CHN2 Promoter Methylation Change May Be Associated With Methamphetamine Dependence.

Methamphetamine (MA) abuse is becoming increasingly serious in China. The mechanism of MA dependence remains unclear. CHN2 gene encodes chimeric protein-2 that regulate axonal pruning via the Rac-GTPase system and play a pivotal role in the formation of nervous circuits. Genetic studies suggest that the polymorphism of the CHN2 gene was related to substance dependence.


Buspirone maintenance does not alter the reinforcing, subjective, and cardiovascular effects of intranasal methamphetamine.

Medications development efforts for methamphetamine-use disorder have targeted central monoamines because these systems are directly involved in the effects of methamphetamine. Buspirone is a dopamine autoreceptor and D3 receptor antagonist and partial agonist at serotonin 1A receptors, making it a logical candidate medication for methamphetamine-use disorder. Buspirone effects on abuse-related behaviors of methamphetamine have been mixed in clinical and preclinical studies. Experimental research using main...

Methamphetamine use and future risk for Parkinson's disease: Evidence and clinical implications.

Methamphetamine use has been posited to be a risk factor for the development of Parkinson's disease (PD) and parkinsonism. The clinical implications of a potential association between methamphetamine use and PD are considered.


The effect of N-acetylcysteine or bupropion on methamphetamine self-administration and methamphetamine-triggered reinstatement of female rats.

N-acetylcysteine and bupropion are two promising candidate medications for treatment of substance use disorder. The effects of N-acetylcysteine or bupropion on methamphetamine self-administration of female rats are not well understood. To fill this gap, this study assessed the effects of N-acetylcysteine (0, 30, 60, or 120 mg/kg) and bupropion (0, 10, 30, and 60 mg/kg) on methamphetamine self-administration of female rats across the natural estrous cycle. Following a completed dose-response curve, respo...

Impulsivity predicts poorer improvement in quality of life during early treatment for people with methamphetamine dependence.

Methamphetamine dependence is associated with heightened impulsivity and diminished quality of life, but the link between impulsivity and changes in quality of life during treatment has not been examined. We aimed to investigate how different elements of impulsivity predict change in quality of life in the six weeks after engaging in treatment.

The impact of acute and short-term methamphetamine abstinence on brain metabolites: A proton magnetic resonance spectroscopy chemical shift imaging study.

Abuse of methamphetamine (MA) is a global health concern. PreviousH-MRS studies have found that, with methamphetamine abstinence (MAA), there are changes in n-acetyl-aspartate (NAA/Cr), myo-inositol (mI/Cr), choline (Cho/Cr and Cho/NAA), and glutamate with glutamine (Glx) metabolites. Limited studies have investigated the effect of acute MAA, and acute-to-short-term MAA on brain metabolites.

Social cognition and aggression in methamphetamine dependence with and without a history of psychosis.

In substance use and psychotic disorders, socially problematic behaviours, such as high aggression may, in part, be explained by deficits in social cognition skills, like the detection of emotions or intentions in others. The aim of this study was to assess the magnitude of social cognition impairment and its association with aggression in individuals with methamphetamine (MA) dependence, methamphetamine-associated psychosis (MAP), and healthy controls (CTRL). A total of 20 MAP participants, 21 MA-dependent...

Relationship between the duration of methamphetamine use and psychotic symptoms: A two-year prospective cohort study.

Psychosis is a key harm associated with methamphetamine (MA) use. This study examined the relationship between the duration of MA use and risk of psychotic symptoms.

Crystal methamphetamine use and its correlates in women engaged in sex work in a developing country setting.

Worldwide, crystal methamphetamine (CM) use and associated high-risk sexual behaviors are a concern, but they are less studied among female sex workers (FSW) in developing countries. This study aimed to characterize the prevalence and individual, interpersonal, and structural correlates of self-reported past-month CM use among FSW in Iran.

Methamphetamine-associated dysregulation of the hypothalamic-pituitary-thyroid axis.

Methamphetamine and HIV impair thyroid function, but few studies have investigated their combined effects on thyroid dysregulation. This study examined the associations of methamphetamine use alone and in combination with HIV on thyroid function among men in South Florida. Measures of thyroid function in methamphetamine-using, HIV-infected (METH+HIV+; n = 127) and HIV-negative (METH+HIV-; n = 46) men who have sex with men (MSM) were compared to non-methamphetamine-using, HIV-negative men (METH-HIV-;...

The relationship between impulsivity and methamphetamine use severity in a community sample.

Abuse of psychostimulants, including methamphetamine (MA), has been linked to heightened impulsivity. While previous research has demonstrated differences in impulsivity between MA users and non-substance users, less is known about variability in impulsivity within MA users and whether the severity of MA use related problems predicts impulsivity within individuals who regularly use MA. This study aims to elucidate the relationship between impulsivity and MA use severity.

Cognitive Deficits in Methamphetamine Users: How Strong is The Evidence?

Methamphetamine use has spread in many European countries and the United States. The current review provides a summary and critical analysis of research on cognitive deficits associated with methamphetamine, also known as "crystal meth." The literature search performed for this review led us to the hypothesis that methamphetamine use is associated with persistent changes in brain metabolism that result in various impairments, such as deficits in memory, attention, and concentration. The dopaminergic system ...

Involvement of dopamine D2 receptor in a single methamphetamine-induced behavioral sensitization in C57BL/6J mice.

A single exposure to drugs of abuse is sufficient to induce behavioral sensitization, which is a form of long-lasting neuroplasticity. Dopamine D2 receptors are the main receptor for antipsychotic drugs, but little is known about their role in a single methamphetamine-induced behavioral sensitization. In the present study, we examined whether typical antipsychotic haloperidol and atypical antipsychotic risperidone, both targeting dopamine D2 receptor, could prevent the methamphetamine sensitization when the...

HIV treatment optimism and crystal methamphetamine use and initiation among HIV-negative men who have sex with men in Vancouver, Canada: A longitudinal analysis.

Treatment as Prevention (TasP) leading to increased HIV treatment optimism among men who have sex with men (MSM) has been previously associated with behavioural risk compensation, though not yet via crystal methamphetamine (CM) use. Among HIV-negative MSM in a TasP environment, this study aimed to investigate the prevalence of recent CM use over time, examine the association between HIV treatment optimism and CM use and initiation, and identify correlates of recent CM use and predictors of CM initiation.

Non-occlusive Mesenteric Ischemia in Patients with Methamphetamine Use.

Data suggest that methamphetamine may increase the risk of non-occlusive mesenteric ischemia (NOMI). We describe patterns of presentation and outcomes of patients with methamphetamine use who present with NOMI to a single institution.

CDP-choline protects liver from ischemia/reperfusion injury preserving mitochondrial function and reducing oxidative stress.

CDP-choline (citicoline) participates as intermediary in the synthesis of phosphatidylcholine, an essential component of cellular membranes. Citicoline treatment has shown beneficial effects in cerebral ischemia, but its potential to diminish reperfusion damage in liver has not been explored. In this work, we evaluated the hepatoprotective effect of citicoline and its possible association with inflammatory/oxidative stress and mitochondrial function, as they are main cellular features of reperfusion damage....

Effect of methamphetamine exposure on the plasma levels of endothelial-derived microparticles.

Methamphetamine (Meth), a neurotoxin, induces inflammation, oxidative stress, and triggers endothelial dysfunction and cardiovascular disease which is the second cause of death among individuals with Meth-use disorder. Oxidative stress and inflammation trigger the microparticle (MP) release. These are extracellular vesicles extracted from cell surface and identified in biological fluids. MP levels alter during pathological conditions, suggesting its potential biomarker role. In this respect, we designed the...

How treatment improvement in ADHD and cocaine dependence are related to one another: A secondary analysis.

Attention-deficit hyperactivity disorder (ADHD) is overrepresented among individuals seeking treatment for substance use disorders. We previously reported that treatment with extended release mixed amphetamine salts (MAS-XR) increased abstinence, compared to placebo, among patients with co-occurring ADHD and cocaine dependence. This secondary analysis investigates the temporal relationship between ADHD improvement and cocaine abstinence in the first six weeks of the trial.

Cognitive deficit In methamphetamine users relative to childhood academic performance: Link to cortical thickness.

Individuals with cognitive problems may be predisposed to develop substance use disorders; therefore, differences in cognitive function between methamphetamine users and control participants may be attributable to premorbid factors rather than methamphetamine use. The goal of this study was to clarify the extent to which this is the case. Childhood academic transcripts were obtained for 37 methamphetamine-dependent adults and 41 control participants of similar educational level and premorbid IQ. Each partic...

Factors Influencing Transition to Shisheh (Methamphetamine) among Young People Who Use Drugs in Tehran: A Qualitative Study.

Iran has experienced an emerging epidemic of methamphetamine use during recent years which has added to existing non-injecting and injecting opioid use in the country. This study explored factors influencing the initiation into or transition to methamphetamine use among young people who use drugs (PWUD).

New Scaffold for Lead Compounds to Treat Methamphetamine Use Disorders.

Despite increased methamphetamine use worldwide, pharmacotherapies are not available to treat methamphetamine use disorder. The vesicular monoamine transporter-2 (VMAT2) is an important pharmacological target for discovery of treatments for methamphetamine use disorder. VMAT2 inhibition by the natural product, lobeline, reduced methamphetamine-evoked dopamine release, methamphetamine-induced hyperlocomotion, and methamphetamine self-administration in rats. Compared to lobeline, lobelane exhibited improved a...

Methamphetamine-induced impulsivity during chronic methamphetamine treatment in rats: Effects of the TAAR 1 agonist RO5263397.

Impulsivity is an important personality trait associated with several clinical syndromes including drug abuse. While repeated drug exposure is known to increase certain behavioral responses, such as locomotion, to subsequent drug exposure, few studies have examined whether such sensitization develops for impulsive behavior. In the current study we tested the effects of methamphetamine acutely, during the course of, and upon discontinuation of chronic methamphetamine treatment on impulsive behavior in two mo...
