Usefulness of optic nerve ultrasound to predict clinical progression in multiple sclerosis

Introducción La pérdida neuronal/axonal progresiva se considera la causa más importante de discapacidad neurológica en la esclerosis múltiple (EM). El sistema visual está frecuentemente afectado en esta enfermedad y su accesibilidad a test funcionales y estructurales ha permitido que se convierta en un modelo para estudiar in vivo la patogenia de la EM. La ecografía orbitaria permite evaluar, de forma no invasiva y en tiempo real, las diversas estructuras de la órbita, incluido el nervio óptico. Material y métodos Se ha llevado a cabo un estudio observacional ambispectivo en pacientes con EM recogiéndose datos evolutivos de la enfermedad. La ecografía orbitaria se realizó en todos los pacientes según el principio de mínima potencia necesaria (ALARA). También se recogieron los datos de tomografía de coherencia óptica (OCT) en aquellos que tenían realizadas ambas pruebas. El estudio estadístico se efectuó con el programa SPSS 22.0. Resultados Se encontraron correlaciones estadísticamente significativas entre las medidas ecográficas y la progresión de la enfermedad (p = 0,041 para el ojo derecho y p = 0,037 para el ojo izquierdo), y la Expanded Disability Status Scale (EDSS) final en el seguimiento (p = 0,07 para el ojo derecho y p = 0,043 para el ojo izquierdo). No fue así para los datos referentes a brotes y a otras variables clínicas. Discusión La medición del diámetro del nervio óptico por ecografía podría utilizarse como medida predictiva en la evolución de la EM, ya que la disminución del mismo se asocia con progresión clínica y mayor discapacidad, medidas con la EDSS.Introduction Progressive neuronal and axonal loss are considered the main causes of disability in patients with multiple sclerosis (MS). The disease frequently involves the visual system; the accessibility of the system for several functional and structural tests has made it a model for the in vivo study of MS pathogenesis. Orbital ultrasound is a non-invasive technique that enables various structures of the orbit, including the optic nerve, to be evaluated in real time. Material and methods We conducted an observational, ambispective study of MS patients. Disease progression data were collected. Orbital ultrasound was performed on all patients, with power set according to the ‘as low as reasonably achievable’ (ALARA) principle. Optical coherence tomography (OCT) data were also collected for those patients who underwent the procedure. Statistical analysis was conducted using SPSS version 22.0. Results Disease progression was significantly correlated with ultrasound findings (P = .041 for the right eye and P = .037 for the left eye) and with Expanded Disability Status Scale (EDSS) score at the end of the follow-up period (P = .07 for the right eye and P = .043 for the left eye). No statistically significant differences were found with relation to relapses or other clinical variables. Discussion Ultrasound measurement of optic nerve diameter constitutes a useful, predictive factor for the evaluation of patients with MS. Smaller diameters are associated with poor clinical progression and greater disability (measured by EDSS)

Cultural adaptation and validation of a peninsular Spanish version of the MSTCQ(C) Multiple sclerosis; (Multiple Sclerosis Treatment Concerns Questionnaire)

Introduction: Although subcutaneous treatments for multiple sclerosis (MS) have been shown to be effective, adverse reactions and pain may adversely affect treatment satisfaction and adherence. This study presents an adapted and validated Spanish version of the Multiple Sclerosis Treatment Concerns Questionnaire (c) (MSTCQ), which evaluates satisfaction with the injection device (ID) across 4 domains: injection system (A), side effects (B) (flu-like symptoms, reactions, and satisfaction), experience with treatment (C) and benefits (D). Methods: Two study phases: 1) Cultural adaptation process with input from experts (n = 6) and patients (n = 30). 2) Validation obtained by means of an observational, cross-sectional, multi centre study evaluating 143 adult MS patients using an ID. Tools employed: MSTCQ, Patient Reported Indices for Multiple Sclerosis (PRIMUS), and Treatment Satisfaction Questionnaire for Medication (TSQM (c)). Psychometric properties: Feasibility (percentage of valid cases and floor/ceiling effects); Reliability (Cronbach alpha) and test-retest correlation (n =41, intractass correlation coefficient, ICC); and construct validity (factor analysis of domains A and B) and convergent validity (Spearman rank-order correlation for MSTCQ (c) vs TSQM (c)). Results: Mean age (SD) was 41.94 (10.47) years, 63% of the group were women, and 88.11% presented relapsing-remitting MS. Mean (SD) EDSS score was 2.68 (1.82) points. MSTCQ (c) completion was high (0%-2.80% missing data). Internal consistency was high at alpha = 0.89 for the total score (A+ B) and alpha = 0.76, 0.89, and 0.92 for domains A, B, and C, respectively. The version demonstrated excellent test-retest reliability for the total (ICC = 0.98) and for domains A, B, and C: ICC =0.82, 0.97, and 0.89, respectively. Factor analysis corroborated the internal structure of the original questionnaire. The association between total and domain scores on both the MSTCQ (c) and the TSQM (c) was moderately strong (Rho = 0.42-0.74) and significant (
