background: the risk of developing tuberculosis is high among chronic hemodialysis patients. the tuberculin skin test (tst) has been in use for diagnosing latent tb, but few data are available on tst in hemodialysis patients. objective: this study was done to identify the tst reactivity and frequency of booster effect in serial tst among hemodialysis patients. methods: a total of 100 patients i...

Tuberculin skin test (TST) interpretation can be confounded by Bacillus Calmette-Guerin (BCG) vaccination and infection with nontuberculosis mycobacteria (NTM). However, a wealth of epidemiologic information has allowed the formulation of recommendations for reasonably informed interpretation of the TST in most clinical situations. In the Middle East, the TST remains a useful test. BCG vaccinat...

Screening for active tuberculosis (TB) and latent TB infection (LTBI) is mandatory prior to the initiation of tumour necrosis factor-alpha inhibitor therapy. However, no agreement exists on the best strategy for detecting LTBI in this population. The aim of the present study was to analyse the performance of the tuberculin skin test (TST) and QuantiFERON-TB Gold in-tube (QFT-GIT) on LTBI detect...

BACKGROUND The tuberculin skin test (TST) is used to test for latent tuberculosis (TB) infection and support the diagnosis of active TB. However, little is known about the relationship between the TST result and the clinical presentation of TB disease. METHODS We analyzed US TB surveillance data, 1993-2010, and used multinomial logistic regression to calculate the association between TST resu...

PURPOSE End stage renal disease (ESRD) cases are associated with increased risk of tuberculosis. There is no gold standard method for detecting latent tuberculosis infection (LTBI) in ESRD. The aim of the present study was to analyze the performance of the tuberculin skin test (TST) and QuantiFERON-TB Gold in tube (QFT-G) in cases receiving hemodialysis (HD). METHODS The TST and QFT-G were pr...

BACKGROUND The tuberculin skin test (TST) is still the standard test for detecting latent infection by M tuberculosis (LTBI). Given that the Brazilian Health Ministry recommends that the treatment of latent tuberculosis (LTBI) should be guided by the TST results, the present study sets out to describe the coverage of administering the TST in people living with HIV at two referral health centers...

BACKGROUND Lithuania is a country with a high incidence of tuberculosis (TB), despite a high coverage with bacille Calmette-Guerin (BCG) vaccination. Until now the only method used to detect latent TB infection was the tuberculin skin test (TST). However, TST may have a cross reactivity to the BCG vaccine and to environmental mycobacteria. The aim of this study was to conduct assessments of the...

The use of testosterone supplementation therapy (TST) is increasing primarily in men with symptomatic hypogonadism. While TST has been shown to have numerous benefits, as its use increases, the role on cardiovascular health must be explored. Previous evidence showed no adverse cardiovascular risks associated with TST use; however, more recent studies suggest that there may be an associated risk...

BACKGROUND Tuberculosis is a major occupational hazard in low and middle-income countries. Limited data exist on serial testing of healthcare workers (HCWs) with interferon-γ release assays (IGRAs) for latent tuberculosis infection (LTBI), especially in low and middle-income countries. We sought to evaluate the rates of and risk factors for LTBI prevalence and LTBI test conversion among HCWs us...
