Terlipressin plus Albumin for the Treatment of Type 1 Hepatorenal Syndrome.

BACKGROUND: The vasoconstrictor terlipressin is used for type 1 hepatorenal syndrome (HRS-1) in many parts of the world and is part of the clinical practice guidelines in Europe. METHODS: We conducted a phase 3 trial to confirm the efficacy and safety of terlipressin plus albumin in adults with HRS-1. The patients were randomly assigned in a 2:1 ratio to receive terlipressin or placebo for up to 14 days; in both groups, concomitant use of albumin was strongly recommended. The primary end point was verified reversal of HRS, defined as two consecutive serum creatinine measurements of 1.5 mg per deciliter or less at least 2 hours apart and survival without renal-replacement therapy for at least 10 days after the completion of treatment. Four prespecified secondary end points were analyzed with the Hochberg procedure to account for multiple comparisons. RESULTS: A total of 300 patients underwent randomization - 199 were assigned to the terlipressin group and 101 to the placebo group. Verified reversal of HRS was reported in 63 patients (32%) in the terlipressin group and 17 patients (17%) in the placebo group (P = 0.006). With respect to the prespecified secondary end points, HRS reversal, defined as any serum creatinine level of 1.5 mg per deciliter or less during the first 14 days, was reported in 78 patients (39%) in the terlipressin group and 18 (18%) in the placebo group (P<0.001); HRS reversal without renal-replacement therapy by day 30, in 68 (34%) and 17 (17%), respectively (P = 0.001); HRS reversal among patients with systemic inflammatory response syndrome (84 patients in the terlipressin group and 48 patients in the placebo group), in 31 (37%) and 3 (6%), respectively (P<0.001); and verified reversal of HRS without recurrence by day 30, in 52 (26%) and 17 (17%), respectively (P = 0.08). At day 90, liver transplantations had been performed in 46 patients (23%) in the terlipressin group and 29 patients (29%) in the placebo group, and death occurred in 101 (51%) and 45 (45%), respectively. More adverse events, including abdominal pain, nausea, diarrhea, and respiratory failure, occurred with terlipressin than with placebo. Death within 90 days due to respiratory disorders occurred in 22 patients (11%) in the terlipressin group and 2 patients (2%) in the placebo group. CONCLUSIONS: In this trial involving adults with cirrhosis and HRS-1, terlipressin was more effective than placebo in improving renal function but was associated with serious adverse events, including respiratory failure.

Safety and efficacy of continuous terlipressin infusion in HRS-AKI in a transplant population.

Hepatorenal syndrome-acute kidney injury (HRS-AKI) is associated with significant morbidity and mortality. While liver transplantation is the definitive treatment, continuous terlipressin infusion for HRS-AKI may provide benefit and, as such, was assessed in a population composed of candidates for liver transplant (LT). Fifty hospitalized LT-eligible patients with HRS-AKI received a single bolus followed by continuous terlipressin infusion. Acute-on-chronic liver failure grade 3, serum creatinine (SCr)>5.0 mg/dL, or Model for End-Stage Liver Disease (MELD) ≥35 were exclusions. Fifty hospitalized patients who received midodrine and octreotide or norepinephrine for HRS-AKI served as a historical comparator cohort. Complete response (CR) was defined as a ≥30% decrease in SCr with end-of-treatment (EOT) SCr≤1.5, partial response as a ≥30% decrease in SCr with EOT SCr>1.5, and nonresponse as a <30% decrease in SCr. CR rate was significantly higher in the terlipressin cohort compared to the historical cohort (64% vs. 16%, p <0.001). Survival, while numerically higher in those who received terlipressin, was statistically similar (D30: 94% vs. 82%, p =0.12; D90: 78% vs. 68%, p =0.37). Renal replacement therapy (RRT) was more common among terlipressin NR than CR and PR (70% vs. 3% vs. 13%, p < 0.001). EOT MELD and SCr were significantly lower within terlipressin cohort (MELD: 19 vs. 25, SCr: 1.4 vs. 2.1 mg/dL, p <0.001). Sixteen of 40 terlipressin-treated patients received LT-alone (terlipressin CR in 10/16). One patient on terlipressin had a hypoxic respiratory failure that responded to diuretics; one possibly had drug-related rash. With continuous terlipressin infusion, a CR rate of 64% was observed with a favorable safety profile. Terlipressin use was associated with lower EOT MELD and SCr than the historical midodrine and octreotide/norepinephrine cohort; LT-alone was accomplished in a high proportion of complete terlipressin responders.

Après Moi, Le Deluge: The identification and management of flood syndrome in the emergency department.

Umbilical hernias develop in approximately 20% of patients with liver cirrhosis and ascites. Flood Syndrome is an eponym describing the spontaneous rupture of these umbilical hernias due to the elevated intrabdominal pressure associated with large-volume ascites. Though rare, Flood Syndrome is associated with several life-threatening sequela including infection, organ failure, and hypovolemic shock, leading to mortality or transplant in over 30% of patients. The following case is a single patient encounter describing an 80-year-old female with long-standing ascites who presented to the Emergency Department shortly after experiencing a spontaneous extravasation of fluid from her umbilical hernia.

Association of the COVID-19 pandemic with increased adherence among prevalent hemodialysis patients.

BACKGROUND: During the COVID-19 pandemic, there has been a reduction in emergency department visits and hospital admissions. We hypothesized that hemodialysis patients were decreasing their hospital visits and increasing their dialysis adherence during the COVID-19 pandemic. MATERIAL AND METHODS: This is a retrospective analysis of hemodialysis patients treated in the seven American Renal Associates (ARA) dialysis centers in the Dallas-Fort Worth metropolitan area. We conducted a "before-and-after" study using existing clinical data to examine patient adherence with hemodialysis between January 1 and March 14, 2020 (pre-COVID) and March 15 to May 18, 2020 (COVID) time periods. Data points included missed treatments, shortened treatments, post-dialysis weight, and hospital visits. Finally, we conducted an anonymous survey in which patients reported their hemodialysis adherence. RESULTS: Data analysis was performed on 556 patients. Significantly fewer patients missed a single treatment in the COVID vs. pre-COVID time periods (44.1 vs. 58.6%; p < 0.001). Significantly fewer patients finished their treatment with a post-dialysis weight more than 1 kg above their estimated dry weight in the COVID vs. pre-COVID time periods (31.7 vs. 38.9%, p = 0.01). Finally, there was a reduction in total hospital visits during the COVID vs. pre-COVID periods (12.6 vs. 19.4%; p = 0.002). The anonymous survey showed patients reporting increased adherence with hemodialysis and restriction of salt and water intake. CONCLUSION: The COVID time period was associated with increased adherence with hemodialysis and decreased hospital visits, and patients were conscious of these changes.

Estimating Glomerular Filtration Rate in Cirrhosis Using Creatinine-Based and Cystatin C-Based Equations: Systematic Review and Meta-Analysis.

Accurate estimation of kidney function in cirrhosis is crucial for prognosis and decisions regarding dual-organ transplantation. We performed a systematic review/meta-analysis to assess the performance of creatinine-based and cystatin C (CysC)-based eGFR equations compared with measured GFR (mGFR) in patients with cirrhosis. A total of 25 studies (n = 4565, 52.0 years, 37.0% women) comprising 18 equations met the inclusion criteria. In all GFR equations, the creatinine-based equations overestimated GFR (standardized mean difference, SMD, 0.51; 95% confidence interval [CI], 0.31-0.71) and CysC-based equations underestimated GFR (SMD, -0.3; 95% CI, -0.60 to -0.02). Equations based on both creatinine and CysC were the least biased (SMD, -0.14; 95% CI, -0.46 to 0.18). Chronic kidney disease-Epi-serum creatinine-CysC (CESC) was the least biased but had low precision and underestimated GFR by -3.6 mL/minute/1.73 m2 (95% CI, -17.4 to 10.3). All equations significantly overestimated GFR (+21.7 mL/minute/1.73 m2 ; 95% CI, 17.7-25.7) at GFR <60 mL/minute/1.73 m2 ; of these, chronic kidney disease-Epi-CysC (10.3 mL/minute/1.73 m2 ; 95% CI, 2.1-18.4) and GFR Assessment in Liver Disease (12.6 mL/minute/1.73 m2 ; 95% CI, 7.2-18.0) were the least biased followed by Royal Free Hospital (15 mL/minute/1.73 m2 ; 95% CI, 5.5-24.6) and Modification of Diet in Renal Disease 6 (15.7 mL/minute/1.73 m2 ; 95% CI, 10.6-20.8); however, there was an overlap in the precision of estimates, and the studies were limited. In ascites, overestimation of GFR was common (+8.3 mL/minute/1.73 m2 ; 95% CI, -3.1 to 19.7). However, overestimation of GFR by 10 to 20 mL/minute/1.73m2 is common in patients with cirrhosis with most equations in ascites and/or kidney dysfunction. A tailored approach is required especially for decisions regarding dual-organ transplantation.

A Model for Glomerular Filtration Rate Assessment in Liver Disease (GRAIL) in the Presence of Renal Dysfunction.

Estimation of glomerular filtration rate (eGFR) in patients with liver disease is suboptimal in the presence of renal dysfunction. We developed a model for GFR assessment in liver disease (GRAIL) before and after liver transplantation (LT). GRAIL was derived using objective variables (creatinine, blood urea nitrogen, age, gender, race, and albumin) to estimate GFR based on timing of measurement relative to LT and degree of renal dysfunction (www.bswh.md/grail). The measured GFR (mGFR) by iothalamate clearance (n = 12,122, 1985-2015) at protocol time points before/after LT was used as reference. GRAIL was compared with the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) and Modification of Diet in Renal Disease (MDRD-4, MDRD-6) equations for mGFR < 30 mL/min/1.73 m2 . Prediction of development of chronic kidney disease (mGFR < 20 mL/min/1.73 m2 , initiation of chronic dialysis) and listing or receipt of kidney transplantation within 5 years was examined in internal cohort (n = 785) and external validation (n = 68,217, 2001-2015). GRAIL had less bias and was more accurate and precise as compared with CKD-EPI, MDRD-4, and MDRD-6 at time points before/after LT for low GFR. For mGFR < 30 mL/min/1.73 m2 , the median difference (eGFR-mGFR) was GRAIL: 5.24 (9.65) mL/min/1.73 m2 as compared with CKD-EPI: 8.70 (18.24) mL/min/1.73 m2 , MDRD-4: 8.82 (17.38) mL/min/1.73 m2 , and MDRD-6: 6.53 (14.42) mL/min/1.73 m2 . Before LT, GRAIL correctly classified 75% as having mGFR < 30 mL/min/1.73 m2 versus 36.1% (CKD-EPI), 36.1% (MDRD-4), and 52.8% (MDRD-6) (P < 0.01). An eGFR < 30 mL/min/1.73 m2 by GRAIL predicted development of CKD (26.9% versus 4.6% CKD-EPI, 5.9% MDRD-4, and 10.5% MDRD-6) in center data and needing kidney after LT (48.3% versus 22.0% CKD-EPI versus 23.1% MDRD-4 versus 48.3% MDRD-6, P < 0.01) in national data within 5 years after LT. Conclusion: GRAIL may serve as an alternative model to estimate GFR among patients with liver disease before and after LT at low GFR.

Disparate Trends in Mortality of Etiology-Specific Chronic Liver Diseases Among Hispanic Subpopulations.

BACKGROUND & AIMS: Little is known about trends in mortality among Hispanic subpopulations and etiologies of chronic liver disease (CLD). We investigated trends in mortality of CLD among the 3 largest Hispanic subgroups based on origin (Mexicans, Puerto Ricans, and Cubans) in the United States (US) from 2007 to 2016. METHODS: We collected data from the US Census and national mortality database, calculated age-standardized mortalities for CLD among Hispanic subgroups, and compared these with non-Hispanic whites. We determined mortality rate patterns by joinpoint analysis with estimates of annual percentage change. RESULTS: Hispanics were relatively younger with a lower likelihood of high school education than non-Hispanic whites at time of death. Puerto Ricans had the highest rates of age-standardized hepatitis C virus-related mortality in 2016, followed by non-Hispanic whites, Mexicans, and Cubans. Age-standardized mortality rates associated with hepatitis B virus infection decreased steadily among all subjects. Age-standardized mortality rates from alcoholic liver disease and nonalcoholic fatty liver disease among non-Hispanic whites and all Hispanics increased and accelerated. Mexicans had the highest rates of age-standardized alcoholic liver disease-related mortality, followed by non-Hispanic whites, Puerto Ricans, and Cubans. Cirrhosis- and hepatocellular carcinoma-related mortality rates increased steadily from 2007 to 2016, with the highest among Puerto Ricans and non-Hispanic whites and Mexicans, and lowest in Cubans. CONCLUSIONS: We found high levels of heterogeneity in CLD-related mortality patterns among the 3 largest Hispanic subgroups. Therefore, combining Hispanics as an aggregate group obscures potentially meaningful heterogeneity in etiology-specific CLD-related mortality rates among Hispanic subgroups.

Antibiotic Prophylaxis for Spontaneous Bacterial Peritonitis: Benefit or Risk?

Spontaneous bacterial peritonitis (SBP) is associated with risk of acute on chronic liver failure (ACLF). Current guidelines recommend primary and secondary antibiotic prophylaxis for patients with cirrhosis and ascites who are at risk of a first episode and to prevent recurrence, respectively. Factors associated with prophylaxis failure leading to SBP, ACLF, and increased mortality are not well established. Gram-positive and multidrug-resistant organisms have become more frequently associated with SBP, particularly in the setting of ACLF. Efforts to understand how long-term antibiotic therapy may affect individual risk of SBP in this population will be critical to developing optimal preventive strategies.

The rise of the opioid epidemic and hepatitis C-positive organs: A new era in liver transplantation.

The use of hepatitis C virus (HCV)-positive organs in liver transplantation (LT) has increased in the era of direct-acting antiviral therapy. A rising demand for organs, the increased ability to effectively treat HCV infection in the transplant setting, and an unprecedented increase in HCV-positive donors have all contributed to this trend. A recent abrupt rise in opioid use in the United States has resulted in a surge of injection drug use, transmission of HCV, and opioid-related overdose deaths. Geographical areas most affected by the opioid epidemic have experienced a rapid increase in recovery and utilization of HCV-positive donor organs, in which the proportion of deceased donor LTs in the United States from donors who are HCV positive has increased nearly 2-fold within the last 3 years. The prospect of expanding the organ donor pool with HCV-positive donors and achieving acceptable posttransplant outcomes has generated much interest in the areas of liver, kidney, and thoracic transplantation, including the potential for transplanting organs from HCV positive donors into HCV-negative recipients. Developing strategies to ensure appropriate selection of potential recipients of HCV-positive organs, initiating timely antiviral therapy, and defining associated risks will be critical in achieving optimal posttransplant outcomes in this setting.

Increased Waitlist Mortality and Lower Rate for Liver Transplantation in Hispanic Patients With Primary Biliary Cholangitis.

BACKGROUND & AIMS: Data on the differences in ethnicity and race among patients with primary biliary cholangitis (PBC) awaiting liver transplantation (LT) are limited. We evaluated liver transplant waitlist trends and outcomes based on ethnicity and race in patients with PBC in the United States. METHODS: Using the United Network for Organ Sharing (UNOS) registry, we collected data on patients with PBC on the liver transplant waitlist, and performed analysis with a focus on ethnicity and race-based variations clinical manifestations, waitlist mortality and LT rates from 2000 to 2014. Outcomes were adjusted for demographics, complications of portal hypertension, and Model for End-stage Liver Disease score at time of waitlist registration. RESULTS: Although the number of white PBC waitlist registrants and additions decreased from 2000 to 2014, there were no significant changes in the number of Hispanic PBC waitlist registrants and additions each year. The proportion of Hispanic patients with PBC on the liver transplant waitlist increased from 10.7% in 2000 to 19.3% in 2014. Hispanics had the highest percentage of waitlist deaths (20.8%) of any ethnicity or race evaluated. After adjusting for demographic and clinical characteristics, Hispanic patients with PBC had the lowest overall rate for undergoing LT (adjusted hazard ratio, 0.71; 95% CI, 0. 60-0.83; P < .001) and a significantly higher risk of death while on the waitlist, compared to whites (adjusted hazard ratio, 1.41; 95% CI, 1.15-1.74; P < .001). Furthermore, Hispanic patients with PBC had the highest proportion of waitlist removals due to clinical deterioration. CONCLUSIONS: In an analysis of data from UNOS registry focusing on outcomes, we observed differences in rates of LT and liver transplant waitlist mortality of Hispanic patients compared with white patients with PBC. Further studies are needed to improve our understanding of ethnicity and race-based differences in progression of PBC.

Treatment of patients waitlisted for liver transplant with all-oral direct-acting antivirals is a cost-effective treatment strategy in the United States.

All-oral direct acting antivirals (DAAs) have been shown to have high safety and efficacy in treating patients with hepatitis C virus (HCV) awaiting liver transplant (LT). However, there is limited empirical evidence comparing the health and economic outcomes associated with treating patients pre-LT versus post-LT. The objective of this study was to analyze the cost-effectiveness of pre-LT versus post-LT treatment with an all-oral DAA regimen among HCV patients with hepatocellular carcinoma (HCC) or decompensated cirrhosis (DCC). We constructed decision-analytic Markov models of the natural disease progression of HCV in HCC patients and DCC patients waitlisted for LT. The model followed hypothetical cohorts of 1,000 patients with a mean age of 50 over a 30-year time horizon from a third-party US payer perspective and estimated their health and cost outcomes based on pre-LT versus post-LT treatment with an all-oral DAA regimen. Transition probabilities and utilities were based on the literature and hepatologist consensus. Sustained virological response rates were sourced from ASTRAL-4, SOLAR-1, and SOLAR-2. Costs were sourced from RedBook, Medicare fee schedules, and published literature. In the HCC analysis, the pre-LT treatment strategy resulted in 11.48 per-patient quality-adjusted life years and $365,948 per patient lifetime costs versus 10.39 and $283,696, respectively, in the post-LT arm. In the DCC analysis, the pre-LT treatment strategy resulted in 9.27 per-patient quality-adjusted life years and $304,800 per patient lifetime costs versus 8.7 and $283,789, respectively, in the post-LT arm. As such, the pre-LT treatment strategy was found to be the most cost-effective in both populations with an incremental cost-effectiveness ratio of $74,255 (HCC) and $36,583 (DCC). Sensitivity and scenario analyses showed that results were most sensitive to the utility of patients post-LT, treatment sustained virological response rates, LT costs, and baseline Model for End-Stage Liver Disease score (DCC analysis only). CONCLUSION: The timing of initiation of antiviral treatment for HCV patients with HCC or DCC relative to LT is an important area of clinical and policy research; our results indicate that pre-LT treatment with a highly effective, all-oral DAA regimen provides the best health outcomes and is the most cost-effective strategy for the treatment of HCV patients with HCC or DCC waitlisted for LT.

Medical and Behavioral Approaches to Engage People Who Inject Drugs Into Care for Hepatitis C Virus Infection.

Direct-acting antivirals for hepatitis C virus infection may revolutionize treatment among persons with substance use disorders. Despite persons with substance use disorders having the highest hepatitis C virus prevalence and incidence, the vast majority have not engaged into care for the infection. Previously, interferon-based treatments, with substantial side effects and the propensity to exacerbate mental health conditions, were major disincentives to pursuit of care for the infection. Direct-acting antivirals with viral eradication rates of >90%, significantly improved side effect profiles, and shorter treatment duration are dramatic improvements over prior treatment regimens that should promote widespread hepatitis C virus care among persons with substance use disorders. The major unmet need is strategies to promote persons with substance use disorders engagement into care for hepatitis C virus. Although physical integration of treatment for substance use and co-occurring conditions has been widely advocated, it has been difficult to achieve. Telemedicine offers an opportunity for virtual integration of behavioral and medical treatments that could be supplemented by conventional interventions such as hepatitis C virus education, case management, and peer navigation. Furthermore, harm reduction and strategies to reduce viral transmission are important to cease reinfection among persons with substance use disorders. Widespread prescription of therapy for hepatitis C virus infection to substance users will be required to achieve the ultimate goal of global virus elimination. Combinations of medical and behavioral interventions should be used to promote persons with substance use disorders engagement into and adherence with direct-acting antiviral-based treatment approaches. Ultimately, either physical or virtual colocation of hepatitis C virus and substance use treatment has the potential to improve adherence and consequently treatment efficacy.

Hepatitis B Virus Reactivation in the Setting of Cancer Chemotherapy and Other Immunosuppressive Drug Therapy.

Hepatitis B virus reactivation (HBVr) is an important complication of immunosuppressive drug therapy (ISDT). It can occur with active or resolved hepatitis B virus (HBV) infection with a clinical spectrum that ranges from mild elevations in liver tests to fulminant hepatic failure. The risk of it occurring is determined by the interplay between HBV serological status, level of viremia, and the immunosuppressive potency of the drug(s) used. Reactivation is most common during treatment of hematologic malignancies but also occurs with chemotherapy for breast cancer and numerous other solid organ malignancies, organ transplant, and immune suppression for nonmalignant conditions. The expansion of new biologic treatments for malignant and nonmalignant disorders has enlarged the population at risk. Increased awareness of HBVr among healthcare providers who prescribe ISDT, adoption of routine HBV screening, and linking the results of screening to antiviral prophylaxis are needed to reduce the incidence of this potentially fatal but preventable disorder.

Routine ultrasonography surveillance of native kidneys for renal cell carcinoma in kidney transplant candidates.

Renal cell carcinoma (RCC) has a high incidence in the kidney transplant population and annual surveillance detects these tumors early in their natural history. Minimal guidelines exist regarding RCC surveillance in ESRD patients awaiting transplant. A retrospective review of our kidney transplant database examined the outcomes of annual ultrasonographic surveillance during initial kidney transplant evaluation and upon annual reassessment. Of 2642 patients listed for transplant, 145 patients were found to have masses during initial kidney transplant evaluation or annual imaging consistent with new complex cystic disease or RCC. A total of 71 patients had RCC identified, with 52 found on initial kidney transplant evaluation and 19 identified on annual surveillance. Male gender and African-American race were independently associated with RCC (P<.05). RCC was detected a median of 2.0 years after listing (two annual ultrasonography studies). Patients with complex cysts were more likely to undergo transplantation (48.7%) compared to patients with RCC (21.1%; P<.001). There was no significant difference in survival between RCC patients and those found to have complex cystic disease, suggesting incidental RCC can be diagnosed early in the natural history and at a curable stage through implementation of a biennial surveillance program.

Incidental Finding of a Duodenal-Type Follicular Lymphoma in Metabolic Dysfunction-Associated Steatohepatitis Cirrhosis: A Rare Malignancy With Favorable Outcomes.

Duodenal-type follicular lymphoma (DFL) are uncommon, presenting in both symptomatic and asymptomatic patients, and are generally associated with a benign clinical course. Treatment options include surgery, radiation, and chemotherapy. However, many patients can be managed conservatively with little to no treatment, as 5-year progression-free survival is greater than 70%, and 5-year overall survival ranges from 80% to 94%. Here, we present a case of incidental DFL in a patient with metabolic dysfunction-associated steatohepatitis and cirrhosis. A review of the endoscopic and histologic characteristics, as well as epidemiology, risk factors, and long-term outcomes, may guide management strategies when DFL is encountered.

Terlipressin vs Midodrine Plus Octreotide for Hepatorenal Syndrome-Acute Kidney Injury: A Propensity Score-Matched Comparison.

INTRODUCTION: Evidence on the comparison of treatments for hepatorenal syndrome-acute kidney injury (HRS-AKI) in a US population is limited. An indirect comparison of terlipressin plus albumin vs midodrine and octreotide plus albumin (MO) may provide further insight into treatment efficacy. METHODS: Cohorts of patients treated for HRS-AKI characterized by inclusion of patients with serum creatinine (SCr) <5 mg/dL and baseline acute-on-chronic liver failure grades 0-2 and exclusion of patients listed for transplant if model for end-stage liver disease scores ≥35 were pooled from (i) the CONFIRM and REVERSE randomized controlled trials (N = 159 meeting eligibility criteria from N = 216 overall, treated with terlipressin) and (ii) a retrospective review of medical records from 10 US tertiary hospitals (2016-2019; N = 55 treated with MO meeting eligibility criteria from N = 200 overall). The primary end point comparing the 2 cohorts was HRS reversal defined as achieving SCr ≤1.5 mg/dL at least once during the treatment. Covariate balancing propensity scoring was used to adjust for differences in baseline characteristics. RESULTS: HRS-AKI reversal was achieved in 52.35% of terlipressin-treated patients compared with 20% of MO-treated patients (adjusted mean difference 32.35%, 95% confidence interval [CI] 17.40-47.30, P < 0.0001). Terlipressin-treated patients had increased overall survival (adjusted hazard ratio 0.57, 95% CI 0.35-0.93, P = 0.02) but similar transplant-free survival (adjusted hazard ratio 0.79, 95% CI 0.53-1.17, P = 0.24). Achievement of HRS-AKI reversal was associated with increased OS and TFS regardless of treatment ( P < 0.001). DISCUSSION: Consistent with prior reports, terlipressin plus albumin is more effective in improving kidney function and achieving HRS-AKI reversal than MO plus albumin based on indirect comparison in a US population.
