概括
长期使用氨酸可以导致氨酸胆血管病,一种模仿原发性硬化性胆道炎 (PSC) 的肝脏疾病. 这种情况不如PSC炎症,可能与胺诱导的囊炎有关.
科学领域:

- 毒理学 毒理学 毒理学
- 病理学 病理学 病理学
背景情况:
- 胺,一种分离性麻醉剂,越来越多地用于疼痛管理和娱乐.
- 长期的胺滥用与各种器官毒性有关,包括尿路损伤.
- 胆管疾病 - - 胆管疾病 - - 曾经与慢性胺使用有关.
研究的目的:
- 描述基胺诱导胆血管病变的临床,成像和病理特征.
- 要区分胺胆血管病与其他胆道疾病,特别是原发性硬化胆道炎 (PSC).
主要方法:
- 八名患者的回顾性审查,他们有胺使用史和胆血管病变的证据.
- 分析临床数据,肝功能测试,成像 (胆血管学) 和肝活检发现.
- 比较特征与已知特征的原发性硬化性胆管炎.
主要成果:
- 确定了8名患者 (6名男性,2名女性;中位数年龄36岁) 长期使用胺素 (中位数12年) 和胆血管病变.
- 常见的发现包括异常的肝检测,扩散的肝内胆道狭窄和轻微的肝外胆道扩张.
- 肝脏活检显示慢性胆血管病变与轻度炎症和纤维化;四个病例患有围导纤维化或通道消灭.
- 六例中存在胺诱导的囊炎;炎症性肠病和自身抗体在很大程度上缺席.
结论:
- 胺胆血管病与PSC具有生物化学,放射学和组织学相似之处,但似乎不那么炎症和渐进.
- 诊断线索包括与胺诱导囊炎的关联,没有炎症性肠病,以及轻微的肝外导管扩张.

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...

274
In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess...

30
Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...

32
Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...
