RESUMEN

Biological agents are widely used for the management of systemic rheumatic diseases (SRDs) and their therapeutic implications have been expanded beyond inflammatory arthropathies to more complicated autoimmune disorders, such as systemic lupus erythematosus, vasculitis, and systemic sclerosis. The aim of this study was to investigate treatment satisfaction and overall experience of SRDs' patients receiving biologics as well as to explore patient's perspectives on the quality of services provided by rheumatology departments and to determine factors related to the level of satisfaction. We performed a synchronous correlation study. Patients with SRDs answered an anonymous questionnaire assessing their satisfaction and how treatment with biologics has affected their quality of life and functionality. Sample consisted by 244 patients (65.2% women), with mean age of 50.4 years, and the most common diagnosis was rheumatoid arthritis (37.3%). Sixty one percent of patients received intravenous therapy and 39% subcutaneously. Overall, 80.5% of the patients reported a positive/very positive effect of their treatment on their life. The average total patient satisfaction from the unit was 79.8%. The presence of mental disease was significantly associated with less positive impact of the treatment on patients' life, worse quality of life, and greater pain. In conclusion, patients with a broad spectrum of SRDs were generally satisfied and treatment with biologic regimens appeared to have a positive impact on several aspects of their life. The majority of patients were at least satisfied with all the characteristics of the unit staff and better quality of life was associated with greater satisfaction about the Unit and more positive affect of the treatment in patients' life.

RESUMEN

PURPOSE OF THE STUDY: Reduced Bone Mineral Density (BMD) is a prevalent comorbidity in Juvenile Idiopathic Arthritis (JIA). Enthesitis and other tendon abnormalities, such as tenosynovitis, tendinitis and tendon ruptures are, also, common extra-articular manifestations of the disease. The aim of the present study was to investigate the effect of tocilizumab, an antibody that binds the Interleukin-6 (IL-6) Receptor, on inflammation-related bone loss and tendon inflammation in an animal model of JIA. MATERIALS AND METHODS: The Collagen-Induced Arthritis (CIA) model was induced in male rats followed by intraperitoneal administration of tocilizumab for 8 weeks. Methotrexate, the most widely used Disease-Modifying Antirheumatic Drug in the management of JIA, was, also, administered, either as a monotherapy or as an add-on therapy to tocilizumab. BMD was evaluated with Micro-Computed Tomography (Micro-CT) and histopathological examination. Tendon damage was, also, assessed histologically. Finally, two pro-inflammatory cytokines, Tumor Necrosis Factor-alpha (TNF-a) and Interleukin-23 (IL-23) were quantified in tendon tissues by ELISA analysis. RESULTS: Tocilizumab-treated animals exhibited a significantly improved trabecular microarchitecture on micro-CT analysis and histological examination. Tendon morphology was also improved. Anti-IL-6 treatment led to a significant decrease in TNF-a and IL-23 expression in tendon tissue. CONCLUSIONS: The results of the present study provide evidence that tocilizumab reduces inflammation-related bone loss and suppresses tendon inflammation in a juvenile CIA rat model. These findings offer perspectives for the management of osteoporosis and enthesitis in JIA.

RESUMEN

Reduced Bone Mineral Density (BMD) and tendon abnormalities, such as tenosynovitis and enthesitis, are prevalent comorbidities in patients with rheumatoid arthritis (RA). The aim of the present study was to investigate the effect of chronic treatment with infliximab on BMD and tendon inflammation in an animal model of inflammatory arthritis. Collagen-Induced Arthritis (CIA) was induced in rats, followed by long-term intraperitoneal administration of infliximab. Two additional groups of animals received methotrexate either as a monotherapy or as a co-treatment to infliximab. BMD was evaluated by Micro-Computed Tomography (Micro-CT) and bone histological examination. Tendon inflammation was assessed histologically and by quantitative ELISA analysis of pro-inflammatory cytokines in tendon tissues. Both methotrexate and infliximab treatment alleviated joint inflammation and reduced paw edema. Infliximab-treated animals exhibited an improved trabecular microarchitecture on micro-CT and histological analysis compared to both non-treated and methotrexate-treated animals. Infliximab almost reversed the pathological changes in tendons induced by CIA. Finally, we observed statistically significant declines in tendon TNF-a and IL-23 levels after infliximab treatment. Our study provides evidence that infliximab prevents arthritis-related osteoporosis and suppresses tendon inflammation in an animal model of inflammatory arthritis, in addition to controlling disease activity. These findings offer perspectives for the management of osteoporosis and enthesitis in RA.

RESUMEN

BACKGROUND: Binaural Beats (BB) consist of two artificial acoustic stimuli with different frequency, presented simultaneously but independently to each ear. The human brain perceives and synchronizes to this frequency difference (entrainment). Aim of this study was to test the hypothesis that brain entrainment to a lower function rhythm, with BB application, can decrease pain perception and analgesic medication use, in chronic pain patients. METHODS: In a double blind, randomized, cross-over trial, BB at 5Hz (theta rhythm) were applied for 30 minutes, under simultaneous electroencephalogram recordings, followed by liberal, on demand use by chronic pain patients for a week, compared to sham stimulation (SS). Pain as the main outcome (numeric scale, NRS), stress (STAI) and medication usage (defined daily doses, DDD) were assessed at baseline, 30 minutes and week's end. RESULTS: Perceived pain (NRS) was significantly reduced in BB intervention (5.6±2.3 to 3.4±2.6, p<0.001), compared to SS (5.2±2.1 to 4.8±2.3, p=0.78), during the first 30-minute phase, as well as at the week's end (to 3.9±2.5 compared to 5.5±2.6 respectively, p<0.001). The mean EEG theta power at 5Hz was significantly increased only during BB application. Stress was significantly reduced at 30 minutes in both interventions but remained reduced only in the BB group at the week's end. Analgesic medication consumption (DDD, g) during the week was significantly less in the BB intervention (3.9±3.7 vs. 4.6±4.1, p<0.05), while reporting equal to SS mean levels of pain. CONCLUSIONS: Acoustic BB reduced pain intensity, stress and analgesic use, compared to SS, in chronic pain patients. SIGNIFICANCE: This study provides evidence that theta rhythm binaural beats can alleviate pain intensity, both after a brief 30 minute and a longer one week on-demand intervention. The subsequent significant reduction in analgesic medication consumption in chronic pain patients' daily living could offer a valuable tool, augmenting the effect of existing pain therapies.

RESUMEN

BACKGROUND: Repetitive Transcranial Magnetic Stimulation (rTMS) is a non-invasive brain stimulation technique that is being actively explored as a potential therapeutic modality in various neuropsychiatric disorders, such as depression, neuropathic pain, epilepsy, multiple sclerosis, and neurodegenerative disorders, including the Parkinson's and Alzheimer's disease. The Food and Drug Administration (FDA) approved rTMS for the treatment of major depression, migraine-associated headaches, and Obsessive Compulsive Disorder (OCD). The fact that a significant proportion of patients suffering from these disorders fail to respond to current pharmacological interventions indicates the need for alternative therapies like rTMS. OBJECTIVE: The objective was to find and summarize all studies combining the use of rTMS and pharmacological interference in vitro, in order to facilitate future studies. METHODS: The results of studies combining the use of rTMS with pharmacological interference in vitro were focused on. The PubMed database was searched using the terms "rTMS", "repetitive", "transcranial", "magnetic", "stimulation", "in vitro", "in vivo", "cell cultures" untilMarch 2019 and 7 eligible studies were found. RESULTS: Overall results show a synergistic effect of rTMS and pharmacotherapy in vitro with additive effectiveness, better prognosis, and superior potential management. CONCLUSION: The limited amount of knowledge denotes the need for additional in vitro studies on the combination of rTMS and pharmacotherapy, which could be extended to in vivo studies and ultimately help design clinical trials so as to improve the therapeutic management of patients with a wide array of neuropsychiatric disorders.

RESUMEN

CIA is a well-studied animal model of autoimmune arthritis. It resembles rheumatoid arthritis as far as histopathological changes and molecular pathogenesis are concerned. CIA is induced by immunization with collagen type II in susceptible strains. The purpose of this review is to assess the use of CIA animal model on bone metabolism and the potential therapeutic agents that could reverse this effect. A database search from their inception to 2019 was conducted to identify experimental animal studies pertinent to CIA model and bone examination. Studies including ovariectomy or without a direct comparison between control and CIA groups were excluded. Forty-eight articles were considered suitable for inclusion. Imaging techniques, biomechanical analysis, histopathological studies, and molecular biology techniques were employed. A decrease in bone mineral density in CII arthritic animals was established. Bone loss was either periarticular, generalized or both. Although trabecular bone loss was clear, the effect on cortical bone is yet to be determined. The proposed mechanism is an imbalance between bone formation and resorption as a result of osteoclast activation. The signal pathways implicated appear to be the RANKL/RANK/OPG and the Wnt pathway. Many therapeutic targets were investigated with promising results.

RESUMEN

BACKGROUND: Evidence suggests that selenium (Se) supplementation could be useful as an adjunctive therapy to levothyroxine (LT4) in the treatment of Hashimoto's thyroiditis (HT). To summarize evidence regarding its effect on thyroid autoantibodies' titers, demands in LT4 replacement therapy, ultrasonographic thyroid morphology, and mood in patients with HT under LT4 treatment, a systematic review and meta-analysis of relevant literature were performed. METHODS: Systematic review of prospective studies involving patients with HT under LT4 treatment and meta-analysis of studies on randomized, placebo-controlled, blinded trials were performed. RESULTS: Patients with HT assigned to Se supplementation for 3 months demonstrated significantly lower thyroid peroxidase autoantibodies (TPOab) titers (four studies, random effects weighted mean difference: −271.09, 95% confidence interval: −421.98 to −120.19, p< 10⁻4) and a significantly higher chance of reporting an improvement in well-being and/or mood (three studies, random effects risk ratio: 2.79, 95% confidence interval: 1.21-6.47, p= 0.016) when compared with controls. Demands in LT4 replacement therapy and ultrasonographic thyroid morphology were found either unaltered or underreported. CONCLUSIONS: On the basis of the best available evidence, Se supplementation is associated with a significant decrease in TPOab titers at 3 months and with improvement in mood and/or general well-being. Evidence suggests a different pattern of response to Se supplementation in HT relative to baseline TPOab titers, and this, if confirmed, could be used to identify which patients would benefit most from treatment. An improvement in thyroid function and morphology should be demonstrated before Se routine supplementation can be recommended in the treatment of HT.
