Neuromyelitis optica spectrum disorder (NMOSD) is a rare disease that commonly presents with optic nerve and spinal cord inflammation, and it is associated with the presence of aquaporin-4 immunoglobulin G antibody (AQP4-IgG). Information on the clinical profile and occurrence of NMOSD among Filipino patients, however, is not sufficiently documented. In this series, we presented eighteen (18) patients with NMOSD consecutively seen in the Philippine General Hospital, a major tertiary referral center. Demographic data showed a female-to-male ratio of 2.6:1. Median age of onset of symptoms was 26 years. Eight patients (53.3%) were positive for AQP4-IgG. Most patients initially presented with myelitis (56.6%) and followed by optic neuritis (16.7%) and area postrema syndrome (16.7%). All patients had longitudinally extensive transverse myelitis on magnetic resonance imaging (MRI). Cranial MRI rarely demonstrated lesions in the optic nerves (18.2%). CSF pleocytosis (33%) and increased protein (8.3%) were infrequent. These results demonstrated that the profile of Filipino patients with NMOSD seen in our institution strengthens those described in other populations with this disorder. Large scale cross-sectional studies are necessary to fully define the profile of these patients and to determine with accuracy the prevalence and incidence of this disorder in the Philippines. Further investigation regarding the utility of ancillary tests as diagnostic and prognostic indicators in patients with NMOSD are also suggested by the authors.

Neuromyelitis optica spectrum disorder (NMOSD) is a B-cell-mediated disease with autoimmunity towards the astrocyte water channel aquaporin-4 (AQP-4) in the central nervous system.
Neuromyelitis optica spectrum disorder (NMOSD) was suggested to be more frequent and have specific features among populations from Africa or North Africa. However, we could not find any large study ab...
The relation between brain functional connectivity of patients with neuromyelitis optica spectrum disorder (NMOSD) and the degree of disability remains unclear.
Certain disease-modifying drugs for multiple sclerosis are known to be ineffective in treating neuromyelitis optica spectrum disorder (NMOSD), and can even induce subsequent relapses.
To develop and validate an individual radiomics nomogram for differential diagnosis between multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD).
The purpose of this study is to initially observe the safety and effectivity of RC18 in Participants with Neuromyelitis Optica Spectrum Disorders.
In neuromyelitis optica spectrum disorder (NMOSD),interleukin-6 (IL-6) may play an important role in facilitating plasma cells to produce pathological aquaporin 4 (AQP4) autoantibody. Inhi...
Neuromyelitis Optica Spectrum Disorders (NMOSD) are a group of inflammatory demyelinating disorders of the central nervous system. Although NMOSD occurs much more commonly in nations with ...
The purpose of this study is to compare annual relapse rate, expanded disability status scale, and side effects of azathioprine and rituximab in patients with neuromyelitis optica spectrum...
This study is being done to develop a database of pediatric patients in order to study the cause, early detection and best treatment for neuromyelitis optica spectrum disorder (NMOSD) in p...
A syndrome characterized by acute OPTIC NEURITIS in combination with acute MYELITIS, TRANSVERSE. Demyelinating and/or necrotizing lesions form in one or both optic nerves and in the spinal cord. The onset of optic neuritis and myelitis may be simultaneous or separated by several months. (J Neurol Neurosurg Psychiatry 1996 Apr;60(4):382-387)
A system for classifying patient care by relating common characteristics such as diagnosis, treatment, and age to an expected consumption of hospital resources and length of stay. Its purpose is to provide a framework for specifying case mix and to reduce hospital costs and reimbursements and it forms the cornerstone of the prospective payment system.
The expenses incurred by a hospital in providing care. The hospital costs attributed to a particular patient care episode include the direct costs plus an appropriate proportion of the overhead for administration, personnel, building maintenance, equipment, etc. Hospital costs are one of the factors which determine HOSPITAL CHARGES (the price the hospital sets for its services).
An isomer of butanol that contains a tertiary butyl group that consists of three methyl groups, each separately attached to a central (tertiary) carbon.
The prices a hospital sets for its services. HOSPITAL COSTS (the direct and indirect expenses incurred by the hospital in providing the services) are one factor in the determination of hospital charges. Other factors may include, for example, profits, competition, and the necessity of recouping the costs of uncompensated care.
Spinal Cord Disorders
The spinal cord is a bundle of nerves that runs down the middle of the back which carry signals back and forth between the body and brain. It is protected by vertebrae, which are the bone disks that make up the spine. An accident that damages the verte...
An antibody is a protein produced by the body's immune system when it detects harmful substances, called antigens. Examples of antigens include microorganisms (such as bacteria, fungi, parasites, and viruses) and chemicals. Antibodies may be produc...
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
