RESUMO

BACKGROUND AND AIMS: 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 comprised of liver transplant (LT) candidates. METHODS AND RESULTS: Fifty hospitalized, LT-eligible patients with HRS-AKI received a single bolus followed by continuous terlipressin infusion. ACLF grade 3, serum creatinine (SCr)>5.0 mg/dL, or MELD≥35 were exclusions. Fifty hospitalized patients who received midodrine and octreotide (M&O) or norepinephrine (NorEpi) for HRS-AKI served as a historical comparator cohort. Complete response (CR) was defined as ≥30% decrease in SCr with EOT SCr≤1.5, partial response (PR) as ≥30% decrease in SCr with EOT SCr>1.5, and non-response (NR) as <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 hypoxic respiratory failure that responded to diuretics; one possibly had drug-related rash. CONCLUSIONS: 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 M&O/NorEpi cohort; LT-alone was accomplished in a high proportion of complete terlipressin responders.

RESUMO

Liver transplantation offers the best survival for patients with early-stage hepatocellular carcinoma (HCC). Prior studies have demonstrated disparities in transplant access; none have examined the early steps of the transplant process. We identified determinants of access to transplant referral and evaluation among patients with HCC with a single tumor either within Milan or meeting downstaging criteria in Georgia.Population-based cancer registry data from 2010 to 2019 were linked to liver transplant centers in Georgia. Primary cohort: adult patients with HCC with a single tumor ≤8 cm in diameter, no extrahepatic involvement, and no vascular involvement. Secondary cohort: primary cohort plus patients with multiple tumors confined to one lobe. We estimated time to transplant referral, evaluation initiation, and evaluation completion, accounting for the competing risk of death. In sensitivity analyses, we also accounted for non-transplant cancer treatment.Among 1,379 patients with early-stage HCC in Georgia, 26% were referred to liver transplant. Private insurance and younger age were associated with increased likelihood of referral, while requiring downstaging was associated with lower likelihood of referral. Patients living in census tracts with ≥20% of residents in poverty were less likely to initiate evaluation among those referred [cause-specific hazard ratio (csHR): 0.62, 95% confidence interval (CI): 0.42-0.94]. Medicaid patients were less likely to complete the evaluation once initiated (csHR: 0.53, 95% CI: 0.32-0.89).Different sociodemographic factors were associated with each stage of the transplant process among patients with early-stage HCC in Georgia, emphasizing unique barriers to access and the need for targeted interventions at each step. SIGNIFICANCE: Among patients with early-stage HCC in Georgia, age and insurance type were associated with referral to liver transplant, race, and poverty with evaluation initiation, and insurance type with evaluation completion. Opportunities to improve transplant access include informing referring providers about insurance requirements, addressing barriers to evaluation initiation, and streamlining the evaluation process.

RESUMO

Background: Hepatorenal syndrome-acute kidney injury (HRS-AKI) carries significant morbidity and mortality among those with end-stage liver disease. Bolus terlipressin for treatment of HRS-AKI received FDA approval in September 2022. US implementation of terlipressin, however, is hindered by the paucity of local data on the optimal patient population and administration mode, as well as the effect on transplant priority. The INFUSE study is designed to evaluate the use of continuous terlipressin infusion among transplant candidates with advanced liver disease and HRS-AKI. Methods: Fifty prospective patients with HRS-AKI will receive a single bolus of terlipressin 0.5 mg followed by continuous infusions of terlipressin from 2 to 8 mg/day for up to 14 days. The cohort will be enriched with those listed, in evaluation, or eligible for liver transplantation, while those with ACLF grade 3, MELD ≥35, and serum creatinine >5.0 mg/dL will be excluded. Fifty patients who received midodrine plus octreotide or norepinephrine for HRS-AKI will serve as a retrospective comparator cohort. Conclusion: The INFUSE study aims to assess the safety and efficacy of continuous terlipressin infusion among largely transplant-eligible patients with HRS-AKI, and to provide US-based data on transplant outcomes. This novel study design simultaneously mitigates terlipressin adverse events while providing renal benefits to patients, thus addressing the unmet medical need of those with HRS-AKI who have limited treatment options and are awaiting liver transplantation in the US.

RESUMO

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.

RESUMO

BACKGROUND AND AIMS: Organs from hepatitis C virus (HCV)-viremic donors have been used in HCV-uninfected recipients (D+/R-), but the optimal treatment approach has not been defined. We evaluated the kinetics of HCV infection following transplant in D+/R- kidney-transplant (KT) and liver-transplant (LT) recipients when a preemptive antiviral strategy was used. APPROACH AND RESULTS: Six US transplant programs prospectively treated D+/R- primary LT and KT recipients with sofosbuvir-velpastasvir for 12 weeks starting once viremia was confirmed following transplant and the patients were judged to be clinically stable, including estimated glomerular filtration rate >30 mL/min. Primary endpoints were sustained virologic response at 12 weeks following transplant and safety (assessed by proportion of treatment-related adverse and serious adverse events). Of the 24 patients transplanted (13 liver, of whom 2 had prior-treated HCV infection; 11 kidney), 23 became viremic after transplant. The median (interquartile range) time from transplant to start of antiviral therapy was 7.0 (6.0, 12.0) versus 16.5 (9.8, 24.5) days, and the median (interquartile range) HCV-RNA level 3 days after transplant was 6.5 (3.9, 7.1) versus 3.6 (2.9, 4.0) log10  IU/mL in LT versus KT recipients, respectively. By week 4 of treatment, 10 of 13 (77%) LT, but only 2 of 10 (20%) KT, had undetectable HCV RNA (P = 0.01). At the end of treatment, all LT recipients were HCV RNA-undetectable, whereas 3 (30%) of the kidney recipients still had detectable, but not quantifiable, viremia. All achieved sustained virologic response at 12 weeks following transplant (lower 95% confidence interval bound: 85%). Serious adverse events considered possibly related to treatment were antibody-mediated rejection, biliary sclerosis, cardiomyopathy, and graft-versus-host disease, with the latter associated with multiorgan failure, premature treatment discontinuation, and death. CONCLUSIONS: Despite differing kinetics of early HCV infection in liver versus non-liver recipients, a preemptive antiviral strategy is effective. Vigilance for adverse immunologic events is warranted.

RESUMO

INTRODUCTION: Pre-transplant locoregional therapy for hepatocellular carcinoma (HCC) during bridge-to-transplant impacts recurrence and survival rates following liver transplantation. Optimizing the effectiveness of transarterial chemoembolization (TACE) in this population is imperative, and microvalve infusion catheters offer a means of such improvement. METHODS: All treatment-naive patients with solitary HCC tumors < 6.5 cm who underwent drug-eluting microspheres (DEM) TACE between 04/2015 and 08/2017 were retrospectively reviewed. Eighty-eight included patients underwent DEM-TACE with either standard end-hole catheters (EH) or microvalve infusion catheters (MVI). The EH (n = 70) and MVI (n = 18) cohorts had similar baseline tumor size, laboratory values, and tumor etiologies. RESULTS: Initial objective response rates were significantly higher in MVI vs. EH (100% vs. 76.5%, p = 0.019). There was no difference in adverse events between groups (p = 0.265). MVI patients exhibited lower AST (p = 0.003) and ALT (p = 0.044) at 6 months. Blinded pathological analysis of explanted livers showed greater concentrations of microspheres within the tumor relative to the surrounding tissue in MVI explants (88.7 ± 10.6%) versus the EH explants (55.3 ± 32.7%) (p = 0.002). There was significantly higher percentage tumor necrosis in the MVI group (89.0 ± 2.2%) compared with the EH group (56.1 ± 44.5%) (p = 0.006). CONCLUSION: In this retrospective study of a single-center cohort, DEM-TACE procedures with MVI were associated with improved tumor response, increased deposition of microspheres within tumor tissue, and higher percentage tumor necrosis at explant relative to those performed using EH catheters.

RESUMO

BACKGROUND & AIMS: Caspase-mediated apoptosis and inflammation contribute to progression of liver disease. Emricasan is a pan-caspase inhibitor that reduced serum markers of apoptosis and liver inflammation in patients with hepatitis C and non-alcoholic steatohepatitis (NASH). METHODS: We performed a multicenter study of 86 patients with cirrhosis (Child-Pugh class A or B; mean score, 6.9; 38% with alcohol-associated cirrhosis, 29% with HCV-associated cirrhosis, and 23% with NASH) and model for end-stage liver disease (MELD) scores of 11-18 (mean, 12.8). Patients were randomly assigned to groups given placebo (N = 42) or Emricasan (25 mg, N = 44), twice daily for 3 months; subjects then received open-label Emricasan (25 mg) twice-daily for 3 months. The primary endpoint was the change from baseline in serum levels of cleaved keratin 18 (CK-18) at month 3. RESULTS: Seventy-four patients completed the 3-month study period (40 given Emricasan and 34 given placebo); 69 patients received open-label Emricasan for 3 months afterward. At the 3-month timepoint, Emricasan significantly reduced mean MELD (P = .003) and Child-Pugh (P = .003) scores in subjects with high MELD scores (15 or more), compared with placebo, with significant reductions in INR (95% CI, -0.2882 to -0.0866) and total bilirubin (95% CI, -1.5069 to -0.0823) vs placebo. There were no significant differences between Emricasan and placebo groups in mean MELD (P = .466) or Child-Pugh (P = .124) scores overall at 3 months compared to placebo. Of patients with high MELD scores, 6/9 given Emricasan (67%) had a reduction of 2 points or more at month 3, compared with 2/10 given placebo (20%). Serum levels of full-length CK-18 (P = .02) and caspase 3/7 (P < .001), but not cleaved CK-18 (P = .092), decreased significantly at 3 months in the Emricasan vs placebo group. Emricasan was well tolerated, and adverse events were balanced between groups. Emricasan's effects were generally maintained or increased after 6 months of treatment. CONCLUSIONS: In a randomized trial of patients with cirrhosis, we found 3 months treatment with Emricasan to improve liver function, compared with placebo, reducing MELD and Child-Pugh scores, INR, and total bilirubin in patients with MELD scores ≥15.

RESUMO

OBJECTIVES: Our objective was to determine the safety, efficacy, and pharmacokinetics of telaprevir plus pegylated interferon alfa 2a and ribavirin for chronic, posttransplant genotype 1 hepatitis C virus infection. MATERIALS AND METHODS: A prospective, single-arm, multicenter, open-label, phase 2b study was conducted at 22 North American sites to assess the safety, efficacy, and pharmacokinetics of pegylated interferon alfa 2a, ribavirin, and twice daily telaprevir in liver transplant recipients with recurrent, chronic hepatitis C without cirrhosis. Baseline liver biopsies were read by a central pathologist. There were planned safety reviews after a sentinel cohort reached treatment weeks 4 and 16. Serial pharmacokinetic sampling was performed for calcineurin inhibitors, telaprevir, and ribavirin. RESULTS: Sixty-one patients were enrolled and received ≥ 1 dose of study medication; 37 (61%) achieved sustained virologic response. Thirteen of 18 treatment-naive patients (72%), 10 of 11 patients with no or minimal fibrosis (91%), 13 of 15 patients (87%) with interleukin 28B genotype CC, and 36 of 45 patients (80%) with either undetectable or unquantifiable hepatitis C virus RNA at treatment week 4 achieved sustained virologic response. Nine patients (15%) had ≥ 1 drug-related serious adverse event and 7 (11%) discontinued all study drugs due to an adverse event. There were no deaths or acute cellular rejection episodes. During telaprevir treatment, median doses of tacrolimus and cyclosporine were 0.5 mg weekly and 25 mg daily. Target exposures were achieved for telaprevir with twice daily dosing and for ribavirin with reduced initial dosing. CONCLUSIONS: Telaprevir combination therapy for posttransplant hepatitis C virus infection yielded superior efficacy than historical controls. Adverse events were similar to, but exceeded, those in immunocompetent patients. Calcineurin inhibitor dosing levels were substantially reduced with telaprevir.

RESUMO

OBJECTIVES: To measure prescribed time to therapy (TtT) and sustained virologic response (SVR). Secondary objectives were to assess insurance appeals and copay assistance amount facilitated by a local specialty pharmacy (LSP). METHODS: This descriptive, retrospective study used a joint clinical and pharmacy database of patients who were prescribed direct-acting antivirals (DAAs) at a single-center liver specialty clinic and received LSP services from December 2013 to December 2015. RESULTS: Among 388 patients prescribed DAAs, 364 (94%) patients, who were 18 years of age or older, initiated DAA therapy, and received LSP services, were included in the study. Of these, 211 (58.0%) had cirrhosis, 159 (43.7%) had previous treatment, and 57 (15.7%) had previous liver transplants. Most patients had commercial insurance (n = 249; 68.4%), and 295 (81.0%) required prior authorization. Insurance initially denied coverage to 70 patients (19.2%), for who the LSP drafted appeals for 60 (85.7%). Copay information was available for 154 LSP patients. Although 66 had initial copays of more than $20 per month, the LSP was able to assist most (98.1%; n = 151) with copay reductions to $20 or less. Full financial assistance was received for 20 patients without insurance or any DAA coverage. Among 171 patients with SVR and prescribed TtT information, mean TtT was 12 days (median 4 days), and most received medications within 10 days (n = 122; 71.3%). The overall intention-to-treat SVR rate was 86.8%; the per-protocol (PP) SVR rate was 93.8%. CONCLUSION: Collaboration between providers and an LSP minimized delay in therapy, lowered rates of DAA denial, facilitated patient financial assistance, and helped to optimize clinical outcomes. The PP-SVR rate for this study was similar to rates reported in the literature and higher than expected, considering the inclusion of earlier-generation DAAs and many patients with advanced liver disease.

RESUMO

Although chronic hepatitis C is still the leading indication for liver transplantation (LT) in the United States and Europe, acute liver failure caused by hepatitis C is distinctly uncommon and transplantation for fulminant hepatitis C virus (HCV) has not been documented in the United States. We present a case report of fulminant hepatic failure caused by genotype 2a/c HCV not only treated with LT but also complicated by severe, rapid recurrence of HCV within 6 days of transplantation. The risk factor for the initial infection was likely sexual, and there were no explanations for acute hepatitis post-transplant other than recurrent hepatitis C. Treatment with all-oral direct antiviral agents was swiftly initiated during the index hospitalization, leading to resolution of the acute hepatitis and resulting in sustained virologic response. It can only be speculated whether this was an infection with the JFH-1 strain or another similarly virulent genotype 2a/c HCV infection.

RESUMO

Gastrointestinal neuroendocrine tumors (NET) are rare but the age-adjusted incidence in the United States has increased, possibly due to improved radiographic and endoscopic detection. In advanced NET, hepatic metastases are common. Orthotopic liver transplant (OLT) is currently considered an acceptable therapy for selected patients with limited hepatic disease or liver metastases where complete resection is thought to have curative intent. The development of NET of donor origin is very uncommon after organ transplant, and it is unclear if the same treatment strategies applied to hepatic NET would also be efficacious after OLT. Here, we describe a unique case of an OLT recipient with a donor-derived NET that was treated with redo OLT as the primary therapy. The donor-derived NET recurred in the recipient's second liver allograft suggesting an extrahepatic reservoir. This case describes the natural history of such a rare event. Here, we highlight the treatment options for hepatic NET and challenge the role of OLT for a donor-derived hepatic NET.

RESUMO

BACKGROUND: Telaprevir (TVR) plus peginterferon-α2a (PEG-IFN-α2a) and ribavirin substantially increases treatment efficacy for genotype 1 chronic hepatitis C virus (HCV) infection versus PEG-IFN-α2a-ribavirin alone. Its safety and efficacy in patients with HCV and HIV-1 are unknown. OBJECTIVE: To assess the safety and efficacy of TVR plus PEG-IFN-α2a-ribavirin in patients with genotype 1 HCV and HIV-1 and to evaluate pharmacokinetics of TVR and antiretrovirals during coadministration. DESIGN: Phase 2a, randomized, double-blind, placebo-controlled study. (ClinicalTrials.gov: NCT00983853). SETTING: 16 international multicenter sites. PATIENTS: 62 patients with HCV genotype 1 and HIV-1 who were HCV treatment-naive and receiving 0 or 1 of 2 antiretroviral regimens were randomly assigned to TVR plus PEG-IFN-α2a-ribavirin or placebo plus PEG-IFN-α2a-ribavirin for 12 weeks, plus 36 weeks of PEG-IFN-α2a-ribavirin. MEASUREMENTS: HCV RNA concentrations. RESULTS: Pruritus, headache, nausea, rash, and dizziness were higher with TVR plus PEG-IFN-α2a-ribavirin during the first 12 weeks. During this period, serious adverse events occurred in 5% (2 in 38) of those receiving TVR plus PEG-IFN-α2a-ribavirin and 0% (0 in 22) of those receiving placebo plus PEG-IFN-α2a-ribavirin; the same number in both groups discontinued treatment due to adverse events. Sustained virologic response occurred in 74% (28 in 38) of patients receiving TVR plus PEG-IFN-α2a-ribavirin and 45% (10 in 22) of patients receiving placebo plus PEG-IFN-α2a-ribavirin. Rapid HCV suppression was seen with TVR plus PEG-IFN-α2a-ribavirin (68% [26 in 38 patients] vs. 0% [0 in 22 patients] undetectable HCV RNA levels by week 4). Two patients had on-treatment HCV breakthrough with TVR-resistant variants. Patients treated with antiretroviral drugs had no HIV breakthroughs; antiretroviral exposure was not substantially modified by TVR. LIMITATION: Small sample size and appreciable dropout rate. CONCLUSION: In patients with HCV and HIV-1, more adverse events occurred with TVR versus placebo plus PEG-IFN-α2a-ribavirin; these were similar in nature and severity to those in patients with HCV treated with TVR. With or without concomitant antiretrovirals, sustained virologic response rates were higher in patients treated with TVR versus placebo plus PEG-IFN-α2a-ribavirin.

RESUMO

The following is a case report of a primiparous woman who developed fulminant liver failure in the setting of HELLP syndrome complicated by hepatic rupture. It is unique in that a timely ABO compatible liver donor was unavailable, necessitating the transplantation of an ABO incompatible organ. Despite aggressive therapy, severe reperfusion injury and humoral rejection dictated retransplantation with an ABO compatible organ on postoperative day 15, resulting in rapid clinical recovery.

RESUMO

BACKGROUND & AIMS: Noncirrhotic portal hypertension (NCPH) is unusual in North American patients. This study characterized patients with NCPH and human immunodeficiency virus-1 (HIV-1) infection to identify potential risk factors for this association. METHODS: Eleven consecutive patients from our urban hepatology clinic with HIV-1 infection and NCPH were the subject of this series. Case histories, including medication lists and laboratory data, were analyzed. RESULTS: Age at diagnosis was 51 +/- 7 years. CD4 count was 303 +/- 185 cells/mL, and HIV viral load was <75 copies/mL in 9 patients. Didanosine was the only medication taken by all patients; 10 each had taken lamivudine and zidovudine. In the 10 patients tested, 8 had at least 1 thrombophilic abnormality; 6 were deficient in protein S, and 2 had multiple abnormalities. Nodular regenerative hyperplasia was observed in all 11 and portal venulopathy in 5 patients. All patients had esophageal varices; 3 developed variceal bleeding. Six patients had ascites; 2 required transjugular intrahepatic portal systemic shunt. CONCLUSIONS: Exposure to didanosine and/or a hypercoagulable tendency might predispose patients infected with HIV-1 to vascular changes resulting in NCPH.

RESUMO

Drug-induced liver disease accounts for about 50% of acute or subacute liver failure in the United States. United Network of Organ Sharing (UNOS) data suggest 8%-20% of liver transplantation in this country per year is for fulminant liver failure due to drugs. Even though the most common medication implicated in acute liver injury is acetaminophen (75%), there are numerous other drugs that are responsible for acute and chronic liver injury. A variety of antifungal medications are known to cause a wide range of liver injury from a mild hepatocellular-cholestatic injury pattern to acute/subacute liver failure. Terbinafine is one of the antifungals that have been associated with such liver injuries. We report a case of terbinafine-induced severe liver failure requiring liver transplantation.
