OMEGA-SPM-DOSE 和 OMEGA-SPM-PAD:外周动脉疾病患者的专业化解介质
2021年5月4日 更新者:University of California, San Francisco
本研究的目的是了解鱼油补充剂(含有部分 omega-3 脂肪酸)对炎症的影响。
研究人员旨在确定哪种剂量的鱼油补充剂最有效。
鱼油补充剂的名称是“SPM 乳液”。

详细说明
OMEGA-SPM-DOSE 试验和 OMEGA-SPM-PAD 试验是一项试点研究的两个部分,旨在研究含有高浓度 n-3 多不饱和脂肪酸代谢物(SPM 乳液)的新型营养补充剂配方对健康志愿者和外周动脉疾病 (PAD) 患者的代谢脂质组学概况。
十名健康志愿者和十名 PAD 患者将参加第 1a 部分“OMEGA-SPM-DOSE 研究”。
然后将在 PAD 和 OA 人群(n=12)中进行一项关于 1a 阶段确定的最佳给药方式的后续、安慰剂对照、前瞻性研究,1b 阶段——“OMEGA-SPM-PAD 研究”。
具体测量将包括靶向代谢-脂质组学分析、已建立的炎症标志物以及功能性单核细胞和巨噬细胞检测。
拟议的研究有可能为营养干预在 PAD 中的作用提供重要的新见解。
