再生障碍性贫血的预后极其严重,血小板减少引起出血是常见的死因,中性粒细胞减少后易患感染而导致死亡。本文报道的22例再生障碍性贫血患者有8例死于感染,5例的中性粒细胞少于100/立方毫米,单核细胞少于20/立方毫米。粒细胞与单核细胞绝对值之间有一定的联系。体外研究证明,单核细胞减少如同中性粒细胞减少一样,可使这些病人有严重感染的危险。 22例获得性再生障碍性贫血患者,均有骨髓增生低下,中性分叶核和杆状核粒细胞在1500/立方毫米以下,淋巴细胞超过1500。大多数患者血小板严重减少(少于50,000/立方毫米),仅1例正常。总的预 Aplastic anemia, the prognosis is extremely serious, thrombocytopenia bleeding is a common cause of death, neutropenia prone to infection and cause death. In this paper, 8 of 22 patients with aplastic anemia died of infection, 5 had less than 100 per cubic millimeter of neutrophils, and had less than 20 per cubic millimeter of monocytes. Granulocytes and monocytes have a certain relationship between the absolute value. In vitro studies have shown that monocytopenia, like neutropenia, can put these patients at a serious risk of infection. All 22 patients with acquired aplastic anemia had low myeloproliferation, with less than 1,500 cells / mm3 of neutral lobular nucleus and rod granulocytes and more than 1,500 lymphocytes. Most patients have a severe reduction of platelets (less than 50,000 / mm3) and only 1 patient is normal. Total pre
