Insights

Tumor necrosis factor (TNF) inhibitors may offer a promising therapeutic strategy for Coronavirus disease 2019 (COVID-19). These agents could potentially reduce inflammation and prevent disease progression in infected patients.

Area of Science:

  • Immunology and Virology
  • Pharmacology and Therapeutics

Background:

  • Coronavirus disease 2019 (COVID-19) poses a global health challenge, with ongoing need for effective treatments beyond vaccines.
  • Elevated cytokine levels, particularly tumor necrosis factor (TNF), are implicated in severe COVID-19 pathogenesis and mortality.
  • Existing TNF blocker therapies for autoimmune diseases present a potential avenue for repurposing.

Purpose of the Study:

  • To examine the biological activities of TNF inhibitors relevant to COVID-19.
  • To review randomized controlled trials evaluating TNF inhibitors for COVID-19 treatment.

Main Methods:

  • Review of biological mechanisms of TNF inhibitors.
  • Analysis of existing clinical trial data on TNF inhibitors in COVID-19.

Main Results:

  • Early data suggest TNF inhibitors can reduce pro-inflammatory cytokines.
  • Further evaluation is needed to confirm efficacy in preventing COVID-19 progression.

Conclusions:

  • TNF inhibitors show potential as a therapeutic option for COVID-19.
  • Randomized controlled trials are crucial for assessing the benefit-risk profile of TNF inhibitors in COVID-19 patients.

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...

Tumor Immunotherapy01:27

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Inflammatory Bowel Disease IV: Pharmacological Management

Upon diagnosis, managing Inflammatory Bowel Disease (IBD) involves addressing several crucial aspects. The primary goals include resting the bowel, correcting malnutrition, and providing symptomatic relief. Resting the bowel may consist of medications to reduce inflammation and promote healing. Correcting malnutrition is essential, often requiring dietary adjustments and nutritional supplements. Symptomatic relief aims to ease pain, diarrhea, and other discomforts in IBD.

NF-κB-dependent Signaling Pathway

The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

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...
