RESUMEN
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)
ABSTRACT
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)
