【摘要】目的了解新疆維吾爾自治區伊犁州HIV感染者早期高效抗反轉錄病毒治療后T淋巴細胞水平的變化情況及相關影響因素。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淋巴細胞計數>350個/μl)為研究對象,收集其基線情況及治療后各隨訪時點(6個月、12個月、18個月、24個月)的相關資料并進行統計分析。結果共收集311例HIV感染者信息,基線T淋巴細胞計數的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淋巴細胞計數比較,差異均有統計學意義(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淋巴細胞計數與基線相比分別上升了84、123、143、140個/μl;T淋巴細胞計數有隨時間變化的趨勢(F=31.56,P<0.01),不同基線T淋巴細胞分組治療后T淋巴細胞計數差異有統計學意義(F=20.54,P<0.01),>500個/μl組治療后T淋巴細胞計數增長量低于351~500個/μl組。結論早期抗病毒治療后T淋巴細胞計數在前6個月升高幅度較大,隨后升高的幅度逐漸緩慢趨于穩定;基線T淋巴細胞計數越高,免疫功能恢復越好。
【關鍵詞】早期抗病毒治療;T淋巴細胞;獲得性免疫缺陷綜合征

本研究創新點:
(1)本研究調查現場選擇在新疆維吾爾自治區伊犁州,81.4%的HIV感染者為維吾爾族,使得研究對象具有較好的區域代表性。
(2) 早期抗病毒治療已在我國部分地區開展,但相關研究仍較少,本研究旨在對早期抗病毒治療效果進行評價,為早期治療提供一定的依據。

1對象與方法

1.2方法
1.2.1治療方法納入研究的HIV感染者均按照國家統一要求的免費抗病毒治療標準進行抗病毒治療,用藥方案為2種核苷類反轉錄酶抑制劑(NRTI)和1種非核苷類反轉錄酶抑制劑(NNRTI),即2NRTI+1NNRTI。


2結果
2.1HIV感染者的基本特征共有311例符合納入與排除標準的HIV感染者納入本研究。311例HIV感染者的基本特征見表1。

【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.
