概括
低高密度脂蛋白胆固醇 (HDL-C) 水平和高的末期肝病模型 (MELD) 评分预测明显肝脑病变 (OHE) 患者的死亡率. 这种组合有助于识别高风险个体,以便及时介入.
科学领域:
- 肝病学 肝病学是一种肝病学.
- 脂质代谢 脂质代谢是什么
- 预测生物标志物 预测生物标志物
背景情况:
- 突发性肝脑病变 (OHE) 是肝硬化的一种严重并发症.
- 在OHE患者中,脂质和脂蛋白代谢发生变化.
研究的目的:
- 评估OHE患者高密度脂蛋白胆固醇 (HDL-C) 水平与无移植 (TF) 死亡率之间的相关性.
- 评估HDL-C的预后值与末期肝病模型 (MELD) 评分相比.
主要方法:
- 用多变量考克斯回归分析来确定死亡率的独立预测因素.
- 计算了接收器运行特征曲线 (AUC) 下的面积,以评估预后值.
- 患者被分为训练 (n=821) 和验证 (n=480) 组.
主要成果:
- HDL-C显示出良好的预后值 (AUC在1年:0.745),与MELD得分 (AUC在1年:0.788) 相比.
- 最佳值被确定为HDL-C<0.5 mmol/L和MELD得分>17.
- 与低风险组相比,高风险组 (HDL-C < 0.5 mmol/L和MELD ≥ 17) 的1年TF死亡率显著更高 (51.5%的培训,48.2%的验证),低风险组 (7.5%的培训,10.1%的验证).
结论:
- 较低的HDL-C水平 (<0.5 mmol/L) 与高的MELD得分 (> 17) 相结合,有效地识别高风险OHE患者.
- 这种风险分层可以指导及时的治疗干预,以改善患者的治疗结果.

Understanding serum lipids is crucial for maintaining cardiovascular health and preventing heart disease and stroke.
Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...

Cholesterol: Significance and Regulation
520
Although not a source of energy, cholesterol plays a significant role as a foundational structure for bile salts, steroid hormones, and vitamin D, as well as being a crucial component of plasma membranes. Approximately 15% of blood cholesterol is derived from our diet, with the remainder synthesized from acetyl CoA by the liver and intestines. Cholesterol is eliminated from the body through its conversion into bile salts, which are eventually discarded in the feces.

Lipids: Dietary Sources and Requirements
708
Lipids are an essential component of a balanced human diet. Triglycerides, which make up the majority of dietary lipids, are found in both saturated fats—commonly present in meat, dairy products, and certain tropical plants like coconut, and hydrogenated oils such as margarine and baking shortenings (trans fats)—and unsaturated fats, which are abundant in seeds, nuts, olive oil, and most vegetable oils. The main sources of cholesterol include egg yolks, various meats and organ...
