Similarities and differences between non-radiographic and radiographic axial spondyloarthritis: The patient perspective from the Spanish atlas.

AIM: Although non-radiographic axial spondyloarthritis (EspAax-nr) is well understood within health institutions, being considered along with radiographic EspAax (EspAax-r) as part of the same disease spectrum, patient understanding is unknown. The aim is to describe the patient's knowledge of the EspAax-nr entity. METHODS: Atlas 2017, promoted by the Spanish Federation of Spondylarthritis Associations (CEADE), aims to comprehensively understand the reality of EspAax patients from a holistic approach. A cross-sectional on-line survey of unselected patients with self-reported EspAax diagnosis from Spain was conducted. Participants were asked to report their diagnosis. Socio-demographic, disease characteristics and patient-reported outcomes (PROs) were compared between those patients self-reporting as EspAax-nr and EspAax-r. RESULTS: 634 EspAax patients participated. Mean age 45.7±10.9 years, 50.9% female and 36.1% university-educated. 35 (5.2%) self-reported as EspAax-nr. Compared to EspAax-r patients, those with EspAax-nr were more frequently women (48.6% vs 91.4%, p<0.001), had longer diagnostic delay (10.1±8.9 vs 8.5±7.6 years), higher psychological distress (GHQ-12: 7.5±4.9 vs 5.6±4.4) and similar degree of disease activity (BASDAI: 5.7±2.1 vs 5.7±2.0), and unemployment rates (20.0% vs 21.6%). 20.0% of EspAax-nr received biologics vs 36.9% of EspAax-r, p=0.043. Visits to the rheumatologist in the past year were similar in both groups (3.8±4.5 vs 3.2±3.8), while GP visits were much higher within EspAax-nr (8.0±10.7 vs 4.9±13.3 p=0.003). CONCLUSION: For the first time, EspAax-nr characteristics and PROs have been analyzed from the patient's perspective. Both groups reported similar trends with the exception of EspAax-nr being more frequently women, younger, having longer diagnostic delay and lower use of biologic therapy.

Effects of Biological Therapies on Molecular Features of Rheumatoid Arthritis.

Rheumatoid arthritis (RA) is an autoimmune and chronic inflammatory disease primarily affecting the joints, and closely related to specific autoantibodies that mostly target modified self-epitopes. Relevant findings in the field of RA pathogenesis have been described. In particular, new insights come from studies on synovial fibroblasts and cells belonging to the innate and adaptive immune system, which documented the aberrant production of inflammatory mediators, oxidative stress and NETosis, along with relevant alterations of the genome and on the regulatory epigenetic mechanisms. In recent years, the advances in the understanding of RA pathogenesis by identifying key cells and cytokines allowed the development of new targeted disease-modifying antirheumatic drugs (DMARDs). These drugs considerably improved treatment outcomes for the majority of patients. Moreover, numerous studies demonstrated that the pharmacological therapy with biologic DMARDs (bDMARDs) promotes, in parallel to their clinical efficacy, significant improvement in all these altered molecular mechanisms. Thus, continuous updating of the knowledge of molecular processes associated with the pathogenesis of RA, and on the specific effects of bDMARDs in the correction of their dysregulation, are essential in the early and correct approach to the treatment of this complex autoimmune disorder. The present review details basic mechanisms related to the physiopathology of RA, along with the core mechanisms of response to bDMARDs.

Impaired microRNA processing in neutrophils from rheumatoid arthritis patients confers their pathogenic profile. Modulation by biological therapies.

The aim of this study was to investigate the microRNA (miRNA) expression pattern in neutrophils from rheumatoid arthritis (RA) patients and its contribution to their pathogenic profile and to analyze the effect of specific autoantibodies or inflammatory components in the regulation of miRNA in RA neutrophils and its modulation by biological therapies. Neutrophils were isolated from paired peripheral blood (PB) and synovial fluid samples of 40 patients with RA and from PB of 40 healthy donors. A miRNA array was performed using nCounter technology. Neutrophils from healthy donors were treated in vitrowith antibodies to citrullinated protein antigens isolated from RA patients and tumor necrosis factor-a (TNF-a) or interleukin-6. A number of cytokines and chemokines were analyzed. In vitro treatments of RA-neutrophils with tocilizumab or infliximab were carried out. Transfections with pre-miRNA and DICER downregulation experiments were further performed. RA-neutrophils showed a global downregulation of miRNA and genes involved in their biogenesis, alongside with an upregulation of various potential mRNA targets related to migration and inflammation. Decreased levels of miRNA and DICER correlated with autoimmunity, inflammation and disease activity. Citrullinated protein antigens and TNF-a decreased the expression of numerous miRNA and their biogenesis-related genes, increasing their potential mRNA targets. Infliximab reversed those effects. Transfections with pre-miRNA-223, -126 and -148a specifically modulated genes regulating inflammation, survival and migration whereas DICER depletion influenced the inflammatory profile of neutrophils. Taken together RA-neutrophils exhibited a global low abundance of miRNA induced by autoantibodies and inflammatory markers, which potentially contributed to their pathogenic activation. miRNA biogenesis was significantly impaired in RAneutrophils and further associated with a greater downregulation of miRNA mainly related to migration and inflammation in synovial fluid neutrophils. Finally, anti-TNF-a and anti-interleukin-6 receptor treatments can modulate miRNA levels in the neutrophils, minimizing their inflammatory profile.

Ubiquinol Effects on Antiphospholipid Syndrome Prothrombotic Profile: A Randomized, Placebo-Controlled Trial.

OBJECTIVE: Antiphospholipid syndrome (APS) leukocytes exhibit an oxidative perturbation, directly linked to alterations in mitochondrial dynamics and metabolism. This disturbance is related to the patients' prothrombotic status and can be prevented by in vitro treatment with coenzyme Q10. Our aim was to investigate short-term effects of in vivo ubiquinol (reduced coenzyme Q10 [Qred]) supplementation on markers related to inflammation and thrombosis in APS through a prospective, randomized, crossover, placebo-controlled trial. APPROACH AND RESULTS: Thirty-six patients with APS were randomized to receive Qred (200 mg/d) or placebo for 1 month. Thirty-three patients with APS completed the intervention, which increased plasma coenzyme Q10. Qred improved endothelial function and decreased monocyte expression of prothrombotic and proinflammatory mediators, inhibited phosphorylation of thrombosis-related protein kinases, and decreased peroxides and percentage of monocytes with depolarized mitochondria; mitochondrial size was increased, and mitochondrial biogenesis-related genes were upregulated. Qred ameliorated extruded neutrophil extracellular traps in neutrophils and downregulated peroxides, intracellular elastase, and myeloperoxidase. Nanostring microRNA profiling revealed 20 microRNAs reduced in APS monocytes, and 16 of them, with a preponderance of cardiovascular disease-related target mRNAs, were upregulated. Monocytes gene profiling showed differential expression of 29 atherosclerosis-related genes, 23 of them changed by Qred. Interaction networks of genes and microRNAs were identified. Correlation studies demonstrated co-ordinated effects of Qred on thrombosis and endothelial function-associated molecules. CONCLUSIONS: Our results highlight the potential of Qred to modulate the overexpression of inflammatory and thrombotic risk markers in APS. Because of the absence of clinically significant side effects and its potential therapeutic benefits, Qred might act as safe adjunct to standard therapies in APS.

Mitochondrial dysfunction in antiphospholipid syndrome: implications in the pathogenesis of the disease and effects of coenzyme Q(10) treatment.

The exact mechanisms underlying the role of oxidative stress in the pathogenesis and the prothrombotic or proinflammatory status of antiphospholipid syndrome (APS) remain unknown. Here, we investigate the role of oxidative stress and mitochondrial dysfunction in the proatherothrombotic status of APS patients induced by IgG-antiphospholipid antibodies and the beneficial effects of supplementing cells with coenzyme Q(10) (CoQ(10)). A significant increase in relevant prothrombotic and inflammatory parameters in 43 APS patients was found compared with 38 healthy donors. Increased peroxide production, nuclear abundance of Nrf2, antioxidant enzymatic activity, decreased intracellular glutathione, and altered mitochondrial membrane potential were found in monocytes and neutrophils from APS patients. Accelerated atherosclerosis in APS patients was found associated with their inflammatory or oxidative status. CoQ(10) preincubation of healthy monocytes before IgG-antiphospholipid antibody treatment decreased oxidative stress, the percentage of cells with altered mitochondrial membrane potential, and the induced expression of tissue factor, VEGF, and Flt1. In addition, CoQ(10) significantly improved the ultrastructural preservation of mitochondria and prevented IgG-APS-induced fission mediated by Drp-1 and Fis-1 proteins. In conclusion, the oxidative perturbation in APS patient leukocytes, which is directly related to an inflammatory and pro-atherothrombotic status, relies on alterations in mitochondrial dynamics and metabolism that may be prevented, reverted, or both by treatment with CoQ(10).

Indicación de terapia anti-TNF alfa en pacientes con espondilitis anquilosante en España / Indication for anti-TNF-alpha treatment in patients with ankylosing spondylitis in Spain

Objetivos: Conocer el perfil que el reumatólogo español percibe del paciente con espondilitis anquilosante (EA) que es candidato a terapia biológica. Determinar qué proporción de pacientes con EA son candidatos a recibir este tratamiento y saber hasta qué punto esta decisión concuerda con las recomendaciones del grupo de trabajo Assessment in Ankylosing Spondylitis (ASAS working group) y de la Sociedad Española de Reumatología (SER) sobre el uso de terapias anti-TNF (factor de necrosis tumoral). Método: Reumatólogos de 19 centros hospitalarios españoles, expertos en tratar a pacientes con EA y en el uso de fármacos anti-TNFpero que desconocían las recomendaciones del grupo ASAS y de la SER (inéditas hasta este trabajo), tuvieron que evaluar a 10 pacientes con EA, de forma consecutiva, y decidir si cada uno de ellos comenzaría un tratamiento con fármacos antiTNF, según sus propios criterios. Resultados: De 185 pacientes incluidos en el estudio, al 37,8% se clasificó como candidatos a anti-TNF. Comparados con el resto del grupo, los candidatos tenían mayor grado de actividad inflamatoria, concentraciones más elevadas de velocidad de sedimentación globular (VSG) y proteína C reactiva (PCR), menor movilidad espinal, BASFI (Bath Ankylosing Spondylitis Functional Index) más elevado, afectación de la cadera con mayor frecuencia y alta prevalencia de baja por enfermedad. El 45,7% de los pacientes candidatos a tratamiento biológico no cumplían las recomendaciones de ASAS y el 48,6% los de la SER para el uso de anti-TNF. Los reumatólogos españoles consideraron como candidatos para el tratamiento con anti-TNFal 29,1 y el 29,6% de Ind los pacientes que no cumplían los criterios de ASAS y la SER, respectivamente. El criterio más importante fue la actividad clínica de la enfermedad. Conclusiones: La concordancia entre los criterios aplicados por los reumatólogos españoles y los propuestos por ASAS y SER es baja. Afectación axial, actividad y severidad de la enfermedad fueron los criterios usados más frecuentemente por los reumatólogos españoles para indicar terapia biológica en pacientes con EA (AU)

Objectives: To know the perception of Spanish rheumatologists of the profile of the patient with ankylosing spondyloarthritis, candidate for biological therapy treatment. To determine what proportion of patients with ankylosing spondylitis is considered a candidate for this therapy and to know up to what point this decision agrees with the recommendations of the ASAS working group on anti-TNF therapies and with the consensus of the SER Method: Rheumatologists from 19 Spanish centers who are experts in treating patients with AS and in the use of anti-TNF drugs participated in this study but they were not aware of the recommendations of the ASAS group and of the SER (unpublished until this work). Results: One hundred and eighty five patients were included in the study. Spanish rheumatologists indicated that they would start therapy with anti-TNF drugs in altogether 37.8% of the patients. The candidates had the highest values of disease activity, of acute-phase reactants, the worst spinal mobility, worst function, more hip damage, and high sick leave prevalence. Out of the total of the patients considered as candidates for treatment with biological therapies by their rheumatologists, 45.7% did not comply with the ASAS recommendations with respect to prior treatments with NSAIDs and BASDAI and 48.6% did not comply with the SER criteria; 29.1% of the patients who did not comply with the ASAS criteria (NSAIDs-BASDAI) were considered to be candidates for treatment with anti-TNF drugs; 29.6% of the patients who did not comply with the SER criteria were also considered to be candidates. The most important criterion was the clinical activity of the disease. Conclusions: The agreement between the criteria applied by the Spanish rheumatologist and proposed by ASAS working group and the SER consensus is low. Axial affectation, activity, and severity in their disease were the criteria used but frequently by the Spanish rheumatologist to indicate biological therapy in patients with AS (AU)
