RESUMO

BACKGROUND: Patients who are chronically infected with hepatitis C virus (HCV) and who do not have a sustained virologic response after treatment with regimens containing direct-acting antiviral agents (DAAs) have limited retreatment options. METHODS: We conducted two phase 3 trials involving patients who had been previously treated with a DAA-containing regimen. In POLARIS-1, patients with HCV genotype 1 infection who had previously received a regimen containing an NS5A inhibitor were randomly assigned in a 1:1 ratio to receive either the nucleotide polymerase inhibitor sofosbuvir, the NS5A inhibitor velpatasvir, and the protease inhibitor voxilaprevir (150 patients) or matching placebo (150 patients) once daily for 12 weeks. Patients who were infected with HCV of other genotypes (114 patients) were enrolled in the sofosbuvir-velpatasvir-voxilaprevir group. In POLARIS-4, patients with HCV genotype 1, 2, or 3 infection who had previously received a DAA regimen but not an NS5A inhibitor were randomly assigned in a 1:1 ratio to receive sofosbuvir-velpatasvir-voxilaprevir (163 patients) or sofosbuvir-velpatasvir (151 patients) for 12 weeks. An additional 19 patients with HCV genotype 4 infection were enrolled in the sofosbuvir-velpatasvir-voxilaprevir group. RESULTS: In the three active-treatment groups, 46% of the patients had compensated cirrhosis. In POLARIS-1, the rate of sustained virologic response was 96% with sofosbuvir-velpatasvir-voxilaprevir, as compared with 0% with placebo. In POLARIS-4, the rate of response was 98% with sofosbuvir-velpatasvir-voxilaprevir and 90% with sofosbuvir-velpatasvir. The most common adverse events were headache, fatigue, diarrhea, and nausea. In the active-treatment groups in both trials, the percentage of patients who discontinued treatment owing to adverse events was 1% or lower. CONCLUSIONS: Sofosbuvir-velpatasvir-voxilaprevir taken for 12 weeks provided high rates of sustained virologic response among patients across HCV genotypes in whom treatment with a DAA regimen had previously failed.

RESUMO

The emergence of effective direct-acting antiviral (DAA) agents has reignited discussion over the potential for hepatitis C elimination in the United States. Eliminating hepatitis C will require a critical examination of technical feasibility, economic considerations, and social/political attention. Tremendous advancement has been made with the availability of sensitive diagnostic tests and highly effective DAAs capable of achieving sustained viral response (SVR) in more than 95% of patients. Eliminating hepatitis C also requires escalating existing surveillance networks to monitor for new epidemics. All preventive interventions such as clean syringe and needle exchange programs, safe injection sites, opioid substitution therapies, and mental health services need to be expanded. Although costs of DAAs have raised budget concerns for hepatitis C elimination, studies have shown that eliminating hepatitis C will produce a savings of up to 6.5 billion USD annually along with other intangible benefits such as increased work productivity and quality of life. Economic models and meta-analyses strongly suggest universal hepatitis C screening for all adults rather than just for birth cohort and high-risk populations. Social and political factors are at least as important as technical feasibility and economic considerations. Due to lack of promotion and public awareness, HCV elimination efforts continue to receive inadequate funding. Social stigma continues to impede meaningful policy changes. Eliminating hepatitis C is an attainable public health goal that will require intense collaboration and sustained public support. (Hepatology 2018;67:2449-2459).

RESUMO

BACKGROUND: Hepatocellular carcinoma (HCC) accounts for 90% of primary hepatic malignancies. With the exception of chronic hepatitis B (CHB), other etiologies of chronic liver disease require progression to cirrhosis before HCC development. Case reports have described HCC in noncirrhotic patients with hepatitis C (HCV) and nonalcoholic fatty liver disease. GOAL: The aim of this study was to determine the prevalence of patients without cirrhosis and CHB who developed HCC among a large cohort of HCC patients and to identify independent variables that are associated with no cirrhosis among patients with HCC. STUDY: From 2005 to 2015, hepatobiliary cancer patients seen in our liver cancer and liver transplant clinics were evaluated. Patients were included if above18 years old and had histologically confirmed HCC from liver biopsy, resection specimen, or explanted livers. Patients with CHB, non-HCC tumors, or missing paired tumor and nontumor liver histology were excluded. Demographic information, pertinent laboratory values, and comorbid conditions were recorded. Potential predictors were evaluated using both backward stepwise logistic regression model and classification tree model. RESULTS: Of the 1927 patients screened, 545 HCC patients (411 transplanted, 43 resected, 74 transarterial chemoembolization/radiofrequency ablation, 17 untreated) included, 29 (5.3%) patients had no cirrhosis histologically. Eleven patients had HCV, 3 had alcoholic liver disease, 3 had nonalcoholic fatty liver, and 12 had cryptogenic liver disease. Logistic regression models show that patients with hyperlipidemia and elevated serum alanine aminotransferase are more likely to develop HCC without cirrhosis (odds ratio, 1.73 and 0.40; P<0.05). CONCLUSIONS: This large cohort, histology-confirmed case-controlled study shows that patients with nonalcoholic fatty liver disease and hyperlipidemia with elevated serum alanine aminotransferase (most likely nonalcoholic steatohepatitis) are significantly associated with the development of HCC in the absence of cirrhosis.

RESUMO

BACKGROUND: Limited data exist with regard to treatment outcomes in Asian Americans with chronic hepatitis C (CHC). We evaluated sofosbuvir (SOF)-based regimens in a national cohort of Asian Americans. METHODS: Eligible Asian Americans patients with CHC who had posttreatment follow-up of 24 weeks for SOF -based therapies from December 2013 to June 2017 were enrolled from 11 sites across the United States. The primary endpoint was sustained virologic response (SVR) rates at posttreatment weeks 12 and 24. Secondary endpoints were to evaluate safety by tolerability and adverse events (AEs). RESULTS: Among 231 patients screened, 186 were enrolled. At baseline, 31% (57/186) patients were cirrhotic, 34% (63/186) were treatment experienced. Most of the subjects (42%, 79/186) received ledispavir/SOF therapy. The overall SVR12 was 95%, ranging from 86% in genotype (GT) 1b on SOF+ribavirin to 100% in GT 1b patients on ledipasvir/SOF at subgroup analyses. SVR12 was significantly lower in cirrhotic than in noncirrhotic patients [88% (50/57) vs. 98% (126/129), P<0.01]. Stratified by GT, SVR12 were: 96% (43/45) in GT 1a; 93% (67/72) in GT 1b; 100% (23/23) in GT 2; 90% (19/21) in GT 3; 100% (1/1) in GT 4; 83% (5/6) in GT 5; and 100% (16/16) in GT 6. Cirrhotic patients with treatment failure were primarily GT 1, (GT 1a, n=2; GT 1b, n=4) with 1 GT 5 (n=1). Patients tolerated the treatment without serious AEs. Late relapse occurred in 1 patient after achieving SVR12. CONCLUSIONS: In Asian Americans with CHC, SOF-based regimens were well tolerated without serious AEs and could achieve high SVR12 regardless of hepatitis C viral infection GT.

RESUMO

In a long-term (10-year) study of radiofrequency ablation (RFA) of hepatocellular carcinoma (HCC) as bridging therapy in patients listed for orthotopic liver transplantation (LT), we evaluated the impact of RFA on waiting list dropout rate, post-LT tumor recurrence, and long-term intention-to-treat, disease-specific survival (DSS). From March 2004 to October 2014, RFA was performed as the initial stand-alone bridge therapy to LT for 121 patients (men/women ratio, 83:38; mean age, 60.0 years) with 156 de novo HCCs (mean size, 2.4 cm). Follow-up period from initial RFA ranged from 1.3 to 128.0 months (median, 42.9 months). We assessed the overall and tumor-specific waiting list dropout rates, post-LT tumor recurrence, and 10-year post-LT and intention-to-treat survival rates. Dropout from the waiting list due to tumor progression occurred in 7.4% of patients. HCC recurrence after LT occurred in 5.6% of patients. The post-LT overall survival (OS) rate at 5 and 10 years was 75.8% and 42.2%, respectively, and the recurrence-free survival (RFS) rate was 71.1% and 39.6%, respectively. Intention-to-treat OS, RFS, and DSS rates for the entire study population at 5 and 10 years were 63.5% and 41.2%, 60.8% and 37.7%, and 89.5% and 89.5%, respectively. CONCLUSION: RFA as a first-line stand-alone bridge therapy to LT achieves excellent long-term overall and tumor-specific survivals, with a low dropout rate from tumor progression despite long wait list times and a sustained low tumor recurrence rate upon post-LT follow-up of up to 10 years.

RESUMO

BACKGROUND: The number of patients needing liver transplantation (LT) exceeds the number of available allografts. The current opioid epidemic in this country has increased the number of potential donors infected with hepatitis C (HCV). METHODS: We assessed the incremental cost-effectiveness ratio (ICER) by comparing the costs and number of liver transplants performed using HCV-positive and HCV-negative grafts into patients without HCV infection in a decision analysis model with a 1-year time horizon. RESULTS: The use of HCV-positive grafts was found to have an ICER below $50 000 across all MELD scores. Using our baseline cohort with a model for end-stage liver disease (MELD) score of 15-22, the ICER was $21 233/additional LT performed. As the MELD scores increased, the ICER decreased. Above a MELD score of 23, the use of HCV-positive grafts became cost saving (-$115 419). Our model was robust to all variables tested in the sensitivity analyses, except drug costs. CONCLUSION: The results of our decision analysis model highlight the potential pharmacoeconomic benefit of utilizing HCV-positive grafts in LT candidates who are not infected with HCV. The use of HCV-positive grafts is at least cost effective and even cost saving in patients with MELD scores above 23.

RESUMO

BACKGROUND & AIMS: Studies are needed to determine the optimal regimen for patients with chronic hepatitis C virus (HCV) genotype 2, 3, 4, or 6 infections whose prior course of antiviral therapy has failed, and the feasibility of shortening treatment duration. We performed a phase 2 study to determine the efficacy and safety of the combination of the nucleotide polymerase inhibitor sofosbuvir, the NS5A inhibitor velpatasvir, and the NS3/4A protease inhibitor GS-9857 in these patients. METHODS: We performed a multicenter, open-label trial at 32 sites in the United States and 2 sites in New Zealand from March 3, 2015 to April 27, 2015. Our study included 128 treatment-naïve and treatment-experienced patients (1 with HCV genotype 1b; 33 with HCV genotype 2; 74 with HCV genotype 3; 17 with genotype HCV 4; and 3 with HCV genotype 6), with or without compensated cirrhosis. All patients received sofosbuvir-velpatasvir (400 mg/100 mg fixed-dose combination tablet) and GS-9857 (100 mg) once daily for 6-12 weeks. The primary end point was sustained virologic response 12 weeks after treatment (SVR12). RESULTS: After 6 weeks of treatment, SVR12s were achieved by 88% of treatment-naïve patients without cirrhosis (29 of 33; 95% confidence interval, 72%-97%). After 8 weeks of treatment, SVR12s were achieved by 93% of treatment-naïve patients with cirrhosis (28 of 30; 95% CI, 78%-99%). After 12 weeks of treatment, SVR12s were achieved by all treatment-experienced patients without cirrhosis (36 of 36; 95% CI, 90%-100%) and 97% of treatment-experienced patients with cirrhosis (28 of 29; 95% CI, 82%-100%). The most common adverse events were headache, diarrhea, fatigue, and nausea. Three patients (1%) discontinued treatment due to adverse events. CONCLUSIONS: In a phase 2 open-label trial, we found sofosbuvir-velpatasvir plus GS-9857 (8 weeks in treatment-naïve patients or 12 weeks in treatment-experienced patients) to be safe and effective for patients with HCV genotype 2, 3, 4, or 6 infections, with or without compensated cirrhosis.

RESUMO

OBJECTIVE: We compared survival outcomes in 313 patients with unresectable hepatocellular carcinoma (HCC) treated with two different transcatheter arterial chemoembolization (TACE) regimens: triple-drug TACE or single-drug TACE using drug-eluting beads. MATERIALS AND METHODS: In this retrospective study, patient selection criteria were uniform. The triple-drug group (n = 166) underwent TACE using ethiodized oil with doxorubicin, cisplatin, and mitomycin-C with a microsphere embolic. The single-drug group (n = 147) underwent TACE using doxorubicin-eluting beads. Group characteristics were classified and analyzed, and survival was calculated using standard statistical methods. All patients were followed until death. Those undergoing orthotopic liver transplant (OLT) were also followed. RESULTS: There were no significant differences between the two groups in terms of demographics, Child-Pugh class, or Okuda stage. With patients undergoing OLT censored (n = 73), the mean (± standard error) survival in the triple-drug group was 23.49 ± 2.38 months, and the median survival was 16.00 ± 1.51 months. Mean survival in the single-drug bead group was 28.16 ± 2.75 months, and the median survival was 15.00 ± 1.50 months (p = 0.168). With patients undergoing OLT censored, the mean and median survival for the total cohort were 26.25 ± 1.97 and 15.00 ± 1.08 months, respectively. In the entire cohort that did not undergo OLT, patients with Child-Pugh class A disease survived significantly longer than did patients with Child-Pugh class B disease. Elevated α-fetoprotein levels were associated with shorter survival, and patients undergoing TACE with drug-eluting beads had shorter hospital stays. Although a greater percentage annual survival was observed in patients undergoing drug-eluting bead TACE who had Child-Pugh class A, Okuda stage I, and Barcelona Clinic Liver Cancer classes A and B disease starting at 36 months, this suggested survival advantage did not reach statistical significance. CONCLUSION: We found no significant survival difference in patients with unresectable HCC treated with triple-drug TACE compared with single-drug TACE using doxorubicin-eluting beads.

RESUMO

Prevention of hepatitis B virus (HBV) transmission from infected mothers to their newborns is critical to HBV control and eventual eradication. Mother-to-child perinatal transmission causes the highest chronic carrier rate (>85%) with a high rate of subsequent chronic liver disease and hepatocellular carcinoma. This risk is reduced by 90% with HBV vaccine given along with hepatitis B immune globulin (HBIG) starting at birth. New analyses of our data from US trials of HBIG and HBV vaccine in high-risk infants revealed better efficacy with yeast-recombinant vaccine than plasma-derived vaccine, especially in preventing late onset infections, with evidence that vaccine prevented transmission of maternal HBV infection with the glycine to arginine mutation in surface antigen codon 145 (sG145R). Most late infections with sG145R were in vaccine non-responders, suggesting escape from HBIG rather than from vaccine-induced antibody. Our findings also help explain survey results from Taiwan following universal childhood immunization implemented in the mid-1980s. We conclude that current vaccines will remain effective against surface antigen mutants. Anti-viral drugs in high-risk pregnant women, in combination with newborn HBIG and vaccine, show promise for eliminating residual breakthrough neonatal infections, critical to meeting WHO 2030 goals and for eradicating HBV.

RESUMO

OBJECTIVES: Data from the United States are lacking regarding the impact of entecavir (ETV) on the risk of hepatocellular carcinoma (HCC). Our aim is to determine whether treatment with ETV is associated with a reduced HCC risk by calculating the expected HCC incidence based on the Risk Estimation for Hepatocellular Carcinoma in Chronic Hepatitis B (REACH-B) model and comparing it with the observed HCC incidence. METHODS: The incidence of HCC in US patients treated with ETV between 2005 and 2013 in a retrospective cohort was obtained. The predicted HCC incidence was calculated using the REACH-B model. The standardized incidence ratios (SIRs) were calculated as a ratio of observed over predicted HCC cases. RESULTS: Of 841 patients, 646 (65% male, 84% Asian, median age 47 years, 36% hepatitis B e antigen positive, 9.4% with cirrhosis) met the inclusion criteria. Over a median follow-up of 4 years, 17 (2.6%) cases of HCC were diagnosed, including 8 out of 61 (13.1%) patients with cirrhosis and 9 out of 585 (1.5%) without cirrhosis. Compared with those without HCC, the 17 patients with HCC were older at 53 years vs. 47 years and more likely to have cirrhosis at 47.1% vs. 8.4%. Among patients without cirrhosis, the observed HCC incidence was significantly lower than predicted by the fourth year (SIR, 0.37; 95% confidence interval: 0.166-0.82). A sensitivity analysis that comprised all patients, including those with cirrhosis, showed that at the maximum follow-up time of 8.2 years, a significantly lower than predicted HCC incidence was noted with an SIR of 0.56 (95% confidence interval: 0.35-0.905). CONCLUSIONS: Based on the REACH-B model, long-term ETV therapy was associated with a lower than predicted HCC incidence. However, the risk of HCC persisted, and careful HCC surveillance remains warranted despite the anti-viral treatment.

RESUMO

BACKGROUND: Hepatic encephalopathy (HE) is a major complication of cirrhosis and is associated with decreased survival and increased health care utilization. AIM: The aim of this study was to evaluate the efficacy of probiotics in the management minimal hepatic encephalopathy HE (MHE) and overt HE (OHE) in comparison to no treatment/placebo and lactulose. METHODS: The main outcomes measured were mortality, improvement in MHE, progression to OHE in patients with MHE and hospitalization. We calculated odds ratios (OR) with 95% confidence intervals (CI). Study heterogeneity was assessed using the I(2) statistic. RESULTS: Fourteen studies totalling 1152 patients were included in the analysis. The use of probiotics had no impact on the overall mortality when compared to either lactulose (OR: 1.07, 95% CI: 0.47-2.44, P = 0.88) or no treatment/placebo (OR: 0.69, 95% CI: 0.42-1.14, P = 0.15). When probiotics was compared to no treatment/placebo, it was associated with a significant improvement in MHE (OR: 3.91, 95% CI: 2.25-6.80, P < 0.00001), decreased hospitalization rates (OR: 0.53, 95% CI: 0.33-0.86, P = 0.01) and decreased progression to overt hepatic encephalopathy (OR: 0.40, 95% CI: 0.26-0.60, P < 0.0001). However when compared to lactulose, probiotics did not show a significant difference in improvement of MHE (OR: 0.81, 95% CI: 0.52-1.27, P = 0.35), hospitalization rates (OR: 1.02, 95% CI: 0.52-1.99, P = 0.96) or progression to overt hepatic encephalopathy (OR: 1.24, 95% CI 0.73-2.10, P = 0.42). CONCLUSIONS: Overall the use of probiotics was more effective in decreasing hospitalization rates, improving MHE and preventing progression to OHE in patients with underlying MHE than placebo, but similar to that seen with lactulose. The use of probiotics did not affect mortality rates.

RESUMO

BACKGROUND: Effective, pangenotypic treatments for hepatitis C virus (HCV) infection are needed. OBJECTIVE: To assess the safety and efficacy of sofosbuvir with velpatasvir in patients infected with HCV genotypes 1 to 6. DESIGN: Randomized, phase 2, open-label study. (ClinicalTrials.gov: NCT01858766). SETTING: 48 U.S. sites. PATIENTS: 377 treatment-naive noncirrhotic patients. In part A, patients infected with HCV genotypes 1 to 6 were randomly assigned to sofosbuvir, 400 mg, with velpatasvir, 25 or 100 mg, for 12 weeks. In part B, patients with genotype 1 or 2 HCV infection were randomly assigned to sofosbuvir, 400 mg, and velpatasvir, 25 or 100 mg, with or without ribavirin for 8 weeks. MEASUREMENTS: Sustained virologic response at 12 weeks (SVR12). RESULTS: In part A, SVR12 rates were 96% (26 of 27) with velpatasvir, 25 mg, and 100% (28 of 28) with velpatasvir, 100 mg, for genotype 1; 93% (25 of 27) in both groups for genotype 3; and 96% (22 of 23) with velpatasvir, 25 mg, and 95% (21 of 22) with velpatasvir, 100 mg, for genotypes 2, 4, 5, and 6. In part B, for genotype 1, SVR12 rates were 87% (26 of 30) with velpatasvir, 25 mg; 83% (25 of 30) with velpatasvir, 25 mg, plus ribavirin; 90% (26 of 29) with velpatasvir, 100 mg; and 81% (25 of 31) with velpatasvir, 100 mg, plus ribavirin. For genotype 2, SVR12 rates were 77% (20 of 26) with velpatasvir, 25 mg; 88% (22 of 25) with velpatasvir, 25 mg, plus ribavirin; 88% (23 of 26) with velpatasvir, 100 mg; and 88% (23 of 26) with velpatasvir, 100 mg, plus ribavirin. Adverse events included fatigue (21%), headache (20%), and nausea (12%). One patient committed suicide. LIMITATION: The study was open-label, no inferential statistics were planned, and sample sizes were small. CONCLUSION: Twelve weeks of sofosbuvir, 400 mg, and velpatasvir, 100 mg, was well-tolerated and resulted in high SVR in patients infected with HCV genotypes 1 to 6.

RESUMO

BACKGROUND & AIMS: It is controversial if obesity has an impact on overall survival after liver transplantation (LT). The goal of this study was to determine if obesity impacts liver transplant recipient survival. Through subgroup analysis, we also evaluated different body mass index (BMI) thresholds and the confounding effect of ascites on survival. METHODS: A systematic literature search from 1990 until July 2013. The main outcome was to evaluate the impact of obesity on survival in adult LT recipients. Dochotomous outcomes were reported as relative risk (RR) with 95% confidence intervals (CI). RESULTS: Thirteen studies with a total 2275 obese and 72 212 non obese patients were included in the analysis. The combined analysis showed no difference in mortality between control and increased weight patients (RR = 0.97, 95% CI [0.82, 1.13], P = 0.66) at last follow-up. Moreover, no differences in mortality were noted in subgroup analysis comparing different BMI thresholds. There was also no differences in survival when BMI was adjusted for ascites or in studies where the liver disease severity was similar. Obese patients had worse survival than nonobese patients in pooled analysis of studies which had similar causes of liver disease (RR = 0.69, 95% CI [0.52, 0.92], P = 0.01). CONCLUSION: The results of our pools analysis suggest that BMI does not specifically impact patient survival. However, obese patients have worse survival when analysis was performed in studies whose cohorts of obese and nonobese patients had similar causes of liver disease.

RESUMO

BACKGROUND: Fibrosing cholestatic hepatitis (FCH) is an uncommon but potentially fatal complication of recurrent hepatitis C (HCV) in liver transplant recipients. METHODS: We matched the treatment outcomes of 10 liver transplant recipients who developed FCH with those of 10 recipients with recurrent HCV without FCH treated with sofosbuvir and ribavirin. RESULTS: Baseline mean alanine transaminase, aspartate transaminase, alkaline phosphatase, and total bilirubin were 186 U/L, 197 U/L, 243 U/L, and 6.7 mg/dL, respectively, in the FCH recipients and 82 U/L, 60 U/L, 110 U/L, and 0.99 mg/dL, respectively, in non-FCH recipients. The sustained viral response in FCH and non-FCH recipients was 40% and 80%, respectively. One-yr patient and graft survival rates were 90% and 80%, respectively, in FCH recipients, and 100% in non-FCH recipients. Seven FCH and six non-FCH recipients were treated for anemia with blood transfusion and/or erythropoietin growth factors. CONCLUSION: Our results suggest that the use of sofosbuvir and ribavirin is effective and tolerable in liver transplant recipients treated for recurrent FCH. There is a trend of lower sustained viral response, patient survival, and graft survival in the FCH recipients.

RESUMO

INTRODUCTION: Loss of HBeAg and development of anti-HBe (seroconversion) is seen as a milestone and endpoint in the treatment of HBeAg-positive patients with chronic hepatitis B (CHB). Among patients treated with nucleos(t)ide analogs (NA), recurrent viremia is common after discontinuation of therapy. Entecavir (ETV) and tenofovir (TDF) are highly potent NA. The durability of virological response and HBeAg seroconversion in patients treated with these agents is not well studied. METHODS: We retrospectively studied the outcomes of 54 HBeAg-positive CHB patients who were treated with either ETV (n = 30) or TDF (23) or both (n = 1) that achieved virological response and underwent seroconversion and consolidation therapy before cessation of treatment. RESULTS: Only 4 (7%) patients had sustained virological, serological, and biochemical remission. Thirteen patients (24%) continued to have HBV DNA levels below 2000 IU/mL and normal alanine aminotransferase activity (ALT). Thirty-seven patients (69%) developed HBV DNA >2000 IU/mL, with 20 having elevated ALT. Among these 37 patients, 23 (62%) remained HBeAg negative/anti-HBe positive, 12 (32%) became HBeAg positive, and 2 (5%) were HBeAg and anti-HBe negative. Duration of consolidation therapy did not correlate with low versus high level of virological relapse. CONCLUSIONS: Durability of HBeAg seroconversion associated with ETV or TDF was not superior to that reported in patients treated with less potent NA. Our results, aggregated with others, suggest HBeAg seroconversion should not be considered as a treatment endpoint for most HBeAg-positive patients treated with NA. Future updates of treatment guidelines should reconsider HBeAg seroconversion as an endpoint to therapy.

RESUMO

Coffee is one of the most commonly consumed beverages in the world. Its health benefits including improved overall survival have been demonstrated in a variety of disease states. To examine the association of coffee consumption with liver disease, a systematic review of studies on the effects of coffee on liver associated laboratory tests, viral hepatitis, nonalcoholic fatty liver disease (NAFLD), cirrhosis and hepatocellular carcinoma (HCC) was performed. Coffee consumption was associated with improved serum gamma glutamyltransferase, aspartate aminotransferase and alanine aminotransferase values in a dose dependent manner in individuals at risk for liver disease. In chronic liver disease patients who consume coffee, a decreased risk of progression to cirrhosis, a lowered mortality rate in cirrhosis patients, and a lowered rate of HCC development were observed. In chronic hepatitis C patients, coffee was associated with improved virologic responses to antiviral therapy. Moreover, coffee consumption was inversely related to the severity of steatohepatitis in patients with non-alcoholic fatty liver disease. Therefore, in patients with chronic liver disease, daily coffee consumption should be encouraged.

RESUMO

BACKGROUND AND AIM: The performance of alpha-fetoprotein (AFP) in the detection of hepatocellular carcinoma (HCC) recurrence after radiofrequency ablation was analyzed. METHODS: One hundred and forty-six solitary HCC lesions treated by radiofrequency ablation were evaluated. Using the AFP cutoff level at ≥ 20 ng/mL, tumors were categorized into AFP or non-AFP-producing HCC. Factors associated with true and false interpretations for cancer recurrence including analysis of elevated alanine aminotransferase (ALT) were evaluated. The performance of AFP using different cutoff levels adjusted for abnormal ALT was compared. RESULTS: Of 146 HCCs, 103 demonstrated no HCC recurrence while 43 had local recurrence. In non-recurrence HCC cases, increased AFP levels (false positive) were associated with concomitant ALT elevations, while those with normal AFP (true negative) had correspondingly normal ALT values (P < 0.001). The AFP false positive rate in cases of elevated ALT was significantly higher than those with normal ALT levels (31.9% vs 5.4%, P = 0.001). Among all positive AFP tests, those with false positive values (non-recurrence) had a significantly lower AFP level than the true positive (recurrence) HCC cases (39.8 ng/mL vs 372 ng/mL, P < 0.001). At the 20 ng/mL cutoff level, the sensitivities of AFP for detecting recurrence in non-AFP-producing HCC and AFP-producing HCC were 12.0%, and 72.2%, respectively. Using a modified AFP criteria of ≥ 100 ng/mL for cases where ALT ≥ 40 U/L, the sensitivity and specificity in AFP-producing tumors increased from 72.2% and 56% to 100% and 85%, respectively. CONCLUSION: Serum AFP is a useful test in the detection of HCC recurrence in AFP-producing HCC. The performance in AFP-producing HCC was significantly improved after adjusting for elevation of serum ALT.

RESUMO

The aim of this study was to determine the prognostic value of complete tumor encapsulation as visualized on magnetic resonance imaging (MRI) in patients with a solitary large hepatocellular carcinoma (HCC) beyond the Milan criteria for liver transplantation (LT). Between December 2000 and March 2011, 57 patients who had a solitary HCC exceeding 5 cm in diameter at the time of initial MRI before any treatment were identified. MRI images of the patients were independently reviewed by 2 experienced readers for the presence of complete tumoral encapsulation. The medical records of the patients were reviewed for an outcome analysis. Thirty of the 57 patients had completely encapsulated HCC according to MRI. There was excellent interobserver agreement between the 2 readers for the assessment of complete encapsulation (κ=0.86). Overall survival was significantly longer for patients with completely encapsulated HCC versus patients with incompletely or nonencapsulated tumors (P<0.001), and this included a subanalysis of 33 patients who received locoregional treatment (LRT; P=0.04). The presence of complete encapsulation was a strong predictor for survival in these patients according to both univariate [hazard ratio (HR)=0.24, 95% confidence interval (CI)=0.12-0.52, P<0.001] and multivariate analyses (HR=0.25, 95% CI=0.07-0.85, P=0.03). The rates of down-staging (P<0.001) and eventual LT (P=0.02) after LRT were also significantly higher in the patients with completely encapsulated tumors. In conclusion, complete tumor encapsulation on MRI is a potentially useful predictor for favorable biology in patients with a solitary large HCC. This new imaging biomarker may have a role in treatment selection for patients whose tumors exceed the Milan criteria size limits.

RESUMO

Importance: Hepatocellular carcinoma (HCC) and its mortality are on the rise. Viral hepatitis and alcohol are leading risk factors; however, other risk factors among veterans are less defined, including Agent Orange (AO), an herbicide linked to several cancers. Objective: To assess the association of AO exposure and HCC in a national cohort of Vietnam veterans. Design, Setting, and Participants: This retrospective cohort study included Vietnam veterans who served between 1966 and 1975, were male, were older than 18 years at the time of deployment, and had established follow-up in the Veterans Affairs (VA) between 2000 and 2019. Veterans with AO exposure were identified in the disability data via validated clinical surveys. Relevant clinical risk factors for cirrhosis and HCC were collected. Patients were stratified based on cirrhosis status, as defined by consecutive diagnosis found by documented International Classification of Diseases, Ninth Revision and International Statistical Classification of Diseases and Related Health Problems, Tenth Revision scores or calculated Fibrosis-4 scores. Data were collected from January 1, 2019, to December 31, 2020, and analyzed from December 2020 to October 2023. Main Outcome and Measures: Incident HCC was the primary outcome. AO and HCC association was estimated using a multivariable Cox regression analysis, with death and liver transplant as competing events. Results: Of the 296 505 eligible veterans (222 545 [75.1%] White individuals and 44 342 [15.0%] Black individuals), 170 090 (57%) had AO exposure (mean [SD] age, 21.62 [3.49] years; 131 552 White individuals [83.2%] and 22 767 Black individuals [14.4%]) and 35 877 (12.1%) had cirrhosis. Veterans who were not exposed to AO were more likely to smoke (109 689 of 126 413 [86.8%] vs 146 061 of 170 090 [85.9%]); use alcohol (54 147 of 126 413 [42.8%] vs 71 951 of 170 090 [42.3%]) and have viral hepatitis (47 722 of 126 413 [37.8%] vs 58 942 of 170 090 [34.7%]). In a multivariable competing risk model, AO exposure was not associated with HCC. Among veterans with cirrhosis, self-identification as Hispanic individuals (aHR, 1.51; 95% CI, 1.30-1.75; P <.001) or Black individuals (aHR, 1.18; 95% CI, 1.05-1.32; P = .004), and having a diagnosis of viral hepatitis (aHR, 3.71; 95% CI, 3.26-4.24; P <.001), alcohol-associated liver disease (aHR, 1.32; 95% CI, 1.19-1.46; P <.001), and nonalcoholic fatty liver disease (NAFLD) (aHR, 1.92; 95% CI, 1.72-2.15; P <.001) were associated with HCC. Among veterans without cirrhosis, hypertension (aHR, 1.63; 95% CI, 1.23-2.15; P <.001) and diabetes (aHR, 1.52; 95% CI, 1.13-2.05; P = .005) were also associated with HCC. Early smoking and alcohol use were significant risk factors for HCC. Conclusions and Relevance: In this large nationwide cohort study of Vietnam veterans, AO exposure was not associated with HCC. Smoking, alcohol, viral hepatitis, and NAFLD were the most important clinical risk factors for HCC.
