摘要
Low circulating protein C (PC) levels have been observed in sepsis, especially in patients with Neisseriae Meningitides infections. Poor clinical outcome and high limb amputation rates have been associated in infected patients with low circulating PC levels. Published studies using activated PC replacement therapy patients with sepsis have shown reduced mortality rates, however, its use has been associated with severe bleeding events. Paediatric sepsis studies using non-activated plasma-derived PC (Ceprotin (R)) are lacking. We present a retrospective study in children with sepsis who were treated with Ceprotin (R) focusing on amputation rate post treatment. Thirty subjects were identified. Median age at diagnosis was 2 years. Twenty-one (70%) were treated for Nesseria Meningitides and one (3%) for Streptococcus- A beta- haemolyticus, another 8 (26%) patients with malignancies were treated for neutopenic sepsis. Following Ceprotin (R) administration, a significant increase in leukocyte count (p - 0.004), neutrophil count (p - 0.001) and PC (pretreatment - 13%, posttreatment - 88.5%; p - 0.0001) was seen. Prothrombin time (pretreatment = 30.3 seconds, posttreatment = 16.5; p = 0.000) and activated partial thromboplastin time (pretreatment = 61.8 sec, postreatment = 42.6 sec; p = 0.000) were significantly reduced, while fibrinogen levels were significantly elevated (pretreatment = 1.9 g/dL, posttreatment= 4.4 g/dL; p= 0.000). The median time between admission to intensive care and Ceprotin r administration was 10 hrs. Limb amputation rate was reduced (16- 23% versus 30- 50% from previous studies) and there were no haemorrhagic events observed. This study demonstrates the safe administration of non- activated plasma- derived PC concentrate in patients with sepsis who are coagulopathic and it associated with a reduction in amputation rates.
