[Family planning in men and women with multiple sclerosis. Analysis of the Andalusian Registry (2018-2022)]. / Planificación familiar en hombres y mujeres con esclerosis múltiple. Análisis del Registro Andaluz (2018-2022).

INTRODUCTION: The Andalusian Registry of Pregnancies in patients with multiple sclerosis is the largest Spanish registry on multiple sclerosis (MS) and family planning. For the first time, it includes information on the fertility of men with MS. The influence of the use of a disease-modifying treatment (DMT) on the health of the foetus/newborn and the impact of breastfeeding on MS are also analysed. SUBJECTS AND METHODS: This is a multicentre, prospective and observational study. Recruitment of patients took place between December 2018 and December 2020. Women were followed up for one year after delivery. Altogether 100 women and 16 men were included, with a total of 103 newborn infants. RESULTS: The annualised relapse rate of the women with MS decreased significantly during pregnancy (from 0.23 to 0.065). A total of 11.2% of patients resorted to assisted reproductive techniques in order to conceive a child. No association was found between the use of a DMT at conception and/or pregnancy and the risk of miscarriage, prematurity or low birth weight. Over half the women with MS (54.2%) chose to breastfeed (26.7% of them while on a DMT). CONCLUSIONS: MS does not affect the fertility of men. Neither does the use of a DMT at the time of conception affect their fertility or their children's health. Assisted reproductive techniques did not have a negative impact on the course of MS. Breastfeeding is a common practice among women with MS and there is no evidence of positive or negative effects on disease progression.

TITLE: Planificación familiar en hombres y mujeres con esclerosis múltiple. Análisis del Registro Andaluz (2018-2022).Introducción. El Registro Andaluz de Embarazos en pacientes con esclerosis múltiple (EM) es el mayor registro español sobre EM y planificación familiar. Por primera vez se incluye información sobre la fertilidad de hombres con EM. También se analizan la influencia del uso de un tratamiento modificador de la enfermedad (TME) en la salud del feto o recién nacido y el impacto de la lactancia materna en la EM. Sujetos y métodos. Es un estudio observacional, prospectivo y multicéntrico. El reclutamiento de pacientes se hizo entre diciembre de 2018 y diciembre de 2020. El seguimiento de las mujeres tras el parto fue de un año. Se incluyó a 100 mujeres y 16 hombres, con un total de 103 recién nacidos. Resultados. La tasa anualizada de brotes de las mujeres con EM descendió durante el embarazo de forma significativa (de 0,23 a 0,065). Un 11,2% de los pacientes recurrieron a técnicas de reproducción asistida para conseguir la gestación. No se encontró relación entre el uso de un TME en la concepción y/o embarazo y el riesgo de aborto, prematuridad o bajo peso al nacer. El 54,2% de las mujeres con EM optaron por dar lactancia (el 26,7% de ellas usando un TME). Conclusiones. La EM no afecta a la fertilidad de los hombres. Tampoco influye en ésta, ni en la salud de sus hijos, el uso de un TME en el momento de la concepción. Las técnicas de reproducción asistida no impactaron negativamente en la evolución de la EM. La lactancia se impone como una práctica habitual entre las mujeres con EM y no se evidencian efectos positivos o negativos sobre la evolución de la enfermedad.

SARS-CoV-2 infection and seroprevalence in patients with multiple sclerosis.

INTRODUCTION: The effect of SARS-CoV-2 infection in patients with multiple sclerosis (MS) and the influence of disease-modifying therapies (DMT) for MS on COVID-19 are unknown. To date, patients with MS have not been shown to present greater risk of COVID-19 or more severe progression of the disease. METHODS: We performed a descriptive study of patients with MS presenting SARS-CoV-2 infection diagnosed with PCR. We analysed demographic, clinical, laboratory, and treatment variables in our sample. Presence of antibodies against the virus was also determined. RESULTS: Relapsing-remitting MS (RRMS) was the most frequent form of MS in our sample. Prognosis was unfavourable in 10.2% of patients, and was associated with older age and higher scores on the Expanded Disability Status Scale (EDSS). Seroprevalence of antibodies against SARS-CoV-2 was 83.3% in our sample. Development of antibodies was not associated with DMT, lymphocytopaenia, or any of the other variables analysed. CONCLUSIONS: The incidence of COVID-19 was slightly higher in our sample than in the general population in our province. Unfavourable prognosis was associated with older age and higher EDSS scores. DMT and lymphocytopaenia did not influence the clinical course of COVID-19. Seroprevalence of antibodies against the virus in our sample was similar to that reported for the general population with positive PCR results for the virus; the influence of specific DMTs could not be determined.

Infección por SARS-CoV-2 y seroprevalencia en pacientes con esclerosis múltiple / SARS-CoV-2 infection and seroprevalence in patients with multiple sclerosis

Introducción: El efecto de la infección por SARS-CoV-2 en los pacientes con esclerosis múltiple (EM) y la influencia de los tratamientos modificadores de la enfermedad (TME) es desconocida. Hasta el momento no se ha observado que los pacientes con EM tengan mayor riesgo de infección por COVID-19, ni peor curso evolutivo de la misma.MétodosEstudio descriptivo de pacientes con EM e infección por SARS-CoV-2 diagnosticada mediante PCR. Hemos analizado variables demográficas, clínicas, de laboratorio y de tratamiento en nuestra muestra. Se ha determinado la presencia de anticuerpos frente a SARS-CoV-2 en estos pacientes.ResultadosLa forma de esclerosis múltiple remitente recurrente (EMRR) fue la más frecuente en lo pacientes con EM e infección por COVID-19. El 10,2% presentó una evolución desfavorable, relacionada con una mayor edad y una Expanded Disability Status Scale (EDSS) más elevada. La seroprevalencia de anticuerpos frente a SARS-CoV-2 en nuestro estudio ha sido del 83,3%. El desarrollo de anticuerpos no está relacionado con el TME, la presencia de linfopenia u otros factores analizados.ConclusionesLa incidencia de COVID-19 ha sido ligeramente inferior a la de la población general de nuestra provincia. La evolución desfavorable se ha relacionado con una mayor edad y una puntuación elevada en la EDSS. El TME y la linfopenia no se han relacionado con el curso de la infección por COVID-19. La seroprevalencia es similar a la encontrada en población general con PCR positiva, sin poder determinar la influencia de los distintos TME. (AU)
