Outcomes of Children With Chronic Intestinal Failure: Experience Over 2 Decades at a Tertiary Paediatric Hospital

Gut microbiota and intestinal rehabilitation: a prospective childhood cohort longitudinal study of short bowel syndrome (the MIRACLS study): study protocol

INTRODUCTION

Short bowel syndrome (SBS) is the predominant cause of paediatric intestinal failure. Although life-saving, parenteral nutrition (PN) is linked to complications and may impact quality of life (QoL). Most children will experience intestinal rehabilitation (IR), but the mechanisms underpinning this remain to be understood. SBS is characterised by abnormal microbiome patterns, which might serve as predictive indicators for IR. We aim to characterise the microbiome profiles of children with SBS during IR, concurrently exploring how parental perspectives of QoL relate to IR.

METHODS AND ANALYSIS

This study will enrol a minimum of 20 paediatric patients with SBS (0-18 years). Clinical data and biological samples will be collected over a 2-year study period. We will apply 16S rRNA gene sequencing to analyse the microbiome from faecal and gut tissue samples, with additional shotgun metagenomic sequencing specifically on samples obtained around the time of IR. Gas chromatography with flame ionisation detection will profile faecal short-chain fatty acids. Plasma citrulline and urinary intestinal fatty acid binding proteins will be measured annually. We will explore microbiome-clinical covariate interactions. Furthermore, we plan to assess parental perspectives on QoL during PN and post-IR by inviting parents to complete the Paediatric Quality of Life questionnaire at recruitment and after the completion of IR.

ETHICS AND DISSEMINATION

Ethical approval was obtained from the East Midlands-Nottingham 2 Research Ethics Committee (22/EM/0233; 28 November 2022). Recruitment began in February 2023. Outcomes of the study will be published in peer-reviewed scientific journals and presented at scientific meetings. A lay summary of the results will be made available to participants and the public.

Transition from pediatric to adult care in patients with chronic intestinal failure on home parenteral nutrition: How to do it right?

BACKGROUND

Life expectancy of children with chronic intestinal failure (CIF) on home parenteral nutrition has greatly improved. Children are now able to grow into adulthood which requires transfer from pediatric to adult health care. A guideline for structured transition is lacking and the demand for a more standardized care for this patient group is necessary. Therefore, we investigated the perceptions of health care professionals from various disciplines working in this specific field, concerning effective interventions regarding transition to adult health care.

AIM

To create a standardized protocol which provides practical guidance for health care professionals in order to bridge the gap between pediatric and adult health care and to facilitate successful transition of children with chronic intestinal failure.

METHODS

A survey consisting of 20 interventions for transition was sent out to members of the Intestinal Failure working group of European Reference Network for Rare Inherited Congenital (gastrointestinal and digestive) Anomalies (ERNICA) and the Network of Intestinal Failure and Intestinal Transplant in Europe (NITE) group - European Society for Paediatric Gastroenterology Hepatology and Nutrition (ESPGHAN) healthcare professionals in 48 medical centers in various countries. Next to 20 interventions, an open-ended question to fill in any other suggestion with respect to most effective intervention was included. Interventions scoring higher than 80% by the participants were included in the protocol. Interventions scoring between 50% and 80% and other own suggestions were discussed during a consensus meeting and included when consensus, defined as unanimous agreement, was reached. Interventions scoring as effective by < 50% of participants were excluded directly.

RESULTS

A total of 80 healthcare professionals from 33 medical centers (participation rate 69%) participated. The protocol consisted of modifiable components expected to be targets of interventions. The most important key outcomes of the survey were: 1) assessment of patient's transition readiness and provision of knowledge to the patient by the pediatric team, 2) involvement of parents in the transition process, and 3) collaboration between the pediatric and adult chronic intestinal failure team. In addition it is advised that the transition process should start 1-2 years before transfer. A nurse specialist working in both services should form a bridge. All interventions must be tailor-made and based on the maturity of the patient.

CONCLUSION

This study provides a protocol describing transition of children with chronic intestinal failure from pediatric to adult care. This international protocol will serve as practical guidance for pediatric chronic intestinal failure which will provide a more structured, optimal transition process. It is advised to use this protocol as a formal checklist that can be placed in the patient's chart to review and track the transition process by CIF team members. Future research investigating transition readiness of CIF patients is needed.

Outcomes of Children With Short Bowel Syndrome: Experiences in a Multidisciplinary Intestinal Rehabilitation Unit Over Two Decades

BACKGROUND

Short bowel syndrome (SBS) is a rare but serious form of organ failure, and patients with SBS depend on total parenteral nutrition (PN) to maintain growth and development. The present study aimed to evaluate the experiences and outcomes of children with SBS managed by a multidisciplinary intestinal rehabilitation programme in a tertiary paediatric centre.

METHODS

A retrospective single-centre analysis of all paediatric patients with a clinical diagnosis of SBS between 2001 and 2022 was performed. Clinical outcomes and their predictors were extracted and analysed.

RESULTS

Of the 64 children included in the study, 43 (67%) had extensive necrotising enterocolitis. The median bowel length was 45 cm (interquartile range (IQR) = 18-65) and 18.9% (IQR = 10-28.5) of the expected length based on age. Over a mean follow-up period of 8.9 years, 57 patients (89%) survived, and 50 (78%) weaned off PN. The presence of intestinal failure-associated liver disease (IFALD) (OR = 6.375, p = 0.02) and patients managed before the introduction of fish oil-based PN in 2007 (OR = 5.895, p = 0.001) were significant predictors of mortality. There was an overall improvement in survival over time (p = 0.003). Ultrashort bowel length was not associated with significantly higher mortality (OR = 1.1, p = 0.65) but was a poor prognostic factor for weaning off PN (OR = 3.57, p = 0.004). Among all patients who weaned off PN, two had bowel lengthening procedures and one received a glucagon-like peptide 2 (GLP-2) analogue.

CONCLUSIONS

A multidisciplinary intestinal rehabilitation programme offers a comprehensive approach for patients with SBS and has been shown to be effective with favourable outcomes. Improvements in the choice of PN and the development of new treatment strategies potentially improved the survival and enteral autonomy of SBS patients.

Catheter salvage or removal in catheter-related bloodstream infections with Staphylococcus aureus in children with chronic intestinal failure receiving home parenteral nutrition and the use of prophylactic taurolidine catheter lock solution: A descriptive cohort study

BACKGROUND

Children with chronic IF require long-term home parenteral nutrition (HPN), administered through a central venous catheter. Catheter-related bloodstream infection (CRBSI) with Staphylococcus aureus is known to be a serious infection with a high mortality rate and risk of complications. A standardized protocol on the management of S aureus CRBSIs in children receiving HPN is lacking. The aim of this study is to evaluate the effectiveness and safety of the current management in an HPN expertise center in the Netherlands.

METHODS

We performed a retrospective descriptive cohort study between 2013 and 2022 on children 0-18 years of age with chronic IF requiring long-term HPN. Our primary outcomes were the incidence of S aureus CRBSI per 1000 catheter days, catheter salvage attempt rate, and successful catheter salvage rate. Our secondary outcomes included complications and mortality.

RESULTS

A total of 74 patients (39 male; 53%) were included, covering 327.8 catheter years. Twenty-eight patients (38%) had a total of 52 S aureus CRBSIs, with an incidence rate of 0.4 per 1000 catheter days. The catheter salvage attempt rate was 44% (23/52). The successful catheter salvage rate was 100%. No relapse occurred, and no removal was needed after catheter salvage. All complications that occurred were already present at admission before the decision to remove the catheter or not. No patients died because of an S aureus CRBSI.

CONCLUSION

Catheter salvage in S aureus CRBSIs in children receiving HPN can be attempted after careful consideration by a multidisciplinary team in an HPN expertise center.

Small bowel transplant - novel indications and recent progress

INTRODUCTION

Advances in the management of intestinal failure have led to a reduction in the number of intestinal transplants. The number of bowel transplants has been mainly stable even though a slight increase has been observed in the last 5 years.

AREAS COVERED

Standard indication includes patients with a reasonable life expectancy. Recent progress can be deduced by the increased number of intestine transplants in adults: this is due to the continuous improvement of 1-year graft survival worldwide (without differences in 3- and 5-year) associated with better abdominal wall closure techniques. This review aims to provide an update on new indications and changes in trends of pediatric and adult intestine transplantation. This analysis, which stretches through the past 5 years, is based on a collection of related manuscripts from PubMed.

EXPERT COMMENTARY

Intestinal transplants should be solely intended for a group of individuals for whom indications for transplantation are clear and both medical and surgical rehabilitations have failed. Nevertheless, many protocols developed over the years have not yet solved the key question represented by the over-immunosuppression. Novel indications and recent progress in the bowel transplant field, minimal yet consistent, represent a pathway to be followed.

Histopathological liver steatosis linked with high parenteral glucose and amino acid supply in infants with short bowel syndrome

BACKGROUND

Steatosis is a common feature of intestinal failure-associated liver disease (IFALD) in adult and older pediatric patients receiving long-term parenteral nutrition (PN). There are limited clinical data concerning steatosis in infants with short bowel syndrome (SBS). We investigated early histopathological steatosis and its association to PN.

METHODS

In this retrospective study, 31 patients with SBS had a diagnostic liver biopsy taken at the median age of 5 (IQR 3-8) months. Follow-up biopsy was available for 24 patients at the median age of 29 (IQR 14-52) months. We evaluated the biopsies for steatosis and other histopathological signs of IFALD and compared results with patient characteristics, PN composition, and liver biochemistry.

RESULTS

Diagnostic biopsies revealed steatosis in 8 (26%) patients. At the age of 3 months, patients with steatosis had received higher amounts of parenteral glucose: median 15.1 (IQR 12.4-17.2) vs 12.3 (8.7-14.4) g/kg/d (P = 0.04), amino acids: 2.9 (2.5-3.4) vs 2.2 (1.6-2.7) g/kg/d (P = 0.03), and energy: 87 (80-98) vs 73 (54-79) kcal/kg/d (P = 0.01) than those without steatosis. We detected no significant differences in parenteral lipid intake between the groups. Steatosis also associated with increased serum bile acid (P = 0.02), alanine aminotransferase (P = 0.0002), and aspartate aminotransferase (P = 0.001) levels.

CONCLUSIONS

In this cohort, high parenteral glucose, amino acid, and energy provision associated with liver steatosis in infants with SBS. We recommend monitoring of bile acid and transaminase levels while aiming for PN with balanced macronutrient supply according to current recommendations to protect the liver from steatosis.

The role of gastrostomy feeding during intestinal rehabilitation for children with short bowel syndrome

PURPOSE

Following extensive bowel resection, many children with short bowel syndrome (SBS) are routinely offered a placement of gastrostomy tube (G-tube) for feeding. This nutritional pathway is aimed to accommodate the gastric and small bowel motor disturbances related to SBS, and to promote weaning off parenteral nutrition (PN) to achieve enteral autonomy (EA). The aim of this study was to investigate the effect of gastrostomy feeding in outcomes of children with SBS.

METHODS

A retrospective cohort of all SBS children managed at our multidisciplinary Intestinal Rehabilitation Center as part of an Intestinal Rehabilitation Program. SBS was defined as PN dependence for more than six weeks following extensive bowel resection. Patients treated with G-tube feeding were compared with patients without G-tube in terms of PN duration, reaching EA, physical development, and surgical parameters.

RESULTS

A total of 36 SBS patients diagnosed between 2003 and 2022 were included. The most common etiologies included congenital intestinal atresia (31%) and necrotizing enterocolitis (25%). SBS-G-tube (group A) contained 20 children, and SBS (group B) contained 16 children. A total of 21 children reached EA (58%); ten from group A (50%), and 11 from group B (69%) (p > 0.05). Within EA patients, mean PN duration was 49 ± 44 months in group A, and 24 ± 33 months in group B (p > 0.05). Patients who reached EA had 22% longer residual small bowel when compared with PN-dependent patients (p = 0.003). However, the outcomes were adjusted for residual small and large bowel length and percentages, a residual ileocecal valve, and a colon in continuity with no differences between the groups. Two-thirds of children from group A reported G-tube related complications (mechanical, bleeding, or infections). We did not find differences in mean height and weight percentiles between the groups (p > 0.05).

CONCLUSION

We did not find significant advantage of gastrostomy feeding in reaching EA. Because there are surgical and mechanical complications related to this procedure, further prospective studies are required to determine G-tube relevance for children with SBS.

IFALD in children: What's new? A narrative review

Intestinal failure-associated liver disease (IFALD) is a progressive liver disease complicating intestinal failure (IF). It is a preventable and reversible condition, but at the same time, a potential cause of liver cirrhosis and an indication to combined or non-combined liver and small bowel transplantation. The diagnostic criteria are not yet standardized, so that its prevalence varies widely in the literature. Pathophysiology seems to be multifactorial, related to different aspects of intestinal failure and not only to the long-term parenteral nutrition treatment. The survival rates of children with IF have increased, so that the main problems today are preventing complications and ensuring a good quality of life. IFALD is one of the most important factors that limit long-term survival of patients with IF. For this reason, more and more interest is developing around it and the number of published articles is increasing rapidly. The purpose of this narrative review was to focus on the main aspects of the etiology, pathophysiology, management, prevention, and treatment of IFALD, based on what has been published mainly in the last 10 years. Controversies and current research gaps will be highlighted with the aim to pave the way for new project and high-quality clinical trials.

Chronic Intestinal Failure in Children: An International Multicenter Cross-Sectional Survey

Background: The European Society for Clinical Nutrition and Metabolism database for chronic intestinal failure (CIF) was analyzed to investigate factors associated with nutritional status and the intravenous supplementation (IVS) dependency in children. Methods: Data collected: demographics, CIF mechanism, home parenteral nutrition program, z-scores of weight-for-age (WFA), length or height-for-age (LFA/HFA), and body mass index-for-age (BMI-FA). IVS dependency was calculated as the ratio of daily total IVS energy over estimated resting energy expenditure (%IVSE/REE). Results: Five hundred and fifty-eight patients were included, 57.2% of whom were male. CIF mechanisms at age 1−4 and 14−18 years, respectively: SBS 63.3%, 37.9%; dysmotility or mucosal disease: 36.7%, 62.1%. One-third had WFA and/or LFA/HFA z-scores < −2. One-third had %IVSE/REE > 125%. Multivariate analysis showed that mechanism of CIF was associated with WFA and/or LFA/HFA z-scores (negatively with mucosal disease) and %IVSE/REE (higher for dysmotility and lower in SBS with colon in continuity), while z-scores were negatively associated with %IVSE/REE. Conclusions: The main mechanism of CIF at young age was short bowel syndrome (SBS), whereas most patients facing adulthood had intestinal dysmotility or mucosal disease. One-third were underweight or stunted and had high IVS dependency. Considering that IVS dependency was associated with both CIF mechanisms and nutritional status, IVS dependency is suggested as a potential marker for CIF severity in children.

Exploring the long-term risk factors associated with intestinal failure-associated liver disease in pediatric and adult patients: The role of lipid injectable emulsions in the development of liver disease

BACKGROUND

Despite parenteral nutrition (PN) being life sustaining, one of the risk factors associated with its long-term use is intestinal failure-associated liver disease (IFALD), which increases the risk for morbidity and mortality. This review examines some of the risk factors associated with IFALD.

METHODS

A literature review using the databases PubMed, EMBASE, and CINAHL between 2010 and 2020 was performed using search terms, including long-term total PN and liver failure, serum plant sterols and liver failure, and complications and PN. Articles in English using both human and animal participants were included.

RESULTS

The pathophysiology associated with PN and liver disease is multifactorial and influenced by the remaining small-bowel length, presence of the ileal cecal valve, lack of enteral stimulation, type of lipid injectable emulsion (ILE), plant sterol content, and excessive calories. The type of ILE plays a major role because of the phytosterol (PS) content, affecting the microbiome composition and inhibiting key gut signals. The PS content is highest in soy oil (SO)-based ILE, which increases inflammation and impairs biliary flow.

CONCLUSION

Serum PS correlates with liver biomarker abnormalities and is highest in SO-based ILE use compared with mixed-oil emulsions. Selection of a low-PS content ILE is recommended to reduce the risk of biliary cholestasis. Stimulation of the gut, if possible, is recommended to maintain gut integrity and reduce bacterial overgrowth. Fish oil (FO) shows promise in IFALD reversal however, large randomized controlled trials are needed to further establish support for the use of FO in adults.

Distal Small Bowel Resection Yields Enhanced Intestinal and Colonic Adaptation

BACKGROUND

Murine ileocecal resection (ICR) has been used to investigate intestinal adaptation. The established model often includes the sacrifice of significant length of the proximal colon. Here, we optimized a highly selective vascular approach to the ICR, with primary jejunal-colic anastomosis yielding maximal colonic preservation.

MATERIALS AND METHODS

Forty C57BL/6 mice underwent a highly vascularly selective ICR. The terminal branches of the ileocecal artery are isolated apart from the mesenteric branches supplying the small bowel to be resected. The distal 50% of small bowel and cecum are resected; a primary jejuno-colonic anastomosis is performed. Animals were sacrificed at postoperative weeks 2 (n = 10) and 10 (n = 29). Proximal 50% small bowel resection (SBR) with jejuno-ileal anastomosis was also performed for comparison.

RESULTS

The entire colon (with exception of the cecum) was preserved in 100% of animals. Ninety-seven percent of animals survived to postoperative week 10, and all exhibited structural adaptation in the remnant small intestine epithelium. Crypts deepened by 175%, and villi lengthened by 106%, versus 39% and 29% in the proximal SBR cohort, respectively. Colonic proliferation, structural adaptation, and functional adaptation (measured by p-histone 3, luminal-facing apical crypt border size, and sucrase isomaltase, respectively) were increased in ICR compared with proximal SBR.

CONCLUSIONS

Highly selective isolation of the cecal vasculature allows for greater colon preservation and yields enhanced remnant intestine epithelial adaptation. ICR is also associated with greater colonic adaptation and unique plasticity toward an intestinal phenotype. These findings underscore major differences between resection sites and offer insights into the critical adaptive mechanisms in response to massive intestinal loss.

Trends in Pediatric Intestinal Failure: A Multicenter, Multinational Study

OBJECTIVES

To assess the natural history and outcomes of children with intestinal failure in a large, multicenter, geographically diverse contemporary cohort (2010-2015) from 6 pediatric intestinal failure programs.

STUDY DESIGN

Retrospective analysis of a multicenter intestinal failure cohort (n = 443). Competing-risk analysis was used to obtain cumulative incidence rates for the primary outcome (enteral autonomy, transplantation, or death). The χ² test and Cox proportional hazard regression were used for bivariate and multivariable analyses.

RESULTS

The study cohort comprised 443 patients (61.2% male). Primary etiologies included short bowel syndrome (SBS), 84.9%; dysmotility disorder, 7.2%; and mucosal enteropathy, 7.9%. Cumulative incidences for enteral autonomy, transplantation, and death at 6 years of follow-up were 53.0%, 16.7%, and 10.5%, respectively. Enteral autonomy was associated with SBS, ≥50% of small bowel length, presence of an ileocecal valve (ICV), absence of portal hypertension, and follow-up in a non-high-volume transplantation center. The composite outcome of transplantation/death was associated with persistent advanced cholestasis and hypoalbuminemia; age <1 year at diagnosis, ICV, and intact colon were protective.

CONCLUSIONS

The rates of death and transplantation in children with intestinal failure have decreased; however, the number of children achieving enteral autonomy has not changed significantly, and a larger proportion of patients remain parenteral nutrition dependent. New strategies to achieve enteral autonomy are needed to improve patient outcomes.

Pediatric Home Parenteral Nutrition in France: A six years national survey

BACKGROUND AND AIMS

Home Parenteral Nutrition (HPN) is the cornerstone management for children suffering from chronic intestinal failure (CIF). In France, HPN is organized from a network of 7 certified centers located in University Hospitals spread across the national territory. This study aims to review the data involving children on HPN over a 6-years period in France to outline the global and continuous improvement in care.

PATIENTS AND METHODS

This cross-sectional study included all children enrolled in any of the 7 French HPN certified centers from January 1st, 2014 to December 31st, 2019. Data was recorded from annual databases provided by each center regarding: age at inclusion, indication and duration of HPN, type of intravenous lipid emulsion (ILE), outcome [PN weaning off, transfer to adult center, death, intestinal transplantation (ITx)], rate of catheter-related bloodstream infections (CRSBIs) for 1000 days of HPN, Taurolidine lock procedure (TLP) use and prevalence of cholestasis defined as conjugated bilirubin ≥20 μmol/l.

RESULTS

The number of patients increased by 43.6% from 268 in 2014 to 385 in 2019. According to the year of follow up, the indications for HPN were short bowel syndrome (SBS) (42.3-46.6%), congenital enteropathies (CE) (18.5-22.8%), chronic intestinal pseudo-obstruction syndrome (CIPOS) (13.0-16.3%), long segment Hirschsprung's disease (LSHD) (9.7-13.3%), Crohn's disease (CD) (1.6-2.6%) and other non-primary digestive diseases (NPDD) such as immune deficiency, cancer or metabolic disease (4.0-9.2%). The median age at discharge on HPN decreased from 11.7 months in 2014 to 8.3 months in 2019 (p < .001). By December 31st, 2019, 44.8% of children had left the HPN program after a median duration ranging between 39.9 and 66.4 months. Among these patients, 192 (74.2%) were weaned off PN (94.7% SBS), 41 (15.8%) were transferred to adult centers for CIPOS (42%), SBS (31%) or CE (27%), 21 died (8.1%) - mostly in relation to cancer or immune deficiency - and 5 were transplanted (1.9%): 4 underwent combined liver-intestine transplantation for LSHD (n = 2), SBS, CE and one multivisceral Tx for CIPOS. The use of a composite fish-oil based ILE increased from 67.4% in 2014 to 88.3% in 2019 (p < 0.001). CRBSIs dropped from 1.04 CRSBIs per 1000 days HPN in 2014 to 0.61 in 2019 (p < 0.001) while meantime, the percentage of children receiving TLP increased from 29.4% to 63.0% (p < 0.001). The prevalence of cholestasis (conjugated bilirubin ≥ 20 μmol/l) was low and stable between 4.1 and 5.9% of children during the study period.

CONCLUSION

In France, the number of children enrolled in a HPN program continuously increased over a 6 years period. SBS is the leading cause of CIF requiring HPN. The rate of CRBSIs dropped dramatically as the use of TLP increased. Mortality rate was low and mainly in relation to the underlying disease (cancer, immune deficiency). Cholestasis and intestinal Tx remained very rare.

In neonatal-onset surgical short bowel syndrome survival is high, and enteral autonomy is related to residual bowel length

BACKGROUND

In an era of improved management and treatment options, this study aims to describe the long-term outcomes and factors predictive of outcomes of neonatal-onset intestinal failure (IF) due to surgical short bowel syndrome (SBS).

METHODS

Retrospective, single-center cohort study of infants born between January 2011 and December 2018 with inclusion criteria: <44 weeks postmenstrual age at SBS diagnosis, <28 days on admission, parenteral nutrition dependence >60 days, and documented intestinal resection. Primary outcomes included survival and achievement of enteral autonomy (EA). Data analysis utilized Fisher.s exact test, Kruskal-Wallis test, survival analysis methods, Cox proportional hazards regression, linear regression and logistic regression.

RESULTS

Ninety-five patients (males 56%) were studied with median follow-up of 38 months (IQR 19, 59). Survival at last follow-up was 96%, and EA was achieved in 85%. Forty-eight patients had documented residual bowel length (RBL) with median length of 49 cm (IQR 36, 80). Survival in patients with RBL of <30cm (n = 8), 30-59cm (n = 19), and >60cm (n = 21) was 100%, 95%, and 95% respectively. Shorter RBL was associated with longer time to achieve EA (p = 0.007), but not with survival (p = 0.81). Delay in achieving EA was associated with absence of ileocecal valve (p = 0.002) and bloodstream infections (p < 0.001). Peak conjugated bilirubin correlated with increased mortality (p = 0.002).

CONCLUSION

Overall high rate of survival and achievement of EA was found in neonatal onset IF due to SBS. EA but not survival was correlated with RBL. Ileocecal valve, bloodstream infections, and conjugated bilirubin levels were the other predictive factors of outcomes.

Paediatric intestinal failure and transplantation

Intestinal failure is a complex and debilitating condition characterised by inadequate small intestinal function requiring parenteral or intravenous nutrition to maintain health and, for children, to enable growth and development. Although parenteral nutrition can be prescribed in many hospitals, children with chronic intestinal failure have improved outcomes when managed at a paediatric centre by a multidisciplinary team with specialised expertise in the comprehensive management of intestinal failure. Recent advances in the medical, surgical and nutritional approach have been effective at optimising intestinal rehabilitation and achieving enteral autonomy while limiting complications of intestinal failure. The role of intestinal transplantation in the management of the child with intestinal failure continues to evolve as an option for children with life-threatening complications of intestinal failure. The aim of this review is to highlight key advances in the care of children with intestinal failure.

New Insights Into the Indications for Intestinal Transplantation: Consensus in the Year 2019

In 2001, a Statement was published that described indications for intestinal transplantation in patients with intestinal failure expected to require parenteral nutrition indefinitely. Since 2001, advances in the management of intestinal failure including transplantation and patient survival, both on extended parenteral nutrition and after transplantation, have improved, leading to a reduction in the number of intestinal transplants worldwide from a peak of 270 per year in 2008 to 149 per year in 2017. These changes suggest that the original 2001 Statement requires reassessment. All patients with permanent intestinal failure should be managed by dedicated multidisciplinary intestinal rehabilitation teams. Under care of these teams, patients should be considered for intestinal transplantation in the event of progressive intestinal failure-associated liver disease, progressive loss of central vein access, and repeated life-threatening central venous catheter-associated infections requiring critical care. Additional indications for transplantation include large desmoid tumors and other intra-abdominal tumors with reasonable expectation of posttransplant cure, extensive mesenteric vein thrombosis and intestinal infarction, total intestinal aganglionosis, and nonrecoverable congenital secretory diarrhea. Quality of life typically improves after successful intestinal transplantation and may support the decision to proceed with transplantation when other indications are present. However, the requirement for life-long immunosuppression and its associated side effects preclude intestinal transplantation if motivated only by an expectation of improved quality of life. Increasing experience with intestinal transplantation and critical appraisal of transplant outcomes including graft survival and patient quality of life together with potential advances in immunosuppression can be expected to influence transplant practices in the future.

Neonatal Intestinal Failure Is Independently Associated With Impaired Cognitive Development Later in Childhood

OBJECTIVE

The impact of pediatric intestinal failure (IF) on neurodevelopment beyond infancy has not been systematically studied. Our aim was to evaluate cognitive and motor impairment and to identify risk factors for adverse outcomes among children with IF.

METHODS

We conducted a cross-sectional single-center study at the Helsinki University Children's Hospital. Patients with IF with >60 days of parental nutrition (PN) dependency aged between 3 and 16 years (n = 40) were invited to participate. The cognitive and motor skills were evaluated using validated tests: Wechsler Preschool and Primary Scale of Intelligence, 3rd edition, Wechsler Intelligence Scale for Children, 4th edition, and Movement Assessment Battery for Children, 2nd edition.

RESULTS

All the patients attending the study tests (n = 30, males = 24) were included. Their median age, gestational age, and birth weight was 7.5 (range 3-16) years, 35 (interquartile range [IQR] 28-38) weeks and 2238 (IQR 1040-3288) grams, respectively. Median duration of PN was 13 (IQR 5-37) months and 9 patients were currently on PN. Median intelligence quotient was 78 (IQR 65-91) and 10 (35%) patients had an intelligence quotient under 70 (-2 standard deviation). Significant motor impairment was detected in 10 patients (36%) and milder difficulties in 8 (28%). Adverse cognitive outcome was associated with neonatal short bowel syndrome, number of interventions under general anesthesia, and length of inpatient status, whereas adverse motor outcome was associated with prematurity.

CONCLUSION

Clinically significant cognitive and motor impairments are alarmingly common among neonatal patients with IF. We recommend early neurodevelopmental follow-up for all children with IF.
