Experience of therapy of psoriasis patients with methotrexate in the form of subcutaneous and intramuscularly injections

Psoriasis is one of the most common chronic dermatoses. About 125 million patients with this disease are registered in the world, and the frequency of occurrence in the structure of dermatological diseases is about 40%. Despite the fact that in most cases psoriasis does not pose a threat to life, but, nevertheless, it is the direct cause of the appearance of very serious pathological problems, social maladjustment. Recently, an increasing number of researchers speak of psoriasis not as an isolated skin disease, but as a systemic psoriatic disease with dominant skin manifestations. The systemic nature of the disease is manifested in the frequent involvement in the process of not only the skin, but also other systems and organs, in particular, the musculoskeletal system in the arthropathic form of psoriasis (psoriatic arthritis). The prevalence of psoriatic arthritis in patients with psoriasis ranges from 7 to 47%, and in 15% of patients arthritis develops before skin lesions, with ordinary psoriasis, arthritis occurs in 6-7% of cases, and with already identified psoriatic arthropathy in 73,2%, pustular or exudative psoriasis, as well as psoriatic erythroderma. The article presents the results of the use of methotrexate in the form of subcutaneous injections in clinical practice in the treatment of patients with moderate and severe psoriasis, in comparison with a similar scheme of using intramuscular injections of methotrexate. The course of methotrexate therapy has been shown to be highly effective in the treatment of psoriasis and psoriatic arthritis. The data on higher safety, a more significant positive effect on the quality of life, better tolerability and longer remission of the process achieved in a group of patients receiving subcutaneous injections of methotrexate are presented.
