RESUMO

Se conocen los puntos precisos de intervención en la cadena epidemiológica para prevenir el Síndrome Urémico Hemolítico, pero las condiciones pueden variar entre distintas localidades. OBJETIVOS: Con este estudio se pretende mostrar la utilidad de un modelo de diagnóstico de situación que permite optimizar la implementación de un programa preventivo de educación comunitaria de tipo “formación de formadores” en dos municipios de la provincia de Buenos Aires, y una evaluación de procesos. MÉTODO: El diagnóstico incluyó el relevamiento de la situación socio-sanitaria, hábitos y costumbres alimentarios y detección de los problemas en la cadena de producción, comercialización y consumo de alimentos. La evaluación del proceso fue cuali-cuantitativa: número de talleres y de participantes, e indagación de fortalezas y debilidades del proceso. RESULTADOS: Los principales problemas encontrados fueron la carencia de agua potable y de manejo de las excretas en un gran porcentaje de la población y los deficientes controles bromatológicos y de mantenimiento de la cadena de frío en la provisión de carne y leche. Este diagnóstico permitió adaptar el programa a las condiciones específicas locales, elemento necesario para lograr una intervención eficaz. Se realizaron en total 26 talleres con la participación de 588 agentes. El material gráfico fue de gran utilidad para la comprensión de los contenidos docentes y todos los participantes de los talleres respondieron con gran motivación. Se logró el apoyo de las autoridades locales, lo que facilitó la ejecución del programa


The precise points of intervention in the epidemiological chain to prevent Hemolytic Uremic Syndromeare well known, although conditions may vary between different localities. OBJECTIVES: This study aims to show the usefulness of a situation diagnostic model to optimize the implementation of a preventive community education program type “training the trainers” in two municipalities in the province of Buenos Aires, and the evaluation of the process. METHODS: The diagnosis included a survey of the socio-sanitary conditions, food habits and identifying problem sin the chain of production, marketing and consumption of food. Process assessment was qualitative and quantitative: number of workshops and participants, and determination of strengths and weaknesses of the process. RESULTS: The main concerns were: lack of safe water and excreta management in a large percentage of the population, weak bromatological controls and maintenance of cold chainin providing meat and milk. This diagnosis allowed to adaptthe program to specific local conditions, which is necessary to achieve effective intervention. A total of 26 workshops involving 588 agents were carried out. The artwork was useful for the understanding of educational contents and all workshop participants responded with great motivation. The support from local authorities facilitated the implementation of the program

RESUMO

We evaluated risk factors for sporadic Shiga toxin-producing Escherichia coli (STEC) infection among children in Argentina. We conducted a prospective case-control study in 2 sites and enrolled 150 case-patients and 299 controls. The median age of case-patients was 1.8 years; 58% were girls. Serotype O157:H7 was the most commonly isolated STEC. Exposures associated with infection included eating undercooked beef, living in or visiting a place with farm animals, and contact with a child <5 years of age with diarrhea. Protective factors included the respondent reporting that he or she always washed hands after handling raw beef and the child eating more than the median number of fruits and vegetables. Many STEC infections in children could be prevented by avoiding consumption of undercooked beef, limiting exposure to farm animals and their environment, not being exposed to children with diarrhea, and washing hands after handling raw beef.

RESUMO

Chronic renal failure (CRF) is the most severe complication of hemolytic uremic syndrome (HUS). In 1996, the histological sequence of changes in patients with long lasting oligoanuric periods was clarified. In the last years different therapeutic schemes have been proposed in order to slacken the development of terminal CRF in different renal conditions secondary to diabetes and other diseases. Some of these cases can suffer the onset of renal failure at adolescence. In this review, response to two treatment schemes in different patients with HUS and proteinuria with or without hypertension or renal failure is commented. Early indication of poor sodium diet and strict control of protein intake at the very moment of hospital discharge is strongly recommended, as well as angiotensin II conversion inhibiting enzymes (iACE) at the appearance of proteinuria.

RESUMO

We evaluated the relationship between the acute phase and the development of end-stage renal disease (ESRD) and the outcome of renal transplant in patients with Shiga toxin-associated hemolytic uremic syndrome (Stx-HUS). A 20-year retrospective study was performed of 66 renal transplants in 62 patients with Stx-HUS compared with 189 renal allografts in 178 children with other diseases. Of 62 patients, 61 had >7 days of oliguria during the acute phase. Stx-HUS patient survival was not different from controls (92% vs. 83% 15 years after renal transplantation). In the cyclosporine (CsA) era, survival of grafts from living related (LRD) and cadaver (CD) donors in Stx-HUS and control patients was 83% versus 70% ( P<0.03) and 77% versus 49% ( P<0.05) at 10 years. Graft survival in Stx-HUS and dysplasia/obstructive uropathy patients was 79% versus 76% ( P=NS), but it was different from that of other diseases (79% vs. 58%, P<0.001). There was no clinical or histopathological evidence of Stx-HUS recurrence. In conclusion, in Stx-HUS patients the duration of the acute oliguric period was a good predictor for the progression to ESRD. Use of CsA and the absence of recurrence of the disease influenced the excellent prognosis in Stx-HUS patients after renal transplantation. The development of ESRD in Stx-HUS could be mediated by non-immunological factors.

RESUMO

Evaluamos un nuevo derivado oxazolínico de la prednisona comparando su respuesta y efectos secundarios con los observados en el tratamiento clásico con prednisona, en un grupo de 24 niños durante el primer episodio de Síndrome Nefrótico Idiopático. Grupo A: 12 niños de edad media: 43 meses (r: 10 á 72 m) recibieron deflazacort en dosis de 1.8 á 2.2 mg/kg/día durante 30 días contínuos y 30 días alternos (serie completa). Grupo B: 12 niños, edad media: 37 meses (r: 29 á 70) recibieron metilprednisona a la dosis de 1.5 á 1.7 mg/kg/día con igual esquema que los del grupo A. En 6 pacientes del Grupo A la proteinuria desapareció entre los 7 y 26 días de tratamiento (x 13.8 d). Los otros 6 no negativizaron la proteinuria. En 7 niños del Grupo B la proteinuria remitió entre 5 y 15 días (x 10.5 d), los 5 restantes persistieron con proteinuria masiva hasta la finalización de la primera serie de tratamiento. Los parámetros bioquímicos pre y post tratamiento en los pacientes corticosensibles no mostraron diferencias significativas entre ambos grupos. Los valores de colesterol fueron menores en los que recibieron deflazacort aunque sin significancia estadística. Los efectos esteroides colaterales estuvieron presentes en la mayoría de los niños tratados con prednisona, y fueron significativamente menores en los que recibieron deflazacort (AU)
