Indicators of Immune and Neurohumoral Profile in Women of Fertile Age with Functional Disorders of the Autonomic Nervous System Associated with Polymorphic Variants of the HTR2A (rs7997012) and TP53 (rs1042522) Genes.

In women of fertile age with functional disorders of the autonomic nervous system (ANS), a complex of indicators of the immune and neurohumoral profile associated with polymorphic variants of the HTR2A (rs7997012) and TP53 (rs1042522) genes was revealed. In patients with the diagnosis "G90.8. Other disorders of the autonomic nervous system", the neurohumoral profile is characterized by excessive content of cortisol and serotonin (p<0.05), which indicates the development of the hypersympathicotonic variant of autonomic regulation disorders. The cellular immune profile in the examined individuals was characterized by a significant decrease in the content of CD3+CD4+ and CD3+CD8+ lymphocytes (p<0.05). At the same time hyperactivation of the humoral immune response was observed. In particular, we revealed enhanced production of IgG and IgM antibodies accompanied by increased count of CD19+ lymphocytes (p<0.05), which characterized clinical and laboratory manifestations of the asthenic syndrome. The women with ANS disorders had increased frequency of the G allele (OR=3.00; 95%CI 1.20-7.47) and GG genotype (OR=3.91; 95%CI 1.00-15.24) of the HTR2A (rs7997012) serotonin receptor gene, as well as the G allele (OR=1.93; 95%CI 1.04-3.57), CG genotype (OR=2.38; 95%CI 1.02-5.53) and the GG genotype (OR=1.48; 95%CI 0.42-5.24) of the TP53 (rs1042522) oncosuppressor protein gene (p<0.05). The polymorphic G allele and GG genotype variants of candidate genes (HTR2A (rs7997012) and TP53 (rs1042522) genes) in women with ANS pathology are associated with an imbalance of the neurohumoral (excess of cortisol and serotonin) and immune regulation (deficiency of the CD3+CD4+ and CD3+CD8+, excess of CD19+, IgG and IgM). These parameters form a complex of the immune, neurohumoral, and genetic profile indicators in women of fertile age that characterize functional disorders of ANS manifestations by hypersympathicotonic type with an asthenic component.
