- Abstract
Background: The histological prevalence of allograft fibrosis in asymptomatic children after liver transplantation (LT) is well documented. However, long-term graft and patient survival remain unclear. This retrospective multicenter study aims to determine the prevalence of allograft fibrosis and analyze the long-term outcome for patients transplanted in childhood., Methods: We reviewed clinical data of children who had undergone 10-y protocol liver biopsies. We excluded patients with autoimmune hepatitis, primary sclerosing cholangitis, hepatitis B or C, and retransplantation. In total, 494 patients transplanted in childhood across 12 international transplant centers were included. We evaluated the development of fibrosis by comparing the results with biopsies obtained 5 and 15 y post-LT. Histological findings were correlated with graft and patient survival up to 20 y post-LT., Results: In the 10-y biopsies, periportal or pericentral fibrosis was observed in 253 patients (51%), 87 (18%) had bridging fibrosis, 30 (6%) had cirrhosis, and 124 (25%) had no fibrosis. The prevalence and stage of graft fibrosis significantly progressed from 5 to 10 y. At 10 y, the severity of fibrosis correlated significantly with inflammation. Patients with graft cirrhosis in the 10-y biopsy were more likely to die or require retransplantation subsequently ( P = 0.027)., Conclusions: At 10 y post-LT, most patients transplanted in childhood developed fibrosis, based on the protocol liver biopsies. Although mild-to-moderate graft fibrosis did not largely affect patient or graft survival up to 20 y post-LT, this progressive fibrosis finding has substantial implications for developing cirrhosis and portal hypertension in adult care., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2023 Wolters Kluwer Health, Inc.

- Abstract
Impaired renal function after pediatric (LT) is a recognized problem. Accurate monitoring of (GFR) is imperative to detect declining renal function. GFR can be estimated via s-creatinine and/or p-cystatin C or measured by inulin and or/iohexol clearances. We retrospectively compared eGFRcrea and eGFRcyst, to mGFRiohex after LT. Data from 91 children with 312 concomitant measurements of s-creatinine, p-cystatin C, and iohexol clearance, obtained between 2007 and 2015, were analyzed. eGFR was calculated by using the p-cystatin C-based CAPA and CKD-EPI formulas, and the s-creatinine-based Schwartz-LYON, FAS, revised Schwartz and MDRD formulas. Also, the arithmetic means of cystatin C-based and creatinine-based equations were used. Every calculated eGFR was compared to mGFRiohex in statistical correlation, accuracy, precision, bias, and misclassifications. Among the different equations, p-cystatin C-based formulas (CAPA and CKD-EPI) as well as the s-creatinine-based Schwartz-LYON formula showed the most correct estimates regarding accuracy (84-87.5%), bias (0.19-4.0 ml/min/1.73 m
2 ), and misclassification rate (24.7-25%). In patients with renal function <75 ml/min/1.73 m2 , cystatin C-based formulas were significantly more accurate and less biased than creatinine-based formulas. In conclusion, S-creatinine could be used in a clinical setting on a regular basis in liver transplanted pediatric patients, with reliable results, if eGFR is calculated by the Schwartz-LYON formula. When suspected renal dysfunction, cystatin C-based eGFR should be calculated, since it gives more accurate and less biased estimates than creatinine-based eGFR, and should be confirmed by mGFR (iohexol)., (© 2021 Wiley Periodicals LLC.)- Published

- Abstract
Cancer after liver transplantation (LT) constitutes a threat also for young recipients, but cancer risk factors are usually absent in children and large studies on the cancer risk profile in young LT recipients are scarce. Data of patients younger than 30 years who underwent LT during the period 1982-2013 in the Nordic countries were linked with respective national cancer registries to calculate standardized incidence ratios (SIRs). A total of 37 cancer cases were observed in 923 patients with 7846 person-years of follow-up. The SIR for all cancer types, compared with the matched general population, was 9.8 (12.4 for males and 7.8 for females). Cumulative incidence of cancer adjusted for the competing risk of death was 2% at 10 years, 6% at 20 years, and 22% at 25 years after LT. Non-Hodgkin lymphoma was the most common cancer type (n = 14) followed by colorectal (n = 4) and hepatocellular cancer (n = 4). Age was a significant risk factor for cancer, and the absolute risk of most cancers (except for lymphoma) increased considerably in young adults older than 20 years. The cancer risk pattern is different in pediatric and young LT patients compared with adult recipients. The striking increase in cancer incidence in young adulthood after the second decade of life deserves further consideration in transition programs., (© 2018 by the American Association for the Study of Liver Diseases.)

- Abstract
This study evaluates the transition from a local project to promote organ donation to a permanent county-based donation service inspired by the Spanish model. To address the problem of declining donation rates, a project with one donation-specialized nurse (DOSS) was initiated at a single neuro-intensive care unit. This project was later expanded into a permanent on-call service consisting of seven DOSSes, covering a large urban county. During the different periods (before, during project and during permanent service), the DOSS function's effect on donation rates was significant, and the number of eligible donors that became actual donors increased from 37% to 73% and 74%, respectively. The effect on family vetoes was as prominent with a decrease from 34% to 8% and 14%. The staff appreciation of the DOSS function was also evident during the periods; all areas included in the questionnaire (family care, donor care and staff support) have improved greatly owing to the DOSS. The transition from a single, local donation-nurse project, to an on-call service with several DOSSes covering a large urban county was a success considering the donation rates as well as the staff's appreciation. Hence, organizational models from abroad can be adjusted and successfully adopted., (© 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

- Abstract
Introduction: In Sweden, two donation campaigns have been carried out; one short term (STC) during October 2001, and one long term (LTC) between the years 2003-2005. The goal was not only to inform the public but also to create a positive attitude, make people talk about donation and formally declare their decision., Methods: The effects of the two campaigns were evaluated through three opinion polls., Results: The willingness to donate was widespread (86%) before and after the campaigns. The LTC increased the knowledge of the Donor Card (24-35%, p < 0.001) and the National Donor Registry (19-40%, p < 0.001). The LTC focused on making people register, still though, only a small increase of registrants was found (11-14%, p = 0.043). The proportion expecting the question of organ donation if their relative was to die under circumstances that made organ donation possible increased (73-79%, p = 0.002). No corresponding increase was found regarding the number having informed a relative about their decision (20-23%, ns)., Conclusion: The LTC was successful in increasing the expectation for the donation request. It also improved the knowledge of the Card and the Registry and slightly increased the number having registered. However, neither of the campaigns succeeded in making people inform their relatives.
