AI Article Synopsis

  • Aprepitant (Emend) is a new antiemetic drug that specifically targets NK(1) receptors associated with substance P.
  • Blocking these NK(1) receptors in the brain's vomiting center helps reduce nausea and vomiting caused by chemotherapy.
  • There's potential for NK(1) receptor blockade in other parts of the central nervous system to treat conditions like depression and stress-related disorders.

Article Abstract

Novel antiemetic agents such as the newly approved aprepitant (Emend) target receptors for substance P, known as neurokinin-1 (NK(1)) receptors. When NK(1) receptors are blocked in the vomiting center of the brainstem, chemotherapy-induced emesis is reduced. It is possible that blocking NK(1) receptors elsewhere in the CNS will lead to therapeutic actions in depression and other stress-related disorders.

Introduction: Data on the optimal management of patients with hematologic malignancies and chemotherapy-induced nausea and vomiting (CINV) are lacking, particularly for multiday chemotherapy regimens. We report our institutional experience in patients with B-cell lymphoma receiving multiday dose-adjusted R-EPOCH chemotherapy utilizing two CINV prophylaxis strategies.

Methods: We performed a retrospective, single-center, cohort study evaluating hospitalized patients with aggressive non-Hodgkin B-cell lymphoma receiving DA-R-EPOCH (April 2016 to October 2022).

Background: The tachykinin substance P (SP) facilitates learning and memory processes after its central administration. Activation of its different receptive sites, neurokinin-1 receptors (NK1Rs), as well as NK2Rs and NK3Rs, was shown to influence learning and memory. The basal ganglia have been confirmed to play an important role in the control of memory processes and spatial learning mechanisms, and as part of the basal ganglia, the globus pallidus (GP) may also be involved in this regulation.

Background/aim: Vascular pain associated with NK1 receptor antagonists, particularly fosaprepitant, remains a significant challenge in cancer chemotherapy. The present study investigated the incidence of vascular pain with the administration of fosaprepitant and fosnetupitant and assessed the psychological burden on nurses performing venipuncture.

Patients And Methods: We conducted a prospective observational study involving 115 cancer patients receiving NK1 receptor antagonists via peripheral venous catheters.

Background: NK-1 receptor antagonists (NK-1RAs) are proven to be successful in preventing chemotherapy-induced nausea and vomiting (CINV). The safety profile of NK-1RAs has not been systematically analyzed in the real world. This pharmacovigilance study investigated the differences in adverse events (AEs) between NK-1RAs.

More than the sparse infiltration in glioblastoma, cytotoxic T lymphocytes (CTLs) also function inefficiently and overexpress the inhibitory markers, especially the identified NK cell receptor (NK1.1). However, most studies solely focus on how to augment tumor-infiltrating CTLs and overlook their killing maintenance.
