The patient journey of fibromyalgia in Latin America.

OBJECTIVES: To explore the patient journey of people with fibromyalgia (FM) in Latin American countries in order to identify problems in health care and other areas that may be resolvable. METHODS: Qualitative study with phenomenological and content analysis approach through focus groups and patient journey (Ux; User Experience) methodology. Nine virtual focus groups were conducted with FM patients and healthcare professionals in Argentina, Mexico and Colombia recruited from key informants and social networks. RESULTS: Forty-three people participated (33 were clinicians and 10 were patients). The agents interacting with the patient in their disease journey are found in three spheres: healthcare (multiple medical specialists and other professionals), support and work life (including patient associations) and socioeconomic context. The line of the journey presents two large sections, two loops and a thin dashed line. The two major sections represent the time from first symptoms to medical visit (characterized by self-medication and denial) and the time from diagnosis to follow-up (characterized by high expectations and multiple contacts to make life changes that are not realized). The two loop phases include (1) succession of misdiagnoses and mistreatments and referrals to specialists and (2) new symptoms every so often, visits to specialists, diagnostic doubts, and impatience. Very few patients manage to reach the final phase of autonomy. CONCLUSION: The journey of a person with FM in Latin America is full of obstacles and loops. The desired goal is for all the agents involved to understand that self- management by the patient with FM is an essential part of success, and this can only be achieved with early access to resources and guidance from professionals.

Falta de asociación entre inflamación subclínica evaluada por ultrasonido y niveles de citocinas en artritis reumatoide / Lack of association between ultrasound-defined subclinica inflammation and cytokines levels in rheumatoid arthritis

Antecedentes: La artritis reumatoide (AR) es una enfermedad autoinmune crónica que se caracteriza por proliferación sinovial, ruptura de cartílago y destrucción ósea. Los biomarcadores en AR no se utilizan en forma rutinaria para evaluar la inflamación y tampoco la remisión. El ultrasonido musculoesquelético (US) visualiza los cambios en las articulaciones y el daño morfoestructural, mejorando la evaluación de la sinovitis.Objetivo: Identificar y describir la inflamación subclínica en pacientes con AR en re-misión, utilizando US.Métodos: Se incluyeron pacientes con AR en remisión. Se realizó una evaluación clí-nica con DAS28; se tomó muestra de sangre para analizar citocinas. Un ecografista reumatólogo sin acceso a datos clínicos realizó un conteo ecográfico utilizando el sco-re-7. Se utilizaron parámetros de tendencia central, análisis de correlación bivariada y X cuadrado. Se estableció un nivel de confianza del 95% y, por tanto, cualquier valor p ≤0.05 se consideró significativo.Resultados: Se incluyeron 38 pacientes con AR. La edad media fue de 45,26±12,24 años. Los niveles de citocinas asociadas al tiempo de la AR desde la remisión, no fue-ron estadísticamente significativas. El ultrasonido en los pacientes evidenció al menos una de las lesiones elementales; en escala de grises, la sinovitis ocurrió en un 94,7%; sinovitis con señal Doppler de poder (DP) 52,6%; en cuanto a erosiones, se registra-ron, respectivamente, un 55,3% en escala de grises y un 15,8% con DP. DAS28 >2,04 fue positivo al asociarse con el recuento de articulaciones dolorosas y significativo (p=0,009). Conclusión: La asociación entre la sinovitis clínica y en ecografía no tiene correlación con los criterios de AR en remisión, independientemente de cuán estricta sea su aplicación.

Background: Rheumatoid arthritis (RA) is a chronic autoimmune disease, character-ized by synovial proliferation, cartilage breakdown and bone destruction. Biomarkers are not routinely used to evaluate inflammation neither remission. Musculoskeletal ultrasound visualizes joint changes and morpho-structural damage improving the as-sessment of synovitis.Objective: To identify and describe subclinical inflammation in patients with RA in remission using US.Methods: RA patients in remission were included. A clinical evaluation and DAS28 score performed; a blood sample took to analyze cytokines. A rheumatologist ultraso-nographer blinded to clinical data performed a US 7-score joint count. Central tenden-cy parameters, bivariate correlation analysis, and X Square were used. A confidence level of 95% was set and, therefore, any p-value ≤0.05 was considered as significant.Results: 38 RA patients were included. Mean age was 45.26±12.24 years. Cytokines associated with the time since remission was not statistically significant. Patients dis-played at least one of US elementary lesions; gray-scale synovitis occurred in 94.7%; synovitis with PD signal 52.6%; gray-scale erosions 55.3% and erosions with PD 15.8% respectively. DAS28 >2.04 positive for tender joint count was significant (p=0.009).Conclusion: The association between the clinical and US synovitis does not correlate with RA remission criteria no matter how strict is its application.

Terapia biológica, sobrevida y seguridad en padecimientos reumáticos. Resultados del Registro Nacional Biobadamex 1.0 / Patient survival and safety with biologic therapy. Results of the Mexican National Registry Biobadamex 1.0

Mediante registro multicéntrico ambispectivo de 2.047 pacientes con diversas afecciones reumáticas bajo terapia biológica (TxB), incluyendo un grupo control de pacientes con artritis reumatoide (AR) sin TxB, se reporta la supervivencia en la terapia y eventos adversos asociados a su uso. Los diagnósticos más frecuentes son: AR 79,09%; espondilitis anquilosante (EA) 7,96%; artritis psoriásica (APso) 4,40%; lupus eritematoso sistémico (LES) 3,37% y artritis idiopática juvenil (AIJ) 1,17 por ciento. Un análisis de 1.514 casos de la muestra total reportó que la tasa de incidencia para cualquier evento adverso es de 178/1.000 pacientes-año en TxB vs. 109/1.000 pacientes-año en controles con un riesgo relativo (RR) de 1,6 (IC del 95%, 1,4-1,9); para eventos adversos graves un RR de 15,4 (IC del 95%, 3,7-63,0 p < 0,0001). La supervivencia global de TxB es del 80% a 12 meses, el 61% a 24 meses, el 52% a 36 meses y el 45% a 48 meses. La tasa de mortalidad estandarizada (TME) es de 0,23 (IC del 95%, 0,0-49,0) para TxB vs. 0,00 (IC del 95%, 0,0-0,2) para controles. Se concluye que la TxB se asocia a un mayor riesgo de presentar eventos adversos, especialmente infecciosos, en comparación con pacientes sin TxB. La mortalidad de los pacientes expuestos a TxB no es mayor que la esperada para la población general ajustada a edad y sexo (AU)

This work reports patient treatment survival and adverse events related to Biologic Therapy (BT), identified by a multicenter ambispective registry of 2047 rheumatic patients undergoing BT and including a control group of Rheumatoid Arthritis (RA) patients not using BT. The most common diagnoses were: RA 79.09%, Ankylosing Spondilytis 7.96%, Psoriatic Arthritis 4.40%, Systemic Lupus Erythematosus 3.37%, Juvenile Idiopathic Arthritis 1.17%. A secondary analysis included 1514 cases from the total sample and was performed calculating an incidence rate of any adverse events of 178 × 1000/ BT patients per year vs. 1009 x 1000/control group patients per year with a 1.6 RR (IC95% 1.4-1.9). For serious adverse events the RR was: 15.4 (95% CI 3.7-63.0, P<.0001). Global BT survival was 80% at 12 months, 61% at 24 months, 52% at 36 months and 45% at 48 months. SMR: 0.23 (95%CI 0.0-49.0) for BT vs. 0.00 (95%CI 0.0-0.2) for the control group. In conclusion, BT was associated to a higher infection risk and adverse events, compared to other patients. Mortality using BT was not higher than expected for general population with same gender and age (AU)

[Guidelines in RA treatment: concepts on safety and recommendations using anti-TNF-alpha inhibitors. Grupo de Estudio de Nuevas Terapias de Enfermedades reumáticas (GENTE)]. / Recomendaciones para el tratamiento médico de la artritis reumatoide: actualización sobre la seguridad de los antagonistas del factor de necrosis tumoral alfa. Grupo de Estudio de Nuevas Terapias de Enfermedades reumáticas (GENTE).

Recommendations for the use of Disease-Modifying Antirheumatic Drugs (DMARD) with both conventional and biological agents in Rheumatoid Arthritis (RA) must be based on their safety profile, adverse effects, risks, and advantages. With the purpose of presenting the most updated information about the safety of tumor necrosis factor alpha (TNFalpha) antagonists, in this article we summarize the literature published during the last three years about this sort of biological agents in specific clinical situations, such as risk of developing infections, cancer, cardiovascular diseases, and autoimmunity; as well as their administration to patients who will undergo surgical procedures, pregnant and/or breast-feeding women, and patients who need immunizations. Likewise, in this analysis we offer specific recommendations, based on evidence, for the best anti-TNF-alfa management.

[Treatment guidelines for ankylosing spondylitis and its effect on Mexican rheumatology]. / Fundamentos para el tratamiento de la espondilitis anquilosante y su efecto en la reumatología mexicana.

We describe the guidelines for the current treatment of ankylosing spondylitis with an emphasis on the role and outlook of the Mexican rheumatologic community. The topics we analyze include: epidemiological as well as professional, financial, health status, and quality of life aspects. We propose to acknowledge that axial spondyloarthritis is the earliest form of ankylosing spondylitis. Finally we carry out a review of the literature supporting current therapeutic recommendations. Regarding the latter, we approached the ASAS/EULAR recommendations for the treatment of ankylosing spondylitis and their level of agreement with Mexican and other countries' rheumatologists. Finally, we analyzed the recommendations to start tumor necrosis alpha blockers among patients with ankylosing spondylitis.

Fundamentos para el tratamiento de la espondilitis anquilosante y su efecto en la reumatología mexicana / Treatment guidelines for ankylosing spondylitis and its effect on Mexican rheumatology

Esta revisión trata de los fundamentos sobre los que descansa el tratamiento actual de la espondilitis anquilosante, enfatizando la participación y la opinión de la comunidad reumatológica nacional. En la temática se incluye la repercusión de la enfermedad —aspectos epidemiológicos, laborales, económicos, estado de salud y calidad de vida—, propuestas para la identificación de la espondiloartritis axial como la forma más precoz de la espondilitis anquilosante y el análisis de la literatura que dio origen a las recomendaciones terapéuticas actuales. Con relación al último punto, se abordan las recomendaciones ASAS/EULAR para el tratamiento de la espondilitis anquilosante y el nivel de concordancia con la opinión del reumatólogo mexicano y de otros países. Finalmente, se analizan las recomendaciones para iniciar bloqueadores del factor de necrosis tumoral en pacientes con espondilitis anquilosante.

Rheumatoid arthritis treatment with weekly leflunomide: an open-label study.

OBJECTIVE: To assess the safety and effectiveness of leflunomide (LNF) using 100 mg/week in patients with rheumatoid arthritis (RA). METHODS: Patients who were clinically active using the American College of Rheumatology criteria for RA were enrolled. They received a loading dose of 100 mg of LFN for 3 days, followed by 100 mg of LFN weekly. Efficacy and adverse events (AE) were recorded. RESULTS: Fifty patients were enrolled; 46 (93.6%) were women with a mean age of 45.6 years (range: 24 to 83). Disease duration was 3.7 years (range: 0.5 to 12). Twenty patients (40.8%) had previously taken disease modifying antirheumatic drugs. Outcomes achieved after 24 weeks of treatment were as follows: ACR20 (74%), ACR50 (64%), and ACR70 (28%). Five patients were withdrawn due to AE: 2 due to urticaria, 2 patients had elevated liver enzymes, and one had thrombocytopenia. Six patients (12%) were lost to followup. No severe AE were seen. CONCLUSION: The results in our preliminary report indicate that using a 100 mg/week dose achieves a similar benefit to the LFN 20 mg/day treatment, and there were no severe AE. In addition, a single LFN weekly dose has better treatment compliance. A secondary important benefit is the reduction of the monthly cost of medication. Comparative and blind trials are necessary in order to confirm longterm improvement and benefits on this regimen.
