      [Abstract] Objective To Investigate the effect of the GLP-1 receptor agonist on patients with type 2 diabetes mellitus (T2DM) between the short-term and long-term metabolic control. Methods 120 patients with T2DM treated with Exenatide in Qingdao Endocrinology Diabetes Hospital from 2010 to 2013 were divided into two groups due to the term of drug use. Patients in group A (n=58) applied Exenatide not less than 24 weeks, while those in goup B (n=62) more than 24 weeks. Indicates included body weight (before and after the treatment), WC, HC, FBG, P2Hbg, HbA1C, TG, TC, LDL, HDL, SBP, DBP, BMI, WSR, WHR, BMD, and body fat content. Results The body weight, BMI and the body fat content in two groups were both decreased than that before treatment, which had no significant difference in the comparison between groups (P>0.05); WC, WSR, FBG, P2hBG, HbA1C, SBP, DBP in two groups were both decreased than that before treatment, which had statistically significant difference in the comparison between the two groups (P<0.05).TG, TC, LDL, HDL in two groups had no statistically different neither before nor after treatment (P>0.05). Neither the gastrointestinal adverse reaction nor the rate of hypoglycemia in the two groups had no statistically different in the comparison between groups (P>0.05). Conclusion The better clinical effect of GLP-1 receptor agonists for T2DM lies in long-term application, which can also decrease the risk of the gastrointestinal reactions and hypoglycemia, redistribute the body fat and improve abdominal obesity and insulin resistance.

      艾塞那肽是一種胰高糖素樣肽-1(GLP-1)類(lèi)似物,通過(guò)激動(dòng)GLP-1受體,刺激葡萄糖依賴的胰島素分泌[1-2],在臨床中已大量應(yīng)用,主要作用是控制血糖、減輕體重、改善胰島素抵抗。然而,艾塞那肽使用時(shí)間尚無(wú)定論,目前尚未有研究探討短期與長(zhǎng)期應(yīng)用是否對(duì)重要代謝指標(biāo)產(chǎn)生不同的影響,本研究通過(guò)對(duì)120例T2DM病例的分析,探討GLP-1受體激動(dòng)劑短期與長(zhǎng)期應(yīng)用對(duì)重要代謝指標(biāo)控制的影響,指導(dǎo)GLP-1受體激動(dòng)劑臨床應(yīng)用時(shí)間,以期達(dá)最佳治療效果。

      1?資料與方法

      1.1?一般資料

      選取2010~2013年于青島內(nèi)分泌糖尿病醫(yī)院應(yīng)用艾塞那肽(Baxter Pharmaceutical Solutions LLC,H20090381/H20090382)治療的T2DM患者120例(男65例,女55例),平均年齡(48.75±6.79)歲。根據(jù)艾塞那肽使用時(shí)間分為兩組:短期治療組A組 (使用時(shí)間≤24周,n=58),長(zhǎng)期治療組B組 (使用時(shí)間>24周,n=62)。兩組性別、血糖、血壓、病程等差異無(wú)統(tǒng)計(jì)學(xué)意義(P>0.05)。

      1.2?治療方法

      兩組均予以艾塞那肽治療,起始劑量5μg,每日2次,在早餐和晚餐前30min內(nèi)皮下注射,根據(jù)臨床應(yīng)答,在治療1個(gè)月后劑量為10μg,每日2次。

      1.3?觀察指標(biāo)

      觀察兩組治療后體重、WC、HC、FBG、P2hBG、HbA1C、TG、TC、LDL、HDL、SBP、DBP、全身脂肪含量的變化,同時(shí)比較兩組胃腸道不良反應(yīng)及低血糖發(fā)生率。

      兩組體重、BMI、全身脂肪含量均較治療前下降,但組間差異無(wú)統(tǒng)計(jì)學(xué)意義(P>0.05);兩組WC、WSR、FBG、P2hBG、HbA1C、SBP、DBP均較治療前下降,組間比較差異有統(tǒng)計(jì)學(xué)意義(P<0.05)。兩組TG、TC、LDL、HDL較治療前后及組間差異無(wú)統(tǒng)計(jì)學(xué)意義(P>0.05)。結(jié)果見(jiàn)表1。

      3?討論

      有相關(guān)報(bào)道顯示,中國(guó)已經(jīng)成為世界肥胖人數(shù)最多的國(guó)家之一,而肥胖是導(dǎo)致T2DM的危險(xiǎn)因素[3-4]。亦有研究[5]表明,肥胖患者存在高胰島素血癥及胰島素敏感性的下降, 認(rèn)為腹內(nèi)脂肪增加是胰島素抵抗的主要原因。因此,減輕體重、改善胰島素抵抗為治療2型糖尿病的重要作用靶點(diǎn)。艾塞那肽是一種39個(gè)氨基酸組成的胰高糖素樣肽類(lèi)似物,通過(guò)葡萄糖依賴性的促胰島素釋放和抑制胰高糖素釋放而調(diào)節(jié)血糖,并具有延緩胃排空、抑制食欲、減輕體重、改善胰島素抵抗以及保護(hù)胰島細(xì)胞功能等作用[6-7]。

      本研究顯示,長(zhǎng)期應(yīng)用艾塞那肽可以更有效的控制血糖及糖化血紅蛋白達(dá)標(biāo),且不增加胃腸道反應(yīng)及低血糖發(fā)生風(fēng)險(xiǎn),無(wú)嚴(yán)重不良事件發(fā)生。艾塞那肽亦具有減輕體重的作用,但隨著用藥時(shí)間的延長(zhǎng),體重、BMI及全身脂肪含量未得到進(jìn)一步改善,本研究有一定的局限性,其是否可以持續(xù)性的減輕體重的作用有待觀察[8]。但本研究可見(jiàn)腰圍明顯下降,結(jié)果示長(zhǎng)期應(yīng)用艾塞那肽雖不能進(jìn)一步減輕體重,但可以明顯的減輕腰圍,使體脂得到重新分布,改善腹型肥胖及胰島素抵抗[9-10]。

      艾塞那肽具有改善T2DM患者血壓的作用,與其通過(guò)抑制腎臟對(duì)Na+的重吸收或抑制腎臟血管緊張素誘導(dǎo)的細(xì)胞外信號(hào)調(diào)節(jié)激酶的磷酸化,從而促進(jìn)腎鈉排泄與利尿,同時(shí)通過(guò)對(duì)血管內(nèi)皮的直接作用,增強(qiáng)NO依賴的血管擴(kuò)張有關(guān)[11-12]。本研究表明,兩組治療后SBP及DBP均有一定程度下降[13],且與藥物使用時(shí)間成正比。但本研究中未見(jiàn)血脂改善,與其他臨床試驗(yàn)結(jié)果不一致[14],可能與研究樣本量較少,且用藥前血脂水平大致在正常水平有關(guān)。

      本研究觀察例數(shù)較少,有一定的局限性,長(zhǎng)期應(yīng)用艾塞那肽的療效有待進(jìn)一步研究。
