Prevalence of extensively drug-resistant tuberculosis in Vladimir and Orel regions, Russia.
METHODS
Joint World Health Organization (WHO) projects in Vladimir and Orel regions, Russia.


OBJECTIVE
To study the prevalence of extensively drug-resistant (XDR) tuberculosis (TB).


METHODS
Drug susceptibility testing of second-line drugs (ofloxacin, kanamycin, capreomycin, ethionamide, cycloserine and para-aminosalicylic acid) was performed on isolates from multidrug-resistant TB cases from 1 January to 31 December 2006.


RESULTS
In Orel, 16 (21.3%) of 75 tested isolates were XDR-TB; in Vladimir, 9 (4.9%) of 182 isolates were XDR-TB. Bilateral lung involvement was significantly associated with XDR-TB (prevalence ratio = 2.61, 95%CI 1.01-6.72).


CONCLUSIONS
XDR-TB has emerged in Russia. It is crucial to prevent, diagnose and treat TB and MDR-TB more effectively.
