まとめ
炎症性腸疾患の分布,慢性,活動 (IBD-DCA) のスコア付けシステムは,潰瘍性大腸炎 (UC) の生検に広く採用されています. ヒストロジカル・アクティビティは,内視的重症と相関しており,臨床試験の適用を助長しています.
科学分野:
- 胃腸内科
- ヒストパトロジー
- 臨床診断
背景:
- 潰瘍性大腸炎 (UC) の診断は複雑で,患者の生活の質に影響します.
- 標準化された報告はUCの一貫した診断と管理に不可欠です.
- 炎症性腸疾患の分布,慢性,活動 (IBD-DCA) のスコア付けシステムは,UCにおける標準化された大腸生検報告のために開発されました.
研究 の 目的:
- IBD-DCAスコアリングシステムの採用率を特定部門で評価する.
- IBD-DCAシステムからの組織学的発見とUC Endoscopic Index of Severity (UCEIS) を相関させる.
- IBD-DCAシステムの臨床実務と将来の研究における有用性を評価する.
主な方法:
- 炎症性腸疾患 (IBD) バイオプシーの449件を遡及的に検討し,291件でUCが確認された.
- IBD-DCAの報告形式の吸収率の分析
- IBD- DCAの間のケンドールのタウ相関分析は,116件のUCの組織学的活動とUCEISスコアを報告した.
主要な成果:
- IBD-DCA報告形式の採用はUCバイオプシーの95%を超えました.
- 組織学的な活動 (IBD- DCA) とUCEISのすべての成分 (τ > 0. 260, p < 0. 05) の間に中程度の正の相関が観察されました.
- IBD- DCAシステムを適用する際の変異は,直腸バイオプシーで確認され,組織学と内視鏡の間の不一致が確認されました.
結論:
- IBD- DCAシステムは高い吸収を示し,UCにおける内視的重症と中程度に相関しています.
- ヒストロ・エンドスコーピーの不一致は,サンプリングの違いやUCEISのパンコロニカルな性質から生じることがあります.
- この研究はIBD-DCAを臨床試験で再発の予測と治療指針として使用することを提唱しています.

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:

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...

Inflammatory Bowel Disease I: Ulcerative Colitis

Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
413
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...

Chronic Bowel Disorders: Introduction
540
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...
