ABSTRACT

RESUMEN La larva migrans visceral es una enfermedad que se produce al ingerir huevos infectantes de nematodos parásitos de gatos y perros (Toxocaracanis y Toxocaracati); los cuales eclosionan en el intestino del hombre y las larvas se distribuyen en todo el organismo, principalmente hígado, pulmón, corazón y cerebro. Las larvas en su migración dejan trazos de hemorragias, necrosis y células inflamatorias; algunas son destruidas por la respuesta inmune del huésped y otras forman granulomas eosinofílicos. Los síntomas dependen del tejido u órgano afectado, de la intensidad de la infección y del grado de la respuesta inmunológica inducida. Se presenta un caso del sexo masculino de 72 años que ingresa en el Servicio de Medicina del Hospital Militar Docente “Dr. Mario Muñoz Monroy”, de Matanzas, por cuadro de fiebre, diarreas, tos seca, astenia, anorexia y pérdida de peso al que se le diagnosticó larva migrans visceral. Por lo atípico de la edad del paciente y la complejidad del diagnóstico decidimos presentar este caso (AU).


ABSTRACT Visceral larva migrans is a disease produced after the ingestion of infectant eggs of cat´s and dog´s nematode parasites (Toxocara canis and Toxocara cati). These parasites harch in the men´s intestines and the larvas are distributed around the organism, mainly in the following organs: liver, lungs, hearth and brain. In their migration, the larvas leave traces of hemorrhage, necrosis and inflammatory cells; several of them are destroyed by the host´s immune answer and others form eosinophilic granulomas. The symptoms depend on the affected tissue or organ, on the infection intensity and on the level of induced immunologic answer. The case of a male patient, aged 72 years-old is presented. He entered the Medicine Service of the Teaching Military Hospital “Dr. Mario Muñoz Monroy”, of Matanzas with fever, diarrhea, dry cought, asthenia, anorexia and weight loss.Visceral larva migrans was diagnosed. The presentation of the case was decided because of the atypical patient´s age and the complexity of the diagnosis (AU).

ABSTRACT

BACKGROUND/AIMS: Visceral larva migrans, caused by Toxocara canis and Toxocara cati, has emerged as a significant cause of eosinophilic liver abscess (ELA). Differentiation of ELA associated with toxocariasis (ELA-T) from metastasis or primary liver malignancy is sometimes difficult. However, the role of albendazole treatment remains uncertain in this condition. The aim of this study was to evaluate whether albendazole can enhance the radiologic resolution of ELA-T. METHODS: We retrospectively reviewed the medical records of the patients diagnosed with ELA-T at our institution between January 2008 and December 2011. ELA-T was diagnosed based on the imaging findings on computed tomography or magnetic resonance imaging and the presence of positive serum IgG antibody for Toxocara canis. Among a total of 163 patients, 32 patients received albendazole (albendazole group) and 131 did not (control group). Baseline characteristics and fate of liver nodules were compared between the two groups. RESULTS: Baseline characteristics (age, sex, number and maximal size of lesions, eosinophil count) were similar between the two groups. Median duration for achieving radiologic resolution in the albendazole group was significantly shorter than in the control group (207 days [range 186-228] vs. 302 days [range 224-380], p=0.023). In Cox regression analysis of the cumulative rates of radiologic resolution, the hazard ratio for albendazole treatment was 1.99 (95% confidence interval, 1.22-3.23). CONCLUSIONS: Radiologic resolution of ELA-T can be accelerated with albendazole treatment. Hence, inconvenience associated with long-term follow-up and unnecessary worries among patients can be eliminated with albendazole treatment.

ABSTRACT

Human toxocariasis is caused by the presence of die larvae of Toxocara canis in the human host. It is a systemic disease that can have a sub-clinical course or can present under various clinical conditions. Most of the affected cases are young children under 5 years of age but the disease can affect adults. The diagnosis is done by the presence of the clinical features and/or by serologic tests. The treatment consists of the administration of anti-helmithic drugs in un-complicated cases in addition to corticosteroids in some cases. We are not aware of any studies about tins disease in Libya. Since the climatic conditions in some of the coastal parts of the country are appropriate to the maturation and survival of the larvae we think that this disease should be considered in the differential diagnosis ofeosinophilia specially in children

ABSTRACT

Larva migrans visceral é uma infecção universal que ocorre mais frequentemente em crianças menores de 10 anos de idade, caracterizada por febre, hepatomegalia, doença pulmonar e eosinofilia. O agente é o ascaris intestinal de cães e gatos. O benefício das drogas anti-helmínticas não está definido. O tratamento com tiabendazol, albendazol ou mebendazol está indicado nas complicações da doença. A transmissão da infecção pode ser prevenida estimulando as crianças a lavarem suas mãos após brincarem em áreas onde há cães

ABSTRACT

A 24-year -old woman 2-3 months after a normal parturation presented geophagy. Due to hypermenorrhea she consulted a gynecologist and in a hemogram a 57 percent (6, 893 x mm3) hypereosinophilia was detected. A chest TAC showed bilateral pulmonary nodules. The following tests resulted positive: ELISA IgG for toxocariasis 1: 1000, isohemagglutinins anti A 1:2048 and anti B 1:512. The patient was treated with albendazole and prednisone during 10 days. One month after treatment eosinophilia decreased to 2.590 x mm3 and ELISA IgG for toxocariasis descended to 1:128. Different aspect of human toxocariasis are commented. When hypereosinophia is observed in adult patients, toxocariasis must be checked

ABSTRACT

We relate a case of an 18-year-old man, resident of Xapuri (state of Acre, Brazil), with a history of repeated episodes of meningoencephalitis (three in one year), each one was examined by a local doctor. In our service (Emílio Ribas Institute of Infectology) we observed a patient with polyjoint aches, radiological and bronchoscopic pulmonary alterations (without clinical features), meningeal and brain stem manifestations--with normal brain computed tomography and cerebrospinal fluid. Blood eosinophils and serological Toxocara canis test (ELISA) were greatly increased. With the hypothesis of Toxocariasis (visceral larva migrans) we administered thiabendazole that brought complete clinical and laboratory remission. Inspite of a new episode of headache with meningeal manifestation approximately one month later (treated with dexamethasone resulting in a full remission after three days) we have not found other manifestations in approximately three and a half years of ambulatory care.

ABSTRACT

Para realizaçäo deste trabalho foram utilizados 45 camundongos da linhagem C57B1/6, divididos em 2 grupos, sendo o do Grupo I com 30 animais e do GrupoII com 15 animais. Cada animal foi inoculado com 10ü ovos infectantes de Toxocara canis, via oral, através de uma sonda introduzida diretamente no esôfago. Os ovos utilizados como inóculo foram obtidos por dissecaçäo de exemplares fêmeas do parasito e mantidos em soluçäo formaldeído a 1(pôr cento), por um período de 40 dias, até a obtenção do estágio infectante. Os animais do Grupo I foram submetidos a tratamento com Albendazol após o 7º dia de infecçäo, na dosagem de 400mg/Kg/dia, por via oral, durante 30 dias. Os camundogos do Grupo II(grupo controle) näo foram tratados com a droga. No 5§ dia após o término do tratamento, todos os animais foram necropsiados sendo examinados cérebro e olhos através da técnica de compressäo entre lâminas, ao microscópio óptico. Foi observado nível de eficácia de 76,36(pôr cento). Concluímos que o esquema terapêutico utilizado neste experimento foi ineficaz no tratamento da Toxocaríase experimental

ABSTRACT

Foram empregados 68 camundongos isogênicos da linhagem C57BL/6, divididos em 5 grupos. Grupos I,II e III com 18,10 e 10 animais, tratados com Ivermectin nas dosagens de 200, 400 e 800 ug/kg, respectivamente e grupos IV e V, com 20 e 10 animais näo tratados (grupos controle). Cada animal foi inoculado oralmente com 10ü ovos de Toxocara canis, empregando-se uma sonda esofagiana. O material utilizado como inóculo foi obtido por dissecaçäo de exemplares fêmeas do parasito, mantido em soluçäo de formol a 1 pôr cento, por um período de 40 dias, até a obtençäo do estágio infectante. O Ivermectin, diluído em propilenoglicol, foi administrado por via subcutânea, no 8§ dia após inoculaçäo (DAI). Todos os animais foram necropsiados no 23§ DAI, sendo examinados cérebro e olhos através da técnica de compressäo entre lâminas. Entre os animais tratados nas concentraçöes de 200, 400 e 800 ug/kg foram observados níveis de eficácia de 54,02 pôr cento, 54,76 pôr cento e 55,44 pôr cento, repectivamente. Apesar do pequeno número de animais empregados, pode-se inferir que os esquemas terapêuticos utilizados neste experimento foram ineficazes no tratamento da larva migrans murina experimental

ABSTRACT

Los autores presentan cinco casos de Toxocariasis ocular, cuatro de elllos con test de ELISA positivos con títulos variables entre 1/8 y 1/32. Tres niñas y dos varones con edades extremas entre los 8 y los 59 años de edad. Ninguno de los casos presentó previamente manifestaciones imputables a alguna localización del Síndrome de Larva Migrans Visceral. Todos coincidentemente presentaron su localización en el ojo izquierdo; con una evolución entre pocos meses a diez años. Tanto el Caso N§1, como el N§3 y el N§5 presentaron la forma clínica N§3 de la clasificación adoptada por Wilkinson y Col. (23). El Caso N§2 de nuestro casuística correspondería a la forma clínica N§2 del autor citado anteriormente; aunque casuística correspondería a la forma clínica N§2 del autor citado anteriormente; y el Caso N§4 podría equipararse al descripto por Gass (11) en 1978 como un Síndrome de Neuroretinitis Unilateral Subaguda Difusa, y que en 1983 demostró que el síndrome era causado por la larva del toxocara en forma directa o por su acción tóxica. Todos recibieron medicación con Thiobendazole entre 25 a 50 mg/Kg/día, asociado a prednisolona entre 40 a 60 mg/día. Un solo caso mostró intolerancia a la primera droga lo que abligó a suspender la medicación. Solo los casos N§1 y N§4 demostraron una mejoría evidente de la agudeza visual, en el último de ellos se sumó además la desaparición total de la sintomatología. En ninguno de los casos apareció leucocitosis; ni eosinofilia significativa (salvo en el caso N§1). Un solo paciente residía en el medio rural (Caso N§1) y otro en zonas periféricas de la ciudad (Caso N§3). Ccontacto evidente y franco con cachorros lo presentaron los casos N§1, N§2 y N§3. Casos N§4 y N§5 contacto ocasional con perros. Casos N§1 y N§3 antecedentes de geofagia

ABSTRACT

Das síndromes eosinofílicas, a Larva Migrans Visceral näo deve ser täo infrequente em nosso meio. Com este trabalho, queremos enfatizar a importância do diagnóstico de Larva Migrans Visceral, uma vez que se trata de uma patologia de bom prognóstico, e de tratamento que se mostra eficaz. Com isto há possibilidade de esclarecimento dos sintomas crônicos do paciente, muitas vezes tratatados inadequadamente e sem sucesso, como pneumonia e/ou crise de asma
