Serum osmolality in Menière's disease
Abstract:
Serum osmolality in patients with Meniere's disease was measured by a Wescore 5100B osmometer to reveal the relationship between a vertiginous attack, the effect of isosorbide, the effect of glycerol, and the osmolality. The following results were obtained: First, the osmotic pressure of the control group ranged from 275 mOsm/kg to 285 mOsm/kg, and that of the Meniere's group ranged from 270 mOsm/kg to 290 mOsm/kg. Both groups showed normal distribution, and mean values of both were 284 mOsm/kg. There was no statistically significant difference between them with regard to serum osmolality. Second, patients with values of 283 mOsm/kg or less were more often in a vertiginous attack period, and patients with values of 284 mOsm/kg or more were more often in an attack-free period. Third, patients with values of 283 mOsm/kg or less were more often in the positive glycerol test group; those with values of 284 mOsm/kg or more were more often in the negative glycerol test group. Finally, there was no significant difference in serum osmolality between patients receiving isosorbide therapy and patients given no treatment.
Insights
Serum osmolality in Meniere
Area of Science:
- Otolaryngology
- Nephrology
- Endocrinology
Background:
- Meniere's disease is characterized by episodic vertigo.
- Serum osmolality may play a role in Meniere's disease pathophysiology.
Purpose of the Study:
- To investigate the relationship between serum osmolality and Meniere's disease.
- To explore the correlation of serum osmolality with vertiginous attacks and glycerol test results.
Main Methods:
- Serum osmolality was measured in patients with Meniere's disease and a control group using a Wescore 5100B osmometer.
- Correlation analysis was performed between serum osmolality, vertiginous attack status, and glycerol test outcomes.
Main Results:
- No significant difference in mean serum osmolality was found between Meniere's disease patients and controls.
- Lower serum osmolality (≤283 mOsm/kg) was associated with vertiginous attacks and positive glycerol tests.
- Higher serum osmolality (≥284 mOsm/kg) correlated with attack-free periods and negative glycerol tests.
- Isosorbide therapy did not significantly alter serum osmolality.
Conclusions:
- Serum osmolality may be a potential biomarker for Meniere's disease activity.
- Lower serum osmolality might indicate a predisposition to vertiginous attacks in Meniere's disease patients.
- Further research is needed to elucidate the role of osmolality in Meniere's disease management.
