    Assessment of Psychoeducational Outcomes After Pediatric Liver Transplant

    AMERICAN JOURNAL OF TRANSPLANTATION, Issue 2 2009
    S. Gilmour
    Outcomes research in pediatric liver transplant (LT) has focused on mortality and morbidity but there is a need to also evaluate functional outcomes. Standardized cognitive testing was administered to a cohort of children with infantile chronic liver disease who were transplanted at the University of Alberta during their preschool years. Thirty children had comprehensive assessments with the Bayley Scales of Infant Development or Wechsler testing. Patient variables potentially associated with cognitive delay were analyzed with multiple regression analysis. The mean DQ/IQ score (developmental quotient/intelligence quotient) was 81 ± 17. Delay (DQ/IQ score < 70), and borderline delay (DQ/IQ 70,84) were each present in 27% of the cohort, with only 46% demonstrating normal cognition. Regression analysis demonstrated that the decreased IQ was associated with pretransplant growth retardation and elevated calcineurin inhibitor levels. Performance IQ had strong correlation with pretransplant growth retardation and elevated serum ammonia, R2= 45%, compared to verbal IQ that was associated was elevated calcineurin inhibitor levels, R2= 23%. Children post-LT are at high risk for cognitive delay or borderline delay. This is the first study to demonstrate the association calcineurin inhibitors with impaired IQ and also the unique finding of different variables predictive of impaired verbal intelligence quotient (VIQ) versus performance intelligence quotient (PIQ).

    Liver transplantation is accepted as the standard management for end-stage liver disease in children. Pediatric heart and heart-lung transplant recipients have shown significantly diminished exercise capacities compared with age-matched, able-bodied, control subjects. The primary aim of this study is to compare the fitness levels of a group of pediatric liver transplant (LT) recipients (LT group, 20 boys, 9 girls; age, 8.9 ± 4.8 years; 56 ± 35 months posttransplantation) with a group of able-bodied control subjects (22 boys, 12 girls; age, 8.4 ± 3.8 years). The secondary aim is to compare the performance of the LT group against the Fitnessgram criterion standards. We assessed muscular endurance by means of a partial curl-up, flexibility by means of the back-saver sit and reach, and cardiorespiratory fitness by means of the progressive aerobic cardiovascular endurance run (PACER). The only significant (P < .05) difference between the 2 groups was the number of shuttles run in the PACER (control, 16.8 ± 9.8 v LT, 11.5 ± 8.4 shuttles). Other differences between the 2 groups were not significant. With regard to satisfying the Fitnessgram criterion standards, only 35% of the LT group achieved the standards for the partial curl-up, 88% of the LT group achieved the criterion standards for flexibility, and 0% achieved the standards for the PACER. These results indicate that the LT group has diminished exercise capacity. The origins of exercise limitations deserve further investigation. [source]


    Towards minimizing immunosuppression in pediatric liver transplant recipients

    PEDIATRIC TRANSPLANTATION, Issue 5 2009

    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.

    Arterial-venous fistulas following pediatric liver transplant case studies

    PEDIATRIC TRANSPLANTATION, Issue 6 2007

    Abstract:, AV fistula is a rare but serious complication following pediatric liver transplant and may lead to graft loss. Our aim was to describe two pediatric centers' experience with the diagnosis, treatment and outcomes of children who presented with AV fistulas post-liver transplantation We report five cases of late arterio-portal fistula following liver transplantation. Four children were successfully treated with coil embolization. All of the children in this series had liver biopsies within 2,6 months of their AV fistula diagnosis. All biopsies were performed using a Bard Monopty 18 gauge needle with no ultrasound guidance and only one pass per biopsy. Two children also had PTC 4,8 months prior to their diagnosis of AV fistula. Three of the five children in this series had GI bleeds requiring banding or sclerotherapy. The other two had varices found on CT scan. All five cases in this series had ascites on their initial presentation. Four out of the five children had a history of non-compliance and the other child had a history of malabsorption and chronic diarrhea. [source]


    Current Lifestyle of Young Adults After Liver Transplantation During Childhood

    AMERICAN JOURNAL OF TRANSPLANTATION, Issue 7 2010
    J. P. Dommergues
    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. [source]

    Predictors of clinical outcome in children undergoing orthotopic liver transplantation for acute and chronic liver disease

    LIVER TRANSPLANTATION, Issue 9 2006

    The current United Network for Organ Sharing (UNOS) policy is to allocate liver grafts to pediatric patients with chronic liver disease based on the pediatric end-stage liver disease (PELD) scoring system, while children with fulminant hepatic failure may be urgently listed as Status 1a. The objective of this study was to identify pre-transplant variables that influence patient and graft survival in those children undergoing LTx (liver transplantion) for FHF (fulminant hepatic failure) compared to those patients transplanted for extrahepatic biliary atresia (EHBA), a chronic form of liver disease. The UNOS Liver Transplant Registry was examined for pediatric liver transplants performed for FHF and EHBA from 1987 to 2002. Variables that influenced patient and graft survival were assessed using univariate and multivariate analysis. Kaplan-Meier analysis of FHF and EHBA groups revealed that 5 year patient and graft survival were both significantly worse (P < 0.0001) in those patients who underwent transplantation for FHF. Multivariate analysis of 29 variables subsequently revealed distinct sets of factors that influenced patient and graft survival for both FHF and EHBA. These results confirm that separate prioritizing systems for LTx are needed for children with chronic liver disease and FHF; additionally, our findings illustrate that there are unique sets of variables which predict survival following LTx for these two groups.

    Fulminant hepatic failure: Wilson's disease or autoimmune hepatitis?

    PEDIATRIC TRANSPLANTATION, Issue 1 2005
    Implications for transplantation
    Abstract:, Fulminant hepatic failure (FHF) accounts for 10,15% of pediatric liver transplants in the USA annually. Because the onset of FHF may be the first presentation of Wilson's disease (WD) and autoimmune hepatitis (AIH) in previously asymptomatic adolescents, determination of the etiology of FHF is critical as treatment and prognosis differ between these two entities. Patients with AIH may be salvaged by medical treatment. On the contrary, liver transplantation is currently the only life saving therapeutic option available for patients with WD who present with fulminant liver failure. To establish the diagnosis of WD and AIH in the setting of FHF remains challenging for diagnosticians and decisions regarding liver transplantation may be necessary before a diagnosis is firmly established. We report a previously asymptomatic patient who presented with FHF and clinical and laboratory features suggestive of both WD and AIH and who underwent successful therapeutic liver transplantation before the diagnosis of WD could be confirmed.
