Hemolytic anemia in a patient with subacute bacterial endocarditis due to Streptococcus sanguis
1Division of Clinical Hematology/Immunology, Kumamoto City Hospital, Japan.
We describe a case of hemolytic anemia with subacute bacterial endocarditis due to Streptococcus sanguis. The major hematological features of the patient were a normocytic anemia with reticulocytosis, an elevation of serum lactate dehydrogenase, and a marked reduction of serum haptoglobin. All these signs of hemolytic anemia fluctuated in parallel with changes in inflammatory activity and were dramatically improved by the administration of benzylpenicillin, suggesting that the infection with S. sanguis itself was the cause of hemolytic anemia in this case.
