Abstract
BACKGROUND As long-term survival of pediatric liver transplant recipients increases, the assessment of physical, psychological, and social well-being becomes more important. METHODS In this retrospective analysis, 120 young adult patients (age ≥18 y) who underwent liver transplantation in childhood were studied. Patients with ideal outcome were defined as patients with perfect graft function, with no complications from the immunosuppressive medication, no late retransplantation, and no steroid treatment. Also, the patients' drug adherence and their psychosocial situation were assessed. RESULTS After a median follow-up of 19 y, only 16.7% of the patients (mean age: 26.5 y) were considered patients with ideal outcome. The main reasons precluding ideal outcome were chronic kidney disease (38.3%), elevated liver enzymes (33.3%), and arterial hypertension (31.7%). Ideal outcome decreased over time from 54% to 42%, 26%, and 8% at 10-, 15-, 20-, and 25-y follow-up, respectively. Reduced drug adherence was noted in 24.8% of patients and associated with a significantly higher prevalence of donor-specific antibodies class II ( P = 0.015), elevated transaminases ( P = 0.010), and chronic rejection ( P < 0.001). Also, 15% of patients had a psychiatric disease, mainly depression. CONCLUSIONS The morbidity of young adults who underwent liver transplantation as children was high and increased over time. The majority developed complications from immunosuppression or chronic graft dysfunction. More than 1 in 7 patients had a psychiatric disease and 1 in 4 was not perfectly drug adherent. Therefore, immunosuppressive treatment and psychological care should be optimized for these particularly vulnerable patients.

Abstract
OBJECTIVE Pediatric recipients of liver transplantation (LT) often report lower Health-Related Quality of Life (HRQOL) than healthy controls when assessed on generic HRQOL measurement tools. The recent addition of the Pediatric Liver Transplant Quality of Life (PeLTQL), a novel disease-specific HRQOL instrument for pediatric LT recipients, into the clinical armamentarium of tools now routinely available to clinical care teams, provides the unique opportunity to identify disease-related challenges in children who have undergone this life-saving intervention. This study assesses HRQOL in pre-adolescent aged patients with a primary diagnosis of biliary atresia (BA) who underwent LT as an infant, using both generic and disease-specific HRQOL instruments validated for children. We also examined modifiable factors associated with HRQOL after pediatric LT. METHODS HRQOL was the primary outcome of this study assessed using the disease-specific PeLTQL and the generic Pediatric Quality of Life Inventory 4.0 (PedsQL). Exposure variables of interest included medication status (e.g., monotherapy, dual therapy) and participation in sports. RESULTS A total of 70 (56% female, mean age 9.89 ± 1.25 years) pediatric LT recipients (mean interval since LT was 9.0 ± 1.26 years) comprised the study cohort. LT recipients reported significantly lower PedsQL Scores relative to the general population. Immunosuppression monotherapy was associated with higher patient-reported PeLTQL Scores, and sports participation was associated with higher parent-reported PedsQL Scores. CONCLUSIONS Pre-adolescents who underwent LT as an infant with BA, self-report low HRQOL on both disease-specific and generic HRQOL tools. Further research targeting sports participation and simplifying immunosuppression may further optimize quality of life years restored by life-saving LT.

Abstract
PURPOSE Adherence to the medical regimen after pediatric liver transplantation is crucial for good clinical outcomes. However, the existing literature provides inconsistent evidence regarding the prevalence of and risk factors for nonadherence to the medical regimen after pediatric liver transplantation. This study aimed to investigate such nonadherence after pediatric liver transplantation and risk factors associated with this nonadherence using findings of reported studies. METHODS The electronic databases of Excerpta Medica, Ovid Technologies, PubMed and WanFang Data were searched using the keywords "adherence", "liver transplant" and "paediatric". Additionally, relevant references cited in related studies were used to obtain original articles. Using 22 original articles, data regarding nonadherence to the medical regimen after pediatric liver transplantation were quantitatively combined, and risk factors associated with nonadherence were qualitatively identified. Average rates of nonadherence in four areas of medical regimens were calculated. The heterogeneity of the included original articles was also analyzed. When I 2>50 and P<0.05, a random effects model was used; otherwise, a fixed effects model was used. Moreover, Egger's and Begg's tests were used to evaluate publication bias, if any, and original articles with P>0.05 were considered to have no publication bias. RESULTS The clinical attendance nonadherence rate was 45% (95% confidence interval [CI]: 39-51), global nonadherence rate was 17% (95% CI: 13-21) and immunosuppression non-adherence rates were 39% (95% CI: 26-52) and 34% (95% CI: 30-39) for cyclosporine and tacrolimus, respectively. Risk factors included older age of the pediatric patient, low family cohesion, poor social functioning, poor mental health and single-parent family. CONCLUSIONS The nonadherence rate in pediatric liver transplantation is high. Therefore, intervention on the basis of risk factors, such as mental health and family function, may be necessary. Moreover, a standard technique for assessing nonadherence to the medical regimen after pediatric liver transplantation, comprising as many dimensions as possible, is required in order to be more objective and comprehensive when assessing nonadherence.

Abstract
INTRODUCTION Posttransplantation diabetes mellitus (PTDM) increases the risk of cardiovascular disease, graft loss, and decreased survival. Follow-up treatment after solid organ transplantation (SOT) needs to focus on, inter alia, maintaining balanced glucose metabolism. This study aimed to ascertain the prevalence of PTDM and describe patient characteristics in the large DPV (Diabetes Patienten Verlaufsdokumentation) pediatric diabetes database. METHODS DPV data of 71 902 patients from the January 01, 1995 to January 04, 2015 period were analyzed for patients with and without cystic fibrosis (CF) after SOT (kidney, liver, heart, and lung). Multivariable analysis served to assess differences between SOT patient groups at risk for developing diabetes. RESULTS Out of 109 SOT patients, 51 had CF; 72.5% received steroids and 62% were additionally given tacrolimus. PTDM developed in 45% of CF patients and 12% of non-CF patients. SOT patients were older at diabetes onset (mean age, 12.50 ± 3.98 years), shorter (height z-score, -1.67 ± 1.25), and lighter (weight z-score, -1.59 ± 1.57) than non-SOT diabetes patients (P < 0.01). With transplantation, glycated hemoglobin (HbA1c) was significantly lower and treatment for hypertension and dyslipidemia was increased. Among SOT patients, weight and body mass index (BMI) z-scores were significantly lower in patients with CF-related diabetes (P < 0.05). CONCLUSIONS SOT was present in 6.6% of children with diabetes, and this might aggravate the risk of cardiovascular disease in populations with already increased rates of hypertension and dyslipidemia. Dystrophy and short stature were also present, particularly in transplant recipients with CF and diabetes. Comorbidities and long-term consequences call for multidisciplinary collaboration.

Abstract
BACKGROUND & AIMS Survival rates after liver transplantation (LT) in paediatric recipients have significantly improved over time. However, data regarding outcomes after transition from Paediatric to Adult Healthcare Service (AHS) are still lacking. Therefore, we aimed to prospectively evaluate the outcome of LT recipients after transition, to access patients' non-adherence and identify potential risk factors for non-adherence. METHODS All consecutive adolescent LT recipients moving to the AHS at Padua University Hospital were evaluated between 2010 and 2015. Demographic data, liver function tests, incidence of acute or chronic rejection episodes and adherence to medical prescription, were prospectively evaluated. An educational pilot study was implemented since 2015 to foster adherence during transition. RESULTS In all, 32 patients (M/F 16/16, median age: 23 years) were evaluated. Median interval time between LT and transition was 15 years (range: 1-26 years). The main indication for LT was biliary atresia (31%), whereas immunosuppression regimen was tacrolimus-based in 75%. After a median follow-up of 29 months (range: 12-83), no significant modifications of liver function tests were observed. Biopsy-proven chronic rejection was diagnosed in 6/32 (18%) of patients, who had higher standard deviation of tacrolimus trough level than patients without (1.5 vs 1, P = .03). Non-adherence was reported in 8/32 (25%) of patients and was significantly associated with alcohol consumption (P = .003). Patient and graft survival were 96% and 93%, respectively. CONCLUSIONS Adolescent LT patients who undergo transition to the AHS have good long-term outcomes. However, a multidisciplinary approach aiming at fostering adherence should be used.

Abstract
Physical Activity (PA) plays an important role in the physical and psychosocial health of children and is beneficial in the treatment and prevention of comorbidities associated with transplantation. Despite this, PA participation in pediatric liver transplant recipients remains low compared to healthy peers. This qualitative-focused mixed-methods study explored the PA experiences and parental perception of these experiences, including perceived facilitators and barriers to PA in children post-liver transplant. Eighteen participants (9 children [median age 10.8 years] and 9 parents) took part in semi-structured interviews and completed the PedsQL Multidimensional Fatigue Scale and PAQ. Most children reported they were physically active (PAQ median 3.08 [IQR] 2.60-3.51), participating in PA for its enjoyment, regardless of their level of motor proficiency. Levels of fatigue (median 65.28 [IQR] 56.25-90.97) were higher than healthy norms and impacted PA participation in some children. Children and parents perceived PA as central to post-transplant recovery and valued its social and mental health benefits; however, parents struggled with ongoing uncertainty and perceived physical vulnerability of their child. This study indicates the need for continuing PA support and education and provides valuable information for family-centered interventions to increase PA and improve health outcomes in children post-transplant.

Abstract
With improved survival rates after pediatric liver transplantation (LT), attention is targeting improving the health-related quality of life (HRQOL) as an outcome metric. We conducted a systematic review of the literature to examine HRQOL after pediatric LT, focusing on assessment tools and factors associated with HRQOL. A literature search was conducted through PubMed, Web of Science, Ovid, and Google Scholar for all studies matching the eligibility criteria between January 2004 and September 2016. Titles and abstracts were screened independently by 2 authors and consensus for included studies was achieved through discussion. A total of 25 (2 longitudinal, 23 cross-sectional) studies were reviewed. HRQOL in pediatric LT recipients is lower than healthy controls, but it is comparable to children with chronic diseases or other pediatric solid organ transplant recipients. Domain scores were lowest in school functioning on the Pediatric Quality of Life Inventory (PedsQL) Generic Core Scale 4.0 and general health perception on the Child Health Questionnaire, the 2 most commonly used generic HRQOL instruments. Identified predictors of poor HRQOL include sleep disturbances, medication adherence, and older age at transplantation. Two recently validated disease-specific HRQOL tools, Pediatric Liver Transplant Quality of Life tool and the Pediatric Quality of Life Inventory 3.0 Transplant Module, have enabled enhanced representation of patient HRQOL, when used in conjugation with generic tools. Heterogeneity in study design and instruments prevented a quantitative, meta-analysis of the data. In conclusion, continued optimization of durable outcomes for this population mandates prioritization of research focusing on the gap of targeted intervention studies aimed at specific HRQOL subdomains and longitudinal studies to predict the trajectory of HRQOL over time.

Abstract
The health benefits of PA are well established for healthy and chronically ill children. This study objectively measures physical fitness and PA levels in children PLT and explores potential correlates and perceived barriers impacting their PA. A total of 23 children (16 females, mean 14.01 ± 2.49 yrs) >1 yr PLT were assessed for peak oxygen consumption (VO2 peak), muscle strength, endurance, and flexibility. MVPA and steps/day were determined with accelerometry. Additionally, SE, perceived fatigue, and barriers and benefits of PA were examined. VO2 peak (mean 33. 2 ± 7.61 mL/kg/min; 77.0 ± 15.6% predicted) and PA (average 6841 ± 2299 steps/day) were below healthy norms. MVPA (31.6 ± 16.1 min/day) was lower than national guidelines. Six participants (30%) attained criterion standards for abdominal strength and one participant (5%) for push-ups. Fatigue and SE were lower than reported levels in healthy children. A commonly perceived barrier to PA was "I am tired." A positive correlation was shown between SE and MVPA (r = 0.57, p = 0.007), SE and fatigue (r = 0.54, p = 0.01), and PELD score and fatigue (r = 0.66, p = 0.007). Children PLT demonstrate below normal levels of PA and aerobic capacity. SE is a modifiable correlate of their PA. Further investigation of the impact of PA correlates can guide the development of future innovative PA intervention strategies in children PLT.

Abstract
Arterial hypertension is a major risk factor for cardiovascular disease after solid organ transplantation, emphasizing the need for blood pressure (BP) monitoring. The authors studied 24-hour ambulatory BP monitoring (ABPM) parameters (index, load, dipping) and their predictive value with regard to hypertension as well as correlations with graft function and metabolic parameters such as obesity and dyslipidemias. The ABPM profiles of 111 renal, 29 heart, and 13 liver transplant recipients were retrospectively analyzed 5 to 10 years after transplant (median 5.1 years). The BP profiles among the different transplant groups were similar. The BP index and load were abnormal especially at nighttime and the nocturnal BP dipping was often blunted (in 49% to 83% of the patients). The BP variables were found to be equally valued when assessing hypertension. BP load of 50% instead of 25% seems to be a more adequate cutoff value. The BP variables correlated poorly with the metabolic parameters and kidney function. Antihypertensive medication did not notably change the ABPM profile in renal transplant recipients. Hypertension, including nocturnal hypertension, is present in children receiving solid organ transplant, underlining the importance of use of ABPM in the follow-up of these patients.

Abstract
OBJECTIVES Survivors of pediatric liver transplantation are at risk for developing complications related to posttransplant immunosuppressive medications. Withdrawal is possible in selected patients but carries the risk of graft rejection and loss. We modeled the effect of withdrawing immunosuppressive medications on survival, cost, and quality-adjusted life-years (QALYs) in a hypothetical cohort of pediatric patients who received transplantation for biliary atresia with stable liver enzymes and no recent episodes of rejection, and who were free from immunosuppression-related adverse effects. METHODS A decision analysis tree was developed, and Monte Carlo simulations were used to track patients through the model during a 10-year time course with 1-year cycles. Data from the literature were used to assign probabilities to major clinical events and preference-based utility scores to the values of health outcomes. One-way and probabilistic sensitivity analyses were used to evaluate the impact of uncertainty. RESULTS Patients following the withdrawal strategy had a 10-year survival rate of 95.8% and experienced 8.61 QALYs versus 88.6% survival and 8.01 QALYs for those taking immunosuppressive medications. Each additional QALY is attained at a cost of -$18,992.41 and was therefore cost saving. CONCLUSIONS Patients in our model who had their immunosuppression withdrawn had improved survival and QALYs with lower costs. Although every effort was made to validate the model, it is limited by the accuracy of the underlying assumptions. Therefore, clinical trials are needed to determine predictors of successful immunosuppression withdrawal to allow for personalization of medication regimens.

Abstract
Solid organ transplantation is the treatment of choice in children with end-stage organ failure. With improving methods of transplant surgery and post-transplant care, transplantation is more frequently performed worldwide. However, lifelong and non-specific suppression of the recipient's immune system is a cause of significant morbidity in children, including infection, diabetes, and cancer. There is a great need to develop IS minimization/withdrawal and tolerance induction approaches.

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
Liver disease in children in the developing world is a frequent occurrence, which is generally inadequately managed because of lack of resources. However, increasingly, there has been a demand for liver transplantation, where primary medical or surgical therapies have failed. The expertise and infrastructure required for a successful outcome are no different from those in more developed countries; if anything, the challenges are greater. Lack of deceased donors because of cultural and religious factors has driven the use of living donors. Short-term survival has generally been good, but long-term outcomes have rarely been reported. In this article, we review the experience of 2 centers at opposite ends of the continent and share our experience of slightly different settings and show that success can be achieved even in resource-reduced environments.

Abstract
The long-term impact of pediatric liver transplantation (LT) and its complications on general health, health-related quality of life (HRQoL) and sexual health were assessed. We conducted a national cross-sectional study of all pediatric recipients who underwent LT between 1987 and 2007. Of 66 survivors, 57 participants (86%) were compared to randomly chosen healthy controls (n = 141) at 10.7 ± 6.6 years posttransplant. PedsQL4.0, SF-36, DISF-SR and AUDIT questionnaires for appropriate age groups were used. Patients and controls <7 years had similar HRQoL and 54% of patients aged over 7 scored within the controls' normal range on all HRQoL domains. In adult survivors, physical functioning and general health were decreased (p < 0.05). Biliary complications, reoperations and obesity were independently associated with reduced HRQoL (p < 0.05 for all). Still 64% of adult survivors considered their health excellent. Sexual health was similar to controls but LT recipients may experience problems with their orgasm strength (p = 0.050) and condom-based contraception was more common after LT than among controls (58% and 12%, p < 0.001). In conclusion, normal HRQoL and sexual health are achievable post-LT.

Abstract
BACKGROUND Liver transplantation is well established worldwide as an effective treatment for end-stage liver disease in children. Acceptance in India has been slow because of considerations of cost, infections, inability to support long-term care, and non-availability of expertise. AIM This study was designed to report our experience with pediatric liver transplantation. MATERIALS AND METHODS Twenty-eight children underwent liver transplantation. RESULTS Biliary atresia was the commonest indication (n = 15) followed by metabolic liver disease. Twenty-six children had living donor transplants, mothers being the donors in a majority of these. Common surgical complications included bile leaks (n = 3) and vascular problems (n = 6). Common medical complications included infections, acute rejection, and renal failure. Overall, patient survival was 71%, while that for the last 14 cases was 92%. All survivors are doing well, have caught up with physical and developmental milestones and are engaged in age appropriate activities. CONCLUSIONS The study demonstrates the feasibility of a successful pediatric liver transplant program in our country.

Abstract
Adherence to a medical regimen has been defined as the extent to which a patient's behavior coincides with clinical prescriptions. In liver transplant patients, adherence to immunosuppressive therapy and to medical indications in general is crucial for short- and long-term outcomes. Nonadherence to immunosuppression carries a risk of graft rejection and potential graft loss, whereas nonadherence to general medical indications (eg, avoiding alcohol intake and smoking after transplantation) may be associated with other complications such as de novo tumors and increasing health care costs. Among adult liver transplant patients, the rate of nonadherence to immunosuppressive drugs ranges from 15% to 40%, whereas the rate of nonadherence to clinical appointments ranges from 3% to 47%. The wide range of reported rates is due to different definitions of the term nonadherence and the variety of methods used to measure adherence in the medical literature. Nonadherence seems to be nearly 4 times higher in pediatric and adolescent patients versus adult transplant recipients. Several nonadherence risk factors, such as high medication costs, psychiatric disorders, the conviction that the medication is harmful, and side effects of immunosuppressive therapy, have been described among adult liver transplant patients. The risk factors for nonadherence in pediatric and adolescent liver transplant patients are psychological distress, the functional status of their families, and the impact of immunosuppressive side effects on their physical appearance. A single approach to promoting adherence to general medical prescriptions has been proved to be ineffectual, so a multidisciplinary strategy should be adopted to achieve significant improvements in this field. The aim of this review is to analyze the published literature on adherence in liver transplant patients with a particular focus on the reported prevalence and the identified risk factors. Patients have been split into 2 age groups (adults and children/adolescents) because the scale of the problem and the potential risk factors differ in the 2 groups.

Abstract
BACKGROUND This prospective study explores and compares the relationship between patients' self-rated health (SRH) after kidney transplantation (KT) at different follow-up periods and its medical and nonmedical predictors over time. METHODS Patients (n = 128) who completed a questionnaire (the SRH question of the SF-36 and the End-Stage Renal Disease Symptom Checklist - Transplantation Module) were enrolled. Clinical data were retrieved from medical files. The sample was stratified into early (n = 89) and late (n = 39) cohorts according to time since KT at baseline. Linear regression was used to identify predictors of SRH at follow-up. RESULTS In both cohorts, a change in glomerular filtration rate (GFR) over time remained a predictor of SRH; in the early cohort, age was an additional predictor; in the late cohort, a change in transplantation-associated psychological distress over time and the number of late acute rejection episodes during the observation period were additional predictors. CONCLUSIONS Improvement in GFR over time predicted better SRH at each period after KT. Decreased transplantation-associated psychological distress and fewer late acute rejection episodes seemed to predict better SRH at a later follow-up period. Despite these observations, higher SRH was associated with better clinical outcomes.

Abstract
Impaired kidney function is a well-recognized complication following liver transplantation (LT). Studies of this complication in children have been limited by small numbers and insensitive outcome measures. Our aim was to define the prevalence of, and identify risk factors for, post-LT kidney dysfunction in a multicenter pediatric cohort using measured glomerular filtration rate (mGFR). We conducted a cross-sectional study of 397 patients enrolled in the Studies in Pediatric Liver Transplantation (SPLIT) registry, using mGFR < 90 mL/min/1.73 m(2) as the primary outcome measure. Median age at LT was 2.2 years. Primary diagnoses were biliary atresia (44.6%), fulminant liver failure (9.8%), metabolic liver disease (16.4%), chronic cholestatic liver disease (13.1%), cryptogenic cirrhosis (4.3%) and other (11.8%). At a mean of 5.2 years post-LT, 17.6% of patients had a mGFR < 90 mL/min/1.73 m(2) . In univariate analysis, factors associated with this outcome were transplant center, age at LT, primary diagnosis, calculated GFR (cGFR) at LT and 12 months post-LT, primary immunosuppression, early post-LT kidney complications, age at mGFR, height and weight Z-scores at 12 months post-LT. In multivariate analysis, independent variables associated with a mGFR <90 mL/min/1.73 m(2) were primary immunosuppression, age at LT, cGFR at LT and height Z-score at 12 months post-LT.

Abstract
OBJECTIVE To evaluate patient survival and allograft function and health-related quality of life (HRQOL) 20 years after orthotopic liver transplantation (LT). SUMMARY OF BACKGROUND DATA Although LT is the established treatment of choice for acute and chronic liver failure, allograft function and recipient HRQOL 20 years after LT remain undefined. METHODS We performed a prospective, cross-sectional study of LT recipients surviving 20 years or more. Clinical data were reviewed to identify factors associated with 20-year survival. Survivors were directly contacted and offered a survey to assess HRQOL (SF-36; Liver Disease Quality of Life), social support, and cognition (Neuropsychological Impairment Scale). Logistic regression analysis was performed to identify clinical factors influencing HRQOL 20 years after LT. RESULTS Between February 1, 1984 and December 31, 1988, a total of 293 patients (179 adults, 114 children) received 348 LTs. Of the 293 patients, 168 (56%) survived for 20 years or more. Actuarial 20-year survival was 52% (patient) and 42% (graft). Factors associated with 20-year survival included recipient age <18 (P = 0.01), nonurgent LT (P = 0.01), no retransplantation (0.02), female gender (0.03), absence of biliary complications (P = 0.04), and short total ischemia time (P = 0.05). Rejection episodes were seen in a greater proportion of 20-year survivors than in nonsurvivors (35% vs. 27%; P = 0.3). Of the 168 survivors, 87 were contacted, and 68 (78%) completed the HRQOL surveys. Compared with the general population, survivors had lower physical scores (P < 0.01) but comparable mental scores on the SF-36. Overall HRQOL was significantly better in 20-year survivors than in patients with chronic liver disease, congestive heart failure, or diabetes. Clinical factors associated with improved post-LT HRQOL were younger age at LT, allograft longevity, and strong social support. More than 90% of pediatric survivors completed high school. After LT, 34% of pediatric recipients married, and 79% remained married at 20 years' follow-up. CONCLUSIONS More than 50% of LT recipients survive 20 years, achieve important socioeconomic milestones, and report quality of life superior to patients with liver disease or other chronic conditions. LT is a durable surgery that restores both long-term physiologic and psychologic well-being in patients with end-stage liver disease.

Abstract
The authors studied the psychosocial adjustment of pediatric liver transplant (LT) recipients reaching adulthood. The study comprised phone interviews of 116 volunteers aged 17-33 years. Results were compared to those for healthy peers and 65 patients who were eligible for inclusion but did not participate. Participants' median age at LT was 6 years and the median period since LT was 15 years. Of the 116 participants, 76% considered their quality of life as good or very good. Seventy-five patients (65%) were attending schools, 27 of whom were 2 years or more below the age-appropriate level. Of the remaining 41 patients, 26 had a job and 15 were unemployed. Poor compliance with medications was reported by 52 patients (45%). Alcohol consumption was lower than in the reference population (p < 0.001). Anxiety, loneliness and negative thoughts were expressed by 53, 84 and 47% of the participants, respectively. Thirteen patients (11%) were being cared for by psychologists or psychiatrists. The 65 nonparticipants had greater psychological problems than the participants, and a lower educational level. In conclusion, after LT in early life, most patients displayed psychological vulnerability during early adulthood. The educational level of patients was lower than that of theirs peers.

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
The aim of the study was to identify factors affecting health-related quality of life (HRQL) in adolescents after liver transplantation. HRQL was measured using the CHQ-CF87 in 55 adolescents, aged 12-18 years. Factors associated with HRQL included allograft morbidity, psychological and family-related variables measured through standardized questionnaires. The domains of the CHQ-CF87 were reduced using factor analysis to give physical, psychological and social domains. Impacting factors were identified through stepwise, multiple regression analysis. Adolescents had significantly lower HRQL in every domain except for role/social-behavior and family cohesion compared to the general population. Adolescents experienced median 18 (range 4-31) symptoms related to immunosuppression, 40(75%) had one or more chronic illnesses related to immunosuppression and 12(22%) had a history of emotional difficulties. Self-esteem and emotional health were similar to the general population but behavior and aspects of family function were lower. Following regression analysis, the factors associated with HRQL were: age at transplant, secondary chronic illness, symptom distress, headaches, history of emotional difficulties, self-esteem and family conflict. These explained 57% of the variance in physical function, 61% of psychological function and 39% of social function. HRQL is significantly reduced in adolescents after transplantation, which could be related to immunosuppression and psychosocial factors.

Abstract
PURPOSE OF REVIEW The aim is to review available data regarding the risks and benefits of indefinite immunosuppression against attempted immunosuppression withdrawal for children who have undergone liver transplantation. RECENT FINDINGS Emerging data suggest that conventional immunosuppression practices may well be responsible for a substantial proportion of the long-term mortality and morbidity burden borne by pediatric liver transplant recipients. The cumulative risk of chronic kidney disease, infection, malignancy, and cardiovascular risk factors such as hypertension, diabetes, and hyperlipidemia appear to threaten the health and well being of children more than that of acute or chronic allograft rejection. In parallel, single-center experiences have suggested that gradual immunosuppression withdrawal can be done safely with higher success rates in pediatric compared with adult liver transplant recipients. The coalescence of these two data streams has engendered substantial interest in systematic exploration of the safety and efficacy of immunosuppression withdrawal in conjunction with a vigorous scientific effort to elucidate an immunologic signature predictive of successful withdrawal. SUMMARY There is a concerted effort within the transplant community to identify biomarkers that can accurately predict the success of immunosuppression withdrawal after liver transplantation. Freedom from lifelong immunosuppression is likely to yield considerable benefit, particularly for children who face the longest lifetime horizons.

Abstract
OBJECTIVES Although liver transplantation has been the standard of care therapy for life-threatening liver diseases for >20 years, data on the long-term impact of liver transplantation in children have been primarily limited to single-center experiences. The objective of this study was to characterize and evaluate the clinical course of children who have survived >or=5 years after pediatric liver transplantation in multiple centers across North America. PATIENTS AND METHODS Patients enrolled in the Studies of Pediatric Liver Transplantation database registry who had undergone liver transplantation at 1 of 45 pediatric centers between 1996 and 2001 and survived >5 years from liver transplantation were identified and their clinical courses retrospectively reviewed. RESULTS The first graft survival for 461 five-year survivors was 88%, with 55 (12%) and 10 (2%) children undergoing a second and third liver transplantation. At the 5-year anniversary clinic visit, liver function was preserved in the majority with daily use of immunosuppression therapy, including a calcineurin inhibitor and oral prednisone, reported by 97% and 25% of children, respectively. The probability of an episode of acute cellular rejection occurring within 5 years after liver transplantation was 60%. Chronic rejection occurred in 5% patients. Posttransplant lymphoproliferative disease was diagnosed in 6% children. Calculated glomerular filtration rate was <90 mL/minute per 1.73 m2 in 13% of 5-year survivors. Age- and gender-adjusted BMI>95th percentile was noted in 12%, with height below the 10th percentile in 29%. CONCLUSIONS Children who are 5-year survivors of liver transplantation have good graft function, but chronic medical conditions and posttransplantation complications affect extrahepatic organs. A comprehensive approach to the management of these patients' multiple unique needs requires the expertise and commitment of health care providers both beyond and within transplant centers to further optimize long-term outcomes for pediatric liver transplant recipients.

Abstract
Hyperlipidemia is common in patients after LTX. Although immunosuppressive protocols have changed, there are only few data after pediatric LTX. Aim of our study was to evaluate short- and long-time effects of LTX on serum cholesterol and triglycerides in children with different immunosuppressive regimen. We retrospectively analyzed 24 children (seven boys) who underwent LTX since 1987 and were followed for at least one yr at the Medical University of Vienna. Serum lipids, liver function and records of immunosuppressive therapy were evaluated at first referral, shortly before and three, six, nine and 12 months after LTX, and at last visit (mean 6.6 yr after LTX). At first referral, serum lipids were significantly related to underlying disease and age. Following LTX, prevalence of hypercholesterolemia was 25% and of hypertriglyceridemia 90% after the first year. Long-term follow-up showed an overall decrease of serum lipids. Significant decreases in serum triglycerides were directly related to discontinuation of steroids. There was no effect of calcineurin inhibitors. Our study confirms the high prevalence of hyperlipidemia before and after pediatric LTX and suggests a major role of steroid-withdrawal for the control of post-transplant hypertriglyceridemia.

Abstract
Symptom experience (occurrence and perceived distress) associated with side effects of immunosuppressive medications in organ transplant patients may well be associated with poorer quality of life and medication non-compliance. The aims of this study were: first, to assess symptom experience in clinically stable adult patients during long-term follow-up after liver transplantation; and second, to study the relationship between symptom experience and medication non-compliance. This cross-sectional study included 123 liver transplant patients. Symptom experience was assessed using the "Modified Transplant Symptom Occurrence and Symptom Distress Scale" (29-item version) at the annual evaluation. According to the duration of follow-up, patients were divided into a short-term (1-4 yr) and a long-term (5-18 yr) cohort. Medication non-compliance was measured using electronic monitoring. Results showed that increased hair growth was the most frequent symptom in both sexes. Symptom distress was more serious in women than in men. The most distressing symptom in women was excessive and/or painful periods, while in men this was impotence. Clear differences were revealed at item level between symptom occurrence and symptom distress in relationship with the two time cohorts and between sexes. No relationship was found between symptom experience and prednisolone non-compliance.

Abstract
Lung transplant candidates and recipients are at high risk of infections from vaccine-preventable diseases. However, well-established guidelines neither exist for pre- and post-transplant vaccination nor do monitoring guidelines for pediatric lung transplant recipients. To ascertain the current vaccination and monitoring practices of pediatric lung transplant centers, a self-administered questionnaire was distributed to the 18 pediatric lung transplant centers within the International Pediatric Lung Transplant Collaborative in April 2006. Sixteen of 18 centers (89%) surveyed responded. Pretransplant, national vaccination guidelines are followed. Eleven centers reported following standardized vaccination guidelines post-transplant. Vaccines were more commonly provided by the primary-care physician pretransplant (69%) rather than post-transplant (38%). Post-transplant, 50% of the centers recommend live vaccines for household contacts but not for the transplant recipient. Pretransplant monitoring of response to prior vaccination was performed inconsistently except for varicella (88%). Only 44% of the transplant centers measure for response to vaccination post-transplant, mostly hepatitis B. Current vaccination practices of pediatric lung transplant centers are heterogeneous. The lung transplant community would be well served by studies designed to evaluate the efficacy of vaccinations in this population.

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
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 long-term histological outcome after pediatric liver transplantation (OLT) is not yet fully understood. De novo autoimmune hepatitis, consisting of histological chronic hepatitis associated with autoantibody formation and allograft dysfunction, is increasingly recognized as an important complication of liver transplantation, particularly in the pediatric population. In this study, 158 asymptomatic children with 5-year graft survival underwent protocol liver biopsies (113, 135, and 64 at 1, 5, and 10 years after OLT, respectively). Histological changes we re correlated with dinical,biochemical, and serological findings. All patients received cydosporine A as primary immunosuppression with withdrawal of corticosteroids at 3 months post OLT. Normal or near-normal histology was reported in 77 of 113 (68%), 61 of 135 (45%), and 20 of 64 (31%) at 1, 5, and 10 years, respectively. The commonest histological abnormality was chronic hepatitis (CH), the incidence of which increased with time [25/113 (22%), 58/135 (43%), and 41/64 (64%) at 1, 5, and 10 years, respectively) (P < .0001)]. The incidence of fibrosis associatedwith CH increasedwith time [13/25 (52%), 47/58 (81%), and 37/41 (91%) at 1, 5, and 10 years, respectively) (P < .0001)]. The severity of fibrosis associated with CH also increased with time, such that by 10 years 15% had progressed to cirrhosis. Aspartate aminotransfemse (AST) levels were slightly elevated in children with CH (median levels 52 IU/L, 63 IU/L, and 48 IU/L at 1, 5, and 10 years, respectively), but this did not reach statistical significance compared with those with normal histology. On multivariate analysis, the only factor predictive of chronic hepatitis was autoantibody positivity (present in 13% and 10% of children with normal biopsies at 5 and 10 years, respectively, and 72% and 80% of those with CH at 5 and 10 years, respectively) (P < .0001). Four children with CH and autoantibodies, who also had raised immunoglobulin G (IgG) levels and AST greater than 1.5 x normal fulfilled the diagnostic criteria for de novo autoimmune hepatitis (AIH). Another two were found to be hepatitis C positive. No definite cause for CH could be identified in the other cases. In condusion, chronic hepatitis is a common finding in children after liver transplantation and is associated with a high risk of developing progressive fibrosis, leading to cirrhosis. Standard liver biochemical tests cannot be relied on either in the diagnosis or in the monitoring of progress of chronic allograft hepatitis. In contrast, the presence ofautoantibodies is strongly associated with the presence of CH. The cause of chronic hepatitis in transplanted allografts is uncertain but may be immune mediated, representing a hepatitic form of chronic rejection.

Abstract
Effective immunosuppression has improved the results following liver transplantation, but also increased the risk for opportunistic infections. Epstein-Barr virus (EBV) infection in transplant patients can cause various symptoms including the life-threatening premalignant condition, post-transplantation lymphoproliferative disorder (PTLD). Serum specimens from 24 consecutive children (mean 7.6 specimens/patient), who had undergone liver transplantation in Göteborg from January 1995 to May 2002, were analyzed retrospectively for EBV DNA by real-time TaqMan polymerase chain reaction (PCR). The results were related to clinical picture, immunosuppression, graft rejection and infections with other agents. Eleven patients (46%) developed primary EBV infection at a mean time of 4.8 months after transplantation, and six (25%) reactivated EBV infection at a mean of 4.0 months after transplantation. Four of the 11 patients with primary infection had symptomatic EBV infection: two had PTLD and two hepatitis. One patient in the group with reactivated infection developed PTLD. EBV DNA levels were significantly higher in the group with primary symptomatic infection compared with the patients with primary asymptomatic infection (mean 65 500 copies/mL; range 14 200-194 300 vs. 3700 copies/mL; range 100-9780). In patients with symptomatic infection EBV DNA levels did not differ between PTLD and hepatitis patients. The data suggest that quantitative analysis of EBV DNA in serum by real-time PCR is useful for identification of EBV-related disease.

Abstract
PURPOSE The aim of this study was to study the late clinical features of biliary atresia in relation to pregnancy. MATERIALS AND METHODS Of the 175 patients with biliary atresia operated on at our department, the data for 49 patients (18 males, 31 females) older than 15 years were reviewed and analyzed. RESULTS Six patients delivered 7 newborns (5 with their native liver and 1 with a transplanted liver). Although one of the patients delivered twice after transplantation, another underwent transplantation after delivery. None of the 7 newborns showed any congenital anomalies; however, 6 were small-for-date newborns. Their birth weight tended to be inversely related to the mothers' age at delivery. An additional 13 patients required liver transplantation, of whom 1 died after transplantation and 1 died before transplantation. The remaining 30 patients showed uneventful courses without transplantation. The age at Kasai operation was significantly higher in the 5 patients who delivered babies with their native liver compared with that in these 30 patients (88.0 vs 68.6 days). A significant difference between these 5 patients and those who died or required transplantation before pregnancy was recognized even at the age of puberty in the alanine aminotransferase (36.5 +/- 26.5 vs 126.4 +/- 56.1 IU/L), aspartate aminotransferase (36.2 +/- 26.5 vs 114.2 +/- 48.9 IU/L), and choline esterase (249.7 +/- 64.8 vs 163.5 +/- 40.2 IU/L). CONCLUSIONS The age at Kasai operation may not necessarily impact the late clinical course; however, liver function at puberty may predict the subsequent clinical course, including the safety of pregnancy. The management strategies should be revised after puberty.

Abstract
Many children who receive solid-organ transplants have not completed their primary immunizations prior to transplantation. This leaves pediatric transplant recipients susceptible to the vaccine preventable illness of childhood, which if acquired post-transplantation are associated with increased rates of complications, hospitalization, graft rejection and mortality. The administration of vaccines to transplant candidates earlier and more rapidly than in the healthy child will improve vaccination rates among transplant recipients while not compromising immunogenicity. The recommended vaccines and vaccine schedule are discussed in detail.
