Safety and efficacy of a probiotic-containing infant formula supplemented with 2'-fucosyllactose: a double-blind randomized controlled trial.

BACKGROUND: Human milk oligosaccharides (HMOs) have important and diverse biological functions in early life. This study tested the safety and efficacy of a starter infant formula containing Limosilactobacillus (L.) reuteri DSM 17938 and supplemented with 2'-fucosyllactose (2'FL). METHODS: Healthy infants < 14 days old (n = 289) were randomly assigned to a bovine milk-based formula containing L. reuteri DSM 17938 at 1 × 107 CFU/g (control group; CG) or the same formula with added 1.0 g/L 2'FL (experimental group; EG) until 6 months of age. A non-randomized breastfed group served as reference (BF; n = 60). The primary endpoint was weight gain through 4 months of age in the formula-fed infants. Secondary endpoints included additional anthropometric measures, gastrointestinal tolerance, stooling characteristics, adverse events (AEs), fecal microbiota and metabolism, and gut immunity and health biomarkers in all feeding groups. RESULTS: Weight gain in EG was non-inferior to CG as shown by a mean difference [95% CI] of 0.26 [-1.26, 1.79] g/day with the lower bound of the 95% CI above the non-inferiority margin (-3 g/day). Anthropometric Z-scores, parent-reported stooling characteristics, gastrointestinal symptoms and associated behaviors, and AEs were comparable between formula groups. Redundancy analysis indicated that the microbiota composition in EG was different from CG at age 2 (p = 0.050) and 3 months (p = 0.052), approaching BF. Similarly, between sample phylogenetic distance (weighted UniFrac) for BF vs EG was smaller than for BF vs CG at 3-month age (p = 0.045). At age 1 month, Clostridioides difficile counts were significantly lower in EG than CG. Bifidobacterium relative abundance in EG tracked towards that in BF. Fecal biomarkers and metabolic profile were comparable between CG and EG. CONCLUSION: L. reuteri-containing infant formula with 2'FL supports age-appropriate growth, is well-tolerated and may play a role in shifting the gut microbial pattern towards that of breastfed infants. TRIAL REGISTRATION: The trial was registered on ClinicalTrials.gov ( NCT03090360 ) on 24/03/2017.

Belgian Consensus Recommendations to Prevent Vitamin K Deficiency Bleeding in the Term and Preterm Infant.

Neonatal vitamin K prophylaxis is essential to prevent vitamin K deficiency bleeding (VKDB) with a clear benefit compared to placebo. Various routes (intramuscular (IM), oral, intravenous (IV)) and dosing regimens were explored. A literature review was conducted to compare vitamin K regimens on VKDB incidence. Simultaneously, information on practices was collected from Belgian pediatric and neonatal departments. Based on the review and these practices, a consensus was developed and voted on by all co-authors and heads of pediatric departments. Today, practices vary. In line with literature, the advised prophylactic regimen is 1 or 2 mg IM vitamin K once at birth. In the case of parental refusal, healthcare providers should inform parents of the slightly inferior alternative (2 mg oral vitamin K at birth, followed by 1 or 2 mg oral weekly for 3 months when breastfed). We recommend 1 mg IM in preterm <32 weeks, and the same alternative in the case of parental refusal. When IM is perceived impossible in preterm <32 weeks, 0.5 mg IV once is recommended, with a single additional IM 1 mg dose when IV lipids are discontinued. This recommendation is a step towards harmonizing vitamin K prophylaxis in all newborns.

Linking Human Milk Oligosaccharides, Infant Fecal Community Types, and Later Risk To Require Antibiotics.

Human milk oligosaccharides (HMOs) may provide health benefits to infants partly by shaping the development of the early-life intestinal microbiota. In a randomized double-blinded controlled multicentric clinical trial, healthy term infants received either infant formula (control) or the same formula with two HMOs (2'-fucosyllactose and lacto-N-neotetraose; test) from enrollment (0 to 14 days) to 6 months. Then, all infants received the same follow-up formula without HMOs until 12 months of age. Breastfed infants (BF) served as a reference group. Stool microbiota at 3 and 12 months, analyzed by 16S rRNA gene sequencing, clustered into seven fecal community types (FCTs) with marked differences in total microbial abundances. Three of the four 12-month FCTs were likely precursors of the adult enterotypes. At 3 months, microbiota composition in the test group (n = 58) appeared closer to that of BF (n = 35) than control (n = 63) by microbiota alpha (within group) and beta (between groups) diversity analyses and distribution of FCTs. While bifidobacteriaceae dominated two FCTs, its abundance was significantly higher in one (FCT BiH for Bifidobacteriaceae at high abundance) than in the other (FCT Bi for Bifidobacteriaceae). HMO supplementation increased the number of infants with FCT BiH (predominant in BF) at the expense of FCT Bi (predominant in control). We explored the association of the FCTs with reported morbidities and medication use up to 12 months. Formula-fed infants with FCT BiH at 3 months were significantly less likely to require antibiotics during the first year than those with FCT Bi. Previously reported lower rates of infection-related medication use with HMOs may therefore be linked to gut microbiota community types. (This study has been registered at ClinicalTrials.gov under registration number NCT01715246.)IMPORTANCE Human milk is the sole and recommended nutrition for the newborn infant and contains one of the largest constituents of diverse oligosaccharides, dubbed human milk oligosaccharides (HMOs). Preclinical and clinical association studies indicate that HMOs have multiple physiological functions largely mediated through the establishment of the gut microbiome. Until recently, HMOs were not available to investigate their role in randomized controlled intervention trials. To our knowledge, this is the first report on the effects of 2 HMOs on establishing microbiota in newborn infants. We provide a detailed description of the microbiota changes observed upon feeding a formula with 2 HMOs in comparison to breastfed reference infants' microbiota. Then, we associate the microbiota to long-term health as assessed by prescribed antibiotic use.

Partially Hydrolysed Whey-Based Formulae with Reduced Protein Content Support Adequate Infant Growth and Are Well Tolerated: Results of a Randomised Controlled Trial in Healthy Term Infants.

The current study aimed to investigate growth, safety and tolerance of partially hydrolysed infant formulae in healthy full-term infants. Fully formula-fed infants were randomised ≤14 days of age to receive a partially hydrolysed whey formula with 2.27 g protein/100 kcal (pHF2.27) or the same formula with 1.8 g or 2.0 g protein/100 kcal (pHF1.8 and pHF2.0) until 4 months of age. The primary outcome was equivalence in daily weight gain within margins of ± 3 g/day; comparison with WHO Child Growth Standards; gastrointestinal tolerance parameters and number of (serious) adverse events were secondary outcomes. A total of 207 infants were randomised, and 61 (pHF1.8), 46 (pHF2.0) and 48 (pHF2.27) infants completed the study per protocol. Equivalence in daily weight gain was demonstrated for the comparison of pHF1.8 and pHF2.27, i.e., the estimated difference was -1.12 g/day (90% CI: [-2.72; 0.47]) but was inconclusive for the comparisons of pHF2.0 and pHF2.27 with a difference of -2.52 g/day (90% CI: [-4.23; -0.81]). All groups showed adequate infant growth in comparison with the World Health Organization (WHO) Child Growth Standards. To conclude, the evaluated partially hydrolysed formulae varying in protein content support adequate growth and are safe and well tolerated in healthy infants.

Long-term Outcomes with Anti-TNF Therapy and Accelerated Step-up in the Prospective Pediatric Belgian Crohn's Disease Registry (BELCRO).

BACKGROUND: Accelerated step-up or anti-tumor necrosis factor (TNF) before first remission is currently not recommended in pediatric Crohn's disease. METHODS: Five-year follow-up data from a prospective observational cohort of children diagnosed with Crohn's disease in Belgium were analyzed. Disease severity was scored as inactive, mild, or moderate to severe. Remission or inactive disease was defined as sustained if lasting ≥2 years. Univariate analyses were performed between anti-TNF-exposed versus naive patients and anti-TNF before versus after first remission and correlations assessed with primary outcomes average disease severity and sustained remission. RESULTS: A total of 91 patients (median [IQR] age 12.7 [10.9-14.8] yrs, 53% male) were included. Disease location was 12% L1, 23% L2, and 64% L3 with 76% upper gastrointestinal and 30% perianal involvement. Disease severity was 25% mild and 75% moderate to severe. Of 66 (73%) anti-TNF-exposed patients, 34 (52%) had accelerated step-up. Anti-TNF use was associated with age (13.1 [11.5-15.2] versus 11.8 [8.7-13.8] yrs; P < 0.05), L2 (29% versus 8%; P = 0.04), and average disease severity (1.7 [1.4-1.9] versus 1.4 [1.3-1.6]; P < 0.001). Duration of anti-TNF correlated with average disease severity (r = 0.32, P = 0.002). Accelerated step-up was also associated with age (13.3 [12.1-15.9] versus 12.5 [10.2-14.1]; P = 0.02) and average disease severity (1.8 [1.6-1.9] versus 1.6 [1.3-1.8]; P = 0.002). Duration of sustained remission was similar in all patients, and no serious infections, cancer, or deaths were reported. CONCLUSIONS: Anti-TNF therapy and accelerated step-up in older patients with more severe disease leads to beneficial long-term outcomes.

Accuracy in Diagnosis of Celiac Disease Without Biopsies in Clinical Practice.

BACKGROUND & AIMS: The guidelines of the European Society of Pediatric Gastroenterology, Hepatology, and Nutrition allow for diagnosis of celiac disease without biopsies in children with symptoms and levels of immunoglobulin A against tissue-transglutaminase (TGA-IgA) 10-fold or more the upper limit of normal (ULN), confirmed by detection of endomysium antibodies (EMA) and positivity for HLA-DQ2/DQ8. We performed a large, international prospective study to validate this approach. METHODS: We collected data from consecutive pediatric patients (18 years or younger) on a gluten-containing diet who tested positive for TGA-IgA from November 2011 through May 2014, seen at 33 pediatric gastroenterology units in 21 countries. Local centers recorded symptoms; measurements of total IgA, TGA, and EMA; and histopathology findings from duodenal biopsies. Children were considered to have malabsorption if they had chronic diarrhea, weight loss (or insufficient gain), growth failure, or anemia. We directly compared central findings from 16 antibody tests (8 for TGA-IgA, 1 for TGA-IgG, 6 for IgG against deamidated gliadin peptides, and 1 for EMA, from 5 different manufacturers), 2 HLA-DQ2/DQ8 tests from 2 manufacturers, and histopathology findings from the reference pathologist. Final diagnoses were based on local and central results. If all local and central results were concordant for celiac disease, cases were classified as proven celiac disease. Patients with only a low level of TGA-IgA (threefold or less the ULN) but no other results indicating celiac disease were classified as no celiac disease. Central histo-morphometry analyses were performed on all other biopsies and cases were carefully reviewed in a blinded manner. Inconclusive cases were regarded as not having celiac disease for calculation of diagnostic accuracy. The primary aim was to determine whether the nonbiopsy approach identifies children with celiac disease with a positive predictive value (PPV) above 99% in clinical practice. Secondary aims included comparing performance of different serological tests and to determine whether the suggested criteria can be simplified. RESULTS: Of 803 children recruited for the study, 96 were excluded due to incomplete data, low level of IgA, or poor-quality biopsies. In the remaining 707 children (65.1% girls; median age, 6.2 years), 645 were diagnosed with celiac disease, 46 were found not to have celiac disease, and 16 had inconclusive results. Findings from local laboratories of TGA-IgA 10-fold or more the ULN, a positive result from the test for EMA, and any symptom identified children with celiac disease (n = 399) with a PPV of 99.75 (95% confidence interval [CI], 98.61-99.99); the PPV was 100.00 (95% CI, 98.68-100.00) when only malabsorption symptoms were used instead of any symptom (n = 278). Inclusion of HLA analyses did not increase accuracy. Findings from central laboratories differed greatly for patients with lower levels of antibodies, but when levels of TGA-IgA were 10-fold or more the ULN, PPVs ranged from 99.63 (95% CI, 98.67-99.96) to 100.00 (95% CI, 99.23-100.00). CONCLUSIONS: Children can be accurately diagnosed with celiac disease without biopsy analysis. Diagnosis based on level of TGA-IgA 10-fold or more the ULN, a positive result from the EMA tests in a second blood sample, and the presence of at least 1 symptom could avoid risks and costs of endoscopy for more than half the children with celiac disease worldwide. HLA analysis is not required for accurate diagnosis. Clinical Trial Registration no: DRKS00003555.

Randomised controlled trial demonstrates that fermented infant formula with short-chain galacto-oligosaccharides and long-chain fructo-oligosaccharides reduces the incidence of infantile colic.

AIM: We examined the effects on gastrointestinal (GI) tolerance of a novel infant formula that combined specific fermented formula (FERM) with short-chain galacto-oligosaccharides and long-chain fructo-oligosaccharides (scGOS/lcFOS), with a 9:1 ratio and concentration of 0.8 g/100 mL. METHODS: This prospective, double-blind, randomised, controlled trial comprised 432 healthy, term infants aged 0-28 days whose parents decided to not start, or discontinued, breastfeeding. Infant formula with scGOS/lcFOS+50%FERM, scGOS/lcFOS+15%FERM, 50%FERM and scGOS/lcFOS were tested. Parents completed standardised seven-day diaries on GI symptoms, crying, sleeping and stool characteristics each month until the infants were 17 weeks. RESULTS: All the formulas were well tolerated. At four weeks, the overall incidence of infantile colic was significantly lower (8%) with scGOS/lcFOS+50%FERM than scGOS/lcFOS (20%, p = 0.034) or 50%FERM (20%, p = 0.036). Longitudinal modelling showed that scGOS/lcFOS+50%FERM-fed infants also displayed a persistently lower daily crying duration and showed a consistent stool-softening effect than infants who received formula without scGOS/lcFOS. CONCLUSION: The combination of fermented formula with scGOS/lcFOS was well tolerated and showed a lower overall crying time, a lower incidence of infantile colic and a stool-softening effect in healthy term infants. These findings suggest for the first time that a specific infant formula has a preventive effect on infantile colic in formula-fed infants.

Effects of Infant Formula With Human Milk Oligosaccharides on Growth and Morbidity: A Randomized Multicenter Trial.

OBJECTIVES: The aim of the study was to evaluate the effects of infant formula supplemented with 2 human milk oligosaccharides (HMOs) on infant growth, tolerance, and morbidity. METHODS: Healthy infants, 0 to 14 days old, were randomized to an intact-protein, cow's milk-based infant formula (control, n = 87) or the same formula with 1.0 g/L 2'fucosyllactose (2'FL) and 0.5 g/L lacto-N-neotetraose (LNnT) (test, n = 88) from enrollment to 6 months; all infants received standard follow-up formula without HMOs from 6 to 12 months. Primary endpoint was weight gain through 4 months. Secondary endpoints included additional anthropometric measures, gastrointestinal tolerance, behavioral patterns, and morbidity through age 12 months. RESULTS: Weight gain was similar in both groups (mean difference [95% confidence interval] test vs control: -0.30 [-1.94, 1.34] g/day; lower bound of 95% confidence interval was above noninferiority margin [-3 g/day]). Digestive symptoms and behavioral patterns were similar between groups; exceptions included softer stool (P = 0.021) and fewer nighttime wake-ups (P = 0.036) in the test group at 2 months. Infants receiving test (vs control) had significantly fewer parental reports (P = 0.004-0.047) of bronchitis through 4 (2.3% vs 12.6%), 6 (6.8% vs 21.8%), and 12 months (10.2% vs 27.6%); lower respiratory tract infection (adverse event cluster) through 12 months (19.3% vs 34.5%); antipyretics use through 4 months (15.9% vs 29.9%); and antibiotics use through 6 (34.1% vs 49.4%) and 12 months (42.0% vs 60.9%). CONCLUSIONS: Infant formula with 2'FL and LNnT is safe, well-tolerated, and supports age-appropriate growth. Secondary outcome findings showing associations between consuming HMO-supplemented formula and lower parent-reported morbidity (particularly bronchitis) and medication use (antipyretics and antibiotics) warrant confirmation in future studies.

Proposal for An Algorithm for Screening for Undernutrition in Hospitalized Children.

The prevalence of disease-related undernutrition in hospitalized children has not decreased significantly in the last decades in Europe. A recent large multicentric European study reported a percentage of underweight children ranging across countries from 4.0% to 9.3%. Nutritional screening has been put forward as a strategy to detect and prevent undernutrition in hospitalized children. It allows timely implementation of adequate nutritional support and prevents further nutritional deterioration of hospitalized children. In this article, a hands-on practical guideline for the implementation of a nutritional care program in hospitalized children is provided. The difference between nutritional status (anthropometry with or without additional technical investigations) at admission and nutritional risk (the risk of the need for a nutritional intervention or the risk for nutritional deterioration during hospital stay) is the focus of this article. Based on the quality control circle principle of Deming, a nutritional care algorithm, with detailed instructions specific for the pediatric population was developed and implementation in daily practice is proposed. Further research is required to prove the applicability and the merit of this algorithm. It can, however, serve as a basis to provide European or even wider guidelines.

Paediatric Crohn Disease: Disease Activity and Growth in the BELCRO Cohort After 3 Years Follow-up.

OBJECTIVE: The Belgian registry for paediatric Crohn disease (BELCRO) cohort is a prospective, multicentre registry for newly diagnosed paediatric patients with Crohn disease (CD) (<18 years) recruited from 2008 to 2010 to identify predictive factors for disease activity and growth. METHODS: Data from the BELCRO database were evaluated at diagnosis, 24 and 36 months follow-up. RESULTS: At month 36 (M36), data were available on 84 of the 98 patients included at diagnosis. Disease activity evolved as follows: inactive 5% to 70%, mild 19% to 24%, and moderate to severe 76% to 6%. None of the variables such as age, sex, diagnostic delay, type of treatment, disease location, disease activity at diagnosis, and growth were associated with disease activity at M36. Paediatricians studied significantly less patients with active disease at M36 compared with adult physicians. Sixty percent of the patients had biologicals as part of their treatment at M36. Adult gastroenterologists initiated biologicals significantly earlier. They were the only factor determining biologicals' initiation, not disease location or disease severity at diagnosis. Median body mass index (BMI) z score evolved from -0.97 (range -5.5-2.1) to 0.11 (range -3.4-2) and median height z score from -0.15 (range -3.4-1.6) to 0.12 (range -2.3-2.3) at M36. None of the variables mentioned above influenced growth over time. CONCLUSIONS: Present treatment strategies lead to good disease control in the BELCRO cohort after 3 years. Logistic regression analysis did not show any influence of disease location or present treatment strategy on disease activity and growth, but patients under paediatric care had significantly less severe disease at M36.

More training and awareness are needed to improve the recognition of undernutrition in hospitalised children.

AIM: Reports suggest that 10% of hospitalised children in Europe are undernourished. We investigated whether nutritional screening tools (NST) were used in Belgian secondary-level hospitals, examined strategies for detecting undernutrition and identified barriers preventing the systematic management of undernutrition. METHODS: A nationwide questionnaire-based survey of paediatric departments in Belgian secondary-level hospitals was carried out from September 2013 to February 2014. Respondents were dived into French-speaking (Walloon + Brussels) and Dutch-speaking (Flemish) departments. RESULTS: We received replies from 71 of the 97 (73.2%) departments. Half of the departments - 39.5% Flemish speaking and 71.4% Walloon speaking - carried out nutritional screening. Undernutrition was identified by measuring weight and length or height (92.7% of cases), clinical appraisal (74.7%), mid-upper arm circumference and/or skin fold thickness (19.7%). There was no protocol for undernutrition in many Flemish (60.5%)- and Walloon (28.6%)-speaking departments. Reasons given for not screening were as follows: lack of training (46.9%), ignorance of NST (42.2%) and lack of time (29.7%). CONCLUSION: Half of the paediatric departments in Belgian secondary-level hospitals did not carry out nutritional screening, and differences in current practices and attitudes may be due to cultural and/or educational differences.

The course of anaemia in children and adolescents with Crohn's disease included in a prospective registry.

AIM: The aim of this study is to determine the prevalence and evolution of anaemia in prospectively followed children and adolescents diagnosed with Crohn's disease (CD). METHODS: The BELCRO registry (inclusion May 2008-April 2010), describing current clinical treatment practice of children diagnosed with CD, provided data on age, height, body mass index (BMI), paediatric Crohn's disease activity index (PCDAI), therapy and haemoglobin (Hb) at diagnosis 12 and 24 months follow-up. Anaemia was defined as Hb < -2 sd, while severe anaemia was defined as Hb < -4 sd. Patients were classified as child ≤13 and adolescent >13 years of age. RESULT: Ninety-six were included, 13 dropped out due to insufficient Hb data (37 females/46 males; median age 13.3 years, range 2.2-17.8 years). At diagnosis, the median Hb sd was -2.66 (-8.4; 1.07) and was correlated with the PCDAI (p = 0.013). At diagnosis, 51/83 (61%) were anaemic and all had active disease. Hb z-score significantly improved (p < 0.0001) but 26/68 (38%) remained anaemic at 12 months and 29/76 (38%) at 24 months of follow-up. The correlation to the PCDAI disappeared. At 24 months, children were more likely to be anaemic. There was no difference in iron dose nor duration of iron supplements between children and adolescents. Iron treatment was more readily given to patients presenting with anaemia. Hb did not differ between patients with (n = 28) or without iron supplements. Half of the patients with persisting anaemia were given iron supplements, of which, only three were given intravenously. CONCLUSION: Anaemia remains an important extra-intestinal manifestation of CD in children. Physicians, lacking optimal treatment strategies, undertreat their patients.

Nutritional status of children hospitalized for parapneumonic effusion.

BACKGROUND & AIMS: Among children hospitalized for pneumonia, those with parapneumonic effusion (PPE) are at particular risk for nutritional deterioration. This study aimed to 1) investigate the evolution of the nutritional status during hospitalization and at outpatient follow-up; 2) determine clinical risk factors for weight loss during hospitalization; 3) describe the nutritional interventions for these children. METHODS: Retrospective chart review (January '07 - September '12) of 56 children with pneumonia, complicated by PPE in two Belgian hospitals for data on body weight and height at admission (t0) and discharge (t1), and two weeks (t2) and one month (t3) after discharge. Length of hospitalization (LoS), length of stay in paediatric intensive care (LoSPICU) and maximal in-hospital weight loss (tmax) were calculated and nutritional interventions were recorded. RESULTS: The median (range) age was 3.5 (1.0-14.8) years. Weight or height was lacking in five (8.9%) children at t0 and in 28 (50%) at t1; 21.4% was weighed only once during hospitalization. At tmax, respectively 17/44 and 5/44 children lost ≥ 5% and ≥ 10% of their weight. Median (range) LoS and LoSPICU were 18.0 (10-41) and 4.0 (0-23) days. One-fourth received a nutritional intervention. Weight for height at admission (WFH(t0)) significantly predicted maximal weight loss (ß (95% CI) = -0.34 (-2.0--0.1); p = 0.03). At t2 and t3, 13/32 and 5/22 of the children with available follow-up data did not reach WFH(t0), whilst in 4/35 and 5/26 body weight remained ≥ 5% under the weight(t0). CONCLUSIONS: One-third of children with pneumonia complicated by PPE and monitored for weight and height, lost ≥ 5% of their body weight during hospitalization. One-fourth did not reach initial WFH one month after discharge. Those with a higher WFH at admission were at higher risk of weight loss. More attention for monitoring of weight loss and the nutritional policy during and after hospitalization is warranted.

Venous thrombosis in a child with ulcerative colitis in remission: a case report.

Over the past 70 years, an association between venous thromboembolism and inflammatory bowel disease has been described. We report on a thirteen year old boy with ulcerative colitis and venous thrombosis. Literature on incidence of venous thromboembolism in inflammatory bowel disease (IBD) is reviewed as well as the possible pathogenetic mechanisms of this 'hypercoagulable state': role of acquired risk factors, inflammation, coagulation abnormalities and platelets. Finally, treatment of IBD and thrombosis is discussed.

The STRONG(kids) nutritional screening tool in hospitalized children: a validation study.

OBJECTIVE: The STRONGkids is a nutritional screening tool for hospitalized children, which was found to predict a negative weight for height (WFH) standard deviation score (SDS) and a prolonged hospital length of stay (LOS) in a Dutch population of hospitalized children. This study aimed to test the ease of use and reproducibility of the STRONGkids, and to confirm its concurrent and prospective validity in a Belgian population of hospitalized children. METHODS: Reproducibility was tested in a cohort of 29 hospitalized children in a tertiary center and validity was tested in 368 children (105 hospitalized in a tertiary and 263 in three secondary hospitals) ages between 0.08 and 16.95 y (median 2.2 y). RESULTS: Substantial intrarater (κ = 0.66) and interrater (κ = 0.61) reliabilities were found between observations. STRONGkids scores correlated negatively with WFH SDS of the patients (ρ = -0.23; P < 0.01; odds ratio [OR], 2.47; 95% confidence interval [CI], 1.11-5.49; P < 0.05). It had a sensitivity and negative predictive value (NPV) of respectively 71.9% and 94.8% to identify acutely undernourished children. STRONGkids did not correlate with weight loss during hospitalization, but correlated with LOS (ρ = 0.25; OR 1.96; 95% CI, 1.25-3.07; both P < 0.01) and the set-up of a nutritional intervention during hospitalization (OR, 18.93; 95% CI, 4.48-80.00; P < 0.01). The sensitivity and NPV to predict a LOS ≥ 4 d were respectively 62.6% and 72%, and respectively 94.6% and 98.9% to predict a nutritional intervention. CONCLUSIONS: STRONGkids is an easy-to-use screening tool. Children classified as "low risk" have a 5% probability of being acutely malnourished, with only a 1% probability of a nutritional intervention during hospitalization.

Fecal secretory immunoglobulin A is increased in healthy infants who receive a formula with short-chain galacto-oligosaccharides and long-chain fructo-oligosaccharides.

In this double-blind, randomized, placebo-controlled study, we investigated the effect of an infant milk formula with 6 g/L short-chain galacto- and long-chain fructo-oligosaccharides [(scGOS/lcFOS) ratio 9:1] on the development of the fecal secretory immunoglobulin A (sIgA) response and on the composition of the intestinal microbiota in 215 healthy infants during the first 26 wk of life. The infants received breast milk or were randomized to receive an infant milk formula with or without scGOS/lcFOS. Stool samples were collected after 8 and 26 wk of intervention. The concentration of fecal sIgA was determined by ELISA, and the composition of the intestinal microbiota was determined by quantitative fluorescent in situ hybridization. The scGOS/lcFOS group and the control group were compared in the statistical analysis. A breast fed group was included as a reference. In total, 187 infants completed the study. After 26 wk of intervention, in infants that were exclusively formula fed, the concentration of sIgA was higher (P < 0.001) in the scGOS/lcFOS group (719 microg/g) than in the control group (263 microg/g). In addition, the percentages of bifidobacteria were higher in the scGOS/lcFOS group (60.4%) than in the control group (52.6%, P = 0.04). The percentages of Clostridium spp. were 0.0 and 3.27%, respectively (P = 0.006). In conclusion, an infant milk formula with 6 g/L scGOS/lcFOS results in higher concentrations of fecal sIgA, suggesting a positive effect on mucosal immunity.

Rotavirus gastroenteritis: epidemiological data from a regional hospital in Belgium.

The Belgian Institute of Public Health registered from 2000 to 2005 a yearly average of 6,790 hospital admissions for rotavirus gastroenteritis in children less than 5 years of age. Very efficacious rotavirus vaccines are available nowadays. The surveillance of hospitalisation due to rotavirus gastroenteritis is a good target for the follow-up of vaccine-related prevention. In a large regional Belgian hospital, rotavirus is associated with 12% to 21% of all hospitalisation days among children less than 2 years of age. The general implementation of rotavirus vaccination could dramatically reduce the hospitalisation of young children due to rotavirus gastroenteritis in developed countries.

Effect of prebiotic galacto-oligosaccharide, long-chain fructo-oligosaccharide infant formula on serum cholesterol and triacylglycerol levels.

OBJECTIVE: Cholesterol is a nutrient of essential importance in infant feeding because it is necessary in membrane development. In adults with high lipid levels, high doses of inulin (oligofructose) inconsistently decreased levels of serum cholesterol. The aim of the present study was to evaluate cholesterol and triacylglycerol levels in infants receiving a formula with a specific mixture of 0.6 g/100 mL of galacto-oligosaccharides (GOS) and long-chain fructo-oligosaccharides (lcFOS) in a ratio of 9/1, a control formula, or breast milk. Because the level of lcFOS in the infant milk is low, we hypothesized that there would be no differences between the formula groups. METHODS: Two hundred fifteen infants were included in a prospective, randomized, double-blinded, placebo-controlled trial during the first 6 mo of life. Formula-fed infants were randomized to receive a standard infant formula with a specific mixture of 0.6 g/100 mL of GOS/lcFOS, in a ratio of 9/1, or a control formula. Breast-fed infants were randomized to receive one of these two formulas after the mother had decided to discontinue breastfeeding. Serum levels of cholesterol, high-density lipoprotein, low-density lipoprotein (LDL), and triacylglycerol were determined at 8 and 26 wk of age and were provided for infants who received the GOS/lcFOS formula or control formula from birth or after cessation of breastfeeding and for the subgroups that were fully fed with breast milk and formula. RESULTS: One hundred eighty-seven infants completed the study. Total cholesterol and LDL levels at 8 and 26 wk were significantly lower in the formula-fed groups than in the breast-fed infants. There were no significant differences between the formula-fed groups. Levels of triacylglycerols and high-density lipoprotein did not differ between groups. CONCLUSION: Our study demonstrated no differences in total cholesterol and LDL cholesterol in infants receiving an infant formula with GOS/lcFOS from infants receiving a control infant formula. Furthermore, total cholesterol and LDL cholesterol levels were higher in breast-fed infants than in formula-fed infants.
