Rising fungal infections and drug resistance necessitate new antifungal strategies. This chapter details in vitro methods like checkerboard, E-test, and time-kill curves to evaluate antifungal drug combinations for improved treatment efficacy.

Area of Science:

  • Mycology
  • Infectious Diseases
  • Pharmacology

Background:

  • Increasing incidence of fungal infections, particularly in immunocompromised individuals.
  • Emergence of antifungal drug resistance poses a significant clinical challenge.
  • Limited therapeutic options for treating resistant fungal infections.

Purpose of the Study:

  • To explore antifungal drug combinations as a strategy to combat rising fungal infections and resistance.
  • To provide a detailed overview of in vitro methodologies for assessing antifungal combinations.
  • To guide researchers and clinicians in selecting and interpreting antifungal combination studies.

Main Methods:

  • Description of the checkerboard assay for determining drug synergy or antagonism.
  • Explanation of the E-test (gradient diffusion method) for minimum inhibitory concentration determination.

  • Detailed account of time-kill curve analysis to assess the rate and extent of fungal killing by drug combinations.

    • Main Results:

    • In vitro testing is crucial for initial evaluation of potential antifungal combinations.
    • Each described method (checkerboard, E-test, time-kill curves) offers unique insights into drug interactions.
    • Proper interpretation of results is essential for translating in vitro findings to clinical applications.

    Conclusions:

    • Antifungal drug combinations represent a promising approach to address treatment challenges.
    • Standardized in vitro methodologies are vital for the rational development of combination therapies.
    • Further research utilizing these methods can help expand the armamentarium against fungal infections.
