Point

●MRSAはメチシリン耐性黄色ブドウ球菌の略であるが,現実的には多剤耐性黄色ブドウ菌である.近年,市中関連型MRSA(CA-MRSA)が市中でも院内でも増加している.

●抗MRSA薬として,細胞壁合成阻害のバンコマイシン(VCM)とテイコプラニン(TEIC),蛋白合成阻害のアルベカシン(ABK)とリネゾリド(LZD),膜障害のダプトマイシン(DAP)の5薬剤が認可されている.

●VCM,TEIC,LZDの短時間殺菌力は弱いが,ABKとDAPは強い.菌血症などの早急な除菌が必要な症例には殺菌性を考慮すべきである.

●米国臨床検査標準協会(CLSI)で感性と判定されるVCMの最小発育阻止濃度(MIC)値が2μg/mLを示す株に対しては,VCMによる治療はPK/PD理論からも期待できない.
