BACKGROUND/AIMS: To date, no data is available about procalcitonin (PCT) levels and its relevance to morbidity and graft function in the early phase after pediatric liver transplantation (pLTx). The aim of this study was to analyse the prognostic relevance of early postoperative PCT elevations in pediatric liver recipients.
Thirty pediatric patients who underwent 32 liver transplantations were included into this observational single-center study.
Patients with high PCT levels on postoperative day (POD) 2 had higher International Normalized Ratio values on POD 5 (p<0.05) and suffered more often from primary graft non-function (p<0.05). They also had a longer stay in the pediatric intensive care unit (p<0.01) and on mechanical ventilation (p=0.001). There was no correlation between PCT elevation and systemic infection. However, PCT levels were correlated with peak serum lactate levels immediately after graft reperfusion and elevation of serum aminotransferases on POD 1 (r2=0.61, p<0.001).
High levels of PCT after pLTx are an early indicator of poor postoperative outcome and may reflect ischemia induced liver cell injury within the context of an ischemia- reperfusion injury.
背景/目的:迄今为止,尚无关于小儿肝移植(pLTx)术后早期降钙素原(PCT)水平及其与发病率和移植物功能相关性的数据。本研究的目的是分析小儿肝移植受者术后早期PCT升高的预后相关性。
本观察性单中心研究纳入了30例接受32次肝移植的小儿患者。
术后第2天(POD)PCT水平高的患者在POD 5时国际标准化比值更高(p<0.05),且原发性移植物无功能的发生率更高(p<0.05)。他们在儿科重症监护病房的住院时间也更长(p<0.01),机械通气时间也更长(p=0.001)。PCT升高与全身感染之间无相关性。然而,PCT水平与移植肝再灌注后即刻的血清乳酸峰值水平以及POD 1时血清转氨酶升高相关(r2=0.61,p<0.001)。
pLTx术后PCT水平升高是术后不良结局的早期指标,可能反映了缺血再灌注损伤背景下的缺血性肝细胞损伤。
