まとめ
炎症性腸疾患 (IBD) に対するチオプリン療法では,軽度の感染症,特にウイルス感染症のリスクが増加しました. しかし,患者の中等から重度の感染症の発生率を有意に上昇させることはありませんでした.
科学分野:
- 胃腸内科 胃腸内科
- 免疫学 免疫学とは
- 薬理学 薬理学とは
背景:
- チオプーリンは,炎症性腸疾患 (IBD) の治療法として確立されています.
- IBD患者のチオプリン使用に関連する感染リスクに関する実際のデータは限られています.
- 感染パターンの理解は,IBD管理の最適化に不可欠です.
研究 の 目的:
- チオプリン治療を開始する前と後のIBD患者における感染の発生率,タイプ,および重症度を決定する.
- 臨床環境におけるチオプリンの感染リスクに対する実際の影響を評価する.
- IBDにおけるチオプーリンの使用に関する情報に基づいた臨床意思決定のためのデータを提供する.
主な方法:
- スウェーデンのスカネ大学病院でチオプリン未使用のIBD患者 (2015年−2022年) のレトロスペクティブコホート研究.
- チオプリン投与開始前と後の2年間,電子医療記録から収集された感染データ.
- 分析には,発生率,発生率比率 (IRR) および信頼区間 (CI) が含まれていました.
主要な成果:
- 感染症の発生率は,チオプリン投与開始後の100人年当たり22.4から31.8に増加した.
- チオプーリンの使用は,軽度の感染症 (IRR=1.8) とウイルス感染症 (IRR=2.3) のリスクの増加と相関していました.
- 中度から重度の感染症の有意な増加は認められなかった (IRR=1.2).
結論:
- チオプーリンは,IBD患者における軽度の感染症,特にウイルス型感染症の発生率が高いことと関連しています.
- ティオプリンを使用すると,中等から重度の感染症のリスクは有意に増加しませんでした.
- 重度の感染症に関しては一般的に安全ですが,軽度の感染症の負担は,患者の遵守と生活の質のための臨床的注意を正当化します.

Factors Affecting the Risk of Infection
13.9K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
563
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...

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
936
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Inflammatory Bowel Disease IV: Pharmacological Management
817
Upon diagnosis, managing Inflammatory Bowel Disease (IBD) involves addressing several crucial aspects. The primary goals include resting the bowel, correcting malnutrition, and providing symptomatic relief. Resting the bowel may consist of medications to reduce inflammation and promote healing. Correcting malnutrition is essential, often requiring dietary adjustments and nutritional supplements. Symptomatic relief aims to ease pain, diarrhea, and other discomforts in IBD.

Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
