Cumulative hepatitis B surface antigen/hepatitis B virus DNA ratio in immune-tolerant hepatitis B patients
2025-08-21
(Press-News.org) Background and Aims
Patients with chronic hepatitis B virus (HBV) infection in the immune-tolerant phase may still experience hepatic inflammation and disease progression, and could benefit from early antiviral treatment. This study aimed to investigate changes in the cumulative hepatitis B surface antigen (HBsAg)/HBV DNA ratio in immune-tolerant patients during the transition to the immune-active phase, and to evaluate its potential in predicting the risk of disease progression.
Methods
This longitudinal study included 127 untreated immune-tolerant patients, who were followed for up to 10 years. An independent cohort of 109 subjects was retrospectively enrolled for external validation. The relationship between the cumulative HBsAg/HBV DNA ratio and the duration of immune tolerance or transition to the immune-active phase was examined. The predictive value of the ratio was assessed and validated.
Results
The relationship between the cumulative HBsAg/HBV DNA ratio and disease progression risk showed a non-linear pattern: below a ratio of 1.791, the risk of disease progression decreased rapidly as the ratio increased; above 1.791, the risk plateaued. The area under the curve for predicting disease progression was 0.67, 0.64, and 0.85 for cumulative HBsAg, HBV DNA, and the HBsAg/HBV DNA ratio, respectively. Multivariable Cox regression analysis revealed the cumulative HBsAg/HBV DNA ratio as an independent predictor of disease progression, with higher ratios associated with a lower risk. Prediction models incorporating this ratio were developed and externally validated, demonstrating strong performance and clinical utility.
Conclusions
This study identifies the cumulative HBsAg/HBV DNA ratio as an independent predictor of immune tolerance duration in patients with chronic HBV infection. A lower ratio correlates with an increased risk of transition from the immune-tolerant phase to the immune-active phase, particularly when it falls below 1.791, at which point the risk of disease progression increases sharply. Additionally, patients aged ≥30 years face a notably higher risk of disease progression, underscoring the need for vigilant monitoring in this population. These findings have important implications for the proactive management of immune-tolerant patients. Early detection of disease progression and timely antiviral treatment may ultimately improve clinical outcomes and societal benefits for individuals suffering from chronic HBV infection.

Biological systems have inspired the development of next-generation soft robotic systems with diverse motions and functions. Such versatility in soft robots—in terms of rapid and efficient crawling—can be achieved via asymmetric bending through bilayer-type actuators that combine responsive liquid crystal elastomers (LCEs) with flexible substrates. This, in turn, requires temperature-responsive LCEs with accurate temperature regulation via elaborate Joule heating configurations.
However, it is a complicated task owing to the difficulty in generating asymmetric motions using isotropic thermal distributions, necessitating simple temperature ...

A preclinical evaluation of a new ’dual-mode’ tracer agent shows promise in not only helping surgeons image and plan prostate cancer procedures, but also provide them with much more consistent and targeted guidance during surgery.
The agent uses a single tracer molecule labeled with Fluorine-18—a common isotope used in Positron Emission Tomography (PET) scans—for diagnostic imaging. It also provides a one-step, widely accessible solution that would enable combined fluorescence-guided and radio-guided surgery.
“Precision ...

Most of the drugs, plastics, and industrial materials widely used today are produced through chemical reactions. In general, most high-performance and sophisticated substances have complex structures, and their assembly involves multiple chemical reaction steps carried out one after another. This creates significant overhead, as each step requires specific conditions, reagents, and catalysts, as well as considerable energy and labor.
Tandem reactions offer a promising solution to this issue. The ...

PITTSBURGH, Aug. 21, 2025 – New research from the University of Pittsburgh School of Medicine and Cambridge University upends a long-standing belief about brain plasticity.
A study published today in Nature Neuroscience shows that the brain’s built-in “body map” remains stable even when the body undergoes drastic changes, such as the loss of a limb.
The findings have implications for the treatment of “phantom limb” pain and suggest that achieving reliable restoration of sensation and controlling robotic replacement limbs via brain-computer interfaces may be more viable in the long term than previously thought.
