There are no published data on defaulting from DOTS in Benin City which necessitated this study to determine the rate of defaulting and identify factors that significantly contribute to defaulting in Benin City, Nigeria. Methods: This was a case control study from August to December 2011 of 1253 TB patients placed on DOTS in Benin City. The two DOTS centres used for the study were situated in University of Benin Teaching Hospital (UBTH) and Egor local government secretariat, both in Egor local government area (LGA) in Benin City. Out of 1253 patients registered on DOTS in the two study centres, 722 patients comprising of 172 defaulters and 550 non- defaulters were selected for the study using the inclusion and exclusion criteria. Logistic regression analysis was performed to determine association between independent variables and defaulting. Results: The default rate was 23.8%. Defaulting was significantly associated with: male sex (OR 3.05;95%CI 1.60 - 5.80), being married (OR 3.06;95%CI 1.34 - 6.99), a history of travel (OR 6.87;95%CI 3.19 - 14.80) and concomitant drug use with TB drugs (OR 1.95;95%CI 1.02 - 3.73). Conclusion: The default rate from DOTS in Benin City and the factors significantly associated with defaulting have given us some information initially unavailable about defaulting from DOTS in Benin City. TB control programmes taking these factors into consideration need to be done to promote compliance to treatment.展开更多

However, the cut-off point for clinical TB and Mtb infection is not well established in TB endemic countries of sub-Saharan Africa. In this study we compared the size of TST induration in smear positive pulmonary TB (PTB) patients, their house-hold contacts and community controls in high endemic setting in Ethiopia. Methods: In a health facility-based cross-sectional study, smear positive PTB patients were recruited. Their household contacts traced, and community controls were recruited from neighbourhoods. Sputum sample collected from patients were examined using smear microscopy. Participants were also tested by TST and QuantiFERON? -TB Gold In–Tube test (QFTGIT). Results: From a total of 224 study participants, skin test induration data were available for 48 PTB patients, 88 household contacts and 75 community controls. All 48 patients, 64 (72.2%) of the household contacts and 35 (46.7%) of the community controls had skin test induration ≥ 10 mm. Moreover, 44 (91.7%) PTB patients, 58 (65.9%) of the household contacts and 26 (34.7%) of the community controls had skin test induration ≥ 15 mm, respectively. The mean size of TST induration was significantly higher in TB patients (18.1mm) compared to that of household contacts (13.6 mm) and community controls (7.9 mm) (pMtb展开更多
