Since the implementation of the Model of End-stage Liver Disease score-based allocation system, the number of transplant candidates with impaired renal function has increased. The aims of this review are to present new insights in the definitions and predisposing factors that result in acute kidney injury (AKI), and to propose guidelines for the prevention and treatment of postliver transplantation (LT) AKI. This review is based on both systematic review of relevant literature and expert opinion. Pretransplant AKI is associated with posttransplant morbidity, including prolonged post-LT AKI which then predisposes to posttransplant chronic kidney disease. Prevention of posttransplant AKI is essential in the improvement of long-term outcomes. Accurate assessment of baseline kidney function at evaluation is necessary, taking into account that serum creatinine overestimates glomerular filtration rate. New diagnostic criteria for AKI have been integrated with traditional approaches in patients with cirrhosis to potentially identify AKI earlier and improve outcomes. Delayed introduction or complete elimination of calcineurin inhibitors during the first weeks post-LT in patients with early posttransplant AKI may improve glomerular filtration rate in high risk patients but with higher rates of rejection and more adverse events. Biomarkers may in the future provide diagnostic information such as etiology of AKI, and prognostic information on renal recovery post-LT, and potentially impact the decision for simultaneous liver-kidney transplantation. Overall, more attention should be paid to pretransplant and early posttransplant AKI to reduce the burden of late chronic kidney disease.

Cirrhotic patients with RF, in particular with hepatorenal syndrome, CLKT is preferable to LTA because it improves liver allograft and patient survival.

IMPORTANCEThe burden of end-of-life care for patients with cirrhosis is increasing in the US, and most of these patients, many of whom are not candidates for liver transplant, die in institutions receiving aggressive care. Advance care planning (ACP) has been associated with improved end-of-life outcomes for patients with other chronic illnesses, but it has not been well-characterized in patients with decompensated cirrhosis. OBJECTIVE To describe the experience of ACP in patients with decompensated cirrhosis at liver transplant centers. DESIGN, SETTING, AND PARTICIPANTS For this multicenter qualitative study, face-to-face semistructured interviews were conducted between July 1, 2017, and May 30, 2018, with clinicians and patients with decompensated cirrhosis at 3 high-volume transplant centers in California. Patient participants were adults and had a diagnosis of cirrhosis, at least 1 portal hypertension-related complication, and current or previous Model for End-Stage Liver Disease with sodium score of 15 or higher. Clinician participants were health care professionals who provided care during the illness trajectory. MAIN OUTCOMES AND MEASURES Experiences with ACP reported by patients and clinicians. Participants were asked about the context, behaviors, thoughts, and decisions concerning elements of ACP, such as prognosis, health care preferences, values and goals, surrogate decision-making, and documentation. RESULTS The study included 42 patients (mean [SD] age, 58.2 [11.2] years; 28 men [67%]) and 46 clinicians (13 hepatologists [28%], 11 transplant coordinators [24%], 9 hepatobiliary surgeons [20%], 6 social workers [13%], 5 hepatology nurse practitioners [11%], and 2 critical care physicians [4%]). Five themes that represent the experiences of ACP were identified:(1) most patient consideration of values, goals, and preferences occurred outside outpatient visits; (2) optimistic attitudes from transplant teams hindered the discussions about dying;(3) clinicians primarily discussed death as a strategy for encouraging behavioral change; (4) transplant teams avoided discussing nonaggressive treatment options with patients; and (5) surrogate decision makers were unprepared for end-of-life decision-making.CONCLUSIONS AND RELEVANCE This study found that, despite a guarded prognosis, patients with decompensated cirrhosis had inadequate ACP throughout the trajectory of illness until the end of life. This finding may explain excessively aggressive life-sustaining treatment that patients receive at the end of life.

The appropriate interval between ligation sessions for treatment of esophageal variceal bleeding is uncertain. The optimal interval would provide variceal eradication as rapidly as possible to lessen early rebleeding while minimizing ligation-induced adverse events. We randomly assigned patients hospitalized with acute esophageal variceal bleeding who had successful ligation at presentation to repeat ligation at 1-week or 2-week intervals. Beta-blocker therapy was also prescribed. Ligation was performed at the assigned interval until varices were eradicated, and then at 3 and 9 months after eradication. The primary endpoint was the proportion of patients with variceal eradication at 4 weeks. Four-week variceal eradication occurred more often in the 1-week than 2-week group:37/45 (82%) vs. 23/45 (51%); difference = 31%, 95% CI 12 to 48%. Eradication occurred more rapidly in the 1-week group (18.1 vs. 30.8 days, difference = −12.7 days, 95%CI −20.0 to −5.4 days). The mean number of endoscopies to achieve eradication or to the last endoscopy in those not achieving eradication was comparable in the 1-week and 2-week groups (2.3 vs. 2.1), with the mean number of postponed ligation sessions 0.3 vs. 0.1 (difference = 0.2, 95% CI −0.02 to 0.4). Rebleeding at 4 weeks (4% vs. 4%) and 8 weeks (11% vs. 9%), dysphagia/odynophagia/chest pain (9% vs. 2%), strictures (0% vs. 0%), and mortality (7% vs.7%) were similar with 1-week and 2-week intervals. Conclusions One-week ligation intervals led to more rapid eradication than 2-week intervals without an increase in complications or number of endoscopies and without a reduction in rebleeding or other clinical outcomes. The decision regarding ligation intervals may be individualized based on physician and patient preferences and local logistics and resources.

Autoimmune hepatitis (AIH) is an inflammatory liver disease caused by environmental triggers in genetically predisposed patients. Development of acute AIH has been described in patients recently infected with viruses such as Epstein-Barr virus (EBV). 1 We describe a possible case of acute AIH in a patient recently infected with the novel coronavirus disease 2019 .A 54-year-old man with history of rheumatoid arthritis (RA) and scleritis presented with abdominal pain and jaundice. His RA and scleritis had been treated with infliximab (500 mg/kg every 8 weeks) for the past 10 years. He denied history of liver disease and consumption of alcohol, drugs including antibiotics or supplements.One month prior, the patient developed fevers and tested positive for COVID-19. He had spontaneous improvement in his symptoms. At the time of his COVID-19 diagnosis, serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels were elevated to 233 IU/L and 200 IU/L. Liver function tests (LFT) were previously normal. One month after his diagnosis, he presented with abdominal pain and pruritus. His laboratory tests showed elevated ALT to 1238 IU/L, AST to 1084 IU/L, total bilirubin to 25 mg/dL, alkaline phosphatase (ALP) to 251 IU/L and the international normalised ratio was 1.0.

Thrombocytopenia is one of the most common hematologic complications in cirrhosis. Despite limited data linking platelet count and bleeding risk in patients with cirrhosis, the use of platelets transfusions for invasive procedures has been a common practice. Recently, thrombopoietin (TPO) receptor agonists have been approved for use in patients with chronic liver disease (CLD) undergoing invasive procedures. The aim of this study was to review current literature on bleeding risk in patients with cirrhosis and the use of platelet transfusions and TPO receptor agonists in the context of invasive procedures. PubMed search was conducted to find articles relating to cirrhosis, thrombocytopenia, and new novel treatments for this condition. Search terms included CLD, cirrhosis, thrombocytopenia, bleeding, thrombosis, coagulopathy, hemostasis, and TPO receptor agonists. Romiplostim, eltrombopag, avatrombopag, and lusutrombopag are approved TPO receptor agonists, with avatrombopag and lusutrombopag specifically approved for use in patients with CLD undergoing invasive procedures. In patients with platelet counts < 50,000/mm3, avatrombopag and lusutrombopag increased the platelet counts above this threshold in the majority of treated patients and reduced the frequency of platelet transfusions. At the approved doses, incidence of thrombosis was not increased and therapies were well tolerated. Studies were not powered to assess whether risk of bleeding complications was reduced and the fundamental question of whether correction of thrombocytopenia is warranted in patients undergoing invasive procedures remains unanswered. The use of TPO receptor agonists has resulted in less requirement for platelet transfusions. In patients with cirrhosis undergoing invasive procedures for whom platelet transfusion is planned, TPO receptor agonists are an alternative and avoid the risks associated with transfusions. However, there is need for a thoughtful approach to manage bleeding risk in patients with cirrhosis undergoing procedures, with the consideration of a comprehensive hemostatic profile, the severity of portal hypertension, and the complexity of the invasive procedure to guide decisions regarding transfusions or use of TPO receptor agonists.

IntroductionAntiviral therapy for recurrent hepatitis C in liver transplant recipients has been associated with low efficacy, poor tolerability, and drug-drug interactions. Recent approval of various hepatitis C direct-acting antivirals has resulted in improvement of these parameters. We evaluated the efficacy and safety of 12 week all-oral interferon- and ribavirin-free therapy with sofosbuvir and simeprevir.MethodsThirty-two genotype 1 liver transplant recipients with recurrent hepatitis C infection were retrospectively analyzed. All patients received 12 weeks of sofosbuvir 400 mg and simeprevir 150 mg orally daily. The primary endpoint was sustained virologic response 12 weeks after treatment.ResultsSustained virologic response 12 weeks after treatment was achieved in 30 of 32 (94%; 95% confidence interval, 79-99%) patients. All patients enjoyed on-treatment virological response. Both patients who relapsed were cirrhotic, previously treated with Q80K polymorphism. Significant improvements in alkaline phosphatase, albumin, alanine aminotransferase levels, and platelets were seen at 12-week post therapy. Treatment was well tolerated. No grade 3 or 4 adverse events were noted. Headache and fatigue were the most common complaints.ConclusionCombination of sofosbuvir and simeprevir for 12 weeks resulted in 94% sustained virological response-12 rates in patients with hepatitis C genotype 1 and was well tolerated.

We report the findings of an early access program providing treatment for chronic hepatitis C virus infection (any genotype) with daclatasvir and sofosbuvir with/without ribavirin to patients with Child‐Pugh class C cirrhosis or prior liver transplant recipients with recurrent hepatitis C virus infection and advanced fibrosis/cirrhosis. Patients had <12‐month life expectancies per the local investigator. Patients received daclatasvir 60 mg and sofosbuvir 400 mg once daily, with/without ribavirin, for 24 weeks. Sustained virologic response (SVR) at posttreatment week 12 (SVR12) was measured. Assessments adhered to local standards. One patient (prior Child‐Pugh class C who improved to class B) enrolled by exemption was included in the overall data but not the class C cohort efficacy/safety data. Of the 77 treated patients, including 62 liver transplant recipients (genotype 1, n = 43, 69%; genotype 3, n = 16, 26%) and 14 patients with Child‐Pugh class C cirrhosis (genotype 1, n = 4, 29%; genotype 3, n = 10, 71%), 63 (82%) completed treatment. SVR12 rates by modified intention‐to‐treat analysis (excluding nonvirologic failures lost to follow‐up and withdrawal [consent/no reason]) in the overall, liver transplant, and Child‐Pugh class C cohorts were 84% (n = 64/76), 90% (n = 56/62), and 62% (n = 8/13), respectively. Rates increased to 96% (n = 64/67), 97% (n = 56/58), and 89% (n = 8/9), respectively, in patients with available virologic data (including early discontinuations); 22/23 patients with genotype 3 (96%) achieved SVR12. Single cases of virologic nonresponse and relapse (both in liver transplant recipients with genotype 1) and viral breakthrough (Child‐Pugh class C; genotype 3) occurred. Six patients died, 10 had adverse events leading to discontinuation, and 30 experienced serious adverse events. Conclusion: Daclatasvir plus sofosbuvir, with/without ribavirin, provided high SVR12 rates and was generally well tolerated in patients with life‐threatening disease and high unmet needs.
