RESUMEN

Introducción: La esclerosis múltiple afecta principalmente a mujeres en edad fértil, y el período de gestación y posparto es de especial interés por las peculiaridades que comporta en cuanto a evolución de la enfermedad y por las consecuencias terapéuticas que se derivan. En el período de lactancia materna (LM), la elección de la estrategia de tratamiento debe poner en una balanza, por un lado, los beneficios bien establecidos de la LM para el recién nacido y su madre y, por el otro, el perfil de seguridad y potenciales efectos adversos en el lactante derivados de la exposición a los fármacos modificadores de la enfermedad, por transferencia a través de leche materna. Desarrollo: Se realiza una revisión de la evidencia actual acerca de la seguridad de los fármacos modificadores de la enfermedad disponibles para el tratamiento de la esclerosis múltiple durante el período de LM, y se recogen datos de transferencia de los diferentes fármacos a la leche materna, así como los potenciales efectos adversos descritos en el lactante. Los fármacos considerados de primera elección durante este período son el interferón beta y el acetato de glatiramer. El resto de los fármacos modificadores de la enfermedad no están aceptados para su utilización en el período de LM por ficha técnica. Sin embargo, en los últimos años, se han publicado datos de estudios de práctica clínica y series de casos que indican que algunos de estos fármacos podrían utilizarse con seguridad durante este período. Conclusiones: Teniendo en cuenta los beneficios reconocidos de la LM para la salud tanto de la madre como del lactante, se debe recomendar la LM exclusiva a las pacientes con esclerosis múltiple siempre que sea posible. Es fundamental realizar una evaluación individualizada previa al embarazo y valorar las diferentes opciones de tratamiento en función de cada paciente.(AU)


Introduction: Multiple sclerosis mainly affects women of childbearing age, and the pregnancy and postpartum period is of special interest because of the peculiarities of the disease course and the therapeutic consequences that derive from it. During the period of breastfeeding (BF), the choice of treatment strategy must weigh up the well-established benefits of BF for both the newborn and the mother against the safety profile and potential adverse effects on the infant resulting from exposure to disease-modifying drugs transferred through breast milk. Development: The study reviews the current evidence on the safety of disease-modifying drugs available for the treatment of multiple sclerosis during the BF period, and gathers data on the transfer of the different drugs into breast milk, as well as the potential adverse effects described in the infant. The drugs of first choice during this period are interferon beta and glatiramer acetate. The rest of the disease modifying drugs are not accepted for use in the BF period according to their summary of product characteristics. However, in recent years, data from studies of clinical practice and case series have been published suggesting that some of these drugs could be used safely during this period. Conclusions: Given the recognised health benefits of BF for both mother and infant, exclusive breastfeeding is recommended whenever possible. It is essential to carry out an individualised assessment prior to pregnancy and to evaluate the different treatment options depending on each patient.(AU)

RESUMEN

La neuritis óptica (NO) tiene como principales causas la esclerosis múltiple (EM), las enfermedades dentro del espectro de la neuromielitis óptica (NMOSD) y la enfermedad asociada a anticuerpos contra la proteína de la mielina del oligodendrocito, también conocida como MOGAD. Cuando todo el cribado es negativo, podemos hablar de NO idiopática, aunque este diagnóstico deberá ser provisional. La NO se puede diagnosticar clínicamente y no se requieren de forma rutinaria pruebas paraclínicas para confirmarla. Sin embargo, pruebas como la resonancia magnética (RM), los potenciales evocados visuales (PEV) y la tomografía de coherencia óptica (OCT) pueden dar soporte al diagnóstico si la presentación clínica es atípica. El uso de nuevas secuencias de RM, la OCT, los PEV multifocales y la determinación de neurofilamentos han posibilitado el uso de la NO como modelo de remielinización y neuroprotección, propiciando la realización de ensayos clínicos de fase II. Algunos de estos fármacos, como el opicinumab, la clemastina, la fenitoína o la simvastatina, han obtenido resultados positivos; no obstante, su efecto clínico está por definir. Se acepta que los corticoides no mejoran el pronóstico a largo plazo de la NO, aunque algunos estudios retrospectivos sugieren que existe una ventana terapéutica desde el inicio de los síntomas. La plasmaféresis también ha demostrado eficacia en pacientes con NO. En esta revisión abordaremos aspectos básicos del manejo de la NO, en el contexto fundamental de la EM, la NMOSD y la MOGAD, haciendo hincapié en las novedades etiopatogénicas, diagnósticas, pronósticas y terapéuticas.(AU)


The main causes of optic neuritis (ON) are multiple sclerosis (MS), neuromyelitis optica spectrum disorder (NMOSD) and myelin oligodendrocyte glycoprotein antibody disease, also known as MOGAD. When all screening is negative, we can speak of idiopathic ON, although this diagnosis should be provisional. ON can be diagnosed clinically and paraclinical tests are not routinely required to confirm it. However, tests such as magnetic resonance imaging (MRI), visual evoked potentials (VEP) and optical coherence tomography (OCT) can lend support to the diagnosis if the clinical presentation is atypical. The use of new MRI sequences, OCT, multifocal VEPs and the determination of neurofilaments has allowed ON to be used as a model for remyelination and neuroprotection, leading to phase II clinical trials. Some of these drugs, such as opicinumab, clemastine, phenytoin or simvastatin, have shown positive results; however, their clinical effect remains to be defined. It is accepted that corticosteroids do not improve the long-term prognosis of ON, although some retrospective studies suggest that there is a therapeutic window from the onset of symptoms. Plasmapheresis has also been shown to be effective in patients with ON. In this review we will address basic aspects of the management of ON, in the fundamental context of MS, NMOSD and MOGAD, with emphasis on etiopathogenic, diagnostic, prognostic and therapeutic developments.(AU)

RESUMEN

BACKGROUND AND PURPOSE: Both optical coherence tomography (OCT) and magnetic resonance imaging (MRI) volumetric measures have been postulated as potential biomarkers of multiple sclerosis (MS)-related disability. The aim of the study was to investigate the association between OCT and brain volume and spinal cord area (SCA) parameters in patients with relapsing MS and to assess their independent associations with disability. METHODS: This was a cross-sectional analysis of 90 patients with MS who underwent OCT and MRI examination. Values of peripapillary retinal nerve fibre layer (pRNFL), ganglion cell/inner plexiform layer (GCIPL) and inner nuclear layer of eyes without previous optic neuritis were obtained. SCA and brain parenchymal fraction (BPF), grey and white matter fractions were obtained. Multivariable regression analyses were conducted with disability as dependent variable. RESULTS: Lower pRNFL thickness and lower GCIPL volume as well as lower BPF, grey matter fraction and SCA were associated with a longer disease duration and a higher Expanded Disability Status Scale score. Lower pRNFL thickness and GCIPL volumes were associated with lower BPF and SCA. In the multivariable logistic regression analyses, pRNFL thickness and GCIPL volume outperformed MRI in predicting disability. CONCLUSIONS: The OCT measures correlate with brain and spinal cord atrophy and appear more closely associated with disability than MRI volumetric measures.

RESUMEN

BACKGROUND AND PURPOSE: Gray matter pathology is known to occur in multiple sclerosis and is related to disease outcomes. FreeSurfer and the FMRIB Integrated Registration and Segmentation Tool (FIRST) have been developed for measuring cortical and subcortical gray matter in 3D-gradient-echo T1-weighted images. Unfortunately, most historical MS cohorts do not have 3D-gradient-echo, but 2D-spin-echo images instead. We aimed to evaluate whether cortical thickness and the volume of subcortical structures measured with FreeSurfer and FIRST could be reliably measured in 2D-spin-echo images and to investigate the strength and direction of clinicoradiologic correlations. MATERIALS AND METHODS: Thirty-eight patients with MS and 2D-spin-echo and 3D-gradient-echo T1-weighted images obtained at the same time were analyzed by using FreeSurfer and FIRST. The intraclass correlation coefficient between the estimates was obtained. Correlation coefficients were used to investigate clinicoradiologic associations. RESULTS: Subcortical volumes obtained with both FreeSurfer and FIRST showed good agreement between 2D-spin-echo and 3D-gradient-echo images, with 68.8%-76.2% of the structures having either a substantial or almost perfect agreement. Nevertheless, with FIRST with 2D-spin-echo, 18% of patients had mis-segmentation. Cortical thickness had the lowest intraclass correlation coefficient values, with only 1 structure (1.4%) having substantial agreement. Disease duration and the Expanded Disability Status Scale showed a moderate correlation with most of the subcortical structures measured with 3D-gradient-echo images, but some correlations lost significance with 2D-spin-echo images, especially with FIRST. CONCLUSIONS: Cortical thickness estimates with FreeSurfer on 2D-spin-echo images are inaccurate. Subcortical volume estimates obtained with FreeSurfer and FIRST on 2D-spin-echo images seem to be reliable, with acceptable clinicoradiologic correlations for FreeSurfer.

RESUMEN

We aimed to single out multiple sclerosis (MS) cases with poor outcome after natalizumab withdrawal and to identify predictive variables. We ascertained 47 withdrawals, and compared their pre- and post-natalizumab periods. We objectively defined significant clinical worsening after natalizumab withdrawal as a 2-step increase in Expanded Disability Status Scale (EDSS). We performed regression models. As a group, post-natalizumab annualized relapse rate (ARR) was lower in the post-natalizumab period, and there were no differences in the mean number of gadolinium (Gd)-enhancing lesions between pre- and post-natalizumab magnetic resonance imaging (MRI). Corticosteroid treatment did not change the outcomes. Eight patients (19%) presented significant clinical worsening after natalizumab withdrawal, which was predicted by a higher baseline EDSS and a 1-step EDSS increase while on natalizumab.

RESUMEN

BACKGROUND: A pseudoatrophy effect has been held responsible for the lack of net impact of natalizumab on brain volume outcomes in 2-year trials, but no data are available beyond 24 months. OBJECTIVE: We aimed to investigate brain volume dynamics in natalizumab-treated patients in up to 3 years after therapy initiation with clinical correlations. METHODS: Patients on natalizumab for at least 3 years were clinically assessed 3-monthly. Magnetic resonance imaging scans were performed at baseline and yearly. Brain volume changes were obtained with SIENA. Multivariate models were used to investigate the association between baseline inflammation and changes in brain volume and disability. RESULTS: Sixty-two patients with multiple sclerosis were analysed. Mean age and disease duration were 34.7 (SD: 8.3) and 10.4 (SD: 6.6) years. Presence of gadolinium enhancement at baseline was not associated with Expanded Disability Status Scale changes (p=0.468), but was associated with larger brain volume decreases (p=0.005) in the first (p=0.024) and second year (p=0.019) but not in the third year (p=0.863). Brain volume changes at 12 and 36 months were marginally associated with disability status at month 12 (p=0.094) and 36 (p=0.084), respectively. CONCLUSIONS: Baseline inflammation affects brain volume measures up to 24 months after natalizumab initiation. A marginal association of brain volume changes with disability is present.

RESUMEN

Recent studies have suggested a role of the cation channel TRPM4 in mediating neurodegeneration in experimental autoimmune encephalomyelitis and multiple sclerosis (MS). We aimed to extrapolate central nervous system findings to the blood compartment by determining TRPM4 expression in peripheral blood mononuclear cells from 12 healthy controls (HC) and 64 untreated MS patients. TRPM4 mRNA expression levels were comparable between HC and MS patients with primary progressive MS (n=17), secondary progressive MS (n=19), and relapsing-remitting MS during clinical remission (n=21) and relapses (n=7). These findings do not support a role of TRPM4 in the peripheral blood compartment of MS patients.

RESUMEN

BACKGROUND: Sialic acid binding immunoglobulin-like lectins (Siglecs) are cell surface receptors that recognize sialic acids and may attenuate immune responses and reduce inflammation. OBJECTIVE: The purpose of this study was to investigate the role of two members of the Siglec family, SIGLEC1 and SIGLEC7, in the clinical course and disease activity of patients with multiple sclerosis (MS). METHODS: SIGLEC1 and SIGLEC7 expression was determined by flow cytometry in the blood monocytes of 16 healthy controls and 55 untreated MS patients (13 primary progressive MS (PPMS) patients, 13 secondary progressive MS (SPMS) patients and 29 relapsing-remitting MS (RRMS) patients (18 during clinical remission and 11 during relapse)). RESULTS: SIGLEC1 expression by CD14+ monocytes was significantly increased in MS patients compared with controls (p=0.025 for percentage of positive cells; p=0.007 for mean fluorescence intensity (MFI)). Stratification of patients into different clinical forms revealed increased SIGLEC1 expression in patients with progressive forms of the disease, particularly in those with PPMS (p=0.003 for percentage of positive cells and p=0.001 for MFI when compared with controls; p=0.031 for percentage of positive cells when compared with RRMS patients). Both inflammatory and resident monocytes contributed to the increase in SIGLEC1 expression observed in PPMS patients. SIGLEC7 expression was significantly up-regulated in blood monocytes from RRMS during relapse compared with patients during clinical remission (p=0.001 for MFI). CONCLUSIONS: These findings suggest roles for SIGLEC1 in the chronic progressive phases of MS and for SIGLEC7 in acute disease activity.

RESUMEN

BACKGROUND: Despite the availability of diagnostic criteria, an overlap between neuromyelitis optica (NMO) and multiple sclerosis (MS) exists, particularly in the early stage of the disease. OBJECTIVE: To study the value of NMO-immunoglobulin G (IgG) determination in Caucasian patients with a first demyelinating episode who develop a relapsing form of optic neuritis or myelitis. METHODS: This study was based on a prospectively acquired cohort of patients regarded as having a clinically isolated syndrome (CIS) at the time of presentation. From this cohort, 2 different groups were selected: group 1 (NMO phenotype), consisting of a first attack involving the optic nerve or the spinal cord, and at least a second event affecting either topography, and group 2 (negative control group), consisting of a first attack involving the brainstem or the cerebral hemispheres and at least 1 relapse in any topography. Group 3 was composed of patients with NMO according to the 2006 revised diagnostic criteria. Serum NMO-IgG was determined by indirect immunofluorescence. RESULTS: A total of 3.1 of the group 1 patients were positive for NMO-IgG in comparison to 3.9% of group 2 and 44.5% of group 3, NMO. One of the positive patients in group 1 evolved to NMO. CONCLUSIONS: NMO-IgG determination is crucial in detecting patients who will develop NMO; however, its value as a routine test in cases presenting with symptoms of the type seen in MS is low, and should only be performed in those patients in which the initial diagnosis is not clear.

RESUMEN

Introducción: El manejo del tratamiento antitrombótico tras una hemorragia intracerebral (HIC) en pacientes anticoagulados no está bien definido. Analizamos los riesgos y beneficios de la antiagregación (AG) frente al reinicio de la anticoagulación con antagonistas de la vitamina K (AVK) en una serie de pacientes. Material-métodos: Estudio retrospectivo de HIC en pacientes anticoagulados. Se registraron datos demográficos, antecedentes de hipertensión arterial, tiempo de seguimiento y nuevo evento vascular cerebral (HIC, infarto cerebral [IC]).Resultados: Se evaluó a 88 pacientes, de edad media 69±9 años, 50% varones, 73% hipertensos. Durante la fase aguda fallecieron 18 pacientes y el seguimiento se perdió en 31. De los restantes (n=39), se reinició AVK en 25 y se cambió a AG en 14. Comparando las características de ambos grupos, el grupo anticoagulado era de menor edad (p=0,005) y las fuentes cardioembólicas eran con mayor frecuencia de alto riesgo (p=0,003). Tras un seguimiento promedio de 54±31 meses, la distribución de eventos fue: IC (grupo AVK 8%, grupo AG 14,3%, p=0,6); HIC (AVK 24%, AG 7.1%, p=0,38); IC o HIC (AVK 32%, AG 21,4%, p=0,48); muerte (AVK 29%, AG 7,1%, p=0,21). Esta tendencia de mayor riesgo de nuevos eventos en pacientes con AVK se confirmó mediante curvas de Kaplan-Meier, aunque sin significación estadística.Conclusiones: El reinicio del tratamiento con AVK tras una HIC en pacientes anticoagulados podría aumentar el riesgo de nuevos eventos hemorrágicos y la mortalidad. Son necesarios estudios prospectivos, para definir mejor el tratamiento antitrombótico idóneo tras una HIC relacionada con la anticoagulación (AU)


Introduction: The management of antithrombotic therapy after intracerebral hemorrhage (ICH) in anticoagulated patients is not well defined. We analyzed the risks and benefits of antiplatelet therapy (AG) against the resumption of anticoagulation with vitamin K antagonists (AVK) in a series of patients. Material and methods: Retrospective study of ICH in anticoagulated patients. We registered demographic data, history of hypertension (HT), time of follow-up and new cerebral vascular events (ICH, stroke [IC]).Results: We evaluated 88 patients, mean age 69±9 years, 50% men, 73% hypertensive. During the acute phase 18 patients died and the follow-up was lost in 31. Of the remaining (n=39), AVKs were resumed in 25 and changed to AG in 14. Comparing the characteristics of both groups, the anticoagulated group was younger (P=.005) and the embolic sources were more often of higher risk (P=.003). After an average follow-up of 54±31 months, the distribution of events was: IC (AVKs 8%, AG 14.3%, P=.6), ICH (AVKs 24%, AG 7.1%, P=.38), IC or ICH (AVKs 32%, AG 21.4%, P=.48) and death (AVKs 29%, AG 7.1%, P=.21). This trend of increased risk of new events in patients with AVKs was confirmed by Kaplan-Meier curves, although without statistical differences.Conclusions: Restarting AVK treatment after ICH in anticoagulated patients could increase the risk of new bleeding events and mortality. Prospective studies are needed to define a better and appropriate antithrombotic therapy after ICH related with anticoagulation (AU)

After an average follow-up of 54±31 months, the distribution of events was: IC (AVKs 8%, AG 14.3%, P=.6), ICH (AVKs 24%, AG 7.1%, P=.38), IC or ICH (AVKs 32%, AG 21.4%, P=.48) and death (AVKs 29%, AG 7.1%, P=.21). This trend of increased risk of new events in patients with AVKs was confirmed by Kaplan-Meier curves, although without statistical differences. CONCLUSIONS: Restarting AVK treatment after ICH in anticoagulated patients could increase the risk of new bleeding events and mortality. Prospective studies are needed to define a better and appropriate antithrombotic therapy after ICH related with anticoagulation.

RESUMEN

Introducción. La población inmigrante es cada vez más numerosa en la consulta neurológica. No está bien establecido si existen diferencias geográficas en la prevalencia de las cefaleas primarias y la posible influencia de la emigración. Pacientes y métodos. Estudio retrospectivo (12 meses) y prospectivo (18 meses) de las primeras visitas en la Unidad de Cefaleas del Hospital de la Santa Creu i Sant Pau. Identificamos el país de origen, parámetros temporales de la cefalea y de la inmigración, diagnósticos según criterios de la Sociedad Internacional de Cefaleas y tratamientos realizados. Se considera cefalea relacionada la que se inicia en el período de un año tras la inmigración. Resultados. La población inmigrante representa el 13,6% (n = 142) del total de las primeras visitas por cefalea (n = 1.044). Proceden principalmente de Latinoamérica (83,9%). La cefalea comenzó posteriormente a la inmigración en el 40,1% de los casos, sin existir relación temporal con la inmigración. La distribución de los diagnósticos de la cefalea son semejantes a los de la población autóctona; los más frecuentes son migraña (57,7%) y cefalea tensional (15,5%). Al comparar los tratamientos anteriores y posteriores a la inmigración, encontramos diferencias en el uso de triptanes (2,1% frente a 46,2%), ergotamina (9,8% frente a 2,1%) y utilización de tratamientos preventivos (2% frente a 45%). Conclusiones. La población inmigrante representa el 13% de las primeras visitas de cefalea y sus diagnósticos son similares a los de la población autóctona. El hecho de la emigración no es desencadenante ni agravante de la cefalea en nuestra serie. El tratamiento sintomático y preventivo difiere significativamente entre el período anterior a la inmigración y el posterior(AU)


Introduction. The immigrant population (IP) is visiting neurology departments on an increasingly more frequent basis. Research has still not made it clear whether there are geographical differences in the prevalence of primary headaches and the possible influence of emigration. Patients and methods. We conducted a retrospective (12 months) and prospective study (18 months) of the first visits to the Headache Unit at the Hospital de la Santa Creu i Sant Pau. Data collected included the country of birth, time parameters of the headache and of the immigration, diagnoses according to the criteria of the IHS and treatments that had been used. Related headaches were considered to be those that began within one year of having immigrated. Results. The IP represents 13.6% (n = 142) of the total number of first visits because of headaches (n = 1044). Immigrants came mostly from Latin America (83.9%). Headaches began after immigration in 40.1% of cases without the existence of any temporal relation with immigration. The distribution of the diagnoses of headache is similar to those of the local population, the most frequent being migraine (57.7%) and tension-type headache (15.5%). On comparing treatments prior to and following immigration, we find differences in the use of triptans (2.1% versus 46.2%), ergotamine (9.8% versus 2.1%) and in the use of preventive treatments (2% versus 45%). Conclusions. The IP accounts for 13% of all first visits due to headaches and their diagnoses are similar to those of the local population. Emigration is neither a precipitating nor an aggravating factor for headaches in our series. There is a significant difference in symptomatic and preventive treatment between the period prior to immigration and afterwards (AU)

RESUMEN

INTRODUCTION: The immigrant population (IP) is visiting neurology departments on an increasingly more frequent basis. Research has still not made it clear whether there are geographical differences in the prevalence of primary headaches and the possible influence of emigration. PATIENTS AND METHODS: We conducted a retrospective (12 months) and prospective study (18 months) of the first visits to the Headache Unit at the Hospital de la Santa Creu i Sant Pau. Data collected included the country of birth, time parameters of the headache and of the immigration, diagnoses according to the criteria of the IHS and treatments that had been used. Related headaches were considered to be those that began within one year of having immigrated. RESULTS: The IP represents 13.6% (n = 142) of the total number of first visits because of headaches (n = 1044). Immigrants came mostly from Latin America (83.9%). Headaches began after immigration in 40.1% of cases without the existence of any temporal relation with immigration. The distribution of the diagnoses of headache is similar to those of the local population, the most frequent being migraine (57.7%) and tension-type headache (15.5%). On comparing treatments prior to and following immigration, we find differences in the use of triptans (2.1% versus 46.2%), ergotamine (9.8% versus 2.1%) and in the use of preventive treatments (2% versus 45%). CONCLUSIONS: The IP accounts for 13% of all first visits due to headaches and their diagnoses are similar to those of the local population. Emigration is neither a precipitating nor an aggravating factor for headaches in our series. There is a significant difference in symptomatic and preventive treatment between the period prior to immigration and afterwards.
