Assessing the Efficacy of a Serotonin and Norepinephrine Reuptake Inhibitor for Improving Meniere's Disease Outcomes
Study Details
Study Description
Brief Summary
As of yet, the cause of Meniere's disease is uncertain and there is no cure. Given the lack of high level evidence for treatments, we seek to perform a randomized, placebo-controlled, double-blind, crossover, pilot trial of venlafaxine for treating Meniere's disease. Venlafaxine is a safe and well-tolerated medication. It has never been trialed in Meniere's disease, but there is evidence that it could be effective in helping with vertigo attacks and other aspects of the disorder.

Outcome Measures
Primary Outcome Measures
- Change in Score on Dizziness Handicap Inventory (DHI) [Baseline to end of treatment (6 months)]
The Dizziness Handicap Inventory is a 25-item questionnaire of self-perceived handicap from dizziness.There are 7 questions in the physical domain, 9 in the emotional domain, and 8 in the functional domain. It is scored from 0 (no perceived disability) to 100 (maximum perceived disability).
- Change in Score on Neuropsychological Vertigo Inventory (NVI) [Baseline to end of treatment (6 months)]
The English version of the Neuropsychological Vertigo Inventory consists of 28-items with a 5-point Likert scale for each question. It is a cognitive assessment specific to patients with dizziness. The NVI assesses 7 domains of cognition: space perception, attention, time perception, memory, emotional, visual/ocular and motor. The score ranges from 0 to 140. The higher the score on the NVI the worse the cognitive function of the subject.
- Change in Score on Cognitive Failure Questionnaire (CFQ) [Baseline to end of treatment (6 months)]
The Cognitive Failure Questionnaire is a 25-item survey which assesses cognitive and executive function not tied to any specific disease state. It aims to assess perception, memory, and motor function in everyday tasks.The score ranges from 0 to 100 The higher score on the CFQ, the more frequent the cognitive failures experienced by the subject
- Change in Score on Patient Health Questionnaire (PHQ9) [Baseline to end of treatment (6 months)]
The Patient Health Questionnaire is a 9-item survey which assesses the severity of depression. A low score is indicative of little to no depressive symptoms, and a high score is indicative of Moderately severe to severe depressive symptoms. Scores range from 0 to 27 with scores higher than 20 indicative of significant risk for depression and scores below 10 indicative at most of a mild depression.
- Change in Score on Penn State Worry Questionnaire (PSWQ) [Baseline to end of treatment (6 months)]
The PSWQ is a 16-item survey for assessment of anxiety which has been used to identify generalized anxiety disorder. Scores range from 16 (Low worry) to 80 (high worry). A score higher than 60 is indicative of significant anxiety and risk for an anxiety disorder
- Change in Score on The Meniere's Disease Patient-Oriented Symptom Index (MDPOSI) [Baseline to end of treatment (6 months)]
The Meniere's Disease Patient-Oriented Symptom Index is a 23-item survey developed as a MD-specific tool to assess the impact of MD symptoms on patients' lives. The score ranges from 0 to 100 with the higher score indicating an active disease with significant impact on function and quality of life.
- Change in Score on The Medical Outcomes Study 20-item Short Form Health Survey [Baseline to end of treatment (6 months)]
The Medical Outcomes Study 20-item Short Form Health Survey is a 20-item general health questionnaire to assess quality of life in chronic diseases. It assesses 6 areas of health: physical functioning, role functioning, social functioning, mental health, health perceptions, and pain. Scores range between 0 and 100, with 100 indicating best possible function and 0 the worst possible function
- Number of Vertigo Episodes [6 months]
Patients will be keeping a diary throughout the study period and beyond.
- Severity of Vertigo [6 months]
The study team will use a modified version of vertigo control classification because the treatment phases are 2 months long and the study team will not be able to wait 18-24 months after treatment to assess efficacy per academy guidelines. Previous studies have defined four categories of response to treatment: 1) very good response if more than 75% reduction in vertigo spells frequency and/or intensity, 2) good response if 50-75% reduction, 3) fair response if 25-50% reduction, and 4) poor response if less than 25% reduction. The vertigo classes will be defined as follows; Class A: 0 (complete control of vertigo) Class B: 0-40 or >60% reduction in mean vertigo episode severity (good control of vertigo) Class C: 41-80 or 20-60% reduction in severity (fair control of vertigo) Class D: 81-120 or -20-20% reduction in severity (no change in vertigo) Class E: >120 or >20% worsening in severity (worse vertigo)
