Introduction: Tuberculosis (TB), as the most common cause of death from infectious disease in the world, is estimated to rank 10th in view of the global burden of disease. Due to the increasing prevalence of this disease and reduce the incidence of smear-positive pulmonary TB in the province, this study was designed to investigate the TB epidemiology and its affected factors in Hamadan province...
Background and purpose: Identifying the types of immune cells in patients with tuberculosis (TB) including single-core and multi-core is of great benefit in control and treatment of these patients. The aim of this research was to compare differential cell count in Bronchoalveolar lavage (BAL) samples in patients with and without TB. Materials and methods: In this descriptive-analytical...
Osaka City has the highest tuberculosis (TB) notification rates in Japan. In the period 1999-2003, the TB control programme was strengthened, and the Stop TB Strategy was implemented to reduce the number of notified cases. The objective of this study was to assess the effect of these control activities in Osaka City, including the implementation of directly observed treatment (DOT), by analysin...
BACKGROUND HIV infection reduces the likelihood that individuals with pulmonary tuberculosis are smear positive and that they have cavitatory disease. Antiretroviral therapy (ART) may shift the pattern of disease to be more similar to that of HIV negative patients. This would aid diagnosis--which often depends on sputum smears--but would also increase infectiousness. We assessed the effect of H...
The World Health Assembly set targets to detect by 2005 at least 70% of all new sputum smear-positive cases arising each year and to cure at least 85% of these cases. The national tuberculosis (TB) control programmes of 199 countries reported that in 2005, 2.3 million new smear-positive cases were diagnosed under WHOs DOTS strategy, out of an estimated 3.9 million (95% confidence limit (CL) 3.4...
For 10 years the World Health Organisation has had a single answer to the deadly threat of tuberculosis (TB)— provide treatment to smear positive patients and watch them take it. In contrast with confident statements about how global TB would be brought under control when directly observed therapy, short course (DOTS) was introduced, TB continues to rise worldwide. The introduction of selected ...

The microscopic observation drug susceptibility assay (MODS) is a novel and promising test for the early diagnosis of tuberculosis (TB). We evaluated the MODS assay for the early diagnosis of TB in HIV-positive patients presenting to Pham Ngoc Thach Hospital for Tuberculosis and Lung Diseases in southern Vietnam. A total of 738 consecutive sputum samples collected from 307 HIV-positive individu...
BACKGROUND Excessive time between diagnosis and initiation of tuberculosis (TB) treatment contributes to ongoing TB transmission and should be minimized. In India, Revised National TB Control Programme (RNTCP) focuses on indicator start of treatment within 7 days of diagnosis for patients with sputum smear-positive PTB for monitoring DOTS implementation. OBJECTIVES To determine length of time...
BACKGROUND In Afghanistan, improving TB case detection remains challenging. In 2014, only half of the estimated incident TB cases were notified, and notifications have decreased since peaking in 2007. Active case finding has been increasingly considered to improve TB case notifications. While access to health services has improved in Afghanistan, it remains poor and many people seeking health s...
