まとめ
アザチオプリン (AZA) は,全身性白血球症 (SLE) の患者で重度の骨髄抑制と脱毛を引き起こす可能性があります. AZA治療中の副作用の迅速な認識と管理は極めて重要です.
科学分野:
- リウマトロジ
- 免疫学
- 皮膚科
背景:
- システム性赤血球性狼 (SLE) は複雑な自己免疫疾患で,様々な症状が表れます.
- アザチオプリン (AZA) は,軽度から中等度のSLEに対する一般的な免疫抑制剤です.
- 重度の脱毛は,AZA治療の珍しい,しかし可能な副作用です.
研究 の 目的:
- システム性白血病 (SLE) の患者でアザチオプリン (AZA) と関連した重度の白血病および脱毛の症例を報告する.
- SLEの管理におけるAZAによる悪影響の認識の重要性を強調する.
主な方法:
- ミコフェノラートモフェチルとヒドロキシクロロキンを服用していた45歳の女性患者はAZAに切り替えられました.
- 患者さんはAZAを投与開始後,重度の白血病と脱毛症を発症しました.
- AZA誘発の骨髄抑制と脱毛症の診断は,血液学の診察によって行われた.
主要な成果:
- 治療開始から6週間後,重度の白血病と有意な脱毛が発生した.
- AZAは中止され,患者は再びミコフェノラートモフェチルに切り替えられました.
- 白血球の数は数週間で正常に戻ったが,髪の再生には約3ヶ月かかりました.
結論:
- 骨髄抑制と白血病は,SLE患者におけるAZAの重要な副作用である.
- 重度の脱毛もAZA毒性の表れである可能性があります.
- 早期診断と介入は,SLEにおけるAZA関連合併症の管理に不可欠です.

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Drugs for Treatment of Ulcerative Colitis in IBD
236
Ulcerative colitis is a chronic inflammatory condition primarily affecting the colon and rectum. The primary drugs used in the treatment of ulcerative colitis are aminosalicylates. They exhibit anti-inflammatory and immunosuppressive properties. They modulate inflammatory mediators and inhibit the activity of nuclear factor κB (NF-κB). Aminosalicylates also reduce inflammation by inhibiting prostaglandin and leukotriene production and decreasing neutrophil chemotaxis and superoxide...

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
267
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...

Immunodeficiency 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.

Autoimmune Disorders

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.

Skin Cancer
4.5K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
