Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists01:27

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

753
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: Cannabinoids01:21

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids

872
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,...

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

3.8K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

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

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

701
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...

COPD: Management Using Bronchodilators and Corticosteroids

1000
Chronic obstructive pulmonary isease (COPD) involves a group of progressive lung disorders characterized by persistent airflow limitation and chronic respiratory symptoms. Asthma-COPD Overlap Syndrome (ACOS), encompassing features of both asthma and Chronic obstructive pulmonary disease (COPD), is a group of progressive lung disorders that includes chronic bronchitis, emphysema, and refractory (non-reversible) asthma. ACOS leads to complex clinical presentations that combine the inflammatory...

Summary

Pulmonary consolidations are typically infections. However, this study highlights a rare case where chronic lymphocytic leukemia presented as lung consolidation and respiratory failure, responding to chemotherapy.

Area of Science:

  • Pulmonology
  • Oncology
  • Hematology

Background:

  • Pulmonary consolidations are commonly caused by infections.
  • Autoimmune and neoplastic processes can also cause pulmonary consolidations, though less frequently.
  • In patients with hematological malignancy, consolidations are often presumed to be infectious.

Purpose of the Study:

  • To describe a rare presentation of chronic lymphocytic leukemia (CLL).
  • To highlight pulmonary involvement in CLL as consolidations and respiratory failure.
  • To emphasize the importance of considering non-infective causes in immunosuppressed patients.

Main Methods:

  • Case report analysis.
  • Review of clinical presentation and treatment response.
  • Literature review on pulmonary manifestations of CLL.

Main Results:

  • The patient presented with pulmonary consolidations and type 1 respiratory failure.
  • The presentation mimicked an infectious process.
  • The condition responded favorably to systemic chemotherapy, indicating a neoplastic origin.

Conclusions:

  • Pulmonary involvement in chronic lymphocytic leukemia can manifest as consolidations and respiratory failure.
  • This presentation is rare and can be mistaken for infection.
  • Systemic chemotherapy may be an effective treatment for such cases.
