研究概览
简要总结
This is a non-randomized behavioral trial that aims to investigate whether changes in inflammatory and type I IFN expression coincide with changes in methamphetamine use and viral load over the course of 12 weeks in HIV-positive people assigned male at birth with and without methamphetamine use disorder.
详细描述
This is a within-subjects, two-arm study with 35 HIV-positive people assigned male at birth receiving contingency management for treatment of methamphetamine use disorder and 20 HIV-positive people assigned male at birth serving as a non-substance-using healthy control (N=55 total). HIV-positive participants with methamphetamine use disorder who meet the eligibility criteria will be assigned to the contingency management treatment group. HIV-positive participants who do not use substances and meet the specific criteria will be assigned to the non-substance-using control group. Participants will be observed over 8 weeks, with another follow-up 4 weeks thereafter.

Contingency Management for Methamphetamine Reduction
8 weeks of contingency management, twice weekly visits, with escalating rewards from $10 to $40 for negative urine tests

Non-substance-using Control
Observational visits (no intervention) at baseline, Week 4, Week 8, and Week 12 for those who do not use methamphetamine.
结局指标
主要结局
Change in Inflammatory and Type I IFN Gene Expression over 12 weeks
时间窗: every 4 weeks, at baseline, Week 4, Week 8, and Week 12
Change in gene expression values -- based on count per million or reference gene normalized mRNA extracted from leukocytes and mapped to 53 a priori specified genes -- averaged over 4 times points using mixed linear regression
Change in Methamphetamine Use over 12 weeks
时间窗: twice weekly for 8 weeks with 4-week follow-up in the contingency management group; once every 4 weeks over 12 weeks for the control group.
Change in odds of methamphetamine use -- based on qualitative urine test result -- over 12 weeks.
次要结局
- Change in HIV Viral Suppression over 12 weeks(Once every 4 weeks over 12 weeks (i.e., baseline, Week 4, Week 8, Week 12))
