Methods: 44 (M/F - 18/26) DMARD-na?ve patients (pts) with active EPsA, according to the CASPAR criteria, mean age 37.5±11.3 years, PsA duration 7 [4; 24] months, psoriasis duration 36 [12; 84] months, disease activity index (DAS) 3.78 [3.18; 4.67], DAS28 4.33 [3.67; 4.8] study were included. At the baseline and every other 3 months for total 12 months of therapy all pts underwent standard clinical examination, tender joint count (TJC), swollen joint count (SJC), patient pain VAS, patient/physiciańs global disease activity VAS, enthesitis by Leeds Enthesial Index (LEI)+Plantar Fascia (PF), dactylitis, Psoriasis Area Severity Index (PASI), body surface area (BSA), Health Assessment Questionnaire (HAQ), DAS, DAS28-C-RP, C-RP (mg/l). The dose of MTX s/c was escalated by 5 mg every 2 weeks from 10 mg/wk to appropriate dose 20-25 mg/wk according to the drug intolerance. If pts does not achieve the lower disease activity (LDA), MDA or remission after 3 months of MTX subcutaneous (s/c) mono-therapy, then combination therapy of MTX+Adalimumab (ADA) by standard regime was continued up to one year. At 12 months of therapy the proportion of pts who attained LDA by DAS/DAS28 or remission by DAS<1.6/DAS28-C-RP<2.6 or MDA, ACR20/50/70, PASI75 and dynamics of HAQ, LEI+PF, dactylitis were calculated. Mean±SD, Me [Q25; Q75], %, Friedman (Fr.) ANOVA, U-test, Wilcoxon test were performed. All p<0.05 were considered to indicate statistical significance. Results: At one year of treatment according to T2T strategy significant improvements disease activity and physical health function related to quality of life was seen. By 12 months of therapy remission by DAS and MDA was reached 61.4%/65.9% of pts accordingly. By 12 months of therapy ACR20/50/70 was seen in 88%/77%/59% of pts. In pts with BSA≥3% (n=16) at baseline psoriasis improvements by PASI75 was seen in 88% of pts. In 55% of active EPsA pts MTX (s/c) mono-therapy was an effective treatment. Conclusions: One-year treatment according to T2T strategy significantly improves all PsA clinical domains - Arthritis, dactylitis, enthesitis, skin psoriasis and quality of life despite of type of treatment. It seems that T2T is a useful strategy in EPsA but additional research concerning its implementation in real practice are needed.

The latter is currently indicated as a T-cell-mediated disease that is based on the activation of cellular immunity, followed by the hyperproduction and imbalance of key pro- A nd anti-inflammatory cytokines, such as tumor necrosis factor-α (TNF-α), interleukin-1â (IL-1â), IL-6, IL-12/23, and IL-17. The paper presents the basic principles of diagnosis and clinical manifestations of the disease and notes the importance of screening questionnaires, the use of which allows specialists to diagnose PsA early, by actively identifying articular complaints, the characteristic clinical and radiological signs of damage to the joint, spine, and entheses. It is pointed out that the key target of pharmacotherapy for PsA is to achieve remission or minimal activity of the main clinical manifestations of the disease, to slow down or prevent its radiographic progression, to increase the length and quality of life in patients, and to reduce the risk of comorbidities. The authors characterize the major groups of used drugs: Nonsteroidal anti-inflammatory drugs, conventional and targeted synthetic disease-modifying antirheumatic drugs, and biological drugs (inhibitors of TNF-α, IL-12/23, and IL-17). The key Treat-to-target principles of patient management are considered; it is noted that strict control over disease activity and treatment results provides suppression of all major clinical manifestations of PsA. The paper also shows the basic principles of the creation and further development of the All-Russian Registry of PsA patients, which makes it possible to optimize management decision-making on the provision of high-tech medical care and drugs for this cohort of patients.
