概括
患有非增殖性糖尿病视网膜病变 (NPDR) 的患者乳酸脱酶 (LDH) 水平较高,与一年内发展为增殖性糖尿病视网膜病变 (PDR) 和其并发症的风险增加有关.
科学领域:
- 眼科医生 眼科 眼科
- 内分泌学 在内分泌学.
- 生物化学 生物化学
背景情况:
- 糖尿病视网膜病变 (DR) 是导致失明的主要原因,从非增殖性 (NPDR) 到增殖性 (PDR) 阶段的进展会带来严重的视力威胁风险.
- 系统性乳酸脱酶 (LDH) 是一种涉及各种病理过程的酶,但其在DR进展中的具体作用尚未完全理解.
研究的目的:
- 调查诊断为NPDR的患者的基线系统LDH水平与他们随后1年进展到PDR及其并发症的风险之间的关联.
- 为了确定LDH水平与PDR进展风险之间是否存在剂量依赖的关系.
主要方法:
- 使用TriNetX美国协作网络进行了一项回顾性,倾向匹配的队列研究.
- 患有2型糖尿病和新发性NPDR的患者根据诊断后6个月内的测量,被分为低 (<200U/L),中度 (201-280U/L) 和高 (≥281U/L) LDH组.
- 主要结局包括PDR,1年绝对风险和风险比率,拉力视网膜脱落 (TRD) 和玻璃体出血 (VH).
主要成果:
- 与低LDH组相比,中度LDH组的患者对PDR (3.93%对2.96%),TRD (1.35%对0.99%) 和VH (4.38%对3.51%) 的1年风险更高.
- 与低LDH组相比,高LDH组的PDR (3.66%vs. 3.00%),TRD (1.27%vs. 0.96%) 和VH (1.27%vs. 0.96%) 的1年风险增加.
- 观察到系统性LDH水平升高与PDR进展和并发症风险增加之间存在一致的,剂量依赖的关系.
结论:
- 较高的全身LDH水平与进展为增殖性糖尿病视网膜病变 (PDR) 和相关并发症的风险显著增加有关.
- 这些发现表明,LDH可能作为预测2型糖尿病患者DR进展的潜在生物标志物.
- 需要进一步的研究来探索将LDH与DR病原体联系起来的潜在机制,并评估针对LDH的潜在治疗干预措施.

Type II Diabetes Mellitus III: Clinical Manifestations and Diagnosis
Type 2 diabetes mellitus develops gradually and is often asymptomatic in early stages.Clinical ManifestationsWhen symptoms appear, they include fatigue, blurred vision, pruritus, delayed wound healing, and recurrent infections, particularly candidal infections. Peripheral neuropathy may present as numbness or tingling in the extremities. Classic hyperglycemia symptoms—polyuria, polydipsia, and polyphagia—are less common. Most patients are overweight and frequently have associated hypertension...
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...
