Abstract
The role of psychological factors in the manifestation and exacerbation of psoriasis is well known. Acute and chronic stress, anxiety, and depression affect the reactions of innate and acquired immunity. The exacerbations of psoriatic lesions are accompanied by increased production of inflammatory mediators, which could contribute to the imbalance of neurotransmitters and the development of symptoms of depression and anxiety. The role of inhibitory neurotransmitters in the serum of patients with psoriasis exacerbation with comorbid emotional disorders is assessed. Forty patients with psoriasis in the exacerbation stage were examined. Spielberger State-Trait Anxiety Inventory (STAI) and the Beck Depression Inventory (BDI) scale were used to assess anxiety and depression parameters. We also evaluated the concentration of serotonin and gamma-aminobutyric acid (GABA) in the serum. Patients with psoriasis had significant anxiety and depressive disorders. An imbalance in serotonin levels and a decrease in serum GABA levels in patients with psoriasis in the acute stage were noted. Only patients with anxiety disorder had increased serotonin levels. Our findings suggest that the imbalance of neurotransmitters in patients with psoriasis in the acute stage is important in predicting the development of the emotional well-being.
