Alemtuzumab improves quality-of-life outcomes compared with subcutaneous interferon beta-1a in patients with active relapsing-remitting multiple sclerosis.

BACKGROUND: Alemtuzumab was superior on clinical and magnetic resonance imaging (MRI) outcomes versus subcutaneous interferon beta-1a in phase 3 trials in patients with relapsing-remitting multiple sclerosis. OBJECTIVE: To examine quality-of-life (QoL) outcomes in the alemtuzumab phase 3 trials. METHODS: Patients who were treatment naive (Comparison of Alemtuzumab and Rebif® Efficacy in Multiple Sclerosis I [CARE-MS I]) or had an inadequate response to prior therapy (CARE-MS II) received annual courses of alemtuzumab 12 mg/day at baseline (5 days) and Month 12 (3 days) or subcutaneous interferon beta-1a 44 µg three times/week. QoL was measured every 6 or 12 months using Functional Assessment of Multiple Sclerosis (FAMS), European Quality of Life-5 Dimensions (EQ-5D) and its visual analog scale (EQ-VAS), and 36-Item Short-Form Survey (SF-36). RESULTS: Statistically significant improvements from baseline with alemtuzumab were observed on all three QoL instruments at the earliest post-baseline assessment and sustained through Year 2. Statistically significant greater QoL improvements over subcutaneous interferon beta-1a were seen at all time points in CARE-MS II with FAMS, EQ-VAS and SF-36 physical component summary, and in CARE-MS I with FAMS. CONCLUSION: Patients treated with alemtuzumab had improvements in physical, mental, and emotional QoL regardless of treatment history. Improvements were significantly greater with alemtuzumab versus subcutaneous interferon beta-1a on both disease-specific and general measures of QoL.

A review of the effects of baclofen and of THC:CBD oromucosal spray on spasticity-related walking impairment in multiple sclerosis.

INTRODUCTION: Multiple sclerosis (MS) is a complex disease with a heterogeneous and unpredictable clinical course. Mobility impairment after progressive paralyses and muscle tone spasticity is common. Areas covered: The prevalence, assessment, and pharmacological management of gait impairment and spasticity in MS and their effects on health-related quality of life (HRQoL) are discussed. The roles of oral and intrathecal baclofen and of delta-9-tetrahydrocannabinol/cannabidiol (THC:CBD) oromucosal spray in treating MS spasticity-related gait impairment are reviewed. Expert commentary: Mobility impairment and spasticity are experienced by approximately 90% and 80% of MS patients, respectively, during the disease course. Prevalence and severity of gait impairment and spasticity increase as disease progresses. The symptoms are related and both impact negatively on HRQoL. Oral baclofen and tizanidine are generally used for first-line treatment of MS spasticity but are ineffective in approximately 40% of cases. Second-line therapy includes add-on THC:CBD spray for patients with resistant MS spasticity. Results of studies evaluating baclofen for treating MS spasticity gait impairment are equivocal. In studies of patients with resistant MS spasticity, THC:CBD spray consistently improved the timed 10-meter walk test and significantly improved multiple spatial-temporal and kinematic gait parameters. THC:CBD oromucosal spray warrants further investigation as a treatment for MS spasticity-related gait impairment.

Fingolimod Use for the Treatment of Multiple Sclerosis in a Clinical Practice Setting in Madrid.

OBJECTIVE: To assess the effectiveness and safety of fingolimod use in a Spanish clinical practice setting. METHODS: Retrospective study with multiple sclerosis patients who received at least 1 fingolimod dose between January 2004 and January 2015. Effectiveness and safety data were collected during the entire treatment of each patient. Analysis was performed for the total population and stratified according to prior treatment, sex, and age at treatment initiation. RESULTS: A total of 167 patients were included, 50.9% had prior immunomodulator use, 33.5% natalizumab use, and 15.6% were naive patients. The annual relapse rate (ARR) decreased for the total population at month 12 (62%) and month 24 (84%) (P < 0.0001, in both cases); for naive patients (P < 0.05) and patients with prior immunomodulator use (P < 0.0001); for patients with prior natalizumab use, the ARR kept low after treatment initiation (0.23). After 24 months, the proportion of relapse-free patients was 70% or greater and disability progression-free patients was 80% or greater. No significant differences were observed when the results were compared by prior treatment, sex, or age. Thirty-two patients (19.2%) reported adverse drug reactions and 9.6% discontinued: 4.8% due to adverse drug reactions and 4.8% for lack of effectiveness. CONCLUSIONS: The results support fingolimod use due to clinical effectiveness, tolerability, and ease of administration.

A consensus initiative for the assessment of patients newly diagnosed with multiple sclerosis in Spain: the eXamina Project.

AIM: To create a national consensus checklist to assess newly diagnosed multiple sclerosis patients when considering treatment initiation in Spain. MATERIALS & METHODS: The Delphi consensus method was used. A scientific committee drafted items/domains, 52 experts evaluated their inclusion in the project checklist and 47 experts assessed checklist use in clinical practice. RESULTS: Forty-eight items from seven dimensions were selected: sociodemographics, n = 3; medical history, n = 10; multiple sclerosis clinical factors, n = 14; laboratory/MRI, n = 8; multiple sclerosis signs affecting treatment, n = 4; multiple sclerosis signs affecting management, n = 1; treatment-related features, n = 8. Understanding, acceptance, ease of use, effectiveness and suitability of checklist use were favorably rated by ≥75.5% of experts. CONCLUSION: This project provides a consensus checklist gathering necessary information when considering multiple sclerosis treatment in newly diagnosed patients.

Biomarkers in multiple sclerosis: an update for 2014.

Multiple sclerosis is a chronic, demyelinating and inflammatory disease of the central nervous system that mainly affects young adults. It is characterised by processes involving inflammation, demyelination and axonal destruction, and as a result the pathogenic aspects and response to treatment of the disease vary widely. It is therefore difficult to establish a prognosis for these patients or to determine the effectiveness of the different drugs that are employed. Current clinical research into the development of new biomarkers has advanced a great deal in recent years, especially in the early stages of the disease. Yet, it is essential to further our knowledge about novel markers of the disease, and not only in the more advanced stages, so as to be able to stop disability from progressing and to establish new therapy regimens in these patients. This review presents an update on the information available about the biomarkers that are currently validated and used in multiple sclerosis, together with the possible candidates for utilisation in routine clinical practice.

[Monoclonal antibodies for the treatment of multiple sclerosis]. / Anticuerpos monoclonales para el tratamiento de la esclerosis múltiple.

Until the mid 1990s, with the appearance of interferon beta and glatiramer acetate, there was no treatment for multiple sclerosis (MS). However, due to their moderate therapeutic potential in some patients, a broad search was continued to find new and more effective treatment strategies, largely concentrated on monoclonal antibodies (MOAB). Natalizumab, the first MOAB for the treatment of MS, was approved at the end of 2004, representing a major advance in the field of neuroimmunology. Today, there is broad experience with natalizumab and other MOAB (alemtuzumab, daclizumab, rituximab, ocrelizumab, ofatumumab and anti-lingo-1) that are pending commercialization or are under phase II or III of development with promising results. The present review analyzes the efficacy and safety results of all these drugs.

Review of the novelties presented at the 29th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) (III).

The most relevant data presented at the 29th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS), held in October 2013 in Denmark, were summarised at the sixth edition of the Post-ECTRIMS Expert Meeting held in Madrid in October 2013, resulting in this review, which is being published in three parts. This third part of the Post-ECTRIMS review discusses the effects of immunomodulatory therapy on the natural history of multiple sclerosis, with special attention to the assessment of long-term effects and the use of historical controls as an alternative to randomised trials compared with placebo. This article contains possible future therapeutic strategies to be tested in experimental models and discusses clinical trials that are underway and future treatments. It also summarises the results of recent studies of disease-modifying treatments and developments in symptom management. Briefly, on the horizon are many drugs with different mechanisms of action, although new strategies and treatment algorithms are needed, as are new biomarkers and assessment measures of secondary progression and long-term records to assess safety. As for the symptomatic treatment of the disease, the proposal is a personalised treatment plan and a multidisciplinary approach to improve the quality of life of patients.

Esta tercera parte de la revision Post-ECTRIMS aborda los efectos del tratamiento inmunomodulador en la historia natural de la esclerosis multiple, con especial atencion a la valoracion del efecto a largo plazo y al uso de controles historicos como alternativa a los estudios aleatorizados comparados con placebo. Este articulo recoge posibles estrategias terapeuticas futuras que pasan por los modelos experimentales, y expone los ensayos clinicos en marcha y futuros tratamientos. Asimismo, resume los resultados de los ultimos estudios de los tratamientos modificadores de la enfermedad y las novedades en el manejo sintomatico. Brevemente, en el horizonte, hay muchos farmacos con diferentes mecanismos de accion, aunque son necesarias nuevas estrategias y algoritmos terapeuticos, biomarcadores y nuevas medidas de evaluacion de la progresion secundaria, y registros a largo plazo para evaluar la seguridad. En cuanto al tratamiento sintomatico de la enfermedad, se apuesta por un plan personalizado de tratamiento y una aproximacion multidisciplinar, de cara a mejorar la calidad de vida de los pacientes.

[Review of the novelties presented at the 29th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) (II)].

The most relevant data presented at the 29th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS), held in October 2013 in Denmark, were summarised at the sixth edition of the Post-ECTRIMS Expert Meeting, held in Madrid in October 2013, resulting in this review, which is being published in three parts. This second part of the Post-ECTRIMS review focuses on diagnostic imaging and differential diagnosis, the clinical and paraclinical monitoring of neurodegeneration, progression and disability, and functional imaging and neural connectivity. It is clear that conventional multiple sclerosis sequences remain essential for the diagnosis, differential diagnosis and disease monitoring, that new MRI techniques help to assess the neurodegenerative process, and that some of the new sequences are more specific to neuroaxonal injury. Very high field magnetic resonance imaging allows better understanding of the lesion load, distribution and heterogeneity of the lesions, and positron emission tomography studies offer new insight into the patho-physiology of the disease. Functional imaging and neural connectivity studies show that there is cortical reorganisation in multiple sclerosis, whose equilibrium with structural damage is responsible for the impairment.

Esta segunda parte de la revision Post-ECTRIMS se centra en la imagen del diagnostico y diagnostico diferencial, en la monitorizacion clinica y paraclinica de la neurodegeneracion, progresion y discapacidad, y en la imagen funcional y conectividad neural. Queda patente que las secuencias convencionales de esclerosis multiple siguen siendo basicas para el diagnostico, el diagnostico diferencial y el seguimiento de la enfermedad, que las nuevas tecnicas de resonancia magnetica ayudan a evaluar el proceso de neurodegeneracion, y algunas de las nuevas secuencias son mas especificas del daño neuronal-axonal. La resonancia magnetica de campo muy alto permite un mejor conocimiento de la carga lesional, distribucion y heterogeneidad de las lesiones, y los estudios con tomografia por emision de positrones ofrecen una nueva vision de la fisiopatologia de la enfermedad. Los estudios de imagen funcional y conectividad neural muestran que en la esclerosis multiple existe una reorganizacion cortical cuyo equilibrio con el daño estructural es responsable de la discapacidad.

[Biomarkers in multiple sclerosis]. / Biomarcadores en esclerosis múltiple.

Multiple sclerosis is the most frequent disabling neurological disease in young adults. Its development includes independent processes of inflammation, demyelination, neurodegeneration, gliosis and repair, which are responsible for the heterogeneity and individual variability in the expression of the disease, its prognosis and response to treatment. As part of personalised medicine, the progress made in the search for new biomarkers has identified promising candidates that may be useful for the early diagnosis of the disease, for detecting prognostic and developmental profiles of the disease, and for monitoring the response to treatment. Unfortunately, few of them have been validated adequately, which prevents them from being applied in clinical practice. In view of the latest findings, the experts recommend orienting research in another direction, not so much towards the discovery of new molecules or imaging techniques, but instead towards a clinical validation of these markers, with the aim of fostering translational research. This review offers an update on the information about the biomarkers in multiple sclerosis that have currently been validated and are thus potential candidates, as well as looking at their value in the diagnosis, prognosis, evaluation of the development of the disability caused by the disease and the response to therapy.

Review of the novelties presented at the 28th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) (III).

The most significant data presented at the 28th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS), held in France in October 2012, have been summarised in the fifth edition of the Post-ECTRIMS Experts Meeting, held in Madrid in October 2012. This led to the drafting of this review, which has been published in three parts. This third part of the Post-ECTRIMS review presents the findings from the latest studies conducted with disease-modifying treatments, more specifically with glatiramer acetate, laquinimod, ponesimod, BG-12, teriflunomide, daclizumab, natalizumab and secukinumab (AIN457). Likewise, we also address the reasons that justify the search for innovative treatments for multiple sclerosis, with antigen-specific therapy, cell therapy and therapy aimed at promoting remyelination being highlighted among other future therapeutic strategies. Access to new pharmacological agents and the complexity of the therapy of multiple sclerosis in the future will require new design strategies and directions in clinical trials, including the use of surrogate markers, new statistical applications, superiority, inferiority or equivalence clinical trials and adaptable designs.

Asimismo, se abordan las razones que justifican la busqueda de tratamientos innovadores para la esclerosis multiple, destacando la terapia antigenoespecifica, la terapia celular y la terapia dirigida a promover la remielinizacion entre las futuras estrategias terapeuticas. La disponibilidad de nuevos farmacos y la complejidad de la futura terapia de la esclerosis multiple necesitan nuevas direcciones y estrategias de diseño en los ensayos clinicos, entre ellas el uso de marcadores subrogados, nuevas aplicaciones estadisticas, ensayos clinicos de superioridad, inferioridad o equivalencia, y diseños adaptables.

Review of the novelties presented at the 28th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) (I).

The most relevant data presented at the 28th edition of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS), held in October 2012 in France, have been summarized in the fifth edition of the Post-ECTRIMS Expert Meeting held in Madrid in October 2012. The present review summarizes the views and results of the meeting and is being published in three parts. This first part of the Post-ECTRIMS review addresses the incidence and prevalence of multiple sclerosis (MS), which has increased at the global level, largely due to the increased incidence in women because the risk of developing the disease is increased in females, with minimal concurrent effect on the progression of MS. Sexual dimorphism is evident in MS, and all evidence points to an interaction between hormonal, genetic, and environmental factors. The paediatric population represents an ideal group to study susceptibility factors to the disease, which is why collaborative studies designed to increase the patient samples are being considered, given its low prevalence. In this review, inflammatory and neurodegenerative phenomena involved in the pathogenesis of the disease and that have a cause-and-effect or shared relationship with the disease are being discussed. Current hypotheses suggest a phenomenon of compartmentalization, presumably inaccessible to current immunomodulatory therapy. Among the possible mechanisms involved in these processes of inflammation and demyelination, the role of Th17 cells, mitochondrial dysfunction, early disruption of astrocytic processes, and chronic hypoxia are discussed.

Esta primera parte de la revision Post-ECTRIMS aborda la incidencia y prevalencia de la esclerosis multiple (EM), que, en el ambito mundial, ha aumentado a expensas de las mujeres, ya que el sexo femenino aumenta el riesgo de desarrollar la enfermedad, aunque no afecta de forma negativa a su evolucion. El dimorfismo sexual en la EM es evidente, y todo apunta a una interaccion entre factores hormonales, geneticos y medioambientales. La poblacion pediatrica representa un grupo idoneo para el estudio de factores de susceptibilidad a la enfermedad, razon por la que se estan planteando estudios colaborativos ideados para aumentar la muestra de pacientes, dada su baja prevalencia. En esta revision se discute sobre los fenomenos inflamatorios y de neurodegeneracion que intervienen en la patogenia de la enfermedad, y que probablemente esten relacionados, bien de forma compartida o como causa efecto. Las hipotesis actuales apuntan a un fenomeno de compartimentacion presumiblemente inaccesible a la terapia inmunomoduladora actual. Entre los posibles mecanismos involucrados en estos procesos de inflamacion y desmielinizacion se discute el papel de las celulas Th17, disfuncion mitocondrial, disrupcion precoz de procesos astrocitarios e hipoxia cronica.

Review of the novelties presented at the 27th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) (II).

The new insights presented at the 5th Joint Triennial Congress of the European and Americas Committees on Treatment and Research in Multiple Sclerosis (ECTRIMS and ACTRIMS) held in Amsterdam, the Netherlands, 19-22 October 2011, have been summarized at the fourth edition of Post-ECTRIMS meeting held in Madrid in November 2011. Regional grey-matter atrophy is more sensitive to cognitive impairment than global grey-matter atrophy measures. In patients with clinically isolated syndrome cognitive impairment does not predict conversion to multiple sclerosis (MS) after 5-years of follow-up. Focusing on central nervous system plasticity and functional reorganization in MS, an early intervention can improve clinical aspects and enhances brain plasticity. Preservation of a potential for plasticity provides a rationale for rehabilitation interventions even in later stages of disease. Therapeutical strategies have focused on stem cell-mediated remyelination and immunomodulation functions, on cellular infiltration into the brain, and on new ways for immuno-modulation for the development of future therapies in MS. Encouraging findings from clinical trials with current and emerging disease-modifying therapy being developed was also a key theme at this edition. Positive results have been reported for rituximab, ocrelizumab, ofatumumab, daclizumab, alemtuzumab, teriflunomide, BG-12, and laquinimod, including a favorable safety profile. Since armamentarium for the treatment of MS is fast increasing, concerns exist about the risk of severe adverse events with their use. This aspect reinforces the importance of disease registries as a proactive tool for monitoring drug safety in the post-approval setting.

Review of the novelties presented at the 27th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) (I).

The new insights presented at the 5th Joint Triennial Congress of the European and Americas Committees on Treatment and Research in Multiple Sclerosis (ECTRIMS and ACTRIMS) held in Amsterdam, the Netherlands, 19-22 October 2011, have been summarized at the fourth edition of Post-ECTRIMS meeting held in Madrid in November 2011. Further evidence from epidemiological studies yield a possible relationship between nutrition and alterations of the microbiota that may result in the development of multiple sclerosis (MS) and that may trigger the exacerbation of disease symptoms. Also show the magnitude of impact of comorbidities in multiple sclerosis course as well as the impact of early identification and management. Review of current data on chronic cerebrospinal venous insufficiency and MS sclerosis concludes that there is no role of chronic cerebrospinal venous insufficiency in either multiple sclerosis risk or MS severity. New diagnostic criteria for MS have simplified requirements for demonstrating dissemination of lesions in time. High-field magnetic resonance imaging improves cortical visualization and become a promising tool to detect remyelinization and cortical and medullary lesions, and optical coherence tomography is established as a powerful tool for neuroprotection trials. Diffuse meningeal inflammation through B-cell follicle-like structures is associated with cortical pathology and an accelerated clinical course in secondary progressive MS sclerosis. Systemic inflammation may contribute to neurodegeneration processes in MS, and with regard to grey matter damage recent findings conclude that occurs early in disease course, and correlates with future MS-related disability.

Clinical response to methylphenidate in a patient with self-induced photosensitive epilepsy.

The classification of epilepsy includes a group of generalized idiopathic epilepsies that are triggered by a specific mode of activation, known as reflex epilepsies. Photosensitive epilepsy is the most common type. Some patients with photosensitive epilepsy use this sensitivity to induce seizures or epileptiform discharges on the electroencephalogram. In some patients, psychopharmacological treatment, for instance with selective serotonin reuptake inhibitors and neuroleptics, has demonstrated benefit insofar as self-induction of seizures is concerned. However, so far as we know, there are no documented cases of treatment with methylphenidate in patients with this type of seizure. Our purpose is to report the case of an 8-year-old girl with attention-deficit hyperactivity disorder (ADHD) and self-induced photosensitive epilepsy whose behavior in general, and self-inducing behavior in particular, improved dramatically following treatment with methylphenidate.

[Spanish multi-centre observational study of the first attacks suggestive of multiple sclerosis: the PREM cohort]. / Estudio observacional multicentrico espanol de primeros episodios sugestivos de esclerosis multiple: cohorte PREM.

INTRODUCTION: Recent studies have shown the need to optimise the management of patients after a first attack suggestive of multiple sclerosis (MS). Our aim is to determine whether the results from follow-ups in these studies are reproducible within a Spanish multi-centre context. PATIENTS AND METHODS: The PREM study (observational prospective Spanish multi-centre study at 24 months) included patients in the first three months following a first event suggestive of MS with at least two typical lesions in a magnetic resonance scan. The Expanded Disability Status Scale (EDSS) was obtained and the presence of attacks was evaluated basally and at 3, 6, 9, 12, 18 and 24 months; a magnetic resonance scan was performed basally and at 6 and 24 months so as to be able to calculate the brain volume and the volumes of the lesions (T1, T2 and T1 after administering gadolinium). McDonald and Poser criteria were evaluated during the follow-up. A subgroup of patients was followed up for a total period of four years. RESULTS: Altogether 110 patients (67% females) with a mean age of 30.2 years were included in the study; 22 patients dropped out of the study before it finished. Poser criteria were met by 19% and 45% of patients at 6 months and 24 months, respectively; 63% and 71% satisfied McDonald criteria. The EDSS decreased significantly (-0.94; p < 0.001) and development of atrophy was observed (-1.2%; p < 0.001) at 24 months. CONCLUSIONS: Results of the follow-up of patients with first attacks suggestive of MS within a Spanish multi-centre context are wholly comparable with those from international clinical trials performed in these patients.

[Review of the novelties presented at the 26th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) (I)]. / Revision de las novedades presentadas en el XXVI Congreso del Comite Europeo para el Tratamiento e Investigacion en Esclerosis Multiple (ECTRIMS) (I).

The new insights presented at European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS), held in the city of Gothenburg, Sweden, in October 2010, have been summarized at the third edition of Post-ECTRIMS meeting held in Madrid in November 2010. The age is an important factor related to the course and prognosis of multiple sclerosis (MS). The evolution to progressive disease persists more than 50 years after diagnosis of MS and a reduction in the delay of diagnosis has been detected. Several strategies have been proposed in order to improve the efficacy of magnetic resonance regarding prognosis and course of disease. The studies presented at the Congress reflect the influence of gender on course and severity of disease symptoms, showing an increase of worldwide prevalence of MS in women. Neuroprotective action of estrogen receptor beta has been reported. The genome wide association studies have allowed investigators to identify numerous susceptible alleles. In this regard, HLA class II genes, seems to contribute to genetic risk for developing neutralizing antibodies against beta-interferon. Vitamin D deficiency and Epstein-Barr virus have been highlighted as risk factors for MS in the reported findings. On the subject of the ongoing controversy regarding the role of inflammation and degeneration in MS, several arguments have been found to support the role of CNS autoimmunity to explain the presence of inflammatory phenomenon. The available data hold the potential therapeutic role of mesenchymal cells given the involvement of these stem cells in CNS repair.

Fetal alcohol syndrome, Tourette syndrome, and hyperactivity in nine adopted children.

Much attention has been paid in recent years to the role of prenatal exposure to alcohol. Fetal alcohol syndrome is one of the most severe afflictions resulting from such exposure. The present report documents the cases of adopted children diagnosed with fetal alcohol syndrome who developed both Tourette syndrome and attention deficit-hyperactivity disorder. Out of a population of 138 adopted children with behavior issues whose clinical histories were reviewed retrospectively, 9 children (6.5%) presented this constellation. Epidemiologic data, clinical data, neurologic examination findings, complementary testing, and developmental data were recorded. All nine patients studied had initial psychomotor retardation, despite the frequent case of subsequent intelligence quotient normalization. From a behavioral perspective, half of the cases presented obsessive-compulsive disorder and problems with social relations. Aggressive behavior was common. These cases also presented a high degree of severity of both tics and hyperactivity. The most common drug treatment was methylphenidate. This constellation of fetal alcohol syndrome, Tourette syndrome, and attention deficit-hyperactivity disorder is scantly reported in the literature and is likely underdiagnosed. This particular constellation poses its own prognosis and requires its own treatment.

Schizencephaly: pre- and postnatal magnetic resonance imaging.

Schizencephaly is a rare disorder of neuronal migration that is characterized by the presence of clefts that extend from the ependymal surface of the lateral ventricles to the pial lining of the cortex. The authors present the case of a female patient with a prenatal diagnosis made by magnetic resonance imaging (MRI), her clinical course, and neurorradiological evolution following birth. A 6-year-old female, with right open lip schizencephaly, was diagnosed by means of prenatal cerebral magnetic resonance at the gestational age of 25 weeks. The patient does not present intellectual disability, reaching developmental mile-stones at normal time points. The MRI of the brain reveals right, perisylvian, closed lip schizencephaly. Prenatal MRI is remarkably useful in the diagnosis and prognostic approach to the condition. It is less useful in classifying the unilateral forms (open vs closed lips), and hence, its prognostic validity is more limited.

Anticuerpos monoclonales para el tratamiento de la esclerosis múltiple / Monoclonal antibodies for the treatment of multiple sclerosis

Hasta mediados de los años noventa, con la aparición del interferón beta y el acetato de glatirámero, no existía tratamiento para la esclerosis múltiple (EM). Sin embargo, debido a su moderado potencial terapéutico en algunos pacientes, se continuó con una amplia búsqueda encaminada a encontrar nuevas y más efectivas estrategias de tratamiento, centrando buena parte de los esfuerzos en los anticuerpos monoclonales (AcMo). A finales de 2004 fue aprobado natalizumab, el primer AcMo para el tratamiento de la EM, que representó un importantísimo avance en el campo de la neuroinmunología. Hoy en día, la experiencia con natalizumab es amplia y existen otros AcMo (alemtuzumab, daclizumab, rituximab, ocrelizumab, ofatumumab y anti-lingo-1) pendientes de comercializar, o en fases II y II de estudio con resultados prometedores. En esta revisión se analizan los resultados de eficacia y seguridad de todos ellos (AU)

Multiple sclerosis is a chronic, demyelinating and inflammatory disease of the central nervous system that mainly affects young adults. It is characterised by processes involving inflammation, demyelination and axonal destruction, and as a result the pathogenic aspects and response to treatment of the disease vary widely. It is therefore difficult to establish a prognosis for these patients or to determine the effectiveness of the different drugs that are employed.
