To examine the association of anemia with mortality and disease progression among a cohort of women with HIV in Dar es Salaam, Tanzania.
Time to all-cause death, AIDS-related death, and a 50% decrease in CD4 cell count among 1078 HIV-positive pregnant women enrolled in a clinical trial of vitamin supplementation from 1995-2003.
Adjusted models showed that anemia was associated with an increased risk of all-cause mortality (relative hazard [RH]: 2.06, 95% CI: 1.52 to 2.79 for moderate anemia and RH: 3.19, 95% CI: 2.23 to 4.56 for severe anemia) and AIDS-related mortality (RH: 2.21, 95% CI: 1.53 to 3.19 for moderate anemia and RH: 3.47, 95% CI: 2.25 to 5.33 for severe anemia), independent of CD4 cell count, World Health Organization clinical stage, age, pregnancy, vitamin supplementation, and body mass index. Anemia was also associated with a more rapid decline in CD4 counts, measured as time to a 50% drop in CD4 cell count from baseline. Erythrocyte characteristics suggestive of iron deficiency were also associated with all-cause and AIDS-related death and a 50% decline in CD4 cell count.
Anemia is an independent predictor of mortality and disease progression in this cohort. Screening for anemia, coupled with prevention and treatment efforts, should be included in HIV care initiatives, particularly those that target women.
在坦桑尼亚达累斯萨拉姆的一组感染艾滋病毒的女性队列中,研究贫血与死亡率及疾病进展之间的关联。
对1995年至2003年参加维生素补充剂临床试验的1078名艾滋病毒阳性孕妇,记录其全因死亡、艾滋病相关死亡时间以及CD4细胞计数下降50%的时间。
校正模型显示,贫血与全因死亡率增加相关(中度贫血的相对风险[RH]:2.06,95%置信区间[CI]:1.52至2.79;重度贫血的RH:3.19,95%CI:2.23至4.56)以及艾滋病相关死亡率增加相关(中度贫血的RH:2.21,95%CI:1.53至3.19;重度贫血的RH:3.47,95%CI:2.25至5.33),独立于CD4细胞计数、世界卫生组织临床分期、年龄、妊娠、维生素补充剂和体重指数。贫血还与CD4计数下降更快相关,以从基线CD4细胞计数下降50%的时间来衡量。提示缺铁的红细胞特征也与全因和艾滋病相关死亡以及CD4细胞计数下降50%相关。
在该队列中,贫血是死亡率和疾病进展的独立预测因素。艾滋病毒护理计划,尤其是针对女性的计划,应包括贫血筛查以及预防和治疗措施。
