ARV Concentrations in Hair
- Conditions
- HIV
- Interventions
- Other: Hair analysis
- Registration Number
- NCT02768779
- Lead Sponsor
- University of North Carolina, Chapel Hill
- Brief Summary
Hair samples from subjects on antiretroviral therapy, both HIV- and HIV+ patients with HIV RNA \<50copies/mL for \>6 months will be analyzed to investigate the influence of race, hair color and hair treatment on ARV response.
- Detailed Description
A small thatch of hair (approximately 20 strands) will be collected from 85 participants who are currently taking antiretrovirals (ARVs). Hair collection will be evenly distributed into color cohorts: Black, Brown, Blonde and Grey. Participants will need to be \>80% adherent to their medication and have had an undetectable HIV RNA VL within the previous 6 months. In the lab, samples will be used to develop IR-MALDESI MSI hair protocols for high sensitivity and accuracy to quantify ARVs in 5 therapeutic drug classes (Integrase Inhibitors, Nucleoside Reverse Transcriptase Inhibitors, Non-Nucleoside Reverse Transcriptase Inhibitors, Entry Inhibitors, Protease Inhibitors).
