Abstract
INTRODUCTION:
Gene-Xpert MTB RIF (Xpert) is based on nucleic acid amplification by real-time polymerase chain reaction, which allows for the identification of Mycobacterium tuberculosis and rifampin resistance. We describe the use of Xpert for extrapulmonary tuberculosis (EPTB) in children and adolescents.
METHODS:
A case series of two reference centers in Rio de Janeiro from 2014-2019.
RESULTS:
The final diagnosis of EPTB was established in 11/36 (31%) patients, with five cases detectable by Xpert. For lymph node evaluation (9/11), diagnosis by Xpert occurred in 5/9 patients, all with caseous aspects.
CONCLUSIONS:
Xpert can facilitate the rapid diagnosis of lymph node tuberculosis.
