Filter by:Chronic pain is a worldwide health problem due to its high prevalence and its difficult management with a significant impact on quality of life. Pain and addiction co-occur frequently. Indeed, the prevalence of addiction in patients with chronic non-cancer pain may affect from 0% to 50% of patients (Højsted et al 2010). This large variability in the estimation of addiction prevalence in chronic non-cancer pain patients is at least partly due to a lack of standardization of the selected patients from the clinical or therapeutic point of view and the lack of consensus in the use of a specific evaluation tool or gold standard. Indeed, several tools are currently available at the international level with varying efficiencies and precisions (Chou et al 2009, Turk, Swanson, and Gatchel 2008, Højsted and Sjøgren 2007). In France, no data are available on the prevalence of analgesic opioid misuse in chronic non-cancer pain patients, due to the lack clinical studies and validated tools in French.
Background: The chemical messenger dopamine carries signals between brain cells. It may affect addiction. Heavy use of pain medicines called opioids may decrease the amount of dopamine available to the brain. Researchers want to study if decreased dopamine decreases self-control and increases impulsiveness. Objective: To learn more about how opiate use disorder affects dopamine in the brain. Eligibility: Adults 18-80 years old who are moderate or severe opiate users Healthy volunteers the same age Design: Participants will first be screened under another protocol. They will: - Have a physical exam - Answer questions about their medical, psychiatric, and alcohol and drug use history - Take an MRI screening questionnaire - Give blood and urine samples - Have their breath tested for alcohol Participants will have up to 3 study visits. They will have 2-3 positron emission tomography (PET) scans. A radioactive chemical will be injected for the scans. Participants will lie on a bed that slides in and out of the donut-shaped scanner. A cap or plastic mask may be placed on the head. Vital signs will be taken before and after the PET scans. Participants will get capsules of placebo or the study drug. They will rate how they feel before, during and after. Participants will have their breath and urine tested each day. Participants will have magnetic resonance imaging (MRI) scans. They will lie on a table that slides into a cylinder in a strong magnetic field. They may do tasks on a computer screen while inside the scanner. Participants will have tests of memory, attention, and thinking. Participants will wear an activity monitor for one week....
The U.S. is in the midst of an epidemic of opioid overdose deaths. The common use of opioids among persons living with HIV, along with their common use of benzodiazepines, has resulted in high rates of opioid overdose among this population. This study will test the implementation of evidence-based training, mentoring, technical support, and academic detailing to encourage HIV physicians to adopt evidence-based interventions to reduce overdose risk and treat opioid addiction.
PURPOSE: Assess the risks of long-term opioid therapy, especially opioid use disorders such as opioid-related chemical coping in chronic noncancer pain patients. Pain, particularly chronic pain, is a major threat to the quality of life worldwide and will become more so as the average age increases. Currently, over 30% of the world's population is known to have chronic pain. Among a plethora of treatment options, opioid agonists is one of treatment options for moderate to severe chronic pain. Although its consumption has increased during the last two decades,3 it remains below the requirements in most regions, including the Asian countries. In South Korea (S. Korea), opioid consumption for medical purposes in 2015 was still below average, ranked 43rd globally and 30th among 35 Organisation for Economic Co-operation and Development (OECD) countries (55 mg/capita in S. Korea vs. 258 mg/capita in an average of OECD countries). Conversely, in countries with high opioid consumption such as the United States of America (US), drug overdose deaths (the majority involving an opioid) have nearly quadrupled since 1999. The up to date literature on opioid use disorder (OUD) is characterized by great variability of definitions, measurements, demographics, and opioid use duration. Moreover, an overwhelming majority of the studies took place in the US, the country with the highest opioid consumption and a current opioid crisis. Additionally, stringent restrictions and regulations to prevent OUD may result in inadequate pain control and insufficient opioid therapy, especially in countries with relatively low-moderate opioid consumption rates. Therefore, in compliance with growth in medical opioid use and the lack of studies in countries with low-moderate opioid consumption, it is necessary to determine the occurrence of OUD in chronic noncancer pain (CNCP) patients receiving long-term opioid therapy (LtOT). In this study, we will perform a national, multicenter, observational cross-sectional study to address the current status of opioid treatment for CNCP in S. Korea, a country with moderate opioid consumption. The ultimate aims of this study are to estimate the frequency of OUD such as OrCC, to evaluate the functional and psychiatric characteristics of patients, and to determine the risk factors associated with OUD in CNCP patients receiving LtOT.
INTRO-HCV is a multicentre randomised controlled clinical trial that will compare the efficacy of integrated treatment of chronic hepatitis C virus infection (HCV) within medically assisted rehabilitation (MAR) clinics providing opioid substitution therapy (OST) compared to standard treatment. The trial will recruit approximately 250 HCV infected in Bergen and Stavanger and about 1000 in a linked observational study. Intervention: Integrating diagnostic and treatment follow-up for HCV treatment into MAR outpatient clinics in Bergen and Stavanger including testing for HCV, counselling and treatment evaluation and treatment delivery. Primary objectives: Compare the effect of integrated HCV treatment assessed with sustained virological response at 12 weeks between the MAR outpatient clinics in Bergen and Stavanger (intervention arm) with standard treatment provided after referral to infectious disease clinics among patients who receive OST having HCV Secondary objectives: Compare treatment adherence between the intervention and control arms, and assess changes in quality of life, fatigue and psychological well-being before and after HCV treatment, as well as changes in drug use, infection related risk behavior, and risk of reinfection among those with sustained virological response. Main endpoint: Sustained virological response of HCV at 12 weeks (± 10 days) Study population: The target group will be patients receiving care with MAR from involved outpatient clinics in Bergen, Sandnes and Stavanger who are chronically infected with HCV and eligible for treatment according to national guidelines. Study duration: Participants will be included and followed up at least annually for the total study duration between 2017 and 2021. Expected outcome: This study will inform on the relative advantages and disadvantages of an integrated treatment program for HCV into MAR compared to standard care aiming to increase access to treatment and improved treatment adherence. If the integrated treatment structure is found to be safe and efficacious, it can be considered for further scale-up.
In this treatment development project, the investigators propose to develop and assess the feasibility and acceptability of a narrative-based video intervention and accompanying workbook (entitled MATTeRS: Medication Assisted Treatments: Telling Real Stories) designed to be used by people in inpatient opioid detoxification. Using the Health Belief Model as a framework, videos will provide information about the uses and outcomes of Medication Assisted Treatments (MATs) compared to other or no post-detoxification treatment through the use of narratives from real people's lives.
This trial will recruit syringe exchange participants with opioid use disorder in New York City and test whether starting buprenorphine treatment at the syringe exchange program is more effective than referral to a community health center for buprenorphine treatment.
The overall goal of this project is to develop initial human data on effects of novel compounds on safety (interactions with oxycodone) and efficacy (subjective response to oxycodone) in non-treatment seeking opioid use disorder subjects. The compound to be studied will be the 5-HT2CR agonist lorcaserin. There are no known or reported adverse interactions between lorcaserin and oxycodone or other opioids.
The purpose of Project 2 is to execute phase I functional magnetic resonance imaging (fMRI) studies to assess the effects of lorcaserin on brain target engagement (measured by fMRI brain activation and neural connectivity) in cocaine use disorder (CocUD) subjects and/or opioid use disorder.
This clinical trial is being conducted to compare concentrations of hydrocodone and acetaminophen in the blood after administration of different amounts of tablets of a new and a marketed tablet formulation in healthy adults. Part 1 is a randomized, single-site, open-label, 4-treatment, 4-period crossover, single oral dose Phase I trial in 32 healthy male and female subjects. Part will consist of an Enrollment Visit, 4 treatment periods (each lasting approximately 90 hours), and a Final Examination. The treatment periods will be separated by a washout period each lasting at least 7 days. Part 2 is optional and depending on pharmacokinetic data review after Part 1. It is a randomized, single-site, open-label, 2-treatment, 2-period crossover, single oral dose part in healthy male and female subjects. Part 2 will consist of an Enrollment Visit, 2 treatment periods (each lasting approximately 90 hours) and a Final Examination. The treatment periods will be separated by a washout period lasting at least 7 days. Participants must fast for approximately 10 hours prior to administration of Investigational medicinal product (IMP) and until approximately 4 hours after the administration of the IMP.
