Project description:ObjectiveTo evaluate the impact of gentamicin exposure on sensorineural hearing loss (SNHL) in very low birth weight (VLBW) infants.MethodsExposure to gentamicin was determined in infants born between 1993 and 2010 at a gestational age < 32 weeks and/or with a birthweight < 1500 g, who presented with SNHL during the first 5 years of life. For each case, we selected two controls matched for gender, gestational age, birthweight, and year of birth.ResultsWe identified 25 infants affected by SNHL, leading to an incidence of SNHL of 1.58% in our population of VLBW infants. The proportion of infants treated with gentamicin was 76% in the study group and 70% in controls (p = 0.78). The total cumulated dose of gentamicin administered did not differ between the study group (median 10.2 mg/kg, Q1-Q3 1.6-13.2) and the control group (median 7.9 mg/kg, Q1-Q3 0-12.8, p = 0.47). The median duration of gentamicin treatment was 3 days both in the study group and the control group (p = 0.58). Maximum predicted trough serum levels of gentamicin, cumulative area under the curve and gentamicin clearance were not different between cases and controls.ConclusionThe impact of gentamicin on SNHL can be minimized with treatments of short duration, monitoring of blood levels and dose adjustment.

Project description:ObjectivesThis systematic review summarises the evidence on the correlation between recurrent acute otitis media (rAOM) or chronic suppurative otitis media (CSOM) and sensorineural hearing loss (SNHL).Research methodsPubMed, Embase and Cochrane Library databases were searched from inception to 15 January 2021. Two authors independently identified articles, extracted data and performed quality assessment for included studies. Studies comparing the sensorineural hearing levels of patients with a history of rAOM/CSOM for >3 months to a control group were included.ResultsScreening of 4168 articles lead to inclusion of two case-control studies (control-group: patients non-OM) and seven cohort-studies (control group: contralateral ear). Quality assessment indicated considerable risk of bias in all studies. Reported populations varied (sample size 13-607, mean age 22-41.5 years, mean duration of disease 6.1-12.4 years). The OR for SNHL in the OM-group was 3.30-7.86 (95% CI 1.16 to 9.40, p<0.05) in cohort studies (n=2), and 0.05 (95% CI 0 to 0.78, p<0.05) in a case-control study. Mean/median bone conduction thresholds were respectively 1.19-32.21/0-10 dB higher on all frequencies (0.5-4 kHz) for the OM-group in four cohort studies (p<0.05). Two other studies reported no statistical test outcomes.ConclusionDue to the high risk of bias of included studies, effect estimates heterogeneity and suboptimal research designs, no conclusion on the correlation between OM and SNHL can be made. It emphasises the need for future prognostic studies.

Project description:BackgroundSeveral recent studies speculated that the gut microbiota is associated with sensorineural hearing loss (SNHL) and proposed the concept of the gut-inner ear axis. However, the causal effect of gut microbiota on SNHL is still unknown. In this study, we performed a two-sample Mendelian randomization (MR) analysis to estimate the causal effect of gut microbiota on SNHL.MethodsGut microbiota data were obtained from the largest available genome-wide association study (n = 18,340) conducted by the MiBioGen consortium. The summary statistics of SNHL were obtained from the FinnGen consortium R8 release data (28,310 cases and 302,750 controls). The causal effects were estimated with inverse-variance weighted, MR-Egger, and weighted median. Reverse Mendelian randomization analysis was performed on the bacteria that were found to be associated with SNHL in forward Mendelian randomization analysis. We then performed sensitivity analyses, including Cochran's Q-test, MR-Egger intercept test, MR-PRESSO, cML-MA-BIC, and leave-one-out analysis, to detect heterogeneity and pleiotropy.ResultsThe inverse-variance weighted results suggested that Lachnospiraceae (UCG001) had a significant protective effect against SNHL (odds ratio = 0.85, 95% confidence interval: 0.78-0.93, P = 6.99 × 10-4). In addition, Intestinimonas (odds ratio = 0.89, 95% confidence interval: 0.82-0.97, P = 8.53 × 10-3) presented a suggestively protective effect on SNHL. Rikenellaceae (RC9gutgroup) (odds ratio = 1.08, 95% confidence interval: 1.02-1.15, P = 0.01) and Eubacterium (hallii group) (odds ratio = 1.12, 95% confidence interval: 1.00-1.24, P = 0.048) suggestively increase the risk of SNHL. The results of the reverse MR analysis showed that there is no significant causal effect of SNHL on the gut microbiota. No significant heterogeneity of instrumental variables or pleiotropy was detected.ConclusionThe evidence that the four genera mentioned above are associated with SNHL supports the hypothesis of a gut-inner ear axis. Our study provides microbial markers for the prevention and treatment of SNHL, and further studies are needed to explore the mechanisms of the gut microbiome-inner ear axis in health and diseases.

Project description:ObjectiveEvidence shows that anemic individuals are at a higher risk of hearing loss. However, there is no systematic review and meta-analysis study. Thus, we aimed to meta-analyze the existing evidence on the association of iron deficiency anemia (IDA) with sensorineural hearing loss (SNHL). We searched PubMed, MEDLINE, Embase, Scopus, and Google Scholar from inception through October 30, 2017, for studies done on the association of the IDA with SNHL. Pooled odds ratio (OR) was calculated by random effect meta-analysis method. Heterogeneity was assessed by I2 metrics.ResultFour studies, covering a total of 344,080 adults and children, were included. The odds of SNHL was higher by 55% in individuals with IDA, compared with individuals without IDA (OR = 1.55, 95% CI 1.17-2.06; P = 0.03). The age-specific ORs were 1.36 (95% CI 1.15-1.61; P = 0.27) and 3.67 (95% CI 1.72-7.84) for adults and children, respectively. IDA may be a contributing factor to hearing loss. Further studies are warranted, including whether IDA treatment reduces the risk of hearing loss. Meanwhile, hearing loss screening in anemic individuals, or vice versa, may represent an important consideration. PROSPERO registration CRD42017082108.

Project description:ObjectivesThe pathology of sudden sensorineural hearing loss, which is known as sudden deafness (SD), remains unknown. The purpose of this study was to investigate the association between mitochondrial uncoupling protein 2 (UCP2) polymorphism and SD risk.Materials and methodsWe compared 83 patients suffering from SD and 2048 controls who participated in the Longitudinal Study of Aging at the National Institute for Longevity Sciences. Multiple logistic regression was used to calculate the odds ratios (ORs) for SD with a polymorphism of the UCP2 (rs660339) gene.ResultsUnder the additive model of inheritance, UCP2 polymorphisms showed significant association with a SD risk. The OR was 1.468 (95% confidence interval, 1.056-2.040) with an adjustment for any past history, such as diabetes, dyslipidemia, or hypertension, and for age and sex.ConclusionOur results imply that the UCP2 (rs660339) polymorphism has a significant association with the risk of developing SD.

Project description:ImportanceSensorineural hearing loss (SNHL) is commonly caused by conditions that affect cochlear structures or the auditory nerve, and the genes identified as causing SNHL to date only explain a fraction of the overall genetic risk for this debilitating disorder. It is likely that other genes and mutations also cause SNHL.ObjectiveTo identify a candidate gene that causes bilateral, symmetric, progressive SNHL in a large multigeneration family of Northern European descent.Design, setting, and participantsIn this prospective genotype and phenotype study performed from January 1, 2006, through April 1, 2016, a 6-generation family of Northern European descent with 19 individuals having reported early-onset hearing loss suggestive of an autosomal dominant inheritance were studied at a tertiary academic medical center. In addition, 179 unrelated adult individuals with SNHL and 186 adult individuals reporting nondeafness were examined.Main outcomes and measuresSensorineural hearing loss.ResultsNine family members (5 women [55.6%]) provided clinical audiometric and medical records that documented hearing loss. The hearing loss is characterized as bilateral, symmetric, progressive SNHL that reached severe to profound loss in childhood. Audiometric configurations demonstrated a characteristic dip at 1000 to 2000 Hz. All affected family members wear hearing aids or have undergone cochlear implantation. Exome sequencing and linkage and association analyses identified a fully penetrant sequence variant (rs35725509) on chromosome 12q21 (logarithm of odds, 3.3) in the TMTC2 gene region that segregates with SNHL in this family. This gene explains the SNHL occurrence in this family. The variant is also associated with SNHL in a cohort of 363 unrelated individuals (179 patients with confirmed SNHL and 184 controls, P = 7 × 10-4).Conclusions and relevanceA previously uncharacterized gene, TMTC2, has been identified as a candidate for causing progressive SNHL in humans. This finding identifies a novel locus that causes autosomal dominant SNHL and therefore a more detailed understanding of the genetic basis of SNHL. Because TMTC2 has not been previously reported to regulate auditory function, the discovery reveals a potentially new, uncharacterized mechanism of hearing loss.

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:ImportanceSudden sensorineural hearing loss (SSHL) accompanied by vertigo may portend a negative prognosis in the hearing outcome.ObjectiveTo investigate the association of vertigo with prognosis of hearing variables in SSHL.Data sourcesA literature search of eligible studies was performed in PubMed, Web of Science, and Embase from September 26, 1973, through September 26, 2017. Studies published in English were retrieved with no restrictions on the date of publication. References were identified by screening the proceedings of relevant reviews, and annual meeting and other correlative papers were scanned manually for enrollment.Study selectionAll original research studies and retrospective or prospective studies focusing on the role of vertigo in the prognosis for the hearing outcome of SSHL were systematically retrieved. Studies that did not include data regarding the association between the rate of hearing recovery and vertigo were excluded, as were reviews, comments, case reports, editorials, letters, and practice guidelines.Data extraction and synthesisData were extracted and evaluated by 2 researchers. Data extracted included research type, number of participants with or without vertigo, treatment regime, definition of pure-tone average, criteria for hearing improvement, and length of follow-up. The quality of included studies was evaluated using the Newcastle-Ottawa Scale (scores range from 0-9, with a score of ≥6 indicating a high-quality study). The data were synthesized in Mantel-Haenszel models; the aggregate results were estimated in forest plots.Main outcomes and measuresAssociation of vertigo with the prognosis for the hearing outcome of SSHL.ResultsOf the 4814 unique patients identified in 10 studies, 1709 were included in the SSHL group with vertigo and 3105 were included in SSHL group without vertigo. The Newcastle-Ottawa Scale score of each study selected was greater than 7. The recovery rate of hearing was 42.13% in the group with vertigo, compared with 60.29% in the group without vertigo. Vertigo was significantly associated with a worse hearing recovery (odds ratio, 2.22; 95% CI, 1.54-3.20; I2 = 74%). Similar results were obtained in subgroup analyses of the grading system using the Siegel criteria and systemic corticosteroid therapy. However, no association of vertigo with the prognosis of SSHL was observed within the subgroup receiving intratympanic corticosteroids (odds ratio, 1.78; 95% CI, 0.64-4.94; I2 = 70%).Conclusions and relevanceCurrent evidence revealed that vertigo may be negatively associated with hearing recovery in patients with SSHL, except in a subgroup that received intratympanic corticosteroids. Corticosteroid injection may be more effective for treatment of SSHL accompanied by vertigo; future studies are needed to determine whether treatment of vertigo might contribute to the recovery of SSHL.

Project description:Atherosclerosis is reported to be a risk factor for the severity of idiopathic sudden sensorineural hearing loss (ISSNHL). We evaluated the hypothesis that atherosclerosis affects the hearing thresholds of both the affected and healthy sides of ISSNHL patients. We conducted multivariate analyses on retrospectively collected data of patients with ISSNHL (N = 762) to evaluate the relationship between known factors linked to atherosclerosis and hearing thresholds on affected and healthy sides and whether these factors are prognostic for hearing recovery. Older ages, vertigo or dizziness, diabetes mellitus, and congestive heart failure were significantly related to higher hearing thresholds on the affected side. Older ages, male, and vascular disease were significantly related to higher hearing thresholds on the healthy side. Vertigo or dizziness, severe hearing loss and hearing loss at high frequencies on the affected side, higher hearing thresholds on the healthy side, regular anticoagulant medication, and delayed steroid treatment were significantly related to lack of recovery. Since several atherosclerosis-related factors are associated with higher hearing thresholds on both affected and healthy sides in ISSNHL and higher hearing thresholds on the healthy side predict poorer prognosis, diagnosis, and predicting prognosis of ISSNHL may benefit from rigorous evaluation of patients' cardiovascular comorbidities and hearing levels on both the healthy and affected sides.

Project description:BackgroundWhile the etiology of sudden sensorineural hearing loss (SSNHL) remains unclear, viral infection has been suggested as a possible cause. Human papillomavirus (HPV) might trigger immune-mediated reaction and induce inflammatory cytokines which are injurious to the cochlea. This study aimed to investigate the association between HPV infection and the risk of developing SSNHL using a nationwide population-based data set.MethodsIn this study, we used the population-based National Health Insurance Research Database of Taiwan to enroll 49,247 individuals with HPV infection from January 1st, 2000, to December 31st, 2013, and compared with a control group of 98,494 individuals who had never been diagnosed with HPV infection (at a 1:2 ratio matched by age, sex, index year, and comorbidities) in relation to the risk of subsequent SSNHL. The primary outcome was the time from the index date to the date when the first diagnosis of SSNHL occurred, death, withdrawal from the National Health Insurance Program, or the end of the study. Cox model with frailty was conducted to estimate hazard ratios (HRs) and 95% confidence intervals (CIs), relative to comparison group. Sensitivity analyses were performed to validate our findings.FindingsThe adjusted hazard ratio (aHR) of developing SSNHL was 1.37 (95% CI, 1.07-1.74) after adjustment for demographic characteristics, comorbidities, and medications. Sensitivity analyses showed consistent positive association. In our sub-group analysis, a significantly higher effect of HPV on SSNHL was noted in the patients with a previous diagnosis of cerebrovascular disease, compared with those without cerebrovascular disease (aHR: 4.59 versus 1.27, p-value for interaction = 0.024).InterpretationHPV infections are associated with higher risk of subsequent SSNHL in the Taiwanese population. More research is needed to examine the causality and to determine the potential efficacy of specific precautions.FundingThis research received no specific grant from any funding agency in the public, commercial, or not-for-profit sectors.
