Anemia of inflammation is a hallmark of tuberculosis. Factors controlling iron metabolism during anemia of inflammation and its resolution are uncertain. Whether iron supplements should be given during antituberculosis treatment to support hemoglobin (Hb) recovery is unclear. Before and during treatment of tuberculosis, we assessed iron kinetics, as well as changes in inflammation and iron metabolism indices. In a 26-week prospective study, Tanzanian adults with tuberculosis (N = 18) were studied before treatment and then every 2 weeks during treatment; oral and intravenous iron tracers were administered before treatment and after intensive phase (8/12 weeks) and complete treatment (24 weeks). No iron supplements were given. Before treatment, hepcidin and erythroferrone (ERFE) were greatly elevated, erythrocyte iron utilization was high (∼80%), and iron absorption was negligible (
