Chemotherapy-Induced Nausea and Vomiting: Cannabinoids01:21

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids

712
Tetrahydrocannabinol (THC) is a phytocannabinoid that primarily interacts with the CB1 receptor, a type of G protein-coupled receptor (GPCR) predominantly in and around the chemoreceptor trigger zone (CTZ) and emetic center. THC also blocks the serotonin receptor activity in the dorsal vagal complex (DVC) by inhibiting serotonin release. THC exerts its anti-emetic effects through these interactions, which are beneficial for patients undergoing chemotherapy.
Two synthetic agonists of THC,...

Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...

Chemotherapy-Induced Nausea and Vomiting: Dopamine Receptor Antagonists01:29

Chemotherapy-Induced Nausea and Vomiting: Dopamine Receptor Antagonists

831
Dopamine receptor antagonists, also known as antipsychotic agents, are critical in managing chemotherapy-induced vomiting. These antiemetic agents block dopamine receptors in the chemoreceptor trigger zone (CTZ), inhibiting signal transmission to the vomiting center. Antipsychotic agents encompass phenothiazines (PTZ), butyrophenones, benzamides, and thienobenzodiazepines (Zyprexa), which are utilized for their antiemetic and sedative properties.
Phenothiazines, such as prochlorperazine...

Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists

618
5-HT3 receptor antagonists, such as dolasetron, granisetron (Kytril), ondansetron (Zofran), and palonosetron (Axoli), are crucial in managing chemotherapy-induced nausea and vomiting (CINV) and postoperative nausea. These drugs selectively block 5-HT3 receptors in the visceral vagal and spinal afferent nerves, chemoreceptor trigger zone, and the vomiting center. They have a rapid onset of action and can be given as a single dose before chemotherapy. Ondansetron and granisetron, in particular,...

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

605
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...

Summary
This summary is machine-generated.

Chemotherapy for prostate cancer with bone metastasis can cause chronic inflammation, increasing rheumatoid arthritis risk. Combining anti-inflammatory therapy with chemotherapy reduces this inflammation, potentially preventing joint injury in elderly patients.

Area of Science:

  • Oncology
  • Immunology
  • Rheumatology

Background:

  • Chronic inflammation is a key factor in rheumatoid arthritis (RA) development.
  • Prostate cancer with bone metastasis (PCa-BM) is common in the elderly, impacting prognosis.
  • Chemotherapy for PCa-BM can induce chronic inflammation, potentially increasing RA risk and complications.

Purpose of the Study:

  • To investigate the risk of chemotherapy-induced chronic inflammation on rheumatoid arthritis (RA) in prostate cancer with bone metastasis (PCa-BM) patients.
  • To evaluate the efficacy of anti-inflammatory interventions in mitigating these effects.

Main Methods:

  • Utilized in vitro and in vivo experiments to assess chemotherapy's inflammatory response in PCa-BM.
  • Introduced anti-inflammatory interventions to evaluate cytokine modulation.
  • Analyzed inflammatory and immunological changes within the PCa-BM tumor microenvironment.

Main Results:

  • Chemotherapy significantly activated inflammatory factors, including TNF-α, IL-6, IL-10, IL-17A, and p-STAT3, in the PCa-BM tumor microenvironment.
  • Anti-inflammatory intervention markedly reduced chemotherapy-induced chronic inflammatory cytokines linked to RA.
  • Observed elevated inflammatory biomarkers associated with RA development.

Conclusions:

  • Combined anti-inflammatory and chemotherapy effectively reduced tumor microenvironment inflammation, delaying tumor progression.
  • This combination therapy alleviated chronic inflammatory joint injury, suggesting a role in managing RA risk.
  • Recommended for elderly PCa-BM patients with musculoskeletal disorders to manage RA risk.
