MicroRNA hsa-miR-370-3p is a new biomarker for assessing the level of CYP2D6 gene expression, as well as the clinical efficacy and safety of mirtazapine in patients with depressive disorders comorbid with alcohol use disorder

Abstract

The study of the effect of CYP2D6 gene polymorphism on the efficacy and safety of mirtazapine therapy in patients with depressive disorders comorbid with alcoholism was carried out. In a group of 106 patients with depressive disorders comorbid with alcohol dependence, the effect of the 1846G> A polymorphism of the CYP2D6 gene (rs3892097) on the safety profile of mirtazapine was demonstrated, but not on the effectiveness. At the same time, hsa-miR-370-3p remains a promising biomarker for assessing the level of CYP2D6 gene expression, since the level of its plasma concentration differed in carriers of different genotypes for the polymorphic marker 1846G> A, although no connection with clinical efficacy and safety was found.
