INTRODUCTION: Familial hypercholesterolemia (FH) is a frequent genetic disorder characterized by elevated LDL-cholesterol (LDL-C) and early onset of atherosclerosis. AREAS COVERED: The authors provide an overview of the pediatric FH scenario, with emphasis on the role of statins as the preferred pharmacological therapy, discussing their potential benefits, as well as adverse effects, and the remaining uncertainties about their use in this population. They also comment on other lipid-lowering therapies. EXPERT OPINION: Statin therapy is recommended after the ages of 8-10 years old for heterozygous FH patients and can reduce LDL-C by 24-50% depending on drug type and dosage. For more severe cases, higher doses and adjuvant therapies like ezetimibe may be necessary and treatment should be started at diagnosis, as is the case of homozygous FH. Statins reduce progression of subclinical vascular disease and may reduce early cardiovascular events. The available evidence indicates safety of statins in children with no apparent harms related to growth, sexual maturation, steroid hormones, glucose levels, cognitive function, or muscle and liver problems, in comparison with placebo. Newer treatments like lomitapide, PCSK9 inhibitors, bempedoic acid and evinacumab need to be adequately evaluated in pediatric FH patients with more severe dyslipidemia.
简介:家族性高胆固醇血症(FH)是一种常见的遗传性疾病,其特征为 LDL 胆固醇(LDL-C)升高和动脉粥样硬化的早期发生。
涵盖领域:作者提供了儿科 FH 情况的概述,重点介绍了他汀类药物作为首选药物治疗的作用,讨论了其潜在的益处、不良反应以及在该人群中使用的剩余不确定性。他们还评论了其他降脂治疗方法。
专家意见:对于杂合子 FH 患者,建议在 8-10 岁后开始他汀类药物治疗,具体取决于药物类型和剂量,可降低 LDL-C 达 24-50%。对于更严重的病例,可能需要更高的剂量和依折麦布等辅助治疗,并且应在诊断时开始治疗,就像纯合子 FH 一样。他汀类药物可降低亚临床血管疾病的进展,并可能减少早期心血管事件。现有证据表明,与安慰剂相比,他汀类药物在儿童中的安全性良好,与生长、性成熟、类固醇激素、血糖水平、认知功能或肌肉和肝脏问题无关。对于血脂异常更严重的儿科 FH 患者,需要对新型治疗方法(如洛美他派、PCSK9 抑制剂、贝匹莫德酸和依维莫司)进行充分评估。
