概括

牛皮和代谢综合征有共同的肠道微生物组联系. 这项研究发现了特定的微生物和生物标志物变化,如Akkermansia,为代谢综合征患者的牛皮提供了新的诊断和治疗策略.

科学领域:

微生物学
免疫学
代谢疾病

背景情况:

牛皮 (PsO) 和代谢综合征 (MetS) 经常同时发生,但潜在的机制尚不清楚.
肠道微生物群对免疫和代谢平衡至关重要,但其在pso与mets中的具体作用尚未完全理解.
鉴定生物标志物对于了解pso患者的病理生理学至关重要.

研究的目的:

研究患有PsO和MetS (PM) 与仅患有MetS (M) 患者之间的肠道微生物组成和功能差异.
识别潜在的微生物生物标志物,用于诊断和预测MTS患者的PsO.
阐明肠道微生物群在代谢障碍和牛皮之间的相互作用中的作用.

主要方法:

在29名PM患者和29名M患者的临床参数,肠道微生物多样性和社区组成的比较分析.
基因组分析以确定不同组之间的MetaCyc和KEGG途径.
对已识别的微生物生物标志物的诊断和预测性能进行评估.

主要成果:

在PM和M组之间观察到微生物多样性和组成的显著差异.
微粒组的微生物差异与高密度脂蛋白 (HDL) 负相关,与血清尿酸 (SUA) 呈正相关,而M组的趋势则相反.
在PM中,像糖素生物合成和L-氨酸降解这样的关键途径是显著的,而在M中,黄和胡卜素生物合成是丰富的.包括Akkermansia在内的8种生物标志物显示出强大的诊断预测能力.

结论:

在代谢综合征患者的牛皮病理生理学中,肠道微生物失调起着重要作用.
特定的微生物特征和生物标志物,如Akkermansia,可以帮助诊断和预测MetS中的PsO.
这些发现为预防,诊断和治疗Pso提供了新的见解和潜在策略.

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...

Irritable Bowel Syndrome I: Introduction

375

Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:
Altered...

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

419

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...

Bacterial Flora of the Large Intestine

642

The gut microbiome is formed by a vast and diverse community of bacteria that colonizes our large intestine. These bacteria start residing in the gut from birth and continue diversifying throughout life, influenced by factors such as diet, lifestyle, and stress. The gut bacterial community also includes bacteria from food and those that enter the colon through the anus.
The normal gut flora of the colon plays a critical role in generating essential vitamins such as vitamins K, B5, and B7.

Anatomy of the Intestines

73.9K

Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...
