Abstract

SETTING: During 2000-2006, a regional anti-tuberculosis drug resistance surveillance study was conducted in Shanghai, China. OBJECTIVE: To determine the prevalence, trends and risk factors for drug-resistant tuberculosis (TB) in Shanghai, China. DESIGN: A retrospective study of all pulmonary TB patients reported in Shanghai during 2000-2006 was conducted. RESULTS: Of 8419 pulmonary TB patients, 16.6% had resistance to any first-line anti-tuberculosis drug and 4.0% had multidrug resistance (MDR). The percentage of TB patients with resistance to any first-line antituberculosis drug and MDR significantly increased during 2000-2003 (P = 0.01 and P < 0.01, respectively). After improvements in the TB control programme in 2004, the increasing trend in drug resistance was contained. Age 30-59 years, being an urban migrant and residence in an urban area of Shanghai were independently associated with resistance to any first-line drug and MDR in new cases, while age 30-59 years and being an urban migrant were independently associated with resistance to any first-line drug and MDR in previously treated cases. CONCLUSIONS: Drug-resistant TB and MDR-TB pose a challenge for TB control in Shanghai. Improved case management, including DOTS and appropriate treatment regimens, should be sustained to prevent further transmission and development of drug-resistant TB in this setting.
