Xpert MTB/Rif assay app licati on for molecular diagnosti cs of TB in HIV-patie nts
Abstract
We used Xpert MTB/Rif assay for express detection of Mycobacterium tuberculosis (MTB) and performed the drug susceptibility testing for rifampicin in patients with HIV/TB coinfection. We investigated 294 samples (189 respiratory samples such as sputum, bronchial secret, bronchial lavage and 105 extrapulmonary samples such as cerebrospinal liquid, faeces, tissue, lymph node etc.), obtained from 106 HIV/TB patients, admitted at the Clinic № 2 of The Moscow research and clinical center for TB control. Xpert MTB/Rif assay application for molecular diagnostics in HIV/TB-patients increased of detection frequency of MTB to 21,7% in respiratory samples and to 14% in extrapulmonary samples Multidrug resistant MTB were detected most frequently then monoresistant and susceptible to the main antituberculosis drugs MTB strains in all types of samples obtained from HIV/TB patients
