Abstract
Durante la última década hemos presenciado un aumento de la cantidad de datos relativos a la presencia de translocación bacteriana en los modelos experimentales de cirrosis. Sin embargo, los estudios clínicos se han visto limitados por la falta de métodos no invasivos para estudiar dicho fenómeno. En los últimos años, las investigaciones realizadas en nuestro laboratorio se han centrado en la detección del ADN bacteriano en el suero y el líquido ascítico de los pacientes con cirrosis y ascitis estéril, y en las implicaciones clínicas que ello conlleva. Al principio, gracias a un método basado en la reacción en cadena de la polimerasa (PCR) y el secuenciamiento automatizado de nucleótidos, pudimos detectar e identificar la presencia de fragmentos de ADN bacteriano en dichos pacientes con ascitis no neutrocítica y con cultivo negativo. Desde entonces hemos acumulado una serie de datos que indican que la presencia de ADN bacteriano podría desempeñar un papel importante no sólo como marcador de translocación bacteriana, sino también como factor pronóstico a corto plazo. Expondremos aquí el pasado, el presente y el futuro de esta línea de investigación.
During the last decade, we have witnessed an increase in the amount of data related with the presence of bacterial translocation in experimental models of cirrhosis. However, clinical studies have been limited by the lack of non-invasive methods to study this phenomenon. Over the past years, the research developed in our laboratory has been focused on the detection of bacterial DNA in serum and ascitic fluid of patients with cirrhosis and sterile ascites, the clinical and immunological implications of such finding. Initially, by means of a polymerase chain reaction (PCR)-based method and automated nucleotide sequencing, we were able to detect and identify the presence of fragments of bacterial DNA in the mentioned patients with culture-negative, non-neutrocytic ascites. Since then, we have accumulated a core of data suggesting that the presence of bacterial DNA may have an important role not only as a marker of bacterial translocation, but also as a short-term prognostic factor. Here, we discuss the past, present and future of this line of investigation.
