ABSTRACT
BACKGROUND:
Anemia may be associated with poor clinical outcomes among people living with human immunodeficiency virus (HIV) (PLHIV) despite highly active antiretroviral therapy (HAART). There are concerns that iron supplementation may be unsafe to prevent and treat anemia among PLHIV.OBJECTIVE:
The objective of the study was to evaluate the associations of anemia and iron supplementation with mortality and viral load among PLHIV in Tanzania.METHODS:
We analyzed data from a cohort of 70,442 nonpregnant adult PLHIV in Tanzania conducted between 2015 and 2019. Regression models evaluated the relationships between anemia severity and iron supplement use with mortality and unsuppressed HIV-1 viral load among all participants and stratified by whether participants were initiating or continuing HAART.RESULTS:
Anemia was associated with an increased risk of mortality and unsuppressed viral load for participants who initiated or continued HAART. Iron supplement use was associated with reduced mortality risk but also had a greater risk of an unsuppressed viral load among participants continuing HAART. There was no association of iron supplement use with mortality, and unsuppressed viral load among PLHIV that were initiating HAART. There was a stronger negative association between iron supplement use and the risk of having an unsuppressed viral load among participants with stage III/IV disease compared with stage I/II disease.CONCLUSIONS:
Anemia is associated with increased risk of mortality and unsuppressed viral load, but the benefits and safety of iron supplements appear to differ for those initiating compared with continuing ART as well as by HIV disease severity.Key words
