Circulation:科學(xué)家研制出降膽固醇新藥 已有6人參與

摘要:據(jù)英國(guó)《每日郵報(bào)》近日?qǐng)?bào)道,澳大利亞科學(xué)家發(fā)現(xiàn),他們正在研制的降膽固醇新藥Torcetrapib與他汀類藥物(Statin)一起服用,可以顯著改進(jìn)2型糖尿病患者的血糖控制情況。 Torcetrapib旨在提高“好”膽固醇的濃度,其能穩(wěn)定血糖水平,減少心臟病和糖尿病發(fā)作的風(fēng)險(xiǎn)。好膽固醇非常重要,因?yàn)樗軠p慢動(dòng)脈硬化,降低心臟疾病發(fā)作風(fēng)險(xiǎn)。 悉尼大學(xué)心臟病研究所的主任、醫(yī)學(xué)教授菲利普·巴特領(lǐng)導(dǎo)的科研團(tuán)隊(duì)對(duì)1.5萬(wàn)名年齡介于45歲到75歲之間的糖尿病患者進(jìn)行了研究,這些人都有心臟病發(fā)作、中風(fēng)、胸痛、周圍血管性疾病等病史。 早期實(shí)驗(yàn)結(jié)果顯示:7000名2型糖尿病患者的血糖控制程度都有所好轉(zhuǎn),最新研究發(fā)表在美國(guó)心臟協(xié)會(huì)的雜志《循環(huán)》(Circulation)上。 約有250萬(wàn)名英國(guó)人罹患2型糖尿病,超重和缺乏鍛煉都會(huì)引起糖尿病。糖尿病會(huì)增加人們罹患心臟病、中風(fēng)和其他心臟疾病的風(fēng)險(xiǎn)。很多患者使用能降低膽固醇水平的他汀類藥物來(lái)進(jìn)行治療。巴特補(bǔ)充道,這個(gè)實(shí)驗(yàn)性的藥物在治療糖尿病時(shí),并不像其他藥物一樣有效,但是,當(dāng)患者服用大劑量的他汀類藥物后,這種藥物能預(yù)防糖尿病病情的惡化。 科學(xué)家也正在研發(fā)其他兩個(gè)類似的藥物,達(dá)塞曲匹(Dalcetrapib)和anaecetrapib。而英國(guó)心臟基金會(huì)的新聞發(fā)言人表示,現(xiàn)在要想說(shuō)出這兩種新藥是否有效還為時(shí)過(guò)早。 生物探索推薦英文論文摘要: Effect of Torcetrapib on Glucose, Insulin, and Hemoglobin A1c in Subjects in the Investigation of Lipid Level Management to Understand its Impact in Atherosclerotic Events (ILLUMINATE) Trial Abstract: Background—High-density lipoproteins have antidiabetic properties in vitro. Furthermore, elevated high-density lipoprotein levels accompanying a genetic deficiency of cholesteryl ester transfer protein are associated with decreased levels of plasma glucose. We now investigate effects on glucose homeostasis of inhibiting cholesteryl ester transfer protein with torcetrapib. Methods and Results—A post hoc analysis of the Investigation of Lipid Level Management to Understand its Impact in Atherosclerotic Events (ILLUMINATE) trial was conducted to investigate effects of the cholesteryl ester transfer protein inhibitor torcetrapib on glycemic control in the 6661 diabetic patients in the trial. At baseline, there were no differences between the 2 treatment arms with respect to plasma glucose, insulin, hemoglobin A1c, or the homeostasis model assessment of insulin resistance. After 3 months, the diabetic subjects taking the combination of torcetrapib plus atorvastatin had plasma glucose levels 0.34 mmol/L lower (P<0.0001) and insulin levels 11.7 μU/mL lower (P<0.0001) than in those receiving atorvastatin alone. Homeostasis model assessment of insulin resistance values decreased from 49.1 to 47.3 (P<0.0001) in the torcetrapib/atorvastatin arm compared with an increase in homeostasis model assessment of insulin resistance in the atorvastatin arm. At the 6-month time point, the mean hemoglobin A1c level in the atorvastatin arm was 7.29% compared with 7.06% in the torcetrapib/atorvastatin arm (P<0.0001). These effects of torcetrapib remained apparent for up to 12 months. Torcetrapib also lowered both glucose and insulin levels in the participants without diabetes mellitus, although the effects were not as great as in those with diabetes mellitus. Conclusions—Treatment with torcetrapib improves glycemic control in atorvastatin-treated patients with type 2 diabetes mellitus. 看到這么好的文章,當(dāng)然要轉(zhuǎn)過(guò)來(lái)了。完整資訊地址:http://www.biodiscover.com/news/pharmatrends/article/91337.html |
