Sera from Patients with NMOSD Reduce the Differentiation Capacity of Precursor Cells in the Central Nervous System.

Int J Mol Sci 2021 May 14;22(10). Epub 2021 May 14.

Laboratory of Neurobiology, Department of Neurology, Institute of Neurosciences, San Carlos Health Research Institute, Universidad Complutense, 28040 Madrid, Spain.

Introduction: AQP4 (aquaporin-4)-immunoglobulin G (IgG)-mediated neuromyelitis optica spectrum disorder (NMOSD) is an inflammatory demyelinating disease that affects the central nervous system, particularly the spinal cord and optic nerve; remyelination capacity in neuromyelitis optica is yet to be determined, as is the role of AQP4-IgG in cell differentiation.

Material And Methods: We included three groups-a group of patients with AQP4-IgG-positive neuromyelitis optica, a healthy group, and a sham group. We analyzed differentiation capacity in cultures of neurospheres from the subventricular zone of mice by adding serum at two different times: early and advanced stages of differentiation. Read More

Multimodal Evoked Potentials as Candidate Prognostic and Response Biomarkers in Clinical Trials of Multiple Sclerosis.

J Clin Neurophysiol 2021 May;38(3):171-180

Section of Clinical Neurophysiology, Department of Neurology, Hospital of the University of Basel, Basel, Switzerland.

Summary: Evoked potentials (EPs) measure quantitatively and objectively the alterations of central signal propagation in multiple sclerosis and have long been used for diagnosis. More recently, their utility for prognosis has been demonstrated in several studies, summarizing multiple EP modalities in a single score. In particular, visual, somatosensory, and motor EPs are useful because of their sensitivity to pathology in the frequently affected optic nerve, somatosensory tract, and pyramidal system. Read More

[Aquaporin 4 antibody-positive neuromyelitis optica spectrum disorders and myelin oligodendrocyte glycoprotein antibody-associated encephalomyelitis. A brief review].

Nervenarzt 2021 Apr 31;92(4):317-333. Epub 2021 Mar 31.

AG Molekulare Neuroimmunologie, Neurologische Klinik, Universitätsklinik Heidelberg, Heidelberg, Deutschland.

Aquaporin 4 (AQP4) immunoglobulin (Ig)G-associated neuromyelitis optica spectrum disorders (NMOSD) and myelin oligodendrocyte glycoprotein immunoglobulin (Ig)G-associated encephalomyelitis (MOG-EM, also termed MOG antibody-associated disease, MOGAD) are important autoimmune differential diagnoses of multiple sclerosis (MS), which differ from MS with respect to optimum treatment and prognosis. AQP4 IgG-positive NMOSD take a relapsing course in virtually all cases and MOG-EM in at least 80% of adult cases. Both diseases can quickly lead to permanent disability if left untreated, although MOG-EM is associated with a better overall long-term prognosis. Read More

[From neuromyelitis optica to neuromyelitis optica spectrum disorder: from clinical syndrome to diagnistic classification].

Nervenarzt 2021 Apr 16;92(4):307-316. Epub 2021 Mar 16.

Institut für klinische Neuroimmunologie, LMU Klinikum, Ludwig-Maximilians-Universität München, Marchioninistr. 15, 81377, München, Deutschland.

Neuromyelitis optica spectrum disorder (NMOSD), derived from NMO or Devic's disease, is considered as a distinct disease since the discovery of a novel and pathogenic serum autoantibody targeting aquaporin‑4 (AQP4-IgG) and is distinguished from classical multiple sclerosis (MS). With the continuous extension of knowledge on the clinical manifestations, the previously narrow diagnostic term NMO became NMOSD, which has also been used in the diagnostic criteria since 2015. The current diagnostic criteria enable the early diagnosis of NMOSD in patients with and without AQP4-IgG. Read More

[Evidence-based guidelines for diagnosis and treatment of demyelinating optic neuritis in China(2021)].

Authors:

Zhonghua Yan Ke Za Zhi 2021 Mar;57(3):171-186

Demyelinating optic neuritis (DON) is an inflammatory demyelinating disease of the central nervous system, which can lead to visual loss in young adults as a major factor. The key points concerned by neuro-ophthalmologists are to reduce the rate of recurrence and improve the prognosis in the course of diagnosis and treatment of DON. Companied with the deep research of diagnostic markers, different classifications and therapies, and evidence-based medicine, there are more and more clinical evidences for the development and standardization of evidence-based guidelines for diagnosis and treatment.

From the Department of Neurology (J.L., K.C.F., O.C.M., A.G.F., E.S.S., G.K., E.V., N.P., E.O., B.T., N.J.L., S.D., N.F., O.K., H.R., S.D.N., E.M.M., S.S., P.A.C.), Johns Hopkins University School of Medicine; and Departments of Biostatistics (C.M.C.) and Electrical and Computer Engineering (J.L.P.), Johns Hopkins University, Baltimore, MD.

Objective: To evaluate whether a retinal spectral-domain optical coherence tomography (SD-OCT) assessment at baseline is associated with long-term disability worsening in people with multiple sclerosis (PwMS), we performed SD-OCT and Expanded Disability Status Scale (EDSS) assessments among 132 PwMS at baseline and at a median of 10 years later.

Methods: In this prospective, longitudinal study, participants underwent SD-OCT, EDSS, and visual acuity (VA) assessments at baseline and at follow-up. Statistical analyses were performed using generalized linear regression models, adjusted for age, sex, race, multiple sclerosis (MS) subtype, and baseline disability. Read More
