Filter by:The current available pharmacological treatment formulations (i.e., daily formulations of buprenorphine or methadone) for OUD in France may have several inconveniences, such as: compliance, burden of daily intake, and risk of misuse; that may hinder their effectiveness. Long acting formulations of buprenorphine (LAB) such as Buvidal have been developed to favor retention and compliance and minimize the risk of diversion. Previous studies are promising on the advantage of LAB to treat opioid addiction, however more evidence is needed in the French healthcare context. However, in addition to randomized clinical trials, the French National Healthcare Agency (HAS "Haute Autorité de Santé") recommends conducting "real-life" studies (i.e., in naturalistic conditions) during the development of a medication and the use of "Patient Reported Outcome Measures" (PROMs) to analyze patient quality of life and/or other measures relevant to patients (e.g., severity, efficiency), without interpretation of the answers by a health professional. In this regard, our study proposes to use the Addiction Severity Index (ASI) self-report questions and several scales on treatment satisfaction and quality of life to collect the patient's opinion of perceived changes following the use of Buvidal. Main objectives: The objectives of this prospective open observational study, in naturalistic conditions, are to examine in individuals with an opioid use disorder, over a period of 6 months after LAB treatment initiation: the change in substance addiction severity and the changes in health-related quality of life, craving, opioids and other substance and non-substance uses and misuses, alcohol, tobacco and non-substance addiction severity, satisfaction with LAB treatment, severity of others domains related to addiction severity (i.e., medical, social, psychological) and psychiatric comorbidities Main hypotheses: 1. Hypothesize was that LAB will be associated with a stable (if prior remission) or a reduction of the CS of "Drug use" (i.e., substance addiction severity) at 6 months compared to baseline. 2. Hypothesize was that LAB will be associated with a stable (if prior remission) or a reduction of opioids and other substance and non-substance uses and misuses, other substances and non-substances addiction severity, craving, severity of others domains related to addiction (i.e., medical status, employment and support, family/social status, psychological status), an improvement of quality of life and a good satisfaction with treatment at follow-ups compared to baseline.
Objective: Analgesic Opioids misuse among patients with chronic pain ranges from 0% to 50%. The general practitioner is the first prescriber of opioid analgesics Our objective was to validate in primary care the POMI (Prescription Opioid Misuse Index) to identify the misuse of AOs. Study Setting: Patients with chronic pain, taking AOs for at least 3 months, and followed in general practice. Study design: Psychometric study Data Collection/Extraction methods: Eligible patients followed in general practice responded to the POMI: Test phase. They then responded after 2 weeks: the retest. The gold standard used was the DSM-V.
The principle is to propose dedicated monthly screening days bringing together the health personnel involved (hepatologist, addictologist, nurse in charge of the program, addictology nurse and social worker) and to propose appropriate management for each situation assessed.
the study aim is to compare betwenn the effect of mindfulness based relapse prevention and other evidence based psychotherapy interventions regaring substance craving.
Opiate addiction is a major health challenge. The mainstay of treatment is opiate substitution therapy (OST), typically methadone, but many desire to be opiate-free. Abstinence in older opiate addicts with increasingly complex health needs may also be advantageous. Detoxification generally involves tapering of OST with adjunct medication to treat emerging symptoms, but these are often ineffective or inappropriate for longer-term prescribing. New treatments are therefore needed. The investigators propose that baclofen has the desired properties to facilitate OST detoxification. It is licensed for spasticity, is currently used to treat alcoholism and there is promising pre-clinical and clinical evidence of potential efficacy in opiate dependence. Common symptoms of withdrawal are likely to be improved by baclofen. Whilst the investigators clinical experience and other studies suggest baclofen can be taken safely with methadone, they could potentially interact causing adverse effects such as respiratory depression. Also, the possibility of abuse liability remains unexplored and is an important consideration in this indication. The investigators will therefore determine the safe dose combinations of baclofen and methadone and to assess if baclofen is 'liked'. Patients engaged in treatment for opiate dependence from community addiction services and receiving stable doses of OST with methadone will be invited to undergo screening at the Imperial Clinical Research Facility (ICRF) at Hammersmith hospital, or at their local addiction clinic. Up to 64 eligible patients will attend the ICRF for an experimental visit. Acute baclofen or placebo will be orally administered (randomised, single-blind, 3:1 ratio respectively) with the dose determined by a Bayesian adaptive trial algorithm. Measures will comprise respiratory, sedation, self-report and cardiovascular monitoring, and blood sampling for 5 hours post-dose. The study duration will be ~2-3 weeks from pre-screening phone call to the post visit follow up phone call.
This is a randomized controlled trial. Patients will be randomly assigned to either the control or treatment group, with equal allocation using block randomization. The primary null hypothesis is that a combination sufentanil and buprenorphine based pain control regimen will not result in lower morphine equivalent requirements for pain control when compared to a classic fentanyl and hydromorphone based regimen. The secondary working hypothesis is that the patient satisfaction survey mean satisfaction scores will be higher in the buprenorphine and sufentanil treated group when compared to the classic fentanyl and hydropmorphone treated group. The secondary null hypothesis is that the patient satisfaction surveys mean scores will not be significantly different in the buprenorphine and sufentanil treated group when compared to the classic fentanyl and hydropmorphone treated group. The tertiary working hypothesis is that the patients will have significantly lower rates of relapse as defined by follow up with their home suboxone clinic at 2 and 4 weeks. The tertiary null hypothesis is that patients have equivalent rates of relapse as defined by follow up with their home suboxone clinic at 2 and 4 weeks.
Methadone maintenance treatment (MMT) is one of the main forms of treatments for opioid dependence. Despite its effectiveness and widespread use, people will experience withdrawal if daily dose is insufficient or missed, promoting reluctance to attempt detoxification. In addition, methadone is a full opioid agonist which can induce respiratory depression or sedation without ceiling level, so overdose usage can be fatal. Hence, an alternative therapy is needed to completely reduce the carving for drugs and to relieve the negative affective sate caused by withdrawal. Deep brain stimulation (DBS) is a reasonable treatment approach for addiction. Since 2009 the first case report emerged, the nucleus accumbens (NAc) is still the only brain target to be investigated in clinical case series of DBS for alcohol and heroin addiction. This research will mainly investigate the effectiveness and safety of NAc-DBS for patients with methadone maintenance treatment. The investigators will also explore the influence of NAc-DBS on brain activity and cognition.
