The treatment of endocarditis caused by Staphylococcus (Micrococcus) pyogenes var. aureus has become a challenging problem; therefore, two patients successfully treated with a new antibiotic agent, ristocetin, are reported on here. In these two patients, the infections were acquired in hospitals and, as might be expected, the staphylococci were resistant to penicillin. Each was critically ill when therapy was started, and the use of ristocetin was associated with prompt clinical improvement and eventual bacteriological cure.
Thrombophlebitis of severe degree developed in both patients and complicated administration of the antibiotic, and severe leukopenia occurred approximately two weeks after the onset of therapy in both patients. These complications cleared after completion of therapy.
