BackgroundPsoriatic arthritis (PsA) is a complex immune-mediated disease in which a third of patients with psoriasis (PsO) have a inflammatory lesion of both the musculoskeletal system (peripheral joints and axial structures) and extra-articular manifestations (dactylitis, enthesitis, nail PsO, uveitis and inflammatory bowel disease).AimTo assess the burden of PsA progression in real practice according to the Russian register of PsA patients.Materials And MethodsSeven hundred thirty seven M/F=350 (47.5%)/387 (52.5%) patients with PsA from the Russian register of PsA patients were included. Mean age 47.412.7 yrs., duration of PsO 200.6158.9 mo., PsA 79.681.9 mo. All patients were divided into 2 groups by PsA duration: 1st gr 36 mo 288 (39.1%) and 2nd gr 36 mo 449 (60.9%). All patients underwent standard clinical examination of PsA activity. Tender (68) and swelling (66) joint count (TJC, SJC), DAPSA, LEI, tenderness of the plantar fascia, PsO BSA (%), PASI, HAQ-DI, PsAID-12, BMI (kg/m2), ESR (mm/h), CRP (mg/l) and comorbidities by ICD-10 were evaluated. Parametric and non-parametric methods of statistical analysis were used. All p0.05 were considered to indicate statistical significance.ResultsIn patients with PsA duration 36 mo we found significant prevalence of erosions by X-Ray, axial PsA, BMI30 kg/m2, HAQ-DI1, PsAID-124, arterial hypertension, metabolic syndrome and overall comorbidity (p0.05). There were no significant differences between groups in PsO severity by BSA3%, PASI1, LEI1, TJC, SJC, dactylitis, ESR30 mm/h, CRP10 mg/l, DAPSA, diabetes mellitus, hyperlipidemia, coronary heart disease and liver damage (p0.05). Сonclusion. Long-standing stage PsA is associated with erosions, axial PsA, worst health related quality of life, functional disability and increased cardio-metabolic disorders and overall comorbidity. Our results support the idea to start bDMARDs at early stage of PsA, it can improve better outcomes.
