Background: The diagnosis of presumed latent tuberculosis (TB) infection (LTBI) is problematic in people living with HIV (PLWH) because of sub-optimal sensitivity and high indeterminate rates, especially in those with advanced immunosuppression. Better diagnostic tools for LTBI are needed in this sub-population.
Methods: We compared the sensitivity of VIDAS TB-IGRA, a fully automated RD1-specific new interferon-ϒ-release assay (IGRA), to QFT-Plus in 77 PLWH with active pulmonary TB who had varying CD4 counts.

This preliminary study compares VIDAS TB-IGRA (bioMérieux, Marcy-l'Etoile, France) with the established QuantiFERON-TB Gold Plus (QFT-Plus) (Qiagen, Hilden, Germany) to evaluate diagnostic performance for the diagnosis of individuals infected with complex (latent infection and disease). The study was multi-center and performed between 2 October 2019 and 4 February 2020. Participants were divided into tuberculosis (TB) disease, high-risk, and low-risk populations.

Aim This study aims to investigate the seroconversion of antibodies against SARS-CoV-2 infection in pregnant women during their first and third trimesters, specifically during the second wave of the COVID-19 pandemic. Methodology This is a longitudinal follow-up study of pregnant women during the second peak of the COVID-19 pandemic. Patients in their first trimester (six to 12 weeks) were tested for SARS-CoV-2 IgM and IgG levels, with a repeat test conducted in the third trimester (28-40 weeks) using the automated VIDAS® (bioMérieux SA, Marcy-l'Étoile, France) system.

Background: Because of the pathophysiological role of vitamin D in health, there is an increased interest to check the clinical status of this vitamin. Immunochemical assays are commonly employed to determine 25-hydroxyvitamin D (25 (OH) D) in clinical laboratories and its testing could be influenced by pre-analytic and analytic issues. The aim of this study was to compare the 25(OH)D results obtained from three commonly used immunoassays in pregnant women to check a possible discrepancy between tests.
