まとめ
便の腫瘍死滅因子α (TNFα) の測定は,炎症性腸疾患の活動をモニタリングするための簡単な方法を提供することができる. 活発なクローン病や潰瘍性大腸炎における濃度の上昇は,信頼できるバイオマーカーとしての可能性を示唆しています.
科学分野:
- 胃腸内科 胃腸内科
- 免疫学 免疫学とは

背景:
- 炎症性腸疾患 (IBD) の活動を評価することは困難です.
- 現在,IBD疾患の活動を測定する方法は複雑で時間がかかります.
- 腫瘍死滅因子α (TNFα) はIBDにおける重要な炎症媒介体である.
研究 の 目的:
- IBD疾患の活性に対する潜在的なバイオマーカーとして,便のTNFα濃度を評価する.
- 活発なIBD,不活性IBD,下痢,健康な対照群の子供における便のTNFαレベルを比較する.
主な方法:
- 便のサンプルは,IBDが活発な子供,IBDが不活発な子供,下痢の子供,そして健康な対照群から採取されました.
- 便のTNFα濃度は,特定の測定法を使用して測定されました.
- 統計分析により,異なるグループにおけるTNFαレベルを比較した.
主要な成果:
- 便のTNFα濃度は,クローン病 (中位994pg/g) と性大腸炎 (中位276-5982pg/g) が活発な子供において,対照群と比較して,著しく上昇した.
- 不活性IBDの患者では,便のTNFα濃度がコントロールレベルまで低下した.
- 正常な子供と下痢の子供には,小便のTNFα濃度の中央値が低い (それぞれ58 pg/gと45 pg/g).
結論:
- 便のTNFα濃度は,小児性炎症性腸疾患における疾患活動をモニタリングするための有望で単純なマーカーです.

01:17Gastritis-II: Pathophysiology
Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

01:28Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies
Peptic ulcer disease (PUD) presents with diverse symptoms depending on the location and severity of the ulcer. Clinical manifestations of peptic ulcer include dull pain and a burning sensation in the mid-epigastric region.
Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.

01:28Amebiasis
Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
01:26Gastritis II: Pathophysiology
The pathophysiology of gastritis begins with the colonization of the stomach lining by Helicobacter pylori (H. pylori). This bacterium spreads mainly via the oral-oral route through saliva or shared utensils, and can also be transmitted in overcrowded or unhygienic environments through contaminated water, despite its brief survival outside the body.ColonizationOnce ingested, H. pylori enters the stomach and begins colonization by navigating through the mucus layer lining the stomach wall. It...
01:20Inflammatory Bowel Disease II: Ulcerative Colitis
Ulcerative colitis is a chronic inflammatory disorder of the colon characterized by continuous mucosal inflammation that typically begins in the rectum and extends proximally in a uniform pattern. Its pathogenesis involves a complex interplay of genetic predisposition, immune dysregulation, and environmental influences. These factors converge to impair the colon’s epithelial defenses and promote an exaggerated inflammatory response against luminal contents.Breakdown of the Mucosal BarrierA...
01:25Inflammatory Bowel Disease III: Crohn's Disease
Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...
