Tenofovir versus entecavir on recurrence and mortality of hepatitis B virus-related hepatocellular carcinoma after curative therapy. J Formos Med Assoc 2024:S0929-6646(24)00111-6. [PMID: 38423922 DOI: 10.1016/j.jfma.2024.02.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2023] [Revised: 01/04/2024] [Accepted: 02/20/2024] [Indexed: 03/02/2024] Open
Abstract
BACKGROUND Tenofovir disoproxil fumarate (TDF) and entecavir (ETV) reduce the risk of hepatocellular carcinoma (HCC) in patients of hepatitis B. This study compared the difference between ETV and TDF on risk of HCC recurrence and mortality in patients with HBV-related HCC after curative intent treatment. METHODS Patients with HBV-related HCC who received HCC treatment (surgery or radiofrequency ablation [RFA]) and underwent long-term ETV or TDF therapy were retrospectively included. Baseline characteristics including age, sex, antiviral therapy, liver reserve, HCC stages, pathology reports and treatment modality were obtained. The risk of tumor recurrence, all-cause mortality, HCC-related mortality, and liver function were compared. RESULTS We identified 390 HBV-related HCC patients with curative intent treatment for HCC and treated with ETV (n = 328) or TDF (n = 62) between January 2011 and December 2020. The median age was 60 years, and 90.7% patients were males. After a median follow-up of 29 months, 186 patients developed recurrent HCC and 111 died. The baseline characteristics were comparable except more ALBI grade 3 patients in TDF group (76% vs. 48%, P < 0.001). Compared to ETV group, TDF users had lower all-cause mortality (adjusted hazard ratio [aHR]: 0.38, P = 0.003), and HCC-related mortality (aHR: 0.23, P = 0.005). Lower recurrence rate was noticed in TDF users after inverse probability of treatment weighting (IPTW). TDF users had improved ALBI grade and FIB-4 index compared with ETV groups. CONCLUSIONS TDF therapy is associated with a reduced risk of HCC-related outcomes among patients with HBV-related HCC after curative intent treatment compared with ETV usage.

Abstract
Type III interferon, or interferon lambda (IFNλ), was discovered 20 years ago and has been studied primarily for its role in combatting viral infections. However, it is also induced in response to certain bacterial infections but its roles and effects in this context are relatively poorly understood. In this mini review, we discuss the roles of IFNλ signaling in bacterial infections, highlighting its deleterious or protective effects for different infections. We also discuss a couple of recent studies showing that some bacteria possess defense mechanisms against the effects of IFNλ. We hope that this review will spur further investigation into the roles of IFNλ in the context of bacterial infections and will promote considerations of its therapeutic potential for these infections.

Abstract
INTRODUCTION Hepatitis B virus (HBV) remains a public health concern given its global prevalence and potential complications including hepatocellular carcinoma (HCC). Current therapies, including nucleos(t)ide analogs (NA) and interferons (IFN), are effective in chronic treatment of HBV but rarely provide a functional cure due to inadequate host response and the presence of viral DNA. Therefore, novel therapies that enhance the innate immune response while suppressing DNA transcription may provide definitive treatment of HBV. AREAS COVERED In this review, the authors provide a brief overview of commonly used agents and their efficacy in treatment of HBV. Newer therapies with direct antiviral agents such as bepirovirsen (antisense oligonucleotide (ASO)) and entry inhibitors such as bulevirtide have shown efficacy in reducing viral load but demonstrate further reductions in conjunction with immune modulators such as therapeutic vaccines. EXPERT OPINION Combination therapy is far superior to monotherapy alone, necessitating the need for both immunomodulators and direct antiviral agents in chronic treatment of HBV. Therapies that target covalently closed circular (cccDNA) with immunomodulators like therapeutic vaccines have shown promising results and may ultimately achieve functional cure. However, therapies need to be evaluated in the context of the patient, considering both financial and socioeconomic factors.

Abstract
Hepatitis E is a liver inflammation caused by infection with the hepatitis E virus (HEV). Every year, there are an estimated 20 million HEV infections worldwide, leading to an estimated 3.3 million symptomatic cases of hepatitis E. HEV viral load has been studied about the disease progression; however, hepatic the host gene expression against HEV infection remains unknown. Methods: We identified the expression profiles of hepatic immune response genes in HEV infections. Fresh blood samples were collected from all the study subjects (130 patients and 124 controls) in 3ml EDTA vacutainers. HEV viral load was determined by a real-time PCR. The total RNA was isolated from the blood using the TRIZOL method. The expression of theCCL2, CCL5, CXCL10, CXCL16, TNF, IFNGR1, and SAMSN1 genes was studied in the blood of 130 HEV patients and 124 controls using a real-time PCR. Results: Gene expression profiles indicate high levels of CCL2, CCL5, CXCL10, CXCL16, TNF, IFNGR1, and SAMSN1 genes that might lead to the recruitment of leukocytes and infected cell apoptosis. Conclusion: Our study demonstrated distinct differences in the expression profiles of host immune response-related genes of HEV infections and provided valuable insight into the potential impact of these genes on disease progression.

Changes in serum hepatitis B surface and e antigen, interferon-inducible protein 10, and aminotransferase levels during combination therapy of immune-tolerant chronic hepatitis B. Hepatology 2022; 76:775-787. [PMID: 35188674 DOI: 10.1002/hep.32400] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/06/2021] [Revised: 01/28/2022] [Accepted: 01/30/2022] [Indexed: 12/15/2022]
Abstract
BACKGROUND AND AIMS Treatment of immune-tolerant (IT) children and adults with combined peginterferon alfa-2a and entecavir results in a decline in serum HBeAg and HBsAg concentrations but rarely results in loss of HBeAg or sustained off-treatment response. Factors associated with declines in these viral antigens during treatment remain unexplored. APPROACH AND RESULTS We investigated the pattern of virologic and biochemical response in 86 participants (59 children, 27 adults) by serial quantitative measurement of HBsAg (qHBsAg), quantitative HBeAg (qHBeAg), HBV RNA, interferon-inducible protein (IP-10), IL-18, and alanine aminotransferase (ALT). Each individual had previously been treated with 8 weeks of entecavir followed by 40 weeks of combined peginteferon and entecavir. We defined the interrelationships between these parameters and virologic response measured as nadir declines from baseline for HBeAg and HBsAg. The patterns of HBsAg and HBeAg decline were similar in pediatric and adult participants. Higher levels of IP-10 were observed during treatment in participants with greater ALT elevations and greater reductions of qHBsAg and qHBeAg. Individuals with peak ALT values exceeding three times the upper limit of normal were significantly more likely to have >1 log10 decline in both viral antigens. HBV DNA became undetectable in 21 of 86 (24%) and HBV RNA in 4 of 77 (5%) during therapy, but both markers remained negative only in those who became HBsAg negative, all of whom also had ALT elevations. CONCLUSIONS Induction of IP-10 during peginterferon treatment in adults and children in the IT phase of chronic HBV infection is associated with ALT elevations and decline in viral antigens, suggesting a degree of interferon-inducible viral control.

Abstract
Chronic hepatitis B virus (HBV) infection remains a major health burden worldwide for which there is still no effective curative treatment. Interferon (IFN) consists of a group of cytokines with antiviral activity and immunoregulatory and antitumor effects, that play crucial roles in both innate and adaptive immune responses. IFN-α and its pegylated form have been used for over thirty years to treat chronic hepatitis B (CHB) with advantages of finite treatment duration and sustained virologic response, however, the efficacy is limited and side effects are common. Here, we summarize the status and unique advantages of IFN therapy against CHB, review the mechanisms of IFN-α action and factors affecting IFN response, and discuss the possible improvement of IFN-based therapy and the rationale of combinations with other antiviral agents in seeking an HBV cure.
