We performed immunophysiological examination of 144 men aged 17-25 years, patients with psychoactive substance dependence, episodic psychoactive drug users, and conditionally healthy individuals. Associations of proinflammatory cytokine production with age, sex, hormone levels, and olfactory and nociceptive indices were revealed in cases of psychoactive drug use and formation of addiction. Predictive models based on the use of androstenone aversion, pressure algometry testing, and immunological parameters were proposed.
The aim of the study is to search for biomarkers of risk and prevention of the formation of alcohol dependence on the background of depression. Antibodies are evaluated for a number of neurotransmitters, the information content of which is confirmed by preliminary studies. Materials and methods. Autoantibodies to dopamine, norepinephrine, 5-hydroxytryptamine, glutamate, gamma-aminobutyric acid were determined by ELISA in 60 controls and patients with depression and alcohol use disorder (AUD). Results. The level of antibodies to all studied neurotransmitters decreases with depression, especially complicated by alcoholism. An exception is the level of antibodies to serotonin, which increases with AUD and depression combined with AUD. Conclusion. It is assumed that this type of reaction may be a biomarker of the risk of alcoholism in depression.
The data obtained may provide background for unification of reward circuit and inhibitory control concepts in regulation of addictive behavior. (Am J Addict 2017;26:640-648).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
