No influence of hepatic steatosis on the 3-year outcomes of patients with quiescent chronic hepatitis B

Chronic hepatitis B and metabolic dysfunction-associated steatotic liver disease: Metabolic risk factors are key drivers of hepatocellular carcinoma

Objective

Chronic hepatitis B (CHB) and metabolic dysfunction-associated steatotic liver disease (MASLD) are the leading causes of hepatocellular carcinoma (HCC). This study aimed to explore the impact of baseline MASLD on the risk of HCC development in patients with CHB receiving antiviral treatment.

Methods

We consecutively recruited 535 patients with CHB who initiated antiviral treatment between January 2007 and January 2023. The exclusion criteria included coexisting HDV, HCV, or HIV infection; other chronic liver diseases; extrahepatic malignancies; prior HCC; and HCC development within one year. A baseline liver biopsy was performed in 467 patients (87 %). MASLD was defined as hepatic steatosis diagnosed histologically or by imaging, combined with one cardiometabolic risk factor. The cumulative incidence of HCC and its associated factors was analyzed in patients with CHB, with and without MASLD.

Results

In total, 535 treatment-naïve patients with CHB were included, with a median follow-up of 6.05 years. MASLD was not associated with an increased incidence of HCC in patients with CHB (HR: 1.17; 95 % CI: 0.77-1.79; p = 0.466). The cumulative incidence of HCC increased with the number of fulfilled cardiometabolic criteria (0-2 criteria vs. ≥ 3 criteria) (HR: 3.93; 95 % CI: 1.89-8.19; p < 0.001).Age (HR: 1.03, 95 % CI 1.01-1.06, p = 0.010), male sex (HR: 3.17; 95 % CI 1.34-7.53, p = 0.009), diabetes (HR: 2.81; 95 % CI 1.54-5.12, p < 0.001), and cirrhosis (HR:3.03; 95 % CI 1.57-5.5.86, p < 0.001) were independently associated with HCC development.

Conclusions

It was not MASLD, but rather the presence of multiple cardiometabolic risk factors in patients with CHB that was associated with the risk of HCC in those receiving antiviral treatment. Furthermore, older age, male sex, diabetes, and cirrhosis aggravated the risk of HCC in patients with CHB.

Characterizing Unique Clinical and Virological Profiles in Concurrent Chronic Hepatitis B and Metabolic Dysfunction-Associated Liver Disease: Insights from a Population-Based Cohort Study

Background: The concurrent presence of chronic hepatitis B virus (CHB) infection and metabolic dysfunction-associated steatotic liver disease (MASLD) presents a unique clinical scenario with implications that are not yet fully understood. This study aims to characterize the distinct clinical and virological features of CHB in the context of MASLD and evaluate its impact on disease progression and outcomes. Methods: Utilizing a comprehensive health maintenance organization database, this study included 1186 patients with CHB from 2000-2020. Patients were categorized into two groups: CHB-MASLD (n = 188) and CHB alone (n = 998). CHB diagnosis was confirmed by serological markers, while MASLD was diagnosed based on imaging and cardiometabolic risk factors. Comparative analysis and multiple regression models were applied to assess variables related to viral parameters and clinical outcomes. Results: The CHB-MASLD group was older (mean age of 45.2 vs. 39.1, p < 0.001) with higher rates of obesity (46.8% vs. 23.8%, p < 0.001), diabetes (36.2% vs. 17.3%, p < 0.001), and dyslipidemia. Distinct viral profiles included higher HBeAg negativity (96.2%), a higher rate of HBeAg-negative infection (70.4% vs. 63.8%; p < 0.001), and increased HBeAg seroconversion under treatment. Cirrhosis was more prevalent in the CHB-MASLD group (9.6% vs. 4.4%, p = 0.007), while HCC rates were comparable. Multivariate analysis identified age, male gender, chronic active hepatitis, and diabetes as predictors of cirrhosis. Conclusions: CHB-MASLD patients were distinguished by a higher prevalence of metabolic features, along with a distinct viral profile marked by increased chronic HBeAg infection, higher rates of HBeAg seroconversion, and a potential association with worse disease outcomes.

Effect of metabolic dysfunction‑associated fatty liver disease on the risk of hepatocellular carcinoma in patients with chronic hepatitis B: A systematic review and meta‑analysis

Hepatocellular carcinoma (HCC) remains an important complication in patients with chronic hepatitis B (CHB). An association between the presence of metabolic dysfunction-associated fatty liver disease (MAFLD) and an increased HCC risk in patients with CHB may exist; however, the exact nature of this possible association remains unclear. The present study conducted a comprehensive meta-analysis by pooling data from 18 studies encompassing 23,927 participants. The odds ratios (ORs) were calculated using a random-effects inverse-variance model, and heterogeneity was assessed using Cochran's Q test and the I² statistic. In addition, subgroup analyses were performed on the basis of geographical region, study design and follow-up length. Publication bias and meta-regression were also assessed. The overall pooled OR for the association between MAFLD and HCC risk in patients with CHB was 1.053 (95% CI, 0.704-1.576), which suggested a lack of association. Heterogeneity was observed across studies. Subgroup analyses demonstrated a potentially protective effect for MAFLD on the risk of HCC in patients in Asian countries (OR, 0.783; 95% CI, 0.568-1.080) and the opposite effect in other regions (OR, 4.380; 95% CI, 2.440-7.864). Analysis of the prospective cohort studies suggested a significant protective effect for MAFLD (OR, 0.479; 95% CI, 0.365-0.629), while analysis of retrospective cohorts did not. The publication bias assessment was inconclusive and the meta-regression failed to identify heterogeneity sources. The association between MAFLD and HCC risk in patients with CHB appeared to be multifactorial and may vary on the basis of geographical region and study design. While the exact mechanisms remain elusive, the potential protective effect demonstrated in certain subgroups warrants further investigation.

Effect of fatty liver and fibrosis on hepatocellular carcinoma development in patients with chronic hepatitis B who received nucleic acid analog therapy

The number of patients with fatty liver has been increasing worldwide; however, the significance of fatty liver in patients with chronic hepatitis B who are receiving nucleic acid analog (NA) therapy remains unclear. Thus, we aimed to determine whether fatty liver affects the development of hepatocellular carcinoma (HCC) in patients receiving NA therapy. This study included 445 patients who received NA therapy, and the development of HCC was investigated. The primary outcome was the association between fatty liver and HCC development. During a mean follow-up period of 7.4 years, 46 patients (10.3%) developed HCC. No significant difference in the cumulative incidence of HCC was observed between patients with fatty liver and those without (p = 0.17). Multivariable analysis for age, gender, platelet count, alanine aminotransferase level at 1 year following NA therapy, and fatty liver revealed that the presence of fatty liver was not a significant factor for HCC development (hazard ratio [HR]: 0.96, 95% confidence interval [CI]: 0.5-1.9). In another multivariable analysis for advanced fibrosis, gender, and fatty liver, advanced fibrosis was found to be a significant factor for HCC development (HR: 9.50, 95% CI: 5.1-18) but not fatty liver (HR: 0.90, 95% CI: 0.5-1.7). In conclusion, in patients with chronic hepatitis B who received NA therapy, advanced fibrosis was found to be an important risk factor for HCC development but not fatty liver, suggesting the importance of providing treatment before the progression of liver fibrosis regardless of the presence of fatty liver.

Hepatitis B virus infection combined with nonalcoholic fatty liver disease: Interaction and prognosis

Hepatitis B virus (HBV) infection is still one kind of the infectious diseases that seriously threaten human health. Nonalcoholic fatty liver disease (NAFLD) has become the most common chronic liver disease worldwide. HBV infection complicated with NAFLD is increasingly common. This review mainly describes the interaction between HBV infection and NAFLD, the interaction between steatosis and antiviral drugs, and the prognosis of HBV infection complicated with NAFLD. Most studies suggest that HBV infection may reduce the incidence of NAFLD. NAFLD can promote the spontaneous clearance of hepatitis B surface antigen (HBsAg), but whether it affects antiviral efficacy has been reported inconsistently. HBV infection combined with NAFLD can promote the progression of liver fibrosis, especially in patients with severe steatosis. The outcome of HBV infection combined with NAFLD predisposing to the progression of HCC remains controversial.

Steatosis, HBV-related HCC, cirrhosis, and HBsAg seroclearance: A systematic review and meta-analysis

BACKGROUND AND AIMS

NAFLD and chronic hepatitis B (CHB) infection are common etiologies of HCC. The impact of hepatic steatosis on HCC in CHB, as well as its relationship with the development of cirrhosis, fibrosis, and HBsAg seroclearance, remains controversial.

APPROACH AND RESULTS

Data from observational studies were collected through PubMed, EMBASE, and the Cochrane Library from inception to February 1, 2022. Outcomes of interest included the association of hepatic steatosis with HCC, cirrhosis, advanced fibrosis, and HBsAg seroclearance, expressed in terms of pooled ORs. Additional subgroup and sensitivity analyses were performed to validate the robustness of findings. A total of 34 studies with 68,268 patients with CHB were included. Hepatic steatosis was associated with higher odds of HCC (OR, 1.59; 95% CI, 1.12-2.26; I²  = 72.5%), with the association remaining consistent in Asia (OR, 1.56; 95% CI, 1.08-2.25), studies with a median follow-up duration of ≥5 years (OR, 2.82; 95% CI, 1.57-5.08), exclusion of alcohol use (OR, 1.71; 95% CI, 1.01-2.91), and biopsy-proven steatosis (OR, 2.86; 95% CI, 1.61-5.06), although no significant association was noted among nucleos(t)ide analogue-treated patients (OR, 1.05; 95% CI, 0.62-1.77). Steatosis was associated with the development of cirrhosis (OR, 1.52; 95% CI, 1.07-2.16; I²  = 0%) and HBsAg seroclearance (OR, 2.22; 95% CI, 1.58-3.10; I²  = 49.0%).

CONCLUSIONS

Hepatic steatosis was associated with an increased risk of HCC and cirrhosis among patients with CHB but with a higher chance of achieving a functional cure, highlighting the importance of identifying concomitant steatosis in CHB.

Clinical impact and mechanisms of hepatitis B virus infection concurrent with non-alcoholic fatty liver disease

ABSTRACT

Chronic hepatitis B (CHB) virus infection is an important threat to global health despite the administration of vaccines and the use of antiviral treatments. In recent years, as the prevalence of obesity and metabolic syndrome has increased, non-alcoholic fatty liver disease (NAFLD) in patients with CHB has become more common. Both diseases can lead to liver fibrosis and even hepatocellular carcinoma, but the risk of dual etiology, outcome, and CHB combined with NAFLD is not fully elucidated. In this review, we assess the overlapping prevalence of NAFLD and CHB, summarize recent studies of clinical and basic research related to potential interactions, and evaluate the progressive changes of treatments for CHB patients with NAFLD. This review increases the understanding of the relationship and mechanisms of interaction between steatosis and hepatitis B virus infection, and it provides new strategies for the future clinical management and treatment of CHB combined with NAFLD.
