概括
儿童的家族性高胆固醇血症 (FH) 需要早期的药物治疗,因为仅靠饮食是无效的. 同胞性FH (HoFH) 较难管理,当药物失败时,肝移植是可行的选择.
科学领域:
- 儿科内分泌学 儿科内分泌学
- 心血管遗传学 心血管遗传学
- 代谢障碍 代谢障碍 代谢障碍
背景情况:
- 家族性高胆固醇血症 (FH) 是一种遗传性疾病,从出生开始就导致极高的LDL胆固醇水平.
- 早期诊断和治疗对于预防患有FH的儿童早发性心血管疾病至关重要.
研究的目的:
- 分析儿科FH的临床特征.
- 评估儿童FH亚型的诊断方法和治疗疗效.
- 为个性化治疗策略提供基础.
主要方法:
- 一个案例系列研究分析了24名被诊断患有FH的儿童的临床数据.
- 根据基因测试,儿童被分为同卵性FH (HoFH) 和异卵性FH (HeFH) 组.
- 使用统计分析对血脂水平,治疗反应和临床结果进行了比较.
主要成果:
- 在所有24名儿童中,基因检测确定了LDLR或APOB基因变异,其中有5例HoFH和19例HeFH病例.
- 桑托马在25%的儿童中存在,在HoFH中更常见.
- 仅通过饮食控制是不够的;在12名儿童中,他类药物和/或ezetimibe改善了LDL-C,但HoFH患者对这些药物反应有限. 一名HoFH患者在肝移植后实现了正常的LDL-C.
结论:
- 桑托马是特征性的,但并不总是存在于儿科FH,特别是HeFH.
- 家庭病史和遗传检测对于诊断儿童的FH至关重要.
- 建议在儿童中早期开始药物治疗,因为饮食干预在很大程度上是无效的. 肝移植是严重的HoFH病例中不对药物反应的潜在选择.

Cholesterol: Significance and Regulation
1.2K
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
1.8K
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

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...

Chronic Kidney Disease II: Clinical Manifestations

Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Inborn Errors of Metabolism
697
Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...

Blood Studies for Cardiovascular System III: Serum Lipid Profile

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...
