Enfermedad por arañazo de gato en paciente con artritis reumatoidea tratado con etanercept / Cat scratch disease during etanercept therapy in a rheumatoid arthritis patient

La enfermedad por arañazo de gato (EAG) es una enfermedad infecciosa causada por la proteobacteria Bartonella henselae, caracterizada por fiebre y linfadenopatía granulomatosa. La inmunosupresión es un factor de riesgo para el desarrollo de formas atípicas de la enfermedad. Presentamos el caso de una mujer de 52 años de edad que presentó fiebre y adenomegalias inguinales bilaterales. No tenía contacto aparente con animales. La paciente estaba recibiendo tratamiento con etanercept por artritis reumatoidea. La biopsia del ganglio linfático informó de una adenopatía granulomatosa. Evolucionó favorablemente con la interrupción de etanercept y el tratamiento con minociclina. Presentó remisión clínica y la seroconversión típica. La infección por Bartonella debería ser considerada como un diagnóstico diferencial en pacientes con artritis reumatoidea, con linfadenopatía de origen desconocido

Cat scratch disease (CSD) is an infectious disorder caused by Bartonella henselae and characterized by fever and granulomatous lymphadenopathy. Immunosuppression is a risk factor for the development of atypical forms of the disease. We report the case of a 52-year-old woman who presented with fever and bilateral inguinal lymph node enlargement. She did not have apparent contact with animals. The patient was receiving etanercept therapy for rheumatoid arthritis. Lymph node biopsy demonstrated granulomatous lymphadenitis. She was successfully managed by discontinuing etanercept and by treatment with minocycline. She developed clinical remission and typical seroconversion. Infection with Bartonella should be considered in the differential diagnosis in rheumatoid arthritis patients with lymphadenopathy of unknown origin

Association of diffuse idiopathic skeletal hyperostosis and aortic valve sclerosis.

The principal objective of this investigation was to analyze the association between diffuse idiopathic skeletal hyperostosis (DISH) and the presence of aortic valve sclerosis (AVS). For this study we used results from 1000 consecutive outpatients (473 males), older than 50 years of age (average 67.6 years), that had been examined with Doppler echocardiogram and anterior and lateral chest radiographs. Overall, 195 patients (19.5%) were diagnosed with DISH and 283 (28.3%) with AVS. DISH was more prevalent than AVS in males (66.7% vs. 42.6%, p< 0.0001) and in older patients (73.6 ± 9 years vs. 66.1 ± 9 years, p < 0.0001). Furthermore, 55.4% of patients with dorsal DISH presented aortic sclerosis calcification vs. 21.7% of patients free of DISH (OR = 4.47; 95% CI = 3.22-6.21). The adjusted odds ratio (OR) was calculated by sex and age resulting in 3.04 (95% CI = 2.12-4.36; p < .0001). A statistically significant association was found between DISH and AVS in accordance to age and sex. The biological plausibility of this association is based on similar risk factors, pathogenic mechanisms and vascular complications.

El objetivo principal fue analizar la asociación entre la hiperostosis esquelética idiopática difusa (DISH) y la presencia de esclerosis valvular aórtica (AVS). Se evaluaron los resultados de 1000 pacientes ambulatorios consecutivos (473 varones), mayores de 50 años (promedio, 67.6 años), que habían sido examinados con un ecocardiograma Doppler y radiología torácica anterior y lateral. Globalmente, 195 pacientes (19.5%) tuvieron diagnóstico de DISH y 283 (28.3%) de AVS. DISH fue más prevalente que AVS en varones (66.7% vs. 42.6%, p < 0.0001) y en pacientes de mayor edad (73.6 ± 9 años vs. 66.1 ± 9 años, p < 0.0001). Además, 55.4% de los pacientes con DISH dorsal presentaron AVS vs. 21.7% de los pacientes sin DISH (OR = 4.47; 95% CI = 3.22-6.21). El odds ratio (OR) ajustado por sexo y edad fue 3.04 (95% CI = 2.12-4.36; p < 0.0001). Se encontró una asociación estadísticamente significativa entre DISH y AVS, que se mantuvo después de ajustar por sexo y edad. La plausibilidad biológica de esta asociación se basa en los factores de riesgo, mecanismos patogénicos y complicaciones vasculares compartidos.
