Abstract
BACKGROUND This study aimed to provide an updated prevalence of hearing loss, tinnitus, vertigo and sudden deafness on patients with Sjögren's syndrome and matched comparison patients. METHODS Data for this study were retrieved from the Taiwan Longitudinal Health Insurance Database and Taiwan's registered catastrophic illness dataset. This study included 20 266 patients with Sjögren's syndrome as the study group and 60 798 propensity score-matched comparison patients as the comparison group. We used multivariable logistic regressions to estimate the ORs and 95% CI for tinnitus, hearing loss, vertigo and sudden deafness among Sjögren's syndrome patients versus comparison patients. RESULTS χ2 tests showed there were statistically significant differences between the study group and comparison group in the prevalence of tinnitus (10.1% vs 6.3%, p<0.001), hearing loss (5.6% vs 3.3%, p<0.001), vertigo (4.6% vs 3.2%, p<0.001) and sudden deafness (0.8% vs 0.6%, p<0.001). Multiple logistic regression revealed that patients with Sjögren's syndrome had a greater tendency to have tinnitus (OR=1.690, 95% CI 1.596-1.788), sudden deafness (OR=1.368, 95% CI 1.137-1.647), hearing loss (OR=1.724, 95% CI 1.598-1.859) and vertigo (OR=1.473, 95% CI 1.360-1.597) relative to comparison patients after adjusting for age, income, geographic location, residential urbanisation level, diabetes, hypertension, hyperlipidaemia and rheumatoid arthritis. CONCLUSIONS We found higher prevalence of hearing loss, vertigo, tinnitus and sudden deafness among patients with Sjögren's syndrome relative to comparison patients. Findings may provide guidance to physicians in counselling patients with Sjögren's syndrome regarding a higher risk of hearing loss, tinnitus, sudden deafness and vertigo.

Abstract
The stria vascularis (SV) has been shown to play a critical role in the pathogenesis of many diseases associated with sensorineural hearing loss (SNHL), including age-related hearing loss (ARHL), noise-induced hearing loss (NIHL), hereditary hearing loss (HHL), and drug-induced hearing loss (DIHL), among others. There are a number of other disorders of hearing loss that may be relatively neglected due to being underrecognized, poorly understood, lacking robust diagnostic criteria or effective treatments. A few examples of these diseases include autoimmune inner ear disease (AIED) and/or autoinflammatory inner ear disease (AID), Meniere's disease (MD), sudden sensorineural hearing loss (SSNHL), and cytomegalovirus (CMV)-related hearing loss (CRHL). Although these diseases may often differ in etiology, there have been recent studies that support the involvement of the SV in the pathogenesis of many of these disorders. We strive to highlight a few prominent examples of these frequently neglected otologic diseases and illustrate the relevance of understanding SV composition, structure and function with regards to these disease processes. In this study, we review the physiology of the SV, lay out the importance of these neglected otologic diseases, highlight the current literature regarding the role of the SV in these disorders, and discuss the current strategies, both approved and investigational, for management of these disorders.

Abstract
Abstract
Objective
This study aimed to evaluate primary Sjögren's syndrome patients in terms of hearing and vestibular functions.
Methods
The patient group consisted of 35 individuals diagnosed with primary Sjögren's syndrome and a control group of 35 healthy individuals similar in terms of age and gender.
Results
The rate of hearing loss in the patient group was significantly higher than in the control group (p = 0.021). The N1 latency value for the ocular vestibular-evoked myogenic potentials test was significantly longer in the patient group than in the control group (p = 0.037). Additionally, the posterior semicircular canal and lateral semicircular canal vestibulo-ocular reflex gain values were significantly lower than in the control group (p = 0.022 and p < 0.001, respectively).
Conclusion
These results indicate subclinical vestibular involvement and hearing loss in primary Sjögren's syndrome patients. Vestibular-evoked myogenic potentials and video head impulse tests can be used to detect vestibular involvement in primary Sjögren's syndrome patients.

Abstract
PURPOSE OF REVIEW This article reviews the current literature regarding the pathogenesis of immune-mediated sensorineural hearing loss, utilizes previously published single-nucleus transcriptional profiles to characterize cytokine and cytokine receptor expression in the adult stria vascularis cell types to support immune system interaction with the stria vascularis and reviews the current literature on immunomodulatory agents currently being used for hearing-restoration treatment. RECENT FINDINGS The literature review highlights recent studies that elucidate many cytokines and immune markers, which have been linked to various immune-mediated disease processes that have been observed with sensorineural hearing loss within the stria vascularis and highlights recent publications studying therapeutic targets for these pathways. SUMMARY This review highlights the current literature regarding the pathogenesis of immune-mediated hearing loss. The role of cochlear structures in human temporal bones from patients with immune-mediated sensorineural hearing loss are highlighted, and we review cytokine signalling pathways relevant to immune-mediated sensorineural hearing loss and localize genes encoding both cytokine and cytokine receptors involved in these pathways. Finally, we review immunomodulatory therapeutics in light of these findings and point to opportunities for the application of novel therapeutics by targeting these signalling pathways.

Abstract
INTRODUCTION Autoimmune Inner Ear Disease (AIED) can be of a primary or secondary type. To date, a clear pathogenesis of the disease is still not available. Focusing on the secondary forms of AIED, the aim of this review is to (i) assess and describe the hearing involvement in patients affected by autoimmune diseases, (ii) describe the possible association between clinical features (among serological/laboratory data and disease activity/duration) and hearing impairment, (iii) show evidence connecting the AIED types with various etiopathogenetic mechanisms. AREAS COVERED A PRISMA-compliant systematic review was performed. Medline, Cochrane, Embase, and Cinahl were searched from 1 January 2015 through to 5 August 2020. Overall, 16 studies (involving 1043 participants) were included in the review. The data in the literature suggested that bilateral mild-to-moderate sensorineural hearing loss is a commonly reported clinical symptom of AIED. EXPERT OPINION Patients with systemic autoimmune disorders present a cochlear injury which might be associated with the humoral and/or cellular immune response against the inner ear. To date, AIED pathogenesis remains an open issue, due to the rarity of these clinical entities and due to the difficulties in investigating the inner ear immunology, considering the inner ear inaccessibility for tissue sampling.

Abstract
Symptoms of dry eyes or dry mouth, otherwise known as sicca symptoms, are not always present in patients with Sjögren's syndrome (SS). Approximately 20% of patients with SS do not have sicca symptoms. An unusual case of a patient presenting with complete left-sided facial hemiparesis, a history of partial bilateral sensorineural hearing loss who was found to have elevated antinuclear antibody (ANA) with high titer positive SSA/Ro antibody, evidence of bilateral parotitis on imaging and absence of sicca symptoms, prompted us to perform a literature review. Twelve case reports relating facial nerve palsy and Sjögren's were found and only one described a similar constellation of features of unilateral facial weakness and otalgia. Management of facial nerve palsy related to Sjögren's is unclear but pharmacological agents have included corticosteroids, intravenous immune globulin (IVIG), cyclophosphamide, and plasmapheresis. This case report describes a patient whose facial nerve palsy is attributed to SS, explores peripheral and central nervous system involvement in SS, and provides some recommended treatments.

Abstract
The stria vascularis (SV) generates the endocochlear potential (EP) in the inner ear and is necessary for proper hair cell mechanotransduction and hearing. While channels belonging to SV cell types are known to play crucial roles in EP generation, relatively little is known about gene regulatory networks that underlie the ability of the SV to generate and maintain the EP. Using single cell and single nucleus RNA-sequencing, we identify and validate known and rare cell populations in the SV. Furthermore, we establish a basis for understanding molecular mechanisms underlying SV function by identifying potential gene regulatory networks as well as druggable gene targets. Finally, we associate known deafness genes with adult SV cell types. This work establishes a basis for dissecting the genetic mechanisms underlying the role of the SV in hearing and will serve as a basis for designing therapeutic approaches to hearing loss related to SV dysfunction.

Abstract
The triad of central nervous system symptoms, visual disturbance and hearing impairment is an oft-encountered clinical scenario. A number of immune-mediated diseases should be considered among the differential diagnoses including: Susac syndrome, Cogan syndrome or Vogt-Koyanagi-Harada disease; demyelinating conditions such as multiple sclerosis or neuromyelitis optica spectrum disorder; systemic diseases such as systemic lupus erythematosus, Sjögren syndrome or Behcet disease and granulomatous diseases such as sarcoidosis. In this article, we coin the term 'BEE syndromes' to draw attention to the various immune-mediated diseases that affect the brain, eye and ear. We present common disease manifestations and identify key clinical and investigation features.

Abstract
Sjögren’s syndrome (SS) is a systemic autoimmune disease characterized by lymphocytic infiltration of exocrine glands and a range of extra-glandular features. The most common and earliest symptoms are oral and ocular dryness. The aim of this study is to present the most common otolaryngological manifestations of SS, their pathomechanism and possible aetiology. The most common oral signs and symptoms are xerostomia, tooth decay, fungal infections, traumatic oral lesions, dysphagia, dysgeusia, and inflammation of the salivary glands. The salivary glands of SS patients are characterised by chronic inflammation. The presence of foci is thus a hallmark of SS. A biopsy can be taken from either the labial or the parotid salivary gland. The most significant complication of SS is the development of lymphoproliferative malignancy, which occurs in about 5% of SS patients. The ultrasonic greyscale scoring system, glandular volume measurement, and intraglandular power Doppler ultrasonography are specific ultrasound parameters of SS.

Abstract
Objective AIED (autoimmune inner ear disease) is an autoimmune process that leads to the dysfunction of the inner ear, resulting in fluctuating, audiovestibular symptoms. Although the pathogenesis is likely heterogeneous, immune processes within the inner ear ultimately lead to histopathologic changes and sensorineural hearing loss. This review will discuss the latest evidence on treatment options. Methods A literature search on articles pertaining to the treatment of autoimmune inner ear disease was performed on PubMed. Results Corticosteroid treatment continues to remain as first line therapy for AIED but long-term responsiveness is poor. Cytotoxic chemotherapies can be effective alternatives for steroid nonresponsive patients, but significant side effects may limit their use. Intratympanic steroid injections are beneficial and although there is not enough evidence currently to supplant oral steroid trial they may be a useful adjunct if steroid toxicity is an issue. The efficacy of biologic agents has been variable. Compared to placebo, etanercept does not improve the hearing improvement already attained by steroids alone. However, open pilot studies of other biologic agents show hearing improvements, improvements in tinnitus/aural fullness/vertigo, ability to wean steroid dependency, or benefits in steroid-resistant AIED. Conclusion There is currently not enough evidence that alternative treatments supersede the use of initial steroid treatment. Biologic agents and intratympanic steroid injections are relatively well tolerated and should be considered as adjunctive therapy. More studies on the efficacy of various biologics and more studies on the treatment of steroid resistant disease especially after initial benefit are still needed. For those who eventually lose their hearing, cochlear implantation remains as a viable option. Level of Evidence expert opinion.

Abstract
The ultrastructural organization of the blood labyrinthine barrier (BLB) was investigated in the human vestibular endorgan, the utricular macula, using postmortem specimens from individuals with documented normal auditory and vestibular function and surgical specimens from patients with intractable Meniere’s disease. Transmission electron microscopic analysis of capillaries located in the normal human utricular stroma showed vascular endothelial cells with few pinocytotic vesicles, covered by a smooth and uniform basement membrane surrounded by pericyte processes. Meniere’s disease specimens revealed differential ultrastructural pathological changes in the cellular elements of the microvasculature. With moderate degeneration of the BLB, there were numerous vesicles within the vascular endothelial cells (VECs), with increased numbers at the abluminal face, pericyte process detachment and disruption of the perivascular basement membrane surrounding the VECs. With severe degeneration of the BLB, there was severe vacuolization or frank apparent necrosis of VECs and loss of subcellular organelles. A higher severity of BLB degenerative changes was associated with a higher degree of basement membrane thickening and edematous changes within the vestibular stroma. This study presents the first ultrastructural analysis of the capillaries constituting the BLB in the human vestibular macula utricle from normal and Meniere’s disease.

Abstract
In this review, we provide a description of the recent methods used for immunohistochemical staining of the human inner ear using formalin-fixed frozen, paraffin and celloidin-embedded sections. We also show the application of these immunohistochemical methods in auditory and vestibular endorgans microdissected from the human temporal bone. We compare the advantages and disadvantages of immunohistochemistry (IHC) in the different types of embedding media. IHC in frozen and paraffin-embedded sections yields a robust immunoreactive signal. Both frozen and paraffin sections would be the best alternative in the case where celloidin-embedding technique is not available. IHC in whole endorgans yields excellent results and can be used when desiring to detect regional variations of protein expression in the sensory epithelia. One advantage of microdissection is that the tissue is processed immediately and IHC can be made within 1 week of temporal bone collection. A second advantage of microdissection is the excellent preservation of both morphology and antigenicity. Using celloidin-embedded inner ear sections, we were able to detect several antigens by IHC and immunofluorescence using antigen retrieval methods. These techniques, previously applied only in animal models, allow for the study of numerous important proteins expressed in the human temporal bone potentially opening up a new field for future human inner ear research.
