Patients with non-idiopathic sudden sensorineural hearing loss show hearing improvement more often than patients with idiopathic sudden sensorineural hearing loss.

ABSTRACT:

Introduction

To compare inpatient treated patients with idiopathic (ISSNHL) and non-idiopathic sudden sensorineural hearing loss (NISSNHL) regarding frequency, hearing loss, treatment and outcome.

Methods

All 574 inpatient patients (51% male, median age: 60 years) with ISSNHL and NISSNHL, who were treated in federal state Thuringia in 2011 and 2012, were included retrospectively. Univariate and multivariate statistical analyses were performed.

Results

ISSNHL was diagnosed in 490 patients (85%), NISSNHL in 84 patients (15%). 49% of these cases had hearing loss due to acute otitis media, 37% through varicella-zoster infection or Lyme disease, 10% through Menière disease and 7% due to other reasons. Patients with ISSNHL and NISSNHL showed no difference between age, gender, side of hearing loss, presence of tinnitus or vertigo and their comorbidities. 45% of patients with ISSNHL and 62% with NISSNHL had an outpatient treatment prior to inpatient treatment (p < 0.001). The mean interval between onset of hearing loss to inpatient treatment was shorter in ISSNHL (7.7 days) than in NISSNHL (8.9 days; p = 0.02). The initial hearing loss of the three most affected frequencies in pure-tone average (3PTAmax) scaled 72.9 dBHL ± 31.3 dBHL in ISSNHL and 67.4 dBHL ± 30.5 dBHL in NISSNHL. In the case of acute otitis media, 3PTAmax (59.7 dBHL ± 24.6 dBHL) was lower than in the case of varicella-zoster infection or Lyme disease (80.11 dBHL ± 34.19 dBHL; p = 0.015). Mean absolute hearing gain (Δ3PTAmax_abs) was 8.1 dB ± 18.8 dB in patients with ISSNHL, and not different in NISSNHL patients with 10.2 dB ± 17.6 dB. A Δ3PTAmax_abs ≥ 10 dB was reached in 34.3% of the patients with ISSNHL and to a significantly higher rate of 48.8% in NISSNHL patients (p = 0.011).

Conclusions

ISSNHL and NISSNHL show no relevant baseline differences. ISSNHL tends to have a higher initial hearing loss. NISSHNL shows a better outcome than ISSNHL.

Project description:ImportancePatients with idiopathic sudden sensorineural hearing loss (ISSNHL) often experience permanent hearing impairment, which could result in psychological perturbations. However, the relationship between ISSNHL and affective disorders, including depression, anxiety, and bipolar disorder, has not been fully evaluated.ObjectiveTo investigate the potential relationship between ISSNHL and affective disorders using nationwide representative cohort sample data.Design, setting, and participantsThis study used a nationwide propensity score-matched cohort sample from the Korean National Health Insurance Service database from 2002 through 2013, which comprises data from approximately 1 million patients. The study included 1425 patients with ISSNHL and 7125 individuals without ISSNHL who were matched using propensity score matching, according to sociodemographic factors and enrollment year.Main outcomes and measuresSurvival analysis, the log-rank test, and Cox proportional hazards regression models were used to calculate the incidence, survival rate, and hazard ratio (HR) of developing affective disorders (anxiety, depression, and bipolar disorder) for each group.ResultsOf the total study population of 8550 (51.5% female), 961 developed affective disorders during the 11-year follow-up: 225 in the ISSNHL group (15.8%) and 736 in the comparison group (10.3%). We examined a total of 96 885.5 person-years (81 177.4 person-years in the comparison group and 15 708.1 person-years in the ISSNHL group). The incidence of affective disorders was 14.3 per 1000 person-years in the ISSNHL group and 9.1 per 1000 person-years in the comparison group. After adjustment for other factors, individuals with ISSNHL developed affective disorders more frequently than those in the comparison group (HR, 1.50; 95% CI, 1.30-1.75). Among the affective disorders, the HR of developing depression (HR, 1.66; 95% CI, 1.44-1.91) and anxiety disorder (HR, 1.79; 95% CI, 1.56-2.05) but not bipolar disorder (HR, 0.95; 95% CI, 0.54-1.70), was significantly greater in patients with ISSNHL.Conclusions and relevanceThis cohort study suggests that ISSNHL is associated with an increased incidence of affective disorders, specifically depression and anxiety. Therefore, these findings suggest that clinicians should monitor patients with ISSNHL carefully, and take specific precautions to reduce their risk of depression and anxiety disorder.

Project description:BACKGROUND:Hearing loss is one of the leading causes of disability worldwide. Patients with hearing loss experience impaired quality of life, as well as emotional and financial consequences that affect both themselves and their families. Idiopathic sudden sensorineural hearing loss (ISSNHL) is a common but difficult to treat condition that has a sudden onset of ≤ 72 hour associated with various etiologies, with the majority of cases being idiopathic. There exists a wide range of therapeutic options, however, the uncertainty surrounding their comparative efficacy and safety makes selection of treatment difficult. This systematic review and network meta-analysis (NMA) assessed the relative effects of competing treatments for management of ISSNHL. METHODS:A protocol for this review was registered with PROSPERO (CRD42017073756). A detailed search of MEDLINE, Embase and the Cochrane Library from inception to February 8th, 2018 was carried out by an experienced information specialist. Grey literature was also searched. Screening full-text records, and risk of bias assessment were carried out independently by two reviewers, and disagreements were resolved through consensus or third party adjudication, while data was collected by one reviewer and verified by a second reviewer. Bayesian network meta-analyses (NMA) were performed to inform comparisons between interventions for a priori specified outcomes that included pure tone average (PTA) improvement and hearing recovery. RESULTS:The search identified a total of 1,138 citations, of which 613 remained for review after removal of duplicates. Of these, 23 publications describing 19 unique studies (total sample size of 1,527) met our a priori eligibility criteria, that were assessed to be at unclear or high risk of bias on several domains. We identified data on several interventions for ISSNHL therapy and were able to construct treatment networks consisting of six intervention groups that included placebo; intratympanic (IT) steroid; IT plus systemic steroid; per oral (PO) steroid; intravenous (IV) steroid; and IV plus PO steroid for our NMAs. IT plus systemic steroids demonstrated the largest difference in PTA improvement compared to placebo (25.85 dB, 95% CrI 7.18-40.58), followed by IV plus PO steroids (22.06 dB, 95% CrI 1.24-39.17), IT steroids (18.24 dB, 95% CrI 3.00-29.81). We observed that the difference of PTA improvement between each intervention and placebo diminished over time, attributed to spontaneous recovery. The binary outcomes of hearing recovery demonstrated similar relative ordering of interventions but were less sensitive than PTA improvement to capture the significant differences between interventions and placebo. CONCLUSION:Unclear to high risk of bias trials rated IT plus systemic steroid treatment as the best among the six interventions compared, and all active treatments were better than placebo in improving PTA. However, it should be noted that certain comparisons were based on indirect evidence only or few studies of small sample size, and analyses were unable to control for steroid type and dosage. Given these limitations, further data originating from methodologically sound and rigorous trials with adequate reporting are needed to confirm our findings.
