3. Patients must be capable of understanding and giving informed consent.
4. Patients must have SNHL of greater than or equal to 30dB at three contiguous frequencies in one ear which evolved in three days or less, with a PTA of 25dB or less in the contralateral ear.

Patients must have demonstrated less than a 5 decibel average improvement in their PTA in response to corticosteroids as measured by their audiogram.
6. NO greater than 30 days may elapse from the discontinuation from the initial course of steroid treatment to the time of enrollment.

Exclusion Criteria:

1. Patients over 75 years of age, because there is a higher incidence of infections in the elderly population in general, caution should be used in treating the elderly.

7. Patients with a diagnosis of chronic renal insufficiency (a creatinine clearance of <49mL/min) or chronic renal failure.
8. Patients with evidence of neutropenia (an ANC of <1000) prior to treatment with anakinra.
9. Known hypersensitivity to E. coli derived products.
10. Latex sensitivity.
11. Any patient that received a live vaccine < 3 months prior to enrollment.
12. Any patient with a history of active narcotic abuse, including prescription narcotics.
