ABSTRACT

La infección por Bartonella henselae (BH) adopta diversas formas de presentación clínica en pediatría. Según la bibliografía la forma de presentación más frecuente en pacientes inmunocompetentes es la linfadenopatía única asociada a fiebre. En el 85 % de los casos se compromete un solo ganglio siendo los axilares y los epitrocleares los más frecuentemente involucrados. Existen otras formas de presentación menos frecuentes que debemos tener en consideración, para poder realizar un diagnóstico precoz e indicar un tratamiento adecuado si así lo requiere. El diagnóstico requiere de la sospecha clínica del equipo de salud tratante, junto al antecedente epidemiológico, los hallazgos clínicos del examen físico y la realización de serologías que incluyan el dosaje de inmunoglobulina M y G. Los objetivos del presente trabajo fueron reconocer las manifestaciones clínicas típicas y atípicas de la EAG por Bartonella henselae, describir la epidemiología, características clínicas y evolución de esta enfermedad que se presentaron en nuestro hospital. Se estudiaron un total de 187 pacientes. La media de edad fue de 7.6 años (rango 1-14); siendo 53.5% de género masculino. Las formas de presentación más frecuentes en nuestro trabajo fueron la adenitis y la fiebre. La mayoría recibió diversos esquemas de tratamiento antibiótico, secundario al retraso en el diagnóstico. La tasa de hospitalización fue muy baja, remitió con tratamiento ambulatorio con antibióticos o sin ellos (AU)


Bartonella henselae infection has different clinical presentations in pediatrics. According to the literature, the most common form of presentation in immunocompetent patients is single lymphadenopathy associated with fever. In 85 % of the cases a single lymph node is involved, with the axillary and epitrochlear nodes being the most commonly involved. There are other, less frequent, forms of presentation that should be taken into consideration in order to make an early diagnosis and indicate appropriate treatment if required. Diagnosis relies on clinical suspicion by the treating healthcare team, together with the epidemiological history, clinical findings on physical examination, and serology including immunoglobulin M and G dosage. The objectives of this study were to identify both the typical and atypical clinical manifestations of Bartonella henselae cat scratch disease, to describe the epidemiology, clinical characteristics, and outcomes of cases presenting at our hospital. A total of 187 patients were studied. The mean age was 7.6 years (range 1-14); 53.5% were male. The most frequent forms of presentation in our study were adenitis and fever. Most of them received different antibiotic treatment regimens due to delayed diagnosis. The hospitalization rate was very low and the disease typically resolved with outpatient treatment, with or without antibiotics (AU)

ABSTRACT

La miositis de origen vírico o bacteriano es frecuente en la edad pediátrica. Causa dolor muscular y debilidad, con fiebre y malestar general. Una causa es la infección por Bartonella henselae, bacteria implicada en la enfermedad por arañazo de gato que, a veces, causa afectación multisistémica. Se presenta el caso de una adolescente que acudió al servicio de urgencias por mialgia intensa, malestar, adelgazamiento y esplenomegalia. En el labortorio se observaron parámetros inflamatorios elevados. Refería contacto con un gato. Entre los estudios realizados, la resonancia magnética (RM) de miembros inferiores mostró una imagen compatible con miositis inflamatoria bilateral. En la RM abdominal, se observaron tres lesiones esplénicas no detectadas previamente y el fondo de ojo mostraba una lesión compatible con oclusión arterial retiniana o vasculitis. Se indicó tratamiento antibiótico por vía intravenosa durante 21 días con cefotaxima y cloxacilina, tras los cuales desaparecieron los signos y síntomas, aunque los reactantes inflamatorios persistieron elevados. Con base en el cuadro clínico (miositis + coriorretinitis + absceso esplénico) se pensó en una posible infección por B. henselae y se inició tratamiento oral con azitromicina y rifampicina durante 14 días. Luego del tratamiento, los valores de laboratorio fueron normales, así como la RM de control, y se constató una IgG positiva para la bacteria


Infectious myositis, whether viral or bacterial, is frequent in pediatric age. It causes muscle pain and weakness, associated with fever and general malaise. One cause is Bartonella henselae, responsible for cat scratch disease, which sometimes causes systemic symptoms. We report the case of an adolescent who came to the emergency room with intense myalgia, malaise, weight loss and splenomegaly. Blood tests showed high inflammatory markers. She had been in touch with a cat. Studies were carried out including: lower limbs MRI suggestive of bilateral inflammatory myositis, abdominal MRI with three previously undetected splenic lesions and dilated fundus examination that showed possible retinal arterial occlusion or vasculitis. After 21 days of intravenous antibiotic therapy (cefotaxime + cloxaciline), she became asymptomatic, but inflammatory markers remained high. Suspecting Bartonella henselaeinfection (myositis + chorioretinitis + splenic abscess), oral azithromycin and rifampicin were prescribed for 14 days. Blood tests and control MRI became normal, and IgG was positive.

ABSTRACT

O diagnóstico diferencial das linfadenomegalias supuradas deve se basear na historia clínica e em exames complementares, principalmente na análise histopatólogica. A Bartonella henselae, bastonete gram-negativo fastidioso que frequentemente causa bacteriemia em gatos, constitui agente que sempre deve ser associado a linfadenomegalia. Os gatos são reservatórios importantes desse microrganismo. A doença da arranhadura do gato normalmente cursa com poliadenopatias relacionadas ao local de inoculação (por arranhadura ou lambedura) e sintomatologia geral leve, sendo normalmente autolimitada. Raramente a doença complica com acometimento visceral, ocular e neurológico. Em alguns casos, há poliadenopatia persistente e supurada. Este relato apresenta as alterações descritas por mulher de 79 anos, com poliadenopatia cervical ulcerada, surgida após contato próximo com felino. As alterações clínicas e histopatológicas foram sugestivas de doença da arranhadura do gato, de evolução prolongada. Houve boa resposta a antimicrobianos. Este trabalho ilustra o amplo diagnóstico diferencial de linfadenomegalias persistentes, que deve incluir sempre a infecção pela Bartonella henselae entre as prováveis etiologias.


Differential diagnosis of suppurative lymphadenomegalies must be based on clinical history and laboratory tests, particularly in histhopatological analysis. The Bartonella henselae is a fastidious gram-negative rod-shaped bacterium that commonly causes bacteremia in cats, frequently associated with lymphadenopathy. Cats are important reservoirs of this organism. Cat scratch disease usually happens with polyadenopathies related to the inoculation local (by scratching or licking) and general light symptoms, besides being selflimiting. This disease is rarely complicated with visceral, ocular and neurological injuries. Some cases show persistent and festering polyadenopathy. This report shows changes described by a 79 old-year-woman, who presents ulcerated cervical polyadenopathy, acquired after close contact with cats. Clinical and histopathological changes were suggestive of cat scratch disease, of long time evolution. There was good response to antibiotics. This paper illustrates the wide differential diagnosis of persistent lymphadenomegalies, which should always include infection with Bartonella henselae among several etiologies.

ABSTRACT

La infección por Bartonella henselae se presenta característicamente con adenopatías regionales y fiebre de intensidad variable, entidad conocida como “enfermedad por arañazo de gato”. Alrededor de 5 a 10 por ciento de los casos desarrolla compromiso ocular, entre los que destacan el síndrome óculo-glandular de Parinaud, la neuro-retinitis y la retino-coroiditis focal. A continuación se presentan dos pacientes con infección aguda por B. henselae y compromiso ocular. Ambos recibieron tratamiento y evolucionaron con recuperación completa de la visión.


Cat scratch disease is the main clinical presentation of Bartonella henselae infection. However, ocular manifestations of bartonellosis occur in about 5 to 10 percent of the patients, mainly presenting as neuroretinitis, choroiditis or oculoglandular syndrome of Parinaud. We describe two patients with documented B. henselae infection and typical ocular compromise. Both patients were treated and had a favorable visual outcome.

ABSTRACT

The characteristic clinical presentation of cat scratch disease is subacute regional lymphadenopathy; nevertheless, 5-25 percent of Bartonella henselcie infections may present an atypical or systemic form, with potential eye involvement. We describe three clinical cases of ocular bartonellosis in two adolescents and one young adult, who had close contact with cats; all of them presented persistent fever ranging from 15 to 21 days, and two of them developed a sudden unilateral loss of visual acuity associated with optic neuritis. The other patient presented retinal choroiditis and unilateral retinal microgranulomas, with normal visual acuity. Patients received macrolides as sole antimicrobial or in association with rifampin, and one patient was additionally treated with systemic corticoids. The outcome was favorable in two patients; one patient developed a permanent visual deficit. Ocular bartonellosis must be suspected in patients with close contact to cats or with cat scratches whom develop persistent fever and sudden loss of visual acuity.


La enfermedad por arañazo de gato se manifiesta típicamente como una linfadenopatía regional sub-aguda; sin embargo, 5 a 25 por ciento de los pacientes infectados por Bartonella henselae desarrollan formas atípicas o sistémicas de la enfermedad, pudiendo evolucionar con compromiso ocular. Consideramos de interés describir las características clínicas, tratamiento y evolución de tres pacientes con bartonelosis ocular, dos adolescentes y un adulto joven, que tenían antecedentes de contacto y/o rasguño por gatos. Todos cursaron con síndrome febril prolongado, con 15 a 21 días de duración, asociado a pérdida súbita de la agudeza visual unilateral en dos casos, cuya fondoscopia reveló neuritis óptica. El otro paciente presentó retino-coroiditis y microgranulomas retiñíanos, con agudeza visual conservada. Todos recibieron tratamiento antimicrobiano con macrólidos solos o asociados a rifam-picina y uno recibió además corticosteroides sisté-micos. La evolución fue satisfactoria en dos, quedando un paciente con déficit visual permanente. Recomendamos sospechar bartonelosis ocular en pacientes con antecedentes de contacto y/o rasguños por gatos, que cursan con un síndrome febril prolongado y/o disminución súbita de la agudeza visual.

ABSTRACT

La enfermedad por arañazo de gato (EAG)es una enfermedad infecciosa, producida por Bartonella henselae, de curso benigno, que se presenta frecuentemente como adenopatía crónica en niños. En un 5 a 25 por ciento se puede manifestar de forma atípica, con compromiso óseo, abdominal, neurológico y oftalmológico. Presentamos 3 casos de EAG de curso atípico, con compromiso óseo confirmado con cintigrafía ósea y serología positiva para Bartonella henselae. Después de tratamiento antibiótico se obtuvo completa mejoría clínica.

ABSTRACT

Cat-scratch disease warrants extensive investigation, from an epidemiological, a diagnostic, but especially a therapeutic point of view. Two suggestive episodes of Bartonella henselae-caused cat-scratch disease are reported, and discussed in the light of the most recent literature evidence. The first case occurred in a 60-year-old man, thus suggesting that it is important to maintain an elevated level of suspicion for this disease in adults as well. Both episodes were characterized by a very prolonged and complicated disease course (with the involvement of three lymph node sets in the first case), a need for lymph-node drainage, and apparently negligible activity of many antimicrobial courses, with a very slow local cure. While specific culture and molecular biology techniques proved negative (probably due to late availability of appropriate clinical specimens), indirect immunofluorescence antibody assay was positive since the first weeks of disease, and elevated levels were also fond many months after disease onset. When clinicians face patients with prominent swelling of lymph nodes draining from the upper limbs, cat-scratch disease may be suspected on the grounds of epidemiological and clinical features, with a limited systemic involvement contrasting with a prominent local disease. The significance of specific antibody temporal kinetics in the subacute disease course is still unknown. Although biomolecular assays are now available, the time elapsed from disease onset to clinical diagnosis usually hampers diagnosis, while the roles of surgical debridement and of the unpredictable activity of antimicrobial chemotherapy warrant careful investigation.

ABSTRACT

Background: Cat-scratch disease is common among children. Among adults the disease is less often considered in the differential diagnosis of enlarged lymph nodes and fever. Aim: To report the clinical and laboratory features of eight patients with cat-scratch disease. Material and methods: Review of the medical records of eight patients (aged 22 to 57 years, six males) with a serological diagnosis of cat-scratch disease (an IgG titer over 1:256, by immunofluorescence). Results: Only five patients recalled having had contact with cats. Seven had fever and weight loss. Six had excessive sweating and five had chills. Seven had painfully enlarged lymph nodes mainly in submandibular and axillary regions. All had an increased C reactive protein and six had elevated erythrocyte sedimentation rate. Five had leukocytosis and four an elevated serum lactate dehydrogenase. The disease subsided in all, even in one patient that did not receive antimicrobials. Conclusions: Cat-scratch disease should be considered in the differential diagnosis of adult patients with lymph adenitis and fever.

ABSTRACT

Cat-Scratch disease is an infections pathology wich clinical manifestations are a pesistent benign lymphadenopaty, mild fever and malaise. This illness is recognized since 1931 but the microoganism wasn ït identified until 1988. The agent of this disease is gram negative bacterium named Bartonella henselac. A clinical case is presented of a female of 38 years old that presented a persistent enlargement of a submental nodule other systemic manifestations of this illness. This article sumarizes the relevant clinical manifestations, the diagnostics methods and the way to treat this disease

ABSTRACT

La enfermedad por arañazo de gato (EAG) ha sido reconocida con frecuencia creciente en nuestro medio. Si bien se presenta habitualmente como un cuadro benigno y autolimitado, 5 a 25 por ciento de los casos pueden presentar complicaciones sistémicas que incluyen, entre otras, manifestaciones viscerales, cutáneas y óseas. Debido al inusual compromiso óseo descrito en la literatura, consideramos de interés presentar un caso clínico de una osteomielitis costovertebral asociada a ESG y discutir el eventual beneficio de la terapia antibacteriana en esta enfermedad

ABSTRACT

La enfermedad por arañazo de gato (EAG) es una enfermedad infecciosa aguda benigna relativamente común, causada por Bartonella henselae. De los casos descritos sólo una pequeña proporción presenta compromiso extra nodal. Presentamos dos casos, una niña de 9 añosy un niño de 10 años. con EAG complicada por compromiso osteomielítico múltiple en vertebras, esternón, cráneo, pelvis y absceso paravertebral esplénico y linfadenopatía en uno de ellos, e importante compromiso vertebral con destrucción ósea en el otro. Se trataron con claritromicina y rifampicina en un caso, sólo con claritromicina en el otro. Ambos evolucionaron en mut buena forma con rápida mejoría clínica, radiológica y cintigráfica. Se analizan los casos y el manejo basado en la literatura publicada sobre EAG y esta inhabitual presentación con compromisos osteovertebrales múltiples

ABSTRACT

Numerosas afecciones son transmitidas al hombre por diferentes vectores, sean éstos insectos, pájaros o mamíferos. Entre las transmitidas por estos últimos, en la presente revisión se abordaron: la enfermedad por mordedura de rata que es básicamente un cuadro febril agudo, intenso, de comienzo brusco y de evolución recurrente y la enfermedad por rasguño de gato que se manifiesta por adenopatías sin signos inflamatorios locales, de lenta evolución regresiva y con escasa repercusión sobre el estado general. Ambas afecciones son más comunes en nuestro medio de lo que habitualmente se piensa y responden favorablemente a diversos antibióticos pero inicialmente plantean, con frecuencia, problemas de diagnóstico diferencial con enfermedades de pronóstico más grave
