    Background: Necrotizing enterocolitis (NEC) predominantly occurs in preterm infants (PT-NEC). In term neonates, NEC occurs more frequently when a congenital heart disease is present (CHDNEC). Our aim was to evaluate differences and similarities in disease characteristics of PT-NEC versus CHD-NEC.Methods: In this retrospective case-control study we identified all CHD infants who developed NEC Bell's stage &gt;= 2 in our center from 2004 to 2014. We randomly selected (1:2 ratio) PT-NEC infants from the same period. Biochemical and clinical variables were retrieved from patient files.Results: We found 18 CHD-NEC infants and selected 36 PT-NEC infants (gestational age 28.3 [25-35.6] weeks vs. 38.6 [31.7-40.7] weeks). Postnatal age at onset was significantly lower in CHD-NEC patients (4 [2-24] vs. 11 [4-41] days, p &lt;0.001). Lowest pH levels were lower (7.21 [7.01-7.47] vs. 7.27 [6.68-7.39], p = 0.02), and highest CRP levels were higher (112.5 mg/L [5.0-425.0] vs. 66.0 [52-189.0], p = 0.05) in PT-NEC vs. CHD-NEC. Anatomic localisation of the disease differed: the colon was significantly more often involved in CHD-NEC versus PT-NEC (86% vs. 33%, p = 0.03). Mortality caused by NEC was not different (22% vs. 11%, p = 0.47).Conclusion: While outcome of NEC in both groups is similar, the predominant NEC localisation differed between CHD-NEC and PT-NEC patients. This suggests that both variants of the disease have a different underlying pathophysiological mechanism that predisposes different intestinal regions to develop NEC.Type of Study: Retrospective Case-Control Study.

    BACKGROUND AND AIMS: Biliary atresia (BA) is a cholestatic, fibro-obliterative cholangiopathy of unknown etiology. BA is primarily treated by a surgical approach, i.e. the Kasai portoenterostomy (KPE), to obtain clearance of jaundice (COJ). The gut microbiota (GM) composition has been associated with the course of several cholestatic liver diseases. It is largely unknown, however, whether GM composition associates with the outcome of KPE. We compared the GM composition of BA patients and controls and assessed if GM composition before KPE was related to COJ after KPE. METHODS: We compared feces of term born BA patients before KPE and controls (patients undergoing inguinal hernia repair) by 16S rRNA sequencing. Composition and alpha diversity of the GM were compared between BA and controls before KPE and after KPE, between patients with COJ vs. without COJ (total serum bilirubin < or ≥ 20 μmol/L < 6mo post-KPE). RESULTS: Alpha diversity was comparable between BA (n = 12, age 1.6[1.3-1.8]mo) and controls (n = 6, age 2.0[1.4-2.1]mo; P = 0.22). Compared to controls, BA patients had lower abundances of Bifidobacteriaceae (β=-1.98, P < 0.001) and Lachnospiraceae (β=-1.84, P = 0.007), and higher abundances of Streptococcus (β=1.13, P = 0.003). The alpha diversity prior to KPE correlated negatively with COJ (R = -0.63, P = 0.03). Lower alpha diversity pre-KPE was associated with COJ [+] (βlogit = -0.64, P = 0.04). We observed greater abundances of genus Acinetobacter (β=1.27, P = 0.03) and family Clostridiaceae (β=1.45, P = 0.03) and lower abundances of the family Enterobacteriaceae, (genera Klebsiella (β=-1.21, P = 0.01), Salmonella (β=-1.57, P = 0.02)) in COJ [+] vs. COJ [-]. CONCLUSIONS: The gut microbiota of biliary atresia patients prior to Kasai portoenterostomy associates with outcome, clearance of jaundice, suggestive of predictive and mechanistic roles of the gut microbiota composition in bile homeostasis

    Introduction We aimed to assess health-related quality of life (HrQoL) in biliary atresia (BA) patients, based on original data and a literature review, and to determine factors associated with their HrQoL. Materials and Methods We reviewed available studies describing HrQoL in BA patients. We assessed HrQoL in Dutch BA patients (6-16 years) using the validated Child Health Questionnaire. We compared HrQoL scores in BA patients with healthy peers and with children who had undergone major surgery in infancy or children with chronic conditions. We determined the relationship between specific patient-related factors and HrQoL. Results Literature data indicated that HrQoL in children with BA is lower than in healthy peers. In Dutch BA patients (n = 38; age 10 ± 3 years), parent-proxy physical HrQoL (48 ± 11) was significantly lower compared with two reference groups of healthy peers (59 ± 4 and 56 ± 6, respectively, each p < 0.001), and lower than in children with attention deficit hyperactivity disorder (60 ± 5), asthma (54 ± 6), attending a cardiology clinic (52 ± n / r), congenital diaphragmatic hernia (53 ± 7) or D-transposition of the great arteries (54 ± 6; all p < 0.05). Psychosocial HrQoL (50 ± 9) was lower than in healthy peers (54 ± 6, p = 0.02, and 53 ± 6, p = 0.07) and children with asthma (54 ± 6, p = 0.02), and largely comparable to children with other chronic conditions. Parent-proxy physical HrQoL was adversely related to adverse medical event in the past year, special education, and motor impairments; psychosocial HrQoL was adversely related to behavioral problems. Conclusion Children with BA are at risk of impaired HrQoL. Special attention is warranted for children with adverse medical events and special education

    PURPOSE: To determine anxiety, stress, and quality of life (QoL) in parents of children who are diagnosed with biliary atresia (BA). METHODS: Parents of BA patients (0-3 years) completed validated questionnaires at three time points: at first hospitalization (T0); 1-2 months post diagnosis (T1); and 2-3 years post diagnosis (T2). Results are presented in medians (min-max). RESULTS: We included 52 parents (age 31 [24-51 y], 31 females) of 30 BA patients. In fathers, neither anxiety nor stress levels significantly differed from reference values. Mothers reported significantly higher anxiety levels compared to reference values (T0: 48 vs 35, p = 0.001; T1: 43 vs 35, p = 0.03; T2: 37 vs 35, p = 0.04), which significantly decreased over time (-23% between T0 and T2: p = 0.04). Stress in mothers was significantly higher at T1 than at T2 (+35%, p = 0.02), but was not significantly different from reference values at each time point (T0: 17 vs 14, p = 0.07; T1: 18 vs 14, p = 0.09; T2: 13 vs 14, p = 0.52).The overall QoL in mothers and fathers was rather unaffected. CONCLUSIONS: Particularly mothers of infants diagnosed with BA report high anxiety levels up to three years after diagnosis. The overall QoL of parents is rather unaffected after diagnosing BA in their child. LEVEL OF EVIDENCE: Level 2

    Objective: To assess long-term neurodevelopmental outcomes in school-aged children with biliary atresia. Study design: All Dutch children (6-12 years of age) diagnosed with biliary atresia were invited to participate in this study. We used validated neurodevelopmental tests to assess motor skills and cognition, and questionnaires to assess behavior. Scores were compared with the Dutch norm population, by means of 1-sample tests. Results are given as number and percentage or mean ± SD. Results: We included 46 children, with a median age of 11 years (range, 6-13 years); 36 children had undergone a liver transplantation (78%). Twelve children (26%) received special education (vs 2.4% in the norm population; P <.01). Motor outcomes were significantly affected compared with the norm population (P <.01), with 25% normal (vs 85%), 25% borderline (vs 10%), and 50% low scores (vs 5%). Total IQ was lower in patients with biliary atresia, compared with the norm population (91 ± 18 vs 100 ± 15; P <.01). There were no significant differences in test scores between children with native liver and after liver transplantation. Conclusions: School-aged children with biliary atresia show neurodevelopmental impairments compared with the norm population, especially in motor skills. Our data strongly warrant evaluation of neurodevelopmental intervention programs to assess whether long-term outcomes could be improved

    OBJECTIVE: To assess whether regional intestinal oxygen saturation (rintSO2) and regional cerebral oxygen saturation (rcSO2) measurements aid in estimating survival of preterm infants after surgery for NEC. SUMMARY OF BACKGROUND DATA: Predicting survival after surgery for NEC is difficult yet of the utmost importance for counseling parents. METHODS: We retrospectively studied prospectively collected data of preterm infants with surgical NEC who had available rintSO2 and rcSO2 values measured via near-infrared spectroscopy 0-24 hours preoperatively. We calculated mean rintSO2 and rcSO2 for 60-120 minutes for each infant. We analyzed whether preoperative rintSO2 and rcSO2 differed between survivors and non-survivors, determined cut-off points, and assessed the added value to clinical variables. RESULTS: We included 22 infants, median gestational age 26.9 weeks [interquartile range (IQR): 26.3-28.4], median birth weight 1088 g [IQR: 730-1178]. Eleven infants died postoperatively. Preoperative rintSO2, but not rcSO2, was higher in survivors than in non-survivors [median: 63% (IQR: 42-68) vs 29% (IQR: 21-43), P 53% survived, whereas all infants with rintSO2 <35% died. Median C-reactive protein [138 mg/L (IQR: 83-179) vs 73 mg/L (IQR: 12-98), P < 0.01), lactate [1.1 mmol/L (IQR: 1.0-1.6) vs 4.6 mmol/L (IQR: 2.8-8.0), P < 0.01], and fraction of inspired oxygen [25% (IQR: 21-31) vs 42% (IQR: 30-80), P < 0.01] differed between survivors and non-survivors. Only rintSO2 remained significant in the multiple regression model. CONCLUSIONS: Measuring rintSO2, but not rcSO2, seems of added value to clinical variables in estimating survival of preterm infants after surgery for NEC. This may help clinicians in deciding whether surgery is feasible and to better counsel parents about their infants' chances of survival

    Analysis of urinary oligosaccharides in lysosomal storage disorders by capillary high-performance anion-exchange chromatography–mass spectrometry

    Get PDF
    Many lysosomal storage diseases are characterized by an increased urinary excretion of glycoconjugates and oligosaccharides that are characteristic for the underlying enzymatic defect. Here, we have used capillary high-performance anion-exchange chromatography (HPAEC) hyphenated to mass spectrometry to analyze free oligosaccharides from urine samples of patients suffering from the lysosomal storage disorders fucosidosis, α-mannosidosis, GM1-gangliosidosis, GM2-gangliosidosis, and sialidosis. Glycan fingerprints were registered, and the patterns of accumulated oligosaccharides were found to reflect the specific blockages of the catabolic pathway. Our analytical approach allowed structural analysis of the excreted oligosaccharides and revealed several previously unpublished oligosaccharides. In conclusion, using online coupling of HPAEC with mass spectrometric detection, our study provides characteristic urinary oligosaccharide fingerprints with diagnostic potential for lysosomal storage disorders

    Surgical Outcome of Children with a Malignant Liver Tumour in The Netherlands:A Retrospective Consecutive Cohort Study

    Get PDF
    INTRODUCTION: Six to eight children are diagnosed with a malignant liver tumour yearly in the Netherlands. The majority of these tumours are hepatoblastoma (HB) and hepatocellular carcinoma (HCC), for which radical resection, often in combination with chemotherapy, is the only curative treatment option. We investigated the surgical outcome of children with a malignant liver tumour in a consecutive cohort in the Netherlands. METHODS: In this nationwide, retrospective observational study, all patients (age &lt; 18 years) diagnosed with a malignant liver tumour, who underwent partial liver resection or orthotopic liver transplantation (OLT) between January 2014 and April 2021, were included. Children with a malignant liver tumour who were not eligible for surgery were excluded from the analysis. Data regarding tumour characteristics, diagnostics, treatment, complications and survival were collected. Outcomes included major complications (Clavien-Dindo ≥ 3a) within 90 days and disease-free survival. The results of the HB group were compared to those of a historical HB cohort. RESULTS: Twenty-six children were analysed, of whom fourteen (54%) with HB (median age 21.5 months), ten (38%) with HCC (median age 140 months) and one with sarcoma and a CNSET. Thirteen children with HB (93%) and three children with HCC (30%) received neoadjuvant chemotherapy. Partial hepatic resection was possible in 19 patients (12 HB, 6 HCC, and 1 sarcoma), whilst 7 children required OLT (2 HB, 4 HCC, and 1 CNSET). Radical resection (R0, margin ≥ 1.0 mm) was obtained in 24 out of 26 patients, with recurrence only in the patient with CNSET. The mean follow-up was 39.7 months (HB 40 months, HCC 40 months). Major complications occurred in 9 out of 26 patients (35% in all, 4 of 14, 29% for HB). There was no 30- or 90-day mortality, with disease-free survival after surgery of 100% for HB and 80% for HCC, respectively. Results showed a tendency towards a better outcome compared to the historic cohort, but numbers were too small to reach significance. CONCLUSION: Survival after surgical treatment for malignant liver tumours in the Netherlands is excellent. Severe surgical complications arise in one-third of patients, but most resolve without long-term sequelae and have no impact on long-term survival
