Cytotoxic T Cells-mediated Immune Response01:27

Cytotoxic T Cells-mediated Immune Response

7.9K
Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...

Hypersensitivity Reactions: Cytolytic Reactions01:01

Hypersensitivity Reactions: Cytolytic Reactions

115
Type II hypersensitivity involves IgG and IgM antibodies targeting cell surface antigens, leading to cell destruction. This can occur through complement activation, antibody-dependent cell-mediated cytotoxicity (ADCC), or acting as opsonins for phagocytosis. When excessive, these reactions cause significant tissue damage.Drug-induced hemolytic anemia is a common example, where drugs like penicillin or cephalosporins bind to red blood cells, forming drug-protein complexes. These complexes...

Metastasis02:30

Metastasis

6.8K
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Cytomegalovirus Disease01:27

Cytomegalovirus Disease

7
Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...

Tumor Immunotherapy01:27

Tumor Immunotherapy

2.1K
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.

Area of Science:

  • Oncology
  • Clinical Pharmacy
  • Patient Safety

Background:

  • Extravasation of antitumoral compounds is a known risk during chemotherapy administration.
  • Effective management strategies are crucial to minimize patient morbidity and ensure treatment continuity.

Purpose of the Study:

  • To document the incidence and management of antitumoral compound extravasation over a 10-year period.
  • To evaluate the effectiveness of a standardized management approach.

Main Methods:

  • Retrospective analysis of 114 extravasation episodes from a medical day hospital unit.
  • Documentation of compound type, localization, symptoms, treatment, and outcomes.
  • Involvement of an interdisciplinary task force and adherence to dedicated guidelines.

Main Results:

  • Commonly associated symptoms included edema, erythema, and pain, particularly with anthracyclines, platinum compounds, and taxanes.
  • Monoclonal antibody extravasations (5 cases) occurred without sequelae.
  • Conservative management, supported by pharmacy and physiatric evaluation, was successful in all cases, with recovery within 48 hours post-antidote.
  • No surgical interventions were required.

Conclusions:

  • A standardized, interdisciplinary approach to antitumoral compound extravasation is effective.
  • This approach ensures satisfactory patient outcomes and can be recommended for broader clinical application.
