Neuromyelitis Optica Spectrum Disorder in Latin America: State-of-the-Art and Current Challenges.

Neuromyelitis optica spectrum disorder (NMOSD) is a rare autoimmune disease of the central nervous system characterized by severe attacks of optic neuritis, myelitis, and/or area postrema. Advances in understanding the pathophysiology of NMOSD have led to improved diagnostic and therapeutic approaches. There has been a notable increase in research efforts worldwide, including in Latin America (LATAM). In recent years, LATAM has witnessed a surge in research on NMOSD, resulting in a growing body of evidence on various aspects such as epidemiology, clinical manifestations, paraclinical features (including AQP4-IgG [Aquaporin-4-immunoglobulin G] and imaging), acute and long-term treatment strategies, as well as accessibility to diagnostic tests. This narrative review aims to present the most relevant findings from different NMOSD cohorts in LATAM, providing a comprehensive overview of the current understanding of the disease in the region, while considering its unique characteristics and challenges. LATAM-focused evidence is crucial for adding valuable information to the international dataset and is therefore summarized in this review.

Consenso sobre la identificación y seguimiento de la esclerosis múltiple secundaria progresiva en Argentina / Argentinean consensus guidelines on the identification and clinical care of secondary progressive multiple sclerosis

INTRODUCCIÓN: Existen diferencias significativas en el diagnóstico, la identificación y el seguimiento de pacientes con esclerosis múltiple secundaria progresiva (EMSP) entre los profesionales de la salud a cargo de su tratamiento. OBJETIVO: Proveer recomendaciones sobre el tratamiento de los pacientes con EMSP en Argentina con el fin de optimizar su cuidado. DESARROLLO: Un grupo de neurólogos expertos en esclerosis múltiple de Argentina elaboró un consenso para el tratamiento de pacientes con EMSP en la región mediante metodología de ronda de encuestas a distancia y reuniones presenciales. Se establecieron 33 recomendaciones basadas en la evidencia publicada y en el criterio de los expertos que participaron. Las recomendaciones se enfocaron en el diagnóstico y el seguimiento de los pacientes con EMSP. CONCLUSIÓN: Las recomendaciones establecidas en el presente consenso permitirían optimizar el cuidado y el seguimiento de los pacientes con EMSP en Argentina

INTRODUCTION: The identification, diagnosis, follow-up, and treatment of patients with secondary progressive multiple sclerosis (SPMS) show significant differences between health care professionals in Argentina. AIM: To provide consensus recommendations on the management of patients with SPMS in Argentina to optimize patient care. DEVELOPMENT: A panel of expert neurologists from Argentina dedicated to the diagnosis and care of multiple sclerosis patients gathered during 2019 and 2020 to carry out a consensus recommendation on the diagnosis and treatment of SPMS patients in Argentina. To achieve consensus, the methodology of formal consensus-RAND/UCLA method was used. Recommendations were established based on published evidence and the expert opinion. Recommendations focused on how to define SPMS and how to follow SPMS patients. CONCLUSION: The recommendations of this consensus guidelines attempt to optimize the care of SPMS patients in Argentina
