Popis: Achievement of minimal disease activity (MDA) is the main goal of the Treat-to-target (T2T) strategy in early psoriatic arthritis (ePsA). Radiographic progression in patients with ePsA treated according to the T2T strategy has been studied insufficiently. Objective: To study the frequency of achievement of MDA and X-ray progression in patients with early PsA treated according to the T2T strategy 1 year after initiation of treatment. Subjects and methods. Forty patients (22 women) with active ePsA, who met the CASPAR criteria (mean age was 38,4±11,1 years, the median duration of PsA – 7,0 [4,0; 18,0] months, the duration of psoriasis – 38,0 [9,5; 114,0] months, DAS – 3,8 [3,2; 4,7]), were included in the REMARKA study. At the start of the study all patients received subcutaneous methotrexate (MTX) in a dose of 20–25 mg/week. If high or moderate disease activity persisted after 3–6 months, patients (n=21) were transferred to combined therapy with MTX and a biological agent (BA). The remaining 19 patients continued MTX monotherapy. Initially and one year later, the MDA criteria were evaluated (tender joint count ≤1, swollen joint count ≤1, PASI ≤1 or BSA ≤3, pain on visual analog scale (VAS) ≤15 mm, patient global assessment of activity on VAS ≤20 mm, HAQ ≤0,5, tender enthesis count ≤1) and digital radiography of hands and feet was performed. Radiographic progression was assessed by an independent radiologist using the modified method of Sharp/van der Heijde: total score (TS) = erosion score (ES) + joint space narrowing score (JSNS). Results and discussion. At the time of enrollment, 23 patients (57%) with ePsA had erosions. One year later the number of patients with erosions increased to 26 (65%). The TS has significantly increased, although its median has not changed (before treatment – 91.5 [72; 108,5], after one year – 91.5 [73,5; 111,5], p0,05). In 29 out of 40 patients (72,5%), no radiographic progression was detected neither in the ES nor in the JSN; 13 out of 29 (45%) received MTX and 16 (55%) – MTX + BA. In 11 out of 40 (27,5%) patients, negative radiographic changes according to ES (n=10) and JSNS (n=4) were detected, with three patients having progression in both scores. In this group, 6 patients (54,5%) received MTX monotherapy and 5 (45,5%) – MTX + BA. After 1 year, 25 (62,5%) patients achieved MDA. Among patients who did not achieve MDA (n=15) after 1 year, the ES was significantly higher at the beginning of the study compared to those who achieved MDA: median 3 [2; 9] and 0 [0; 3], respectively (p< 0,05). In the group of patients who did not achieve MDA in a year, radiographic progression was more significant. Conclusion. In russian cohort more than half of patients with ePsA had erosions. After one year of follow up 72,5% of patients with ePsA treated according to the T2T strategy showed no radiographic progression, and a quarter of patients (27,5%) had negative radiographic changes, regardless of the type of the therapy. Patients with ePsA, who achieved MDA, had less prominent radiographic progression in a year.
