- 肠道微生物群 (GM) 和糖尿病病 (DN) 之间的联系被建议,但没有因果证明.
- 现有的证据主要来自动物研究和人体横截面研究.
研究的目的:
- 使用孟德尔随机化 (MR) 调查肠道微生物群和糖尿病病之间的潜在因果关系.
- 确定与发展DN的风险相关的特定肠道微生物种群.
主要方法:
- 利用公开可用的全基因组关联研究 (GWAS) 数据.

- 进行了对结果稳定性的留出分析和对反向因果关系的反向MR.
主要成果:
- 包括Verrucomicrobiae类和Akkermansia属在内的几种微生物种类与DN风险增加有关 (p ≤0.003).
- 其他种类如Actinobacteria类和Phylum Proteobacteria与降低DN风险 (p ≤0.045) 有关.

01:21Microbiota 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...
01:28Diabetic Nephropathy
Definition Diabetic nephropathy is a chronic kidney complication that results from prolonged hyperglycemia.Prevalence It is the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide, affecting up to half of individuals with diabetes.Pathophysiology • Sustained hyperglycemia triggers multiple hemodynamic and metabolic changes in the kidney. • Early in the disease, increased renal blood flow and glomerular hyperfiltration occur due to afferent arteriolar...
