Severe immune hemolytic anemia in disseminated tuberculosis with response to antituberculosis therapy

Severe hemolytic anemia in patients with disseminated tuberculosis is exceedingly rare. We report an episode of Coombs’-positive hemolytic anemia in a previously healthy young man with miliary tuberculosis, resulting in a hemoglobin level of 5 g/dL and an undetectable haptoglobin level. The patient responded well to treatment with antituberculosis drugs, and the results of the direct Coombs’ test became negative without the need of blood transfusion or steroid therapy. ? 2001 American College of Chest Physicians.
