Features of the course of the disease, quality of life and cytokine profile in patients with psoriasis vulgaris in the stationary stage and comorbid depression

Abstract

Aim. To study the characteristics of the course of the disease, quality of life and cytokine profile in patients with psoriasis vulgaris in the stationary stage and depression.Material and methods. A prospective, cross-sectional comparative study involved 154 patients with vulgar psoriasis in the stationary stage; Of these, two groups were formed: 83 patients with comorbid depression and 71 without comorbid depression. The Hamilton scale was used to determine depressive symptoms and severity.Result. Patients with psoriasis vulgaris in the stationary stage and depression were characterized by a younger age (p=0.007), a more severe course of the disease according to the PASI index (p<0.001), visual analogue scale (p=0.014), and a higher frequency of relapses (p=0.012) and a lower level of quality of life according to the DLQI questionnaire (p<0.001), as well as higher values of IL-6 and IL-17 in the blood serum (p=0.011; p=0.001, respectively). An inverse correlation was established between the average total value on the Hamilton scale and the age of the patients (r= –0.61; p=0.002), a direct one – with the average total values on the PASI index (r=0.72; p=0.001), visually analogue scale (r=0.63; p<0.001), DLQI (r=0.69; p=0.001) and IL-17 (r=0.62; p=0.012).Conclusion. In patients with depression, psoriasis vulgaris in the stationary stage is more severe, accompanied by an increase in systemic proinflammatory changes and a more significant decrease in quality of life than in patients without depression. The results obtained must be taken into account when choosing a therapeutic strategy for psoriasis vulgaris, which will personalize treatment and increase its effectiveness.
