Emerging drug-resistant strains of HIV, hepatitis B/C, and herpesviruses complicate treatment. Genotypic analysis offers a path to personalized antiviral therapies by identifying specific mutations for improved patient outcomes.

Area of Science:

  • Virology
  • Infectious Diseases
  • Medical Genetics

Background:

  • Antiviral drug resistance in HIV-1, hepatitis B (HBV), and hepatitis C (HCV) complicates treatment.
  • Emergence of drug-resistant herpesviruses (HSV, VZV, CMV) is linked to prolonged therapy in immunocompromised individuals.

Purpose of the Study:

  • To highlight the role of genotypic analysis in managing viral infections.
  • To emphasize the need for standardized genotypic testing for optimal patient treatment.

Main Methods:

  • Discusses the challenges posed by drug-resistant viral strains.
  • Explains the utility of commercial genotypic analysis systems.
  • Mentions the correlation of genotypic assays with phenotypic results and clinical outcomes.

Main Results:

  • Genotypic analysis can identify specific mutations conferring drug resistance.
  • Standardized genotypic testing can improve treatment strategies.
  • Commercial systems facilitate recognition and interpretation of mutations.

Conclusions:

  • Genotypic assays are crucial for recognizing and managing antiviral drug resistance.
  • Correlation with phenotypic data and long-term studies is essential for clinical adoption.
  • Personalized treatment based on genotypic patterns can optimize patient care.
