    ABSTRACT: To determine the length of delay in initial health-seeking in new pulmonary tuberculosis (PTB) cases among migrant population in the eastern part of China, and factors associated with it. A cross-sectional study was conducted using a structured questionnaire in six counties in Shanghai, Guangdong and Jiangsu from May to October, 2008, to estimate the extent and factors responsible for delayed initial health-seeking of the new PTB cases. The interval between self-reported onset of TB symptoms and date of first attendance at any medical institution was determined. More than the median duration was defined as delayed health-seeking. A total of 323 new migrant PTB patients participated in the study. Only 6.5% had medical insurance. The median and mean durations to initial health-seeking were respectively 10 and 31 days. There was no significant association between socio-demographic factors and delayed initial health-seeking. Average monthly working days >24 (AOR, 1.61; 95% CI, 1.03-2.51), and hemoptysis or bloody sputum (AOR, 0.48; 95% CI, 0.28-0.85) were significantly associated with delayed initial health-seeking. Interventions to improve health seeking behavior among the migrant population in China must focus on strengthening their labor, medical security and health education.

    ABSTRACT: The objectives of this study were to evaluate the suitability of the TB-SA antibody test to diagnose tuberculosis in sputum smear negative (SS-) pulmonary tuberculosis (TB) patients and its applicability for monitoring treatment outcomes in these patients. This study was conducted in three counties/districts in Chongqing Municipality, Liaoning Province, China between June 2005 and June 2007. A total of 432 SS suspected pulmonary TB patients were recruited and their blood was collected prior to treatment, at the end of 1 month of treatment, 2 months of treatment and 6 months of treatment (E6MT). The serum samples were analyzed with a TB-SA antibody test kit. Of the 432 SS suspected pulmonary TB patients, serum samples were obtained at all time points in 316 patients and analyzed. The 316 patients were divided into three groups according to sputum smear and sputum culture results and the chest X-ray results before treatment and at E6MT. Ten point four percent were SS-/culture positive (C+), 73.1% were SS-/culture negative (C-) with X-rays abnormalities, and 16.5% were SS-/C- without X-rays abnormalities. The positive rates for TB-SA antibody in the three groups were 57.6, 44.6 and 44.2%, respectively, before treatment, and 18.2, 19.1 and 26.9%, respectively, at E6MT. There was a significant decrease in TB-SA antibody positivity with treatment for all 3 groups. The TB-SA antibody test may be a useful adjunct to diagnose tuberculosis in SS- pulmonary TB patients, and may be useful for monitoring treatment outcomes of SS- pulmonary TB patients.

    ABSTRACT: China has more and more floating population because of reform and opening-up. As one of the high burden countries in tuberculosis (TB) control in the world, China has to face more challenges about the TB case detection and treatment among floating population in China. Aim to evaluate the effect of case detection and treatment of the Floating Population TB Control Pilot Project from Global Fund Round Five (GFR5) TB Control Program in China. During October 2006 to September 2008, the pilot project was implemented gradually in 60 counties in Tianjin, Shanghai, Jiangsu, Zhejiang, Fujian, Shandong and Guangdong. All quarterly reports of the pilot project were collected, and these materials were summarized and analyzed. In seven coastal provinces, 19,584 active pulmonary TB (PTB) cases were registered among floating population in 2 years. Among the active PTB cases, 87.2% were 15-45 years old, and 62.8% were male. In second year, 15,629 active PTB cases were registered, and the overall registration rate was 68 per 100,000 people. DOT treatments were provided for 18,125 active PTB cases in 2 years, and overall DOT treatment rate was 92.6%. There were 3,955 active PTB cases registered in first year, and the overall cure rate was 86.0%. Through the implementation of the pilot project, the TB case detection and treatment among floating population have been enhanced in pilot areas of China. The useful experience and results from the pilot project have been being gradually generalized nationally.
