Durability of hepatitis b surface antigen seroclearance studied in real-world data from electronic health records

Durability of hepatitis b surface antigen seroclearance studied in real-world data from electronic health records
2023-09-19
(Press-News.org) In a study published in the journal Genes & Diseases, researchers from The Second Affiliated Hospital of Chongqing Medical University analyzed data from an extensive dataset comprising over 70,000 HBsAg-positive individuals at The Second Affiliated Hospital of Chongqing Medical University. They compared two groups: those achieving HBsAg seroclearance through NAs monotherapy (168 patients) and those through IFN monotherapy (30 patients). NAs monotherapy patients were older, with a higher proportion achieving HBsAg seroclearance during treatment (48.8% vs. 30.0%). They also had a more favorable immune response, with a higher percentage developing concomitant anti-HBs. The NAs-monotherapy group had more individuals with normal ALT levels (78.6% vs. 40.0%). The time to achieve HBsAg seroclearance and therapy duration were similar between the groups, but NAs monotherapy showed a trend towards longer times. During follow-up, patients on NAs monotherapy had a significantly lower rate of HBsAg seroreversion compared to IFN monotherapy patients (4.9% vs. 33.3%). The one-year and three-year probabilities of confirmed HBsAg seroclearance were significantly higher with NAs therapy (one-year: 0.960 vs. 0.691; three-year: 0.931 vs. 0.641), indicating a more sustained functional cure. NAs monotherapy was independently associated with a lower risk of HBsAg seroreversion. Most patients experienced HBsAg seroreversion within the first year after seroclearance. IFN monotherapy patients with positive anti-HBs had a higher probability of confirmed HBsAg seroclearance during follow-up, while this difference was not seen in NAs monotherapy patients. This study provides valuable insights into the durability of HBsAg seroclearance induced by NAs or IFN monotherapy, with NAs monotherapy showing better outcomes and lower risk of recurrence. Age and ALT levels were also identified as factors associated with HBsAg seroreversion. Understanding these findings can guide clinicians in making informed treatment decisions for patients with chronic Hepatitis B, ensuring better clinical outcomes.

The researchers anticipate that these findings will contribute to the development of more effective and personalized therapeutic strategies for CHB patients in the future. The study highlights the importance of continued research in this area and the potential for leveraging electronic health record data to gain deeper insights into disease management and treatment outcomes.

Tiny sea creatures reveal the ancient origins of neurons

Tiny sea creatures reveal the ancient origins of neurons
2023-09-19
A study in the journal Cell sheds new light on the evolution of neurons, focusing on the placozoans, a millimetre-sized marine animal. Researchers at the Centre for Genomic Regulation in Barcelona find evidence that specialized secretory cells found in these unique and ancient creatures may have given rise to neurons in more complex animals.  Placozoans are tiny animals, around the size of a large grain of sand, which graze on algae and microbes living on the surface of rocks and other substrates found in shallow, warm seas. The blob-like and pancake-shaped creatures are so simple that they live without any body parts or organs. These animals, thought to have ...

Argyle study reveals crucial third clue to finding new diamond deposits

2023-09-19
Curtin University researchers studying diamond-rich rocks from Western Australia’s Argyle volcano have identified the missing third key ingredient needed to bring valuable pink diamonds to the Earth’s surface where they can be mined, which could greatly help in the global hunt for new deposits. While it is known that for diamonds to form there needs to be carbon deep in the Earth, and for these diamonds to turn pink they must be subjected to forces from colliding tectonic plates, the new study has found the third ingredient needed for the presence of pink diamonds at surface ...

Poor oral health could lessen survival from head and neck cancer

Poor oral health could lessen survival from head and neck cancer
2023-09-19
An international study has revealed strong associations between oral health and survival among people diagnosed with head and neck cancer. Specifically, better oral health, as evidenced by the number of natural teeth and dental visits prior to the time of diagnosis, was associated with increased survival. Importantly, those who had more frequent dental visits were more likely to have their cancer diagnosed at an earlier, and less deadly, stage of the disease than those who had few or no dental visits. The study, by researchers at UNC Lineberger ...

Premenstrual disorders, timing of menopause, and severity of vasomotor symptoms

2023-09-19
About The Study: In this study of 3,635 female participants in the U.S., premenstrual disorders (PMDs) were associated with increased risks of early menopause and moderate or severe vasomotor symptoms (VMS). PMDs may be indicative of underlying physiology linked to early menopause and VMS, suggesting a phenotype observable during the reproductive years that may allow clinicians to target women at risk of earlier menopause and subsequent health risks later in the life course. Authors: Yihui Yang, M.P.H., and Donghao Lu, M.D., Ph.D., of the Karolinska Institutet in Stockholm, Sweden are the corresponding authors. To ...

Study finds two antibiotics for children with sinusitis equally effective, but one had fewer side effects

2023-09-19
Brigham researchers found that patients prescribed amoxicillin-clavulanate had higher rates of gastrointestinal symptoms and yeast infections than those prescribed amoxicillin Acute sinusitis is one of the most common causes for children to be put on antibiotic medications, with patients in the United States filing nearly 5 million antibiotic prescriptions every year to treat the condition. The drugs amoxicillin and amoxicillin-clavulanate make up most of those prescriptions, but there is a lack of consensus on which should be first-line ...

Women given new insight into blood clot risk

2023-09-19
New research from Queen Mary University of London, published in iScience, shows an increased risk of blood clots in women who have any combination of a particular gene mutation, oestrogen use, or common medical conditions – specifically: obesity, high blood pressure, high cholesterol, and kidney disease. Women with the Factor V Leiden (FVL) gene mutation who had been prescribed oestrogen had more than double the risk of blood clotting compared to women who did not have this mutation. And almost 20% of the women who carry FVL, ...
