髓细胞类白血病反应的存在与原发病有关,原发病好转,类白血病反应即随之消失。 Holland等认为髓细胞类白血病反应其外周血白细胞超过50×10~9/L或幼稚粒细胞(包括原始、早幼粒、中幼粒、晚幼粒细胞等)>5％。小儿粒细胞性类白血病反应最常见于脓毒血症、急性感染、大叶肺炎危象后、磺胺类药物治疗等。 某儿生后3～4天出现呕吐,发绀,诊断为葡萄球菌性肺炎、营养不良、脑病后遗症。血象:血红蛋白1 3g/L,红细胞4.7×10~(12)/L,血小板38.4×10~9/L,白细胞 The existence of myeloid leukemia reaction is related to the primary disease, the primary disease improves, the leukemia reaction disappears. According to Holland et al., Myeloid leukemia responds to> 5% peripheral blood leukocytes exceeding 50 × 10 ~ 9 / L or immature granulocytes (including primordial, promyelocytic, juvenile, late promyelocytic, etc). Pediatric leukemia leukemia most commonly seen in sepsis, acute infection, lobar pneumonia crisis, sulfa drugs and so on. Some children 3 to 4 days after birth, vomiting, cyanosis, diagnosis of staphylococcal pneumonia, malnutrition, brain sequelae. Blood: hemoglobin 1 3g / L, red blood cells 4.7 × 10 ~ (12) / L, platelets 38.4 × 10 ~ 9 / L, white blood cells
