Living donation increases the organ supply, but associated non-medical expenses can disincentivize donation. Programs aimed at increasing living donation need to better understand how financial obstacles, including lost wages, impact the decision to pursue donation. Forty-eight interviews were conducted and analyzed using a grounded theory approach.

Our objective was to assess how financial barriers interact with motivators, other barriers, and facilitators during this process.
Methods: Data were obtained from a public survey assessing motivators, barriers, and facilitators of living donation.
Background: Minority race, ethnicity, and financial barriers are associated with lower rates of living donor (LD) kidney transplantation (LDKT). Financial reimbursement for LD costs may impact social determinants of health and, therefore, impact disparities in access to LDKT.
Methods: Among US LDKTs, we studied associations between racial and ethnic minority status and utilization of the National Living Donor Assistance Center (NLDAC), a means-tested reimbursement program for nonmedical LD costs.
Background: Sarcopenia occurs in pediatric chronic liver disease, although the prevalence and contributing factors in genetic intrahepatic cholestasis are not well-described. The objective of this study was to measure muscle mass in school-aged children with genetic intrahepatic cholestasis and assess relationships between sarcopenia, clinical variables, and outcomes.
Methods: Estimated skeletal muscle mass (eSMM) was calculated on dual-energy x-ray absorptiometry obtained in a Childhood Liver Disease Research Network study of children with bile acid synthesis disorders(BASD) alpha-1 antitrypsin deficiency (a1ATd), chronic intrahepatic cholestasis (CIC), and Alagille syndrome (ALGS).
Background And Aims: Detailed investigation of the biological pathways leading to hepatic fibrosis and identification of liver fibrosis biomarkers may facilitate early interventions for pediatric cholestasis.
Approach And Results: A targeted enzyme-linked immunosorbent assay-based panel of nine biomarkers (lysyl oxidase, tissue inhibitor matrix metalloproteinase (MMP) 1, connective tissue growth factor [CTGF], IL-8, endoglin, periostin, Mac-2-binding protein, MMP-3, and MMP-7) was examined in children with biliary atresia (BA; n = 187), alpha-1 antitrypsin deficiency (A1AT; n = 78), and Alagille syndrome (ALGS; n = 65) and correlated with liver stiffness (LSM) and biochemical measures of liver disease. Median age and LSM were 9 years and 9.
The conduct of long-term conventional randomized clinical trials in rare diseases is very difficult, making evidenced-based drug development problematic. As a result, real-world data/evidence are being used more frequently to assess new therapeutic approaches in orphan diseases. In this investigation, inclusion and exclusion criteria from a published trial of maralixibat in Alagille syndrome (ALGS, ITCH NCT02057692) were applied to a prospective longitudinal cohort of children with cholestasis (LOGIC NCT00571272) to derive contextual comparator data for evolving clinical trials of intestinal bile acid transport inhibitors in ALGS.

Methods: Analyses included participants with pathogenic biallelic mutations in adenosine triphosphate (ATP)-binding cassette subfamily B member 11 (ABCB11) (bile salt export pump; BSEP) or adenosine triphosphatase (ATPase) phospholipid transporting 8B1 (ATP8B1) (familial intrahepatic cholestasis; FIC1), or those with monoallelic or biallelic mutations in adenosine triphosphate (ATP)-binding cassette subfamily B member 4 (ABCB4) (multidrug resistance; MDR3), prospectively enrolled in the Longitudinal Study of Genetic Causes of Intrahepatic Cholestasis (LOGIC; NCT00571272) between November 2007 and December 2013. Summary statistics were calculated to describe baseline demographics, history, anthropometrics, laboratory values, and mutation data.
Alagille syndrome (ALGS) is an autosomal dominant multisystem disorder with cholestasis as a defining clinical feature. We sought to characterize hepatic outcomes in a molecularly defined cohort of children with ALGS-related cholestasis. Two hundred and ninety-three participants with ALGS with native liver were enrolled.

Methods: Using data from 6574 National Living Donor Assistance Center (NLDAC) participants (November 1, 2007-December 31, 2018), we utilized a cross-sectional study design to evaluate short-term depressive symptoms and satisfaction with life in living donors and non-donors (those who were declined or withdrew from evaluation) using the Satisfaction with Life Scale (SWLS) and the PHQ-8, with and without risk adjustment using linear regression.
Results: National Living Donor Assistance Center participants originated from 207 US transplant centers.
Living organ donors face direct costs when donating an organ, including transportation, lodging, meals, and lost wages. For those most in need, the National Living Donor Assistance Center (NLDAC) provides reimbursement to defray travel and subsistence costs associated with living donor evaluation, surgery, and follow-up. While this program currently supports 9% of all US living donors, there is tremendous variability in its utilization across US transplant centers, which may limit patient access to living donor transplantation.

In this collaborative study, we compared kidney graft outcomes among 4 countries (United States, United Kingdom, Australia, and New Zealand) on 3 continents. We analyzed transplant and follow-up registry data from 1988-2014 for 379 257 recipients of first kidney-only transplants using Cox regression.

If treatment is assigned after the start of follow-up, traditional methods (eg, adjustment for baseline-only covariates or fully conditional adjustment for time-dependent covariates) may give biased results. We propose a two-stage modeling approach using the method of sequential stratification to accurately estimate the effect of a time-dependent treatment on the recurrent event rate.

Using a novel data linkage between the Scientific Registry of Transplant Recipients and Centers for Medicare and Medicaid Services, our study has 2 objectives: (1) to determine risk factors for "early" hospitalization (ie, within 6 months of LT); and (2) to quantify the importance of hospitalization history in the first 6 months with respect to subsequent patient survival (ie, survival, conditional on surviving 6 months post-LT). The study population consisted of patients aged ≥18 years who underwent deceased donor LT between January 1, 2003 and December 31, 2010, with Medicare as primary or secondary insurance and were discharged alive from the index LT hospitalization (n = 7220).

Methods: Recipients of 274 living donor liver transplant were enrolled in the Adult-to-Adult Living Donor Liver Transplantation Cohort Study, including 233 (85.0%) right lobes, 40 (14.
Background: We examined the association of incident end-stage renal disease (ESRD) after liver transplantation (LT) and resource utilization using a data linkage between the Scientific Registry of Transplant Recipients and claims data from the Centers for Medicare and Medicaid Services.
Methods: The study cohort consisted of patients aged ≥18 years who underwent deceased donor LT between January 1, 2003, and December 31, 2010, with Medicare as primary or secondary insurance and were discharged alive from the index LT hospitalization (n = 7019). The association of ESRD and post-LT hospitalization was assessed by sequential stratification, which entailed prognostic score matching of ESRD-free patients to each LT recipient at ESRD onset.
Primary sclerosing cholangitis (PSC) recurs in 15%-25% of patients transplanted for PSC. In the United States, PSC transplant patients are more likely to receive an organ from a living donor (LD) than patients without PSC. Our aims were to (1) compare risk of PSC recurrence in LD versus deceased donor recipients and (2) identify risk factors for PSC recurrence.

Early allograft dysfunction definitions include a variable constellation of findings, including hyperbilirubinemia, coagulopathy, encephalopathy, and ascites formation. Among putative causes of EAD after LDLT are excessive portal pressure and/or flow.
