Combating the consequences of COVID-19, a disease caused by the new coronavirus infection SARS-CoV-2, is a serious and very urgent task facing modern medicine. COVID-19 often has a severe course and is accompanied by multiple organ damage, systemic immune inflammation, coagulopathy, neuroendocrine and metabolic disorders. Even with a relatively favorable course, the consequences of SARS-CoV-2 infection can be degenerative changes in many organs (pulmonary fibrosis, cardiosclerosis), various functional and psychoemotional disorders. As a result, in 10–50% of patients, various unpleasant symptoms persist for a long time after the acute manifestations of COVID-19 subside and the virus is eliminated. This pathology is referred to as “post-COVID syndrome” (PCS). The main elements of PCS are chronic pain, fatigue, and psychoemotional problems. Functional disorders, autoimmune processes, and severe psychological distress after COVID-19 can cause the development and exacerbation of diseases characterized by chronic pain and fatigue, such as fibromyalgia and chronic fatigue syndrome. Therapy and prevention of PCS include correction of functional disorders, pain control, and consistent physical, psychological, and social rehabilitation.

Rheumatoid arthritis (RA) is the most frequent immunoinflammatory (autoimmune) rheumatic disease characterized by chronic erosive arthritis and systemic damage to internal organs. The data obtained in the course of basic research on deciphering the mechanisms of action of methotrexate (MT) and the materials of numerous randomized placebocontrolled trials, observational studies and national registries have strengthened the position of MT as the “gold standard” of RA pharmacotherapy and a key component of the “Treatment to Target” strategy. This was the basis for the development of new recommendations of the Association of Rheumatologists of Russia (ARR) concerning the use of MT in RA, according to which MT is considered as the drug of “choice” for induction and maintenance of remission in patients with early and advanced RA, including those who need combination therapy of MT with glucocorticoids, standard Disease-Modifying Antirheumatic Drugs (DMARDs), biologics and targeted synthetic DMARDs. Special attention is paid to the safety of MT therapy and the impact of MT on comorbid pathology associated with cardiovascular complications and interstitial lung disease. Implementation of the ARR recommendations into clinical practice will reduce the risk of disability and improve life prognosis in patients with RA.

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.

Background. The combined use of intramuscular injection glycosaminoglycan peptide complex (GPC) and oral diacerein can increase the effectiveness of treatment of osteoarthritis (OA). Aim. Compare the effectiveness of combination GPC + diacerein and GPC monotherapy in the treatment of OA in clinical practice. Materials and methods. A retrospective evaluation of the results of a 12-week multicenter observational non-interventional study of the effectiveness of GPC (Rumalon, a course of intramuscular injections 3 times a week, №25) in patients with moderate/severe OA (n=2955) requiring regular administration of nonsteroidal anti-inflammatory drugs (NSAIDs). The analysis identified a group of patients (n=414) who received GPC in combination with diacerein 100 mg/day (Diaflex Rompharm). The therapeutic effect was compared in the groups of GPC monotherapy (n=2541) and the combination of GPC with diacerein. These groups did not differ in average age (61.411.8 and 61.911.3 years), both were dominated by women (76.3 and 70.3%), there was approximately equal intensity of pain during movement and impaired joint function: 6.11.8/6.01.6 and 4.92.1/5.11.8 (according to the numerical rating scale 010). The dynamics of pain intensity, the need for NSAIDs, and the frequency of adverse events (AE) were compared 12 weeks after the start of treatment. Results and discussion. In the majority of patients with OA both on the background of GPC monotherapy and combined use of GPC and diacerein, there was a significant improvement. The number of patients with pain reduction 50% was 54.3 and 62.8% (p0.001), NSAID administration was completely stopped in 66.7 and 77.5% (p0.001), respectively. The effectiveness of the combination of GPC and diacerein was significantly higher than that of GPC monotherapy in OA of the knee joint, hip joint, and generalized OA. AE from the gastrointestinal tract was observed in 7.8 and 8.9%, arterial hypertension in 6.3 and 4.6%, allergic reactions in 0.3 and 0.5% of patients (not significant). Conclusion. The application of the code of civil procedure is an effective treatment for OA. The combination of GPC and diacerein provides a more significant improvement than GPC monotherapy. GPC and diacerein (including in combination) are well tolerated and rarely cause AE.

Aim: Evaluate the efficacy and safety ® (olokizumab) in patients with rheumatoid arthritis (RA) in real‐world clinical practice, with a targeted assessment of patient report outcomes (PRO) and central sensitization.Methods: An open‐label observational non‐interventional study was conducted, enrolling 183 patients with moderate and severe RA activity. All patients received OKZ 64 mg SC as injections every 4 weeks (Q4W) with methotrexate. The patients' follow‐up period was 24 weeks or less. RA activity (DAS28‐CRP), pain severity (NRS), patient global assessment (PGA, NRS), functional impairment (NRS), fatigue (FACIT‐F), central sensitization (central sensitization inventory, CSI), and symptoms of neuropathic pain (PainDETECT) were evaluated.Results: The study cohort was comprised of 144 patients. And 39 patients were lost to follow‐up, refused OKZ treatment, or were not dosed with OKZ for administrative reasons. In 6 months, DAS28‐CRP decreased to 3.3 ± 0.9 (p < .001) and statistically significant reductions in pain intensity, PGA, functional impairment, and fatigue were achieved. Pain intensity decreased as early as 2 days after the first OKZ administration (p < .05). The number of patients with CSI >40 in 24 weeks decreased from 71.0% to 21.0% (p < .001), with PainDETECT >18 – from 21.5% to 13.2%. NSAIDs use decreased from 70.8% to 33.8% (р < .001), steroids – from 54.2% to 32.6%. AEs were reported in 14.2% patients, serious events were observed in three patients.Conclusion: OKZ is effective in reducing RA activity and controlling chronic pain related to dysfunction of the nociceptive system.
