CHILDREN (BASEL, SWITZERLAND) 2024; 11:536. [PMID: 38790531 PMCID: PMC11119728 DOI: 10.3390/children11050536] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/13/2024] [Revised: 04/19/2024] [Accepted: 04/27/2024] [Indexed: 05/26/2024]
Abstract
Despite limited research, existing studies using generic quality of life (QOL) tools indicate decreased physical health and compromised emotional functioning in children with IF. This study investigates QOL in children with short bowel syndrome (SBS) and its determinants. The study included 57 pediatric patients with SBS treated at Mannheim's University Hospital between 1998 and 2014. To evaluate QOL, the KINDL questionnaire was used. Three age-specific questionnaire variants were employed, and parental proxy reports were collected. Most patients underwent intestinal lengthening procedures, with varying primary diagnoses. A comparison with healthy children from the patient's perspective revealed no difference but from the parent's perspective showed lower QOL in SBS patients, especially regarding physical and mental well-being. QOL varied with age, with 7-10-year-olds reporting the lowest scores. Several factors, including independence from parenteral nutrition and the presence of a complete colon, positively influenced QOL. The independence of parenteral nutrition and the presence of a complete colon positively influenced QOL. The Bianchi technique for intestinal lengthening has also shown promise but needs further research. The observation sample in this study is too small to generalize about the whole population of SBS patients. However, this study shows that many health and treatment factors affect QOL, and a large multicenter study is necessary. Our findings underline the importance of appropriate psychological support for children with SBS and their families.

Abstract
BACKGROUND In behavioural assessment, information can be gathered from internally referenced self-reports or from proxy informants. AIMS This study aimed to fine-tune a brief but reliable method for evaluating the proxy accuracy in cases where responses obtained from adult and older adults' patient cannot be considered reliable. METHODS We generated a set of items reflecting both overt and covert behaviours related to the basic instrumental activities of daily living. The psychometric properties of the content, factorial, and criterium validity of these items were then checked. The Proxy Reliability Questionnaire-ProRe was created. We tested the frequency of "I don't know" responses as a measure of proxy reliability in a sample of healthy older adults and their proxies, and in a second sample of proxy respondents who answered questions about their parents. RESULTS As expected, response precision was lower for items characterizing covert behaviours; items about covert compared to overt behaviours generated more "I don't know" answers. Proxies provided less "I don't know" responses when evaluating the parent, they claimed they knew better. Moreover, we tried to validate our approach using response confidence. Encouragingly, these results also showed differences in the expected direction in confidence between overt and covert behaviours. CONCLUSIONS The present study encourages clinicians/researchers to how well the proxy the patient know each other, the tendency of proxies to exhibit, for example, response bias when responding to questions about patients' covert behaviours, and more importantly, the reliability of informants in providing a clinical assessment of neurocognitive diseases associated with aging.

Abstract
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.

Quality of life in long term survivors of pediatric intestinal transplantation compared with liver transplantation and home parenteral nutrition: A prospective single-center pilot study. Pediatr Transplant 2021; 25:e13982.

Abstract
Health-related quality of life (HRQOL) after intestinal transplantation (IT) is important, as many psychological troubles have been reported in these patients on the long term. Our aim was to assess and compare HRQOL of patients after IT to patients after liver transplantation (LT) or on home parenteral nutrition (HPN) for intestinal failure. A cross-sectional study included patients and their parents between 10 and 18 years of age, on HPN for more than 2 years, or who underwent IT or LT, with a graft survival longer than 2 years. Quality of life was explored by Child Health Questionnaire. Thirteen children-parents dyads after IT, 10 after LT, and eight children on HPN completed the survey. Patients were a median age of 14 years old, a median of 10 years post-transplantation or on HPN. Patients after IT scored lower than patients after LT or on HPN in "social limitations due to behavioral difficulties" and in "behavior." They scored higher than those on HPN in "global health." Parents of children after IT scored lower than those after LT in many domains. No relevant correlation with clinical data was found. Our study showed the multi-level impact of IT on quality of life of patients and their parents. It highlights the importance of a regular psychological follow-up for patients, but also of a psychological support for families. Helping the patients to overcome the difficulties at adolescence may improve their mental health in adulthood.

Abstract
A literature search determined there are no studies on children between 2 and 4 years of age who have had a liver transplant and their parents. For this reason, this study aimed to compare the quality of life of children between 2 and 4 years of age who have had a liver transplant, and the caregiving burden of their parents. The study was carried out as a descriptive cross-sectional study on 47 children who visited Inonu University Liver Transplant Institute outpatient clinic between March 2017 and March 2018. This study found that 59.6% of the children with transplants were male and 38.3% had their organ donated by their mother. There was a positive relationship between the quality of life of the parents and the quality of life and subdimensions of the children. There was a negative relationship between parental quality of life and care burden. This study found that the quality of life of children with liver transplants and their parents was low and, as the quality of life of children was impaired, the caregiving burden of parents increased. Healthcare professionals' awareness of the effect of caregivers' care load on quality of life after liver transplantation can positively affect the healing process.

Abstract
"The intestinal transplantation is reserved for patients with life-threatening complications of permanent intestinal failure or underlying gastrointestinal disease. The choice of the allograft for a particular patient depends on several factors and the presence of concurrent organ failure, and availability of the donor organs, and specialized care. Combined liver and intestinal transplant allows for patients who have parenteral nutrition-associated liver disease a possibility of improved quality of life and nutrition as well as survival. Intestinal transplantation has made giant strides over the past few decades to the present era where current graft survivals are comparable with other solid organ transplants."

Abstract
BACKGROUND/OBJECTIVES Necrotizing enterocolitis (NEC) is a serious disease linked to prematurity. A variant, NEC totalis, is associated with nearly 100% mortality. There is wide variation in counseling practices for NEC totalis. Our objectives are to determine what treatment options, if any, are offered to families, and which factors influence these decisions. METHODS An anonymous survey was distributed to members of the AAP Sections on Neonatal-Perinatal Medicine and Pediatric Surgery. Data were analyzed utilizing chi-square tests and Spearman correlations, where applicable. RESULTS In the setting of NEC totalis, 90% of the 378 respondents viewed offering life-sustaining interventions (LSI) as ethically permissible and 87% felt that transfer to another center willing to provide LSI should be considered; however, only 43% reported offering LSI to families. CONCLUSIONS Management of NEC totalis remains challenging and significant practice variability persists. Most respondents do not offer ongoing medical/surgical management, despite believing it is an ethically permissible option.

Abstract
PURPOSE This study was conducted to compare caregiving burden and social support levels of parents of children who have undergone a liver transplant. DESIGNS AND METHODS This study utilized a descriptive, cross-sectional research design. Data were collected using a parent information form, the Zarit Burden Interview, and the Multidimensional Scale of Perceived Social Support. Data were collected via face-to-face interview after written consent was obtained from the parents of children who had received a liver transplant. RESULTS Parent participants were found to have a high caregiving burden and low levels of social support from their surroundings. Parents who experienced change in their work life, social and family relationships, and had economic problems post-transplant, had a higher caregiving burden and may have lower social support. Parents whose children had a transplant from a cadaveric donor and continued to attend school were found to have a lower caregiving burden. There was a negative correlation between parent caregiving burden and social support scores; that is, caregiving burden (R2 = 0.57, p < 0.01) was significantly affected by social support (B = -0.682, β = -0.757). CONCLUSIONS This study concluded that parents receiving social support may have a lower caregiving burden, and some of their socio-demographic characteristics may have a positive effect on social support and caregiving burden. PRACTICE IMPLICATIONS Health professionals need to pay special attention to the social support and caregiving burden of parents whose children have had an organ transplant.

Abstract
BACKGROUND Small bowel transplantation (SBTX) in children receiving larger grafts from adults can be challenging because of size mismatch. The aim of the present study was to assess whether a simultaneous serial transverse enteroplasty (STEP) can address the problem of size mismatch. METHODS Three different size ratio groups between donors and recipients were compared in a porcine model with a 14-day follow-up. The groups were size matched, size mismatched (1:3.8 weight ratio), and size mismatched + STEP (each n = 8). RESULTS It was technically feasible to simultaneously perform a STEP and SBTX of a mismatched intestinal segment. The postoperative clinical course was uneventful. No signs of bleeding, leakage, stenosis, or ileus were observed and the intestinal segment was well perfused at relaparotomy. Body weight decreased in all groups, but the percentage decrease was lowest in the mismatched + STEP group. Vital enterocyte masses were similar in all the groups (citrulline levels) and the nutritional status was best in the STEP group (transferrin levels, p = 0.04). CONCLUSIONS We have demonstrated that a simultaneous STEP and SBTX procedure is technically feasible and clinically useful in overcoming the challenges associated with size mismatched SBTX. Our short-term findings justify further investigation in a larger series to elucidate the long-term outcomes of this procedure.

Abstract
Pediatric patients with irreversible intestinal failure present a significant challenge to meet the nutritional needs that promote growth. From 2002 to 2013, 13 living-related small intestinal transplantations were performed in 10 children, with a median age of 18 months. Grafts included isolated living-related intestinal transplantation (n=7), and living-related liver and small intestine (n=6). The immunosuppression protocol consisted of induction with thymoglobulin and maintenance therapy with tacrolimus and steroids. Seven of 10 children are currently alive with a functioning graft and good quality of life. Six of the seven children who are alive have a follow-up longer than 10 years. The average time to initiation of oral diet was 32 days (range, 13-202 days). The median day for ileostomy takedown was 77 (range, 18-224 days). Seven children are on an oral diet, and one of them is on supplements at night through a g-tube. We observed an improvement in growth during the first 3 years post-transplant and progressive weight gain throughout the first year post-transplantation. Growth catch-up and weight gain plateaued after these time periods. We concluded that living donor intestinal transplantation potentially offers a feasible, alternative strategy for long-term treatment of irreversible intestinal failure in children.

Abstract
Background One-year survival rates for intestine transplant recipients have increased to 70%, but it is believed that the complications following the procedure do not diminish after the first year as is seen in other forms of solid-organ transplantation. Objective To review the ongoing medical requirements of an increasing number of long-term survivors of intestinal transplantation. Method A retrospective medical chart review was completed on all patients who received intestinal transplantation at the University of Nebraska Medical Center from September 1990 through March 2003. One hundred forty-six transplantations were performed on 128 patients—53 intestinal, 70 liver/intestinal, and 23 intestinal with liver and pancreas or kidney. Results Seventy-six patients survived longer than 365 days and form the study group. Major reasons for readmissions were infections, gastrointestinal complications, dehydration, and rejection. The average number of rehospitalizations per patient per year remained constant. Death in patients with more than 365 days survival (N=23) was the result of sepsis (56%) and multiple other complications (44%). Conclusion The number of readmissions each year per patient remains constant and medical problems remain complex and life threatening. Patients with intestinal transplantation will continue to require regular expert follow-up care and careful attention to even the smallest medical problem even years following transplantation.

Abstract
As technology introduces more advanced therapies, individuals have realized that quantity or length of life may not always be the ultimate goal in treating disease. The quality of life at times is as important as length of life. In this article, we review the literature regarding quality of life after intestinal transplantation. Published data on patient survival are briefly reviewed and the available studies investigating quality of life are examined. Few studies have been performed to date, but the limitations and implications of the available studies are summarized.

Abstract
Intestinal transplantation has now emerged as a lifesaving therapeutic option and standard of care for patients with irreversible intestinal failure. Improvement in survival over the years has justified expansion of the indications for intestinal transplantation beyond the original indications approved by Center for Medicare and Medicaid services. Management of patients with intestinal failure is complex and requires a multidisciplinary approach to accurately select candidates who would benefit from rehabilitation versus transplantation. Significant strides have been made in patient and graft survival with several advancements in the perioperative management through timely referral, improved patient selection, refinement in the surgical techniques and better understanding of the immunopathology of intestinal transplantation. The therapeutic efficacy of the procedure is well evident from continuous improvements in functional status, quality of life and cost-effectiveness of the procedure. This current review summarizes various aspects including current practices and evidence based recommendations of intestinal transplantation.

The impact of pediatric organ transplantation on parents' quality of life and family functioning has been found to be substantial, but findings on this topic have not previously been consolidated. Thirty-one studies were selected for analysis after a database search on this topic. We present future research questions and suggestions to improve clinical practice based on the integration of this knowledge.

Abstract
The Registry has gathered information on intestine transplantation (IT) since 1985. During this time, individual centers have reported progress but small case volumes potentially limit the generalizability of this information. The present study was undertaken to examine recent global IT activity. Activity was assessed with descriptive statistics, Kaplan-Meier survival curves and a multiple variable analysis. Eighty-two programs reported 2887 transplants in 2699 patients. Regional practices and outcomes are now similar worldwide. Current actuarial patient survival rates are 76%, 56% and 43% at 1, 5 and 10 years, respectively. Rates of graft loss beyond 1 year have not improved. Grafts that included a colon segment had better function. Waiting at home for IT, the use of induction immune-suppression therapy, inclusion of a liver component and maintenance therapy with rapamycin were associated with better graft survival. Outcomes of IT have modestly improved over the past decade. Case volumes have recently declined. Identifying the root reasons for late graft loss is difficult due to the low case volumes at most centers. The high participation rate in the Registry provides unique opportunities to study these issues.

Abstract
To determine HRQOL after pediatric intestinal transplantation. Thirty-four IT survivors from 1999 to 2012 were asked to complete age-specific HRQOL non-disease-specific questionnaires: TAPQOL (0-4 yr), KINDL-R (5-7 yr; 8-12 yr; 13-17 yr), and SF-36v2 (>18 yr), all validated with Spanish population. Primary caregiver completed a SF-36 questionnaire and CBI. Thirty-one participants were included. Median age was 10.2 yr (1-29) and time after transplant 4.4 yr (0-13). Overall patient scores were 78.2 ± 10.6 (n = 8), 83.3 ± 9.7 (n = 6), 72.2 ± 9.21 (n = 6), 80.5 ± 12.4 (n = 7), and 82.2 ± 12.4 (n = 4) for each age group. Highest scores were obtained for vitality (group I), self-esteem (group IV), and physical and social functioning and emotions (group V). Lowest scores were obtained in appetite and behavior (I), family and school (III), and chronic disease perception (III, IV). No significant differences were found between caregivers and their children. CBI showed stress in 52%. SF-36 for caregivers was lower than general population. No significant differences were found depending on relevant clinical and sociodemographic data. HRQOL was acceptable and improved with age and time since transplantation. Parents had a slighter own QOL and worse perception of health than their children. When successful, intestinal transplantation allows a normal life in most patients and can be offered as an attractive option.

Abstract
As survival rates for pediatric solid organ transplantation have continued to improve, researchers and healthcare providers have increasingly focused on understanding and enhancing the HRQOL and psychosocial functioning of their patients. This manuscript reviews the psychosocial functioning of pediatric transplant recipients during the "later years," defined as more than three yr post-transplant, and focuses on the day-to-day impact of living with a transplant after the immediate period of adjustment and early years after surgery. Key topics reviewed include HRQOL, cognitive functioning, impact on the family, regimen adherence, and transition of responsibility for self-management tasks. Overall, pediatric transplant recipients evidence impairment in HRQOL, neuropsychological outcomes, and family functioning as compared to non-transplant recipients. However, the degree of impairment is influenced by a variety of factors including, disease severity, age, solid organ type, and study methodologies. Studies are limited by small samples, cross-sectional design, and the lack of universal assessment battery to allow for comparisons across solid organ populations. Areas for future research are discussed.

Abstract
Objective Quality of life (QoL) has become a mainstay in the outcome assessment of pediatric solid-organ transplant recipients. Yet, how QoL is operationalized and measured varies drastically. It may be very difficult for clinicians and researchers to determine which methods of QoL assessment best meet the needs of their patients or study. The purpose of this literature review is to describe and evaluate the current status of QoL measurement in studies of pediatric solid-organ transplant recipients. Data Sources Searches of PubMed and PsycINFO from January 1985 to February 2012. Study Selection English peer-reviewed publications that described a method for measuring QoL whether it was a standardized questionnaire, qualitative approach, or another way of operationalizing the construct. Data Extraction QoL measurement strategies were extracted from 43 studies that met inclusion criteria. Data Synthesis Each article was reviewed and summarized by 2 study team members. Conclusions Many different strategies were used for measurement, and some were not consistent with established conceptualizations of QoL. Overall recommendations for best practices are offered. Detailed information about specific measures is included, and measures that seem to capture the construct well are recommended. Additionally, our review highlighted the importance of using a “battery approach,” including child and parent report as well as considering other variables, such as patient's age, when selecting a QoL measurement strategy.

Abstract
Solid organ transplantation has transformed the lives of many children and adults by providing treatment for patients with organ failure who would have otherwise succumbed to their disease. The first successful transplant in 1954 was a kidney transplant between identical twins, which circumvented the problem of rejection from MHC incompatibility. Further progress in solid organ transplantation was enabled by the discovery of immunosuppressive agents such as corticosteroids and azathioprine in the 1950s and ciclosporin in 1970. Today, solid organ transplantation is a conventional treatment with improved patient and allograft survival rates. However, the challenge that lies ahead is to extend allograft survival time while simultaneously reducing the side effects of immunosuppression. This is particularly important for children who have irreversible organ failure and may require multiple transplants. Pediatric transplant teams also need to improve patient quality of life at a time of physical, emotional and psychosocial development. This review will elaborate on the long-term outcomes of children after kidney, liver, heart, lung and intestinal transplantation. As mortality rates after transplantation have declined, there has emerged an increased focus on reducing longer-term morbidity with improved outcomes in optimizing cardiovascular risk, renal impairment, growth and quality of life. Data were obtained from a review of the literature and particularly from national registries and databases such as the North American Pediatric Renal Trials and Collaborative Studies for the kidney, SPLIT for liver, International Society for Heart and Lung Transplantation and UNOS for intestinal transplantation.

Abstract
Intestinal failure (IF) occurs when a person's functional intestinal mass is insufficient. Patients with IF are placed on parenteral nutrition (PN) while efforts are made to restore intestinal function through surgical or medical intervention. Patients who fail standard IF therapies may be candidates for intestinal transplantation (IT). Clinical outcomes for IT have improved to make this therapy the standard of care for patients who develop complications of PN. The timing of referral for IT is critical because accumulated complications of PN can render the patient ineligible for IT or can force the patient to await multiorgan transplantation.

Abstract
As outcomes after ITx improve, greater emphasis is needed on HRQOL. The primary aims of this study were to (i) assess the feasibility of measuring HRQOL in pediatric ITx recipients, (ii) measure HRQOL using validated instruments, and (iii) compare HRQOL in ITx recipients to healthy normal (NL) children. The CHQ and Pediatric Quality of Life (PedsQL4.0) instruments were administered to both patients and parents at outpatient visits. All 24 eligible patients were enrolled. The median age at study enrollment was 6.0 yr (range: 2-18 yr), and the median time from transplant to study enrollment was 2.8 yr (range: 0.5-11.8 yr). The majority of subjects were male (58%), Latino (58%), and liver-inclusive (92%) recipients. For CHQ and PedsQL4.0, parental responses were significantly lower in multiple categories including physical health and social functioning compared to healthy norms. Patient responses were not different from NL using CHQ but using PedsQL4.0 were significantly lower in the school functioning subcategory and psychosocial health summary score. HRQOL as reported by children and families after ITx is significantly lower in multiple categories compared to NL.

Abstract
LaR Pediatric solid-organ transplantation is an increasingly successful treatment for organ failure. Five- and 10-yr patient survival rates have dramatically improved over the last couple of decades, and currently, over 80% of pediatric patients survive into adolescence and young adulthood. Waiting list mortality has been a concern for liver, heart, and intestinal transplantation, illustrating the importance of transplant as a life-saving therapy. Unfortunately, the success of pediatric transplantation comes at the cost of long-term or late complications that arise as a result of allograft rejection or injury, immunosuppression-related morbidity, or both. As transplant recipients enter adolescence treatment, non-adherence becomes a significant issue, and the medical and psychosocial impacts transition to adulthood not only with regard to healthcare but also in terms of functional outcomes, economic potential, and overall QoL. This review addresses the clinical and psychosocial challenges encountered by pediatric transplant recipients in the current era. A better understanding of pediatric transplant outcomes and adult morbidity and mortality requires further ongoing assessment.

Abstract
INTRODUCTION Intestinal transplantation has become an accepted therapy for individuals permanently dependent on total parenteral nutrition (TPN) with life-threatening complications. Quality of life and psychological well-being can be seen as important outcome measures of transplantation surgery. METHODS We evaluated 24 adult intestinal transplant recipients and 24 healthy subjects (a control group). All subjects were administered the Italian Version of the Psychological Well-Being Scales (PWB) by C. Ryff, the World Health Organization Quality of Life-Brief (WHOQOL), and the Symptom Questionnaire (SQ) by R. Kellner and G.A. Fava, a symptomatology scale. Quality of life and psychological well-being were assessed in transplant recipients in relationship to the number of rejections, the number of admissions, and the immunosuppressive protocol. RESULTS Intestinal transplant recipients reported significantly higher scores in the "personal growth" category (P = .036) and lower scores in the "positive relation with others" (P = .013) and "autonomy" (P = .007) dimensions of PWB, compared with the controls. In the WHOQOL, the scores of transplant recipients were lower only in the psychological domain (P = .011). Transplant recipients reported significantly higher scores in the "somatic symptom" (P = .027) and "hostility" (P = .018) dimensions of the SQ, compared with the controls. Transplant recipients with number of admissions >8 reported higher scores in "anxiety" (P = .019) and "depression" (P = .021) scales of the SQ, and the patients with a Daclizumab protocol reported higher scores in "depression" (P = .000) and "somatic symptom" (P = .008) of the SQ. There were no significant differences regarding number of rejections and socio-demographic variables. CONCLUSION Improvement of psychological well-being in the transplant population may be related to the achievement of the goal of transplantation: recovery of bowel function. But the data confirmed that the transplant experience required a long and difficult adaptation trial to the new condition of "transplant recipient."

Abstract
BACKGROUND Infants with parenteral nutrition dependence may develop liver dysfunction and progress to liver failure requiring transplantation. The aspartate aminotransferase-to-platelet ratio index (APRI) has good correlation with liver fibrosis progression in adults. This study applies APRI scoring to parenteral nutrition-dependant, short-gut infants to determine hepatic fibrosis progression. METHODS Laboratory values and biopsies were collected from initial intestinal resection (time 0) up to transplantation (end). Fibrosis scoring ranged from F0 (normal) to F4 (cirrhosis). Children were divided into 3 groups: (1) isolated intestine; and combined liver/intestine with gestational age (2) 34 weeks or greater and (3) 30 weeks or less. Liver function values over time, including calculated APRI, were analyzed as predictors of fibrosis. RESULTS Fifteen children who had 33 biopsies were included. Median APRI by fibrosis grade was F < or = 2: 1.88, F3: 3.23, and F4: 14.16 (P < .01). Median APRI at transplant by study group was (1) isolated intestine: 2.47, (2) liver/intestine 35 weeks or longer EGA: 14.16, and (3) liver/intestine 30 weeks or less EGA: 14.74 (P = .04). CONCLUSION Progression of APRI up to 60 days initially demonstrates similar values among study groups, but over time the score distinguishes those children with impending liver cirrhosis and differentiates fibrosis grade and study group.

Abstract
Long-term survival after pediatric solid organ transplantation is now the rule rather than the exception for increasing numbers of children with end-stage organ diseases. While transplantation restores organ function it does not necessarily return one to a normal life. Therefore, it is prudent to focus on assessment of not only traditional biologic outcomes but also the quality life for these children and their families. This article gives a brief overview of current definitions, conceptualizations, approaches to measurement of, and unique considerations in the evaluation of quality of life in children who have undergone solid organ transplant. Current understanding of quality of life in children who have undergone solid organ transplantation is reviewed, followed by limitations of current knowledge. Clinical implications are discussed and future research directions suggested.

Abstract
This article reviews the current status of pediatric intestinal transplantation, focusing on referral and listing criteria, surgical techniques, patient management, monitoring, complications after transplant, and short- and long-term patient outcome. Intestine transplantation has become the standard of care for children who develop life-threatening complications associated with intestinal failure. The results of intestinal failure treatment have significantly improved in the last decade following the establishment of gut rehabilitation programs and advances in transplant immunosuppressive protocols, surgical techniques, and posttransplant monitoring. The 1-year patient survival is now 80% and more than 80% of the children who survive the transplant are weaned off parenteral nutrition. Early referral for pretransplant assessment and careful follow-up after transplant with prompt recognition and treatment of transplant-related complications are key factors contributing to superior patient outcomes and survival. The best results are being obtained at high-volume centers with survival rates of up to 75% at 5 years.

Abstract
PURPOSE OF REVIEW This review highlights current outcomes in intestinal transplantation and summarizes advances that have recently occurred in five interrelated areas: progress in intestinal rehabilitation, immunologic and technical modifications, awareness of opportunities for improved allograft monitoring, and better assessment of long-term complications and morbidities. RECENT FINDINGS Improved long-term management of patients with intestinal failure as well as improved outcomes with intestine transplant are changing the previously established paradigms of timing for referral. For those requiring transplant, use of monoclonal and polyclonal antibody induction protocols have been associated with improved outcomes. Experience at centers of excellence demonstrates 1 and 5 year patient survival rates of 93 and 78%, respectively with ongoing investigations focusing on lowering long-term causes of graft loss such as chronic rejection or morbidities such as renal dysfunction. Descriptions of tissue, proteomic and genomic technologies to complement traditional methodologies to monitor graft function are emerging. SUMMARY Optimal timing for referral of children with intestinal failure and improved medical and surgical therapies increase the opportunity for intestinal adaptation without the need for transplant. For those undergoing transplant, technical and immunologic modifications, developments in graft monitoring, and reduction of long-term morbidities are leading to improved outcomes.

Abstract
Irreversible intestinal failure in children is predominantly caused by surgical conditions such as volvulus, necrotizing enterocolitis, and gastroschisis. Functional intestinal failure from motility disorders such as intestinal pseudo-obstruction or enterocyte dysfunction with microvillus inclusion disease also may require intestine replacement. Approved indications for intestinal transplantation include liver dysfunction, loss of major venous access, frequent central line-related sepsis, and recurrent episodes of severe dehydration despite intravenous fluid management. Surgical options include transplantation of the isolated intestine, combined liver-intestine transplantation, or multivisceral transplantation of the stomach, duodenum, pancreas, and small bowel (with or without the liver). Immunosuppression for intestinal transplantation is based on tacrolimus therapy, often with induction immunosuppression using antilymphocyte antibodies (eg, antithymocyte antibody and alemtuzumab). Experience at centers of excellence demonstrates 1- and 5-year patient survival rates of 95% and 77%, respectively, with ongoing investigations focusing on lowering long-term causes of graft loss such as chronic rejection.

Abstract
Pediatric small bowel transplant recipients are susceptible to diarrhea due to rejection or infectious enteritis, particularly of viral etiology. The most common causes of viral enteritis in this setting are rotavirus, adenovirus, cytomegalovirus, and Epstein-Barr virus. This study is the first to compare the histologic findings of rotavirus infection with acute cellular rejection in small bowel transplant biopsies. Three patients with small bowel transplants had rapid stool antigen test-proven rotavirus infection. Endoscopic biopsies during infection were examined, including material from the allograft, native small bowel, stomach, and colon. Biopsies from 2 of the patients during unrelated episodes of mild acute cellular rejection were also evaluated. Blunting of villi was the most common finding in rotavirus infection. Additionally, there was a mononuclear infiltrate that was "top heavy," or denser towards the lumen. There were surface apoptoses but no increase in crypt apoptotic figures. In contrast, during mild acute cellular rejection, there was no villous blunting, the mononuclear infiltrate was diffuse, and there were increased crypt apoptosis. As expected, the changes of acute cellular rejection were confined to the graft, in contrast to rotavirus infection, in which case native bowel often had more pronounced changes. Although the small number of patients limits this study, several histologic features were helpful in identifying rotavirus infection. These were blunting of villi, distribution of the inflammatory infiltrate, number and location of apoptotic bodies, and anatomic location of the effect. A larger follow-up study would be valuable to confirm these findings.

Abstract
This study aims to understand families' dynamics during the experience of pediatric liver transplantation, and to identify families' demands and resources. Symbolic interactionism was used as the theoretical framework and grounded theory as the methodological reference. Data were collected through semi-structured interviews with eight families at a public hospital in Sao Paulo, SP, Brazil. Two phenomena were identified: having life controlled by the transplantation represents the vulnerability of families experiencing uncertainty and fear during their children's disease experience; and struggling to reacquire autonomy refers to families' reaction when exposed to the first phenomenon, which consists of continuous adaptation to overcome suffering caused by the situation. The relationship of these two phenomena allowed for the identification of the central category: not being able to live like before. Based on this analysis, a theoretical model could be proposed to explain the experience.

Abstract
AIM To systematically review the literature published since 1999 on paediatric health-related quality of life (HRQL) in relation to parent-child agreement. METHODS Literature searches used to identify studies which evaluated parent-child agreement for child HRQL measures. RESULTS Nineteen studies were identified, including four HRQL instruments. The Pediatric Quality of Life Inventory (PedsQL) was most commonly used. Differences in parent-child agreement were noted between domains for different measures. The impact of child and parent characteristics were not consistently considered; however parents of children in a nonclinical sample tended to report higher child HRQL scores than children themselves, while parents of children with health conditions tended to underestimate child HRQL. CONCLUSION Despite increasing numbers of studies considering children's HRQL, information about variables contributing to parent-child agreement levels remains limited. Authors need to consistently provide evidence for reliability and validity of measures, and design studies to systematically investigate variables that impact on levels of parent-child agreement.

Abstract
Developments in solid organ transplantation have resulted in improved survival for children with advanced kidney, liver, and heart disease; however, concerns have been raised regarding the quality of life of survivors. This study examined HRQOL in adolescent transplant recipients. We examined the influence of demographic, treatment regimen, and family factors on physical and mental health domains of HRQOL. The current single-center investigation involved 68 solid organ transplant recipients and their parents. All families participated in a structured interview to collect information on demographics, characteristics of the adolescents' disease and treatment regimen, family functioning, and HRQOL for parents and adolescents. Using hierarchical regression analyses, predictive models of physical functioning and mental health outcomes for adolescent transplant recipients were developed for parent-proxy and adolescent self-report. Perceived frequency of medication side-effects and family conflict significantly contributed to adolescent physical functioning and mental health outcomes. Taken together, transplant consequences and family environment significantly impact physical and mental health outcomes in adolescent transplant recipients. Our findings demonstrate the need for pharmacological considerations and psychological interventions to address these areas.

Abstract
The clinical introduction of intestinal transplantation has added a new dimension and offered a valid therapeutic option for patients with irreversible intestinal failure. In the year 2000, the Center for Medicare & Medicaid Services (CMS) recognized intestinal, combined liver-intestinal, and multivisceral transplantation as the standard of care for patients with irreversible intestinal and parenteral nutrition (PN) failure. Accordingly, the indications for the procedure are currently limited to those who develop life-threatening PN complications. However, a recent improvement in survival similar to other solid organ transplant recipients should justify lifting the current restricted criteria, and the procedure should be considered before the development of PN failure. Equally important is the awareness of the recent evolution in nutrition management and outcome after transplantation. Early and progressive enteral feeding using a complex polymeric formula is safe and effective after successful transplantation. Full nutrition autonomy is universally achievable among most intestinal and multivisceral recipients, with enjoyment of unrestricted oral diet. Such a therapeutic benefit is commonly maintained among long-term survivors, with full rehabilitation and restoration of quality of life.

Abstract
OBJECTIVES The differences between child self-reports and parent proxy reports of quality of life in a large population of children with cerebral palsy were studied. We examined whether child characteristics, severity of impairment, socioeconomic factors, and parental stress were associated with parent proxy reports being respectively higher or lower than child self-reports of quality of life. METHODS This study was conducted in 2004-2005 and assessed child quality of life (using the Kidscreen questionnaire, 10 domains, each scored 0-100) through self-reports and parent proxy reports of 500 children aged 8 to 12 years who had cerebral palsy and were living in 7 countries in Europe. RESULTS The mean child-reported scores of quality of life were significantly higher than the parent proxy reports in 8 domains, significantly lower for the finances domain, and similar for the emotions domain. The average frequency of disagreement (child-parent difference greater than half an SD of child scores) over all domains was 64%, with parents rating their child's quality of life lower than the children themselves in 29% to 57% of child-parent pairs. We found that high levels of stress in parenting negatively influenced parents' perception of their child's quality of life, whereas the main factor explaining parents' ratings of children's quality of life higher than the children themselves is self-reported severe child pain. CONCLUSIONS This study shows that the factors associated with disagreement are different according to the direction of disagreement. In particular, parental well-being and child pain should be taken into account in the interpretation of parent proxy reports, especially when no child self-report of quality of life is available. In the latter cases, it may be advisable to obtain additional proxy reports (from caregivers, teachers, or clinicians) to obtain complementary information on the child's quality of life.

Abstract
Over the past 15 years, intestinal transplantation for the treatment of intestinal failure has changed from a desperate last-ditch effort into a standard therapy for which a good outcome is expected. Patient survival after intestinal transplantation has improved in the past 3-5 years and now approaches that of other solid organ allograft recipients, including liver and kidney, and is similar to survival on permanent therapy with parenteral nutrition. Complications are more common and often more severe during the initial hospitalization period after intestinal transplantation than they are after transplantation of other solid organs. After intestinal transplantation the initial hospitalization period is, therefore, usually 3-8 weeks long. Nearly all patients discharged after intestinal transplantation have good allograft function and have been weaned from total parenteral nutrition. The cost of the initial hospitalization period is one to two times the cost of permanent total parenteral nutrition for 1 year, which means that, in most cases, intestinal transplantation is cost-saving within 2 years of transplantation. In addition, quality of life after intestinal transplantation, as determined by standardized quality of life measures, is good or normal.

Abstract
The goal of organ transplantation is not only to ensure the survival of individuals with end-stage heart, lung, liver, kidney, pancreas, and small bowel diseases, but also to offer patients the health they enjoyed before the disease, achieving a good balance between the functional efficacy of the graft and the patient's psychological and physical integrity. Quality of life (QoL) assessments are used to evaluate the physical, psychological, and social domains of health, seen as distinct areas that are influenced by a person's experiences, beliefs, expectations, and perceptions, and QoL is emerging as a new medical indicator in transplantation medicine too.

Abstract
Organ transplantation is a procedure that can save and prolong the life of individuals with end-stage heart, lung, liver, kidney, pancreas and small bowel diseases. The goal of transplantation is not only to ensure their survival, but also to offer patients the sort of health they enjoyed before the disease, achieving a good balance between the functional efficacy of the graft and the patient's psychological and physical integrity. Quality of life (QoL) assessments are used to evaluate the physical, psychological and social domains of health, seen as distinct areas that are influenced by a person's experiences, beliefs, expectations and perceptions, and QoL is emerging as a new medical indicator in transplantation medicine too. This review considers changes in overall QoL after organ transplantation, paying special attention to living donor transplantation, pediatric transplantation and particular aspects of QoL after surgery, e.g. sexual function, pregnancy, schooling, sport and work.

Abstract
Even though surgical techniques for isolated intestine, liver-intestine, and multivisceral transplantations were developed in the 1960's, very few patients were transplanted before 1990 because initial immunosuppression regimens were insufficient, making intestine transplantation impossible. Intestine transplantation resulted in death in most patients within days or months. The discouraging results of the first clinical trials were due to technical complications, sepsis, and the failure of conventional immunosuppression to control rejection. By 1990 the development of tacrolimus-based immunosuppression and improved surgical techniques, the increased array of potent immunosuppressive medications, infection prophylaxis, and suitable patient selection helped improve actuarial graft and patient survival rates for all types of intestine transplantation. The aims of this review are to describe the current status of intestine transplantation including the underlying diseases and conditions that may be indications for intestine transplantation, to identify patient populations for this indication, to provide key steps for patient evaluation, to summarize current recommendations for immunosuppression, to list the most common postoperative complications, and to discuss the international experience of small bowel transplantation compiled and analyzed by the International Intestine Transplant Registry since 1985.

Abstract
BACKGROUND The outcome from small bowel transplantation (SBTx) has improved progressively over the past decade raising questions as to whether indications should be broadened from those currently followed based on "TPN (total parenteral nutrition) failure." OBJECTIVE AND METHODS To assess current outcome, we studied the effect of transplantation on nutritional autonomy, organ function, and quality of life (QoL) measured by a validated self-administered questionnaire containing 26 domains and 130 questions, for a minimum of 12 months in a cohort of 46 consecutively transplanted patients between June 2003 and July 2004. The majority of transplanted patients (76%) had intestinal failure because of extreme short bowel, the remainder having either chronic pseudo-obstruction or porto-mesenteric vein thrombosis (PMVT). All but the PMVT patients were dependent on home TPN (HPN) (median 2, range 0-25 yr) and had developed serious recurrent infective complications with (25%) or without central vein thrombosis and liver failure. Sixty-one percent received a liver in addition to a small intestine. RESULTS Follow-up was for a mean of 21 (range 12-36) months. Five patients died, two with chronic graft rejection. All the remaining patients have graft survival with an average of 1.2 (range 0-5) episodes of acute rejection. All patients were weaned from TPN by a median of 18 days (range 1-117 days) and from tube feeding by day 69 (range 22-272 days). There was a significant improvement in overall assessment of QoL and in 13 of 26 of the specific domains examined. CONCLUSION Our results confirm the claim that a new era has dawned for SBTx, such that, with continued progress, it can potentially become an alternative to HPN for the management of permanent intestinal failure, rather than a last-chance treatment for "TPN failure."

Abstract
INTRODUCTION Intestinal transplantation has become a life-saving therapy in patients with irreversible loss of intestinal function and complications of total parenteral nutrition. DISCUSSION The patient and graft survival rates have improved over the last years, especially after the introduction of tacrolimus and rapamycin. However, intestinal transplantation is more challenging than other types of solid organ transplantation due to its large amount of immune competent cells and its colonization with microorganisms. Moreover, intestinal transplantation is still a low volume procedure with a small number of transplanted patients especially in Germany. A current matter of concern is the late referral of intestinal transplant candidates. CONCLUSION Thus, patients often present after onset of life-threatening complications or advanced cholestatic liver disease. Earlier timing of referral for candidacy might result in further improvement of this technique in the near future.
