Consensus for the Early Identification of Secondary Progressive Multiple Sclero...
Sá, MJ; Basílio, C; Capela, C; Cerqueira, JJ; Mendes, I; Morganho, A; Correia de Sá, J; Salgado, V; Martins Silva, A; Vale, J; Sousa, LIntroduction: Multiple sclerosis is a disease with a heterogeneous evolution. The early identification of secondary progressive multiple sclerosis is a clinical challenge, which would benefit from the definition of biomarkers and diagnostic tools applicable in the transition phase from relapsing-remitting multiple sclerosis to secondary progressive multiple sclerosis. We aimed to reach a Portuguese national con...
Late Onset Neuromyelitis Optica Spectrum Disorders (LONMOSD) from a Nationwide ...
Santos, E; Moura, J; Samões, R; Sousa, AP; Mendonça, T; Abreu, P; Guimarães, J; Correia, I; Durães, J; Sousa, L; Ferreira, J; de Sá, J; Sousa, FIntroduction: Several neuroimmunological disorders have distinct phenotypes according to the age of onset, as in multiple sclerosis or myasthenia gravis. It is also described that late onset NMOSD (LONMOSD) has a different phenotype. Objective: To describe the clinical/demographic characteristics of the LONMOSD and distinguish them from those with early onset (EONMOSD). Methods: From a nationwide Portuguese NMO...
Cognitive impairment and markers of optical neurodegeneration in early multiple...
Silva, R; Coelho, P; Seabra, M; Laranjinha, I; Vieira, D; Costa, O; Jesus, J; Fonseca, AC; Costa, S; Ferreira, I; Lemos, J; Sousa, C; Vale, J; Sá, MJIntroduction: Cognitive impairment and retinal atrophy have been proposed as two potential markers of neurodegeneration in multiple sclerosis (MS). We aimed at assessing the relation between peripapillary retinal nerve fiber layer (pRNFL) and macular ganglion cell layer (mGCL) atrophy and cognitive performance in early MS. Methods: This is a multicenter cross-sectional study on patients with early MS (clinicall...

Santos, E; Rocha, AL; Oliveira, V; Ferro, D; Samões, R; Sousa, AP; Figueiroa, S; Mendonça, T; Abreu, P; Guimarães, J; Sousa, R; Melo, C; Correia, IIntroduction: Neuromyelitis optica spectrum disorder (NMOSD) is a rare disorder in which astrocyte damage and/or demyelination often cause severe neurological deficits. Objective: To identify Portuguese patients with NMOSD and assess their epidemiological/clinical characteristics. Methods: This was a nationwide multicenter study. Twenty-four Portuguese adult and 3 neuropediatric centers following NMOSD patients...

Multiple sclerosis, disease-modifying therapies and COVID-19: A systematic revi...
Cabreira, V; Abreu, P; Soares-Dos-Reis, R; Guimarães, J; Sá, MJUnderstanding the risks of COVID-19 in patients with Multiple Sclerosis (MS) receiving disease-modifying therapies (DMTs) and their immune reactions is vital to analyze vaccine response dynamics. A systematic review on COVID-19 course and outcomes in patients receiving different DMTs was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Emerging data on SAR...
The epidemiology of multiple sclerosis in the entre Douro e Vouga region of nor...
Branco, M; Alves, I; Martins, de Silva, A; Pinheiro, J; Sá, MJ; Correia, I; Sousa, L; Brandão, E; Veira, C; Gomes, B; Ruano, LBackground. The prevalence of Multiple Sclerosis (MS) has been increasing worldwide and the north–south gradient of prevalence may be disappearing in the Northern hemisphere. The few previous prevalence studies performed in Portugal have reported a lower prevalence than the average for Western Europe. The aim of this study is to estimate the prevalence of MS in the Entre Douro e Vouga region, in Northern Portug...
A Multicenter, Non-Interventional Study to Evaluate the Disease Activity in Mul...
Ladeira, F; Braz, L; Salgado, P; Vaz, S; Leitão, L; Félix, C; Correia, AS; Martins da Silva, A; Salgado, V; Ferreira, F; Vale, J; Sá, MJ; Capela, CObjectives: Natalizumab (NTZ) is very effective for treatment of relapsing-remitting multiple sclerosis (RRMS), its use is mainly limited by safety issues. Discontinuation of NTZ is associated with recurrence of disease activity (reactivation and rebound). The best strategy for subsequent therapy and the predictive factors for recurrence in such patients are areas of active research. We aimed to evaluate predic...
Genomic imbalances defining novel intellectual disability associated loci
Lopes, F; Torres, F; Soares, G; Barbosa, M; Silva, J; Duque, F; Rocha, M; Sá, J; Oliveira, G; Sá, MJ; Temudo, T; Sousa, S; Marques, C; Lopes, SBackground: High resolution genome-wide copy number analysis, routinely used in clinical diagnosis for several years, retrieves new and extremely rare copy number variations (CNVs) that provide novel candidate genes contributing to disease etiology. The aim of this work was to identify novel genetic causes of neurodevelopmental disease, inferred from CNVs detected by array comparative hybridization (aCGH), in a...
