Glycerin and urea tests in Meniere's disease. A multifactorial analysis using a quantification method

Area of Science:

• Biochemistry
• Audiology
• Medical Diagnostics

Background:

• Biomarkers like glycerin and urea are used in medical diagnostics.
• Understanding correlations between patient factors and test results is crucial for accurate diagnosis.

Purpose of the Study:

• To investigate the relationship between patient age, disease duration, hearing loss, and positive glycerin and urea tests.
• To determine the diagnostic utility of glycerin and urea tests based on patient characteristics.

Main Methods:

• A quantification method for multidimensional qualitative data was employed.
• 13 variables were analyzed, including patient age, disease duration, hearing loss levels (dB), and results of glycerin and urea tests.

Main Results:

• Younger patients showed a stronger correlation between age and positive glycerin/urea tests; no correlation was found in patients over 50.
• Longer disease duration correlated with positive urea tests, but not glycerin tests.
• Hearing losses of 40-69 dB correlated with both tests; greater losses correlated only with glycerin tests; losses <39 dB showed no correlation.

Conclusions:

• Age and disease duration are significant factors influencing the interpretation of glycerin and urea tests.
• Hearing loss severity is associated with specific biomarker test outcomes, indicating potential for integrated diagnostic approaches.
