Repeated Treatment With Rituximab Based on the Assessment of Peripheral Circulating Memory B Cells in Patients With Relapsing Neuromyelitis Optica Over 2 Years Su-Hyun Kim, MD; Woojun Kim, MD, PhD; Xue Feng Li, MD, MSc; In-Ja Jung, RN; Ho Jin Kim, MD, PhD Arch Neurol. ?2011;68(11):1412-1420. doi:10.1001/archneurol.2011.154 Objective? To evaluate the efficacy and safety of repeated rituximab treatment based on the assessment of peripheral circulating memory B cells over 24 months in patients with relapsing neuromyelitis optica (NMO).
Purpose: To prospectively assess sensitivity and specificity of diffusion indexes of the corpus callosum (CC) for differentiating relapsing neuromyelitis optica (RNMO) from relapsing-remitting multiple sclerosis (RRMS), by using final clinical diagnosis as the reference standard. Materials and Methods: Participants provided informed consent; the study was approved by the institutional review board. Forty-six consecutive patients with RRMS (18 men, 28 women; mean age, 37.7 years; range, 18–58 years) and 26 consecutive patients with RNMO (two men, 24 women; mean age, 38.6 years; range, 19–59 years) underwent diffusion-tensor magnetic resonance imaging.

BACKGROUND: The role of different chemokine receptors in the pathogenesis of multiple sclerosis (MS) has been extensively investigated; however, little is known about the difference in the role of chemokine receptors between the pathogenesis of neuromyelitis optica (NMO) and MS. Therefore, we examined the expression of chemokine receptors on peripheral blood lymphocytes (PBL) in MS and NMO. METHODS: We used flow cytometry to analyse lymphocyte subsets in 12 patients with relapsing NMO, 24 with relapsing-remitting MS during relapse, 3 with NMO and 5 with MS during remission.
We evaluated 30 patients with clinically definite multiple sclerosis (MS) and 8 patients with neuromyelitis optica (NMO) to investigate correlations between Th1/Th2 balance, disease activity, effects of interferon (IFN)-beta treatment, and expressions of chemokine receptors CXCR3 and CCR4 on CD4+ and CD8+ T cells in peripheral blood. MS and NMO patients in the relapsing phase showed a significantly increased CD4+CXCR3+/CD4+CCR4+ ratio and CD8+CXCR3+/CD8+CCR4+ ratio compared with respective patients in the remission phase
Neuromyelitis optica (NMO) is a relapsing inflammatory condition characterized by selective involvement of the optic nerves and spinal cord. Humoral immune mechanisms play a role in the pathogenesis of NMO.
Neuromyelitis optica (NMO) is a relapsing inflammatory disorder of the central nervous system that closely resembles multiple sclerosis.
A 21-year-old right-handed woman suffered cervical myelitis in 1971, followed by two episodes of bilateral optic neuritis and four relapses of thoracic or lumbar myelitis through 1998. Her initial brain MRI in 1989 revealed no abnormality, which met the MRI criteria for multiple sclerosis. In 2009, her serum anti-aquaporin-4 antibody was found to be positive, and a diagnosis of relapsing neuromyelitis optica (NMO) was made on the basis of current diagnostic criteria
OBJECTIVE: To evaluate the efficacy and safety of mitoxantrone hydrochloride and determine how it exhibits a differential inhibitory effect on subsets of B cells in patients with highly relapsing neuromyelitis optica (NMO).
Neuromyelitis optica (NMO), characterised by longitudinally extensive transverse myelitis (LETM), was previously thought to be a variant of multiple sclerosis.
Background and Objective: Our objective was to characterize the clinical and radiologic features of Korean pediatric patients with relapsing central nervous system (CNS) demyelination disease.
