多西環素耐藥的黴漿菌感染替代治療方案

針對多西環素耐藥的黴漿菌感染,最佳替代藥物為大環內酯類(如阿奇黴素)或氟喹諾酮類(如左氧氟沙星或莫西沙星),療程依據感染部位和嚴重程度為7-14天。

黴漿菌感染替代治療選擇

肺炎黴漿菌 (Mycoplasma pneumoniae) 感染

  • 首選替代藥物:阿奇黴素,500 mg口服第一天,然後250 mg口服每天一次,共5天 1
  • 其他替代選擇:
    • 左氧氟沙星 750 mg口服/靜脈注射,每天一次,療程7-14天 1
    • 莫西沙星 400 mg口服/靜脈注射,每天一次,療程7-14天 1

生殖道黴漿菌 (Mycoplasma genitalium) 感染

  • 對於大環內酯類敏感的感染:
    • 阿奇黴素 500 mg口服第一天,然後250 mg口服每天一次,共4天 1, 2
  • 對於大環內酯類耐藥的感染:
    • 莫西沙星 400 mg口服,每天一次,療程7天 1, 2
  • 對於高度耐藥的感染(同時對大環內酯類和氟喹諾酮類耐藥):
    • 考慮使用多西環素與莫西沙星聯合治療 3
    • 或考慮使用司他氟沙星與多西環素聯合治療 4

治療策略與考量

基於耐藥性的治療選擇

  • 在開始治療前,應盡可能進行藥物敏感性測試,特別是對於生殖道黴漿菌感染 2
  • 對於大環內酯類耐藥性已達30-90%的地區,應考慮使用氟喹諾酮類藥物 5
  • 對於parC基因突變(特別是S83I)的生殖道黴漿菌,莫西沙星的治療失敗率高達62.5% 6

特殊人群考量

  • 兒童(<8歲):避免使用四環素類(如多西環素)和氟喹諾酮類藥物,優先考慮大環內酯類 5
  • 孕婦:應避免使用多西環素和氟喹諾酮類藥物,可考慮使用大環內酯類 1

療程長度

  • 肺炎黴漿菌感染:通常需要7-14天的療程 1
  • 生殖道黴漿菌感染:
    • 阿奇黴素:5天(500 mg第一天,然後250 mg每天,共5天)2
    • 莫西沙星:7天(400 mg每天一次)2
    • 對於複雜性感染(如盆腔炎):莫西沙星治療可能需要延長至14天 2

注意事項與警告

  • 大環內酯類耐藥性與23S rRNA的點突變相關,可導致治療失敗 5
  • 氟喹諾酮類耐藥性正在增加,特別是在亞洲地區 2, 3
  • 治療失敗後,應考慮聯合治療策略,如多西環素與莫西沙星或阿奇黴素的序貫治療 3
  • 對於高度耐藥的感染,可能需要專科醫師會診和個體化治療方案 6, 4
