Resumen

La diabetes mellitus está reconocida como un factor de riesgo de padecer sordera súbita neurosensorial. Su patogenia aún hoy no es conocida. Sin embargo, la implicación fisiopatológica de un síndrome de hiperviscosidad en diabéticos y en pacientes afectos de sordera súbita puede suponer el nexo de unión entre ambas entidades. La viscosidad sanguínea y la agregabilidad eritrocitaria fueron parámetros hemorreológicos que resultaron significativamente más elevados en sangre de diabéticos con sordera súbita que en controles normooyentes. Además, la filtrabilidad y la deformabilidad eritrocitaria fueron inferiores entre los diabéticos, pero no de forma estadísticamente significativa. Estos hallazgos pueden orientar el tratamiento en estos pacientes hacia medidas específicamente encaminadas a mejorar las propiedades viscoelásticas de la sangre.

Abstract

Diabetes mellitus is considered a risk factor for sensorineural sudden deafness. Its pathogenesis remains unknown. However, the physiopathological implication of a hyperviscosity syndrom in diabetics and patients bearing of sudden deafness can mean the nexus between the two entities. Total blood viscosity and erythrocyte adhesion were haemorheological parameters significatively higher in blood of diabetics with sudden deafness than in normal hearing controls. Moreover, erythrocyte filterability and deformability were lower in diabetics, but it was not statistically significative. These findings help to guide therapy in these patients towards specific measures to improve blood viscoelastic properties.

Key words:
Sudden deafness
Sensorineural hearing loss
Diabetes mellitus
