Sobrediagnóstico microscópico de amebiasis intestinal: encuesta a técnicos de laboratorio
María de los ángeles Fernández Ferrer,Lizet Sánchez Valdez,Humberto Marín Iglesias,Ivón Montano Goodridge
Revista Cubana de Investigaciones Biom??dicas , 1999,
Abstract: Empleando ENZYMEBA, procedimiento diagnóstico de amebiasis intestinal desarrollado en el Instituto de Medicina Tropical "Pedro Kourí", se demostró que en la provincia Cienfuegos el examen microscópico de heces se asocia con un marcado sobrediagnóstico de esta parasitosis (de 424 muestras positivas a Entamoeba histolytica, por examen microscópico, solo 61 lo fueron por ENZYMEBA). Para incursionar en los factores que podrían estar incidiendo en la calidad del trabajo de los técnicos de laboratorio de esta provincia se aplicó a la casi totalidad de ellos ( 96 de 102) un cuestionario (23 preguntas) sobre diversos aspectos relacionados con este tipo de diagnóstico. El conjunto de los resultados de esta encuesta sugiere que en la calidad del diagnóstico de amebiasis intestinal por examen microscópico podría estar incidiendo, además de deficiencias técnico-organizativas y materiales, una insuficiente preparación teórica de quienes la realizan. By using ENZYMEBA, a disgnostic procedure of intestinal amebiasis devoloped at the "Pedro Kourí"Institute of Tropical Medicine, it was proved that in the province of Cienfuegos the microscopic feces test is associated with a marked overdiagnosis of this parasitosis (of 424 samples positive to Entamoeba histolytica by microscopic examination, only 61 proved to be positive by ENZYMEBA). To determine the factors influencing on the quality of the lab technicians′work in this province, most of these technicians (96 of 102) answered a questionnaire containing 23 questions on different aspects related to this type of diagnosis. The results of this survey suggest that in addition to the technical, organizational, and material deficiencies the inadequate theoretical training of those who make the test may also influence on the quality of the diagnosis of intestinal amebiasis by microscopopic examination.

Abstract: Empleando ENZYMEBA, procedimiento diagnóstico de amebiasis intestinal desarrollado en el Instituto de Medicina Tropical "Pedro Kourí", se demostró que en la provincia Cienfuegos el examen microscópico de heces se asocia a un marcado sobrediagnóstico de esta parasitosis (de 424 muestras positivas a Entamoeba histolytica por examen microscópico sólo 61 lo fueron por ENZYMEBA). Para incusionar en los factores que podrían estar incidiendo en la calidad del trabajo de los técnicos de aquella provincia, aplicamos una encuesta al universo de los responsables de laboratorios de ésta. El conjunto de los resultados de la aplicación de este cuestionario (11 preguntas) nos sugiere que en la calidad del diagnóstico de amebiasis intestinal por examen microscópico de heces podrían estar incidiendo deficiencias técnico-organizativas asociadas a otros factores objetivos y subjetivos. Using ENZIMEBA, diagnostic procedure of intestinal amebiasis, developed in the Institute of Tropical Medicine "Pedro Kourí", it could be shown that in the Cienfuegos Province, the microscopic assay of feces, was associated to a marked superdiagnosis of this parasitosis (out of 424 Entamoeba histolytica positive sample by microscopic screenings, only 61 were positive ENZYMEBA samples). In order to know the factors that could be influencing on the quality of work of that province's technicians, we applied a survey to the universe of that province's laboratory personnel. The group of results from this survey (11 questions) suggest us that the quality of the intestinal amebiasis diagnosis, by microscopic screening of feces, could be affected by tecnnical and organizational defficiencis associated to other objective and subjective factors.

Revista Cubana de Investigaciones Biom??dicas , 2003,
Abstract: Se realizó un estudio en la provincia Cienfuegos, el cual demostró que el examen microscópico de heces se asociaba a un marcado sobrediagnóstico de amebiasis intestinal. Los resultados de encuestas aplicadas a responsables y técnicos de laboratorio relacionados con el diagnóstico microscópico de esta parasitosis, evidenciaron que el sobrediagnóstico podía estar asociado a deficiencias cognoscitivas y técnico-organizativas. Para contribuir al mejoramiento del diagnóstico microscópico del parasitismo intestinal, en general, y de la amebiasis intestinal, en particular, se ejecutó un grupo de acciones en la citada provincia. A 1 a o de completada la puesta en práctica de esas medidas, una segunda aplicación de las encuestas, permitió conocer de una significativa mejoría de los técnicos encuestados en la totalidad de los aspectos cognoscitivos evaluados. Sin embargo, tanto la encuesta aplicada a responsables de laboratorio como la aplicada a los técnicos, demostraron que subsisten la mayoría de las deficiencias técnico-organizativas detectadas antes de la intervención. In a study conducted in the province of Cienfuegos, it was demonstrated that the microscopic examination of feces was associated with a marked overdiagnosis of intestinal amebiasis. The results of the surveys done among the laboratory technicians having to do with the microscopic diagnosis of this parasitosis, and to those in charge of the laboratory, proved that the overdiagnosis may be connected with cognitive, technical and organizational deficiencies. To contribute to the improvement of the microscopic diagnosis of intestinal parasitism, in general, and of intestinal amebiasis, in particular, a series of actions were taken in this province. After a year, a second survey was done that showed a significant improvement of the surveyed technicians in all the evaluated cognitive aspects. However, the surveys applied to the lab technicians and to the personnel responsible for the laboratory demonstrated that most of the technical and organizational deficiencies detected before the intervention still exist.
Eficacia antiamebiana del metronidazol demostrada en un estudio realizado en la provincia de Cienfuegos

Revista Cubana de Medicina Tropical , 2002,
Abstract: Se realizó una serie de 3 estudios en la provincia de Cienfuegos para demostrar que la amebiasis intestinal en Cuba podría ser un problema de salud sobredimensionado. Con los 2 primeros, se demostraron 2 componentes de esta sobredimensión: el sobrediagnóstico microscópico y el desconocimiento de la presencia de Entamoeba dispar, especie no patógena, en mucho de los casos en que la observación microscópica fue correcta. Aquí se reportó el estudio que demuestra el tercer componente: la creencia errónea de que existe resistencia de Entamoeba histolytica al metronidazol. Para ello, a 35 individuos con infección por una o ambas especies del complejo E. histolytica / E. dispar se les administró metronidazol a la dosis de 250 mg 3 veces al día, durante 10 d. A muestras de heces colectadas inmediatamente después del tratamiento se les aplicó la prueba ENZYMEBA, para detectar la presencia de una o ambas especies del complejo E. histolytica / E. dispar, y un procedimiento de reacción en cadena de la polimerasa múltiple, para precisar la especie presente. Los resultados de la aplicación de estos ensayos permitieron comprobar la desaparición de la infección por E. histolytica en todos los casos y, por lo tanto, concluir que en aquella provincia, como posiblemente en el resto del país, el metronidazol continúa siendo una droga eficaz en el tratamiento de la amebiasis intestinal. Three studies were conducted in Cienfuegos province to prove that intestinal amebiasis in Cuba could be an overestimated health problem. The first two studies showed two components of this overestimation: microscopical overdiagnosis and lack of knowledge about Entamoeba dispar, a non-pathogenic species, in most cases in which microscopical examination was correct. This paper reported the third study that showed the third component: the wrong belief that Entamoeba histolytica is resistant to metronidazole. Thirty-five individuals infected with one or both species of E-histolytica-E.dispar combination were given metronidazole at a dose of 250 mg three times daily for 10 days. Stool samples taken immediately after the treatment were tested by ENZYMEBA to detect one or both species and by a multiplex polymerase chain reaction procedure to determine the existing species. The results of these assays revealed that E.histolytica infection disappeared in all the cases, therefore, we may conclude that in Cienfuegos province and probably in the rest of the country, metronidazol remains an effective drug in the treatment of intestinal amebiasis

Abstract: Se demostró, con el empleo de herramientas inmunológicas y biomoleculares, en un estudio realizado en la provincia de Cienfuegos, que en aquella provincia la amebiasis intestinal era un problema de salud sobredimensionado. Una encuesta sobre conocimientos, percepciones y prácticas aplicada a médicos relacionados con el diagnóstico, tratamiento y control de esta parasitosis evidenció que la sobredimensión podía estar asociada a una inadecuada percepción del problema y a un marcado desconocimiento que sobre importantes aspectos de esta entidad poseían. Para contribuir a la solución de la sobredimensión, y de sus consecuencias, se ejecutó un grupo de acciones en la citada provincia. A 1 a o de completada la puesta en práctica de esas medidas, una segunda aplicación de la encuesta, cuyos resultados se publican en este documento, permitió conocer de una significativa mejoría de los encuestados en la casi totalidad de los aspectos cognoscitivos (6,73 y 11,23 medias de respuestas correctas antes y después, respectivamente, de la intervención) y perceptuales evaluados. In a study conducted in the province of Cienfuegos, it was proved by using immunological and biomolecular tools that intestina amebiasis in that province was an overdimensioned health problem. A survey on knowledge, perceptions and practices applied to those physicians related to the diagnosis, treatment and control of this parasitosis showed that the overdimensioning may be associated with an inadequate perception of the problem and with a marked lack of knowledge about important aspects of this entity. To contribute to the solution of the ovedimensioning and of its consequences, a set of actions were taken in that province. After a year, a second survey was done, whose results are published in this document, allowing to know about a significant improvement of the surveyed in almost all the evaluated cognitive and perceptual aspects (6.73 and 11.23 means of correct answers before and after. the intervention, respectively).

Abstract: three studies were conducted in cienfuegos province to prove that intestinal amebiasis in cuba could be an overestimated health problem. the first two studies showed two components of this overestimation: microscopical overdiagnosis and lack of knowledge about entamoeba dispar, a non-pathogenic species, in most cases in which microscopical examination was correct. this paper reported the third study that showed the third component: the wrong belief that entamoeba histolytica is resistant to metronidazole. thirty-five individuals infected with one or both species of e-histolytica-e.dispar combination were given metronidazole at a dose of 250 mg three times daily for 10 days. stool samples taken immediately after the treatment were tested by enzymeba to detect one or both species and by a multiplex polymerase chain reaction procedure to determine the existing species. the results of these assays revealed that e.histolytica infection disappeared in all the cases, therefore, we may conclude that in cienfuegos province and probably in the rest of the country, metronidazol remains an effective drug in the treatment of intestinal amebiasis

Abstract: Se demostró, en un estudio previo realizado en la provincia de Cienfuegos, en el que se empleó ENZYMEBA, que en aquella provincia, el examen microscópico de heces para el diagnóstico de amebiasis intestinal se asociaba a falsos diagnósticos. Para conocer de los posibles factores asociados a este problema, se aplicó una encuesta a médicos de la provincia de Cienfuegos, relacionada con el diagnóstico y tratamiento de la amebiasis intestinal. Según el análisis de los resultados, las consecuencias adversas del sobrediagnóstico de amebiasis intestinal pudieran estar amplificadas por la ausencia de percepción del problema, y por el marcado desconocimiento que sobre importantes aspectos de esta parasitosis poseen. In a previous study conducted at the province of Cienfuegos with ENZYMEBA it was proved that the microscopic examination of stools for the diagnosis of intestinal amebiasis was associated with false diagnoses in that province. Physicians from Cienfuegos were surveyed in connection with the diagnosis and treatment of intestinal amebiasis to know the possible factors related to this problem. According to the analysis of the results, the adverse consequences of the overdiagnosis of intestinal amebiasis may be aggravated by the lack of perception of the problem and by their marked ignorance on important aspects of this parasitosis.
