基因編輯療法YOLT-101單次輸注可降低壞膽固醇52.3% 效果維持半年

Quick Look

中國上海交通大學醫學院附屬仁濟醫院與尧唐生物合作的人體早期試驗顯示,基因編輯療法YOLT-101單次靜脈輸注後,最高劑量組患者24週後LDL-C平均下降52.3%,半年追蹤期間降幅維持,未見嚴重不良事件。

AI-generated summary

Why It Matters

遺傳性高膽固醇血症患者體內LDL-C長期偏高,容易提早出現動脈粥狀硬化與心血管疾病,現有降血脂藥物需長期服用。

〔編譯陳成良/綜合報導〕高血脂患者未來有機會不用天天服藥嗎?一項最新人體早期試驗發現,新型基因編輯療法只需單次靜脈輸注,接受最高劑量治療的患者,24週後血液中的「壞膽固醇」平均下降52.3%,降幅在半年追蹤期間仍維持。

這項研究結果發表於醫學期刊《Nature Medicine》。研究由中國上海交通大學醫學院附屬仁濟醫院與尧唐生物(YolTech Therapeutics)合作進行,針對血脂控制不佳的遺傳性高膽固醇血症患者測試YOLT-101。這類患者體內低密度脂蛋白膽固醇(LDL-C)長期偏高,容易提早出現動脈粥狀硬化與心血管疾病。

請繼續往下閱讀...

研究測試名為「YOLT-101」的體內基因編輯療法,利用脂質奈米顆粒把基因編輯工具送進肝臟細胞,針對「PCSK9」基因進行編輯。PCSK9會妨礙肝臟清除血液中的壞膽固醇,研究團隊希望透過關閉這個基因,讓肝臟提高清除膽固醇的能力,進而讓一次治療維持較長時間。

試驗共納入6名患者,分別接受3種不同劑量的單次靜脈輸注。結果顯示,最高劑量組3名患者在第4週時,壞膽固醇平均下降48.9%,到了第24週降幅達52.3%。研究同時發現,PCSK9濃度也隨劑量增加而下降,顯示基因編輯確實產生預期的生物作用。

這項研究的重點並不是單純把膽固醇短暫壓低,而是測試能否透過一次基因編輯,讓降脂效果持續更久。從24週結果來看,最高劑量組的降幅並未明顯消退,但目前仍無法知道效果能維持幾年。

僅6人第1期試驗 還不能取代現有降血脂藥

安全性方面,研究期間沒有出現3級以上不良事件,較常見反應包括短暫輸注相關症狀與肝酵素升高。研究團隊認為目前結果支持進一步開發,但這項療法仍處於早期人體試驗階段。

Hong Yongxiang advises kidney friends: adding black coffee with olive oil can protect the kidneys and avoid adding sugary creamer.

Director of Hong Yongxiang Clinic pointed out that Mr. Chen, a patient with chronic renal failure, drank coffee with sugar and creamer every day, which led to high blood phosphorus and declining kidney function. However, he emphasized that coffee itself does not damage the kidneys, and the key is how he drinks it. It is recommended to choose sugar-free black coffee, avoid creamer and refined sugar, and mix it with an appropriate amount of extra cold-pressed virgin olive oil at high speed to reduce health burden and protect the kidneys.

Study finds people with insufficient muscle mass are at higher risk of infection and sepsis

A research team from Xiangya Hospital of Central South University in China analyzed the data of more than 458,000 adults in the British Biobank and found that those with pre-sarcopenia and sarcopenia have an increased risk of infection, especially with respiratory infections and sepsis. The study points out that regular strength training can help maintain muscle health, but it cannot prove that muscle loss directly causes an increase in infections.

Even after eight hours of sleep, you are still tired? Beware of "Chronic Fatigue Syndrome"

If you have unexplained severe fatigue, memory loss, and muscle aches that last for more than six months, and there are no abnormalities in hospital examinations, you may be suffering from chronic fatigue syndrome. Chen Min, an expert from the Jiangsu Provincial Hospital of Traditional Chinese Medicine, suggested systematic conditioning of the five internal organs, qi and blood, through TCM syndrome differentiation and lifestyle adjustment.

To manage blood lipids, the elderly should know how to eat "good fats" | Enjoy your silver age and protect your health

The article points out that controlling blood lipids requires not only reducing fat intake, but also paying attention to the endogenous fat converted from polished rice and white flour. The elderly should choose oils rich in monounsaturated fatty acids and omega-3 polyunsaturated fatty acids, such as olive oil, tea seed oil, etc., eat egg yolks in moderation to obtain the benefits of lecithin, and replace some refined white rice noodles with whole grains such as oats and buckwheat to increase soluble dietary fiber to absorb cholesterol and promote excretion.
