Long-term outcome of home parenteral nutrition in patients with ultra-short bowel syndrome.

OBJECTIVE: The patients with ultra-short bowel syndrome (U-SBS) have been considered potential candidates for a preemptive/rehabilitative intestinal transplantation owing to the high risk of death from the underlying disease. We hypothesized that children with U-SBS, in the absence of intestinal failure-associated liver disease (IFALD), could also have a good rate of survival on home parenteral nutrition (HPN). METHODS: A prospective database from the "Bambino Gesù" Artificial Nutrition and Intestinal Failure Program was used to evaluate outcomes and morbidities of consecutive patients with ≤ 10 cm of small bowel enrolled since 2000. RESULTS: Eleven patients were identified with a median bowel length of 7.5 (3-9) cm. Eight patients developed IFALD, which reversed in 7 of them; the IFALD progressively worsened in 1 patient until death. One patient underwent isolated intestinal transplantation and 1 patient is no longer receiving parenteral nutrition (PN) and both are fully enterally fed. The other patients remained at least partially dependent on HPN. The number of days of inpatient care decreased in all of the patients except for the 1 who had repeated episodes of central line infections. CONCLUSIONS: The survival of patients with U-SBS receiving HPN was good. Although IFALD was frequent, it had been manageable in most of the patients, but in a single complex case, it led to death. The multidisciplinary management warranted to these patients to approach the school age, to grow, and to maintain the oral intake. Patients with U-SBS are rare, and to better understand their long-term survival, further studies, including more large patient populations, are required.

Neurological impairment and malnutrition in children: The role of home enteral nutrition in real life.

Objective: Recent decades have brought an increased survival of children with Neurologic Impairment (NI) but malnutrition and digestive comorbidity remain important challenges to face. We designed the present study to assess the course of nutritional status following standardized Home Enteral Nutrition (HEN) program and to evaluate impact of changing mode of feeding, as a part of overall multidisciplinary management, on digestive co-morbidity as Gastro-Esophageal Reflux Disease (GERD), Oropharyngeal Dysphagia (OPD), constipation and airway aspiration. Methods: We performed a retrospective analysis on NI children entered into Institutional HEN program due to NI disorders between January 2011 and 2019. Demographic, anthropometric characteristics (BMI z-score and weight for age z-score) and symptoms (GERD, OPD constipation and airway aspiration) were collected at the enrolment and during the follow up. Results: We enrolled 402 patients (median age: 39 months); overall survival was 97%. Nutritional status was significantly improved by HEN; in particular growth profile significantly changed within the first 2 years following HEN beginning; GERD and airways aspirations decreased after HEN beginning. Constipation and OPD remained unchanged over time. Conclusions: Malnutrition and digestive complaints are distinctive features of NI children. Nutritional status improve after 2 years from the beginning of standardized nutritional interventions. Overall multidisciplinary care, including standardized HEN protocols, seems to also impact on GERD and airway aspirations, which can decrease over time. It is possible that constipation and OPD, unchanged over time, are more dependent on underlying diseases than on overall treatments.

Wrist circumference is a clinical marker of insulin resistance in overweight and obese children and adolescents.

BACKGROUND: Excess fat is one of the main determinants of insulin resistance, representing the metabolic basis for developing future cardiovascular disease. The aim of the current study was to find an easy-to-detect clinical marker of insulin resistance which can be used to identify young subjects at increased risk of cardiovascular disease. METHODS AND RESULTS: Four-hundred and seventy-seven overweight/obese children and adolescents (mean age 10.31±2.80 years) were consecutively enrolled. Standard deviation score body mass index, fasting biochemical parameters, and homeostasis model assessment of insulin resistance were evaluated. Statistical differences were investigated using multiple linear regression analysis. Manual measure of wrist circumference was evaluated in all children and adolescents. Fifty-one subjects, randomly selected, underwent nuclear magnetic resonance imaging of the wrist to evaluate transversal wrist area at the Lister tubercle level. A statistically significant association was found between manual measure of wrist circumference and insulin levels or homeostasis model assessment of insulin resistance (ß=0.34 and 0.35, respectively; P<10(-5) for both comparisons). These associations were more significant than those between SD score body mass index and insulin levels or homeostasis model assessment of insulin resistance (ß=0.12 and 0.10, respectively; P≤0.02 for both comparisons). Nuclear magnetic resonance imaging acquisition clarified that the association between wrist circumference and insulin levels or homeostasis model assessment of insulin resistance reflected the association with bone tissue-related areas (P≤0.01 for both) but not with the adipose tissue ones (P>0.05), explaining 20% and 17% of the variances of the 2 parameters. CONCLUSIONS: Our findings suggest a close relationship among wrist circumference, its bone component, and insulin resistance in overweight/obese children and adolescents, opening new perspectives in the prediction of cardiovascular disease.

Lung ultrasound in the diagnosis and monitoring of 30 children with coronavirus disease 2019.

BACKGROUND: The coronavirus disease 2019 (COVID-19) has caused a new global pandemic and is responsible for millions of infections and thousands of deaths in the world. The lung ultrasound (LUS) is a noninvasive and easily repeatable tool and can be carried out by the pediatrician at the bedside of children with a consequent reduction in the risk of transmission of the virus. OBJECTIVE: We hypothesized that ultrasound findings in these patients would (1) be associated with their disease severity and (2) change over time in alignment with clinical outcome. METHODS: The study was made in the emergency department (ED) in a tertiary level pediatric hospital. All patients with swab-confirmed COVID-19 infection were subjected to a LUS within 6 h from admission and after 96 h. RESULTS: Among a total of 30 children, 18 (60%) were males, 4 reported exertional dyspnea, and only 1 chest pain. The mean oxygen saturation was 98.8 ± 1.0% in ambient air in the ED and no patient needed oxygen therapy during hospitalization. Children with moderate disease presented more B line (p = .03). After 96 h, we had observed ultrasound abnormality only in 20% of the children. We found a statistically significant reduction in pleural irregularities (30% vs. 16.7; p = .001) and in B lines (50% vs. 20%; p = .008). CONCLUSIONS: The LUS is a useful, feasible, and safe tool for the clinician to complement the clinical evaluation and to monitor the evolution of lung disease in children with COVID-19.

A neonatal cluster of novel coronavirus disease 2019: clinical management and considerations.

BACKGROUND: Lately, one of the major clinical and public health issues has been represented by Coronavirus disease of 2019 (COVID-19) during pregnancy and the risk of transmission of the infection from mother to child. Debate on perinatal management and postnatal care is still ongoing, principally questioning the option of the joint management of mother and child after birth and the safety of breastfeeding. According to the available reports, neonatal COVID-19 appears to have a horizontal transmission and seems to be paucisymptomatic or asymptomatic, compared to older age groups. The aim of this work is to describe a cluster of neonatal COVID-19 and discuss our experience, with reference to current evidence on postnatal care and perinatal management. METHODS: This is a retrospective observational case series of five mother-child dyads, who attended the Labor and Delivery Unit of a first-level hospital in Italy, in March 2020. Descriptive statistics for continuous variables consisted of number of observations, mean and the range of the minimum and maximum values. RESULTS: Five women and four neonates tested positive for Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). In one case, the mother-child dyad was separated and the neonate remained negative on two consecutive tests. Two positive neonates developed symptoms, with a predominant involvement of the gastrointestinal tract. Blood tests were unremarkable, except for a single patient who developed mild neutropenia. No complications occurred. CONCLUSIONS: We agree that the decision on whether or not to separate a positive/suspected mother from her child should be made on an individual basis, taking into account the parent's will, clinical condition, hospital logistics and the local epidemiological situation. In conformity with literature, in our study, affected neonates were asymptomatic or paucisymptomatic. Despite these reassuring findings, a few cases of severe presentation in the neonatal population have been reported. Therefore, we agree on encouraging clinicians to monitor the neonates with a suspected or confirmed infection.

Celiac disease in pediatric patients with autoimmune hepatitis: etiology, diagnosis, and management.

Celiac disease (CD) is defined as a permanent intolerance to ingested wheat gliadins and other cereal prolamins, occurring in genetically susceptible people. Persistent elevation of serum aminotransferase activity is expression of liver damage related to CD, which occurs in two distinctive forms. The most frequent is a mild asymptomatic liver injury, with a moderate increase of serum aminotransferase activities and a mild inflammatory portal and lobular infiltrate on liver biopsy (celiac hepatitis), reversible on a gluten-free diet (GFD). More rarely, severe and progressive inflammatory liver damage, induced by an autoimmune process and identified as autoimmune hepatitis (AIH), can develop and it is generally unaffected by gluten withdrawal. Surveys that included only pediatric patients report a wide range of prevalence of CD in AIH of 11.5-46% (mean 21.5%). CD and AIH share selected combinations of genes coding for class II human leukocyte antigens, which could explain their coexistence. Increased intestinal permeability and circulation of anti-tissue transglutaminase (tTG) have also been considered as further potential causes of liver damage in CD patients. tTG in the liver and in other extraintestinal tissues could modify other external- or self-antigens and generate different neo-antigens, which are responsible for liver injury in patients with CD. Patients with AIH represent a population at high risk for developing CD; screening for CD should be integrated into the diagnostic routine of all patients with AIH, with or without gastrointestinal manifestations, before starting immunosuppressive treatments. The only currently available treatment for CD is the GFD and the supportive nutritional care for iron, calcium, and vitamin deficiencies. Due to the difficulties of a GFD, in the past decade researchers have become increasingly interested in therapeutic alternatives to continuous or intermittent use of a GFD in patients with CD. Interventions addressed to correct the defect in the intestinal barrier are currently at the most advanced stage of clinical trials. The impact of a GFD on the outcome of AIH is not clear but it seems to be ineffective in the treatment of AIH. The early detection and treatment of CD, however, may prevent progression to end-stage liver failure.
