The use of selective Janus kinase inhibitor upadacitinib in a patient with psoriatic arthritis (clinical observation)

We describe a patient with psoriatic arthritis (PSA) and palmoplantar psoriasis, resistant to standard therapy, who observed a significant decrease in disease activity on the background of upadacitinib at a dose of 15 mg/day. Remission was achieved by the 3rd month of treatment. No adverse phenomena were observed within 6 months of treatment.
