补充omega-3可以降低患肝病的风险,包括非酒精性脂肪肝病 (NAFLD) 和酒精性肝病. 这一发现对具有遗传倾向的个体来说尤其有希望.
科学领域:
- 肝病学 肝病学是一种肝病学.
- 营养科学 营养科学
- 预防医学 预防医学
背景情况:
- 非酒精性脂肪肝病 (NAFLD) 和酒精性肝病是全球普遍存在的健康问题,没有FDA批准的治疗方法.
- 目前对NAFLD的管理策略强调生活方式的修改.
- 欧米茄-3脂肪酸在治疗慢性肝病方面表现有前途,但它们的预防作用,特别是在基因危险的个体中,仍在研究中.
研究的目的:
- 研究omega-3补充剂在预防肝病发病的潜力.
- 评估欧米茄-3摄入量与发展特定肝病的风险之间的关联,包括NAFLD和酒精性肝病.
- 探索欧米茄-3补充剂是否为特定的人口群体或具有遗传风险因素的个人提供好处.
主要方法:
- 英国生物银行的一项队列研究使用了多变量Cox比例危险模型.
- 用了11年的随访期来追踪发生的肝病.
- 该模型根据许多混因素进行了调整,包括糖尿病,心血管疾病,社会经济地位,饮食,酒精消费,体力活动和药物使用.
主要成果:
- 补充欧米茄-3与发生性肝病的风险显著降低有关 (HR = 0.716,p = 7.6 × 10-9).
- 在酒精性肝病 (HR = 0.559,p = 4.3 × 10−3),肝衰竭 (HR = 0.548,p = 1.2 × 10−2) 和非酒精性肝病 (HR = 0.784,p = 1.0 × 10−2) 中观察到保护作用.
- 在肝脏MRI (HR = 0.846,p = 1.1 × 10−4) 的子组中证实了NAFLD风险的降低,对女性和PNPLA3 rs738409变体的携带者有显著的好处.
结论:
- 补充omega-3可能有助于减少各种肝脏疾病的发生率.
- 这些发现表明了个性化治疗方法的潜力,特别是在代谢性肝病风险较高的人群中.
- 需要进一步的临床试验,以确定omega-3补充剂作为肝脏疾病的推预防措施.

Metabolic Regulation:
The liver is the central organ involved in regulating blood composition. It stabilizes blood glucose levels, maintaining them within the range of 70–110 mg/dL. When these levels drop, the liver breaks down glycogen reserves and releases glucose into the bloodstream. It can...
