まとめ
免疫チェックポイント阻害剤 (ICI) は,自己免疫血液溶解性貧血 (AIHA) を引き起こす可能性があります. このケースはAIHAが解決した後に 別のICIで再挑戦が成功し 癌患者に希望を与えています
科学分野:
- 腫瘍学
- 免疫学
- 血液学
背景:
- 免疫チェックポイント阻害剤 (ICI) はがん治療に変化をもたらしたが,重度の免疫関連の有害事象 (irAEs) を引き起こしている.
- 薬剤誘発性自己免疫性血液溶解性貧血 (AIHA) は,ICIの中止を必要とするかもしれない深刻なIRAEです.
- 重度の血液学的IRAE後のICI患者の再挑戦の安全性は十分に理解されていません.
研究 の 目的:
- ペンブロリズマブ誘発のAIHAの後,代替ICIで再挑戦を成功させたケースを提示する.
- 重度のIREを患った患者に免疫療法の継続の可能性を調査する.
主な方法:
- 66歳の女性で 子宮内膜がんが再発しました
- ペンブロリズマブによる治療は暖かいAIHAの発生につながった.
- ステロイド治療によるAIHA解消後にデトロリマブによる再挑戦が成功しました.
主要な成果:
- ペムブロリズマブ誘発の暖かいAIHAは,コルチコステロイド療法によって解消された.
- デトラリマブによるリチャレンジは実行可能であり,有望な結果を示した.
- 患者はAIHAの再発なしに代替ICIを許容しました.
結論:
- 選択された患者には,以前から重度の発作があった場合,代替ICIによるリチャレンジが有効な選択肢である可能性があります.
- リチャレンジの決定には,IRAEのタイプ,重症度,および臨床状況の慎重な検討が不可欠です.
- このケースは,IREsにもかかわらず,がん治療の有効性を維持するための潜在的な戦略を強調しています.

Treatment Resistant Cancers
2.6K
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...

Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.

Immunodeficiency Diseases
3.7K
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.

Autoimmune Disorders
2.4K
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Tumor Immunotherapy
2.5K
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.

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
755
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...
