Bacterial infection in early period after liver transplant (LT) is the main cause of morbidity and mortality; however, data on children is limited.
To investigate the frequency, characteristics, and the associated factors of bacterial infection during hospitalization after LT, we prospectively enrolled all consecutive children with LT for a one-year, case-control study at the unique referral center of pediatric LT in Iran.
Eighty-five events of bacterial infection were detected among 51 out of 94 LT recipients (54.3%) (infection group). Forty-three patients without bacterial infection constituted the control group. The frequency of bacterial infection based on the 51 microbiologically documented events was 31.9% (30 out of 94 patients). Major site of bacterial isolation were abdomen (43.6%). The following variables were associated with bacterial infection in univariate analysis: younger age (5.6 vs 8.9 years old), longer duration of JP Drain (13.4 vs 6.3 days), central venous catheter (14.6 vs 7.6 days), and Foley catheter insertion (7.3 vs 4.5 days), reoperation (57% vs 12% of patients), mean frequency of reoperation (1.1 vs 0.1 times), and intensive care unit stay (12.1 vs 6.5 days). In multivariate analysis, only longer hospital stay after transplant (23.6 vs 10.9 days) was independently associated with bacterial infection. All ten deaths occurred within the infection group and half of which directly caused by infection.
These infections were associated with longer hospital stay and higher mortality rate. Conducting further studies with larger sample size and investigating more effective prophylactic measures should be considered in future studies.
肝移植(LT)术后早期的细菌感染是发病和死亡的主要原因;然而,关于儿童的数据有限。
为了调查LT术后住院期间细菌感染的频率、特征及相关因素,我们在伊朗唯一的小儿肝移植转诊中心对所有连续接受LT的儿童进行了为期一年的病例对照研究。
在94例LT受者中的51例(54.3%)(感染组)中检测到85次细菌感染事件。43例无细菌感染的患者构成对照组。基于51次微生物学记录事件的细菌感染频率为31.9%(94例患者中的30例)。细菌分离的主要部位是腹部(43.6%)。单因素分析中,以下变量与细菌感染相关:年龄较小(5.6岁对8.9岁)、腹腔引流管留置时间较长(13.4天对6.3天)、中心静脉导管留置时间较长(14.6天对7.6天)、留置导尿管时间较长(7.3天对4.5天)、再次手术(患者比例为57%对12%)、再次手术平均次数(1.1次对0.1次)以及重症监护病房住院时间(12.1天对6.5天)。多因素分析中,仅移植后住院时间较长(23.6天对10.9天)与细菌感染独立相关。所有10例死亡均发生在感染组,其中一半直接由感染导致。
这些感染与住院时间延长和死亡率升高相关。未来研究应考虑进行更大样本量的进一步研究并探索更有效的预防措施。
