The effect of brain neurotrophic factor gene polymorphism on the effectiveness of therapeutic and rehabilitation measures in patients with psychostimulant dependence

Justification. Along with the rising consumption of psychostimulants, the number of patients with dependence on psychostimulants is increasing all over the world and in Russia in particular. At the same time, the number of patients with dependence on drug combinations is increasing, most of which are psychostimulants. Aim. The aim of the work is to develop a personalized approach to the therapy of patients with dependence on psychostimulants, taking into account the polymorphism of the neurotrophic factor gene of the brain. Material and methods. 305 patients with dependence on psychostimulants, men and women from 18 to 50 years old, were studied. Depending on the drug used and their combinations, as well as the presence of comorbid psychiatric pathology, all patients were divided into 6 groups. Research methods: molecular-genetic, clinical-psychopathological, catamnestic, statistical (parametric and nonparametric methods using Statistica 10.0 programs of STAT Soft Inc., USA). The effect of polymorphism of the neurotrophic factor gene of the brain on the effectiveness of therapeutic and rehabilitation measures in patients in different groups was evaluated. Results. It was found that patients who use only psychostimulants and psychostimulants with cannabinoids, having a homozygous (GG) genotype of the neurotrophic factor gene of the brain, are longer in the rehabilitation program and have the longest remissions. Conclusion. Polymorphism of the neurotrophic factor gene of the brain affects the effectiveness of therapeutic and rehabilitation measures in patients with dependence on psychostimulants.
