ABSTRACT

RESUMEN Fundamento: los fármacos modificadores, en la esclerosis múltiple, tienen la finalidad de reducir la frecuencia de recaídas, retardar la progresión de la discapacidad, así como la aparición de nuevas lesiones en el Sistema Nervioso Central. Objetivo determinar los indicadores precoces de respuesta al tratamiento con IFNb-1ª en pacientes con esclerosis múltiple remitente-recurrente. Métodos: estudio observacional, analítico de cohorte con prospectiva longitudinal en los pacientes con diagnóstico de esclerosis múltiple. Se conformaron dos cohortes de estudio, cada una con 39 pacientes. Resultados: la media y desviación estándar de la escala ampliada del estado de discapacidad a los 36 meses fue de 2.37 ± 1.86 en el grupo estudio y en el control de 3.15 ± 2.1. En los brotes de .13 ± .33 en el grupo estudio y en el grupo control de .41 ± .59. Las lesiones nuevas en T2 tras los 12 primeros meses de tratamiento fue de 0.90 ± 1.16 para el grupo estudio y para el control de 1 ± 1.10. La progresión por escala ampliada del estado de discapacidad, la tasa anualizada de brotes antes del tratamiento, la edad de inicio de la enfermedad, tiempo de evolución de la enfermedad y lesiones que realzan gadolinio se asociaron de forma significativa con la razón de ventaja de mayor probabilidad de no progresión para el grupo estudio con respecto al grupo control por la variable combinada progresión por escala ampliada del estado de discapacidad y brotes. Conclusiones: se identificaron indicadores precoces de respuesta al tratamiento con el interferón beta-1a, que ayudan a valorar la respuesta al tratamiento de forma precoz, lo que repercute de forma positiva en la evolución de la enfermedad.


ABSTRACT Background: multiple sclerosis modifying drugs are intended to reduce the frequency of relapses, delay the progression of disability, as well as the appearance of new lesions in the Central Nervous System. Objective: to determine the early indicators of response to treatment with IFNb-1a. Methods: Observational, analytical longitudinal prospective cohort study in patients diagnosed with multiple sclerosis. Two study cohorts were formed, each with 39 patients. Results the mean and standard deviation of the expanded disability status scale at 36 months was 2.37 ± 1.86 in the study group and 3.15 ± 2.1 in the control group. In the outbreaks of .13 ± .33 in the study group and in the control group of .41 ± .59. New lesions in T2 after the first 12 months of treatment was 0.90 ± 1.16 for the study group and 1 ± 1.10 for the control. Extended-scale progression of disability status, pretreatment annualized relapse rate, age of disease onset, time since disease progression, and gadolinium-enhancing lesions were significantly associated with the odds ratio of older Probability of non-progression for the study group with respect to the control group for the combined variable progression by extended disability status scale and relapses. Conclusions: early indicators of response to treatment with interferon beta-1a were identified; that help assess the response to treatment early, which has a positive impact on the evolution of the disease.

ABSTRACT

INTRODUCTION: Relapses are a hallmark of multiple sclerosis, being a characteristic feature of relapsing-remitting multiple sclerosis (RRMS). The occurrence of a relapse constitutes a source of significant discomfort that impacts all domains of daily life of patients with multiple sclerosis (PwMS). In this study we first explored the psychometric properties of the Spanish version of the Fear of Relapse Scale (FoR) in a sample of patients with RRMS. Besides, we explored the relationship between the Fear of Relapse Scale with fatigue and cognitive perceived deficits in our PwMS sample. METHODS: An online cross-sectional survey was conducted on 173 MS patients from 12 Spanish-speaking countries (Argentina, Mexico, Uruguay, Dominican Republic, Spain, Cuba, Colombia, Guatemala, Chile, Paraguay, Peru, and El Salvador). Confirmatory factor analysis (CFA) was performed to assess the factor structure of the scale. Multiple linear regression was used to evaluate the effects of health self-perception, fatigue, and perceived cognitive deficits over fear of relapse. RESULTS: The three-factor model in the CFA yielded a good model fit (χ2/df = 2.25, P < .001, RMSEA = .078, CFI = .91). McDonalds' Omega of the FoR (Spanish version) was .91. There was a statistically significant inverse correlation between FoR and health self-perception, and a positive correlation between FoR, fatigue, and perceived cognitive deficits. Finally, level of fatigue was a predictor of fear of relapse. CONCLUSIONS: The Spanish version of the Fear of Relapse Scale is a valid and reliable instrument to explore the experience of fear of relapse in patients with RRMS.

ABSTRACT

Introducción: El tratamiento de la esclerosis múltiple remitente-recurrente ha evolucionado significativamente en los últimos años con el descubrimiento de nuevas moléculas eficaces como tratamiento de mantenimiento. Por otro lado, el tratamiento de los brotes de esta enfermedad se basa clásicamente en corticoides, y en los casos refractarios a esta terapia se utiliza plasmaféresis. Presentamos un caso de esclerosis múltiple remitente-recurrente tratada periódicamente con una terapia que se ha utilizado clásicamente para los brotes: plasmaféresis. Caso clínico: Mujer de 39 años con esclerosis múltiple remitente-recurrente de inicio en el posparto, gran carga lesional y curso agresivo, en quien, ante una respuesta subóptima a terapias modificadoras de la enfermedad (alemtuzumab y ocrelizumab), se decide iniciar un tratamiento combinado junto con plasmaféresis periódicas ambulatorias cada tres semanas como tratamiento de mantenimiento. Se constata una buena tolerancia a esta terapia y evolución, y se produce estabilidad clínica. No ha requerido nuevos ingresos hospitalarios por brotes desde febrero de 2020 a marzo de 2021. Conclusión: Aunque es necesario que se realicen más estudios, este caso ofrece información sobre un potencial tratamiento de mantenimiento para pacientes con esclerosis múltiple remitente-recurrente refractaria a terapias con fármacos modificadores de la enfermedad.(AU)


Introduction: Relapsing-remitting multiple sclerosis (RRMS) treatment has significantly changed in recent years because of the discovery of new molecules that have shown efficacy as maintenance treatment. However, the classical treatment for acute attacks is based on corticosteroids administration, being the periodical plasmapheresis the alternative treatment in the case of refractory patients. We introduce a case of relapsing-remitting multiple sclerosis treated with a classical acute attacks therapy: plasmapheresis. Case report: The case of a 39-year-old patient who was diagnosed with relapsing-remitting multiple sclerosis, postpartum debut and aggresive course, who, after suboptimal response to disease modifying therapies (alemtuzumab and ocrelizumab), receives combination treatment with outpatient periodic plasmapheresis every 3 weeks as maintenance therapy. Good tolerance and response. Clinical stability with this treatment. She has not required new hospital admissions for acute attacks of multiple sclerosis from February 2020 to March 2021. Conclusion: Although more specific studies are needed, this case provides information on a potential new maintenance treatment for patients with relapsing-remitting multiple sclerosis refractory to disease-modifying drug therapies.(AU)

Objetivo: caracterizar desde el punto de vista epidemiológico, clínico e imagenológico los pacientes con diagnóstico de esclerosis múltiple remitente-recurrente en Villa Clara durante el periodo enero 2014 a diciembre 2020. Métodos: se realizó un estudio descriptivo, transversal, con enfoque cuantitativo en pacientes atendidos en la consulta multidisciplinaria de esclerosis múltiple del Hospital Universitario Clínico-Quirúrgico "Arnaldo Milián Castro" de Villa Clara. Se utilizaron métodos teóricos, empíricos y matemático-estadísticos. Resultados: se apreció que 57 pacientes fueron mujeres y 66 caucásicos. La edad de debut de la enfermedad para ambos grupos es 39,71 ± 9,86 años. Los años de evolución de la enfermedad muestran una media con desviación estándar de 9,77 ± 5,36 años. Las manifestaciones clínicas iniciales fueron: motor, sensitivo y neuritis óptica. En cuanto al número de lesiones detectadas por neuroimágenes fue de 11.58 ± 1.59. Presentaron presencia de bandas oligoclonales y síntesis de IgG para un 57.7 % y 83.3 % en toda la muestra de estudio respectivamente. Conclusiones: se caracterizó multidisciplinariamente a los pacientes lo que posiciona los resultados como novedosos en el entorno nacional e internacional; se aportan datos relevantes en aras de incrementar los conocimientos e información actualizada acerca de la enfermedad referida en Villa Clara.


ABSTRACT Background: there is no nationally representative scientific information on multiple sclerosis, an important aspect not only for epidemiological control, but also updating improvement in terms of medical education and in relation to management projects, due to the high cost the treatment of the disease generates. Objective: to characterize from the epidemiological, clinical and imaging point of view the patients diagnosed with relapsing-remitting multiple sclerosis in Villa Clara from January 2014 to December 2020. Methods: a descriptive, cross-sectional study with a quantitative approach was carried out in patients treated at the multidisciplinary consultation for multiple sclerosis of the "Arnaldo Milián Castro" Clinical-Surgical University Hospital in Villa Clara. Theoretical, empirical and mathematical-statistical methods were used. Results: it was observed that 57 patients were women and 66 Caucasian. The age of onset of the disease for both groups is 39.71 ± 9.86 years. The years of evolution of the disease show a mean standard deviation of 9.77 ± 5.36 years. The initial clinical manifestations were: motor, sensory and optic neuritis. Regarding the number of lesions detected by neuroimaging, it was 11.58 ± 1.59.

ABSTRACT

Objetivo: Dimetilfumarato es un fármaco autorizado en el tratamientode la esclerosis múltiple recurrente-remitente. El objetivo es evaluar laseguridad y persistencia del dimetilfumarato en la práctica clínica, y analizar la evolución de las linfopenias en pacientes en tratamiento con dimetilfumarato un mínimo de 6 meses.Método: Estudio observacional, longitudinal, retrospectivo entre agostode 2015 y marzo de 2019. Se incluyeron todos los pacientes en tratamiento durante un periodo mínimo de 6 meses. Se recogieron los datosde recuento linfocitario a diferentes tiempos: pretratamiento, a los 3, 6,12 meses y al final del periodo de estudio. Como modelo estadístico seutilizó la regresión logística para analizar la evolución de las linfopenias.Se estudió la relación entre el descenso del recuento linfocitario los primeros 6 meses de tratamiento y el desarrollo a tiempo final del estudio delinfopenias grado II/III que podrían ser motivo de suspensión. Además, seevaluaron otros indicadores de seguridad: reacciones adversas, suspensiones y abandonos de tratamiento. Para el análisis de la persistencia secontabilizaron los meses transcurridos desde el inicio hasta la suspensióndel tratamiento.Resultados: Se incluyeron 55 pacientes. El 80% fueron mujeres. Lasreacciones adversas más frecuentes fueron: linfopenia (27), rubefacción(16), molestias digestivas (11), fatiga (9), cefalea (3) y alteraciones delsueño (2). Durante el periodo considerado hubo 11 abandonos/suspensiones de tratamiento, las razones fueron: embarazo (2), decisión propia(2), infección por virus John Cunningham (1), alergia al fármaco (2) ylinfopenia (4). La mediana de duración de tratamiento fue de 23 meses(4-43 meses). (AU)


Objective: Dimethyl fumarate is a medication approved for the treatmentof relapsing-remitting multiple sclerosis. The purpose of the study was toevaluate the safety and persistence of dimethyl fumarate in clinical practice and analyze the occurrence of lymphopenia is patients treated withdimethyl fumarate over a period of at least 6 months.Method: This is a retrospective longitudinal observational study carriedout between August 2015 and March 2019. The study cohort was madeup of patients who had been treated with dimethyl fumarate for at least6 months. Lymphocyte counts were recorded at different points of time(pre-treatment, at 3, 6, 12 months, and at the end of the study period). Theevolution of lymphopenia was evaluated by means of a logistic regressionstatistical model. An analysis was performed of the relationship betweena decreased lymphocyte count over the first 6 months of treatment andthe development, by the end of the study, of grade II-III lymphopenianecessitating discontinuation of dimethyl fumarate. Other safety indicatorswere also evaluated including adverse events and interruptions or discontinuations of treatment. Persistence was determined by measuring the timeto discontinuation of treatment.Results: The study included a total of 55 patients, of whom 80% werefemale. The most common adverse events were lymphopenia (27), rubefaction (16), digestive symptoms (11), fatigue (9), headache (3) and sleepdisturbances (2). Eleven subjects interrupted/discontinued their treatment during the study period; reasons were as follows: pregnancy (2), personal decision (2), John Cunningham virus infection (1), allergy to the drug(2), and lymphopenia (4). Median duration of treatment was 23 months(4-43 months). A statistically significant association was found betweena lower lymphocyte count over the first 6 months of treatment and thedevelopment of severe lymphopenia by the end of the study [OR = 1.34(1.27-11.41); 95% CI (p = 0.001)]. )(AU)

ABSTRACT

INTRODUCTION: At present, there is a lack of economic assessments of second-line treatments for relapsing-recurring multiple sclerosis. The aim of this study was to compare the efficiency between fingolimod and natalizumab in Spain. METHODS: A cost minimisation analysis model was developed for a 2-year horizon. The same relapse rate was applied to both treatment arms and the cost of resources was calculated using Spain's stipulated rates for 2012 in euros. The analysis was conducted from the perspective of Spain's national health system and an annual discount rate of 3% was applied to future costs. A sensitivity analysis was performed to validate the robustness of the model. RESULTS: Indirect comparison of fingolimod with natalizumab revealed no significant differences (hazard ratio between 0.82 and 1.07). The total direct cost, considering a 2-year analytical horizon, a 7.5% discount stipulated by Royal Decree, and a mean annual relapse rate of 0.22, was € 40914.72 for fingolimod and € 45890.53 for natalizumab. Of the total direct costs that were analysed, the maximum cost savings derived from prescribing fingolimod prescription was € 4363.63, corresponding to lower administration and treatment maintenance costs. Based on the sensitivity analysis performed, fingolimod use was associated with average savings of 11% (range 3.1%-18.7%). CONCLUSIONS: Fingolimod is more efficient than natalizumab as a second-line treatment option for relapsing-remitting multiple sclerosis and it generates savings for the Spanish national health system.
