まとめ
腸内障害はクローン病 (CD) と関連しているが,その役割は不明である. 糞便微生物移植 (FMT) はCDの可能性を示していますが,その有効性を確認するにはさらなる研究が必要です.
科学分野:
- 胃腸内科
- 微生物学
- 免疫学
背景:
- クローン病 (Crohn's disease) は慢性的な胃腸炎症疾患である.
- 腸内細菌の不均衡である腸内細菌の不均衡は,CD患者で一貫して観察されています.
- CDの病原性 (原因または結果) に関するディズバイオシスの正確な役割は不明である.
研究 の 目的:
- クローン病における腸内微生物の役割について
- CDに対するプロバイオティクスの治療的可能性と糞便微生物群移植 (FMT) を評価する.
- 現在の研究成果,限界,将来の方向性を強調する.
主な方法:
- ランダム化試験,メタ解析,臨床観察を含む主要な研究の分析.
- 腸の機能不全,プロバイオティクス,FMTの関係に注目してください.
- サンプルサイズ,対照群,フォローアップ期間などの研究制限の評価
主要な成果:
- ディスバイオシスはCDの一貫した特徴ですが,その原因は確立されていません.
- プロバイオティクス,プレバイオティクス,シンバイオティクスは,CDの寛解に有効性を示していません.
- 糞便微生物移植 (FMT) は,CDに対する効果が一貫せず,無害であるように見えます.
結論:
- 腸内不活性症はおそらくCDの病原化に寄与するが,その因果的な役割についてはさらなる調査が必要である.
- 現在の証拠は,CD寛解を誘発または維持するための信頼できる治療法としてFMTをサポートしていません.
- 大規模で標準化されたランダム化制御試験は,CDの管理におけるFMTの治療的役割を明確にするために不可欠です.

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...

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF
230
Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

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...

Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids
201
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...

Inflammatory Bowel Disease V: Surgical Management
206
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.
Here are some common surgical interventions for IBD:

Inflammatory Bowel Disease IV: Pharmacological Management
185
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.
