INTRODUCTION
Sorafenib was historically the standard of care for advanced hepatocellular carcinoma (aHCC) until it was superseded by the combination of atezolizumab and bevacizumab. Thereafter, several novel first-line combination therapies have demonstrated favorable outcomes. The efficacies of these treatments in relation to current and previous standards of care are unknown, necessitating an overarching evaluation.
METHODS
A systematic literature search was conducted on PubMed, EMBASE, Scopus, and the Cochrane Controlled Register of Trials for phase III randomized controlled trials investigating first-line systemic therapies for aHCC. Kaplan-Meier curves for overall survival (OS) and progression-free survival (PFS) were graphically reconstructed to retrieve individual patient-level data. Derived hazard ratios (HRs) for each study were pooled in a random-effects network meta-analysis (NMA). NMAs were also conducted using study-level HRs for various subgroups, according to viral etiology, Barcelona Clinic Liver Cancer (BCLC) staging, alpha-fetoprotein (AFP) levels, macrovascular invasion, and extrahepatic spread. Treatment strategies were ranked using scores.
RESULTS
Among 4,321 articles identified, 12 trials and 9,589 patients were included for analysis. Only two therapies showed OS benefit over sorafenib: combined anti-programmed-death and anti-VEGF pathway inhibitor monoclonal antibodies (Anti-PD-(L)1/VEGF Ab), including atezolizumab-bevacizumab and sintilimab-bevacizumab biosimilar (HR = 0.63, 95% CI = 0.53-0.76) and tremelimumab-durvalumab (HR = 0.78, 95% CI = 0.66-0.92). Anti-PD-(L)1/VEGF Ab showed OS benefit over all other therapies except tremelimumab-durvalumab. Low heterogeneity ( = 0%) and inconsistency (Cochran's = 0.52, = 0.773) was observed. scores for OS ranked Anti-PD-(L)1/VEGF Ab as the best treatment in all subgroups, except hepatitis B where atezolizumab-cabozantinib ranked highest for both OS and PFS, as well as nonviral HCC and AFP ≥400 μg/L where tremelimumab-durvalumab ranked highest for OS.
CONCLUSION
This NMA supports Anti-PD-(L)1/VEGF Ab as the first-line therapy for aHCC and demonstrates a comparable benefit for tremelimumab-durvalumab which also extends to certain subgroups. Results of the subgroup analysis may guide treatment according to baseline characteristics, while pending further studies.

Meta-Analysis
BACKGROUND
Hepatitis delta virus (HDV) coinfects with hepatitis B virus (HBV) causing the most severe form of viral hepatitis. However, its exact global disease burden remains largely obscure. We aim to establish the global epidemiology, infection mode-stratified disease progression, and clinical outcome of HDV infection.
METHODS
We conducted a meta-analysis with a random-effects model and performed data synthesis.
RESULTS
The pooled prevalence of HDV is 0.80% (95% confidence interval [CI], 0.63-1.00) among the general population and 13.02% (95% CI, 11.96-14.11) among HBV carriers, corresponding to 48-60 million infections globally. Among HBV patients with fulminant hepatitis, cirrhosis, or hepatocellular carcinoma, HDV prevalence is 26.75% (95% CI, 19.84-34.29), 25.77% (95% CI, 20.62-31.27), and 19.80% (95% CI, 10.97-30.45), respectively. The odds ratio (OR) of HDV infection among HBV patients with chronic liver disease compared with asymptomatic controls is 4.55 (95% CI, 3.65-5.67). Hepatitis delta virus-coinfected patients are more likely to develop cirrhosis than HBV-monoinfected patients with OR of 3.84 (95% CI, 1.79-8.24). Overall, HDV infection progresses to cirrhosis within 5 years and to hepatocellular carcinoma within 10 years, on average.
CONCLUSIONS
Findings suggest that HDV poses a heavy global burden with rapid progression to severe liver diseases, urging effective strategies for screening, prevention, and treatment.

Meta-Analysis Review
BACKGROUND
Lack of accurate and timely diagnosis of hepatitis poses obstacles to effective treatment, disease progression prevention, complication reduction, and life-saving interventions of patients. Utilizing machine learning can greatly enhance the achievement of timely and precise disease diagnosis. Therefore, we carried out this systematic review and meta-analysis to explore the performance of machine learning algorithms in predicting viral hepatitis.
METHODS
Using an extensive literature search in PubMed, Scopus, and Web of Science databases until June 15, 2023, English publications on hepatitis prediction using machine learning algorithms were included. Two authors independently extracted pertinent information from the selected studies. The PRISMA 2020 checklist was followed for study selection and result reporting. The risk of bias was checked using the International Journal of Medical Informatics (IJMEDI) checklist. Data were analyzed using the 'metandi' command in Stata 17.
RESULTS
Twenty-one original studies were included, covering 82 algorithms. Sixteen studies utilized five algorithms to predict hepatitis B. Ten studies used five algorithms for hepatitis C prediction. For hepatitis B prediction, the SVM algorithms demonstrated the highest sensitivity (90.0%; 95% confidence interval (CI): 77.0%-96.0%), specificity (94%; 95% CI: 90.0%-97.0%), and a diagnostic odds ratio (DOR) of 145 (95% CI: 37.0-559.0). In the case of hepatitis C, the KNN algorithms exhibited the highest sensitivity (80%; 95% CI:30.0%-97.0%), specificity (95%; 95% CI: 58.0%-99.0%), and DOR (72; 95% CI: 3.0-1644.0) for prediction.
CONCLUSION
SVM and KNN demonstrated superior performance in predicting hepatitis. The proper algorithm along with clinical practice could improve hepatitis prediction and management.

Meta-Analysis Review
BACKGROUND
Acute hepatitis B infection is associated with severe liver disease and chronic sequelae in some cases. The purpose of this review was to determine the efficacy of nucleoside analogues (NA) (lamivudine versus entecavir) compared to placebo or no intervention for treating acute primary HBV infection.
METHODS
A meta-analysis for drug intervention was performed, following a fixed-effect model. Randomized controlled trials (RCTs) and quasi-randomized studies that evaluated the outcomes of NA in acute hepatitis B infection were included. The following outcomes were considered: virological cure (PCR negative), elimination of acute infection (seroconversion of HBsAg), mortality, and serious adverse events.
RESULTS
Five trials with 627 adult participants with severe acute hepatitis B defined by biochemical and serologic parameters were included. Virological cure did not favor any intervention: OR 0.96, 95% CI 0.54 to 1.7 ( = 0.90), I2 = 58%. Seroconversion of HBsAg to negative favored placebo/standard-of-care compared to lamivudine: OR 0.54, 95% CI 0.33 to 0.9 ( = 0.02), I2 = 31%. The only trial that compared entecavir and lamivudine favored entecavir over lamivudine (OR: 3.64, 95% CI 1.31-10.13; 90 participants). Adverse events were mild.
CONCLUSION
There is insufficient evidence that NA obtain superior efficacy compared with placebo/standard-of-care in patients with acute viral hepatitis, based on low quality evidence.

Review
BACKGROUND
We conducted a systematic review in order to summarize the available data on pancreatitis associated with viral hepatitis.
METHODS
A comprehensive literature search of Medline, Scopus and ISI Web of Science databases was conducted and papers eligible for the inclusion identified.
RESULTS
In total, 46 studies reporting data on 73 patients were included in the analysis. Most of the cases were diagnosed in Asia (57.53%), followed by North America (23.29%), and Europe (13.70%). Most of the patients were affected by hepatitis A virus (HAV) (42.47%), followed by hepatitis E virus (HEV) (28.77%), hepatitis B virus (HBV) (8.22%), and hepatitis C virus (HCV) (1.37%), while 17.81% at the time of diagnosis were classified as affected by "hepatitis virus". Pancreatitis was severe in 32.88% of cases. The respiratory system was affected in 2.74% of patients, 6.85% experienced renal failure, while 5.48% experienced a multiorgan dysfunction syndrome (MODS). Four patients (5.48%) needed pancreatic surgery. Despite the treatment, 21.92% of patients died. We identified fulminant hepatitis ( < 0.0001), MODS ( < 0.0001) and severe pancreatitis ( < 0.0001) to be significantly more present in patients who died in comparison to cured ones.
CONCLUSION
Increased awareness of pancreatic involvement in viral hepatitis is needed because it can have a substantial impact on therapeutic approaches and outcomes.

Meta-Analysis Review
BACKGROUND AND AIM
We aim to assess the association between maternal hepatitis C virus (HCV) viral load and human immunodeficiency virus (HIV) coinfection and the risk for mother-to-child transmission (MTCT) among pregnant women infected with HCV.
METHODS
A literature search of the Medline, Embase, Central, Science Citation Index Expanded (SCIE), Conference Proceedings Citation Index-Science (CPCIS), Scopus, Literature Latino-Americana e do Caribe em Ciências da Saúde (LILACS), and WHO Global Index Medicus databases, from inception to June 21, 2022, was performed. Studies that reported the incidence HCV-MTCT were included. Pooled effect estimates were calculated using the random-effects model, and Holm-Bonferroni correction was performed for multiple pooled associations.
RESULTS
The present meta-analysis included 26 studies involving 4934 newborns with maternal HCV infection. Pregnant women with HCV viremia exhibited increased risk for MTCT (odds ratio [OR] 8.25 [95% confidence interval (CI) 4.65-14.63]) compared with those negative for HCV-RNA. Multiple subgroup analysis revealed that the HCV viremia/HIV-positive group demonstrated the highest risk for HCV MTCT, followed by the HCV viremia mono-infected group, while HCV-RNA-negative women demonstrated the lowest risk for HCV MTCT. Among females with HCV viremia, elevated risk for MTCT was found among subjects with a viral load ≥ 6 log copies/mL compared with those with viral load < 6 log copies/mL (OR 4.58 [95% CI: 2.52-8.34]).
CONCLUSION
The incidence of HCV MTCT was increased among pregnant women with detectable HCV viremia and was even higher in those with a viral load ≥ 6 log copies/mL. HIV coinfection further increased the risk for HCV MTCT.

Review
AIM
The purpose of the current study is to analyze the potential association between viral hepatitis and the severity of COVID-19.
BACKGROUND
Coronavirus disease 2019 (COVID-19) is a worldwide concern that has created major issues with many aspects. It is important to identify the risk factors for severe outcomes of this disease. To date, no association between viral hepatitis and severe COVID-19 has not been established.
METHODS
Through November 5, 2020, the databases of PubMed, Google Scholar, and medRxiv were systematically searched using specific keywords related to the focus of the study. All articles published on COVID-19 and viral hepatitis were retrieved. The Mantel-Haenszel formula with random-effects models was used to obtain the risk ratio (RR) along with its 95% confidence intervals (CIs) for dichotomous variables. The two-tailed -value was set with a value ≤0.05 considered statistically significant. Restricted-maximum likelihood meta-regression was done for several variables, such as age, gender, hypertension, diabetes, and other liver disease.
RESULTS
Analysis results included a total of 16 studies with a total of 14,682 patients. Meta-analysis showed that viral hepatitis increases the risk of developing severe COVID-19 (RR 1.68 (95% CI 1.26 - 2.22), = 0.0003, = 21%, random-effect modeling). According to the meta-regression analysis, the association between viral hepatitis and severe COVID-19 was not influenced by age ( = 0.067), diabetes ( = 0.057), or other liver disease ( = 0.646).
CONCLUSION
An increase of severe COVID-19 risk is associated with viral hepatitis. To reduce the risk of COVID-19, patients with viral hepatitis should be monitored carefully.

BACKGROUND
Whether viral hepatitis increases the risk of cholangiocarcinoma (CCA) has been controversial. The reasons for the differences between previous research results may be related to the differences in sample size, region, living environment and course of disease. A meta-analysis is needed to clarify the correlation between them and select the key population for early screening of CCA. Meta-analysis was used to explore the relationship between viral hepatitis and the risk of CCA, so as to provide evidence for the prevention and treatment of CCA.
METHODS
We systematically searched EmBase, SinoMed, PubMed, Web of Science China National Knowledge Infrastructure, and Wanfang databases. The quality of the included literature was evaluated using the Newcastle Ottawa Scale. Before merging the effect quantities, the data was first subjected to heterogeneity testing. Heterogeneity testing was evaluated using I (the proportion of heterogeneity variation to overall variation). Subgroup analysis was used to identify sources of heterogeneity in this study. The effect odds ratio (OR) of various studies was extracted or calculated for consolidation. Beta's rank correlation, Egger's Law of Return and funnel plot were used to test publication bias. Conduct subgroup analysis based on the regions included in the literature.
RESULTS
A total of 2,113 articles were retrieved, and a total of 38 articles were included in the meta-analysis. There are 29 case-control studies and 9 Cohort study, including 333,836 cases and 4,042,509 controls. The combined risk estimate of all studies showed a statistically significant increased risk of CCA, extrahepatitis and intrahepatitis incidence with hepatitis B virus (HBV) infection (OR =1.75, OR =1.49, and OR =2.46, respectively). The combined risk estimate of all studies showed a statistically significant increased risk of CCA, extrahepatitis and intrahepatitis incidence with hepatitis C virus (HCV) infection (OR =1.45, OR =2.00, and OR =2.81, respectively). The research points of HCV and CCA were asymmetric, indicating that there may be publication bias in the study of HCV and CCA.
CONCLUSIONS
HBV and HCV infection could increase the risk of CCA. Therefore, in clinical practice, attention should be paid to CCA screening and early prevention of HBV and HCV infected patients.

BACKGROUND
The liver has a critical role in the metabolism of glucose and lipids. Chronic hepatitis B virus (HBV) or hepatitis C virus (HCV) infection leads to a spectrum of liver disease including chronic hepatitis, cirrhosis and hepatocellular carcinoma. Metabolic syndrome (MetS) has a rising incidence owing to an epidemic of type 2 diabetes mellitus (T2DM) and obesity. Non-alcoholic fatty liver disease is a liver manifestation of MetS and has become the most common cause of chronic liver disease worldwide.
AIM
To summarise the interplay among hepatitis viruses, MetS and its components.
METHODS
We searched the literature about HBV, HCV infection, MetS, fatty liver and its components from PubMed.
RESULTS
With respect to the viral replication cycle, lipids are important mediators between viral entry and hepatocyte in HCV infection, but not in HBV infection. Thus, HCV infection is inversely associated with hyperlipidaemia and lipid rebound occurs following sustained viral response induced by interferon-based therapy or direct antiviral agents. In addition, HCV infection is positively associated with insulin resistance, hepatic steatosis, MetS and the risk of T2DM and atherosclerosis. In contrast, HBV infection may protect infected subjects from the development of MetS and hepatic steatosis. Accumulating evidence suggests that HBV infection is inversely associated with lipid metabolism, and exhibits no conclusive association with insulin resistance or the risk of T2DM and arteriosclerosis.
CONCLUSIONS
In patients with viral hepatitis and concurrent metabolic diseases, a multidisciplinary approach should be given rather than simply antiviral treatment.

BACKGROUND
Nowadays, Viral Hepatitis can be comparable to the big three communicable diseases: tuberculosis, HIV/AIDS, and malarial infections. The main purpose of this study was to summarize the prevalence of viral Hepatitis in India from peer-reviewed articles published from February 2000 to February 2021.
MATERIALS AND METHODS
We conducted a systematic search on Science Direct, Scopus, Medline, PubMed, Web of Science, Google Scholar, and other open access journals. We evaluated all relevant papers that looked into the prevalence of viral Hepatitis systematically. Finally, 28 studies on viral Hepatitis published from February 2000 to February 2021 have been selected. These studies have been conducted across the northern, southern, central, eastern, and western regions of India.
RESULTS
Twenty-eight full-text publications were obtained and evaluated consisting of 45,608 research participants. Hepatitis A was found to range from 2.1% to 52.5%. Hepatitis B was found in a wide range of individuals, ranging from 0.87% to 21.4% of the population. Hepatitis C was found to range from 0.57% to 53.7%. The majority of the children were affected by hepatitis A, and 47.4% of third-trimester pregnant mothers were affected by hepatitis E. Diabetes, hospital admission, history of jaundice, history of surgeries, and heterosexual contact were the leading modes of acquiring HBV and HCV infections. As a result of its great magnitude, this disease poses a severe threat to the national healthcare system.
CONCLUSION
Effective public health measures are urgently needed to minimize the burden of viral Hepatitis and eliminate the disease.
