Abstract 27 — Prevalence and Management Approach of Latent Tuberculosis Infection in Rheumatology Patients

Journal of Clinical Rheumatology and Immunology, 2023
Prior to immunosuppression, rheumatology patients are routinely screened for latent tuberculosis infection (LTBI) using Interferon-Gamma Release Assays (IGRA).

Concordance between tuberculin skin test and interferon-gamma release assay for latent tuberculosis screening in inflammatory bowel disease [PDF]

Intestinal Research, 2020
Background/Aims Latent tuberculosis screening is mandatory prior to initiating anti-tumor necrosis factor (anti-TNF) medications. Guidelines recommend interferon-gamma release assays (IGRA) as first line screening method for the general population ...

Comparing the cost-effectiveness of two screening strategies for latent tuberculosis infection in Portugal

Pulmonology, 2021
Introduction and objectives Screening for latent tuberculosis infection (LTBI) in close contacts of infectious TB cases might include Tuberculin Skin Test (TST) and Interferon-Gamma Release Assays (IGRA), in combination or as single-tests.

Predictors of interferon-gamma release assay results and their association with COVID-19 infection outcomes

IJTLD Open
BACKGROUND: An ‘indeterminate’ interferon-gamma release assay (IGRA) result used in the diagnosis of latent TB infection (LTBI) is most commonly due to an inadequate control (or ‘mitogen’) response, which may reflect underlying T-cell dysfunction ...

SERS Facemask for Rapid and Portable Sensing Mycobacterium Tuberculosis Antigens for TB Screening

Advanced Science, EarlyView.
Our study introduced an Au─Ag embedded covalent organic framework (U@COF) ‐mediated facemask for sensing TB antigen ESAT‐6/CFP‐10 complex in clinical droplet samples toward TB screening. Practical analysis of clinical samples demonstrated the availability of our facemask, which is capable of identifying the TB subjects (N = 17) from healthy candidates (

Interferon-gamma release assay versus tuberculin skin test for latent tuberculosis infection among HIV patients in Brazil

Brazilian Journal of Infectious Diseases, 2016
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 ...

Investigation of Specific IgG‐Secreting Cells in Congenital Toxoplasmosis: The TOXODIAG Study

Journal of Clinical Laboratory Analysis, EarlyView.
This study addressed the difficulty of establishing a postnatal biological diagnosis of congenital toxoplasmosis, particularly in the absence of toxoplasmosis monitoring during pregnancy, as is the case in many countries. Our work presents an ELISPOT (Enzyme‐Linked Immunospot) method adapted for the detection of B lymphocytes primed to produce IgG ...

The association between type 2 diabetes and pulmonary cavitation revealed among IGRA-positive tuberculosis patients

Frontiers in Medicine, 2023
The co-occurrence of tuberculosis (TB) and diabetes mellitus (DM) presents a significant obstacle to TB eradication. Pulmonary cavitation can occur in severe cases of TB, particularly in patients with DM.
