RESUMO

Living donor kidney transplantation (LDKT) is one of the most effective treatment options for people with end-stage renal disease. Traditionally, LDKT can be either "directed" or "nondirected," based on whether the recipient is specified by the donor. Recently, there has been an increase in conditional and semidirected live kidney donation among strangers, where the donor specifies the characteristics of the recipient whom they wish to donate to. This practice has both gained popularity and sparked controversy in the state of Israel through the nonprofit organization Matnat Chaim. We analyze the ethical implications of this practice by applying traditional principles of medical ethics to conditional LDKT. Although semidirected and conditional LDKT presents some ethical challenges, overall, its practice effectively aligns with core ethical principles. The donors' right to make stipulations respects the donor's autonomy, the practice avoids harm and benefits both donor and recipient, and justice and utility are upheld as the practice specifically benefits marginalized patients and optimizes resource utilization. Finally, we present data from our institution demonstrating how conditional LDKT increased transplantation for all ethnic groups; Jewish recipients of LDKT increased by 151.32% (P = .034) Arab recipients of LDKT increased by 111.11% (P = .036).

RESUMO

Background: Severe acute alcoholic hepatitis (AAH) has an extremely poor prognosis with a high short term mortality rate. As a result, many centers, including our own, have allowed transplant patients to be listed for transplantation prior to achieving 6-months of sobriety. Several scoring systems, designed to target patients with a minimal period of sobriety, have been proposed to identify patients with alcohol use disorder (AUD), who would be predisposed to relapse after liver transplantation. We investigated whether these scoring systems corroborated the results of the non-structured selection criteria used by our center regarding decision to list for transplant. Methods: We conducted a retrospective case-control study of 11 patients who underwent early liver transplantation for AAH matched with 11 controls who were declined secondary to low insight into AUD. Blinded raters confirmed the severity of the diagnosis of DSM-5 and scored the patients on a variety of structured psychometric scales used to predict alcohol relapse. These included the High Risk for Alcohol Relapse Scale (HRAR), Stanford Integrated Psychosocial Assessment Tool (SIPAT), Alcohol Relapse Risk Assessment (ARRA), Hopkins Psychosocial Scale (HPSS), Michigan Alcoholism Prognosis Score (MAPS), Alcohol Use Disorders Identification Test -Consumption (AUDIT-C), and Sustained Alcohol Use Post-Liver Transplant (SALT) scales. All patients who underwent transplantation were followed for harmful and non-harmful drinking until the end of the study period. Results: The transplant recipients had significantly favorable MAPS, HRAR, SIPAT, ARRA, and HPSS scores with cutoffs that matched their previous research. The SALT and AUDIT-C scores were not predictive of our selection of patients for transplantation. Despite an expedited evaluation and no significant period of sobriety, our case cohort had a 30% relapse to harmful drinking after an average of 6.6 years (5-8.5 years) of follow-up. Discussion: Despite the rapid assessment and the short to no period of sobriety, the patient cohort demonstrated a 30% relapse to harmful drinking, consistent with the 20% to 30% relapse to drinking rate reported after liver transplantation for all forms of alcoholic liver disease. Average scores from MAPS, HRAR, SIPAT, ARRA, and HPSS corroborated our current stratification procedures, with lower mean risk scores found in the transplanted group. Conclusion: Patients with AUD and severe AAH who obtain new insight into their disease and posses other favorable psychosocial factors have low rates of AUD relapse post-liver-transplantation. The psychosocial selection criteria for patients with alcoholic hepatitis in our institution are consistent with 4 of the 5 scoring systems investigated in their prediction of sobriety post-transplant.

RESUMO

OBJECTIVE: Early liver transplantation (LT) is considered for patients with alcohol use disorder (AUD) despite limited sober time when acute mortality risk from liver disease is high. The objective of this paper is to find psychosocial tools that do not rely on extended sober time and predict alcohol relapse post-LT. METHODS: We conducted a systematic review of Pubmed, Embase, and Scopus for studies testing psychosocial tools that used numeric scoring to predict post-LT alcohol relapse. Tools that afforded points for length of sobriety were excluded. Each study was analyzed for its clinical context, post-LT relapse outcomes and predictive validity. RESULTS: Five scoring systems across fourteen samples showed varied validity in predicting post-LT alcohol relapse. Relapse to any alcohol use after LT revealed an average relapse rate of 23%. Most scoring systems were understudied but four of five provided cut-off scores with high negative predictive values for relapse. CONCLUSION: Scoring systems may have a place in candidate selection but the data on cut-off scores and predictability are still lacking for their use alone in high stakes LT selection. Larger studies with prospective scoring and standardized follow ups for relapse post-LT will better allow the predictive validity of these psychosocial tools to be compared.
