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

Body Composition and Physical Activity in Pediatric Intestinal Failure On and Off Parenteral Nutrition

OBJECTIVES

Data on the relationship between body composition (BC) and physical activity (PA) in children with intestinal failure (IF) are lacking. The objectives were to collect data on PA and BC in children with IF, both parenterally and enterally fed, and to assess the relationship between PA and BC.

METHODS

Cross-sectional study in children 5-18 years with IF including those receiving parenteral nutrition (PN) and those fully enterally fed. PA levels were measured using accelerometry. BC was measured by dual-energy X-ray absorptiometry. Data were compared to age- and sex-matched population norms using t tests. Regression analysis assessed the relationship between BC and PA.

RESULTS

Fifty-eight children with IF (38 males), mean (SD) age of 10.0 (3.5) years, 20 dependent on PN were included. Patients with IF had significantly fewer steps per day ( P ≤ 0.001) compared with literature controls, with a mean (SD) of 7,972 (3,008) and 11,749 (1,106), respectively. There were no significant differences between patients receiving PN and those enterally fed, but both groups were significantly less active than literature controls ( P < 0.001). Patients with IF had higher fat mass and lower fat-free mass compared to literature controls ( P = 0.008). PA had a significant effect on BC ( r2 = 0.32, P < 0.001).

CONCLUSIONS

Children with IF, those receiving PN and those fully enterally fed, are at risk of decreased PA and altered BC. PA should be part of ongoing rehabilitation and management to optimize outcomes.

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.

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.

Overview of Physical, Neurocognitive, and Psychosocial Outcomes in Pediatric Intestinal Failure and Transplantation

PURPOSE OF REVIEW

Intestinal failure and transplantation may significantly impact physical, neurocognitive, and psychosocial development in pediatric patients. Currently, there is a paucity of literature on the effects of intestinal failure and transplantation on these aspects of development. This article will review the current literature and discuss the short and long-term impacts as well as interventions to improve clinical outcomes in children with intestinal failure or those undergoing transplantation.

RECENT FINDINGS

Psychological disorders, neurodevelopmental delay, and social maladaptation are frequently encountered in this patient population. While the main focus is often on medical management, equal emphasis should be placed on other aspects of development such as increasing social support and improving school performance. The transition to adulthood also presents many obstacles for patients and healthcare providers should anticipate challenges such as childbirth, employment, and raising a family. The pre-operative, perioperative, and post-operative periods all represent opportunities for medical intervention. Frequent monitoring of physical, psychosocial, and neurocognitive status helps to improve clinical outcomes and long-term quality of life. Future research should emphasize continued development of multidisciplinary programs and specialized services to help address the physical and psychosocial needs of children with intestinal failure as well as transplant recipients.

Physical activity in inflammatory bowel disease: benefits, challenges and perspectives

PURPOSE OF THE REVIEW

Physical activity is gaining significative interest in the field of inflammatory bowel disease (IBD). In the light of the most recent publications, the present review aims to describe the level of physical activity in adult patients with IBD; describe the current body of evidence on the benefits of physical activity and discuss the challenges and perspectives related to physical activity in this population.

RECENT FINDINGS

Recent studies showed that IBD patients tend to be less active than healthy people. There is growing evidence of a positive impact of physical activity on mortality, quality of life, fatigue, body composition, strength and physical performance. The direct benefits of physical activity on clinical remission and disease activity have recently been observed only in Crohn's disease. Limitations to physical activity related to the disease, such as gastrointestinal and psychological symptoms, need to be considered in this population. Finally, no guidelines are available and there is no evidence regarding the effects of combined physical activity and nutritional support.

SUMMARY

Although physical activity seems beneficial and safe for IBD patients, future studies are needed to clearly define recommendations in this population.

Longitudinal Development of Health-related Quality of Life and Fatigue in Children on Home Parenteral Nutrition

OBJECTIVES

The aim of the study was to describe the longitudinal development of health-related quality of life (HRQOL) and fatigue in children with chronic intestinal failure (CIF) on home parenteral nutrition (PN) and compare these children to the general population.

METHODS

Prospective, observational study conducted over 7 years in patients suffering from CIF receiving home PN from 2 tertiary hospitals in the Netherlands. Every 6 months, parents (if child <8 years old) or patients (if child ≥8 years old) completed 2 questionnaires: Pediatric Quality of Life Inventory 4.0 (PedsQL) Generic and Fatigue on the KLIK (kwaliteit van leven in kaart [Dutch Acronym for Quality of Life in Clinical Practice]) Patient Reported Outcome Measures portal, which were compared with the general population. Linear mixed models (LMMs) were constructed to investigate the course of HRQOL over time.

RESULTS

Thirty-five patients were included (40% girls). At time of last KLIK contact, patients received HPN for a median of 5.3 years (interquartile range [IQR]: 2.9-9.7). In total, 272 questionnaires were completed. PedsQL generic total score for ages 5 to 7 and 8 to 12 years was significantly lower than the general population (P < 0.01 for both age groups) with effect sizes of 0.73 and 0.71, respectively. PedsQL fatigue total score for ages 5 to 7 years was also significantly lower (P = 0.01; effect size 0.70). LMMs for PedsQL Generic and Fatigue total score 2 to 7 and 8 to 18 years showed no significant coefficient for duration of home PN.

CONCLUSIONS

Children suffering from CIF receiving home PN ages 5 to 12 years report lower HRQOL scores than the general population. HRQOL and fatigue do not change during long-term treatment with home PN in these children.

Normal anthropometry does not equal normal body composition in pediatric intestinal failure

BACKGROUND

Published reports on abnormal body composition in pediatric patients with intestinal failure have been in patients with poor growth. The goal of the current study is to report the body composition of normally growing patients with intestinal failure.

METHODS

Children 8-18 years old with a dual-energy x-ray absorptiometry (DXA) between January 1, 2013, and July 15, 2018, were included in the study. Data were retrospectively collected from the medical charts and included demographics, residual bowel anatomy, nutrition support, height, and weight. DXA data, including total body less head bone mineral density (BMD), fat mass (FM), and fat-free mass (FFM), were collected and compared with published literature controls matched for age and sex.

RESULTS

Thirty-four children met inclusion criteria. Mean age at the time of DXA was 9.6 ± 1.8 years. Weight- and height-for-age z-scores were -0.4 ± 0.9 and -0.5 ± 1.0, respectively. Mean BMD z-score was -1.0 ± 1.3. Twenty-six percent of patients (n = 9) had reduced BMD. Patients with intestinal failure had higher FM (P = .02) and lower FFM (P = .02) compared with controls.

CONCLUSIONS

These data show that, despite reference range z-scores for height and weight, children with intestinal failure are at risk for abnormal body composition. Body composition should be routinely measured in children with intestinal failure to direct nutrition interventions.
