Psoriasis is a common chronic inflammatory skin condition that varies in severity. Psoriasis is associated with complex disorders, which incorporate metabolic syndrome, obesity and impaired glucose tolerance. Adipose tissue secretes several hormones and cytokines, in particular visfatin and resistin that could be involved in the development of psoriasis by acting as pro-inflammatory or immunoregulatory factors. The aim of this work was to evaluate the serum level of visfatin and resistin as well as of high-sensitivity C-reactive protein (hs-CRP) and erythrocyte sedimentation rate (ESR) in psoriatic patients. The study included 43 healthy individuals and 45 patients divided into three groups with mild, moderate and severe clinical degrees of disease assessed by the Psoriasis Area Severity Index (PASI). The results showed a significant increase in the concentration of serum visfatin, resistin, ESR and hs-CRP in patient groups in comparison with a control group. The highest increase in indicators was observed in the group of patients with severe disease compared with the mild and moderate patients groups. The significance of studied indicators as biomarkers of psoriasis disease severity is analyzed.

Methotrexate (MTX) is the immunosuppressive anti-inflammatory drug and the antagonist of the enzyme dihydrofolate reductase. Pharmacogenomic studies and clinical evidences suggest that altered response to MTX  in patients with different diseases is associated with polymorphisms of genes that regulate folate metabolism. The purpose of the article was to analyze the methotrexate effect on the biochemical indices of psoriasis patients depending on methylenetetrahydrofolate reductase gene (MTHFR) polymorphisms. Effects of two single-nucleotide polymorphisms, C677T and A1298C, were studied. An increase of alanine aminotransferase and aspartate aminotransferase activity above the normal level in the patients with both MTHFR gene polymorphisms after methotrexate intake was observed. In patients with CC, TT, CT genotypes for C677T polymorphism and AA genotype for A1298C polymorphism of MTHFR gene, significant differen­ces in alpha-amylase activity before and after treatment with methotrexate were detected. Analysis of the biochemical indices of  patients with arthropathic and vulgaris psoriasis showed that the positive effect of MTX treatment could be associated with wild-type alleles in both  polymorphisms of MTHFR gene, while the ineffectiveness of methotrexate was associated with the dihеterozygous genotype. The largest number of smokers was found within the CTAA genotype group (37.5%), while no smokers were observed within TTAA patients and most of CCAA patients. The data obtained testify the utility of the individual approach to the psoriasis patients therapy taking into account genetic background.
