title: Reticulocytopenic, coombs' positive anemia induced by procainamide.
abstract: A case of Coombs' positive anemia in a man who had procainamide-induced lupus erythematosus syndrome is reported. The patient had a hemoglobin of 4.3 gm/dl and reticulocytopenia (3.1% corrected). Serum lactate dehydrogenase and haptoglobin levels were normal, and total bilirubin was only slightly elevated. Two other reported cases of procainamide-induced hemolytic anemia have demonstrated similar findings. Apparently, procainamide occasionally may induce a reversible, reticulocytopenic, Coombs' positive anemia that is not associated with laboratory evidence of acute hemolysis.
