Children with short bowel syndrome (SBS) suffer from strikingly high rates of morbidity and mortality, due in part to their susceptibility to life-threatening infectious diseases. Few large, multisite studies have evaluated patient-specific factors associated with bacteremia in hospitalized children with and without SBS.
We conducted a case-control study to examine the epidemiological associations between SBS and bloodstream infections (BSI) in hospitalized children. Pediatric BSI cases and controls were selected from a prospective cohort study conducted at 3 New York City hospitals.
Among 40 723 hospital admissions of 30 179 children, 1047 diagnoses of BSI were identified. A total of 64 children had a diagnosis of SBS. BSI was identified frequently among hospitalizations for children admitted with SBS (n = 207/450, 46%) compared to hospitalizations for children without the condition (n = 840/40 273, 2.1%, P < .001). While this population represented only 0.2% of our overall cohort, it accounted for nearly 20% of all hospital admissions with BSI. Multivariable analysis identified 8 factors significantly associated with pediatric hospitalizations with BSI. These included a diagnosis of SBS (odds ratio [OR] 19.0), ages 1-5 years (OR 1.33), presence of a non-Broviac-Hickman central venous catheter (OR 6.36), immunosuppression (OR 0.53), kidney injury (OR 6.67), organ transplantation (OR 4.44), admission from a skilled nursing facility (OR 2.66), and cirrhosis (OR 7.23).
While several clinical characteristics are contributory to the risk of BSI in children, SBS remains the single strongest predictor. Further research into the mediators of this risk will be essential for the development of prevention strategies for this vulnerable population.
短肠综合征(SBS)患儿的发病率和死亡率极高,部分原因是他们易患危及生命的传染病。很少有大型多中心研究评估有无SBS的住院儿童中与菌血症相关的患者特异性因素。
我们进行了一项病例对照研究,以检查住院儿童中SBS与血流感染(BSI)之间的流行病学关联。儿科BSI病例和对照选自纽约市3家医院进行的一项前瞻性队列研究。
在30179名儿童的40723次住院中,确诊1047例BSI。共有64名儿童被诊断为SBS。与无该病症的儿童住院相比(n = 840/40273,2.1%,P < 0.001),患有SBS的儿童住院期间BSI的确诊率很高(n = 207/450,46%)。虽然这一群体仅占我们整个队列的0.2%,但几乎占所有BSI住院病例的20%。多变量分析确定了8个与儿科BSI住院显著相关的因素。这些因素包括SBS诊断(比值比[OR] 19.0)、1至5岁(OR 1.33)、存在非Broviac-Hickman中心静脉导管(OR 6.36)、免疫抑制(OR 0.53)、肾损伤(OR 6.67)、器官移植(OR 4.44)、来自专业护理机构的入院(OR 2.66)和肝硬化(OR 7.23)。
虽然有几个临床特征会增加儿童发生BSI的风险,但SBS仍然是最强的单一预测因素。进一步研究这种风险的介导因素对于为这一脆弱人群制定预防策略至关重要。
