Outcome and quality of life in paediatric home parenteral nutrition

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

BACKGROUND AND AIMS

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

PATIENTS AND METHODS

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

RESULTS

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

CONCLUSION

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

Health-related quality of life, anxiety, depression and distress of mothers and fathers of children on Home parenteral nutrition

BACKGROUND & AIMS

Parents of children with intestinal failure, dependent on Home Parenteral Nutrition (HPN), may experience psychosocial problems due to the illness and intensive treatment of their child. Literature concerning psychosocial problems is scarce. Therefore, we aimed to investigate Health-Related Quality of Life (HRQOL), levels of anxiety, depression, distress and everyday problems of these mothers and fathers.

METHODS

A multicenter study was conducted among 37 mothers and 25 fathers of 37 children on HPN (response-rate 37/49 = 76%, mean age children = 5.1 years, SD = 4.6). Parents completed three questionnaires to measure different outcomes on the KLIK website (www.hetklikt.nu): the TNO-AZL QOL Questionnaire (TAAQOL) to measure HRQOL, the Hospital Anxiety and Depression Scale (HADS) to measure anxiety and depression, and the Distress Thermometer for Parents (DT-P) to measure distress. Scores were compared to Dutch reference mothers and fathers using Mann-Whitney U-tests.

RESULTS

No differences were found in HRQOL, measured by the TAAQOL, between HPN parents compared to the reference groups, except for the subscale 'depressive emotions' for mothers (p = .01) and 'daily activities' for fathers (p = .04). HPN mothers reported higher levels of depression compared to reference mothers (p = .001). In addition, HPN mothers and fathers reported higher levels of distress than reference mothers (p = .001) and fathers (p = .03). HPN mothers reported significantly more problems in the practical, emotional, cognitive and parenting domains, fathers in the social, emotional and parenting domains.

CONCLUSIONS

On HRQOL, anxiety and depression, HPN parents generally did not show much differences compared to reference parents. However, when asked about parental distress and everyday problems, HPN treatment of their child seems highly stressful for some parents and influences daily functioning. Therefore, structural screening for parental psychosocial problems in clinical practice, e.g. using the DT-P, is necessary in order to improve the well-being of both these parents and their children dependent on HPN.

Fish oil-based lipid emulsion: current updates on a promising novel therapy for the management of parenteral nutrition-associated liver disease

Intestinal failure is characterized by loss of enteral function to absorb necessary nutrients and water to sustain life. Parenteral nutrition (PN) is a lifesaving therapeutic modality for patients with intestinal failure. Lifelong PN is also needed for patients who have short bowel syndrome due to extensive resection or a dysmotility disorder with malabsorption. However, prolonged PN is associated with short-term and long-term complications. Parenteral nutrition-associated liver disease (PNALD) is one of the long-term complications associated with the use of an intravenous lipid emulsion to prevent essential fatty acid deficiency in these patients. PNALD affects 30-60% of the adult population on long-term PN. Further, PNALD is one of the indications for isolated liver or combined liver and intestinal transplantation. There is no consensus on how to manage PNALD, but fish oil-based lipid emulsion (FOBLE) has been suggested to play an important role both in its prevention and reversal. There is significant improvement in liver function in those who received FOBLE as lipid supplement compared with those who received soy-based lipid emulsion. Studies have also demonstrated that FOBLE reverses hepatic steatosis and reduces markers of inflammation in patients on long-term PN. Future prospective studies with larger sample sizes are needed to further strengthen the positive role of FOBLE in PNALD.

Growth hormone for intestinal adaptation in patients with short bowel syndrome: systematic review and meta-analysis of randomized controlled trials

OBJECTIVES

The purpose of this systematic review was to assess the efficacy of growth hormone (GH) treatment in patients with short bowel syndrome (SBS).

METHODS

Electronic searches were performed to identify all publications describing randomized controlled trials (RCTs) on the use of GH with or without glutamine for the treatment of patients with SBS. The outcomes of interest were body weight, lean body mass, and intestinal absorption function.

RESULTS

Four trials involving 70 patients were included in the review. A meta-analysis of these trials suggested that GH had a positive effect in terms of increased weight (mean difference [MD] = 1.66; 95% CI, 0.69-2.63, P < 0.001), lean body mass (MD = 1.93; 95% CI, 0.97-2.90; P < 0.001), energy absorption (MD = 4.42; 95% CI, 0.26-8.58; P = 0.04), nitrogen absorption (MD = 4.85; 95% CI, 0.20-9.49; P = 0.04), and fat absorption (MD = 5.02; 95% CI, 0.21-9.82; P = 0.04) for patients with SBS. Adverse effects occurred during active treatment in all trials. Only 1 trial included a 12-week follow-up study.

CONCLUSIONS

The results suggest a possible short-term benefit in terms of body weight, lean body mass, and absorptive capacities; however, no conclusion of long-term efficacy of GH could be obtained. Large-scale, long-term follow-up RCTs are needed to confirm the efficacy and tolerability of GH in the future.

Significant reduction in central venous catheter-related bloodstream infections in children on HPN after starting treatment with taurolidine line lock

OBJECTIVE

The aim of this study was to review the incidence and type of central venous catheter-related bloodstream infection in children on treatment with home parenteral nutrition (PN) before and after the introduction of taurolidine. Taurolidine is a catheter lock solution that prevents biofilm formation and has broad-spectrum bactericidal and antifungal action. Its use in pediatric patients on PN has only been reported in case studies.

METHODS

A total of 19 children were reviewed, with the diagnoses of enteropathy (8 cases), short bowel syndrome (7 cases), and gastrointestinal dysmotility (4 cases). Incidence and type of sepsis were reviewed for 8 to 12 months pre- (when heparin was used) and 2 to 33 months postintroduction of the taurolidine catheter lock.

RESULTS

There were 8.6 episodes of catheter-related bloodstream infections per 1000 catheter days with heparin and 1.1 episodes per 1000 catheter days with taurolidine (P=0.002). A total of 14 of the 19 patients (74%) had no infections for up to 33 months after changing to taurolidine. No reports of multiresistant organisms or adverse effects with taurolidine were found.

CONCLUSIONS

Taurolidine line lock was associated with a decreased incidence of catheter-related bloodstream infections. This finding supports its use in patients with a history of septicemia on treatment with cyclical PN.

A qualitative study of the quality of life of children receiving intravenous nutrition at home

OBJECTIVES

To discover the views of children with severe intestinal failure treated with intravenous nutrition from early life and who remained heavily dependent on treatment throughout childhood.

METHODS

Seven children ages 7 to 17 years (mean 13 years) were interviewed. The diagnoses were enteropathy in 3, extreme short gut in 1, complex (associated mucosal inflammation and dysmotitlity) in 2, and intestinal pseudo-obstruction in 1. They were treated with intravenous nutrition overnight at home that was administered by trained parents using the simplest possible system. The children were individually questioned about their lifestyle and health. Transcripts were analysed using interpretive phenomenological analysis.

RESULTS

Children coped well with life with intravenous nutrition (apart from septicaemia in 2 cases), but were troubled when complications of the underlying disease persisted (eg, nocturnal disturbance, stool frequency, abdominal pain). Children were aware that life was restricted (eg, fewer sleepovers with friends, fewer late nights out). There was a high level of family functioning. Older children wished to take care of themselves. The burdens of life with intravenous nutrition appear to be less significant for these children than living with the effects of chronic illness. There was resilience and acceptance in the face of illness-related demands.

CONCLUSIONS

This study has found that despite the problems they may face, it is possible for children fed intravenously at home to develop a level of resilience, maintain a positive outlook, and cope well with illness-related demands even when they have had virtually lifelong severe intestinal failure. Families can continue to function well.

Pediatric short-bowel syndrome: the cost of comprehensive care

BACKGROUND

Little information is available about the financial charges incurred by patients with short-bowel syndrome (SBS). This is particularly true for pediatric SBS patients who receive some of the most complex medical care.

OBJECTIVES

The aims of this study were to determine the total cost of care for these patients and to analyze their utilization of home and hospital-based health care services.

DESIGN

This was a retrospective review of the total charges incurred by 41 children with SBS over the past decade, encompassing both inpatient and home-care charges.

RESULTS

The mean (+/- SD) total cost of care for pediatric SBS was US$505 250 +/- US$248 398 (corrected for inflation to the year 2005) for the first year of care alone. Inpatient hospitalization accounted for most of these expenses (US$416 818 +/- US$242 689, or 82% of the total), and this was attributable to prolonged requirements for intensive care resources, numerous surgical procedures, and multiple readmissions during the first year of diagnosis. Hospital-based costs steadily declined in subsequent years, but home-care services, in stark contrast, unexpectedly increased every year for the first 5 y of diagnosis-a trend that was highly significant (P < 0.005), reaching US$184 520 +/- US$111 075 for the fifth year of home care. This increasing cost was attributable to increasing complications of parenteral nutrition, especially infectious complications. Although per-patient charges varied widely, the mean total cost of care per child over a 5-y period was US$1 619 851 +/- US$1 028 985. A strong correlation was found between higher charges and infants with <10% of predicted small-bowel length.

CONCLUSIONS

This study was the first to calculate the total costs for pediatric SBS patients and to provide an in-depth analysis of these patients' actual utilization of health care services. This information may help guide health care providers and families who have children with SBS. The comprehensive care of pediatric SBS patients costs significantly more than has previously been estimated. Contrary to previous views, home care significantly increases each year after diagnosis.

The 2 STEP: an approach to repeating a serial transverse enteroplasty

PURPOSE

The serial transverse enteroplasty procedure (STEP) procedure is a successful and safe approach to lengthen small bowel in patients with short bowel syndrome (SBS). However, postlengthening dilatation may occur, which can lead to bacterial overgrowth and malabsorption. We addressed this problem by reperforming the STEP in 2 patients.

METHODS

Two infants underwent the STEP procedure at 3 days and at 4 months of life for SBS secondary to intestinal atresia and gastroschisis. The patients' small bowel lengths were 20 and 32 cm before and 25 and 52 cm after the initial STEP. Nine and 8.5 months afterward, the patients developed dilatation of the small bowel and feeding intolerance. A second STEP procedure was undertaken with additional transverse firings of staplers between previously lengthened segments and tapering of redundant blind-ending portions of bowel.

RESULTS

At operation, the bowel lengths were 45 and 62 cm. The second STEP left the patients with 61 and 73 cm of small bowel with a normalization of intestinal diameter. The first patient is doing well 5 months after surgery, and the second child tolerated increased enteral intake but died 1 year later from total parenteral nutrition-related liver failure.

CONCLUSIONS

This is the first report of a successful application of a second STEP procedure to further lengthen small bowel in SBS patients. Reapplication of the procedure requires careful stapling and a removal of small blind-ending segments to avoid further stasis.

Long-term outcome of children receiving home parenteral nutrition: a 20-year single-center experience in 302 patients

BACKGROUND

More information is needed regarding the prognosis of children receiving home parenteral nutrition (HPN). This article describes 20-year outcome data in children receiving HPN and provides separate profiles for the major pediatric diagnostic subgroups.

PATIENTS AND METHODS

This retrospective study included children who started receiving HPN between January 1, 1980, and December 31, 1999, in a single pediatric HPN center.

RESULTS

A total of 302 children were recruited, 230 (76%) with primary digestive disorders and 72 (24%) with nonprimary digestive disorders. Median age at HPN onset was 1.5 years. Median duration of HPN was 1.3 years. By January 1, 2000, 54% had weaned from HPN, 26% were still receiving HPN, 16% had died, and 4% had undergone intestinal transplantation. The survival probabilities at 2, 5, 10, and 15 years were 97%, 89%, 81%, and 72%, respectively. The likelihood and cause of death depended on the underlying diagnosis. Nine percent of children with primary digestive disorders died, 24% from their primary disease and 48% from liver disease or sepsis. Children with intractable diarrhea of infancy had the highest mortality rate (25%) and the highest incidence of liver disease (48%; P = 0.0002). Thirty-eight percent of children with primary nondigestive diseases died, 94% from their primary disease and 6% from liver disease or sepsis.

CONCLUSIONS

Outcome and survival of children receiving HPN are mainly determined by their underlying diagnosis. Nearly all children with primary digestive disease survive if referred early to an expert center.

Intestinal failure-associated liver disease: what do we know today?

Intestinal failure-associated liver disease develops in 40% to 60% of infants who require long-term total parenteral nutrition (TPN) for intestinal failure and 15% to 40% of adults on home parenteral nutrition. The clinical spectrum includes hepatic steatosis, cholestasis, cholelithiasis, and hepatic fibrosis. Progression to biliary cirrhosis and the development of portal hypertension and liver failure occurs in a minority but is more common in infants and neonates than in adults. The pathogenesis is multifactorial. In infants it is related to prematurity, low birth weight, duration of PN, short bowel syndrome requiring multiple laparotomies, and recurrent sepsis. Other important mechanisms include lack of enteral feeding, which leads to reduced gut hormone secretion; reduction of bile flow and biliary stasis, which leads to the development of cholestasis; and biliary sludge and gallstones, which exacerbate hepatic dysfunction. In adults, IFALD is less common and related to age, length of time on PN, total caloric intake, and lipid or glucose overload. In preterm infants, a deficiency of taurine or cysteine may play a role, whereas in both adults and children, choline deficiency may exacerbate IFALD. Lipid emulsions, choline deficiency, and manganese toxicity are associated with both hepatic steatosis and cholestasis in adults and children. Management strategies for the prevention of intestinal failure-induced liver disease include early enteral feeding, a multidisciplinary approach to the management of parenteral nutrition, and aseptic catheter techniques to reduce sepsis. The addition of choline, taurine, and cysteine to PN solutions may also play a role. Oral administration of ursodeoxycholic acid may improve bile flow and reduce gallbladder stasis. Survival after either isolated small bowel or combined liver and small bowel transplantation is approximately 50% at 5 years, making this an acceptable therapeutic option in adults and children with irreversible liver and intestinal failure.

Clinical Improvement Following Home Parenteral Nutrition in Pediatric Patients with Intestinal Failure

BACKGROUND/PURPOSE

Home parenteral nutrition (HPN) is being increasingly used to treat children with intestinal failure. This study evaluated the long-term growth, outcome and complications in Taiwanese pediatric patients with intestinal failure who were treated with HPN.

METHODS

This retrospective study included 27 consecutive pediatric patients with intestinal failure who received long-term HPN between 1987 and 2002. These patients were categorized into two groups according to whether they had short bowel syndrome or a bowel motility disorder. Growth, prognosis and complications, including cholestasis, hypoglycemia, hyperglycemia and infections were compared between the two groups.

RESULTS

The median age of starting HPN was significantly younger in patients with short bowel syndrome (5 months) than in patients with motility disorders (1.9 years). The median duration of HPN treatment in the overall group was 13.5 months (range, 2.1-113.1 months); weight and height increased 1.7 +/- 2.3 and 1.0 +/- 1.6 in z score, respectively. The most common complications were cholestatic liver disease (52%), hypoglycemia (15%) and hyperglycemia (33%). All patients maintained stable serum glucose levels at follow-up. Cholestatic liver disease developed after 2.3 +/- 2.0 months of total HPN in 13 patients, which subsided after 9.7 +/- 6.9 months in 11 patients, while two patients died. The mean incidence of central venous infection was 3.0 +/- 3.3 per 1000 HPN days. The most common pathogens were Staphylococcus spp. (50%) and Candida spp. (30.6%).

CONCLUSION

HPN treatment can successfully provide a bridge to enteral nutrition in pediatric patients with intestinal failure. The metabolic disturbances and cholestasis are usually transient, but infection control is important throughout the period of HPN treatment.

New and emerging therapies for short bowel syndrome in children

This review provides an overview of traditional as well as emerging therapies useful in the management of pediatric short bowel syndrome. Pediatric short bowel syndrome is relatively uncommon; however, when it does occur, it presents a unique challenge to medical care providers. The use of parenteral and enteral nutrition to maximize growth and enhance intestinal adaptation so as to increase absorptive surface area has been the primary focus of therapy. In recent years, the advent of pharmacologic advances, including the use of antibacterial drugs, anti-motility drugs and hormonal therapies, has had a significant impact on this condition. At times, surgery may be indicated for dealing with complications, or providing alternative therapy such as transplantation. With ongoing research, it is likely that improved pharmacologic therapy will be available for enhanced intestinal adaptation, control of gut motility, treatment of small bowel bacterial overgrowth, and treatment of rejection following small intestinal transplantation.

Mortality and economics in short bowel syndrome

The incidence of patients with short-bowel syndrome (SBS) has increased over the years due to progress of intensive care medicine and parenteral nutrition techniques. These techniques have significantly improved the prognosis of neonates, children and adults who have lost major parts of their intestinal tract. Long-term survival is possible and does not depend primarily on the length of the remaining bowel but on complications such as parenteral nutrition-associated cholestasis, recurrent septicaemia, central venous catheter infections, and the motility of the remaining intestine. Thus, the overall related mortality in infants with SBS ranges from 15 to 25%, and in adults from 15 to 47%, depending on the age of the patients, the underlying disease, and the duration on total parenteral nutrition. Home parenteral nutrition (HPN) significantly decreases the complication rate and improves the psychological situation of the patient. Additionally, HPN reduces in-hospital cost significantly. Nevertheless, the annual costs/patient are between $100000 and $150000. The mortality rate of SBS patients on HPN is about 30% after 5 years, which is still lower than the 5-year survival rate of intestinal grafts, and it is about equal to patients' survival after intestinal transplantation. However, the overall costs of a successful intestinal transplantation are already lower after 2 years when compared with the cost of a prolonged HPN programme.

Effects of bowel rehabilitation and combined trophic therapy on intestinal adaptation in short bowel patients

AIM: To evaluate the effects of bowel rehabilitation and combined trophic therapy on intestinal adaptation in short bowel patients.

METHODS: Thirty-eight patients with severe short-bowel syndrome (SBS) were employed in the present study, whose average length of jejunum-ileum was 35.8 ± 21.2 cm. The TPN treatment was initiated early to attain positive nitrogen balance and prevent severe weight loss. The TPN composition was designated to be individualized and altered when necessary. Enteral feeding was given as soon as possible after resection and increased gradually. Meals were distributed throughout the day. Eight patients received treatment of growth hormone (0.14 mg/kg•d) and glutamine (0.3 g/kg•d) for 3 wk. D-xylose test, ¹⁵N-Gly trace test and ¹³C-palmitic acid breath test were done to determine the patients' absorption capability.

RESULTS: Thirty-three patients maintained well body weight and serum albumin concentration. The average time of follow-up for 33 survival patients was 5.9 ± 4.3 years. Twenty-two patients weaned from TPN with an average TPN time of 9.5 ± 6.6 mo. Two patients, whose whole small bowel, ascending and transverse colon were resected received home TPN. An other 9 patients received parenteral or enteral nutritional support partly as well as oral diet. Three week rhGH + GLN therapy increased nutrients absorption but the effects were transient.

CONCLUSION: By rehabilitation therapy, most short bowel patients could wean from parenteral nutrition. Dietary manipulation is an integral part of the treatment of SBS. Treatment with growth hormone and glutamine may increase nutrients absorption but the effects are not sustained beyond the treatment period.

Psychological distress associated with home parenteral nutrition in Swedish children, adolescents, and their parents: preliminary results

OBJECTIVES

Home parenteral nutrition (HPN) is life saving in some patients with intestinal failure. Clinical experience suggests that there may be psychologic problems in HPN children, including food refusal on reintroduction of food, parent-child conflict, sibling rivalry, and disruption of family routine. The aim of this study was to investigate the psychologic distress in children with HPN and the social integration of their parents.

METHODS

The parents were asked to fill in three questionnaires anonymously--one regarding the HPN procedures; the Child Behavior Checklist, which provides a standardized description of children's behavioral problems, as reported by their mothers; and the Interview Schedule for Social Interaction (ISSI), which in its short form comprises 30 questions about social network and social support.

RESULTS

The Child Behavior Checklist questionnaires were returned from 20 families (80% response), and the ISSI questionnaires were returned from 21 families (84% response). Children and adolescents with HPN are quite distressed psychologically. The subscale within ISSI that measures social integration was significantly higher in the HPN group, whereas the subscale that measures adequacy of social integration did not differ between the groups. Both subscales measuring attachment were significantly lower in the HPN group.

CONCLUSIONS

This study shows that children and adolescents with HPN are quite distressed psychologically, even though the exact reason for this may be somewhat unclear. The social integration of the parents is high, whereas attachment, which deals with deeper, emotional relations, is negatively affected.
