Filter by: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.
During the regular protocol of Intra-tympanic injections of Dexamethasone to the middle ear due to Sudden Sensorineural Hearing Loss, the patients will be sitted once after the injection instead of lying down. They will be then asked to rate their taste as a reference to the amount of fluid leaking to the throat through the eustachian tube.
The effect of the patient's head on the leakage of steroids from the middle ear to the throat will be studied. The patients will be seated after one of the intra tympanic injections that are routonely performed due to Sudden Sensorineural Hearin Loss (SNHL). The patients will be asked if they taste the steroids in their throats.
Idiopathic sudden sensorineural hearing loss (ISSNHL) is a complicated hearing impairment with unclear etiology and unsatisfying treatment effects. Vestibular dysfunction like vertigo has been considered as a risk factor of profound hearing loss and poor prognosis in ISSNHL. Glucocorticoids, administered through oral or intratympanic way, is currently a regular and standard treatment for ISSNHL based on hearing outcome. However, little investigations have been conducted on recovery process and treatment effects of glucocorticoids on vestibular dysfunctions of ISSNHL. This study aims to evaluate the recovery pattern and possible process of vestibular system in ISSNHL with vestibular dysfunction, and to compare the efficacy of oral or intratympanic glucocorticoids in these participants. A randomized, outcome assessor- and statistical analyst-blinded, controlled, clinical trial will be carried out. 72 patients complaining of vestibular dysfunction appearing as vertigo, dizziness, imbalance or lateropulsion with ISSNHL will be recruited and randomized into two arms of oral or intratympanic glucocorticoids therapy in 1:1 allocation. The primary outcomes will be subjective feelings evaluated by duration of vestibular dysfunction symptoms, dizziness-related handicap, visual analogue scale for vertigo, and objective vestibular function tests results assessed by sensory organization test, caloric test, video head impulse test and vestibular evoked myogenic potentials. Assessment will be performed at baseline and at 1, 2, 4, and 8 weeks post-randomization.
To evaluate ischemia-modified albumin levels in these patients to investigate the presence of ischemia in patients presenting with sudden hearing loss.
