1. Cutaneous tuberculosis: epidemiological, clinical, diagnostic and therapeutic update
Abstract Tuberculosis is certainly one of the diseases considered to be ancient on planet Earth. The etiological agent of tuberculosis is Mycobacterium tuberculosis. This terrible bacterial infection still results in severe socioeconomic consequences to date, and its complete eradication represents a great challenge. It constitutes one of the most important

2. Characteristic profile of antibody responses to PPD, ESAT-6, and CFP-10 of Mycobacterium tuberculosis in pulmonary tuberculosis suspected cases in Surabaya, Indonesia
Abstract Accurate and rapid diagnostic tools are important aspects of managing tuberculosis (TB) cases appropriately. However, the sensitivity and specificity of diagnostic kits based on immune response such as the tuberculin skin test (TST) and interferon gamma release assay (IGRA) are still debated. Thus, the exploration and assessment of specific biomarke

4. Esclerite posterior isolada associada à tuberculose
RESUMO A tuberculose (TB) ocular foi considerada rara, embora a sua incidência tenha variado significativamente ao longo do tempo e nas diferentes populações. A TB latente é diagnosticada quando alguém é infetado com Mycobacterium tuberculosis sem possuir doença ativa. Durante a última década, testes tendo por base interferon gamma release assay for

5. Clinical Study of Extrapulmonary Head and Neck Tuberculosis: A Single-Institute 10-year Experience
Introduction Although the incidence of tuberculosis (TB) in Japan has been decreasing yearly, Japan remains ranked as an intermediate-burden country for TB. Objective This study aims to investigate the current situation of head and neck extrapulmonary TB (EPTB) diagnosed in our department. Methods We retrospectively reviewed the clinical records of 47

6. Interferon-gamma release assay versus tuberculin skin test for latent tuberculosis infection among HIV patients in Brazil
Abstract Setting Patients HIV+ attending in a reference clinic, Southern Brazil. Objective To compare the interferon-gamma-release assay (IGRA – QuantiFERON® TB Gold In-Tube) with the tuberculin skin test (TST – PPD-Rt 23) for latent tuberculosis infection (LTBI) in patients with HIV. Design Cohort study. Patients were simultaneously submitted to the

7. Diagnosis of latent Mycobacterium tuberculosis infection: tuberculin test versus interferon-gamma release
Abstract: INTRODUCTION: The treatment of individuals with active tuberculosis (TB) and the identification and treatment of latent tuberculosis infection (LTBI) contacts are the two most important strategies for the control of TB. The objective of this study was compare the performance of tuberculin skin testing (TST) with QuantiFERON-TB Gold In TUBE(r) in

8. 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

9. 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

10. Determinação da sensibilidade e especificidade de teste de liberação de interferon-gama por linfócitos ativos estimulados por antígenos específicos do Mycobacterium tuberculosis em crianças / Evaluation of the sensibility and the specificity of an interferon-gamma release assay after lymphocyte stimulation by specific Mycobacterium tuberculosis antigens in children
INTRODUÇÃO: A tuberculose é um problema grave de saúde pública, acometendo indivíduos em todas as faixas etárias e em todos os estratos socioeconômicos. Apesar de estarem sob grande risco de adoecimento, as crianças carecem de meios diagnósticos sensíveis e específicos. Neste estudo avaliou-se em crianças a acurácia de um teste baseado na dosag

11. Immunomodulatory action of propolis on macrophage activation
Propolis has been the subject of several recent studies, with the aim of elucidating its biological and pharmacological properties. Propolis has a well-known antimicrobial activity as well as antioxidant, antitumoral, antiinflammatory, and regenerative properties, but literature about its effects on the immune response is scarce. The goal of this work was to

12. Human gamma interferon production by cytotoxic T lymphocytes sensitized during hepatitis A virus infection.
The production of interferon (IFN) during a chromium-51 release assay with hepatitis A virus (HAV)-infected fibroblasts and autologous peripheral blood lymphocytes from patients with acute HAV infection was studied to determine whether IFN plays a role in immunopathogenesis of hepatitis A infection in humans. Skin fibroblasts of eight patients after acute HA
