Purpose: End stage renal disease (ESRD) cases are associated with increased risk of tuberculosis. There is no gold standard method for detecting latent tuberculosis infection (LTBI) in ESRD. The aim of the present study was to analyze the performance of the tuberculin skin test (TST) and QuantiFERON-TB Gold in tube (QFT-G) in cases receiving hemodialysis (HD).
Methods: The TST and QFT-G were prospectively performed in 96 ESRD cases undergoing HD. The agreement of the QFT-G and TST was assessed in two TST cut off values (10 mm and 5 mm) in Bacille Calmette Guèrin (BCG) vaccinated and non-vaccinated cases.
Results: Of 96 cases 67 were BCG vaccinated and 29 were BCG non-vaccinated. QFT-G was positive in 39.6% cases and indeterminate in 3.1%. TST was positive in 43.8% of cases in cut off value of 10 mm and positive in 58.3% of cases in cut off value of 5 mm. Agreement between TST and QFT-G results was fair in both BCG vaccinated and non-vaccinated cases in either cut off values, except in cut off value of 10 mm in BCG vaccinated cases in which the agreement was moderate.
Conclusion: The agreement between QFT-G and TST test is fair and there is no significant difference in both cut off values of TST in screening of LTBI in ESRD cases receiving HD.

Background: Bacillus Calmette-Guerin (BCG) immunotherapy is the standard adjuvant treatment for high-risk, non-muscle invasive bladder cancer (NMIBC). However, BCG immunotherapy is commonly accompanied by significant lower urinary tract symptoms (LUTS) including symptoms such as urinary urgency, frequency, dysuria and pelvic pain. These symptoms can undermine treatment adherence and clinical outcomes.

Background: The BCG vaccine induces trained immunity, an epigenetic-mediated increase in innate immune responsiveness. Therefore, this clinical trial evaluated if BCG-induced trained immunity could decrease coronavirus disease 2019 (COVID-19)-related frequency or severity.
Methods: A double-blind, placebo-controlled clinical trial of healthcare workers randomized participants to vaccination with BCG TICE or placebo (saline).

Objectives: Bacille Calmette-Guérin (BCG) vaccination has off-target effects on disease risk for unrelated infections and immune responses to vaccines. This study aimed to determine the immunomodulatory effects of BCG vaccination on immune responses to vaccines against SARS-CoV-2.
Methods: Blood samples, from a subset of 275 SARS-CoV-2-naïve healthcare workers randomised to BCG vaccination (BCG group) or no BCG vaccination (Control group) in the BRACE trial, were collected before and 28 days after the primary course (two doses) of ChAdOx1-S (Oxford-AstraZeneca) or BNT162b2 (Pfizer-BioNTech) vaccination.

The importance of humoral immunity in combating TB has gained extensive recognition. In this study, a subunit vaccine named Ag85A-LpqH (AL) was prepared by fusing the antigen Ag85A proved to induce robust T cell immune responses, and LpqH was shown to produce protective antibodies. The prevention and BCG prime-boost mouse models were established to test the vaccine efficacy.

Bovine tuberculosis is mainly caused by Mycobacterium bovis. Bacillus Calmette-Guérin (BCG) is an attenuated strain of M. bovis which provides variable disease protection.
