[Study on the correlation of substance P in middle ear effusion and clinical presentation in secretory otitis media]
1Department of Otorhinolaryngology, 401 Hospital of PLA, Qingdao, 266100, China.
Objective:
To investigate the correlation of substance P in middle ear effusion and clinical presentation in secretory otitis media.
Method:
Observation on relation between clinical presentation (the course of disease, the hearing loss, quantity of middle ear effusion or quality) and substance P (SP) content of middle ear effusion (MEE) in 64 cases (79 ears) of secretory otitis media (SOM).
Result:
SP concentration of MEE in serous group was remarkably higher than that in the mucous group (P < 0.01). SP concentration of MEE had positive correlation with the volume (r = 0.985, P < 0.01), and negative correlation with the course of disease (r = -0.6217, P < 0.01). The hearing loss of mucous group was remarkably higher than that of the serous group (P < 0.01). SP concentration of MEE in serous group had positive correlation with auditory threshold (r = 0.9553, P < 0.01). SP concentration of MEE in mucous had no correlation with auditory threshold.
Conclusion:
SP might play an important role in SOM. The detection of SP content in MEE is of important significance for judging quality of MEE and understanding the course of disease.
Insights
Substance P (SP) levels in middle ear fluid correlate with secretory otitis media (SOM) severity. Higher SP concentrations indicate more fluid but a shorter disease course, aiding diagnosis.
Area of Science:
- Otolaryngology
- Neuroscience
- Biochemistry
Context:
- Secretory otitis media (SOM) is a common condition, particularly in children.
- The pathophysiology of SOM involves inflammation and fluid accumulation in the middle ear.
- Understanding the role of neuropeptides like substance P (SP) in SOM is crucial.
Purpose:
- To investigate the correlation between substance P (SP) levels in middle ear effusion (MEE) and the clinical presentation of secretory otitis media (SOM).
- To determine if SP concentration can serve as a biomarker for MEE quality and disease progression.
Summary:
- A study of 64 SOM cases found significantly higher SP concentrations in serous MEE compared to mucous MEE.
- SP concentration positively correlated with MEE volume and negatively with disease duration.
- Hearing loss was greater in the mucous group, with SP correlating to auditory threshold in the serous group but not the mucous group.
Impact:
- Findings suggest SP plays a significant role in the pathogenesis of SOM.
- Measuring SP in MEE can aid in assessing MEE quality and understanding disease course.
- This research contributes to a better understanding of SOM biomarkers.

Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
