TUBERCULOSIS: China: MDR and XDR TB stats

February 24, 2011


A third of samples taken from a Chinese hospital specializing in tuberculosis (TB) care were found to be resistant to at least one first-line drug, while 11% were multidrug-resistant TB (MDR TB) and 2% were extensively drug-resistant TB (XDR TB), according to a study published yesterday.
Researchers studied 989 Mycobacterium tuberculosis samples (860 new cases and 129 retreated cases) from Shandong Provincial Chest Hospital, which is China's only provincial hospital specializing in TB. Median patient age was 40.
Of the isolates, 319 (32.3%) were resistant to at least one first-line drug, 107 (10.8%) were MDR TB, and 20 (2%) were XDR TB, or 10.8% of MDR TB cases. Recent surveillance data from Beijing and Shanghai found the proportion of XDR TB cases among MDR TB cases to be 6.3%.

The authors conclude, "XDR TB is of major concern in China."
