RESUMO

OBJECTIVE: To determine the clinical efficacy and safety of Leflunomide (LFN) 100 mg/week compared to low dose Methotrexate (MTX) 10 mg/week in a double-blind, randomized, controlled trial with 52 weeks of follow up in Rheumatoid Arthritis (RA) patients. PATIENTS AND METHODS: Patients who met ARC1987 criteria for RA were included. All patients had medical records, including laboratory tests and hand X-rays. Clinical evaluations for improvement and ACR and EULAR response criteria were performed. Statistical analysis for independent's samples between both groups defined a P value of ≤.05. Safety was evaluated by comparing the proportion of adverse events (AE) registered. RESULTS: Of 90 patients screened; five were withdrawn; the remaining 85 patients were randomised: 43 LFN and 42 MTX. Sixty-three patients completed the study; 72% in the LFN group and 74.4% in the MTX group. ACR20 improvement criteria were achieved by LFN group in 90.3%, and in MTX 78.1% (P=.14) at week 52. EULAR improvement criteria applied at the end point showed a DAS28 score for the LFN group of 3.45, and for the MTX group was 3.67(P=.43). Total withdrawals, including loss during follow up, AE and lack of efficacy for each group was 12 patients in the LFN group, and 10 patients in the MTX group. Regarding safety, no serious AE of a life threatening nature were reported. CONCLUSIONS: These outcomes confirm that LFN 100 mg/week offers an adequate and sustained improvement effect on the clinical manifestations of RA, similar to low dose treatment with MTX 10 mg/every week after 52 weeks of follow up; it may be a good therapeutic option alone or in combination with others anti-rheumatic drugs.

RESUMO

Las neumonía eosinofílica se clasifica por su presentación en aguda o crónica; las características distintivas se basan en la presencia de tos, disnea, fiebre e infiltrados pulmonares con acumulación de células inflamatorias, predominante de eosinófilos. La asociación de eosinofilia y padecimientos reumatológicos es bien conocida, como en el caso de la fascitis eosinofílica y el síndrome de Churg-Strauss. La coexistencia de neumonía eosinofílica crónica y artritis reumatoide ha sido reportada, ya sea de inicio coincidente o en artritis reumatoide establecida. El papel fisiopatológico de los eosinófilos en las enfermedades autoinmunes no está bien definido, sin embargo se ha demostrado que la producción de citocinas proinflamatorias estimulan y activan diferentes grupos celulares, pudiendo en forma simultánea inducir autoanticuerpos e incremento y/o infiltración de eosinófilos en diversos tejidos, sin tener una enfermedad autoinmune subyacente. Presentamos el caso de una mujer joven con neumonía eosinofílica crónica con manifestaciones clínicas reumatológicas y presencia de autoanticuerpos, que se resolvió en forma espontánea (AU)


Eosinophilic pneumonia is classified by its acute or chronic presentation, the distinguishing characteristics of which are based on the presence of cough, dyspnea, fever and pulmonary infiltrates with accumulation of inflammatory cells, predominantly eosinophils. The association of eosinophilia and rheumatologic disorders is well known, as in the case of eosinophilic fasciitis and the Churg-Strauss syndrome. The coexistence of chronic eosinophilic pneumonia and rheumatoid arthritis has been reported, either early rheumatoid arthritis of definitive disease. The pathophysiological role of eosinophils in autoimmune diseases is not well defined, however it has been shown that the production of pro-inflammatory cytokines stimulate and activates different cell groups, and can simultaneously induce autoantibodies and/or increased infiltration of eosinophils in various tissues, without an underlying autoimmune disease. The case of a young woman with rheumatic chronic eosinophilic pneumonia manifestations and the presence of autoantibodies, which resolved spontaneously, is presented here (AU)

RESUMO

Introducción: La fascitis eosinofílica (FE) es una enfermedad de origen desconocido, caracterizada por induración de la piel, debido a inflamación de las fascias del tejido conjuntivo. Afecta principalmente a las extremidades y se acompaña de elevación de inmunoglobulinas y eosinofilia periférica. Objetivo: Evaluar la eficacia de ciclosporina A en pacientes con FE con resistencia al tratamiento convencional con glucocorticoides. Pacientes y método: Presentamos 3 pacientes con manifestaciones clínicas y serológicas de FE que tuvieron resistencia al tratamiento estándar con glucocorticoides (30 a 50 mg/día, durante un período de hasta 8 meses). Las manifestaciones clínicas principales fueron: induración de la piel de las extremidades y el tronco que se acompañó de eosinofilia periférica y elevación de la creatincinasa. Histológicamente se observó un engrosamiento con intensa inflamación linfocitaria de las fascias. Resultados: Todos los pacientes fueron tratados con ciclosporina A, a dosis de 5 a 7 mg/kg/día con una rápida mejoría clínica (2 meses). El tratamiento condujo, en todos los casos, a una remisión clínica que permitió reducir e incluso retirar la ciclosporina A durante el seguimiento. Conclusiones: La ciclosporina A parece una alternativa terapéutica eficaz en el tratamiento de pacientes con FE resistente a glucocorticoides (AU)


Introduction: Eosinophilic fasciitis (EF) is a disease of unknown aetiology characterized by cutaneous swelling and indurations. The disease affects predominantly the extremities and usually show an elevation of serum immunoglobulins, and eosinophilia. Objective: Evaluation of the efficacy of cyclosporine A as a therapeutic alternative in patients with EF refractory to steroids. Patients and method: We report 3 patients with clinical, laboratory and pathologic characteristics of EF who did not show a satisfactory response to steroids treatment. All patients disclosed scleroderma-like signs with orange skin, groove sign, and indurations of the affected extremities associated to peipheral eosinophilia and increased creatine-kinase. Epidermis histological findings were normal and intense linfocitary inflammation of the fascia was observed in all patients’ biopsies. All patients were treated for average of 8 months with prednisone 30-50 mg daily with an insufficient clinical response. Results: Patients started on cyclosporine A 5-7 mg/kg/day, showing a fast improvement (2 months). The treatment induces a clinical remission that permits to reduce or even stops the cyclosporine A treatment during follow-up. Conclusions: It seems that cyclosporine A may be a effective therapeutic alternative in patients with EF refractory to steroids (AU)

RESUMO

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.

RESUMO

Las Artritis Juveniles son un grupo heterogéneo de padecimientos que a través del tiempo han venido recibiendo diferentes nombres y se han tratado de agrupar de diversas maneras; sin embargo, no se ha logrado un consenso internacional para lograr este fin y es conocida la intención de establecer una clasificación que permita el estudio y seguimiento de estas artritis. En Europa y Estados Unidos de América se han propuesto diferentes clasificaciones en las que han participado algunas organizaciones como el Colegio Americano de Reumatología, la Organización Mundial de la Salud y la Liga Europea contra el Reumatismo. Preocupados por lograr una clasificación que permitiera el estudio de estos padecimientos, la Liga Internacional de Asociaciones de Reumatología formó una fuerza de trabajo para proponer una nueva clasificación; la última reunión de este grupo en Durban, Sudáfrica en 1997 generó una última propuesta de clasificación de la que se aquí se hace una revisión y comparación con clasificaciones previas.

RESUMO

Objetivo: La artritis reumatoide (AR) es una enfermedad multifactorial y sistémica del tejido conjuntivo. Caracterizada por afección simétrica de las articulares pequeñas de las manos y pies, en etapas tardías puede también involucrar articulaciones mayores. La afección es dada básicamente por un proceso inflamatorio. La AR es más frecuente en mujeres (2 a 7 veces). Los antígenos leucocitarios humanos (HLA) están involucrados en la patología de la enfermedad. El HLA es parte del complejo principal de histocompatibilidad (CPH), localizado en el brazo corto del cromosoma 6. El CPH se ha subdividido en 3 grupos. Las moléculas clase II se expresan en los linfocitos B, linfocitos T activados, macrófagos, células de Langerhans, dendríticas y endoteliales. El objetivo principal del presente estudio fue buscar una asociación entre éstos antígenos y la AR en paciente adultos del sexo masculino. Métodos. Se incluyeron 35 pacientes de sexo masculino cuya edad media fue de 45.2 años (rango de 25 a 67), con diagnóstico de AR (según los cirterios del ACR) que asisten a la consulta del Servicio de Reumatología del Hospital Regional 20 de noviembre del ISSSTE, estudiados en forma prospectiva de junio de 1989 a julio de 1990. Se estudió la clase funcional, la clase anatómica y se determinó la presencia del factor reumatoide. Resultados: Los resultados fueron: clase funcional I en 17.1 por ciento, II en 60 por ciento, III en 20 por ciento y IV en 28 por ciento. Todos los pacientes fueron seropositivos para factor reumatoide tipo IgM por nefelometría. Los antígenos de histocompatibilidad Clase II fueron: DR5 en 25 por ciento, DR4 en 15 por ciento y DR3 y DR7 en 13.3 por ciento

RESUMO

La parálisis periódica tirotóxica es una manifestación clínica poco común de la tirotoxicosis que afecta principalmente a las poblaciones de origen asiático; el reconocimiento de este trastorno puede prevenir consecuencias desastrosas en los pacientes. En México nosostros sólo encontramos cuatro casos descritos en la literatura; aquí reportamos dos casos vistos en nuestro hospital, así como los hallazgos asociados en histocompatibilidad leucocitaria, los que difieren de los descritos en otras publicaciones
