【摘要】目的了解新疆維吾爾自治區(qū)伊犁州HIV感染者早期高效抗反轉(zhuǎn)錄病毒治療后T淋巴細(xì)胞水平的變化情況及相關(guān)影響因素。方法選取伊犁州2008年1月—2012年12月首次參加抗病毒治療的HIV感染者(基線T淋巴細(xì)胞計數(shù)>350個/μl)為研究對象,收集其基線情況及治療后各隨訪時點(diǎn)(6個月、12個月、18個月、24個月)的相關(guān)資料并進(jìn)行統(tǒng)計分析。結(jié)果共收集311例HIV感染者信息,基線T淋巴細(xì)胞計數(shù)的M(P25,P75)為440(391,525)個/μl;治療6個月與基線、12個月與6個月、18個月與12個月的T淋巴細(xì)胞計數(shù)比較,差異均有統(tǒng)計學(xué)意義(Z=-6.6,P<0.01;Z=-3.6,P<0.01;Z=-2.5,P=0.01),6、8、12、24個月時的T淋巴細(xì)胞計數(shù)與基線相比分別上升了84、123、143、140個/μl;T淋巴細(xì)胞計數(shù)有隨時間變化的趨勢(F=31.56,P<0.01),不同基線T淋巴細(xì)胞分組治療后T淋巴細(xì)胞計數(shù)差異有統(tǒng)計學(xué)意義(F=20.54,P<0.01),>500個/μl組治療后T淋巴細(xì)胞計數(shù)增長量低于351~500個/μl組。結(jié)論早期抗病毒治療后T淋巴細(xì)胞計數(shù)在前6個月升高幅度較大,隨后升高的幅度逐漸緩慢趨于穩(wěn)定;基線T淋巴細(xì)胞計數(shù)越高,免疫功能恢復(fù)越好。
【關(guān)鍵詞】早期抗病毒治療;T淋巴細(xì)胞;獲得性免疫缺陷綜合征
本研究創(chuàng)新點(diǎn):
(1)本研究調(diào)查現(xiàn)場選擇在新疆維吾爾自治區(qū)伊犁州,81.4%的HIV感染者為維吾爾族,使得研究對象具有較好的區(qū)域代表性。
(2) 早期抗病毒治療已在我國部分地區(qū)開展,但相關(guān)研究仍較少,本研究旨在對早期抗病毒治療效果進(jìn)行評價,為早期治療提供一定的依據(jù)。

【Abstract】ObjectiveTo analyze the variation ofT lymphocyte cell counts after early initiation of highly active antiretroviral therapy(HAART) among HIV- infected patients in Yili,Xinjiang and its influencing factors.MethodsThe research subjects were HIV- infected patients withT lymphocyte count >350 cell/μl who received HAART for the first time in Yili between Jan 2008 to Dec 2012,we collected baseline and follow-up(6 month,12 month,18 month,24 month) data,which were analyzed by statistical method.ResultsA total number of 311 cases were selected.The median baselineT lymphocyte countsM(P25,P75) was 440(391,525) cells/μl.The difference ofT lymphocyte counts was significant between 6 month and baseline,12 month and 6 month,18 month and 12 month(Z=-6.6,P<0.01;Z=-3.6,P<0.01;Z=-2.5,P=0.01),and after treatment theT lymphocyte counts respectively raised by 84,123,143,140 cells/μl compared with the baseline.T lymphocyte counts had a tendency to change over time(F=31.56,P<0.01),and theT lymphocyte counts was different between different baselineT lymphocyte count groups after treatment(F=20.54,P<0.01).After treatment the increment ofT lymphocyte counts in the >500 cells/μl group was less than that of the 351-500 cells/μl group.ConclusionAfterT lymphocyte counts has an obvious increase in the first six months,then increases slowly and the increasing amplitude gradually stabilizes.The patients with a higher baselineT cell counts have a better immune function recovery.
