Abstract
BACKGROUND Recombinant human growth hormone (rhGH) is widely used to treat growth retardation in children. We aimed to examine the effect of rhGH therapy on growth and its impact on allograft function in children with growth retardation after intestinal transplant (IT). METHODS We retrospectively included children younger than 19 years who had received an IT with or without the liver, were diagnosed with growth retardation, and have received rhGH between January 2010 and January 2021. Changes in the patient's anthropometric parameters between baseline and various time points were compared using the paired t-test or Wilcoxon signed-rank test, as appropriate. RESULTS Seven patients (all males and prepubertal) received rhGH for the median duration of 2.3 years. The median age at rhGH start was 9.5 years. The median growth velocity z-score improved from -0.95 before treatment to 2.3 (p = .04) and 1.9 (p = .06) after 1 and 2 years of treatment, respectively. The median height-for-age z-score significantly improved from -3.4 at rhGH start to -1.3 (p = .005) at rhGH stop and remained above baseline at the last visit (-2.4, p = .002). The change in the first-year growth velocity was negatively correlated with the change in the second-year growth velocity (r = -.90, p = .04). No serious adverse effects or worsening allograft function were observed. CONCLUSIONS Severely growth retarded children after IT could benefit from rhGH treatment. A larger, longitudinal study would be warranted to monitor the long-term effect and safety of rhGH and examine predictors of growth response to rhGH therapy in these pediatric IT recipients.

Abstract
Despite recent advances, the causes of and effective therapies for pediatric chronic cholestatic diseases remain elusive, and many patients progress to liver failure and need liver transplantation. Malnutrition is a common complication in these patients and is a well-recognized, tremendous challenge for the clinician. We undertook a narrative review of both recent and relevant older literature, published during the last 20 years, for studies linking nutrition to pediatric chronic cholestasis. The collected data confirm that malnutrition and failure to thrive are associated with increased risks of morbidity and mortality, and they also affect the outcomes of liver transplantation, including long-term survival. Malnutrition in children with chronic liver disease is multifactorial and with multiple potential nutritional deficiencies. To improve life expectancy and the quality of life, patients require careful assessments and appropriate management of their nutritional statuses by multidisciplinary teams, which can identify and/or prevent specific deficiencies and initiate appropriate interventions. Solutions available for the clinical management of these children in general, as well as those directed to specific etiologies, are summarized. We particularly focus on fat-soluble vitamin deficiency and malnutrition due to fat malabsorption. Supplemental feeding, including medium-chain triglycerides, essential fatty acids, branched-chain amino acids, and the extra calories needed to overcome the consequences of anorexia and high energy requirements, is reviewed. Future studies should address the need for further improving commercially available and nutritionally complete infant milk formulae for the dietary management of this fragile category of patients. The aid of a specialist dietitian, educational training regarding nutritional guidelines for stakeholders, and improving family nutritional health literacy appear essential.

Resting Energy Expenditure of Children With End-stage Chronic Liver Disease Before and After Liver Transplantation. J Pediatr Gastroenterol Nutr 2019; 69:102-107. [PMID: 30908388 DOI: 10.1097/mpg.0000000000002344] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 12/12/2022]
Abstract
OBJECTIVES Our objective was to test the hypothesis that children with end-stage chronic liver disease (ESCLD) are hypermetabolic when compared to healthy children, and that this hypermetabolism persists for at least 6 months after liver transplant. METHODS Seventeen patients with end-stage chronic liver disease and 14 healthy controls had their resting energy expenditure measured (mREE) by indirect calorimetry. Weight, height, and body mass index were converted to standard deviation (SD) scores. Children older than 5 years had air displacement plethysmography and patients older than 5 years also had whole body dual-energy X-ray absorptiometry with characterization of fat mass (FM), fat-free mass (FFM), and bone-free fat free (lean) mass. RESULTS When compared to the prediction equation 44% of the patients and 50% of the healthy controls were hypermetabolic. The younger patients (0-5 years) had a lower mREE than the healthy controls but were significantly lighter and shorter than their healthy counterparts. mREE correlated strongly for all children with age, weight, height, and FFM. There was a strong negative correlation between age and mREE/kg in both patients (rs = -0.94, P < 0.01) and controls (rs = -0.91, P < 0.01). Almost 84% of the variance in mREE was explained by age (P < 0.001). There were no significant differences between resting energy expenditure (REE)/FFM between the 2 groups. mREE/kg before liver transplant correlated with mREE/kg after transplant (Pearson r = 0.83, P < 0.01). CONCLUSIONS REE mostly reflected the size of the child. The patients were not hypermetabolic when compared to the healthy children. The main determinant of REE/kg after transplant was REE/kg before transplant.

Abstract
OBJECTIVE The aim of the study is to identify early predictors of long-term overweight and obesity in pediatric liver transplant recipients. METHODS Single-center, retrospective review of children who underwent liver transplant before age 6 years. Body mass index (BMI), weight, and height percentiles at transplant and post-transplant were calculated. BMI, weight gain trajectories, and failure-to-thrive (FTT) were examined as predictors of overweight/obesity at 3 and 5 years post-transplant. RESULTS Children (n = 70) were median 0.9 years at transplant. Median BMI percentile increased from 37 (interquartile range (IQR) 12-73) at transplant to 83 (IQR 64-97) at 12 months, with median weight percentile 47 (IQR 26-67) and height percentile 9 (IQR 2-32). Overweight/obesity prevalence peaked at 3 years post-transplant (44%). Children who were overweight/obese at 3 years post-transplant were more likely to be overweight/obese at transplant, and at 6 and 12 months post-transplant (odds ratio (OR): 9.4, P = 0.02; OR: 6.7, P = 0.013, OR: 6.4, P = 0.007, respectively). The prevalence of overweight/obesity decreased to 26% at 5 years. Rapid weight gain post-transplant did not predict overweight/obesity at 3 or 5 years. Over one-third of children who were FTT at transplant were overweight/obese at 3 or 5 years, but FTT at transplant did not increase later obesity risk. CONCLUSIONS Most children gain weight rapidly after liver transplant. Nearly half of transplant recipients are overweight/obese at 3 years, but the prevalence decreases by 5 years. Those who become overweight/obese tend to do so within 1 year post-transplant, making this an important time to identify high-risk children and provide counseling.

Abstract
Patients transplanted for cholestatic liver disease are often significantly fat-soluble vitamin deficient and malnourished pretransplant, with significant corticosteroid exposure post-transplant, with increasing evidence of obesity and metabolic syndrome post-LT. Our study aimed to assess growth, body composition, and BMD in patients post-pediatric LT. Body composition and bone densitometry scans were performed on 21 patients. Pre- and post-transplant anthropometric data were analyzed. Bone health was assessed using serum ALP, calcium, phosphate, and procollagen-1-N-peptide levels. Median ages at transplant and at this assessment were 2.7 and 10.6 years, respectively. Physiological markers of bone health, median z-scores for total body, and lumbar spine aBMD were normal. Bone area was normal for height and BMAD at L3 was normal for age, indicating, respectively, normal cortical and trabecular bone accrual. Median z-scores for weight, height, and BMI were 0.6, -0.9, 1.8 and 0.6, 0.1, 0.8 pre- and post-transplant, respectively. Total body fat percentages measured on 21 body composition scans revealed 2 underweight, 7 normal, 6 overweight, and 6 obese. Bone mass is preserved following pediatric LT with good catch-up height. About 52% of patients were either overweight/obese post-transplant, potentially placing them at an increased risk of metabolic syndrome and its sequelae in later life. BMI alone is a poor indicator of nutritional status post-transplant.

Abstract
OBJECTIVES The aim of the study was to describe long-term growth postpediatric liver transplantation and to conduct bivariate and multivariate analysis of factors that may predict post-transplantation growth in children who received a liver transplant from January 1999 to December 2008 at the Hospital for Sick Children. METHODS A retrospective cohort study was conducted with follow-up of up-to 10 years post-transplantation. Mean height and weight z scores and annual differences in mean z scores were plotted against time after transplantation. A 1-way analysis of variance was conducted. Multivariate and univariate Cox proportional hazards analyses were conducted to determine factors associated with reaching the 50th and 25th percentiles for height. RESULTS A total of 127 children met eligibility criteria. The mean height z score at time of transplantation was -2.21 which by the second year post-transplantation increased significantly to -0.66 (mean increase of 1.55 standard deviation units). There were no further significant increases in mean height z score from 2 years post-transplantation until the end of follow-up at year 10. In multivariate analysis, height at transplant was the most important predictor of linear growth post-transplantation. CONCLUSIONS Children who underwent liver transplantation had significant catch-up growth in the first 2 years post-transplantation followed by a plateau phase. Increased height z-score at transplantation is the most important predictor of long-term growth.

Abstract
Pediatric liver transplantation has changed the poor prognosis for children with liver failure, some metabolic diseases and liver tumors. With the increase of survival, long-term maintenance has become a priority. Therefore, obtaining appropriate nutrition, physical growth, bone metabolism, endocrine function and psychosocial development has become one of the most important long-term objectives. This article presents an up-to-date review and recommendation of nutrition assessment, both before and after liver transplantation.

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
OBJECTIVES To describe longitudinal height, weight, and body mass index changes up to 15 years after childhood liver transplantation. STUDY DESIGN Retrospective chart review of patients who underwent liver transplant from 1985-2004 was performed. Subjects were age <18 years at transplant, survived ≥5 years, with at least 2 recorded measurements, of which one was ≥5 years post-transplant. Measurements were recorded pre-transplant, 1, 5, 10, and 15 years later. RESULTS Height and weight data were available in 98 and 104 patients, respectively; 47% were age <2 years at transplant; 58% were Australian, and the rest were from Japan. Height recovery continued for at least 10 years to reach the 26th percentile (Z-score -0.67) 15 years after transplant. Australians had better growth recovery and attained 47th percentile (Z-score -0.06) at 15 years. Weight recovery was most marked in the first year and continued for 15 years even in well-nourished children. Growth impaired and malnourished children at transplant exhibited the best growth, but remained significantly shorter and lighter even 15 years later. No effect of sex or age at transplant was noted on height or weight recovery. Post-transplant factors significantly impact growth recovery and likely caused the dichotomous growth recovery between Australian and Japanese children; 9% (9/98) of patients were overweight on body mass index calculations at 10-15 years but none were obese. CONCLUSIONS After liver transplant, children can expect ongoing height and weight recovery for at least 10-15 years. Growth impairment at transplant and post-transplant care significantly impact long-term growth recovery.

Abstract
During long-term follow-up, 18% to 67% of pediatric liver transplant recipients are overweight or obese, with rates varying by age and pretransplant weight status. A similar prevalence of posttransplant obesity has been seen in adults. Adults also develop posttransplant metabolic syndrome and, consequently, cardiovascular disease at rates that exceed the rates in age- and sex-matched populations. Posttransplant metabolic syndrome has never been studied in pediatric liver transplant recipients, and this population is growing as transplant outcomes continue to improve. Here we systematically review the literature for each component of metabolic syndrome-obesity, hypertension, dyslipidemia, and glucose intolerance-in pediatric liver transplant recipients. Their rates of obesity are similar to the rates in children in the general U.S. population. However, hypertension, dyslipidemia, and diabetes are more common than would be expected in transplant recipients according to age, sex, and obesity severity. Immunosuppressive medications are major contributors. The limitations of previous studies, including heterogeneous methods of diagnosis, follow-up times, and immunosuppressive regimens, hinder the analysis of risk factors. Importantly, no studies have reported graft or patient outcomes associated with components of metabolic syndrome after pediatric liver transplantation. However, if the trends in children are similar to the trends seen in adults, these conditions may lead to significant long-term morbidity. Further research on the prevalence, causes, and consequences of posttransplant metabolic syndrome in pediatric liver transplant recipients is needed and will ultimately help to improve long-term outcomes.

Abstract
With improved survival of orthotopic liver transplantation (OLT) in children, prevention and treatment of pre- and posttransplant complications have become a major focus of care. End-stage liver failure can cause endocrine complications such as growth failure and hepatic osteodystrophy, and, like other chronic illnesses, also pubertal delay, relative adrenal insufficiency, and the sick euthyroid syndrome. Drug-induced diabetes mellitus post-OLT affects approximately 10% of children. Growth failure is found in 60% of children assessed for OLT. Despite optimisation of nutrition, rarely can further stunting of growth before OLT be prevented. Catch-up growth is usually observed after steroid weaning from 18 months post-OLT. Whether growth hormone treatment would benefit the 20% of children who fail to catch up in height requires testing in randomised controlled trials. Hepatic osteodystrophy in children comprises vitamin D deficiency rickets, low bone mass, and fractures caused by malnutrition and malabsorption. Vitamin D deficiency requires aggressive treatment with ergocalciferol (D2) or cholecalciferol (D3). The active vitamin D metabolites alphacalcidol or calcitriol increase gut calcium absorption but do not replace vitamin D stores. Prevalence of fractures is increased both before OLT (10%-28% of children) and after OLT (12%-38%). Most fractures are vertebral, are associated with low spine bone mineral density, and frequently occur asymptomatically, but they may also cause chronic pain. Fracture prediction in these children is limited. OLT in children is also associated with a greater risk of developing avascular bone necrosis (4%) and scoliosis (13%-38%). This article reviews the literature on endocrine and skeletal complications of liver disease and presents preventive screening recommendations and therapeutic strategies.

Abstract
AIMS Currently, the main interest in childhood liver transplantation (LT) is to prevent long-term complications and optimize growth. The aim of this study is to analyze (1) nutritional status in the pretransplantation period, and (2) posttransplantation growth and associated factors in children. PATIENTS AND METHODS Eighty children were included in the study. Height (Z (H)) and weight (Z (W)) Z scores were calculated before transplantation and postoperatively at the 6th month and 1st, 2nd, 3rd, 4th, and 5th year. RESULTS Patients' Z (H) and Z (W) scores at LT were -1.6 ± 1.3 and -1.5 ± 1.4, respectively. Both Z (H) and Z (W) scores increased after LT, especially in the first 6 months, and then continued to rise gradually. Both reached beyond -1 Z score at 2nd year and -0.5 at 4th year. Age, primary diagnosis, total steroid dose (<1,000 mg), and absence of rejection episodes had positive impact on posttransplantation growth, whereas gender, immunosuppression type, surgical complications, and presence of tumor had no impact on posttransplantation growth. Age at time of LT was negatively correlated with Z (W) score at 5th year (P = 0.02, r = -0.43). Both Z (W) and Z (H) scores at time of LT were positively correlated with Z (W) and Z (H) scores and negatively correlated with ∆Z (W) and ∆Z (H) scores at 5th year. CONCLUSIONS LT is not only a modern, life-saving treatment technique but also an efficient method of facilitating growth, an indispensable component of childhood and the best indicator of health.

Abstract
One of the most critical differences between the posttransplant care of children and adults is the requirement in children to maintain a state of health that supports normal physical and psychological growth and development. Most children with organ failure have some degree of growth failure and developmental delay, which is not quickly reversed after successful transplantation. The challenge for clinicians caring for these children is to use strategies that minimize these deficits before transplantation and provide maximal opportunity for recovery of normal developmental processes during posttransplant rehabilitation. The effect of chronic organ failure, frequently complicated by malnutrition, on growth potential and cognitive development is poorly understood. This review presents a summary of what is known regarding risk factors for suboptimal growth and development following solid-organ transplant and describe possible strategies to improve these outcomes.

Abstract
Solid organ transplantation is a life-saving treatment for end-stage organ failure in children. Immunosuppressant medications are used to prevent rejection of the organ transplant. However, these medications are associated with significant adverse effects that impact growth and development, quality of life (QOL), and sometimes long-term survival after transplantation. Adverse effects can differ between the immunosuppressants, but many result from the overall state of immunosuppression. Strategies to manage immunosuppressant adverse effects often involve minimizing exposure to the drugs while balancing the risk for rejection. Early recognition of immunosuppressant adverse effects may help to reduce morbidities associated with solid organ transplantation, improve QOL, and possibly increase overall patient survival.

Abstract
Immunosuppression regimens after liver transplantation focus mainly on preventing rejection and subsequent graft loss. However, in children, morbidity and mortality rates from infections exceed those from rejection after transplant, and immunosuppression can hinder growth, renal function, and graft tolerance. We hypothesized that early steroid withdrawal, with a primary aim of TAC monotherapy would yield no penalty in terms of rejection and graft loss, while reducing risks of infection and maximizing growth. We prospectively evaluated 64 consecutive pediatric liver transplant recipients. One yr patient/graft survival was 93/90%, respectively. At one yr post-transplant, 75.4% of patients were on TAC monotherapy. No deaths or graft losses were caused by infection. Sixty-one percent of patients had at least one episode of rejection, most within three months following transplant and 3.8% were treated for chronic rejection. One non-compliant adolescent died from chronic rejection. CMV, EBV, and lymphoproliferative disease rates were 3.1%, 5.3%, 1.8%, respectively. Pretransplant and one yr post-transplant glomerular filtration rates were unchanged. One yr improved catch-up growth was observed. We conclude that immunosuppression minimization after pediatric liver transplant yields no serious complications from rejection, and might confer advantages with respect to infection, renal function, growth, and is deserving of wider application and study.

Abstract
Factors impacting linear growth following pediatric liver transplantation (LT) are not well understood. This longitudinal analysis examines predictors of linear growth impairment in prepubertal children included in Studies of Pediatric Liver Transplantation. In 1143 children with serial measurements, mean height scores increased from -1.55 at LT to -0.87 and -0.68 at 24 and 36 months post LT with minimal subsequent catch up growth observed until 60 months. Subgroup analysis of height measurements at 24 months (n = 696), 33.8% were below 10th percentile at 24 months post LT. Multivariate analysis revealed linear growth impairment more likely in patients with metabolic disease (OR 4.4, CI: 1.83-10.59) and >18 months of steroids exposure (OR 3.02, CI: 1.39-6.55). Higher percentiles for weight (OR 0.80, CI: 0.65-0.99) and height (OR 0.62, CI: 0.51-0.77) at LT decreased risk. Less linear catch up was observed in patients with metabolic disease, non-Biliary atresia cholestatic diseases and lower weight and higher height percentiles prior to LT. Prolonged steroid exposure and elevated calculated glomerular filtration rate and gamma-Glutamyltransferase following LT were associated with less catch up growth. Linear growth impairment and incomplete linear catch up growth are common following LT and may improve by avoiding advanced growth failure before LT and steroid exposure minimization.

Abstract
The theoretical risks of early SW, <3 months post-LT, and complete elimination (steroid-free LT) lie in mainly three areas, namely the risks of AGR, CGR, and the development of d-AIH that has been described in SW post-LT in children. These should be balanced against the benefits of early SW mainly manifested as effects on growth post-LT. In this paper, we focused on the clinical trials that included CS therapy risks and benefits in pediatric LT. Focusing mainly on CGR and d-AIH as risks, and the beneficial effects on growth post-LT with either low-dose CS, SW, or steroid-free regimens. Main conclusions from comparing a large number of studies are: early SW or elimination from immunosuppression protocols was neither harmful to the patient nor to the graft survival rate in the short term, the overall impression is that steroids negatively affect growth in LT recipients when used in high doses and prolonged course, and that development of d-AIH is not associated with CS therapy with evidence that chronic low dose steroids post-LT have no preventative role against d-AIH.

Abstract
AIMS The aims of this article were to report a single-center experience of pediatric liver transplantation for liver-based metabolic disorders and to compare the outcome of cirrhotic versus noncirrhotic metabolic liver disease. METHODS The medical records of 96 patients younger than 18 years undergoing transplantation for liver-based metabolic disorders from 1989 to 2005 were reviewed. RESULTS Hundred twelve transplants were performed in 96 patients at a median age of 59.7 months (range, 0-208 months). The cumulative 1-, 5-, and 10-year graft and patient survival rates were 83%, 77%, and 62% and 91%, 86%, and 82%, respectively. Acute liver failure at first presentation (hazard ratio [HR] 3.0; 95% confidence interval [CI] 1.1-8.1), age less than 1 year at time of transplantation (HR 4.6; 95% CI 1.7-12.4) and hospitalization (HR 3.2; 95% CI 1.1-9.3) were significant predictors of worse patient survival. For noncirrhotic disorders, the long-term patient (100% vs. 100%, 90% vs. 100%, and 90% vs. 75%, P=0.87) and graft survivals (93% vs. 100%, 70% vs. 100%, and 70 vs. 75%, P=0.12) at 1, 5, and 7 years for auxiliary versus orthotopic transplantation were not significantly different. CONCLUSIONS Long-term patient survival after transplantation for metabolic disorders is excellent for both cirrhotic and noncirrhotic metabolic disorders. For noncirrhotic metabolic disorders, auxiliary transplantation has similar patient and graft survival compared with orthotopic transplantation, but further research is recommended.

Abstract
The objective was to review the current state of knowledge and recommend future research directions related to long-term outcomes for pediatric liver transplant recipients. A 1-day Clinical Research Workshop on Improving Long-Term Outcomes for Pediatric Liver Transplant Recipients was held on February 12, 2007, in Washington, DC. The speaker topics were germane to research priorities delineated in the chapters on Pediatric Liver Diseases and on Liver Transplantation in the Trans-NIH Action Plan for Liver Disease Research. Issues that compromise long-term well-being and survival but are amenable to existing and new research efforts were presented and discussed. Areas of research that further enhanced the research priorities in the Action Plan for Liver Disease Research included collection of longitudinal data to define emerging trends of clinical challenges; identification of risk factors associated with long-term immunosuppression complications; development of tolerance-inducing regimens; definition of biomarkers that reflect the level of clinical immunosuppression; development of instruments for the measurement of health wellness; identification of risk factors that impede growth and intellectual development before and after liver transplantation and identification of barriers and facilitators that impact nonadherence and transition of care for adolescents.

Abstract
OBJECTIVE To evaluate the effect of end-stage pediatric liver disease and liver transplantation on growth and final height. PATIENTS AND METHODS We evaluated growth at 2 years (n = 101) and 5 years (n = 63) after pediatric liver transplantation (LTx). Twenty-three children reached final height. Height was expressed as a standard deviation score of the target height (zTH score) of each patient. RESULTS At the first 2 years after LTx, the zTH score was significantly increased from -1.7 to -1.3 SD (P < 0.05). Growth at 2 or 5 years after LTx, expressed as DeltazTH score, was positively correlated with pretransplant growth retardation (P < 0.05). In comparison with patients with noncholestatic primary liver disease, patients with cholestatic primary liver disease were more severely growth retarded before LTx (zTH score -2.0 vs -1.2 SD, P < 0.05) and had better growth in the first 2 years after LTx (DeltazTH score +0.6 vs -0.1 SD, P < 0.05). Twelve of the 23 patients had a final height below -1.3 SD of their target height. CONCLUSIONS Growth retardation is common in children before LTx, particularly in children with an underlying cholestatic disease. After LTx, catch-up growth was partial and was prominent only in cholestatic children who had been severely growth retarded before LTx. After LTx during childhood, approximately 50% of patients reach a final height lower than -1.3 SD of their genetic potential.

Abstract
This study evaluated changes in growth parameters after pediatric heart transplantation and identified factors associated with the changes after pediatric heart transplantation (OHT). We retrospectively evaluated the somatic growth of 46 children <11 yr of age who underwent OHT for changes in weight, height, and BMI. The patient age range was 3.5 months to 10.7 yr. Gain in Z score for weight and BMI was significant at six months post-OHT (mean weight Z score changed from -1.1 to -0.1 and mean BMI Z score changed from -0.1 to 1.3; p < 0.001). After six months post-OHT, there was no further significant change in weight or BMI Z score. Height Z score did not show significant change from pre-OHT at six months, one yr, or two yr post-OHT. Eight patients (17%) became overweight during the two-yr follow-up period as evidenced by a BMI Z score > 2. Multivariate analysis showed length of steroid treatment as a predictor for negative height Z score change, and age at transplant as a predictor for positive height Z score change. Post-OHT, weight significantly increases without proportional increases in height, resulting in a significant proportion of these children becoming obese. Length of steroid therapy is negatively related to the "catch-up" linear growth following OHT.

Abstract
We evaluated the growth curves of children with BA after LDLT, and identified factors influencing growth velocity one-yr after LDLT (DeltaZ). The clinical data of 51 children with BA, who had an LDLT at our center from 2001 to 2005, were retrospectively reviewed. The Z scores for height and weight, and DeltaZ were studied. The correlation between DeltaZ and various clinical factors was evaluated statistically. Multivariate stepwise analyses were performed for DeltaZ. The average height and weight Z scores at the time of LDLT were -1.34 +/- 1.36 (+/-s.d.) and -0.78 +/- 1.15, respectively. Among 30 BA recipients with stable liver function after transplant, weight returned to normal one-yr post-transplantation. However, height did not return to normal even by the third post-transplantation year. On multivariate analyses, 73% of the variance in height DeltaZ could be accounted for by factors such as standardized height at the time of LDLT (proportion of variance: 38%), number of steroid pulse treatments (17%), donor age (10%), and the presence of HVS (9%). Fifty-four percentage of the variance in weight DeltaZ could be accounted for by factors such as standardized weight at the time of LDLT (37%) and the total steroid dose given (17%). Height and weight status at the time of LDLT likely have the strongest impact on DeltaZ. Additional factors include steroid exposure, age of the living donor, and presence of HVS, all of which should be considered to improve post-transplantation growth.

Abstract
Pediatric liver transplant patients are now routinely surviving 10 years or more. Beyond the first year after transplant, surgical biliary or vascular complications are rare, and the incidence of acute rejection episodes falls precipitously. Attention is turning to minimizing the toxicity of immunosuppressive regimens and their potential negative impact on growth, bone health, cognitive development, renal function, and quality of life. Innovative combinations of immunosuppressive medications are being used as initial management after transplantation to minimize acute rejection and allow rapid weaning of corticosteroids and reduction in maintenance levels of calcineurin inhibitors. The substitution of potentially less toxic immunosuppressive agents, such as mycophenolate mofetil and rapamycin, is being studied in patients who develop renal dysfunction. A major current emphasis is on defining the natural history of long-term graft injury and elucidating histopathologic changes that mimic autoimmune chronic active hepatitis but are likely a form of chronic rejection due to production by the recipient of antibodies to foreign graft antigens. As patients survive longer, we are seeing various forms of immune dysregulation engendered by the presence of the graft and chronic immunosuppression of the host. By defining the resulting patterns of graft injury and understanding their immunopathogenesis, we can devise rational adjustments in immunosuppression that will preserve graft function and maximize graft life.

Abstract
The Pediatric end-stage liver disease (PELD) score was developed as a measure of the severity of chronic liver disease that would predict mortality or children awaiting liver transplant. From multivariate analyses a model was derived that included five objective factors which together comprise the PELD score. The factors are growth failure, age less than 1 year, international normalized ratio (INR), serum albumin and total bilirubin.

Abstract
PURPOSE We studied the age-related changes in graft livers, and their impact on post-transplantation liver function and the growth of young recipient rats. METHODS Rats aged 11-68 weeks old were studied as controls to assess liver histology, liver function, and body weight. We performed orthotopic liver transplantation using Kamada's cuff technique without arterial reconstruction. Young rats aged 11 weeks were randomized to receive livers from either 11-week-old donors (YD group) or 52-week-old donors (OD group). Recipient rats were killed 0, 8, or 16 weeks after surgery and we assessed the same variables as in the controls. RESULTS We confirmed an age-related increase in the average size of hepatocytes and their nuclei. These age-related changes persisted and progressed in the graft liver after transplantation. There were no significant differences in the levels of serum transaminases or total bilirubin between the YD and OD groups, but the serum albumin level was significantly lower in the OD group. The YD group grew normally, whereas the OD group recipients lagged significantly in gaining body weight. CONCLUSION We found that 52-week-old grafts transplanted into 11-week-old recipients resulted in deficient growth and a decline in serum albumin, suggesting that grafted old livers fail to produce enough protein to meet the demands of growth adequately.

Abstract
The use of split-liver (SL) allografts continues to be an excellent option for many pediatric recipients. Patient and graft survival with this graft type are comparable to patient and graft survival with whole organ grafts. Quality-of-life issues, specifically growth, for SL recipients have not been compared to those of recipients of more conventional whole-organ recipients. Pediatric recipients of SL and whole allografts at 2 institutions were identified. Height, z score, and delta z score were calculated for all recipients for each year after transplant. Between 1995 and 2004, 201 pediatric liver transplants were analyzed. Data were collected on 39 split-graft recipients and 36 whole-size recipients. Only subjects 3 years or younger were included in the study. Growth retardation was present in all recipients at transplant. Height z score post split and whole-size transplant were not statistically different at 1- (P = 0.65), 2- (P = 0.13), and 3-year (P = 0.32) anniversaries, respectively. Catch-up growth was present only in recipients of split grafts. In conclusion, the use of split grafts as opposed to whole-size grafts revealed no significant differences in terms of linear growth. Our report indicates that split-liver transplantation does not impair recipient growth.

Abstract
The aim of our study was to analyze growth in children who underwent LDSB. The question was whether these children obtain linear growth and improvement of the Z-score for height and weight after the transplant. Three children with a mean age of 24 months underwent living-donor intestinal transplantation with 150 cm of terminal ileum. At a mean follow-up of 27 months height increased from 82.5 to 97.5 cm although Z-score for height did not improve, -2.679 to -2.675. Mean weight increased from 11.4 to 14.2 kg while Z-score for weight went from -1.916 to -2.409. Although these data are pertinent to only three children and the follow-up is slightly longer than two yr, it appears that while long-term survival and independency from TPN is achieved, only linear growth might be expected and catch-up growth does not occur.

Abstract
BACKGROUND Children with primary hyperoxaluria type 1 (PH1) often develop severe growth failure, which is related to metabolic and endocrine consequences of chronic renal failure, and/or oxalate deposition in bone and cartilage. Combined liver and kidney transplantation (LKT) corrects the underlying metabolic defect and restores renal function in these children. METHODS We therefore analyzed longitudinal growth of 24 children with PH1 who underwent LKT at nine European centers. Mean age at LKT was 8.9 years, and mean duration of follow-up was 5.7 years. RESULTS After LKT mean standardized height tended to increase from -1.79 SD to -1.47 SD until last observation. Mean adult height amounted to 167 cm and 158 cm in boys and girls, respectively. At last observation, seven out of 24 patients were stunted. Within the whole study population, the degree of catch-up growth after LKT was positively associated with degree of stunting at the time of LKT and negatively associated with prednisolone dosage explaining together 39% of the overall variability. CONCLUSIONS Combined LKT does not induce true catch-up growth in the majority of children with PH1. Due to the preexisting growth retardation at the time of LKT, one third of patients end up with a reduced final height.

Abstract
Growth is an important feature of childhood, but it is usually impaired before and after organ transplantation. Modest catch-up growth often occurs after renal transplantation. Nevertheless, patients remain short due to the effects of steroids used for immunosuppression. Children with chronic liver failure are also growth impaired, although not to the same extent. They also frequently have poor catch up growth after transplantation, again due to steroids. There are several randomized controlled clinical trials reporting growth hormone (GH) use after renal transplantation. These consistently show a beneficial effect of GH on linear growth. Patients with histories of frequent acute rejections before GH may have increased risk of acute rejection during treatment. Few data exist on liver transplant patients, although GH also appears effective. GH use may be safe and effective for renal transplant recipients who have been stable without acute rejection episodes. There needs to be long-term study of GH use in liver and renal transplant patients. It is critical to focus efforts on improving growth in renal failure before transplantation through GH use and to improve posttransplant growth in all recipients by minimizing steroid exposure.

Abstract
Intestinal transplantation has been more frequent in children with intestinal failure. However, the growth after intestinal transplantation has not been well documented. The demographics, transplant information, postoperative complications, heights, and weights were obtained retrospectively from medical records on 23 children who underwent intestinal transplantation. Z-scores were calculated from the STAT Growth-BP, based on Centers for Disease Control and Prevention growth chart (2000). Transplantations were performed between 1999 and 2004. Patient median age was 1.1 years (range 0.5 to 6.9 years). Twelve were boys and 11 girls. Seventeen children received multivisceral transplantations, one modified multivisceral transplantation, and five isolated intestinal transplantations. Baseline immunosuppression consisted of tacrolimus and corticosteroids. Daclizumab was used as induction agent in 18 patients; alemtuzumab, in five patients. Median pretransplant Z-scores were median -1.67 (n = 23) in weight, and median -3.36 (n = 21) in height. Pretransplant growth was significantly retarded. We analyzed significantly retarded patients with Z-score <-2.0. The change of weight Z-score from pretransplant was: 1.25 at 6 months (n = 11), 1.46 at 12 months (n = 10), and 2.21 at 24 months (n = 7). The change of height Z-score: 1.9 at 6 months (n = 16), 1.42 at 12 months (n = 13), and 1.51 at 24 months (n = 10). Z-score significantly improved (P < .002, ANOVA). Among the analyzed factors sex, age at transplant, length of stay, and rejection within 6 months, were not associated with catch-up growth. Children with retarded growth showed significant catch-up after successful intestinal transplantation.

Abstract
In order to determine the influence of living donor liver transplantation (LDLT) on long-term growth, we studied the progress of 36 children who had survived more than 5 yr after LDLT from 1994 to 1999. The median age at the transplantation was 1.5 yr (range: 6 months-15 yr) and the median follow-up period was 6.5 yr (range: 5-9 yr). A height standard deviation score (zH) was analyzed for each patient according to medical records. Significant catch-up growth occurred within 2 yr after LDLT with a mean zH changing from -1.2 to 0.0 and was maintained for up to 7 yr post-transplantation (zH-0.1). Younger children (<2 yr) were more growth-retarded at the time of LDLT, but showed higher catch-up growth rates and their final zH was greater than that of older children. Children with liver cirrhosis were more growth-retarded at the time of LDLT, but showed significant catch-up growth and their final height was similar to children with fulminant hepatitis. Growth in children who experienced significant hepatic dysfunction after LDLT was not significantly different from those without graft dysfunction. There was no difference between the types of immunosuppressants used. Our finding suggests that LDLT can result in adequate catchup linear growth, and this effect can persist even after 7 yr post-transplantation.

Abstract
Improving a patient's quality-of-life (QOL) post-liver transplantation is of great importance. An aspect of improved QOL is the restoration of normal growth patterns in pediatric patients. To describe the post-transplantation growth patterns of 72 children included in the National Institute of Diabetes and Digestive and Kidney Diseases - Liver Transplantation Database (NIDDK-LTD), multilevel models were used, according to which children who waited more than a year for transplantation were smaller, compared with age and sex matched peers, at transplantation than children who waited less than a year while children who were growth retarded at transplantation experienced a larger yearly comparison height increase than children who were not growth retarded. The analysis also showed that boys older than 2 yr and younger than 13 yr at transplantation and girls older than 2 yr and younger than 11 yr at transplantation were significantly less growth retarded at transplantation than boys and girls under the age of 2 yr at transplantation.

Abstract
BACKGROUND Because the results of short-term recombinant human growth hormone (rhGH) treatment in children with growth impairment after liver transplantation (LTx) have been promising, we have studied the long-term effects of rhGH on growth and graft function after LTx. METHODS Indications for rhGH treatment were height standard deviation score (hSDS) below -2.0 or growth velocity SDS below 0 and LTx at least 18 months before inclusion. Eight growth-retarded children were treated with rhGH for more than 5 years. RESULTS During the first year, median growth rate improved from 3.3 to 7.0 cm/year. In the second and third year, growth velocity remained high at 6.6 cm/year and 6.2 cm/year, respectively (P=0.008). In the fourth year, median growth velocity started to decline but still remained above baseline during the fifth year of treatment (4.2 cm/year). The median hSDS improved from -3.6 to -2.7. During the rhGH treatment, no acute rejection episodes were detected, and graft function remained stable in all except one patient. She was diagnosed with chronic rejection in the third year of rhGH treatment. The patient had elevated liver enzymes and abnormal liver function tests already before rhGH treatment. CONCLUSIONS The efficacy of rhGH treatment is sustained after the first year in liver-transplant children with non-GH-deficient growth retardation. Because of a potential risk of side effects, close monitoring of these patients is required.

Abstract
1. The PELD score accurately predicts the 3 month probability of waiting list death for children with chronic liver disease. 2. Comparing pre and post PELD and MELD implementation, the percent of children receiving deceased donor livers increased and the percent of children dying on the list decreased after PELD/MELD implementation. 3. Excluding children transplanted at status 1, the largest percentage of children are transplanted at a PELD score < 10. 4. Before MELD/PELD 48% of all children receiving deceased donor organs were transplanted at status 1, compared to 41% in the PELD/MELD era. Wide regional variation occurs.

Abstract
Adult stature and peak bone mass are achieved through childhood growth and development. Multiple factors impair this process in children undergoing solid organ transplantation, including chronic illness, pretransplant osteodystrophy, use of medications with negative impact on bone, and post-transplant renal dysfunction. While growth delay and short stature remain common, the most severe forms of transplant-related bone disease, fracture and avascular necrosis, appear to have become less common in the pediatric age group. Osteopenia is very prevalent in adult transplant recipients and probably also in pediatrics, but its occurrence and sequelae are difficult to study in these groups due to methodological shortfalls of planar densitometry related to short stature and altered patterns of growth and development. Although the effect on lifetime peak bone mass is not clear, data from adult populations suggest an elevated long-term risk of bone disease in children receiving transplants. Optimal management of pretransplantation osteodystrophy, attention to post-transplant renal insufficiency among both renal and non-renal transplant patients, reduction of steroid dose in select patients, and supplementation with calcium plus vitamin D during expected periods of maximal bone loss may improve bone health. Careful research is required to determine the role of bisphosphonate therapy in pediatric transplantation.

Abstract
BACKGROUND The reported incidence of catch-up growth following orthotopic liver transplantation (OLT) ranges widely, from 0% to 97%. OBJECTIVE We undertook bivariate analysis of multiple factors that might affect post-OLT growth in children undergoing OLT, and described the results with different parameters used to determine catch-up growth. METHODS Eighty patients met the inclusion criteria. RESULTS Catch-up growth occurred in 14% during the first 6 months, 15% at 1 year, 39% at 2 years, 16% between 3 and 6 years, and 16% after 6 years post-OLT. The earlier catch-up growth was shown in metabolic diagnosis, patients over 10 years old and those without steroids at 1 year post-OLT. CONCLUSIONS It is difficult to determine an acceptable definition of catch-up growth. We suggest that Zvel score > or =0 is the best parameter to evaluate catch-up growth, since the results are more normally distributed. Patients with prednisone withdrawal later than 1 year post-OLT and those with diagnosis of hepatitis and cirrhosis showed the slowest catch-up growth.

Abstract
Studies of Pediatric Liver Transplantation (SPLIT) was initiated in 1995 for the purpose of collecting comprehensive data from children undergoing liver transplantation. As of May 31, 2002, 1761 children were registered in SPLIT from 38 participating centers in the United States and Canada. This report focuses on the demographics, primary diagnoses, clinical indications for transplant, and probability of obtaining liver transplantation for the 1187 children receiving a liver transplant after registration in SPLIT. Demographic information is also provided for the 1092 children who received their first ever liver transplantation. For this cohort, we also describe immunosuppressive practices at the time of transplant, and how the use of different medications changes with time.

Abstract
Orthotopic liver transplantation (Tx) has improved survival in infants with extrahepatic biliary atresia (BA) when portoenteroanastomosis fails. Symptoms leading to Tx include liver failure, poor quality of life and growth failure. The objective of the study was to determine catch-up growth in children with BA. Medical records and growth data of 36 patients (24 girls) who received a Tx due to BA were analyzed. Thirty-two patients completed 3 yr and 15 patients 7 yr of follow-up after Tx. At Tx, the median age was 2.7 yr (range 0.7-12.6) and mean height Z score (+/-s.d.) was -1.56 (+/-1.3). Patients were divided in two groups according to age at Tx: group I (n = 10), younger than 1.0 yr, and group II (n = 26) older than 1.0 yr. Median age (range) at Tx in group I was 0.8 yr (0.7-1.0) and in group II it was 3.35 yr (1.25-12.6). Thirteen patients (nine in group I) were receptors of living related donors. We evaluated linear growth, liver and renal function, immunosuppressive regimen and allograft rejection episodes. We did not find any significant differences in allograft or renal function, immunosuppressive therapy and number of acute rejection episodes or height Z score at Tx, second and third year post-Tx between both groups. The mean height Z score at Tx in group I was -1.61 and in group II -1.54; at the second year, group I -0.66 and group II -1.08; at the third year, group I -0.17 and group II -0.85; and at the seventh year (total group) -0.3. However, the height gain at the third year was better in group I than in group II (p < 0.01, t-test). Height Z score at the third year improved more than 1 SDS in seven out of eight patients in group I and in only nine out of 24 in group II (odds ratio 11.6). We also found a correlation between height gain at the third year and age at Tx (r-0.65) and between height gain at the third year and height Z score at Tx (r-0.54) (Pearson, p < 0.05). Children with BA who are transplanted before 12 months of age presented better catch-up growth without change survival and morbidity. Orthotopic liver Tx improves survival and also enables height gain in these children.

Abstract
To examine the effects of cardiac transplantation on skeletal maturation and linear growth, we retrospectively evaluated annual bone age determinations and growth parameters of pediatric cardiac transplant recipients followed at our center. Included in the analysis were records of 86 patients (32 females) who had received a cardiac transplant at our institution between 1984 and 1998. Bone age delay of > or =12 months was apparent in 38.5% at the time of transplantation. At some point in their post-transplant course, 23 patients (29%) had one or more bone age measurements that were > or =36 months delayed with respect to chronological age. Children transplanted before age seven and those with a pretransplantation diagnosis of cardiomyopathy experienced the most significant decrement in skeletal maturation after transplantation. High cyclosporin A levels and low body mass index were the only parameters found to be associated with delayed bone age. Although the majority of children grew at a normal rate after transplantation, height Z scores and height age were adversely affected regardless of the type of heart disease or the age at transplantation. The pathogenesis of both delayed skeletal maturation and growth retardation in this population warrant further investigation.

Abstract
The following is a summary report of an extensive review of the literature from 1966 to 2001 on growth and development in children receiving kidney, liver and heart transplants. The literature was assessed for relevancy to current clinical practice and for reliability and generalizability of the inferences based on the study design, controls, sample size, age distribution, confounding factors, use of standardized instruments, and consistency with other findings. While studies on growth are included in the review, the main emphasis is on research in cognitive and psychosocial development since these areas have been far less thoroughly studied and contain various methodological deficiencies. On the basis of the literature review both general methodological recommendations and specific recommendations for future research studies are made.

Abstract
UNLABELLED The functional status and health-related quality of life (HRQOL) of children who survive liver transplantation (LT) have not been well documented. The purpose of this study was to determine the functional status and HRQOL in this population using a validated measure for children, the Child Health Questionnaire-Parent Form 50 (CHQ-PF50). METHODS The CHQ-PF50 instrument was completed by the parents of 55 children who agreed to participate in a mailing survey. Subscale scores for the sample were compared with those of a published normal population (n = 391). RESULTS Study sample characteristics were: 87% Caucasian, 54.5% female, mean age at survey was 9.6 years (range, 5-17 years). Responding caregivers were 95% biologic parents and 93% female. Compared with the normal population, LT recipients had lower subscale scores for general health perceptions (P < 0.0005), emotional impact on parents (<0.0005) and disruption of family activities (0.0005). The mean physical summary score of the LT recipients was lower than that of the normal population 48.1 +/- 12.1 (P = 0.005), but the mean psychosocial summary score was similar 48.8 +/- 11.9 (P = 0.156). Within the LT population, the original diagnosis (biliary atresia vs. other), type of LT (living donor vs. cadaveric), age at LT, z score for height, and hospital days did not significantly influence any of the subscale scores. CONCLUSIONS Children who have survived LT have functional outcomes in the physical domain that are lower than those of normal children. Self-esteem and mental health in this group appeared normal. The parents in this sample experienced more emotional stress and disruption of family activities than did parents in a normal population.

Abstract
BACKGROUND We investigated the cognitive status and quality of life (QoL) in the late postoperative phase of children who had undergone liver transplantation (LTx). METHODS The sample consisted of 29 children who had undergone LTx at our center. The children were at least 6 years of age and had received the transplant between 3 and 10 years (mean 6.4 years) previously. In 16 of the 29 children, a living-related transplantation had been performed. Cognitive function was assessed with the three subscales of the Kaufman Assessment Battery for Children (K-ABC): the sequential processing scale, simultaneous processing scale, and achievement scale. QoL was measured with a specific questionnaire for children. RESULTS The children scored below the population mean but within the normal range on all subscales of the K-ABC, except for the sequential processing scale, on which the children scored significantly below the norm and below their own performance on the simultaneous processing scale. Scores were below average for everyday and psychic functions and in the normal range for social and physical functions on the QoL questionnaire. Age at transplantation and achievement in the K-ABC were highly negatively correlated. A multiple regression analysis revealed that age and height at transplantation, and also to a lesser degree the type of transplantation, predict the level of cognitive functioning in the late postoperative phase. CONCLUSION We conclude that the cognitive functions and QoL of children in the late postoperative phase who have undergone LTx are at the lower end of the norm in the long-term follow-up. Children who are younger and more physically developed at the time of transplantation will have a better mental-development prognosis.
