RESUMO

La parálisis facial plantea un diagnóstico diferencial amplio en Pediatría, sobre todo cuando se acompaña de sintomatología que orienta en contra de una parálisis de Bell, por lo que resulta imprescindible realizar una correcta anamnesis. La enfermedad de Lyme es una de las posibles causas de parálisis facial, habiendo sido poco descrita en niños en España. Presentamos el caso de un varón de 11 años con diagnóstico de parálisis facial asociada a infección por B. burgdorferi con evolución favorable tras tratamiento con doxiciclina. (AU)


Facial palsy poses a wide differential diagnosis in pediatrics, especially when it is accompanied by symptoms that make it doubtful whether Bell's palsy is present. It is essential to perform a correct anamnesis to rule out diagnoses that require early detection and treatment to improve the prognosis. Lyme disease (EL) is one of the possible causes of facial palsy, having been seldom described in children in Spain. We present the case of an 11-years-old male with diagnosis of facial palsy associated with B. burgdorferi infection with favorable evolution after treatment with doxycycline. (AU)

RESUMO

INTRODUCTION: Lyme borreliosis (LB) in the paediatric population is an understudied entity with certain peculiarities. The objective of this study is to describe the characteristics of paediatric patients with LB, and their diagnostic and therapeutic processes. METHODS: Descriptive and retrospective study in patients up to 14 years old with suspected or confirmed LB between 2015 and 2021. RESULTS: A total of 21 patients were studied: 18 with confirmed LB (50% women; median age 6.4 years old) and 3 false positive of the serology. Clinical features in the 18 patients with LB were: neurological (3, neck stiffness; 6, facial nerve palsy), dermatological (6, erythema migratory), articular (1), and non-specific manifestations (5). Serological diagnosis was confirmatory in 83.3% of cases. A total of 94.4% patients received antimicrobial treatment (median duration, 21 days). All recovered with resolution of symptoms. CONCLUSIONS: LB diagnosis is difficult in the paediatric population and presents clinical and therapeutic peculiarities, with favourable prognosis.

RESUMO

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.

RESUMO

Introducción: La borreliosis de Lyme (BL) es una entidad poco estudiada en pediatría, pero con ciertas peculiaridades. El objetivo de este estudio es conocer las características de los pacientes pediátricos con sospecha y/o confirmación de BL. Métodos: Estudio descriptivo y retrospectivo en menores de 14 años con diagnóstico clínico y/o serológico, sospechoso o confirmado, de BL entre 2015 y 2021. Resultados: Se estudiaron 21 pacientes: 18 con diagnóstico final de BL (50% mujeres; mediana de edad 6,4 años) y 3 falsos positivos. En los casos de BL, las manifestaciones clínicas presentadas fueron: neurológicas (3, meningitis; 6, parálisis facial), dermatológicas (6, eritema migratorio), articulares (uno) e inespecíficas (2). El diagnóstico serológico fue confirmatorio en el 83,3% de los casos. El 94,4% recibió antibioterapia (mediana de duración 21 días) y la evolución fue satisfactoria en todos los casos. Conclusiones: El diagnóstico de la BL es difícil en la población pediátrica y presenta peculiaridades clínicas y terapéuticas, pero el pronóstico es favorable.(AU)

RESUMO

Borrelia burgdorferi, is the spirochete responsible for causing Lyme disease in man and different animals. Objective. Detect specific IgG type antibodies against Borrelia burgdorferi, in canines using the immunofluorescence technique and its correlation with other factors associated with Lyme disease. Methods. Blood was taken for IgG detection against Borrelia burgdorferi sl; Peripheral blood smear of the canines and hemolymph of the ticks to search for spirochetes with Wright staining and finally classification of the ticks using morphometric keys. Results. In the serological test, on average 69.0% of the canines sampled gave positive results in the different titrations. Bacterial structures were spirally visualized both in the peripheral blood of the canines and in the hemolymph of the ticks. The vector found was classified as Rhipicephalus sanguineus, until now not reported in the scientific literature as a carrier of Borrelia, nor associated with the disease.

RESUMO

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.

RESUMO

INTRODUCTION: To correctly interpret the serological markers of Lyme disease, it is very important to determine the region's infection rate. The aim of this study was to ascertain the prevalence of specific antibodies against Borrelia burgdorferi in a rural district in northern Spain. METHODS: The presence of IgG antibodies against B. burgdorferi was determined by qualitative enzyme immunoassay in the serum of 1,432 people divided into 3groups: 316 blood donors, 432 individuals who attended the hospital without infection and 684 for whom Lyme serology testing was specifically requested as part of a differential diagnosis. In the latter group, the presence or absence of an occupational risk factor was recorded. RESULTS: Antibodies against B. burgdorferi were detected in 189 individuals (13.2%): 16 (5.1%) in the blood donors group, 62 (14.4%) in subjects who attended hospital without infection and 111 (16.2%) in subjects in whom a differential diagnosis of Lyme disease was requested (p < 0.0001). In subjects with an occupational risk factor, the prevalence was 23.5%, peaking at 45.8% in men over 65 years. CONCLUSION: Our study showed a high prevalence of antibodies against B. burgdorferi and higher than that seen in other areas with similar characteristics in Spain. However, our results are similar to those published from other European regions. The prevalence in the blood donors group was lower than that observed in the other groups. Older age, the male gender and occupational risks were associated with a higher prevalence of Lyme disease.

RESUMO

RESUMEN La enfermedad de Lyme es una zoonosis transmitida por la picadura de garrapatas del género Ixodes sp. Ha sido descrita con más frecuencia en zonas endémicas de países meridionales. Sus manifestaciones clínicas son muy variables y se presentan de acuerdo con el estadio clínico de la enfermedad, teniendo así el compromiso ocular un espectro clínico muy variado que incluye manifestaciones desde la superficie ocular hasta la inflamación del segmento posterior. Se presenta el caso de un paciente de 72 años con un viaje reciente a los Estados Unidos (EE. UU.), atendido en la consulta particular por un oftalmólogo supraespecialista en uveítis de la ciudad de Medellín. El paciente hacía un mes refería una disminución de la agudeza visual (AV) en su ojo izquierdo y al examen oftalmológico presentó signos clínicos de panuveítis no granulomatosa asociada a un edema macular y vasculitis retinal. Se confirmó la enfermedad de Lyme en fase tardía por la presencia de anticuerpos en sangre por Western blot. Se realizó tratamiento exitoso con antibióticos (doxiciclina), con recuperación de la AV y la mejoría completa de los signos inflamatorios intraoculares.


SUMMARY Lyme Disease is a zoonosis transmitted by arthropods that has been described with more frequency in endemic zones of meridional countries. Its clinical manifestations vary according to the clinical stage of the disease. The eye can be affected in many forms including the involvement of the ocular surface and the posterior segment, with more severe inflammation of the retina and the choroid. We present a case of a 72-year male with a recent trip to EEUU who complained of decreasing vision in his left eye had clinical signs of non-granulomatous panuveitis with macular edema and retinal vasculitis. Lyme disease was confirmed with positive antibodies in blood and Western blot test, and the patient was successfully treated using oral Doxycycline. His visual acuity improved and had a resolution of the intraocular inflammation after the specific treatment.

RESUMO

Resumen: Se comunica el caso de una paciente de 29 años de edad, originaria y residente de la Ciudad de México, que inició su padecimiento con dolor en el segundo dedo de la mano izquierda posterior a una visita al bosque de Aragón, que progresó con náusea y diarrea, así como artralgias incapacitantes con predominio en las manos y los pies sin eritema multiforme en la mano. A su ingreso al hospital tuvo marcadores de inflamación de 19 x 103/μL leucocitos y proteína C reactiva de 28 mg/dL, que se elevaron durante su estancia hospitalaria; ante la falta de respuesta al tratamiento médico y múltiples pruebas negativas se decidió realizar Western Blot para ricketsias con lo que se obtuvo resultado positivo para Borrelia burgdorferi, con lo que se estableció el diagnóstico definitivo de borreliosis de Lyme; la paciente recibió tratamiento adecuado y tuvo mejoría clara. La enfermedad de Lyme es una zoonosis transmitida por las garrapatas del género Ixodes causadas por la espiroqueta Borrelia burgdorferi. La Ciudad de México no se ha reportado como zona endémica por lo que comunicamos este caso.


Abstract: This paper reports the case of a 29-year-old female patient, who was originally from Mexico City and began her condition with pain in the second finger of left hand after a visit to the Aragon forest in Mexico City, progressing with nausea and diarrhea, as well as incapacitating arthralgias with predominance in hands and feet without erythema multiforme in hand. Upon admission, she had inflammation markers of 19 x 103/μL leukocytes and C-reactive protein of 28 mg/dL, which were elevated during her hospital stay; due to the lack of response to medical treatment and multiple negative tests, a Western Blot test for ricketsias was done obtaining a positive result for Borrelia burgdorferi, establishing the definitive diagnosis of Lyme borreliosis, receiving adequate treatment and presenting clear improvement. Lyme disease is a zoonosis transmitted by the ticks of the genus Ixodes caused by the spirochete Borrelia burgdorferi. Mexico City has not been reported as an endemic area, which is why we report this case.

RESUMO

INTRODUCCIÓN Las enfermedades zoonóticas transmitidas por garrapatas (tales como rickettsiosis y borreliosis) son consideradas enfermedades emergentes y reemergentes en numerosos lugares del mundo, incluso en Argentina. La Reserva Ecológica Costanera Sur es un área urbana protegida ubicada en la Ciudad Autónoma de Buenos Aires que se caracteriza por una gran cantidad de ambientes de origen artificial, como bañados, lagunas, pastizales, matorrales y bosques, además de las playas del Río de la Plata. OBJETIVOS Estudiar los aspectos eco-epidemiológicos de las garrapatas y de los microorganismos patógenos transmitidos por garrapatas en la Reserva Ecológica Costanera Sur de la Ciudad Autónoma de Buenos Aires en el período 2011-2015. MÉTODOS Se realizaron muestreos para recolectar garrapatas de vegetación y de hospedadores como perros y distintas especies de roedores. Mediante técnicas moleculares se buscó la presencia de microorganismos de los géneros Rickettsia (fragmento del ARNr 23S-5S) y Borrelia (fragmento del ARNr 16S). RESULTADOS En total se recolectaron 1090 garrapatas de la vegetación (454 de la especie Amblyomma aureolatum, 653 Ixodes auritulus y 1 Amblyomma triste) y 67 de los perros (64 A. aureolatum, 2 Rhipicephalus sanguineus sensu lato y 1 A. triste). No se detectaron garrapatas en los 201 roedores revisados. Mediante PCR se estudiaron 899 garrapatas (375 A. aureolatum, 523 I. auritulus y 1 A. triste), y se detectó un 8,3% de I. auritulus positivos al género Borrelia. Todas las garrapatas resultaron negativas al género Rickettsia. El producto amplificado positivo a Borrelia pudo ser secuenciado, con un 97,9% de identidad respecto a distintas secuencias del complejo Borrelia burgdorferi sensu lato halladas en garrapatas del género Ixodes en el hemisferio norte. DISCUSIÓN La presencia abundante de las garrapatas A. aureolatum e I. auritulus, así como la detección del complejo B. burgdorferi s. l. en la región resultan de suma importancia para la salud pública.

RESUMO

RESUMEN Esta es una revisión crítica y organizada de la información disponible y actualizada acerca de la enfermedad de Lyme y la infección por Borrelia en el Perú. Varios estudios de serología contra Borrelia burgdorferi, y de casos de enfermedad de Lyme han sido reportados en el Perú en las pasadas dos décadas. Nueva información sugiere la existencia de nuevas especies de Borrelia burgdorferi sensu lato en Sudamérica, y posiblemente en el Perú. Futuros estudios genéticos y microbiológicos en esta parte del continente, no sólo en casos con Western blot indeterminado, sino también en vectores y posibles reservorios, son necesarios para medir la extensión de estas nuevas especies de Borrelia y su implicancia clínica.


ABSTRACT This is a critical and organized review of all the available and updated information on Lyme disease and Borrelia infection in Peru. Several studies of positive serology to Borrelia burgdorferi and several cases of Lyme disease have been reported in Peru in the last two decades. New information suggests that new species of Borrelia burgdorferi sensu lato do exist in South America, and possibly in Peru. Future genetic and microbiology studies in this part of the continent, not only in cases with an indeterminate Western blot but in vectors and possible reservoirs as well, are necessary to measure the extent and clinical implications of these new Borrelia species

RESUMO

Resumen Se comunica el caso de un paciente que refirió mordeduras por garrapatas 18 meses previos en las piernas y el cuello durante su estancia en Tequesquitengo, en el estado de Morelos, los siguientes meses continuó con cansancio, mareo, dolores musculares, artritis, pérdida de peso y alteraciones en la memoria reciente. Se establecieron diagnósticos diferenciales y se realizó estudio de Western Blot para B. burgdorferi, con lo que se estableció el diagnóstico de manifestaciones tardías de la enfermedad de Lyme. Esta enfermedad es una zoonosis trasmitida por las garrapatas Ixodes; cerca de 300,000 casos ocurren cada año en Estados Unidos. La manifestación clínica más común en la forma temprana lo constituye el eritema migratorio, puede haber manifestaciones neurológicas y cardiacas. Es posible que fenómenos multifactoriales, como los cambios climáticos, favorezcan la extensión de esta zoonosis fuera del tradicional territorio estadounidense. Debemos tener presente en nuestra práctica clínica las manifestaciones de la enfermedad de Lyme para su diagnóstico y tratamiento oportunos, cualquiera que siga siendo su incidencia geográfica.


Abstract We present the case of a patient who referred tick bite 18 months previous in legs and neck during the stay in Tequesquitengo, Morelos state, continuing the following months with fatigue, dizziness, muscle aches, arthritis, weight loss and alterations in recent memory. Differential diagnoses and Western blotting were performed for B. burgdorferi, which established the diagnosis of late manifestations of Lyme disease. Lyme disease is a zoonosis transmitted by Ixodes ticks and occurs in approximately 300,000 cases annually in the United States. The most frequent clinical manifestation in the early form is the erythema migrans, being able to present neurological and cardiac manifestations. It is possible that multifactorial phenomena, such as climate changes, favor the extension of this zoonosis outside the traditional territory of North America. We must take into account in our clinical practice the manifestations of Lyme disease for its timely diagnosis and treatment, regardless of its geographical incidence.

RESUMO

Resumen Actualmente, el estudio de la borreliosis canina adquiere mayor relevancia, ya que el perro es considerado como un importante centinela del complejo Borrelia burgdorferi sensu lato, el cual podría desempeñar un papel clave en la dispersión de garrapatas de las áreas selváticas al ambiente doméstico. En México, la distribución y presencia de genoespecies patógenas de B. burgdorferi en perros y sus garrapatas aún no ha sido investigada. Por tal motivo, la presente investigación tiene como objetivo detectar y estimar la prevalencia de B burgdorferi s.l. en perros y sus garrapatas en dos comunidades rurales de Yucatán, México. En cada comunidad se visitaron 50 viviendas donde se estudiaron 144 muestras de sangre de perros por punción de la vena safena, así como la colecta de sus garrapatas. Se colectaron un total de 846 garrapatas de las especies Ixodes affinis (33 / 846), Rhipicephalus sanguineus sensu lato (786 / 846) y Amblyomma mixtum (27 / 846). Para detectar la presencia de B. burgdorferi s.l. en dichas muestras, se amplificó el gen conservado flaB y las lipoproteínas de membrana externa, ospC y p66, mediante el uso de la reacción en cadena de la polimerasa. La prevalencia obtenida en sangre de perros fue de 17.3 % (25 / 144) para flaB, 12.50 % (18 / 144) para el gen p66 y 1.38 % (2 / 144) para el gen ospC. De las garrapatas analizadas, R. sanguineus s.l. tuvo una prevalencia de infección de 0.89 %, A. mixtum de 5.88 % e I. affinis de 15.15 %, siendo esta última especie la que presentó mayor prevalencia. Dos perros y sus garrapatas I. affinis fueron positivos al gen flaB. Solamente una garrapata R. sanguineus s.l. fue positiva al gen p66 y ninguna especie de garrapata fue positiva al gen ospC. Este estudio confirma la existencia de B. burgdorferi s.l. en perros y sus garrapatas en comunidades rurales de Yucatán, México. La detección de Borrelia en perros podría ser un criterio importante para la evaluación del riesgo de borreliosis en humanos, ya que el perro puede emplearse como indicador epidemiológico para la identificación de nuevos focos de esta enfermedad.


Abstract In Mexico, the distribution and the presence of pathogenic genospecies of B. burgdorferi in dogs and their ticks has not been extensively investigated. The study of canine borreliosis is acquiring greater relevance, since the dog is considered to be an important sentinel for pathogens pertaining to the complex Borrelia burgdorferi sensu lato; in addition, dogs could be playing a key role in the spread of ticks from forested areas into the domestic environment. This study aimed to detect and estimate the prevalence of B. burgdorferi s.l. in dogs and their ticks in two rural communities of Yucatán, Mexico. In each community, 50 houses were visited, where 144 blood samples from dogs were studied by puncture of the saphenous vein, as well as the collection of their ticks. To detect the presence of B. burgdorferi s.l. in these samples, the conserved gene flaB, p66 and ospC were PCR amplified. A total of 144 dog blood samples, and 846 of ticks were obtained from the examined animals. Considering tick species, Rhipicephalus sanguineus sensu lato (786 / 846) was common, while Ixodes affinis (33 / 846), and Amblyomma mixtum (27 / 846) resulted less frequent. As per gene conservation, the prevalence of B. burgdorferi in canine blood was 17.3 % (25 / 144) to flaB, 12.50 % (18 / 144) for p66 and 1.38 % (2 / 144) for the ospC gene. Within the analyzed ticks, R. sanguineus s.l. had a prevalence of 0.89 %, A. mixtum 5.88 % and I. affinis 15.15 %, being this last species the one that presented higher prevalence. Two dogs and their ticks I. affinis were positive to the flaB gene. Only a tick R. sanguineus s.l. was positive to the gene p66 and no tick species was positive the ospC gene. This study confirmed the existence of B. burgdorferi s.l. in dogs and their ticks in rural communities of Yucatán, Mexico. The detection of Borrelia in dogs may be an important criterion for the evaluation of the risk of borreliosis in humans, since the dog can be used as an epidemiological indicator for the identification of new outbreaks of this disease.

RESUMO

INTRODUCTION: Borrelia miyamotoi is a tick-borne pathogen belonging to the relapsing fever group. It had not been reported from Spain, but its wide distribution and the presence of the tick-vector (Ixodes ricinus) made us suspect its circulation. The aim of this study was to investigate the presence of Borrelia spp. in I. ricinus in Spain. METHODS: A total of 652 I. ricinus nymphs collected in northern Spain were processed. The DNA was extracted using incubations with ammonium hydroxide. Borrelia spp. DNA was amplified using Borrelia-specific PCR assays (glpQ, 16S rRNA and flagellin genes). RESULTS: B. miyamotoi was amplified in 4 specimens, and Borrelia burgdorferi sensu lato in 27 (8 Borrelia afzelii, 7 Borrelia garinii, 8 Borrelia lusitaniae, 3 Borrelia valaisiana and 1 B. burgdorferi sensu stricto). CONCLUSION: B. miyamotoi should be considered in the differential diagnoses of patients with confirmed or suspected tick-bite in Spanish endemic areas for Lyme disease.

RESUMO

OBJECTIVE: The main aim of this study was to determine the usefulness of an early diagnosis of Lyme disease (LD) in Primary Health Care Centres (PHCC) using the ELISA test as serological screening technique. METHODS: A retrospective study (2006-2013) was performed in order to determine the anti-Borrelia seropositivity in 2,842 people at risk of having LD. The possible relationship between the environment and the area of residence with anti-Borrelia seropositivity was also studied according to the origin of the specimens (PHCC/Hospital). RESULTS: Overall, 15.2% of samples were positive to Borrelia spp. Seropositivity was significantly higher in samples sent by PHCC doctors than those sent by Hospital doctors. Seropositivity was significantly higher in rural than in urban populations and in those who live in mountainous or flat areas. The percentage of seropositivity has increased over the years. CONCLUSIONS: The role of the PHCC doctor is essential for achieving an early diagnosis of Lyme disease, as a higher percentage of seropositives was detected in samples submitted from PHCC. Furthermore, most early localised LD patients were diagnosed in PHCC, avoiding the appearance of sequelae. Therefore, detection of Borrelia specific antibodies using an ELISA assay is a useful screening test for patients at risk of LD.

RESUMO

RESUMEN El síndrome de Lyme crónico representa un término controversial que agrupa un conjunto de síntomas persistentes e inespecíficos, en su mayoría reumatológicos o neurológicos, dentro de los cuales se encuentra la enfermedad postLyme, cuya incidencia epidemiológica es baja, el conocimiento fisiopatológico es controversial y el abordaje diagnóstico se basa especialmente en la interpretación clínica, dirigiendo su enfoque terapéutico hacia la resolución sintomática. Se presenta un caso de una mujer de 17 años, con enfermedad de Lyme de reciente diagnóstico, de aparente evolución de 3 años, con diagnóstico previo de enfermedad desmielinizante, que consultó por deterioro neurológico. Se revisan consideraciones científicas sobre su aproximación clínica y principios terapéuticos, los cuales se contrastan con los aplicados.


SUMMARY Chronic Lyme syndrome represents a controversial term that groups together a set of persistent and nonspecific symptoms, mostly rheumatological and / or neurological, among which is the Post Lyme Disease, whose epidemiological incidence is low, pathophysiology is controversial and the diagnostic approach is based especially on clinical interpretation, directing its therapeutic approach towards symptomatic resolution. We present a case of a female patient of 17 years of age with Lyme disease of recent diagnosis of apparent evolution of 3 years, with previous diagnosis of demyelinating disease, who consulted for neurological deterioration. Scientific considerations on its clinical approach and therapeutic principles are reviewed, contrasting them with those applied.

RESUMO

Introducción: La borreliosis de Lyme no ha sido notificada oficialmente en Cuba pero existen sospechas clínico-epidemiológicas y evidencias serológicas sugestivas de la infección por Borrelia burgdorferi sensu lato, su agente causal. Objetivo: Describir aspectos clínicos y epidemiológicos de pacientes que padecieron la enfermedad y explorar el nivel de conocimientos en personal médico. Métodos: Se realizó revisión documental de los Registros de Diagnóstico de la infección por B. burgdorferi sensu lato, entre 2007-2016, conservados en el Laboratorio Nacional de Referencia del Instituto de Medicina Tropical Pedro Kourí y se combinó con un estudio exploratorio del nivel de conocimientos sobre la enfermedad en personal médico. Resultados: Hubo incremento discreto en el número de muestras recepcionadas. El suero y el líquido cefalorraquídeo, fueron las muestras de elección para el diagnóstico, realizado por ensayos inmunoenzimáticos. Se confirmó la infección en 10,9 por ciento de las muestras de sueros recibidas. Las lesiones en piel, adenopatías regionales, parálisis faciales, dificultad para la marcha y otras, motivaron la sospecha clínica de esta enfermedad. Predominó el antecedente de picaduras por insectos o garrapatas. El 70 por ciento de los médicos encuestados plantearon conocer sobre la enfermedad de Lyme, pero de ellos solo el 46 por ciento reconoció al menos una de sus manifestaciones clínicas. Conclusiones: Los aspectos clínicos y epidemiológicos descritos, deben ser tomados en cuenta en pacientes con sintomatologías compatibles con la infección por B. burgdorferi sensu lato. Se requieren intervenciones educativas en el personal médico para un mejor reconocimiento clínico de esta entidad infecciosa y propiciar un mejor diagnóstico(AU)


Introduction: Lyme borreliosis has not been officially reported in Cuba but there are clinical-epidemiological suspicions and serological evidence that are suggestive of its causal agent: the infection by Borrelia burgdorferi sensu lato. Objective: To describe clinical and epidemiological aspects of patients who suffered from the disease and to explore the level of knowledge about it in medical personnel. Methods: A documentary review of the Diagnostic Records of B. burgdorferi sensu lato infection that are preserved in the National Reference Laboratory of Pedro Kourí Institute of Tropical Medicine was carried out from 2007 to 2016, and it was combined with an exploratory study of the knowledge´s level about the disease in medical personnel. Results: There was a slight increase in the number of samples received. Serum and cerebrospinal fluid were the samples chosen for a diagnosis that was performed by enzyme immunoassay. Infection was confirmed in 10.9 percent of the serum samples received. Skin lesions, regional lymphadenopathy, facial paralysis, difficulty for walking and others led to the clinical suspicion of this disease. It was predominant the antecedent of insect or tick bites. Seventy percent of the doctors surveyed said they knew about Lyme disease, but only 46 percent of them acknowledged at least one of its clinical manifestations. Conclusions: B. burgdorferi sensu lato infection should be taken into account in patients with symptoms compatible with Lyme disease. Educational interventions are required in the medical personnel for a better clinical recognition of this infectious entity and to promote a better diagnosis(AU)

RESUMO

Resumen Presentamos el caso clínico de una mujer norteamericana que consultó en nuestro país por un eritema migrans múltiple, diagnosticándose una enfermedad de Lyme. Este cuadro infeccioso es causado por espiroquetas del complejo Borrelia burgdorferi sensu lato (Bbsl) y es transmitido por la mordedura de garrapatas. Tradicionalmente Bbsl había sido detectada en garrapatas sólo en el hemisferio norte. Sin embargo, desde el 2013 ha habido reportes en Sudamérica. En Chile, recientemente se describió Borrelia chilensis, la cual no tiene una enfermedad asociada en humanos. Se discuten aspectos del agente infeccioso, su epidemiología, sus vectores y nuevos hallazgos en Sudamérica. Además, se plantean los criterios diagnósticos clínicos, de laboratorio y tratamiento, de acuerdo a la etapa en su historia natural.


This is a case report of an american woman who consulted in our country for multiple erythema migrans, from which a Lyme disease was diagnosed. This infectious disease is caused by spirochetes from the Borrelia burgdorferi sensu lato complex (Bbsl) and is transmitted by the bite of ticks. Traditionally Bbsl had been detected in ticks only in the Northern Hemisphere. However, since 2013 there have been reports in South America. In Chile, Borrelia chilensis was recently described, which does not have an associated disease in humans. Aspects of the infectious agent, its epidemiology, its vectors and new findings in South America are discussed. Likewise, the clinical diagnostic criteria, laboratory and appropriate treatment are proposed, according to the stage in their natural history.

RESUMO

Introducción. La enfermedad de Lyme es una zoonosis multisistémica causada por Borrelia burgdorferi sensu lato. Esta espiroqueta circula en un ciclo enzoótico entre un reservorio vertebrado primario y las garrapatas. Se ha encontrado que varias especies de roedores son eficientes reservorios naturales de B. burgdorferi s.l. Objetivo. Estimar la prevalencia de B. burgdorferi s.l. en roedores sinantrópicos en dos comunidades rurales de Yucatán, México. Materiales y métodos. Se capturaron 123 roedores (94 Mus musculus y 29 Rattus rattus ) para obtener muestras de tejidos de oreja y vejiga. Para la detección de B. burgdorferi s.l. en las muestras, se amplificaron los genes de la flagelina B ( fla B ) y las lipoproteínas de membrana externa, ospC y p66 , mediante reacción en cadena de la polimerasa, y se secuenciaron los amplicones obtenidos. Resultados. La frecuencia de infección por B. burgdorferi s.l. en roedores fue de 36,5 % para flaB (45/123), de 10,5 % (13/123) para p66 y de 3,2 % (4/123) para ospC . En R. rattus la frecuencia de infección fue de 17,2 % y en M. musculus fue de 42,5 %. La frecuencia de infección de B. burgdorferi s.l. en los tejidos estudiados fue de 11,3 % (14/123) en muestras de tejido de vejiga y de 17,0 % (21/123) en las de oreja. No se encontraron diferencias estadísticas (p>0,05) en la frecuencia de infección entre los dos tipos de muestras de tejido utilizadas para el diagnóstico. El gen ospC presentó 98 % de homología con la especie Borrelia garinii , una de las especies heterogéneas del complejo B. burgdorferi s.l. Conclusiones. Los roedores presentaron una alta prevalencia de infección con B. burgdorferi s.l.; las especies M. musculus y R. rattus podrían jugar un papel importante en la continuidad de la presencia de esta bacteria en comunidades rurales de Yucatán, México.


Introduction: Lyme disease is a multisystemic zoonotic disease caused by Borrelia burgdorferi sensu lato. This spirochete circulates in an enzootic cycle between the primary vertebrate reservoir and its tick vectors. Different species of rodents are known to be efficient natural reservoirs for B. burgdorferi s.l. Objective: To estimate the prevalence of B. burgdorferi s.l. in synanthropic rodents from two rural communities of Yucatán, México. Materials and methods: A total of 123 rodents (94 Mus musculus and 29 Rattus rattus ) were trapped, and ear and bladder samples were collected. Flagelin B ( flaB ) genes and outer membrane lipoproteins ospC y p66 were amplified in order to detect B. burgdorferi s.l. presence in the samples. The obtained amplicons were sequenced. Results: The overall infection rates in rodents were 36.5% for flaB (45/123), 10.5% (13/123) for p66, and 3.2% (4/123) for ospC . Rattus rattus had 17.2% of infection and M. musculus , 42.5%. From all examined tissue, 11.3% (14/123) of bladders, and 17.0% (21/123) of ears were infected with the spirochete Borrelia burgdorferi s.l. No statistical differences (p>0.05) were found between the two tissue samples used for diagnosis. The ospC gen was 98% homologous to Borrelia garinii , one species of the B. burgdorferi s.l. complex. Conclusions: We concluded that rodents have a high prevalence of B. burgdorferi s.l. infection, and both species of rodents, M. musculus and R. rattus, might be playing an important role in the maintenance of this bacterium in rural communities of Yucatán, México.

RESUMO

OBJECTIVES: To determine the percentage of Lyme patients with articular manifestations in NW Spain and to know their evolution and response to treatment. PATIENTS: A retrospective study (2006-2013) was performed using medical histories of confirmed cases of Lyme disease showing articular manifestations. Clinical and laboratory characteristics, together with the treatment and evolution of the patients, were analysed. RESULTS: Seventeen out of 108 LD confirmed patients (15.7%) showed articular manifestations. Regarding those 17 patients, 64.7%, 29.4% and 5.9% presented arthritis, arthralgia and bursitis, respectively. The knee was the most affected joint. Articular manifestations were often associated to neurological, dermatological and cardiac pathologies. Otherwise, most patients were in Stage III. The 11.8% of the cases progressed to a recurrent chronic arthritis despite the administration of an appropriate treatment. CONCLUSIONS: Lyme disease patients showing articular manifestations should be included in the diagnosis of articular affections in areas of high risk of hard tick bite, in order to establish a suitable and early treatment and to avoid sequels.
