Sudden Hearing Loss Clinical Trial
Official title:
Efficacy and Safety of Hydroxychloroquine in the Treatment of Sudden Sensorineural Hearing Loss
Sudden sensorineural hearing loss (SSNHL) is diagnosed when there's a sudden drop in hearing of at least 30 decibels across three consecutive frequencies, emerging within up to 72 hours. In clinical settings, steroids are the predominant treatment for SSNHL. However, the outcomes for patients undergoing steroid therapy for SSNHL can differ substantially. Moreover, a systematic review of randomized clinical trials has found no conclusive evidence pinpointing an effective treatment for SSNHL. Hydroxychloroquine, a derivative of chloroquine, is a medication that has gained attention for its potential role in modulating the immune response. We aim to see if hydroxychloroquine could augment hearing recovery in SSNHL under steroid treatment and to evaluate the safety of hydroxychloroquine in the treatment of SSNHL patients. We plan to enroll 80 SSNHL patients who received oral steroid therapy and randomize them into an experimental group (hydroxychloroquine with prednisolone, 40 patients) and a control group (prednisolone, 40 patients). The primary endpoint will be the change in pure tone audiogram (PTA) in the affected ear from screening until 3 months. The secondary endpoints will be the change in word recognition score and the change in bilateral tinnitus severity after treatment. Any side effects will be recorded to ensure the safety of this clinical trial.
Sudden sensorineural hearing loss (SSNHL) significantly affects a patient's social and interpersonal interactions. It presents as an abrupt decrease in hearing, usually within a matter of hours or days. SSNHL typically impacts one ear and can range in severity, sometimes resulting in total deafness. In clinical settings, steroids are the predominant treatment for SSNHL. Yet, the outcomes for patients undergoing steroid therapy for SSNHL can differ substantially. Hydroxychloroquine, a derivative of chloroquine, is a medication that has gained attention for its potential role in modulating the immune response. Our study hypothesized that hydroxychloroquine could help the hearing recovery during the steroid treatment for SSNHL. In this project, we will enroll two groups of subjects for our study. 1. Experimental group: Treatment with oral prednisolone (5 mg) for 14 days (high dosage 1 mg/kg/day for 7 days and gradually taper in the next week) and hydroxychloroquine for 60 days (400 mg/day) 2. Control group: Treatment with oral prednisolone (5 mg) for 14 days (high dosage 1 mg/kg/day for 7 days and gradually taper in the next week) A. Primary endpoint: The primary outcome measure for this study is the change in pure tone audiogram (PTA) in the affected ear from screening until 3 months. The PTA will be calculated as the arithmetic mean of air conduction thresholds at the frequency of 0.5k, 1k, 2k, and 4 kHz. B. Secondary endpoints: 1. the change in PTA in the bilateral ear from screening until one week, two weeks, one month, and two months 2. change in word recognition score (WRS) in the bilateral ear from screening to one week, two weeks, one month, two months and three months 3. The grade of hearing recovery by Siegel's criteria from screening to 3 months 4. Percentage of recovery from screening until 3 months 5. change in bilateral tinnitus severity (evaluted by VAS and THI) from screening to one month, 2 months and 3 months ;
