Antiretroviral therapy (ART) rollout in resource-limited settings risks high-level HIV resistance due to limited monitoring. This can compromise future treatment efficacy, highlighting a critical public health challenge.

Area of Science:

  • Public Health
  • Infectious Diseases
  • Virology

Background:

  • Antiretroviral therapy (ART) is crucial for managing Human Immunodeficiency Virus (HIV).
  • Resource-limited countries face unique challenges in ART implementation, often lacking routine virological monitoring.
  • Standardized first- and second-line therapies are common in these settings.

Purpose of the Study:

  • To examine the consequences of limited virological monitoring during ART in resource-limited settings.
  • To investigate the potential for high-level HIV drug resistance during first-line therapy.
  • To understand the impact of resistance on the effectiveness of second-line ART regimens.

Main Methods:

  • The study reviews existing evidence on ART resistance patterns.

  • It contrasts monitoring strategies in developed versus resource-poor countries.
  • It considers factors like HIV subtypes and drug combinations prevalent in different regions.

    • Main Results:

    • Limited monitoring in resource-limited settings increases the risk of prolonged virological failure on first-line ART.
    • This prolonged failure is likely to drive the emergence of high-level HIV drug resistance.
    • Existing data on ART resistance primarily comes from developed countries and may not apply to resource-poor contexts.

    Conclusions:

    • The emergence of high-level HIV resistance during first-line ART is a significant concern in resource-limited settings.
    • This resistance can compromise the effectiveness of subsequent treatment lines.
    • Further research is needed on ART resistance in resource-poor contexts, considering local factors.
