Insights

This review examines the immune system's overreaction in severe COVID-19 (coronavirus disease 2019). It explores how this hyperinflammation contributes to severe illness and discusses therapies targeting the immune response.

Area of Science:

  • Immunology
  • Virology
  • Infectious Diseases

Background:

  • The global spread of SARS-CoV-2 (the virus causing COVID-19) necessitates urgent therapeutic interventions.
  • Evidence suggests that severe COVID-19 outcomes are linked to a dysregulated host immune response, characterized by hyperinflammation and cytokine release.
  • Understanding this immune dysregulation is crucial for developing effective treatments.

Purpose of the Study:

  • To elucidate the mechanisms underlying immune dysregulation in SARS-CoV-2 infection.
  • To review current research on immunomodulatory therapies for COVID-19.
  • To identify therapeutic strategies targeting the excessive host immune response.

Main Methods:

  • Literature review of immunological responses to SARS-CoV-2.
  • Analysis of studies investigating immunomodulatory agents.
  • Synthesis of current evidence on cytokine storm and immune dysregulation in COVID-19.

Main Results:

  • SARS-CoV-2 infection can trigger a detrimental hyperinflammatory immune response.
  • Cytokine release syndrome plays a significant role in COVID-19 pathogenesis and severity.
  • Various immunomodulatory therapies are under investigation to mitigate this excessive immune response.

Conclusions:

  • Immune dysregulation and hyperinflammation are key drivers of severe COVID-19 morbidity and mortality.
  • Targeting the host immune response offers a promising therapeutic avenue for COVID-19 treatment.
  • Further research into immunomodulatory therapies is essential for managing the COVID-19 pandemic.

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...

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.

Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids

Glucocorticoids, a class of anti-inflammatory drugs, are pivotal in treating moderate to severe Crohn's disease by inducing remission. They exhibit their anti-inflammatory action by inhibiting the production of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1, and chemokines like IL-8. In addition, they reduce the expression of inflammatory cell adhesion molecules and inhibit gene transcription of nitric oxide synthase, phospholipase A2, cyclooxygenase-2...

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs

Asthma is a chronic respiratory condition for which new therapeutic avenues, including anti-inflammatory drugs like mast cell stabilizers and anti-IgE treatments, continue to be developed.
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
