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.
Gout is a chronic inflammatory arthropathy, caused by articular and periarticular sodium monourate (MUN) crystals deposition on the background of chronic hyperuricemia. Gout belongs to the group of autoinflammatory diseases characterized by activation of the innate immune system. In some cases, especially in women, with a long course of the disease and absence of adequate therapy, chronic arthritis is detected, which has little difference from that in rheumatoid arthritis (RA). At the same time, until recently, the combination of RA and gout was considered casuistry due to the inhibition of crystal formation by specific factors associated with RA, what is more mechanisms of inflammation development characteristic of these diseases are completely different. However, according to the latest data, the coexistence of these two diseases in one patient is possible, and the therapy of both, gout and RA (in some patients) can be successful when prescribing biological disease modifying antirheumatic drugs, in particular inhibitors of the interleukin 1 receptor (IL1r).The article presents a rare clinical case of chronic tophi gout in an elderly patient who was followed up for a long time with a diagnosis of RA, a significant improvement was achieved on therapy with the IL1r antagonist anakinra.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
