RESUMEN

ABSTRACT Tocilizumab (TCZ), an 1interieukin-6 receptor-α Inhibitor, is Indicated in patients with moderate to severe rheumatoid arthritis with inadequate response to disease modifying drugs. ACT UP is a multinational project co11ecting information from severa1 post-marketing TCZ studies. Aim: To determine the proportion of patients in the routine clinical care setting receiving intravenous TCZ after 6 months treatment. Identification of TCZ treatment patterns, efficacy, and safety were also recorded. Method: This prospective non-interventional 6-month study, collected real-world information from 169 Central American and Caribbean patients. No interventional procedures or additional visits outside routine clinical care practice were performed. Statistical analysis was essentially descriptive. Results: Adherence rate was 74.0%, with 97% of patients receiving TCZ as first biological therapy line and there were no deviations from the local label. Almost 85% of patients started with combination therapy, and the majority remained under this scheme throughout the study. A significant decrease in disease activity assessments and acute phase reactants values were detected during TCZ treatment. The percentage of patients that achieved improvement according to the different levels of the American College of Rheumatology (ACR) increased during the study, and relevant enhancements in quality of life were also accomplished. Adverse events (AEs) occurred in 35 patients, with metabolic and nutritional disorders being the most common. Serious AEs were reported in 3% of patients, and special interest AEs occurred in 6 patients. Conclusion: Treatment adherence was mainly determined by follow-up and compliance with the administration schedule. Efficacy analysis showed better results than those reported in international literature. The incidence of AEs was also lower than in previously published data.

RESUMEN El tocilizumab (TCZ) está indicado en la artritis reumatoide moderada a severa, principalmente en respuestas inadecuadas a fármacos convencionales. ACT UP es un proyecto multinacional que recopila información relacionada con varios estudios de poscomercialización. Objetivo: Determinar la proporción de pacientes en la atención clínica de rutina que continúan en tratamiento con TCZ intravenoso después de 6 meses. Se llevó a cabo la identificación de patrones de administración, eficacia y seguridad. Método: Este estudio observacional prospectivo recopiló información de la vida real de 169 pacientes de América Central y el Caribe. No se hicieron intervenciones ni visitas adicionales fuera de la práctica clínica habitual. El análisis estadístico fue esencialmente descriptivo. Resultados: La tasa de adherencia al tratamiento fue del 74,0%, el 97% de los pacientes reci bieron TCZ como primera línea biológica y no existieron desviaciones en las indicaciones de administración según el inserto local. Aproximadamente el 85% de los pacientes inició TCZ como terapia combinada, y la mayoría permaneció bajo este esquema. Se evidenció una dis minución en la actividad de la enfermedad y un aumento en el porcentaje de pacientes que lograron respuesta según los diferentes grados del Colegio Americano de Reumatología. En 35 pacientes se presentaron eventos adversos (EA), siendo los relacionados con metabolismo y nutrición los más comunes. Se informaron EA graves en el 3% de los pacientes y de interés especial en 6 casos. Conclusión: El seguimiento de los pacientes y el cumplimiento del programa fueron los prin cipales determinantes en la adherencia. El análisis de eficacia mostró mejores resultados que los reportados previamente y la incidencia de EA fue menor que en otros estudios.

RESUMEN

This study aimed to perform an overview of how ultrasound (US) is being used, implemented, and applied in rheumatologic centers in Latin America (LA). A retrospective, multicenter 1-year experience study was undertaken. Eighteen centers from eight countries were involved. The following information were collected: demographic data, indication to perform an US examination, physician that required the examination, and the anatomical region required for the examination. A total of 7167 patients underwent an US examination. The request for US examinations came most frequently from their own institution (5981 (83.45 %)) than from external referral (1186 (16.55 %)). The services that more frequently requested an US examination were rheumatology 5154 (71.91 %), followed by orthopedic 1016 (14.18 %), and rehabilitation 375 (5.23 %). The most frequently scanned area was the shoulder in 1908 cases (26.62 %), followed by hand 1754 (24.47 %), knee 1518 (21.18 %), ankle 574 (8.01 %), and wrist 394 (5.50 %). Osteoarthritis was the most common disease assessed (2279 patients (31.8 %)), followed by rheumatoid arthritis (2125 patients (29.65 %)), psoriatic arthritis (869 patients (12.1 %)), painful shoulder syndrome (545 (7.6 %)), connective tissue disorders (systemic sclerosis 339 (4.7 %), polymyositis/dermatomyositis 107 (1.4 %), Sjögren's syndrome 60 (0.8 %), and systemic lupus erythematosus 57 (0.8 %)). US evaluation was more frequently requested for diagnostic purposes (3981 (55.5 %)) compared to follow-up studies (2649 (36.9 %)), research protocols (339 (4.73 %)), and invasive guided procedures (198 (2.76 %)). US registered increasing applications in rheumatology and highlighted its positive impact in daily clinical practice. US increases the accuracy of the musculoskeletal clinical examination, influence the diagnosis, and the disease management.

RESUMEN

At the end of 2013, the Pan American Health Organization issued an epidemiological alert due to the detection of the first local cases of Chikungunya in the Americas. By August 2015, autochthonous transmissions were detected in 33 countries and territories of the Americas. Latin America has reported nearly one million cases; only Colombia has issued a report of >200,000 cases during the first 4 months of 2015. In some Latin American and Caribbean countries, Chikungunya becomes a major public health problem. The disease commonly exhibits a self-limited course of arthritis, usually lasting for a few days or that may be prolonged to weeks; however, in 10-60 % of cases, joint pain may become chronic and persist for up to 3-5 years. Human-caused environmental changes, such as climate change, the globalization of international exchange, and disordered urban growth, are some factors that aid in its emergence and dissemination. Outbreaks of Chikungunya comprise a challenge for health care systems and rheumatologists because of the high attack rate on the population and the anticipated development of post-Chikungunya chronic rheumatism. This review emphasizes the rheumatologic clinical manifestations reported in the American continent and highlights the challenges that health care systems face in the absence of an effective vaccine and specific treatment to fight Chikungunya.

RESUMEN

La mano y la muñeca tienen anatomía y función muy complejas que la hacen susceptible a diversas lesiones de tejidos blandos y también representan áreas anatómicas que con frecuencia son afectadas por enfermedades de etiología diversa, como artritis inflamatoria, degenerativa y por depósitos de cristales. La ultrasonografía representa una técnica de imagen muy útil para el estudio de la mano y muñeca por su capacidad multiplanar, sin emisión de radiaciones y de bajo costo, características que le dan ventaja sobre otras técnicas.

The hand and wrist are very complex anatomy and function that make it susceptible to various soft tissue injuries and also represent anatomical areas are often affected by diseases of different etiologies as inflammatory arthritis, degenerative and crystal deposits. Ultrasonography is a useful imaging technique for the study of the hand and wrist by its multiplanar capability, without emission of radiation and low-cost features that give an advantage over other techniques.

RESUMEN

OBJECTIVE: To develop guidelines for Musculoskeletal Ultrasound (MSKUS) training for rheumatologists in the Americas. METHODS: A total of 25 Rheumatologists from 19 countries of the American Continent participated in a consensus-based interactive process (Delphi method) using 2 consecutive electronic questionnaires. The first questionnaire included the following: the relevance of organizing courses to teach MSKUS to Rheumatologists, the determination of the most effective educational course models, the trainee levels, the educational objectives, the requirements for passing the course(s), the course venues, the number of course participants per instructor, and the percentage of time spent in hands-on sessions. The second questionnaire consisted of questions that did not achieve consensus (>65%) in the first questionnaire, topics, and pathologies to be covered at each course MSKUS level. RESULTS: General consensus was obtained for MSKUS courses to be divided into 3 educational levels: basic, intermediate, and advanced. These courses should be taught using a theoretical-didactic and hands-on model. In addition, the group established the minimum requirements for attending and passing each MSKUS course level, the ideal number of course participants per instructor (4 participants/instructor), and the specific topics and musculoskeletal pathologies to be covered. In the same manner, the group concluded that 60% to 70% of course time should be focused on hands-on sessions. CONCLUSION: A multinational group of MSKUS sonographers using a consensus-based questionnaire (Delphi method) established the first recommendations and guidelines for MSKUS course training in the Americas. Pan-American League of Associations for Rheumatology urges that these guidelines and recommendations be adopted in the future by both national and regional institutions in the American continent involved in the training of Rheumatologists for the performance of MSKUS.
