Abstract

Ten patients with far-advanced Laennec's cirrhosis were studied for in vitro polymorphonuclear (PMN) chemotaxis and in vivo PMN delivery into modified skin windows. Random motility was similar for patient and control cells, but the patients' cells' mean chemotaxis to endotoxin-activated homologous serum was only 38% of control. The poor response was due to a serum inhibitor which reduced chemotactic activity of control serum by 75.6% but had no effect on chemotaxis to N-formyl-methionyl-leucyl-phenylalanine. The level of inhibitor activity in each patient did not correlate with the severity of liver dysfunction. In spite of the universal presence of the chemotactic factor inhibitor in all patients' sera, their in vivo PMN delivery into skin chambers was similar to controls. Thus, patients with alcoholic cirrhosis appear able to deliver PMNs normally in response to local tissue injury.

摘要

对10例晚期Laennec肝硬化患者进行了体外多形核白细胞(PMN)趋化性及体内PMN向改良皮肤窗递送情况的研究。患者细胞与对照细胞的随机运动相似,但患者细胞对内毒素激活的同源血清的平均趋化性仅为对照的38%。反应不佳是由于一种血清抑制剂,该抑制剂使对照血清的趋化活性降低了75.6%,但对N-甲酰甲硫氨酰亮氨酰苯丙氨酸的趋化性无影响。每位患者的抑制剂活性水平与肝功能障碍的严重程度无关。尽管所有患者血清中均普遍存在趋化因子抑制剂,但其体内PMN向皮肤腔室的递送情况与对照相似。因此,酒精性肝硬化患者似乎能够在局部组织损伤时正常递送PMN。
