The article discusses a new hypothesis that autoimmune diseases of the thyroid gland can lead to depression and neurological complications. It is believed that the neuronal N-methyl-D-aspartate receptor plays a significant role in depression pathophysiology and neurological and mental diseases, respectively. The study involved 153 patients with various forms of thyroid pathology. GRIN2B levels in the sera of the patients and healthy individuals were quantified using enzyme-linked immunosorbent assay with highly sensitive Human GRIN2B (Glutamate Receptor, Ionotropic, N-Methyl-D-Aspartate 2B) ELISA Kit. Genotyping of the glutamate ionotropic receptor NMDA type subunit 1, GRIN1 (rs4880213) gene polymorphism. The CT genotype of the NMDA gene (rs4880213) was predominant in the surveyed population. The C allele of the NMDA gene was more frequent than the T allele among patients with thyroid disease. GRIN2B levels were significantly decreased in patients with postoperative hypothyroidism 3.45 times, and in patients with AIT-induced hypothyroidism, there was a probable increase in GRIN2B levels by 1.58 times compared with controls. GRIN2B levels were significantly different in patients of different groups depending on thyroid pathology. Our study showed direct close correlation (r=0.635) between GRIN2B and anti-TPO levels (p<0.001), a significant direct close correlation (r=0.527) between GRIN2B and anti-TG levels in the blood (p<0.001). Our results allow us to consider the GRIN2B level as an important prognostic minimally invasive marker of neurological complications in endocrine pathology. ©2022 JOURNAL of MEDICINE and LIFE.
