Different immunotherapeutic approaches are in the pipeline for the treatment of drug dependence. "Drug vaccines" aim to induce the immune system to produce antibodies that bind to drugs and prevent them from inducing rewarding effects in the brain. Drugs of abuse currently being tested using these new approaches are opioids, nicotine, cocaine, and methamphetamine. In human clinical trials, "cocaine and nicotine vaccines" have been shown to induce sufficient antibody levels while producing few side effects. Studies in humans, determining how these vaccines interact in combination with their target drug, are underway...

Chemotherapy-Induced Peripheral Neuropathy (CIPN) is the most frequent adverse effect of pharmacological cancer treatments. The occurrence of neuropathy prevents the administration of fully-effective drug regimen, affects negatively the quality of life of patients, and may lead to therapy discontinuation. CIPN is currently treated with anticonvulsants, antidepressants, opioids and non-opioid analgesics, all of which are flawed by insufficient anti-hyperalgesic efficacy or addictive potential. Understandably, developing new drugs targeting CIPN-specific pathogenic mechanisms would dramatically improve efficacy and tolerability of anti-neuropathic therapies...

Commonalities in addictive behavior, such as craving, stimuli-driven drug seeking, and a high propensity for relapse following abstinence, have pushed for a unified theory of addiction that encompasses most abused substances. This unitary theory has recently been challenged - citing distinctions in structural neural plasticity, biochemical signaling, and neural circuitry to argue that addiction to opioids and psychostimulants is behaviorally and neurobiologically distinct. Recent more selective examination of drug-induced plasticity has highlighted that these two drug classes promote an overall reward circuitry signaling overlap through modifying excitatory synapses in the nucleus accumbens - a key constituent of the reward system...

BACKGROUND: Chronic pain is common in the United States and prescribed opioid analgesics use for noncancer pain has increased dramatically in the past two decades, possibly accounting for the current opioid addiction epidemic. Co-morbid drug use in those prescribed opioid analgesics is common, but there are few data on polysubstance use patterns. OBJECTIVE: We explored patterns of use of cigarette, alcohol, and illicit drugs in HIV-infected people with chronic pain who were prescribed opioid analgesics...

Pregnancy can be a motivation for decrease in drug abusing but may also represent a period of high vulnerability for relapse.We aimed to assess psychoactive substance use among women with substance use disorders followed in addiction care centers in France. We analyzed data from women aged 15-44 years included in the 'Observation of illegal drugs and misuse of psychotropic medication survey' (OPPIDUM), an annualcross-sectional survey collecting details on psychoactive substances used. Characteristics of women included in 2005 to 2012 yearly surveys were compared depending on their pregnant or not pregnant status...

Preclinical and clinical studies have demonstrated that the kappa opioid receptor (KOR) regulates reward, hedonic tone and emotions. At therapeutic level, on-going clinical trials are assessing the potential of targeting the KOR for the management of depression, anxiety disorders and substance use disorders. However, genetic polymorphisms in the KOR gene that potentially contribute to its implication in these phenotypes have been poorly studied. Here we investigated an insertion-deletion in the promoter region of KOR (rs35566036), recently associated with alcohol addiction, in a cohort of depressed subjects who died by suicide, as well as psychiatrically healthy individuals...

BACKGROUND: Currently, no pharmacogenetic tests for selecting an opioid-dependence pharmacotherapy have been approved by the US Food and Drug Administration. OBJECTIVES: Determine the effects of variants in 11 genes on dropout rate and dose in patients receiving methadone or buprenorphine/naloxone (ClinicalTrials.gov Identifier: NCT00315341). METHODS: Variants in six pharmacokinetic genes (CYP1A2, CYP2B6, CYP2C19, CYP2C9, CYP2D6, CYP3A4) and five pharmacodynamic genes (HTR2A, OPRM1, ADRA2A, COMT, SLC6A4) were genotyped in samples from a 24-week, randomized, open-label trial of methadone and buprenorphine/naloxone for the treatment of opioid dependence (n = 764; 68...

Nociceptin /Orphanin FQ Peptide" receptor (NOPr) is a G-protein-coupled receptor with the nociceptin/orphanin FQ peptide (N/OFQ) as endogenous agonist. It is expressed in the nervous system as well as in some non-neural tissues. Its activation has pronociceptive effect at the supraspinal level, whereas at the spinal level it produces nociceptive effects at low doses and antinociceptive effects at higher doses. NOPr is also involved in mood and blood pressure regulation, immunoregulation, airway constriction, feeding, urination, bowel motility, learning and memory...

Methadone is used for medication-assisted treatment of heroin addiction during pregnancy. The neurodevelopmental outcome of children with prenatal methadone exposure can be sub-optimal. We tested the hypothesis that brain development is altered among newborn infants whose mothers were prescribed methadone. 20 methadone-exposed neonates born after 37 weeks' postmenstrual age (PMA) and 20 non-exposed controls underwent diffusion MRI at mean PMA of 39+ 2 and 41+ 1 weeks, respectively. An age-optimized Tract-based Spatial Statistics (TBSS) pipeline was used to perform voxel-wise statistical comparison of fractional anisotropy (FA) data between exposed and non-exposed neonates...

Overdoses of prescription or illicit opioids claimed the lives of 116 Americans each day in 2016, and the crisis continues to escalate. As healthcare systems evolve to address the crisis, the potential of pharmacists to make a positive difference is significant. In addition to utilizing available prescription drug monitoring programs to help prevent diversion of opioids, practicing pharmacists can be alert for signs of opioid misuse by patients (e.g., multiple prescriptions from different physicians) as well as inappropriate prescribing or hazardous drug combinations that physicians may not be aware of (e...

AIM: Our aim was to compare physician-reported barriers to sublingual buprenorphine (BUP) and extended-release naltrexone (XR-NLT) prescribing in U.S. office-based practices, and to identify potential policies for minimizing these barriers. Only one previous qualitative study has examined physician-reported barriers to prescribing XR-NLT and no qualitative study has compared physician-reported barriers between the two medications. METHODS: Researchers conducted individual semi-structured and in-depth interviews with 20 licensed physicians in four U...

The United States is in the midst of an opioid use epidemic, which has severe medical, social, and economic consequences. Addictions to and abuse of prescription and illicit opioids are increasing, and emergency department radiologists are increasingly being faced with the task of examining patients who present with opioid-related complications. These complications may be the result of direct drug toxicity or nonsterile injection of the drugs. Neurologic, musculoskeletal, cardiopulmonary, genitourinary, and gastrointestinal complications may be evident at diagnostic imaging in emergent settings...

The incidence of opioid abuse and subsequent drug withdrawal is exponentially on the rise in the United States for many populations including newborns who are born to drug-addicted mothers. These newborns often exhibit symptoms of neonatal abstinence syndrome (NAS) within 24 to 72 hours of birth. Treatment of NAS includes monitoring of withdrawal symptoms, managing physiological parameters, and the use of supportive and pharmacologic treatments. Although a few randomized controlled trials exist, studies on supportive intervention are generally limited by small sample sizes, case study reports, expert opinions, and descriptive design...

Opioids are frequently prescribed for chronic pain. For the past 2 decades, long-term opioid analgesic therapy was considered the cornerstone of effective pain management for chronic nonmalignant conditions, despite a lack of documented effectiveness and safety, with the attendant risk of addiction, overdose, and death. Cognitive behavioral therapy (CBT) may be used effectively to treat chronic pain, either as a stand-alone treatment or with other nonopioid pharmacological treatments. CBT improves pain-related outcomes along with mobility, quality of life, and disability and mood outcomes...

Increased physician prescribing of opioids to treat chronic nonprogressive pain has been accompanied by an increase in opioid addiction. Twin studies of opioid addiction are consistent with an inherited component of risk, approximately 50%. Several genome-wide association study (GWAS) reports indicate that genetic risk for opioid addiction is conveyed by many alleles of small effect (odds ratios <1.5). These reports have detected alleles in potassium-ion-channel genes (KCNC1 and KCNG2) and in a glutamate receptor auxiliary protein (CNIH3)...

The opioid system is well conserved among species and plays a critical role in pain and addiction systems. The use of zebrafish as an experimental model to study development and genetics is extraordinary and has been proven to be relevant for the study of different diseases. The main drawback to its use for the analysis of different pathologies is the lack of protein tools. Antibodies that work in other models are not suitable for zebrafish due to the low degree of homology that exists among the opioid receptor protein sequences in different species...

Pain is a major symptom that causes suffering among patients diagnosed with cancer. Identifying physicians' and nurses' knowledge, attitudes, and their perceived barriers of cancer pain management is considered an essential step in improving cancer pain relief. The purposes of this study are to compare physicians' and nurses' knowledge and attitudes toward cancer pain management (CPM) and describe their perceived barriers to CPM at oncology units. A descriptive cross-sectional design was utilized to obtain data through self-report questionnaire...
