Summary
Immune checkpoint inhibitors can cause hypophysitis, a serious condition affecting the pituitary gland. Early detection and management are crucial for cancer patients to prevent life-threatening adrenal crises.
Area of Science:
- Oncology
- Immunology
- Endocrinology
Background:
- Immune checkpoint inhibitors (ICIs) are novel cancer therapies.
- ICIs can induce immune-related adverse events (irAEs), including autoimmune endocrinopathies.
- Hypophysitis is a significant irAE, potentially leading to adrenal crisis.
Purpose of the Study:
- To review the pathogenesis, risk factors, diagnosis, and management of ICI-related hypophysitis.
- To differentiate between anti-CTLA-4 and anti-PD-1/anti-PD-L1 antibody-induced hypophysitis.
- To propose strategies for early detection and optimal hormone replacement therapy.
Main Methods:
- Literature review summarizing current knowledge on ICI-related hypophysitis.
- Analysis of clinical characteristics, diagnostic criteria, and treatment approaches.
- Discussion of specific ICI agents and their associated hypophysitis profiles.
Main Results:
- ICI-related hypophysitis presents with diverse clinical manifestations and requires prompt diagnosis.
- Anti-CTLA-4 and anti-PD-1/anti-PD-L1 antibodies have distinct associations with hypophysitis.
- Hormone replacement therapy is a cornerstone of management.
Conclusions:
- Early identification and management of ICI-related hypophysitis are vital for patient outcomes.
- Targeted monitoring strategies can improve early detection in at-risk populations.
- Further research into pituitary autoimmunity pathophysiology is warranted.

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.

01:25Immunodeficiency Diseases
1.2K
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.

282
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...
