RESUMO
AIM: To study and compare the clinical and imaging characteristics of psoriatic arthritis (PsA) in men and women. MATERIALS AND METHODS: The study included 956 PsA patients observed in the Russian register, 411 (43%) men and 545 (57%) women. The average age of men/women was 46.0±16.50/50.7±17.20 years (p<0.001), the duration of PsA was 9.9±6.4/10.3±7.6 years (p>0.05), the age at the time of PsA establishment was 37.1±12.30/41.8±13.5 years (p<0.001). Rheumatological examination, X-ray of the pelvis, hands, feet were performed, the LEI, plantar fascia tenderness, body surface area (BSA), body mass index (BMI), CRP, HLA-B27 were determined. Patients filled out assessment scales of pain (Pain), disease activity (patient global assessment of disease activity - PGA), questionnaires HAQ-DI. The indices of Disease Activity in PSoriatic Arthritis (DAPSA), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), criteria of minimal disease activity (MDA) were evaluated. RESULTS: The following differences in the course of PsA in men/women were revealed: X-ray sacroiliitis was detected in 175 (42.6%)/153 (28.1%); p<0.001; the presence of erosions of the joints of the hands and feet - 138 (33.6%)/170 (31.2%); p=0.435; LEI≥3 - 34 (11.4%)/78 (20.9%); p=0.001; Pain - at 48.5±22.60/51.5±22.80 mm VAS; p=0.043; PGA - 50.2±23.07/54.0±21.91 mm VAS; p=0.010; moderate and severe functional disorders (HAQ-DI) were more often observed in women (p=0.002 and p<0.001, respectively); the average value of DAPSA is 26.4±16.8/31.9±22.58; p<0.001; average BASDAI value: 2.7±2.83/1.8±2.78; p<0.001; MDA was achieved in 13 (3.2%)/22 (4.1%); p=0.486; BSA>10% - 54 (13.1%)/102 (18.7%); p=0.021; comorbid diseases - 154 (37%)/277 (51%); p<0.001. At the time of inclusion in the register, the proportion of patients receiving biologic disease-modifying anti-rheumatic drugs was higher in the group of men. CONCLUSION: Our data, based on a large cohort study, demonstrate that PsA debuts in women at a later age than in men, the course of the disease is characterized by higher activity of peripheral arthritis, more pronounced functional disorders and a high prevalence of comorbid diseases. This creates a heavier burden of PsA in women and indicates that gender is an important characteristic of the patient that should be used to predict the course, therapeutic response and progression of the disease.

BACKGROUND: Non-pharmacological treatments based on collagen as a dietary supplement are emerging as a new area of interest to support preventive or therapeutic effects in patients with osteoarthritis (OA). AIM: In a multicenter, prospective, double-blind, placebo-controlled, randomized study, to evaluate the effectiveness and safety of the use of the Artneo complex containing undenatured chicken collagen type II in patients with OA of the knee joints. MATERIALS AND METHODS: The study enrolled 212 outpatients from 12 centers in the Russian Federation with knee OA, stages II and III according to the Kellgren-Lawrence classification. The participants included 171 women (80.7%) and 41 men (19.3%), with an average age of 60.2±9.0 years (range: 40 to 75 years). The study population was randomly allocated in equal proportions into two groups using an interactive web response system (IWRS). Group 1 (Artneo) consisted of 106 patients who took one capsule of the drug once daily for 180 days. Group 2 (Placebo) also had 106 patients, with the dosage form and regimen identical to Group 1. During the treatment period, the following outcomes were assessed: WOMAC index, KOOS, pain according to VAS, quality of life using the EQ-5D questionnaire, and the need for NSAIDs. All patients underwent a clinical blood test, general urine analysis, biochemical blood test, and ultrasound examination of the affected knee joint. RESULTS: In a prospective, double-blind, placebo-controlled, randomized study, it was demonstrated that the Artneo combination, containing undenatured chicken collagen type II, has a positive effect on all clinical manifestations of OA: it effectively reduces pain, stiffness, and improves the functional state of joints and quality of life. It has a good safety profile and is superior to placebo in all parameters studied. CONCLUSION: The results of the study confirm the good effectiveness and safety of the Artneo combination in patients with OA of the knee joints.
