Clinical associations of serum antiendothelial cell antibodies in patients with sudden sensorineural hearing loss.

Objectives/hypothesis: The role of antiendothelial cell antibodies in systemic vasculitis has been reported. The aim of the study was to define the clinical associations of serum antiendothelial cell antibodies in patients with sudden sensorineural hearing loss.

Study Design: A prospective study in patients with sudden sensorineural hearing loss.

Early diagnosis and stage-adapted treatment of Wegener's granulomatosis.

A case of Wegener's granulomatosis (WG) presenting with hearing loss and right facial nerve palsy is reported. The definitive diagnosis was based upon clinical data and serum cANCA and AECA detection. Early assessment of WG prevented surgical facial nerve decompression to treat a chronic otitis media complication.

[Role of endothelial cell autoantibodies in the pathogenesis of sudden hear loss].

Sudden hearing loss can be found in systemic autoimmune diseases or it can be a symptom of an autoimmune disease of the inner ear. The present work has studied a group of patients with idiopathic sudden hearing loss to determine what role anti-endothelial cell antibodies (AECA) play as markers of immuno-mediated vasculitis of the inner ear. The study involved 32 patients with sudden deafness and 14 controls.

Anti-endothelial autoantibodies in patients with sudden hearing loss.

Objectives/hypothesis: Sudden hearing loss (HL) can be caused by autoimmune disorders localized to the inner ear or secondary to systemic immune diseases. Studies in autoimmune animal strains showing HL have reported changes in the cochlear stria vascularis. The authors investigated the presence of antiendothelial cell antibodies (AECA) to see if immune-mediated vasculitis may play a role in human sudden HL.
