Older persons living with HIV (PLWH), often defined as age 50 years and older, are a rapidly growing population, with high rates of chronic pain, substance use, and decreased physical functioning. No interventions currently exist that address all three of these health outcomes simultaneously. An 8-week behavioral intervention combining cognitive-behavioral therapy and tai chi reinforced with text messaging (CBT/TC/TXT) was developed and pilot tested in a community-based AIDS service organization with substance using PLWH aged 50 years and older who experienced chronic pain. Fifty-five participants were enrolled in a three arm randomized controlled trial that compared the CBT/TC/TXT intervention (N = 18) to routine Support Group (SG) (N = 19) and Assessment Only (AO) (N = 18) to assess the intervention's feasibility, acceptability and preliminary efficacy to reduce pain and substance use and improve physical performance. Participants were assessed at baseline, treatment-end (week 8) and week 12. Feasibility and acceptability indicators showed moderate levels of participant enrollment (62% of those eligible), excellent 12-week assessment completion (84%) and high attendance at CBT and tai chi sessions (>60% attended at least 6 of 8 sessions). Efficacy indicators showed within-group improvements from baseline to week 12 in the CBT/TC/TXT group, including all four substance use outcomes, percent pain relief in the past 24 h, and in two physical performance measures. Observed between-group changes included greater reductions in days of heavy drinking in the past 30 days for both CBT/TC/TXT (19%) and SG (13%) compared to the AO group. Percent pain relief in the past 24 h improved in the CBT/TC/TXT group relative to SG, and the CBT/TC/TXT's physical performance score improved relative to both the SG and AO groups. Findings demonstrate that the CBT/TC/TXT intervention is feasible to implement, acceptable and has preliminary efficacy for reducing substance use and pain and improving physical performance among a vulnerable population of older PLWH.

Background and aims

No effective pharmacotherapy for methamphetamine (MA) use disorder has yet been found. This study evaluated sustained-release methylphenidate (MPH-SR) compared with placebo (PLA) for treatment of MA use disorder in people also undergoing behavioral support and motivational incentives.

Design

This was a randomized, double-blind, placebo-controlled design with MPH-SR or PLA provided for 10 weeks (active phase) followed by 4 weeks of single-blind PLA. Twice-weekly clinic visits, weekly group counseling (CBT) and motivational incentives (MI) for MA-negative urine drug screens (UDS) were included.

Setting

Treatment sites were in Los Angeles, California (LA) and Honolulu, Hawaii (HH), USA.

Participants

A total of 110 MA-dependent (via DSM-IV) participants (LA = 90; HH = 20).

Measurements

The primary outcome measure is self-reported days of MA use during the last 30 days of the active phase. Included in the current analyses are drug use (UDS and self-report), retention, craving, compliance (dosing, CBT, MI), adverse events and treatment satisfaction.

Findings

No difference was found between treatment groups in self-reported days of MA use during the last 30 days of the active phase (P = 0.22). In planned secondary outcomes analyses, however, the MPH group had fewer self-reported MA use days from baseline through the active phase compared with the PLA group (P = 0.05). The MPH group also had lower craving scores and fewer marijuana-positive UDS than the PLA group in the last 30 days of the active phase. The two groups had similar retention, other drug use, adverse events and treatment satisfaction.

Conclusions

Methylphenidate may lead to a reduction in concurrent methamphetamine use when provided as treatment for patients undergoing behavioral support for moderate to severe methamphetamine use disorder, but this requires confirmation.
