FMRI of Stress and Addictive Disorders
Cocaine DependenceOpioid Dependence3 moreThe purpose of this study is to explore whether frontal brain activation in response to stress varies as a function of the presence or extent of early trauma and whether or not this effect is greater in women compared to men. To examine the effect of stress on thinking and remembering. To examine the separate and interactive effects of stress, addiction, withdrawal, and genetics; and to examine fMRI brain activation associated with stressful, reward-related-cue and neutral/relaxing audiotaped scripts,visual images and emotional video clips in addicted individuals and in healthy controls.
Studies of Opioid Seeking Behavior: Yohimbine and Hydrocortisone Effects
Heroin DependenceOpioid-Related DisordersThis research deals with behaviors that are part of opioid dependence. The purpose is to study the extent to which stress and other factors, including money and amount of work effort, affect opioid choice. Specifically, the investigators will examine the effects of three issues/factors. The first is how hard participants are willing to work to obtain an opioid drug; the second is how much opioid drug would participants choose instead of money; and the third factor is how much participant's opioid drug choices are influenced after they are administered the drugs yohimbine and hydrocortisone, both of which could produce stress-like symptoms.
Effective Treatment of Hepatitis C in Substance Users
Hepatitis COpiate DependenceWe hypothesize that integrating Hepatitis C into methadone and buprenorphine treatment will improve Hepatitis C outcomes as well as drug treatment outcomes in patients who are addicted to opiates. We will test this hypothesis by randomly assigning patients to receive integrated or separated care. The first group will receive Hepatitis C treatment and substance abuse treatment contemporaneously at the South Central Rehabilitation Center (SCRC). They will take both methadone or buprenorphine and Hepatitis C medications under the daily (methadone) or weekly (buprenorphine) observation of a health care provider. The second group will receive substance abuse treatment at SCRC, and go to another facility to receive Hepatitis C treatment services. These participants will take their medications on their own (without observation). We will look at outcomes such as Hepatitis C viral loads, adherence to medications, and drug treatment outcomes such as receipt of buprenorphine and methadone and urine toxicology testing.
Treatment Study: Reducing Cocaine/Heroin Abuse With SR-Amphetamine and Buprenorphine (ARC)
Heroin DependenceOpioid-Related Disorders1 moreThis research study takes place at Wayne State University and will take about 11 weeks to complete. This is a treatment research study for individuals who currently have cocaine abuse or dependence, and who may also have heroin dependence. The purpose of this study is to test whether oral sustained release d-amphetamine (SR-AMP) is safe and more effective than placebo for preventing relapse to cocaine use for individuals who abuse or are dependent upon cocaine. We are also interested whether, for patients who are dependent on cocaine and heroin, whether SR-AMP is safe and effective for preventing cocaine relapse in combination with buprenorphine.

Assessing Opioid Care Practices Using CPV Patient Simulation Modules
PainPain8 moreThis study will test the quality of opioid-related physician care decisions using a patient-simulation based measurement and feedback approach that combines multiple-choice care decisions with real-time, personalized scoring and feedback. The cases and feedback have been designed to align with the latest CDC opioid guidelines. The study will also measure the impact of gaming-inspired competition and motivation, including a weekly leaderboard, to improve evidence-based care decisions. The quality of care decisions will be measured in the simulations and in a multiple-choice assessment administered before and after the patient simulations.
Prevalence and Predictors of Prolonged Post-surgical Opioid Use: a Prospective Observational Cohort...
Opioid Use DisordersOpioid-related Disorders5 morePost-surgical opioid prescribing intended for the short-term management of acute pain may lead to long-term opioid use, and its associated harms. This study was undertaken to determine the prevalence of prolonged post-surgical opioid use, and patient-related factors associated with prolonged post-surgical opioid use.
Variation of COMT Val158Met Polymorphism Between COM-ON Patients and METHADOSE Patients
Opioid-related DisordersOpiate Dependence2 moreThe main objective is to compare the genotypes of the COMT Val158Met polymorphism between opiate-users and opiate-dependent subjects. The secondary objective is to constitute a sample of opiate-users without any lifetime opiate dependence.
Interferon-free Antiviral Treatment of Chronic Hepatitis C Virus Infection Among Opioid-substituted...
Hepatitis CChronic1 moreThe primary objective of study will be to evaluate the effectiveness of interferon-free direct acting antivirals (IFN-free DAAs) in the treatment of chronic hepatitis C virus (HCV) among patients in opioid-substitution treatment (OST). We hypothesize that rates of sustained virological response will be comparable to non-OST populations. Secondary objectives include the evaluation of safety data, patients' adherence and patient reported outcome measures like functioning (disability), satisfaction with the treatment, health status, general health perceptions and health-related quality of life.
Impact of Pregnancy on Buprenorphine Pharmacokinetics and Pharmacodynamics
Opiate AddictionPregnancyThe primary purpose of this study is to determine whether buprenorphine and metabolite exposure (reflected as the dose-adjusted plasma concentration x time curve [AUC]) differs during pregnancy and between pregnancy and the postpartum state.The study will define the pharmacokinetics of buprenorphine and determine if there is a better way to gauge dosing based on objective, physiological parameters of satiety. The study will define neonatal exposure to buprenorphine through breast milk.
