Project description:Heroin addiction and withdrawal influence multiple physiological functions including immune responses, but the mechanism remains largely elusive. The objective of this study was to investigate the immune system function and molecular inflammatory interactome particularly the cytokines and RNA regulatory network in heroin addicts undergoing withdrawal compared healthy controls.

Project description:OBJECTIVE:To investigate the manifestations and incidence of headaches caused by heroin in Chinese women. METHODS:This was a survey study conducted from 29 June to 3 July 2015 with women attending the Shanxi Drug Rehabilitation Centre for Women (China). All study subjects were newly admitted and had not begun their drug rehabilitation. Demographic characteristics, heroin usage and headache episodes within the previous 3 months were surveyed, especially the presence of a headache within 2 hours of heroin use. Details of the severity, location, premonitory symptoms and characteristics of headaches were recorded. RESULTS:Of the 90 heroin-dependent patients, 74 experienced headache attacks within 2 hours of heroin use, and the headaches subsided within 72 hours of discontinuation of heroin use. Most heroin-induced headaches were similar to migraines and manifested as pulsating pain in 54 patients (51/74, 68.9%); bilateral pain was reported by 46 patients (46/74, 62.2%). Approximately half of the patients with heroin-induced headaches also reported accompanying symptoms of nausea, vomiting, and light and sound sensitivity. CONCLUSIONS:Heroin-induced headache may eventually be listed as a new class of headache in the International Classification of Headache Disorders.

Project description:BackgroundHeroin addiction and withdrawal have been associated with an increased risk for infectious diseases and psychological complications. However, the changes of metabolites in heroin addicts during withdrawal remain largely unknown.MethodsA total of 50 participants including 20 heroin addicts with acute abstinence stage, 15 with protracted abstinence stage and 15 healthy controls, were recruited. We performed metabolic profiling of plasma samples based on ultraperformance liquid chromatography coupled to tandem mass spectrometry to explore the potential biomarkers and mechanisms of heroin withdrawal.ResultsAmong the metabolites analyzed, omega-6 polyunsaturated fatty acids (linoleic acid, dihomo-gamma-linolenic acid, arachidonic acid, n-6 docosapentaenoic acid), omega-3 polyunsaturated fatty acids (docosahexaenoic acid, docosapentaenoic acid), aromatic amino acids (phenylalanine, tyrosine, tryptophan), and intermediates of the tricarboxylic acid cycle (oxoglutaric acid, isocitric acid) were significantly reduced during acute heroin withdrawal. Although majority of the metabolite changes could recover after months of withdrawal, the levels of alpha-aminobutyric acid, alloisoleucine, ketoleucine, and oxalic acid do not recover.ConclusionsIn conclusion, the plasma metabolites undergo tremendous changes during heroin withdrawal. Through metabolomic analysis, we have identified links between a framework of metabolic perturbations and withdrawal stages in heroin addicts.

Project description:Noncoding RNAs, especially microRNAs (miRNAs) have been implicated in the regulation of neuronal functions, such as learning, cognition and memory formation. However, the particular miRNAs involved in drug-induced behavioral plasticity are largely unknown. Here we report a novel regulator, miR-218, that inhibits heroin-induced behavioral plasticity. Network propagation-based method revealed several miRNAs that play key roles in drug-addiction, among which, miR-218 was decreased in nucleus accumbens (NAc) after chronic exposure to heroin. Lentiviral overexpression of miR-218 in NAc could inhibit heroin-induced reinforcement in both conditioning place preference (CPP) test and heroin self-administration (SA) experiment. Luciferase activity assay indicated miR-218 could regulate neuroplasticity related genes and directly target Mecp2 3’UTR. Consistently, Mecp2-/y mice exhibited reduced heroin seeking behavior in CPP test. These data reveal a functional role of miR-218 and its target, Mecp2, in the regulation of heroin-induced behavioral plasticity.

Project description:Several studies have investigated changes induced by drug exposure, but few reports have described changes that persist following relapse. In the present study, genome-wide analysis of gene expression was conducted in rats that expressed behavioral incubation of heroin-seeking and goal-directed behavior. The medial prefrontal cortex (mPFC) is important in mediating goal-directed behavior and also was the target of this analysis. Rats were trained to self-administer heroin (0.06 mg/0.2 ml infusion) during 3 hour daily sessions for 14 days. Following the self-administration period, rats were reintroduced to the self-administration chambers for a 90-minute extinction session. The extinction session occurred either 1 day or 14 days following the final self-administration session. Behavioral data demonstrated incubation (increased expression) of heroin-seeking and goal-directed behavior after the 14 day abstinent period. Whole genome analysis was performed and selected results were confirmed by quantitative real-time PCR (RT-qPCR). Microarrays identified 66 genes whose expression was identified as changed by at least 1.4 fold (p<0.02) following 14 days of abstinence and the 90-minute extinction session, and seven of the genes on which RT-qPCR was performed were confirmed (BDNF, Calb1, Dusp5, Dusp6, EGR1, NPY, RGS2). Ontological analysis indicates that several of the genes with changed expression in this study are important for behavior and learning. The importance of drug-seeking behavior and memory of previous sessions of drug-taking suggest that such genes may be important for relapse. The global gene expression analysis adds to the knowledge of heroin-induced changes and further highlights similarities between heroin and other drugs of abuse. Keywords: heroin self-administration cRNA from 6 rats that self-administered heroin was compared to cRNA from 5 rats that received yoked infusions of saline.

Project description:To identify molecular effects of chronic drug treatment, heroin and methamphetamine treated animals were compared with saline treated animals at multiple time-points using microarray technology. Gene expression profile was assessed 14 h after the last dose of 1, 3, 6 or 12 days drug treatment and after 13, 15, 18 or 24 days of withdrawal. Animals were injected intraperitoneally with saline (SAL) (Polfa, Lublin, Poland), heroin (synthesized from morphine in Institute of Pharmacology PAS, Krakow, Poland) or D-methamphetamine (Sigma-Aldrich, Poznan, Poland) twice a day for consecutive 12 days in increasing doses. The Methamphetamine last dose (8 mg/kg) was four times greater than the first dose (2 mg/kg). It was also the case for heroin (40 and 10 mg/kg respectively). Mice were sacrificed by decapitation after 1, 3, 6 or 12 days of treatment or after 13, 15, 18 or 24 days of withdrawal.

Project description:Whether methadone maintenance treatment (MMT) can improve the basal function of the hypothalamic-pituitary-adrenal (HPA) axis, which is suppressed by long-term heroin consumption, is a matter of debate. The stress state and depression and anxiety symptoms may affect the basal activity of the HPA axis in MMT patients. However, the effect of psychological factors on HPA activity was not simultaneously controlled in previous studies. This study investigated differences in HPA basal activity between MMT patients and controls using psychological variables as covariates. The participants included 52 MMT patients and 41 age-matched, non-heroin-dependent controls. Psychological states were self-reported with the Perceived Stress Scale, Self-Rating Depression Scale and Self-Rating Anxiety Scale. The hair cortisol level was adopted as a biomarker of HPA basal activity and was determined with liquid chromatography tandem mass spectrometry. The results revealed that MMT patients had significantly higher hair cortisol levels than the controls (p<0.05), but the difference was not significant (p>0.05) when the perceived stress, depression and anxiety scores were used as covariates. We concluded that patients with long-term MMT showed higher basal activity of the HPA axis. The high chronic stress state and increase in depression and anxiety symptoms may mask the suppression effect of methadone on the HPA activity.
