ABSTRACT

La mielitis transversa, de origen inflamatorio, es una afectación rara de la médula espinal que afecta a uno o varios niveles. La etiología incluye esclerosis múltiple, causas infecciosas o trastornos del espectro de la neuromielitis óptica. Se presenta de forma aguda, con síntomas motores, sensoriales y/o disautonómicos como los gastrointestinales y urinarios. El diagnóstico se basa en la sintomatología, evolución y se confirma por punción lumbar, resonancia magnética nuclear y analítica sanguínea completa. Se presenta el caso clínico de una paciente con mielitis transversa, que debutó con sintomatología gastrointestinal, síntomas motores y confirmación diagnóstica con resonancia magnética nuclear.


Inflammatory transverse myelitis is a rare condition that affects one or more levels of the spinal cord. Its etiology includes multiple sclerosis, infectious causes, or disorders within the spectrum of neuromyelitis optica. It presents acutely with motor, sensory, and/or dysautonomic symptoms, such as those related to the gastrointestinal and urinary systems. Diagnosis is based on symptomatology, evolution, and is confirmed by lumbar puncture, magnetic resonance imaging, and complete blood analysis. We present a clinical case of a patient with transverse myelitis who presented with gastrointestinal symptoms, motor symptoms, and was diagnosed with magnetic resonance imaging.

ABSTRACT

La presente es una revisión bibliográfica actualizada sobre el manejo de la Esclerosis Múltiple (EM), enfermedad neurológica progresiva de tipo desmielinizante más frecuente a nivel mundial. En Chile, su presentación remitente-recurrente (RRMS) es patología GES, por lo que se vuelve relevante para el médico general y estudiantes del área de la salud reconocer e identificar las terapias disponibles para el control de esta patología. Si bien la EM no es un cuadro frecuente, su sintomatología es alarmante e incapacitante, por lo que, con frecuencia, el primer acercamiento del paciente es a los servicios de urgencia, tornándose necesario contar con nociones básicas sobre el tratamiento y manejo. La presente revisión recopiló artículos publicados entre 2019 y 2023 de distintos motores de búsqueda con énfasis en el tratamiento farmacológico y no farmacológico de esta enfermedad. Además de describir el tratamiento convencional como la inmunomodulación, las terapias biológicas, el soporte con glucocorticoides y los fármacos remielinizantes, se abordan nuevas líneas de investigación prometedoras, como el rol inmunogénico de la microbiota intestinal, la capacidad epigenética de la dieta, estrategias de rehabilitación cognitiva y el potencial uso de cannabinoides para el manejo paliativo del dolor. Se concluye que un tratamiento oportuno con fármacos modificadores de la enfermedad, tanto de primera línea como de segunda, son imprescindibles para el manejo de la EM, sin embargo, la calidad de vida puede verse significativamente acrecentada por la incorporación de estrategias que se encuentran al alcance del médico general y que no requieren de derivación a nivel secundario.


This is an updated bibliographical review on the management of Multiple Sclerosis (MS), the most common progressive neurological disease of demyelinating disorders worldwide. In Chile, its relapsing-remitting presentation (RRMS) is a state-covered illness pathology, so it becomes relevant for the general practitioner and med students to recognize and identify therapies available for the control of this desease. Although MS is not a frequent condition, its symptoms are alarming and disabling, which is why, frequently, the first approach of the patient is to the emergency services, making it necessary to have basic knowledge about treatment and management. The present review compiled articles published between 2019 and 2023 from different search engines with an emphasis on the pharmacological and non-pharmacological treatment of the MS. In addition to describing conventional treatment such as immunomodulation, biological therapies, glucocorticoid support and remyelinating drugs, new promising lines of research are addressed, such as the immunogenic role of the intestinal microbiota, the epigenetic capacity of the diet, strategies on cognition rehabilitation and the potential use of cannabinoids for the palliative management of pain. It is concluded that the classic treatment with disease-modifying drugs, both first-line and second-line, are essential for the management of MS; however, quality of life can be significantly increased by incorporating strategies found at the reach of the general practitioner and do not require referral at a greater complexity center.

ABSTRACT

Abstract Background Studies were carried out with the objective of evaluating the quality of life (QoL) of patients affected by chronic inflammatory demyelinating polyradiculopathy (CIDP). However, the cognitive issue is still little addressed. Objectives To assess the QoL and cognitive impairment of patients with CIDP and to analyze whether there is a correlation between these parameters. Methods Seven patients with CIDP and seven paired controls were subjected to: mini-mental state examination (MMSE); Montreal cognitive assessment (MoCA); digit symbol replacement/symbol copy test (DSST); fatigue severity scale (FSS); Beck depressive inventory-I (BDI-I), and a short-form of health survey (SF-36). Results The mean age of the participants was 50 years (71.4% male). The MMSE and MoCA had no statistical difference between the groups. Patients showed superior results in the memory domain in the MoCA (5 vs. 2, p = 0.013). In the DSST, we observed a tendency for patients to be slower. There was a strong negative correlation between fatigue levels and vitality domain (SF-36). There was no significant correlation between depression levels and QoL, and there was no correlation between depression and the results obtained in the cognitive tests. The patients presented higher levels of depression (15.28 vs. 3.42, p < 0.001). A total of 57% had severe fatigue, 28.8% self-reported pain, and 57.1% complained of cramps. Conclusion There was no cognitive impairment in these patients. However, there was a tendency of slower processing speed. To better evaluate the alterations found, a study with a larger number of individuals would be necessary. Chronic inflammatory demyelinating polyradiculopathy affects the QoL of patients in different ways.


Resumo Antecedentes Estudos foram realizados com o objetivo de avaliar a qualidade de vida (QV) de pacientes acometidos pela polirradiculopatia desmielinizante inflamatória crônica (PDIC). No entanto, a questão cognitiva ainda é pouco abordada. Objetivos Avaliar a QV e o comprometimento cognitivo em pacientes com PDIC bem como se existe correlação entre esses parâmetros. Métodos Sete pacientes com PDIC e sete controles pareados foram submetidos a: miniexame do estado mental (MEEM); avaliação cognitiva de Montreal (MoCA); teste de substituição de símbolo de dígito/cópia de símbolo (DSST); escala de gravidade da fadiga (FSS);Beck depressive inventory-I (BDI-I) e um short-form of health survey (SF-36). Resultados A média de idade dos pacientes foi de 50 anos (71,4% do sexo masculino). O MMSE e o MoCA não apresentaram diferença estatística entre os grupos. Os pacientes apresentaram resultados superiores no domínio memória do MoCA (5 vs. 2, p = 0,013). No DSST, observamos uma tendência de os pacientes serem mais lentos. Houve forte correlação negativa entre os níveis de fadiga e o domínio vitalidade (SF-36). Não houve correlação significativa entre níveis de depressão e QV. Não houve correlação entre depressão e os resultados obtidos nos testes cognitivos. Níveis elevados de depressão foram observados nos pacientes (15,28 vs. 3,42, p < 0,001). Um total de 57% apresentou fadiga intensa, 28,8% dor autorreferida, e 57,1% queixam-se de câimbras. Conclusão Não há comprometimento cognitivo nos pacientes estudados. Observamos somente uma tendência de lentificação na velocidade de processamento. Para melhor avaliar as alterações encontradas, será necessário estudo com um número maior de indivíduos. A PDIC afeta de diferentes formas o nível de QV de seus portadores.

ABSTRACT

La neuroinmunología es una disciplina que cada vez amplía más sus horizontes en la comprensión de las enfermedades neurológicas. Contemporáneamente, y a la luz de los nexos fisiopatológicos de las enfermedades neurológicas y la inmunología, se han planteado enfoques diagnósticos y terapéuticos específicos. A pesar de los importantes avances de esta disciplina, existen múltiples dilemas que le conciernen y se filtran en la práctica clínica. En esta revisión, se presentan y discuten 15 controversias, las cuales se construyen con la información clínica disponible más actualizada. Los temas incluidos son: disminución de esteroides en recaídas de esclerosis múltiple; recomendaciones terapéuticas en esclerosis múltiple a la luz de la pandemia por el SARS-CoV-2; evidencia de vacunación en esclerosis múltiple y en otras enfermedades desmielinizantes; panorama actual del síndrome clínico y radiológico aislado; y fallas terapéuticas en esclerosis múltiple; además, criterios para suspender las terapias modificadoras de la enfermedad; evidencia del manejo en recaídas leves; recomendaciones para la profilaxis contra Strongyloides stercolaris; utilidad de un segundo ciclo de inmunoglobulina en el síndrome de Guillain-Barré; criterios para diferenciar una polineuropatía crónica desmielinizante inflamatoria de inicio agudo de un síndrome de Guillain-Barré y, utilidad de la enzima convertidora de angiotensina en neurosarcoidosis. En cada una de las controversias, se presenta la problemática general y se ofrecen recomendaciones específicas que pueden adoptarse en la práctica clínica diaria.


Neuroimmunology is a discipline that increasingly broadens its horizons in the understanding of neurological diseases. At the same time, and in front of the pathophysiological links of neurological diseases and immunology, specific diagnostic and therapeutic approaches have been proposed. Despite the important advances in this discipline, there are multiple dilemmas that concern and filter into clinical practice. This article presents 15 controversies and a discussion about them, which are built with the most up-to-date evidence available. The topics included in this review are: steroid decline in relapses of multiple sclerosis; therapeutic recommendations in MS in light of the SARS-CoV-2 pandemic; evidence of vaccination in multiple sclerosis and other demyelinating diseases; overview current situation of isolated clinical and radiological syndrome; therapeutic failure in multiple sclerosis, as well as criteria for suspension of disease-modifying therapies; evidence of the management of mild relapses in multiple sclerosis; recommendations for prophylaxis against Strongyloides stercolaris; usefulness of a second course of immunoglobulin in the Guillain-Barré syndrome; criteria to differentiate an acute-onset inflammatory demyelinating chronic polyneuropathy versus Guillain-Barré syndrome; and, the utility of angiotensin-converting enzyme in neurosarcoidosis. In each of the controversies, the general problem is presented, and specific recommendations are offered that can be adopted in daily clinical practice.

ABSTRACT

Abstract Background There is a lack of evidence of cognitive involvement in chronic inflammatory demyelinating polyneuropathy (CIDP) and, the reports about the involvement of the brain and central nervous system (CNS) are few and controversial. The Five Digit Test (FDT) evaluates processing speed (PS) and executive functions orally. Objective To evaluate the performance on the FDT of CIDP patients with and without CNS (brain/cerebellum) alterations observed on brain Magnetic Resonance Imaging (MRI) scans. Methods The Hospital Anxiety and Depression Scale (HADS, to assess neuropsychiatry symptoms), the Rasch-built Overall Disability Scale (R-ODS; to assess disability), and the FDT (to assess cognition) were applied to 14 CIDP patients and 24 age-matched healthy control subjects. The patients were submitted to routine brain MRI and, according to the results, they were divided into two groups: those with abnormalities on the MRI (CIDPabnl) and those with normal parameters on the MRI (CIDPnl). The FDT data of five CIDPnl patients and nine CIDPabnl subjects were analyzed. Comparisons between the groups were performed for each task of the FDT. Results We found statistical differences for both groups of CIDP patients in terms of PS, for the patients spent more time performing the PS tasks than the controls. The PS measures were negatively associated with disability scores (reading: r = −0.47; p = 0.003; counting: r = −0.53; p = 0.001). Conclusions Our data suggested the presence of PS impairment in CIDP patients. Disability was associated with slow PS.


Resumo Antecedentes Faltam evidências de envolvimento cognitivo na polineuropatia inflamatória desmielinizante crônica (PIDC), e há poucos e controversos estudos que tratam do envolvimento cerebral e do sistema nervoso central (SNC). O Teste dos Cinco Dígitos (Five Digit Test, FDT, em inglês) avalia a velocidade de processamento (VP) e as funções executivas oralmente. Objetivo Avaliar o desempenho no FDT de pacientes com PIDC com e sem alterações no SNC (cérebro/cerebelo) de acordo com o exame de imagem cerebral por ressonância magnética (RM). Métodos Ao todo, 14 pacientes e 24 controles saudáveis pareados por idade responderam a Escala Hospitalar de Ansiedade e Depressão (que avalia sintomas neuropsiquiátricos), a Escala de Incapacidade Geral elaborada pelo método Rasch (que avalia a incapacidade) e o FDT (que avalia a cognição). Os pacientes foram submetidos a RM cerebral e, de acordo com os resultados, divididos em dois grupos: aqueles com anormalidades (PIDCabnl) e aqueles sem alterações (PIDCnl) na RM. Cinco pacientes PIDCnl e nove PIDCabnl tiveram os dados analisados. Comparações entre os grupos foram realizadas para cada parte do FDT. Resultados Os dois grupos de pacientes foram estatisticamente mais lentos nas tarefas de VP comparados ao grupo controle. As medidas de VP foram negativamente associadas às pontuações de incapacidade (leitura: r = −0,47; p = 0,003; contagem: r = −0,53; p = 0,001). Conclusões Os dados indicaram a presença de prejuízo na VP em pacientes com PIDC. A incapacidade foi associada à lentidão na VP.

ABSTRACT

Resumen Introducción: las neuropatías periféricas comprenden una amplia gama de entidades que afectan uno o múltiples nervios periféricos en cualquiera de sus categorías funcionales. Métodos: revisión de la literatura sobre la temática, mediante la búsqueda de artículos en las bases de datos Pubmed y Google Scholar publicadas en los últimos 21 años, sin restricción idiomática, excluyendo estudios descriptivos y reportes de caso. Resultados: las neuropatías periféricas tienen una prevalencia del 2 % al 3 %, pueden ser causadas por etiologías infecciosas, enfermedades inflamatorias, inmunológicas, trastornos neoplásicos, exposición a tóxicos, fármacos y deficiencias nutricionales. El diagnóstico depende del juicio clínico. La aplicación de estudios de laboratorios y electrodiagnóstico pueden clasificar adecuadamente estas entidades. El tratamiento depende de la entidad subyacente y debe incluir un enfoque multimodal. Conclusiones: establecer estrategias de prevención, detección y tratamiento temprano permite una potencial recuperación y disminuye los costos para el sistema de salud.


Abstract Introduction: peripheral neuropathies comprise a wide range of entities affecting one or multiple peripheral nerves in any of their functional categories. Methods: review of the literature on the subject, by searching for articles in Pubmed and Google Scholar databases published in the last 21 years, without language restriction, excluding descriptive studies and case reports. Results: peripheral neuropathies have a prevalence of 2 % to 3 %, and can be caused by infectious etiologies, inflammatory diseases, immunological, neoplastic disorders, exposure to toxins, drugs and nutritional deficiencies. Their diagnosis depends on clinical judgment. The application of laboratory and electrodiagnostic studies can adequately classify these entities. Treatment depends on the underlying entity and should include a multimodal approach. Conclusions: establishing strategies for prevention, early detection and treatment allows for potential recovery and decreases costs for the health system.

ABSTRACT

Introducción: La polineuropatía desmielinizante inflamatoria crónica (CIDP) es una enfermedad desmielinizante e inflamatoria de mediación autoinmune. El tratamiento convencional es basado en la inmunomodulación e inmunosupresión. El uso de células madre es una terapia novedosa en los trastornos autoinmune, siendo incluida como terapia. Objetivo: Determinar la eficacia de la movilización de células madre mediante la aplicación del factor estimulador de colonias granulocíticas (F-ECG) en pacientes con CIDP que han recibido otras líneas de tratamiento. Material y Métodos: Se realizó un estudio aleatorizado, doble ciego sobre una cohorte de 45 pacientes con CIDP, donde se administró el (F-ECG) en 25 pacientes y 20 continuaron con el tratamiento habitual, tratados anteriormente con otras variantes terapéuticas por más de tres años, sin respuesta satisfactoria. Resultados: Predominio de los hombres para 64,4 por ciento, la Diabetes Mellitus tuvo mayor asociación y la medicación más usada fueron los esteroides. Los síntomas y signos clínicos mejoraron significativamente tras el tratamiento. Los valores de la puntuación del TCSS al mes y 3 meses después del tratamiento disminuyeron significativamente; pero este decremento no se mantuvo al final del estudio. La velocidad de conducción y el potencial de acción de los nervios sensoriales y motores mejoraron considerablemente después del tratamiento. Conclusiones: La efectividad de la aplicación del (F-ECG) para la mejoría de los síntomas clínicos y resultados de estudios neurofisiológicos evolutivamente son mayores que otras variantes terapéuticas en los primeros meses, con buena seguridad y tolerabilidad, por lo que se puede incluir en la terapéutica convencional para la CIDP(AU)


Introduction: Chronic inflammatory demyelinating polyneuropathy (CIDP) is an autoimmune demyelinating disease. Conventional treatment is based on immunomodulation and immunosuppression. The use of stem cells is a novel therapy in autoimmune disorders, so it is included as therapy. Objective: To determine the efficacy of mobilization of stem cells by applying granulocyte colony-stimulating factor (G-CSF) in patients with CIDP who have followed other lines of treatment. Material and Methods: A randomized, double-blind study was carried out on a cohort of 45 patients with CIDP. G-CSF was administered to 25 patients and 20 of them continued with the usual treatment. These patients were previously treated with other therapeutic variants for more than three years without satisfactory response. Results: There was a prevalence of men (64.4 percent), Diabetes Mellitus had a greater association, and the most used medications were steroids. Clinical symptoms and signs improved significantly after treatment. TCSS scores significantly decreased at one and three months after treatment, but this decrease was not maintained at the end of the study. The conduction velocity and action potential of sensory and motor nerves improved considerably after treatment. Conclusions: The effectiveness of the use of G-CSF shows an improvement of clinical symptoms. The results of neurophysiological studies have a better course than other therapeutic variants during the first months, with good safety and tolerability, so it can be included in the conventional therapy for the CIDP(AU)

ABSTRACT

RESUMEN El objetivo del estudio fue describir las características clínicas, la respuesta al tratamiento y posibles factores asociados de los pacientes con síndrome de Guillain Barré en el Instituto Nacional de Ciencias Neurológicas. Se realizó un estudio descriptivo sobre egresos hospitalarios durante el periodo 2017-2019. La respuesta al tratamiento se evaluó mediante la escala de discapacidad de Hughes. De los 31 pacientes el 61,3% eran varones, y la edad promedio fue de 50 años. Al ingreso, el 87,1% de pacientes se encontraban en el grado 3 o 4 de la escala de Hughes, la mayoría con compromiso axonal, el cual estuvo asociado a discapacidad. Solo 22 pacientes recibieron recambio plasmático; luego de seis meses el 90,9% disminuyó al menos en un grado en la escala de Hughes y el 42,8% quedaron sin discapacidad. En conclusión, se encontró un predominio del sexo masculino y del compromiso axonal, este último asociado a discapacidad.

ABSTRACT

Se describe el caso de una mujer de 35 años que presenta polineuropatía desmielinizante inflamatoria crónica como compromiso neurológico en su diagnóstico inicial de lupus eritematoso sistémico (LES). Si bien el compromiso neurológico es de una prevalencia variable en lupus, la asociación que se describe no es frecuente y tiene importantes connotaciones en el tratamiento.


We described a 35 years old female, who developed Chronic inflammatory demyelinating polyneuropathy as neurologic commitment during the early diagnosis in Systemic Lupus Erithematosus (SLE). While the neuropsychiatric commitment has a variable prevalence in SLE, the association that we describe is infrequent and it has important concerns during its treatment.

ABSTRACT

Chronic Inflammatory Demyelinating Polyneuropathy associated with hypoglycemia 2 to insulinoma is unusual, and to our knowledge, very few patients have been reported in literature. Despite varying presentations in these patients, the clinical characteristics are usually the same. The syndrome usually occurs after several episodes of protracted hypoglycemia. The neuropathy is nearly always symmetrical. We report anesthetic management for a young female patient presenting with CIDP & repeated hypoglycemic episodes during a 2-year period scheduled for insulinoma enucleation.


La polineuropatía desmielinizante inflamatoria crónica asociada con hipoglicemia secundaria a insulinoma es inusual y, hasta donde sabemos, muy pocos pacientes han sido reportados en la literatura. A pesar de las diferentes presentaciones en estos pacientes, las características clínicas suelen ser las mismas. El síndrome generalmente ocurre después de varios episodios de hipoglicemia prolongada. La neuropatía es casi siempre simétrica. Presentamos el manejo anestésico para una paciente joven que se presenta con polineuropatía desmielinizante inflamatoria crónica y episodios repetidos de hipoglicemia durante un período de 2 años programado para la enucleación de insulinoma.

ABSTRACT

La encefalomielitis diseminada aguda es una enfermedad desmielinizante del sistema nervioso central que generalmente se presenta como un trastorno monofásico asociado con síntomas neurológicos multifocales y encefalopatía. Suele ser precedido de una infección viral generalmente de vía aérea superior y, con menor frecuencia, de antecedente vaccinal. Se presenta un paciente de 4 años de edad con ataxia, encefalopatía, descenso progresivo del Score de Glasgow, imágenes de Sistema Nervioso Central compatibles con encefalomielitis diseminada aguda y adecuada respuesta al pasaje de pulsos de metilprednisolona. El objetivo de la publicación es enfatizar la presentación proteiforme de esta enfermedad y mejorar el reconocimiento de la misma en forma oportuna


The Acute Disseminated Encephalomyelitis is a demyelinating disease of the central nervous system that usually presents itself as a single-phase disorder associated with encephalopathy and multifocal neurologic symptoms. It tends to be preceded by a viral infection usually upper airway and, less frequently, of vaccinal antecedent. We present the case of a 4 years old child with clinic of ataxia, encephalopathy with progressive decline in Glasgow, history of fever in previous days, images of Central Nervous System compatible with ADEM and appropriate response to pulses of methylprednisolone. We decided to present this case to emphasize the varied presentation of this disease and improve recognition of it in a timely manner

ABSTRACT

RESUMEN El síndrome Clínico Aislado (SCA) denota al primer síntoma neurológico sugestivo de esclerosis múltiple (EM), de por lo menos 24 horas de duración; en ausencia de fiebre, procesos infecciosos y encefalopatía. Se caracteriza por su presentación frecuente en adultos jóvenes y afecta al nervio óptico, hemisferios cerebrales, tronco encefálico o médula espinal. La estratificación temprana del SCA es indispensable ya que con herramientas predictoras clínicas, radiológicas y biológicas, se puede establecer el riesgo de conversión a EM. El uso de terapias modificadoras de la enfermedad (TME) en el primer evento desmielinizante, ha demostrado retrasar la conversión de SCA a esclerosis múltiple en un 44 a 50 %. Sin embargo, no todos los pacientes con SCA evolucionarán a EM, por lo que el estudio de diversos marcadores prónosticos permitirá reconocer el escenario ideal donde los pacientes se beneficien del inicio temprano de TME.


SUMMARY Clinically Isolated Syndrome (CIS), denotes the first neurological symptom suggestive of Multiple Sclerosis (MS), at least 24 hours in duration; In the absence of fever, infectious processes and encephalopathy. It is characterized by its frequent presentation in young adults and affects the optic nerve, brainstem or spinal cord. The early stratification of CIS is essential because with clinical, radiological and biological predictors, the risk of conversion to MS can be established. The use of Disease Modifying Therapies (DMT) in CIS has been shown to delay the conversion of CIS to Multiple Sclerosis by 44 to 50 %%. However, not all patients with CIS will evolve to MS, so the study of several prognostic markers will allow to recognize the ideal scenario where patients benefit from the early onset of DMT.

ABSTRACT

El Síndrome de Guillain Barré (SGB) es una enfermedad inflamatoria desmielinizante aguda de probable etiología autoinmune, relacionada con diversos procesos infecciosos. Se caracteriza por debilidad muscular y disminución de los reflejos, pudiendo presentar un patrón clásico simétrico ascendente o con variables. La gravedad y pronóstico son variables, pudiendo comprometer los músculos torácicos derivando en insuficiencia respiratoria. Han sido descritos brotes endémicos asociados a diversos agentes infecciosos. Se presenta el reporte de 4 casos con el patrón más frecuente de SGB en los cuales se hizo el diagnóstico clínico confirmado por estudio del líquido cefalorraquídeo o electromiografía con progresión agresiva, 3 de ellos ameritando el traslado a unidad de terapia intensiva (UTI) para su tratamiento. Presentaron distintos factores de riesgo infecciosos como la suspensión de terapia antiretroviral y síntomas gastrointestinales, principalmente diarrea acuosa previo al debut de la paresia. Se implementó el tratamiento haciendo uso de plasmaféresis en uno de los casos e inmunoglobulina endovenosa en el resto con resultados variables. Se resalta la importancia del diagnóstico oportuno de esta patología ante la presencia de paresia y arreflexia con o sin patrón característico con la finalidad de atender la progresión de los mismos de forma adecuada, mejorar el pronóstico y evitar o disminuir las secuelas de los pacientes(AU)


Guillain Barré Syndrome (GBS) is an acute demyelinating inflammatory disease with probable autoimmune etiology related to diverse infectious processes. It is characterized by muscle weakness and diminished reflexes and may present an ascending symmetrical pattern or with other variables. The severity and prognosis are variable, and the thoracic muscles can be affected, resulting in respiratory failure. Endemic outbreaks associated with various infectious agents have been described. A report of 4 cases is presented in which the clinical diagnosis was confirmed by cerebrospinal fluid study or electromyography, with aggressive progression, 3 of them requiring to be transferred to the intensive care unit. The patients presented different infectious risk factors such as the interruption of anti-retroviral therapy and gastrointestinal symptoms, mainly watery diarrhea prior to the onset of the symptoms. The treatment was implemented using plasmapheresis in one of the cases and intravenous immunoglobulin in the rest with variable results. The importance of the timely diagnosis of this pathology in the presence of paresis and dimished reflexes with or without the characteristic pattern is highlighted in order to address the progression, appropriate management, improve the prognosis and avoid or reduce the sequelae of patients(AU)

ABSTRACT

Resumen La polineuropatía desmielinizante inflamatoria crónica (CIDP por sus siglas en inglés) corresponde a un espectro de diferentes fenotipos clínicos caracterizados por lesiones de naturaleza autoinmune, inflamatoria y desmielinizante, que afectan primariamente nervios periféricos y raíces nerviosas. Generalmente, los pacientes con CIDP presentan un curso crónico de discapacidad neurológica, pero hasta un tercio de los casos puede exhibir un curso remitente-recidivante. El fenotipo clásico involucra compromiso simétrico de la fuerza muscular y la sensibilidad proximal y distal, asociado a arreflexia generalizada. El diagnóstico requiere la demostración de la desmielinización de nervios mediante electromiografía o biopsia de nervios. Debido a la afectación de personas relativamente jóvenes, laboralmente activos, y a la gran discapacidad neurológica que puede generar, el tratamiento debiera ser iniciado precozmente. Los pilares de la terapia en su fase inicial son los corticoides intravenosos en altas dosis, inmunoglobulina intravenosa y la plasmaféresis, mientras que la terapia de mantención se basa, principalmente, en el uso de corticoides orales a bajas dosis. Este artículo presenta el caso de un paciente evaluado en nuestro hospital y diagnosticado con CIDP, y expone una revisión bibliográfica actualizada de la enfermedad.


Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) can be defined as a spectrum of different clinical phenotypes which are characterized by autoimmune, inflammatory and demyelinating injuries, primarily affecting the peripheral nerves and nerve roots. Most patients with CIDP have a chronic course of neurological disability, but about a third of cases exhibit a relapsing-remitting course. Classic phenotype of CIDP involves symmetric compromise of proximal and distal muscle strength and sensitivity, associated with generalized areflexia. For an accurate diagnosis, demonstration of nerve demyelination by electromyography or nerve biopsy is required. Due to the affectation of relatively young, labor-active people and the high risk for neurological disability by the disease, treatment should be initiated early. The predominant lines of therapy, in its initial phase, are high-dose intravenous corticosteroids, intravenous immunoglobulin and plasmapheresis, while the maintenance therapy is mainly based on low-dose oral corticosteroids. This article presents a case report of a patient evaluated in our hospital and diagnosed with CIDP and exposes an updated literature review about this disease.

ABSTRACT

La polineuropatía desmielinizante inflamatoria crónica (PDIC) se presenta generalmente con síntomas motores, debilidad tanto en los músculos proximales como en los distales con reflejos globalmente disminuidos o ausentes. La neuritis insulínica es un trastorno caracterizado por dolor agudo de las extremidades, y daño de los nervios periféricos con afectación predominante de las fibras pequeñas, en los pacientes diabéticos sometidos a un rápido control glucémico. El dolor es raro en la PDIC clásica. Describimos el caso de una mujer de 54 años con diabetes mellitus (DB) tipo II, en tratamiento reciente con insulina, que consultó por un cuadro de debilidad e hiperalgesia de los cuatro miembros de dos meses de evolución. Al examen físico presentaba dolor de intensidad 10/10 y alodinia en los cuatro miembros, a niveles proximal y distal, con fuerza muscular reducida de los músculos proximales y arreflexia patelar y aquilea bilateral. Se realizó un estudio electrofisiológico, el cual mostró una polineuropatía sensitiva y motora desmielinizante. Se indicó tratamiento con inmunoglobina humana recombinante, con total remisión del cuadro. Estudios realizados posteriormente demostraron positividad débil de los anticuerpos GM1, GD1a, GD1b y anti-asialo GM1. Previo al alta hospitalaria se recibieron los resultados de VDRL sérica positiva, y FTA-Abs. VDRL en líquido cefalorraquídeo fue negativa por lo que se descartó neurosífilis, indicándose tratamiento con penicilina benzatínica.


Chronic inflammatory demyelinating polyneuropathy (CIDP) is a disorder characterized by motor symptoms such as weakness in both proximal and distal muscles with globally diminished or absent reflexes. Insulin neuritis is referred as an acute pain in the extremities, due to the damage of peripheral nerves affecting mainly small fibers, in diabetic patients treated with insulin who achieved rapid glycemic control. Pain is unusual in classic CIDP. We report the case of a 54-year-old female patient with type II diabetes mellitus, and a recent onset of insulin therapy, who presented at the emergency room with a 2-month history of weakness and hyperalgesia of extremities. Physical examination showed marked pain and proximal and distal allodynia in the 4 limbs, with reduced muscle strength of the proximal muscles and patellar and achillear areflexia. Electrophysiological study showed sensory and motor polyneuropathy with a demyelinating predominance. Treatment with recombinant human immunoglobin was started, and the patient presented a total remission of the condition. Complementary studies confirmed weak serum positivity of GM1, GD1a, GD1b and anti-asialo GM1. Prior to hospital discharge, results of positive serum VDRL and FTA-Abs were received. VDRL in cerebrospinal fluid was negative, so neurosyphilis was ruled out, and treatment with benzathine penicillin was indicated.

ABSTRACT

Resumen La neuromielitis óptica (NMO) o enfermedad de Devic, es una enfermedad inflamatoria infrecuente del sistema nervioso central (SNC) que afecta predominantemente el nervio óptico y la médula espinal. El mecanismo de la enfermedad es dado por la producción de anticuerpos IgG cuyo principal blanco inmunitario es el canal acuaporina 4 (AQP4), los cuales desencadenan un proceso inflamatorio y desmielinizante en dichas estructuras. Presentamos el caso de una paciente, quien desarrolló episodios sensitivos crónicos fluctuantes con afección visual, sin mejoría con el tratamiento convencional; durante el abordaje diagnóstico se encontraron lesiones desmielinizantes y anticuerpos anti-AQP4 positivos, por lo que se concluyó el diagnóstico de NMO, y respondió de manera positiva al tratamiento con anticuerpos monoclonales.


Abstract Optic neuromyelitis or Devic's disease is a rare inflammatory disease of the central nervous system (CNS) that predominantly affects the optic nerve and spinal cord. The mechanism of the disease is given by the production of IgG antibodies whose main target is the acuaporine channel 4 (AQP4) that trigger an inflammatory and demyelinating process in the aforementioned structures. We present the case of a patient who developed chronic and fluctuating sensitive episodes with visual impairment, without improvement after conventional treatment. During the diagnostic approach we found demyelinating lesions and positive AQP4-antibodies, this lead to a diagnosis of optic neuromyelitis. A positive response was obtained to the therapy with monoclonal antibodies.

ABSTRACT

Resumen Las enfermedades desmielinizantes inflamatorias comprenden una serie de desórdenes de origen autoinmune que afectan la mielina a nivel del sistema nervioso central (SNC) y periférico. Pueden ser monofásicas, multifásicas, progresivas, monofocales o multifocales, y su diagnóstico suele ser de exclusión. Se presenta el caso de una paciente de 15 años que debuta con cefalea, ataxia, hemiparesia, oftalmoparesia y alteración de la conciencia. En la resonancia magnética nuclear se observaron lesiones compatibles con enfermedad desmielinizante. Se realizó diagnóstico de encefalomielitis diseminada aguda. La paciente respondió favorablemente al tratamiento con corticoides.


Abstract Inflammatory demyelinating diseases comprise a series of autoimmune disorders affecting myelin at the level of the central nervous system (CNS) and peripheral nervous system. They can be monophasic, multiphasic, progressive, monofocal or multifocal, and their diagnosis is usually of exclusion. We report the case of a 15-year-old female patient with headache, ataxia, hemiparesis, ophthalmoplegia and altered consciousness. Magnetic resonance imaging showed lesions compatible with demyelinating disease. Acute disseminated encephalomyelitis was diagnosed. The patient responded to treatment with corticosteroids.

ABSTRACT

Desde o primeiro relato de doença desmielinizante associada a tumores cerebrais por Scherer em 1938, inúmeros outros relatos de casos foram publicados fazendo associação desta doença com diferentes tumores primários do sistema nervoso central. Nosso trabalho descreve o caso de uma paciente de 23 anos com duas lesões encefálicas biopsiadas, mostrando inicialmente processo inflamatório desmielinizante que no seguimento desenvolve um oligodendroglioma anaplásico. A partir deste caso, realizamos uma revisão da literatura dessa associação específica, primeiramente publicada por Barnard e Jellinek em 1967, e ressaltamos a importância da diferenciação entre a forma desmielinizante tumefativa de uma neoplasia cerebral verdadeira. (AU)


Since the first report of demyelinating disease associated with brain tumors by Scherer in 1938, several other case reports have been published making association of this disease with different primary tumors of the central nervous system. Our paper describes the case of a 23 year old patient with two brain lesions, biopsied, initially showing a demyelinating inflammatory process that in the follow up develops an anaplastic oligodendroglioma. From this case, we conducted a literature review of this specific association, first published by Barnard and Jellinek in 1967, and emphasize the importance of difference in a tumefactive demyelinating lesions between of true brain neoplasm.
