ABSTRACT

We report a 70-year-old woman, who had recently consumed shellfish, that was admitted to the intensive care unit with septic shock and died 19 hours later due to a multi-organic failure. Microbiological, serological and molecular assays confirmed a hemolytic tdh+ Vibrio cholerae non-01, non 0139 as the etiologic agent (Rev Méd Chile 2009; 137: 1193-6).

ABSTRACT

Background: The clinical parameters for the suspicion of Clostridium difficile infections, namely the use of antimicrobials and diarrhea, have a low predictive value for the diagnosis. Aim: To search other clinical variables and determine a clinical prediction model for (Clostridium difficile diarrhea. Patients and methods: All patients to whom a Clostridium difficile study was requested, were prospectively studied during 5 months. Clinical variables of these patients were registered. The diagnosis of Clostridium difficile was done using the cytotoxicity test in fibroblast cultures. Results: Ninety two patients were analyzed and in 26, the diagnosis of Clostridium difficile was confirmed. A logistic regression model disclosed an age over 60 years old, the presence of mucus in the stools and a temperature over 37.8 ­C in the previous 24 h, as significant predictors of the infection. The correlation of the model, between the predicted probability and the observed condition, was 81.5 per cent. Conclusions: The presence of the clinical variables identified in this study are associated with a high probability of an infection by Clostridium difficile in patients with diarrhea and the recent use of antimicrobials

ABSTRACT

Clostridium difficile es el principal patógeno asociado a diarrea por uso de antibióticos y/o colitis psedomembranosa en pacientes hospitalizados. El diagnóstico se basa en la sospecha clínica y presencia de un test de laboratorio positivo para la detección de toxina de C. difficile, considerándose como confirmatorio el test de citotoxicidad. Recientemente se han introducido varios inmunoensayos que permiten el diagnóstico rápido; sin embargo, presentan sencibilidad y especificidad variables por lo que requiere ser evaluados por el método de referencia. El objetivo de este trabajo fue evaluar la correlación entre cinco inmunoensayos y el test confirmatorio de citotoxicidad. Para esto se estudiaron las muestras de deposiciones de 60 pacientes hospitalizados con sospecha clínica de diarrea por C. difficile mediante 4 inmunoensayos: 3 ELISA (ToxA Meridian©, Tox A Becton Dickinson© y Tox A + B TechLab© y 1 ensayo inmunocromatográfico tipo tarjeta: Inmunocard Tox A Meridian©. Cuarenta y seis muestras de las 60 se evaluaron por un test tipo tarjeta de reciente introducción: C. difficile ToxA Oxoid©. Como test confirmatorio se consideró el test de citotoxicidad. La sencibilidad fueron respectivamente: para ToxA Meridian© 95,7 y 78.8 por ciento, Tox A Becton Dickinson© 100 y 94,4 por ciento, Tox A + B TechLab© 91.3 y 86,5 por ciento. Inmunocard Tox A Meridian© 87 y 94,6 por ciento y C. difficile ToxA Oxoid© 94,7 y 96,3 por ciento. De acuerdo a los resultados, los test más recomendables serían Tox A Becton Dickinson© y C. difficile ToxA Oxoid©. Según el equipamiento y requerimientos de tiempos de respuestas de cada laboratorio, se debe establecer el tipo de inmunoensayo a utilizar
