Controlled clinical trial of pentoxifylline versus cinnarizine in the treatment of labyrinthine disorders.

Seventy-six patients with labyrinthine diseases of vascular origin were treated in a 6-week double-blind comparative study with either 400 mg pentoxifylline ('Trental') or 75 mg cinnarizine 3-times daily. Clinical evaluations, supported by audiological tests and vectornystagmography, were carried out before and after treatment. Statistical analysis of the results showed pentoxifylline to be globally superior to cinnarizine and especially to have a more intense antivertiginous effect. No significant differences were observed between the two drugs in respect of tinnitus and hearing loss therapy. Side-effects were occasional, mild and well tolerated in the pentoxifylline group, and more pronounced and frequent with cinnarizine.

Glucose, insulin and inner ear pathology.

One hundred consecutive patients with a clinical suspicion of metabolic inner ear disorder were submitted to a 5-hour glucose tolerance test with simultaneous titration of insulin. It was found that 82% of the patients presented abnormal glucose and/or insulin values. The analysis of the results revealed hypo- or hyperglycemia were present in only 41% of the cases, and that all patients had normal fast values for glucose. Hyperinsulinemia was the most frequent abnormality and was found to constitute the determining factor of the inner ear disorders. 26 of the patients presented Meniere's disease. The pathophysiological model for insulin-induced Meniere's disease is discussed. Follow-up data indicate that these patients respond well to a diet with reduced intake of small molecule carbohydrates.
