start of 1:1-Block public summary

Brief Summary in Lay Language

According to recent studies, in Germany the annually cases of sudden idiopathic sensorineural hearing loss has been estimated to be 160 to 400 per 100.000. Idiopathic sudden sensorineural hearing loss (ISSHL) is one of the most frequent causes of sensorineural hearing loss. Although sensorineural hearing impairment can be partially compensated by hearing aids (HA) or cochlear implants (CI), hearing without these aids is better with respect to sound quality and communication ability. In addition, tremendous costs for society are associated with communication disorders in general and with both aids, specifically. Systemic steroids are widely used worldwide as standard of care for primary therapy of ISSHL. However, scientific data did not demonstrate a clear efficacy of any of these therapies. The German ISSHL-Guideline recommends high dose steroid (250mg Prednisolone or equivalent steroid dose) for primary therapy of ISSHL, which has not been proven so far in high-quality scientific studies. This three-armed trial is aimed to compare standard dose with two types of high-dose steroids for systemic therapy with respect to their efficacy in improving hearing, and thus communication ability in patients with idiopathic sudden sensorineural hearing loss. It is to be tested, if high-dose treatments show superiority as compared to standard treatment.
In the course of a protocol amendment, the following changes were made in October 2017: - adjustment or clarification of the inclusion / exclusion criteria. The amendment was approved by the ethics committee of the Medical Faculty of the Martin-Luther-University Halle Wittenberg on 05.10.2017.

Brief Summary in Scientific Language

According to recent studies, in Germany the incidence of sudden idiopathic sensorineural hearing loss has been estimated to be 160 to 400 per 100.000. Idiopathic sudden sensorineural hearing loss (ISSHL) is one of the most frequent causes of sensorineural hearing loss. Although sensorineural hearing impairment can be partially compensated by hearing aids (HA) or cochlear implants (CI), generic hearing is better with respect to sound quality and communication ability. In addition, tremendous costs for society are associated with communication disorders in general and with both, HAs and CI, specifically. Systemic steroids are widely used worldwide as standard of care for primary therapy of ISSHL. However, their assessment in reviews, meta-analysis and RCTs did not demonstrate a clear efficacy of any of these therapies. The German ISSHL-Guideline recommends high dose steroid (250mg Prednisolone or equivalent steroid dose) for primary therapy of ISSHL, which has not been proven so far in RCTs. The rationale for the treatment of ISSHL using high dose steroids is only based on retrospective cohort studies. This three-armed trial is aimed to compare standard dose with two types of high-dose steroids for systemic therapy with respect to their efficacy in improving hearing, and thus communication ability in patients with idiopathic sudden sensorineural hearing loss.
