To evaluate the on-going scale-up of HIV programs, we assessed trends in patient characteristics at enrolment and ART initiation over 7 years of implementation.
Data were from Optimal Models, a prospective open cohort study of HIV-infected (HIV+) adults (≥15 years) and children (<15 years) enrolled from January 2005 to December 2011 at 44 HIV clinics in 3 regions of mainland Tanzania (Kagera, Kigoma, Pwani) and Zanzibar. Comparative statistics for trends in characteristics of patients enrolled in 2005-2007, 2008-2009 and 2010-2011 were examined.
Overall 62,801 HIV + patients were enrolled: 58,102(92.5%) adults, (66.5% female); 4,699(7.5%) children.Among adults, pregnant women enrolment increased: 6.8%, 2005-2007; 12.1%, 2008-2009; 17.2%, 2010-2011; as did entry into care from prevention of mother-to-child HIV transmission (PMTCT) programs: 6.6%, 2005-2007; 9.5%, 2008-2009; 12.6%, 2010-2011. WHO stage IV at enrolment declined: 27.1%, 2005-2007; 20.2%, 2008-2009; 11.1% 2010-2011. Of the 42.5% and 29.5% with CD4+ data at enrolment and ART initiation respectively, median CD4+ count increased: 210 cells/μL, 2005-2007; 262 cells/μL, 2008-2009; 266 cells/μL 2010-2011; but median CD4+ at ART initiation did not change (148 cells/μL overall). Stavudine initiation declined: 84.9%, 2005-2007; 43.1%, 2008-2009; 19.7%, 2010-2011.Among children, median age (years) at enrolment decreased from 6.1(IQR:2.7-10.0) in 2005-2007 to 4.8(IQR:1.9-8.6) in 2008-2009, and 4.1(IQR:1.5-8.1) in 2010-2011 and children <24 months increased from 18.5% to 26.1% and 31.5% respectively. Entry from PMTCT was 7.0%, 2005-2007; 10.7%, 2008-2009; 15.0%, 2010-2011. WHO stage IV at enrolment declined from 22.9%, 2005-2007, to 18.3%, 2008-2009 to 13.9%, 2010-2011. Proportion initiating stavudine was 39.8% 2005-2007; 39.5%, 2008-2009; 26.1%, 2010-2011. Median age at ART initiation also declined significantly.
Over time, the proportion of pregnant women and of adults and children enrolled from PMTCT programs increased. There was a decline in adults and children with advanced HIV disease at enrolment and initiation of stavudine. Pediatric age at enrolment and ART initiation declined. Results suggest HIV program maturation from an emergency response.
为了评估艾滋病毒规划的持续扩大,我们评估了 7 年来患者入组时的特征趋势和抗逆转录病毒治疗(ART)的开始。
数据来自 Optimal Models,这是一项针对艾滋病毒感染(HIV +)成人(≥15 岁)和儿童(<15 岁)的前瞻性开放队列研究,于 2005 年 1 月至 2011 年 12 月在坦桑尼亚大陆的 3 个地区(卡盖拉、基戈马、蓬韦)和桑给巴尔的 44 个艾滋病毒诊所招募。对 2005-2007 年、2008-2009 年和 2010-2011 年入组患者的特征进行了比较。
共有 62801 名 HIV +患者入组:58102 名(92.5%)成人,(66.5%为女性);4699 名(7.5%)儿童。在成年人中,孕妇入组增加:6.8%,2005-2007 年;12.1%,2008-2009 年;17.2%,2010-2011 年;从预防母婴传播(PMTCT)项目进入护理也增加了:6.6%,2005-2007 年;9.5%,2008-2009 年;12.6%,2010-2011 年。入组时的世界卫生组织(WHO)IV 期下降:27.1%,2005-2007 年;20.2%,2008-2009 年;11.1%,2010-2011 年。在分别有 CD4+数据的 42.5%和 29.5%的人中,中位 CD4+计数增加:210 个细胞/μL,2005-2007 年;262 个细胞/μL,2008-2009 年;266 个细胞/μL,2010-2011 年;但 ART 开始时的中位 CD4+没有变化(总体为 148 个细胞/μL)。司他夫定的起始减少:84.9%,2005-2007 年;43.1%,2008-2009 年;19.7%,2010-2011 年。在儿童中,入组时的中位年龄(岁)从 2005-2007 年的 6.1(IQR:2.7-10.0)下降到 2008-2009 年的 4.8(IQR:1.9-8.6),到 2010-2011 年的 4.1(IQR:1.5-8.1),<24 个月的儿童从 18.5%增加到 26.1%和 31.5%。从 PMTCT 进入的比例为 7.0%,2005-2007 年;10.7%,2008-2009 年;15.0%,2010-2011 年。入组时的世界卫生组织(WHO)IV 期从 2005-2007 年的 22.9%下降到 2008-2009 年的 18.3%,到 2010-2011 年的 13.9%。起始使用司他夫定的比例为 39.8%,2005-2007 年;39.5%,2008-2009 年;26.1%,2010-2011 年。ART 开始时的儿童年龄中位数也显著下降。
随着时间的推移,孕妇和成人以及从 PMTCT 项目入组的儿童的比例增加。入组时患有晚期艾滋病的成年人和儿童人数减少,开始使用司他夫定。入组和开始接受抗逆转录病毒治疗的儿科年龄下降。结果表明,艾滋病毒规划已从应急反应走向成熟。
