Donor-recipient race-ethnicity concordance and patient survival after liver transplantation.

INTRODUCTION: We assessed the association between patient survival after liver transplantation (LT) and donor-recipient race-ethnicity (R/E) concordance. METHODS: The Scientific Registry of Transplant Recipients (SRTR) was retrospectively analyzed using data collected between 2002 and 2019. Only adults without history of prior organ transplant and recipients of LT alone were included. The primary outcome was patient survival. Donors and recipients were categorized into five R/E groups: White/Caucasian, African American/Black, Hispanic/Latino, Asian, and Others. Statistical analyses were performed using Kaplan-Meier survival curves and Cox Proportional Hazards models, adjusting for donor and recipient covariates. RESULTS: 85,427 patients were included. Among all the R/E groups, Asian patients had the highest 5-year survival (81.3%; 95% CI = 79.9-82.7), while African American/Black patients had the lowest (71.4%; 95% CI = 70.3-72.6) (P < 0.001). Lower survival rates were observed in recipients who received discordant R/E grafts irrespective of their R/E group. The fully adjusted hazard ratio for death was statistically significant in African American/Black (aHR 1.07-1.18-1.31; P < 0.01) and in White∕Caucasian patients (aHR 1.00-1.04-1.07; P = 0.03) in the presence of donor-recipient R/E discordance. CONCLUSION: Disparities in post-LT outcomes might be influenced by biological factors in addition to well-known social determinants of health.

Severe Liver and Renal Injury From Tribulus Terrestris.

Tribulus terrestris is a shrub that is found worldwide. Although it has been linked to severe jaundice and death in grazing animals, there are only a few case reports of hepatotoxicity in humans. We describe a case of a 46-year-old man who took tribulus supplements daily for 2 months. He developed severe jaundice prompting hospital admission. His total bilirubin peaked at 48 mg/dL, with concomitant renal dysfunction (creatinine of 7.1). His liver biopsy showed features consistent with drug-induced liver injury. He was initiated on a trial of plasmapheresis and underwent 3 sessions with a subsequent decrease in bilirubin with each session. He had appropriate renal recovery and was discharged home and on follow-up, continues to do well with most recent bilirubin of 1.1 mg/dL.

Postpartum Treatment for Chronic Hepatitis C Virus Among People With Opioid Use Disorder: A Prospective Pilot Clinical Trial.

OBJECTIVE: The objective of this study was to evaluate the feasibility and acceptability of postpartum hepatitis C virus (HCV) treatment integrated within a substance use treatment program for pregnant and postpartum people with opioid use disorder (OUD). METHODS: We conducted a prospective pilot clinical trial of sofosbuvir/velpatasvir (SOF/VEL) treatment among postpartum people with OUD and HCV. Feasibility outcomes included rates of HCV treatment utilization and completion, medication adherence, and sustained virologic response 12 weeks after treatment completion (SVR12). Acceptability was measured through self-reported adverse effects and medication adherence. RESULTS: From January 2018 to August 2021, 164 pregnant people received care for OUD at the study site. Among those, 64 (39.0%) were HCV antibody positive and 45 (27.4%) had active HCV infection. Among 45 eligible patients, 32 (71.1%) enrolled and 21 (46.7%) initiated HCV treatment. Of 21 participants who initiated treatment, 16 (76.2%) completed the SOF/VEL treatment, and 11 (52.4%) completed the SVR12. All participants who completed treatment were cured. Common reasons for dropout during the HCV clinical care cascade were OUD treatment discontinuation, illicit substance use recurrence, and lost to follow-up. Participants reported high satisfaction with HCV treatment, including minimal adverse effects, and no HCV treatment concerns. CONCLUSIONS: Nearly half of pregnant people with HCV initiated postpartum treatment within an integrated care model of HCV treatment within a substance use treatment program. Postpartum SOF/VEL was efficacious, tolerable, and acceptable. Despite this, postpartum HCV treatment among people with OUD remains challenging, and many barriers remain.

Alcohol treatment discussions and clinical outcomes among patients with alcohol-related cirrhosis.

BACKGROUND: Alcohol cessation is the cornerstone of treatment for alcohol-related cirrhosis. This study evaluated associations between medical conversations about alcohol use disorder (AUD) treatment, AUD treatment engagement, and mortality. METHODS: This retrospective cohort study included all patients with ICD-10 diagnosis codes for cirrhosis and AUD who were engaged in hepatology care in a single healthcare system in 2015. Baseline demographic, medical, liver disease, and AUD treatment data were assessed. AUD treatment discussions and initiation, alcohol cessation, and subsequent 5-year mortality were collected. Multivariable models were used to assess the factors associated with subsequent AUD treatment and 5-year mortality. RESULTS: Among 436 patients with cirrhosis due to alcohol, 65 patients (15%) received AUD treatment at baseline, including 48 (11%) receiving behavioral therapy alone, 11 (2%) receiving pharmacotherapy alone, and 6 (1%) receiving both. Over the first year after a baseline hepatology visit, 37 patients engaged in AUD treatment, 51 were retained in treatment, and 14 stopped treatment. Thirty percent of patients had hepatology-documented AUD treatment recommendations and 26% had primary care-documented AUD treatment recommendations. Most hepatology (86%) and primary care (88%) recommendations discussed behavioral therapy alone. Among patients with ongoing alcohol use at baseline, AUD treatment one year later was significantly, independently associated with AUD treatment discussions with hepatology (adjusted odds ratio (aOR): 3.23, 95% confidence interval (CI): 1.58, 6.89) or primary care (aOR: 2.95; 95% CI: 1.44, 6.15) and negatively associated with having Medicaid insurance (aOR: 0.43, 95% CI: 0.18, 0.93). When treatment was discussed in both settings, high rates of treatment ensued (aOR: 10.72, 95% CI: 3.89, 33.52). Over a 5-year follow-up period, 152 (35%) patients died. Ongoing alcohol use, age, hepatic decompensation, and hepatocellular carcinoma were significantly associated with mortality in the final survival model. CONCLUSION: AUD treatment discussions were documented in less than half of hepatology and primary care encounters in patients with alcohol-related cirrhosis, though such discussions were significantly associated with receipt of AUD treatment.

Poor Outcomes of Patients With NAFLD and Moderate Renal Dysfunction or Short-Term Dialysis Receiving a Liver Transplant Alone.

The outcomes of patients with moderate renal impairment and the impact of liver disease etiology on renal function recovery after liver transplant alone (LTA) are largely unknown. We explored whether NAFLD patients with pre-LTA moderate renal dysfunction (GFR 25-45 ml/min/1.73 m2) may be more susceptible to develop post-LTA severe renal dysfunction (GFR<15 ml/min/1.73 m2) than ALD patients, as well as other overall outcomes. Using the UNOS/OPTN database, we selected patients undergoing liver transplant for NAFLD or ALD (2006-2016), 15,103 of whom received LTA. NAFLD patients with moderate renal dysfunction were more likely to develop subsequent GFR<15 ml/min/1.73 m2 than ALD patients (11.1% vs. 7.38%, p < 0.001). Patients on short-term dialysis pre-LTA (≤12 weeks) were more likely to develop severe renal dysfunction (31.7% vs. 18.1%), especially in NAFLD patients, and were more likely to receive a further kidney transplant (15.3% vs. 3.7%) and had lower survival (48.6% vs. 50.4%) after LTA (p < 0.001 for all). NAFLD was an independent risk factor for post-LTA severe renal dysfunction (HR = 1.2, p = 0.02). NAFLD patients with moderate renal dysfunction and those receiving short-term dialysis prior to LTA are at a higher risk of developing subsequent severe renal dysfunction. Underlying etiology of liver disease may play a role in predicting development and progression of renal failure in patients receiving LTA.

The closing survival gap after liver transplantation for hepatocellular carcinoma in the United States.

BACKGROUND: Socio-economic inequalities among different racial/ethnic groups have increased in many high-income countries. It is unclear, however, whether increasing socio-economic inequalities are associated with increasing differences in survival in liver transplant (LT) recipients. METHODS: Adults undergoing first time LT for hepatocellular carcinoma (HCC) between 2002 and 2017 recorded in the Scientific Registry of Transplant Recipients (SRTR) were included and grouped into three cohorts. Patient survival and graft survival stratified by race/ethnicity were compared among the cohorts using unadjusted and adjusted analyses. RESULTS: White/Caucasians comprised the largest group (n=9,006, 64.9%), followed by Hispanic/Latinos (n=2,018, 14.5%), Black/African Americans (n=1,379, 9.9%), Asians (n=1,265, 9.1%) and other ethnic/racial groups (n=188, 1.3%). Compared to Cohort I (2002-2007), the 5-year survival of Cohort III (2012-2017) increased by 18% for Black/African Americans, by 13% for Whites/Caucasians, by 10% for Hispanic/Latinos, by 9% for patients of other racial/ethnic groups and by 8% for Asians (All P values<0.05). Despite Black/African Americans experienced the highest survival improvement, their overall outcomes remained significantly lower than other ethnic∕racial groups (adjusted HR for death=1.20; 95%CI 1.05-1.36; P=0.005; adjusted HR for graft loss=1.21; 95%CI 1.08-1.37; P=0.002). CONCLUSION: The survival gap between Black/African Americans and other ethnic/racial groups undergoing LT for HCC has significantly decreased over time. However, Black/African Americans continue to have the lowest survival among all racial/ethnic groups.

Perspectives on Anti-Black Racism and Mitigation Strategies Among Faculty Experts at Academic Medical Centers.

Importance: Black faculty and trainees remain underrepresented in academic medicine because of systemic racism. Years of diversity and inclusion efforts have not succeeded in eliminating the unique challenges faced by Black faculty in academic medicine. Objectives: To elicit expert faculty perspectives on anti-Black racism in academic medicine based on lived and/or professional experience and to solicit recommendations for an intervention for faculty to dismantle anti-Black racism within academic medical centers. Design, Setting, and Participants: This qualitative study included semistructured interviews with experts in understanding and dismantling anti-Black racism within academic medical centers. Participants had expertise in anti-Black racism through their lived experience as a Black faculty member and/or professional experience in diversity, equity, and inclusion efforts. Participants were recruited from academic medical centers from around the United States. Interviews were conducted through an online meeting platform, audio recorded, transcribed verbatim, and subsequently coded following an inductive qualitative description approach. Interviews were completed between October 2020 and March 2021. Main Outcomes and Measures: Outcomes include the experiences of Black faculty and trainees in academic medicine and recommendations for developing an intervention to dismantle anti-Black racism within academic medicine. Results: A total of 16 participants completed this study; most identified as Black or African American (9 [56%]) and female (10 [63%]). Results were sorted into 2 content domains, with several themes within those domains: (1) barriers faced by Black faculty and trainees and potential solutions and (2) recommendations for an intervention directed at faculty to dismantle anti-Black racism in academic medicine. Barriers faced by Black faculty and trainees included lack of representation; challenges with the recruitment, retention, and promotion of Black faculty; and experiences of microaggressions and overt racism. Participants suggested that an intervention should have a comprehensive learning objective; be mandatory for all faculty, with the exception of Black faculty; draw from outside expertise; and receive allocation of resources and funding equal to other important training modules. Conclusions and Relevance: The findings of this study affirm prior work about the unique challenges faced by Black faculty and trainees in academic medicine because of interpersonal and institutional racism and build on this prior work by soliciting recommendations to guide intervention development. An intervention to dismantle anti-Black racism within academic medicine is urgently needed and will require leadership buy-in and financial commitments from institutions for effective development and implementation.

Using Intervention Mapping to Develop a Novel Pain Self-Management Intervention for People with Cirrhosis.

BACKGROUND: Chronic pain is common among patients with cirrhosis and is challenging to treat. While promising, pain self-management (PSM) interventions have not been tailored to this population's needs. AIMS: To design a PSM intervention for patients with cirrhosis. METHODS: Semi-structured interviews with 17 patients with cirrhosis, 12 hepatologists, and 6 administrators from two medical centers were conducted to inform a rigorous, structured intervention mapping (IM) process. Qualitative content analysis was guided by social cognitive theory (SCT) and the Consolidated Framework for Implementation Research (CFIR) and incorporated into intervention development. A planning group met regularly throughout the intervention, to reach consensus about how to use data and theory to develop the intervention through IM. RESULTS: Participants described barriers to PSM behaviors, including the absence of simple, evidence-based interventions for pain for patients with cirrhosis, inadequate provider knowledge, time, and training, and lack of champions, funding, and communication. Patients described high motivation to treat pain using behavioral methods including meditation, prayer, and exercise. The intervention was designed to address barriers to PSM behaviors for patients with cirrhosis, using behavior change methods that address knowledge, self-efficacy, and outcome expectations. The LEAP (Liver Education About Pain) intervention is a 12-week, modular intervention delivered by phone via individual and group sessions with a health coach. CONCLUSIONS: People with cirrhosis, hepatologists, and administrators informed this theory-driven, tailored PSM intervention, which was designed to be implementable in the real world.

Characteristics of opioid prescribing to outpatients with chronic liver diseases: A call for action.

BACKGROUND: Chronic liver disease (CLD) is among the strongest risk factors for adverse prescription opioid-related events. Yet, the current prevalence and factors associated with high-risk opioid prescribing in patients with chronic liver disease (CLD) remain unclear, making it challenging to address opioid safety in this population. Therefore, we aimed to characterize opioid prescribing patterns among patients with CLD. METHODS: This retrospective cohort study included patients with CLD identified at a single medical center and followed for one year from 10/1/2015-9/30/2016. Multivariable, multinomial regression was used identify the patient characteristics, including demographics, medical conditions, and liver-related factors, that were associated with opioid prescriptions and high-risk prescriptions (≥90mg morphine equivalents per day [MME/day] or co-prescribed with benzodiazepines). RESULTS: Nearly half (47%) of 12,425 patients with CLD were prescribed opioids over a one-year period, with 17% of these receiving high-risk prescriptions. The baseline factors significantly associated with high-risk opioid prescriptions included female gender (adjusted incident rate ratio, AIRR = 1.32, 95% CI = 1.14-1.53), Medicaid insurance (AIRR = 1.68, 95% CI = 1.36-2.06), cirrhosis (AIRR = 1.22, 95% CI = 1.04-1.43) and baseline chronic pain (AIRR = 3.40, 95% CI = 2.94-4.01), depression (AIRR = 1.93, 95% CI = 1.60-2.32), anxiety (AIRR = 1.84, 95% CI = 1.53-2.22), substance use disorder (AIRR = 2.16, 95% CI = 1.67-2.79), and Charlson comorbidity score (AIRR = 1.27, 95% CI = 1.22-1.32). Non-alcoholic fatty liver disease was associated with decreased high-risk opioid prescriptions (AIRR = 0.56, 95% CI = 0.47-0.66). CONCLUSION: Opioid medications continue to be prescribed to nearly half of patients with CLD, despite efforts to curtail opioid prescribing due to known adverse events in this population.

COVID-19 and the Uncovering of Health Care Disparities in the United States, United Kingdom and Canada: Call to Action.

The coronavirus disease 2019 (COVID-19) pandemic created a crisis that disproportionately affected populations already disadvantaged with respect to access to health care systems and adequate medical care and treatments. Understanding how and where health care disparities are most widespread is an important starting point for exploring opportunities to mitigate such disparities, especially within our patient population with liver disease. In a webinar in LiverLearning, we discussed the impact of the pandemic on the United States, United Kingdom and Canada, highlighting the disproportionate effects on infection rates and death for certain ethnic minorities, those socioeconomically disadvantaged and living in higher density areas, and those working in health care and other essential jobs. We set forth a "call to action" for members of the American Association for the Study of Liver Diseases and the larger community of providers of liver disease care to generate viable solutions to improve access to care and vaccination rates of our patients against COVID-19, and in general help reduce health care disparities and improve the health of disadvantaged populations within their communities. Solutions will likely involve personalized interventions and messaging for communities that honor local leaders and embrace the diverse needs and different cultural sensitivities of our unique patient populations.

Racial Diversity Among American Cardiologists: Implications for the Past, Present, and Future.

In the United States, race-based disparities in cardiovascular disease care have proven to be pervasive, deadly, and expensive. African American/Black, Hispanic/Latinx, and Native/Indigenous American individuals are at an increased risk of cardiovascular disease and are less likely to receive high-quality, evidence-based medical care as compared with their White American counterparts. Although the United States population is diverse, the cardiovascular workforce that provides its much-needed care lacks diversity. The available data show that care provided by physicians from racially diverse backgrounds is associated with better quality, both for minoritized patients and for majority patients. Not only is cardiovascular workforce diversity associated with improvements in health care quality, but racial diversity among academic teams and research scientists is linked with research quality. We outline documented barriers to achieving workforce diversity and suggest evidence-based strategies to overcome these barriers. Key strategies to enhance racial diversity in cardiology include improving recruitment and retention of racially diverse members of the cardiology workforce and focusing on cardiovascular health equity for patients. This review draws attention to academic institutions, but the implications should be considered relevant for nonacademic and community settings as well.

Expanding Donor Selection and Recipient Indications for Living Donor Liver Transplantation.

There is an acute shortage of deceased donor organs for liver transplantation in the United States. Nearly a third of patients either die or become too sick for transplant while on the transplant waitlist. Living donor liver transplantation (LDLT) bridges the gap between demand and supply of organs for liver transplantation. This article reviews current living donor selection criteria, and avenues for expansion of criteria with novel surgical techniques and ongoing outcomes research. Ways in which institutions can establish and expand LDLT programs using the Living Donor Champion model are discussed. Efforts to expand recipient indications for LDLT are described.

Preoperative Stratification of Liver Transplant Recipients: Validation of the LTRS.

BACKGROUND: The liver transplant risk score (LTRS) was developed to stratify 90-day mortality of patients referred for liver transplantation (LT). We aimed to validate the LTRS using a new cohort of patients. METHODS: The LTRS stratifies the risk of 90-day mortality of LT recipients based on their age, body mass index, diabetes, model for end-stage liver disease (MELD) score, and need for dialysis. We assessed the performance of the LTRS using a new cohort of patients transplanted in the United States between July 2013 and June 2017. Exclusion criteria were age <18 years, ABO incompatibility, redo or multivisceral transplants, partial grafts, malignancies other than hepatocellular carcinoma and fulminant hepatitis. RESULTS: We found a linear correlation between the number of points of the LTRS and 90-day mortality. Among 18 635 recipients, 90-day mortality was 2.7%, 3.8%, 5.2%, 4.8%, 6.7%, and 9.3% for recipients with 0, 1, 2, 3, 4, and ≥5 points (P < 0.001). The LTRS also stratified 1-year mortality that was 5.5%, 7.7%, 9.9%, 9.3%, 10.8%, and 15.4% for 0, 1, 2, 3, 4, and ≥5 points (P < 0.001). An inverse correlation was found between the LTRS and 4-year survival that was 82%, 79%, 78%, 82%, 78%, and 66% for patients with 0, 1, 2, 3, 4, and ≥5 points (P < 0.001). The LTRS remained an independent predictor after accounting for recipient sex, ethnicity, cause of liver disease, donor age, cold ischemia time, and waiting time. CONCLUSIONS: The LTRS can stratify the short- and long-term outcomes of LT recipients at the time of their evaluations irrespective of their gender, ethnicity, and primary cause of liver disease.

Prediction of Perioperative Mortality of Cadaveric Liver Transplant Recipients During Their Evaluations.

BACKGROUND: There are no instruments that can identify patients at an increased risk of poor outcomes after liver transplantation (LT) based only on their preoperative characteristics. The primary aim of this study was to develop such a scoring system. Secondary outcomes were to assess the discriminative performance of the predictive model for 90-day mortality, 1-year mortality, and 5-year patient survival. METHODS: The study population was represented by 30 458 adults who underwent LT in the United States between January 2002 and June 2013. Machine learning techniques identified recipient age, Model for End-Stage Liver Disease score, body mass index, diabetes, and dialysis before LT as the strongest predictors for 90-day postoperative mortality. A weighted scoring system (minimum of 0 to a maximum of 6 points) was subsequently developed. RESULTS: Recipients with 0, 1, 2, 3, 4, 5, and 6 points had an observed 90-day mortality of 6.0%, 8.7%, 10.4%, 11.9%, 15.7%, 16.0%, and 19.7%, respectively (P ≤ 0.001). One-year mortality was 9.8%, 13.4%, 15.8%, 17.2%, 23.0%, 25.2%, and 35.8% (P ≤ 0.001) and five-year survival was 78%, 73%, 72%, 71%, 65%, 59%, and 48%, respectively (P = 0.001). The mean 90-day mortality for the cohort was 9%. The area under the curve of the model was 0.952 for the discrimination of patients with 90-day mortality risk ≥10%. CONCLUSIONS: Short- and long-term outcomes of patients undergoing cadaveric LT can be predicted using a scoring system based on recipients' preoperative characteristics. This tool could assist clinicians and researchers in identifying patients at increased risks of postoperative death.

Atrial fibrillation in renal or liver transplant recipients: A systematic review and meta-analysis.

BACKGROUND: The prevalence of atrial fibrillation (AF) in patients undergoing renal (RT) or liver transplantation (LT) has increased during the last decades. Yet, there is still uncertainty on the association between AF and patient and graft survival. METHODS: Multiple electronic databases were searched using various combinations of keywords and MeSH terms pertinent to the exposure (AF), and outcomes (graft and patient survival). Randomized or quasi-randomized controlled studies, cohort and case-control studies on adults with documented AF undergoing RT or LT were included. The quality of studies was assessed using the Newcastle-Ottawa Assessment Scale. When appropriate, data on the primary and secondary outcomes were pooled in a meta-analysis using the random-effect model. The Odds ratio was used for patients undergoing LT and the hazard ratio was used for patients who underwent renal transplantation. RESULTS: A total of 50,362 publications were identified. Six studies, with a total of 136,331 patients, satisfied the inclusion criteria. LT was performed on 2861 patients and RT was performed on 133,470 recipients. Overall, AF affected 6652 (4.8%) transplant recipients. Among them, 153 received a LT and 6499 underwent RT. The OR for mortality after LT was 2.375 (95% CI; 1.532-3.682) (P = 0.000) in AF(+) recipients and the HR was 1.859 (95% CI; 1.031-3.354) (P = 0.039) after RT. The OR for graft loss in AF(+) after LT r was 1.088 (95% CI; 0.311-3.804) (P = 0.894) and the HR for graft loss was 1.632 (95% CI; 1.200-2.218) (P = 0.002) after RT. CONCLUSIONS: To the best of our knowledge, this is the first systematic review and meta-analysis to explore the association between AF and patient and graft survival after RT or LT. Our findings suggest that the presence of AF is associated with inferior patient survival. For renal transplant recipients, AF is also associated with inferior graft survival.
