Approach to Intestinal Failure in Children

Associations between hospital-level socioeconomic patient mix and rates of central line-associated bloodstream infections in short bowel syndrome: A retrospective cohort study

BACKGROUND

Low neighborhood income is linked with increased hospitalizations for central line-associated bloodstream infections (CLABSIs) in pediatric short bowel syndrome (SBS). We assessed whether this relationship varies by hospital center.

METHODS

We performed a retrospective cohort study using the Pediatric Health Information System (2018-2023) database for patients <18 years old with SBS (N = 1210) at 24 hospitals in the United States. Using 2015 US Census data, we determined the estimated median household income of each patient's zip code. Hospital-level neighborhood income was defined as the median of the estimated median household income among patients at each hospital. We applied an extension of Cox regression to assess risk for CLABSI hospitalization.

RESULTS

Among 1210 children with 5255 hospitalizations, most were <1 year on initial admission (53%), male (58%), and publicly insured (69%). Hospitals serving low-income neighborhoods served more female (46% vs 39%), Black (29% vs 22%), and Hispanic (22% vs 16%) patients with public insurance (72% vs 65%) residing in the southern United States (47% vs 21%). In univariate analysis, low hospital-level neighborhood income was associated with increased risk of CLABSI hospitalization (rate ratio [RR], 1.48; 95% CI, 1.21-1.83; P < 0.001). These findings persisted in multivariate analysis (RR, 1.43; 95% CI, 1.10-1.84; P < 0.01) after adjusting for race, ethnicity, insurance, region, and patient-level neighborhood income.

CONCLUSION

Hospitals serving predominantly low-income neighborhoods bear a heavier burden of CLABSI hospitalizations for all their patients across the socioeconomic spectrum. Hospital initiatives focused on CLABSI prevention may be pivotal in addressing this disparity.

Comparison of two formulations of intravenous lipid emulsions in pediatric intestinal failure

PURPOSE

The effect of different types of lipid emulsion may guide therapy of patients with intestinal failure (IF) to limit morbidity such as intestinal failure-associated liver disease (IFALD).

METHODS

A retrospective chart review of pediatric patients with IF who received soybean oil lipid emulsion (SL) or mixed oil lipid emulsion (ML) was performed. Data over 1 year were collected.

RESULTS

Forty-five patients received SL and 34 received ML. There were no differences in the incidence (82 versus 74%, P = 0.35) or resolution (86 versus 92%, P = 0.5) of IFALD between the cohorts. The median dose of ML was higher compared to SL (2 versus 1 g/kg/day, P < 0.001). If resolved, IFALD resolved rapidly in the ML cohort compared to the SL cohort (67 versus 37 days, P = 0.01). Weight gain was higher in the ML compared to the SL cohort at resolution of IFALD or 1 year from diagnosis of IF (P = 0.009).

CONCLUSION

The administration of ML did not alter the incidence or resolution of IFALD compared to SL in pediatric IF. There was rapid resolution of IFALD and enhanced weight gain in the ML cohort compared to SL in pediatric IF.

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.

Teduglutide in pediatric intestinal failure: A position statement of the Italian society of pediatric gastroenterology, hepatology and nutrition (SIGENP)

In recent years, the spectrum of possible treatments for Intestinal Failure (IF)-Short Bowel Syndrome (SBS) has been enriched by the implementation of GLP-2 analogues. In Italy, teduglutide (Ted), an analogue of GLP-2, was approved in January 2021 by the Italian Regulatory Agency for Drugs (AIFA) for IF-SBS patients ≥1 year old. According to the Agency indications, Ted can now be prescribed by regional reference centers, with costs fully charged to the National Health Service. Following pediatric-use approval in our country and in light of scarce evidence in childhood, the pediatric network for IF of the Italian Society for Pediatric Gastroenterology, Hepatology and Nutrition (SIGENP) planned to share management methods of Ted in pediatric IF. The main purpose was to identify the best candidates from a cost-effective perspective. Thus, focusing on available literature and on expert opinions, the present position statement provides consensus-based recommendations on the use of Ted for pediatric gastroenterologists and nutritionists treating children with SBS.

25 Years of a Standardized Technique for Living Donor Intestinal Transplantation: A Systematic Review

A safe, reproducible and standardized surgical technique for intestinal procurement and transplantation from a living donor (LD) was introduced in 1997 and has been used in the majority of cases since. The key principles are: 1. procurement of 180-200 cm of distal ileum in adults (about 60-150 cm in pediatric recipients depending on age and weight) on a vascular pedicle comprising the LD ileocolic vessels or terminal branches of the superior mesenteric vessels, 2. the terminal ileum (30-40 cm of the most distal ileum), the ileocecal valve and the cecum remain with the donor to not interfere with B12-absorption and bowel transit time, 3. systemic venous drainage with anastomoses between the LD ileocolic vessels and the recipient's infrarenal aorta and vena cava, and 4. restoration of recipient bowel continuity through proximal anastomosis and distal graft ileostomy for biopsy access and graft monitoring. Recipients of a successful LD intestinal transplant become total parenteral nutrition (TPN)-independent within a few weeks posttransplant. LD vs deceased donor (DD) intestinal transplants can be performed in a more timely fashion. Hence, LD (in contrast to DD) intestinal transplants are also pre-emptive procedures in patients with advanced, but still reversible, TPN-induced liver disease and help reduce the wait-list mortality for combined DD intestinal and liver transplants. Life-saving combined LD intestinal and liver transplants, albeit rare, have also been successfully performed either simultaneously or subsequently. There have been no reported deaths or major complications of living intestinal donors. A better metabolic profile has been reported in some donors post-donation. In total, 85 documented LD intestinal transplants have been performed worldwide at over 20 different transplant centers in 12 different countries. In about 70 transplants, the standardized technique was used. There has been no difference in outcome between LD vs DD intestinal transplants. Long-term studies have shown that > 10 year of graft function is not uncommon. Since the introduction of the standardized surgical technique, LD intestinal transplantation has evolved from an experimental to an established and standardized procedure.

Neonatal Cholestasis: Updates on Diagnostics, Therapeutics, and Prevention

Cholestatic jaundice is a common presenting feature of hepatobiliary and/or metabolic dysfunction in the newborn and young infant. Timely detection of cholestasis, followed by rapid step-wise evaluation to determine the etiology, is crucial to identify those causes that are amenable to medical or surgical intervention and to optimize outcomes for all infants. In the past 2 decades, genetic etiologies have been elucidated for many cholestatic diseases, and next-generation sequencing, whole-exome sequencing, and whole-genome sequencing now allow for relatively rapid and cost-effective diagnosis of conditions not previously identifiable via standard blood tests and/or liver biopsy. Advances have also been made in our understanding of risk factors for parenteral nutrition-associated cholestasis/liver disease. New lipid emulsion formulations, coupled with preventive measures to decrease central line-associated bloodstream infections, have resulted in lower rates of cholestasis and liver disease in infants and children receiving long-term parental nutrition. Unfortunately, little progress has been made in determining the exact cause of biliary atresia. The median age at the time of the hepatoportoenterostomy procedure is still greater than 60 days; consequently, biliary atresia remains the primary indication for pediatric liver transplantation. Several emerging therapies may reduce the bile acid load to the liver and improve outcomes in some neonatal cholestatic disorders. The goal of this article is to review the etiologies, diagnostic algorithms, and current and future management strategies for infants with cholestasis.
