Acute autoimmune sensorineural hearing loss associated with Crohn's disease

Sensorineural hearing loss and ulcerative colitis in remission

INTRODUCTION

Sensorineural hearing loss (SNHL) has been reported in association with inflammatory bowel disease (IBD). However, SNHL as an extraintestinal manifestation of IBD is frequently underreported. In the present study, we compared the prevalence and severity of SNHL among patients with IBD-ulcerative colitis (IBD-UC) in remission with controls to find out any association between SNHL and IBD-UC in remission compared to controls.

METHODS

This single-center hospital-based prospective observational study included outdoor patients with IBD-UC in remission and healthy age- and sex-matched controls. Eligible patients and healthy participants were subjected to a battery of audiological tests (otoscopy, tympanometry and pure tone audiometry [PTN]) after thorough systemic and ear, nose and throat (ENT) examination.

RESULTS

A total of 100 patients were enrolled in the study: 50 in IBD-UC in the remission group and 50 in the control group. None of the demographic variables (age, gender, residence and habits) were significantly different between the two groups. Otoscopy and tympanometry were normal in all patients and controls. The difference between the two groups in respect to frequency and severity of SNHL on PTA and in respect to unilateral and bilateral distribution of the hearing loss was not statistically significant.

CONCLUSION

There is no statistically significant difference in frequency and severity of SNHL between patients with ulcerative colitis in remission and healthy age- and sex-matched controls.

Neurology of inflammatory bowel disease

Inflammatory bowel diseases (IBD) are chronic inflammatory conditions affecting the digestive system, comprising two main distinctive entities, ulcerative colitis (UC) and Crohn's disease (CD). Besides gastrointestinal manifestations, IBD causes extraintestinal manifestations in the central and peripheral nervous system. The incidence of neurological complications in IBD ranges from 0.25% to 47.5%. The pathophysiology of neurological manifestations of IBD is mostly immune mediated, but dysfunction of the brain-gut axis, arterial and venous thromboembolism, infections, nutritional deficiencies and side-effects of medications (steroids, metronidazole, sulfasalazine, anti-TNF-α, anti-integrin antibodies) are other contributory mechanisms. Patients with IBD have an increased risk of arterial and venous stroke, mainly during periods of exacerbations. Vasculitis is extremely rare. There is a bidirectional association between multiple sclerosis and IBD, with a relative risk for comorbidity of 1.54, being 1.53 for the risk of multiple sclerosis in IBD and 1.55 for the risk of IBD in multiple sclerosis patients. Anti-TNF-α therapy is contraindicated in the treatment of patients who have both IBD and multiple sclerosis. Demyelinating disorders can also be a rare complication of anti-TNF-α therapy. Optic neuritis, transverse myelitis, progressive myelopathy, central nervous system infections, epilepsy and encephalopathy are among other uncommon neurological complications. Peripheral nervous system manifestations include peripheral neuropathy, either demyelination and axonal, myasthenia gravis and polymyositis/dermatomyositis and localized forms of myositis.

Hearing Loss in Patients with Inflammatory Bowel Disease

BACKGROUND AND AIMS

Inflammatory bowel disease (IBD) has many characteristics of autoimmune diseases. Sensorineural hearing loss has been reported in many autoimmune diseases. Little is known about hearing loss in patients with IBD.

METHODS

A prospective blinded comparative study was conducted over a 3-year period. IBD patients and controls underwent a complete otorhinolaryngeal examination and eudiometry test.

RESULTS

Altogether 105 participants (76 patients and 29 controls) took part in this study. Mean age was 36, 51 % were males, and 40 % of the patients were presently hospitalized due to IBD exacerbation. Audiometric examination revealed that any hearing loss (mild to severe) was found in 29 (38 %) of the IBD population, compared to 4 (14 %) of the control group (p = 0.02). Extraintestinal manifestation (EIM) was present in 33/76 (43 %) of IBD patients. Any hearing loss and moderate to severe hearing loss were found in 17/33 (52 %) and 7/33 (21 %) in the EIM-positive group compared to 12/43 (28 %) and 4/43 (9 %) in the EIM-negative group (p = 0.036 and p = 0.14, respectively). Out of patients over the age of 40 with other EIMs, all 11/11 (100 %) of patients had any hearing loss compared to 8/12 (66 %) of patients over the age of 40 without other EIMs, p = 0.035.

CONCLUSIONS

Hearing loss may be another EIM of IBD. It is found in 38 % of IBD patients and in up to 52 % of patients with other EIMs and increases over the age of 40. Early hearing evaluation should be recommended to these high-risk IBD patients.

Cogan's Syndrome in Patients With Inflammatory Bowel Disease--A Case Series

BACKGROUND

Cogan's syndrome (CSy) is a very rare autoimmune disorder, mainly affecting the inner ear and the eye, and is associated with inflammatory bowel disease (IBD).

METHODS

This was a European Crohn's and Colitis Organisation (ECCO) retrospective observational study, performed as part of the CONFER project. A call to all ECCO members was made to report concomitant CSy and inflammatory bowel disease (IBD) cases. Clinical data were recorded in a standardized questionnaire.

RESULTS

This international case series reports on 22 concomitant CSy-IBD cases from 14 large medical centres. Mean duration of IBD until diagnosis of CSy was 8.7 years (range 0.0-38.0) and mean age at CSy diagnosis was 44.6 years (range 9.0-67.0). Six patients had underlying ulcerative colitis (UC) and 16 had Crohn's disease. Eleven patients (50%) had active disease at CSy diagnosis. Sixteen patients were under IBD treatment at the time of CSy diagnosis, of whom 6 (37.5%) were on anti-tumour necrosis factor (TNF). Seven out of 10 patients, who were treated for CSy with immunomodulators (mostly with corticosteroids), demonstrated at least partial response.

CONCLUSION

This is the largest CSy-IBD case series so far. Although CSy is considered to be an autoimmune disease and is associated with IBD, immunomodulatory IBD maintenance treatment and even anti-TNF therapy do not seem to prevent disease onset. Moreover, IBD disease activity does not seem to trigger CSy. However, vigilance may prompt early diagnosis and directed intervention with corticosteroids at inception may potentially hinder audiovestibular deterioration. Finally, vigilance and awareness may also offer a better setting to study the pathophysiological mechanisms of this rare but debilitating phenomenon.

Sudden hearing loss and Crohn disease: when Cogan syndrome must be suspected

Cogan's syndrome is a rare systemic vasculitis of unknown origin. It is characterized by the presence of worsening audiovestibular and ocular symptoms that may manifest simultaneously or sequentially. No specific diagnostic laboratory tests or imaging studies exist. The diagnosis is clinical and should be established as early as possible so as to initiate prompt treatment with steroids and prevent rapid progression to deafness or blindness and potentially fatal systemic involvement. We report a case of association between Cogan's syndrome and ileal Crohn's disease which we believe deserves attention since, after an accurate review of the literature, we have found approximately 250 reports of patients with Cogan's syndrome, only 13 of whom with concurrent chronic inflammatory bowel disease; of these 13 cases, none experienced improvement after therapy. In the light of the good outcome obtained in our case, we proposed a valid treatment option with boluses of steroids, combined with early systemic immunosuppression and intra-tympanic steroid injections.

Function of the audiovestibular system in children with systemic lupus erythematosus

Systemic lupus erythematosus can affect inner ear by disrupting either the hearing or balance system. Affection of hearing can be anatomically categorized into conductive and sensorineural hearing loss, while affection of the equilibrium system manifests either as an isolated manifestation like vertigo or as a part of a spectrum like Meniere's disease. Most cases show asymptomatic affection requiring an objective audiovestibular assessment. More focus should be given to routine evaluation especially with disease flares and for proper treatment. In pediatric patients, more concern should be given owing to the added effect of ototoxicity with several drugs and the educational impact of such comorbidity.

Neurologic manifestations of inflammatory bowel diseases

Inflammatory bowel diseases (IBD) are chronic, relapsing and remitting inflammatory conditions affecting the digestive system, comprising two main distinctive diseases, ulcerative colitis (UC) and Crohn's disease (CD). Besides the classic gastrointestinal manifestations, a variable number of IBD patients present with extraintestinal manifestations, including central and peripheral nervous system involvement. Peripheral neuropathy is one of the most common complications. An inflammatory myopathy has also been found. Cranial neuropathies include the Melkersson-Rosenthal syndrome, optic neuritis, and sensorineural hearing loss. Patients with IBD have a remarkable thromboembolic tendency and are at increased risk of both venous and arterial thrombotic complications. The prothrombotic state in IBD has multiple contributors. Ischemic stroke occurs through several mechanisms, including large artery disease, small vessel disease, paradoxical embolism, endocarditis, vasculitis, and associated with anti-TNF-α therapy. Thrombosis of the dural sinus and cerebral veins are at least as frequent as arterial stroke in IBD. Multiple sclerosis has been repeatedly associated with IBD. Up to 50% of IBD present asymptomatic white matter lesions. Other central nervous system complications include a slowly progressive myelopathy, epidural and subdural spinal empyema secondary to fistulous extension from the rectum, seizures, and encephalopathy.

Bilateral sudden sensorineural hearing loss: review

Introduction:

Unilateral and bilateral sudden sensorineural hearing loss represent different disease entities. The unilateral condition is more common and predominantly idiopathic, and up to 65 per cent of patients spontaneously recover hearing. Conversely, the bilateral condition is rare, mostly associated with serious systemic conditions, and has a higher prevalence of morbidity and mortality.

Methods:

A literature search using the PubMed database was conducted using the MeSH terms ‘sudden’, ‘bilateral’ and ‘sensorineural hearing loss’.

Results:

One hundred and three reported cases of bilateral sudden sensorineural hearing loss were identified. The condition is most often associated with toxic, autoimmune, neoplastic and vascular conditions. A younger age of onset, with a bimodal age distribution, was seen for bilateral sudden sensorineural hearing loss, compared with the unilateral condition. Patients with the bilateral condition had more profound hearing loss, with poorer recovery and a 35 per cent mortality rate. Vestibular symptoms were also less common than in the unilateral condition.

Conclusion:

The presentation of bilateral sudden onset sensorineural hearing loss is a medical emergency requiring thorough and urgent investigation to exclude life-threatening and reversible conditions.

Association between Cogan's syndrome and inflammatory bowel disease: a case series

BACKGROUND AND AIMS

Cogan's syndrome (CS) is a rare autoimmune disease with less than 250 cases reported. It mainly affects the audiovestibular system and the eyes frequently resulting in deafness. Inflammatory bowel disease (IBD) consists of two subtypes, Crohn's disease (CD) and ulcerative colitis (UC), and represents a common form of chronic intestinal inflammation. Here, we report an association between CS and IBD in four patients.

METHODS

Patient data were collected using a questionnaire that was sent to one of our outpatients and three of the 13 members of the German CS self-help group.

RESULTS

In all Cogan patients with IBD (3 female with UC, 1 male with CD), intestinal disease was diagnosed years before the onset of CS. After suffering from a complicated IBD disease course, they suddenly developed CS-related symptoms, such as hearing loss, tinnitus or eye inflammation. Three of them went deaf within a few years after diagnosis. Although all of them had been on immunosuppressive IBD therapy, these treatment regimens did not prevent the onset of CS.

CONCLUSIONS

Our data suggest a strong association of IBD and CS. Since CS rapidly leads to bilateral deafness, it seems to be a rare, but nevertheless important disease that can occur in association with IBD. However, neither an early diagnosis nor an immunosuppressive therapy seems to efficaciously prevent disease progression.

Sudden sensorineural hearing loss

Sudden sensorineural hearing loss is usually unilateral and can be associated with tinnitus and vertigo. In most cases the cause is not identified, although various infective, vascular, and immune causes have been proposed. A careful examination is needed to exclude life threatening or treatable causes such as vascular events and malignant diseases, and patients should be referred urgently for further assessment. About half of patients completely recover, usually in about 2 weeks. Many treatments are used, including corticosteroids, antiviral drugs, and vasoactive and oxygen-based treatments. Although no treatment is proven, we recommend a short course of oral high-dose corticosteroids. There is much to learn about pathogenesis of sudden sensorineural hearing loss, and more clinical trials are needed to establish evidence-based management.

Sensorineural hearing loss in patients with inflammatory bowel disease

OBJECTIVE

The study aimed to discuss the association between sensorineural hearing loss (SNHL) and inflammatory bowel disease (IBD).

METHODS

We reviewed cases of patients with known IBD seen in an otolaryngology practice with documentation of all otologic data including age of onset, family history of otologic problems, exposure to noise, audiometric findings, and so on.

RESULTS

Of 38 patients with a history of IBD, 22 had documented SNHL. Nineteen of these had no other identifiable etiology for their inner ear dysfunction. Fourteen of these patients had a diagnosis of ulcerative colitis and 5 had Crohn disease. Sixteen patients had bilateral SNHL, and 3 patients had unilateral SNHL. Only one patient had a lasting response of SNHL to medical treatment.

CONCLUSION

This review suggests that SNHL is an extraintestinal association of IBD. As IBD is considered to be a local or systemic immunopathy, the associated SNHL might also be an expression of systemic immune dysfunction.

[Neurological complications of inflammatory bowel disease]

Although ulcerative colitis and Crohn's disease have traditionally been considered to be inflammatory diseases limited to the gastrointestinal tract, it has been shown that both pathologies are frequently accompanied by various extraintestinal disorders. There is an increasing evidence that they may also manifest in the nervous system, including the peripheral and the central parts. Although some of these neurological complications have been known for a long time, such as cerebrovascular disease, vasculitis and autoinmune processes including neuropathies and cerebral demyelination, others have been recently described. With the exception of some of this complications such as the thromboembolism, evidence for a casual relationship relies merely on single case reports or case series. In this article, we try to review the existing evidence on neurological manifestations of both variants of inflammatory bowel disease.

Asymptomatic Sensorineural Hearing Loss in Patients With Systemic Lupus Erythematosus

OBJECTIVE

Hearing loss can accompany systemic lupus erythematosus (SLE). The purpose of this study was to evaluate the prevalence of asymptomatic sensorineural hearing loss (ASNHL) in patients with SLE.

METHODS

Thirty-one unselected consecutive female patients with SLE (American College of Rheumatology criteria, 1982) were evaluated (in a prospective and descriptive study) for evidence of hearing abnormalities. Twenty-five healthy age-matched women served as controls. All patients and control groups underwent both a normal tympanoscopy and an audiometric testing as a prerequisite to be included in the study.

RESULTS

Patients with SLE had a mean age of 35 years (range, 19-64 years) and the follow-up time (median) was 48 months (range, 4-180 months). One of 31 patients was excluded because of middle ear infectious disease. Of the remaining 30 patients, 21 (70%) had impaired hearing; 20 (66%) had sensorineural loss at high frequencies in a bilateral and symmetric way, and one had conductive alteration. Ten patients had normal audiometric studies. Four women in the control group had alterations of the audiometric tests: 3 patients had conductive alteration and the other one had bilateral ASNHL. No statistically significant correlation was found among the presence of ASNHL, the detection of antiphospholipid antibodies, and the treatment with hydroxychloroquine. Also, no correlation was observed between impaired hearing and SLE activity.

CONCLUSION

If it can be established how often this ASNHL progresses to a clinical problem, it can be important that, as part of initial studies, patients with SLE undergo audiometric tests.

Extraintestinal manifestations and complications in inflammatory bowel diseases

Crohn’s disease (CD) and ulcerative colitis (UC) are chronic inflammatory bowel diseases (IBD) that often involve organs other than those of the gastrointestinal tract. These nonintestinal affections are termed extraintestinal symptoms. Differentiating the true extraintestinal manifestations of inflammatory bowel diseases from secondary extraintestinal complications, caused by malnutrition, chronic inflammation or side effects of therapy, may be difficult. This review concentrates on frequency, clinical presentation and therapeutic implications of extraintestinal symptoms in inflammatory bowel diseases. If possible, extraintestinal manifestations are differentiated from extraintestinal complications. Special attention is given to the more recently described sites of involvement; i.e. thromboembolic events, osteoporosis, pulmonary involvement and affection of the central nervous system.

Sensorineural hearing loss in patients with inflammatory bowel disease: a subclinical extraintestinal manifestation

Isolated case reports in which symptomatic hearing loss develops suddenly during the course of inflammatory bowel disease (IBD) have been reported, but the presence of subclinical sensorineural hearing loss (SNHL) associated with IBD has been investigated in only two preliminary studies. In order to research this further, we aimed to investigate the presence of subclinical SNHL in IBD by comparison with a control group and to examine possible relations between the bowel disease parameters and hearing loss.Otoscopy, tympanometry, and pure tone audiometry were carried out in 39 patients with IBD (21 Crohn's disease [CD], 18 ulcerative colitis [UC]) and 25 healthy age- and sex-matched controls. All patients and control subjects had normal otoscopy findings and tympanometry was unremarkable, excluding middle ear disease and conductive hearing loss. Analysis of each frequency examined showed that the average hearing thresholds were increased significantly in the study group compared to those of the control group at higher frequencies (2, 4, and 8 kHz). When these parameters were compared with the control group according to subgroups of IBD, a significant difference was determined for the UC group at frequencies of 2, 4, and 8 kHz and for the CD group only at the frequency of 4 kHz. Although there was a trend of increment in SNHL as the age of the patient and duration and extent of UC increased, no significant correlation was observed between SNHL and these parameters or sex, activity, involvement site, medication history of IBD, and coexistence of other extraintestinal manifestations. In conclusion, it was demonstrated that a subclinical SNHL may be associated with UC and somewhat with CD, affecting mainly the high frequencies. In light of this finding, it may be advisable to investigate labyrinth functions as well as other extraintestinal manifestations in patients with IBD.

The clustering of other chronic inflammatory diseases in inflammatory bowel disease: a population-based study

BACKGROUND & AIMS

We aimed to discern the relative risk for several chronic inflammatory conditions in patients with ulcerative colitis (UC) and Crohn's disease.

METHODS

We used the population-based University of Manitoba IBD Database that includes longitudinal files on all patients from all health system contacts identified by International Classification of Diseases, 9th revision, Clinical Modification codes for visit diagnosis. From the provincial database we extracted a control cohort matching the IBD patients 10:1 by age, sex, and geography. We considered a potential comorbid disease to be present if the patient had 5 or more health system contacts for that diagnosis. The comorbid disease period prevalence was analyzed separately for patients with UC and Crohn's disease and a prevalence ratio was calculated comparing the IBD populations with the matched cohort.

RESULTS

There were 8072 cases of IBD from 1984 to 2003, including UC (n = 3879) and Crohn's disease (n = 4193). There was a mean of approximately 16 person-years of coverage for both patients and control patients. Both UC and Crohn's disease patients had a significantly greater likelihood of having arthritis, asthma, bronchitis, psoriasis, and pericarditis than population controls. An increased risk for chronic renal disease and multiple sclerosis was noted in UC but not Crohn's disease patients. The most common nonintestinal comorbidities identified were arthritis and asthma.

CONCLUSIONS

The finding of asthma as the most common comorbidity increased in Crohn's disease patients compared with the general population is novel. These may be diseases with common causes or complications of one disease that lead to the presentation with another. Studies such as this should encourage further research into the common triggers in the organ systems that lead to autoimmune diseases.

The Deafness of Ludwig Van Beethoven: an Immunopathy

OBJECTIVE

To analyze and discuss the deafness of Ludwig van Beethoven (1770-1827) and to offer a logical theory for its etiology.

METHOD

The study will carefully review the composer's symptoms as described in his letters to friends and acquaintances and also will review a large body of source material, particularly publications by his contemporaries, some of which were generously loaned by Beethoven-Haus, Bonn, Germany, where necessary translations were made directly from the original German. We will also study publications on Inflammatory Bowel Disease (IBD) and its associated extraintestinal manifestations and personal discussions with experienced gastroenterologists.

RESULTS

Beethoven's abdominal symptoms that began in his teens are highly suggestive of IBD, which we believe to be a correct diagnosis. IBD is an umbrella term that includes a number of named entities such as ulcerative colitis and Crohn's Disease. IBD is now considered to be a problem of immune regulation with extra intestinal manifestations that include sensorineural hearing loss and primary sclerosing cholangitis (PSC). PSC eventually causes cirrhosis and failure of the liver. A diagnosis of IBD therefore provides a single entity that explains most of the composer's symptoms and was finally the cause of his death. Our conclusion is that Beethoven's sensorineural hearing loss was an immunopathy associated with IBD.

Autoimmune sensorineural hearing loss: Clinical course and treatment outcome

BACKGROUND

Autoimmune sensorineural hearing loss (ASHL) originally was defined both by the presence of progressive hearing loss (with or without vertigo) and a positive response to glucocorticoid therapy. Subsequently, antibodies to a 68-kd inner-ear antigen were identified in a high percentage of patients with ASHL.

OBJECTIVE

To analyze the disease progression and treatment outcome of ASHL.

METHODS

Retrospective chart review of 30 patients with a diagnosis of ASHL referred to Texas Tech Rheumatology Clinic. All subjects were tested for anti-68-kd antibody, had audiometric evidence of hearing loss, and were treated with glucocorticoids.

RESULTS

The median duration from onset of symptoms to audiometric testing was 25.5 weeks (mean, 144 weeks; range, 3-1,040 weeks), and to testing for anti-68-kd antibody was 40 weeks (mean, 157.3; range, 4-1,092 weeks). Ninety percent of subjects tested positive for anti-68-kd antibodies. By audiometric testing, 50% of subjects were steroid-responsive; minimal improvement or no change was recorded in 12%, and worsening occurred in 39% after steroid therapy. The 3 subjects who were anti-68-kd antibody-negative were steroid-unresponsive, and 1 progressed to complete deafness.

CONCLUSIONS AND RELEVANCE

This series of patients with ASHL suggests a more variable and benign course with a better prognosis than previously reported. Immunosuppressive therapy other than steroids rarely was required, and rapid progression to complete hearing loss was very uncommon in this cohort.

Autoimmune sensorineural hearing loss improved by tumor necrosis factor-alpha blockade: a case report

Autoimmune inner ear disease is a treatable cause of sensorineural hearing loss and it is important for physicians and hearing health professionals to recognize that early diagnosis and proper management strategies may result in stabilization and improvement in hearing. The pathogenesis of autoimmune sensorineural hearing loss remains unclear but antibodies directed against the inner ear and/or cellular effectors have been proposed. Therefore, immunosuppressive drugs such as steroids and methotrexate are administered to interfere with the progression of hearing loss and in some cases have been found to improve hearing. We report herein the history of a patient who was treated by systemic administration of anti-tumor necrosis factor-alpha antibodies for Crohn's disease and who also had associated sensorineural hearing loss. Audiometric follow-up revealed not only the efficacy of tumor necrosis factor-alpha blockade in arresting the hearing loss but also an improvement in hearing of 15 dB on average across all frequencies. Hearing remained stable afterwards.

[Cochlear hemorrhage. Unusual cause of sudden sensorineural deafness]

Sudden sensorineural hearing loss (SNHL) caused by intralabyrinthine hemorrhage is a rare entity usually associated to patients with previous pathological factors, such as blood dyscrasias, anticoagulant therapy and local hemorrhagic pathologies. We report the first-published case of sudden-onset deafness due to cochlear hemorrhage in a patient with no previous pathologies. We describe the history, diagnosis and follow-up of this patient in comparison to others previously published.

Autoimmune inner ear disease

The known etiologies of acquired sensorineural hearing loss include acoustic trauma, physical trauma, ototoxicity, genetic predisposition, infections, Meniere's disease, aging, and autoimmune disease. Treatments are directed at eliminating or managing the underlying disease process and aiding hearing with amplification. Rarely is it possible to improve unaided hearing after sensorineural loss except when the severe to profound level of loss is reached and cochlear implantation becomes an option. Autoimmune inner ear disease, however, is a treatable cause of sensorineural hearing loss and it is important for physicians and hearing health professionals to recognize that proper early diagnosis and management strategies may result in stabilization and possibly improvement in hearing.
