Registro Iberoamericano de Espondiloartritis (RESPONDIA): Perú / RESPONDIA. Iberoamerican Spondyloarthritis Registry: Perú

Antecedentes: La importancia del estudio de las espondiloartritis en el Perú data de 1980. Se desconocen la frecuencia y la incidencia de la enfermedad, así como la presencia del antígeno de histocompatibilidad HLA-B27. Un estudio de prevalencia de enfermedades reumáticas en el Perú asigna a las espondiloartritis el 0,4%. Hemos encontrado presencia del HLA-B27 en el 33% de los pacientes. Objetivos: Describir las características clínicas, sociodemográficas, radiológicas y genéticas de los pacientes con espondiloartritis atendidos en el servicio de reumatología del Hospital Nacional Edgardo Rebagliati de Lima (Perú). Métodos: Análisis descriptivo y transversal de la información recogida acerca de pacientes peruanos con espondiloartritis entre enero de 2007 y diciembre de 2008, y almacenada en línea en la página electrónica del grupo REGISPONSER (Registro de Espondiloartritis de la Sociedad Española de Reumatología). Se utilizó el programa SPSS versión 13.0. Resultados: Se incluyó a 60 pacientes (39 varones [65%]) de 40 años de edad media. El diagnóstico establecido con más frecuencia fue espondilitis anquilosante y, en segundo lugar, espondiloartritis juvenil. El 31% tuvo reactividad al HLA-B27 y el 18,6% tenía historia familiar de espondiloartritis. Las extremidades inferiores se afectaron con más frecuencia, y la lumbalgia inflamatoria y el síndrome sacroilíaco fueron la afección axial más frecuente. Encontramos tarsitis en 31 pacientes (53,4%). El tratamiento más utilizado fue la sulfasalazina. Conclusión: Las características clínicas, demográficas y radiológicas de pacientes peruanos con espondiloartritis son similares a las encontradas en otros países iberoamericanos. La espondilitis anquilosante fue el diagnóstico más frecuente en varones y al 31% de los pacientes se les encontró HLA-B27 positivo (AU)

Background: The study of spondyloarthritis in Peru dates back to 1980. The frequency and occurrence of the illness is unknown, as is the presence of HLA-B27. A prevalence study of rheumatic diseases in Peru that looked for spondyloarthritis showed it to be 0,4%. HLAB27 was found in 33% of the patients. Objectives: To describe the clinical, socio-demographics, radiological and genetic characteristics of the patients with spondyloarthritis who are attended by the department of rheumatology at the Hospital Nacional E. Rebagliati in Lima-Perú. Methods: Descriptive analysis and transferring of the information gathered from Peruvian patients with spondyloarthritis between January 2007 and December 2008 stored in the electronic web page of REGISPONSER. SPSS version 13.0 was used for statistical analysis. Results: We included 60 patients (39 men [65%]) averaging 40 years of age. The diagnosis established with a higher frequency was ankylosing spondylitis and, in second place juvenile spondyloarthritis. Thirty one percent was related to HLA-B27 and 18.6% had a familiar history of spondyloarthritis. The lower extremities were affected with a higher frequency and inflammatory_back pain and sacroiliac syndrome were the most frequent axial manifestation. We encountered tarsitis in 31 patients (53.4%). The most utilized treatment was sulfasalazine. Conclusion: The clinical, demographics and radiological characteristics of Peruvian patients with spondyloarthritis are similar to those from other Latin-American countries. Ankylosing spondylitis is diagnosed most frequently in men and 31% are HLA-B27 positive (AU)

Obesity is independently associated with impaired quality of life in patients with rheumatoid arthritis.

Obesity is a modifiable major cause of morbidity and mortality in the general population, but little is known about the association of obesity and quality of life in patients with rheumatoid arthritis (RA). Thus, we set out a study to test the hypothesis that obesity is independently associated with lower quality of life in patients with RA. Three hundred and fifty nine patients with RA underwent an interview, physical exam, and all clinical charts were reviewed. Based on body mass index (BMI), patients were classified as normal (BMI < 25 kg/m(2)), overweight (BMI = 25-29.9 kg/m(2)), and obese (BMI > or = 30 kg/m(2)). Quality of life was quantified with the Medical Outcomes Study Short Form 36 (SF-36). Data obtained included demographic variables, extra-articular disease, comorbidities, presence of X-ray erosions, rheumatoid factor, and depression. The association between obesity and quality of life was examined with the use of multiple lineal regression models. One hundred and seventy-two patients (47.9%) had normal BMI, 126 (35.1%) were overweight, and 61 patients (17%) were obese. Obese patients had lower quality of life (30.8 +/- 18.1) than overweight patients (43.3 +/- 20.1) and patients with normal weight (43.8 +/- 22.2), P < 0.001. The association between obesity and impaired quality of life was confirmed with a linear regression model (Coef = -12.9, P < 0.001) and remained significant after adjustment for age, sex, disease activity, extra-articular disease, comorbidities, X-ray erosions, presence of rheumatoid factor, depression, education, and disease duration (Coef = -5.3, P = 0.039). In conclusion, obesity is independently associated with the impaired quality of life in patients with rheumatoid arthritis.
