RAPID DIAGNOSIS OF TUBERCULOSIS


American researchers have invented a fully automated machine (Xpert MTB/RIF: rapid diagnosis of M. tuberculosis and rifampicin resistance), to identify the bacillus M. Tuberculosis in less than 2 hours. The process involves mixing the sputum with a product that inactivates the M tuberculosis, including the mixture in a plastic cartridge and its subsequent inclusion in a special container of the machine that runs the analysis of DNA by PCR (Polymerase Chain Reaction). Though not 100% accurate, the method permit to detect cases reported as negative or with scarce bacilli as those occurring in HIV-TB co-infection. The sensitivity and specificity of the test is: 98.2% and 99.2% respectively. The sensitivity to identify rifampin-resistant bacteria is 98.1%. This method is a prelude of future diagnosis (perhaps in less than 10 years), of diseases in which with only 1 ml of blood from the patient or a small piece of tissue will be done by molecular methods simultaneous diagnoses of thousands of diseases, in less than 5 minutes.


DIAGNOSTICO RAPIDO DE TUBERCULOSIS.


Investigadores americanos han inventado una maquina totalmente automatizada (Xpert MTB/RIF:diagnóstico rápido de M. tuberculosis y resistencia a la Rifampicina), para identificar al bacilo M. tuberculosis en menos de 2 hs. El proceso requiere mezclar el esputo con un producto que inactiva al M tuberculosis, incluir la mezcla en un cartucho de plástico y su posterior inserción en un recipiente especial de la maquina que ejecuta el análisis de DNA mediante PCR (Reacción en cadena de Polimerasa). Aunque no es 100%, preciso, el método permite detectar casos informados como negativos o con escasos bacilos como los que ocurren en la coinfección HIV-TBC. La sensibilidad y especificidad del método es 98,2% y 99,2%, respectivamente. La sensibilidad para identificar bacterias resistentes a Rifampicina es 98.1%. Este método es el preludio de diagnósticos futuristas (tal vez en menos de 10 años), de enfermedades en las que con solo 1 ml de sangre del paciente o una pequeña porción de tejido se harán mediante métodos moleculares los diagnósticos simultáneos de miles de enfermedades, en menos de 5 minutos.
