RESUMO

Las manifestaciones neuropsiquiátricas en los pacientes con lupus eritematoso sistémico (LES) y síndrome antifosfolípido (SAF) secundario son muy frecuentes. En ambos casos, la fisiopatología se correlaciona con vasculopatía asociada a anticuerpos antifosfolípido y neurotoxicidad por anticuerpos y citocinas. La corea es el único trastorno del movimiento incluido en los 19 síndromes neuropsiquiátricos del LES según el American College of Rheumatology, con presentación inusual (prevalencia del 2%), y puede ocurrir como primera manifestación de la enfermedad. Se describe el caso de una paciente de 17 años con corea desencadenada durante el embarazo como manifestación inicial de LES y SAF.Neuropsychiatric symptoms of systemic lupus erythematosus (SLE) and secondary antiphospholipid syndrome (APS) are very common. In both cases, pathophysiology is correlated to vasculopathy associated to antiphospholipid antibodies as well as neurotoxicity mediated by antibodies and cytokines. Chorea, instead, is the only movement disorder included in the 19 SLE's neuropsychiatric syndromes described by the American College of Rheumatology. Nevertheless, its presence is unusual with a prevalence of about 2%, and could appear as an early manifestation of the disease. The case of a 17-year-old pregnant woman in whom chorea was an early manifestation of SLE and APS.

RESUMO

OBJECTIVE: To present a case of chorea gravidarum and conduct a review of the published literature on the treatment for this condition, and on maternal and fetal prognosis. METHODS: Case presentation of a 16-year-old primiparous patient admitted to a Level III public hospital at 8 weeks of gestation complaining of involuntary head and limb movements and right lower limb hyperreflexia lasting three days. The patient had a history of Sydenham chorea. Treatment with antipsychotics and benzodiazepines was given to manage symptoms, and with benzathine penicillin to address the etiology, achieving control at 14 weeks. Treatment was discontinued at 35 weeks and the patient went on to have normal delivery at 39 weeks. A search was conducted in the Medline via PubMed, UptoDate, Medscape and Google Scholar databases using the terms "Pregnancy and Chorea Gravidarum". The search was limited to case reports and case series or review articles published between 2000 al 2019. RESULTS: Seven case reports and one review of the topic were found. In 4 of the 7 cases, treatment was based on haloperidol, benzodiazepines and chlorpromazine. Penicillin was used in one of two cases with a history of Sydenham chorea. Maternal and fetal prognosis was good in 6 of 7 cases, there was 1 case of intrauterine growth restriction. CONCLUSIONS: Treatment of gestation chorea is primarily expectant and the goal is to reduce symptoms. Maternal and fetal prognosis is good.

TITULO: COREA GRAVÍDICA: REPORTE DE CASO Y REVISIÓN DE LA LITERATURA. OBJETIVO: presentar un caso de corea gravídica y hacer una revisión sistemática de la literatura publicada sobre el tratamiento y pronóstico materno-fetal de la entidad. METODOS: se presenta el caso de una paciente de 16 años, primigesta, que ingresa a un hospital público de tercer nivel de complejidad, con 8 semanas de gestación, con clínica de 3 días de evolución caracterizada por movimientos involuntarios de la cabeza y las extremidades, con hiperreflexia en miembro inferior derecho. Antecedente de Corea de Sydenham. Se da tratamiento con antisicóticos y benzodiacepinas para la sintomatología y etiológico con penicilina benzatínica y control del cuadro a las 14 semanas. Suspendió el tratamiento a las 35 semanas. Parto normal a las 39 semanas. Se realizó una búsqueda en la base de datos de Medline vía PubMed, UptoDate, Medscape y Google Académico empleando los términos: "Pregnancy" and "Chorea Gravidarum". La búsqueda se limitó a reportes y series de casos o artículos de revisión, desde el año 2000 al 2019. RESULTADOS: se encontraron siete reportes de casos y una revisión de tema. El tratamiento se realizó con haloperidol benzodiacepinas y clorpromacina en cuatro de los siete casos. En uno de los dos casos con antecedentes de corea de Sydenham se utilizó penicilina. El pronóstico materno-fetal fue bueno en seis de siete casos, en un caso hubo restricción de crecimiento intrauterino. CONCLUSIONES: el tratamiento de la corea gestacional principalmente es expectante y su finalidad es disminuir la sintomatología, el pronóstico materno-fetal es bueno.

RESUMO

Los movimientos anormales corresponden a una de las patologías neurológicas que con menor frecuencia se presentan durante el embarazo. A excepción del temblor esencial y el síndrome de piernas inquietas, los demás son raros. Los estudios en este grupo de pacientes son escasos y antiguos dada la baja prevalencia. Se busca con este artículo dar a conocer al personal médico en general las características clínicas de patologías como la corea gravidarum, la distonía y la enfermedad de Huntington entre otros, y su relación con el embrazo, la frecuencia y las opciones adecuadas de tratamiento, dada la susceptibilidad de las pacientes y el alto riesgo de efectos adversos en el feto con sus respectivas complicaciones a corto y largo plazo. Para la revisión de la literatura se estructuró una estrategia de búsqueda utilizando los términos movimientos anormales, embarazo, corea gravidarum, síndrome de piernas inquietas, distonía, enfermedad de Parkison (MeSH y no Mesh), los cuales se articularon con operadores booleanos en las siguientes bases de datos: pubmed, ebscohost y embase, filtrando los resultados por artículos de revisión.

Abnormal movements are one of the rare neurological conditions that present during pregnancy. With the exception of essential tremor and restless legs syndrome, the rest are rare. Studies on this patient group are limited and old, given the low prevalence. With this article, it is sought to provide information to general medical professionals on the clinical characteristics of diseases including, among others, chorea gravidarum, dystonia, and Huntington's disease, as well as their relationship with pregnancy, their frequency, and appropriate treatment options, given the susceptibility of the patients and the high risk of adverse effects in the foetus with their respective short and long-term complications. A structured strategy was employed for the review of the literature, using the terms, abnormal movements, pregnancy, chorea gravidarum, restless legs syndrome, dystonia, Parkinson's disease (MeSH and non-MeSH), which were formulated with Boolean operators in the following data bases: PubMed, EBSCOhost and Embase, filtering the results for review articles.

RESUMO

BACKGROUND: Sydenham's Chorea is a frequent cause of chorea during pregnancy, chorea gravidarum. The aim of this article is to describe the effect of pregnancy in a consecutive series of patients with diagnosis of Sydenham's Chorea. METHODS: A chart review was performed of all patients with the diagnosis of Sydenham's Chorea followed up at our institution from 07/1993 through 08/2010 and who became pregnant. RESULTS: From 66 patients, 20 became pregnant. Of these 20 patients, 15 (75%) developed chorea gravidarum. Generalized chorea was found in 67% of these 15 patients, focal or multifocal chorea was identified in 20% and 13.4% developed hemichorea. In 80% of cases chorea began in the first 6 months of gestation. Three women with previous persistent chorea experienced worsening of the movement disorder during pregnancy. Remission occurred after delivery in 11 patients whereas the other four remained with non-disabling chorea during the first 12 months after delivery. Abortion occurred in two patients (13%). All patients with chorea gravidarum subsequently treated with oral contraceptives developed recurrence of chorea. CONCLUSIONS: Chorea gravidarum is a frequent complication of pregnancy in patients with previous history of Sydenham's Chorea and an increased risk of miscarriage should be considered. Our findings confirm the notion that chorea gravidarum results from hormonal changes acting on previously dysfunctional basal ganglia.

RESUMO

Chorea gravidarum is an uncommon condition characterized by involuntary movements, speaking alterations and in the affective status during first trimester pregnancy, the incidence is 1 by each 2275 pregnancies, it is self limiting and resolves when the pregnancy ends, most of the cases are idiopathic and the rest is associated to the antiphospholipid syndrome, rheumatic fever, thyrotoxicosis, systemic lupus erythematosus, syphilis, Huntington disease or induced by drugs. The recurrences can occur in the subsequent pregnancies. The dopamine antagonists as the haloperidol and the chlorpromazine are useful to control the symptoms and are safe at lower doses. A 22 years-old patient, second pregnancy, without prenatal care, who was admitted to the labor at 36.1 weeks of gestation and psychosis of pregnancy presenting involuntary movements, dysnea and behavior disorder of three days evolution. The initial treatment was with diazepam, two days after the patient presented amniotic rupture without uterine activity, the pregnancy was interrupted by C- section and a male newborn was obtained. She had a favorable evolution during puerperium. She was discharged of the hospital four days later, having only abnormal movement in the right hand. Antistreptolysins antibodies of 333, PCR 1:80 and negative rheumatoid factor. She had four normal pregnancies more after, being the last the 10th of February of 2007.
