Audiological Patterns in Patients with Autoimmune Hearing Loss.

Area of Science:

• Otolaryngology
• Immunology
• Genetics

Background:

• Autoimmune hearing loss (AIHL) is a complex condition affecting hearing through immune-mediated mechanisms.
• Understanding the clinical and audiological profiles of AIHL is crucial for diagnosis and management.

Purpose of the Study:

• To delineate the clinical and audiological characteristics of patients diagnosed with autoimmune hearing loss (AIHL).
• To identify factors influencing hearing recovery in AIHL patients undergoing steroid treatment.

Main Methods:

• Retrospective analysis of 53 patients diagnosed with AIHL.
• Evaluation of clinical symptoms, audiological patterns, autoimmune markers (ANA, HLA), and treatment outcomes.
• Logistic regression analysis to correlate clinical and laboratory features with hearing recovery.

Main Results:

• Progressive hearing loss was the most common onset (49%), followed by sudden (39.6%) or fluctuating (11.3%).
• A downsloping audiogram pattern was most frequent (42.6%).
• Recurrent, bilateral sudden sensorineural hearing loss (SSHL) was associated with a negative effect on hearing recovery (OR = 0.042).

Conclusions:

• AIHL frequently manifests as bilateral, simultaneous, progressive hearing loss with a downsloping audiogram.
• Recurrent, bilateral SSHL in AIHL patients signifies a worse prognostic indicator for hearing recovery.
