[Deafness in the Muckle-Wells syndrome]

Area of Science:

• Genetics and rare diseases
• Otolaryngology
• Nephrology

Background:

• Muckle Wells syndrome (MWS) is a rare autoinflammatory disorder.
• Characterized by a triad of recurrent fevers, urticaria-like rash, and sensorineural hearing loss.

Observation:

• The syndrome presents with progressive hearing loss, arthralgia, urticarial eruptions, and renal amyloidosis.
• Incomplete forms of MWS may lack deafness or renal amyloidosis.
• Perceptive deafness is likely due to inner ear pathology, though histological data is limited.

Findings:

• Hearing loss onset varies within families but is often age-specific.
• Renal amyloidosis is a significant complication, impacting kidney function.
• Mixed hearing loss (conductive and perceptive) can occur in some cases.

Implications:

• Understanding incomplete MWS is crucial for accurate diagnosis.
• Further audiological analysis in larger cohorts is needed to fully define MWS hearing characteristics.
• Early identification and management of MWS can prevent severe complications like renal failure.
