Insights

Global elimination of chronic hepatitis B (CHB) is achievable with new antiviral therapies and biomarkers. Novel treatments targeting the virus or host aim to improve outcomes and potentially achieve a functional cure for CHB.

Area of Science:

  • Hepatology
  • Virology
  • Immunology

Background:

  • Chronic hepatitis B (CHB) infection presents significant global health challenges, contributing to morbidity and mortality.
  • Understanding CHB pathophysiology and clinical outcomes is crucial for developing effective elimination strategies.
  • Novel therapeutic targets are actively being investigated to improve treatment prospects for CHB.

Purpose of the Study:

  • To review the cascade of cure for CHB, considering viral genome and protein persistence.
  • To discuss novel antiviral agents in clinical development targeting the virus or host.
  • To explore the potential of new biomarkers, such as serum hepatitis B core-related antigen and HBV RNA, in predicting outcomes and monitoring treatment response.

Main Methods:

  • Literature review of recent advances in CHB pathophysiology and treatment.
  • Analysis of novel antiviral agents in various stages of clinical development.
  • Evaluation of emerging biomarkers for predicting clinical outcomes and treatment efficacy.

Main Results:

  • Several novel antiviral agents targeting the virus or host are in clinical development.
  • Serum hepatitis B core-related antigen and HBV RNA show promise as predictive markers for hepatocellular carcinoma and virological relapse.
  • These novel markers may also serve to monitor treatment response in clinical trials.

Conclusions:

  • Global elimination of CHB faces challenges including low awareness and limited access to care.
  • Strategies like birth dose vaccination, antiviral therapy, and complication screening can reduce CHB burden.
  • Expanded treatment options and the pursuit of early functional cure are realistic goals for the next decade.

Anticholinesterase Agents: Poisoning and Treatment01:26

Anticholinesterase Agents: Poisoning and Treatment

Anticholinesterases, also known as cholinesterase inhibitors, work by blocking the breakdown of acetylcholine, leading to its accumulation in the synaptic cleft. This accumulation indirectly enhances both muscarinic and nicotinic actions. These agents are classified as reversible or irreversible based on their mechanism of action.     
Irreversible agents form a strong bond with the cholinesterase enzyme, making it inactive. The breakdown of the phosphorylated enzyme is...

Psychosis: Goals of Pharmacotherapy

Antipsychotic drugs are a crucial treatment method for acute and chronic psychoses, bipolar illness, and behavioral disorders. The selection of these drugs depends on several factors, including the state of the disease, clinical judgment, possible drug interactions, and the patient's sensitivity to adverse effects. In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation.

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents

Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF

Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...

Effect of Hepatic Disease on Pharmacokinetics: Dose Adjustments Due to Hepatic Impairment

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...

Hepatic Portal System01:21

Hepatic Portal System

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...
