BACKGROUND

Psoriasis is a common disease of skin and its appendages, affecting the visceral organs and musculoskeletal system. The annual increase in the number of patients, including with severe psoriasis, often results in an accentuated decrease in the quality of life and even disability, that dictates the necessity of search for new methods of diagnosis.

OBJECTIVE

To analyze the indicators of the body component composition in patients of mature age (the 2nd period), depending on the psoriasis severity.

MATERIAL AND METHODS

A clinical (assessment of psoriasis severity and prevalence according to PASI) bioimpedance survey of 114 men of mature age (the 2nd period) with psoriasis vulgaris has been conducted.

RESULTS

Of those examined, 20.18% had a mild psoriasis, 42.11% — a moderate-to-severe psoriasis and 37.31% — a severe psoriasis. An imbalance in the body component composition in patients with predominantly moderate-to-severe and severe disease was found. The highest body mass index (28.5±1.6 kg/m²) and the relative fat content (31.56±4.15%) were diagnosed in patients with severe dermatosis. The maximal extracellular fluid indicator was found in patients with moderate-to-severe disease (51.89±3.89%), and patients in this group had a minimum percentage of fat free mass (74.89±7.42%).

CONCLUSION

There is an imbalance of the body component composition indicators in patients suffering from psoriasis. The most pronounced abnormalities were found in patients with severe and moderate-to-severe dermatosis. The study of the body component composition can be introduced into clinical practice to form risk groups and as a method of comprehensive examination of patients with psoriasis.
