血脂异常的基本概念和分类是什么？ 高血脂专题：新通路药物兴起，市场潜力有望爆发 20251116 摘要 中国高血脂异常患者超过 4 亿，治疗率低，现有药物如他汀类疗效存在 瓶颈，PCSK9 抑制剂价格昂贵且需注射，限制了临床应用，市场存在巨 大未满足需求。 小核酸技术平台正拓展至 LPA、APOC3 等新靶点，口服 PCSK9 抑制剂 （如默沙东产品）临床结果显示疗效与注射剂相当，有望提高患者接受 度，预计销售峰值超 50 亿美元。 目前降血脂药物主要通过减少胆固醇和三酰甘油合成、抑制外源性胆固 醇吸收、促进脂质清除三个通路调节，他汀类药物存在疗效局限性，依 折麦布需联合他汀使用。 PCSK9 抑制剂（如依洛尤单抗）显著降低 LDL 水平并减少心血管事件， 默沙东口服环肽在 24 周内可使 LDL 下降 60%，小核酸药物（如英克司 兰）销售额快速增长。 针对高甘油三酯血症，NANGPTL3 和 APOC3 是新的治疗靶点，小核酸 产品临床数据表现良好。LPA 被认为是独立的心血管疾病风险因素，但 缺乏特效药。 Q&A 近年来降血脂市场有哪些变化和创新趋势？ 近年来，降血脂市场迎来了显著的变革，特别是在小核酸 ...

Core Insights - The article discusses the relationship between maternal cholesterol levels during pregnancy and the risk of congenital heart defects (CHD) in offspring, highlighting the importance of cholesterol in fetal development [2][10]. Group 1: Research Findings - A study published in "Signal Transduction and Targeted Therapy" indicates that low maternal cholesterol levels during pregnancy are significantly associated with an increased risk of CHD in offspring, particularly during mid to late pregnancy [3][6]. - The research involved a cohort of 5,041 family trios and found a notable correlation between maternal low cholesterol levels and the incidence of CHD in children [6]. - The study utilized cholesterol-lowering drugs, ezetimibe and atorvastatin, on pregnant mice, which resulted in a significant increase in the incidence of CHD in their offspring [8]. Group 2: Genetic Insights - Whole-genome sequencing of 103 children with CHD identified a pathogenic mutation in the CYP51A1 gene, which affects cholesterol synthesis and disrupts Hedgehog (Hh) signaling, leading to CHD [8]. - The study created a Cyp51 I383V gene knock-in mouse model to further investigate the link between cholesterol synthesis and CHD, confirming that dietary cholesterol supplementation could significantly reduce the risk of CHD in offspring of mutant mothers [8][10]. Group 3: Implications for Maternal Health - The findings suggest that maternal cholesterol supplementation during pregnancy could be an effective strategy to lower the risk of CHD in children, emphasizing the need for further research in this area [10].

Summary of Key Points from Conference Call Records Industry Overview - The conference call discusses advancements in small RNA (siRNA) drug development, particularly in the context of cardiovascular disease treatment and metabolic disorders [1][3][12]. Core Insights and Arguments - **Inclisiran as a Leading siRNA Drug**: Inclisiran demonstrates significant lipid-lowering effects similar to vaccines, requiring administration only twice a year, enhancing patient compliance [1][3]. - **Mechanism of Action**: siRNA not only clears existing target proteins but also inhibits the future production of these proteins, such as PCSK9, providing a more durable treatment effect compared to monoclonal antibodies [1][4][6]. - **Safety and Efficacy**: siRNA is considered safer than gene editing techniques as it does not alter DNA, thus minimizing risks associated with off-target effects and ethical concerns [5][6]. - **Sales Growth of Novartis' PCSK9 siRNA Product**: The product has seen rapid sales growth due to its ability to target liver cells and provide long-lasting effects, with injection intervals of up to six months or even a year [6][12]. - **Challenges in siRNA Delivery**: Effective delivery remains a significant challenge, with the Galenic system being the most mature and clinically validated for liver-targeted delivery [7][19]. - **Potential in Metabolic Weight Loss**: siRNA technology shows promise in metabolic weight loss, but further research is needed to confirm its effectiveness [8][20]. Additional Important Content - **Targeting Cholesterol and Triglycerides**: ANGPTL4 and APOC3 are highlighted as key targets for cholesterol and triglyceride management, respectively, with a focus on achieving cardiovascular benefits [8][10]. - **LPA and LDL in Cardiovascular Risk**: High levels of LPA can indicate cardiovascular risk even when LDL levels are low, suggesting that both should be targeted for optimal cardiovascular health [10]. - **Combination Therapy Potential**: Combining siRNA with statins or other oral medications can significantly enhance lipid-lowering effects, but requires careful monitoring of biochemical indicators for safety [14][15]. - **Long-term Patient Management**: Regular monitoring of biochemical markers is crucial for patients on long-term lipid-lowering therapies, especially in populations with higher intolerance to statins [15][16]. - **Future of siRNA in Clinical Practice**: siRNA drugs could potentially become first-line treatments if they demonstrate sufficient efficacy and safety through large-scale clinical trials [12][13]. Conclusion - The siRNA technology landscape is evolving, with significant potential in treating cardiovascular diseases and metabolic disorders. However, challenges in delivery systems and the need for extensive clinical validation remain critical for its future success in clinical applications [17][23].
