Study Description

Meniere's disease is an inner ear disease characterized by recurrent episodes of vertigo, hearing loss, tinnitus and aural fullness. It is estimated that 15000 patients in de Netherlands suffer from this disease. Endolymfactic hydrops is thought to be the underlying pathophysiology of the symptoms. Salt restriction, oral medication (diuretics and betahistine), intratympanic gentamicin and steroids, ablative surgery, and endolymphatic sac surgery are some of the current therapy options. A probable effectiveness of the treatment with intratympanic gentamicin is found but this treatment is ototoxic and carries a risk of hearing loss. Methylprednisolone injections have been shown to be safer, however there is insufficient data to support the efficacy of this treatment. Therefore in this double-blinded, randomized, placebo-controlled trial, effectiveness of intratympanic injections with methylPREDnisolon versus placebo in the treatment of vertigo attacks in MENière's disease is compared.

The investigators aim to include 74 patients in each arm, based on a statistical power of 80 percent. Patients will be randomly randomized to one of the two treatment arms, receiving either a placebo injection or a methylprednisolone sodium succinate injection at a dose of 62.5 mg/ml. After 14 days, this injection will be given once more. A follow-up visit will be scheduled after six and twelve months and telephone follow-up calls will be scheduled after three and nine months. The primary objective will be the control of vertigo, with secondary outcomes including hearing loss, tinnitus, the frequency of escape interventions, quality of life, adverse events and cost effectiveness.

Outcome Measures

Primary Outcome Measures

1. Vertigo spells [Daily, change from baseline to one year]
   A definitive vertigo spell is defined as a spontaneous rotational vertigo symptom, which lasts at least 20 minutes and is often accompanied by disequilibrium and vomiting. No loss of consciousness is present. Vertigo spells are measured daily with the dizzy quest ap. Futhermore, at baseline after 6 and 12 months, caloric testing and a video-head impusle test are performend. Additionally the dizziness handicap inventory will be taken.

Secondary Outcome Measures

1. Hearing loss [At baseline, 6 months and 12 months]
   Hearing loss will be measured at baseline, 6 and 12 months after injection. Pure tone audimetry and extended fletcher index including the speech discrimination score will be tested.
2. Tinnitus [At baseline, 6 months and 12 months]
   Tinnitus will be measured with the tinnitus handicap inventory at baseline, after 6 and 12 months.
3. health-related quality of life [At baseline, 6 months and 12 months]
   The health realted quality of life will be evaluated with the generic quality of life questionnaire: EQ-5D
4. health-related quality of life [At baseline, 6 months and 12 months]
   The health realted quality of life will be evaluated with the generic quality of life questionnaire: EQ-VAS, this will be a scale from 0 to 100 in which 0 means the worst health you can imagine and 100 means the best health you can imagine
5. Escape medication [At baseline, 3 months, 6 months, 9 months, 12 months]
   The frequency of use of metoclopramide in the acute phase of vertigo will be registered.
6. Adverse events [Daily, change from baseline to one year]
   At each study visit, subjects will be questioned about adverse events they have experienced since the last study visit.
7. Cost-effectiveness [At baseline, 6 months and 12 months]
   Costs per QALY, this will be calculated from above mentioned outcomes on quality of life.
8. Co-interventions [Daily, change from baseline to one year]
   The use of additional methylprednisolon or gentamicine will be evaluated during the entire study.
9. Overall function [At baseline, 6 months and 12 months]
   The functional level scale will be measured with the questionnaire: Functional level scale: a scale from 1-6 in which 1 means: my dizziness has no effect on my activities and 6 means: I have been disabled for one year or longer and/or I received compensation (money) because of y dizziness or balance problem.
10. Impact of Dizziness [Change from baseline to 6 months to 12 months]
    The impact of dizziness will be measured with the questionnaire: Dizziness handicap inventory
11. Tinnitus severity [At baseline, 6 months and 12 months]
    The tinnitus severety will be measured with the questionnaire: Tinnitus functional index
