Abstract
Kabuki Syndrome (KS) is a multisystemic genetic disorder. A portion of patients has immunological manifestations characterized by increased susceptibility to infections and autoimmunity. Aiming to describe the clinical and laboratory immunological aspects of KS, we conducted a retrospective multicenter observational study on patients with KS treated in centers affiliated to the Italian Primary Immunodeficiency Network.Thirty-nine patients were enrolled, with a median age at evaluation of 10 years (range: 3 m-21y). All individuals had organ malformations of variable severity. Congenital heart defect (CHD) was present in 19/39 patients (49%) and required surgical correction in 9/39 (23%), with associated thymectomy in 7/39 (18%). Autoimmune cytopenia occurred in 6/39 patients (15%) and was significantly correlated with thymectomy (p < 0.002), but not CHD. Individuals with cytopenia treated with mycophenolate as long-term immunomodulatory treatment (n = 4) showed complete response. Increased susceptibility to infections was observed in 22/32 patients (69%). IgG, IgA, and IgM were low in 13/29 (45%), 13/30 (43%) and 4/29 (14%) patients, respectively. Immunoglobulin substitution was required in three patients. Lymphocyte subsets were normal in all patients except for reduced naïve T-cells in 3/15 patients (20%) and reduced memory switched B-cells in 3/17 patients (18%). Elevated CD3 + TCRαβ + CD4-CD8-T-cells were present in 5/17 individuals (23%) and were correlated with hematological and overall autoimmunity (p < 0.05).In conclusion, immunological manifestations of KS in our cohort include susceptibility to infections, antibody deficiency, and autoimmunity. Autoimmune cytopenia is correlated with thymectomy and elevated CD3 + TCRαβ + CD4-CD8-T-cells, and benefits from treatment with mycophenolate.

Abstract
The role of the immune system in mediating cochleovestibular pathologies has received increasing attention in recent years. Autoimmune vertigo may be an invalidating condition and may worsen the quality of life of affected patients, especially in the cases of delayed diagnosis. Since the etiopathogenesis is still not clear, also the treatment is not yet completely delineated. According to the clinical presentation, autoimmune vertigo can present as an isolated disorder or in association with systemic autoimmune diseases. The main feature in autoimmune vertigo is the presence of an abnormal immune response, in either absence or presence of systemic autoimmune disease, directed against delicate components of the inner ear. This may determine a functional or anatomical alteration, with an inflammatory reaction often devastating for hearing and balance. Being the exact pathogenesis unknown, the diagnosis of autoimmune vertigo is based either on clinical criteria or on a positive response to steroids. The earlier the diagnosis is made, the sooner the therapy can be installed, giving a chance to the recovery of inner ear damages. Corticosteroids represent the most effective and universally accepted treatment, even if other immunomodulatory drugs are now having a more extensive use. HIGHLIGHTS: Vertigo is relatively frequent in autoimmune diseases; however, it is often misdiagnosed or attributed to central nervous system alterations rather to specific inner ear involvement. Vertigo and other audiovestibular symptoms may be the first manifestation of an autoimmune disease and if correctly addressed could significantly contribute to early diagnosis of the underlying autoimmune disease. Early diagnosis of immune-related vertigo can lead to prompt initiation of targeted therapy with elevate chances of preventing irreversible damages to the inner ear. The presence of alternating phases of well-being and disabling symptoms in patients with vertigo should always been considered, as they could suggest an underlying autoimmune condition.

Abstract
Diabetes mellitus is the most common endocrine disease, characterized by chronic hyperglycemia. The hyperglycemic milieu leads to endothelial injury in blood vessels of variant size, which results in microangiopathy and macroangiopathy (atherosclerosis). Consequential ischemia of nerves and hyperglycemia by itself lead to nerve degeneration and generalized neuropathy, affecting most often the sensory peripheral nerves and the autonomic nervous system. Auditory, vestibular and olfactory sensorium may be compromised by DM. People with DM have an increased susceptibility to infection, as a result of neutrophil dysfunction and impaired humoral immunity. Therefore DM predisposes to certain infectious diseases, such as fungal sinusitis or malignant otitis externa, which are rare in general population. Recovery from infections or from injuries may be compromised by coexisting DM. In this review we discuss complications of DM in the head and neck region. Otolaryngologists and general practitioners should be alert to specific conditions related to DM and be minded of the relevant complications and consequences.

Abstract
PURPOSE OF REVIEW Immune-mediated inner-ear disorders may present to different medical disciplines and new research findings emerge rapidly. The purpose of this review is to draw the different strands together to produce an overview describing the clinical presentation of immune-mediated inner-ear disorders and to discuss useful diagnostic criteria with a focus on tissue-specific and tissue-non-specific antibodies. RECENT FINDINGS The importance of diagnosing an immune-mediated inner-ear disorder is highlighted in the context of it being one of few forms of treatable inner-ear disorder with a good response to immunosuppressive therapy. Due to a lack of reliable tests, the criteria upon which the diagnosis of immune-mediated inner-ear disease is based are often arbitrary. Previous and current research focuses mainly on the investigation of the aetiology of immune-mediated disorders, studying the presence of autoantibodies and the antigens responsible for their production. The prognostic and therapeutic values of inner-ear-specific antibodies are still unclear. Various antigens have been suggested. However, most antigens identified have been ubiquitous proteins not specific to the inner ear and therefore lack logical association with localized inner-ear pathology. SUMMARY Early diagnosis of immune-mediated inner-ear disorders with prompt treatment may prevent irreversible damage to inner-ear structures. Accordingly, it is important to include immune-mediated inner-ear disorders in the differential diagnosis of patients presenting with 'idiopathic' audiovestibular dysfunction. To enable early diagnosis, we recommend that the current available routine immunological laboratory tests (antinuclear, antineutrophil cytoplasmic, antiendothelial cell, antiphospholipid/anticardiolipin and antithyroid antibodies) are used when assessing a patient with suspected immune-mediated inner-ear disorder.

Abstract
CONCLUSIONS Although vestibular recovery was observed after steroid treatment, it remains uncertain whether this improvement was spontaneous or due to medication. These data do not allow us to generally recommend corticosteroid treatment in patients with BVF and inner ear antibodies. OBJECTIVE A retrospective study was performed based on the observation of two patients with suspected autoimmune bilateral vestibular failure (BVF) with normal hearing and antilabyrinthine or nervous tissue-specific serum antibodies who showed vestibular recovery after corticosteroid treatment. MATERIAL AND METHODS Twelve patients with BVF and serum inner ear antibodies who had received imuunosuppressive treatment with corticosteroids were evaluated in terms of medical history, repetitive caloric irrigation and repetitive determination of inner ear antibodies. BVF was complete in four patients and incomplete in eight. RESULTS After immunosuppressive therapy, four of the 12 patients showed a moderate recovery of the peak slow-phase velocity of horizontal nystagmus induced by bithermal caloric stimulation, which was only transient in two of them.

Abstract
INTRODUCTION Antiphospholipid antibodies lupus anticoagulant (LA) and anticardiolipin antibodies (aCL) play a role in promoting arterial and venous thrombosis in several vascular territories. Acute vestibular syndromes are a common complaint in general and neurology practice. Approximately 9% of cases are due to central nervous system vestibular areas lesions, often associated with vascular disorders. OBJECTIVE Define the potential relationship between these antibodies and central or peripheral vestibular failure. PATIENTS AND METHODS We report the presence of antiphospholipid antibodies in 16 patients with central vestibular symptoms. All patients were seen in the Neuro otology and Vascular Neurology clinics at the Institute for Neurological Research in Buenos Aires. Magnetic resonance imaging (MRI) and ancillary neuro otologic tests were used to determine the etiology of vestibular manifestations. Determinations of LA and aCL were done using standard criteria. RESULTS We evaluated 16 patients (13 women and 3 men), aged 44 4 years (21 65). Thirteen patients did not have stroke risk factors. MRI lesions were found in 11 subjects (1 cerebellar infarct, 3 pontine ischemic changes, and 9 white matter abnormalities). All patients had signs consistent with dysfunction of vestibulo cerebellar structures or the vestibular nuclei. All patients had positive LA and 4 of them had also elevated aCL. CONCLUSION Our findings suggest a potential association between the presence of a prothrombotic state and central vestibular dysfunction of vascular etiology. To the best of our knowledge, this is the first report of such an association in the absence of clinically evident autoimmune disease.

Abstract
The present study investigated vestibulo-ocular reflex (VOR), optokinetic reflex (OKR) and postural function in patients with rheumatoid arthritis (RA). Compared with controls, no differences in gaze-holding, VOR gain or phase, OKR slow phase velocity (SPV) or quick phase amplitude, optokinetic afternystagmus SPV or duration, or latency to the illusion of circularvection, were found. RA patients did exhibit greater sway in the leftward direction (P<0.01), however, this was no greater in the conditions of the Clinical Test of Sensory Interaction and Balance that increase reliance upon vestibular information. We conclude that RA patients do not exhibit substantial deficits in visual-vestibular function.

Abstract
This study was undertaken to examine the expression of inducible nitric oxide synthase (iNOS / NOS II) in the hydropic vestibule of guinea pigs. Animals were systemically sensitized with 500 microg of keyhole limpet hemocyanin. Two weeks after the first injection, keyhole limpet hemocyanin (100 microg/5 microl) was injected into the endolymphatic sac following the intradural approach, and the next day temporal bones were removed for the immunohistochemical examination. Endolymphatic hydrops was evidenced by the expansion of the Reissner's membrane in the cochlea after direct injection of keyhole limpet hemocyanin into the endolymphatic sac. Inducible nitric oxide synthase expression was increased in the sensory cells, supporting cells and vestibular ganglion cells, while temporal bones, where only phosphate buffered saline was injected, did not show any inducible nitric oxide synthase immunoreactivity. High levels of inducible nitric oxide synthase-catalyzed nitric oxide were detected prior to the development of the inner ear dysfunction. Our results suggest that the occurrence of inducible nitric oxide synthase immunoreactivity parallels the inner ear disturbance as seen in endolymphatic hydrops.

Abstract
OBJECTIVE Immune-mediated cochleovestibular disorders (IMCVDs) continue to present a management challenge to the otolaryngologist. Antirheumatic agents, commonly used for IMCVDs, are associated with variable efficacy and sometimes with serious side effects. The authors describe the preliminary result of their experience in patients with IMCVDs who have been treated with etanercept, a tumor necrosis factor alpha receptor blocker, recently approved by the United States Food and Drug Administration for the treatment of rheumatoid arthritis. STUDY DESIGN Retrospective case series. SETTING Tertiary care hospital. PATIENTS Twelve patients suspected of having IMCVD who did not respond to conventional therapies or experienced side effects of the conventional therapies. INTERVENTION Etanercept 25 mg by subcutaneous injection twice per week. MAIN OUTCOME MEASURES The main outcome measurement was assessment of hearing change by air conduction pure tone audiograms and/or word discrimination. When present, vertigo, tinnitus, and aural fullness were assessed as well. RESULTS Follow-up of more than 5 months was available for all patients (range, 5-12 months). Eleven (92%) of 12 patients had improvement or stabilization of hearing and tinnitus, seven (88%) of eight patients who had vertigo and eight (89%) of nine patients who had aural fullness had resolution or significant improvement of their symptoms. The benefit persisted until the last visit (5-12 months after etanercept was begun). The condition of one patient improved dramatically at first but deteriorated after 5 months. The patient's hearing was rescued and stabilized with the addition of leflunomide to etanercept. Similarly, three other patients required a second antirheumatic agent to stabilize their hearing. There were no significant side effects from the etanercept therapy. CONCLUSIONS Our limited data suggest that etanercept therapy is safe and may be efficacious in carefully selected patients with IMCVDs, at least on a short-term basis. These preliminary efficacy and safety results appear encouraging enough to warrant further follow-up and studies for better determination of the potential clinical utility of etanercept for IMCVDs.

Abstract
The aim of this study was to evaluate the pathological significance of antibodies against cornea and inner ear tissue in the development of audiovestibular and ocular symptoms in patients with Cogan's syndrome (CS). We analysed the serum of 5 CS patients for binding of IgM and IgG to fresh cryosections of rat labyrinth (semicircular canals, ampulla, utricle, saccule) and cornea by indirect immunofluorescence (IF). The predominant pattern of anti-corneal IgM was staining of the superficial cell layer of the non-keratinizing squamous epithelium. IgM against cornea was found in 3 patients, all of whom had bilateral inflammatory eye signs at the start of the disease. However, IgM was also detected in the chronic stage of the disease when no clinical signs of eye involvement were apparent. The study includes the first follow-up examination of anti-corneal IgM and IgG antibodies during a complete episode of active CS. During the first episode of CS in 1 patient, anti-corneal IgM became detectable 1 week after the onset of interstitial keratitis and 3 weeks after the onset of audiovestibular symptoms. It increased over several weeks and then fell to very low levels. However, at no time was anti-corneal IgG found. In the course of follow-up examinations, the serum of 4 patients intermittently contained low titre IgG antibodies against inner ear labyrinthine tissue, but without any clear correlation with the active stages of CS. In addition, high-resolution MRI (HR-MRI) of the inner ear was performed in the acute and chronic stages of CS to evaluate the activity of CS. In the acute stage, HR-MRI revealed abnormal MRI signals in the vestibule, semicircular canals, vestibular nerve, or cochlea. In the chronic stage, patients showed narrowing or occlusion of semicircular canals and the cochlea on the 3D-CISS images, but no high signal lesions (T1) and no enhancement. Antibodies against cornea or labyrinthine tissue were not consistently detected in CS and the level of organ-specific antibodies did not correlate with the activity of the disease.

Abstract
Cogan's syndrome is an autoimmune disease of unknown etiology, clinically manifested as non-syphilitic interstitial keratitis and audiovestibular symptoms. Increasing evidence suggests that Cogan's may be a systemic vasculitis. In this report, we review the vascular manifestations of Cogan's syndrome and report two cases of thoracoabdominal aortic aneurysm in patients with this disorder.

Abstract
The purpose of the investigation was to ascertain whether inoculation of bacterial lipopolysaccharide (LPS) into the vestibular organ of the guinea pig might induce formation of nitric oxide synthase (NOS) II. Forty-eight hours after the animals were injected with 1 mg transtympanic LPS, varying degrees of impaired caloric responses were observed with similar degeneration of vestibular hair cells. These effects could be blocked with N-nitro-L-arginine methylester, a competitive inhibitor of NOS. Findings suggested that NOS II, which was not normally detectable in the guinea pig vestibular organ but was present following inoculation of LPS, produced the nitric oxide as the toxic factor causing cell damage. If true, LPS may represent a reproducible method for studying the vestibular pathogenesis of inner ear disease.

Abstract
In the chronic-relapsing form of Cogan's syndrome, it can be difficult to evaluate the activity of the disease. In contrast to the initial stage, routine diagnostic techniques sometimes fail to indicate progression in the chronic stage. To determine whether high-resolution magnetic resonance imaging (HR-MRI) can be used to differentiate between active and inactive stages, we examined three patients with Cogan's syndrome (one during an acute relapse, two with chronic audiovestibular deficits), all of whom had antibodies to inner ear tissue (cochlea, vestibular labyrinth). Unenhanced T1-, T2, gadolinium-enhanced T1-weighted, and three-dimensional constructive interference in steady stage (CISS) images were used. Abnormal MRI signals of the inner ear were related to the activity of the disease. The patient studied during an acute exacerbation showed abnormal MRI signals in the vestibule, semicircular canals, vestibular nerve, and cochlea, which disappeared after the relapse. These abnormalities included high signal in the membranous labyrinth, the vestibule, and cochlea, with enhancement on T1-weighted images, indicating gadolinium leakage through the abnormal labyrinthine membrane into the perilymphatic spaces. In contrast, the other two patients with chronic audiovestibular deficits but no clinical signs of an acute relapse, had narrowing or occlusion of semicircular canals of the cochlea on the 3D-CISS images, but no high signal lesions (T1) and no enhancement. We conclude that sequential gadolinium-enhanced MRI can identify the active stage of Cogan's syndrome. The combination of HR-MRI and antibodies to inner ear antigens are helpful in the diagnosis of acute, sequential, bilateral audiovestibular impairment of autoimmune origin.

Abstract
To investigate the possibility of an autoimmune mechanism in idiopathic bilateral vestibulopathy (IBV), we screened patients' sera for antibodies against inner ear structures. IgG antibodies against membranous labyrinth (ampulla, semicircular canals, saccule and utricle) were detected in 8 of 12 patients by immunofluorescence on rat inner ear cryosections. All but one serum of 22 healthy controls and the sera of 6 patients with known autoimmune disorders showed only background staining. Low-titre anti-nuclear IgM antibodies were present in three control sera and one IBV serum. High-titre anti-nuclear IgM was found in a patient with lupus erythematosus and in one with scleroderma. Anti-nuclear IgM was not organ-specific. No human serum used contained detectable anti-vascular preformed antibodies. Cross-reactivity to sections of liver, kidney, cornea, brain and skeletal muscle was absent. Double-staining for IgG and F-actin, the primary constituent of hair cell cilia, did not show predominant Ig-coating of sensory hair cells. Immunosuppressive therapy in 3 IBV patients did not improve the disorder, probably owing to irreversible loss of sensory and neural structures. These data suggest that the bulk of anti-labyrinthine autoantibodies may be an epiphenomenon, yet a small subgroup of organ-specific autoantibodies may synergize with a cellular response in the development of vestibular lesions.

Abstract
BACKGROUND Yersinia infections other than plaque are caused by Yersinia pseudotuberculosis and Yersinia enterocolitica. Food and water contamination as well as animal-to-person and person-to-person contact are common pathways of transmission. Clinical manifestations include enteritis, enterocolitis, acute appendicitis, inflammation of the terminal ileum, and mesenteric adenitis. Y. enterocolitica may cause bacteremia with subsequent septicemia predominantly in patients with underlying illnesses such as diabetes mellitus or malignancy. More frequently enteritis is followed by immunological post-infectious syndromes such as arthritis and erythema nodosum. The present case report discusses bilateral vestibular loss possibly caused by an infection with Y. enterocolitica. PATIENTS A 27-year-old caucasian woman initially presented with the otologic symptom of spinning vertigo accompanied by nausea and vomiting. RESULTS Physical exam revealed spontaneous nystagmus to the left. Bithermal caloric responses were absent. Pure tone audiometry showed a bilateral symmetric high-frequency sensorineural hearing loss. Neurologic exams did not reveal involvement of the central vestibular system. Perilymphatic fistula on the left side was excluded by tympanoscopy. Serology for rheumatoid factors and HLA B27 was negative. Lead or mercury intoxication was also excluded. In her medical history the patient reported intermittent watery diarrhea and stress dependent arthralgia that had commenced during a stay in Argentina three years ago. Serology was positive, revealing elevated titers for Y. enterocolitica type 3 (1:200) and type 9 (1:400). DISCUSSION Bilateral vestibular loss is rare. The main cause is aminoglycoside ototoxicity or meningitis. Yersina infections have not yet been described as inducing disease of the labyrinth. Present pathophysiologic knowledge of yersinia infections is described as follows: After peroral infection, gastrointestinal permeability is increased. Low-molecular-weight substances may enter the bloodstream and stimulate the formation of circulating immune complexes. These are held responsible for extraintestinal manifestations of yersinosis. Whether these circulating immune complexes and antibodies against Y. enterocolitica have an effect on the inner ear remains unclear. CONCLUSION Because the coincidence of yersiniosis and a bilateral vestibular loss with no other identified cause, a postinfectious immune response is suggested as possible pathogenic mechanism.

Abstract
HYPOTHESIS To determine the presence of antibodies against the glycosphingolipid antigen sulfated glucuronic lactosominyl paragloboside (SGLPG) in the sera of patients suspected of immune-mediated cochleovestibular disorders (IMCVD). BACKGROUND Glycospingolipids are molecules present on the surface of normal nerve cells and are considered antigenic. Previous studies have isolated these antigens in vestibular neuroepithelia, cochleovestibular nerves and endolymphatic sacs. METHODS The sera of 22 patients suspected of IMCVD were tested for antibodies against the antigen SGLPG. Thin-layer chromatography-immunostaining method was used. RESULTS Antibody titers were elevated in 63.6% of patients tested. Statistical significance (p < 0.0001) was achieved since reactivity was seen in only 7% of 43 age-matched healthy controls. CONCLUSIONS Antibodies to SGLPG antigens are present in some patients with IMCVD. Because SGLPD antigens have been previously isolated in the inner ear and the cochleovestibular nerve, these structures can potentially become targets for anti-SGLPG antibodies.

Abstract
Immune-mediated cochleovestibular disorders continue to present a management challenge to the otolaryngologist. The traditional treatment of these disorders, corticosteroids and/or cyclophosphamide (Cytoxan), has been associated with serious and occasionally life-threatening complications. In this study we report our experience in treating 25 patients with immune-mediated cochleovestibular disorders with methotrexate, a less toxic immunosuppressive agent that has been used extensively in patients with rheumatoid arthritis. Mean duration of treatment was 12.9 months, and adverse reactions were acceptable and reversible. Hearing improved in 69.6% of patients, and vestibular symptoms subsided or improved in 80% of patients. The results of this study suggest that methotrexate treatment is effective in a substantial number of patients with immune-mediated cochleovestibular disorders and has acceptable adverse reactions. A prospective, randomized study is needed to compare the efficacy of methotrexate with that of other immunosuppressive agents.

Abstract
Aggressive papillary tumors of the temporal bone, occurring sporadically or as part of von Hippel-Lindau disease, have been shown to originate within the endolymphatic sac or duct. Also implicated as a potential precursor from which some of these tumors may arise is ectopic choroid plexus epithelium. To aid in the differentiation between papillary tumors of endolymphatic sac and duct origin and those arising from choroid plexus, an immunohistochemical study using stains for transthyretin (TTR), cytokeratins, S-100 protein, epithelial membrane antigen (EMA), and glial fibrillary acidic protein (GFAP) was carried out on archival specimens of normal and neoplastic endolymphatic sac and duct and choroid plexus epithelium. Transthyretin, a marker for choroid plexus epithelium, was found to show differential expression between choroid plexus papillomas and aggressive papillary tumors of the endolymphatic sac or duct. Therefore the use of TTR in concert with other immunohistochemical stains appear to aid in the differentiation between intracranial and intratemporal papillary tumors arising from choroid plexus and endolymphatic sac or duct epithelium.

Abstract
We report here a case of Cogan's syndrome associated with systemic vasculitis as well as myeloperoxidase-specific antineutrophil cytoplasmic antibody (MPO-ANCA)-related glomerulonephritis. A 71-year-old woman with the diagnosis of aortitis syndrome and pulmonary fibrosis for 7 years, complained of vertigo and hearing impairment. A diagnosis of serous otitis media was made. Although steroid therapy was effective, the symptoms relapsed several times. Seven months after the first manifestation of aural symptoms, she developed painful red eyes bilaterally and proteinuria. On admission, perinuclear ANCA without cytoplasmic ANCA was detected by indirect immunofluorescence assay and MOP-ANCA was detected by enzyme linked immunosorbent assay using the 363 ELISA Unit. Renal biopsy showed necrotizing crescentic glomerulonephritis without immune deposits. A diagnosis of atypical Cogan's syndrome with systemic vasculitis and pulmonary fibrosis was made from the clinical and histological findings. As nephrotic syndrome progressed after admission, she was started on high-dose corticosteroid administration. Urinary protein and other symptoms, except for hearing acuity, improved in parallel with a decrease in the MPO-ANCA titer to normal values. While tapering the dose of corticosteroid, the MPO-ANCA titer increased again and dyspnea occurred. Although pulse methylpredonisolone therapy was performed, the patient died of respiratory failure complicated with sepsis. Postmortem lung biopsy showed pulmonary fibrosis and massive alveolar hemorrhage. The findings of this case study suggest that MPO-ANCA may be closely related to the pathogenesis of Cogan's syndrome.

Abstract
Twenty-one patients with unilateral sudden deafness and 16 patients with vestibular neuritis, all with typical clinical history and findings, were investigated for a possible borrelia-cause. Only one patient, a patient with vestibular neuritis, had evidence of active borreliosis in terms of high antibody-titers in CSF, increased cell count and disturbed albumin ratio. To gain more knowledge about the etiological role of Borrelia burgdorferi in patients with hearing and vestibular symptoms, it is, despite this sparse finding, motivated to perform Borrelia testing in patients from tick-frequent areas. A reliable testing includes both serum and CSF analysis.

Abstract
1. It is necessary to keep in mind that the etiology of immune-mediated SNHL involves various causes ranging from vasculitis to type II collagen-related disorders. 2. Clinical cases believed to involve sympathetic labyrinthitis are extremely rare. 3. The mechanism of occurrence of SNHL associated with autoimmune diseases should probably not be attributed to immunologic abnormalities in all cases. 4. Of the cases of SNHL associated with autoimmune diseases, only those associated with aortitis syndrome (Takayasu disease) are steroid-responsive. 5. The autoimmune SNHL described by McCabe is believed to be closely related to Cogan's syndrome. On the other hand, steroid-responsive SNHL includes three types: a systemic type associated with aortitis syndrome, a localized type not associated with any known autoimmune disease, and a syphilitic type. It is thought that sex differences and differences in such findings as the caloric response between the two disease entities is due to interracial differences in the degree of vasculitis.

Abstract
The effect of a direct antigen challenge to the endolymphatic sac on vestibular function was investigated in guinea pigs. Following keyhole limpet hemocyanin (KLH) challenge to the sac in systemically presensitized guinea pigs, caloric responses were examined in 18 animals on days 1, 7, 14, 21, and 28. Caloric responses were significantly suppressed in 13 animals by day 7; of these, 5 animals had recovered by day 14 and 8 animals had not yet recovered by day 28. The behavior of spontaneous nystagmus was examined every hour in 10 animals at intervals of 3 to 56 hours after sac challenge. Irritative spontaneous nystagmus preceding paralytic nystagmus appeared in 5 animals, for which the mean onset was 14.6 +/- 3.1 hours and the mean duration was 4.4 +/- 6.5 hours. Paralytic spontaneous nystagmus appeared in all animals, for which the mean onset time was 23.3 +/- 12.3 hours. Neither direct KLH primary challenge of the sac nor phosphate-buffered saline injection to the sac caused significant changes in the vestibular function. These results suggest that an immune response of the sac induces a vestibular disorder and may produce an attack of vertigo similar to that of Meniere's disease.

Abstract
Following direct challenge with KLH antigen primary or secondary (after systemic immunization) to the ES (endolymphatic sac) in guinea pigs, ECoG (electrocochleograms) were recorded from the round window induced by click and tone pips. The recordings were carried out on the 2nd, 7th and 21st days after local antigen challenge. There were no abnormal findings in the ECoG of the primary antigen challenged animals. On the other hand, prolongation of latencies, decrease in amplitudes of APs (compound action potentials) and increases in SP/AP ratios were observed in the 2nd day recordings of the secondary antigen challenged animals. However, all parameters of ECoG in the 7th day recordings were normal. Decreases in AP amplitudes were again found in the 21st day recordings. The ECoG findings with click and tone pip stimulation showed similar results. From these findings, in conjunction with morphological observations, it is speculated that these ECoG findings are caused by immuno-injury to the ES and cochlea, as well as the resultant endolymphatic hydrops which develops acutely and gradually subsides after secondary challenge.

Abstract
Previously the author reported the immediate development of endolymphatic hydrops (e. hydrops) following direct challenge of secondary antigen to the endolymphatic sac (ES) in guinea pigs, during the early phases of postchallenge, ranging from 1 to 5 weeks. The present study reports the results of specimens taken up to 10 weeks postchallenge, and correlation of e.hydrops to perilymph in antigen-specific antibody levels. From the present results, mechanisms of e.hydrops induced ES immune reaction are suggested as follows. 1) In the early stage of e.hydrops, an acute inflammatory reaction in the ES may produce endolymph by an increased vascular permeability of the inner ear and may impair endolymph absorption from the ES. 2) In the latter stage of e.hydrops, the moderate cellular infiltration in the ES may cause chronic impairment of endolymph absorption in the ES.

Abstract
Cogan's syndrome is a rare systemic autoimmune disease with preeminent ophthalmological and vestibulocochlear manifestations. Untreated, the disease usually results in profound deafness; eye involvement is usually self-remitting. Ten to twenty percent of patients either develop serious aortic valve disease or vasculitis or both. When given early, immunosuppressive therapy has been shown to be effective in treating all aspects of the disease. Thus, early disease recognition is of great significance. We present a patient with Cogan's syndrome and briefly discuss therapeutic implications.

Abstract
Levels of circulating immune complexes (CICs) in 59 patients with Meniere's disease and total serum immunoglobulin E (IgE) levels in a subgroup of 42 of the 59 were determined quantitatively for possible abnormalities of humoral immunity. Significant differences in average IgE levels between the 42 patients with Meniere's disease and 18 normal control subjects were not determined; however, five (11.9%) of the 42 patients were found to have obviously raised IgE levels. Elevated CIC levels were found in 19 (32.2%) of the 59 patients with Meniere's disease and in one (2.3%) of the 43 control subjects. This difference was statistically significant. The possible mechanisms of immune-mediated endolymphatic hydrops are discussed.
