Low-dose iron supplementation does not increase HIV-1 load

Abstract

Observational data suggest that iron may increase HIV replication and the rate of progression of HIV infection. This is worrying, and may impede the international commitment to combat iron deficiency. However, it is crucial to clarify the role of iron in HIV infections, since iron is universally administered to anaemic patients and pregnant women, even in areas with high HIV prevalence. Based on a historical iron trial, we assessed the effect of 60 mg of elemental iron given twice weekly over four month on HIV-1 viral load. There was no effect on viral load, but effects of higher doses of iron cannot be excluded.
