Ibudilast attenuates the association between pain intensity and heavy drinking in alcohol use disorder: A secondary analysis of a randomized clinical trial
Background
Pain frequently co-occurs with alcohol use disorder (AUD) and may influence treatment response. In this secondary analysis of a completed randomized clinical trial, we examined whether baseline pain intensity and pain-related disability moderate the effects of ibudilast, a neuroimmune-modulating agent, on drinking outcomes over 12 weeks.
Method
Participants (N = 102; 60 % male; M age = 44.26, SD = 10.81) with moderate-to-severe AUD were randomized to ibudilast (50 mg twice daily) or placebo for 12 weeks. Pain intensity and disability were assessed at baseline using the Graded Chronic Pain Scale. Piecewise linear mixed-effects models tested the moderating effect of pain on percent heavy drinking days (PHDD), percent days abstinent, drinks per day, and drinks per drinking day, adjusting for early (baseline–Week 2) and late (Weeks 4–12) trial phases.
Results
Pain variables were not significantly correlated with any drinking outcome at baseline (all |r| ≤ .08, p > .45). Significant three-way interactions (Medication × Pain Intensity × Time) emerged for PHDD in both early and late phases (ps < 0.05), indicating that higher pain intensity predicted greater PHDD in the placebo arm (b = 0.10, p = .04) but not in the ibudilast arm (b = 0.007, p ≥ .89). Similar interactions were observed for pain intensity and pain-related disability on drinks per day, though simple slopes were nonsignificant. No significant moderation effects were found for percent days abstinent or drinks per drinking day.
Conclusions
Ibudilast attenuated the positive association between baseline pain intensity and heavy drinking, suggesting that pain intensity may identify an AUD subgroup more likely to benefit from neuroimmune-targeted pharmacotherapy. These findings support incorporating pain phenotyping into AUD treatment research and point toward a precision medicine approach to enhance treatment efficacy.
期刊介绍:
Alcohol is an international, peer-reviewed journal that is devoted to publishing multi-disciplinary biomedical research on all aspects of the actions or effects of alcohol on the nervous system or on other organ systems. Emphasis is given to studies into the causes and consequences of alcohol abuse and alcoholism, and biomedical aspects of diagnosis, etiology, treatment or prevention of alcohol-related health effects.
Intended for both research scientists and practicing clinicians, the journal publishes original research on the neurobiological, neurobehavioral, and pathophysiological processes associated with alcohol drinking, alcohol abuse, alcohol-seeking behavior, tolerance, dependence, withdrawal, protracted abstinence, and relapse. In addition, the journal reports studies on the effects alcohol on brain mechanisms of neuroplasticity over the life span, biological factors associated with adolescent alcohol abuse, pharmacotherapeutic strategies in the treatment of alcoholism, biological and biochemical markers of alcohol abuse and alcoholism, pathological effects of uncontrolled drinking, biomedical and molecular factors in the effects on liver, immune system, and other organ systems, and biomedical aspects of fetal alcohol spectrum disorder including mechanisms of damage, diagnosis and early detection, treatment, and prevention. Articles are published from all levels of biomedical inquiry, including the following: molecular and cellular studies of alcohol''s actions in vitro and in vivo; animal model studies of genetic, pharmacological, behavioral, developmental or pathophysiological aspects of alcohol; human studies of genetic, behavioral, cognitive, neuroimaging, or pathological aspects of alcohol drinking; clinical studies of diagnosis (including dual diagnosis), treatment, prevention, and epidemiology. The journal will publish 9 issues per year; the accepted abbreviation for Alcohol for bibliographic citation is Alcohol.
