Dosagem da atividade da adenosina deaminase no líquido pleural para o diagnóstico da tuberculose pleural

Abstract: INTRODUÇÃO: O diagnóstico da tuberculose pleural permanece um desafio, pois a sensibilidade dos testes tradicionais é baixa. O exame histopatológico da pleura é o método mais preciso, com até 80% de sensibilidade. A dosagem da adenosina deaminase foi introduzida mais recentemente, mas sua utilidade no diagnóstico da tuberculose pleural no Brasil não foi suficientemente esclarecida. OBJETIVO: Verificar a sensibilidade e a especificidade de um método experimental de dosagem da atividade da adenosina deaminase em… Show more

“…With these cut-off levels, the concordance between the methods was found to be 96.8% (simple concordance test), which is in accordance with the findings of other authors. (23) In the literature, the cut-off value recommended for the diagnosis of TB in CSF samples is 9 U/L. We considered this value for the two methods, since, using this value, concordance was found to be 100% (simple concordance test), although the mean percentage of the differences between the results obtained by the two methods was approximately 35%.…”

“…En relación a la prueba de ADA como diagnóstica de tuberculosis pleural, diversos autores han encontrado diferentes puntos de corte, que varían desde 30 hasta 100 UI/L (tabla 2) (7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24) , dependiendo esto del grupo de pacientes que formaron parte del estudio, la población cuya epidemiología del Mycobacterium es distinta y los criterios tomados en cuenta para el diagnóstico definitivo de las diferentes enfermedades que ocasionaron el derraTabla 2. Estudios realizados a lo largo del tiempo sobre el valor de la prueba de ADA y sus principales parámetros.…”
