Session TitleTuberculosis PostersSESSION TYPE: Poster PresentationsPRESENTED ON: Saturday, March 22, 2014 at 01:15 PM - 02:15 PMPURPOSE: Multidrug resistant tuberculosis (MDR-TB) and extensively drug-resistant (XDR-TB) is a major public health threat in China. To investigate risk factors for poor treatment outcomes in patients with MDR-TB and XDR-TB in China.MethodsWe retrospectively analyzed TB Patients with culture-proven MDR-TB and HIV-negative from July 2006 to June 2010 in five large-scale Tuberculosis Specialized Hospitals in China.ResultsA total of 586 HIV-negative patients with MDR-TB were included in the final analysis. Among them, 169 cases (28.8%) had XDR-TB. The patients were divided into XDR-TB group (n=169) and other MDR-TB group (MDR-TB excluding XDR-TB) (n=417). In total, 240 patients (40.95%) had treatment Success, and 346 (59.05%) had Poor treatment outcomes. The treatment success rate in other MDR-TB group was 52.2%, significantly higher than that in XDR-TB group (13%, P<0.001), whereas poor treatment outcomes were more common in patients with XDR-TB than in patients with other MDR-TB (87 vs.47.8%; P<0.001). In multivariate logistic regression analysis, Poor Treatment Outcomes were associated with duration of previous anti-TB treatment of more than one year, a BMI less than 18.5 kg/m2, XDR, retreatment, diabetes, tumor, decreased albumin, cavitation and 5~6 lung fields with disease. In multivariate logistic regression analysis, having a tumor was the only independent risk factor associated with death.ConclusionsThe prevalence of MDR- and XDR-TB is high in some areas in China with poor treatment outcome. The presence of XDR, low BMI, hypoalbuminemia, comorbidity and previous anti-TB treatment are independent poor prognostic factors in patients with MDR-TB. Effective TB control strategies should be implemented to prevent the development and spread of MDR- and XDR-TB in China.Clinical ImplicationsThis study clarified the risk factors associated with poor treatment outcome among patients with MDR- and XDR-TB, which provides imprtant evidence to treat the patients with MDR- and XDR-TB better.DisclosureThe following authors have nothing to disclose: Shenjie Tang, Shouyong Tan, Lan Yao, Fujian Li, Li Li, Zhixin Guo, Yidian Liu, Xiaohui Hao, Yanqiong Li, Xiuxiu Ding, Zhanjun Zhang, Li Tong, Jianan HuangNo Product/Research Disclosure Information.
