Summary
Reduced red blood cell deformability (RCD) may contribute to sudden sensorineural deafness, particularly in patients with recent infections. Further research is needed to explore RCD testing for sudden hearing loss diagnosis and treatment.
Area of Science:
- Otorhinolaryngology
- Hematology
- Vascular Medicine
Background:
- Sudden sensorineural deafness (SSD) is often idiopathic, with potential contributing factors under investigation.
- Red blood cell deformability (RCD) is crucial for microcirculation and may be affected by various conditions.
Purpose of the Study:
- To investigate the role of Red blood cell deformability (RCD) in patients diagnosed with sudden sensorineural deafness.
- To explore potential links between RCD, infections, and the etiology of sudden sensorineural deafness.
Main Methods:
- Red blood cell deformability (RCD) was assessed using a filtration technique.
- Patient cohort included 12 individuals diagnosed with sudden sensorineural deafness.
Main Results:
- Five out of 12 patients exhibited reduced red blood cell deformability (RCD).
- Reduced RCD was observed in 3 out of 4 patients with a recent upper respiratory tract infection.
- The findings suggest RCD may be a complicating factor rather than a primary cause of sudden sensorineural deafness.
Conclusions:
- Reduced red blood cell deformability (RCD) may play a role in the pathophysiology of sudden sensorineural deafness.
- A potential link between viral infections, vascular factors, and idiopathic sudden sensorineural deafness is proposed.
- RCD testing could be a valuable addition to the diagnostic work-up for sudden sensorineural deafness, pending further therapeutic advancements.
