概括
小肠细菌过度生长 (SIBO) 在患有代谢功能障碍相关的脂肪性肝病 (MASLD) 的肥胖患者中更为常见,特别是患有肝纤维化的患者. 这表明SIBO可能会推动MASLD的进展.
科学领域:
- 肝病学 肝病学是一种肝病学.
- 胃肠病学 胃肠病学
- 代谢疾病 代谢疾病
背景情况:
- 与代谢功能障碍相关的脂肪性肝病 (MASLD) 和肥胖是全球普遍存在的健康问题.
- 肠道失生症是导致MASLD病变的一个因素.
- 小肠细菌过度生长 (SIBO) 在肥胖个体中MASLD进展中的特定作用尚不清楚.
研究的目的:
- 在肥胖患者中调查SIBO和MASLD严重程度之间的关联.
- 为了确定SIBO是否在患有MASLD的肥胖患者中比对照患者更为普遍.
- 在MASLD中探索SIBO和肝纤维化之间的关系.
主要方法:
- 一项观察性,横截面研究,涉及患有或没有MASLD的肥胖患者,通过肝活检诊断.
- MASLD谱系包括代谢功能障碍相关的脂肪性肝脏 (MASL),没有纤维化的MASH (MASH-NF) 和带有纤维化的MASH (MASH-F).
- 使用标准化乳糖呼吸测试来诊断SIBO.
主要成果:
- 在44.2%的MASLD患者中检测到SIBO,而对照组中则为14.2% (p=0.0363).
- 与非纤维性MASLD (33.3%;p=0.0165) 相比,有纤维化MASH (MASH-F) 的SIBO患病率较高 (65.2%).
- SIBO的存在与肝硬化症的程度没有相关性.
结论:
- 在肥胖患者中,MASLD和SIBO之间存在显著的关联,主要是由于存在肝纤维化.
- 这些发现表明,肠道失生症,特别是SIBO在MASLD的进展中具有潜在的致病作用.
- 需要进一步的研究来阐明将SIBO和MASLD进展联系在一起的机制.

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...

Chronic Bowel Disorders: Introduction
440
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...

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...
