Insights

Novel cancer, autoimmune, and neurological therapies can weaken the immune system, increasing risks of opportunistic infections like viral, fungal, and reactivation of tuberculosis or hepatitis B.

Area of Science:

  • Immunology
  • Oncology
  • Neurology
  • Rheumatology

Background:

  • Novel therapeutic agents have advanced oncologic, rheumatologic, and neurologic disorder treatments.
  • These advanced therapies modulate immune function, leading to specific infectious complications.

Purpose of the Study:

  • To summarize the impact of novel therapeutic agents on the pathogenesis and spectrum of associated infections.
  • To highlight the infectious risks associated with immunomodulatory treatments.

Main Methods:

  • Literature review and synthesis of clinical data.
  • Analysis of infectious complications linked to specific novel agents.

Main Results:

  • Purine analogues and alemtuzumab are associated with opportunistic viral/fungal infections.
  • Bortezomib increases herpes zoster incidence; rituximab may cause hepatitis B reactivation.
  • Monoclonal antibodies and tumor necrosis factor-α inhibitors are linked to progressive multifocal leukoencephalopathy, tuberculosis reactivation, and fungal infections.

Conclusions:

  • Understanding the immune-modulating effects of novel therapies is crucial for managing infectious risks.
  • Proactive monitoring and management are essential to mitigate infections in patients receiving these advanced treatments.

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.

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists01:28

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists

Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy.  SP binds and activates...

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...

Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Immunodeficiency Diseases01:25

Immunodeficiency Diseases

Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents01:29

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...
