A 14 year old boy with CGD of childhood received HLA-matched granulocyte transfusions in the therapy of an intramural abscess of the ileum. Donor granulocyte survival after transfusion was determined with the endotoxin-stimulated NBT test as well as an assay of chemiluminescence employing whole blood. The presence of circulating donor PMNs after transfusion was documented by both techniques. The half-life of donor cells in the first 5 hr following transfusion was approximately 1.4 hr with both techniques. The greatest number of transfused cells was detected by both methods in the patient's blood immediately after the completion of the transfusion. At this time 22.7% of the expected increment in donor PMN concentration was detected by the NBT test, and 13.8% of the expected increment was detected by chemiluminescence assay. Both techniques allow studies of posttransfusion granulocyte kinetics in CGD because of the basic underlying metabolic abnormality of recipient but not donor cells. The chemiluminescence assay may also be adaptable to use in neutropenic patients receiving PMN transfusions.
一名患有儿童慢性肉芽肿病(CGD)的14岁男孩在治疗回肠壁内脓肿时接受了 HLA 匹配的粒细胞输注。通过内毒素刺激的硝基四氮唑蓝(NBT)试验以及全血化学发光测定法来确定输血后供体粒细胞的存活情况。两种技术均证实输血后循环中有供体多形核中性粒细胞(PMN)存在。两种技术测得输血后最初5小时内供体细胞的半衰期约为1.4小时。输血完成后立即在患者血液中通过两种方法均检测到了最多数量的输注细胞。此时,通过NBT试验检测到供体PMN浓度预期增量的22.7%,通过化学发光测定法检测到预期增量的13.8%。由于受者而非供体细胞存在基本的潜在代谢异常,这两种技术都可用于研究CGD患者输血后粒细胞动力学。化学发光测定法也可能适用于接受PMN输血的中性粒细胞减少患者。
