Research priorities in pediatric parenteral nutrition: a consensus and perspective from ESPGHAN/ESPEN/ESPR/CSPEN.

Parenteral nutrition is used to treat children that cannot be fully fed by the enteral route. While the revised ESPGHAN/ESPEN/ESPR/CSPEN pediatric parenteral nutrition guidelines provide clear guidance on the use of parenteral nutrition in neonates, infants, and children based on current available evidence, they have helped to crystallize areas where research is lacking or more studies are needed in order to refine recommendations. This paper collates and discusses the research gaps identified by the authors of each section of the guidelines and considers each nutrient or group of nutrients in turn, together with aspects around delivery and organization. The 99 research priorities identified were then ranked in order of importance by clinicians and researchers working in the field using a survey methodology. The highest ranked priority was the need to understand the relationship between total energy intake, rapid catch-up growth, later metabolic function, and neurocognitive outcomes. Research into the optimal intakes of macronutrients needed in order to achieve optimal outcomes also featured prominently. Identifying research priorities in PN should enable research to be focussed on addressing key issues. Multicentre trials, better definition of exposure and outcome variables, and long-term metabolic and developmental follow-up will be key to achieving this. IMPACT: The recent ESPGHAN/ESPEN/ESPR/CSPEN guidelines for pediatric parenteral nutrition provided updated guidance for providing parenteral nutrition to infants and children, including recommendations for practice. However, in several areas there was a lack of evidence to guide practice, or research questions that remained unanswered. This paper summarizes the key priorities for research in pediatric parenteral nutrition, and ranks them in order of importance according to expert opinion.

Social circumstances and medical complications in children with intestinal failure.

UNLABELLED: Although most children discharged on home parenteral nutrition (HPN) will achieve enteral autonomy, some remain parenteral nutrition dependent; those who develop life-threatening complications may undergo small bowel transplantation (SBTx). The aim of this study was to investigate the relationship between social circumstances, compliance and complications. SUBJECTS AND METHODS: An observational study in 2008-2012 on 64 children (34 HPN, 30 SBTx) from three units (two regional gastroenterology; one transplant). Social circumstances were assessed routinely as part of discharge planning; adherence by families to home care management was scored, and episodes of catheter-related blood stream infection and graft rejection were recorded for 2 years and related to compliance and social circumstances. RESULTS: A quarter of families had a disadvantaged parent: non-English speaking (n=11), unable to read (n=5), physical disability (n=3), mental health problems disclosed (n=10); 20% children were cared for by a lone parent. Discharge home was delayed by social factors (n=9) and need for rehousing (n=17, 27%). 17/34 (50%) of HPN and 12/30 (40%) of transplant families were assessed as fully adherent. 10 families were assessed as non-adherent, eight were subject to child protection review and care was taken over by another family member (n=3) or foster parents (n=2). The risk of catheter-related blood stream infection was increased by parental disadvantage and age <3 years (p<0.05). Poor compliance was associated with complications in HPN and SBTx recipients. CONCLUSIONS: Children receiving complex home care may be socially isolated and measures to support improved compliance such as increased community support, social care involvement and respite care may improve outcomes.

Recurrent life-threatening sepsis in intestinal failure: transplantation or foster care?

Parenteral nutrition has transformed the outlook for patients with intestinal failure, but is associated with serious long-term complications, including catheter-related blood stream infection, liver disease and loss of venous access. Risks can be significantly reduced by strict adherence to management regimens, such as catheter-care protocols, but intestinal transplantation is indicated when complications threaten survival. The responsibility of home parenteral nutrition as an alternative to long-term hospitalisation is welcomed by many parents, but represents a huge burden of care that sometimes proves beyond their capacity. We report two children with recurrent life-threatening central venous catheter infections who were removed from the intestinal transplant list following virtual cessation of infective episodes after going into foster care. These cases raise important issues about the level of family support offered, the role of non-compliance with treatment routines in relation to risk of complications, and how this should be assessed and monitored.

Taurolidine and catheter-related bloodstream infection: a systematic review of the literature.

BACKGROUND: Catheter-related bloodstream infection remains the most common serious complication associated with long-term parenteral nutrition. Taurolock (Bio-Implant HealthCare, Winsen, Germany), which contains taurolidine, is being marketed as a central venous catheter lock solution for decreasing the risk of catheter sepsis. AIM: To review available literature and examine the evidence for efficacy of taurolidine in prevention of central venous catheter-related infection. MATERIALS AND METHODS: Search of MEDLINE, Embase, and the Internet for all studies involving use of taurolidine to prevent central venous catheter infection. RESULTS: Six in vitro and 11 in vivo studies were assessed. Although in vivo studies suggest a possible useful role for taurolidine, the evidence base from clinical studies is poor, with much of it observational or of poor methodology. CONCLUSIONS: The evidence is insufficient to warrant routine use of taurolidine. However, results of in vitro studies are encouraging and further adequately powered and well-designed randomized trials are required.
