[Two cases of gram-positive sepsis successfully treated with vancomycin in combination with imipenem or cilastatin].

: Against gram-positive sepsis, vancomycin (VCM) was administered in combination with imipenem or cilastatin (IPM/CS). Its excellent efficacy was confirmed in 2 cases, one affected with methicillin resistant Staphylococcus aureus and another with Gemella morbillorum. By calculating the FIC index according to a checkerboard technique, the in vitro synergistic effect was also demonstrated. At the present state multi-drug resistant gram-positive infections prevailed, the combination of VCM with IPM/CS can be expected as an effective measure for treating these diseases.
