Overview
Brief Summary
Ménière's disease is an inner ear disorder in which patients suffer from attacks of vertigo, tinnitus and hearing loss. To date, it is unclear what the best treatment for this condition is. Giving injections in the inner ear with the adrenal cortical hormone methylprednisolone is a treatment that is already widely used, but still there is insufficient evidence in the effectiveness of this treatment. This multicenter trial compares a patient group which receives injections of methylprednisolone to a patient group which receives placebo injections. Subsequently, dizziness, tinnitus, hearing loss and quality of life will be assed and compared for the above mentioned groups, over a period of one year.
Detailed 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.

Outcomes
Primary Outcomes
Vertigo spells
Time Frame: 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 Outcomes
- health-related quality of life(At baseline, 6 months and 12 months)
- Impact of Dizziness(Change from baseline to 6 months to 12 months)
- Hearing loss(At baseline, 6 months and 12 months)
- Adverse events(Daily, change from baseline to one year)
- Co-interventions(Daily, change from baseline to one year)
- Escape medication(At baseline, 3 months, 6 months, 9 months, 12 months)
- Tinnitus(At baseline, 6 months and 12 months)
- Cost-effectiveness(At baseline, 6 months and 12 months)
- Tinnitus severity(At baseline, 6 months and 12 months)
- Overall function(At baseline, 6 months and 12 months)
