Summary
Hepatitis B surface antigen (HBsAg) seroclearance durability was studied in over 300 patients. Higher hepatitis B virus (HBV) surface antibody levels may reduce relapse risk after treatment.
Area of Science:
- Hepatology
- Virology
- Immunology
Background:
- Hepatitis B surface antigen (HBsAg) seroclearance is an optimal treatment endpoint for chronic hepatitis B.
- Limited data exist on the durability of response and relapse rates post-HBsAg seroclearance.
- Interferon (IFN)-based therapy is used for chronic hepatitis B, with over 300 patients achieving HBsAg seroclearance at our center.
Purpose of the Study:
- To investigate the durability of response after HBsAg seroclearance in chronic hepatitis B patients.
- To determine the impact of hepatitis B virus (HBV) surface antibody (Anti-HBs) levels on relapse rates.
- To analyze long-term outcomes following IFN-based antiviral treatment.
Main Methods:
- Retrospective analysis of over 300 patients with chronic hepatitis B who achieved HBsAg seroclearance.
- Monitoring of HBsAg seroclearance durability and relapse rates.
- Assessment of Anti-HBs antibody levels and their correlation with relapse.
Main Results:
- Durability of HBsAg seroclearance was evaluated in a large cohort.
- The relationship between Anti-HBs levels and the risk of relapse was analyzed.
- Findings provide insights into long-term outcomes after antiviral therapy.
Conclusions:
- Sustained HBsAg seroclearance is achievable with IFN-based therapy.
- Anti-HBs antibody levels may play a crucial role in preventing relapse after HBsAg seroclearance.
- Further research is needed to optimize treatment strategies for chronic hepatitis B.

01:15Brick Durability, Strength, and Appearance
649
Brick durability, strength, and appearance are crucial factors in construction, influencing the choice of bricks for specific applications. The process of freeze-thaw, for instance, significantly affects brick durability. This phenomenon occurs when water absorbed by a brick expands as it freezes, potentially causing damage when it melts and refreezes. Bricks are graded for durability: SW-grade bricks are the most durable, offering high strength and low water absorption, followed by MW-grade...

01:08Effect of Hepatic Disease on Pharmacokinetics: Dose Adjustments Due to Hepatic Impairment
267
Hepatic impairment, characterized by decreased liver function, does not uniformly mandate adjustments in drug dosage. Whether dosage modifications are necessary depends on various factors related to the drug's metabolism and elimination pathways. If a drug is primarily excreted via the kidneys and bypasses significant hepatic processing, if it undergoes minimal metabolic transformation in the liver, or if it is volatile and primarily expelled through the lungs, dose adjustments may not be...

01:21Hepatic Portal System
5.7K
The hepatic portal system, a critical part of our circulatory framework, transports nutrient-laden, deoxygenated blood from the gastrointestinal tract and spleen to the liver. This ingenious system plays an indispensable role in maintaining our body's metabolic equilibrium.
At its core, the hepatic portal vein is the result of a confluence of the superior and inferior mesenteric veins along with the splenic vein. Each of these veins has a unique role. The superior mesenteric vein is...

01:26Effect of Hepatic Disease on Pharmacokinetics: Drug Dosing and Hepatic Blood Flow
222
Chronic liver disease significantly impacts drug metabolism due to alterations in hepatic blood flow and enzyme accessibility. This disruption affects the body's pharmacokinetics—the movement and processing of drugs within the system. Key enzymes crucial for metabolizing medications become less accessible, changing how drugs are processed and utilized. Furthermore, liver disease influences the synthesis of plasma proteins, such as albumin and globulins, which play critical roles in drug...

01:21Cell-surface Signaling
54.0K
Hormones—or any molecule that binds to a receptor, known as a ligand—that are lipid-insoluble (water-soluble) are not able to diffuse across the cell membrane. In order to be able to affect a cell without entering it, these hormones bind to receptors on the cell membrane. When a first messenger, a hormone, binds to a receptor, a signal cascade is set off, causing second messengers, proteins inside the cell, to become activated, resulting in downstream effects.

3.1K
The immune system is a complex network of cells and molecules that protects the body from foreign invaders. T cells, a type of white blood cell, play a crucial role in this process. They recognize and attack foreign substances, such as pathogens, that enter the body.
T cells require the help of antigen-presenting cells (APCs), which process foreign antigens into smaller fragments that can be recognized by T cells. These APCs are highly specialized cells that efficiently internalize antigens...
