概括
糖尿病视网膜病变 (DR) 患者的肠道细菌组成不同. 在肠道微生物群中较低水平的特定细菌,如Butyricicoccus和酸盐,可能预测糖尿病患者的DR发展.
科学领域:
- 微生物组研究的研究.
- 眼科医生 眼科 眼科
- 代谢性疾病是一种代谢性疾病.
背景情况:
- 肠道微生物群被认为是糖尿病及其并发症的危险因素.
- 糖尿病视网膜病变 (DR) 是糖尿病的一个显著的微血管并发症.
- 了解肠道微生物组在DR中的作用对于早期检测和干预至关重要.
研究的目的:
- 调查肠道微生物组组成和糖尿病视网膜病变 (DR) 之间的关联.
- 为了确定可预测糖尿病患者DR发展的微生物特征.
- 探索肠道细菌,代谢物和DR之间的关系.
主要方法:
- 对99名糖尿病患者进行横截面研究,以确定微生物特征.
- 在2年内对62名糖尿病患者进行前性队列研究,以评估预测价值.
- 使用了肠道微生物组分析,机器学习 (随机森林) 和代谢物分析.
主要成果:
- 在DR患者中确定了明显的肠道微生物特征,包括减少Butyricicoccus和Ruminococcus扭矩组,以及升调的甲基生成.
- DR患者的血短链脂肪酸含量较低,包括乙酸.
- 一个由微生物属和基因组成的小组有效地区分了DR病例,并在前性研究中预测了DR发病率.
- 减少的Butyricicoccus和血乙酸被前性地与增加的DR易感性相关.
结论:
- 肠道微生物组的改变与糖尿病视网膜病变有关.
- 特定的微生物种群和代谢物,如Butyricicoccus和酸盐,显示出作为DR风险早期生物标志物的潜力.
- 这些发现支持开发针对性的基于微生物组的干预措施,以管理糖尿病并发症.

Diabetic Retinopathy
DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
Diabetic 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...
