Background And Aims: The liver cancer risk test (LCR1-LCR2) is a multianalyte blood test combining proteins involved in liver cell repair (apolipoprotein A1, haptoglobin), hepatocellular carcinoma (HCC) risk factors (gender, age, gamma glutamyl transpeptidase), a marker of fibrosis (alpha2-macroglobulin), and alpha-fetoprotein, a specific marker of HCC. The aim was to externally validate LCR1-LCR2 in hepatitis B.
Methods: Preincluded patients were from the Hepather cohort, a multicenter, multiethnic prospective study in 6071 patients. The coprimary study outcome was the negative predictive value of LCR1-LCR2 at 5 years for the occurrence of HCC and survival without HCC according to the predetermined LCR1-LCR2 cutoffs, adjusted for risk covariables and for chronic hepatitis B treatment and quantified using time-dependent Cox proportional hazards models. A post hoc analysis compared the number of patients needed to screen one cancer by LCR1-LCR2 and PAGE-B.
Results: A total of 3520 patients, 191 (5.4%) with cirrhosis, with at least 1 year of follow-up were included. A total of 76 HCCs occurred over a median (interquartile range) of 6.0 years (4.8-7.3) of follow-up. Among the 3367 patients with low-risk LCR1-LCR2, the 5-year negative predictive value was 99.3% (95% confidence interval = 99.0-99.6), with a significant Cox hazard ratio (6.4, 3.1-13.0; < .001) obtained after adjustment for exposure to antivirals, age, gender, geographical origin, HBe-Ag status, alcohol consumption, and type-2 diabetes. LCR1-LCR2 outperformed PAGE-B for number of patients needed to screen mean (95% CI), 8.5 (3.2-8.1) vs 26.3 (17.5-38.5; < .0001), respectively.
Conclusion: The performance of LCR1-LCR2 to identify patients with chronic hepatitis B at very low risk of HCC at 5 years was externally validated. ClinicalTrials.gov: NCT01953458.

Rationale: Mass vaccination, low cost of immunoglobulins, and new drugs led to the emergence of new, unusual patterns of hepatitis B serum markers. This study reported a rare case of hepatitis B with all 5 positive serum markers, including HBsAg, HBsAb, HBeAg, HBeAb, and HBcAb.
Patient Concerns: A 30-year-old female patient was admitted due to abnormal liver function.

Rationale: Current research on antiviral treatment in children is relatively limited, especially in children under 1 year old.
Patient Concerns: Liu XX, an 8-month-old infant (case number: 3001120473), presented to the hospital in August 2016 with a chief complaint of being "hepatitis B surface antigen positive for 8 months and experiencing abnormal liver function for 5 months."
Diagnoses: The patient was diagnosed as chronic hepatitis B cirrhosis (G3S3-4) with active compensatory phase.

Chronic hepatitis C virus (HCV) infection poses a major health risk worldwide, with patients susceptible to liver cirrhosis and hepatocellular carcinoma. This study focuses on the development of effective therapeutic strategies for HCV infection through the investigation of immunogenic properties of a DNA construct based on the NS3/4A gene of HCV genotype (g)3a. Gene expression of the mutagenized (mut) NS3/4A target genes was assessed through reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and Western blot analysis.

Hepatocellular carcinoma (HCC) is one of the most common forms of primary liver cancer worldwide. Herein, we present a review article that provides a broad overview of the current landscape of HCC, including the etiology, potential risk factors, and molecular pathways that can serve as potential therapeutic targets. The risk factors tend to vary depending on the geographic distribution; hepatitis B-induced cirrhosis and HCC occur more frequently in Asia and Sub-Saharan Africa, whereas metabolic disorders are the culprits in Western Europe and the Americas.

Background: Tissue damage by viral hepatitis is a major cause of morbidity and mortality worldwide. Oxidation reactions and reactive oxygen species (ROS) transform proteins and lipids in plasma low-density lipoproteins (LDL) into the abnormal oxidized LDL (ox-LDL). Hepatitis C virus (HCV) infection induces oxidative/nitrosative stress from multiple sources, including the inducible nitric oxide synthase (iNOS), the mitochondrial electron transport chain, hepatocyte NAD(P)H oxidases (NOX enzymes), and inflammation.
