To determine factors of innate and acquired immunity in adaptation disorders with a predominance of asthenic or anxiety-depressive syndrome. Twenty-five patients with ICD-10 diagnosis of «Adaptation Disorders» (F43.2), including 9 with asthenic syndrome and 16 with anxiety-depressive syndrome, were examined. The control group consisted of 23 healthy individuals. The relative number of lymphocyte phenotypes was determined by flow cytometry; the concentration of IgM, IgG, IgA, aAB to S100b and MBP - by ELISA; CIC level - by the method of selective precipitation with PEG-6000; phagocytic activity of neutrophils by a test system with melamine-formaldehyde latex; activities of leukocyte elastase (LE) and α1-proteinase inhibitor (α1-PI) by a spectrophotometric method. There were significant changes in the parameters of acquired immunity in the group with asthenic syndrome and those of innate immunity in the group with anxiety-depressive syndrome. find more An increase in α1-PI activity, in the total number of significa the course of adaptation disorders. To study the diagnostic potential of brain-derived neurotrophic factor (BDNF) and vascular endothelial growth factor (VEGFA) and their high affinity receptors (TrkB, VEGFR2) in the development and progression of diabetic polyneuropathy. The main group consisted of 65 patients with diabetes mellitus and confirmed DPN. The comparison group included 14 people with diabetes mellitus without DPN. The control group consisted of 15 healthy individuals. Clinical characteristics of DPN were evaluated with VAS, PainDetect, TSS, NSS, NDS scores. The degree of polyneuropathy was verified by electroneuromyography. Serum levels of the growth factors and their receptors were studied using enzyme-linked immunosorbent assay. Elevated expression of serum BDNF, VEGFA and TrkB was found in patients with DPN, regardless of the presence of symptoms. The severe stage of DPN is characterized by painless form of polyneuropathy, the deficiency of serum BDNF, VEGFA and VEGFR2 and the high serum level of TrkB. The high expression of BDNF affects the intensity of neuropathic pain, the severity of the clinical signs of DPN and is associated with the severity of axonal damage to sensory nerve fibers. The increase in the TrkB level is associated with the painless form of neuropathy and the degree of nerve fiber demyelination. Enhanced serum expression of BDNF and VEGFA is proposed as a biomarker for the development of DPN, while different concentrations of TrkB and VEGFR2 receptors can be considered as predictors of DPN severity. Enhanced serum expression of BDNF and VEGFA is proposed as a biomarker for the development of DPN, while different concentrations of TrkB and VEGFR2 receptors can be considered as predictors of DPN severity. To clarify a role of distinct factors that form the morphological basis of the classical or primary Chiari type 1 malformation (CM1) in the development of its clinical manifestations and subtypes. The main study group included 710 adult patients with cerebellar ectopia divided into subgroups according to the severity of cerebellar ectopia (less than 2 mm (CM0); 2-4 mm (CM0,5); 5 mm or more (CM1); 5 mm or more in combination with a pronounced prolapse of the brain stem below the foramen magnum (CM1,5)) as well as to the presence of «overcrowded» posterior cranial fossa (PF) and «small» PF. Clinical symptoms and bone phenotype of PF were analyzed. With an increase of the degree of cerebellar tonsils ectopia, an increase in the proportion of patients with «overcrowded» PF, syringomyelia, otoneurological and lower cranial nerve, brain stem, cerebellar disturbances was revealed. The phenomenon of «small» PF was observed in 81% of the main group. «Small» PF was associated with a greater proportion of patientsmena in the diagnostic algorithm for patients with suspected Chiari malformation
