概括
在血造干细胞移植 (HSCT) 患者中,富含乙氨基酸的食管炎是罕见的. 这项研究发现与条件损伤,移植对宿主病 (GVHD) 和移植过敏 (TAA) 有关.
科学领域:
- 胃肠病学
- 血液学
- 免疫学
背景情况:
- 富含乙氨基酸的食管炎,其特征是皮内乙氨基酸的增加,与包括乙氨基酸性食管炎 (EoE) 在内的各种疾病有关.
- 在受血造干细胞移植 (HSCT) 患者中,富含乙氨基酸的食道炎不常见,之前有一份报告将其与移植获得的过敏症 (TAA) 联系在一起.
研究的目的:
- 在HSCT患者中表现出富含乙氨基酸的食管活检的临床和病理特征.
主要方法:
- 一项多中心研究确定了10名HSCT患者患有丰富于乙氨基酸的食道炎.
- 分析了食道活检的临床数据和组织病理学发现.
- 检查的关键特征包括乙酸细胞计数,乙酸细胞脱粒,,亡体和皮细胞.
主要成果:
- 患者的中位数年龄为45岁,HSCT后的中位数为6个月.
- 病理发现包括乙酸性脱粒 (6例),乙酸性 (3例),质体 (5例) 和质细胞 (3例).
- 在HSCT后21天的患者中观察到移植对宿主疾病 (GVHD) 的特征,通常是胃肠外GVHD.
- 两名患者对药物产生TAA, 一名患者对输血产生过敏反应.
- 只有一个患者符合EoE的诊断标准.
结论:
- 在HSCT患者中,富含乙酸的食管炎与调节疗法诱导的损伤和GVHD有关.
- 移植过敏 (TAA) 也与这种人群中食性食道炎的发展有关.
- 由于研究的病例数量有限,需要进一步研究.

Gastritis-I: Introduction and Types
Gastritis, defined by the inflammation or irritation of the stomach lining or gastric mucosa, manifests in several distinct forms: acute, chronic, reactive, and a specific subtype known as autoimmune metaplastic atrophic gastritis.
Acute gastritis presents as a sudden inflammation triggered by various stressors to the stomach lining, such as exposure to corrosive agents, local irritants like aspirin and other NSAIDs, alcohol consumption, radiation therapy, physical trauma, severe burns, sepsis,...

Gastritis-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...

Peptic Ulcer Disease II: Pathophysiology
Peptic Ulcer Disease (PUD) is characterized by the development of ulcers in the stomach or duodenal mucosa. Its pathophysiology is complex, involving a balance between damaging and protective elements.
Damaging agents such as Helicobacter pylori, gastric acid, pepsin, and nonsteroidal anti-inflammatory drugs (NSAIDs) can weaken the mucosal defense, allowing hydrogen ions to infiltrate back and harm epithelial cells.

Gastritis 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...
Peptic Ulcer Disease I: Introduction
Peptic ulcer disease (PUD) involves breaks in the gastrointestinal tract's mucosal lining, primarily in the stomach and duodenum, with less frequent occurrences in the lower esophagus or near the pylorus.Ulcers can be acute or chronic. Acute ulcers are short-lived with minimal inflammation and heal quickly after the irritant is removed. Chronic ulcers persist, may recur, and often cause scarring due to ongoing tissue damage. Superficial erosions affect only the mucosal layer and are called...
Peptic Ulcer Disease II: Pathophysiology
Peptic ulcer disease develops when protective mechanisms of the gastrointestinal mucosa are overwhelmed by harmful factors, leading to localized erosions in the stomach or proximal duodenum. The main causes are Helicobacter pylori infection and chronic use of nonsteroidal anti-inflammatory drugs (NSAIDs).Helicobacter pylori–Induced InjuryBacterial Adaptation and Colonization:H. pylori is a spiral, Gram-negative bacterium adapted to the acidic stomach. and transmitted through oral-oral or...
