Brief Summary

This three-armed, parallel-group, single-blind, multi-center randomized control trial (RCT) aims to evaluate the efficacy of probiotic supplement compared with that of acceptance and commitment therapy (ACT) in ameliorating alcohol craving and severity of alcohol use disorder (AUD) in patients diagnosed with AUD after 2 weeks of in-patient detoxification. In addition, this study also compares the efficacy of probiotic supplement and ACT to mitigate common comorbid of AUD (such as depression and anxiety symptoms); changes in event-related potential (ERP) on electroencephalogram (EEG) monitoring which indicate reduce alcohol craving; and depreciate the serum level of pro-inflammatory cytokines, such as interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) indicating lowering of systemic inflammation. In phase I of the study, 120 patients diagnosed with AUD (using Diagnostic and Statistical Manual for Mental Disorders 5th Edition or DSM-5) and 120 healthy controls will be recruited. The measured outcomes to be compared between patients with AUD and healthy non-AUD controls include ERP on EEG monitoring, serum levels of pro-inflammatory cytokines (IL-1β, IL-6, and TNF-α), and the fecal microbiota content. Then, in phase II of the study, 120 AUD patients will be randomized into three groups of intervention in a 1:1:1 ratio (Lactobacillus sp. probiotic, ACT and placebo group; n = 40 per group). The participants in probiotic and placebo groups will then consumed the Lactobacillus sp. Probiotic and placebo 1 sachet once a day of probiotic and placebo, respectively for 12 weeks. While participants in ACT group will undergo training for ACT one session per week for 8 weeks. Outcome assessments will be performed across four time points, such as t0 = before intervention began, t1 = 8 weeks after intervention began, t2 = 12 weeks after intervention began, and t3 = 24 weeks after intervention began. The primary outcomes to be measured are the degree of alcohol craving, alcohol withdrawal, and severity of alcohol use disorder. While the secondary outcomes to be assessed are severity of comorbid depression and anxiety symptoms, serum levels of pro-inflammatory cytokines (IL-1β, IL-6, and TNF-α), changes in ERP on EEG monitoring, and fecal microbiota content.

Outcome Measures

Primary Outcomes (3)

  • Change in Alcohol Use Disorder Identification Test score across four time points

    This questionnaire can screen drinkers from mild to severe.The reliability and validity of the Chinese version are 0.782. Factor analysis showed that indeed the Chinese version of the AUDIT comprised of three factors and had good convergent and discriminant validity. The scale consists of 10 questions, of which three relate to the amount and frequency of alcohol consumption, three relate to alcohol dependence and four involve in various problems caused by alcohol. The total score range from 0 to 40. The score of the scale ≥ 8 is positive. In general, those with high scores on the first three questions but low scores on the rest suggest serious harmful drinking; High scores in questions 4, 5 and 6 indicate alcohol dependence; High scores in the final section indicate that drinking has caused harm.

    At four time points of assessment: t0 (baseline) = before starting intervention, t1 = 8 weeks after intervention began, t2 = 12 weeks after intervention began, and t3 = 24 weeks after intervention began

  • Change in Clinical Institute Withdrawal Assessment for Alcohol-Revised score across four time points

    The scale is a standard tool for quantifying the severity of alcohol withdrawal symptoms. The reliability of the Chinese version of CIWA-Ar was good with Cronbach's α of 0.83. The total score range from 0 to 30. The total score \< 10 suggests mild withdrawal reaction. The score of 10 to 20 indicates moderate. And the total score of more than 20 is considered severe. A severe total score is associated with a risk of delirium tremens and seizures.

    At four time points of assessment: t0 (baseline) = before starting intervention, t1 = 8 weeks after intervention began, t2 = 12 weeks after intervention began, and t3 = 24 weeks after intervention began

  • Change in Penn Alcohol Craving Scale score across four time points

    This questionnaire consists of five items to evaluate the severity of craving, including frequency, intensity, duration, difficulty of coping, and average craving degree. The reliability of the Chinese version of PACS was good at Cronbach's α of 0.97. Each item is scored in a seven-point Likert scale from 0 to 6, with 0 being none and 6 being extremely severe. Thus, the total score range from 0 to 30. The higher the total score, the greater is the degree of craving. The subjects will be asked to answer questions according to the situation in the past week.

    At four time points of assessment: t0 (baseline) = before starting intervention, t1 = 8 weeks after intervention began, t2 = 12 weeks after intervention began, and t3 = 24 weeks after intervention began

Secondary Outcomes (7)

  • Change in Hamilton Depression Rating Scale score across four time points

    At four time points of assessment: t0 (baseline) = before starting intervention, t1 = 8 weeks after intervention began, t2 = 12 weeks after intervention began, and t3 = 24 weeks after intervention began

  • Change in Hamilton Anxiety Rating Scale score across four time points

    At four time points of assessment: t0 (baseline) = before starting intervention, t1 = 8 weeks after intervention began, t2 = 12 weeks after intervention began, and t3 = 24 weeks after intervention began

  • Change in event-related potential in EEG monitoring across four time points

    At four time points of assessment: t0 (baseline) = before starting intervention, t1 = 8 weeks after intervention began, t2 = 12 weeks after intervention began, and t3 = 24 weeks after intervention began

  • Change in serum tumor necrosis factor-α (in ng/mL) across four time points

    At four time points of assessment: t0 (baseline) = before starting intervention, t1 = 8 weeks after intervention began, t2 = 12 weeks after intervention began, and t3 = 24 weeks after intervention began

  • Change in fecal microbiota analysis across three time points

    At three time points of assessment: t0 (baseline) = before starting intervention, t1 = 8 weeks after intervention began, and t2 = 12 weeks after intervention began

  • +2 more secondary outcomes

Dietary Supplement: Placebo

Interventions

Lactobacillus sp. probioticDIETARY_SUPPLEMENT

The probiotic product contains good bacteria Lactobacillus sp. and primarily maltodextrin as carrier. Sachets of products containing the probiotic appear as light-yellow powder. The probiotic products are kept at storage temperature range below 30oC according to the condition recommended by the manufacturer.

Probiotic group

The ACT session is initiated by building good therapeutic rapport with the subject and gather important information such as experiential avoidance, external barriers, fusion past, unworkable actions, and strength of the subject, followed by formulation of the case. The session may began with coaching subjects on acknowledging and accepting their unpleasant thoughts and feelings. The therapy will also focus on defusion to reduce behavioral avoidance of unpleasant thoughts and feelings by acknowledging them but focus on the values identified. Mindfulness is also practice to allow focus onto the present and surrounding to create awareness among the subjects that they are many things in the surrounding which is more enjoyable that we can enjoy rather than making effort to distract or change or avoid the unpleasant thoughts and feelings.

Acceptance and commitment therapy (ACT) group
PlaceboDIETARY_SUPPLEMENT

The placebo are in powder form prepare in sachet which is light-yellow in color and should be stored in temperature at below 30oC, which is similar to the appearance of the probiotic. Nevertheless, it contains only maltodextrin in same amount as in the placebo.
