Purpose: To examine the markers of intravascular microinflammation and thickness of the intimae-media complex (IMT) of the carotid arteries in healthy individuals with reference to psychoemotional disorders. Methods: A cohort of 173 healthy individuals, age range from 30 to 60, were examined for a psychoemotional state on a hospital anxiety and depression scale. The symptoms of depression, anxiety and asthenia were accumulated to make up an index of psychoemotional disorders (PED). The level of C-reactive protein (CRP) and cytokines: tumor necrosis factor alpha (TNF-α), interleukins (IL) -1, -4, -8, have been studied by enzyme immunoassay test systems (SeroELISA, DSL, USA). The IMT of the carotid arteries was determined with the help of apparatus Aloka 5000 with 07-10 MHz linear transducer in B-mode. Results: All subjects were split into 2 groups with and without psychoemotional disorders. Group 1 consisted of 98 people (45 men and 53 women, average age 43,9±0,9). The anxiety symptoms were found in 59 subjects (60,2%), depression - in 68 (69,4%), asthenia - in 74 (75,5%) of the group. Average index of PED in this group was 3,8±0,1 points. Group 2 included 75 individuals (32 men and 43 women, average age 42,1±0,8, p1-2=0,32) with no psychoemotional disorders. IMT in group 1 was 0,81±0,02 mm, in group 2 - 0,62±0,01 mm (p=0,001). Besides, group 1 was characterized by higher levels of CRP (3,70±0,01 mcg/ml) versus group 2 (1,01±0,04 mcg/ml, p=0,01). Group 1 has also demonstrated an increase of proinflammatory cytokines: IL-1 - 28,0±3,1 pg/ml, IL-8 - 271,8±57,3 pg/ml, TNF-α - 74,7±8,9 pg/ml compared to group 2 (p=0,03-0,001). Correlation analysis of the data indicated a close link between psychoemotional factors and inflammatory markers in group 1. Thus the amount of CRP is directly correlated to the level of anxiety (r=0,51, p<0,05) and asthenia (r=0,46, p<0,05). TNF-α is correlated to severity of depression (r=0,56, p<0,05) and anxiety (r=0,39, p<0,05) level. The research revealed direct correlation between IMT and depressive symptoms (r=0,65, p<0,05) and the degree of anxiety (r=0,74, p<0,05). However, these significant correlations were not found in group 2. Conclusions: The individuals with psychoemotional disorders have shown an increase in blood concentrations of markers of intravascular microinflammation and increased carotid IMT. The symptoms of depression and anxiety identified in these individuals are directly correlated to inflammatory markers and IMT.
