|February 3, 2016
Summary
This study found antibodies against inner ear antigens in patients with hearing loss and Menière's disease, supporting autoimmune inner ear disease. Immunosuppressive therapy improved symptoms in these patients.
Area of Science:
- Immunology
- Otolaryngology
- Neurology
Background:
- The hypothesis of autoimmune inner ear disease was proposed by McCabe in 1979.
- This study investigates the immune response in cochleovestibular disorders.
Purpose of the Study:
- To demonstrate the presence of antibodies against inner ear antigens in patients with specific cochleovestibular disorders.
- To evaluate the efficacy of immunosuppressive therapy in these conditions.
Main Methods:
- Serum samples from 74 subjects (25 with idiopathic progressive sensorineural hearing loss, 25 with Menière's disease, and 24 healthy controls) were analyzed using sodium dodecyl sulfate polyacrylamide gel electrophoresis and immunoblotting.
- Antibodies against inner ear antigens were detected.
- Patients with detected antibodies received immunosuppressive therapy.
Main Results:
- Antibodies against inner ear antigens (30, 50, 60, 80, 100 kDa) were found in 52% of patients with idiopathic progressive sensorineural hearing loss and 44% with Menière's disease, but not in healthy controls.
- Hearing improved in 69% of patients with idiopathic progressive sensorineural hearing loss.
- Hearing improved in 72% and vertigo significantly improved in 81% of patients with Menière's disease.
Conclusions:
- The findings support the hypothesis of immune-mediated cochleovestibular disease.
- The study highlights the potential role of the immune system in the pathogenesis of these disorders.
- Immunosuppressive therapy shows promise for treating these conditions.

01:15Equilibrium and Balance
7.9K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

01:29The Vestibular System
45.0K
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.

19
Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...

01:13The Cochlea
52.4K
The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.

01:16Anatomy of the Ear
13.6K
Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
