Impacts of HIV Treatment Regimens on Archived Drug Resistance
Impact of Antiretroviral Therapy (ART) Switch on Archived HIV-1 Drug Resistance in Virally Suppressed Patients: A Prospective Cohort Study
Studie Overzicht
Toestand
Gedetailleerde beschrijving
Aim/objectives: With the aim of determining the impact of antiretroviral regimen and switch on archived HIV-1 drug resistance mutation (DRM), the study's objectives are, to: (a) estimate the prevalence of DRM in virally suppressed HIV infection; (b) assess changes in archived resistance before and after switch; and (c) identify predictors of archived DRM after regimen switch.
Design: A prospective observational study
Setting: All HIV specialist clinic services in Hong Kong
Methods: Adults living with HIV infection on antiretroviral therapy (ART) with full viral suppression who are planned for regimen switch would be recruited. Controls are patients with and without low level viraemia (LLV) not planned for switch, matched by antiretroviral regimen. Blood samples would be collected before switch, shortly and then 2-3 years after switch. Nanopore sequencing would be performed to identify DRM present in HIV-1 proviral DNA. Transcription of relevant clinical record data would be made to contribute to statistical and phylogenetic analyses
Main outcome measures: Change in DRM frequency between baseline and followups at (a) short term and long term; (b) occurrence of virological failure and time to failure; (c) difference in DRM frequency between presence and absence of LLV, and switched and non-switched patients.
Anticipated outcome: The study results would determine if archived resistance clearance would change following ART switch, identify factors associated with persistence of archived resistance, and inform management on the application of proviral DNA testing in clinical practice.
