Journal of acquired immune deficiency syndromes (1999)·2018

Drug-resistant HIV is a growing problem, with new mutations and cross-resistance patterns emerging. This necessitates advanced testing and better treatments for HIV patients facing treatment failure.

Area of Science:

  • Virology
  • Infectious Diseases
  • Antimicrobial Resistance

Background:

  • Treatment failure in HIV infection is increasingly linked to the emergence of drug-resistant viral strains.
  • New mutations, cross-resistance, and multidrug resistance patterns are complicating antiretroviral therapy.
  • Primary drug resistance, acquired through infection with resistant strains, is becoming more prevalent.

Purpose of the Study:

  • To highlight the escalating challenge of drug-resistant human immunodeficiency virus (HIV).
  • To underscore the complexities of emerging resistance patterns, including cross-resistance.
  • To emphasize the need for enhanced diagnostic tools and therapeutic strategies.

Main Methods:

  • Review of current scientific literature on HIV drug resistance.

  • Analysis of resistance mutation data and cross-resistance patterns.
  • Assessment of the clinical impact of drug-resistant HIV variants.

    • Main Results:

    • Emergence of novel HIV mutations associated with resistance to antiretroviral drugs.
    • Identification of increasing cross-resistance and multidrug resistance among HIV strains.
    • Data indicate greater cross-resistance within nucleoside reverse transcriptase inhibitors than previously understood.
    • Prevalence of primary resistance due to infection with drug-resistant HIV strains is rising.

    Conclusions:

    • The evolving spectrum of HIV-1 resistance demands more sophisticated resistance testing.
    • Enhanced clinical expertise is crucial for managing patients with drug-resistant HIV.
    • Development of more effective antiretroviral drugs is essential to combat treatment failure.
