Changes in Total Lymphocyte Count as a Surrogate in Monitoring HIV/AIDS Patients

【摘要】 目的 研究人类免疫缺陷病毒(HIV)感染者和获得性免疫缺陷综合症(AIDS)患者CD4+T淋巴细胞数变化(ΔCD4+T)和外周血淋巴细胞总数变化(ΔTLC)的相关性。探讨用ΔTLC预测ΔCD4+T在监测HIV/AIDS患者疾病进展以及高效抗逆转录病毒治疗(HAART)疗效的价值。 方法 回顾性分析2005〖CD3/5〗2008年确诊的91例HIV/AIDS患者的临床资料。 结果 ΔTLC与ΔCD4+T呈直线正相关(r=0809,Plt;001),好于TLC与CD4+T的相关性(r=0712,Plt;001)。分别用ΔTLC 170、330、630、910个/μL细胞预测ΔCD4+T 50、100、200、300个/μL细胞时具有较好的预测价值,各项评价指标符合率基本达到90%以上,显著高于相同时间下用TLC预测CD4+T计数的价值。 结论 应用ΔTLC预测ΔCD4+T,可比TLC更加直观、准确的反映HIV感染者疾病进展和评价AIDS患者HAART的疗效。【Abstract 】Objective To assess the utility of total lymphocyte count (TLC) changes (ΔTLC) in place of TLC to predict the development of HIV/AIDS. To investigate the monitoring value of ΔCD4+T on progress of HIV/AIDS and HAART which predicted by ΔTLC. Methods Clinical data of 91 patiens with HIV/AIDS diagnosed from 2005 to 2009 were retrospectively analyzed. Results A linear correlation was found between the value of ΔTLC and the value of CD4+T changes(ΔCD4+T)(r=0809,Plt;001),which was better than the correlation between TLC and CD4+T (r=0712,Plt;001).Using ΔTLC as 170,330,630,910 cells/μL,respectively for forecasting ΔCD4+T as 50,100,200,300 cells/μL,respectively,had a better predictive value with the area under ROC curve near to 09,significantly higher than using TLC for predicting CD4+T counts. Conclusion ΔTLC is more accurate than TLC to reflect the development of HIV/AIDS.
