    Objective To evaluate the responsiveness in terms of correlation of the Hospital Universitario La Princesa Index (HUPI) comparatively to the traditional composite indices used to assess disease activity in rheumatoid arthritis (RA), and to compare the performance of HUPI-based response criteria with that of the EULAR response criteria. Methods Secondary data analysis from the following studies: ACT-RAY (clinical trial), PROAR (early RA cohort) and EMECAR (pre-biologic era long term RA cohort). Responsiveness was evaluated by: 1) comparing change from baseline (Delta) of HUPI with Delta in other scores by calculating correlation coefficients; 2) calculating standardised effect sizes. The accuracy of response by HUPI and by EULAR criteria was analyzed using linear regressions in which the dependent variable was change in global assessment by physician (Delta GDA-Phy). Results Delta HUPI correlation with change in all other indices ranged from 0.387 to 0.791); HUPI's standardized effect size was larger than those from the other indices in each database used. In ACT-RAY, depending on visit, between 65 and 80% of patients were equally classified by HUPI and EULAR response criteria. However, HUPI criteria were slightly more stringent, with higher percentage of patients classified as non-responder, especially at early visits. HUPI response criteria showed a slightly higher accuracy than EULAR response criteria when using Delta GDA-Phy as gold standard. Conclusion HUPI shows good responsiveness in terms of correlation in each studied scenario (clinical trial, early RA cohort, and established RA cohort). Response criteria by HUPI seem more stringent than EULAR''s

    Optimization of joint syndrome treatment methods, including those based on the intra- and periarticular drug administration and invasive diagnostic techniques, remains high on the agenda of modern clinical rheumatology. The implementation and quite widely spread use of ultrasonographic visualization has been an impetus to the development of this type of treatment for joint diseases. Without any doubt, the quality of intraarticular injection performance mainly depends on the professional level of the specialist and his/hers procedural skills. However, here comes a predictable question: are these conditions sufficient to enable maximal precision, safety, and efficacy of intraarticular interventions? From this perspective, it is interesting to study the possibilities to improve the results of local treatments for the joint syndrome by means of the ultrasound navigation technique. Based on data presented in the literature review, we compared a β€œblind” invasive treatment method to the ultrasound navigation-guided intra- and periarticular interventions in patients with skeletomuscular and connective tissue disorders. The authors of the studies published point to higher safety, efficacy, procedure precision, and diagnostic quality of the information obtained by the ultrasound navigation. Its important advantages include wider possibilities and availability of this method in outpatient settings, due to its rather low costs and patients' safety. The information from the current literature review reflects an initial stage of studies on the evaluation of the role, significance, determination of potential of the ultrasound navigation to enhance the quality of diagnosis and invasive treatment in patients with joint syndromes of various origins and to minimize adverse effects.Одной ΠΈΠ· Π°ΠΊΡ‚ΡƒΠ°Π»ΡŒΠ½Ρ‹Ρ… Π·Π°Π΄Π°Ρ‡ соврСмСнной клиничСской Ρ€Π΅Π²ΠΌΠ°Ρ‚ΠΎΠ»ΠΎΠ³ΠΈΠΈ ΠΏΠΎ-ΠΏΡ€Π΅ΠΆΠ½Π΅ΠΌΡƒ остаСтся оптимизация ΠΌΠ΅Ρ‚ΠΎΠ΄ΠΎΠ² Ρ‚Π΅Ρ€Π°ΠΏΠΈΠΈ суставного синдрома, Π²Β  Ρ‚ΠΎΠΌ числС Π±Π°Π·ΠΈΡ€ΡƒΡŽΡ‰ΠΈΡ…ΡΡ Π½Π° использовании внутрисуставного ΠΈ пСриартикулярного ввСдСния лСкарствСнных ΠΏΡ€Π΅ΠΏΠ°Ρ€Π°Ρ‚ΠΎΠ², Π²Ρ‹ΠΏΠΎΠ»Π½Π΅Π½ΠΈΠΈ диагностичСских ΠΈΠ½Π²Π°Π·ΠΈΠ²Π½Ρ‹Ρ… манипуляций.

    EVALUATION OF EFFECTIVENESS OF INFLUENCE OF THE SUBCUTANEOUS FORM OFMETHOTREXATUM TO THE LEVEL OF PRO-INFLAMMATORY CYTOKINEMIA AND THE MORPHOFUNCTIONAL STATE OF VASCULAR WALL IN PATIENTS WITH RHEUMATOID ARTHRITIS

    Objective: To assess the effect of the subcutaneous form of methotrexatum (metoject) on the level of pro-inflammatory cytokinemia and the morphofunctional characteristics of the vascular wall in patients with rheumatoid arthritis. Methods: The level of pro-inflammatory cytokinemia and the morphofunctional characteristics of carotid arteries were studied in 94 patients with rheumatoid arthritis (RA) positive for RF-IgM and/or anti-citrullinated protein antibody (ACPA). Results: It has been established that in patients with RA as a result of an increase in the serum concentration of pro-inflammatory cytokines (TNF-Ξ±, IL-1Ξ², IL-6) the subclinical lesion of the major arteries, manifested by an increase in the thickness of the intima-media complex (IMC) and the stiffness index of the common carotid artery (CCA) was observed, the magnitude of which was correlated with the duration of RA, the activity index of DAS28, the level of RF and the concentration of ACPA. The use of metoject in RA patients led to a statistically significant decrease in the DAS28 index, a decrease in pro-inflammatory cytokinemia with attainment of control values in the early stages of the disease, a decrease in the thickness of IMC of the CCA, and local (carotid) rigidity of the vascular bed, which is more pronounced with RA duration less than 2 years. It was demonstrated that metoject therapy along with high anti-inflammatory activity, possesses a vasoprotective effect, which is characterized by a decrease in remodeling signs of CCA. Conclusion: The results of the study confirm not only the high clinical efficiency and good tolerancy of the subcutaneous form of metoject, but also show that it possesses a high anti-inflammatory activity, which provides a vasoprotective effect on large vessels of the elastic type (aorta and common carotid arteries)

    The purpose of the study was to compare the phagocytic activity of macrophages of monocytic origin both without activation and under the influence of factors of the M1 and M2 phenotype. Material and methods. Peripheral blood monocytes and Kupper liver cells of male Wistar rats were obtained by gradient centrifugation. The Kupffer cells and rat monocytes were transferred to RPMI growth medium. To activate in the direction of the M1-phenotype, LPS and IFN-Ξ³ were introduced into the medium. To activate the M2 phenotype, IL 4, IL10, and IL 13 were added to the medium. The obtained macrophage cultures were stained with antibodies to CD68. To study the phagocytic activity of macrophages, the cells were placed on plates for intravital microscopy and latex beads were added to the culture medium. Results. The macrophage cultures of monocytic origin and Kupffer cells expressed CD68 at a high level, the addition of activation factors did not change the expression of the marker. 1 hour after the addition of latex particles to the culture medium, unactivated monocytic macrophages statistically significantly absorbed particles more than Kupffer cells. Activation by factors of the M1 and M2 phenotype led to an increase in the phagocytic activity of both macrophages of monocytic origin and Kupffer cells. The most activating effect on phagocytic activity was provided by induction factors of the M1 phenotype. Conclusions. For macrophages of monocytic origin and Kupffer cells, a different dynamics of phagocytic activity is characteristic. Monocytic macrophages initially have a more pronounced absorption capacity, which gradually increases during the experiment. For Kupffer cells, a sharp fluctuation of phagocytic activity is characteristic: rapid growth and rapid saturation.ЦСль исслСдования - ΡΡ€Π°Π²Π½ΠΈΡ‚ΡŒ Ρ„Π°Π³ΠΎΡ†ΠΈΡ‚Π°Ρ€Π½ΡƒΡŽ ΡΠΏΠΎΡΠΎΠ±Π½ΠΎΡΡ‚ΡŒ ΠΌΠ°ΠΊΡ€ΠΎΡ„Π°Π³ΠΎΠ² ΠΌΠΎΠ½ΠΎΡ†ΠΈΡ‚Π°Ρ€Π½ΠΎΠ³ΠΎ происхоТдСния ΠΊΠ°ΠΊ Π±Π΅Π· Π°ΠΊΡ‚ΠΈΠ²Π°Ρ†ΠΈΠΈ, Ρ‚Π°ΠΊ ΠΈ Π² условиях воздСйствия Ρ„Π°ΠΊΡ‚ΠΎΡ€ΠΎΠ² М1- ΠΈ М2-Ρ„Π΅Π½ΠΎΡ‚ΠΈΠΏΠ°.
