研究了8例接受美法仑和顺铂隔离热肝灌注的晚期肝脏恶性肿瘤患者的补体激活和过敏毒素(C3 a和C5 a)和末端C5 b-9补体复合物(TCC)的形成。在手术前、灌注开始前1 min、灌注开始后1、2和3 h以及手术后24 h采集用于补体变量(C1 β INH、C3、C4、C5、C3 a、C5 a和TCC)的血样。在灌注开始后1小时从灌注液中取样。在灌注过程中观察到补体的活化。记录了升高的C3 a和TCC的血浆浓度,并且在灌注液中发现了高水平的C3 a和TCC。体外试验表明,美法仑和顺铂可以激活补体。这种活化在37和42°C下发生,但在42°C下更明显。
Eight patients with advanced liver malignancy undergoing isolated hyperthermic liver perfusion with melphalan and cisplatin were studied with regard to complement activation and formation of anaphylatoxins (C3a and C5a) and terminal C5b‐9 complement complexes (TCCs). Blood samples for complement variables (C1INH, C3, C4, C5, C3a, C5a and TCCs) were taken before surgery, 1 min before the start of perfusion, 1, 2 and 3 h after the start of perfusion, and 24 h after operation. Samples were drawn from the perfusate 1 h after the start of perfusion. Activation of complement was observed during perfusion. Raised plasma concentrations of C3a and TCCs were recorded and high levels of C3a and TCCs were found in the perfusate. In vitro tests indicated that melphalan and cisplatin may activate complement. This activation occurred at 37 and 42°C but was more pronounced at 42°C.
