Complex Anemia in Tuberculosis: The Need to Consider Causes and Timing When Designing Interventions

摘要

Background. Anemia is common in tuberculosis, and multiple etiologies necessitate targeted interventions. The proportion of iron-responsive anemia due to iron deficiency compared with iron-unresponsive anemia due to impaired iron absorption/redistribution from tuberculosis-associated immune activation or inflammation is unknown. This impedes selection of safe and effective treatment and appropriate intervention timing.
