Opioid use disorder (OUD) is prevalent and causes substantial health and social burdens. Although evidence have showed the effectiveness of opioid agonist maintenance therapy in OUD, high drop-out rate and the requirement of continuing use of opioid agonists are the major problems. Therefore, to develop novel treatment for OUD is important. Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive method of brain stimulation used to treat a variety of neuropsychiatric disorders. Recent studies showed that there may be potential therapeutic effects in rTMS for addictive disorder, including reducing craving and substance use severity. The underlying mechanisms of rTMS in treating addictions may involve increased dopamine function in corticomesolimbic brain circuits and modulation of neural activity in brain circuits that relevant to addiction. However, the treatment results of rTMS in OUD were lacked, and the analysis in functional brain imaging study, neuropsychological tests and other potential biomarkers under rTMS treatment were limited, too. Thus, the investigators will conduct the add-on double-blinded, sham-controlled study rTMS treatment in 40-60 patients with OUD under methadone maintenance therapy. Patients will be allocated to active and sham rTMS in a 1 : 1 ratio, and participants will receive rTMS on the left dorsolateral prefrontal cortex (DLPFC) (15 Hz frequency, 4 seconds per train, inter-train interval of 26 seconds, 40 trains per session, total 11 sessions in 4 weeks). The treatment response, urine drug tests, craving scales and side effects to evaluate the therapeutic effects of rTMS will be examined. Neuropsychological assessments, functional magnetic resonance imaging (fMRI) and tests for potential biomarkers of immune parameters will also be measured during 12-weeks follow up. The study results will provide the important data in whether rTMS add-on methadone maintenance therapy is able to 1) reduce heroin use; 2) reduce craving for heroin; 3) be an effective treatment for OUD, and 4) be associated with improvement in fMRI, biological markers and psychological tests.
The study compared the effectiveness and cost-effectiveness of two dominant heroin dependence treatment approaches: center-based compulsory rehabilitation (CCT) and community-based voluntary methadone treatment (MMT) in Hai Phong City, Vietnam. The design was a combined retrospective and prospective, non-randomized cohort over three years (with data at five time-points). The study was conducted between 2012 and 2015, involving 208 CCT participants and 384 MMT participants with heroin dependence.
This research deals with behaviors that are part of opioid dependence. The purpose is to study how stress and medication dose can affect opioid drug use.
The study will test the efficacy of a hour long, one-on-one, active listening counseling session (called Change the Cycle or CTC) aimed at reducing behaviors among active people who inject drugs (PWID) that research has found to facilitate uptake of injection drug use among non-injectors. The study will involve ~1,100 PWID who will be randomized to CTC or an equal attention control intervention on improving nutrition. Participants will be recruited in Los Angeles and San Francisco, California and followed up at 6 and 12 months to determine changes in direct and indirect facilitation of injection initiation among non-injectors.
The purpose of this study is to evaluate tolerability, acceptability and potential efficacy of 4 months of maintenance treatment with Mirtazapine as compared to placebo for patients with co-occurring amphetamine-type stimulant and opioid dependence (COATS) receiving buprenorphine maintenance treatment (BMT) in Kota Bharu.
The proposed study will evaluate the tolerability, acceptability and potential efficacy of paliparidone for the treatment of co-occurring opioid and amphetamine-type stimulant (ATS) dependence. In the proposed clinical trial, all patients will first discontinue illicit opioid and ATS and be inducted onto buprenorphine maintenance treatment (BMT) in the inpatient ward at the department of psychiatry before beginning to receive paliparidone. Tolerability and acceptability will be evaluated by assessing the rates of patient retention during treatment, patient satisfaction with treatment and adverse effects during treatment. The potential efficacy of paliparidone will be evaluated with regard to the primary outcome measure: reductions in illicit ATS use, based on urine toxicology testing and self-report. Secondary outcome measures include treatment retention, reduction in HIV risk behaviors and improvements in functional status.
The proposed study will evaluate the tolerability, acceptability and potential efficacy of minocycline for the treatment of co-occurring opioid and amphetamine-type stimulant (ATS) dependence. In the proposed clinical trial, all patients will first discontinue illicit opioid and ATS and be inducted onto buprenorphine maintenance treatment (BMT) in the inpatient ward at the department of psychiatry before beginning to receive minocycline. Tolerability and acceptability will be evaluated by assessing the rates of patient retention during treatment, patient satisfaction with treatment and adverse effects during treatment. The potential efficacy of minocycline will be evaluated with regard to the primary outcome measure: reductions in ATS use , based on urine toxicology testing and self-report. Secondary outcome measures include retention, reduction in HIV risk behaviors and improvements in functional status.
Methadone maintenance treatment (MMT) has been one of the most effective treatment choices for opioid addicts to reduce their heroin use, criminality and spread of HIV. In Taiwan, MMT has been introduced since 2006. To date, more than 30,000 opioid addicts have ever participated in MMT, but only around 10,000 retains in treatment. Outcomes of the ever-treated MMT patients remain unclear. It is crucial to trace the opioid addicts' treatment career, outcomes and unmet treatment needs for the service providers to modify treatment strategy to help these individual to maintain abstinence. Moreover, understanding of the determinants for these subjects' long-term outcomes is important for policy makers to implement realistic policies to motivate the service providers and patients. From the results of previous research, the research team found that early dropout, defined as stayed in-treatment less than one month, of MMT participants were 14.4%. The rate of maintaining in treatment at 3rd , 6th, and 12th month were 65.7%、51.3% and 33.8%, respectively. Average treatment days for 12-month is 186.9±141.2. This result showed that the effectiveness of the MMT was varied among different facilities. On the other hand, the quality of the MMT can be improved largely through different dimensions. Besides, if one participant can enhance its motivation in staying in-treatment, it could reduce 15% early dropout. Above all, the result also showed that though the quality of life was recorded as improved after MMT, it appeared to be significantly lower than their healthy counterparties. The assessments of health outcomes after participating MMT are rare, but in need. It is necessary to make some modification to improve the effectiveness. Moreover, the evaluation of the needs shall not limit to patients, but also extend to their family members. Therefore, in this study, the research team plans to probe the dimensions from physical, psychiatric, to social conditions by assessing patients and their family members after treated by MMT for five years. The research team would like to know more about the outcomes of those who attended MMT five years ago, their physical and mental health conditions, also health status of their family members.
This study evaluates the biological markers of treatment of opioid dependent individuals with an extended release formulation of the opioid antagonist naltrexone. The biological measures include functional MRI, blood levels of naltrexone and its metabolites, urine toxicology and behavioral tests probing various aspects of personality, memory, reward processing and attention.
The purpose of the study ( observational and prospective ) is to evaluate the efficacy and tolerability of the methadone maintenance treatment in patients addicted to heroin. The efficacy and tolerability are assessed by correlating to the adequacy of the dosage of methadone. The patients will be observed for two years.
