Therapeutic Drug Monitoring of Voriconazole in Patients with End-Stage Liver Disease.

BACKGROUND: This study aimed to identify the factors that influence voriconazole (VCZ) plasma concentrations and optimize the doses of VCZ in patients with end-stage liver disease (ESLD). METHODS: Patients with ESLD who received a VCZ maintenance dose of 100 mg twice daily (group A, n = 57) or the VCZ maintenance dose of 50 mg twice daily (group B, n = 37), orally or intravenously, were enrolled in this study. Trough plasma concentrations (Cmin) of VCZ between 1 and 5 mg/L were considered within the therapeutic target range. RESULTS: The VCZ Cmin was determined in 94 patients with ESLD. The VCZ Cmin of patients in group A was remarkably higher than those in group B (4.85 ± 2.53 mg/L vs 2.75 ± 1.40 mg/L; P < 0.001). Compared with group A, fewer patients in group B had VCZ Cmin outside the therapeutic target (23/57 vs. 6/37, P = 0.021). Univariate and multivariate analyses suggested that both body weight and Model for End-Stage Liver Disease scores were closely associated with the VCZ Cmin in group B. CONCLUSIONS: These data indicate that dose optimization based on body weight and Model for End-Stage Liver Disease scores is required to strike an efficacy-safety balance during VCZ treatment in patients with ESLD.

Growth Hormone Therapy in Decompensated Cirrhosis: An Open-Label, Randomized Control Trial.

INTRODUCTION: Effect of long-term growth-hormone (GH) therapy in decompensated cirrhosis (DC) is unknown. We studied the safety and efficacy of GH therapy on malnutrition, nitrogen metabolism, and hormonal changes in patients with DC. METHODS: Patients with DC were randomized to standard medical therapy plus GH (group A; n = 38) or standard medical therapy alone (group B; n = 38). Body mass index, midarm muscle circumference (MAMC), hand grip strength (HGS), liver frailty index (LFI), skeletal muscle index (SMI), nitrogen balance, Child-Turcotte-Pugh, model for end-stage liver disease, quality of life (QOL), serum albumin, GH, insulin like growth factor-1, and acid labile subunit (ALS) were assessed at baseline and at 12 months. RESULTS: The mean difference between baseline and 12-months in SMI (-6.122 [-9.460 to -2.785] cm 2 /m 2 ), body mass index (-2.078 [-3.584 to -0.5718] kg/m 2 ), MAMC (-1.960 [-2.928 to -0.9908] cm), HGS (-5.595 [-7.159 to -4.031] kg), albumin (-0.3967 [-0.6876 to -0.1057] g/dL), LFI (0.3328 [0.07786-0.5878]), Child-Turcotte-Pugh (0.9624 [0.1435-1.781]), model for end-stage liver disease (1.401 [0.04698-2.75]), insulin-like growth factor-1 (-6.295 [-11.09 to -1.495] ng/dL), and ALS (-8.728 [-14.12 to -3.341] pg/mL) were statistically significantly better ( P < 0.05) in group A. There was no improvement in nutritional parameters, clinical scores, QOL scores, or nitrogen balance in group B. The mean difference between group A and B in SMI, HGS, MAMC, LFI, ALS, physical component summary, and mental component summary at 12 months was also statistically significant. Survival at 12 months was similar in both groups ( P = 0.35). No serious adverse events were observed. DISCUSSION: Long-term use of GH is safe in DC and leads to improvement in malnutrition and possibly QOL. However, there is no improvement in 12-month survival (NCT03420144).

Effect of albumin infusion on oxidative albumin modification and albumin binding capacity in chronic liver failure.

Oxidative albumin modification and impaired albumin binding function have been described both in chronic liver failure and for therapeutic albumin solutions. The aim of the present study was to evaluate the effect of albumin infusion on redox state and binding function of circulating albumin. We studied 20 patients with cirrhosis who routinely received albumin infusions for prevention of post-paracentesis circulatory dysfunction or treatment of hepatorenal syndrome. We measured albumin fractions by redox state of cysteine-34 and albumin binding properties using dansylsarcosine as site II ligand. Therapeutic albumin solutions showed high contents of human nonmercaptalbumin-1 and human nonmercaptalbumin-2, exceeding the respective values in our patients with decompensated cirrhosis. An initial protocol for the first nine patients sampled at baseline, 24 h and 48 h after albumin infusion revealed no significant changes of oxidized albumin species or albumin binding properties. However, a modified protocol for the remaining 11 patients sampled at baseline, <1 h after and 24 h after albumin infusion revealed short-lived changes of oxidized albumin species while no changes in albumin binding properties were observed. In conclusion, therapeutic albumin infusion transiently changed albumin redox state but did not improve binding function of circulating albumin in chronic liver failure.

Characteristics of Gram-positive cocci infection and the therapeutic effect after liver transplantation. / è‚ç§»æ¤æœ¯åŽé©å °æ°é˜³æ€§çƒèŒçš„æ„ŸæŸ“ç‰¹ç‚¹åŠé˜²æ²»æ•ˆæžœ.

OBJECTIVES: Gram-positive cocci is the main pathogen responsible for early infection after liver transplantation (LT), posing a huge threat to the prognosis of liver transplant recipients. This study aims to analyze the distribution and drug resistance of Gram-positive cocci, the risk factors for infections and efficacy of antibiotics within 2 months after LT, and to guide the prevention and treatment of these infections. METHODS: In this study, data of pathogenic bacteria distribution, drug resistance and therapeutic efficacy were collected from 39 Gram-positive cocci infections among 256 patients who received liver transplantation from donation after citizens' death in the Third Xiangya Hospital of Central South University from January 2019 to July 2022, and risk factors for Gram-positive cocci infection were analyzed. RESULTS: Enterococcus faecium was the dominant pathogenic bacteria (33/51, 64.7%), followed by Enterococcus faecalis (11/51, 21.6%). The most common sites of infection were abdominal cavity/biliary tract (13/256, 5.1%) and urinary tract (10/256, 3.9%). Fifty (98%) of the 51 Gram-positive cocci infections occurred within 1 month after LT. The most sensitive drugs to Gram-positive cocci were teicoplanin, tigecycline, linezolid and vancomycin. Vancomycin was not used in all patients, considering its nephrotoxicity. Vancomycin was not administered to all patients in view of its nephrotoxicity.There was no significant difference between the efficacy of daptomycin and teicoplanin in the prevention of cocci infection (P>0.05). Univariate analysis indicated that preoperative Model for End-Stage Liver Disease (MELD) score >25 (P=0.005), intraoperative red blood cell infusion ≥12 U (P=0.013) and exposure to more than 2 intravenous antibiotics post-LT (P=0.003) were related to Gram-positive cocci infections. Multivariate logistic regression analysis revealed that preoperative MELD score >25 (OR=2.378, 95% CI 1.124 to 5.032, P=0.024) and intraoperative red blood cell transfusion ≥ 12 U (OR=2.757, 95% CI 1.227 to 6.195, P=0.014) were independent risk factors for Gram-positive cocci infections after LT. Postoperative Gram-positive cocci infections were reduced in LT recipients exposing to more than two intravenous antibiotics post-LT (OR=0.269, 95% CI 0.121 to 0.598, P=0.001). CONCLUSIONS: Gram-positive cocci infections occurring early after liver transplantation were dominated by Enterococcus faecalis infections at the abdominal/biliary tract and urinary tract. Teicoplanin, tigecycline and linezolid were anti-cocci sensitive drugs. Daptomycin and teicoplanin were equally effective in preventing cocci infections due to Gram-positive cocci. Patients with high preoperative MELD score and massive intraoperative red blood cell transfusion were more likely to suffer Gram-positive cocci infection after surgery. Postoperative Gram-positive cocci infections were reduced in recipients exposing to more than two intravenous antibiotics post-LT.

Mortality rates among patients successfully treated for hepatitis C in the era of interferon-free antivirals: population based cohort study.

OBJECTIVES: To quantify mortality rates for patients successfully treated for hepatitis C in the era of interferon-free, direct acting antivirals and compare these rates with those of the general population. DESIGN: Population based cohort study. SETTING: British Columbia, Scotland, and England (England cohort consists of patients with cirrhosis only). PARTICIPANTS: 21 790 people who were successfully treated for hepatitis C in the era of interferon-free antivirals (2014-19). Participants were divided into three liver disease severity groups: people without cirrhosis (pre-cirrhosis), those with compensated cirrhosis, and those with end stage liver disease. Follow-up started 12 weeks after antiviral treatment completion and ended on date of death or 31 December 2019. MAIN OUTCOME MEASURES: Crude and age-sex standardised mortality rates, and standardised mortality ratio comparing the number of deaths with that of the general population, adjusting for age, sex, and year. Poisson regression was used to identify factors associated with all cause mortality rates. RESULTS: 1572 (7%) participants died during follow-up. The leading causes of death were drug related mortality (n=383, 24%), liver failure (n=286, 18%), and liver cancer (n=250, 16%). Crude all cause mortality rates (deaths per 1000 person years) were 31.4 (95% confidence interval 29.3 to 33.7), 22.7 (20.7 to 25.0), and 39.6 (35.4 to 44.3) for cohorts from British Columbia, Scotland, and England, respectively. All cause mortality was considerably higher than the rate for the general population across all disease severity groups and settings; for example, all cause mortality was three times higher among people without cirrhosis in British Columbia (standardised mortality ratio 2.96, 95% confidence interval 2.71 to 3.23; P<0.001) and more than 10 times higher for patients with end stage liver disease in British Columbia (13.61, 11.94 to 15.49; P<0.001). In regression analyses, older age, recent substance misuse, alcohol misuse, and comorbidities were associated with higher mortality rates. CONCLUSION: Mortality rates among people successfully treated for hepatitis C in the era of interferon-free, direct acting antivirals are high compared with the general population. Drug and liver related causes of death were the main drivers of excess mortality. These findings highlight the need for continued support and follow-up after successful treatment for hepatitis C to maximise the impact of direct acting antivirals.

Dose-response Analysis in Hepatic Tumors Treated with 90Y-TARE According to a Personalized Dosimetric Workflow: Preliminary Results.

BACKGROUND: Transarterial Radioembolization (TARE) is a widespread radiation therapy for unresectable hepatic lesions, but a clear understanding of the dose-response link is still missing. The aim of this preliminary study is to investigate the role of both dosimetric and clinical parameters as classifiers or predictors of response and survival for TARE in hepatic tumors and to present possible response cut-off. METHODS: 20 patients treated with glass or resin microspheres according to a personalized workflow were included. Dosimetric parameters were extracted from personalized absorbed dose maps obtained from the convolution of 90Y PET images with 90Y voxel S-values. RESULTS: D95 ≥ 104 Gy and tumor mean absorbed dose MADt ≥ 229 Gy were found to be optimal cut-off values for complete response, while D30 ≥ 180 Gy and MADt ≥ 117 Gy were selected as cut-off values for at least partial response and predicted better survival. Clinical parameters Alanine Transaminase (ALT) and Model for End-Stage Liver Disease (MELD) didn't show sufficient classification capability for response or survival. CONCUSION: These preliminary results highlight the importance of an accurate dosimetric evaluation and suggest a cautious approach when considering clinical indicators. Dosimetric cut-off values could be a support tool in both planning and post-treatment phases. Larger multi-centric randomized trials, with standardized methods regarding patient selection, response criteria, Regions of Interest definition, dosimetric approach and activity planning are needed to confirm these promising results.

Effect of Prophylactic Antibiotics on Mortality in Severe Alcohol-Related Hepatitis: A Randomized Clinical Trial.

Importance: The benefits of prophylactic antibiotics for hospitalized patients with severe alcohol-related hepatitis are unclear. Objective: To determine the efficacy of amoxicillin-clavulanate, compared with placebo, on mortality in patients hospitalized with severe alcohol-related hepatitis and treated with prednisolone. Design, Setting, and Participants: Multicenter, randomized, double-blind clinical trial among patients with biopsy-proven severe alcohol-related hepatitis (Maddrey function score ≥32 and Model for End-stage Liver Disease [MELD] score ≥21) from June 13, 2015, to May 24, 2019, in 25 centers in France and Belgium. All patients were followed up for 180 days. Final follow-up occurred on November 19, 2019. Intervention: Patients were randomly assigned (1:1 allocation) to receive prednisolone combined with amoxicillin-clavulanate (n = 145) or prednisolone combined with placebo (n = 147). Main Outcome and Measures: The primary outcome was all-cause mortality at 60 days. Secondary outcomes were all-cause mortality at 90 and 180 days; incidence of infection, incidence of hepatorenal syndrome, and proportion of participants with a MELD score less than 17 at 60 days; and proportion of patients with a Lille score less than 0.45 at 7 days. Results: Among 292 randomized patients (mean age, 52.8 [SD, 9.2] years; 80 [27.4%] women) 284 (97%) were analyzed. There was no significant difference in 60-day mortality between participants randomized to amoxicillin-clavulanate and those randomized to placebo (17.3% in the amoxicillin-clavulanate group and 21.3% in the placebo group [P = .33]; between-group difference, -4.7% [95% CI, -14.0% to 4.7%]; hazard ratio, 0.77 [95% CI, 0.45-1.31]). Infection rates at 60 days were significantly lower in the amoxicillin-clavulanate group (29.7% vs 41.5%; mean difference, -11.8% [95% CI, -23.0% to -0.7%]; subhazard ratio, 0.62; [95% CI, 0.41-0.91]; P = .02). There were no significant differences in any of the remaining 3 secondary outcomes. The most common serious adverse events were related to liver failure (25 in the amoxicillin-clavulanate group and 20 in the placebo group), infections (23 in the amoxicillin-clavulanate group and 46 in the placebo group), and gastrointestinal disorders (15 in the amoxicillin-clavulanate group and 21 in the placebo group). Conclusion and Relevance: In patients hospitalized with severe alcohol-related hepatitis, amoxicillin-clavulanate combined with prednisolone did not improve 2-month survival compared with prednisolone alone. These results do not support prophylactic antibiotics to improve survival in patients hospitalized with severe alcohol-related hepatitis. Trial Registration: ClinicalTrials.gov Identifier: NCT02281929.

Response-Guided Therapy With Cefotaxime, Ceftriaxone, or Ciprofloxacin for Spontaneous Bacterial Peritonitis: A Randomized Trial: A Validation Study of 2021 AASLD Practice Guidance for SBP.

INTRODUCTION: For the treatment of spontaneous bacterial peritonitis (SBP), cefotaxime, ceftriaxone, and ciprofloxacin were used as first-line agents. However, considering the increasing rate of antibiotic resistance, it is unclear which of these drugs can be initially recommended. This study aimed to compare the current efficacy of the 3 antibiotics, namely cefotaxime, ceftriaxone, and ciprofloxacin, for the treatment of SBP in patients with cirrhosis with ascites, when guided by therapeutic responses. METHODS: This study was a multicenter, prospective, randomized controlled trial. The inclusion criteria were 16- to 75-year-old patients with liver cirrhosis with ascites, having polymorphonuclear cell count of >250/mm 3 . We performed a follow-up paracentesis at 48 hours to decide continuing or changing the assigned antibiotics and then assessed the resolution rates at 120 and 168 hours of treatment. RESULTS: A total of 261 patients with cirrhosis who developed SBP were enrolled. Most of the patients were diagnosed as those with SBP within 48 hours of admission. The resolution rates at 120 hours, which is the primary endpoint, were 67.8%, 77.0%, and 73.6% in the cefotaxime, ceftriaxone, and ciprofloxacin groups, respectively ( P = 0.388), by intension-to-treat analysis. The 1-month mortality was similar among the groups ( P = 0.770). The model for end-stage liver disease score and the SBP resolution were significant factors for survival. CONCLUSION: The efficacy of empirical antibiotics, such as cefotaxime, ceftriaxone, and ciprofloxacin, against SBP was not significantly different. In addition, these antibiotics administered based on response-guided therapy were still efficacious as initial treatment for SBP, especially in those with community-acquired infections.

Clinical Outcomes of Oral Zinc Therapy in Hepatic Encephalopathy Treatment.

BACKGROUND: Additional therapies for hepatic encephalopathy (HE) treatment are warranted. There are data evaluating the use of zinc for HE; however, clinical outcomes, specifically in the United States, are unknown. OBJECTIVE: To compare 30-day and 1-year all-cause readmission rates in patients with cirrhosis complicated by HE on lactulose and rifaximin to those on lactulose, rifaximin, and zinc. METHODS: This retrospective study included patients admitted with documented cirrhosis and home medications of lactulose and rifaximin, with or without zinc. Patients were stratified into 2 groups: those receiving lactulose and rifaximin for HE (control) and those receiving lactulose, rifaximin, and zinc for HE (treatment). The primary outcomes were 30-day and 1-year all-cause readmission rates. RESULTS: One-hundred fifty-seven patients were included (102 in control group, 55 in treatment group). Regarding 30-day and 1-year all-cause readmission rates, there was no difference between the control and treatment groups. CONCLUSION AND RELEVANCE: This is the first study conducted in the United States evaluating zinc for HE treatment. Zinc did not impact 30-day or 1-year all-cause readmission rates. Further studies are warranted to evaluate the potential benefit of zinc for HE, possibly in correlation with Model for End-stage Liver Disease-Sodium (MELD-Na) scores.

Outcome of Budd-Chiari Syndrome Patients Treated With Direct Oral Anticoagulants: An Austrian Multicenter Study.

BACKGROUND AND AIMS: Direct oral anticoagulants (DOACs) may simplify management of Budd-Chiari syndrome (BCS). Here, we report our experience with off-label use of DOACs for anticoagulation in BCS. METHODS: The safety of DOAC vs vitamin K antagonist treatment as well as associated clinical outcomes were retrospectively assessed in 47 BCS patients treated at 6 Austrian centers. RESULTS: Mean age at study inclusion was 37.9 ± 14.0 years and mean Model for End-Stage Liver Disease was 13.1 ± 5.1. Overall, 63.8% (n = 30) of patients had decompensated liver disease, and 87.2% (n = 41) showed clinical signs of portal hypertension. During a median follow-up of 82.5 (interquartile range, 43.1-121.8) months, 43 (91.5%) patients received anticoagulation alone or following interventional treatment, including 22 (46.8%) patients treated with DOACs (edoxaban: 10, apixaban: 4, rivaroxaban: 3, dabigatran: 3, more than one DOAC sequentially: 2) for a median of 24.4 (interquartile range, 5.7-35.1) months. While 72.7% (n = 16 of 22) of patients were switched from low-molecular-weight heparin (n = 12) or vitamin K antagonist (n = 4) to DOAC after disease stabilization or improvement, 27.3% (n = 6 of 22) of BCS patients were initially treated with DOAC. Complete response (European Association for the Study of the Liver criteria) was achieved or maintained in 14 (63.6%) of 22 patients, with ongoing response in 2 patients, while disease progressed in 6 patients (including 2 patients with hepatocellular carcinoma). Four major spontaneous bleedings (18.2%; incidence rate 8.8 per 100 patient-years; n = 2 upper gastrointestinal bleeding, n = 1 lower gastrointestinal bleeding, n = 1 hepatocellular carcinoma rupture), 7 minor bleedings, and 1 major procedure-related bleeding (4.5%; 2.2 per 100 patient-years) occurred during DOAC therapy. Overall transplant-free survival was 91.6% at 5 years. CONCLUSIONS: DOACs seem to be effective and safe for long-term anticoagulation in patients with BCS, but confirmation by larger prospective studies is needed.

Prothrombinex®-VF in chronic liver disease: Friend or foe?

OBJECTIVE: Management of coagulopathy in chronic liver disease (CLD) poses a challenge for critical care physicians. Prothrombinex®-VF is a low-volume product with rapid onset of action. Evidence for its efficacy and safety in CLD is limited and cases of acute intravascular coagulation and fibrinolysis (AICF) and/or disseminated intravascular coagulation (DIC) have been reported. Our objective was to evaluate the role of Prothrombinex®-VF in reversal of coagulopathy and the incidence AICF/DIC, thromboembolic events and mortality. METHODS: This was a retrospective, multi-centre study of Prothrombinex®-VF use in CLD across 11 hospitals over a 2-year period, excluding those on therapeutic anticoagulation. Patients were subclassified into acute on chronic liver failure (ACLF), acute decompensation (ADC) and compensated cirrhosis. Reversal of coagulopathy was defined as international normalised ratio (INR) <1.5× upper limit normal (ULN), prothrombin time <1.5× ULN, activated partial thromboplastin time <1.5× ULN and fibrinogen >1 g/L. Markers of AICF/DIC were recorded. RESULTS: Thirty CLD patients were included, and the median model for end-stage liver disease score was 23.5. Acute bleeding was the most common indication for Prothrombinex®-VF (60%). All had baseline coagulopathy and the majority did not achieve reversal. Key indicators of AICF/DIC were mainly observed in those with ACLF; bleeding from mucosa or lines (53%), worsening hypofibrinogenaemia (60%), worsening thrombocytopaenia (60%). The ADC and compensated cirrhosis groups were relatively unaffected. Incidence of venous thromboembolism was 6%. Overall mortality was 43% and 70% in ACLF. CONCLUSION: Prothrombinex®-VF did not lead to meaningful reversal of coagulopathy and should be used with caution in CLD. Patients with ACLF were more likely to develop AICF/DIC following Prothrombinex®-VF, although the association is uncertain. Further studies are needed to evaluate the safety and efficacy of Prothrombinex®-VF use in CLD.

Efficacy and predictive factors of glucocorticoid therapy for patients with hepatitis B virus-related acute-on-chronic liver failure.

Background and study aims: Glucocorticoid (GC) treatment for liver failure is controversial. This study sought to evaluate the efficacy and predictive factors of glucocorticoid therapy for hepatitis B virus-related acute-on-chronic liver failure (HBV- ACLF). Patients and methods: A total of 302 patients with HBV- ACLF were enrolled and categorized by treatment modality (GC vs. Control). Baseline characteristics, liver function, disease complications, and mortality were recorded. Univariate and multivariate analysis were used to identify predictive factors for HBV-ACLF-related mortality. Results: GC therapy significantly improved the 30- and 60-day mortality of HBV-ACLF patients (4.64% vs. 11.92%, P=0.022 and 16.56% vs. 25.83%, P=0.049 for the Control and GC groups, respectively) and GC was an independent prognostic factor for 30-day mortality (OR = 0.177, 95% CI 0.051-0.616, P = 0.007). However, enhanced survival was not associated with improved liver function. There were no significant differences in the incidence of complications (i.e., ascites, bacterial infection, encephalopathy, hepatorenal syndrome, and gastrointestinal bleeding) between the GC and Control groups (P >0.05), except that fungal infection occurred with higher frequency in the GC group (P = 0.037). A significant improvement in the 30-day survival associated with GC therapy was observed among patients <40 years of age, a Model for End-stage Liver Disease (MELD) score of 25-35 or a CLIF- Consortium ACLF (CLIF-C ACLF) grade 0-1 (all P <0.05). Conclusions: GC therapy improved the short-term (30- and 60- day) mortality of patients with HBV-ACLF. This treatment may be of particular benefit to patients who are <40 years of age, have a MELD score of 25-35, or have a CLIF-C ACLF grade of 0-1. (Acta gastroenterol. belg., 2022, 85, 593-600).

Association of Nationwide Hepatitis B Vaccination and Antiviral Therapy Programs With End-Stage Liver Disease Burden in Taiwan.

Importance: Chronic infections of hepatitis B and C viruses are the main causes of end-stage liver disease (ESLD) worldwide. The successful control of viral hepatitis is critical to reducing the burden of ESLD. Objective: To examine the association of 2 world-first nationwide neonatal hepatitis B vaccinations and national antiviral therapy programs implemented in Taiwan (in 1984 and 2003, respectively) with the burden of ESLD. Design, Setting, and Participants: This cohort study included children and adults aged 5 to 39 years from the National Cancer Registry Database and the National Death Registry Database between 1979 and 2018 in Taiwan. Individuals who died from chronic liver disease (CLD) and cirrhosis and hepatocellular carcinoma (HCC) or were diagnosed with HCC were included for analysis. Analyses were performed in January 2021. Main Outcomes and Measures: The main outcomes were measures of age, period, and cohort associations with CLD mortality and HCC incidence and mortality using an age-period-cohort analysis. Results: Among the 43 604 individuals (mean [SD] age, 33.3 [6.0] years; 37 755 men [86.6%]) with ESLD in the cohort, there were 17 904 CLD deaths, 11 504 HCC deaths, and 14 196 HCC incident events. There was a significant increase in all 3 disease burdens after age 20 years. From 2004 to 2018, CLD mortality decreased by 26% (adjusted rate ratio [aRR], 0.74; 95% CI, 0.70-0.82), HCC mortality decreased by 50% (aRR, 0.50; 95% CI, 0.45-0.58), and HCC incidence decreased by 53% (aRR, 0.47; 95% CI, 0.44-0.52). A sharply declining association by cohort was observed from the 1982 to 1986 birth cohort to the 2007 to 2011 birth cohort, during which CLD mortality decreased by 82% (aRR, 0.18; 95% CI, 0.00-1.13), HCC mortality decreased by 63% (aRR, 0.37; 95% CI, 0.09-0.68), and HCC incidence decreased by 80% (aRR, 0.20; 95% CI, 0.00-0.48). The associations of age, period, and cohort were similar between male and female individuals and between urban and rural areas. The percentage of chronic hepatitis B infections in patients with HCC decreased from 83.3% (95% CI, 79.7%-86.5%) for those born from 1980 to 1984 to 55.6% (95% CI, 21.2%-86.3%) (from 2000 to 2004). Conclusions and Relevance: These findings suggest that the national hepatitis B vaccination program and the antiviral therapy program jointly were associated with substantial reductions in the burden of ESLD in Taiwan.

Genetic diversity of hepatitis C virus and resistance associated substitutions to direct-acting antiviral treatment in Colombia.

Hepatitis C virus (HCV) infection is one of the leading risk factors for end-stage liver disease development worldwide. This RNA virus displays high genetic diversity with 8 genotypes and 96 subgenotypes with heterogeneous geographical distribution around the world. In this study, we carried out an active case finding of individuals with a history of transfusion events before 1996 in three cities in Colombia. Then, the characterization of the HCV genotypes, subgenotypes, and resistance associate substitutions (RAS) was performed in samples positives for antibodies anti-HCV + from this study population. In addition, samples from PWID and patients with end-stage liver disease submitted to liver transplantation were included in the phylogenetic and RAS analysis. The 5'UTR, NS5A, and NS5B regions of the HCV genome were amplified in serum or liver explants samples. After the edition, assembly, and alignment of the sequences, genotyping through phylogenetic analysis was performed using IQTREE V2.0.5 based on the maximum likelihood approach. The identification of RAS was carried out by alignments based on the reference sequence (GenBank NC_004102). Two hundred sixty individuals with blood transfusion events before 1996 were recruited. The seroprevalence of antibodies anti-HCV was 2.69% in this population. The HCV genotypes 1, 2, and 4 and subgenotypes 1a, 1b, 2a, 4a and 4d were characterized in samples of the study populations. Three RAS (Q30R, C316N, and Y93H) were identified in samples obtained from 2 individuals who received blood transfusion before 1996 and without previous antiviral treatment and 6 samples obtained from patients with end-stage liver disease. Among the 20 samples analyzed, the HCV genotype 1, subgenotype 1b, was the most frequent (60%). We report the first characterization of HCV subgenotypes 4a and 4d and the first RAS identification in patients in Colombia.

Effect of L-carnitine on quality of life in covert hepatic encephalopathy: a randomized, double-blind, placebo-controlled study.

BACKGROUND/AIMS: L-carnitine is potentially beneficial in patients with hepatic encephalopathy (HE). We aimed to evaluate the impact of L-carnitine on the quality of life and liver function in patients with liver cirrhosis and covert HE. METHODS: We conducted an investigator-initiated, prospective, multi-center, double- blind, randomized phase III trial in patients with covert HE. A total of 150 patients were randomized 1:1 to L-carnitine (2 g/day) or placebo for 24 weeks. Changes in quality of life and liver function were assessed at 6 months. The model for end-stage liver disease (MELD), the 36-Item Short Form Survey (SF-36), the psychometric hepatic encephalopathy score (PHES), and the Stroop Test were evaluated in all patients. RESULTS: The total SF-36 score significantly improved in the L-carnitine group after 24 weeks (difference: median, 2; interquartile range, 0 to 11; p < 0.001); however, these values were comparable between the two groups. Furthermore, there was a significant ordinal improvement in PHES scores among patients with minimal HE who were in the L-carnitine group (p = 0.007). Changes in the total carnitine level also positively correlated with improvements in the Stroop test in the L-carnitine group (color test, r = 0.3; word test, r = 0.4; inhibition test, r = 0.5; inhibition/switching test, r = 0.3; all p < 0.05). Nevertheless, the MELD scores at week 24 did not differ between the groups. CONCLUSION: Twenty-four weeks of L-carnitine supplementation was safe but ineffective in improving quality of life and liver function.

IL-1 receptor antagonist plus pentoxifylline and zinc for severe alcohol-associated hepatitis.

BACKGROUND AND AIMS: Patients with severe alcohol-associated hepatitis (AH) have high mortality. Corticosteroids improve survival only for 30 days. We targeted inflammation, cellular injury, and gut leakiness in a randomized clinical trial comparing combination therapy to corticosteroids on 180-day survival. APPROACH AND RESULTS: Subjects with a clinical diagnosis of severe AH (Model for End-Stage Liver Disease [MELD] >20, Maddrey discriminant function [MDF] >32) were randomized to receive methylprednisolone (PRED; 28 days) or a combination of anakinra (14 days) plus pentoxifylline (28 days) plus zinc (COMB; 180 days). The primary endpoint was survival at 180 days. The study was designed in 2013, initiated in October 2014, and completed in March 2018. Five hundred patients were screened to randomize 104 subjects with a clinical diagnosis of AH with a MELD score >20. Fifty-three patients were randomized into the COMB and 50 to the PRED treatment; 1 dropped out of the study before randomization. Mean age was 45.3 ± 10.4 years; 60.6% were males, 92.3% White, and mean MELD 25.7 ± 3.9. Kaplan-Meier survival estimate at 180 days was 67.9% in COMB and 56% in PRED (HR = 0.69; p = 0.3001). Survival curves separated by 90 days (COMB, 69.8%; PRED, 58.0%; HR = 0.69; p = 0.28). Survival at 28 days was similar between the COMB (83.4%) and PRED groups (81.2%; HR = 0.91; p = 0.85). There were no unexpected serious adverse events, and incidence of infection was comparable between groups. MELD 20-25 and MELD >26 strata showed nonsignificant treatment effects in favor of COMB. CONCLUSIONS: A combination of anakinra, pentoxifylline plus zinc provides similar survival benefits compared to corticosteroid therapy in severe AH.

From Coronaries to Cirrhosis: The Role of Percutaneous Coronary Intervention and Dual Antiplatelet Therapy in End-Stage Liver Disease.

Drug-eluting stents (DES) have superior efficacy compared with bare metal stents (BMS) for treatment of coronary artery lesions. However, BMS continue to play an important role in percutaneous coronary intervention for patients who are at a high bleeding risk, because they require a shorter duration of dual antiplatelet therapy. However, new developments in DES and understanding of the optimal time required for dual antiplatelet therapy after percutaneous coronary intervention may further limit the use of BMS. Furthermore, the use of dual antiplatelet therapy is complicated in patients with cirrhosis, who may have coagulopathy. In this article, we present the case of a patient with cirrhosis and end-stage chronic liver disease with coronary artery disease and a proximal left anterior descending stenosis who received a DES and had multiple episodes of gastrointestinal bleeding. We review the literature addressing DES and BMS in patients at high risk of bleeding. We also review the optimal duration of dual antiplatelet therapy.

Clinical efficacy of antiviral therapy in patients with hepatitis B-related cirrhosis after transjugular intrahepatic portosystemic shunt.

BACKGROUND: As a country with a high burden of hepatitis B, China has about 86 million cases of hepatitis B virus infection, ranking the first in the world. Currently, there are about 390000 deaths due to hepatitis B-related complications such as liver cirrhosis and liver cancer every year. Consequently, how to control portal hypertension, improve liver functional reserve, and reduce the incidence of hepatic failure and liver cancer in such patients is the focus of current clinical attention. Previous clinical study in our center suggested that at 24 mo after transjugular intrahepatic portosystemic shunt (TIPS), the liver functional reserve of patients with hepatitis B cirrhosis was better than that of patients with alcohol-induced and immune cirrhosis, which may be related to the effective etiological treatment. AIM: To investigate the clinical efficacy of three first-line antiviral drugs recommended by the guidelines of prevention and treatment for chronic hepatitis B in China (2019) in the treatment of patients with hepatitis B-related cirrhosis who had received a TIPS. METHODS: The clinical data of 137 patients with hepatitis B-related cirrhosis with portal hypertension after receiving TIPS at our centre between March 2016 and December 2020 were analysed retrospectively. According to different anti-viral drugs, the patients were divided into entecavir (ETV) (n = 70), tenofovir alafenamide fumarate (TAF) (n = 32), and tenofovir disoproxil fumarate (TDF) (n = 35) groups. The cumulative incidence of hepatic encephalopathy and hepatocellular carcinoma, survival, and changes in hepatic reserve function and glomerular filtration rate in patients treated with different antiviral drugs within 24 mo after surgery were investigated. RESULTS: At 24 mo after surgery, the Child-Pugh score in the TAF group (6.97 ± 0.86) was lower than that in the TDF (7.49 ± 0.82; t = -2.52, P = 0.014) and ETV groups (7.64 ± 1.17; t = -2.92, P = 0.004). The model for end-stage liver disease score in the TAF group at 24 mo after surgery was 9.72 ± 1.5, which was lower than that in the TDF (10.74 ± 2.33; t = -2.09, P = 0.040) and ETV groups (10.97 ± 2.17; t = -2.93, P = 0.004). At 24 mo after surgery, the estimated glomerular filtration rate (eGFR) in the TAF group (104.41 ± 12.54) was higher than that in the TDF (93.54 ± 8.97) and ETV groups (89.96 ± 9.86) (F = 21.57, P < 0.001). CONCLUSION: At 24 mo after surgery, compared with TDF and ETV, TAF has significant advantages in the improvement of liver functional reserve and eGFR.

Ubiquitin pathways regulate the pathogenesis of chronic liver disease.

Chronic liver disease (CLD) is considered the leading cause of global mortality. In westernized countries, increased consumption of alcohol and overeating foods with high fat/ high glucose promote progression of CLD such as alcoholic liver disease (ALD) and non-alcoholic liver disease (NAFLD). Accumulating evidence and research suggest that ubiquitin, a 75 amino acid protein, plays crucial role in the pathogenesis of CLD through dynamic post-translational modifications (PTMs) exerting diverse cellular outcomes such as protein degradation through ubiquitin-proteasome system (UPS) and autophagy, and regulation of signal transduction. In this review, we present the function of ubiquitination and latest findings on diverse mechanism of PTMs, UPS and autophagy which significantly contribute to the pathogenesis of alcoholic liver disease (ALD), non-alcoholic fatty liver disease (NAFLD), cirrhosis, and HCC. Despite its high prevalence, morbidity, and mortality, there are only few FDA approved drugs that could be administered to CLD patients. The goal of this review is to present a variety of pathways and therapeutic targets involving ubiquitination in the pathogenesis of CLD. Further, this review summarizes collective views of pharmaceutical inhibition or activation of recent drugs targeting UPS and autophagy system to highlight potential targets and new approaches to treat CLD.

Comparison of the impact of chronic corticosteroid therapy on critical care outcomes of COVID-19 patients with and without history of chronic liver disease.

There is a paucity of studies investigating the impact of chronic corticosteroid use for coexisting conditions in patients with Coronavirus Disease 2019 (COVID-19). Additionally, the information regarding the impact of chronic liver disease (CLD) on COVID-19 outcomes is evolving. Our study aims to investigate hospitalization outcomes of patients with COVID-19 on long term corticosteroids for coexisting conditions while also seeking to compare outcomes between such patients with a history of CLD to analyze the impact on mortality. We conducted a retrospective chart review across our 10-hospital network identifying patients on chronic corticosteroids (Prednisone ≥ 5 mg daily dose or equivalent dose of another steroid, for a duration of 30 days or more) who were hospitalized with COVID-19 from March 1, 2020 to June 30, 2020. Of these patients who met inclusion criteria, patients were then divided into groups based upon their history of CLD. Primary outcomes of the study looked to investigate the hospitalization outcomes of patients with a history of CLD and comorbid conditions requiring chronic corticosteroid use. Secondary outcomes sought to further investigate risk factors for mortality in our study sample. 837 charts were reviewed. 139 patients met inclusion criteria of which 34 patients had a history of CLD. Statistical analysis demonstrated no difference in length of hospital stay but increased ICU admission rate in the CLD group (41.2% vs 23.8%). No statistically significant difference was seen in between the CLD and non-CLD groups in term of complication rates and 28-day mortality. However, chronic corticosteroids patients were found to have higher rates of ICU admission and overall 28-day and ICU mortality in comparison to patients who were not on chronic corticosteroids prior to COVID-19 hospitalization. The larger contributor to COVID-19 severity was likely chronic corticosteroid use rather than CLD and thus chronic corticosteroid use should be limited throughout the COVID-19 pandemic especially in patients with additional speculated risk factors for COVID-19 such as CLD.
