The impact of multi-disciplinary intestinal rehabilitation programs on the outcome of pediatric patients with intestinal failure: a systematic review and meta-analysis

Long-term teduglutide associated with improved response in pediatric short bowel syndrome-associated intestinal failure

OBJECTIVES

Patients with short bowel syndrome-associated intestinal failure (SBS-IF) require long-term parenteral nutrition and/or intravenous fluids (PN/IV) to maintain fluid or nutritional balance. We report the long-term safety, efficacy, and predictors of response in pediatric patients with SBS-IF receiving teduglutide over 96 weeks.

METHODS

This was a pooled, post hoc analysis of two open-label, long-term extension (LTE) studies (NCT02949362 and NCT02954458) in children with SBS-IF. Endpoints included treatment-emergent adverse events (TEAEs) and clinical response (≥20% reduction in PN/IV volume from baseline). A multivariable linear regression identified predictors of teduglutide response; the dependent variable was mean change in PN/IV volume at each visit over 96 weeks.

RESULTS

Overall, 85 patients were analyzed; 78 patients received teduglutide in the parent and/or LTE studies (any teduglutide [TED] group), while seven patients did not receive teduglutide in either the parent or LTE studies. Most TEAEs were moderate or severe in intensity in both groups. By week 96, 82.1% of patients from the any TED group achieved a clinical response, with a mean fluid decrease of 30.1 mL/kg/day and an energy decrease of 21.6 kcal/kg/day. Colon-in-continuity, non-White race, older age at baseline, longer duration of teduglutide exposure, and increasing length of remaining small intestine were significantly associated with a reduction in mean PN/IV volume requirements.

CONCLUSIONS

In pediatric patients with SBS-IF, teduglutide treatment resulted in long-term reductions in PN/IV requirements. The degree of PN/IV volume reduction depended on the duration of teduglutide exposure, underlying bowel anatomy, and demographics.

Improved long-term outcome of children with congenital diarrhea followed by an intestinal rehabilitation program

BACKGROUND

Long-term outcomes of congenital diarrheas and enteropathies (CODE) are poorly described. We evaluated the morbidity and mortality of children with CODE followed by an intestinal rehabilitation program (IRP) compared to children with short bowel syndrome (SBS).

METHODS

Matched case-control study of children with intestinal failure (IF) due to CODE (diagnosed between 2006 and 2020; N = 15) and SBS (N = 42), matched 1:3, based on age at diagnosis and duration of parenteral nutrition (PN). Nutritional status, growth, and IF-related complications were compared. Survival and enteral autonomy were compared to a nonmatched SBS cohort (N = 177).

RESULTS

Fifteen CODE patients (five males, median age 3.2 years) were followed for a median of 2.9 years. Eleven children were alive at the end of the follow-up, and two achieved enteral autonomy. The CODE group had higher median PN fluid and calorie requirements than their matched SBS controls at the end of the follow-up (83 vs. 45 mL/kg/day, p = 0.01; 54 vs. 30.5 kcal/kg/day, p < 0.01), but had similar rates of growth parameters, intestinal failure associated liver disease, central venous catheter complications and nephrocalcinosis. Kaplan-Meier analyses of 10-year survival and enteral autonomy were significantly lower in CODE patients compared to the nonmatched SBS population (60% vs. 89% and 30% vs. 87%, respectively; log-rank p < 0.008).

CONCLUSIONS

Despite higher PN needs in CODE, rates of IF complications were similar to matched children with SBS. Enteral autonomy and survival rates were lower in CODE patients. Treatment by IRP can mitigate IF-related complications and improve CODE patient's outcome.

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.

Adherence with post-hospitalization follow-up after pediatric critical illness due to respiratory failure

BACKGROUND

Adherence with follow-up appointments after a pediatric intensive care unit (PICU) admission is likely a key component in managing post-PICU sequalae. However, prior work on PICU follow-up adherence is limited. The objective of this study is to identify hospitalization characteristics, discharge child health metrics, and follow-up characteristics associated with full adherence with recommended follow-up at a quaternary care center after a PICU admission due to respiratory failure.

METHODS

We conducted a retrospective cohort study of patients ≤ 18 years with respiratory failure admitted between 1/2013-12/2014 to a quaternary care PICU. Post-hospitalization full adherence with recommended follow-up in the two years post discharge (1/2013-3/2017) at the quaternary care center was quantified and compared by demographics, baseline child health metrics, hospitalization characteristics, discharge child health metrics, and follow-up characteristics in bivariate and multivariate analyses. Patients were dichotomized into being non-adherent with follow-up (patients who attended less than 100% of recommended appointments at the quaternary care center) and fully adherent (patients who attended 100% of recommended appointments at the quaternary care center).

RESULTS

Of 155 patients alive at hospital discharge, 140 (90.3%) were recommended to follow-up at the quaternary care center. Of the 140 patients with recommended follow-up at the quaternary care center, 32.1% were non-adherent with follow-up and 67.9% were fully adherent. In a multivariable logistic regression model, each additional recommended unique follow-up appointment was associated with lower odds of being fully adherent with follow-up (OR 0.74, 95% CI 0.60-0.91, p = 0.005), and each 10% increase in the proportion of appointments scheduled before discharge was associated with higher odds of being fully adherent with follow-up (OR 1.02, 95% CI 1.01-1.03, p = 0.004).

CONCLUSIONS

After admission for acute respiratory failure, only two-thirds of children were fully adherent with recommended follow-up at a quaternary care center. Our findings suggest that limiting the recommended follow-up to only key essential healthcare providers and working to schedule as many appointments as possible before discharge could improve follow-up adherence. However, a better understanding of the factors that lead to non-adherence with follow-up appointments is needed to inform broader system-level approaches could help improve PICU follow-up adherence.

Ethnicity and socio-economic deprivation in children with intestinal failure in New Zealand: Disparities in incidence, but not in outcomes

AIMS

The New Zealand National Intestinal Failure and Rehabilitation Service (NZ-NIFRS) was established in October 2015 to gather longitudinal data on the aetiology, clinical course and outcomes of children with intestinal failure (IF). One main objective is to achieve health equity for patients with IF in NZ.

METHODS

Clinical outcomes (enteral autonomy, parenteral nutrition (PN) dependence, death or intestinal transplantation) for IF patients diagnosed from October 2015 to 2018 were analysed; comparisons were made by ethnicity and socio-economic status (SES) using published 'prioritised-ethnicity' health data and the NZ index of deprivation, respectively. The Cox proportional-hazards model was used to assess time to enteral autonomy.

RESULTS

Of the 208 patients (55.77% male, 43.75% preterm), 170 (81.73%) achieved enteral autonomy and 14 (6.73%) remained PN dependent. Pacific and Māori children accounted for 12.98% and 27.88% of the patient cohort, respectively, compared to 9.46% and 25.65% of the NZ paediatric population. More significantly, IF patients with a high NZ socio-economic deprivation score were overrepresented, with 35.92% in the highest deprivation quintile and 10.19% in the least deprived quintile, compared to 23.53% and 20.31%, respectively, of the NZ paediatric population. There were no significant differences in primary clinical outcomes for any patients based on ethnicity or SES.

CONCLUSION

While disparities in ethnicity and social deprivation do exist in the incidence of IF in NZ children, clinical outcomes are similar for children regardless of ethnicity or SES. NZ-NIFRS has achieved one of its core objectives: to achieve health equity for all patients with IF nationwide.

Innovative surgical techniques in the intestine and multivisceral transplant

PURPOSE OF REVIEW

This timely review delves into the evolution of multivisceral transplantation (MVT) over the past six decades underscoring how advancements in surgical techniques and immunosuppression have driven transformation, to provide insight into the historical development of MVT, shedding light on its journey from experimentation to a valuable clinical approach.

RECENT FINDINGS

The review presents contemporary enhancements in surgical methods within the context of intestinal transplantation. The versatility of MVT is emphasized, accommodating diverse organ combinations and techniques. Both isolated intestinal transplantation (IIT) and MVT have seen expanded indications, driven by improved parenteral nutrition, transplantation outcomes, and surgical innovations. Surgical techniques are tailored based on graft type, with various approaches for isolated transplantation. Preservation strategies and ostomy techniques are also covered, along with graft assessment advancements involving donor-specific antibodies.

SUMMARY

This review's findings underscore the remarkable evolution of MVT from experimental origins to a comprehensive clinical practice. The progress in surgical techniques and immunosuppression has broadened the spectrum of patients who can benefit from intestinal transplant, including both IIT and MVT. The expansion of indications offers hope to patients with complex gastrointestinal disorders. The detection of donor-specific antibodies in graft assessment advances diagnostic accuracy, ultimately improving patient outcomes.

Allied health and nursing practices in pediatric solid organ transplantation: An international survey

INTRODUCTION

With improved survival in pediatric solid organ transplantation (SOT) care has focused on optimizing functional, developmental, and psychosocial outcomes, roles often supported by Allied Health and Nursing professionals (AHNP). However, there is a scarcity of research examining frameworks of clinical practice.

METHODS

The International Pediatric Transplant Association AHNP Committee developed and disseminated an online survey to transplant centers as a quality improvement project to explore AHNP practice issues. Participant responses were characterized using descriptive statistics, and free-text comments were thematically analyzed. Responses were compared across professional groups; Group 1: Advanced Practice Providers, Group 2: Nursing, Group 3: Allied Health.

RESULTS

The survey was completed by 119 AHNP from across the globe, with responses predominantly (78%) from North America. Half of respondents had been working in pediatric transplant for 11+ years. Two-thirds of respondents were formally funded to provide transplant care; however, of these not funded, over half (57%) were allied health, compared to just 6% of advance practice providers. Advanced practice/nursing groups typically provided care to one organ program, with allied health providing care for multiple organ programs. Resource constraints were barriers to practice across all groups and countries.

CONCLUSION

In this preliminary survey exploring AHNP roles, professionals provided a range of specialized clinical care. Challenges to practice were funding and breadth of care, highlighting the need for additional resources, alongside the development of clinical practice guidelines for defining, and supporting the role of AHNP within pediatric SOT. Professional organizations, such as IPTA, can offer professional advocacy.

Cutoffs and Characteristics of Abnormal Bowel Dilatation in Pediatric Short Bowel Syndrome

OBJECTIVES

Although excessive intestinal dilatation associates with worsened outcomes in pediatric short bowel syndrome (SBS), little is known about the natural history and definition of pathological dilatation. We addressed fore-, mid-, and hind-gut dilatation in children with SBS, who had not undergone autologous intestinal reconstructive (AIR) surgery, in relation to controls.

METHODS

SBS children without history of AIR surgery (n = 59) and age-matched controls without any disclosed intestinal pathology (n = 140) were included. Maximum diameter of duodenum, small bowel (SB), and colon were measured in each intestinal contrast series during 2002 to 2020 and expressed as diameter ratio (DR) to L5 vertebrae height. Predictive ability of DR for weaning off parenteral nutrition (PN) was analyzed with Cox proportional hazards regression models using multiple cutoffs.

RESULTS

Duodenum (DDR), SB (SBDR), and colon (CDR) DR were 53%, 183%, and 23% higher in SBS patients compared to controls ( P < 0.01 for all). The maximal DDR and SBDR measured during follow-up is associated with current PN dependence and young age. DDR correlated with SBDR ( r = 0.586, P < 0.01). Patients with maximal DDR less than 1.5, which was also the 99th percentile for controls, were 2.5-fold more likely to wean off PN ( P = 0.005), whereas SBDR and CDR were not predictive for PN duration.

CONCLUSIONS

All segments of remaining bowel, especially SB, dilate above normal levels in children with SBS. In SBS children without AIR surgery, PN dependence and young age is associated with duodenal and small intestinal dilatation, while duodenal dilatation also predicted prolonged PN.

Nutrition and Intestinal Rehabilitation of Children With Short Bowel Syndrome: A Position Paper of the ESPGHAN Committee on Nutrition. Part 2: Long-Term Follow-Up on Home Parenteral Nutrition

Short bowel syndrome (SBS) is the leading cause of intestinal failure (IF) in children. The preferred treatment for IF is parenteral nutrition which may be required until adulthood. The aim of this position paper is to review the available evidence on managing SBS and to provide practical guidance to clinicians dealing with this condition. All members of the Nutrition Committee of the European Society for Paediatric Gastroenterology Hepatology and Nutrition (ESPGHAN) contributed to this position paper. Some renowned experts in the field joined the team to guide with their expertise. A systematic literature search was performed from 2005 to May 2021 using PubMed, MEDLINE, and Cochrane Database of Systematic Reviews. In the absence of evidence, recommendations reflect the expert opinion of the authors. Literature on SBS mainly consists of retrospective single-center experience, thus most of the current papers and recommendations are based on expert opinion. All recommendations were voted on by the expert panel and reached >90% agreement. This second part of the position paper is dedicated to the long-term management of children with SBS-IF. The paper mainly focuses on how to achieve intestinal rehabilitation, treatment of complications, and on possible surgical and medical management to increase intestinal absorption.

A nordic multicenter study on contemporary outcomes of pediatric short bowel syndrome in 208 patients

BACKGROUND & AIMS

Despite advances in the management of short bowel syndrome related intestinal failure (SBS-IF), large-scale contemporary pediatric studies are scarce. The aim of this multicenter study was to assess key outcomes and clinical prognostic factors in a recent Nordic pediatric SBS-IF population.

METHODS

Patients with SBS-IF treated during 2010-2019, whose parenteral support (PS) started at age <1 year and continued >60 consecutive days were included and retrospectively reviewed. All six participating centers followed multidisciplinary SBS-IF management. Risk factors for PS dependency, intestinal failure associated liver disease (IFALD) and mortality were assessed with Cox regression and Kaplan Meier analyses. IFALD was defined with serum liver biochemistry levels.

RESULTS

Among 208 patients, SBS-IF resulted from NEC in 49%, gastroschisis w/wo atresia in 14%, small bowel atresia in 12%, volvulus in 11%, and other diagnoses in 14%. Median age-adjusted small bowel length was 43% (IQR 21-80%). After median follow up of 4.4 years (IQR 2.5-6.9), enteral autonomy was reached by 76%, none had undergone intestinal transplantation, and overall survival was 96%. Half of deaths (4/8) were caused by septic complications. Although biochemical cholestasis occurred only in 3% at latest follow-up and none of deaths were directly caused by IFALD, elevated liver biochemistry (HR 0.136; P = 0.017) and shorter remaining small bowel (HR 0.941; P = 0.040) predicted mortality. Shorter remaining small bowel and colon, and presence of end-ostomy were the main predictors of PS dependency, but not IFALD. Patients with NEC reached enteral autonomy more efficiently and had decreased incidence of IFALD compared to other etiologies.

CONCLUSIONS

Although with current multidisciplinary management, prognosis of pediatric SBS is encouraging, septic complications and IFALD still associated with the remaining low mortality rate.

Pediatric intestinal rehabilitation

PURPOSE OF REVIEW

The intestinal rehabilitation program (IRP) is a comprehensive treatment strategy that employs various approaches implemented by multidisciplinary teams to treat intestinal failure in children. This program has shown promising results, such as reducing complications and improving prognosis and quality of life (QOL). In this review, we discuss the current status of this program and relevant topics.

RECENT FINDINGS

IRP includes the prevention and treatment of various complications such as intestinal failure associated liver disease, catheter-related bloodstream infection or sepsis, and venous thromboembolism. In addition, treatment strategies such as glucagon-like peptide-2 analogs, surgical interventions, and intestinal transplantation have evolved over time and have contributed to improved outcomes. In addition, the scope and regions for IRP activities have expanded.

SUMMARY

IRP improves the prognosis and QOL of children with intestinal failure. The development of new drugs, surgical methods, and treatment strategies is expected to improve the current and future status of pediatric patients with intestinal failure. Furthermore, international institutions must collaborate, share knowledge, conduct joint research, and establish patient registries to advance IRP progress.

New insights into the pathogenesis of necrotizing enterocolitis and the dawn of potential therapeutics

Necrotizing enterocolitis (NEC) is a devastating gastrointestinal disorder in premature infants that causes significant morbidity and mortality. Research efforts into the pathogenesis of NEC have discovered a pivotal role for the gram-negative bacterial receptor, Toll-like receptor 4 (TLR4), in its development. TLR4 is activated by dysbiotic microbes within the intestinal lumen, which leads to an exaggerated inflammatory response within the developing intestine, resulting in mucosal injury. More recently, studies have identified that the impaired intestinal motility that occurs early in NEC has a causative role in disease development, as strategies to enhance intestinal motility can reverse NEC in preclinical models. There has also been broad appreciation that NEC also contributes to significant neuroinflammation, which we have linked to the effects of gut-derived pro-inflammatory molecules and immune cells which activate microglia in the developing brain, resulting in white matter injury. These findings suggest that the management of the intestinal inflammation may secondarily be neuroprotective. Importantly, despite the significant burden of NEC on premature infants, these and other studies have provided a strong rationale for the development of small molecules with the capability of reducing NEC severity in pre-clinical models, thus guiding the development of specific anti-NEC therapies. This review summarizes the roles of TLR4 signaling in the premature gut in the pathogenesis of NEC, and provides insights into optimal clinical management strategies based upon findings from laboratory studies.

An Overview of Short-Bowel Syndrome in Pediatric Patients: Focus on Clinical Management and Prevention of Complications

Short-bowel syndrome (SBS) in pediatric age is defined as a malabsorptive state, resulting from congenital malformations, significant small intestine surgical resection or disease-associated loss of absorption. SBS is the leading cause of intestinal failure in children and the underlying cause in 50% of patients on home parental nutrition. It is a life-altering and life-threatening disease due to the inability of the residual intestinal function to maintain nutritional homeostasis of protein, fluid, electrolyte or micronutrient without parenteral or enteral supplementation. The use of parenteral nutrition (PN) has improved medical care in SBS, decreasing mortality and improving the overall prognosis. However, the long-term use of PN is associated with the incidence of many complications, including liver disease and catheter-associated malfunction and bloodstream infections (CRBSIs). This manuscript is a narrative review of the current available evidence on the management of SBS in the pediatric population, focusing on prognostic factors and outcome. The literature review showed that in recent years, the standardization of management has demonstrated to improve the quality of life in these complex patients. Moreover, the development of knowledge in clinical practice has led to a reduction in mortality and morbidity. Diagnostic and therapeutic decisions should be made by a multidisciplinary team that includes neonatologists, pediatric surgeons, gastroenterologists, pediatricians, nutritionists and nurses. A significant improvement in prognosis can occur through the careful monitoring of nutritional status, avoiding dependence on PN and favoring an early introduction of enteral nutrition, and through the prevention, diagnosis and aggressive treatment of CRSBIs and SIBO. Multicenter initiatives, such as research consortium or data registries, are mandatory in order to personalize the management of these patients, improve their quality of life and reduce the cost of care.

Intestinal failure among adults and children: Similarities and differences

Intestinal failure (IF) is a complex medical condition that is caused by a constellation of disorders, resulting in the gut's inability to adequately absorb fluids and nutrients to sustain hydration, growth, and survival, thereby requiring the use of parenteral fluid and/or nutrition. Significant advancements in intestinal rehabilitation have resulted in improved survival rates for individuals with IF. There are distinct differences, however, related to etiology, adaptive potential and complications, and medical and surgical management when comparing children with adults. The purpose of this review is to contrast the similarities and differences between these two distinct groups and provide insight for future directions, as a growing population of pediatric patients will cross into the adult world for IF management.

The North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition Position on the Role of the Registered Dietitian Nutritionist in the Care of the Pediatric Patient With Chronic Gastrointestinal Diseases

The optimization of nutrition is essential for the growth and development of all children, including those with gastrointestinal (GI) conditions that can variably affect nutrient intake, absorption, or metabolism. Registered Dietitian Nutritionists (RDNs) are essential partners in delivering high quality care for pediatric GI disorders, but limited evidence is available to support the role of the RDN in the care of these patients. This position paper outlines the evidence supporting the role of the RDN in the management of chronic pediatric GI issues in both inpatient and outpatient settings. Gaps in the literature, opportunities for future research, and barriers to RDN access are discussed.

Stress, anxiety, depression, and health-related quality of life in caregivers of children with intestinal failure receiving parenteral nutrition: A cross-sectional survey study

BACKGROUND

Improved survival rates for children with intestinal failure (IF) have resulted in an increased population of children receiving long-term parenteral nutrition (PN). Our objective was to determine burden on caregivers of children with IF receiving long-term PN.

METHODS

We performed a cross-sectional study of caregivers of children with IF receiving long-term PN in our intestinal rehabilitation program. A healthy comparison group matched on age of the child was enrolled. All participants completed standardized questionnaires, including the Parental Stress Index - Short Form (PSI-SF), Hospital Anxiety and Depression Scale (HADS), and PedsQL Family Impact Module (PedsQL FIM). Univariate analysis was completed using a Student t test and chi-square, with an alpha value of <0.05 considered significant.

RESULTS

Thirty-eight caregivers of children with IF and 29 caregivers of healthy children consented, with response rates of 89% and 96.5%, respectively. Our study demonstrated increased stress for caregivers compared with comparison parents (PSI-SF total score of 83 [SD = 26.8] vs 62.9 [SD = 13.5]; P < 0.01). Caregivers had increased anxiety (HADS anxiety score of 9.3 [SD = 4.8] vs 6.7 [SD = 3.2]; P = 0.02) and higher depression scores (HADS depression score of 6.3 [SD = 4.3] vs 4.1 [SD = 2.6]; P = 0.02) compared with the comparison group. Caregivers of children with IF demonstrated decreased health-related quality of life (HRQoL) (reduced PedsQL FIM total score of 50.6 [SD = 18.2] vs 84.1 [SD = 20.5]; P < 0.01).

CONCLUSIONS

Our results demonstrated significant burden of care in caregivers of children with IF receiving long-term PN, with elevated stress, anxiety, and depression and decreased HRQoL.

Factors influencing enteral autonomy after autologous gastrointestinal reconstructive surgery: A two-centre UK perspective

BACKGROUND AND AIMS

The implementation of multidisciplinary care and improvements in parenteral nutrition (PN) in patients with short bowel syndrome (SBS) have led to better outcomes and higher survivability. Autologous gastrointestinal reconstructive (AGIR) surgery can reduce the duration on PN and lead to earlier enteral autonomy (EA). Our aim was to investigate the effect of SBS aetiology and other predictors on the achievement of enteral autonomy following AGIR surgery.

METHODS

Retrospective review of all patients undergoing AGIR surgery in two tertiary paediatric surgical units, between 2010 and 2021. Continuous data is presented as median (range).

RESULTS

Twenty-seven patients underwent 29 AGIR procedures (20 serial transverse enteroplasties (STEP), 9 longitudinal intestinal lengthening and tailoring (LILT)) at an age of 6.6 months (1.5 - 104.5). EA rate was 44% at 13.6 months after surgery (1 - 32.8). AGIR procedures achieved an increase in small bowel length of 70% (pre-operative 46.5 vs 77 cm, p = 0.003). No difference was found between STEP and LILT (p = 0.84). Percentage of expected small bowel length (based on the child's weight) was a strong predictor of EA (bowel length >15% - EA 80% vs bowel length ≤15% - EA 17%, p = 0.008). A diagnosis of gastroschisis showed a negative non-significant correlation with the ability to achieve EA (25% vs 60%, p = 0.12). Overall survival rate was 96%.

CONCLUSION

AGIR surgery is an important tool in the multidisciplinary management of children with SBS. Percentage of expected small length and aetiology of SBS are likely predictors of achievement of EA in patients undergoing AGIR surgery.

Predictors of Social-Emotional Development and Adaptive Functioning in School-Age Children with Intestinal Failure

OBJECTIVES

Despite a focus on neurocognition in pediatric intestinal failure (IF) to date, we examined social-emotional and adaptive functioning.

METHODS

Children (N = 63) in our IF rehabilitation program underwent neuropsychological assessments including caregiver- and teacher-reported questionnaires. Results were compared to norms using z-tests. Caregiver and teacher reports were compared using t tests. Medical and demographic factors were examined in an exploratory manner using correlation and targeted regression analyses, adjusting for gestational age and full-scale IQ.

RESULTS

Caregiver and teacher reports indicated poorer executive, internalizing, behavioral, and adaptive functioning compared to norms. Teachers reported more executive dysfunctions than caregivers. Necrotizing enterocolitis diagnosis predicted internalizing emotional problems. Immigrant status predicted poorer social and practical adaptive functioning. Living with biological parents predicted fewer externalizing emotional and behavioral problems.

CONCLUSIONS

The group displayed social-emotional and adaptive functioning concerns. Identifying medical and demographic risks can allow for screening and intervention.

Muscle Strength, Agility, and Body Composition in Children With Intestinal Failure on Parenteral Nutrition

OBJECTIVES

With increasing number of children with intestinal failure (IF) on long-term parenteral nutrition (PN), this study assesses the impact of IF on muscle strength, speed, and agility and body composition (BC), identifying clinical factors that may predict impairment.

METHODS

Cross-sectional study in children 5-18 years with IF on PN. Assessments included Bruininks-Oseretsky Test of Motor Proficiency-2 strength and agility subtest (BOT-2), and grip strength. BC data from dual-energy x-ray absorptiometry (DXA) measurements and clinical variables were collected by chart abstraction. Data were compared to age and sex matched controls and population norms.

RESULTS

Twenty-one children with IF (14 males), median age 8.33 (IQR: 6.96-11.04) years and 33 controls (20 males), 8.25 (6.67-10.79) years were included. Strength and agility ( P &lt; 0.001) and grip strength ( P = 0.001) differed between groups. Nine of 21 (43%) of children with IF scored &gt;1 standard deviation (SD) below mean on BOT-2 and 13 of 21 (62%) had grip strength &gt;1 SD below mean. DXA measurements showed 10 of 18 (56%) of children had lower fat-free mass (FFM)% and higher fat mass (FM)% than reference norms. Decreased FFM% was associated with lower BOT-2 scores ( r = 0.479; P = 0.044) and grip strength scores &gt;1 SD below mean ( P = 0.047). Additional clinical factors significantly impacting strength and agility included prematurity, height, hospitalizations, sepsis, and small bowel length.

CONCLUSIONS

Children with IF are at risk of decreased muscle strength and agility, along with altered BC. Ongoing medical, nutritional, and rehabilitation intervention is vital to optimize outcomes.

A beautiful struggle: Parent-perceived impact of short bowel syndrome on child and family wellbeing

BACKGROUND

Despite considerable improvements in outcomes for children with short bowel syndrome (SBS), many clinicians remain pessimistic about long-term quality of life (QoL) for this population.

METHODS

The validated FaMM tool was used to measure parent-perceived impact of the child's condition on child and family life. Partnered disease-specific survey questions relevant to child's overall wellbeing and family function were additionally completed and reported. The cross-sectional surveys were distributed to a convenience sample of parents of children with SBS. Child and family wellbeing were described and compared across child age group and involvement of an intestinal rehabilitation program (IRP). Multivariate regression analyses investigated associations between outcomes and IRP management. Open-ended responses were analyzed to investigate perceived impact of the child's SBS on the parent.

RESULTS

Seventeen parents completed both surveys; 71% perceived child QoL as higher today than what they had originally been told to expect. Child daily life and family difficulty scores suggest parents perceived both to be fairly "normal". While acknowledging effort invested in condition management, parents perceived high competence in managing their child's condition; 56% perceived personal growth resulting from their child's SBS journey. IRP management was associated with better child daily life (4.11, p = 0.015), family difficulty (-4.85, p = 0.048), and family management ability (4.28, p = 0.014) scores.

CONCLUSIONS

Many parents perceive child and family life with SBS to be fairly "normal", manage their child's care with great competence, and report personal growth because of their child's SBS journey. Additional research inclusive of diverse patient and parent backgrounds is warranted.

Management of pediatric intestinal failure related to short bowel syndrome

Intestinal failure (IF) secondary to short bowel syndrome is a challenging and complex medical condition with significant risk for surgical and medical complications. Significant advancements in the care of this patient population have led to improved survival rates. Due to their intensive medical needs children with IF are at risk for long-term complications that require comprehensive management and close monitoring. The purpose of this paper is to review the available literature emphasizing the surgical aspects of care for children with IF secondary to short bowel syndrome. A key priority in the surgical care of this patient population includes strategies to preserve available bowel and maximize its function. Utilization of novel surgical techniques and autologous bowel reconstruction can have a significant impact on children with IF secondary to short bowel syndrome related to the function of their bowel and ability to achieve enteral autonomy. It is also important to understand the potential long-term complications to ensure strategies are put in place to mitigate risk with early detection to improve long-term outcomes.

An in-line digestive cartridge increases enteral fat and vitamin absorption in a porcine model of short bowel syndrome

BACKGROUND & AIMS

Short bowel syndrome (SBS) occurs after intestinal loss resulting in parenteral nutrition dependence and micronutrient deficiencies, which may lead to life-limiting complications. ALC-078 is a cartridge containing immobilized lipase that connects in-line with enteral feeding sets and digests fats in enteral nutrition (EN). In this study, we evaluate the efficacy of ALC-078 to improve fat and nutrient absorption in a porcine SBS model.

METHODS

Fifteen male Yorkshire piglets were assessed. Animals were randomized to no intestinal resection (n = 5), 75% resection (n = 5), or 75% resection + ALC-078 (n = 5). After recovery, animals were treated for 14 days. Piglets received 60% of nutrition from continuous EN and 40% from chow. The degree of fat malabsorption was determined by the coefficient of fat absorption (CFA) following a 72-h stool collection. Body weight, fat-soluble vitamins, and nutritional markers were assessed.

RESULTS

Adverse events were similar across the three groups (P = 1.00). ALC-078-treated animals had similar weight gain compared to resected piglets. Resected animals had a lower CFA compared to unresected controls (79.3% vs. 95.2%, P = 0.01) while there was no significant difference in the ALC-078 animals (87.1% vs. 95.2%, P = 0.19). Between Study Days 1 and 15, ALC-078 animals had increased concentrations of vitamin D (12.2 vs. 8.7 ng/mL, P = 0.0006), and vitamin E (4.3 vs. 2.5 mg/L, P = 0.03). These markers did not significantly change in untreated resected animals.

CONCLUSION

ALC-078 increases the absorption of fat-soluble vitamins and may improve fat malabsorption. Future studies should determine whether ALC-078 can reduce PN dependence and if these findings translate to human patients with SBS.

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.

Spectrum of Interventional Procedures During Hybrid Central Line Placement in Pediatric Intestinal Rehabilitation Patients With End-Stage Vascular Access

Background

Loss of available central vein access sites for parenteral nutrition delivery represents one of the main indications for intestinal transplantation in children with intestinal failure. Placement of central venous catheters can be challenging in advanced loss of patent venous pathways. We recently described the hybrid technique (interventional plus surgical approach) of central line placement in children. The aim of this study was to describe and analyze the interventions used during the hybrid procedures regarding feasibility, safety and outcome.

Methods

We retrospectively analyzed the course of all children in our intestinal rehabilitation program undergoing hybrid central line placement. We evaluated patients' conditions, interventional techniques and surgical peculiarities as well as outcome.

Results

203 children were treated in our intestinal rehabilitation program between 2010 and 2021. Due to loss of venous access, hybrid technique was performed in 53 children during 76 interventions. In 40 cases the same vessel was reused via Seldinger technique. Among the 30 ultrasound-guided new vessel punctures, 12 were performed by puncture of collateral vessels. Extended interventions due to thoracic central venous obstruction and/or thrombosis requiring additional access via a femoral vein for rehabilitation of the vascular system was performed during 29 procedures including catheter extraction (1), angioplasties (18), stent placement (1), revascularization (5) and thrombectomy (4). Placement of a central line was not possible in 6 children which eventually underwent extended thoracic/vascular surgery: in three children the previously placed catheter could not be removed, in one child, placement of a thrombectomy-catheter was not possible because of inferior vena cava occlusion, and in two children, revascularization failed. Intestinal transplantation was considered in one patient because of impending loss of vascular access. Two self-limiting minor extravasations and one intervention-associated pericardial effusion occurred.

Conclusions

Hybrid interventions for central venous catheter placement and vascular rehabilitation enable a high success rate in children with intestinal failure and end-stage vascular access, circumventing the need for intestinal transplantation or advanced surgery. The relevant procedures are complex and require a foresighted and individualized approach with a wide range of interventional techniques. If performed with expertise, this combined interventional/surgical approach is feasible and safe.

Impact of the acuity circle model for liver allocation on multivisceral transplant candidates

Liver allocation was updated on February 4, 2020, replacing a Donor Service Area (DSA) with acuity circles (AC). The impact on waitlist outcomes for patients listed for combined liver-intestine transplantation (multivisceral transplantation [MVT]) remains unknown. The Organ Procurement and Transplantation Network/United Network for Organ Sharing database was used to identify all candidates listed for both liver and intestine between January 1, 2018 and March 5, 2021. Two eras were defined: pre-AC (2018-2020) and post-AC (2020-2021). Outcomes included 90-day waitlist mortality and transplant probability. A total of 127 adult and 104 pediatric MVT listings were identified. In adults, the 90-day waitlist mortality was not statistically significantly different, but transplant probability was lower post-AC. After risk-adjustment, post-AC was associated with a higher albeit not statistically significantly different mortality hazard (sub-distribution hazard ratio[sHR]: 8.45, 95% CI: 0.96-74.05; p = .054), but a significantly lower transplant probability (sHR: 0.33, 95% CI: 0.15-0.75; p = .008). For pediatric patients, waitlist mortality and transplant probability were similar between eras. The proportion of patients who underwent transplant with exception points was lower post-AC both in adult (44% to 9%; p = .04) and pediatric recipients (65% to 15%; p = .002). A lower transplant probability observed in adults listed for MVT may ultimately result in increased waitlist mortality. Efforts should be taken to ensure equitable organ allocation in this vulnerable patient population.

Intestinal failure in Finland: prevalence and characteristics of an adult patient population

OBJECTIVES

Details of intestinal failure in the Finnish adult population are unknown. This study aimed to specify the intestinal failure prevalence and to clinically characterize the patient population in Finland.

METHODS

All Finnish healthcare units with the potential of providing parenteral support received an electronic survey to report whether they had patient(s) aged ≥18 years on long-term (≥120 days) parenteral support due to intestinal failure. Patient details came from patient records. IBM SPSS v.25 was used to analyze descriptive statistics.

RESULTS

Of the 74 patients, 52 were included after confirming parenteral support indication from the records. The adult intestinal failure prevalence for 2017 was 11.7 per million, 95% confidence interval: 8.9-15.3. Most patients were women (69%), and the median age was 62 (45-72) years. Short bowel syndrome was the most frequent intestinal failure mechanism (73%), and surgical complication the most frequent underlying diagnosis (29%). Of patients, 66% represented the clinical classification category parenteral nutrition 1 or parenteral nutrition 2. Median Charlson Comorbidity Index was one (0-2.8); hypertension (37%) and diabetes (23%) were the most frequent comorbidities. Patients received seven (3.5-7) parenteral support infusions weekly, and eight patients (15%) were on fluids and electrolytes only. The median duration of parenteral support was 27.5 (11.3-57.3) months. Ten patients ceased parenteral support during 2017 after a median of 20.0 (9.0-40.3) parenteral support months. Eight weaned off parenteral support, one ran out of catheter sites, and one died.

CONCLUSION

Prevalence and patient characteristics of adult intestinal failure in Finland are similar to those in other Western countries.

Adaptation Processes of the Remaining Jejunum or Ileum after Extensive Intestinal Resection

PURPOSE

To compare the adaptation processes of the remaining jejunum or ileum after extensive intestinal resection in a growing animal model.

MATERIALS AND METHODS

Forty 21-day old rats were divided into four groups: JG: remaining jejunum group - ileal enterectomy; IG: ileum remaining group - jejunum enterectomy; SHAM: sham-operated group - open-and-close laparotomy; and NO: non-operated animals.

RESULTS

After 3 weeks, JG and IG animals had decreased weights comparing to SHAM and NO animals (p = 0.017 and p = 0.005, respectively). The histomorphometric analysis showed that in JG animals the villi were higher than in SHAM, NO, and IG animals (p = 0.007, p = 0.008, and p = 0.01), the depth of crypts in JG and IG animals was greater than in NO and SHAM animals (p = 0.03, p = 0.002, and p = 0.003 respectively), and muscle layer thickness of the jejunum of JG animals had values greater than SHAM and NO animals (p = 0.01 and p = 0.02, respectively). The Ki-67 expression in the ileum was higher in comparison with the jejunum (p = 0.014). The pro-apoptotic gene (Bax) expression was decreased in JG animals compared to IG, SHAM, and NO animals (p = 0.013, p = 0.024, and p = 0.021). The anti-apoptotic gene (Bcl-XL) expression was decreased in JG animals in comparison to IG and NO animals (p = 0.002 and p = 0.046) although it was increased in the colon of IG animals in comparison to JG, SHAM, and NO animals (p = 0.002, p = 0.001, and p = 0.001, respectively). The Bax/Bcl-XL ratio was higher in JG than in IG animals (p = 0.011).

CONCLUSION

Adaptive responses seemed to be more effective in the ileum than in the jejunum.

International Latin American Survey on Pediatric Intestinal Failure Team

There is little data on the experience of managing pediatric Intestinal Failure (IF) in Latin America. This study aimed to identify and describe the current organization and practices of the IF teams in Latin America and the Caribbean. An online survey was sent to inquire about the existence of IF teams that managed children on home parenteral nutrition (HPN). Our questionnaire was based on a previously published European study with a similar goal. Twenty-four centers with pediatric IF teams in eight countries completed the survey, representing a total number of 316 children on HPN. The median number of children on parenteral nutrition (PN) at home per team was 5.5 (range 1-50). Teams consisted of the following members: pediatric gastroenterologist and a pediatric surgeon in all teams, dietician (95.8%), nurse (91.7%), social worker (79.2%), pharmacist (70.8%), oral therapist (62.5%), psychologist (58.3%), and physiotherapist (45.8%). The majority of the centers followed international standards of care on vascular access, parenteral and enteral nutrition, and IF medical and surgical management, but a significant percentage reported inability to monitor micronutrients, like vitamins A (37.5%), E (41.7%), B1 (66.7%), B2 (62.5%), B6 (62.5%), active B12 (58.3%); and trace elements-including zinc (29.2%), aluminum (75%), copper (37.5%), chromium (58.3%), selenium (58.3%), and manganese (58.3%). Conclusion: There is wide variation in how IF teams are structured in Latin America-while many countries have well-established Intestinal rehabilitation programs, a few do not follow international standards. Many countries did not report having an IF team managing pediatric patients on HPN.

Experiences with intestinal failure from an intestinal rehabilitation unit in a country without home parenteral nutrition

OBJECTIVE

For the first time, we reported experiences with an intestinal rehabilitation unit (IRU) from a country without home parenteral nutrition (HPN).

METHODS

We included patients with a diagnosis of intestinal failure (IF) since the establishment of our IRU from February 2018 to February 2020. We further report on our protocols for management of enterocutaneous fistulas (ECFs), short-bowel syndrome (SBS), chronic intestinal pseudo-obstruction and motility disorders.

RESULTS

Among a total of 349 patients who have been admitted, 100 patients had IF and were included . Mean (SD) age of patients was 46.3 ± 16.1 years. Most common cause of IF was ECFs (32%), SBS (24%), and SBS + fistula (22%). Most common causes of SBS were mesenteric ischemia (63.3%) and repeated surgery (22.4%). Median (interquartile range [IQR]) duration of parenteral nutrition (PN) for patients was 32 (18-60) days. The most common reconstructive surgery performed was resection and anastomosis (75.4%), followed by serial transverse enteroplasty procedure (10.5%) and closure of ostoma (7%). Patients were hospitalized for a median (IQR) of 33 (17.5-61) days. Most common complications were sepsis (45%), catheter infections (43%), and catheter thrombosis (20%), respectively. At the final follow-up, 61% stopped receiving PN, 23% became candidates for transplantation, and 16% died.

CONCLUSION

Considering that most countries lack facilities for HPN, by establishing IRUs using specific treatment protocols and autologous gastrointestinal reconstruction techniques will provide a means to manage patients with IF, thus decreasing death rates and number of patients who require intestinal transplantations due to IF.

NeoCHIRP: A model for intestinal rehabilitation in the neonatal intensive care unit

Multidisciplinary intestinal rehabilitation (IR) teams have transformed care in pediatric intestinal failure (IF).¹ Although most children with IF are identified in the neonatal intensive care unit (NICU), IR teams may not be involved at this stage. We describe our collaborative model, blending NICU and IR expertise to optimize care. Over 6 years, the NeoCHIRP (Neonatal Children's IR Program) team followed 164 babies for weekly visits (median, 8; range, 1-27). Bedside rounds included CHIRP team physician and surgeons, neonatologist champion, attending neonatologist and fellow, NICU dietitian, bedside nurse, and family. Medical and nutrition status, nutrition history, and laboratory data were discussed, and a nutrition plan to support IR, considering the child's other medical needs, was created to guide the next week's management. Typical issues addressed included parenteral nutrition (PN) composition, enteral nutrition plan, oral feeding, management of small-intestinal bacterial overgrowth and sodium status, and cholestasis. A total of 164 babies were followed by the NeoCHIRP team. Of 153 survivors, IF resolved by discharge in 89% (136 of 153). Seventeen of 153 babies (11%) went on to require home PN and were transferred from NICU directly to the CHIRP team. By discharge, 99% of babies were orally fed (69/136, 50% fully, 67/136, 49% partially), and cholestasis improved or resolved in 80/105 (76%). Eleven babies (7%) died; four deaths were unrelated to IF, but in seven babies, IF was at least a contributing factor. In this high-risk cohort, most babies achieved good outcomes, and those who required longer-term IR transitioned smoothly to the CHIRP team.

Physical Activity and Fatigue in Children With Intestinal Failure on Parenteral Nutrition

OBJECTIVES

With improved survival of children with intestinal failure (IF), it is important to examine the impact on long-term physical function, physical activity (PA), and fatigue and identify clinical factors that may be predictive of impairment.

METHODS

Cross-sectional study in children with IF on parenteral nutrition (PN) compared with healthy age- and sex-matched controls (HCs). Assessments included: Paediatric Quality of Life (PedsQL) Physical Function subscale, PedsQL Multi-Dimensional Fatigue Scale, and PA Perceived Benefits and Barriers scale. PA was measured using an accelerometer. Medical data was collected by chart abstraction.

RESULTS

Participants included 21 children with IF (14 girls), median age 8.33 (interquartile range [IQR] 6.96-11.04) years and 33 HCs (20 boys), 8.25 (6.67-10.79) years. In those with IF, 13 (62%) were born prematurely with a median of 15 (7.5-24.5) in-patient hospitalizations. There was a significant difference (P = 0.033) in mean steps/day in children with IF (9709 +/- 3975) compared with HCs (13104 +/- 5416), and a correlation between moderate-to-vigorous PA and gestational age (r = 0.642, P = 0.010). Child and parent proxy scores indicate poorer physical function and greater fatigue in the IF group, along with a correlation between greater fatigue (r = -0.538, P = 0.012), poorer physical function (r = -0.0650, P = 0.0001) in children with more hospitalizations. Barriers to PA include "I am tired" and "I am worried about my line."

CONCLUSIONS

Children with IF present with lower levels of PA and physical function and greater fatigue compared with their peers. Ongoing development of medical and rehabilitation intervention strategies is vital to optimize outcomes.

Teduglutide for pediatric short bowel syndrome patients

Introduction: The goal for pediatric short bowel syndrome (SBS) patients is intestinal adaptation. Until recently, the medical management of pediatric SBS has centered on the prevention and treatment of complications in order to allow time for adaptation. Teduglutide, glucagon-like peptide 2 (GLP-2) analog, has recently been approved for use in pediatric SBS patients greater than 1 year of age as a novel agent to augment intestinal adaptation. Areas covered: This article reviews the pharmacology, safety, efficacy, and tolerability of GLP-2 analog teduglutide in pediatric patients greater than 1 year of age. We review all current studies and discuss teduglutide's place in pediatric SBS therapy. Expert opinion: Teduglutide marks the first successful pharmacological intervention that augments the natural process of adaptation safely and effectively in SBS pediatric patients. More studies and further development are needed to optimize its potential in other pediatric patients.

Thirty percent ethanol locks ineffective in preventing central line-associated bloodstream infection in pediatric intestinal rehabilitation patients

BACKGROUND

Intestinal failure patients dependent on parental nutrition are reliant on central venous catheters and are at increased risk for central line-associated bloodstream infection (CLABSI). Seventy percent ethanol has been widely used for prophylaxis; however, it is known to have multiple adverse effects. This study demonstrates the implementation of a 30% ethanol lock protocol for CLABSI prevention in a community-based hospital intestinal rehabilitation program.

METHODS

This case series reports rates of CLABSI, compromised central venous catheter, and analysis of community bacterial pathogens.

RESULTS

A 42.1% increase in CLABSI and a 125% increase in compromised central venous catheters were noted after initiation of the 30% ethanol lock protocol.

CONCLUSION

It can be concluded that for the pediatric intestinal rehabilitation patient, 30% ethanol did not provide adequate CLABSI prophylaxis. This study indicates the need for larger sample sizes or the use of other concentrations of ethanol locks ranging between 30% and 70%.

Intestinal transplantation

PURPOSE OF REVIEW

Intestinal transplantation has evolved to be a viable treatment option for patients with intestinal failure. This review shows the most current tendencies and practices of intestinal transplant centers and an overall comparison to intestinal rehabilitation.

RECENT FINDINGS

This review outlines that timing for referral and advances in preoperative and postoperative care of intestinal and multivisceral transplant candidates are crucial to achieve results comparable to intestinal rehabilitation.

SUMMARY

Current practices have shown that intestinal transplantation continues to improve overall results and could be considered in patients with permanent home parenteral nutrition. Timing for referral and preoperative and postoperative management are crucial to optimize long-term results.

Twelve-year outcomes of intestinal failure-associated liver disease in children with short-bowel syndrome: 97% transplant-free survival and 81% enteral autonomy

Our aim was to analyze the outcomes in children with short-bowel syndrome (SBS), parenteral nutrition dependence (PND), and intestinal failure-associated liver disease (IFALD) treated in our Intestinal Rehabilitation Program (IRP) during 2007-2018. We retrospectively reviewed charts of 135 patients with SBS-PND at the time of enrollment in IRP; of these, 89 (66%) had IFALD, defined as conjugated bilirubin (CB) of ≥2 mg/dl at enrollment and/or abnormal liver biopsy showing stage 2-4 fibrosis. Outcomes included resolution of CB, enteral autonomy, laboratory parameters (platelets, aspartate aminotransferase to platelet ratio index), growth trends, transplant rates, and mortality. Of the 89 patients, 74 had elevated CB at enrollment; the other 15 had normalized CB but had fibrosis on liver biopsy. Thirty-eight patients had liver biopsies: 36 (95%) had fibrosis, including 21/36 with bridging fibrosis/cirrhosis. The median proportion of residual small bowel was 23% (interquartile range, 13%-38%) of the expected length for age and median, daily energy requirement by PN was 100%. Two received a transplant, three died (one posttransplant), and the remaining 85 survived; 69 (81%) achieved enteral autonomy. Seventy-three (99%) of the 74 patients with hyperbilirubinemia normalized their CB with medical treatment. In a subset of eight of 89 patients with initial platelet count of <100,000/μl(median 50,500/μl) and median CB of 21 mg/dl, seven achieved CB normalization and had improved platelet count. Overall survival was 97% (censored 96.3%). We demonstrate high transplant-free survival and enteral autonomy rates among children with SBS-IFALD relying on low-dose soybean lipid emulsion.

Effectiveness of a central line associated blood stream infection protocol in a pediatric population

BACKGROUND

Central line associated bloodstream infections are a common cause of bacteremia and sepsis in pediatric patients with intestinal failure, secondary to long-term CVC use.

METHODS

An IRB approved retrospective chart review was conducted on TPN-dependent patients with IF who had an identified CLABSI and presented to Children's of Alabama's emergency department (ED) and were admitted to the hospital.

RESULTS

Forty-four patients were included in the study, 28 in the first 18-month period and 26 in the second, with 10 in both populations. After implementation, mean time from ED presentation to antibiotic ordered and ED admission to antibiotic administered were lower. Mean time between antibiotic administration and admission to the floor was greater, and number of infectious disease consultations was greater. Floor-ICU transfers were lower, readmissions within 30 days was similar, and mean length of stay was similar.

CONCLUSION

A collaborative, multidiscipline-supported protocol for the care of patients with IF presenting to the ED enhances efficiency of antibiotic ordering/administration, as well as reduces the number of unplanned floor-ICU transfers.

Impact of central venous catheter repair in pediatric intestinal failure

OBJECTIVES

Patients with intestinal failure (IF) require long-term parenteral nutrition through central venous catheters (CVCs). When damaged, catheter replacement or repair is considered. Limited literature exists on repair outcomes in this population. We aimed to assess the impact of repair on durability of exiting CVCs and infection rates.

METHODS

This was a retrospective cohort study of pediatric IF patients with tunneled silicone CVCs over 10 years. Outcomes were evaluated by assessing CVC longevity, repair success, replacement, and postrepair infection rates.

RESULTS

One hundred thirty-eight repairs and 45 replacements were conducted in 37 patients with repair and replacement rates of 4.7 and 1.5 per 1000 catheter days, respectively. Twenty patients (54%) required ≥1 repair. For CVCs requiring repair, median CVC durability without and with repairs were at 123 and 391 days, respectively (P < .0001). Overall repair success rate was 96% with significantly lower success in the emergency department at 81% (P = .007). The 7-day postrepair infection rate was 2.2% without specific risk factors identified. Most repairs (76%) were performed by the Pediatric Gastroenterology division. Variability in practice was noted among services, including frequency of periprocedural antibiotic use and performance of temporary repairs before permanent repairs. A gradual increase in CVC repair rate was noted over time.

CONCLUSIONS

Our study showed that CVC repair is effective in prolonging CVC durability in pediatric IF patients without increasing infection rates. Incorporating a temporary repair as a step before permanent repair may offer a route to address potential intraluminal thrombosis before permanent repair.

European Pediatric Surgeon' Association Survey on the Management of Short-Bowel Syndrome

INTRODUCTION

 The aim of this study was to assess the management of short-bowel syndrome (SBS) at the time of primary surgery, and the strategies used to facilitate enteral autonomy depending on the institutional expertise.

MATERIALS AND METHODS

 An online questionnaire was sent in 2019 to members of The European Pediatric Surgeons' Association.

RESULTS

 Among the 65 responding members (26 countries, 85% from university hospitals), 57% manage less than three new patients with SBS per year (group A), and 43% at least three patients (group B). The cut-off of three patients treated yearly used in our study was defined after statistical analysis of different cut-offs. A multidisciplinary intestinal rehabilitation program is significantly more frequent in group B than in group A (85 and 53%, respectively; p = 0.009). Considering the primary surgical management of multiple intestinal atresia and congenital ultra-short bowel with jejunal atresia, primary surgical strategies to optimize bowel length are more often used in group B than group A (p = 0.09 and p = 0.04, respectively). A minimum of one intestinal lengthening procedure every 2 to 3 years is significantly more frequent in group B than group A (95 and 45%, respectively; p = 0.0013). Among the strategies used to promote intestinal adaptation, group B (35%) uses significantly more often glucagon-like peptide 2 analogs than group A (10%) (p = 0.02).

CONCLUSION

 Based on our survey, a minimum number of SBS patients treated yearly is required to manage this challenging disease according to up-to-date medical and surgical strategies. However, whatever their level of expertise is in managing SBS, most of pediatric surgeons are involved in the primary surgery. Medical education programs about SBS should be more largely available to pediatric surgeons.

Nutritional and pharmacological strategy in children with short bowel syndrome

Short bowel syndrome in neonates is a severe and life-threatening disease after a major loss of small bowel with or without large bowel. Intestinal adaptation, by which the organism tries to restore digestive and absorptive capacities, is entirely dependent on stimulation of the active enterocytes by enteral nutrition. This review summarizes recent knowledge about the pathophysiologic consequences after the loss of different intestinal parts and outlines the options for enteral nutrition and pharmacological therapies to support the adaptation process.

Current strategies for managing intestinal failure-associated liver disease

Introduction: Intestinal failure-associated liver disease (IFALD) refers to hepatic dysfunction that results from prolonged parenteral nutrition (PN) use. IFALD is multifactorial in origin and remains a major cause of morbidity and mortality. Prior to 2004, IFALD was associated with mortality as high as 90% in infants who remained on PN greater than 1 year. The advent of new strategies for intravenous lipid emulsion (ILE) administration and improved catheter care now allow many patients to remain on PN and recover from this once fatal condition. Several additional treatment modalities are often used to further improve outcomes for IFALD patients and they are reviewed here.Areas covered: The etiology of IFALD is presented, as well as the rationale behind the use of ILEs that contain fish oil. Other management strategies are addressed, including the effects of several pharmacologic and nutritional interventions.Expert opinion: Like its etiology, the management of IFALD is multifactorial. Prompt recognition of patients at risk, avoiding macronutrient excess, and preventing central line associated bloodstream infections will improve outcomes. In patients who develop IFALD, the use of fish oil monotherapy seems to be efficacious. The most effective intervention, however, continues to be discontinuation of PN and achieving full enteral feedings.

Secondary Anticoagulation Prophylaxis for Catheter-Related Thrombosis in Pediatric Intestinal Failure: Comparison of Short- Vs Long-Term Treatment Protocols

INTRODUCTION

Catheter-related thrombosis (CRT) is a devastating complication of central venous catheters in children with intestinal failure (IF), but the optimal preventive therapy of CRT is unknown. This study assessed the efficacy and safety of 2 protocols of secondary anticoagulation prophylaxis with low-molecular-weight heparin (LMWH).

METHODS

This is a comparative cohort study of children from 2 IF programs who received secondary anticoagulation prophylaxis with LMWH for CRT. The short-term protocol group (N = 13) received therapeutic dosing until thrombus resolution or ≤3 months. In the long-term protocol group (N = 26), prophylactic dosing continued until line removal. Patients underwent routine annual vascular ultrasound and were followed for ≥1 year. The primary outcome was development of secondary thrombosis; post hoc analysis assessed rates of secondary thrombosis at 12 months.

RESULTS

Patient demographics were similar between groups. Secondary thrombosis occurred in 8 of 13 (62%) patients in the short-term group and in 9 of 26 (35%) in the long-term protocol group (P = .019) in a median time of 144.5 and 689 days, respectively (P = .01). Secondary thrombosis within 12 months occurred in 7 of 13 (54%, short term) and 2 of 26 (8%, long term) patients (P = .001). Secondary thrombosis was associated with catheter replacements (23.5 vs 5.5 catheters per 1000 catheter days; P = .016) and longer daily parenteral nutrition (PN) infusion (24 vs 15.25 hours; P = .044). Compliance was good (>80% of doses) in 92% of patients.

CONCLUSIONS

Long-term secondary anticoagulation prophylaxis with LMWH reduces the incidence of secondary thrombosis and should be considered in children with CRT that require PN for prolonged periods of time.

Gastroesophageal Reflux Disease and Foregut Dysmotility in Children with Intestinal Failure

Gastrointestinal dysmotility is a common problem in a subgroup of children with intestinal failure (IF), including short bowel syndrome (SBS) and pediatric intestinal pseudo-obstruction (PIPO). It contributes significantly to the increased morbidity and decreased quality of life in this patient population. Impaired gastrointestinal (GI) motility in IF arises from either loss of GI function due to the primary disorder (e.g., neuropathic or myopathic disorder in the PIPO syndrome) and/or a critical reduction in gut mass. Abnormalities of the anatomy, enteric hormone secretion and neural supply in IF can result in rapid transit, ineffective antegrade peristalsis, delayed gastric emptying or gastroesophageal reflux. Understanding the underlying pathophysiologic mechanism(s) of the enteric dysmotility in IF helps us to plan an appropriate diagnostic workup and apply individually tailored nutritional and pharmacological management, which might ultimately lead to an overall improvement in the quality of life and increase in enteral tolerance. In this review, we have focused on the pathogenesis of GI dysmotility in children with IF, as well as the management and treatment options.

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.

National Survey of Pediatric Intestinal Rehabilitation Programs in the United States

BACKGROUND

Pediatric intestinal rehabilitation (PIR) programs are associated with improved outcomes in children with intestinal failure but remain heterogeneous nationally. This study characterizes PIR program components to aid those seeking to establish or expand a program.

METHODS

Members of the Children's Hospital Association reporting a PIR program to the US News and World Report completed a 14-item questionnaire using the Qualtrics Online Survey Software. Programs were categorized as small or large (≤50 vs >50 patients) and new or established (≤10 vs >10 years).

RESULTS

Seventy-one programs were identified and 61 surveys were returned for a response rate of 86%. Majority of programs had gastroenterology, surgery, nutrition, nursing, and social work services involved. Large programs (n = 34; 59%) were more likely to serve as referral centers; have greater participation by nursing, social work, and primary care; have more dedicated time by gastroenterology, surgery, nursing, nutrition, and social work; have more frequent meetings; and have various funding sources (P < .05).

CONCLUSION

Critical components of a PIR program include gastroenterology, surgery, and nutrition services with strong nursing and social work support. These data document the components of modern PIR programs, though further studies on the relationship between program structure and patient outcomes are warranted.

To Wean or Not to Wean: The Role of Autologous Reconstructive Surgery in the Natural History of Pediatric Short Bowel Syndrome on Behalf of Italian Society for Gastroenterology, Hepatology and Nutrition (SIGENP)

Pediatric Short Bowel Syndrome (SBS) can require prolonged parenteral nutrition (PN). Over the years, SBS management has been implemented by autologous gastrointestinal reconstructive surgery (AGIR). The primary objective of the present review was to assess the effect of AGIR on weaning off PN. We also evaluated how AGIR impacts survival, the need for transplantation (Tx) and the development of liver disease (LD). We conducted a systematic literature search to identify studies published from January 1999 to the present and 947 patients were identified. PN alone was weakly associated with higher probability of weaning from PN (OR = 1.1, p = 0.03) and of surviving (OR = 1.05, p = 0.01). Adjusting for age, the probability of weaning off PN but of not surviving remained significantly associated with PN alone (OR = 1.08, p = 0.03). Finally, adjusting for age and primary diagnosis (gastroschisis), any association was lost. The prevalence of TX and LD did not differ by groups. In conclusion, in view of the low benefit in terms of intestinal adaptation and of the not negligible rate of complications (20%), a careful selection of candidates for AGIR should be required. Bowel dilation associated with failure of advancing EN and poor growth, should be criteria to refer for AGIR.

Short Bowel Syndrome in an Infant

Short bowel syndrome (SBS) is a malabsorptive state that may occur either after surgical bowel resection or as the result of congenital bowel anomalies. SBS can incur significant morbidity and mortality including intestinal failure, cholestasis, sepsis, and death. For patients with SBS, management involves a multidisciplinary approach that begins with neonatology, pediatric surgery, nutritionists, pharmacists, and nurses in the NICU and also includes the transition to an intestinal rehabilitation program. The aim of this review is to provide the neonatologist with an overview of the common causes of neonatal SBS, anticipated nutritional deficiencies, complications associated with SBS, and the surgical and medical management of SBS to assist in counseling affected families.

Intestinal Failure: A Description of the Problem and Recent Therapeutic Advances

Pediatric intestinal failure occurs when gut function is insufficient to meet the nutrient and hydration needs of the growing child. The commonest cause is short bowel syndrome with maldigestion and malabsorption following massive bowel loss. The remnant bowel adapts during the process of intestinal rehabilitation. Management promotes the achievement of enteral autonomy while mitigating the risk of comorbid disease. The future of care is likely to see expansion of pharmacologic methods for augmenting bowel adaptation, tissue engineering techniques enabling immune suppression-free autologous bowel transplant, and the development of electronic health record tools for efficient, collaborative study and care improvement.

Comparing the Intestinotrophic Effects of 2 Glucagon-Like Peptide-2 Analogues in the Treatment of Short-Bowel Syndrome in Neonatal Piglets

BACKGROUND

In treating short-bowel syndrome (SBS), autonomy from parenteral nutrition (PN) relies upon intestinal adaptation, which can be augmented by glucagon-like peptide-2 (GLP-2) analogues. In neonatal piglets with SBS, we compared intestinal adaptation following treatment with 2 GLP-2 analogues: teduglutide (TED) and apraglutide (APRA) METHODS: Following 75% distal small-intestinal resection, piglets were allocated to 4 treatment groups: saline (CON: n = 8), twice weekly APRA (5 mg/kg/dose; n = 8), and TED once daily (TED, 0.05 mg/kg/dose; n = 8) or twice daily (TEDBID, 0.05 mg/kg/dose; n = 7). Pharmacokinetic (PK) studies were undertaken, and on day 7, small-intestinal length and weight were measured and jejunal tissue collected for histology.

RESULTS

PK profiles were different between the 2 analogues. To achieve a comparable exposure to APRA, TED requires twice daily injection (TEDBID). Compared with CON, APRA and TEDBID increased small-bowel length (cm) (CON: 141, APRA: 166, TED: 153, TEDBID: 165; P = .004), whereas APRA increased small-bowel weight (g) (CON: 26, APRA: 33, TED: 28, TEDBID: 31; P = .007) and villus height (mm) (CON: 0.59, APRA: 0.90, TED: 0.58, TEDBID: 0.74; P < .001).

CONCLUSION

APRA injected only twice during the 7 consecutive days demonstrated a superior intestinotrophic effect compared with TED injected once daily. Even at more comparable drug exposure, when TED was injected twice a day, APRA showed superior trophic activity at the mucosal level. This is highly relevant for the treatment of pediatric SBS, given the markedly lower dose frequency by subcutaneous injection of APRA.
