まとめ
幹細胞移植後の急性移植対宿主疾患 (GVHD) の第三線治療は,糞便の微生物群移植 (FMT),メゼンキマストロマ細胞 (MSC) および体外光合成 (ECP) を含め,皮質耐性患者にとって有望である.
科学分野:
- 血液学
- 免疫学
- 移植医学
背景:
- 急性移植対宿主疾患 (GVHD) は,異種造血幹細胞移植 (HSCT) の後の主要な合併症であり,著しい罹病率と死亡率をもたらします.
- 全身用コルチコステロイドは,GVHDの確立された第一線治療法であり,ルクソリチニブは最近,コルチコ抵抗性の症例の第二線治療法として承認されました.
- 約40%の患者でルクソリチニブの有効性が限られているため,有効な第三線治療法の検討が必要である.
研究 の 目的:
- 急性GVHDのHSCT後の有望な第三線治療戦略を特定し評価する.
- 耐火性GVHDの管理における排泄微生物移植 (FMT),メゼンキマ・ストロマ細胞 (MSC),体外光合成 (ECP) の潜在的な役割について議論する.
- GVHD管理における予測マーカーとリスクに適応したアプローチの必要性を強調する.
主な方法:
- 急性GVHDの有望な第3線治療法について議論し,選択するためのワークショップが開催されました.
- GVHDのFMT,MSC注射,ECPに関する既存の文献と臨床データのレビュー
- パーソナライズされたGVHD治療のためのバイオマーカーを特定し,リスクスコアを開発することの重要性に関する議論
主要な成果:
- 糞便の微生物移植 (FMT),メゼンキマ・ストロマ細胞 (MSC) の注射,および体外フォトフェレス (ECP) は,皮質耐性急性GVHDの有望な第三線選択肢として特定されました.
- 治療の選択を導くために信頼できるバイオマーカーやスコアリングシステムを特定するために,激しい研究が進行中です.
- 栄養,感染症予防,組織再生などの サポートケアにおける進歩は極めて重要です.
結論:
- FMT,MSC,ECPは標準療法に耐性のある急性GVHDの患者にとって有効な第三線治療法です.
- 予測マーカーとリスクスコアの開発は 治療戦略の最適化と患者の成果の改善に不可欠です
- 急性GVHDの課題に取り組むには,新しい治療法とサポートケアを含む統合的管理アプローチが不可欠です.

Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids
200
Glucocorticoids, a class of anti-inflammatory drugs, are pivotal in treating moderate to severe Crohn's disease by inducing remission. They exhibit their anti-inflammatory action by inhibiting the production of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1, and chemokines like IL-8. In addition, they reduce the expression of inflammatory cell adhesion molecules and inhibit gene transcription of nitric oxide synthase, phospholipase A2, cyclooxygenase-2...

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.

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
264
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...
