Clinical Report: Immune Recovery After Transitioning from EFV to BIC/FTC/TAF

Overview

Expand on the implications of the findings in relation to current treatment guidelines.

Background

Incorporate specific data or references regarding the prevalence of INRs in China.

Data Highlights

Adjust the table for clarity and include statistical significance where applicable.

Key Findings

  • The prevalence of INRs among PLWH on long-term ART in Chongqing, China, was found to be 29.9%.
  • Switching from EFV to BIC/FTC/TAF resulted in significantly greater increases in CD4 cell counts at weeks 48, 96, and 144.
  • Immune reconstitution rates were higher in the BIC/FTC/TAF group compared to the EFV group at both week 48 and week 144.
  • The immunological benefits of switching were primarily observed in patients aged ≤50 years.
  • Virological suppression rates remained high in both treatment groups throughout the study.

Clinical Implications

The findings suggest that switching from EFV-based regimens to BIC/FTC/TAF may enhance immune recovery in INRs, particularly in younger patients. Clinicians should consider this switch for eligible patients to potentially improve their immunological status while maintaining virological suppression.

Conclusion

The study highlights the potential benefits of switching ART regimens for immunological non-responders, emphasizing the need for further prospective studies to confirm these exploratory findings.
