概括

这项研究发现,Fusobacterium varium可能会使慢性乙型肝炎 (CHB) 恶化,而Veillonella parvula可能会对其进行保护. 在肠道微生物群代谢物和CHB进展之间没有发现因果关系.

科学领域:

微生物学微生物学
肝病学肝病学是一种肝病学.
遗传学是一个遗传学.

背景情况:

慢性乙型肝炎 (CHB) 是一个重要的全球健康问题.
肠道微生物群在CHB病原发生中的作用仍然不完全理解.
研究肠道细菌和CHB之间的潜在因果关系对于开发新型治疗策略至关重要.

研究的目的:

探索肠道微生物群和/或其代谢物与慢性乙型肝炎 (CHB) 的进展之间的潜在因果关系.
为了确定可能影响CHB发育或进展的特定肠道细菌或代谢物.

主要方法:

采用双样本的孟德尔随机化 (MR) 方法.
利用来自亚洲和欧洲队列的全基因组关联研究 (GWAS) 数据.
逆方差加权 (IVW) 方法是主要的分析策略,并补充了敏感性分析以评估稳定性.

主要成果:

*Fusobacterium varium*在训练组中显示出与CHB进展 (OR=1.122,p=0.022) 的正相关性.
*Veillonella parvula*在训练组中与CHB进展 (OR=0.917,p=0.021) 有负相关性.
对于肠道微生物群代谢物,没有发现任何显著的因果关系,在欧洲验证队列中也没有发现任何关联.

结论:

*F. varium*可能会促进CHB的进展,而*V. parvula*可能会有保护作用.
肠道微生物群的代谢物似乎没有在CHB中起因作用.
需要进一步的研究来阐明肠道微生物群和CHB之间的复杂相互作用.

Introduction to the Human Microbiota

Introduction to the Human Microbiota

Microorganisms colonize various regions of the human body, including the mouth, nasal passages, throat, stomach, intestines, urogenital tract, and skin. The total number of microbial cells is estimated to range from 10¹³ to 10¹⁴—comparable to, or exceeding, the number of human somatic cells. This host–microbiome relationship has led to the conceptualization of humans as supraorganisms, wherein microbial communities perform vital roles in development, immunity, and disease...

Dysbiosis of the Gut Microbiota

Dysbiosis of the Gut Microbiota

The human gut microbiome includes a diverse array of microbial species, including beneficial commensals and opportunistic pathogens, which interact to support host health. These microbes contribute to essential functions such as nutrient metabolism, immune system modulation, and maintenance of intestinal barrier integrity. However, disruptions to this equilibrium—referred to as dysbiosis—can have widespread physiological consequences.Dysbiosis is often characterized by reduced microbial...

Microbiota Modulation by Antibiotics

Microbiota Modulation by Antibiotics

Antibiotics have revolutionized modern medicine by saving countless lives from bacterial infections. However, their widespread use has inadvertently harmed the delicate balance of the human gut microbiota. The gut microbiota, a complex community of bacteria, archaea, viruses, and fungi, plays a vital role in regulating metabolism, immune responses, and maintaining intestinal health. Antibiotics, especially broad-spectrum types, disrupt this ecosystem by eradicating both harmful and beneficial...

Hepatitis

Hepatitis

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...
