Objective:To explore the clinical characteristics, audiological outcomes, and factors influencing the efficacy of pharmacological treatment in patients with sudden hearing loss associated with large vestibular aqueduct syndrome(LVAS). Methods:A retrospective analysis was conducted on the clinical data of 77 bilateral LVAS patients(117 ears) hospitalized for sudden hearing loss from January 1, 2009, to December 31, 2023. The inclusion criteria required that patients to be diagnosed according to the Valvassori standard and had received standardized pharmacological treatment. Clinical features, audiological outcomes, and treatment efficacy were analyzed. Statistical methods were employed to identify factors associated with treatment outcomes. Results:The age of the enrolled patients ranged from 4 to 37 years. The age of onset for the initial hearing fluctuation varied between 0 and 24 years, with a mean age of 5.8 years. The male-to-female ratio was approximately balanced(37 males and 40 females). The proportion of unilateral to bilateral sudden hearing loss was 1.0︰1.2, with unilateral right ear hearing loss being more frequently occurring(64.9%). Triggering Factors: Triggers included no identifiable factors in 48.1% of cases, a history of head trauma(24.7%), upper respiratory tract infections(11.7%), onset following physical fatigue(11.7%), and less frequently, noise exposure, alcohol consumption, or emotional stress(each 1.3%). Clinical Symptoms: Hearing loss was the sole symptom in 35.1% of cases. Concurrent symptoms included vertigo in 44.2% and tinnitus in 46.8%. Patients with a disease duration of ≤14 days demonstrated a treatment efficacy rate of 75.0%. Among those who responded to treatment, 93.0% had profound or greater hearing loss prior to therapy, with an average improvement in hearing thresholds of 32 dB HL. In pretreatment, 68.9% of patients exhibited low-frequency air-bone gaps, increasing to 76.1% post-treatment. Additionally, 17.6% of treated ears demonstrated a ≥15 dB HL improvement in low-frequency bone conduction thresholds. In the non-responsive group, 7.3% of ears still showed some improvement in bone conduction thresholds. Statistically significant differences(P<0.05) were observed between the treatment-effective and non-effective groups concerning the age of initial hearing fluctuation, disease duration, and severity of hearing loss at onset. Conclusion:The efficacy of pharmacological treatment for sudden hearing loss in LVAS patients is influenced by the age at onset, duration of the disease, and severity of hearing impairment. Early diagnosis and timely intervention significantly enhance treatment efficacy, particularly in patients with a disease duration of ≤14 days and an initial sudden hearing loss. Patients with severe hearing loss, especially those with profound or greater impairment, exhibit greater sensitivity to treatment. Pharmacological interventions positively impact both air conduction and bone conduction thresholds, with the observed improvement in bone conduction thresholds warranting further investigation.

Hyperlipidemia is characterized by elevated levels of blood lipids. The clinical manifestations are mainly atherosclerosis caused by the deposition of lipids in the vascular endothelium. The link between abnormal lipid metabolism and sudden hearing loss remains unclear. This article presents a case study of sudden hearing loss accompanied by familial hyperlipidemia. Pure tone audiometry indicated intermediate frequency hearing loss in one ear. Laboratory tests showed abnormal lipid metabolism, and genetic examination identified a heterozygous mutation in theAPOA5 gene. Diagnosis: Sudden hearing loss; hypercholesterolemia. The patient responded well to pharmacological treatment. This paper aims to analyze and discuss thepotential connection between abnormal lipid metabolism and sudden hearing loss.

Objective:To analyze the genetic counseling characteristics and interpretation of pathogenic variants for mitochondrial hearing loss.Methods:We analyzed a total of 513 unrelated families from Chinese Deafness Genome Project (CDGP), in which previous gene testing had found no pathogenic mutations with hearing loss (HL) related to the nuclear genes. We used targeted testing and complete mtDNA sequencing for the families′ available members.Results:Among the first individuals of the families to be tested, 20 cases (16 probands and 4 normal hearing consultants) were discovered with variants in mtDNA, including m.1095T>C, m.1310C>T, m.1494C>T and m.1555A>G in MT-RNR1, m.7445A>G, m.7505T>C, m.7510T>C and m.7511T>C in MT-TS1, and m.3243A>G in MT-TL1. We identified MT-RNR1 and MT-TS1 variants occurred as homoplasmic changes, while MT-TL1 variants occurred as heteroplasmic changes. Most mitochondrial hearing loss were characterized by slope or flat moderate to profound sensorineural HL. HL associated with the mtDNA pathogenic variant was variable onset age, severity and audiometric configuration. The penetrance for HL in individuals with the m.1095T>C variant might be low. Progression in the severity of HL was caused by the m.7445A>G pathogenic variant and the patients with m.7505T>C had cookie bite HL. MT-TL1 m.3243A>G was a common spot for pathogenic variants associated with nonsyndromic HL as well as syndromic HL with diabetes mellitus. Conclusions:Individuals with the mtDNA variants and their maternal relatives have a higher risk of HL and phenotypic heterogeneity in the age of onset, progression, and level of HL. The medical history should include review of any audiological testing of the probands and their family members on a maternal mtDNA background. The process of genetic evaluation needs rule out nuclear gene mutations and analyzes the genetic load of mitochondrial pathogenic variants in the probands or consultants. In these cases, we rely on clinical and genetic evaluation molecular analysis to appropriately counsel families for whom an exact cause of HL and to help them make informed medical decisions.

Postzygotic mutations are acquired in normal tissues throughout an individual's lifetime and hold clues for identifying mutagenic factors.Here,we investigated postzygotic mutation spectra of healthy individuals using optimized ultra-deep exome sequencing of the time-series samples from the same volunteer as well as the samples from different individuals.In blood,sperm,and muscle cells,we resolved three common types of mutational signatures.Signatures A and B represent clock-like mutational processes,and the polymorphisms of epigenetic regulation genes influence the pro-portion of signature B in mutation profiles.Notably,signature C,characterized by C>T transitions at GpCpN sites,tends to be a feature of diverse normal tissues.Mutations of this type are likely to occur early during embryonic development,supported by their relatively high allelic frequencies,presence in multiple tissues,and decrease in occurrence with age.Almost none of the public datasets for tumors feature this signature,except for 19.6%of samples of clear cell renal cell carcinoma with increased activation of the hypoxia-inducible factor 1(HIF-1)signaling pathway.Moreover,the accumulation of signature C in the mutation profile was accelerated in a human embryonic stem cell line with drug-induced activation of HIF-1α.Thus,embryonic hypoxia may explain this novel signature across multiple normal tissues.Our study suggests that hypoxic condition in an early stage of embryonic development is a crucial factor inducing C>T transitions at GpCpN sites;and indi-viduals'genetic background may also influence their postzygotic mutation profiles.
