Abstract

fetched live from OpenAlex

Abstract Co‐existing chronic hepatitis B virus (CHB) infection and metabolic dysfunction associated steatotic liver disease (MASLD) can exert complex effects on hepatic metabolism, requiring mechanistic study. CHB participants were assessed for MASLD and the impact of hepatic steatosis/metabolic syndrome (MetS) on novel viral and immunological markers. In this prospective, cohort study, untreated CHB subjects were assessed for liver disease by non‐invasive tests (i.e. FibroScan, controlled attenuation parameter, CAP). Subjects were tested for cytokines and IFN‐γ ELISPOT assay to HBV Surface (S) and Core (C) proteins. Standard HBV serological, exploratory biomarkers and deep sequencing of HBV S and C genes were performed. In 53 subjects (median age 45 years [SD = 10.6], 35% F, 56% Asian, 20% Black, 3% White), 94% (50) HBeAg negative, 63% genotype B/C, mean HBV DNA 3.2 log 10 IU/mL (SD = 1.8), quantitative HBsAg 2.9 log 10 IU/mL (SD = 1.2) and HBV pgRNA 2.1 log 10 copies/mL (SD = 1.3). In enrolled subjects, the mean ALT was 41.9 U/L (SD = 24.0), FibroScan was 5.7 kPa (SD = 1.9) and CAP was 306.4 dB/m (SD = 49.0). The mean BMI was 28.2 kg/m 2 (SD = 4.2), 20% (11/53) had diabetes, 35% (19/53) dyslipidaemia and 24% (13/53) hypertension. Subjects with MetS and steatosis showed lower HBV markers ( p < .01), higher HBV S diversity ( p = .02) and greater frequency of HBV variants associated with host‐anti‐viral immune escape. Pro‐inflammatory cytokine levels and HBV‐specific cellular responses were higher in participants with hepatic steatosis. In CHB, MASLD/hepatic steatosis was associated with HBV variants and systemic immune responses potentially impacting liver disease progression despite low‐level viraemia.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
