The Clinical Utility of Polymerase Chain Reaction for the Diagnosis of Pleural Tuberculosis

Abstract: For specimens such as pleural effusion, in which the bacillary load is very low, the clinical utility of PCR testing seems highly limited.

“…(23) Um estudo avaliando o rendimento da reação em cadeia da polimerase no líquido pleural de 111 pacientes (57 com TB pleural) mostrou sensibilidade de 17% e especificidade 98%. (24) Além disso, as técnicas de amplificação de seqüên-cias de ácidos nucléicos ainda não foram validadas para uso em amostras não respiratórias como o líquido pleural. Assim, embora a detecção do áci-do nucléico do M. tuberculosis no líquido pleural seja o suficiente para se estabelecer o diagnóstico de TB pleural, seu uso na rotina de investigação de derrames pleurais não se justifica no momento.…”

“…PCR has an accepted role in the detection of TB bacilli in pulmonary specimens (6). For other body fluids, such as pleural effusion and CSF, the sensitivity of PCR was almost uniformly poor (8,(15)(16)(17). Moreover, PCR has high false-positive results due to cross-contamination in high-volume clinical laboratories (3).…”
