Active clinical trials for "Neuritis"

To evaluate the optical coherence tomography (OCT), visual field (VF), Visual evoked po-tential(VEP) characteristics between neuromyelitis optica- related optic neuritis (NMOSD-ON) and multiple sclerosis- related ON (MS-ON) in a Chinese cohort.

Using a technique called adaptive optics imaging applied on retina, investigators aim to gain access to vascular changes that could occur early in the course of Multiple Sclerosis (MS) and which could reflect vascular changes occurring along the optic nerve of the brain parenchyma. Indeed, our team has been able to develop a quantitative method to measure the perivascular infiltrate in the retina of patients with various inflammatory retinal disease. It has been observed in MS patients that this perivascular infiltrate can also be detected in the retina. However, its distribution across MS phenotypes (relapsing or progressive MS, with and without optic neuritis) is still unknown.

The purpose of investigation is to assess the levels of metabolic factors (hydroxyvitamin D, homocysteine) between patients with vestibular dysfunction of peripheral origin (BPPV) and central origin (vestibular migraine). Also we will analyse another factors (such as anxiety and depression) and optimize therapeuthical approach accordingly with the data.

Vestibular neuritis is the second cause of vertigo, it constitutes 5 to 6% of the aetiologies of vertigo in an otoneurological consultation. Infection or reactivation of a neurotropic virus of the herpes group (HSV-1) in the vestibular lymph node is thought to be the cause of the unilateral vestibular deficit. Upper vestibular neuritis is more common than lower, or total involvement. Goebel (2) explains this by an anatomical predisposition of the vestibular nerve canal to inflammation, unlike the singular nerve canal which is shorter and wider giving way to a certain degree of edema without consequence on its contents. However, the innervation territory of the superior vestibular nerve is superimposable on the territory supplied by the anterior vestibular artery. The anterior, lateral semicircular canals and the utricle are affected. Current complementary vestibular and imaging examinations cannot differentiate between inflammatory or vascular involvement in upper vestibular neuritis. The increased presence of cardiovascular risk factors in patients with upper vestibular neuritis would be an argument in favor of ischemic involvement of the anterior vestibular artery.

Improved means of positive diagnosis of facial neuritis, the leading cause of peripheral facial palsy

This study evaluates the length of optic nerve lesion on 3D-DIR sequence as an imaging biomarker predictive of retinal axonal loss and visual disability, 12 months after the occurence of a first clinical episode of optic neuritis.

This will be a hospital-based retrospective multi-center study on epidemiologic and clinical characteristics of optic neuritis among Chinese. The investigation will cover about 29 provinces or municipalities all around China.
