概括
升高的脂蛋白 (a) [Lp (a) ]显著影响高胆固醇血症儿童的胆固醇水平. 早期对Lp (a) 的评估对于管理这些年轻患者心血管疾病风险至关重要.
科学领域:
- 儿科 儿科 儿科
- 心脏病学 心脏病学
- 遗传学 是一个遗传学.
背景情况:
- 脂蛋白 (Lp) 是心血管疾病 (CVD) 的关键遗传风险因素.
- 由于粒子相似性,极高的Lp(a) 水平可以提高低密度脂蛋白胆固醇 (LDL-C).
- 在儿科高胆固醇血症中Lp (a) 的作用尚不清楚.
研究的目的:
- 研究Lp (a) 对高胆固醇血症儿童的LDL-C的影响.
- 在儿科高胆固醇血症队列中确定升高Lp (a) 的患病率.
- 评估Lp (a) 对受影响儿童的整体LDL-C水平的贡献.
主要方法:
- 该研究包括1418名通过查确定的高胆固醇血症儿童.
- 参与者被分为明确的FH,可能的FH和明确的非FH组.
- 分析的重点是Lp(a) 水平及其与LDL-C和Apolipoprotein B.的相关性.
主要成果:
- 在25.1%的确定的FH病例和34.9%的可能的FH病例中发现Lp (a) 升高 (>30 mg/dL).
- Lp(a) 对LDL-C (10.3%的变化率) 和阿波蛋白B水平有显著的贡献.
- 即使在Lp(a) 调整后,LDL-C的升高在绝大多数确定的FH (88.4%) 和很大一部分可能的FH (30.4%) 儿童中仍然存在.
结论:
- 大约四分之一患有FH的儿童和三分之一患有多原性高胆固醇血症的儿童表现出升高的Lp.
- 升高的Lp (a) 导致这些儿科群体的LDL-C和Apolipoprotein B升高.
- 对这些儿童来说,早期识别和管理可修改的风险因素,如升高的LDL-C和肥胖是必不可少的.

Blood Studies for Cardiovascular System III: Serum Lipid Profile
698
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
1.7K
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
2.4K
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...

Lipid-Lowering Drugs: Statins and Miscellaneous Agents
1.6K
Hyperlipidemia, a medical condition often referred to as high cholesterol, is characterized by abnormally elevated levels of lipids in the bloodstream. When present in excess, these lipids, specifically cholesterol and triglycerides, can lead to serious health complications, often involving cardiovascular diseases. Illnesses like atherosclerosis, heart attacks, and pancreatitis have all been linked to untreated hyperlipidemia. This means controlling and regulating cholesterol and triglyceride...

Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...

Lipid-derived Compounds in the Human Body
7.2K
Fats and lipids are crucial components in the human body. Some lipid-derived compounds, such as fat-soluble vitamins, eicosanoids, lipoproteins, and glycolipids, also play unique roles to support various biological processes .
Fat-soluble Vitamins
Fat-soluble vitamins, including vitamins A, D, E, and K, are required in minimal quantities, but their deficiencies can lead to severely abnormal physiological conditions. For example, vitamin A deficiency can cause night blindness, dry skin,...
