Reliable venous access is prerequisite for patients receiving long-term parenteral nutrition (PN). However, central venous catheters (CVCs) are an important risk factor for the development of potentially lethal complications, including catheter related bloodstream infection (CRBSI). We have retrospectively assessed the incidence of CRBSIs in children on long-term PN who were treated at the Children's Hospital Zagreb from January 2011 until January 2019 and the cost effectiveness of the use of taurolidine line locks in children at home PN (HPN). During this period 48 children received long-term PN and 24 children were discharged to HPN. The rate of CRBSI 1.15/1000 catheter days in total; 2.35/1000 days in the hospital and 0.48/1000 days at home. If taurolidine line lock was used every day of PN for children on HPN total costs would exceed existing CRBSI treatment costs more than 5 times.
可靠的静脉通路是接受长期肠外营养(PN)的患者的先决条件。然而,中心静脉导管(CVCs)是潜在致命并发症(包括导管相关性血流感染(CRBSI))发生的重要危险因素。我们回顾性评估了2011年1月至2019年1月在萨格勒布儿童医院接受长期PN治疗的儿童crbsi的发生率,以及在家庭PN (HPN)儿童中使用牛罗列丁线锁的成本效益。在此期间,48名儿童接受长期PN治疗,24名儿童出院至HPN治疗。CRBSI总发生率1.15/1000导管d;2.35/1000天在医院,0.48/1000天在家。如果对HPN患儿每日PN使用牛罗列丁线锁,总费用将超过现有CRBSI治疗费用的5倍以上。

Palm Oil and Beta-Palmitate in Infant Formula. 婴儿配方奶粉中的棕榈油和-棕榈酸酯。

T o the Editor: The position paper by ESPGHAN on palm oil (PO) and beta-palmitate in infant formula (1) shows undisputed biochemical and physiological basis for the negative nutrient absorption effect of palmitic acid from plant-based PO versus that from human or animal fat; and negative clinical effects in animal and tissue models. Use of PO in infant formula results in impaired fat and calcium absorption (2,3), lower growth measurements (4), and bone mass (5). There is uncertainty whether the negative effect on growth and bone accretion persists (1) because 1 cross-sectional follow-up study lacks control for multiple confounders of growth and bone mineralization and a longitudinal follow-up study had only 28% of the original cohort. In an era of evidence-based medicine, it seems prudent to recommend caution with the addition of PO in infant formula, given the multiple potential negative biochemical, physiological, and clinical effects of PO and lack of demonstrated benefits from PO. During infancy, there is a gain of 25 to 30 cm in length and tripling of the bone mass, an amount comparable to the peak bone accretion during adolescence on an annualized basis (6). Since the achievement of optimal peak bone mass throughout childhood and young adulthood is a cornerstone in the prevention of osteoporosis (7), and no guaranteed reversal of the negative effects of PO, it seems prudent to avoid adding PO to infant formula.
致编辑:ESPGHAN关于婴儿配方奶粉中棕榈油(PO)和-棕榈酸酯的立场文件(1)显示了无可争议的生化和生理学基础,即来自植物性PO的棕榈酸与来自人类或动物脂肪的棕榈酸相比具有负营养吸收效应;在动物和组织模型中有负面的临床效应。在婴儿配方奶粉中使用PO会导致脂肪和钙吸收受损(2,3),生长测量值降低(4)和骨量(5)。由于一项横断面随访研究缺乏对生长和骨矿化的多个混杂因素的控制,并且一项纵向随访研究只有28%的原始队列,因此不确定对生长和骨增生的负面影响是否会持续存在(1)。在循证医学的时代,考虑到PO的多种潜在的负面生化、生理和临床效应,以及缺乏证明PO的益处,建议在婴儿配方奶粉中谨慎添加PO似乎是明智的。在婴儿期,婴儿的长度会增加25到30厘米,骨量会增加三倍,这相当于青少年时期每年的骨质增加高峰(6)。由于在整个儿童期和青年期达到最佳骨量峰值是预防骨质疏松症的基石(7),并不能保证PO的负面影响会逆转,因此避免将PO添加到婴儿配方奶粉中似乎是明智的。

OBJECTIVESIn case of hypertriglyceridemia (HiTG) during parenteral nutrition (PN), the 2018 ESPGHAN guidelines recommend an intravenous (IV) lipid titration, but its consequences in small preterm infants are largely unknown. We compared macronutrient and energy intakes, growth, diseases associated with prematurity and neurodevelopment in small preterm infants on PN who developed (cases) or did not develop HiTG (controls, CNTR).METHODSWe retrospectively reviewed data of preterm infants with a birth weight (BW) <1250 g consecutively admitted to our NICU (2004-2016) who received routine PN. HiTG infants were defined by at least one triglyceride (TG) measurement >250 mg/dL during the first 10 days of life (DOL). Patients with and without HiTG were match-paired for BW and gestational age (GA).RESULTS658 infants were analysed and 196 (30%) had HiTG. 136 HiTG patients were matched with 136 CNTR. In the first 10 DOL, IV lipid, non-protein energy (NPE) and total energy intakes, but not IV amino acids (AA) and carbohydrates (CHO), were significantly lower in HiTG infants. We found no differences between groups in diseases associated with prematurity. Anthropometry at 36 weeks (W), anthropometry at 2-year (Y) corrected age (CA), and neurodevelopment at 2Y CA were not different.CONCLUSIONSGrowth, diseases associated with prematurity and neurodevelopment at 2Y CA in HiTG infants were similar to CNTR. This occurred despite a statistically significant albeit small reduction in IV lipid and NPE intakes due to a strict TG monitoring and IV lipid titration at TG levels >250 mg/dL.
目的:在肠外营养(PN)期间出现高甘油三酯血症(HiTG)的情况下,2018年ESPGHAN指南建议静脉(IV)脂质滴定,但其对小早产儿的影响在很大程度上是未知的。我们比较了发生hig(病例)或未发生hig(对照组,CNTR)的PN小早产儿的宏量营养素和能量摄入、生长、与早产和神经发育相关的疾病。方法回顾性分析出生体重(BW)为250 mg/dL的早产儿出生后10天的资料。有和没有HiTG的患者的体重和胎龄(GA)配对。结果658例患儿中有196例(30%)发生HiTG。136例HiTG患者与136例CNTR配对。在前10个DOL中,HiTG婴儿的IV脂质、非蛋白能量(NPE)和总能量摄入量显著降低,但IV氨基酸(AA)和碳水化合物(CHO)的摄入量未见降低。我们发现两组之间与早产相关的疾病没有差异。36周时的人体测量(W), 2岁时的人体测量(Y)校正年龄(CA)和2岁时的神经发育没有差异。结论HiTG婴儿2岁CA时的生长、早产相关疾病和神经发育与CNTR相似。尽管由于严格的TG监测和TG水平> 250mg /dL时的IV脂质滴定,IV脂质和NPE摄入量略有减少,但这一现象仍有统计学意义。

OBJECTIVESChildren with Crohn's disease may present with malnutrition and linear growth impairment which can be secondary to insufficient caloric intake, chronic inflammation, malabsorption, and suppression of growth-promoting hormones. We evaluated clinical, serologic, and genetic data to determine risk factors for impaired anthropometrics in Crohn's disease at diagnosis.METHODSOur study evaluated 772 children newly diagnosed with Crohn's disease, inflammatory phenotype, enrolled in the RISK Stratification Project to determine the factors associated with anthropometric impairment. Data were collected on demographics, growth parameters, disease location, serologic and immunologic markers, and disease severity. We performed a genome-wide association study of genetic polymorphisms associated with inflammatory bowel disease. Regression analysis determined associations between anthropometrics and clinical, serologic, and genetic variables.RESULTSThere were 59 (7%) children with height z-score <-2, 126 (14%) with a weight z-score <-2, and 156 (17%) with a BMI z-score <-2. Linear growth impairment was associated with hypoalbuminemia (p = 0.0052), elevated granulocyte-macrophage colony stimulating factor auto-antibodies (GM-CSF Ab) (p = 0.0110), and elevated CBir antibodies against flagellin (p = 0.0117). Poor weight gain was associated with female gender (p = 0.0401), hypoalbuminemia (p = 0.0162), and thrombocytosis (p = 0.0081). Malnutrition was associated with hypoalbuminemia (p = 0.0061) and thrombocytosis (p = 0.0011). Children with moderate or severe disease had lower weight (p = 0.02 and p = 1.16×10, respectively) and BMI z-scores (p = 2.7 × 10 and p = 1.01 × 10, respectively) than children with quiescent and mild disease. There was no association between age of diagnosis, Tanner stage, or disease location and having impaired anthropometrics. There was no genome-wide association between the genetic polymorphisms and the serologic variables and anthropometric measurements.CONCLUSIONSThis is the largest study evaluating growth in treatment-naïve children with Crohn's disease, inflammatory phenotype. It is the first study to use genome-wide sequencing to assess for genetic determinants of growth impairment. GM-CSF auto-antibodies and CBir antibodies are more likely to be elevated in children with growth impairment. Future investigations should evaluate the relationship between genetic polymorphisms, pathologic immune responses, and the biological pathways regulating growth.
克罗恩病患儿可能表现为营养不良和线性生长障碍,这可能是继发于热量摄入不足、慢性炎症、吸收不良和促生长激素抑制。我们评估了临床、血清学和遗传数据,以确定克罗恩病诊断时人体测量受损的危险因素。方法一项研究评估了772名新诊断为克罗恩病的儿童,炎症表型,纳入风险分层项目,以确定与人体测量功能障碍相关的因素。收集了人口统计学、生长参数、疾病部位、血清学和免疫标志物以及疾病严重程度的数据。我们进行了一项与炎症性肠病相关的遗传多态性全基因组关联研究。回归分析确定了人体测量学与临床、血清学和遗传变量之间的关联。结果身高z-score <-2者59例(7%),体重z-score <-2者126例(14%),BMI z-score <-2者156例(17%)。线性生长障碍与低白蛋白血症(p = 0.0052)、粒细胞-巨噬细胞集落刺激因子自身抗体(GM-CSF Ab)升高(p = 0.0110)和鞭毛蛋白CBir抗体升高(p = 0.0117)相关。体重增加不佳与女性(p = 0.0401)、低白蛋白血症(p = 0.0162)和血小板增多(p = 0.0081)有关。营养不良与低白蛋白血症(p = 0.0061)和血小板增多(p = 0.0011)相关。中度和重度疾病患儿的体重(p = 0.02, p = 1.16×10)和BMI z-score (p = 2.7 ×10, p = 1.01 ×10)均低于静止和轻度疾病患儿。诊断年龄、坦纳分期或疾病部位与人体测量受损之间没有关联。遗传多态性与血清学变量和人体测量值之间没有全基因组关联。结论:这是评估treatment-naïve克罗恩病儿童生长炎症表型的最大研究。这是第一个使用全基因组测序来评估生长障碍的遗传决定因素的研究。生长障碍儿童的GM-CSF自身抗体和cir抗体更可能升高。未来的研究应评估遗传多态性、病理性免疫反应和调节生长的生物学途径之间的关系。

Intestinal Wall Texture Analysis: Finding Fibrosis in Pediatric Patients with Crohn Disease. 肠壁结构分析:发现克罗恩病儿童患者的纤维化。

n this issue’s article, ‘‘Texture analysis of magnetic resonance enterography contrast enhancement can detect fibrosis in Crohn I disease strictures,’’ Tabari and co-workers demonstrated that a computer had greater diagnostic accuracy than a human radiologist (1). Using histology as the gold standard for fibrosis, the computer distinguished no fibrosis and mild fibrosis from moderate-to-severe fibrosis with an impressive area under the curve (AUC) of 0.995. To appreciate the significance of this article and that AUC, it will be helpful to review how far imaging has advanced in the 87 years since Dr Burrill Crohn’s seminal paper. In patients diagnosed with Crohn disease, almost half will develop a fibrotic stricture within 10 years of first receiving their diagnosis, often requiring surgical resection (2). The gold standard for diagnosing fibrosis is the deposition of collagen, detected histologically from full-thickness bowel resection. Due to the submucosal and subserosal location of the collagen deposition, fibrosis may be difficult to appreciate by endoscopic visualization or partial-thickness endoscopic biopsy. By imaging, a fibrotic stricture classically demonstrates 3 anatomic features: luminal narrowing, wall thickening, and prestenotic dilation (3). However, these 3 anatomic features alone are late features and are nonspecific, as active inflammation without fibrosis can have a similar appearance. In Crohn’s original 1932 article, he acknowledged the promise and limitations of anatomic imaging: ‘‘The barium meal, however, when carefully interpreted, gives definite positive findings. ... though only in the late or stenotic stages is the delay striking. The midler degrees of stasis and puddling in the ileal loops may easily be overlooked by any but a careful roentgenologist’’(4). It would be another 50 years before cross-sectional imaging (including computed tomography, magnetic resonance imaging ‘‘MRI,’’ and ultrasound) demonstrated diagnostic superiority compared with the traditional fluoroscopic ‘‘barium meal,’’ or what we would now call a ‘‘small bowel follow through’’(5).

在这期的文章中,“磁共振肠造影增强的纹理分析可以检测克罗恩病狭窄中的纤维化”,Tabari和同事证明了计算机比人类放射科医生具有更高的诊断准确性(1)。使用组织学作为纤维化的金标准,计算机区分无纤维化和轻度纤维化,从中度到重度纤维化,曲线下面积(AUC)为0.995。为了理解这篇文章和AUC的重要性,回顾一下自Burrill Crohn博士的开创性论文以来的87年里,成像技术取得了多大的进步将会有所帮助。在被诊断为克罗恩病的患者中,几乎一半会在首次确诊后的10年内发展为纤维化狭窄,通常需要手术切除(2)。诊断纤维化的金标准是胶原沉积,通过全层肠切除术在组织学上检测到。由于胶原沉积位于粘膜下和浆膜下,纤维化可能难以通过内镜可视化或部分厚度内镜活检来判断。通过影像学检查,纤维化狭窄典型地表现为3个解剖特征:管腔狭窄、管壁增厚和狭窄扩张(3)。然而,这3个解剖特征单独为晚期特征且非特异性,因为无纤维化的活动性炎症可能具有类似的外观。在克罗恩1932年的原始文章中,他承认了解剖成像的前景和局限性:“然而,当仔细解释钡餐时,给出了明确的积极结果. ...虽然只有在晚期或狭窄阶段才会出现明显的延迟。除了细心的x线医生外,任何人都很容易忽视回肠袢中中等程度的瘀滞和淤积。”又过了50年,横断成像(包括计算机断层扫描、磁共振成像和超声波)才显示出与传统的透视“钡餐”或我们现在所说的“小肠跟随检查”相比的诊断优势。然而,解剖细节的改进只能使诊断的准确性提高到目前为止。什么

Using histology as the gold standard for fibrosis, the computer distinguished no fibrosis and mild fibrosis from moderate-to-severe fibrosis with an impressive area under the curve (AUC) of 0.995. To appreciate the significance of this article and that AUC, it will be helpful to review how far imaging has advanced in the 87 years since Dr Burrill Crohn’s seminal paper. In patients diagnosed with Crohn disease, almost half will develop a fibrotic stricture within 10 years of first receiving their diagnosis, often requiring surgical resection (2). The gold standard for diagnosing fibrosis is the deposition of collagen, detected histologically from full-thickness bowel resection. Due to the submucosal and subserosal location of the collagen deposition, fibrosis may be difficult to appreciate by endoscopic visualization or partial-thickness endoscopic biopsy. By imaging, a fibrotic stricture classically demonstrates 3 anatomic features: luminal narrowing, wall thickening, and prestenotic dilation (3). However, these 3 anatomic features alone are late features and are nonspecific, as active inflammation without fibrosis can have a similar appearance. In Crohn’s original 1932 article, he acknowledged the promise and limitations of anatomic imaging: ‘‘The barium meal, however, when carefully interpreted, gives definite positive findings. ... though only in the late or stenotic stages is the delay striking. The midler degrees of stasis and puddling in the ileal loops may easily be overlooked by any but a careful roentgenologist’’(4). It would be another 50 years before cross-sectional imaging (including computed tomography, magnetic resonance imaging ‘‘MRI,’’ and ultrasound) demonstrated diagnostic superiority compared with the traditional fluoroscopic ‘‘barium meal,’’ or what we would now call a ‘‘small bowel follow through’’(5). However, improvements in anatomic detail would only take diagnostic accuracy so far.

OBJECTIVEDefine chronic HBV phenotypes in a large, cohort of US and Canadian children utilizing recently published population-based upper limit of normal alanine aminotransferase levels (ULN ALT), compared to local laboratory ULN; identify relationships with host and viral factors.BACKGROUNDChronic hepatitis B virus (HBV) infection has been characterized by phases or phenotypes, possibly associated with prognosis and indications for therapy.METHODSBaseline enrollment data of children in the Hepatitis B Research Network were examined. Phenotype definitions were; inactive carrier: HBeAg negative with low HBV DNA and normal ALT levels; immune tolerant: HBeAg positive with high HBV DNA but normal ALT levels; or chronic hepatitis B: HBeAg-positive or -negative with high HBV DNA and abnormal ALT levels.RESULTS371 participants were analyzed of whom 274 were HBeAg-positive (74%). Younger participants were more likely be HBeAg-positive with higher HBV DNA levels. If local laboratory ULN ALT levels were used, 35% were assigned the immune tolerant phenotype, but if updated ULN were applied, only 12% could be so defined, and the remaining 82% would be considered to have chronic hepatitis B. Among HBeAg-negative participants, only 21 (22%) were defined as inactive carriers and 14 (14%) as HBeAg-negative chronic hepatitis B; the majority (61%) had abnormal ALT and low levels of HBV DNA, thus having an indeterminant phenotype. Increasing age was associated with smaller proportions of HBeAg-positive infection.CONCLUSIONSAmong children with chronic HBV infection living in North America, the immune tolerant phenotype is uncommon and HBeAg positivity decreases with age.
目的:利用最近公布的以人群为基础的正常丙氨酸转氨酶水平上限(ULN ALT)与当地实验室ULN的比较,确定美国和加拿大儿童的大型队列中的慢性HBV表型;确定与宿主和病毒因素的关系。背景:慢性乙型肝炎病毒(HBV)感染具有分期或表型特征,可能与预后和治疗指征有关。方法对乙型肝炎研究网络中儿童的基线入组数据进行检查。表型定义为;无活性携带者:HBeAg阴性,HBV DNA低,ALT水平正常;免疫耐受:HBeAg阳性,HBV DNA高,但ALT水平正常;或慢性乙型肝炎:hbeag阳性或阴性,HBV DNA高,ALT水平异常。结果共分析371例受试者,其中hbeag阳性274例(74%)。年轻的参与者更有可能是hbeag阳性,HBV DNA水平较高。如果使用当地实验室ULN ALT水平,35%的人被指定为免疫耐受表型,但如果应用更新的ULN,只有12%的人可以定义为免疫耐受表型,其余82%的人将被认为患有慢性乙型肝炎。在hbeag阴性参与者中,只有21人(22%)被定义为非活性携带者,14人(14%)被定义为hbeag阴性慢性乙型肝炎;大多数(61%)有异常的ALT和低水平的HBV DNA,因此具有不确定的表型。随着年龄的增长,hbeag阳性感染的比例越小。结论在北美地区的慢性HBV感染儿童中,免疫耐受表型不常见,HBeAg阳性随年龄增长而降低。

OBJECTIVESAdults with chronic pancreatitis (CP) have a high risk for developing pancreatogenic diabetes mellitus (DM), but little is known regarding potential risk factors for DM in children with acute recurrent pancreatitis (ARP) or CP. We compared demographic and clinical features of children with ARP or CP, with and without DM, in the INternational Study Group of Pediatric Pancreatitis: In Search of a CuRE (INSPPIRE) registry.METHODSWe reviewed the INSPPIRE database for the presence or absence of physician-diagnosed DM in 397 children, excluding those with total pancreatectomy with islet autotransplantation, enrolled from August 2012 to August 2017. Patient demographics, body mass index percentile, age at disease onset, disease risk factors, disease burden, and treatments were compared between children with DM (n = 24) and without DM (n = 373).RESULTS24 children (6.0% of the cohort) had a diagnosis of DM. Five of 13 tested were positive for beta cell autoantibodies. The DM group was 4.2 years (95% CI 3.0, 5.4) older at first episode of acute pancreatitis, and tended to more often have hypertriglyceridemia (odds ratio (OR) 5.21 (1.33, 17.05)), coexisting autoimmune disease (OR 3.94 (0.88, 13.65)) or pancreatic atrophy (OR 3.64 (1.13, 11.59)).CONCLUSIONSPancreatic atrophy may be more common among children with DM, suggesting more advanced exocrine disease. However, data in this exploratory cohort also suggest increased autoimmunity and hypertriglyceridemia in children with DM, suggesting that risk factors for Type 1 and Type 2 DM respectively may play a role in mediating DM development in children with pancreatitis.
目的:慢性胰腺炎(CP)成人发展为胰源性糖尿病(DM)的风险很高,但对于急性复发性胰腺炎(ARP)或CP儿童发生糖尿病的潜在危险因素知之甚少。我们比较了国际儿童胰腺炎研究小组(inspire)登记中伴有和不伴有糖尿病的ARP或CP儿童的人口学和临床特征。方法:我们回顾了2012年8月至2017年8月纳入的397名儿童中医生诊断的糖尿病的存在或不存在,不包括接受全胰腺切除术和胰岛自体移植的儿童。比较糖尿病患儿(n = 24)和非糖尿病患儿(n = 373)的患者人口统计学、体重指数百分位数、发病年龄、疾病危险因素、疾病负担和治疗方法。结果24名儿童(占队列的6.0%)被诊断为糖尿病,13名患者中有5名β细胞自身抗体阳性。糖尿病组在急性胰腺炎首次发作时年龄大4.2岁(95% CI 3.0, 5.4),并且更容易出现高甘油三酯血症(优势比(OR) 5.21(1.33, 17.05))、并存自身免疫性疾病(OR 3.94(0.88, 13.65))或胰腺萎缩(OR 3.64(1.13, 11.59))。结论胰腺萎缩可能在糖尿病患儿中更为常见,提示外分泌疾病更为晚期。然而,该探索性队列的数据还表明,糖尿病儿童自身免疫和高甘油三酯血症增加,表明1型和2型糖尿病的危险因素可能分别在介导胰腺炎儿童糖尿病的发展中发挥作用。
