Quantiferon-TB Gold in the Assessment of Latent TB in Patients Candidate to Treatment or Treated With TNFα Antagonists

The purpose of this study is to evaluate the value of Quantiferon-TB Gold (QFT-G) assay in the screening for latent tuberculosis infection (LTBI) in rheumatologic patients due to start or on treatment with TNFα antagonists. The results of QFT-G will be compared to tuberculin skin testing (TST) and correlated to clinical and demographic data. The study hypothesis is that the inclusion of QTF-G in the screening strategy will allow a more accurate assessment of LTBI infection.

Quantiferon for Detection of Latent Tuberculosis in Healthcare Workers

The accuracy of tuberculin skin test (TST) for detecting latent tuberculosis is limited in countries with a high proportion of population having received vaccination with the BCG. We aim to determine the cost-effectiveness of Quantiferon gold (QTFG), compared to BCG vaccine to detect latent tuberculosis in exposed healthcare workers (HCWs)

Screening for Latent Tuberculosis in Healthcare Workers With Quantiferon-Gold Assay: A Cost-Effectiveness Analysis

The ministry of health in Israel requires all health-care workers to undergo screening for latent Tuberculosis infection (LTBI) prior to starting work. This is based on the Mantoux skin test, which is notoriously unreliable. In recent years, more specific and sensitive tests based on interferon-gamma secretion to TB antigens have come to market, and most current evidence shows that many mantoux positive persons do not have LTBI. Quantiferon-GOLD is one of these assays. ...

T Cell Interferon-Gamma Release Assay (TIGRA) in Immunocompromised Individuals

Until recently, the tuberculin skin test (TST) was the only available diagnostic assay for detection of latent infection with M. tuberculosis (LTBI). Despite the low overall incidence of symptomatic tuberculosis infection in low-prevalence countries, the potential mortality and morbidity mandate constant vigilance to identify patients at risk for reactivation. Due to systemic immunosuppression, immunocompromised patients with latent M. tuberculosis infection are at increased ri...

Evaluation of the QuantiFERON-TB Test.

To compare the results of the investigational test to the currently approved QuantiFERON-TB Gold In-Tube test.

Evaluation of the QuantiFERON-TB Test.

To compare the results of the investigational test to the currently approved QuantiFERON-TB Gold In-Tube test.

Evaluation of the 4th Generation QuantiFERON-TB Test (QFT-Plus) for the Detection of Tuberculosis Infection

To compare the positivity rate of the investigational assay to the currently approved QuantiFERON-TB Gold In-Tube assay.

Epidemiological Study In Tuberculosis-Endemic Urban Area in Senegal

A cross-sectional childhood M. tuberculosis infection survey of age-specific rates (defined by positivity to the test QuantiFERON-TB Gold Plus) will be conducted in Senegal to collect information on the local TB endemic to inform site selection, sample size, and recruitment strategies for a future efficacy trial of vaccine candidate MTBVAC in young children.

QuantiFERON Change During Anti-tuberculosis Medication

The aim of this study is to evaluate the change of QuantiFERON-TB gold in tube assay (QFT) during the treatment of active tuberculosis.


Comparison of the Tuberculin Skin Test (TST) and QuantiFERON ®-TB Gold Test (QFT-G) In Patients With Rheumatoid Arthritis Being Considered for Anti-TNF-Alpha Therapy

This research will help doctors interested in the usefulness of a new test to discover hidden tuberculosis infections in patients diagnosed with rheumatoid arthritis (RA). This new test is called Quantiferon-Gold (QFT-G). After immune system medicines that block TNF-alpha (a protein manufactured by white blood cells to stimulate and activate the immune system in response to infection or cancer) started to be used, the rate of tuberculosis infections in patients treated with ...

Package of Care to Improve Retention in ART and Mortality Among Treatment Naive HIV Infected Individuals

This is a cluster randomized trial to determine whether a package of care including rapid antiretroviral therapy (ART) initiation, as compared to standard ART initiation, improves mortality, retention in care and viral suppression among treatment naive people living with HIV (PLHIV) in Nepal. Package of care includes immediate screening and treatment of opportunistic infections (OIs), rapid ART initiation and enhanced retention in care using mobile health (mHealth) and weekly/b...

The Clinical Utility of QuantiFERON in the Diagnosis of Active Tuberculosis

The investigators will evaluate the usefulness of QuantiFERON-TB Gold in-tube (QFT) in the diagnosis of active tuberculosis in young adults group, highly clinically suspected tuberculosis.

Evaluation of 2 Interferon γ Assays in the Diagnosis of Latent Tuberculosis in HIV-Infected Patients.ANRS EP 40 QUANTI SPOT

The aim of this study is to estimate the usefulness of QuantiFERON TB Gold In-Tube® and T-SPOT.TB® for the diagnosis of latent tuberculosis in HIV infected antiretroviral naive patients: 80 originated from low TB prevalence countries, without any active TB; 80 HIV infected antiretroviral naïve patients originated from high TB prevalence countries, without any active TB, 40 HIV infected patients with active TB and 40 HIV negative patients with active TB.

Chronic Urinary Retention in Elderly Living in Homes for the Aged : Benefits of Bladder Scan Screening

The goal of this cross-sectional, multicentric and descriptive epidemiological study is to assess the prevalence of chronic urinary retention (CUR) in elderly living in residential care for dependent elderly people in order to determine if there is an interest in offering them a bladder scan screening.

Charlotte Retention in Care Study

The objective of the Charlotte Retention in Care study is to assess if clinical decision support systems (CDSS) that produce standardized alerts for measures of retention in care across clinics in the city of Charlotte, North Carolina have the ability to increase retention in care measures within clinics and in surveillance reports.

Parent Education and Choice About Newborn Screening and Bloodspot Retention

To address the content, timing, efficacy, and impact of prenatal education about newborn screening generally and sample retention specifically.

Is Tuberculin Skin Testing Effective in Screening for Latent TB in Elderly Residents of Nursing Homes?

In face of the increased rates of tuberculosis in residents of long term care facilities, annual screening for latent tuberculosis is recommended. Tuberculin skin testing using purified protein derivative (PPD) is used for this purpose. Sensitivity of the PPD testing is, however, dependent on a normal T cell function. It is now evident that the immune system undergoes age-associated alteration known as immune senescence. The depressed T-cell responses may clinically manifest as...

Clinical Evaluation of the QuantiFERON CMV Assay

Validate the use of the device in the clinical setting for assessing the risk of CMV Infection in SOT recipients after the completion of antiviral prophylaxis.

Clinical Evaluation of Quantiferon-Monitor to Predict Outcomes in Solid Organ Transplant Recipients

The study will prospectively determine the clinical utility of non-pathogen specific cellular immunity assessment using the Quantiferon-Monitor to quantify the degree of immunosuppression. The investigators will use the results of the assay to predict whether patients develop opportunistic infections and predict organ rejection.

Patient Retention in HIV Medical Care in a Primary Care Practice in Australia

The purpose of this study is to determine linkage and retention in care in patients with HIV infection and reasons for loss to follow up Care in a High HIV-caseload Inner City Primary Care Practice in Sydney, Australia. The investigators hypothesise that patients attending HHMP will have higher rates of linkage and retention in care than the US HIV-infected population, and equivalent to Australian modelling.

Randomized controlled study that will evaluate the effect of a text message-based strategy to improve retention in HIV care.

Use TST and QFT-RD1 Test to Monitor the Tuberculous Infection in Patients, Close Contact People and Health Care Workers

Tuberculosis is still the most common infectious disease in Taiwan. The infants in Taiwan have been vaccinated at birth with BCG -Tokyo 171 strain since 1951. The BCG vaccination rate is 97% among first grade students in a recent national survey. Even with such a high BCG vaccination coverage, Taiwan still has a relatively high TB incidence rate. In 2004, there were totally 16,784 newly diagnosed TB cases and the annual incidence was 74.11 per 100,000 population nationally. Nea...
