Hemoglobin (Hb) has multiple pathophysiologic effects when released into the
intravascular space during hemolysis. The extracellular effects of Hb have
resulted in novel models of toxicity, which help to explain endothelial
dysfunction and cardiovascular complications that accompany genetic hemolytic
anemias, malaria, blood transfusion, and atherosclerosis. The majority of models
focus on nitric oxide (NO) depletion; however, in local tissue environments, Hb
can also act as a pro-oxidant and inflammatory agent. This can alter cellular
differentiation with the potential to deviate immune responses. The understanding
of these mechanisms set in the context of natural scavenger and detoxification
systems may accelerate the development of novel treatment strategies.
