrophils are also increased in any acute inflammation, so will be raised after a heart attack,〔 other infarct or burns.〔 Some drugs, such as prednisone, have the same effect as cortisol and adrenaline (epinephrine), causing marginated neutrophils to enter the blood stream. Nervousness will very slightly raise the neutrophil count because of this effect. A neutrophilia might also be the result of a malignancy. Chronic myelogenous leukemia (CML or chronic myeloid leukaemia) is a disease where the blood cells proliferate out of control. These cells may be neutrophils. Neutrophilia can also be caused by appendicitis and splenectomy.〔(【引用サイトリンク】url=http://www.bloodandcancerclinic.com/neutrophilia.php )〕 Primary neutrophilia can additionally be a result of Leukocyte adhesion deficiency.〔https://www.orpha.net/data/patho/GB/uk-LeucocyteAdhesionDeficiency.pdf〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Neutrophilia」の詳細全文を読む スポンサード リンク
