A Two-Year Randomized Trial of Interventions to Decrease Stress Hormone Vasopressin Production in Patients with...

Area of Science:

• Inner ear disorders
• Endocrinology
• Neuroscience

Background:

• Meniere's disease is a common inner ear condition.
• Vasopressin, a stress hormone, is implicated in Meniere's disease.
• Current treatments focus on stress management, which can be challenging for patients.

Purpose of the Study:

• To investigate novel therapeutic interventions for Meniere's disease.
• To explore the management of vasopressin secretion as a treatment strategy.
• To compare the efficacy of water intake, tympanic ventilation tubes, and sleeping in darkness against traditional medication.

Main Methods:

• A randomized-controlled, open-label pilot study.
• 297 Meniere's disease patients enrolled between 2010-2012.
• Four groups: traditional medication, abundant water intake, tympanic ventilation tubes, sleeping in darkness.
• 2-year follow-up assessing vertigo, hearing, plasma vasopressin, and stress factors.

Main Results:

• Vertigo control was significantly higher in the water intake, ventilation tube, and darkness groups (81.4%, 84.1%, 80.0%) compared to the control group (54.3%).
• Hearing improvement was also significantly greater in the intervention groups (35.7%, 34.9%, 31.7%) versus the control (7.1%).
• Plasma vasopressin levels decreased more in intervention groups, despite no change in reported stress levels.

Conclusions:

• Abundant water intake, tympanic ventilation tubes, and sleeping in darkness show promise for Meniere's disease treatment.
• These interventions effectively decrease vasopressin secretion, leading to improved vertigo and hearing.
• Managing vasopressin secretion offers a feasible alternative to stress management for Meniere's disease.
