ABSTRACT

Abstract Sarcoidosis is a rare multisystem chronic inflammatory disease in children. We present a case of a five-year-old child with clinical features mimicking several diseases, including tuberculosis. After failure of treatment based on the suspected diagnosis, an axillary lymph node biopsy showed noncaseating granulomas compatible with sarcoidosis and appropriate treatment was then started.

ABSTRACT

The strongyloidiasis is a parasitic disease that poses as a serious public health problem, mainly in tropical and subtropical countries. Over the years, some conditions, such as advances in corticosteroid treatment and immunosuppressive diseases, have improved not only the increase in cases of strongyloidiasis, but also the emergence of severe forms of the disease and / or deaths. For these reasons, the objective of this study is to make a critical analysis of the occurrence of strongyloidiasis in patients with comorbidities, describing clinical and epidemiological characteristics associated with these diseases that can highlight the importance of monitoring this parasitosis in most susceptible groups.


La estrongiloidiasis es una parasitosis que representa un grave problema de salud pública, principalmente en países ubicados en regiones tropicales y subtropicales. A lo largo de los años, algunas condiciones, como por ejemplo, avances en el tratamiento con corticosteroides y enfermedades que evolucionan con inmunosupresión, han favorecido no solamente al aumento de casos de estrongiloidiasis, sino también al surgimiento de formas graves de la enfermedad y/u decesos. Por lo expuesto, el objetivo del presente estudio fue realizar un análisis crítico de la ocurrencia de la estrongiloidiasis en portadores de co-morbilidades, describiendo las características clínico-epidemiológicas de esa asociación que puedan resaltar la importancia de vigilar esta parasitosis en grupos considerados más susceptibles.

ABSTRACT

In human toxocariasis, there are few approaches using immunological markers for diagnosis and therapeutic assessment. An immunoblot (IB) assay using excretory-secretory Toxocara canis antigen was standardized for monitoring IgG, IgE and IgA antibodies in 27 children with toxocariasis (23 visceral, three mixed visceral and ocular, and one ocular form) for 22-116 months after chemotherapy. IB sensitivity was 100 percent for IgG antibodies to bands of molecular weight 29-38, 48-54, 95-116, 121-162, >205 kDa, 80.8 percent for IgE to 29-38, 48-54, 95-121, > 205 kDa, and 65.4 percent for IgA to 29-38, 48-54, 81-93 kDa. Candidates for diagnostic markers should be IgG antibodies to bands of low molecular weight (29-38 and 48-54 kDa). One group of patients presented the same antibody reactivity to all bands throughout the follow-up study; in the other group, antibodies decayed partially or completely to some or all bands, but these changes were not correlated with time after chemotherapy. Candidates for monitoring patients after chemotherapy may be IgG antibodies to > 205 kDa fractions, IgA to 29-38, 48-54, 81-93 kDa and IgE to 95-121 kDa. Further identification of antigen epitopes related to these markers will allow the development of sensitive and specific immunoassays for the diagnosis and therapeutic assessment of toxocariasis.


Métodos imunológicos desempenham papel importante no diagnóstico da toxocaríase, entretanto há poucos estudos sobre marcadores diagnósticos e de acompanhamento terapêutico. Foi padronizado ensaio de immunoblot (IB) empregando antígeno de excreção-secreção de Toxocara canis para pesquisa de anticorpos IgG, IgE e IgA em 27 crianças com toxocaríase nas formas visceral (23), mista visceral e ocular (3) e ocular (1), por 22-116 meses após quimioterapia. Foram observados dois perfis de reatividade dos anticorpos: permanência contra todas as frações no decorrer do estudo; diminuição ou negativação contra algumas ou todas as frações, porém, essas mudanças não se correlacionaram com tempo de tratamento. A sensibilidade do IB foi 100,0 por cento para anticorpos IgG específicos para frações de massa molecular de 29-38, 48-54, 95-116, 121-162, > 205 kDa, 80,8 por cento para IgE específicos para 29-38, 48-54, 95-121, > 205 kDa e 65,4 por cento para IgA específicos para 29-38, 48-54, 81-93 kDa. Anticorpos IgG específicos para frações de baixa MM (29-38 e 48-54 kDa) podem ser sugeridos como candidatos a marcadores diagnósticos. Por sua vez, anticorpos IgG para fração > 205 kDa, IgA para 29-38, 48-54, 81-93 kDa e IgE para 95-121 kDa podem ser candidatos a marcadores terapêuticos. A identificação de epítopos antigênicos relacionados a estes marcadores poderá ser importante para o desenvolvimento de ensaios altamente sensíveis e específicos no diagnóstico e avaliação terapêutica da toxocaríase.

ABSTRACT

Strongyloidiasis, caused by Strongyloides stercoralis, consists of various clinical syndromes. Strongyloidiasis hyperinfection leads to morbidity and mortality particularly in immunocompromized patients. This study aimed to determine the risk factors for strongyloidiasis hyperinfection and clinical outcomes. The medical records for hospitalized patients infected with S. stercoralis at Ramathibodi Hospital during 1994-2005 were retrospectively reviewed. Risk factors for strongyloidiasis hyperinfection were determined. There were 123 episodes of strongyloidiasis in 111 patients. The mean age was 46.8 +/- 17.8 years; 61% were males. Of 123 episodes, 37 (30.1%) had strongyloidiasis hyperinfection; the others had chronic strongyloidiasis. All the patients with strongyloidiasis hyperinfection and 88.3% of those with chronic strongyloidiasis were immunocompromized (p = 0.032); 89.2% of the former and 55.8% of the latter had received corticosteroids (p < 0.001). There were no significant differences in the type of immunocompromized host and the corticosteroid dosage between the two groups (p > 0.05). The hyperinfection group had a lower mean serum protein (p = 0.026) and albumin (p = 0.027) but a higher frequency of sepsis (p = 0.029), asthma-like symptoms (p = 0.025), adult respiratory distress syndrome (p = 0.026), and a longer duration of treatment (p=0.004). By logistic regression, corticosteroids use was a risk factor for hyperinfection (OR = 6.5, 95% CI = 2.1-20.0, p = 0.001). Most of the patients were treated with albendazole or thiabendazole, with a cure rate of 76.9%, whereas other recent cases treated with ivermectin had an average cure rate of 83.3%. The overall mortality rate was 8.1%.

ABSTRACT

A gastroenterite eosinofílica (GE) é considerada uma doença pouco comum, com menos de 300 casos relatados na literatura. É caracterizada por infiltração eosinofílica das camadas da parede do tubo digestivo. A patogênese não é bem conhecida. Há algumas evidências da participação de fatores imunológicos ou alérgicos. Em geral, o prognóstico é favorável, embora a doença tenha caráter recorrente. Relata-se o caso de paciente, 21 anos, sexo masculino/ que apresentou quadro de dor abdominal, náusea, vômitos, emagrecimento e eliminação reduzida de flatos e fezes. Ao exame físico, foram observadas distensão abdominal, dor à palpação e ascite tensa. Os exames laboratoriais demonstraram eosinofilia no sangue periférico, variando de 15 a 60%. Exames parasitológicos de fezes seriados não mostraram ovos ou larvas. Ao estudo radiológico, identificaram-se espessamento da parede do intestino delgado e redução do lume. Infiltração eosinofílica da mucosa do cólon distal foi verificada pelo exame anatomopatológico. Com base nesses achados, o diagnóstico de GEfoi realizado e instituído o tratamento com prednisona, ocorrendo remissão da doença. Apesar de ser considerada doença rara e de causa ainda desconhecida, a GEdeve ser incluída no diagnóstico diferencial dos quadros de eosinofilia periférica com comprometimento do trato gastrintestinal (TGI).

ABSTRACT

La estrongiloidiosis es una enfermedad parasitaria intestinal causada por S. stercoralis, un nemátode geohelmíntico altamente prevalente en zonas tropicales y subtropicales. El tratamiento de elección actual es ivermectina, y como segunda alternativa el tiabendazol disponible en algunas instituciones de salud en el Perú. Nuestro objetivo fue evaluar la eficacia y tolerabilidad de tiabendazol (25 mg/kg/día) repartido dos veces al día después de las comidas por 3 días, en individuos con infección crónica por S. stercoralis. El estudio fue llevado a cabo en el Hospital de La Merced, provincia de Chanchamayo, Perú (zona endémica); en un periodo de 90 días. El estudio incluyó a 32 individuos (22 mujeres - 10 hombres; media de edad más menos DS = 9.34 más menos 8.11 años) con diagnóstico parasitológico de S. stercoralis. Los exámenes de seguimiento fueron recuentos de eosinófilos, hematocrito, cultivo de heces en placas de agar nutritivo y Método de Baermann en Copa (técnica modificada por Lumbreras). La tasa de curación fue de 90.6 por ciento. La media de eosinófilos en los pacientes curados disminuyó significativamente (1168 a 665 eosinófilos/cc, p=0.006) en comparación con el grupo de pacientes que fracasaron al tratamiento cuya media de eosinófilos tuvo un ligero aumento (61 a 897 eosinófilos/cc, p=0.125). En ambos grupos, el hematocrito aumentó entre 2 por ciento y 3 por ciento. Los efectos adversos fueron cefalea, mareos y epigastralgia en el 6.2 por ciento de los pacientes. Concluimos que el esquema evaluado tiene una alta tasa de efectividad y fue bien tolerado, y podría ser tomado en cuenta en programas de control para zonas hiperendémicas de este parásito.


Strongyloides stercoralis infection is a disease caused by an intestinal parasite. This helminth is highly prevalent in tropical and subtropical areas. The preferred treatment is ivermectin, and tiabendazole as a second option available in certain Peruvian institutions. The purpose of the study was to assess the efficacy and tolerability of tiabendazole (25 mg/kg/day) administered twice a day (after meals) for three days in individuals with S. stercoralis chronic infection. The study was conducted at Hospital de La Merced, Province of Chanchamayo, Peru (endemic area), during a 90 day period. The study included 32 individuals (22 female and 10 male, average age ± SD = 9.31 ± 8.11 years) with a diagnosed S. stercoralis infection. Follow up tests were eosinophil count, hematocrit, agar plate feces culture, and Baermann technique modified by Lumbreras. Healing rate was 90.6 per cent. The average eosinophil count in healed patients significantly decreased (1168 to 665 eosinophils/cc, p=0.006) as compared to the treatment failure group, which showed a slight increase (618 to 897 eosinophils/cc, p=0.125). Hematocrit increased in both groups (2% and 3%, respectively). Adverse effects were headache, dizziness, andepigastralgia in 6.2 per cent of individuals. It was concluded that the studied scheme showed a high effectiveness rate and was well tolerated. Therefore this scheme maybe taken into account for control programs of this parasite in hyperendemic areas.

ABSTRACT

A infecção pelo Strongyloides stercoralis em associação com imunosupressão pode manifestar-se com lesões em múltiplos órgãos e sistemas, caracterizando a forma disseminada da doença. Lesões cutâneas não são freqüentemente relatadas e, se presentes, manifestam-se como rash e petéquias. Púrpuras bem definidas são pouco descritas. No presente trabalho é descrito um caso de estrongiloidíase disseminada, com acometimento cutâneo em forma de púrpura, que se desenvolveu em um paciente timectomizado e usuário crônico de corticosteróide devido à miastenia gravis.

ABSTRACT

Estudou-se a recuperação de larvas na fase crônica de camundongos infectados por Toxocara canis, bem como a presença de anticorpos anti-Toxocara após tratamento com ivermectina, mebendazol ou tiabendazol, durante cinco dias consecutivos. Os animais foram sangrados pelo plexo retroorbitário entre 30 e 270 dias após a infecção (DPI). Os soros foram processados pela técnica de enzyme linked immunosorbent assay (ELISA) para pesquisa de anticorpos da imunoglobulina da classe G (IgG), utilizando antígeno ES de T. canis. Aos 270 DPI, os animais foram sacrificados para recuperação de larvas no sistema nervoso central, no fígado, nos pulmões e músculos. Os resultados do teste imunoenzimático indicam que, aos 20 dias após tratamento (50 DPI), o nível de anticorpos anti-Toxocara IgG aumentou nos três grupos tratados, mantendo-se elevado ao longo do experimento até o 270º DPI. Em relação aos animais infectados e não-tratados, observou-se decréscimo significativo no número de larvas recuperadas nos animais dos três grupos tratados, não se conseguindo a cura parasitológica. Com este estudo conclui-se que as três drogas utilizadas no experimento têm eficácia similar.

ABSTRACT

Tungiasis is caused by the penetration of the female sand flea Tunga penetrans into the epidermis, and subsequent hypertrophy of the parasite. In most cases lesions are confined to the feet. During a cross-sectional study, an unusual case of ectopic tungiasis in the inguinal area was detected. Histological examination of tissue samples showed a remarkable pseudoepitheliomatous aspect of the epidermis. Clinical features and differential diagnoses are discussed.

ABSTRACT

OBJETIVO: Evaluar la prevalencia e intensidad de las infecciones por geohelmintos en niños de dos comunidades hiperendémicas tratadas con técnicas antihelmínticas diferentes: una con tratamiento selectivo o individual, y la otra con tratamiento masivo reiterado. MÉTODOS: La población estuvo compuesta por 909 niños de uno u otro sexo, con edades entre 2 y 13 años, que vivían en dos comunidades marginales de la ciudad: Las Lomas y El Abasto, Santa Fe, Argentina. Se realizó un trabajo prospectivo longitudinal, cuasiexperimental, de comunidades. Durante los 22 meses del estudio se llevaron a cabo 5 controles parasitológicos, evaluados desde el punto de vista cualitativo y cuantitativo, y se dispensaron tratamientos antihelmínticos después de los controles 0, 2, 3 y 4. En Las Lomas se aplicó el tratamiento selectivo a los casos con diagnóstico parasitológico positivo que integraban la muestra A (n = 55) y en El Abasto, tratamiento masivo a todos los niños, incluidos los integrantes de la muestra B (n = 50). Ambas muestras fueron escogidas para realizar los controles. RESULTADOS: Se comprobó una prevalencia e intensidad de la infección por Ascaris lumbricoides significativamente mayor en El Abasto. No se detectaron diferencias para Trichuris trichiura. Al comparar las prevalencias y cargas parasitarias de A. lumbricoides entre los controles realizados dentro de una misma comunidad (inicio y final del estudio) no se observaron diferencias significativas en la muestra A, aunque sí en la muestra B. En cuanto a T. trichiura, se detectaron diferencias significativas entre ambos controles en las dos muestras. CONCLUSIONES: Solo el tratamiento masivo y reiterado logró disminuir eficaz y significativamente la prevalencia y la carga parasitaria de A. lumbricoides durante el período estudiado

ABSTRACT

Infection by human T-cell lymphotropic virus type I (HTLV-I) is associated with neurological diseases, malignancies, and other less commun pathologies. In addition, infection by HTLV-I has been implicated in some degree of immunological impairment. Some previous reports detected an association between HTLV-I infection and an increased rate of antibodies against S. stercoralis, as well as a higher frequency of S. stercoralis carrier state. Here, we report a case of a chronic, recurrent S. stercoralis parasitism in a patient infected by HTLV-I. The patient demonstrated evidence of immunosupression characterized by skin allergy to commun antigens, oral candidiasis and severe, recurrent diarrhea caused by S. stercoralis. The infection requires maintenance of supressive therapy to control diarrhea and its consequences. We postulate that S. stercoralis may act as an opportunistic agent in patients infected by HTLV-I.

ABSTRACT

Patients with AIDS are prome to develop infections caused by opportunistic pathogens. Unusual agents, such as Stongyloides stercoralis, are being described in this syndrome, resulting in disseminated disease which is always severe and, in some cases, fatal. We describe a case of patient with AIDS and Strongyloides stercoralis infection involving the gastrointestinal tract and lungs. Therapy with thiabendazole for ten days led to resolution of the acute episode. Preventive therapy with 3g of thiabendazole once a week was then prescribed, and repeated fecal examinations were negative for larvae. Following discontinuation of treatment, however, the patient again had a positive fecal examination for Strongyloides stercoralis larvae, even though reinfection was considered to be very unlikely. The patient was retreated with a shorter course of therapy and once per week preventive therapy was reintroduced. After four months of follow-up, repeated fecal examinations were negative. When the treatment was changed to thiabendazole given once every two weeks, however, pulmonary Strongyloides stercoralis recurred. Subsequently, because of intolerance to thiabendazole, the patient was treated with cambendazole. The patient died three months later due to Pseudomonas aeruginosa pneumonia. Prolonged therapy for Strongyloides stercoralis infection may be necessary. Although further evaluation is needed, 3g of thiabendazole once a week may be adequate for this purpose. Cambendazole may be a useful alternative for disseminated Strongyloides stercoralis.
