About
This study is a 3-arm pilot, randomized, double-blinded, placebo-controlled study of low-dose naltrexone and gabapentin versus placebo among HIV-positive persons with heavy alcohol use and chronic pain to provide estimates of their effects on 1) pain; 2) inflammation; and 3) measures of HIV control. Participants will be followed for 12 weeks. Assessments of study outcomes will be compared at week 8 (end of treatment phase).
Full description
Pain is a common co-morbidity for HIV-positive patients.Prevalence studies suggest that, on average, half of all HIV-positive persons suffer pain. Chronic pain can lead to heavy alcohol use among HIV-positive persons, which may in turn be a barrier to treatment/control of HIV and contribute to spread of HIV. Thus there is an urgent need to address pain among persons with HIV. It is timely and relevant to conduct research on gabapentin, as it has emerged as one of the most commonly prescribed non-opioid medications for pain despite the fact that gabapentin is only FDA approved for "post-herpetic neuralgia" and the literature to support its use for generalized chronic pain is limited. And yet, gabapentin has demonstrated benefits for treatment of alcohol use disorder, and therefore, like naltrexone, it could have a specific role for treating patients with chronic pain and unhealthy alcohol use. This study is a 3-arm pilot, randomized, double-blinded, placebo-controlled study of low-dose naltrexone and gabapentin vs. placebo among HIV-positive persons with heavy alcohol use and chronic pain to provide estimates of their effects on 1) pain (both self-reported and experimental/cold pressor test; 2) inflammation (i.e., levels of inflammatory cytokines IL-6, IL-1β, IL-10, and TNF-α); and 3) measures of HIV control (CD4 count and viral load).
