Encefalitis aguda con síndrome cerebeloso secundario a neuroborreliosis / Cerebellar syndrome associated to Lyme neuroborreliosis: case report

La enfermedad de Lyme es la infección transmitida por garrapatas más común en Norteamérica y Europa. Sin embargo, en América Latina se han reportado pocos datos. Borrelia burgdorferi es capaz de invadir el sistema nervioso central causando la neuroborreliosis de Lyme. Se comunica el caso de una mujer joven con encefalitis y síndrome cerebeloso, una presentación poco frecuente, que se manifestó con cefalea, marcha atáxica, nistagmo y ptosis palpebral. Se realizó el diagnóstico con serología positiva por Western blot para Borrelia burgdorferi en suero. Recibió tratamiento con mejoría clínica. El diagnóstico de neuroborreliosis es difícil, ya que no existen hallazgos neurológicos o de imagen específicos. Se recomienda tener un mayor nivel de vigilancia epidemiológica en Latinoamérica, así como los antecedentes recreativos o viajes, que deben incluirse en la historia clínica para mejorar la aproximación diagnóstica.

Lyme disease is the most common tick-borne disease in North America and Europe. However, in Latin America, few data have been reported. Borrelia burgdorferi is capable of invading the central nervous system causing Lyme neuroborreliosis. This is a case report of a female with encephalitis and cerebellar syndrome, a rare manifestation, presented with generalized headache ataxic gait, nystagmus and palpebral ptosis. Serologic diagnosis was made for Borrelia burgdorferi and treatment was initiated with clinical improvement. Neuroborreliosis is a very difficult diagnosis, since there are no neurologic or imaging findings specific. It is recommended to physicians to have an enhanced level of surveillance in Latin America, as well as recreational/travel history of the patient, which should be included in the clinical record to improve the diagnostic approach.

Bilateral diaphragmatic paralysis and Lyme neuroborreliosis. Ten-years of follow-up / Parálisis diafragmática bilateral y neuroborreliosis de Lyme. Diez años de seguimiento

Abstract Borrelia burgdorferi infection (Lyme disease) is one of the few identifiable causes of neuralgic amyotrophy (AN). Bilateral diaphragmatic paralysis is considered rare in borreliosis, and the pattern of long-term recovery of diaphragm function is also uncertain. Transdiaphragmatic pressure is the gold standard for diagnosing bilateral diaphragmatic paralysis, a study that has been reported on a few occasions. We pres ent a case of AN associated with borrelia infection and bilateral diaphragmatic paralysis that provides a detailed follow-up of the spirometric evolution, the maximum static pressures in the mouth, and the transdiaphragmatic pressure from the onset of symptoms and in the long term. This case allows us to know one of the possible evolutionary profiles of diaphragmatic dysfunction in AN due to borreliosis.

Resumen La infección por Borrelia burgdorferi (enfermedad de Lyme) es una de las pocas causas identificables de amiotrofia neurálgica. La parálisis diafragmática bilateral es considerada rara en la borreliosis y el patrón de recuperación a largo plazo de la función del diafragma también es incierto. La presión transdiafragmática es el patrón de oro para el diagnóstico de parálisis diafragmática bilateral, un estudio que ha sido informado en pocas ocasiones. Se presenta un caso de amiotrofia neurálgica asociado a infección por Borrelia y parálisis diafrag mática bilateral, que aporta un seguimiento detallado de la evolución espirométrica, de las presiones estáticas máximas en la boca y de la presión transdiafragmática desde el inicio de los síntomas y a largo plazo. Este caso permite conocer uno de los posibles perfiles evolutivos de la disfunción diafragmática en la amiotrofia neurálgica por borreliosis.

Manifestações neuroftalmológicas associadas a doença de Lyme / Neuro-ophthalmological manifestations associated with Lyme disease

Resumo A doença de Lyme é uma infecção sistêmica causada pela espiroqueta Borrelia burgdorferi e transmitida pelo carrapato do gênero Ixodes sp. e espécie Amblyomma cajennense. A doença costuma se manifestar em três estágios clínicos distintos, que podem variar de acordo com as características de cada hospedeiro. O objetivo deste trabalho é relatar o caso de uma paciente de 33 anos com doença de Lyme que apresentou como manifestações neuroftalmológicas diplopia, lagoftalmo paralítico e ceratite punctata, com exames laboratoriais negativos. Embora a espiroqueta Borrelia burgdorferi tenha maior tropismo pelos tecidos da pele, sistema nervoso e articulações, o acometimento ocular não deve ter sua importância diminuída, sendo descrito neste relato de caso, que abordou os aspectos mais pertinentes à doença para auxiliar seu diagnóstico e tratamento.

Abstract Lyme disease is a systemic infection caused by the spirochete Borrelia burgdorferi and transmitted by the tick of the genus Ixodes sp. and species Amblyomma cajennense. The disease usually manifests itself in three distinct clinical stages, which may vary according to the characteristics of each host. The objective of this paper is to report the case of a 33-year-old patient with Lyme disease who presented as neuro-ophthalmological manifestations diplopia, paralytic lagophthalmos and punctate keratitis, with negative laboratory tests. Although the spirochete Borrelia burgdorferi has a greater tropism in the tissues of the skin, nervous system and joints, the ocular involvement should not be diminished, being described in this case report, which approached the most pertinent aspects to the disease to aid its diagnosis and treatment.

Mielitis transversa aguda en un viajero / Acute transverse myelitis in a traveler

La mielitis transversa aguda se define como un trastorno neuroinmune adquirido de la medula espinal, que ocurre como consecuencia de un evento primario o relacionado a enfermedades inflamatorias autoinmunes, infecciosas o post infecciosas. Entre los agentes etiológicos infecciosos se destaca Borrelia spp., antropozoonosis transmitida por garrapatas de la familia ixodidae. Los pacientes con enfermedad de Lyme desarrollan, entre un 10 a un 15%, manifestaciones neurológicas. El espectro clínico suele ser variado e incierto. Entre las manifestaciones clínicas de la neuroborreliosis de Lyme, la mielitis transversa aguda ha sido reportada entre el 4 al 5%. Se describe el caso de un viajero proveniente de zona endémica de enfermedad de Lyme con encefalomielitis secundaria a infección aguda por Borrelia burgdorferi que presentó resolución completa de los síntomas luego de finalizar el tratamiento antibiótico.

Acute transverse myelitis is defined as an acquired neuroimmune disorder of the spinal cord, which occurs as a consequence of a primary event, or directly related to an autoimmune inflammatory disease, an infectious or post-infectious disease. Amongst infectious etiologies, Borrelia spp., a tick-bourne anthropozoonosis of the ixodidae family, prevails. Approximately 10 to 15% of patients with Lyme disease undergo neurologic manifestations, with an assorted and uncertain array of clinical syndromes. Transverse myelitis accounts for up to 5% of Lyme neuroborreliosis. We describe the case of a traveler from endemic zone for Lyme disease, with encephalomyelitis secondary to acute infection by Borrelia burgderfori, with complete resolution of symptoms after concluding adequate antibiotic treatment.
