BACKGROUND Migration is one of the major causes of tuberculosis in developed countries. Undocumented patients are usually not screened at the border and are not covered by a health insurance increasing their risk of developing the disease unnoticed. Urban health centres could help identify this population at risk. The objective of this study is to assess the prevalence of latent tuberculosis in...

BACKGROUND: Currently in the U.S. it is recommended that tuberculosis screening and treatment programs be targeted at high-risk populations. While a strategy of targeted testing and treatment of persons most likely to develop tuberculosis is attractive, it is uncertain how best to accomplish this goal. In this study we seek to identify geographical areas where on-going tuberculosis transmission...

The aim of the present study was to perform cost-minimisation analysis of contact investigation from a public health perspective using the tuberculin skin test (TST) and a new blood assay, QuantiFERON-TB Gold (QFT-G). A decision-analysis model simulated the costs of investigating a cohort of adult close tuberculosis contacts by the public health service following the current German guidelines o...

ObjectiveTo explore whether all individuals with diabetes are at an increased risk of tuberculosis or there high-risk groups patients.MethodsA population-based census was conducted in China, including 27 807 individuals. Risk factors for incident were investigated and participants included the study linked to Tuberculosis Management Information System. Cox proportional hazards models adjusting ...

BACKGROUND Tuberculosis prevalence is generally low in industrialized countries, but many cities now operate surveillance programmes to actively screen for tuberculosis in known risk groups including homeless people. While several studies have reported on individual screening programmes, this study is the first known systematic review specifically looking at chest x-ray screening programmes for...

Switzerland (6). Failure to complete a full course of treatment may lead to relapse and emergence of resistant strains. A growing proportion of cases of tuberculosis observed in Europe is in migrants, some undocumented, from the developing world (3). Strong political measures should be enforced to ensure access to healthcare services with respect to confidentiality (as recently stated in the Ne...

Tuberculosis control depends on successful case finding and treatment of individuals infected with Mycobacterium tuberculosis. Passive case finding is widely practised: the present study aims to ascertain the consensus and possible improvements in active case finding across Europe. Recommendations from national guidelines were collected from 50 countries of the World Health Organization Europea...

OBJECTIVE To measure agreement between nine structured approaches for diagnosing childhood tuberculosis; to quantify differences in the number of tuberculosis cases diagnosed with the different approaches, and to determine the distribution of cases in different categories of diagnostic certainty. METHODS We investigated 1445 children aged < 2 years during a vaccine trial (2001-2006) in a rura...

The ongoing selection of multidrug-resistant strains of Mycobacterium tuberculosis has markedly reduced the effectiveness of the standard treatment regimens. Thus, there is an urgent need for new drugs that are potent inhibitors of M. tuberculosis, that exhibit favorable resistance profiles, and that are well tolerated by patients. One promising drug target for treatment of mycobacterial infect...

Current guidelines advocate screening hemodialysis patients for latent tuberculosis infection; however, the tuberculin skin test (TST) is believed to be insensitive in this population. This study compared the diagnostic utility of the TST with that of an IFN-gamma assay (T-SPOT.TB) and the clinical consensus of an expert physician panel. A total of 203 patients with ESRD were evaluated for late...
