Nafiye Urganci, Derya Kalyoncu
BACKGROUND: The aim of the study was to determine tuberculin skin test reactivity and associated factors in pediatric patients with celiac disease (CD). METHODS: Tuberculin skin test (TST) was performed on 28 patients with CD aged from 1 year to 15 years (mean, 6.64±4.8) and 28 healthy age and sex-matched children. The association between TST reactivity and parameters such as age, gender, malnutrition, clinical presentation, compliance to gluten free diet and response to hepatitis A and B vaccinations were determined...

This report describes how Mycobacterium bovis infection was controlled and eventually eradicated in a farmed red deer herd in the north of England, following sustained tuberculin skin testing supplemented with serological (antibody) tests over a period of approximately two years. By taking advantage of the anamnestic antibody response produced by the skin test to detect skin test-negative, antibody-positive infected individuals, a total of 35 additional animals were identified, including 2 with gross visible lesions typical of bovine tuberculosis (BTB)...

BACKGROUND AND AIM: To conduct meta-analyses of all published studies on various aspects of association between vitamin D and tuberculosis (TB). METHODS: PubMed and Web of Knowledge were searched for all properly controlled studies on vitamin D and TB. Pooled odds ratio, mean difference or standardized mean difference, and its corresponding 95% confidence interval were calculated with the Cochrane Review Manager 5.3. RESULTS: A significantly lower vitamin D level was found in TB patients vs controls; vitamin D deficiency (VDD) was associated with an increased risk of TB, although such an association was lacking in the African population and in the human immunodeficiency virus-infected African population...

BACKGROUND: Bacille Calmette-Guérin vaccination (BCG) is known to cause false positive tuberculin skin test (TST) results from cross-reactions to mycobacterial antigens. However, the duration of BCG influence on the TST is poorly characterized. The objective of the study was to assess the long-term effect of BCG vaccination on TST reactivity. METHODS: Data on TST reactivity were prospectively collected during 1935-47 as part of a clinical trial among American Indians / Alaskan Natives and retrospectively thereafter between 1948 and 1998...

Tuberculosis is a public health problem worldwide, including in the United States-particularly among immunocompromised patients and other high-risk groups. Tuberculosis manifests in active and latent forms. Active disease can occur as primary tuberculosis, developing shortly after infection, or postprimary tuberculosis, developing after a long period of latent infection. Primary tuberculosis occurs most commonly in children and immunocompromised patients, who present with lymphadenopathy, pulmonary consolidation, and pleural effusion...

The management of latent tuberculosis (LTBI) in children represents an important issue for paediatricians because of the disease burden, the lack of a gold standard for the diagnosis and the high annual risk of progression to active disease. Areas covered: A review of English language articles on LTBI in children, published between the 1(st) of January 2010 and the 1(st) of July 2016, was conducted using multiple keywords and standardized terminology in PubMed database. This review provides an updated overview of the available tests for LTBI diagnosis in children, management strategies and treatment options...

Paratuberculosis vaccination in cattle has been restricted due to its possible interference with the official diagnostic methods used in tuberculosis eradication programs. To overcome this drawback, new possibilities to detect Mycobacterium bovis infected cattle in paratuberculosis vaccinated animals were studied under experimental conditions. Three groups of 5 calves each were included in the experiment: one paratuberculosis vaccinated group, one paratuberculosis vaccinated and M. bovis infected group and one M...

A latent tuberculosis infection (LTBI) prevalence survey was conducted using tuberculin skin test (TST) and Quantiferon test (QFT) in 1218 healthcare workers (HCWs) in Medellín, Colombia. In order to improve the prevalence estimates, a latent class model was built using a Bayesian approach with informative priors on the sensitivity and specificity of the TST. The proportion of concordant results (TST+,QFT+) was 41% and the discordant results contributed 27%. The marginal estimate of the prevalence P(LTBI+) was 62·1% [95% credible interval (CrI) 53·0-68·2]...

REVIEW
Nancy D Marín, Luis F García
The establishment of a protective T-cell response against mycobacterial infections involves different co-stimulatory molecules and their respective ligands. Among these molecules the Tumor Necrosis Factor Receptor Super-family (TNFRSF) and the Tumor Necrosis Factor Super-family (TNFSF) are known to be important members. This review analyzes the evidence that CD30 and CD153 (CD30L), members of the TNFRSF and TNSF, play key roles in the T cell-dependent anti-mycobacterial immune response. Mice deficient in either CD30 or CD153, or treated with antibodies blocking the effects or CD30 and CD153, and infected with M...

In this study, a case with tubercular choroiditis showing severe macular edema and progression of choroidal lesions following initiation of antitubercular treatment is presented and the management of posterior uveitis associated with tuberculosis is evaluated. A 40-year-old female patient was admitted with decreased vision in her right eye and her fundoscopic examination revealed serpiginous choroiditis. It was learned from her medical history that she had taken antitubercular therapy 9 years ago. Mantoux tuberculin skin test showed an area of induration measuring 15 mm and a positive interferon-gamma release assay was documented...

OBJECTIVE/BACKGROUND: Bovine tuberculosis (BTb) is mainly a disease of cattle, although it continues to infect human populations across the world. Operation of a test and slaughter plan in Iran since 1981 has lowered the frequency of BTb from >5% to <0.14% at the national scale. In 2015, unusual uncontrollable epidemics of BTb were detected in two cattle farms in municipal suburbs of Qazvin and Isfahan. These farms had a tuberculin-test-certified record of BTb-free status for the past 5 consecutive years, with no new cattle registered with either of the two herds during this time period...

OBJECTIVE/BACKGROUND: The aims of this talk are to: (a) provide an overview of our method of collecting, quantifying, and sizing infectious aerosols of Mycobacterium tuberculosis; and (b) to review data indicating that cough aerosol cultures of M. tuberculosis are the best predictors of infection and incident disease among household contacts of persons with active tuberculosis (TB). New infection was defined as tuberculin skin test conversion. METHODS: We developed a cough aerosol sampling system by placing two Andersen cascade impactor viability samplers inside a cylinder into which patients cough via connector tubing...

Bovine tuberculosis (TB) is an important zoonotic disease that is caused by Mycobacterium bovis. Eradication efforts in developed countries have reduced the prevalence of this disease significantly. TB can be difficult to diagnose based only on the clinical signs; therefore, it is usually diagnosed in the field with the tuberculin skin test and diagnostic blood tests, including the lymphocyte proliferation assay, the interferon (IFN)-γ assay, and enzyme-linked immunosorbent assay. The aim of this study was to compare the tuberculin and IFN-γ tests...

AIMS AND OBJECTIVES: The WHO estimate that 8.8millions new cases of tuberculosis occurred in 2010, (between 8.5 and 9.2millions) linked to 1.45millions death cases. The load of children tuberculosis is estimated at 10-15 per cent of the total load. In 2014 more than one million children have developed the disease. The children just as adults are exposed to contract and develop the multi resistant forms of the tuberculosis, constituting a major issue for the disease control. The children less than 5years of age are the most exposed to present the most serious and more often deadly forms of the illness...

Bovine colostrum contains compounds, which provide passive immune protection from mother to newborn calves. Little is known about cytokine levels and their role in bovine colostrum. Moreover, the capacity of bovine colostrum cells to mount specific immune responses after natural exposure to bovine tuberculosis (bTB) antigens in dairy herds has not been studied, thus far. The purpose of this study was to identify biomarkers for bTB infection measurable in bovine colostrum. The present study reveals that isolated-immune colostrum cells can mount a specific immune response against bTB antigens, by measuring the novo IFN-γ release in cell culture...
