RESUMO

OBJECTIVE: In this study, we aimed to investigate endothelial functions in primary Sjögren syndrome. METHODS: Thirty-five patients with primary Sjögren syndrome and 20 age and sexmatched healthy volunteers were recruited to the present study. Flow mediated dilatation of brachial artery and carotid intimamedia thickness were measured in the study population. RESULTS: Carotid intimamedia thickness values were similar between groups (0.50 ± 0.10, 0.53 ± 0.08, p > 0.05). Flow mediated dilatation of the brachial artery was disrupted in the primary Sjögren syndrome group (7% vs 12%, p = 0.002). CONCLUSION: There is endothelial dysfunction in patients with primary Sjögren syndrome, although they had comparable carotid intimamedia thickness with the healthy control group.


OBJETIVO: Este estudio se encaminó a investigar las funciones endoteliales en el síndrome de Sjögren primario. MÉTODOS: Para el presente estudio, se reclutaron treinta y cinco pacientes con síndrome de Sjögren primario y 20 voluntarios sanos apareados por edad y sexo. La dilatación mediada por flujo observada en la arteria braquial, y el espesor íntimamedia carotídeo fueron medidos en la población bajo estudio. RESULTADOS: Los valores del espesor íntimamedia carotídeo fueron similares entre los grupos (0.50 ± 0.10, 0.53 ± 0.08, p > 0.05). La dilatación mediada por flujo de la arteria braquial, estaba alterada en el grupo de síndrome del Sjögren primario (7% frente a 12%, p = 0.002). CONCLUSIÓN: Hay una disfunción endotelial en los pacientes con el síndrome de Sjögren primario, aunque estos tenían un espesor íntimamedia carotídeo comparable con el grupo de control saludable.
