Area of Science:

  • Virology
  • Infectious Diseases
  • Clinical Medicine

Background:

  • Antiretroviral therapy (ART) is key for managing HIV infections.
  • Development of drug-resistant HIV strains is a major challenge to ART efficacy.
  • Early detection of resistant strains is vital for effective patient care and public health.

Purpose of the Study:

  • To compare genotypic and phenotypic screening methods for drug-resistant HIV strains.
  • To discuss challenges associated with HIV drug resistance testing.
  • To highlight the importance of resistance detection in clinical management and transmission control.

Main Methods:

  • Review and comparison of genotypic resistance assays.
  • Review and comparison of phenotypic resistance assays.
  • Discussion of practical aspects and limitations of HIV resistance testing.

Main Results:

  • Genotypic and phenotypic methods offer different insights into HIV drug resistance.
  • Each method has specific advantages and disadvantages for clinical application.
  • Standardized protocols and interpretation guidelines are essential for accurate resistance testing.

Conclusions:

  • Accurate and timely detection of drug-resistant HIV is critical for optimizing patient treatment outcomes.
  • Resistance testing aids in preventing the spread of drug-resistant HIV strains.
  • Further research and standardization of testing methods are needed to combat HIV drug resistance.
