Post-Endoscopic Fever in Pediatric Intestinal Failure & Short Bowel Syndrome Patients

Posted on by

J Hilberath et al. J Pediatr Gastroenterol Nutr. 2025;81:736–742. Open Access! Post‐endoscopic fever and infection in paediatricpatients with intestinal failure

Methods: This was a retrospective single-center observational study which included children with IF and CVC who underwent GI endoscopy between 2019 and 2024. Intravenous antibiotic prophylaxis was used in 71.2% of the procedures.

Key findings:

  • The overall post-endoscopic fever (PEF) rate was 6%, with no significant difference between the group that received prophylactic antibiotics and the group that did not. Specifically, there were 10 with PEF that had received prophylactic antibiotics and 4 that had PEF with no prophylaxis
  • No infections, including central line-associated bloodstream infections, were observed
  • 5/14 of the cases with PEF had an interventional procedure. The remainder had a diagnostic EGD, colonoscopy or both.

Interventional Cases:

Discussion Points:

  • “PEF in children with IF was 6%, which is approximately 10 times higher than the recently published 0.55% in pediatric patients following endoscopic procedures by Boster et al.” (see: Must-Read: How to Handle Post-Procedure Fevers)
  • A strength of this study was that the comparison of children with IV antibiotics versus those without was due to an institutional policy change in 2022. This helps eliminate selection bias in the determination that IV antibiotics were not beneficial in preventing PEF

My take: The high rate (6%) of PEF should be discussed with families prior to endoscopic procedures. The rate was increased (36%) in those with interventional procedures. It is reassuring that no definitive infections were identified despite the fevers.

Happy New Year!

——-

A Fialdowski et al. J Pediatr 2024; 275: 114226. Achieving Enteral Autonomy in Children with Intestinal Failure Following Inpatient Admission: A Case Series

This retrospective review identified 6 patients (out of 153) who were weaned off parenteral nutrition (PN) as part of an inpatient admission.

Key findings:

  • Except for one admission of 8 days, all of these patients required a prolonged admission 1-5 months.
  • Two of the patients were receiving PN primarily due to abdominal pain in the absence of a recognizable motility disorder.
  • Two of the patients had a suspected factitious disorder imposed on a medical disorder; one received this diagnosis.
  • All patients had chronic feeding intolerance despite favorable prognostic factors including underlying necrotizing enterocolitis (n=1), preserved ileocecal valve (n=5), longer bowel length (n=5), and retention of entire colon (n=5).
  • Post-pyloric feeds aided conversion to EN in 5 patients.

My take: In order to achieve enteral autonomy, hospital admission may be needed for patients who require long-term PN despite favorable prognostic factors.

  • Be prepared for a lengthy stay
  • Anticipate the need for an interdisciplinary team (eg. nutrition, social work, and others).

Short Bowel Syndrome and Risk of Eosinophilic Disease

Posted on by

N Du, C Torres. JPGN 2024;78:1149–1154. Prevalence of eosinophilic gastrointestinal diseases in children with short bowel syndrome: A single center study

Methods: EoEdefined as ≥15 eosinophils per high powered field (HPF), eosinophilic gastritis (EoG) as ≥30 eosinophils per HPF, eosinophilic enteritis (EoGN) as >50 eosinophils per HPF, and eosinophilic colitis (EoC) as>80–100 eosinophils per HPF.

Key findings in this retrospective study (n=82):

  • The prevalence of eosinophilic esophagitis in our SBS cohort was10%, eosinophilic gastritis was 4.9%, and eosinophilic enteritis was 4.9%
  • SBS patients with history of allergy or atopy were more likely to have esophageal and intestinal eosinophilia on biopsy than patients without allergy
  • One patient had EoC

In their discussion, the authors speculate on the potential role for dysbiosis, possibly related to parenteral nutrition. They note that “rare SBS patients were on amino acid‐based formulas alone and almost all were exposed to food allergens around the same age as the general population.” I did not see any information about PPI use in this cohort.

My take: This report reinforces the fact that eosinophilic disorders are more frequent in SBS (see related post below). The exact role of altered diet/use of amino acid based formulas and the role of medications like PPIs in regards to the development of EGIDs remains unclear.

Teduglutide-Induced Polyps

Posted on by

J Salazar et al. JPGN Reports 4(4):p e389. Open Access! Gastric Foveolar Hyperplastic Polyps in 2 Children With Short Bowel Syndrome on Long-Term Teduglutide

I have not been an enthusiastic early adopter of teduglutide. Though it has been shown to reduce HAL volumes in those with short bowel syndrome (SBS), this tends to revert with cessation of treatment. In addition, it has a very high cost and long-term adverse effects are unclear. Currently the manufacturer recommends a colonoscopy after 1 year of treatment.

This case report by Salazar et al identified two children who developed foveolar hyperplastic gastric polyps after receiving teduglutide.

Discussion points:

  • “There have been increasing reports of both benign and malignant small bowel polyp development. In trials of pediatric patients, limited to 12 and 24 weeks, initial upper endoscopy and colonoscopies were not required. In addition, postexposure upper endoscopy and colonoscopy was not the standard of care (9,13,16). Thus, the incidence of intestinal polyp formation on teduglutide treatment in pediatric patients remains unknown.”
  • “A recent retrospective review of adult patients with SBS showed increased small bowel polyp formation in 8 out of 35 patients (22.9%) on long-term teduglutide use… 3 were identified as adenomas with low-grade dysplasia… (14)”
  • “In general, isolated foveolar hyperplasia has not been identified as a premalignant lesion…The connection between foveolar hyperplasia and development of dysplasia, though, remains poorly understood, and further work delineating the natural history of foveolar polyps in the context of teduglutide is important.”

Related article: A Fifi et al. JPGN 2023; 77: 666-671. This is a post-hoc analysis showing improving stool consistency in 101 patients treated in open-label studies. Patients had mean drop of 20 mL/kg/day in parental fluid volume (compared to 7 mL/kg/day in the standard care treatment group).

My take: This case report indicates that endoscopic monitoring (possibly both upper endoscopy and colonoscopy) is needed in teduglutide-exposed patients. In addition, careful consent of the patients is prudent indicating the uncertain long-term effects. Finally, it would be a good idea to enroll all patients in a registry as well.

Thrombosis in Pediatric Patients with Intestinal Failure

Posted on by

G Keefe et al. J Pediatr 2023; 253: 152-157. High Rate of Venous Thromboembolism in Severe Pediatric Intestinal Failure

This retrospective study (n=263) examined the rate of venous thromboembolism (VTE) in pediatric patients who required parenteral nutrition for at least 90 consecutive days.

Key findings:

  • The cumulative incidence of VTE was 28.1%, with a rate of 0.32 VTEs per 1000 catheter-days
  • The number of catheters and early gestational age were noted to be independent risk factors for VTE
  • No patients had progression of thrombus while receiving therapeutic anticoagulation
  • Of those with acute DVTs (n=47), 24 (51%)resolved on repeat imaging, 14 (30%)were stable, and and 9 (19%) had decreased
  • 4.4% (2 of 45) had a major bleed while on anticoagulation

The authors note that the true rate of VTE is likely even higher because only 42% categorized as not having a VTE had undergone dedicated venous imaging.

My take: A lot of patients with intestinal failure develop VTE. Given the risks of treatment, the role of prophylactic anticoagulation remains unclear. This is where a prospective study would be helpful.

Short Bowel Syndrome is a Full Time Job

Posted on by

C Belza et al. J Pediatr 2022; 250: 75-82. Carrying the Burden: Informal Care Requirements by Caregivers of Children with Intestinal Failure Receiving Home Parenteral Nutrition

This was a cross-sectional study of caregivers of children (n=34) with intestinal failure receiving long-term parenteral nutrition. 97% of caregivers were the child’s mother and median duration of providing care among respondents was 3.4 years.

Key findings:

  • Caregivers reported a median of 29.2 hours per week (IQR, 20.8-45.7 hours per week) of direct medical care. 6.1 hours was spent on providing PN and care of the central venous catheter. 6.3 hours was spent on enteral nutrition and enteral tube care.

In the associated editorial (pgs 10-12 by S Mauskar, JG Berry. Open Access! “Failing to Support Families’ Burden of Care for Children with Intestinal Failure“), the authors note that in the U.S. there has been a growing population of children at home with greater medical complexity and reliance on medical technology and that the need for home nursing support “greatly exceeds the supply, leaving many families on their own to care for their children.”

They also note that the medical literature (over the last 25 years) on caregiver burden for children notes it is associated with “marital discord, loss of employment, and financial struggle…In the U.S. a substantial portion of children with medical complexity assisted with technology live in single-parent households, in poverty, and are exposed to adverse childhood events…very vulnerable to the effects of high caregiving burden.”

My take: This study shows that while we have an effective treatment for intestinal failure, the burden of this treatment is very high even with care coordination and social worker help. Understanding this burden could help medical providers be more empathetic for the family who is struggling with home medical care (eg. child with recurrent admissions for central line infections).

Will a SQUIRT Score Be Helpful?

Posted on by

A recent letter to the editor: J Rauh et al. Stool Quality for Intestinal Rehabilitation Therapy (SQUIRT) Score, JPS 2022. doi: https://doi.org/10.1016/j.jpedsurg.2022.08.025

The authors have devised a SQUIRT score for short bowel syndrome. The higher score indicates better enteral tolerance with a highest score of 13 and a lowest score is 3. It is a composite score based on composition, frequency and volume/blowouts. The authors define a blow-out to be a stool loose enough and large enough for the child to require a change of clothes.

How to Score:

Consistency (choose best stool of the day)
Playdough, Formed 5
Peanut Butter, Pasty 4
Pudding, Seedy 3
Pea Soup, Loose 2
Water 1

Occurrences (over 24 hours)
1 to 3 4
4 to 6 3
7 to 9 2
Greater Than 10 1
Ostomy Present 0

Volume
With Ostomy Without Ostomy
(mL/kg) (# of blowouts)

  • < 10 mL/kg 8 0 =4
  • 10 -14 mL/kg 7
    15-19 mL/kg 6 1 =3
  • 20-24 mL/kg 5 2 =2
    25-29 mL/kg 4
  • 30-34 mL/kg 3
  • 35 mL/kg 2
  • >35 mL/kg 1 >3 =1

The authors state that this scoring system has been used in their institution. “This tool can provide objective information to guide clinical decision making. Even patients with ostomies, for whom we can measure stool volume, benefit from SQUIRT scores because including the variable of stool consistency provides a more nuanced assessment than relying on volume.”

My take:This type of scoring system would be useful, primarily in patients in which the volume of stool is difficult to measure. It would benefit from trials to validate its utility.

Predicting Intestinal Failure After Gastroschisis Repair

Posted on by

N Vinit et al. J Pediatr 2022; DOI:https://doi.org/10.1016/j.jpeds.2021.11.004 (Ahead of print) Predicting Factors of Protracted Intestinal Failure in Children with Gastroschisis

Methods: Retrospective study. Among 180 patients, 35 required long-term parenteral nutrition (SBS-IF group) and 145 acquired full oral feeding within 6 months (oral feeding group) over mean f/u of 7.9 years.

Key findings:

  • Both bowel matting (OR, 14.2, P = .039) and secondarily diagnosed atresia or stenosis (OR, 17.78, P = .001) were independent postnatal predictors of SBS-IF.
  • An initial residual small bowel length of more than 50 cm was the best predictive cut-off for nutritional autonomy, with a sensitivity of 67% and a specificity of 100%

My take: This study identifies bowel matting and atresia/stenosis as additional factors in predicting nutritional autonomy.

Neurocognitive Function with Pediatric Intestinal Failure

Posted on by

Lately, there have been a lot of articles on neurocognitive function.  The latest (A Gold et al. JPGN 2020; 70: 225-31) describes the myriad of problems facing children with intestinal failure (IF). The authors literally used 12 different measures of neurocognitive and academic measures –though not all 28 subjects had each of these measures (Table 2).

Caveats:

  • The authors specifically excluded 5 children with severe neurodevelopmental problems that precluded participation in standardized assessment and 10 children who were transplant recipients.
  • Also, when judging the results, it is important to keep in mind that their cohort had a good maternal education level; 68% were college graduates.

Key findings:

  • 13 of 28 (46%) received a diagnosis of cognitive/learning DSM diagnosis
  • 29% met diagnostic criteria for a learning disability, 7% for ADHD, and 11% for intellectual disability; comparison Canadian prevalence rates are 4%, 5%, and 1% respectively
  • The number of first-year septic episodes was associated with poorer outcomes; ≥2 or more episodes increased the likelihood.
  • Sustained cholestasis was associated with poor outcomes
  • The average level of intellectual functioning in their sample of 28 children was within 1 standard deviation of the population mean

There are a lot of risk factors for neurodevelopment impairment in these children with IF: prematurity, nutritional status/specific nutrient deficiencies, cholestasis, need for anesthesia/surgeries

My take: More than half of children with IF had neurodevelopemental impairment.  In this cohort, recurrent sepsis in the first year of life and sustained cholestasis were associated risk factors.

John Kerner  Potential Role of New Fat Emulsions

Key points:

  • Both SMOFlipid and Omegaven help prevent and/or treat parenteral nutrition associated cholestasis.
  • SMOFlipid is much less expensive (see slide below) -50 gm of SMOFlipid ~$5 compared to 10 gm of Omegaven at $35, thus omegaven costs more than 30 times SMOFlipid.
  • Though SMOFlipid is not FDA approved in children, it is being used widely and allows for increased calories compared to lipid minimization with intralipid and could improve neurocognitive outcomes.
  • SMOF dosing (listed below) with goal of 3 g/kg in preterm infants.
  • Resolution of cholestasis does not mean reversal of cirrhosis.  Thus, lipid emulsion intervention at earlier stage may be important.

Bram Raphael  Getting In Line: Towards a Clinical Practice Guideline For CVC Salvage

Key points:

  • Several infections are very difficult to clear, especially yeast, enterococcus, and pseudomonas
  • Salvaging central lines may obviate the need for multi-visceral transplant which carries a 5-year ~50% mortality rate
  • Cefepime provides good gram-negative coverage; consider meropenem in those with septic shock
