13. Serial QuantiFERON-TB Gold In-Tube assay and tuberculin skin test to diagnose latent tuberculosis in household Mexican contacts: conversion and reversion rates and associated factors using conventional and borderline zone definitions
A cohort of 123 adult contacts was followed for 18‐24 months (86 completed the follow-up) to compare conversion and reversion rates based on two serial measures of QuantiFERON (QFT) and tuberculin skin test (TST) (PPD from TUBERSOL, Aventis Pasteur, Canada) for diagnosing latent tuberculosis (TB) in household contacts of TB patients using conventional (C)

14. Tuberculin skin test and interferon-gamma release assay values are associated with antimicrobial peptides expression in polymorphonuclear cells during latent tuberculous infection
It has been reported that patients with progressive tuberculosis (TB) express abundant amounts of the antimicrobial peptides (AMPs) cathelicidin (LL-37) and human neutrophil peptide-1 (HNP-1) in circulating cells, whereas latent TB infected donors showed no differences when compared with purified protein derivative (PPD) and QuantiFERON®-TB Gold (QFT)-healt

15. Osteoarticular tuberculosis in an HIV-positive patient: a case report
The authors report a case of a 38-year-old HIV-positive woman, with subcutaneous nodules on the thoracic region with 3 months of evolution. Clinical, laboratory, and epidemiological features were evaluated and associated with apparent damage to the T11-T12 vertebrae, identification by imaging tests, positivity in a polymerase chain reaction-based test, and r

16. Prevalence of latent tuberculosis and treatment adherence among patients with chronic kidney disease in Campo Grande, State of Mato Grosso do Sul
Introduction The primary strategy for tuberculosis control involves identifying individuals with latent tuberculosis. This study aimed to estimate the prevalence of latent tuberculosis in chronic kidney disease (CKD) patients who were undergoing hemodialysis in Campo Grande, State of Mato Grosso do Sul, Brazil, to characterize the sociodemographic and clini

17. The use of Mycobacterium tuberculosis HspX and GlcB proteins to identify latent tuberculosis in rheumatoid arthritis patients
Rheumatoid arthritis (RA) is an autoimmune disease characterised by the destruction of articular cartilage and bone damage. The chronic treatment of RA patients causes a higher susceptibility to infectious diseases such as tuberculosis (TB); one-third of the world’s population is latently infected (LTBI) with Mycobacterium tuberculosis(Mtb). The tuberculin

18. Tuberculin skin testing in inflammatory bowel disease patients from an endemic area of Brazil
Objective: Inflammatory bowel disease (IBD) is a chronic disorder involving the gastrointestinal tract. Immunosuppressive drugs are usually prescribed to treat IBD patients, and this treatment can lead to tuberculosis reactivation. This paper aimed to analyze tuberculin skin test (TST) results in IBD patients at a reference center in Brazil. Methods: We e

20. Genetic polymorphism and immune response to tuberculosis in indigenous populations: a brief review
We systematically reviewed studies of the immune response to tuberculosis and the genetic polymorphisms associated with Th1-or Th2-mediated cytokine expression in indigenous populations. A bibliographic search was performed on the Medline and ISI databases and included studies published between January 1980 and October 2011. The search terms were tuberculosi

21. Teste tuberculínico: comparação de dois instrumentos de leitura / Tuberculin skin test: comparison of two reading instruments [Thesis]. São Paulo: School of Public Health of USP, 2012.
Introduction- The active search of individuals infected with Mycobacterium tuberculosis aims to prevent the development of infection to the disease tuberculosis and ancillary knowledge of new cases of the disease. The tuberculin test is an important tool to identify individuals (infected) and non-reactors reactors (noninfected). It can be applied from variou

22. InfecÃÃo latente por mycobacterium tuberculosis em portadores de infecÃÃo por HIV/AIDS: anÃlise atravÃs do uso de teste tuberculÃnico e teste de liberaÃÃo de interferon-gama / Latent infection by mycobacterium tuberculosis in patients with HIV / AIDS: analysis through the use of tuberculin test and interferon-gamma release
People living with HIV have an enhanced chance to develop and to die of tuberculosis (TB). Many studies demonstrate that chemoprophylaxis for latent tuberculosis infection (LTBI) reduces the progression to active TB. Indeed, the diagnosis of LTBI is controversial. In Brazil, the only test approved for use is the tuberculin skin test (TST), however, this test

23. Estudo sobre contatos de pacientes com tuberculose pulmonar na região metropolitana de Goiânia
Tuberculosis (TB) affects millions of people every year and it is estimated that one third of world‟s population is infected with Mycobacterium tuberculosis (Mtb). The identification of infection and monitoring of close contacts of TB patients would contribute to disease dissemination control. In the present study the epidemiological characteristics th

24. Tuberculin skin testing in HIV-infected patients in Campo Grande, Mato Grosso do Sul State, Brazil
A cross-sectional study on HIV/AIDS was carried out in 108 outpatients from the university hospital of the Federal University of Mato Grosso do Sul, Campo Grande, Brazil, from July to December 2008, to investigate latent tuberculosis infection using the tuberculin skin test (TST). The prevalence of positive results was 13.9%. The CD4+ T cell count (p = 0.091
