Combination antimicrobial therapy.

D M Shlaes, S N Bass

    Pediatric Clinics of North America
    |February 1, 1983
    PubMed
    Summary

    Clinical relevance of antimicrobial combinations is unclear. Avoid antagonistic antibiotic combinations in severe infections, and monitor therapy via bactericidal titers.

    Area of Science:

    • Infectious Diseases
    • Pharmacology
    • Clinical Microbiology

    Background:

    • Extensive in vitro data exists on antimicrobial activity.
    • Clinical relevance of in vitro antimicrobial studies remains unclear.
    • Few comparative trials evaluate combined vs. single antibiotic therapy in human infections.

    Purpose of the Study:

    • To clarify the clinical relevance of antimicrobial combination therapy.
    • To highlight specific circumstances where synergistic combinations are beneficial.
    • To advise against antagonistic combinations in critical infections.

    Main Methods:

    • Review of existing literature on antimicrobial combination therapy.
    • Analysis of clinical trial data where available.
    • Discussion of therapeutic monitoring strategies.

    Main Results:

    • Synergistic antibiotic combinations show benefit in select cases.
    • Antagonistic combinations pose risks and should be avoided in meningitis, endocarditis, and immunocompromised patients.
    • Bactericidal titers in serum or spinal fluid are crucial for monitoring therapy effectiveness.

    Conclusions:

    • Clinical application of antimicrobial combination data requires careful consideration.
    • Therapeutic drug monitoring using bactericidal titers is essential for guiding treatment of severe infections.
    • Avoiding antagonistic combinations is critical for patient outcomes.
