Recurrent alcohol-associated hepatitis is common and is associated with increased mortality. Hepatology 2024:01515467-990000000-00773. [PMID: 38441908 DOI: 10.1097/hep.0000000000000825] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/14/2023] [Accepted: 02/06/2024] [Indexed: 04/11/2024]
Abstract
BACKGROUND AND AIMS Alcohol relapse after surviving an episode of alcohol-associated hepatitis (AH) is common. However, the clinical features, risk factors, and prognostic implications of recurrent alcohol-associated hepatitis (RAH) are not well described. APPROACH AND RESULTS A registry-based study was done of patients admitted to 28 Spanish hospitals for an episode of AH between 2014 and 2021. Baseline demographics and laboratory variables were collected. Risk factors for RAH were investigated using Cox regression analysis. We analyzed the severity of the index episodes of AH and compared it to that of RAH. Long-term survival was assessed by Kaplan-Meier curves and log-rank tests. A total of 1118 patients were included in the analysis, 125 (11%) of whom developed RAH during follow-up (median: 17 [7-36] months). The incidence of RAH in patients resuming alcohol use was 22%. The median time to recurrence was 14 (8-29) months. Patients with RAH had more psychiatric comorbidities. Risk factors for developing RAH included age <50 years, alcohol use >10 U/d, and history of liver decompensation. RAH was clinically more severe compared to the first AH (higher MELD, more frequent ACLF, and HE). Moreover, alcohol abstinence during follow-up was less common after RAH (18% vs. 45%, p <0.001). Most importantly, long-term mortality was higher in patients who developed RAH (39% vs. 21%, p = 0.026), and presenting with RAH independently predicted high mortality (HR: 1.55 [1.11-2.18]). CONCLUSIONS RAH is common and has a more aggressive clinical course, including increased mortality. Patients surviving an episode of AH should undergo intense alcohol use disorder therapy to prevent RAH.

Poor Outcomes of Patients With NAFLD and Moderate Renal Dysfunction or Short-Term Dialysis Receiving a Liver Transplant Alone. Transpl Int 2022; 35:10443. [PMID: 36568138 PMCID: PMC9784907 DOI: 10.3389/ti.2022.10443] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2022] [Accepted: 10/27/2022] [Indexed: 12/13/2022]
Abstract
The outcomes of patients with moderate renal impairment and the impact of liver disease etiology on renal function recovery after liver transplant alone (LTA) are largely unknown. We explored whether NAFLD patients with pre-LTA moderate renal dysfunction (GFR 25-45 ml/min/1.73 m2) may be more susceptible to develop post-LTA severe renal dysfunction (GFR<15 ml/min/1.73 m2) than ALD patients, as well as other overall outcomes. Using the UNOS/OPTN database, we selected patients undergoing liver transplant for NAFLD or ALD (2006-2016), 15,103 of whom received LTA. NAFLD patients with moderate renal dysfunction were more likely to develop subsequent GFR<15 ml/min/1.73 m2 than ALD patients (11.1% vs. 7.38%, p < 0.001). Patients on short-term dialysis pre-LTA (≤12 weeks) were more likely to develop severe renal dysfunction (31.7% vs. 18.1%), especially in NAFLD patients, and were more likely to receive a further kidney transplant (15.3% vs. 3.7%) and had lower survival (48.6% vs. 50.4%) after LTA (p < 0.001 for all). NAFLD was an independent risk factor for post-LTA severe renal dysfunction (HR = 1.2, p = 0.02). NAFLD patients with moderate renal dysfunction and those receiving short-term dialysis prior to LTA are at a higher risk of developing subsequent severe renal dysfunction. Underlying etiology of liver disease may play a role in predicting development and progression of renal failure in patients receiving LTA.

The MELD Score Is Superior to the Maddrey Discriminant Function Score to Predict Short-Term Mortality in Alcohol-Associated Hepatitis: A Global Study. Am J Gastroenterol 2022; 117:301-310. [PMID: 34962498 PMCID: PMC8999152 DOI: 10.14309/ajg.0000000000001596] [Citation(s) in RCA: 30] [Impact Index Per Article: 15.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/06/2021] [Accepted: 10/27/2021] [Indexed: 02/03/2023]
Abstract
INTRODUCTION Several scoring systems predict mortality in alcohol-associated hepatitis (AH), including the Maddrey discriminant function (mDF) and model for end-stage liver disease (MELD) score developed in the United States, Glasgow alcoholic hepatitis score in the United Kingdom, and age, bilirubin, international normalized ratio, and creatinine score in Spain. To date, no global studies have examined the utility of these scores, nor has the MELD-sodium been evaluated for outcome prediction in AH. In this study, we assessed the accuracy of different scores to predict short-term mortality in AH and investigated additional factors to improve mortality prediction. METHODS Patients admitted to hospital with a definite or probable AH were recruited by 85 tertiary centers in 11 countries and across 3 continents. Baseline demographic and laboratory variables were obtained. The primary outcome was all-cause mortality at 28 and 90 days. RESULTS In total, 3,101 patients were eligible for inclusion. After exclusions (n = 520), 2,581 patients were enrolled (74.4% male, median age 48 years, interquartile range 40.9-55.0 years). The median MELD score was 23.5 (interquartile range 20.5-27.8). Mortality at 28 and 90 days was 20% and 30.9%, respectively. The area under the receiver operating characteristic curve for 28-day mortality ranged from 0.776 for MELD-sodium to 0.701 for mDF, and for 90-day mortality, it ranged from 0.773 for MELD to 0.709 for mDF. The area under the receiver operating characteristic curve for mDF to predict death was significantly lower than all other scores. Age added to MELD obtained only a small improvement of AUC. DISCUSSION These results suggest that the mDF score should no longer be used to assess AH's prognosis. The MELD score has the best performance in predicting short-term mortality.

Non-malignant portal vein thrombosis in a cohort of cirrhotic patients: Incidence and risk factors. Hepatol Res 2021; 51:1064-1072. [PMID: 34324766 DOI: 10.1111/hepr.13703] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/10/2021] [Revised: 07/06/2021] [Accepted: 07/21/2021] [Indexed: 01/04/2023]
Abstract
AIM Non-malignant portal vein thrombosis (PVT) is a complication of liver cirrhosis. The aim of this study was to evaluate the annual incidence of PVT and related risk factors. METHODS We retrospectively reviewed clinical, laboratory, and radiological data collected prospectively from September 2016 to September 2017. A follow-up of 36 months was performed in a subset of patients to determine the cumulative incidence of PVT and related complications. RESULTS The study included 567 patients. The incidence of PVT at 12, 24, and 36 months was 3.7%, 0.8%, and 1.4%, respectively. Patients with PVT were compared with patients without PVT, and showed differences in albumin (p = 0.04), aspartate aminotransferase (p = 0.04), hemoglobin (p = 0.01), and prothrombin activity (p = 0.01). The presence of hydropic decompensation (57.1% vs. 30.1%; p 0.004), gastroesophageal varices (76.2% vs. 39.5%; p = 0.05), variceal bleeding (52.4% vs. 22.7%; p < 0.001), hepatic encephalopathy (38.1% vs. 9.9%; p = 0.01), spontaneous bacterial peritonitis (9.5% vs. 1.7%; p < 0.001), and use of beta-blockers (71.4% vs. 27.7%; p < 0.001) were significantly associated. In the multivariate analysis, use of beta-blockers and hepatic encephalopathy appeared as risk factors, and high albumin levels a protective factor. CONCLUSIONS The incidence of PVT was 3.7%. Beta-blockers and hepatic encephalopathy were risks factors. High albumin levels were a protective factor.

Abstract
Background: Central obesity, due to the accumulation of visceral fat(VF), is one of the main risk factors for venous thrombosis. The aim of this study was to determine if VF may be a risk factor for development of portal vein thrombosis(PVT) in cirrhotic patients.Methods: A total of 214 cirrhotic patients at the outpatient clinic were consecutively included, undergoing an anthropometric evaluation, blood tests and bioimpedance.Results: Median MELDscore was10. Prior liver decompensation occurred in 44.9% of patients and 35.6% of patients had large esophageal varices. Mean body mass index was 28.7 Kg/m2 (39.3%were obese) and mean waist circumference(WC) was 103.8 cm. A 7.5% of patients had PVT at the time of inclusion. PVT was more frequent in males(93.8 vs. 68.2%, p = 0.03). Patients with PVT had a higher WC(111.9 vs. 103.2 cm, p = 0.02) and VF (17.1 vs. 14.5, p = 0.04). PVT was also more frequent in patients with prior decompensation (81.3 vs. 41.9%, p < 0.01) and with large esophageal varices(62.5 vs. 33.3%, p = 0.02). In the simplified multivariate analysis, PVT was independently associated with the presence of portal hypertension(OR 13, 95%CI 1.6-108.3, p = 0.02) and VF(OR 1.2, 95%CI 1.03-1.3, p = 0.01).Conclusion: VF was independently associated with PVT in cirrhotic patients. VF may be more reliable than conventional anthropometric measurements for cirrhotic patients.

Abstract
INTRODUCTION AND AIMS To determine the prevalence of minimal hepatic encephalopathy (MHE) in patients with liver cirrhosis (LC) due to hepatitis C virus (HCV) infection and to evaluate the impact of sustained viral response (SVR) on MHE. MATERIAL AND METHODS We performed a prospective study using MHE screening and follow-up on patients with HCV and LC. The patients were evaluated at the beginning of treatment and 24 weeks after treatment. RESULTS 64 patients were included. 51.6% were male, the median age was 62years, Child-Pugh classification A/B/C 93.8%/4.7%/1.6% and median MELD was 8.3. Prior hydropic decompensation was present in 11 patients. Median values of liver stiffness, as measured by transient elastography (TE) were 22.8 KPa. Indirect signs of portal hypertension (PH) were present in 53.1% of patients, with a mean of 11.9 mmHg among the ones with a measurement of the hepatic venous pressure gradient. The prevalence of MHE before treatment was 26.6%. After treatment, 98.4% of patients achieved SVR. The presence of MHE at 24weeks post-treatment had an statistically significant association with the presence of pre-treatment MHE (80% vs. 21.6%; p < 0.01), higher MELD scores at 24-weeks post-treatment (9.8 vs. 8; p = 0.02), higher Child-Pugh scores at 24-weeks post-treatment (p = 0.04), higher baseline INR levels (1.4 vs. 1.1; p < 0.001) and with the presence of indirect signs of PH (100% vs. 47.1%; p = 0.02). During follow-up, those patients without MHE at 24weeks post-treatment had a higher probability of experiencing an improvement in post-treatment TE (80.9% vs. 40%, p = 0.04). CONCLUSION We found that SVR may lead to MHE resolution in a considerable proportion of patients, which has potential implications for disease prognosis.

Hepatitis C virus plays with fire and yet avoids getting burned. A review for clinicians on processing bodies and stress granules. Liver Int 2018; 38:388-398. [PMID: 28782251 DOI: 10.1111/liv.13541] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/14/2016] [Accepted: 08/02/2017] [Indexed: 02/13/2023]
Abstract
Over the last few years, many reports have defined several types of RNA cell granules composed of proteins and messenger RNA (mRNA) that regulate gene expression on a post-transcriptional level. Processing bodies (P-bodies) and stress granules (SGs) are among the best-known RNA granules, only detectable when they accumulate into very dynamic cytosolic foci. Recently, a tight association has been found between positive-stranded RNA viruses, including hepatitis C virus (HCV), and these granules. The present article offers a comprehensive review on the complex and paradoxical relationship between HCV, P-bodies and SGs from a translational perspective. Despite the fact that components of P-bodies and SGs have assiduously controlled mRNA expression, either by sequestration or degradation, for thousands of years, HCV has learned how to dangerously exploit certain of them for its own benefit in an endless biological war. Thus, HCV has gained the ability to hack ancient host machineries inherited from prokaryotic times. While P-bodies and SGs are crucial to the HCV cycle, in the interferon-free era we still lack detailed knowledge of the mechanisms involved, processes that may underlie the long-term complications of HCV infection.

Validation of noninvasive methods to predict the presence of gastroesophageal varices in a cohort of patients with compensated advanced chronic liver disease. J Gastroenterol Hepatol 2017; 32:1867-1872.

Abstract
BACKGROUND AND AIM The aim was to validate noninvasive methods to predict the presence of gastroesophageal varices (GEV) in patients with suspected compensated advanced chronic liver disease. METHODS We retrospectively reviewed clinical and radiological data collected prospectively between September 2013 and September 2015. We reviewed 442 consecutive patients with suspected compensated advanced chronic liver disease measured by transient elastography (TE) and a gastroscopy. We evaluated platelets, spleen diameter, TE, liver stiffness × spleen size/platelets (LSPS), variceal risk index (VRI), Baveno VI strategy, and Augustin algorithm. RESULTS One hundred sixty-one out of 442 patients were included. Patients with GEV were compared with patients without GEV and showed statistically significant differences in platelet count (117 SD 51 vs 149 SD 62; P = 0.02), spleen diameter (13.0 SD 1.9 vs 11.5 SD 2; P = 0.003), and TE (28 SD 15 vs 19 SD 10; P = 0.001). Single methods (platelet count and TE) diagnosed correctly 51% and 71.4% of patients. Combined methods (LSPS, VRI, Baveno VI, and Augustin algorithm) diagnosed correctly 78%, 83.6%, 45.3%, and 57.1% of patients. Patients with GEV misdiagnosed: platelets 5/161 (3.1%), TE 6/161 (3.7%), LSPS 16/159 (10%), VRI 18/159 (11.3%), Baveno VI 3/161 (1.8%), and Augustin algorithm 6/161 (3.7%). Rate of unnecessary gastroscopies: platelets 46%, TE 25%, LSPS 13%, VRI 6%, Baveno VI 53%, and Augustin algorithm 39.1%. CONCLUSIONS A significant number of patients were classified correctly using TE, LSPS, and VRI; however, LSPS and VRI had unacceptable rates of misdiagnoses. TE is the best noninvasive single method and the Baveno VI strategy the best combined method.

Permissiveness of human hepatocellular carcinoma cell lines for hepatitis C virus entry and replication. Virus Res 2017; 240:35-46. [PMID: 28751105 DOI: 10.1016/j.virusres.2017.07.018] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2017] [Revised: 07/20/2017] [Accepted: 07/20/2017] [Indexed: 12/28/2022]
Abstract
Hepatitis C virus (HCV) is a globally prevalent pathogen and is associated with high death rates and morbidity. Since its discovery in 1989, HCV research has been impeded by the lack of a robust infectious cell culture system and thus in vitro studies on diverse genetic backgrounds are hampered because of the limited number of hepatoma cell lines which are able to support different aspects of the HCV life cycle. In the current study, we sought to expand the limited number of permissive cells capable of supporting the diverse phases of the HCV life cycle. Initially, we screened a panel of new hepatoma-derived cell lines, designated BCLC-1, -2, -3, -4, -5, -6, -9 and -10 cells, for their ability to express essential HCV receptors and subsequently to support HCV entry by using the well-characterized HCV pseudoparticle system (HCVpp). Apart from BCLC-9, all BCLC cell lines were permissive for HCVpp infection. Next, BCLC cells were subjected to short- and long-term HCV RNA replication studies using HCV subgenomic replicons. Interestingly, only BCLC-1, -5 and -9 cells, supported short-term HCV RNA replication, but the latter were excluded from further studies since they were refractory for HCV entry. BCLC-1, -5 were able to support long-term HCV replication too; yet BCLC-5 cells supported the highest long-term HCV RNA replication levels. Furthermore, cured BCLC-5 clones from HCV subgenomic replicon, showed increased permissiveness for HCV RNA replication. Strikingly, we were unable to detect endogenous BCLC-5 miR122 expression - an important HCV host factor- and as expected, the exogenous expression of miR122 in BCLC-5 cells increased their permissiveness for HCV RNA replication. However, this cell line was unable to produce HCV infectious particles despite ectopic expression of apolipoprotein E, which in other hepatoma cell lines has been shown to be sufficient to enable the HCV secretion process, suggesting a lack of other host cellular factor(s) and/or the presence of inhibitory factor(s). In conclusion, the establishment of these new permissive cell lines for HCV entry and replication, which possess a different genetic background compared to the well-established models, expands the current repertoire of hepatoma cell lines susceptible to the study of the HCV life cycle and also will aid to further elucidate the cellular determinants that modulate HCV replication, assembly and egress.

Reactivation of Herpesvirus in Patients With Hepatitis C Treated With Direct-Acting Antiviral Agents. Clin Gastroenterol Hepatol 2016; 14:1662-1666.e1. [PMID: 27211502 DOI: 10.1016/j.cgh.2016.05.016] [Citation(s) in RCA: 32] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/23/2016] [Revised: 05/10/2016] [Accepted: 05/10/2016] [Indexed: 02/07/2023]
Abstract
We performed a case-series analysis of reactivation of herpesvirus in patients with hepatitis C virus (HCV) infection treated with direct-acting antiviral (DAA) agents. We collected data from 576 patients with HCV infection treated with DAA combinations at 3 hospitals in Spain, from November 2014 through November 2015. We also collected data from a control population (230 HCV-infected patients, matched for sex and age; 23 untreated and 213 treated with interferon-based regimens). Herpesvirus was reactivated in 10 patients who received DAA therapy (7 patients had cirrhosis and 3 patients had received liver transplants), a median of 8 weeks after the therapy was initiated. None of the controls had herpesvirus reactivation. Patients with herpesvirus reactivation were receiving the DAA agents sofosbuvir with ledipasvir (with or without ribavirin, 7/10), ombitasvir with paritaprevir and ritonavir plus dasabuvir (with or without ribavirin, 2/10), or sofosbuvir with simeprevir plus ribavirin (1/10). Two of the 10 patients developed postherpetic neuralgia and 1 patient developed kerato-uveitis. All 10 patients with herpesvirus reactivation achieved a sustained virologic response. Immune changes that follow clearance of HCV might lead to reactivation of other viruses, such as herpesvirus. Patients with HCV infection suspected of having herpesvirus infection should be treated immediately. Some groups also might be screened for herpesvirus infection.

Hepatitis C virus infection inhibits P-body granule formation in human livers. J Hepatol 2015; 62:785-90.

Abstract
BACKGROUND & AIMS Decoding the myriad of interactions that hepatitis C virus (HCV) establishes with infected cells is mandatory to obtain a complete understanding of HCV biology and its associated pathogenesis. We and others have previously found that HCV infection disrupts the formation of P-bodies in cell culture. These are cytoplasmic RNA granules with key roles in post-transcriptional regulation of gene expression. Therefore, P-body disruption might have consequences beyond viral propagation. However, whether P-body disruption occurs also in vivo is unknown. Aim of this study was to address this important issue. METHODS Formalin-fixed paraffin-embedded liver biopsies from four groups of patients (healthy donors, patients with non-virus related liver inflammation, HCV- and HBV-infected patients) were immunostained to detect DDX6 and Dcp1, two core P-body components. Changes in the localization of these proteins were assessed by confocal microscopy. RESULTS HCV specifically inhibited P-body formation in hepatocytes from human livers regardless of viral genotype, inflammation grade or whether the infection was recent or long established. Importantly, this alteration was reversed once HCV was eliminated by therapy. Furthermore, we observed in vivo an unexpected heterogeneity in P-body composition, which might reflect functional specializations. CONCLUSIONS This is the first comprehensive in vivo P-body analysis that links a pathogenic condition to P-body alterations. Because of their role in gene expression, the alteration of P-bodies should be further studied to understand fully complex HCV-associated pathologies.

IFNL4 polymorphism predicts response to hepatitis C treatment after liver transplantation. J Clin Virol 2014; 61:282-5.

Abstract
BACKGROUND Recent studies in chronic hepatitis C patients have shown that rs368234815 polymorphism nearby IL28B is a better predictor of response to antiviral treatment with pegylated interferon and ribavirin than IL28B polymorphisms (rs12979860 and rs8099917). Its effect could be related to interferon lambda 4 (IFNL4), a protein which seems to confer some paradoxical disadvantages in hepatitis C virus (HCV) immune response. OBJECTIVES To assess the role of IFNL4 rs368234815 polymorphism on the response to antiviral treatment after liver transplantation (LT). STUDY DESIGN IFNL4 and IL28B polymorphisms were genotyped in 86 HCV-infected LT recipients and in their donors; all patients had undergone antiviral treatment with pegylated interferon and ribavirin after LT. RESULTS IFNL4 polymorphism strongly correlated with IL28B ones (p < 0.001). The favorable IFNL4 genotype (TT/TT) was significantly more frequent among donors than recipients (60% donors vs. 22% recipients, p <0.001). Recipient TT/TT genotype was associated with a higher sustained virological response rate after LT (p = 0.024). Nevertheless, the highest sustained virological response frequency was found when both donors and recipients had favorable genotypes (73% vs. 25%, p = 0.002), suggesting a role for donor genotype. CONCLUSIONS Our study demonstrates that IFNL4 rs368234815 polymorphism is an important predictor of response to antiviral treatment in the LT setting. These findings warrant further studies on IFNL4 role in immune response against HCV.

Abstract
Cirrhosis secondary to hepatitis C virus infection is the leading cause of liver transplantation in most countries. Hepatitis C has an accelerated course after transplantation, and for this reason graft and patient survival are decreased in comparison with other indications of liver transplantation. The development of direct-acting antivirals has been a major step in the management of hepatitis C and in a few years from now the infection will be eradicated with the combination of oral drugs with a good safety profile. This will likely allow prevention of hepatitis C recurrence in most cases. Meanwhile, management of hepatitis C virus infection still relies on the combination of interferon, ribavirin and the first-generation protease inhibitors telaprevir and boceprevir.
