Brief information about modem osteoarthritis treatment with simple analgesics, NSAIDs and chondroprotective drugs is presented. Results of a clinical study of ARTRA in combination with diclofenac (31 pts) comparing with diclofenac only (31 pts) for the treatment of knee osteoarthritis ofll-lll stage are discussed. ARTRA was administered 2 capsules a day during a months and than 1 capsule a day during 5 months. A mean therapeutic dose of diclofenac was given to all pts. ARTRA with diclofenac was more effectively than diclofenac monotherapy improved WOMAC functional index and suppressed pain on visual analog scale and WOMAC. ARTRA was well tolerated.

The aim of the study – Is to evaluate the effectiveness and safety of the use of a functional unloading orthosis with the possibility of varus–valgus correction (FUOVVC) in patients with stage III osteoarthritis of the knee joint.Materials and methods. The study involved 10 patients with stage III osteoarthritis of the knee joint who underwent outpatient treatment at the V.A. Nasonova Federal State Medical University of the Russian Academy of Medical Sciences. All patients used the FUOVVC for 3 months. To evaluate the results, pain intensity was determined using a visual analog scale (VAS) and knee joint function according to the knee injury and osteoarthritis KOOS (Knee injury and Osteoarthritis Outcome Score) questionnaire before using the orthosis, after 1 and 3 months. Additionally, the assessment of VAS was carried out immediately after fixation of the orthosis on the knee joint.Results. The median age of the patients was 63.5 [55.0; 74.0] years, body mass index – 29.9 [27.9; 34.0] kg/m2, pain according to VAS baseline – 40.0 [40.0; 60.0] mm, pain according to VAS 1 hour after the start of the use of The median age of the patients was 63.5 [55.0; 74.0] years, body mass index – 29.9 [27.9; 34.0] kg/m2, pain according to VAS baseline – 40.0 [40.0; 60.0] mm, pain according to VAS 1 hour after the start of the use of FUOVVC – 25.0 [10.0; 30.0] mm, pain according to VAS after 1 month – 10.0 [0.0; 20.0] mm, VAS after 3 months – 10.0 [0.0; 20.0] mm. The median score according to the KOOS questionnaire was initially 41.5 [38.0; 50.0], after 1 month – 61.0 [53.0; 63.0], after 3 months – 63.5 [58.0; 64.0]. None of the patients had any adverse events when wearing the FUOVVC. – 25.0 [10.0; 30.0] mm, pain according to VAS after 1 month – 10.0 [0.0; 20.0] mm, VAS after 3 months – 10.0 [0.0; 20.0] mm. The median score according to the KOOS questionnaire was initially 41.5 [38.0; 50.0], after 1 month – 61.0 [53.0; 63.0], after 3 months – 63.5 [58.0; 64.0].

Rituximab is a chimeric (mouse and human) monoclonal antibody against B-lymphocytes (CD20). This drug is widely used in rheumatology in the treatment of rheumatoid arthritis, Sjogren’s syndrome, some systemic connective tissue diseases and vasculitis, as well as in hematology in lymphoproliferative diseases. Administration of rituximab leads to depletion of B-lymphocytes through various mechanisms, including antibody-dependent and complementdependent cytotoxic effects, as well as the regulation of apoptosis. Considering the mechanism of autoimmune damage in Graves’ disease, an autoimmune thyroid disease accompanied by thyrotoxicosis and endocrine ophthalmopathy (an autoimmune lesion of the accessory apparatus of the eye), the use of rituximab may be effective in these diseases. The review considers the currently available results of studies on the use of various doses of rituximab in these diseases.

One of the main tasks of modern complex therapy of rheumatoid arthritis (RA) is to improve the quality of life of patients. To do this, it is necessary not only to achieve remission or low activity, but also to successfully control the main, most painful, manifestations of the disease. Therefore, when evaluating the results of RA treatment, the dynamics of not only standard indices (DAS28 (Disease Activity Score 28), CDAI (Clinical Disease Activity Index), SDAI (Simplified Disease Activity Index)), but also the so-called “patient reported outcomes” (PRO) – a patient’s global assessment of disease activity (PGA), pain, functional disorders and fatigue.This review examines the effect of one of the main classes of anti–rheumatic drugs - biological disease-modifying antirheumatic drugs (bDMARDs) on the PROs. The results of a series of randomized controlled trials are presented, in which changes in PROs were studied using various tumor necrosis factor α (TNF-α) inhibitors, abatacept T-lymphocyte co-stimulation inhibitor, rituximab CD20 inhibitor and interleukin (IL) 6 inhibitors.The use of bDMARDs in combination with methotrexate (MTX) provides a reduction in PGA and pain by 50-60%, functional disorders according to HAQ (Health Assessment Questionnaire) and fatigue according to FACIT-F (Functional Assessment of Chronic Illness Therapy – Fatigue) – by 15-30%. B DMARDs monotherapy (with the exception of the effect of tocilizumab on HAQ) does not exceed MTX monotherapy in its effect on PROs. Monotherapy with tocilizumab provides more favorable dynamics of PGA and pain than monotherapy with TNF-α inhibitors. An important advantage of IL-6 inhibitors is the rapid achievement of a clinical effect, which is noted already in the first 2 weeks after the first administration of the drug.

The prescribing of biological disease-modifying antirheumatic drugs (bDMARDs) and Janus kinase inhibitors (iJAK) during the COVID-19 pandemic requires a balanced approach and tight monitoring of the patients.The aim of the study was to study the effect of bDMARDs and iJAK inhibitors on the condition of patients with rheumatoid arthritis (RA), taking the patients reported outcomes, as well as the incidence of COVID-19 in these patients.Materials and methods. A telephone survey was conducted of 254 patients with RA (average age – 49.8±13.7 years; 64.4% of patients are positive for rheumatoid factor; women – 83.5%; DAS28 score – 5.4±1.6 points), who in the period from January 2020 to June 2021 were prescribed bDMARDs or iJAK for the first time: 148 (58.3%) – rituximab; 57 (22.4%) – tumor necrosis factor α inhibitors; 20 (7.9%) – iJAK; 17 (6.7%) – interleukin 6 inhibitors; 12 (4.7%) – abatacept.Results. At the time of the survey, 204 (80.3%) patients continued taking prescribed medications. The main reason for the interruption of treatment was administrative problems. Synthetic DMARDs (mainly methotrexate and leflunomide) were received by 68.0%, glucocorticoids – 45.3%, nonsteroidal anti-inflammatory drugs – 44.5% of respondents. Among patients treated with bDMARDs or iJAK, 68.1% noted «the state of symptoms acceptable to the patient», the absence of frequent joint pain – 65.3%, the absence of increased fatigue – 14.3%. The incidence of COVID-19 and hospitalization associated with this disease did not differ in individuals who continued and stopped using bDMARDs or iJAK: 41.2% and 44.6%, 13.7% and 14.0%, respectively (p=0.80884). There were no statistically significant differences in the incidence of COVID-19 and hospitalization associated with this disease in patients taking various bDMARDs or iJAK.Conclusion. Despite the COVID-19 pandemic, rituximab remains one of the most popular bDMARDs. About a third of patients receiving bDMARDs or iJAK are not satisfied with their condition. More than 40% of patients who received these drugs suffered COVID-19; 14.0% required hospitalization.

The prevalence of sarcopenia in different countries of the world has been well studied. However, the criteria of different international professional groups are used to diagnose the disease, which leads to large variability in data on the frequency of sarcopenia in the population. The paper presents the results of studying the frequency of sarcopenia, by using the diagnostic criteria of different working groups. The measures characterizing muscle strength and skeletal muscle function were analyzed; the components that are most important for the diagnosis of sarcopenia were identified in the studied patient group.Objective: to determine the detection rates of sarcopenia among people aged over 65 years in accordance with the guidelines of different international professional groups and to identify the most significant component for its diagnosis.Subjects and methods. The investigation enrolled 230 people older than 65 years (mean age, 74.0±6.5 years) who were followed up in an outpatient setting. Sarcopenia was diagnosed according to the 2010 European Working Group on Sarcopenia in Older People (EWGSOP) criteria. To confirm its diagnosis, the appendicular muscle mass index (AMMI) was calculated using dual-energy X-ray absorptiometry (DXA) on a HOLOGIC QDR Explorer; muscle strength was measured with a Jamar-J00105 handheld dynamometer (Sammons Preston Inc., USA). Muscle function was also examined using the short physical performance battery (SPPB). The frequency of sarcopenia diagnosed by the criteria of the International Working Group on Sarcopenia (IWGS), the Foundation for the National Institutes ofHealth (FNIH), and EWGSOP were comparatively analyzed. Results and discussion. The frequency of sarcopenia in the sample of people aged over 65 years was the same when using the diagnostic EWGSOP and IWGS criteria (30%) and was significantly higher than when applying the FNIN criteria (19.8%). The frequency of sarcopenia increased from 21.4% at the age of 65–74 years to 52.9% at the age of over 85 years according to the EWGSOP and IWGS criteria and from 16.2% to 29.4%, respectively, by the FNIN criteria. Dynamometry showed that the muscle strength was significantly lower in patients with low muscle mass than in those with normal muscle mass (the average mass was 15.1±5.4 and 18.2±5.4 kg, respectively; p

Pathological changes of large joints (knee, hip) in osteoarthritis (OA) are accompanied by the development of muscle weakness, decreased proprioception and imbalance.Objective: assessment of skeletal muscles state in women over 65 years old with OA of large joints and determination of the main factors affecting the risk of sarcopenia.Subjects and methods. In 159 women with OA (mean age 74±6 years), muscle mass was assessed with the appendicular lean mass index (ALM) using dual-energy X-ray absorptiometry (DXA). Muscle strength was measured by hand dynamometer, muscle function was determined by the results of a brief set of physical activity tests (short physical performance battery – SPP). The quality of life was analyzed by the EQ-5D questionnaire, pain assessment was carried out using a visual analog scale (VAS).Results and discussion. Patients with sarcopenia were significantly more likely to have lower rates of ALM index (p

The aim is to carry out language adaptation and validation on the Russian sample of a special SarQoL questionnaire, designed to assess the quality of life of elderly people with sarcopenia. Material and methods. 100 patients over 65 years, mean age 74.0±6.5 years, observed on an outpatient basis were included. 50 from them had sarcopenia and 50 participants were without it. The diagnosis of sarcopenia was based on criteria developed by the European working group on sarcopenia (EWGSOP, 2010). The validation procedure was carried out in accordance with the Protocol. Results and discussion. There was a significant decrease in the overall quality of life according to SarQoL questionnaire in patients with sarcopenia compared with the control group without sarcopenia (50.65±14.23 and 75.10±14.46, respectively; p

Objective: to analyze the dynamics of quality of life (QOL) in patients with prior osteoporotic vertebral compression fracture during an 18-month follow-up study. Subjects and methods. The investigation enrolled 219 patients (mean age, 67.6 years) with vertebral fracture from seven centers of the Russian Federation. QOL was assessed four times using the EQ-5D (EuroQoL-5D) and TTO (Time Trade-Off) questionnaires during an 18-month prospective follow-up study. The work was done within the framework of the International Multicenter Study ICUROS (The International Costs and Utilities Related to Osteoporotic Fractures Study) organized by the International Osteoporosis Foundation (www.icuros.org).Results and discussion. The patients with vertebral compression fracture showed a statistically significant decrease in QOL throughout the follow-up period. Immediately after the fracture, there was a dramatic decrease in the total EQ-5D score, followed by its gradual increase. However, the emerging trend in QOL recovery proved to be unstable, and by the end of the 18th month, it was significantly lower than that before the fracture. On the contrary, the TTO questionnaire showed that QOL drastically decreased immediately after fracture, but at month 4 it reached the level that was before the fracture, and remained stable until the end of the follow-up period.Conclusion. The performed investigation enabled us to obtain data on QOL using the EQ-5D (QOL assessment from the social point of view) and TTO (individual QOL assessment) in the population of residents of the Russian Federation, in men and women aged 50 years and older with osteoporotic vertebral compression fracture.
